-// ### How to create a tracebuffer entry ###
-//
-// If you only need a temporary debugging aid then you can use one of
-// the standard kernel logging events:
-//
-// LOG_MSG(Context *context, const char *msg)
-// - context is something like context_of(this) or current_context()
-// or 0 if there is no context available
-// - msg should be displayed in the tracebuffer view
-//
-// LOG_MSG_3VAL(Context *context, const char *msg,
-// Mword val1, Mword val2, Mword val3)
-// - context and msg can be used the same way LOG_MSG does
-// - val1, val2, and val3 are values that will be displayed in
-// the tracebuffer view as hexadecimal values
-//
-// If you want to create a permanent log event xyz, you have to follow
-// these instructions:
-// - create enum Log_event_xyz (see jdb_ktrace.cpp)
-// - create class Tb_entry_xyz derived from Tb_entry (see tb_entry.cpp)
-// with an appropriate ::set method and with accessor methods
-// - create function formatter_xyz (see tb_entry_output.cpp) and don't
-// forget to register it (add an appropriate line to init_formatters)
-// - create macro LOG_XYZ (see the following example)
-// #define LOG_XYZ
-// BEGIN_LOG_EVENT(log_xyz)
-// Lock_guard <Cpu_lock> guard (&cpu_lock);
-// Tb_entry_xyz *tb =
-// static_cast<Tb_entry_ctx_sw*>(Jdb_tbuf::new_entry());
-// tb->set (this, <some log specific variables>)
-// Jdb_tbuf::commit_entry();
-// END_LOG_EVENT
-// (grabbing the cpu_lock isn't necessary if it is still grabbed)
-// - create an empty macro declaration for CONFIG_JDB_LOGGING=n
-// - insert the macro call into the code
-// - WARNING: permanent log events should _not_ be placed into an inline
-// function!
-// - add
-// DECLARE_PATCH (lp<nn>, log_xyz);
-// static Log_event le<mm>(<description for the 'O' command>,
-// Log_event_xyz, 1, &lp<nn>);
-// and create an entry le<mm> for Jdb_tbuf_events::log_events[]
-// (see jdb_tbuf_events.cpp)

-
-This source release includes:
-
-
-1) a cross-OS AML interpreter
-
-This is intended to allow commercial and open source operating systems
-to be enabled for ACPI. OS specific code is still needed, but the
-AML interpreter should greatly improve the development speed of ACPI
-support.
-
-The AML interpreter source should be integrated into the kernel's
-build process. We recommend establishing an automated method for
-this, so later versions can also be incorporated easily. Please see
-the documentation on the website for API and other implementation
-information.
-
-
-2) iasl, an ASL compiler/decompiler
-
-iasl compiles ASL (ACPI Source Language) into AML (ACPI Machine
-Language). This AML is suitable for inclusion as a DSDT in system
-firmware. It also can disassemble AML, for debugging purposes.
-
-To compile:
-
-cd compiler
-make
-
-It has been compiled on Linux, but should easily port to other Unix
-environments.
-
-Run 'iasl -h' for more information, or download the binary version for
-documentation in PDF format.
-
-
-3) acpisrc, a source code conversion tool
-
-acpisrc converts the standard form of the acpica source release (included
-here) into a version that meets Linux coding guidelines. This consists
-mainly of performing a series of string replacements and transformations
-to the code.
-
-To compile:
-
-cd tools/acpisrc
-make
-
-It has been compiled on Linux, but should easily port to other Unix
-environments.
-
-
-4) acpibin, an AML file tool
-
-acpibin compares AML files, dumps AML binary files to text files,
-extracts binary AML from text files, and other AML file
-manipulation.
-
-To compile:
-
-cd tools/acpibin
-make
-
-
-5) acpiexec, a user-space AML interpreter
-
-acpiexec allows the loading of ACPI tables and execution of control
-methods from user space. Useful for debugging AML code and testing
-the AML interpreter.
-
-To compile:
-
-cd tools/acpiexec
-make
-

-----------------------------------------
-14 December 2009. Summary of changes for version 20091214:
-
-This release is available at www.acpica.org/downloads
-
-1) ACPI CA Core Subsystem:
-
-Enhanced automatic data type conversions for predefined name repairs. This
-change expands the automatic repairs/conversions for predefined name return
-values to make Integers, Strings, and Buffers fully interchangeable. Also, a
-Buffer can be converted to a Package of Integers if necessary. The nsrepair.c
-module was completely restructured. Lin Ming, Bob Moore.
-
-Implemented automatic removal of null package elements during predefined name
-repairs. This change will automatically remove embedded and trailing NULL
-package elements from returned package objects that are defined to contain a
-variable number of sub-packages. The driver is then presented with a package
-with no null elements to deal with. ACPICA BZ 819.
-
-Implemented a repair for the predefined _FDE and _GTM names. The expected
-return value for both names is a Buffer of 5 DWORDs. This repair fixes two
-possible problems (both seen in the field), where a package of integers is
-returned, or a buffer of BYTEs is returned. With assistance from Jung-uk Kim.
-
-Implemented additional module-level code support. This change will properly
-execute module-level code that is not at the root of the namespace (under a
-Device object, etc.). Now executes the code within the current scope instead
-of the root. ACPICA BZ 762. Lin Ming.
-
-Fixed possible mutex acquisition errors when running _REG methods. Fixes a
-problem where mutex errors can occur when running a _REG method that is in
-the same scope as a method-defined operation region or an operation region
-under a module-level IF block. This type of code is rare, so the problem has
-not been seen before. ACPICA BZ 826. Lin Ming, Bob Moore.
-
-Fixed a possible memory leak during module-level code execution. An object
-could be leaked for each block of executed module-level code if the
-interpreter slack mode is enabled This change deletes any implicitly returned
-object from the module-level code block. Lin Ming.
-
-Removed messages for successful predefined repair(s). The repair mechanism
-was considered too wordy. Now, messages are only unconditionally emitted if
-the return object cannot be repaired. Existing messages for successful
-repairs were converted to ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 86.6K Code, 18.2K Data, 104.8K Total
- Debug Version: 162.7K Code, 50.8K Data, 213.5K Total
- Current Release:
- Non-Debug Version: 87.0K Code, 18.0K Data, 105.0K Total
- Debug Version: 163.4K Code, 50.8K Data, 214.2K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-iASL: Fixed a regression introduced in 20091112 where intermediate .SRC files
-were no longer automatically removed at the termination of the compile.
-
-acpiexec: Implemented the -f option to specify default region fill value.
-This option specifies the value used to initialize buffers that simulate
-operation regions. Default value is zero. Useful for debugging problems that
-depend on a specific initial value for a region or field.
-
-----------------------------------------
-12 November 2009. Summary of changes for version 20091112:
-
-This release is available at www.acpica.org/downloads
-
-1) ACPI CA Core Subsystem:
-
-Implemented a post-order callback to AcpiWalkNamespace. The existing
-interface only has a pre-order callback. This change adds an additional
-parameter for a post-order callback which will be more useful for bus scans.
-ACPICA BZ 779. Lin Ming. Updated the ACPICA Programmer Reference.
-
-Modified the behavior of the operation region memory mapping cache for
-SystemMemory. Ensure that the memory mappings created for operation regions
-do not cross 4K page boundaries. Crossing a page boundary while mapping
-regions can cause kernel warnings on some hosts if the pages have different
-attributes. Such regions are probably BIOS bugs, and this is the workaround.
-Linux BZ 14445. Lin Ming.
-
-Implemented an automatic repair for predefined methods that must return
-sorted lists. This change will repair (by sorting) packages returned by _ALR,
-_PSS, and _TSS. Drivers can now assume that the packages are correctly sorted
-and do not contain NULL package elements. Adds one new file,
-namespace/nsrepair2.c. ACPICA BZ 784. Lin Ming, Bob Moore.
-
-Fixed a possible fault during predefined name validation if a return Package
-object contains NULL elements. Also adds a warning if a NULL element is
-followed by any non-null elements. ACPICA BZ 813, 814. Future enhancement may
-include repair or removal of all such NULL elements where possible.
-
-Implemented additional module-level executable AML code support. This change
-will execute module-level code that is not at the root of the namespace
-(under a Device object, etc.) at table load time. Module-level executable AML
-code has been illegal since ACPI 2.0. ACPICA BZ 762. Lin Ming.
-
-Implemented a new internal function to create Integer objects. This function
-simplifies miscellaneous object creation code. ACPICA BZ 823.
-
-Reduced the severity of predefined repair messages, Warning to Info. Since
-the object was successfully repaired, a warning is too severe. Reduced to an
-info message for now. These messages may eventually be changed to debug-only.
-ACPICA BZ 812.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.

-
-2) iASL Compiler/Disassembler and Tools:
-
-iASL: Implemented Switch() with While(1) so that Break works correctly. This
-change correctly implements the Switch operator with a surrounding While(1)
-so that the Break operator works as expected. ACPICA BZ 461. Lin Ming.
-
-iASL: Added a message if a package initializer list is shorter than package
-length. Adds a new remark for a Package() declaration if an initializer list
-exists, but is shorter than the declared length of the package. Although
-technically legal, this is probably a coding error and it is seen in the
-field. ACPICA BZ 815. Lin Ming, Bob Moore.
-
-iASL: Fixed a problem where the compiler could fault after the maximum number
-of errors was reached (200).
-
-acpixtract: Fixed a possible warning for pointer cast if the compiler warning
-level set very high.

-----------------------------------------
-13 October 2009. Summary of changes for version 20091013:
-
-This release is available at www.acpica.org/downloads
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem where an Operation Region _REG method could be executed more
-than once. If a custom address space handler is installed by the host before
-the "initialize operation regions" phase of the ACPICA initialization, any
-_REG methods for that address space could be executed twice. This change
-fixes the problem. ACPICA BZ 427. Lin Ming.
-
-Fixed a possible memory leak for the Scope() ASL operator. When the exact
-invocation of "Scope(\)" is executed (change scope to root), one internal
-operand object was leaked. Lin Ming.
-
-Implemented a run-time repair for the _MAT predefined method. If the _MAT
-return value is defined as a Field object in the AML, and the field
-size is less than or equal to the default width of an integer (32 or 64),_MAT
-can incorrectly return an Integer instead of a Buffer. ACPICA now
-automatically repairs this problem. ACPICA BZ 810.
-
-Implemented a run-time repair for the _BIF and _BIX predefined methods. The
-"OEM Information" field is often incorrectly returned as an Integer with
-value zero if the field is not supported by the platform. This is due to an
-ambiguity in the ACPI specification. The field should always be a string.
-ACPICA now automatically repairs this problem by returning a NULL string
-within the returned Package. ACPICA BZ 807.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.

-
-2) iASL Compiler/Disassembler and Tools:
-
-Disassembler: Fixed a problem where references to external symbols that
-contained one or more parent-prefixes (carats) were not handled correctly,
-possibly causing a fault. ACPICA BZ 806. Lin Ming.
-
-Disassembler: Restructured the code so that all functions that handle
-external symbols are in a single module. One new file is added,
-common/dmextern.c.
-
-AML Debugger: Added a max count argument for the Batch command (which
-executes multiple predefined methods within the namespace.)
-
-iASL: Updated the compiler documentation (User Reference.) Available at
-http://www.acpica.org/documentation/. ACPICA BZ 750.
-
-AcpiXtract: Updated for Lint and other formatting changes. Close all open

-
-----------------------------------------
-03 September 2009. Summary of changes for version 20090903:
-
-1) ACPI CA Core Subsystem:
-
-For Windows Vista compatibility, added the automatic execution of an _INI
-method located at the namespace root (\_INI). This method is executed at
-table load time. This support is in addition to the automatic execution of
-\_SB._INI. Lin Ming.
-
-Fixed a possible memory leak in the interpreter for AML package objects if
-the package initializer list is longer than the defined size of the package.
-This apparently can only happen if the BIOS changes the package size on the
-fly (seen in a _PSS object), as ASL compilers do not allow this. The
-interpreter will truncate the package to the defined size (and issue an error
-message), but previously could leave the extra objects undeleted if they were
-pre-created during the argument processing (such is the case if the package
-consists of a number of sub-packages as in the _PSS.) ACPICA BZ 805.
-
-Fixed a problem seen when a Buffer or String is stored to itself via ASL.
-This has been reported in the field. Previously, ACPICA would zero out the
-buffer/string. Now, the operation is treated as a noop. Provides Windows
-compatibility. ACPICA BZ 803. Lin Ming.
-
-Removed an extraneous error message for ASL constructs of the form
-Store(LocalX,LocalX) when LocalX is uninitialized. These curious statements
-are seen in many BIOSs and are once again treated as NOOPs and no error is
-emitted when they are encountered. ACPICA BZ 785.
-
-Fixed an extraneous warning message if a _DSM reserved method returns a
-Package object. _DSM can return any type of object, so validation on the
-return type cannot be performed. ACPICA BZ 802.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 85.5K Code, 18.0K Data, 103.5K Total
- Debug Version: 161.6K Code, 50.9K Data, 212.5K Total

- Non-Debug Version: 85.6K Code, 18.0K Data, 103.6K Total
- Debug Version: 161.7K Code, 50.9K Data, 212.6K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-iASL: Fixed a problem with the use of the Alias operator and Resource
-Templates. The correct alias is now constructed and no error is emitted.
-ACPICA BZ 738.
-
-iASL: Implemented the -I option to specify additional search directories for
-include files. Allows multiple additional search paths for include files.
-Directories are searched in the order specified on the command line (after
-the local directory is searched.) ACPICA BZ 800.
-
-iASL: Fixed a problem where the full pathname for include files was not
-emitted for warnings/errors. This caused the IDE support to not work
-properly. ACPICA BZ 765.
-
-iASL: Implemented the -@ option to specify a Windows-style response file
-containing additional command line options. ACPICA BZ 801.
-
-AcpiExec: Added support to load multiple AML files simultaneously (such as a
-DSDT and multiple SSDTs). Also added support for wildcards within the AML
-pathname. These features allow all machine tables to be easily loaded and
-debugged together. ACPICA BZ 804.
-
-Disassembler: Added missing support for disassembly of HEST table Error Bank
-subtables.
-
-----------------------------------------
-30 July 2009. Summary of changes for version 20090730:
-
-The ACPI 4.0 implementation for ACPICA is complete with this release.
-
-1) ACPI CA Core Subsystem:
-
-ACPI 4.0: Added header file support for all new and changed ACPI tables.
-Completely new tables are: IBFT, IVRS, MSCT, and WAET. Tables that are new
-for ACPI 4.0, but have previously been supported in ACPICA are: CPEP, BERT,
-EINJ, ERST, and HEST. Other newly supported tables are: UEFI and WDAT. There
-have been some ACPI 4.0 changes to other existing tables. Split the large
-actbl1.h header into the existing actbl2.h header. ACPICA BZ 774.
-
-ACPI 4.0: Implemented predefined name validation for all new names. There are
-31 new names in ACPI 4.0. The predefined validation module was split into two
-files. The new file is namespace/nsrepair.c. ACPICA BZ 770.
-
-Implemented support for so-called "module-level executable code". This is
-executable AML code that exists outside of any control method and is intended
-to be executed at table load time. Although illegal since ACPI 2.0, this type
-of code still exists and is apparently still being created. Blocks of this
-code are now detected and executed as intended. Currently, the code blocks
-must exist under either an If, Else, or While construct; these are the
-typical cases seen in the field. ACPICA BZ 762. Lin Ming.
-
-Implemented an automatic dynamic repair for predefined names that return
-nested Package objects. This applies to predefined names that are defined to
-return a variable-length Package of sub-packages. If the number of sub-
-packages is one, BIOS code is occasionally seen that creates a simple single
-package with no sub-packages. This code attempts to fix the problem by
-wrapping a new package object around the existing package. These methods can
-be repaired: _ALR, _CSD, _HPX, _MLS, _PRT, _PSS, _TRT, and _TSS. ACPICA BZ
-790.
-
-Fixed a regression introduced in 20090625 for the AcpiGetDevices interface.
-The _HID/_CID matching was broken and no longer matched IDs correctly. ACPICA
-BZ 793.
-
-Fixed a problem with AcpiReset where the reset would silently fail if the
-register was one of the protected I/O ports. AcpiReset now bypasses the port
-validation mechanism. This may eventually be driven into the AcpiRead/Write
-interfaces.
-
-Fixed a regression related to the recent update of the AcpiRead/Write
-interfaces. A sleep/suspend could fail if the optional PM2 Control register
-does not exist during an attempt to write the Bus Master Arbitration bit.
-(However, some hosts already delete the code that writes this bit, and the
-code may in fact be obsolete at this date.) ACPICA BZ 799.
-
-Fixed a problem where AcpiTerminate could fault if inadvertently called twice
-in succession. ACPICA BZ 795.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.

-
-2) iASL Compiler/Disassembler and Tools:
-
-ACPI 4.0: Implemented disassembler support for all new ACPI tables and
-changes to existing tables. ACPICA BZ 775.
-
-----------------------------------------
-25 June 2009. Summary of changes for version 20090625:
-
-The ACPI 4.0 Specification was released on June 16 and is available at
-www.acpi.info. ACPICA implementation of ACPI 4.0 is underway and will
-continue for the next few releases.
-
-1) ACPI CA Core Subsystem:
-
-ACPI 4.0: Implemented interpreter support for the IPMI operation region
-address space. Includes support for bi-directional data buffers and an IPMI
-address space handler (to be installed by an IPMI device driver.) ACPICA BZ
-773. Lin Ming.
-
-ACPI 4.0: Added changes for existing ACPI tables - FACS and SRAT. Includes
-support in both the header files and the disassembler.
-
-Completed a major update for the AcpiGetObjectInfo external interface.
-Changes include:
- - Support for variable, unlimited length HID, UID, and CID strings.
- - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
- - Call the _SxW power methods on behalf of a device object.
- - Determine if a device is a PCI root bridge.
- - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
-These changes will require an update to all callers of this interface. See
-the updated ACPICA Programmer Reference for details. One new source file has
-been added - utilities/utids.c. ACPICA BZ 368, 780.
-
-Updated the AcpiRead and AcpiWrite external interfaces to support 64-bit
-transfers. The Value parameter has been extended from 32 bits to 64 bits in
-order to support new ACPI 4.0 tables. These changes will require an update to
-all callers of these interfaces. See the ACPICA Programmer Reference for
-details. ACPICA BZ 768.
-
-Fixed several problems with AcpiAttachData. The handler was not invoked when
-the host node was deleted. The data sub-object was not automatically deleted
-when the host node was deleted. The interface to the handler had an unused
-parameter, this was removed. ACPICA BZ 778.
-
-Enhanced the function that dumps ACPI table headers. All non-printable
-characters in the string fields are now replaced with '?' (Signature, OemId,
-OemTableId, and CompilerId.) ACPI tables with non-printable characters in
-these fields are occasionally seen in the field. ACPICA BZ 788.
-
-Fixed a problem with predefined method repair code where the code that
-attempts to repair/convert an object of incorrect type is only executed on
-the first time the predefined method is called. The mechanism that disables
-warnings on subsequent calls was interfering with the repair mechanism.
-ACPICA BZ 781.
-
-Fixed a possible memory leak in the predefined validation/repair code when a
-buffer is automatically converted to an expected string object.
-
-Removed obsolete 16-bit files from the distribution and from the current git
-tree head. ACPICA BZ 776.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.

-
-2) iASL Compiler/Disassembler and Tools:
-
-ACPI 4.0: iASL and Disassembler - implemented support for the new IPMI
-operation region keyword. ACPICA BZ 771, 772. Lin Ming.
-
-ACPI 4.0: iASL - implemented compile-time validation support for all new
-predefined names and control methods (31 total). ACPICA BZ 769.
-
-----------------------------------------
-21 May 2009. Summary of changes for version 20090521:
-
-1) ACPI CA Core Subsystem:
-
-Disabled the preservation of the SCI enable bit in the PM1 control register.
-The SCI enable bit (bit 0, SCI_EN) is defined by the ACPI specification to be
-a "preserved" bit - "OSPM always preserves this bit position", section
-4.7.3.2.1. However, some machines fail if this bit is in fact preserved
-because the bit needs to be explicitly set by the OS as a workaround. No
-machines fail if the bit is not preserved. Therefore, ACPICA no longer
-attempts to preserve this bit.
-
-Fixed a problem in AcpiRsGetPciRoutingTableLength where an invalid or
-incorrectly formed _PRT package could cause a fault. Added validation to
-ensure that each package element is actually a sub-package.
-
-Implemented a new interface to install or override a single control method,
-AcpiInstallMethod. This interface is useful when debugging in order to repair
-an existing method or to install a missing method without having to override
-the entire ACPI table. See the ACPICA Programmer Reference for use and
-examples. Lin Ming, Bob Moore.
-
-Fixed several reference count issues with the DdbHandle object that is
-created from a Load or LoadTable operator. Prevent premature deletion of the
-object. Also, mark the object as invalid once the table has been unloaded.
-This is needed because the handle itself may not be deleted after the table
-unload, depending on whether it has been stored in a named object by the
-caller. Lin Ming.
-
-Fixed a problem with Mutex Sync Levels. Fixed a problem where if multiple
-mutexes of the same sync level are acquired but then not released in strict
-opposite order, the internally maintained Current Sync Level becomes confused
-and can cause subsequent execution errors. ACPICA BZ 471.
-
-Changed the allowable release order for ASL mutex objects. The ACPI 4.0
-specification has been changed to make the SyncLevel for mutex objects more
-useful. When releasing a mutex, the SyncLevel of the mutex must now be the
-same as the current sync level. This makes more sense than the previous rule
-(SyncLevel less than or equal). This change updates the code to match the
-specification.
-
-Fixed a problem with the local version of the AcpiOsPurgeCache function. The
-(local) cache must be locked during all cache object deletions. Andrew
-Baumann.
-
-Updated the Load operator to use operation region interfaces. This replaces
-direct memory mapping with region access calls. Now, all region accesses go
-through the installed region handler as they should.
-
-Simplified and optimized the NsGetNextNode function. Reduced parameter count
-and reduced code for this frequently used function.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.

- Debug Version: 158.9K Code, 50.0K Data, 208.9K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-Disassembler: Fixed some issues with DMAR, HEST, MADT tables. Some problems
-with sub-table disassembly and handling invalid sub-tables. Attempt recovery
-after an invalid sub-table ID.
-
-----------------------------------------
-22 April 2009. Summary of changes for version 20090422:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a compatibility issue with the recently released I/O port protection
-mechanism. For windows compatibility, 1) On a port protection violation,
-simply ignore the request and do not return an exception (allow the control
-method to continue execution.) 2) If only part of the request overlaps a
-protected port, read/write the individual ports that are not protected. Linux
-BZ 13036. Lin Ming
-
-Enhanced the execution of the ASL/AML BreakPoint operator so that it actually
-breaks into the AML debugger if the debugger is present. This matches the
-ACPI-defined behavior.
-
-Fixed several possible warnings related to the use of the configurable
-ACPI_THREAD_ID. This type can now be configured as either an integer or a
-pointer with no warnings. Also fixes several warnings in printf-like
-statements for the 64-bit build when the type is configured as a pointer.
-ACPICA BZ 766, 767.
-
-Fixed a number of possible warnings when compiling with gcc 4+ (depending on
-warning options.) Examples include printf formats, aliasing, unused globals,
-missing prototypes, missing switch default statements, use of non-ANSI
-library functions, use of non-ANSI constructs. See generate/unix/Makefile for
-a list of warning options used with gcc 3 and 4. ACPICA BZ 735.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:

- Non-Debug Version: 82.8K Code, 17.5K Data, 100.3K Total
- Debug Version: 158.0K Code, 49.9K Data, 207.9K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-iASL: Fixed a generation warning from Bison 2.3 and fixed several warnings on
-the 64-bit build.
-
-iASL: Fixed a problem where the Unix/Linux versions of the compiler could not
-correctly digest Windows/DOS formatted files (with CR/LF).
-
-iASL: Added a new option for "quiet mode" (-va) that produces only the
-compilation summary, not individual errors and warnings. Useful for large
-batch compilations.
-
-AcpiExec: Implemented a new option (-z) to enable a forced semaphore/mutex
-timeout that can be used to detect hang conditions during execution of AML
-code (includes both internal semaphores and AML-defined mutexes and events.)
-
-Added new makefiles for the generation of acpica in a generic unix-like
-environment. These makefiles are intended to generate the acpica tools and
-utilities from the original acpica git source tree structure.
-
-Test Suites: Updated and cleaned up the documentation files. Updated the
-copyrights to 2009, affecting all source files. Use the new version of iASL
-with quiet mode. Increased the number of available semaphores in the Windows
-OSL, allowing the aslts to execute fully on Windows. For the Unix OSL, added
-an alternate implementation of the semaphore timeout to allow aslts to
-execute fully on Cygwin.
-
-----------------------------------------
-20 March 2009. Summary of changes for version 20090320:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a possible race condition between AcpiWalkNamespace and dynamic table
-unloads. Added a reader/writer locking mechanism to allow multiple concurrent
-namespace walks (readers), but block a dynamic table unload until it can gain
-exclusive write access to the namespace. This fixes a problem where a table
-unload could (possibly catastrophically) delete the portion of the namespace
-that is currently being examined by a walk. Adds a new file, utlock.c, that
-implements the reader/writer lock mechanism. ACPICA BZ 749.
-
-Fixed a regression introduced in version 20090220 where a change to the FADT
-handling could cause the ACPICA subsystem to access non-existent I/O ports.
-
-Modified the handling of FADT register and table (FACS/DSDT) addresses. The
-FADT can contain both 32-bit and 64-bit versions of these addresses.
-Previously, the 64-bit versions were favored, meaning that if both 32 and 64
-versions were valid, but not equal, the 64-bit version was used. This was
-found to cause some machines to fail. Now, in this case, the 32-bit version
-is used instead. This now matches the Windows behavior.
-
-Implemented a new mechanism to protect certain I/O ports. Provides Microsoft
-compatibility and protects the standard PC I/O ports from access via AML
-code. Adds a new file, hwvalid.c
-
-Fixed a possible extraneous warning message from the FADT support. The
-message warns of a 32/64 length mismatch between the legacy and GAS
-definitions for a register.
-
-Removed the obsolete AcpiOsValidateAddress OSL interface. This interface is
-made obsolete by the port protection mechanism above. It was previously used
-to validate the entire address range of an operation region, which could be
-incorrect if the range included illegal ports, but fields within the
-operation region did not actually access those ports. Validation is now
-performed on a per-field basis instead of the entire region.
-
-Modified the handling of the PM1 Status Register ignored bit (bit 11.)
-Ignored bits must be "preserved" according to the ACPI spec. Usually, this
-means a read/modify/write when writing to the register. However, for status
-registers, writing a one means clear the event. Writing a zero means preserve
-the event (do not clear.) This behavior is clarified in the ACPI 4.0 spec,
-and the ACPICA code now simply always writes a zero to the ignored bit.
-
-Modified the handling of ignored bits for the PM1 A/B Control Registers. As
-per the ACPI specification, for the control registers, preserve
-(read/modify/write) all bits that are defined as either reserved or ignored.
-
-Updated the handling of write-only bits in the PM1 A/B Control Registers.
-When reading the register, zero the write-only bits as per the ACPI spec.
-ACPICA BZ 443. Lin Ming.
-
-Removed "Linux" from the list of supported _OSI strings. Linux no longer
-wants to reply true to this request. The Windows strings are the only paths
-through the AML that are tested and known to work properly.

-aetables.c
-
-----------------------------------------
-20 February 2009. Summary of changes for version 20090220:
-
-1) ACPI CA Core Subsystem:
-
-Optimized the ACPI register locking. Removed locking for reads from the ACPI
-bit registers in PM1 Status, Enable, Control, and PM2 Control. The lock is
-not required when reading the single-bit registers. The
-AcpiGetRegisterUnlocked function is no longer needed and has been removed.
-This will improve performance for reads on these registers. ACPICA BZ 760.
-
-Fixed the parameter validation for AcpiRead/Write. Now return
-AE_BAD_PARAMETER if the input register pointer is null, and AE_BAD_ADDRESS if
-the register has an address of zero. Previously, these cases simply returned
-AE_OK. For optional registers such as PM1B status/enable/control, the caller
-should check for a valid register address before calling. ACPICA BZ 748.
-
-Renamed the external ACPI bit register access functions. Renamed
-AcpiGetRegister and AcpiSetRegister to clarify the purpose of these
-functions. The new names are AcpiReadBitRegister and AcpiWriteBitRegister.
-Also, restructured the code for these functions by simplifying the code path
-and condensing duplicate code to reduce code size.
-
-Added new functions to transparently handle the possibly split PM1 A/B
-registers. AcpiHwReadMultiple and AcpiHwWriteMultiple. These two functions
-now handle the split registers for PM1 Status, Enable, and Control. ACPICA BZ
-746.
-
-Added a function to handle the PM1 control registers, AcpiHwWritePm1Control.
-This function writes both of the PM1 control registers (A/B). These registers
-are different than the PM1 A/B status and enable registers in that different
-values can be written to the A/B registers. Most notably, the SLP_TYP bits
-can be different, as per the values returned from the _Sx predefined methods.
-
-Removed an extra register write within AcpiHwClearAcpiStatus. This function
-was writing an optional PM1B status register twice. The existing call to the
-low-level AcpiHwRegisterWrite automatically handles a possibly split PM1 A/B
-register. ACPICA BZ 751.
-
-Split out the PM1 Status registers from the FADT. Added new globals for these
-registers (A/B), similar to the way the PM1 Enable registers are handled.
-Instead of overloading the FADT Event Register blocks. This makes the code
-clearer and less prone to error.
-
-Fixed the warning message for when the platform contains too many ACPI tables
-for the default size of the global root table data structure. The calculation
-for the truncation value was incorrect.
-
-Removed the ACPI_GET_OBJECT_TYPE macro. Removed all instances of this
-obsolete macro, since it is now a simple reference to ->common.type. There
-were about 150 invocations of the macro across 41 files. ACPICA BZ 755.
-
-Removed the redundant ACPI_BITREG_SLEEP_TYPE_B. This type is the same as
-TYPE_A. Removed this and all related instances. Renamed SLEEP_TYPE_A to
-simply SLEEP_TYPE. ACPICA BZ 754.
-
-Conditionally compile the AcpiSetFirmwareWakingVector64 function. This
-function is only needed on 64-bit host operating systems and is thus not
-included for 32-bit hosts.
-
-Debug output: print the input and result for invocations of the _OSI reserved
-control method via the ACPI_LV_INFO debug level. Also, reduced some of the
-verbosity of this debug level. Len Brown.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.

-----------------------------------------
-23 January 2009. Summary of changes for version 20090123:
-
-1) ACPI CA Core Subsystem:
-
-Added the 2009 copyright to all module headers and signons. This affects
-virtually every file in the ACPICA core subsystem, the iASL compiler, and
-the tools/utilities.
-
-Implemented a change to allow the host to override any ACPI table, including
-dynamically loaded tables. Previously, only the DSDT could be replaced by the
-host. With this change, the AcpiOsTableOverride interface is called for each
-table found in the RSDT/XSDT during ACPICA initialization, and also whenever
-a table is dynamically loaded via the AML Load operator.
-
-Updated FADT flag definitions, especially the Boot Architecture flags.
-
-Debugger: For the Find command, automatically pad the input ACPI name with
-underscores if the name is shorter than 4 characters. This enables a match
-with the actual namespace entry which is itself padded with underscores.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:

- Non-Debug Version: 82.3K Code, 17.5K Data, 99.8K Total
- Debug Version: 157.3K Code, 49.8K Data, 207.1K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-Fix build error under Bison-2.4.
-
-Dissasembler: Enhanced FADT support. Added decoding of the Boot Architecture
-flags. Now decode all flags, regardless of the FADT version. Flag output
-includes the FADT version which first defined each flag.
-
-The iASL -g option now dumps the RSDT to a file (in addition to the FADT and
-DSDT). Windows only.
-
-----------------------------------------
-04 December 2008. Summary of changes for version 20081204:
-
-1) ACPI CA Core Subsystem:
-
-The ACPICA Programmer Reference has been completely updated and revamped for
-this release. This includes updates to the external interfaces, OSL
-interfaces, the overview sections, and the debugger reference.
-
-Several new ACPICA interfaces have been implemented and documented in the
-programmer reference:
-AcpiReset - Writes the reset value to the FADT-defined reset register.
-AcpiDisableAllGpes - Disable all available GPEs.
-AcpiEnableAllRuntimeGpes - Enable all available runtime GPEs.
-AcpiGetGpeDevice - Get the GPE block device associated with a GPE.
-AcpiGbl_CurrentGpeCount - Tracks the current number of available GPEs.
-AcpiRead - Low-level read ACPI register (was HwLowLevelRead.)
-AcpiWrite - Low-level write ACPI register (was HwLowLevelWrite.)
-
-Most of the public ACPI hardware-related interfaces have been moved to a new
-file, components/hardware/hwxface.c
-
-Enhanced the FADT parsing and low-level ACPI register access: The ACPI
-register lengths within the FADT are now used, and the low level ACPI
-register access no longer hardcodes the ACPI register lengths. Given that
-there may be some risk in actually trusting the FADT register lengths, a run-
-time option was added to fall back to the default hardcoded lengths if the
-FADT proves to contain incorrect values - UseDefaultRegisterWidths. This
-option is set to true for now, and a warning is issued if a suspicious FADT
-register length is overridden with the default value.
-
-Fixed a reference count issue in NsRepairObject. This problem was introduced
-in version 20081031 as part of a fix to repair Buffer objects within
-Packages. Lin Ming.
-
-Added semaphore support to the Linux/Unix application OS-services layer
-(OSL). ACPICA BZ 448. Lin Ming.
-
-Added the ACPI_MUTEX_TYPE configuration option to select whether mutexes will
-be implemented in the OSL, or will binary semaphores be used instead.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 81.7K Code, 17.3K Data, 99.0K Total
- Debug Version: 156.4K Code, 49.4K Data, 205.8K Total
- Current Release:
- Non-Debug Version: 82.3K Code, 17.4K Data, 99.7K Total
- Debug Version: 157.1K Code, 49.7K Data, 206.8K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-iASL: Completed the '-e' option to include additional ACPI tables in order to
-aid with disassembly and External statement generation. ACPICA BZ 742. Lin
-Ming.
-
-iASL: Removed the "named object in while loop" error. The compiler cannot
-determine how many times a loop will execute. ACPICA BZ 730.
-
-Disassembler: Implemented support for FADT revision 2 (MS extension). ACPICA
-BZ 743.
-
-Disassembler: Updates for several ACPI data tables (HEST, EINJ, and MCFG).
-
-----------------------------------------
-31 October 2008. Summary of changes for version 20081031:
-
-1) ACPI CA Core Subsystem:
-
-Restructured the ACPICA header files into public/private. acpi.h now includes
-only the "public" acpica headers. All other acpica headers are "private" and
-should not be included by acpica users. One new file, accommon.h is used to
-include the commonly used private headers for acpica code generation. Future
-plans include moving all private headers to a new subdirectory.
-
-Implemented an automatic Buffer->String return value conversion for
-predefined ACPI methods. For these methods (such as _BIF), added automatic
-conversion for return objects that are required to be a String, but a Buffer
-was found instead. This can happen when reading string battery data from an
-operation region, because it used to be difficult to convert the data from
-buffer to string from within the ASL. Ensures that the host OS is provided
-with a valid null-terminated string. Linux BZ 11822.
-
-Updated the FACS waking vector interfaces. Split AcpiSetFirmwareWakingVector
-into two: one for the 32-bit vector, another for the 64-bit vector. This is
-required because the host OS must setup the wake much differently for each
-vector (real vs. protected mode, etc.) and the interface itself should not be
-deciding which vector to use. Also, eliminated the GetFirmwareWakingVector
-interface, as it served no purpose (only the firmware reads the vector, OS
-only writes the vector.) ACPICA BZ 731.
-
-Implemented a mechanism to escape infinite AML While() loops. Added a loop
-counter to force exit from AML While loops if the count becomes too large.
-This can occur in poorly written AML when the hardware does not respond
-within a while loop and the loop does not implement a timeout. The maximum
-loop count is configurable. A new exception code is returned when a loop is
-broken, AE_AML_INFINITE_LOOP. Alexey Starikovskiy, Bob Moore.
-
-Optimized the execution of AML While loops. Previously, a control state
-object was allocated and freed for each execution of the loop. The
-optimization is to simply reuse the control state for each iteration. This
-speeds up the raw loop execution time by about 5%.
-
-Enhanced the implicit return mechanism. For Windows compatibility, return an
-implicit integer of value zero for methods that contain no executable code.
-Such methods are seen in the field as stubs (presumably), and can cause
-drivers to fail if they expect a return value. Lin Ming.
-
-Allow multiple backslashes as root prefixes in namepaths. In a fully
-qualified namepath, allow multiple backslash prefixes. This can happen (and
-is seen in the field) because of the use of a double-backslash in strings
-(since backslash is the escape character) causing confusion. ACPICA BZ 739
-Lin Ming.
-
-Emit a warning if two different FACS or DSDT tables are discovered in the
-FADT. Checks if there are two valid but different addresses for the FACS and
-DSDT within the FADT (mismatch between the 32-bit and 64-bit fields.)
-
-Consolidated the method argument count validation code. Merged the code that
-validates control method argument counts into the predefined validation
-module. Eliminates possible multiple warnings for incorrect argument counts.
-
-Implemented ACPICA example code. Includes code for ACPICA initialization,
-handler installation, and calling a control method. Available at
-source/tools/examples.
-
-Added a global pointer for FACS table to simplify internal FACS access. Use
-the global pointer instead of using AcpiGetTableByIndex for each FACS access.
-This simplifies the code for the Global Lock and the Firmware Waking
-Vector(s).
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 81.2K Code, 17.0K Data, 98.2K Total
- Debug Version: 155.8K Code, 49.1K Data, 204.9K Total
- Current Release:
- Non-Debug Version: 81.7K Code, 17.3K Data, 99.0K Total
- Debug Version: 156.4K Code, 49.4K Data, 205.8K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-iASL: Improved disassembly of external method calls. Added the -e option to
-allow the inclusion of additional ACPI tables to help with the disassembly of
-method invocations and the generation of external declarations during the
-disassembly. Certain external method invocations cannot be disassembled
-properly without the actual declaration of the method. Use the -e option to
-include the table where the external method(s) are actually declared. Most
-useful for disassembling SSDTs that make method calls back to the master
-DSDT. Lin Ming. Example: To disassemble an SSDT with calls to DSDT: iasl -d
--e dsdt.aml ssdt1.aml
-
-iASL: Fix to allow references to aliases within ASL namepaths. Fixes a
-problem where the use of an alias within a namepath would result in a not
-found error or cause the compiler to fault. Also now allows forward
-references from the Alias operator itself. ACPICA BZ 738.
-
-----------------------------------------
-26 September 2008. Summary of changes for version 20080926:
-
-1) ACPI CA Core Subsystem:
-
-Designed and implemented a mechanism to validate predefined ACPI methods and
-objects. This code validates the predefined ACPI objects (objects whose names
-start with underscore) that appear in the namespace, at the time they are
-evaluated. The argument count and the type of the returned object are
-validated against the ACPI specification. The purpose of this validation is
-to detect problems with the BIOS-implemented predefined ACPI objects before
-the results are returned to the ACPI-related drivers. Future enhancements may
-include actual repair of incorrect return objects where possible. Two new
-files are nspredef.c and acpredef.h.
-
-Fixed a fault in the AML parser if a memory allocation fails during the Op
-completion routine AcpiPsCompleteThisOp. Lin Ming. ACPICA BZ 492.
-
-Fixed an issue with implicit return compatibility. This change improves the
-implicit return mechanism to be more compatible with the MS interpreter. Lin
-Ming, ACPICA BZ 349.
-
-Implemented support for zero-length buffer-to-string conversions. Allow zero
-length strings during interpreter buffer-to-string conversions. For example,
-during the ToDecimalString and ToHexString operators, as well as implicit
-conversions. Fiodor Suietov, ACPICA BZ 585.
-
-Fixed two possible memory leaks in the error exit paths of
-AcpiUtUpdateObjectReference and AcpiUtWalkPackageTree. These functions are
-similar in that they use a stack of state objects in order to eliminate
-recursion. The stack must be fully unwound and deallocated if an error
-occurs. Lin Ming. ACPICA BZ 383.
-
-Removed the unused ACPI_BITREG_WAKE_ENABLE definition and entry in the global
-ACPI register table. This bit does not exist and is unused. Lin Ming, Bob
-Moore ACPICA BZ 442.
-
-Removed the obsolete version number in module headers. Removed the
-"$Revision" number that appeared in each module header. This version number
-was useful under SourceSafe and CVS, but has no meaning under git. It is not
-only incorrect, it could also be misleading.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 79.7K Code, 16.4K Data, 96.1K Total
- Debug Version: 153.7K Code, 48.2K Data, 201.9K Total
- Current Release:
- Non-Debug Version: 81.2K Code, 17.0K Data, 98.2K Total
- Debug Version: 155.8K Code, 49.1K Data, 204.9K Total
-
-----------------------------------------
-29 August 2008. Summary of changes for version 20080829:
-
-1) ACPI CA Core Subsystem:
-
-Completed a major cleanup of the internal ACPI_OPERAND_OBJECT of type
-Reference. Changes include the elimination of cheating on the Object field
-for the DdbHandle subtype, addition of a reference class field to
-differentiate the various reference types (instead of an AML opcode), and the
-cleanup of debug output for this object. Lin Ming, Bob Moore. BZ 723
-
-Reduce an error to a warning for an incorrect method argument count.
-Previously aborted with an error if too few arguments were passed to a
-control method via the external ACPICA interface. Now issue a warning instead
-and continue. Handles the case where the method inadvertently declares too
-many arguments, but does not actually use the extra ones. Applies mainly to
-the predefined methods. Lin Ming. Linux BZ 11032.
-
-Disallow the evaluation of named object types with no intrinsic value. Return
-AE_TYPE for objects that have no value and therefore evaluation is undefined:
-Device, Event, Mutex, Region, Thermal, and Scope. Previously, evaluation of
-these types were allowed, but an exception would be generated at some point
-during the evaluation. Now, the error is generated up front.
-
-Fixed a possible memory leak in the AcpiNsGetExternalPathname function
-(nsnames.c). Fixes a leak in the error exit path.
-
-Removed the obsolete debug levels ACPI_DB_WARN and ACPI_DB_ERROR. These debug
-levels were made obsolete by the ACPI_WARNING, ACPI_ERROR, and ACPI_EXCEPTION
-interfaces. Also added ACPI_DB_EVENTS to correspond with the existing
-ACPI_LV_EVENTS.
-
-Removed obsolete and/or unused exception codes from the acexcep.h header.
-There is the possibility that certain device drivers may be affected if they
-use any of these exceptions.
-
-The ACPICA documentation has been added to the public git source tree, under
-acpica/documents. Included are the ACPICA programmer reference, the iASL
-compiler reference, and the changes.txt release logfile.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 79.7K Code, 16.4K Data, 96.1K Total
- Debug Version: 153.9K Code, 48.4K Data, 202.3K Total
- Current Release:
- Non-Debug Version: 79.7K Code, 16.4K Data, 96.1K Total
- Debug Version: 153.7K Code, 48.2K Data, 201.9K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-Allow multiple argument counts for the predefined _SCP method. ACPI 3.0
-defines _SCP with 3 arguments. Previous versions defined it with only 1
-argument. iASL now allows both definitions.
-
-iASL/disassembler: avoid infinite loop on bad ACPI tables. Check for zero-
-length subtables when disassembling ACPI tables. Also fixed a couple of
-errors where a full 16-bit table type field was not extracted from the input
-properly.
-
-acpisrc: Improve comment counting mechanism for generating source code
-statistics. Count first and last lines of multi-line comments as whitespace,
-not comment lines. Handle Linux legal header in addition to standard acpica
-header.
-
-----------------------------------------
-
-29 July 2008. Summary of changes for version 20080729:
-
-This release is available at http://acpica.org/downloads
-Direct git access via http://www.acpica.org/repos/acpica.git
-
-1) ACPI CA Core Subsystem:
-
-Fix a possible deadlock in the GPE dispatch. Remove call to
-AcpiHwDisableAllGpes during wake in AcpiEvGpeDispatch. This call will attempt
-to acquire the GPE lock but can deadlock since the GPE lock is already held
-at dispatch time. This code was introduced in version 20060831 as a response
-to Linux BZ 6881 and has since been removed from Linux.
-
-Add a function to dereference returned reference objects. Examines the return
-object from a call to AcpiEvaluateObject. Any Index or RefOf references are
-automatically dereferenced in an attempt to return something useful (these
-reference types cannot be converted into an external ACPI_OBJECT.) Provides
-MS compatibility. Lin Ming, Bob Moore. Linux BZ 11105
-
-x2APIC support: changes for MADT and SRAT ACPI tables. There are 2 new
-subtables for the MADT and one new subtable for the SRAT. Includes
-disassembler and AcpiSrc support. Data from the Intel 64 Architecture x2APIC
-Specification, June 2008.
-
-Additional error checking for pathname utilities. Add error check after all
-calls to AcpiNsGetPathnameLength. Add status return from
-AcpiNsBuildExternalPath and check after all calls. Add parameter validation
-to AcpiUtInitializeBuffer. Reported by and initial patch by Ingo Molnar.
-
-Return status from the global init function AcpiUtGlobalInitialize. This is
-used by both the kernel subsystem and the utilities such as iASL compiler.
-The function could possibly fail when the caches are initialized. Yang Yi.
-
-Add a function to decode reference object types to strings. Created for
-improved error messages.
-
-Improve object conversion error messages. Better error messages during object
-conversion from internal to the external ACPI_OBJECT. Used for external calls
-to AcpiEvaluateObject.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 79.6K Code, 16.2K Data, 95.8K Total
- Debug Version: 153.5K Code, 48.2K Data, 201.7K Total
- Current Release:
- Non-Debug Version: 79.7K Code, 16.4K Data, 96.1K Total
- Debug Version: 153.9K Code, 48.4K Data, 202.3K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-Debugger: fix a possible hang when evaluating non-methods. Fixes a problem
-introduced in version 20080701. If the object being evaluated (via execute
-command) is not a method, the debugger can hang while trying to obtain non-
-existent parameters.
-
-iASL: relax error for using reserved "_T_x" identifiers. These names can
-appear in a disassembled ASL file if they were emitted by the original
-compiler. Instead of issuing an error or warning and forcing the user to
-manually change these names, issue a remark instead.
-
-iASL: error if named object created in while loop. Emit an error if any named
-object is created within a While loop. If allowed, this code will generate a
-run-time error on the second iteration of the loop when an attempt is made to
-create the same named object twice. ACPICA bugzilla 730.
-
-iASL: Support absolute pathnames for include files. Add support for absolute
-pathnames within the Include operator. previously, only relative pathnames
-were supported.
-
-iASL: Enforce minimum 1 interrupt in interrupt macro and Resource Descriptor.
-The ACPI spec requires one interrupt minimum. BZ 423
-
-iASL: Handle a missing ResourceSource arg, with a present SourceIndex.
-Handles the case for the Interrupt Resource Descriptor where
-the ResourceSource argument is omitted but ResourceSourceIndex
-is present. Now leave room for the Index. BZ 426
-
-iASL: Prevent error message if CondRefOf target does not exist. Fixes cases
-where an error message is emitted if the target does not exist. BZ 516
-
-iASL: Fix broken -g option (get Windows ACPI tables). Fixes the -g option
-(get ACPI tables on Windows). This was apparently broken in version 20070919.
-
-AcpiXtract: Handle EOF while extracting data. Correctly handle the case where
-the EOF happens immediately after the last table in the input file. Print
-completion message. Previously, no message was displayed in this case.
-
-----------------------------------------
-01 July 2008. Summary of changes for version 20080701:
-
-This release is available at http://acpica.org/downloads
-Direct git access via http://www.acpica.org/repos/acpica.git
-
-0) Git source tree / acpica.org
-
-Fixed a problem where a git-clone from http would not transfer the entire
-source tree.
-
-1) ACPI CA Core Subsystem:
-
-Implemented a "careful" GPE disable in AcpiEvDisableGpe, only modify one
-enable bit. Now performs a read-change-write of the enable register instead
-of simply writing out the cached enable mask. This will prevent inadvertent
-enabling of GPEs if a rogue GPE is received during initialization (before GPE
-handlers are installed.)
-
-Implemented a copy for dynamically loaded tables. Previously, dynamically
-loaded tables were simply mapped - but on some machines this memory is
-corrupted after suspend. Now copy the table to a local buffer. For the
-OpRegion case, added checksum verify. Use the table length from the table
-header, not the region length. For the Buffer case, use the table length
-also. Dennis Noordsij, Bob Moore. BZ 10734
-
-Fixed a problem where the same ACPI table could not be dynamically loaded and
-unloaded more than once. Without this change, a table cannot be loaded again
-once it has been loaded/unloaded one time. The current mechanism does not
-unregister a table upon an unload. During a load, if the same table is found,
-this no longer returns an exception. BZ 722
-
-Fixed a problem where the wrong descriptor length was calculated for the
-EndTag descriptor in 64-bit mode. The "minimal" descriptors such as EndTag
-are calculated as 12 bytes long, but the actual length in the internal
-descriptor is 16 because of the round-up to 8 on the 64-bit build. Reported
-by Linn Crosetto. BZ 728
-
-Fixed a possible memory leak in the Unload operator. The DdbHandle returned
-by Load() did not have its reference count decremented during unload, leading
-to a memory leak. Lin Ming. BZ 727
-
-Fixed a possible memory leak when deleting thermal/processor objects. Any
-associated notify handlers (and objects) were not being deleted. Fiodor
-Suietov. BZ 506
-
-Fixed the ordering of the ASCII names in the global mutex table to match the
-actual mutex IDs. Used by AcpiUtGetMutexName, a function used for debug only.
-Vegard Nossum. BZ 726
-
-Enhanced the AcpiGetObjectInfo interface to return the number of required
-arguments if the object is a control method. Added this call to the debugger
-so the proper number of default arguments are passed to a method. This
-prevents a warning when executing methods from AcpiExec.
-
-Added a check for an invalid handle in AcpiGetObjectInfo. Return
-AE_BAD_PARAMETER if input handle is invalid. BZ 474
-
-Fixed an extraneous warning from exconfig.c on the 64-bit build.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.

-
-2) iASL Compiler/Disassembler and Tools:
-
-iASL: Added two missing ACPI reserved names. Added _MTP and _ASZ, both
-resource descriptor names.
-
-iASL: Detect invalid ASCII characters in input (windows version). Removed the
-"-CF" flag from the flex compile, enables correct detection of non-ASCII
-characters in the input. BZ 441
-
-iASL: Eliminate warning when result of LoadTable is not used. Eliminate the
-"result of operation not used" warning when the DDB handle returned from
-LoadTable is not used. The warning is not needed. BZ 590
-
-AcpiExec: Add support for dynamic table load/unload. Now calls _CFG method to
-pass address of table to the AML. Added option to disable OpRegion simulation
-to allow creation of an OpRegion with a real address that was passed to _CFG.
-All of this allows testing of the Load and Unload operators from AcpiExec.
-
-Debugger: update tables command for unloaded tables. Handle unloaded tables
-and use the standard table header output routine.
-
-----------------------------------------
-09 June 2008. Summary of changes for version 20080609:
-
-1) ACPI CA Core Subsystem:
-
-Implemented a workaround for reversed _PRT entries. A significant number of
-BIOSs erroneously reverse the _PRT SourceName and the SourceIndex. This
-change dynamically detects and repairs this problem. Provides compatibility
-with MS ACPI. BZ 6859
-
-Simplified the internal ACPI hardware interfaces to eliminate the locking
-flag parameter from Register Read/Write. Added a new external interface,
-AcpiGetRegisterUnlocked.
-
-Fixed a problem where the invocation of a GPE control method could hang. This
-was a regression introduced in 20080514. The new method argument count
-validation mechanism can enter an infinite loop when a GPE method is
-dispatched. Problem fixed by removing the obsolete code that passed GPE block
-information to the notify handler via the control method parameter pointer.
-
-Fixed a problem where the _SST execution status was incorrectly returned to
-the caller of AcpiEnterSleepStatePrep. This was a regression introduced in
-20080514. _SST is optional and a NOT_FOUND exception should never be
-returned. BZ 716
-
-Fixed a problem where a deleted object could be accessed from within the AML
-parser. This was a regression introduced in version 20080123 as a fix for the
-Unload operator. Lin Ming. BZ 10669
-
-Cleaned up the debug operand dump mechanism. Eliminated unnecessary operands
-and eliminated the use of a negative index in a loop. Operands are now
-displayed in the correct order, not backwards. This also fixes a regression
-introduced in 20080514 on 64-bit systems where the elimination of
-ACPI_NATIVE_UINT caused the negative index to go large and positive. BZ 715
-
-Fixed a possible memory leak in EvPciConfigRegionSetup where the error exit
-path did not delete a locally allocated structure.
-
-Updated definitions for the DMAR and SRAT tables to synchronize with the
-current specifications. Includes disassembler support.
-
-Fixed a problem in the mutex debug code (in utmutex.c) where an incorrect
-loop termination value was used. Loop terminated on iteration early, missing
-one mutex. Linn Crosetto
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 79.5K Code, 16.2K Data, 95.7K Total
- Debug Version: 153.3K Code, 48.3K Data, 201.6K Total
- Current Release:
- Non-Debug Version: 79.3K Code, 16.2K Data, 95.5K Total
- Debug Version: 153.0K Code, 48.2K Data, 201.2K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-Disassembler: Implemented support for EisaId() within _CID objects. Now
-disassemble integer _CID objects back to EisaId invocations, including
-multiple integers within _CID packages. Includes single-step support for
-debugger also.
-
-Disassembler: Added support for DMAR and SRAT table definition changes.
-
-----------------------------------------
-14 May 2008. Summary of changes for version 20080514:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem where GPEs were enabled too early during the ACPICA
-initialization. This could lead to "handler not installed" errors on some
-machines. Moved GPE enable until after _REG/_STA/_INI methods are run. This
-ensures that all operation regions and devices throughout the namespace have
-been initialized before GPEs are enabled. Alexey Starikovskiy, BZ 9916.
-
-Implemented a change to the enter sleep code. Moved execution of the _GTS
-method to just before setting sleep enable bit. The execution was moved from
-AcpiEnterSleepStatePrep to AcpiEnterSleepState. _GTS is now executed
-immediately before the SLP_EN bit is set, as per the ACPI specification.
-Luming Yu, BZ 1653.
-
-Implemented a fix to disable unknown GPEs (2nd version). Now always disable
-the GPE, even if ACPICA thinks that that it is already disabled. It is
-possible that the AML or some other code has enabled the GPE unbeknownst to
-the ACPICA code.
-
-Fixed a problem with the Field operator where zero-length fields would return
-an AE_AML_NO_OPERAND exception during table load. Fix enables zero-length ASL
-field declarations in Field(), BankField(), and IndexField(). BZ 10606.
-
-Implemented a fix for the Load operator, now load the table at the namespace
-root. This reverts a change introduced in version 20071019. The table is now
-loaded at the namespace root even though this goes against the ACPI
-specification. This provides compatibility with other ACPI implementations.
-The ACPI specification will be updated to reflect this in ACPI 4.0. Lin Ming.
-
-Fixed a problem where ACPICA would not Load() tables with unusual signatures.
-Now ignore ACPI table signature for Load() operator. Only "SSDT" is
-acceptable to the ACPI spec, but tables are seen with OEMx and null sigs.
-Therefore, signature validation is worthless. Apparently MS ACPI accepts such
-signatures, ACPICA must be compatible. BZ 10454.
-
-Fixed a possible negative array index in AcpiUtValidateException. Added NULL
-fields to the exception string arrays to eliminate a -1 subtraction on the
-SubStatus field.
-
-Updated the debug tracking macros to reduce overall code and data size.
-Changed ACPI_MODULE_NAME and ACPI_FUNCTION_NAME to use arrays of strings
-instead of pointers to static strings. Jan Beulich and Bob Moore.
-
-Implemented argument count checking in control method invocation via
-AcpiEvaluateObject. Now emit an error if too few arguments, warning if too
-many. This applies only to extern programmatic control method execution, not
-method-to-method calls within the AML. Lin Ming.
-
-Eliminated the ACPI_NATIVE_UINT type across all ACPICA code. This type is no
-longer needed, especially with the removal of 16-bit support. It was replaced
-mostly with UINT32, but also ACPI_SIZE where a type that changes 32/64 bit on
-32/64-bit platforms is required.
-
-Added the C const qualifier for appropriate string constants -- mostly
-MODULE_NAME and printf format strings. Jan Beulich.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has a
-much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 80.0K Code, 17.4K Data, 97.4K Total
- Debug Version: 159.4K Code, 64.4K Data, 223.8K Total
- Current Release:
- Non-Debug Version: 79.5K Code, 16.2K Data, 95.7K Total
- Debug Version: 153.3K Code, 48.3K Data, 201.6K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-Implemented ACPI table revision ID validation in the disassembler. Zero is
-always invalid. For DSDTs, the ID controls the interpreter integer width. 1
-means 32-bit and this is unusual. 2 or greater is 64-bit.
-
-----------------------------------------
-21 March 2008. Summary of changes for version 20080321:
-
-1) ACPI CA Core Subsystem:
-
-Implemented an additional change to the GPE support in order to suppress
-spurious or stray GPEs. The AcpiEvDisableGpe function will now permanently
-disable incoming GPEs that are neither enabled nor disabled -- meaning that
-the GPE is unknown to the system. This should prevent future interrupt floods
-from that GPE. BZ 6217 (Zhang Rui)
-
-Fixed a problem where NULL package elements were not returned to the
-AcpiEvaluateObject interface correctly. The element was simply ignored
-instead of returning a NULL ACPI_OBJECT package element, potentially causing
-a buffer overflow and/or confusing the caller who expected a fixed number of
-elements. BZ 10132 (Lin Ming, Bob Moore)
-
-Fixed a problem with the CreateField, CreateXXXField (Bit, Byte, Word, Dword,
-Qword), Field, BankField, and IndexField operators when invoked from inside
-an executing control method. In this case, these operators created namespace
-nodes that were incorrectly left marked as permanent nodes instead of
-temporary nodes. This could cause a problem if there is race condition
-between an exiting control method and a running namespace walk. (Reported by
-Linn Crosetto)
-
-Fixed a problem where the CreateField and CreateXXXField operators would
-incorrectly allow duplicate names (the name of the field) with no exception
-generated.
-
-Implemented several changes for Notify handling. Added support for new Notify
-values (ACPI 2.0+) and improved the Notify debug output. Notify on
-PowerResource objects is no longer allowed, as per the ACPI specification.
-(Bob Moore, Zhang Rui)
-
-All Reference Objects returned via the AcpiEvaluateObject interface are now
-marked as type "REFERENCE" instead of "ANY". The type ANY is now reserved for
-NULL objects - either NULL package elements or unresolved named references.
-
-Fixed a problem where an extraneous debug message was produced for package
-objects (when debugging enabled). The message "Package List length larger
-than NumElements count" is now produced in the correct case, and is now an
-error message rather than a debug message. Added a debug message for the
-opposite case, where NumElements is larger than the Package List (the package
-will be padded out with NULL elements as per the ACPI spec.)
-
-Implemented several improvements for the output of the ASL "Debug" object to
-clarify and keep all data for a given object on one output line.
-
-Fixed two size calculation issues with the variable-length Start Dependent
-resource descriptor.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 79.7K Code, 17.3K Data, 97.0K Total
- Debug Version: 158.9K Code, 64.0K Data, 222.9K Total
- Current Release:
- Non-Debug Version: 80.0K Code, 17.4K Data, 97.4K Total
- Debug Version: 159.4K Code, 64.4K Data, 223.8K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-Fixed a problem with the use of the Switch operator where execution of the
-containing method by multiple concurrent threads could cause an
-AE_ALREADY_EXISTS exception. This is caused by the fact that there is no
-actual Switch opcode, it must be simulated with local named temporary
-variables and if/else pairs. The solution chosen was to mark any method that
-uses Switch as Serialized, thus preventing multiple thread entries. BZ 469.
-
-----------------------------------------
-13 February 2008. Summary of changes for version 20080213:
-
-1) ACPI CA Core Subsystem:
-
-Implemented another MS compatibility design change for GPE/Notify handling.
-GPEs are now cleared/enabled asynchronously to allow all pending notifies to
-complete first. It is expected that the OSL will queue the enable request
-behind all pending notify requests (may require changes to the local host OSL
-in AcpiOsExecute). Alexey Starikovskiy.
-
-Fixed a problem where buffer and package objects passed as arguments to a
-control method via the external AcpiEvaluateObject interface could cause an
-AE_AML_INTERNAL exception depending on the order and type of operators
-executed by the target control method.
-
-Fixed a problem where resource descriptor size optimization could cause a
-problem when a _CRS resource template is passed to a _SRS method. The _SRS
-resource template must use the same descriptors (with the same size) as
-returned from _CRS. This change affects the following resource descriptors:
-IRQ / IRQNoFlags and StartDependendentFn / StartDependentFnNoPri. (BZ 9487)
-
-Fixed a problem where a CopyObject to RegionField, BankField, and IndexField
-objects did not perform an implicit conversion as it should. These types must
-retain their initial type permanently as per the ACPI specification. However,
-a CopyObject to all other object types should not perform an implicit
-conversion, as per the ACPI specification. (Lin Ming, Bob Moore) BZ 388
-
-Fixed a problem with the AcpiGetDevices interface where the mechanism to
-match device CIDs did not examine the entire list of available CIDs, but
-instead aborted on the first non-matching CID. Andrew Patterson.
-
-Fixed a regression introduced in version 20071114. The ACPI_HIDWORD macro was
-inadvertently changed to return a 16-bit value instead of a 32-bit value,
-truncating the upper dword of a 64-bit value. This macro is only used to
-display debug output, so no incorrect calculations were made. Also,
-reimplemented the macro so that a 64-bit shift is not performed by
-inefficient compilers.
-
-Added missing va_end statements that should correspond with each va_start
-statement.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 79.5K Code, 17.2K Data, 96.7K Total
- Debug Version: 159.0K Code, 63.8K Data, 222.8K Total
- Current Release:
- Non-Debug Version: 79.7K Code, 17.3K Data, 97.0K Total
- Debug Version: 158.9K Code, 64.0K Data, 222.9K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-Implemented full disassembler support for the following new ACPI tables:
-BERT, EINJ, and ERST. Implemented partial disassembler support for the
-complicated HEST table. These tables support the Windows Hardware Error
-Architecture (WHEA).
-
-----------------------------------------
-23 January 2008. Summary of changes for version 20080123:
-
-1) ACPI CA Core Subsystem:
-
-Added the 2008 copyright to all module headers and signons. This affects
-virtually every file in the ACPICA core subsystem, the iASL compiler, and
-the tools/utilities.
-
-Fixed a problem with the SizeOf operator when used with Package and Buffer
-objects. These objects have deferred execution for some arguments, and the
-execution is now completed before the SizeOf is executed. This problem caused
-unexpected AE_PACKAGE_LIMIT errors on some systems (Lin Ming, Bob Moore) BZ
-9558
-
-Implemented an enhancement to the interpreter "slack mode". In the absence of
-an explicit return or an implicitly returned object from the last executed
-opcode, a control method will now implicitly return an integer of value 0 for
-Microsoft compatibility. (Lin Ming) BZ 392
-
-Fixed a problem with the Load operator where an exception was not returned in
-the case where the table is already loaded. (Lin Ming) BZ 463
-
-Implemented support for the use of DDBHandles as an Indexed Reference, as per
-the ACPI spec. (Lin Ming) BZ 486
-
-Implemented support for UserTerm (Method invocation) for the Unload operator
-as per the ACPI spec. (Lin Ming) BZ 580
-
-Fixed a problem with the LoadTable operator where the OemId and OemTableId
-input strings could cause unexpected failures if they were shorter than the
-maximum lengths allowed. (Lin Ming, Bob Moore) BZ 576
-
-Implemented support for UserTerm (Method invocation) for the Unload operator
-as per the ACPI spec. (Lin Ming) BZ 580
-
-Implemented header file support for new ACPI tables - BERT, ERST, EINJ, HEST,
-IBFT, UEFI, WDAT. Disassembler support is forthcoming.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 79.3K Code, 17.2K Data, 96.5K Total
- Debug Version: 158.6K Code, 63.8K Data, 222.4K Total
- Current Release:
- Non-Debug Version: 79.5K Code, 17.2K Data, 96.7K Total
- Debug Version: 159.0K Code, 63.8K Data, 222.8K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-Implemented support in the disassembler for checksum validation on incoming
-binary DSDTs and SSDTs. If incorrect, a message is displayed within the table
-header dump at the start of the disassembly.
-
-Implemented additional debugging information in the namespace listing file
-created during compilation. In addition to the namespace hierarchy, the full
-pathname to each namespace object is displayed.
-
-Fixed a problem with the disassembler where invalid ACPI tables could cause
-faults or infinite loops.
-
-Fixed an unexpected parse error when using the optional "parameter types"
-list in a control method declaration. (Lin Ming) BZ 397
-
-Fixed a problem where two External declarations with the same name did not
-cause an error (Lin Ming) BZ 509
-
-Implemented support for full TermArgs (adding Argx, Localx and method
-invocation) for the ParameterData parameter to the LoadTable operator. (Lin
-Ming) BZ 583,587
-
-----------------------------------------
-19 December 2007. Summary of changes for version 20071219:
-
-1) ACPI CA Core Subsystem:
-
-Implemented full support for deferred execution for the TermArg string
-arguments for DataTableRegion. This enables forward references and full
-operand resolution for the three string arguments. Similar to OperationRegion
-deferred argument execution.) Lin Ming. BZ 430
-
-Implemented full argument resolution support for the BankValue argument to
-BankField. Previously, only constants were supported, now any TermArg may be
-used. Lin Ming BZ 387, 393
-
-Fixed a problem with AcpiGetDevices where the search of a branch of the
-device tree could be terminated prematurely. In accordance with the ACPI
-specification, the search down the current branch is terminated if a device
-is both not present and not functional (instead of just not present.) Yakui
-Zhao.
-
-Fixed a problem where "unknown" GPEs could be allowed to fire repeatedly if
-the underlying AML code changed the GPE enable registers. Now, any unknown
-incoming GPE (no _Lxx/_Exx method and not the EC GPE) is immediately disabled
-instead of simply ignored. Rui Zhang.
-
-Fixed a problem with Index Fields where the Index register was incorrectly
-limited to a maximum of 32 bits. Now any size may be used.
-
-Fixed a couple memory leaks associated with "implicit return" objects when
-the AML Interpreter slack mode is enabled. Lin Ming BZ 349
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 79.0K Code, 17.2K Data, 96.2K Total

- Non-Debug Version: 79.3K Code, 17.2K Data, 96.5K Total
- Debug Version: 158.6K Code, 63.8K Data, 222.4K Total
-
-----------------------------------------
-14 November 2007. Summary of changes for version 20071114:
-
-1) ACPI CA Core Subsystem:
-
-Implemented event counters for each of the Fixed Events, the ACPI SCI
-(interrupt) itself, and control methods executed. Named
-AcpiFixedEventCount[], AcpiSciCount, and AcpiMethodCount respectively. These
-should be useful for debugging and statistics.
-
-Implemented a new external interface, AcpiGetStatistics, to retrieve the
-contents of the various event counters. Returns the current values for
-AcpiSciCount, AcpiGpeCount, the AcpiFixedEventCount array, and
-AcpiMethodCount. The interface can be expanded in the future if new counters
-are added. Device drivers should use this interface rather than access the
-counters directly.
-
-Fixed a problem with the FromBCD and ToBCD operators. With some compilers,
-the ShortDivide function worked incorrectly, causing problems with the BCD
-functions with large input values. A truncation from 64-bit to 32-bit
-inadvertently occurred. Internal BZ 435. Lin Ming
-
-Fixed a problem with Index references passed as method arguments. References
-passed as arguments to control methods were dereferenced immediately (before
-control was passed to the called method). The references are now correctly
-passed directly to the called method. BZ 5389. Lin Ming
-
-Fixed a problem with CopyObject used in conjunction with the Index operator.
-The reference was incorrectly dereferenced before the copy. The reference is
-now correctly copied. BZ 5391. Lin Ming
-
-Fixed a problem with Control Method references within Package objects. These
-references are now correctly generated. This completes the package
-construction overhaul that began in version 20071019.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 78.8K Code, 17.2K Data, 96.0K Total
- Debug Version: 157.2K Code, 63.4K Data, 220.6K Total
- Current Release:
- Non-Debug Version: 79.0K Code, 17.2K Data, 96.2K Total
- Debug Version: 157.9K Code, 63.6K Data, 221.5K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-The AcpiExec utility now installs handlers for all of the predefined
-Operation Region types. New types supported are: PCI_Config, CMOS, and
-PCIBARTarget.
-
-Fixed a problem with the 64-bit version of AcpiExec where the extended (64-
-bit) address fields for the DSDT and FACS within the FADT were not being
-used, causing truncation of the upper 32-bits of these addresses. Lin Ming
-and Bob Moore
-
-----------------------------------------
-19 October 2007. Summary of changes for version 20071019:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem with the Alias operator when the target of the alias is a
-named ASL operator that opens a new scope -- Scope, Device, PowerResource,
-Processor, and ThermalZone. In these cases, any children of the original
-operator could not be accessed via the alias, potentially causing unexpected
-AE_NOT_FOUND exceptions. (BZ 9067)
-
-Fixed a problem with the Package operator where all named references were
-created as object references and left otherwise unresolved. According to the
-ACPI specification, a Package can only contain Data Objects or references to
-control methods. The implication is that named references to Data Objects
-(Integer, Buffer, String, Package, BufferField, Field) should be resolved
-immediately upon package creation. This is the approach taken with this
-change. References to all other named objects (Methods, Devices, Scopes,
-etc.) are all now properly created as reference objects. (BZ 5328)
-
-Reverted a change to Notify handling that was introduced in version
-20070508. This version changed the Notify handling from asynchronous to
-fully synchronous (Device driver Notify handling with respect to the Notify
-ASL operator). It was found that this change caused more problems than it
-solved and was removed by most users.
-
-Fixed a problem with the Increment and Decrement operators where the type of
-the target object could be unexpectedly and incorrectly changed. (BZ 353)
-Lin Ming.
-
-Fixed a problem with the Load and LoadTable operators where the table
-location within the namespace was ignored. Instead, the table was always
-loaded into the root or current scope. Lin Ming.
-
-Fixed a problem with the Load operator when loading a table from a buffer
-object. The input buffer was prematurely zeroed and/or deleted. (BZ 577)
-
-Fixed a problem with the Debug object where a store of a DdbHandle reference
-object to the Debug object could cause a fault.
-
-Added a table checksum verification for the Load operator, in the case where
-the load is from a buffer. (BZ 578).
-
-Implemented additional parameter validation for the LoadTable operator. The
-length of the input strings SignatureString, OemIdString, and OemTableId are
-now checked for maximum lengths. (BZ 582) Lin Ming.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 78.5K Code, 17.1K Data, 95.6K Total
- Debug Version: 156.7K Code, 63.2K Data, 219.9K Total

- Non-Debug Version: 78.8K Code, 17.2K Data, 96.0K Total
- Debug Version: 157.2K Code, 63.4K Data, 220.6K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a problem where if a single file was specified and the file did not
-exist, no error message was emitted. (Introduced with wildcard support in
-version 20070917.)
-
-----------------------------------------
-19 September 2007. Summary of changes for version 20070919:
-
-1) ACPI CA Core Subsystem:
-
-Designed and implemented new external interfaces to install and remove
-handlers for ACPI table-related events. Current events that are defined are
-LOAD and UNLOAD. These interfaces allow the host to track ACPI tables as
-they are dynamically loaded and unloaded. See AcpiInstallTableHandler and
-AcpiRemoveTableHandler. (Lin Ming and Bob Moore)
-
-Fixed a problem where the use of the AcpiGbl_AllMethodsSerialized flag
-(acpi_serialized option on Linux) could cause some systems to hang during
-initialization. (Bob Moore) BZ 8171
-
-Fixed a problem where objects of certain types (Device, ThermalZone,
-Processor, PowerResource) can be not found if they are declared and
-referenced from within the same control method (Lin Ming) BZ 341
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 78.3K Code, 17.0K Data, 95.3K Total
- Debug Version: 156.3K Code, 63.1K Data, 219.4K Total
- Current Release:
- Non-Debug Version: 78.5K Code, 17.1K Data, 95.6K Total
- Debug Version: 156.7K Code, 63.2K Data, 219.9K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Implemented support to allow multiple files to be compiled/disassembled in a
-single invocation. This includes command line wildcard support for both the
-Windows and Unix versions of the compiler. This feature simplifies the
-disassembly and compilation of multiple ACPI tables in a single directory.
-
-----------------------------------------
-08 May 2007. Summary of changes for version 20070508:
-
-1) ACPI CA Core Subsystem:
-
-Implemented a Microsoft compatibility design change for the handling of the
-Notify AML operator. Previously, notify handlers were dispatched and
-executed completely asynchronously in a deferred thread. The new design
-still executes the notify handlers in a different thread, but the original
-thread that executed the Notify() now waits at a synchronization point for
-the notify handler to complete. Some machines depend on a synchronous Notify
-operator in order to operate correctly.
-
-Implemented support to allow Package objects to be passed as method
-arguments to the external AcpiEvaluateObject interface. Previously, this
-would return the AE_NOT_IMPLEMENTED exception. This feature had not been
-implemented since there were no reserved control methods that required it
-until recently.
-
-Fixed a problem with the internal FADT conversion where ACPI 1.0 FADTs that
-contained invalid non-zero values in reserved fields could cause later
-failures because these fields have meaning in later revisions of the FADT.
-For incoming ACPI 1.0 FADTs, these fields are now always zeroed. (The fields
-are: Preferred_PM_Profile, PSTATE_CNT, CST_CNT, and IAPC_BOOT_FLAGS.)
-
-Fixed a problem where the Global Lock handle was not properly updated if a
-thread that acquired the Global Lock via executing AML code then attempted
-to acquire the lock via the AcpiAcquireGlobalLock interface. Reported by Joe
-Liu.
-
-Fixed a problem in AcpiEvDeleteGpeXrupt where the global interrupt list
-could be corrupted if the interrupt being removed was at the head of the
-list. Reported by Linn Crosetto.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.

-----------------------------------------
-20 March 2007. Summary of changes for version 20070320:
-
-1) ACPI CA Core Subsystem:
-
-Implemented a change to the order of interpretation and evaluation of AML
-operand objects within the AML interpreter. The interpreter now evaluates
-operands in the order that they appear in the AML stream (and the
-corresponding ASL code), instead of in the reverse order (after the entire
-operand list has been parsed). The previous behavior caused several subtle
-incompatibilities with the Microsoft AML interpreter as well as being
-somewhat non-intuitive. BZ 7871, local BZ 263. Valery Podrezov.
-
-Implemented a change to the ACPI Global Lock support. All interfaces to the
-global lock now allow the same thread to acquire the lock multiple times.
-This affects the AcpiAcquireGlobalLock external interface to the global lock
-as well as the internal use of the global lock to support AML fields -- a
-control method that is holding the global lock can now simultaneously access
-AML fields that require global lock protection. Previously, in both cases,
-this would have resulted in an AE_ALREADY_ACQUIRED exception. The change to
-AcpiAcquireGlobalLock is of special interest to drivers for the Embedded
-Controller. There is no change to the behavior of the AML Acquire operator,
-as this can already be used to acquire a mutex multiple times by the same
-thread. BZ 8066. With assistance from Alexey Starikovskiy.
-
-Fixed a problem where invalid objects could be referenced in the AML
-Interpreter after error conditions. During operand evaluation, ensure that
-the internal "Return Object" field is cleared on error and only valid
-pointers are stored there. Caused occasional access to deleted objects that
-resulted in "large reference count" warning messages. Valery Podrezov.
-
-Fixed a problem where an AE_STACK_OVERFLOW internal exception could occur on
-deeply nested control method invocations. BZ 7873, local BZ 487. Valery
-Podrezov.
-
-Fixed an internal problem with the handling of result objects on the
-interpreter result stack. BZ 7872. Valery Podrezov.
-
-Removed obsolete code that handled the case where AML_NAME_OP is the target
-of a reference (Reference.Opcode). This code was no longer necessary. BZ
-7874. Valery Podrezov.
-
-Removed obsolete ACPI_NO_INTEGER64_SUPPORT from two header files. This was a
-remnant from the previously discontinued 16-bit support.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.

-
-----------------------------------------
-26 January 2007. Summary of changes for version 20070126:
-
-1) ACPI CA Core Subsystem:
-
-Added the 2007 copyright to all module headers and signons. This affects
-virtually every file in the ACPICA core subsystem, the iASL compiler, and
-the utilities.
-
-Implemented a fix for an incorrect parameter passed to AcpiTbDeleteTable
-during a table load. A bad pointer was passed in the case where the DSDT is
-overridden, causing a fault in this case.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has

-
-----------------------------------------
-15 December 2006. Summary of changes for version 20061215:
-
-1) ACPI CA Core Subsystem:
-
-Support for 16-bit ACPICA has been completely removed since it is no longer
-necessary and it clutters the code. All 16-bit macros, types, and
-conditional compiles have been removed, cleaning up and simplifying the code
-across the entire subsystem. DOS support is no longer needed since the
-bootable Linux firmware kit is now available.
-
-The handler for the Global Lock is now removed during AcpiTerminate to
-enable a clean subsystem restart, via the implementation of the
-AcpiEvRemoveGlobalLockHandler function. (With assistance from Joel Bretz,
-HP)
-
-Implemented enhancements to the multithreading support within the debugger
-to enable improved multithreading debugging and evaluation of the subsystem.
-(Valery Podrezov)
-
-Debugger: Enhanced the Statistics/Memory command to emit the total (maximum)
-memory used during the execution, as well as the maximum memory consumed by
-each of the various object types. (Valery Podrezov)
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 77.9K Code, 17.0K Data, 94.9K Total
- Debug Version: 155.2K Code, 63.1K Data, 218.3K Total
- Current Release:
- Non-Debug Version: 78.0K Code, 17.1K Data, 95.1K Total
- Debug Version: 155.8K Code, 63.3K Data, 219.1K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-AcpiExec: Implemented a new option (-m) to display full memory use
-statistics upon subsystem/program termination. (Valery Podrezov)
-
-----------------------------------------
-09 November 2006. Summary of changes for version 20061109:
-
-1) ACPI CA Core Subsystem:
-
-Optimized the Load ASL operator in the case where the source operand is an
-operation region. Simply map the operation region memory, instead of
-performing a bytewise read. (Region must be of type SystemMemory, see
-below.)
-
-Fixed the Load ASL operator for the case where the source operand is a
-region field. A buffer object is also allowed as the source operand. BZ 480
-
-Fixed a problem where the Load ASL operator allowed the source operand to be
-an operation region of any type. It is now restricted to regions of type
-SystemMemory, as per the ACPI specification. BZ 481
-
-Additional cleanup and optimizations for the new Table Manager code.
-
-AcpiEnable will now fail if all of the required ACPI tables are not loaded
-(FADT, FACS, DSDT). BZ 477
-
-Added #pragma pack(8/4) to acobject.h to ensure that the structures in this
-header are always compiled as aligned. The ACPI_OPERAND_OBJECT has been
-manually optimized to be aligned and will not work if it is byte-packed.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 78.1K Code, 17.1K Data, 95.2K Total
- Debug Version: 155.4K Code, 63.1K Data, 218.5K Total

- Non-Debug Version: 77.9K Code, 17.0K Data, 94.9K Total
- Debug Version: 155.2K Code, 63.1K Data, 218.3K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-Fixed a problem where the presence of the _OSI predefined control method
-within complex expressions could cause an internal compiler error.
-
-AcpiExec: Implemented full region support for multiple address spaces.
-SpaceId is now part of the REGION object. BZ 429
-
-----------------------------------------
-11 October 2006. Summary of changes for version 20061011:
-
-1) ACPI CA Core Subsystem:
-
-Completed an AML interpreter performance enhancement for control method
-execution. Previously a 2-pass parse/execution, control methods are now
-completely parsed and executed in a single pass. This improves overall
-interpreter performance by ~25%, reduces code size, and reduces CPU stack
-use. (Valery Podrezov + interpreter changes in version 20051202 that
-eliminated namespace loading during the pass one parse.)
-
-Implemented _CID support for PCI Root Bridge detection. If the _HID does not
-match the predefined PCI Root Bridge IDs, the _CID list (if present) is now
-obtained and also checked for an ID match.
-
-Implemented additional support for the PCI _ADR execution: upsearch until a
-device scope is found before executing _ADR. This allows PCI_Config
-operation regions to be declared locally within control methods underneath
-PCI device objects.
-
-Fixed a problem with a possible race condition between threads executing
-AcpiWalkNamespace and the AML interpreter. This condition was removed by
-modifying AcpiWalkNamespace to (by default) ignore all temporary namespace
-entries created during any concurrent control method execution. An
-additional namespace race condition is known to exist between
-AcpiWalkNamespace and the Load/Unload ASL operators and is still under
-investigation.
-
-Restructured the AML ParseLoop function, breaking it into several
-subfunctions in order to reduce CPU stack use and improve maintainability.
-(Mikhail Kouzmich)
-
-AcpiGetHandle: Fix for parameter validation to detect invalid combinations
-of prefix handle and pathname. BZ 478
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 77.9K Code, 17.1K Data, 95.0K Total
- Debug Version: 154.6K Code, 63.0K Data, 217.6K Total
- Current Release:
- Non-Debug Version: 78.1K Code, 17.1K Data, 95.2K Total
- Debug Version: 155.4K Code, 63.1K Data, 218.5K Total
-
-2) iASL Compiler/Disassembler and Tools:
-
-Ported the -g option (get local ACPI tables) to the new ACPICA Table Manager
-to restore original behavior.
-
-----------------------------------------
-27 September 2006. Summary of changes for version 20060927:
-
-1) ACPI CA Core Subsystem:
-
-Removed the "Flags" parameter from AcpiGetRegister and AcpiSetRegister.
-These functions now use a spinlock for mutual exclusion and the interrupt
-level indication flag is not needed.
-
-Fixed a problem with the Global Lock where the lock could appear to be
-obtained before it is actually obtained. The global lock semaphore was
-inadvertently created with one unit instead of zero units. (BZ 464) Fiodor
-Suietov.
-
-Fixed a possible memory leak and fault in AcpiExResolveObjectToValue during
-a read from a buffer or region field. (BZ 458) Fiodor Suietov.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 77.9K Code, 17.1K Data, 95.0K Total
- Debug Version: 154.7K Code, 63.0K Data, 217.7K Total
- Current Release:
- Non-Debug Version: 77.9K Code, 17.1K Data, 95.0K Total
- Debug Version: 154.6K Code, 63.0K Data, 217.6K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-Fixed a compilation problem with the pre-defined Resource Descriptor field
-names where an "object does not exist" error could be incorrectly generated
-if the parent ResourceTemplate pathname places the template within a
-different namespace scope than the current scope. (BZ 7212)
-
-Fixed a problem where the compiler could hang after syntax errors detected
-in an ElseIf construct. (BZ 453)
-
-Fixed a problem with the AmlFilename parameter to the DefinitionBlock()
-operator. An incorrect output filename was produced when this parameter was
-a null string (""). Now, the original input filename is used as the AML
-output filename, with an ".aml" extension.
-
-Implemented a generic batch command mode for the AcpiExec utility (execute
-any AML debugger command) (Valery Podrezov).
-
-----------------------------------------
-12 September 2006. Summary of changes for version 20060912:
-
-1) ACPI CA Core Subsystem:
-
-Enhanced the implementation of the "serialized mode" of the interpreter
-(enabled via the AcpiGbl_AllMethodsSerialized flag.) When this mode is
-specified, instead of creating a serialization semaphore per control method,
-the interpreter lock is simply no longer released before a blocking
-operation during control method execution. This effectively makes the AML
-Interpreter single-threaded. The overhead of a semaphore per-method is
-eliminated.
-
-Fixed a regression where an error was no longer emitted if a control method
-attempts to create 2 objects of the same name. This once again returns
-AE_ALREADY_EXISTS. When this exception occurs, it invokes the mechanism that
-will dynamically serialize the control method to possible prevent future
-errors. (BZ 440)
-
-Integrated a fix for a problem with PCI Express HID detection in the PCI
-Config Space setup procedure. (BZ 7145)
-
-Moved all FADT-related functions to a new file, tbfadt.c. Eliminated the
-AcpiHwInitialize function - the FADT registers are now validated when the
-table is loaded.
-
-Added two new warnings during FADT verification - 1) if the FADT is larger
-than the largest known FADT version, and 2) if there is a mismatch between a
-32-bit block address and the 64-bit X counterpart (when both are non-zero.)
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 77.9K Code, 16.7K Data, 94.6K Total
- Debug Version: 154.9K Code, 62.6K Data, 217.5K Total
- Current Release:
- Non-Debug Version: 77.9K Code, 17.1K Data, 95.0K Total
- Debug Version: 154.7K Code, 63.0K Data, 217.7K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-Fixed a problem with the implementation of the Switch() operator where the
-temporary variable was declared too close to the actual Switch, instead of
-at method level. This could cause a problem if the Switch() operator is
-within a while loop, causing an error on the second iteration. (BZ 460)
-
-Disassembler - fix for error emitted for unknown type for target of scope
-operator. Now, ignore it and continue.
-
-Disassembly of an FADT now verifies the input FADT and reports any errors
-found. Fix for proper disassembly of full-sized (ACPI 2.0) FADTs.
-
-Disassembly of raw data buffers with byte initialization data now prefixes
-each output line with the current buffer offset.
-
-Disassembly of ASF! table now includes all variable-length data fields at
-the end of some of the subtables.
-
-The disassembler now emits a comment if a buffer appears to be a
-ResourceTemplate, but cannot be disassembled as such because the EndTag does
-not appear at the very end of the buffer.
-
-AcpiExec - Added the "-t" command line option to enable the serialized mode
-of the AML interpreter.
-
-----------------------------------------
-31 August 2006. Summary of changes for version 20060831:
-
-1) ACPI CA Core Subsystem:
-
-Miscellaneous fixes for the Table Manager:
-- Correctly initialize internal common FADT for all 64-bit "X" fields
-- Fixed a couple table mapping issues during table load
-- Fixed a couple alignment issues for IA64
-- Initialize input array to zero in AcpiInitializeTables
-- Additional parameter validation for AcpiGetTable, AcpiGetTableHeader,
-AcpiGetTableByIndex
-
-Change for GPE support: when a "wake" GPE is received, all wake GPEs are now
-immediately disabled to prevent the waking GPE from firing again and to
-prevent other wake GPEs from interrupting the wake process.
-
-Added the AcpiGpeCount global that tracks the number of processed GPEs, to
-be used for debugging systems with a large number of ACPI interrupts.
-
-Implemented support for the "DMAR" ACPI table (DMA Redirection Table) in
-both the ACPICA headers and the disassembler.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.

- Debug Version: 154.9K Code, 62.6K Data, 217.5K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-Disassembler support for the DMAR ACPI table.
-
-----------------------------------------
-23 August 2006. Summary of changes for version 20060823:
-
-1) ACPI CA Core Subsystem:
-
-The Table Manager component has been completely redesigned and
-reimplemented. The new design is much simpler, and reduces the overall code
-and data size of the kernel-resident ACPICA by approximately 5%. Also, it is
-now possible to obtain the ACPI tables very early during kernel
-initialization, even before dynamic memory management is initialized.
-(Alexey Starikovskiy, Fiodor Suietov, Bob Moore)
-
-Obsolete ACPICA interfaces:
-
-- AcpiGetFirmwareTable: Use AcpiGetTable instead (works at early kernel init
-time).
-- AcpiLoadTable: Not needed.
-- AcpiUnloadTable: Not needed.
-
-New ACPICA interfaces:
-
-- AcpiInitializeTables: Must be called before the table manager can be used.
-- AcpiReallocateRootTable: Used to transfer the root table to dynamically
-allocated memory after it becomes available.
-- AcpiGetTableByIndex: Allows the host to easily enumerate all ACPI tables
-in the RSDT/XSDT.
-
-Other ACPICA changes:
-
-- AcpiGetTableHeader returns the actual mapped table header, not a copy. Use
-AcpiOsUnmapMemory to free this mapping.
-- AcpiGetTable returns the actual mapped table. The mapping is managed
-internally and must not be deleted by the caller. Use of this interface
-causes no additional dynamic memory allocation.
-- AcpiFindRootPointer: Support for physical addressing has been eliminated,
-it appeared to be unused.
-- The interface to AcpiOsMapMemory has changed to be consistent with the
-other allocation interfaces.
-- The interface to AcpiOsGetRootPointer has changed to eliminate unnecessary
-parameters.
-- ACPI_PHYSICAL_ADDRESS is now 32 bits on 32-bit platforms, 64 bits on 64-
-bit platforms. Was previously 64 bits on all platforms.
-- The interface to the ACPI Global Lock acquire/release macros have changed
-slightly since ACPICA no longer keeps a local copy of the FACS with a
-constructed pointer to the actual global lock.
-
-Porting to the new table manager:
-
-- AcpiInitializeTables: Must be called once, and can be called anytime
-during the OS initialization process. It allows the host to specify an area
-of memory to be used to store the internal version of the RSDT/XSDT (root
-table). This allows the host to access ACPI tables before memory management
-is initialized and running.
-- AcpiReallocateRootTable: Can be called after memory management is running
-to copy the root table to a dynamically allocated array, freeing up the
-scratch memory specified in the call to AcpiInitializeTables.
-- AcpiSubsystemInitialize: This existing interface is independent of the
-Table Manager, and does not have to be called before the Table Manager can
-be used, it only must be called before the rest of ACPICA can be used.
-- ACPI Tables: Some changes have been made to the names and structure of the
-actbl.h and actbl1.h header files and may require changes to existing code.
-For example, bitfields have been completely removed because of their lack of
-portability across C compilers.
-- Update interfaces to the Global Lock acquire/release macros if local
-versions are used. (see acwin.h)
-
-Obsolete files: tbconvrt.c, tbget.c, tbgetall.c, tbrsdt.c
-
-New files: tbfind.c
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.

-
-----------------------------------------
-21 July 2006. Summary of changes for version 20060721:
-
-1) ACPI CA Core Subsystem:
-
-The full source code for the ASL test suite used to validate the iASL
-compiler and the ACPICA core subsystem is being released with the ACPICA
-source for the first time. The source is contained in a separate package and
-consists of over 1100 files that exercise all ASL/AML operators. The package
-should appear on the Intel/ACPI web site shortly. (Valery Podrezov, Fiodor
-Suietov)
-
-Completed a new design and implementation for support of the ACPI Global
-Lock. On the OS side, the global lock is now treated as a standard AML
-mutex. Previously, multiple OS threads could "acquire" the global lock
-simultaneously. However, this could cause the BIOS to be starved out of the
-lock - especially in cases such as the Embedded Controller driver where
-there is a tight coupling between the OS and the BIOS.
-
-Implemented an optimization for the ACPI Global Lock interrupt mechanism.
-The Global Lock interrupt handler no longer queues the execution of a
-separate thread to signal the global lock semaphore. Instead, the semaphore
-is signaled directly from the interrupt handler.
-
-Implemented support within the AML interpreter for package objects that
-contain a larger AML length (package list length) than the package element
-count. In this case, the length of the package is truncated to match the
-package element count. Some BIOS code apparently modifies the package length
-on the fly, and this change supports this behavior. Provides compatibility
-with the MS AML interpreter. (With assistance from Fiodor Suietov)
-
-Implemented a temporary fix for the BankValue parameter of a Bank Field to
-support all constant values, now including the Zero and One opcodes.
-Evaluation of this parameter must eventually be converted to a full TermArg
-evaluation. A not-implemented error is now returned (temporarily) for non-
-constant values for this parameter.
-
-Fixed problem reports (Fiodor Suietov) integrated:
-- Fix for premature object deletion after CopyObject on Operation Region (BZ
-350)
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.

-
-----------------------------------------
-07 July 2006. Summary of changes for version 20060707:
-
-1) ACPI CA Core Subsystem:
-
-Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to support C compilers
-that do not allow the initialization of address pointers within packed
-structures - even though the hardware itself may support misaligned
-transfers. Some of the debug data structures are packed by default to
-minimize size.
-
-Added an error message for the case where AcpiOsGetThreadId() returns zero.
-A non-zero value is required by the core ACPICA code to ensure the proper
-operation of AML mutexes and recursive control methods.
-
-The DSDT is now the only ACPI table that determines whether the AML
-interpreter is in 32-bit or 64-bit mode. Not really a functional change, but
-the hooks for per-table 32/64 switching have been removed from the code. A
-clarification to the ACPI specification is forthcoming in ACPI 3.0B.
-
-Fixed a possible leak of an OwnerID in the error path of
-AcpiTbInitTableDescriptor (tbinstal.c), and migrated all table OwnerID
-deletion to a single place in AcpiTbUninstallTable to correct possible leaks
-when using the AcpiTbDeleteTablesByType interface (with assistance from
-Lance Ortiz.)
-
-Fixed a problem with Serialized control methods where the semaphore
-associated with the method could be over-signaled after multiple method
-invocations.
-
-Fixed two issues with the locking of the internal namespace data structure.
-Both the Unload() operator and AcpiUnloadTable interface now lock the
-namespace during the namespace deletion associated with the table unload
-(with assistance from Linn Crosetto.)
-
-Fixed problem reports (Valery Podrezov) integrated:
-- Eliminate unnecessary memory allocation for CreateXxxxField (BZ 5426)
-

-
-----------------------------------------
-23 June 2006. Summary of changes for version 20060623:
-
-1) ACPI CA Core Subsystem:
-
-Implemented a new ACPI_SPINLOCK type for the OSL lock interfaces. This
-allows the type to be customized to the host OS for improved efficiency
-(since a spinlock is usually a very small object.)
-
-Implemented support for "ignored" bits in the ACPI registers. According to
-the ACPI specification, these bits should be preserved when writing the
-registers via a read/modify/write cycle. There are 3 bits preserved in this
-manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9], and PM1_STATUS[11].
-
-Implemented the initial deployment of new OSL mutex interfaces. Since some
-host operating systems have separate mutex and semaphore objects, this
-feature was requested. The base code now uses mutexes (and the new mutex
-interfaces) wherever a binary semaphore was used previously. However, for
-the current release, the mutex interfaces are defined as macros to map them
-to the existing semaphore interfaces. Therefore, no OSL changes are required
-at this time. (See acpiosxf.h)
-
-Fixed several problems with the support for the control method SyncLevel
-parameter. The SyncLevel now works according to the ACPI specification and
-in concert with the Mutex SyncLevel parameter, since the current SyncLevel
-is a property of the executing thread. Mutual exclusion for control methods
-is now implemented with a mutex instead of a semaphore.
-
-Fixed three instances of the use of the C shift operator in the bitfield
-support code (exfldio.c) to avoid the use of a shift value larger than the
-target data width. The behavior of C compilers is undefined in this case and
-can cause unpredictable results, and therefore the case must be detected and
-avoided. (Fiodor Suietov)
-
-Added an info message whenever an SSDT or OEM table is loaded dynamically
-via the Load() or LoadTable() ASL operators. This should improve debugging
-capability since it will show exactly what tables have been loaded (beyond
-the tables present in the RSDT/XSDT.)
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.

-
-----------------------------------------
-08 June 2006. Summary of changes for version 20060608:
-
-1) ACPI CA Core Subsystem:
-
-Converted the locking mutex used for the ACPI hardware to a spinlock. This
-change should eliminate all problems caused by attempting to acquire a
-semaphore at interrupt level, and it means that all ACPICA external
-interfaces that directly access the ACPI hardware can be safely called from
-interrupt level. OSL code that implements the semaphore interfaces should be
-able to eliminate any workarounds for being called at interrupt level.
-
-Fixed a regression introduced in 20060526 where the ACPI device
-initialization could be prematurely aborted with an AE_NOT_FOUND if a device
-did not have an optional _INI method.
-
-Fixed an IndexField issue where a write to the Data Register should be
-limited in size to the AccessSize (width) of the IndexField itself. (BZ 433,
-Fiodor Suietov)
-
-Fixed problem reports (Valery Podrezov) integrated:
-- Allow store of ThermalZone objects to Debug object (BZ 5369/5370)
-
-Fixed problem reports (Fiodor Suietov) integrated:
-- AcpiGetTableHeader doesn't handle multiple instances correctly (BZ 364)
-
-Removed four global mutexes that were obsolete and were no longer being
-used.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 80.0K Code, 17.7K Data, 97.7K Total
- Debug Version: 160.3K Code, 64.9K Data, 225.2K Total

- Non-Debug Version: 80.0K Code, 17.6K Data, 97.6K Total
- Debug Version: 160.2K Code, 64.7K Data, 224.9K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-Fixed a fault when using -g option (get tables from registry) on Windows
-machines.
-
-Fixed problem reports integrated:
-- Generate error if CreateField NumBits parameter is zero. (BZ 405)
-- Fault if Offset/Length in Field unit is very large (BZ 432, Fiodor
-Suietov)
-- Global table revision override (-r) is ignored (BZ 413)
-
-----------------------------------------
-26 May 2006. Summary of changes for version 20060526:
-
-1) ACPI CA Core Subsystem:
-
-Restructured, flattened, and simplified the internal interfaces for
-namespace object evaluation - resulting in smaller code, less CPU stack use,
-and fewer interfaces. (With assistance from Mikhail Kouzmich)
-
-Fixed a problem with the CopyObject operator where the first parameter was
-not typed correctly for the parser, interpreter, compiler, and disassembler.
-Caused various errors and unexpected behavior.
-
-Fixed a problem where a ShiftLeft or ShiftRight of more than 64 bits
-produced incorrect results with some C compilers. Since the behavior of C
-compilers when the shift value is larger than the datatype width is
-apparently not well defined, the interpreter now detects this condition and
-simply returns zero as expected in all such cases. (BZ 395)
-
-Fixed problem reports (Valery Podrezov) integrated:
-- Update String-to-Integer conversion to match ACPI 3.0A spec (BZ 5329)
-- Allow interpreter to handle nested method declarations (BZ 5361)
-
-Fixed problem reports (Fiodor Suietov) integrated:
-- AcpiTerminate doesn't free debug memory allocation list objects (BZ 355)
-- After Core Subsystem shutdown, AcpiSubsystemStatus returns AE_OK (BZ 356)
-- AcpiOsUnmapMemory for RSDP can be invoked inconsistently (BZ 357)
-- Resource Manager should return AE_TYPE for non-device objects (BZ 358)
-- Incomplete cleanup branch in AcpiNsEvaluateRelative (BZ 359)
-- Use AcpiOsFree instead of ACPI_FREE in AcpiRsSetSrsMethodData (BZ 360)
-- Incomplete cleanup branch in AcpiPsParseAml (BZ 361)
-- Incomplete cleanup branch in AcpiDsDeleteWalkState (BZ 362)
-- AcpiGetTableHeader returns AE_NO_ACPI_TABLES until DSDT is loaded (BZ 365)
-- Status of the Global Initialization Handler call not used (BZ 366)
-- Incorrect object parameter to Global Initialization Handler (BZ 367)
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 79.8K Code, 17.7K Data, 97.5K Total
- Debug Version: 160.5K Code, 65.1K Data, 225.6K Total
- Current Release:
- Non-Debug Version: 80.0K Code, 17.7K Data, 97.7K Total
- Debug Version: 160.3K Code, 64.9K Data, 225.2K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-Modified the parser to allow the names IO, DMA, and IRQ to be used as
-namespace identifiers with no collision with existing resource descriptor
-macro names. This provides compatibility with other ASL compilers and is
-most useful for disassembly/recompilation of existing tables without parse
-errors. (With assistance from Thomas Renninger)
-
-Disassembler: fixed an incorrect disassembly problem with the
-DataTableRegion and CopyObject operators. Fixed a possible fault during
-disassembly of some Alias operators.
-
-----------------------------------------
-12 May 2006. Summary of changes for version 20060512:
-
-1) ACPI CA Core Subsystem:
-
-Replaced the AcpiOsQueueForExecution interface with a new interface named
-AcpiOsExecute. The major difference is that the new interface does not have
-a Priority parameter, this appeared to be useless and has been replaced by a
-Type parameter. The Type tells the host what type of execution is being
-requested, such as global lock handler, notify handler, GPE handler, etc.
-This allows the host to queue and execute the request as appropriate for the
-request type, possibly using different work queues and different priorities
-for the various request types. This enables fixes for multithreading
-deadlock problems such as BZ #5534, and will require changes to all existing
-OS interface layers. (Alexey Starikovskiy and Bob Moore)
-
-Fixed a possible memory leak associated with the support for the so-called
-"implicit return" ACPI extension. Reported by FreeBSD, BZ #6514. (Fiodor
-Suietov)
-
-Fixed a problem with the Load() operator where a table load from an
-operation region could overwrite an internal table buffer by up to 7 bytes
-and cause alignment faults on IPF systems. (With assistance from Luming Yu)
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 79.7K Code, 17.7K Data, 97.4K Total
- Debug Version: 160.1K Code, 65.2K Data, 225.3K Total
- Current Release:
- Non-Debug Version: 79.8K Code, 17.7K Data, 97.5K Total
- Debug Version: 160.5K Code, 65.1K Data, 225.6K Total
-
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-Disassembler: Implemented support to cross reference the internal namespace
-and automatically generate ASL External() statements for symbols not defined
-within the current table being disassembled. This will simplify the
-disassembly and recompilation of interdependent tables such as SSDTs since
-these statements will no longer have to be added manually.
-
-Disassembler: Implemented experimental support to automatically detect
-invocations of external control methods and generate appropriate External()
-statements. This is problematic because the AML cannot be correctly parsed
-until the number of arguments for each control method is known. Currently,
-standalone method invocations and invocations as the source operand of a
-Store() statement are supported.
-
-Disassembler: Implemented support for the ASL pseudo-operators LNotEqual,
-LLessEqual, and LGreaterEqual. Previously disassembled as LNot(LEqual()),
-LNot(LGreater()), and LNot(LLess()), this makes the disassembled ASL code
-more readable and likely closer to the original ASL source.
-
-----------------------------------------
-21 April 2006. Summary of changes for version 20060421:
-
-1) ACPI CA Core Subsystem:
-
-Removed a device initialization optimization introduced in 20051216 where
-the _STA method was not run unless an _INI was also present for the same
-device. This optimization could cause problems because it could allow _INI
-methods to be run within a not-present device subtree. (If a not-present
-device had no _INI, _STA would not be run, the not-present status would not
-be discovered, and the children of the device would be incorrectly
-traversed.)
-
-Implemented a new _STA optimization where namespace subtrees that do not
-contain _INI are identified and ignored during device initialization.
-Selectively running _STA can significantly improve boot time on large
-machines (with assistance from Len Brown.)
-
-Implemented support for the device initialization case where the returned
-_STA flags indicate a device not-present but functioning. In this case, _INI
-is not run, but the device children are examined for presence, as per the
-ACPI specification.
-
-Implemented an additional change to the IndexField support in order to
-conform to MS behavior. The value written to the Index Register is not
-simply a byte offset, it is a byte offset in units of the access width of
-the parent Index Field. (Fiodor Suietov)
-
-Defined and deployed a new OSL interface, AcpiOsValidateAddress. This
-interface is called during the creation of all AML operation regions, and
-allows the host OS to exert control over what addresses it will allow the
-AML code to access. Operation Regions whose addresses are disallowed will
-cause a runtime exception when they are actually accessed (will not affect
-or abort table loading.) See oswinxf or osunixxf for an example
-implementation.
-
-Defined and deployed a new OSL interface, AcpiOsValidateInterface. This
-interface allows the host OS to match the various "optional"
-interface/behavior strings for the _OSI predefined control method as
-appropriate (with assistance from Bjorn Helgaas.) See oswinxf or osunixxf
-for an example implementation.
-
-Restructured and corrected various problems in the exception handling code
-paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod
-(with assistance from Takayoshi Kochi.)
-
-Modified the Linux source converter to ignore quoted string literals while
-converting identifiers from mixed to lower case. This will correct problems
-with the disassembler and other areas where such strings must not be
-modified.
-
-The ACPI_FUNCTION_* macros no longer require quotes around the function
-name. This allows the Linux source converter to convert the names, now that
-the converter ignores quoted strings.
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
-
- Non-Debug Version: 81.1K Code, 17.7K Data, 98.8K Total
- Debug Version: 158.9K Code, 64.9K Data, 223.8K Total
- Current Release:
- Non-Debug Version: 79.7K Code, 17.7K Data, 97.4K Total
- Debug Version: 160.1K Code, 65.2K Data, 225.3K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-Implemented 3 new warnings for iASL, and implemented multiple warning levels
-(w2 flag).
-
-1) Ignored timeouts: If the TimeoutValue parameter to Wait or Acquire is not
-WAIT_FOREVER (0xFFFF) and the code does not examine the return value to
-check for the possible timeout, a warning is issued.
-
-2) Useless operators: If an ASL operator does not specify an optional target
-operand and it also does not use the function return value from the
-operator, a warning is issued since the operator effectively does nothing.
-
-3) Unreferenced objects: If a namespace object is created, but never
-referenced, a warning is issued. This is a warning level 2 since there are
-cases where this is ok, such as when a secondary table is loaded that uses
-the unreferenced objects. Even so, care is taken to only flag objects that
-don't look like they will ever be used. For example, the reserved methods
-(starting with an underscore) are usually not referenced because it is
-expected that the OS will invoke them.
-
-----------------------------------------
-31 March 2006. Summary of changes for version 20060331:
-
-1) ACPI CA Core Subsystem:
-
-Implemented header file support for the following additional ACPI tables:
-ASF!, BOOT, CPEP, DBGP, MCFG, SPCR, SPMI, TCPA, and WDRT. With this support,
-all current and known ACPI tables are now defined in the ACPICA headers and
-are available for use by device drivers and other software.
-
-Implemented support to allow tables that contain ACPI names with invalid
-characters to be loaded. Previously, this would cause the table load to
-fail, but since there are several known cases of such tables on existing
-machines, this change was made to enable ACPI support for them. Also, this
-matches the behavior of the Microsoft ACPI implementation.
-
-Fixed a couple regressions introduced during the memory optimization in the
-20060317 release. The namespace node definition required additional
-reorganization and an internal datatype that had been changed to 8-bit was
-restored to 32-bit. (Valery Podrezov)
-
-Fixed a problem where a null pointer passed to AcpiUtDeleteGenericState
-could be passed through to AcpiOsReleaseObject which is unexpected. Such
-null pointers are now trapped and ignored, matching the behavior of the
-previous implementation before the deployment of AcpiOsReleaseObject.
-(Valery Podrezov, Fiodor Suietov)
-
-Fixed a memory mapping leak during the deletion of a SystemMemory operation
-region where a cached memory mapping was not deleted. This became a
-noticeable problem for operation regions that are defined within frequently
-used control methods. (Dana Meyers)
-
-Reorganized the ACPI table header files into two main files: one for the
-ACPI tables consumed by the ACPICA core, and another for the miscellaneous
-ACPI tables that are consumed by the drivers and other software. The various
-FADT definitions were merged into one common section and three different
-tables (ACPI 1.0, 1.0+, and 2.0)
-
-Example Code and Data Size: These are the sizes for the OS-independent
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The
-debug version of the code includes the debug output trace mechanism and has
-a much larger code and data size.
-
- Previous Release:
- Non-Debug Version: 80.9K Code, 17.7K Data, 98.6K Total
- Debug Version: 158.7K Code, 64.8K Data, 223.5K Total
- Current Release:
- Non-Debug Version: 81.1K Code, 17.7K Data, 98.8K Total
- Debug Version: 158.9K Code, 64.9K Data, 223.8K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-Disassembler: Implemented support to decode and format all non-AML ACPI
-tables (tables other than DSDTs and SSDTs.) This includes the new tables
-added to the ACPICA headers, therefore all current and known ACPI tables are
-supported.
-
-Disassembler: The change to allow ACPI names with invalid characters also
-enables the disassembly of such tables. Invalid characters within names are
-changed to '*' to make the name printable; the iASL compiler will still
-generate an error for such names, however, since this is an invalid ACPI
-character.
-
-Implemented an option for AcpiXtract (-a) to extract all tables found in the
-input file. The default invocation extracts only the DSDTs and SSDTs.
-
-Fixed a couple of gcc generation issues for iASL and AcpiExec and added a
-makefile for the AcpiXtract utility.
-
-----------------------------------------
-17 March 2006. Summary of changes for version 20060317:
-
-1) ACPI CA Core Subsystem:
-
-Implemented the use of a cache object for all internal namespace nodes.
-Since there are about 1000 static nodes in a typical system, this will
-decrease memory use for cache implementations that minimize per-allocation
-overhead (such as a slab allocator.)
-
-Removed the reference count mechanism for internal namespace nodes, since it
-was deemed unnecessary. This reduces the size of each namespace node by
-about 5%-10% on all platforms. Nodes are now 20 bytes for the 32-bit case,
-and 32 bytes for the 64-bit case.
-
-Optimized several internal data structures to reduce object size on 64-bit
-platforms by packing data within the 64-bit alignment. This includes the
-frequently used ACPI_OPERAND_OBJECT, of which there can be ~1000 static
-instances corresponding to the namespace objects.
-
-Added two new strings for the predefined _OSI method: "Windows 2001.1 SP1"
-and "Windows 2006".
-
-Split the allocation tracking mechanism out to a separate file, from
-utalloc.c to uttrack.c. This mechanism appears to be only useful for
-application-level code. Kernels may wish to not include uttrack.c in
-distributions.
-
-Removed all remnants of the obsolete ACPI_REPORT_* macros and the associated
-code. (These macros have been replaced by the ACPI_ERROR and ACPI_WARNING
-macros.)
-
-Code and Data Size: These are the sizes for the acpica.lib produced by the
-Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI
-driver or OSPM code. The debug version of the code includes the debug output
-trace mechanism and has a much larger code and data size. Note that these
-values will vary depending on the efficiency of the compiler and the
-compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total
- Debug Version: 161.6K Code, 65.7K Data, 227.3K Total
- Current Release:
- Non-Debug Version: 80.9K Code, 17.7K Data, 98.6K Total
- Debug Version: 158.7K Code, 64.8K Data, 223.5K Total
-
-
-2) iASL Compiler/Disassembler and Tools:
-
-Implemented an ANSI C version of the acpixtract utility. This version will
-automatically extract the DSDT and all SSDTs from the input acpidump text
-file and dump the binary output to separate files. It can also display a
-summary of the input file including the headers for each table found and
-will extract any single ACPI table, with any signature. (See
-source/tools/acpixtract)
-
-----------------------------------------
-10 March 2006. Summary of changes for version 20060310:
-
-1) ACPI CA Core Subsystem:
-
-Tagged all external interfaces to the subsystem with the new
-ACPI_EXPORT_SYMBOL macro. This macro can be defined as necessary to assist
-kernel integration. For Linux, the macro resolves to the EXPORT_SYMBOL
-macro. The default definition is NULL.
-
-Added the ACPI_THREAD_ID type for the return value from AcpiOsGetThreadId.
-This allows the host to define this as necessary to simplify kernel
-integration. The default definition is ACPI_NATIVE_UINT.
-
-Fixed two interpreter problems related to error processing, the deletion of
-objects, and placing invalid pointers onto the internal operator result
-stack. BZ 6028, 6151 (Valery Podrezov)
-
-Increased the reference count threshold where a warning is emitted for large
-reference counts in order to eliminate unnecessary warnings on systems with
-large namespaces (especially 64-bit.) Increased the value from 0x400 to
-0x800.
-
-Due to universal disagreement as to the meaning of the 'c' in the calloc()
-function, the ACPI_MEM_CALLOCATE macro has been renamed to
-ACPI_ALLOCATE_ZEROED so that the purpose of the interface is 'clear'.
-ACPI_MEM_ALLOCATE and ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and
-ACPI_FREE.
-
-Code and Data Size: These are the sizes for the acpica.lib produced by the
-Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI
-driver or OSPM code. The debug version of the code includes the debug output
-trace mechanism and has a much larger code and data size. Note that these
-values will vary depending on the efficiency of the compiler and the
-compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 81.0K Code, 17.8K Data, 98.8K Total
- Debug Version: 161.4K Code, 65.7K Data, 227.1K Total
- Current Release:
- Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total
- Debug Version: 161.6K Code, 65.7K Data, 227.3K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Disassembler: implemented support for symbolic resource descriptor
-references. If a CreateXxxxField operator references a fixed offset within a
-resource descriptor, a name is assigned to the descriptor and the offset is
-translated to the appropriate resource tag and pathname. The addition of
-this support brings the disassembled code very close to the original ASL
-source code and helps eliminate run-time errors when the disassembled code
-is modified (and recompiled) in such a way as to invalidate the original
-fixed offsets.
-
-Implemented support for a Descriptor Name as the last parameter to the ASL
-Register() macro. This parameter was inadvertently left out of the ACPI
-specification, and will be added for ACPI 3.0b.
-
-Fixed a problem where the use of the "_OSI" string (versus the full path
-"\_OSI") caused an internal compiler error. ("No back ptr to op")
-
-Fixed a problem with the error message that occurs when an invalid string is
-used for a _HID object (such as one with an embedded asterisk: "*PNP010A".)
-The correct message is now displayed.
-
-----------------------------------------
-17 February 2006. Summary of changes for version 20060217:
-
-1) ACPI CA Core Subsystem:
-
-Implemented a change to the IndexField support to match the behavior of the
-Microsoft AML interpreter. The value written to the Index register is now a
-byte offset, no longer an index based upon the width of the Data register.
-This should fix IndexField problems seen on some machines where the Data
-register is not exactly one byte wide. The ACPI specification will be
-clarified on this point.
-
-Fixed a problem where several resource descriptor types could overrun the
-internal descriptor buffer due to size miscalculation: VendorShort,
-VendorLong, and Interrupt. This was noticed on IA64 machines, but could
-affect all platforms.
-
-Fixed a problem where individual resource descriptors were misaligned within
-the internal buffer, causing alignment faults on IA64 platforms.
-
-Code and Data Size: These are the sizes for the acpica.lib produced by the
-Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI
-driver or OSPM code. The debug version of the code includes the debug output
-trace mechanism and has a much larger code and data size. Note that these
-values will vary depending on the efficiency of the compiler and the
-compiler options used during generation.

-
-2) iASL Compiler/Disassembler:
-
-Implemented support for new reserved names: _WDG and _WED are Microsoft
-extensions for Windows Instrumentation Management, _TDL is a new ACPI-
-defined method (Throttling Depth Limit.)
-
-Fixed a problem where a zero-length VendorShort or VendorLong resource
-descriptor was incorrectly emitted as a descriptor of length one.
-
-----------------------------------------
-10 February 2006. Summary of changes for version 20060210:
-
-1) ACPI CA Core Subsystem:
-
-Removed a couple of extraneous ACPI_ERROR messages that appeared during
-normal execution. These became apparent after the conversion from
-ACPI_DEBUG_PRINT.
-
-Fixed a problem where the CreateField operator could hang if the BitIndex or
-NumBits parameter referred to a named object. (Valery Podrezov, BZ 5359)
-
-Fixed a problem where a DeRefOf operation on a buffer object incorrectly
-failed with an exception. This also fixes a couple of related RefOf and
-DeRefOf issues. (Valery Podrezov, BZ 5360/5392/5387)
-
-Fixed a problem where the AE_BUFFER_LIMIT exception was returned instead of
-AE_STRING_LIMIT on an out-of-bounds Index() operation. (Valery Podrezov, BZ
-5480)
-
-Implemented a memory cleanup at the end of the execution of each iteration
-of an AML While() loop, preventing the accumulation of outstanding objects.
-(Valery Podrezov, BZ 5427)
-
-Eliminated a chunk of duplicate code in the object resolution code. (Valery
-Podrezov, BZ 5336)
-
-Fixed several warnings during the 64-bit code generation.
-
-The AcpiSrc source code conversion tool now inserts one line of whitespace
-after an if() statement that is followed immediately by a comment, improving
-readability of the Linux code.
-
-Code and Data Size: The current and previous library sizes for the core
-subsystem are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
-values do not include any ACPI driver or OSPM code. The debug version of the
-code includes the debug output trace mechanism and has a much larger code
-and data size. Note that these values will vary depending on the efficiency
-of the compiler and the compiler options used during generation.

-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a problem with the disassembly of a BankField operator with a complex
-expression for the BankValue parameter.
-
-----------------------------------------
-27 January 2006. Summary of changes for version 20060127:
-
-1) ACPI CA Core Subsystem:
-
-Implemented support in the Resource Manager to allow unresolved namestring
-references within resource package objects for the _PRT method. This support
-is in addition to the previously implemented unresolved reference support
-within the AML parser. If the interpreter slack mode is enabled, these
-unresolved references will be passed through to the caller as a NULL package
-entry.
-
-Implemented and deployed new macros and functions for error and warning
-messages across the subsystem. These macros are simpler and generate less
-code than their predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION,
-ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_* macros. The older
-macros remain defined to allow ACPI drivers time to migrate to the new
-macros.
-
-Implemented the ACPI_CPU_FLAGS type to simplify host OS integration of the
-Acquire/Release Lock OSL interfaces.
-
-Fixed a problem where Alias ASL operators are sometimes not correctly
-resolved, in both the interpreter and the iASL compiler.
-
-Fixed several problems with the implementation of the ConcatenateResTemplate
-ASL operator. As per the ACPI specification, zero length buffers are now
-treated as a single EndTag. One-length buffers always cause a fatal
-exception. Non-zero length buffers that do not end with a full 2-byte EndTag
-cause a fatal exception.
-
-Fixed a possible structure overwrite in the AcpiGetObjectInfo external
-interface. (With assistance from Thomas Renninger)
-
-Code and Data Size: The current and previous library sizes for the core
-subsystem are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
-values do not include any ACPI driver or OSPM code. The debug version of the
-code includes the debug output trace mechanism and has a much larger code
-and data size. Note that these values will vary depending on the efficiency
-of the compiler and the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 83.1K Code, 18.4K Data, 101.5K Total
- Debug Version: 163.2K Code, 66.2K Data, 229.4K Total
- Current Release:
- Non-Debug Version: 81.0K Code, 17.9K Data, 98.9K Total
- Debug Version: 161.3K Code, 65.7K Data, 227.0K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed an internal error that was generated for any forward references to ASL
-Alias objects.
-
-----------------------------------------
-13 January 2006. Summary of changes for version 20060113:
-
-1) ACPI CA Core Subsystem:
-
-Added 2006 copyright to all module headers and signons. This affects
-virtually every file in the ACPICA core subsystem, iASL compiler, and the
-utilities.
-
-Enhanced the ACPICA error reporting in order to simplify user migration to
-the non-debug version of ACPICA. Replaced all instances of the
-ACPI_DEBUG_PRINT macro invoked at the ACPI_DB_ERROR and ACPI_DB_WARN debug
-levels with the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros,
-respectively. This preserves all error and warning messages in the non-debug
-version of the ACPICA code (this has been referred to as the "debug lite"
-option.) Over 200 cases were converted to create a total of over 380
-error/warning messages across the ACPICA code. This increases the code and
-data size of the default non-debug version of the code somewhat (about 13K),
-but all error/warning reporting may be disabled if desired (and code
-eliminated) by specifying the ACPI_NO_ERROR_MESSAGES compile-time
-configuration option. The size of the debug version of ACPICA remains about
-the same.
-
-Fixed a memory leak within the AML Debugger "Set" command. One object was
-not properly deleted for every successful invocation of the command.
-
-Code and Data Size: The current and previous library sizes for the core
-subsystem are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
-values do not include any ACPI driver or OSPM code. The debug version of the
-code includes the debug output trace mechanism and has a much larger code
-and data size. Note that these values will vary depending on the efficiency
-of the compiler and the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 76.6K Code, 12.3K Data, 88.9K Total
- Debug Version: 163.7K Code, 67.5K Data, 231.2K Total
- Current Release:
- Non-Debug Version: 83.1K Code, 18.4K Data, 101.5K Total
- Debug Version: 163.2K Code, 66.2K Data, 229.4K Total
-
-
-2) iASL Compiler/Disassembler:
-
-The compiler now officially supports the ACPI 3.0a specification that was
-released on December 30, 2005. (Specification is available at www.acpi.info)
-
-----------------------------------------
-16 December 2005. Summary of changes for version 20051216:
-
-1) ACPI CA Core Subsystem:
-
-Implemented optional support to allow unresolved names within ASL Package
-objects. A null object is inserted in the package when a named reference
-cannot be located in the current namespace. Enabled via the interpreter
-slack flag, this should eliminate AE_NOT_FOUND exceptions seen on machines
-that contain such code.
-
-Implemented an optimization to the initialization sequence that can improve
-boot time. During ACPI device initialization, the _STA method is now run if
-and only if the _INI method exists. The _STA method is used to determine if
-the device is present; An _INI can only be run if _STA returns present, but
-it is a waste of time to run the _STA method if the _INI does not exist.
-(Prototype and assistance from Dong Wei)
-
-Implemented use of the C99 uintptr_t for the pointer casting macros if it is
-available in the current compiler. Otherwise, the default (void *) cast is
-used as before.
-
-Fixed some possible memory leaks found within the execution path of the
-Break, Continue, If, and CreateField operators. (Valery Podrezov)
-
-Fixed a problem introduced in the 20051202 release where an exception is
-generated during method execution if a control method attempts to declare
-another method.
-
-Moved resource descriptor string constants that are used by both the AML
-disassembler and AML debugger to the common utilities directory so that
-these components are independent.
-
-Implemented support in the AcpiExec utility (-e switch) to globally ignore
-exceptions during control method execution (method is not aborted.)
-
-Added the rsinfo.c source file to the AcpiExec makefile for Linux/Unix
-generation.
-
-Code and Data Size: The current and previous library sizes for the core
-subsystem are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
-values do not include any ACPI driver or OSPM code. The debug version of the
-code includes the debug output trace mechanism and has a much larger code
-and data size. Note that these values will vary depending on the efficiency
-of the compiler and the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total
- Debug Version: 163.2K Code, 67.4K Data, 230.6K Total
- Current Release:
- Non-Debug Version: 76.6K Code, 12.3K Data, 88.9K Total
- Debug Version: 163.7K Code, 67.5K Data, 231.2K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a problem where a CPU stack overflow fault could occur if a recursive
-method call was made from within a Return statement.
-
-----------------------------------------
-02 December 2005. Summary of changes for version 20051202:
-
-1) ACPI CA Core Subsystem:
-
-Modified the parsing of control methods to no longer create namespace
-objects during the first pass of the parse. Objects are now created only
-during the execute phase, at the moment the namespace creation operator is
-encountered in the AML (Name, OperationRegion, CreateByteField, etc.) This
-should eliminate ALREADY_EXISTS exceptions seen on some machines where
-reentrant control methods are protected by an AML mutex. The mutex will now
-correctly block multiple threads from attempting to create the same object
-more than once.
-
-Increased the number of available Owner Ids for namespace object tracking
-from 32 to 255. This should eliminate the OWNER_ID_LIMIT exceptions seen on
-some machines with a large number of ACPI tables (either static or dynamic).
-
-Fixed a problem with the AcpiExec utility where a fault could occur when the
--b switch (batch mode) is used.
-
-Enhanced the namespace dump routine to output the owner ID for each
-namespace object.
-
-Code and Data Size: The current and previous library sizes for the core
-subsystem are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
-values do not include any ACPI driver or OSPM code. The debug version of the
-code includes the debug output trace mechanism and has a much larger code
-and data size. Note that these values will vary depending on the efficiency
-of the compiler and the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total
- Debug Version: 163.0K Code, 67.4K Data, 230.4K Total
- Current Release:
- Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total
- Debug Version: 163.2K Code, 67.4K Data, 230.6K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a parse error during compilation of certain Switch/Case constructs. To
-simplify the parse, the grammar now allows for multiple Default statements
-and this error is now detected and flagged during the analysis phase.
-
-Disassembler: The disassembly now includes the contents of the original
-table header within a comment at the start of the file. This includes the
-name and version of the original ASL compiler.
-
-----------------------------------------
-17 November 2005. Summary of changes for version 20051117:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem in the AML parser where the method thread count could be
-decremented below zero if any errors occurred during the method parse phase.
-This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines.
-This also fixed a related regression with the mechanism that detects and
-corrects methods that cannot properly handle reentrancy (related to the
-deployment of the new OwnerId mechanism.)
-
-Eliminated the pre-parsing of control methods (to detect errors) during
-table load. Related to the problem above, this was causing unwind issues if
-any errors occurred during the parse, and it seemed to be overkill. A table
-load should not be aborted if there are problems with any single control
-method, thus rendering this feature rather pointless.
-
-Fixed a problem with the new table-driven resource manager where an internal
-buffer overflow could occur for small resource templates.
-
-Implemented a new external interface, AcpiGetVendorResource. This interface
-will find and return a vendor-defined resource descriptor within a _CRS or
-_PRS method via an ACPI 3.0 UUID match. With assistance from Bjorn Helgaas.
-
-Removed the length limit (200) on string objects as per the upcoming ACPI
-3.0A specification. This affects the following areas of the interpreter: 1)
-any implicit conversion of a Buffer to a String, 2) a String object result
-of the ASL Concatentate operator, 3) the String object result of the ASL
-ToString operator.
-
-Fixed a problem in the Windows OS interface layer (OSL) where a WAIT_FOREVER
-on a semaphore object would incorrectly timeout. This allows the
-multithreading features of the AcpiExec utility to work properly under
-Windows.
-
-Updated the Linux makefiles for the iASL compiler and AcpiExec to include
-the recently added file named "utresrc.c".
-
-Code and Data Size: The current and previous library sizes for the core
-subsystem are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
-values do not include any ACPI driver or OSPM code. The debug version of the
-code includes the debug output trace mechanism and has a much larger code
-and data size. Note that these values will vary depending on the efficiency
-of the compiler and the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 76.2K Code, 12.3K Data, 88.5K Total
- Debug Version: 163.0K Code, 67.4K Data, 230.4K Total
- Current Release:
- Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total
- Debug Version: 163.0K Code, 67.4K Data, 230.4K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Removed the limit (200) on string objects as per the upcoming ACPI 3.0A
-specification. For the iASL compiler, this means that string literals within
-the source ASL can be of any length.
-
-Enhanced the listing output to dump the AML code for resource descriptors
-immediately after the ASL code for each descriptor, instead of in a block at
-the end of the entire resource template.
-
-Enhanced the compiler debug output to dump the entire original parse tree
-constructed during the parse phase, before any transforms are applied to the
-tree. The transformed tree is dumped also.
-
-----------------------------------------
-02 November 2005. Summary of changes for version 20051102:
-
-1) ACPI CA Core Subsystem:
-
-Modified the subsystem initialization sequence to improve GPE support. The
-GPE initialization has been split into two parts in order to defer execution
-of the _PRW methods (Power Resources for Wake) until after the hardware is
-fully initialized and the SCI handler is installed. This allows the _PRW
-methods to access fields protected by the Global Lock. This will fix systems
-where a NO_GLOBAL_LOCK exception has been seen during initialization.
-
-Converted the ACPI internal object disassemble and display code within the
-AML debugger to fully table-driven operation, reducing code size and
-increasing maintainability.
-
-Fixed a regression with the ConcatenateResTemplate() ASL operator introduced
-in the 20051021 release.
-
-Implemented support for "local" internal ACPI object types within the
-debugger "Object" command and the AcpiWalkNamespace external interfaces.
-These local types include RegionFields, BankFields, IndexFields, Alias, and
-reference objects.
-
-Moved common AML resource handling code into a new file, "utresrc.c". This
-code is shared by both the Resource Manager and the AML Debugger.
-
-Code and Data Size: The current and previous library sizes for the core
-subsystem are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
-values do not include any ACPI driver or OSPM code. The debug version of the
-code includes the debug output trace mechanism and has a much larger code
-and data size. Note that these values will vary depending on the efficiency
-of the compiler and the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 76.1K Code, 12.2K Data, 88.3K Total
- Debug Version: 163.5K Code, 67.0K Data, 230.5K Total
- Current Release:
- Non-Debug Version: 76.2K Code, 12.3K Data, 88.5K Total
- Debug Version: 163.0K Code, 67.4K Data, 230.4K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a problem with very large initializer lists (more than 4000 elements)
-for both Buffer and Package objects where the parse stack could overflow.
-
-Enhanced the pre-compile source code scan for non-ASCII characters to ignore
-characters within comment fields. The scan is now always performed and is no
-longer optional, detecting invalid characters within a source file
-immediately rather than during the parse phase or later.
-
-Enhanced the ASL grammar definition to force early reductions on all list-
-style grammar elements so that the overall parse stack usage is greatly
-reduced. This should improve performance and reduce the possibility of parse
-stack overflow.
-
-Eliminated all reduce/reduce conflicts in the iASL parser generation. Also,
-with the addition of a %expected statement, the compiler generates from
-source with no warnings.
-
-Fixed a possible segment fault in the disassembler if the input filename
-does not contain a "dot" extension (Thomas Renninger).
-
-----------------------------------------
-21 October 2005. Summary of changes for version 20051021:
-
-1) ACPI CA Core Subsystem:
-
-Implemented support for the EM64T and other x86-64 processors. This
-essentially entails recognizing that these processors support non-aligned
-memory transfers. Previously, all 64-bit processors were assumed to lack
-hardware support for non-aligned transfers.
-
-Completed conversion of the Resource Manager to nearly full table-driven
-operation. Specifically, the resource conversion code (convert AML to
-internal format and the reverse) and the debug code to dump internal
-resource descriptors are fully table-driven, reducing code and data size and
-improving maintainability.
-
-The OSL interfaces for Acquire and Release Lock now use a 64-bit flag word
-on 64-bit processors instead of a fixed 32-bit word. (With assistance from
-Alexey Starikovskiy)
-
-Implemented support within the resource conversion code for the Type-
-Specific byte within the various ACPI 3.0 *WordSpace macros.
-
-Fixed some issues within the resource conversion code for the type-specific
-flags for both Memory and I/O address resource descriptors. For Memory,
-implemented support for the MTP and TTP flags. For I/O, split the TRS and
-TTP flags into two separate fields.
-
-Code and Data Size: The current and previous library sizes for the core
-subsystem are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
-values do not include any ACPI driver or OSPM code. The debug version of the
-code includes the debug output trace mechanism and has a much larger code
-and data size. Note that these values will vary depending on the efficiency
-of the compiler and the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 77.1K Code, 12.1K Data, 89.2K Total
- Debug Version: 168.0K Code, 68.3K Data, 236.3K Total
- Current Release:
- Non-Debug Version: 76.1K Code, 12.2K Data, 88.3K Total
- Debug Version: 163.5K Code, 67.0K Data, 230.5K Total
-
-
-
-2) iASL Compiler/Disassembler:
-
-Relaxed a compiler restriction that disallowed a ResourceIndex byte if the
-corresponding ResourceSource string was not also present in a resource
-descriptor declaration. This restriction caused problems with existing
-AML/ASL code that includes the Index byte without the string. When such AML
-was disassembled, it could not be compiled without modification. Further,
-the modified code created a resource template with a different size than the
-original, breaking code that used fixed offsets into the resource template
-buffer.
-
-Removed a recent feature of the disassembler to ignore a lone ResourceIndex
-byte. This byte is now emitted if present so that the exact AML can be
-reproduced when the disassembled code is recompiled.
-
-Improved comments and text alignment for the resource descriptor code
-emitted by the disassembler.
-
-Implemented disassembler support for the ACPI 3.0 AccessSize field within a
-Register() resource descriptor.
-
-----------------------------------------
-30 September 2005. Summary of changes for version 20050930:
-
-1) ACPI CA Core Subsystem:
-
-Completed a major overhaul of the Resource Manager code - specifically,
-optimizations in the area of the AML/internal resource conversion code. The
-code has been optimized to simplify and eliminate duplicated code, CPU stack
-use has been decreased by optimizing function parameters and local
-variables, and naming conventions across the manager have been standardized
-for clarity and ease of maintenance (this includes function, parameter,
-variable, and struct/typedef names.) The update may force changes in some
-driver code, depending on how resources are handled by the host OS.
-
-All Resource Manager dispatch and information tables have been moved to a
-single location for clarity and ease of maintenance. One new file was
-created, named "rsinfo.c".
-
-The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to
-guarantee that the argument is not evaluated twice, making them less prone
-to macro side-effects. However, since there exists the possibility of
-additional stack use if a particular compiler cannot optimize them (such as
-in the debug generation case), the original macros are optionally available.
-Note that some invocations of the return_VALUE macro may now cause size
-mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to
-eliminate these. (From Randy Dunlap)
-
-Implemented a new mechanism to enable debug tracing for individual control
-methods. A new external interface, AcpiDebugTrace, is provided to enable
-this mechanism. The intent is to allow the host OS to easily enable and
-disable tracing for problematic control methods. This interface can be
-easily exposed to a user or debugger interface if desired. See the file
-psxface.c for details.
-
-AcpiUtCallocate will now return a valid pointer if a length of zero is
-specified - a length of one is used and a warning is issued. This matches
-the behavior of AcpiUtAllocate.
-
-Code and Data Size: The current and previous library sizes for the core
-subsystem are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
-values do not include any ACPI driver or OSPM code. The debug version of the
-code includes the debug output trace mechanism and has a much larger code
-and data size. Note that these values will vary depending on the efficiency
-of the compiler and the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 77.5K Code, 12.0K Data, 89.5K Total
- Debug Version: 168.1K Code, 68.4K Data, 236.5K Total
- Current Release:
- Non-Debug Version: 77.1K Code, 12.1K Data, 89.2K Total
- Debug Version: 168.0K Code, 68.3K Data, 236.3K Total
-
-
-2) iASL Compiler/Disassembler:
-
-A remark is issued if the effective compile-time length of a package or
-buffer is zero. Previously, this was a warning.
-
-----------------------------------------
-16 September 2005. Summary of changes for version 20050916:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem within the Resource Manager where support for the Generic
-Register descriptor was not fully implemented. This descriptor is now fully
-recognized, parsed, disassembled, and displayed.
-
-Completely restructured the Resource Manager code to utilize table-driven
-dispatch and lookup, eliminating many of the large switch() statements. This
-reduces overall subsystem code size and code complexity. Affects the
-resource parsing and construction, disassembly, and debug dump output.
-
-Cleaned up and restructured the debug dump output for all resource
-descriptors. Improved readability of the output and reduced code size.
-
-Fixed a problem where changes to internal data structures caused the
-optional ACPI_MUTEX_DEBUG code to fail compilation if specified.
-
-Code and Data Size: The current and previous library sizes for the core
-subsystem are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These
-values do not include any ACPI driver or OSPM code. The debug version of the
-code includes the debug output trace mechanism and has a much larger code
-and data size. Note that these values will vary depending on the efficiency
-of the compiler and the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 78.4K Code, 11.8K Data, 90.2K Total
- Debug Version: 169.6K Code, 69.9K Data, 239.5K Total
- Current Release:
- Non-Debug Version: 77.5K Code, 12.0K Data, 89.5K Total
- Debug Version: 168.1K Code, 68.4K Data, 236.5K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Updated the disassembler to automatically insert an EndDependentFn() macro
-into the ASL stream if this macro is missing in the original AML code,
-simplifying compilation of the resulting ASL module.
-
-Fixed a problem in the disassembler where a disassembled ResourceSource
-string (within a large resource descriptor) was not surrounded by quotes and
-not followed by a comma, causing errors when the resulting ASL module was
-compiled. Also, escape sequences within a ResourceSource string are now
-handled correctly (especially "\\")
-
-----------------------------------------
-02 September 2005. Summary of changes for version 20050902:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem with the internal Owner ID allocation and deallocation
-mechanisms for control method execution and recursive method invocation.
-This should eliminate the OWNER_ID_LIMIT exceptions and "Invalid OwnerId"
-messages seen on some systems. Recursive method invocation depth is
-currently limited to 255. (Alexey Starikovskiy)
-
-Completely eliminated all vestiges of support for the "module-level
-executable code" until this support is fully implemented and debugged. This
-should eliminate the NO_RETURN_VALUE exceptions seen during table load on
-some systems that invoke this support.
-
-Fixed a problem within the resource manager code where the transaction flags
-for a 64-bit address descriptor were handled incorrectly in the type-
-specific flag byte.
-
-Consolidated duplicate code within the address descriptor resource manager
-code, reducing overall subsystem code size.
-
-Fixed a fault when using the AML debugger "disassemble" command to
-disassemble individual control methods.
-
-Removed references to the "release_current" directory within the Unix
-release package.
-
-Code and Data Size: The current and previous core subsystem library sizes
-are shown below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler. These values do not
-include any ACPI driver or OSPM code. The debug version of the code includes
-the debug output trace mechanism and has a much larger code and data size.
-Note that these values will vary depending on the efficiency of the compiler
-and the compiler options used during generation.

-
-----------------------------------------
-15 August 2005. Summary of changes for version 20050815:
-
-1) ACPI CA Core Subsystem:
-
-Implemented a full bytewise compare to determine if a table load request is
-attempting to load a duplicate table. The compare is performed if the table
-signatures and table lengths match. This will allow different tables with
-the same OEM Table ID and revision to be loaded - probably against the ACPI
-specification, but discovered in the field nonetheless.
-
-Added the changes.txt logfile to each of the zipped release packages.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-
-2) iASL Compiler/Disassembler:
-
-Fixed a problem where incorrect AML code could be generated for Package
-objects if optimization is disabled (via the -oa switch).
-

-length packages when the package length is not specified and the number of
-initializer values is greater than 255.
-
-
-----------------------------------------
-29 July 2005. Summary of changes for version 20050729:
-
-1) ACPI CA Core Subsystem:
-
-Implemented support to ignore an attempt to install/load a particular ACPI
-table more than once. Apparently there exists BIOS code that repeatedly
-attempts to load the same SSDT upon certain events. With assistance from
-Venkatesh Pallipadi.
-
-Restructured the main interface to the AML parser in order to correctly
-handle all exceptional conditions. This will prevent leakage of the OwnerId
-resource and should eliminate the AE_OWNER_ID_LIMIT exceptions seen on some
-machines. With assistance from Alexey Starikovskiy.
-
-Support for "module level code" has been disabled in this version due to a
-number of issues that have appeared on various machines. The support can be
-enabled by defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem
-compilation. When the issues are fully resolved, the code will be enabled by
-default again.
-
-Modified the internal functions for debug print support to define the
-FunctionName parameter as a (const char *) for compatibility with compiler
-built-in macros such as __FUNCTION__, etc.
-
-Linted the entire ACPICA source tree for both 32-bit and 64-bit.
-
-Implemented support to display an object count summary for the AML Debugger
-commands Object and Methods.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

- Non-Debug Version: 78.6K Code, 11.7K Data, 90.3K Total
- Debug Version: 167.0K Code, 69.9K Data, 236.9K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a regression that appeared in the 20050708 version of the compiler
-where an error message was inadvertently emitted for invocations of the _OSI
-reserved control method.
-
-----------------------------------------
-08 July 2005. Summary of changes for version 20050708:
-
-1) ACPI CA Core Subsystem:
-
-The use of the CPU stack in the debug version of the subsystem has been
-considerably reduced. Previously, a debug structure was declared in every
-function that used the debug macros. This structure has been removed in
-favor of declaring the individual elements as parameters to the debug
-functions. This reduces the cumulative stack use during nested execution of
-ACPI function calls at the cost of a small increase in the code size of the
-debug version of the subsystem. With assistance from Alexey Starikovskiy and
-Len Brown.
-
-Added the ACPI_GET_FUNCTION_NAME macro to enable the compiler-dependent
-headers to define a macro that will return the current function name at
-runtime (such as __FUNCTION__ or _func_, etc.) The function name is used by
-the debug trace output. If ACPI_GET_FUNCTION_NAME is not defined in the
-compiler-dependent header, the function name is saved on the CPU stack (one
-pointer per function.) This mechanism is used because apparently there
-exists no standard ANSI-C defined macro that that returns the function name.
-
-Redesigned and reimplemented the "Owner ID" mechanism used to track
-namespace objects created/deleted by ACPI tables and control method
-execution. A bitmap is now used to allocate and free the IDs, thus solving
-the wraparound problem present in the previous implementation. The size of
-the namespace node descriptor was reduced by 2 bytes as a result (Alexey
-Starikovskiy).
-
-Removed the UINT32_BIT and UINT16_BIT types that were used for the bitfield
-flag definitions within the headers for the predefined ACPI tables. These
-have been replaced by UINT8_BIT in order to increase the code portability of
-the subsystem. If the use of UINT8 remains a problem, we may be forced to
-eliminate bitfields entirely because of a lack of portability.
-
-Enhanced the performance of the AcpiUtUpdateObjectReference procedure. This
-is a frequently used function and this improvement increases the performance
-of the entire subsystem (Alexey Starikovskiy).
-
-Fixed several possible memory leaks and the inverse - premature object
-deletion (Alexey Starikovskiy).
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-
-----------------------------------------
-24 June 2005. Summary of changes for version 20050624:
-
-1) ACPI CA Core Subsystem:
-
-Modified the new OSL cache interfaces to use ACPI_CACHE_T as the type for
-the host-defined cache object. This allows the OSL implementation to define
-and type this object in any manner desired, simplifying the OSL
-implementation. For example, ACPI_CACHE_T is defined as kmem_cache_t for
-Linux, and should be defined in the OS-specific header file for other
-operating systems as required.
-
-Changed the interface to AcpiOsAcquireObject to directly return the
-requested object as the function return (instead of ACPI_STATUS.) This
-change was made for performance reasons, since this is the purpose of the
-interface in the first place. AcpiOsAcquireObject is now similar to the
-AcpiOsAllocate interface.
-
-Implemented a new AML debugger command named Businfo. This command displays
-information about all devices that have an associate _PRT object. The _ADR,
-_HID, _UID, and _CID are displayed for these devices.
-
-Modified the initialization sequence in AcpiInitializeSubsystem to call the
-OSL interface AcpiOslInitialize first, before any local initialization. This
-change was required because the global initialization now calls OSL
-interfaces.
-
-Enhanced the Dump command to display the entire contents of Package objects
-(including all sub-objects and their values.)
-
-Restructured the code base to split some files because of size and/or
-because the code logically belonged in a separate file. New files are listed
-below. All makefiles and project files included in the ACPI CA release have
-been updated.
- utilities/utcache.c /* Local cache interfaces */
- utilities/utmutex.c /* Local mutex support */
- utilities/utstate.c /* State object support */
- interpreter/parser/psloop.c /* Main AML parse loop */
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 78.3K Code, 11.6K Data, 89.9K Total
- Debug Version: 164.0K Code, 69.1K Data, 233.1K Total

- Non-Debug Version: 78.6K Code, 11.5K Data, 90.1K Total
- Debug Version: 165.2K Code, 69.6K Data, 234.8K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a regression introduced in version 20050513 where the use of a Package
-object within a Case() statement caused a compile time exception. The
-original behavior has been restored (a Match() operator is emitted.)
-
-----------------------------------------
-17 June 2005. Summary of changes for version 20050617:
-
-1) ACPI CA Core Subsystem:
-
-Moved the object cache operations into the OS interface layer (OSL) to allow
-the host OS to handle these operations if desired (for example, the Linux
-OSL will invoke the slab allocator). This support is optional; the compile
-time define ACPI_USE_LOCAL_CACHE may be used to utilize the original cache
-code in the ACPI CA core. The new OSL interfaces are shown below. See
-utalloc.c for an example implementation, and acpiosxf.h for the exact
-interface definitions. With assistance from Alexey Starikovskiy.
- AcpiOsCreateCache
- AcpiOsDeleteCache
- AcpiOsPurgeCache
- AcpiOsAcquireObject
- AcpiOsReleaseObject
-
-Modified the interfaces to AcpiOsAcquireLock and AcpiOsReleaseLock to return
-and restore a flags parameter. This fits better with many OS lock models.
-Note: the current execution state (interrupt handler or not) is no longer
-passed to these interfaces. If necessary, the OSL must determine this state
-by itself, a simple and fast operation. With assistance from Alexey
-Starikovskiy.
-
-Fixed a problem in the ACPI table handling where a valid XSDT was assumed
-present if the revision of the RSDP was 2 or greater. According to the ACPI
-specification, the XSDT is optional in all cases, and the table manager
-therefore now checks for both an RSDP >=2 and a valid XSDT pointer.
-Otherwise, the RSDT pointer is used. Some ACPI 2.0 compliant BIOSs contain
-only the RSDT.
-
-Fixed an interpreter problem with the Mid() operator in the case of an input
-string where the resulting output string is of zero length. It now correctly
-returns a valid, null terminated string object instead of a string object
-with a null pointer.
-
-Fixed a problem with the control method argument handling to allow a store
-to an Arg object that already contains an object of type Device. The Device
-object is now correctly overwritten. Previously, an error was returned.
-
-
-Enhanced the debugger Find command to emit object values in addition to the
-found object pathnames. The output format is the same as the dump namespace
-command.
-
-Enhanced the debugger Set command. It now has the ability to set the value
-of any Named integer object in the namespace (Previously, only method locals
-and args could be set.)
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 78.1K Code, 11.6K Data, 89.7K Total
- Debug Version: 164.0K Code, 69.3K Data, 233.3K Total
- Current Release:
- Non-Debug Version: 78.3K Code, 11.6K Data, 89.9K Total
- Debug Version: 164.0K Code, 69.1K Data, 233.1K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a regression in the disassembler where if/else/while constructs were
-output incorrectly. This problem was introduced in the previous release
-(20050526). This problem also affected the single-step disassembly in the
-debugger.
-
-Fixed a problem where compiling the reserved _OSI method would randomly (but
-rarely) produce compile errors.
-
-Enhanced the disassembler to emit compilable code in the face of incorrect
-AML resource descriptors. If the optional ResourceSourceIndex is present,
-but the ResourceSource is not, do not emit the ResourceSourceIndex in the
-disassembly. Otherwise, the resulting code cannot be compiled without
-errors.
-
-----------------------------------------
-26 May 2005. Summary of changes for version 20050526:
-
-1) ACPI CA Core Subsystem:
-
-Implemented support to execute Type 1 and Type 2 AML opcodes appearing at
-the module level (not within a control method.) These opcodes are executed
-exactly once at the time the table is loaded. This type of code was legal up
-until the release of ACPI 2.0B (2002) and is now supported within ACPI CA in
-order to provide backwards compatibility with earlier BIOS implementations.
-This eliminates the "Encountered executable code at module level" warning
-that was previously generated upon detection of such code.
-
-Fixed a problem in the interpreter where an AE_NOT_FOUND exception could
-inadvertently be generated during the lookup of namespace objects in the
-second pass parse of ACPI tables and control methods. It appears that this
-problem could occur during the resolution of forward references to namespace
-objects.
-
-Added the ACPI_MUTEX_DEBUG #ifdef to the AcpiUtReleaseMutex function,
-corresponding to the same #ifdef in the AcpiUtAcquireMutex function. This
-allows the deadlock detection debug code to be compiled out in the normal
-case, improving mutex performance (and overall subsystem performance)
-considerably.
-
-Implemented a handful of miscellaneous fixes for possible memory leaks on
-error conditions and error handling control paths. These fixes were
-suggested by FreeBSD and the Coverity Prevent source code analysis tool.
-
-Added a check for a null RSDT pointer in AcpiGetFirmwareTable (tbxfroot.c)
-to prevent a fault in this error case.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

- Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total
- Debug Version: 163.7K Code, 69.3K Data, 233.0K Total
- Current Release:
- Non-Debug Version: 78.1K Code, 11.6K Data, 89.7K Total
- Debug Version: 164.0K Code, 69.3K Data, 233.3K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Implemented support to allow Type 1 and Type 2 ASL operators to appear at
-the module level (not within a control method.) These operators will be
-executed once at the time the table is loaded. This type of code was legal
-up until the release of ACPI 2.0B (2002) and is now supported by the iASL
-compiler in order to provide backwards compatibility with earlier BIOS ASL
-code.
-
-The ACPI integer width (specified via the table revision ID or the -r
-override, 32 or 64 bits) is now used internally during compile-time constant
-folding to ensure that constants are truncated to 32 bits if necessary.
-Previously, the revision ID value was only emitted in the AML table header.
-
-An error message is now generated for the Mutex and Method operators if the
-SyncLevel parameter is outside the legal range of 0 through 15.
-
-Fixed a problem with the Method operator ParameterTypes list handling (ACPI
-3.0). Previously, more than 2 types or 2 arguments generated a syntax error.
-The actual underlying implementation of method argument typechecking is
-still under development, however.
-
-----------------------------------------
-13 May 2005. Summary of changes for version 20050513:
-
-1) ACPI CA Core Subsystem:
-
-Implemented support for PCI Express root bridges -- added support for device
-PNP0A08 in the root bridge search within AcpiEvPciConfigRegionSetup.
-
-The interpreter now automatically truncates incoming 64-bit constants to 32
-bits if currently executing out of a 32-bit ACPI table (Revision < 2). This
-also affects the iASL compiler constant folding. (Note: as per below, the
-iASL compiler no longer allows 64-bit constants within 32-bit tables.)
-
-Fixed a problem where string and buffer objects with "static" pointers
-(pointers to initialization data within an ACPI table) were not handled
-consistently. The internal object copy operation now always copies the data
-to a newly allocated buffer, regardless of whether the source object is
-static or not.
-
-Fixed a problem with the FromBCD operator where an implicit result
-conversion was improperly performed while storing the result to the target
-operand. Since this is an "explicit conversion" operator, the implicit
-conversion should never be performed on the output.
-
-Fixed a problem with the CopyObject operator where a copy to an existing
-named object did not always completely overwrite the existing object stored
-at name. Specifically, a buffer-to-buffer copy did not delete the existing
-buffer.
-
-Replaced "InterruptLevel" with "InterruptNumber" in all GPE interfaces and
-structs for consistency.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

- Debug Version: 163.7K Code, 69.3K Data, 233.0K Total
- Current Release: (Same sizes)
- Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total
- Debug Version: 163.7K Code, 69.3K Data, 233.0K Total
-
-
-2) iASL Compiler/Disassembler:
-
-The compiler now emits a warning if an attempt is made to generate a 64-bit
-integer constant from within a 32-bit ACPI table (Revision < 2). The integer
-is truncated to 32 bits.
-
-Fixed a problem with large package objects: if the static length of the
-package is greater than 255, the "variable length package" opcode is
-emitted. Previously, this caused an error. This requires an update to the
-ACPI spec, since it currently (incorrectly) states that packages larger than
-255 elements are not allowed.
-
-The disassembler now correctly handles variable length packages and packages
-larger than 255 elements.
-
-----------------------------------------
-08 April 2005. Summary of changes for version 20050408:
-
-1) ACPI CA Core Subsystem:
-
-Fixed three cases in the interpreter where an "index" argument to an ASL
-function was still (internally) 32 bits instead of the required 64 bits.
-This was the Index argument to the Index, Mid, and Match operators.
-
-The "strupr" function is now permanently local (AcpiUtStrupr), since this is
-not a POSIX-defined function and not present in most kernel-level C
-libraries. All references to the C library strupr function have been removed
-from the headers.
-
-Completed the deployment of static functions/prototypes. All prototypes with
-the static attribute have been moved from the headers to the owning C file.
-
-Implemented an extract option (-e) for the AcpiBin utility (AML binary
-utility). This option allows the utility to extract individual ACPI tables
-from the output of AcpiDmp. It provides the same functionality of the
-acpixtract.pl perl script without the worry of setting the correct perl
-options. AcpiBin runs on Windows and has not yet been generated/validated in
-the Linux/Unix environment (but should be soon).
-
-Updated and fixed the table dump option for AcpiBin (-d). This option
-converts a single ACPI table to a hex/ascii file, similar to the output of
-AcpiDmp.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

- Debug Version: 163.7K Code, 69.3K Data, 233.0K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Disassembler fix: Added a check to ensure that the table length found in the
-ACPI table header within the input file is not longer than the actual input
-file size. This indicates some kind of file or table corruption.
-
-----------------------------------------
-29 March 2005. Summary of changes for version 20050329:
-
-1) ACPI CA Core Subsystem:
-
-An error is now generated if an attempt is made to create a Buffer Field of
-length zero (A CreateField with a length operand of zero.)
-
-The interpreter now issues a warning whenever executable code at the module
-level is detected during ACPI table load. This will give some idea of the
-prevalence of this type of code.
-
-Implemented support for references to named objects (other than control
-methods) within package objects.
-
-Enhanced package object output for the debug object. Package objects are now
-completely dumped, showing all elements.
-
-Enhanced miscellaneous object output for the debug object. Any object can
-now be written to the debug object (for example, a device object can be
-written, and the type of the object will be displayed.)
-
-The "static" qualifier has been added to all local functions across both the
-core subsystem and the iASL compiler.
-
-The number of "long" lines (> 80 chars) within the source has been
-significantly reduced, by about 1/3.
-
-Cleaned up all header files to ensure that all CA/iASL functions are
-prototyped (even static functions) and the formatting is consistent.
-
-Two new header files have been added, acopcode.h and acnames.h.
-
-Removed several obsolete functions that were no longer used.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

- Debug Version: 163.5K Code, 69.3K Data, 232.8K Total
-
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a problem with the resource descriptor generation/support. For the
-ResourceSourceIndex and the ResourceSource fields, both must be present, or
-both must be not present - can't have one without the other.
-
-The compiler now returns non-zero from the main procedure if any errors have
-occurred during the compilation.
-
-
-----------------------------------------
-09 March 2005. Summary of changes for version 20050309:
-
-1) ACPI CA Core Subsystem:
-
-The string-to-buffer implicit conversion code has been modified again after
-a change to the ACPI specification. In order to match the behavior of the
-other major ACPI implementation, the target buffer is no longer truncated if
-the source string is smaller than an existing target buffer. This change
-requires an update to the ACPI spec, and should eliminate the recent
-AE_AML_BUFFER_LIMIT issues.
-
-The "implicit return" support was rewritten to a new algorithm that solves
-the general case. Rather than attempt to determine when a method is about to
-exit, the result of every ASL operator is saved momentarily until the very
-next ASL operator is executed. Therefore, no matter how the method exits,
-there will always be a saved implicit return value. This feature is only
-enabled with the AcpiGbl_EnableInterpreterSlack flag, and should eliminate
-AE_AML_NO_RETURN_VALUE errors when enabled.
-
-Implemented implicit conversion support for the predicate (operand) of the
-If, Else, and While operators. String and Buffer arguments are automatically
-converted to Integers.
-
-Changed the string-to-integer conversion behavior to match the new ACPI
-errata: "If no integer object exists, a new integer is created. The ASCII
-string is interpreted as a hexadecimal constant. Each string character is
-interpreted as a hexadecimal value ('0'-'9', 'A'-'F', 'a', 'f'), starting
-with the first character as the most significant digit, and ending with the
-first non-hexadecimal character or end-of-string." This means that the first
-non-hex character terminates the conversion and this is the code that was
-changed.
-
-Fixed a problem where the ObjectType operator would fail (fault) when used
-on an Index of a Package which pointed to a null package element. The
-operator now properly returns zero (Uninitialized) in this case.
-
-Fixed a problem where the While operator used excessive memory by not
-properly popping the result stack during execution. There was no memory leak
-after execution, however. (Code provided by Valery Podrezov.)
-
-Fixed a problem where references to control methods within Package objects
-caused the method to be invoked, instead of producing a reference object
-pointing to the method.
-
-Restructured and simplified the pswalk.c module (AcpiPsDeleteParseTree) to
-improve performance and reduce code size. (Code provided by Alexey
-Starikovskiy.)
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

- Previous Release:
- Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total
- Debug Version: 165.4K Code, 69.6K Data, 236.0K Total
- Current Release:

- Debug Version: 165.4K Code, 69.7K Data, 236.1K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a problem with the Return operator with no arguments. Since the AML
-grammar for the byte encoding requires an operand for the Return opcode, the
-compiler now emits a Return(Zero) for this case. An ACPI specification
-update has been written for this case.
-
-For tables other than the DSDT, namepath optimization is automatically
-disabled. This is because SSDTs can be loaded anywhere in the namespace, the
-compiler has no knowledge of where, and thus cannot optimize namepaths.
-
-Added "ProcessorObj" to the ObjectTypeKeyword list. This object type was
-inadvertently omitted from the ACPI specification, and will require an
-update to the spec.
-
-The source file scan for ASCII characters is now optional (-a). This change
-was made because some vendors place non-ascii characters within comments.
-However, the scan is simply a brute-force byte compare to ensure all
-characters in the file are in the range 0x00 to 0x7F.
-
-Fixed a problem with the CondRefOf operator where the compiler was
-inappropriately checking for the existence of the target. Since the point of
-the operator is to check for the existence of the target at run-time, the
-compiler no longer checks for the target existence.
-
-Fixed a problem where errors generated from the internal AML interpreter
-during constant folding were not handled properly, causing a fault.
-
-Fixed a problem with overly aggressive range checking for the Stall
-operator. The valid range (max 255) is now only checked if the operand is of
-type Integer. All other operand types cannot be statically checked.
-
-Fixed a problem where control method references within the RefOf, DeRefOf,
-and ObjectType operators were not treated properly. They are now treated as
-actual references, not method invocations.
-
-Fixed and enhanced the "list namespace" option (-ln). This option was broken
-a number of releases ago.
-
-Improved error handling for the Field, IndexField, and BankField operators.
-The compiler now cleanly reports and recovers from errors in the field
-component (FieldUnit) list.
-
-Fixed a disassembler problem where the optional ResourceDescriptor fields
-TRS and TTP were not always handled correctly.
-
-Disassembler - Comments in output now use "//" instead of "/*"
-
-----------------------------------------
-28 February 2005. Summary of changes for version 20050228:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem where the result of an Index() operator (an object
-reference) must increment the reference count on the target object for the
-life of the object reference.
-
-Implemented AML Interpreter and Debugger support for the new ACPI 3.0
-Extended Address (IO, Memory, Space), QwordSpace, DwordSpace, and WordSpace
-resource descriptors.
-
-Implemented support in the _OSI method for the ACPI 3.0 "Extended Address
-Space Descriptor" string, indicating interpreter support for the descriptors
-above.
-
-Implemented header support for the new ACPI 3.0 FADT flag bits.
-
-Implemented header support for the new ACPI 3.0 PCI Express bits for the PM1
-status/enable registers.
-
-Updated header support for the MADT processor local Apic struct and MADT
-platform interrupt source struct for new ACPI 3.0 fields.
-
-Implemented header support for the SRAT and SLIT ACPI tables.
-
-Implemented the -s switch in AcpiExec to enable the "InterpreterSlack" flag
-at runtime.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

- Previous Release:
- Non-Debug Version: 78.2K Code, 11.5K Data, 89.7K Total
- Debug Version: 164.9K Code, 69.2K Data, 234.1K Total
- Current Release:
- Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total
- Debug Version: 165.4K Code, 69.6K Data, 236.0K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a problem with the internal 64-bit String-to-integer conversion with
-strings less than two characters long.
-
-Fixed a problem with constant folding where the result of the Index()
-operator can not be considered a constant. This means that Index() cannot be
-a type3 opcode and this will require an update to the ACPI specification.
-
-Disassembler: Implemented support for the TTP, MTP, and TRS resource
-descriptor fields. These fields were inadvertently ignored and not output in
-the disassembly of the resource descriptor.
-
-
- ----------------------------------------
-11 February 2005. Summary of changes for version 20050211:
-
-1) ACPI CA Core Subsystem:
-
-Implemented ACPI 3.0 support for implicit conversion within the Match()
-operator. MatchObjects can now be of type integer, buffer, or string instead
-of just type integer. Package elements are implicitly converted to the type
-of the MatchObject. This change aligns the behavior of Match() with the
-behavior of the other logical operators (LLess(), etc.) It also requires an
-errata change to the ACPI specification as this support was intended for
-ACPI 3.0, but was inadvertently omitted.
-
-Fixed a problem with the internal implicit "to buffer" conversion. Strings
-that are converted to buffers will cause buffer truncation if the string is
-smaller than the target buffer. Integers that are converted to buffers will
-not cause buffer truncation, only zero extension (both as per the ACPI
-spec.) The problem was introduced when code was added to truncate the
-buffer, but this should not be performed in all cases, only the string case.
-
-Fixed a problem with the Buffer and Package operators where the interpreter
-would get confused if two such operators were used as operands to an ASL
-operator (such as LLess(Buffer(1){0},Buffer(1){1}). The internal result
-stack was not being popped after the execution of these operators, resulting
-in an AE_NO_RETURN_VALUE exception.
-
-Fixed a problem with constructs of the form Store(Index(...),...). The
-reference object returned from Index was inadvertently resolved to an actual
-value. This problem was introduced in version 20050114 when the behavior of
-Store() was modified to restrict the object types that can be used as the
-source operand (to match the ACPI specification.)
-
-Reduced excessive stack use within the AcpiGetObjectInfo procedure.
-
-Added a fix to aclinux.h to allow generation of AcpiExec on Linux.
-
-Updated the AcpiSrc utility to add the FADT_DESCRIPTOR_REV2_MINUS struct.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

- Previous Release:
- Non-Debug Version: 78.1K Code, 11.5K Data, 89.6K Total
- Debug Version: 164.8K Code, 69.2K Data, 234.0K Total
- Current Release:
- Non-Debug Version: 78.2K Code, 11.5K Data, 89.7K Total
- Debug Version: 164.9K Code, 69.2K Data, 234.1K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a code generation problem in the constant folding optimization code
-where incorrect code was generated if a constant was reduced to a buffer
-object (i.e., a reduced type 5 opcode.)
-
-Fixed a typechecking problem for the ToBuffer operator. Caused by an
-incorrect return type in the internal opcode information table.
-
-----------------------------------------
-25 January 2005. Summary of changes for version 20050125:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a recently introduced problem with the Global Lock where the
-underlying semaphore was not created. This problem was introduced in
-version 20050114, and caused an AE_AML_NO_OPERAND exception during an
-Acquire() operation on _GL.
-
-The local object cache is now optional, and is disabled by default. Both
-AcpiExec and the iASL compiler enable the cache because they run in user
-mode and this enhances their performance. #define ACPI_ENABLE_OBJECT_CACHE
-to enable the local cache.
-
-Fixed an issue in the internal function AcpiUtEvaluateObject concerning the
-optional "implicit return" support where an error was returned if no return
-object was expected, but one was implicitly returned. AE_OK is now returned
-in this case and the implicitly returned object is deleted.
-AcpiUtEvaluateObject is only occasionally used, and only to execute reserved
-methods such as _STA and _INI where the return type is known up front.
-
-Fixed a few issues with the internal convert-to-integer code. It now returns
-an error if an attempt is made to convert a null string, a string of only
-blanks/tabs, or a zero-length buffer. This affects both implicit conversion
-and explicit conversion via the ToInteger() operator.
-
-The internal debug code in AcpiUtAcquireMutex has been commented out. It is
-not needed for normal operation and should increase the performance of the
-entire subsystem. The code remains in case it is needed for debug purposes
-again.
-
-The AcpiExec source and makefile are included in the Unix/Linux package for
-the first time.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.
-
- Previous Release:
- Non-Debug Version: 78.4K Code, 11.5K Data, 89.9K Total
- Debug Version: 165.4K Code, 69.4K Data, 234.8K Total
- Current Release:
- Non-Debug Version: 78.1K Code, 11.5K Data, 89.6K Total
- Debug Version: 164.8K Code, 69.2K Data, 234.0K Total
-
-2) iASL Compiler/Disassembler:
-
-Switch/Case support: A warning is now issued if the type of the Switch value
-cannot be determined at compile time. For example, Switch(Arg0) will
-generate the warning, and the type is assumed to be an integer. As per the
-ACPI spec, use a construct such as Switch(ToInteger(Arg0)) to eliminate the
-warning.
-
-Switch/Case support: Implemented support for buffer and string objects as
-the switch value. This is an ACPI 3.0 feature, now that LEqual supports
-buffers and strings.
-
-Switch/Case support: The emitted code for the LEqual() comparisons now uses
-the switch value as the first operand, not the second. The case value is now
-the second operand, and this allows the case value to be implicitly
-converted to the type of the switch value, not the other way around.
-
-Switch/Case support: Temporary variables are now emitted immediately within
-the control method, not at the global level. This means that there are now
-36 temps available per-method, not 36 temps per-module as was the case with
-the earlier implementation (_T_0 through _T_9 and _T_A through _T_Z.)
-
-----------------------------------------
-14 January 2005. Summary of changes for version 20050114:
-
-Added 2005 copyright to all module headers. This affects every module in
-the core subsystem, iASL compiler, and the utilities.
-
-1) ACPI CA Core Subsystem:
-
-Fixed an issue with the String-to-Buffer conversion code where the string
-null terminator was not included in the buffer after conversion, but there
-is existing ASL that assumes the string null terminator is included. This is
-the root of the ACPI_AML_BUFFER_LIMIT regression. This problem was
-introduced in the previous version when the code was updated to correctly
-set the converted buffer size as per the ACPI specification. The ACPI spec
-is ambiguous and will be updated to specify that the null terminator must be
-included in the converted buffer. This also affects the ToBuffer() ASL
-operator.
-
-Fixed a problem with the Mid() ASL/AML operator where it did not work
-correctly on Buffer objects. Newly created sub-buffers were not being marked
-as initialized.
-
-
-Fixed a problem in AcpiTbFindTable where incorrect string compares were
-performed on the OemId and OemTableId table header fields. These fields are
-not null terminated, so strncmp is now used instead of strcmp.
-
-Implemented a restriction on the Store() ASL/AML operator to align the
-behavior with the ACPI specification. Previously, any object could be used
-as the source operand. Now, the only objects that may be used are Integers,
-Buffers, Strings, Packages, Object References, and DDB Handles. If
-necessary, the original behavior can be restored by enabling the
-EnableInterpreterSlack flag.
-
-Enhanced the optional "implicit return" support to allow an implicit return
-value from methods that are invoked externally via the AcpiEvaluateObject
-interface. This enables implicit returns from the _STA and _INI methods,
-for example.
-
-Changed the Revision() ASL/AML operator to return the current version of the
-AML interpreter, in the YYYYMMDD format. Previously, it incorrectly returned
-the supported ACPI version (This is the function of the _REV method).
-
-Updated the _REV predefined method to return the currently supported version
-of ACPI, now 3.
-
-Implemented batch mode option for the AcpiExec utility (-b).
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-----------------------------------------
-10 December 2004. Summary of changes for version 20041210:
-
-ACPI 3.0 support is nearing completion in both the iASL compiler and the
-ACPI CA core subsystem.
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem in the ToDecimalString operator where the resulting string
-length was incorrectly calculated. The length is now calculated exactly,
-eliminating incorrect AE_STRING_LIMIT exceptions.
-
-Fixed a problem in the ToHexString operator to allow a maximum 200 character
-string to be produced.
-
-Fixed a problem in the internal string-to-buffer and buffer-to-buffer copy
-routine where the length of the resulting buffer was not truncated to the
-new size (if the target buffer already existed).
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

- Debug Version: 165.3K Code, 69.4K Data, 234.7K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Implemented the new ACPI 3.0 resource template macros - DWordSpace,
-ExtendedIO, ExtendedMemory, ExtendedSpace, QWordSpace, and WordSpace.
-Includes support in the disassembler.
-
-Implemented support for the new (ACPI 3.0) parameter to the Register macro,
-AccessSize.
-
-Fixed a problem where the _HE resource name for the Interrupt macro was
-referencing bit 0 instead of bit 1.
-
-Implemented check for maximum 255 interrupts in the Interrupt macro.
-
-Fixed a problem with the predefined resource descriptor names where
-incorrect AML code was generated if the offset within the resource buffer
-was 0 or 1. The optimizer shortened the AML code to a single byte opcode
-but did not update the surrounding package lengths.
-
-Changes to the Dma macro: All channels within the channel list must be in
-the range 0-7. Maximum 8 channels can be specified. BusMaster operand is
-optional (default is BusMaster).
-
-Implemented check for maximum 7 data bytes for the VendorShort macro.
-
-The ReadWrite parameter is now optional for the Memory32 and similar macros.
-
-----------------------------------------
-03 December 2004. Summary of changes for version 20041203:
-
-1) ACPI CA Core Subsystem:
-
-The low-level field insertion/extraction code (exfldio) has been completely
-rewritten to eliminate unnecessary complexity, bugs, and boundary
-conditions.
-
-Fixed a problem in the ToInteger, ToBuffer, ToHexString, and ToDecimalString
-operators where the input operand could be inadvertently deleted if no
-conversion was necessary (e.g., if the input to ToInteger was an Integer
-object.)
-
-Fixed a problem with the ToDecimalString and ToHexString where an incorrect
-exception code was returned if the resulting string would be > 200 chars.
-AE_STRING_LIMIT is now returned.
-
-Fixed a problem with the Concatenate operator where AE_OK was always
-returned, even if the operation failed.
-
-Fixed a problem in oswinxf (used by AcpiExec and iASL) to allow > 128
-semaphores to be allocated.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-
-
-2) iASL Compiler/Disassembler:
-
-Fixed typechecking for the ObjectType and SizeOf operators. Problem was
-recently introduced in 20041119.
-
-Fixed a problem with the ToUUID macro where the upper nybble of each buffer
-byte was inadvertently set to zero.
-
-----------------------------------------
-19 November 2004. Summary of changes for version 20041119:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem in the internal ConvertToInteger routine where new integers
-were not truncated to 32 bits for 32-bit ACPI tables. This routine converts
-buffers and strings to integers.
-
-Implemented support to store a value to an Index() on a String object. This
-is an ACPI 2.0 feature that had not yet been implemented.
-
-Implemented new behavior for storing objects to individual package elements
-(via the Index() operator). The previous behavior was to invoke the implicit
-conversion rules if an object was already present at the index. The new
-behavior is to simply delete any existing object and directly store the new
-object. Although the ACPI specification seems unclear on this subject, other
-ACPI implementations behave in this manner. (This is the root of the
-AE_BAD_HEX_CONSTANT issue.)
-
-Modified the RSDP memory scan mechanism to support the extended checksum for
-ACPI 2.0 (and above) RSDPs. Note that the search continues until a valid
-RSDP signature is found with a valid checksum.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-
-2) iASL Compiler/Disassembler:
-
-Fixed a missing semicolon in the aslcompiler.y file.
-
-----------------------------------------
-05 November 2004. Summary of changes for version 20041105:
-
-1) ACPI CA Core Subsystem:
-
-Implemented support for FADT revision 2. This was an interim table (between
-ACPI 1.0 and ACPI 2.0) that adds support for the FADT reset register.
-
-Implemented optional support to allow uninitialized LocalX and ArgX
-variables in a control method. The variables are initialized to an Integer
-object with a value of zero. This support is enabled by setting the
-AcpiGbl_EnableInterpreterSlack flag to TRUE.
-
-Implemented support for Integer objects for the SizeOf operator. Either 4
-or 8 is returned, depending on the current integer size (32-bit or 64-bit,
-depending on the parent table revision).
-
-Fixed a problem in the implementation of the SizeOf and ObjectType operators
-where the operand was resolved to a value too early, causing incorrect
-return values for some objects.
-
-Fixed some possible memory leaks during exceptional conditions.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-
-2) iASL Compiler/Disassembler:
-
-Implemented support for all ACPI 3.0 reserved names and methods.
-
-Implemented all ACPI 3.0 grammar elements in the front-end, including
-support for semicolons.
-
-Implemented the ACPI 3.0 Function() and ToUUID() macros
-
-Fixed a problem in the disassembler where a Scope() operator would not be
-emitted properly if the target of the scope was in another table.
-
-----------------------------------------
-15 October 2004. Summary of changes for version 20041015:
-
-Note: ACPI CA is currently undergoing an in-depth and complete formal
-evaluation to test/verify the following areas. Other suggestions are
-welcome. This will result in an increase in the frequency of releases and
-the number of bug fixes in the next few months.
- - Functional tests for all ASL/AML operators
- - All implicit/explicit type conversions
- - Bit fields and operation regions
- - 64-bit math support and 32-bit-only "truncated" math support
- - Exceptional conditions, both compiler and interpreter
- - Dynamic object deletion and memory leaks
- - ACPI 3.0 support when implemented
- - External interfaces to the ACPI subsystem
-
-
-1) ACPI CA Core Subsystem:
-
-Fixed two alignment issues on 64-bit platforms - within debug statements in
-AcpiEvGpeDetect and AcpiEvCreateGpeBlock. Removed references to the Address
-field within the non-aligned ACPI generic address structure.
-
-Fixed a problem in the Increment and Decrement operators where incorrect
-operand resolution could result in the inadvertent modification of the
-original integer when the integer is passed into another method as an
-argument and the arg is then incremented/decremented.
-
-Fixed a problem in the FromBCD operator where the upper 32-bits of a 64-bit
-BCD number were truncated during conversion.
-
-Fixed a problem in the ToDecimal operator where the length of the resulting
-string could be set incorrectly too long if the input operand was a Buffer
-object.
-
-Fixed a problem in the Logical operators (LLess, etc.) where a NULL byte (0)
-within a buffer would prematurely terminate a compare between buffer
-objects.
-
-Added a check for string overflow (>200 characters as per the ACPI
-specification) during the Concatenate operator with two string operands.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the

-2) iASL Compiler/Disassembler:
-
-Allow the use of the ObjectType operator on uninitialized Locals and Args
-(returns 0 as per the ACPI specification).
-
-Fixed a problem where the compiler would fault if there was a syntax error
-in the FieldName of all of the various CreateXXXField operators.
-
-Disallow the use of lower case letters within the EISAID macro, as per the
-ACPI specification. All EISAID strings must be of the form "UUUNNNN" Where
-U is an uppercase letter and N is a hex digit.

-----------------------------------------
-06 October 2004. Summary of changes for version 20041006:
-
-1) ACPI CA Core Subsystem:
-
-Implemented support for the ACPI 3.0 Timer operator. This ASL function
-implements a 64-bit timer with 100 nanosecond granularity.
-
-Defined a new OSL interface, AcpiOsGetTimer. This interface is used to
-implement the ACPI 3.0 Timer operator. This allows the host OS to implement
-the timer with the best clock available. Also, it keeps the core subsystem
-out of the clock handling business, since the host OS (usually) performs
-this function.
-
-Fixed an alignment issue on 64-bit platforms. The HwLowLevelRead(Write)
-functions use a 64-bit address which is part of the packed ACPI Generic
-Address Structure. Since the structure is non-aligned, the alignment macros
-are now used to extract the address to a local variable before use.
-
-Fixed a problem where the ToInteger operator assumed all input strings were
-hexadecimal. The operator now handles both decimal strings and hex strings
-(prefixed with "0x").
-
-Fixed a problem where the string length in the string object created as a
-result of the internal ConvertToString procedure could be incorrect. This
-potentially affected all implicit conversions and also the ToDecimalString
-and ToHexString operators.
-
-Fixed two problems in the ToString operator. If the length parameter was
-zero, an incorrect string object was created and the value of the input
-length parameter was inadvertently changed from zero to Ones.
-
-Fixed a problem where the optional ResourceSource string in the ExtendedIRQ
-resource macro was ignored.
-
-Simplified the interfaces to the internal division functions, reducing code
-size and complexity.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-
-2) iASL Compiler/Disassembler:
-
-Implemented support for the ACPI 3.0 Timer operator.
-
-Fixed a problem where the Default() operator was inadvertently ignored in a
-Switch/Case block. This was a problem in the translation of the Switch
-statement to If...Else pairs.
-
-Added support to allow a standalone Return operator, with no parentheses (or
-operands).
-
-Fixed a problem with code generation for the ElseIf operator where the
-translated Else...If parse tree was improperly constructed leading to the
-loss of some code.
-
-----------------------------------------
-22 September 2004. Summary of changes for version 20040922:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem with the implementation of the LNot() operator where "Ones"
-was not returned for the TRUE case. Changed the code to return Ones instead
-of (!Arg) which was usually 1. This change affects iASL constant folding for
-this operator also.
-
-Fixed a problem in AcpiUtInitializeBuffer where an existing buffer was not
-initialized properly -- Now zero the entire buffer in this case where the
-buffer already exists.
-
-Changed the interface to AcpiOsSleep from (UINT32 Seconds, UINT32
-Milliseconds) to simply (ACPI_INTEGER Milliseconds). This simplifies all
-related code considerably. This will require changes/updates to all OS
-interface layers (OSLs.)
-
-Implemented a new external interface, AcpiInstallExceptionHandler, to allow
-a system exception handler to be installed. This handler is invoked upon any
-run-time exception that occurs during control method execution.
-
-Added support for the DSDT in AcpiTbFindTable. This allows the
-DataTableRegion() operator to access the local copy of the DSDT.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

- Debug Version: 164.5K Code, 68.3K Data, 232.8K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a problem with constant folding and the LNot operator. LNot was
-returning 1 in the TRUE case, not Ones as per the ACPI specification. This
-could result in the generation of an incorrect folded/reduced constant.
-
-End-Of-File is now allowed within a "//"-style comment. A parse error no
-longer occurs if such a comment is at the very end of the input ASL source
-file.
-
-Implemented the "-r" option to override the Revision in the table header.
-The initial use of this option will be to simplify the evaluation of the AML
-interpreter by allowing a single ASL source module to be compiled for either
-32-bit or 64-bit integers.
-
-
-----------------------------------------
-27 August 2004. Summary of changes for version 20040827:
-
-1) ACPI CA Core Subsystem:
-
-- Implemented support for implicit object conversion in the non-numeric
-logical operators (LEqual, LGreater, LGreaterEqual, LLess, LLessEqual, and
-LNotEqual.) Any combination of Integers/Strings/Buffers may now be used;
-the second operand is implicitly converted on the fly to match the type of
-the first operand. For example:
-
- LEqual (Source1, Source2)
-
-Source1 and Source2 must each evaluate to an integer, a string, or a buffer.
-The data type of Source1 dictates the required type of Source2. Source2 is
-implicitly converted if necessary to match the type of Source1.
-
-- Updated and corrected the behavior of the string conversion support. The
-rules concerning conversion of buffers to strings (according to the ACPI
-specification) are as follows:
-
-ToDecimalString - explicit byte-wise conversion of buffer to string of
-decimal values (0-255) separated by commas. ToHexString - explicit byte-wise
-conversion of buffer to string of hex values (0-FF) separated by commas.
-ToString - explicit byte-wise conversion of buffer to string. Byte-by-byte
-copy with no transform except NULL terminated. Any other implicit buffer-to-
-string conversion - byte-wise conversion of buffer to string of hex values
-(0-FF) separated by spaces.
-
-- Fixed typo in definition of AcpiGbl_EnableInterpreterSlack.
-
-- Fixed a problem in AcpiNsGetPathnameLength where the returned length was
-one byte too short in the case of a node in the root scope. This could
-cause a fault during debug output.
-
-- Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-
-----------------------------------------
-16 August 2004. Summary of changes for version 20040816:
-
-1) ACPI CA Core Subsystem:
-
-Designed and implemented support within the AML interpreter for the so-
-called "implicit return". This support returns the result of the last ASL
-operation within a control method, in the absence of an explicit Return()
-operator. A few machines depend on this behavior, even though it is not
-explicitly supported by the ASL language. It is optional support that can
-be enabled at runtime via the AcpiGbl_EnableInterpreterSlack flag.
-
-Removed support for the PCI_Config address space from the internal low level
-hardware interfaces (AcpiHwLowLevelRead and AcpiHwLowLevelWrite). This
-support was not used internally, and would not work correctly anyway because
-the PCI bus number and segment number were not supported. There are
-separate interfaces for PCI configuration space access because of the unique
-interface.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.
-

- Non-Debug Version: 77.9K Code, 11.5K Data, 89.4K Total
- Debug Version: 164.1K Code, 68.3K Data, 232.4K Total
-
-
-2) iASL Compiler/Disassembler:
-
-Fixed a problem where constants in ASL expressions at the root level (not
-within a control method) could be inadvertently truncated during code
-generation. This problem was introduced in the 20040715 release.
-
-
-----------------------------------------
-15 July 2004. Summary of changes for version 20040715:
-
-1) ACPI CA Core Subsystem:
-
-Restructured the internal HW GPE interfaces to pass/track the current state
-of interrupts (enabled/disabled) in order to avoid possible deadlock and
-increase flexibility of the interfaces.
-
-Implemented a "lexicographical compare" for String and Buffer objects within
-the logical operators -- LGreater, LLess, LGreaterEqual, and LLessEqual --
-as per further clarification to the ACPI specification. Behavior is similar
-to C library "strcmp".
-
-Completed a major reduction in CPU stack use for the AcpiGetFirmwareTable
-external function. In the 32-bit non-debug case, the stack use has been
-reduced from 168 bytes to 32 bytes.
-
-Deployed a new run-time configuration flag, AcpiGbl_EnableInterpreterSlack,
-whose purpose is to allow the AML interpreter to forgive certain bad AML
-constructs. Default setting is FALSE.
-
-Implemented the first use of AcpiGbl_EnableInterpreterSlack in the Field IO
-support code. If enabled, it allows field access to go beyond the end of a
-region definition if the field is within the region length rounded up to the
-next access width boundary (a common coding error.)
-
-Renamed OSD_HANDLER to ACPI_OSD_HANDLER, and OSD_EXECUTION_CALLBACK to
-ACPI_OSD_EXEC_CALLBACK for consistency with other ACPI symbols. Also, these
-symbols are lowercased by the latest version of the AcpiSrc tool.
-
-The prototypes for the PCI interfaces in acpiosxf.h have been updated to
-rename "Register" to simply "Reg" to prevent certain compilers from
-complaining.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-
-
-2) iASL Compiler/Disassembler:
-
-Implemented full support for Package objects within the Case() operator.
-Note: The Break() operator is currently not supported within Case blocks
-(TermLists) as there is some question about backward compatibility with ACPI
-1.0 interpreters.
-
-
-Fixed a problem where complex terms were not supported properly within the
-Switch() operator.
-
-Eliminated extraneous warning for compiler-emitted reserved names of the
-form "_T_x". (Used in Switch/Case operators.)
-
-Eliminated optimization messages for "_T_x" objects and small constants
-within the DefinitionBlock operator.
-
-
-----------------------------------------
-15 June 2004. Summary of changes for version 20040615:
-
-1) ACPI CA Core Subsystem:
-
-Implemented support for Buffer and String objects (as per ACPI 2.0) for the
-following ASL operators: LEqual, LGreater, LLess, LGreaterEqual, and
-LLessEqual.
-
-All directory names in the entire source package are lower case, as they
-were in earlier releases.
-
-Implemented "Disassemble" command in the AML debugger that will disassemble
-a single control method.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include

-
-All directory names in the entire source package are lower case, as they
-were in earlier releases.
-
-Fixed a fault when using the -g or -d<nofilename> options if the FADT was
-not found.
-
-Fixed an issue with the Windows version of the compiler where later versions
-of Windows place the FADT in the registry under the name "FADT" and not
-"FACP" as earlier versions did. This applies when using the -g or -
-d<nofilename> options. The compiler now looks for both strings as
-necessary.
-
-Fixed a problem with compiler namepath optimization where a namepath within
-the Scope() operator could not be optimized if the namepath was a subpath of
-the current scope path.
-
-----------------------------------------
-27 May 2004. Summary of changes for version 20040527:
-
-1) ACPI CA Core Subsystem:
-
-Completed a new design and implementation for EBDA (Extended BIOS Data Area)
-support in the RSDP scan code. The original code improperly scanned for the
-EBDA by simply scanning from memory location 0 to 0x400. The correct method
-is to first obtain the EBDA pointer from within the BIOS data area, then
-scan 1K of memory starting at the EBDA pointer. There appear to be few if
-any machines that place the RSDP in the EBDA, however.
-
-Integrated a fix for a possible fault during evaluation of BufferField
-arguments. Obsolete code that was causing the problem was removed.
-
-Found and fixed a problem in the Field Support Code where data could be
-corrupted on a bit field read that starts on an aligned boundary but does
-not end on an aligned boundary. Merged the read/write "datum length"
-calculation code into a common procedure.
-
-Rolled in a couple of changes to the FreeBSD-specific header.
-
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and

-2) iASL Compiler/Disassembler:

-64-bit constant.
-
-----------------------------------------
-14 May 2004. Summary of changes for version 20040514:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem where hardware GPE enable bits sometimes not set properly
-during and after GPE method execution. Result of 04/27 changes.
-
-Removed extra "clear all GPEs" when sleeping/waking.
-
-Removed AcpiHwEnableGpe and AcpiHwDisableGpe, replaced by the single
-AcpiHwWriteGpeEnableReg. Changed a couple of calls to the functions above to
-the new AcpiEv* calls as appropriate.
-
-ACPI_OS_NAME was removed from the OS-specific headers. The default name is
-now "Microsoft Windows NT" for maximum compatibility. However this can be
-changed by modifying the acconfig.h file.
-
-Allow a single invocation of AcpiInstallNotifyHandler for a handler that
-traps both types of notifies (System, Device). Use ACPI_ALL_NOTIFY flag.
-
-Run _INI methods on ThermalZone objects. This is against the ACPI
-specification, but there is apparently ASL code in the field that has these
-_INI methods, and apparently "other" AML interpreters execute them.
-
-Performed a full 16/32/64 bit lint that resulted in some small changes.
-
-Added a sleep simulation command to the AML debugger to test sleep code.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and

-----------------------------------------
-27 April 2004. Summary of changes for version 20040427:
-
-1) ACPI CA Core Subsystem:
-
-Completed a major overhaul of the GPE handling within ACPI CA. There are
-now three types of GPEs: wake-only, runtime-only, and combination wake/run.
-The only GPEs allowed to be combination wake/run are for button-style
-devices such as a control-method power button, control-method sleep button,
-or a notebook lid switch. GPEs that have an _Lxx or _Exx method and are not
-referenced by any _PRW methods are marked for "runtime" and hardware
-enabled. Any GPE that is referenced by a _PRW method is marked for "wake"
-(and disabled at runtime). However, at sleep time, only those GPEs that
-have been specifically enabled for wake via the AcpiEnableGpe interface will
-actually be hardware enabled.
-
-A new external interface has been added, AcpiSetGpeType(), that is meant to
-be used by device drivers to force a GPE to a particular type. It will be
-especially useful for the drivers for the button devices mentioned above.
-
-Completed restructuring of the ACPI CA initialization sequence so that
-default operation region handlers are installed before GPEs are initialized
-and the _PRW methods are executed. This will prevent errors when the _PRW
-methods attempt to access system memory or I/O space.
-
-GPE enable/disable no longer reads the GPE enable register. We now keep the
-enable info for runtime and wake separate and in the GPE_EVENT_INFO. We
-thus no longer depend on the hardware to maintain these bits.
-
-Always clear the wake status and fixed/GPE status bits before sleep, even
-for state S5.
-
-Improved the AML debugger output for displaying the GPE blocks and their
-current status.
-
-Added new strings for the _OSI method, of the form "Windows 2001 SPx" where
-x = 0,1,2,3,4.
-
-Fixed a problem where the physical address was incorrectly calculated when
-the Load() operator was used to directly load from an Operation Region (vs.
-loading from a Field object.) Also added check for minimum table length for
-this case.
-
-Fix for multiple mutex acquisition. Restore original thread SyncLevel on
-mutex release.
-
-Added ACPI_VALID_SXDS flag to the AcpiGetObjectInfo interface for
-consistency with the other fields returned.
-
-Shrunk the ACPI_GPE_EVENT_INFO structure by 40%. There is one such
-structure for each GPE in the system, so the size of this structure is
-important.
-
-CPU stack requirement reduction: Cleaned up the method execution and object
-evaluation paths so that now a parameter structure is passed, instead of
-copying the various method parameters over and over again.
-
-In evregion.c: Correctly exit and reenter the interpreter region if and
-only if dispatching an operation region request to a user-installed handler.
-Do not exit/reenter when dispatching to a default handler (e.g., default
-system memory or I/O handlers)
-
-
-Notes for updating drivers for the new GPE support. The following changes
-must be made to ACPI-related device drivers that are attached to one or more
-GPEs: (This information will be added to the ACPI CA Programmer Reference.)
-
-1) AcpiInstallGpeHandler no longer automatically enables the GPE, you must
-explicitly call AcpiEnableGpe.
-2) There is a new interface called AcpiSetGpeType. This should be called
-before enabling the GPE. Also, this interface will automatically disable
-the GPE if it is currently enabled.
-3) AcpiEnableGpe no longer supports a GPE type flag.
-
-Specific drivers that must be changed:
-1) EC driver:
- AcpiInstallGpeHandler (NULL, GpeNum, ACPI_GPE_EDGE_TRIGGERED,
-AeGpeHandler, NULL);
- AcpiSetGpeType (NULL, GpeNum, ACPI_GPE_TYPE_RUNTIME);
- AcpiEnableGpe (NULL, GpeNum, ACPI_NOT_ISR);
-
-2) Button Drivers (Power, Lid, Sleep):
-Run _PRW method under parent device
-If _PRW exists: /* This is a control-method button */
- Extract GPE number and possibly GpeDevice
- AcpiSetGpeType (GpeDevice, GpeNum, ACPI_GPE_TYPE_WAKE_RUN);
- AcpiEnableGpe (GpeDevice, GpeNum, ACPI_NOT_ISR);
-
-For all other devices that have _PRWs, we automatically set the GPE type to
-ACPI_GPE_TYPE_WAKE, but the GPE is NOT automatically (wake) enabled. This
-must be done on a selective basis, usually requiring some kind of user app
-to allow the user to pick the wake devices.
-
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-----------------------------------------
-02 April 2004. Summary of changes for version 20040402:
-
-1) ACPI CA Core Subsystem:
-
-Fixed an interpreter problem where an indirect store through an ArgX
-parameter was incorrectly applying the "implicit conversion rules" during
-the store. From the ACPI specification: "If the target is a method local or
-argument (LocalX or ArgX), no conversion is performed and the result is
-stored directly to the target". The new behavior is to disable implicit
-conversion during ALL stores to an ArgX.
-
-Changed the behavior of the _PRW method scan to ignore any and all errors
-returned by a given _PRW. This prevents the scan from aborting from the
-failure of any single _PRW.
-
-Moved the runtime configuration parameters from the global init procedure to
-static variables in acglobal.h. This will allow the host to override the
-default values easily.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-
-2) iASL Compiler/Disassembler:
-
-iASL now fully disassembles SSDTs. However, External() statements are not
-generated automatically for unresolved symbols at this time. This is a
-planned feature for future implementation.
-
-Fixed a scoping problem in the disassembler that occurs when the type of the
-target of a Scope() operator is overridden. This problem caused an
-incorrectly nested internal namespace to be constructed.
-
-Any warnings or errors that are emitted during disassembly are now commented
-out automatically so that the resulting file can be recompiled without any
-hand editing.
-
-----------------------------------------
-26 March 2004. Summary of changes for version 20040326:
-
-1) ACPI CA Core Subsystem:
-
-Implemented support for "wake" GPEs via interaction between GPEs and the
-_PRW methods. Every GPE that is pointed to by one or more _PRWs is
-identified as a WAKE GPE and by default will no longer be enabled at
-runtime. Previously, we were blindly enabling all GPEs with a corresponding
-_Lxx or _Exx method - but most of these turn out to be WAKE GPEs anyway. We
-believe this has been the cause of thousands of "spurious" GPEs on some
-systems.
-
-This new GPE behavior is can be reverted to the original behavior (enable
-ALL GPEs at runtime) via a runtime flag.
-
-Fixed a problem where aliased control methods could not access objects
-properly. The proper scope within the namespace was not initialized
-(transferred to the target of the aliased method) before executing the
-target method.
-
-Fixed a potential race condition on internal object deletion on the return
-object in AcpiEvaluateObject.
-
-Integrated a fix for resource descriptors where both _MEM and _MTP were
-being extracted instead of just _MEM. (i.e. bitmask was incorrectly too
-wide, 0x0F instead of 0x03.)
-
-Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName, preventing a
-fault in some cases.
-
-Updated Notify() values for debug statements in evmisc.c
-
-Return proper status from AcpiUtMutexInitialize, not just simply AE_OK.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-----------------------------------------
-11 March 2004. Summary of changes for version 20040311:
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem where errors occurring during the parse phase of control
-method execution did not abort cleanly. For example, objects created and
-installed in the namespace were not deleted. This caused all subsequent
-invocations of the method to return the AE_ALREADY_EXISTS exception.
-
-Implemented a mechanism to force a control method to "Serialized" execution
-if the method attempts to create namespace objects. (The root of the
-AE_ALREADY_EXISTS problem.)
-
-Implemented support for the predefined _OSI "internal" control method.
-Initial supported strings are "Linux", "Windows 2000", "Windows 2001", and
-"Windows 2001.1", and can be easily upgraded for new strings as necessary.
-This feature will allow "other" operating systems to execute the fully
-tested, "Windows" code path through the ASL code
-
-Global Lock Support: Now allows multiple acquires and releases with any
-internal thread. Removed concept of "owning thread" for this special mutex.
-
-Fixed two functions that were inappropriately declaring large objects on the
-CPU stack: PsParseLoop, NsEvaluateRelative. Reduces the stack usage during
-method execution considerably.
-
-Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the
-S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT.
-
-Fixed a problem where AcpiEvGpeDetect would fault if there were no GPEs
-defined on the machine.
-
-Implemented two runtime options: One to force all control method execution
-to "Serialized" to mimic Windows behavior, another to disable _OSI support
-if it causes problems on a given machine.
-
-Code and Data Size: Current and previous core subsystem library sizes are
-shown below. These are the code and data sizes for the acpica.lib produced
-by the Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code includes the
-debug output trace mechanism and has a much larger code and data size. Note
-that these values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.

-fault.
-
-----------------------------------------
-20 February 2004. Summary of changes for version 20040220:
-
-
-1) ACPI CA Core Subsystem:

-GetObjectInfo interface.
-
-Fixed calls to _SST method to pass the correct arguments.
-
-Added a call to _SST on wake to restore to "working" state.
-
-Check for End-Of-Buffer failure case in the WalkResources interface.
-
-Integrated fix for 64-bit alignment issue in acglobal.h by moving two
-structures to the beginning of the file.
-
-After wake, clear GPE status register(s) before enabling GPEs.
-
-After wake, clear/enable power button. (Perhaps we should clear/enable all
-fixed events upon wake.)
-
-Fixed a couple of possible memory leaks in the Namespace manager.
-
-Integrated latest acnetbsd.h file.
-
-----------------------------------------
-11 February 2004. Summary of changes for version 20040211:
-
-
-1) ACPI CA Core Subsystem:
-
-Completed investigation and implementation of the call-by-reference
-mechanism for control method arguments.
-
-Fixed a problem where a store of an object into an indexed package could
-fail if the store occurs within a different method than the method that
-created the package.
-
-Fixed a problem where the ToDecimal operator could return incorrect results.
-
-Fixed a problem where the CopyObject operator could fail on some of the more
-obscure objects (e.g., Reference objects.)
-
-Improved the output of the Debug object to display buffer, package, and
-index objects.
-
-Fixed a problem where constructs of the form "RefOf (ArgX)" did not return
-the expected result.
-
-Added permanent ACPI_REPORT_ERROR macros for all instances of the
-ACPI_AML_INTERNAL exception.
-
-Integrated latest version of acfreebsd.h
-
-----------------------------------------
-16 January 2004. Summary of changes for version 20040116:
-
-The purpose of this release is primarily to update the copyright years in
-each module, thus causing a huge number of diffs. There are a few small
-functional changes, however.
-
-1) ACPI CA Core Subsystem:
-
-Improved error messages when there is a problem finding one or more of the
-required base ACPI tables
-
-Reintroduced the definition of APIC_HEADER in actbl.h
-
-Changed definition of MADT_ADDRESS_OVERRIDE to 64 bits (actbl.h)
-
-Removed extraneous reference to NewObj in dsmthdat.c
-
-2) iASL compiler
-
-Fixed a problem introduced in December that disabled the correct disassembly
-of Resource Templates
-
-
-----------------------------------------
-03 December 2003. Summary of changes for version 20031203:
-
-1) ACPI CA Core Subsystem:
-
-Changed the initialization of Operation Regions during subsystem
-init to perform two entire walks of the ACPI namespace; The first
-to initialize the regions themselves, the second to execute the
-_REG methods. This fixed some interdependencies across _REG
-methods found on some machines.
-
-Fixed a problem where a Store(Local0, Local1) could simply update
-the object reference count, and not create a new copy of the
-object if the Local1 is uninitialized.
-
-Implemented support for the _SST reserved method during sleep
-transitions.
-
-Implemented support to clear the SLP_TYP and SLP_EN bits when
-waking up, this is apparently required by some machines.
-
-When sleeping, clear the wake status only if SleepState is not S5.
-
-Fixed a problem in AcpiRsExtendedIrqResource() where an incorrect
-pointer arithmetic advanced a string pointer too far.
-
-Fixed a problem in AcpiTbGetTablePtr() where a garbage pointer
-could be returned if the requested table has not been loaded.
-
-Within the support for IRQ resources, restructured the handling of
-the active and edge/level bits.
-
-Fixed a few problems in AcpiPsxExecute() where memory could be
-leaked under certain error conditions.
-
-Improved error messages for the cases where the ACPI mode could
-not be entered.
-
-Code and Data Size: Current and previous core subsystem library
-sizes are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
-these values do not include any ACPI driver or OSPM code. The
-debug version of the code includes the debug output trace
-mechanism and has a much larger code and data size. Note that
-these values will vary depending on the efficiency of the compiler
-and the compiler options used during generation.

- Non-Debug Version: 74.8K Code, 10.1K Data, 84.9K Total
- Debug Version: 158.7K Code, 65.1K Data, 223.8K Total
-
-2) iASL Compiler/Disassembler:
-
-Implemented a fix for the iASL disassembler where a bad index was
-generated. This was most noticeable on 64-bit platforms
-
-
-----------------------------------------
-29 October 2003. Summary of changes for version 20031029:
-
-1) ACPI CA Core Subsystem:
-
-
-Fixed a problem where a level-triggered GPE with an associated
-_Lxx control method was incorrectly cleared twice.
-
-Fixed a problem with the Field support code where an access can
-occur beyond the end-of-region if the field is non-aligned but
-extends to the very end of the parent region (resulted in an
-AE_AML_REGION_LIMIT exception.)
-
-Fixed a problem with ACPI Fixed Events where an RT Clock handler
-would not get invoked on an RTC event. The RTC event bitmasks for
-the PM1 registers were not being initialized properly.
-
-Implemented support for executing _STA and _INI methods for
-Processor objects. Although this is currently not part of the
-ACPI specification, there is existing ASL code that depends on the
-init-time execution of these methods.
-
-Implemented and deployed a GetDescriptorName function to decode
-the various types of internal descriptors. Guards against null
-descriptors during debug output also.
-
-Implemented and deployed a GetNodeName function to extract the 4-
-character namespace node name. This function simplifies the debug
-and error output, as well as guarding against null pointers during
-output.
-
-Implemented and deployed the ACPI_FORMAT_UINT64 helper macro to
-simplify the debug and error output of 64-bit integers. This
-macro replaces the HIDWORD and LODWORD macros for dumping these
-integers.
-
-Updated the implementation of the Stall() operator to only call
-AcpiOsStall(), and also return an error if the operand is larger
-than 255. This preserves the required behavior of not
-relinquishing the processor, as would happen if AcpiOsSleep() was
-called for "long stalls".
-
-Constructs of the form "Store(LocalX,LocalX)" where LocalX is not
-initialized are now treated as NOOPs.
-
-Cleaned up a handful of warnings during 64-bit generation.
-
-Fixed a reported error where and incorrect GPE number was passed
-to the GPE dispatch handler. This value is only used for error
-output, however. Used this opportunity to clean up and streamline
-the GPE dispatch code.
-
-Code and Data Size: Current and previous core subsystem library
-sizes are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
-these values do not include any ACPI driver or OSPM code. The
-
-debug version of the code includes the debug output trace
-mechanism and has a much larger code and data size. Note that
-these values will vary depending on the efficiency of the compiler
-and the compiler options used during generation.

-
-
-2) iASL Compiler/Disassembler:
-
-Updated the iASL compiler to return an error if the operand to the
-Stall() operator is larger than 255.
-
-
-----------------------------------------
-02 October 2003. Summary of changes for version 20031002:
-
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem with Index Fields where the index was not
-incremented for fields that require multiple writes to the
-index/data registers (Fields that are wider than the data
-register.)
-
-Fixed a problem with all Field objects where a write could go
-beyond the end-of-field if the field was larger than the access
-granularity and therefore required multiple writes to complete the
-request. An extra write beyond the end of the field could happen
-inadvertently.
-
-Fixed a problem with Index Fields where a BUFFER_OVERFLOW error
-would incorrectly be returned if the width of the Data Register
-was larger than the specified field access width.
-
-Completed fixes for LoadTable() and Unload() and verified their
-operation. Implemented full support for the "DdbHandle" object
-throughout the ACPI CA subsystem.
-
-Implemented full support for the MADT and ECDT tables in the ACPI
-CA header files. Even though these tables are not directly
-consumed by ACPI CA, the header definitions are useful for ACPI
-device drivers.
-
-Integrated resource descriptor fixes posted to the Linux ACPI
-list. This included checks for minimum descriptor length, and
-support for trailing NULL strings within descriptors that have
-optional string elements.
-
-Code and Data Size: Current and previous core subsystem library
-sizes are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
-these values do not include any ACPI driver or OSPM code. The
-debug version of the code includes the debug output trace
-mechanism and has a much larger code and data size. Note that
-these values will vary depending on the efficiency of the compiler
-and the compiler options used during generation.

- Debug Version: 157.9K Code, 64.8K Data, 222.7K Total
-
-
-2) iASL Compiler:
-
-Implemented detection of non-ASCII characters within the input
-source ASL file. This catches attempts to compile binary (AML)
-files early in the compile, with an informative error message.
-
-Fixed a problem where the disassembler would fault if the output
-filename could not be generated or if the output file could not be
-opened.
-
-----------------------------------------
-18 September 2003. Summary of changes for version 20030918:
-
-
-1) ACPI CA Core Subsystem:
-
-Found and fixed a longstanding problem with the late execution of
-the various deferred AML opcodes (such as Operation Regions,
-Buffer Fields, Buffers, and Packages). If the name string
-specified for the name of the new object placed the object in a
-scope other than the current scope, the initialization/execution
-of the opcode failed. The solution to this problem was to
-implement a mechanism where the late execution of such opcodes
-does not attempt to lookup/create the name a second time in an
-incorrect scope. This fixes the "region size computed
-incorrectly" problem.
-
-Fixed a call to AcpiHwRegisterWrite in hwregs.c that was causing a
-Global Lock AE_BAD_PARAMETER error.
-
-Fixed several 64-bit issues with prototypes, casting and data
-types.
-
-Removed duplicate prototype from acdisasm.h
-
-Fixed an issue involving EC Operation Region Detach (Shaohua Li)
-
-Code and Data Size: Current and previous core subsystem library
-sizes are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
-these values do not include any ACPI driver or OSPM code. The
-debug version of the code includes the debug output trace
-mechanism and has a much larger code and data size. Note that
-these values will vary depending on the efficiency of the compiler
-and the compiler options used during generation.

-
-
-2) Linux:
-
-Fixed the AcpiOsSleep implementation in osunixxf.c to pass the
-correct sleep time in seconds.
-
-----------------------------------------
-14 July 2003. Summary of changes for version 20030619:
-
-1) ACPI CA Core Subsystem:
-
-Parse SSDTs in order discovered, as opposed to reverse order
-(Hrvoje Habjanic)
-
-Fixes from FreeBSD and NetBSD. (Frank van der Linden, Thomas
-Klausner,
- Nate Lawson)
-
-
-2) Linux:
-
-Dynamically allocate SDT list (suggested by Andi Kleen)
-
-proc function return value cleanups (Andi Kleen)
-
-Correctly handle NMI watchdog during long stalls (Andrew Morton)
-
-Make it so acpismp=force works (reported by Andrew Morton)
-
-
-----------------------------------------
-19 June 2003. Summary of changes for version 20030619:
-
-1) ACPI CA Core Subsystem:
-
-Fix To/FromBCD, eliminating the need for an arch-specific #define.
-
-Do not acquire a semaphore in the S5 shutdown path.
-
-Fix ex_digits_needed for 0. (Takayoshi Kochi)
-
-Fix sleep/stall code reversal. (Andi Kleen)
-
-Revert a change having to do with control method calling
-semantics.
-
-2) Linux:
-
-acpiphp update (Takayoshi Kochi)
-
-Export acpi_disabled for sonypi (Stelian Pop)
-
-Mention acpismp=force in config help
-
-Re-add acpitable.c and acpismp=force. This improves backwards
-
-compatibility and also cleans up the code to a significant degree.
-
-Add ASUS Value-add driver (Karol Kozimor and Julien Lerouge)
-
-----------------------------------------
-22 May 2003. Summary of changes for version 20030522:
-
-1) ACPI CA Core Subsystem:
-
-Found and fixed a reported problem where an AE_NOT_FOUND error
-occurred occasionally during _BST evaluation. This turned out to
-be an Owner ID allocation issue where a called method did not get
-a new ID assigned to it. Eventually, (after 64k calls), the Owner
-ID UINT16 would wraparound so that the ID would be the same as the
-caller's and the called method would delete the caller's
-namespace.
-
-Implemented extended error reporting for control methods that are
-aborted due to a run-time exception. Output includes the exact
-AML instruction that caused the method abort, a dump of the method
-locals and arguments at the time of the abort, and a trace of all
-nested control method calls.
-
-Modified the interpreter to allow the creation of buffers of zero
-length from the AML code. Implemented new code to ensure that no
-attempt is made to actually allocate a memory buffer (of length
-zero) - instead, a simple buffer object with a NULL buffer pointer
-and length zero is created. A warning is no longer issued when
-the AML attempts to create a zero-length buffer.
-
-Implemented a workaround for the "leading asterisk issue" in
-_HIDs, _UIDs, and _CIDs in the AML interpreter. One leading
-asterisk is automatically removed if present in any HID, UID, or
-CID strings. The iASL compiler will still flag this asterisk as
-an error, however.
-
-Implemented full support for _CID methods that return a package of
-multiple CIDs (Compatible IDs). The AcpiGetObjectInfo() interface
-now additionally returns a device _CID list if present. This
-required a change to the external interface in order to pass an
-ACPI_BUFFER object as a parameter since the _CID list is of
-variable length.
-
-Fixed a problem with the new AE_SAME_HANDLER exception where
-handler initialization code did not know about this exception.
-
-Code and Data Size: Current and previous core subsystem library
-sizes are shown below. These are the code and data sizes for the
-acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
-these values do not include any ACPI driver or OSPM code. The
-debug version of the code includes the debug output trace
-mechanism and has a much larger code and data size. Note that
-these values will vary depending on the efficiency of the compiler
-and the compiler options used during generation.

- Debug Version: 156.9K Code, 64.2K Data, 221.1K Total
-
-
-2) Linux:
-
-Fixed a bug in which we would reinitialize the ACPI interrupt
-after it was already working, thus disabling all ACPI and the IRQs
-for any other device sharing the interrupt. (Thanks to Stian
-Jordet)
-
-Toshiba driver update (John Belmonte)
-
-Return only 0 or 1 for our interrupt handler status (Andrew
-Morton)
-
-
-3) iASL Compiler:
-
-Fixed a reported problem where multiple (nested) ElseIf()
-statements were not handled correctly by the compiler, resulting
-in incorrect warnings and incorrect AML code. This was a problem
-in both the ASL parser and the code generator.
-
-
-4) Documentation:
-
-Added changes to existing interfaces, new exception codes, and new
-text concerning reference count object management versus garbage
-collection.
-
-----------------------------------------
-09 May 2003. Summary of changes for version 20030509.
-
-
-1) ACPI CA Core Subsystem:
-
-Changed the subsystem initialization sequence to hold off
-installation of address space handlers until the hardware has been
-initialized and the system has entered ACPI mode. This is because
-the installation of space handlers can cause _REG methods to be
-run. Previously, the _REG methods could potentially be run before
-ACPI mode was enabled.
-
-Fixed some memory leak issues related to address space handler and
-notify handler installation. There were some problems with the
-reference count mechanism caused by the fact that the handler
-objects are shared across several namespace objects.
-
-Fixed a reported problem where reference counts within the
-namespace were not properly updated when named objects created by
-method execution were deleted.
-
-Fixed a reported problem where multiple SSDTs caused a deletion
-issue during subsystem termination. Restructured the table data
-structures to simplify the linked lists and the related code.
-
-Fixed a problem where the table ID associated with secondary
-tables (SSDTs) was not being propagated into the namespace objects
-created by those tables. This would only present a problem for
-tables that are unloaded at run-time, however.
-
-Updated AcpiOsReadable and AcpiOsWritable to use the ACPI_SIZE
-type as the length parameter (instead of UINT32).
-
-Solved a long-standing problem where an ALREADY_EXISTS error
-appears on various systems. This problem could happen when there
-are multiple PCI_Config operation regions under a single PCI root
-bus. This doesn't happen very frequently, but there are some
-systems that do this in the ASL.
-
-Fixed a reported problem where the internal DeleteNode function
-was incorrectly handling the case where a namespace node was the
-first in the parent's child list, and had additional peers (not
-the only child, but first in the list of children.)
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a much larger code and data size. Note that these values will
-vary depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-2) Linux:
-
-Allow ":" in OS override string (Ducrot Bruno)
-
-Kobject fix (Greg KH)
-
-
-3 iASL Compiler/Disassembler:
-
-Fixed a problem in the generation of the C source code files (AML
-is emitted in C source statements for BIOS inclusion) where the
-Ascii dump that appears within a C comment at the end of each line
-could cause a compile time error if the AML sequence happens to
-have an open comment or close comment sequence embedded.
-
-
-----------------------------------------
-24 April 2003. Summary of changes for version 20030424.
-
-
-1) ACPI CA Core Subsystem:
-
-Support for big-endian systems has been implemented. Most of the
-support has been invisibly added behind big-endian versions of the
-ACPI_MOVE_* macros.
-
-Fixed a problem in AcpiHwDisableGpeBlock() and
-AcpiHwClearGpeBlock() where an incorrect offset was passed to the
-low level hardware write routine. The offset parameter was
-actually eliminated from the low level read/write routines because
-they had become obsolete.
-
-Fixed a problem where a handler object was deleted twice during
-the removal of a fixed event handler.
-
-
-2) Linux:
-
-A fix for SMP systems with link devices was contributed by
-
-Compaq's Dan Zink.
-
-(2.5) Return whether we handled the interrupt in our IRQ handler.
-(Linux ISRs no longer return void, so we can propagate the handler
-return value from the ACPI CA core back to the OS.)
-
-
-
-3) Documentation:
-
-The ACPI CA Programmer Reference has been updated to reflect new
-interfaces and changes to existing interfaces.
-
-----------------------------------------
-28 March 2003. Summary of changes for version 20030328.
-
-1) ACPI CA Core Subsystem:
-
-The GPE Block Device support has been completed. New interfaces
-are AcpiInstallGpeBlock and AcpiRemoveGpeBlock. The Event
-interfaces (enable, disable, clear, getstatus) have been split
-into separate interfaces for Fixed Events and General Purpose
-Events (GPEs) in order to support GPE Block Devices properly.
-
-Fixed a problem where the error message "Failed to acquire
-semaphore" would appear during operations on the embedded
-controller (EC).
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a much larger code and data size. Note that these values will
-vary depending on the efficiency of the compiler and the compiler
-options used during generation.

-----------------------------------------
-28 February 2003. Summary of changes for version 20030228.
-
-
-1) ACPI CA Core Subsystem:
-
-The GPE handling and dispatch code has been completely overhauled
-in preparation for support of GPE Block Devices (ID ACPI0006).
-This affects internal data structures and code only; there should
-be no differences visible externally. One new file has been
-added, evgpeblk.c
-
-The FADT fields GPE0_BLK_LEN and GPE1_BLK_LEN are now the only
-fields that are used to determine the GPE block lengths. The
-REGISTER_BIT_WIDTH field of the X_GPEx_BLK extended address
-structures are ignored. This is per the ACPI specification but it
-isn't very clear. The full 256 Block 0/1 GPEs are now supported
-(the use of REGISTER_BIT_WIDTH limited the number of GPEs to 128).
-
-In the SCI interrupt handler, removed the read of the PM1_CONTROL
-register to look at the SCI_EN bit. On some machines, this read
-causes an SMI event and greatly slows down SCI events. (This may
-in fact be the cause of slow battery status response on some
-systems.)
-
-Fixed a problem where a store of a NULL string to a package object
-could cause the premature deletion of the object. This was seen
-during execution of the battery _BIF method on some systems,
-resulting in no battery data being returned.
-
-Added AcpiWalkResources interface to simplify parsing of resource
-lists.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a much larger code and data size. Note that these values will
-vary depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-3) iASL Compiler:

-
-Added support for the _PDC reserved name.
-
-
-----------------------------------------
-22 January 2003. Summary of changes for version 20030122.
-
-
-1) ACPI CA Core Subsystem:
-
-Added a check for constructs of the form: Store (Local0, Local0)
-where Local0 is not initialized. Apparently, some BIOS
-programmers believe that this is a NOOP. Since this store doesn't
-do anything anyway, the new prototype behavior will ignore this
-error. This is a case where we can relax the strict checking in
-the interpreter in the name of compatibility.
-
-
-2) Linux
-
-The AcpiSrc Source Conversion Utility has been released with the
-Linux package for the first time. This is the utility that is
-used to convert the ACPI CA base source code to the Linux version.
-
-(Both) Handle P_BLK lengths shorter than 6 more gracefully
-
-(Both) Move more headers to include/acpi, and delete an unused
-header.
-
-(Both) Move drivers/acpi/include directory to include/acpi
-
-(Both) Boot functions don't use cmdline, so don't pass it around
-
-(Both) Remove include of unused header (Adrian Bunk)
-
-(Both) acpiphp.h includes both linux/acpi.h and acpi_bus.h. Since
-the
-former now also includes the latter, acpiphp.h only needs the one,
-now.
-
-(2.5) Make it possible to select method of bios restoring after S3
-resume. [=> no more ugly ifdefs] (Pavel Machek)
-
-(2.5) Make proc write interfaces work (Pavel Machek)
-
-(2.5) Properly init/clean up in cpufreq/acpi (Dominik Brodowski)
-
-(2.5) Break out ACPI Perf code into its own module, under cpufreq
-(Dominik Brodowski)
-
-(2.4) S4BIOS support (Ducrot Bruno)
-
-(2.4) Fix acpiphp_glue.c for latest ACPI struct changes (Sergio
-Visinoni)
-
-
-3) iASL Compiler:
-
-Added support to disassemble SSDT and PSDTs.
-
-Implemented support to obtain SSDTs from the Windows registry if
-available.
-
-
-----------------------------------------
-09 January 2003. Summary of changes for version 20030109.
-
-1) ACPI CA Core Subsystem:
-
-Changed the behavior of the internal Buffer-to-String conversion
-function. The current ACPI specification states that the contents
-of the buffer are "converted to a string of two-character
-hexadecimal numbers, each separated by a space". Unfortunately,
-this definition is not backwards compatible with existing ACPI 1.0
-implementations (although the behavior was not defined in the ACPI
-1.0 specification). The new behavior simply copies data from the
-buffer to the string until a null character is found or the end of
-the buffer is reached. The new String object is always null
-terminated. This problem was seen during the generation of _BIF
-battery data where incorrect strings were returned for battery
-type, etc. This will also require an errata to the ACPI
-specification.
-
-Renamed all instances of NATIVE_UINT and NATIVE_INT to
-ACPI_NATIVE_UINT and ACPI_NATIVE_INT, respectively.
-
-Copyright in all module headers (both Linux and non-Linux) has be
-updated to 2003.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a much larger code and data size. Note that these values will
-vary depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-(2.5) Replace pr_debug (Randy Dunlap)
-
-(2.5) Remove usage of CPUFREQ_ALL_CPUS (Dominik Brodowski)
-
-(Both) Eliminate spawning of thread from timer callback, in favor
-of schedule_work()
-
-(Both) Show Lid status in /proc (Zdenek OGAR Skalak)
-
-(Both) Added define for Fixed Function HW region (Matthew Wilcox)
-
-(Both) Add missing statics to button.c (Pavel Machek)
-
-Several changes have been made to the source code translation
-utility that generates the Linux Code in order to make the code
-more "Linux-like":
-
-All typedefs on structs and unions have been removed in keeping
-with the Linux coding style.
-
-Removed the non-Linux SourceSafe module revision number from each
-module header.
-
-Completed major overhaul of symbols to be lowercased for linux.
-Doubled the number of symbols that are lowercased.
-
-Fixed a problem where identifiers within procedure headers and
-within quotes were not fully lower cased (they were left with a
-starting capital.)
-
-Some C macros whose only purpose is to allow the generation of 16-
-bit code are now completely removed in the Linux code, increasing
-readability and maintainability.
-
-----------------------------------------
-
-12 December 2002. Summary of changes for version 20021212.
-
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem where the creation of a zero-length AML Buffer
-would cause a fault.
-
-Fixed a problem where a Buffer object that pointed to a static AML
-buffer (in an ACPI table) could inadvertently be deleted, causing
-memory corruption.
-
-Fixed a problem where a user buffer (passed in to the external
-ACPI CA interfaces) could be overwritten if the buffer was too
-small to complete the operation, causing memory corruption.
-
-Fixed a problem in the Buffer-to-String conversion code where a
-string of length one was always returned, regardless of the size
-of the input Buffer object.
-
-Removed the NATIVE_CHAR data type across the entire source due to
-lack of need and lack of consistent use.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a much larger code and data size. Note that these values will
-vary depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-
-----------------------------------------
-05 December 2002. Summary of changes for version 20021205.
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem where a store to a String or Buffer object could
-cause corruption of the DSDT if the object type being stored was
-the same as the target object type and the length of the object
-being stored was equal to or smaller than the original (existing)
-target object. This was seen to cause corruption of battery _BIF
-buffers if the _BIF method modified the buffer on the fly.
-
-Fixed a problem where an internal error was generated if a control
-method invocation was used in an OperationRegion, Buffer, or
-Package declaration. This was caused by the deferred parsing of
-the control method and thus the deferred creation of the internal
-method object. The solution to this problem was to create the
-internal method object at the moment the method is encountered in
-the first pass - so that subsequent references to the method will
-able to obtain the required parameter count and thus properly
-parse the method invocation. This problem presented itself as an
-AE_AML_INTERNAL during the pass 1 parse phase during table load.
-
-Fixed a problem where the internal String object copy routine did
-not always allocate sufficient memory for the target String object
-and caused memory corruption. This problem was seen to cause
-"Allocation already present in list!" errors as memory allocation
-became corrupted.
-
-Implemented a new function for the evaluation of namespace objects
-that allows the specification of the allowable return object
-types. This simplifies a lot of code that checks for a return
-object of one or more specific objects returned from the
-evaluation (such as _STA, etc.) This may become and external
-function if it would be useful to ACPI-related drivers.
-
-Completed another round of prefixing #defines with "ACPI_" for
-clarity.
-
-Completed additional code restructuring to allow more modular
-linking for iASL compiler and AcpiExec. Several files were split
-creating new files. New files: nsparse.c dsinit.c evgpe.c
-
-Implemented an abort mechanism to terminate an executing control
-method via the AML debugger. This feature is useful for debugging
-control methods that depend (wait) for specific hardware
-responses.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a much larger code and data size. Note that these values will
-vary depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-
-2) iASL Compiler/Disassembler
-
-Fixed a compiler code generation problem for "Interrupt" Resource
-Descriptors. If specified in the ASL, the optional "Resource
-Source Index" and "Resource Source" fields were not inserted into
-the correct location within the AML resource descriptor, creating
-an invalid descriptor.
-
-Fixed a disassembler problem for "Interrupt" resource descriptors.
-The optional "Resource Source Index" and "Resource Source" fields
-were ignored.
-
-
-----------------------------------------
-22 November 2002. Summary of changes for version 20021122.
-
-
-1) ACPI CA Core Subsystem:
-
-Fixed a reported problem where an object stored to a Method Local
-or Arg was not copied to a new object during the store - the
-object pointer was simply copied to the Local/Arg. This caused
-all subsequent operations on the Local/Arg to also affect the
-original source of the store operation.
-
-Fixed a problem where a store operation to a Method Local or Arg
-was not completed properly if the Local/Arg contained a reference
-(from RefOf) to a named field. The general-purpose store-to-
-namespace-node code is now used so that this case is handled
-automatically.
-
-Fixed a problem where the internal object copy routine would cause
-a protection fault if the object being copied was a Package and
-contained either 1) a NULL package element or 2) a nested sub-
-package.
-
-Fixed a problem with the GPE initialization that resulted from an
-ambiguity in the ACPI specification. One section of the
-specification states that both the address and length of the GPE
-block must be zero if the block is not supported. Another section
-implies that only the address need be zero if the block is not
-supported. The code has been changed so that both the address and
-the length must be non-zero to indicate a valid GPE block (i.e.,
-if either the address or the length is zero, the GPE block is
-invalid.)
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a much larger code and data size. Note that these values will
-vary depending on the efficiency of the compiler and the compiler
-options used during generation.

- Debug Version: 152.9K Code, 63.3K Data, 216.2K Total
-
-
-2) Linux
-
-Cleaned up EC driver. Exported an external EC read/write
-interface. By going through this, other drivers (most notably
-sonypi) will be able to serialize access to the EC.
-
-
-3) iASL Compiler/Disassembler
-
-Implemented support to optionally generate include files for both
-ASM and C (the -i switch). This simplifies BIOS development by
-automatically creating include files that contain external
-declarations for the symbols that are created within the
-
-(optionally generated) ASM and C AML source files.
-
-
-----------------------------------------
-15 November 2002. Summary of changes for version 20021115.
-
-1) ACPI CA Core Subsystem:
-
-Fixed a memory leak problem where an error during resolution of
-
-method arguments during a method invocation from another method
-failed to cleanup properly by deleting all successfully resolved
-argument objects.
-
-Fixed a problem where the target of the Index() operator was not
-correctly constructed if the source object was a package. This
-problem has not been detected because the use of a target operand
-with Index() is very rare.
-
-Fixed a problem with the Index() operator where an attempt was
-made to delete the operand objects twice.
-
-Fixed a problem where an attempt was made to delete an operand
-twice during execution of the CondRefOf() operator if the target
-did not exist.
-
-Implemented the first of perhaps several internal create object
-functions that create and initialize a specific object type. This
-consolidates duplicated code wherever the object is created, thus
-shrinking the size of the subsystem.
-
-Implemented improved debug/error messages for errors that occur
-during nested method invocations. All executing method pathnames
-are displayed (with the error) as the call stack is unwound - thus
-simplifying debug.
-
-Fixed a problem introduced in the 10/02 release that caused
-premature deletion of a buffer object if a buffer was used as an
-ASL operand where an integer operand is required (Thus causing an
-implicit object conversion from Buffer to Integer.) The change in
-the 10/02 release was attempting to fix a memory leak (albeit
-incorrectly.)
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a much larger code and data size. Note that these values will
-vary depending on the efficiency of the compiler and the compiler
-options used during generation.

- Non-Debug Version: 71.3K Code, 9.0K Data, 80.3K Total
- Debug Version: 152.7K Code, 63.2K Data, 215.5K Total
-
-
-2) Linux
-
-Changed the implementation of the ACPI semaphores to use down()
-instead of down_interruptable(). It is important that the
-execution of ACPI control methods not be interrupted by signals.
-Methods must run to completion, or the system may be left in an
-unknown/unstable state.
-
-Fixed a compilation error when CONFIG_SOFTWARE_SUSPEND is not set.
-(Shawn Starr)
-
-
-3) iASL Compiler/Disassembler
-
-
-Changed the default location of output files. All output files
-are now placed in the current directory by default instead of in
-the directory of the source file. This change may affect some
-existing makefiles, but it brings the behavior of the compiler in
-line with other similar tools. The location of the output files
-can be overridden with the -p command line switch.

-----------------------------------------
-11 November 2002. Summary of changes for version 20021111.
-
-
-0) ACPI Specification 2.0B is released and is now available at:
-http://www.acpi.info/index.html
-
-
-1) ACPI CA Core Subsystem:
-
-Implemented support for the ACPI 2.0 SMBus Operation Regions.
-This includes the early detection and handoff of the request to
-the SMBus region handler (avoiding all of the complex field
-support code), and support for the bidirectional return packet
-from an SMBus write operation. This paves the way for the
-development of SMBus drivers in each host operating system.
-
-Fixed a problem where the semaphore WAIT_FOREVER constant was
-defined as 32 bits, but must be 16 bits according to the ACPI
-specification. This had the side effect of causing ASL
-Mutex/Event timeouts even though the ASL code requested a wait
-forever. Changed all internal references to the ACPI timeout
-parameter to 16 bits to prevent future problems. Changed the name
-of WAIT_FOREVER to ACPI_WAIT_FOREVER.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a much larger code and data size. Note that these values will
-vary depending on the efficiency of the compiler and the compiler
-options used during generation.

-keywords (SMBQuick, SMBWord, etc.)
-
-----------------------------------------
-01 November 2002. Summary of changes for version 20021101.
-
-
-1) ACPI CA Core Subsystem:
-
-Fixed a problem where platforms that have a GPE1 block but no GPE0
-block were not handled correctly. This resulted in a "GPE
-overlap" error message. GPE0 is no longer required.
-
-Removed code added in the previous release that inserted nodes
-into the namespace in alphabetical order. This caused some side-
-effects on various machines. The root cause of the problem is
-still under investigation since in theory, the internal ordering
-of the namespace nodes should not matter.
-
-
-Enhanced error reporting for the case where a named object is not
-found during control method execution. The full ACPI namepath
-(name reference) of the object that was not found is displayed in
-this case.
-
-Note: as a result of the overhaul of the namespace object types in
-the previous release, the namespace nodes for the predefined
-scopes (_TZ, _PR, etc.) are now of the type ACPI_TYPE_LOCAL_SCOPE
-instead of ACPI_TYPE_ANY. This simplifies the namespace
-management code but may affect code that walks the namespace tree
-looking for specific object types.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a much larger code and data size. Note that these values will
-vary depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-
-2) Linux
-
-Fixed a problem introduced in the previous release where the
-Processor and Thermal objects were not recognized and installed in
-/proc. This was related to the scope type change described above.
-
-
-3) iASL Compiler/Disassembler
-
-Implemented the -g option to get all of the required ACPI tables
-from the registry and save them to files (Windows version of the
-compiler only.) The required tables are the FADT, FACS, and DSDT.
-
-Added ACPI table checksum validation during table disassembly in
-order to catch corrupted tables.
-
-
-----------------------------------------
-22 October 2002. Summary of changes for version 20021022.
-
-1) ACPI CA Core Subsystem:
-
-Implemented a restriction on the Scope operator that the target
-must already exist in the namespace at the time the operator is
-encountered (during table load or method execution). In other
-words, forward references are not allowed and Scope() cannot
-create a new object. This changes the previous behavior where the
-interpreter would create the name if not found. This new behavior
-correctly enables the search-to-root algorithm during namespace
-lookup of the target name. Because of this upsearch, this fixes
-the known Compaq _SB_.OKEC problem and makes both the AML
-interpreter and iASL compiler compatible with other ACPI
-implementations.
-
-Completed a major overhaul of the internal ACPI object types for
-the ACPI Namespace and the associated operand objects. Many of
-these types had become obsolete with the introduction of the two-
-pass namespace load. This cleanup simplifies the code and makes
-the entire namespace load mechanism much clearer and easier to
-understand.
-
-Improved debug output for tracking scope opening/closing to help
-diagnose scoping issues. The old scope name as well as the new
-scope name are displayed. Also improved error messages for
-problems with ASL Mutex objects and error messages for GPE
-problems.
-
-Cleaned up the namespace dump code, removed obsolete code.
-
-All string output (for all namespace/object dumps) now uses the
-common ACPI string output procedure which handles escapes properly
-and does not emit non-printable characters.
-
-Fixed some issues with constants in the 64-bit version of the
-local C library (utclib.c)
-
-
-2) Linux
-
-EC Driver: No longer attempts to acquire the Global Lock at
-interrupt level.
-
-
-3) iASL Compiler/Disassembler
-
-Implemented ACPI 2.0B grammar change that disallows all Type 1 and
-2 opcodes outside of a control method. This means that the
-"executable" operators (versus the "namespace" operators) cannot
-be used at the table level; they can only be used within a control
-method.
-
-Implemented the restriction on the Scope() operator where the
-target must already exist in the namespace at the time the
-operator is encountered (during ASL compilation). In other words,
-forward references are not allowed and Scope() cannot create a new
-object. This makes the iASL compiler compatible with other ACPI
-implementations and makes the Scope() implementation adhere to the
-ACPI specification.
-
-Fixed a problem where namepath optimization for the Alias operator
-was optimizing the wrong path (of the two namepaths.) This caused
-a "Missing alias link" error message.
-
-Fixed a problem where an "unknown reserved name" warning could be
-incorrectly generated for names like "_SB" when the trailing
-underscore is not used in the original ASL.
-
-Fixed a problem where the reserved name check did not handle
-NamePaths with multiple NameSegs correctly. The first nameseg of
-the NamePath was examined instead of the last NameSeg.
-
-
-----------------------------------------
-
-02 October 2002. Summary of changes for this release.
-
-
-1) ACPI CA Core Subsystem version 20021002:
-
-Fixed a problem where a store/copy of a string to an existing
-string did not always set the string length properly in the String
-object.
-
-Fixed a reported problem with the ToString operator where the
-behavior was identical to the ToHexString operator instead of just
-simply converting a raw buffer to a string data type.
-
-Fixed a problem where CopyObject and the other "explicit"
-conversion operators were not updating the internal namespace node
-type as part of the store operation.
-
-Fixed a memory leak during implicit source operand conversion
-where the original object was not deleted if it was converted to a
-new object of a different type.
-
-Enhanced error messages for all problems associated with namespace
-lookups. Common procedure generates and prints the lookup name as
-well as the formatted status.
-
-Completed implementation of a new design for the Alias support
-within the namespace. The existing design did not handle the case
-where a new object was assigned to one of the two names due to the
-use of an explicit conversion operator, resulting in the two names
-pointing to two different objects. The new design simply points
-the Alias name to the original name node - not to the object.
-This results in a level of indirection that must be handled in the
-name resolution mechanism.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-
-----------------------------------------
-18 September 2002. Summary of changes for this release.
-
-
-1) ACPI CA Core Subsystem version 20020918:
-
-Fixed a reported problem with reference chaining (via the Index()
-and RefOf() operators) in the ObjectType() and SizeOf() operators.
-The definition of these operators includes the dereferencing of
-all chained references to return information on the base object.
-
-Fixed a problem with stores to indexed package elements - the
-existing code would not complete the store if an "implicit
-conversion" was not performed. In other words, if the existing
-object (package element) was to be replaced completely, the code
-didn't handle this case.
-
-Relaxed typechecking on the ASL "Scope" operator to allow the
-target name to refer to an object of type Integer, String, or
-Buffer, in addition to the scoping object types (Device,
-predefined Scopes, Processor, PowerResource, and ThermalZone.)
-This allows existing AML code that has workarounds for a bug in
-Windows to function properly. A warning is issued, however. This
-affects both the AML interpreter and the iASL compiler. Below is
-an example of this type of ASL code:
-
- Name(DEB,0x00)
- Scope(DEB)
- {
-
-Fixed some reported problems with 64-bit integer support in the
-local implementation of C library functions (clib.c)
-
-
-2) Linux
-
-Use ACPI fix map region instead of IOAPIC region, since it is
-undefined in non-SMP.
-
-Ensure that the SCI has the proper polarity and trigger, even on
-systems that do not have an interrupt override entry in the MADT.
-
-2.5 big driver reorganization (Pat Mochel)
-
-Use early table mapping code from acpitable.c (Andi Kleen)
-
-New blacklist entries (Andi Kleen)
-
-Blacklist improvements. Split blacklist code out into a separate
-file. Move checking the blacklist to very early. Previously, we
-would use ACPI tables, and then halfway through init, check the
-blacklist -- too late. Now, it's early enough to completely fall-
-back to non-ACPI.
-
-
-3) iASL Compiler/Disassembler version 20020918:
-
-Fixed a problem where the typechecking code didn't know that an
-alias could point to a method. In other words, aliases were not
-being dereferenced during typechecking.
-
-
-----------------------------------------
-29 August 2002. Summary of changes for this release.
-
-1) ACPI CA Core Subsystem Version 20020829:
-
-If the target of a Scope() operator already exists, it must be an
-object type that actually opens a scope -- such as a Device,
-Method, Scope, etc. This is a fatal runtime error. Similar error
-check has been added to the iASL compiler also.
-
-Tightened up the namespace load to disallow multiple names in the
-same scope. This previously was allowed if both objects were of
-the same type. (i.e., a lookup was the same as entering a new
-name).
-
-
-2) Linux
-
-Ensure that the ACPI interrupt has the proper trigger and
-polarity.
-
-local_irq_disable is extraneous. (Matthew Wilcox)
-
-Make "acpi=off" actually do what it says, and not use the ACPI
-interpreter *or* the tables.
-
-Added arch-neutral support for parsing SLIT and SRAT tables (Kochi
-Takayoshi)
-
-
-3) iASL Compiler/Disassembler Version 20020829:
-
-Implemented namepath optimization for name declarations. For
-example, a declaration like "Method (\_SB_.ABCD)" would get
-optimized to "Method (ABCD)" if the declaration is within the
-\_SB_ scope. This optimization is in addition to the named
-reference path optimization first released in the previous
-version. This would seem to complete all possible optimizations
-for namepaths within the ASL/AML.
-
-If the target of a Scope() operator already exists, it must be an
-object type that actually opens a scope -- such as a Device,
-Method, Scope, etc.
-
-Implemented a check and warning for unreachable code in the same
-block below a Return() statement.
-
-Fixed a problem where the listing file was not generated if the
-compiler aborted if the maximum error count was exceeded (200).
-
-Fixed a problem where the typechecking of method return values was
-broken. This includes the check for a return value when the
-method is invoked as a TermArg (a return value is expected.)
-
-Fixed a reported problem where EOF conditions during a quoted
-string or comment caused a fault.
-
-
-----------------------------------------
-15 August 2002. Summary of changes for this release.
-
-1) ACPI CA Core Subsystem Version 20020815:
-
-Fixed a reported problem where a Store to a method argument that
-contains a reference did not perform the indirect store correctly.
-This problem was created during the conversion to the new
-reference object model - the indirect store to a method argument
-code was not updated to reflect the new model.
-
-Reworked the ACPI mode change code to better conform to ACPI 2.0,
-handle corner cases, and improve code legibility (Kochi Takayoshi)
-
-Fixed a problem with the pathname parsing for the carat (^)
-prefix. The heavy use of the carat operator by the new namepath
-optimization in the iASL compiler uncovered a problem with the AML
-interpreter handling of this prefix. In the case where one or
-more carats precede a single nameseg, the nameseg was treated as
-standalone and the search rule (to root) was inadvertently
-applied. This could cause both the iASL compiler and the
-interpreter to find the wrong object or to miss the error that
-should occur if the object does not exist at that exact pathname.
-
-Found and fixed the problem where the HP Pavilion DSDT would not
-load. This was a relatively minor tweak to the table loading code
-(a problem caused by the unexpected encounter with a method
-invocation not within a control method), but it does not solve the
-overall issue of the execution of AML code at the table level.
-This investigation is still ongoing.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-2) Linux
-
-Remove redundant slab.h include (Brad Hards)
-
-Fix several bugs in thermal.c (Herbert Nachtnebel)
-
-Make CONFIG_ACPI_BOOT work properly (Pavel Machek)
-
-Change acpi_system_suspend to use updated irq functions (Pavel
-Machek)
-
-Export acpi_get_firmware_table (Matthew Wilcox)
-
-Use proper root proc entry for ACPI (Kochi Takayoshi)
-
-Fix early-boot table parsing (Bjorn Helgaas)
-
-
-3) iASL Compiler/Disassembler
-
-Reworked the compiler options to make them more consistent and to
-use two-letter options where appropriate. We were running out of
-sensible letters. This may break some makefiles, so check the
-current options list by invoking the compiler with no parameters.
-
-Completed the design and implementation of the ASL namepath
-optimization option for the compiler. This option optimizes all
-references to named objects to the shortest possible path. The
-first attempt tries to utilize a single nameseg (4 characters) and
-the "search-to-root" algorithm used by the interpreter. If that
-cannot be used (because either the name is not in the search path
-or there is a conflict with another object with the same name),
-the pathname is optimized using the carat prefix (usually a
-shorter string than specifying the entire path from the root.)
-
-Implemented support to obtain the DSDT from the Windows registry
-(when the disassembly option is specified with no input file).
-Added this code as the implementation for AcpiOsTableOverride in
-the Windows OSL. Migrated the 16-bit code (used in the AcpiDump
-utility) to scan memory for the DSDT to the AcpiOsTableOverride
-function in the DOS OSL to make the disassembler truly OS
-independent.
-
-Implemented a new option to disassemble and compile in one step.
-When used without an input filename, this option will grab the
-DSDT from the local machine, disassemble it, and compile it in one
-step.
-
-Added a warning message for invalid escapes (a backslash followed
-by any character other than the allowable escapes). This catches
-the quoted string error "\_SB_" (which should be "\\_SB_" ).
-
-Also, there are numerous instances in the ACPI specification where
-this error occurs.
-
-Added a compiler option to disable all optimizations. This is
-basically the "compatibility mode" because by using this option,
-the AML code will come out exactly the same as other ASL
-compilers.
-
-Added error messages for incorrectly ordered dependent resource
-functions. This includes: missing EndDependentFn macro at end of
-dependent resource list, nested dependent function macros (both
-start and end), and missing StartDependentFn macro. These are
-common errors that should be caught at compile time.
-
-Implemented _OSI support for the disassembler and compiler. _OSI
-must be included in the namespace for proper disassembly (because
-the disassembler must know the number of arguments.)
-
-Added an "optimization" message type that is optional (off by
-default). This message is used for all optimizations - including
-constant folding, integer optimization, and namepath optimization.
-
-----------------------------------------
-25 July 2002. Summary of changes for this release.
-
-
-1) ACPI CA Core Subsystem Version 20020725:
-
-The AML Disassembler has been enhanced to produce compilable ASL
-code and has been integrated into the iASL compiler (see below) as
-well as the single-step disassembly for the AML debugger and the
-disassembler for the AcpiDump utility. All ACPI 2.0A opcodes,
-resource templates and macros are fully supported. The
-disassembler has been tested on over 30 different AML files,
-producing identical AML when the resulting disassembled ASL file
-is recompiled with the same ASL compiler.
-
-Modified the Resource Manager to allow zero interrupts and zero
-dma channels during the GetCurrentResources call. This was
-causing problems on some platforms.
-
-Added the AcpiOsRedirectOutput interface to the OSL to simplify
-output redirection for the AcpiOsPrintf and AcpiOsVprintf
-interfaces.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

- Non-Debug Version: 69.1K Code, 8.2K Data, 77.3K Total
- Debug Version: 149.4K Code, 61.6K Data, 211.0K Total
-
-
-2) Linux
-
-Fixed a panic in the EC driver (Dominik Brodowski)
-
-Implemented checksum of the R/XSDT itself during Linux table scan
-(Richard Schaal)
-
-
-3) iASL compiler
-
-The AML disassembler is integrated into the compiler. The "-d"
-option invokes the disassembler to completely disassemble an
-input AML file, producing as output a text ASL file with the
-extension ".dsl" (to avoid name collisions with existing .asl
-source files.) A future enhancement will allow the disassembler
-to obtain the BIOS DSDT from the registry under Windows.
-
-Fixed a problem with the VendorShort and VendorLong resource
-descriptors where an invalid AML sequence was created.
-
-Implemented a fix for BufferData term in the ASL parser. It was
-inadvertently defined twice, allowing invalid syntax to pass and
-causing reduction conflicts.
-
-Fixed a problem where the Ones opcode could get converted to a
-value of zero if "Ones" was used where a byte, word or dword value
-was expected. The 64-bit value is now truncated to the correct
-size with the correct value.
-
-
-
-----------------------------------------
-02 July 2002. Summary of changes for this release.
-
-
-1) ACPI CA Core Subsystem Version 20020702:
-
-The Table Manager code has been restructured to add several new
-features. Tables that are not required by the core subsystem
-(other than the FADT, DSDT, FACS, PSDTs, etc.) are no longer
-validated in any way and are returned from AcpiGetFirmwareTable if
-requested. The AcpiOsTableOverride interface is now called for
-each table that is loaded by the subsystem in order to allow the
-host to override any table it chooses. Previously, only the DSDT
-could be overridden. Added one new files, tbrsdt.c and
-tbgetall.c.
-
-Fixed a problem with the conversion of internal package objects to
-external objects (when a package is returned from a control
-method.) The return buffer length was set to zero instead of the
-proper length of the package object.
-
-Fixed a reported problem with the use of the RefOf and DeRefOf
-operators when passing reference arguments to control methods. A
-new type of Reference object is used internally for references
-produced by the RefOf operator.
-
-Added additional error messages in the Resource Manager to explain
-AE_BAD_DATA errors when they occur during resource parsing.
-
-Split the AcpiEnableSubsystem into two primitives to enable a
-finer granularity initialization sequence. These two calls should
-be called in this order: AcpiEnableSubsystem (flags),
-AcpiInitializeObjects (flags). The flags parameter remains the
-same.
-
-
-2) Linux
-
-Updated the ACPI utilities module to understand the new style of
-fully resolved package objects that are now returned from the core
-subsystem. This eliminates errors of the form:
-
- ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PPB_._PRT]
- acpi_utils-0430 [145] acpi_evaluate_reference:
- Invalid element in package (not a device reference)
-
-The method evaluation utility uses the new buffer allocation
-scheme instead of calling AcpiEvaluate Object twice.
-
-Added support for ECDT. This allows the use of the Embedded
-
-Controller before the namespace has been fully initialized, which
-is necessary for ACPI 2.0 support, and for some laptops to
-initialize properly. (Laptops using ECDT are still rare, so only
-limited testing was performed of the added functionality.)
-
-Fixed memory leaks in the EC driver.
-
-Eliminated a brittle code structure in acpi_bus_init().
-
-Eliminated the acpi_evaluate() helper function in utils.c. It is
-no longer needed since acpi_evaluate_object can optionally
-allocate memory for the return object.
-
-Implemented fix for keyboard hang when getting battery readings on
-some systems (Stephen White)
-
-PCI IRQ routing update (Dominik Brodowski)
-
-Fix an ifdef to allow compilation on UP with LAPIC but no IOAPIC
-support
-
-----------------------------------------
-11 June 2002. Summary of changes for this release.
-
-
-1) ACPI CA Core Subsystem Version 20020611:
-
-Fixed a reported problem where constants such as Zero and One
-appearing within _PRT packages were not handled correctly within
-the resource manager code. Originally reported against the ASL
-compiler because the code generator now optimizes integers to
-their minimal AML representation (i.e. AML constants if possible.)
-The _PRT code now handles all AML constant opcodes correctly
-(Zero, One, Ones, Revision).
-
-Fixed a problem with the Concatenate operator in the AML
-interpreter where a buffer result object was incorrectly marked as
-not fully evaluated, causing a run-time error of AE_AML_INTERNAL.
-
-All package sub-objects are now fully resolved before they are
-returned from the external ACPI interfaces. This means that name
-strings are resolved to object handles, and constant operators
-(Zero, One, Ones, Revision) are resolved to Integers.
-
-Implemented immediate resolution of the AML Constant opcodes
-(Zero, One, Ones, Revision) to Integer objects upon detection
-within the AML stream. This has simplified and reduced the
-generated code size of the subsystem by eliminating about 10
-switch statements for these constants (which previously were
-contained in Reference objects.) The complicating issues are that
-the Zero opcode is used as a "placeholder" for unspecified
-optional target operands and stores to constants are defined to be
-no-ops.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-
-2) Linux
-
-
-Added preliminary support for obtaining _TRA data for PCI root
-bridges (Bjorn Helgaas).
-
-
-3) iASL Compiler Version X2046:
-
-Fixed a problem where the "_DDN" reserved name was defined to be a
-control method with one argument. There are no arguments, and
-_DDN does not have to be a control method.
-
-Fixed a problem with the Linux version of the compiler where the
-source lines printed with error messages were the wrong lines.
-This turned out to be the "LF versus CR/LF" difference between
-Windows and Unix. This appears to be the longstanding issue
-concerning listing output and error messages.
-
-Fixed a problem with the Linux version of compiler where opcode
-names within error messages were wrong. This was caused by a
-slight difference in the output of the Flex tool on Linux versus
-Windows.
-
-Fixed a problem with the Linux compiler where the hex output files
-contained some garbage data caused by an internal buffer overrun.
-
-
-----------------------------------------
-17 May 2002. Summary of changes for this release.
-
-
-1) ACPI CA Core Subsystem Version 20020517:
-
-Implemented a workaround to an BIOS bug discovered on the HP
-OmniBook where the FADT revision number and the table size are
-inconsistent (ACPI 2.0 revision vs. ACPI 1.0 table size). The new
-behavior is to fallback to using only the ACPI 1.0 fields of the
-FADT if the table is too small to be a ACPI 2.0 table as claimed
-by the revision number. Although this is a BIOS bug, this is a
-case where the workaround is simple enough and with no side
-effects, so it seemed prudent to add it. A warning message is
-issued, however.
-
-Implemented minimum size checks for the fixed-length ACPI tables -
-- the FADT and FACS, as well as consistency checks between the
-revision number and the table size.
-
-Fixed a reported problem in the table override support where the
-new table pointer was incorrectly treated as a physical address
-instead of a logical address.
-
-Eliminated the use of the AE_AML_ERROR exception and replaced it
-with more descriptive codes.
-
-Fixed a problem where an exception would occur if an ASL Field was
-defined with no named Field Units underneath it (used by some
-index fields).
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-2) Linux
-
-Much work done on ACPI init (MADT and PCI IRQ routing support).
-(Paul D. and Dominik Brodowski)
-
-Fix PCI IRQ-related panic on boot (Sam Revitch)
-
-Set BM_ARB_DIS when entering a sleep state (Ducrot Bruno)
-
-Fix "MHz" typo (Dominik Brodowski)
-
-Fix RTC year 2000 issue (Dominik Brodowski)
-
-Preclude multiple button proc entries (Eric Brunet)
-
-Moved arch-specific code out of include/platform/aclinux.h
-
-3) iASL Compiler Version X2044:
-
-Implemented error checking for the string used in the EISAID macro
-(Usually used in the definition of the _HID object.) The code now
-strictly enforces the PnP format - exactly 7 characters, 3
-uppercase letters and 4 hex digits.
-
-If a raw string is used in the definition of the _HID object
-(instead of the EISAID macro), the string must contain all
-alphanumeric characters (e.g., "*PNP0011" is not allowed because
-of the asterisk.)
-
-Implemented checking for invalid use of ACPI reserved names for
-most of the name creation operators (Name, Device, Event, Mutex,
-OperationRegion, PowerResource, Processor, and ThermalZone.)
-Previously, this check was only performed for control methods.
-
-Implemented an additional check on the Name operator to emit an
-error if a reserved name that must be implemented in ASL as a
-control method is used. We know that a reserved name must be a
-method if it is defined with input arguments.
-
-The warning emitted when a namespace object reference is not found
-during the cross reference phase has been changed into an error.
-The "External" directive should be used for names defined in other
-modules.
-
-
-4) Tools and Utilities
-
-The 16-bit tools (adump16 and aexec16) have been regenerated and
-tested.
-
-Fixed a problem with the output of both acpidump and adump16 where
-the indentation of closing parentheses and brackets was not
-
-aligned properly with the parent block.
-
-
-----------------------------------------
-03 May 2002. Summary of changes for this release.
-
-
-1) ACPI CA Core Subsystem Version 20020503:
-
-Added support a new OSL interface that allows the host operating
-
-system software to override the DSDT found in the firmware -
-AcpiOsTableOverride. With this interface, the OSL can examine the
-version of the firmware DSDT and replace it with a different one
-if desired.
-
-Added new external interfaces for accessing ACPI registers from
-device drivers and other system software - AcpiGetRegister and
-AcpiSetRegister. This was simply an externalization of the
-existing AcpiHwBitRegister interfaces.
-
-Fixed a regression introduced in the previous build where the
-ASL/AML CreateField operator always returned an error,
-"destination must be a NS Node".
-
-Extended the maximum time (before failure) to successfully enable
-ACPI mode to 3 seconds.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-Enhanced ACPI init code for SMP. We are now fully MPS and $PIR-
-free. While 3 out of 4 of our in-house systems work fine, the last
-one still hangs when testing the LAPIC timer.
-
-Renamed many files in 2.5 kernel release to omit "acpi_" from the

-
-Added warning on boot for Presario 711FR.

-
-3) iASL Compiler Version X2043:
-
-Added support to allow the compiler to be integrated into the MS
-VC++ development environment for one-button compilation of single
-files or entire projects -- with error-to-source-line mapping.
-
-Implemented support for compile-time constant folding for the
-Type3, Type4, and Type5 opcodes first defined in the ACPI 2.0
-specification. This allows the ASL writer to use expressions
-instead of Integer/Buffer/String constants in terms that must
-evaluate to constants at compile time and will also simplify the
-emitted AML in any such sub-expressions that can be folded
-(evaluated at compile-time.) This increases the size of the
-compiler significantly because a portion of the ACPI CA AML
-interpreter is included within the compiler in order to pre-
-evaluate constant expressions.
-
-
-Fixed a problem with the "Unicode" ASL macro that caused the
-compiler to fault. (This macro is used in conjunction with the
-_STR reserved name.)
-
-Implemented an AML opcode optimization to use the Zero, One, and
-Ones opcodes where possible to further reduce the size of integer
-constants and thus reduce the overall size of the generated AML
-code.
-
-Implemented error checking for new reserved terms for ACPI version
-2.0A.
-
-Implemented the -qr option to display the current list of ACPI
-reserved names known to the compiler.
-
-Implemented the -qc option to display the current list of ASL
-operators that are allowed within constant expressions and can
-therefore be folded at compile time if the operands are constants.
-
-
-4) Documentation
-
-Updated the Programmer's Reference for new interfaces, data types,
-and memory allocation model options.
-
-Updated the iASL Compiler User Reference to apply new format and
-add information about new features and options.
-
-----------------------------------------
-19 April 2002. Summary of changes for this release.
-
-1) ACPI CA Core Subsystem Version 20020419:
-
-The source code base for the Core Subsystem has been completely
-cleaned with PC-lint (FlexLint) for both 32-bit and 64-bit
-versions. The Lint option files used are included in the
-/acpi/generate/lint directory.
-
-Implemented enhanced status/error checking across the entire
-Hardware manager subsystem. Any hardware errors (reported from
-the OSL) are now bubbled up and will abort a running control
-method.
-
-
-Fixed a problem where the per-ACPI-table integer width (32 or 64)
-was stored only with control method nodes, causing a fault when
-non-control method code was executed during table loading. The
-solution implemented uses a global variable to indicate table
-width across the entire ACPI subsystem. Therefore, ACPI CA does
-not support mixed integer widths across different ACPI tables
-(DSDT, SSDT).
-
-Fixed a problem where NULL extended fields (X fields) in an ACPI
-2.0 ACPI FADT caused the table load to fail. Although the
-existing ACPI specification is a bit fuzzy on this topic, the new
-behavior is to fall back on a ACPI 1.0 field if the corresponding
-ACPI 2.0 X field is zero (even though the table revision indicates
-a full ACPI 2.0 table.) The ACPI specification will be updated to
-clarify this issue.
-
-Fixed a problem with the SystemMemory operation region handler
-where memory was always accessed byte-wise even if the AML-
-specified access width was larger than a byte. This caused
-problems on systems with memory-mapped I/O. Memory is now
-accessed with the width specified. On systems that do not support
-non-aligned transfers, a check is made to guarantee proper address
-alignment before proceeding in order to avoid an AML-caused
-alignment fault within the kernel.
-
-
-Fixed a problem with the ExtendedIrq resource where only one byte
-of the 4-byte Irq field was extracted.
-
-Fixed the AcpiExDigitsNeeded() procedure to support _UID. This
-function was out of date and required a rewrite.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-2) Linux
-
-PCI IRQ routing fixes (Dominik Brodowski)
-
-
-3) iASL Compiler Version X2042:
-
-Implemented an additional compile-time error check for a field
-unit whose size + minimum access width would cause a run-time
-access beyond the end-of-region. Previously, only the field size
-itself was checked.
-
-The Core subsystem and iASL compiler now share a common parse
-object in preparation for compile-time evaluation of the type
-3/4/5 ASL operators.
-
-
-----------------------------------------
-Summary of changes for this release: 03_29_02
-
-1) ACPI CA Core Subsystem Version 20020329:
-
-Implemented support for late evaluation of TermArg operands to
-Buffer and Package objects. This allows complex expressions to be
-used in the declarations of these object types.
-
-Fixed an ACPI 1.0 compatibility issue when reading Fields. In ACPI
-1.0, if the field was larger than 32 bits, it was returned as a
-buffer - otherwise it was returned as an integer. In ACPI 2.0,
-the field is returned as a buffer only if the field is larger than
-64 bits. The TableRevision is now considered when making this
-conversion to avoid incompatibility with existing ASL code.
-
-Implemented logical addressing for AcpiOsGetRootPointer. This
-allows an RSDP with either a logical or physical address. With
-this support, the host OS can now override all ACPI tables with
-one logical RSDP. Includes implementation of "typed" pointer
-support to allow a common data type for both physical and logical
-pointers internally. This required a change to the
-AcpiOsGetRootPointer interface.
-
-Implemented the use of ACPI 2.0 Generic Address Structures for all
-GPE, Fixed Event, and PM Timer I/O. This allows the use of memory
-mapped I/O for these ACPI features.
-
-Initialization now ignores not only non-required tables (All
-tables other than the FADT, FACS, DSDT, and SSDTs), but also does
-not validate the table headers of unrecognized tables.
-
-Fixed a problem where a notify handler could only be
-installed/removed on an object of type Device. All "notify"
-
-objects are now supported -- Devices, Processor, Power, and
-Thermal.
-
-Removed most verbosity from the ACPI_DB_INFO debug level. Only
-critical information is returned when this debug level is enabled.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

- Debug Version: 139.8K Code, 57.4K Data, 197.2K Total
-
-
-2) Linux:
-
-The processor driver (acpi_processor.c) now fully supports ACPI
-2.0-based processor performance control (e.g. Intel(R)
-SpeedStep(TM) technology) Note that older laptops that only have
-the Intel "applet" interface are not supported through this. The
-'limit' and 'performance' interface (/proc) are fully functional.
-[Note that basic policy for controlling performance state
-transitions will be included in the next version of ospmd.] The
-idle handler was modified to more aggressively use C2, and PIIX4
-errata handling underwent a complete overhaul (big thanks to
-Dominik Brodowski).
-
-Added support for ACPI-PCI device binding (acpi_pci_root.c). _ADR-
-based devices in the ACPI namespace are now dynamically bound
-(associated) with their PCI counterparts (e.g. PCI1->01:00.0).
-This allows, among other things, ACPI to resolve bus numbers for
-subordinate PCI bridges.
-
-Enhanced PCI IRQ routing to get the proper bus number for _PRT
-entries defined underneath PCI bridges.
-
-Added IBM 600E to bad bios list due to invalid _ADR value for
-PIIX4 PCI-ISA bridge, resulting in improper PCI IRQ routing.
-
-In the process of adding full MADT support (e.g. IOAPIC) for IA32
-(acpi.c, mpparse.c) -- stay tuned.
-
-Added back visual differentiation between fixed-feature and
-control-method buttons in dmesg. Buttons are also subtyped (e.g.
-button/power/PWRF) to simplify button identification.
-
-We no longer use -Wno-unused when compiling debug. Please ignore
-any "_THIS_MODULE defined but not used" messages.
-
-Can now shut down the system using "magic sysrq" key.
-
-
-3) iASL Compiler version 2041:
-
-Fixed a problem where conversion errors for hex/octal/decimal
-constants were not reported.
-
-Implemented a fix for the General Register template Address field.
-This field was 8 bits when it should be 64.
-
-Fixed a problem where errors/warnings were no longer being emitted
-within the listing output file.
-
-Implemented the ACPI 2.0A restriction on ACPI Table Signatures to
-exactly 4 characters, alphanumeric only.
-
-
-
-
-----------------------------------------
-Summary of changes for this release: 03_08_02
-
-
-1) ACPI CA Core Subsystem Version 20020308:
-
-Fixed a problem with AML Fields where the use of the "AccessAny"
-keyword could cause an interpreter error due to attempting to read
-or write beyond the end of the parent Operation Region.
-
-Fixed a problem in the SystemMemory Operation Region handler where
-an attempt was made to map memory beyond the end of the region.
-This was the root cause of the "AE_ERROR" and "AE_NO_MEMORY"
-errors on some Linux systems.
-
-Fixed a problem where the interpreter/namespace "search to root"
-algorithm was not functioning for some object types. Relaxed the
-internal restriction on the search to allow upsearches for all
-external object types as well as most internal types.
-
-
-2) Linux:
-
-We now use safe_halt() macro versus individual calls to sti | hlt.
-
-Writing to the processor limit interface should now work. "echo 1"
-will increase the limit, 2 will decrease, and 0 will reset to the
-
-default.
-
-
-3) ASL compiler:
-
-Fixed segfault on Linux version.
-
-
-----------------------------------------
-Summary of changes for this release: 02_25_02
-
-1) ACPI CA Core Subsystem:
-
-
-Fixed a problem where the GPE bit masks were not initialized
-properly, causing erratic GPE behavior.
-
-Implemented limited support for multiple calling conventions. The
-code can be generated with either the VPL (variable parameter
-list, or "C") convention, or the FPL (fixed parameter list, or
-"Pascal") convention. The core subsystem is about 3.4% smaller
-when generated with FPL.
-
-
-2) Linux
-
-Re-add some /proc/acpi/event functionality that was lost during
-the rewrite
-
-Resolved issue with /proc events for fixed-feature buttons showing
-up as the system device.
-
-Fixed checks on C2/C3 latencies to be inclusive of maximum values.
-
-Replaced AE_ERRORs in acpi_osl.c with more specific error codes.
-
-Changed ACPI PRT option from "pci=noacpi-routing" to "pci=noacpi"
-
-Fixed limit interface & usage to fix bugs with passive cooling
-hysterisis.
-
-Restructured PRT support.
-
-
-----------------------------------------
-Summary of changes for this label: 02_14_02
-
-
-1) ACPI CA Core Subsystem:
-
-Implemented support in AcpiLoadTable to allow loading of FACS and
-FADT tables.
-
-Suport for the now-obsolete interim 0.71 64-bit ACPI tables has
-been removed. All 64-bit platforms should be migrated to the ACPI
-2.0 tables. The actbl71.h header has been removed from the source
-tree.
-
-All C macros defined within the subsystem have been prefixed with
-"ACPI_" to avoid collision with other system include files.
-
-Removed the return value for the two AcpiOsPrint interfaces, since
-it is never used and causes lint warnings for ignoring the return
-value.
-
-Added error checking to all internal mutex acquire and release
-calls. Although a failure from one of these interfaces is
-probably a fatal system error, these checks will cause the
-immediate abort of the currently executing method or interface.
-
-Fixed a problem where the AcpiSetCurrentResources interface could
-fault. This was a side effect of the deployment of the new memory
-allocation model.
-
-Fixed a couple of problems with the Global Lock support introduced
-in the last major build. The "common" (1.0/2.0) internal FACS was
-being overwritten with the FACS signature and clobbering the
-Global Lock pointer. Also, the actual firmware FACS was being
-unmapped after construction of the "common" FACS, preventing
-access to the actual Global Lock field within it. The "common"
-internal FACS is no longer installed as an actual ACPI table; it
-is used simply as a global.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-
-2) Linux
-
-Updated Linux-specific code for core macro and OSL interface
-changes described above.
-
-Improved /proc/acpi/event. It now can be opened only once and has
-proper poll functionality.
-
-Fixed and restructured power management (acpi_bus).
-
-Only create /proc "view by type" when devices of that class exist.
-
-Fixed "charging/discharging" bug (and others) in acpi_battery.
-
-Improved thermal zone code.
-
-
-3) ASL Compiler, version X2039:
-
-
-Implemented the new compiler restriction on ASL String hex/octal
-escapes to non-null, ASCII values. An error results if an invalid
-value is used. (This will require an ACPI 2.0 specification
-change.)
-
-AML object labels that are output to the optional C and ASM source
-are now prefixed with both the ACPI table signature and table ID
-to help guarantee uniqueness within a large BIOS project.
-
-
-----------------------------------------
-Summary of changes for this label: 02_01_02
-
-1) ACPI CA Core Subsystem:
-
-ACPI 2.0 support is complete in the entire Core Subsystem and the
-ASL compiler. All new ACPI 2.0 operators are implemented and all
-other changes for ACPI 2.0 support are complete. With
-simultaneous code and data optimizations throughout the subsystem,
-ACPI 2.0 support has been implemented with almost no additional
-cost in terms of code and data size.
-
-Implemented a new mechanism for allocation of return buffers. If
-the buffer length is set to ACPI_ALLOCATE_BUFFER, the buffer will
-be allocated on behalf of the caller. Consolidated all return
-buffer validation and allocation to a common procedure. Return
-buffers will be allocated via the primary OSL allocation interface
-since it appears that a separate pool is not needed by most users.
-If a separate pool is required for these buffers, the caller can
-still use the original mechanism and pre-allocate the buffer(s).
-
-Implemented support for string operands within the DerefOf
-operator.
-
-Restructured the Hardware and Event managers to be table driven,
-simplifying the source code and reducing the amount of generated
-code.
-
-Split the common read/write low-level ACPI register bitfield
-procedure into a separate read and write, simplifying the code
-considerably.
-
-Obsoleted the AcpiOsCallocate OSL interface. This interface was
-used only a handful of times and didn't have enough critical mass
-for a separate interface. Replaced with a common calloc procedure
-in the core.
-
-Fixed a reported problem with the GPE number mapping mechanism
-that allows GPE1 numbers to be non-contiguous with GPE0.
-Reorganized the GPE information and shrunk a large array that was
-originally large enough to hold info for all possible GPEs (256)
-to simply large enough to hold all GPEs up to the largest GPE
-number on the machine.
-
-Fixed a reported problem with resource structure alignment on 64-
-bit platforms.
-
-Changed the AcpiEnableEvent and AcpiDisableEvent external
-interfaces to not require any flags for the common case of
-enabling/disabling a GPE.
-
-Implemented support to allow a "Notify" on a Processor object.
-
-Most TBDs in comments within the source code have been resolved
-and eliminated.
-
-
-Fixed a problem in the interpreter where a standalone parent
-prefix (^) was not handled correctly in the interpreter and
-debugger.
-
-Removed obsolete and unnecessary GPE save/restore code.
-
-Implemented Field support in the ASL Load operator. This allows a
-table to be loaded from a named field, in addition to loading a
-table directly from an Operation Region.
-
-Implemented timeout and handle support in the external Global Lock
-interfaces.
-
-Fixed a problem in the AcpiDump utility where pathnames were no
-longer being generated correctly during the dump of named objects.
-
-Modified the AML debugger to give a full display of if/while
-predicates instead of just one AML opcode at a time. (The
-predicate can have several nested ASL statements.) The old method
-was confusing during single stepping.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-2) Linux
-
- Implemented fix for PIIX reverse throttling errata (Processor
-driver)
-
-Added new Limit interface (Processor and Thermal drivers)
-
-New thermal policy (Thermal driver)
-
-Many updates to /proc
-
-Battery "low" event support (Battery driver)
-
-Supports ACPI PCI IRQ routing (PCI Link and PCI root drivers)
-
-IA32 - IA64 initialization unification, no longer experimental
-
-Menuconfig options redesigned
-
-3) ASL Compiler, version X2037:
-
-Implemented several new output features to simplify integration of
-AML code into firmware: 1) Output the AML in C source code with
-labels for each named ASL object. The original ASL source code
-is interleaved as C comments. 2) Output the AML in ASM source code
-with labels and interleaved ASL source. 3) Output the AML in
-raw hex table form, in either C or ASM.
-
-Implemented support for optional string parameters to the
-LoadTable operator.
-
-Completed support for embedded escape sequences within string
-literals. The compiler now supports all single character escapes
-as well as the Octal and Hex escapes. Note: the insertion of a
-null byte into a string literal (via the hex/octal escape) causes
-the string to be immediately terminated. A warning is issued.
-
-Fixed a problem where incorrect AML was generated for the case
-where an ASL namepath consists of a single parent prefix (
-
-) with no trailing name segments.
-
-The compiler has been successfully generated with a 64-bit C
-compiler.
-
-
-
-
-----------------------------------------
-Summary of changes for this label: 12_18_01
-
-1) Linux
-
-Enhanced blacklist with reason and severity fields. Any table's
-signature may now be used to identify a blacklisted system.
-
-Call _PIC control method to inform the firmware which interrupt
-model the OS is using. Turn on any disabled link devices.
-
-Cleaned up busmgr /proc error handling (Andreas Dilger)
-
- 2) ACPI CA Core Subsystem:
-
-Implemented ACPI 2.0 semantics for the "Break" operator (Exit from
-while loop)
-
-Completed implementation of the ACPI 2.0 "Continue",
-"ConcatenateResTemplate", "DataTableRegion", and "LoadTable"
-operators. All new ACPI 2.0 operators are now implemented in both
-the ASL compiler and the AML interpreter. The only remaining ACPI
-2.0 task is support for the String data type in the DerefOf
-operator. Fixed a problem with AcquireMutex where the status code
-was lost if the caller had to actually wait for the mutex.
-
-Increased the maximum ASL Field size from 64K bits to 4G bits.
-
-Completed implementation of the external Global Lock interfaces --
-AcpiAcquireGlobalLock and AcpiReleaseGlobalLock. The Timeout and
-Handler parameters were added.
-
-Completed another pass at removing warnings and issues when
-compiling with 64-bit compilers. The code now compiles cleanly
-with the Intel 64-bit C/C++ compiler. Most notably, the pointer
-add and subtract (diff) macros have changed considerably.
-
-
-Created and deployed a new ACPI_SIZE type that is 64-bits wide on
-64-bit platforms, 32-bits on all others. This type is used
-wherever memory allocation and/or the C sizeof() operator is used,
-and affects the OSL memory allocation interfaces AcpiOsAllocate
-and AcpiOsCallocate.
-
-Implemented sticky user breakpoints in the AML debugger.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-compiler.
-
- ----------------------------------------
-Summary of changes for this label: 12_05_01
-
- 1) ACPI CA Core Subsystem:
-
-The ACPI 2.0 CopyObject operator is fully implemented. This
-operator creates a new copy of an object (and is also used to
-bypass the "implicit conversion" mechanism of the Store operator.)
-
-The ACPI 2.0 semantics for the SizeOf operator are fully
-implemented. The change is that performing a SizeOf on a
-reference object causes an automatic dereference of the object to
-tha actual value before the size is evaluated. This behavior was
-undefined in ACPI 1.0.
-
-The ACPI 2.0 semantics for the Extended IRQ resource descriptor
-have been implemented. The interrupt polarity and mode are now
-independently set.
-
-Fixed a problem where ASL Constants (Zero, One, Ones, Revision)
-appearing in Package objects were not properly converted to
-integers when the internal Package was converted to an external
-object (via the AcpiEvaluateObject interface.)
-
-Fixed a problem with the namespace object deletion mechanism for
-objects created by control methods. There were two parts to this
-problem: 1) Objects created during the initialization phase method
-parse were not being deleted, and 2) The object owner ID mechanism
-to track objects was broken.
-
-Fixed a problem where the use of the ASL Scope operator within a
-control method would result in an invalid opcode exception.
-
-Fixed a problem introduced in the previous label where the buffer
-length required for the _PRT structure was not being returned
-correctly.
-
-Code and Data Size: Current core subsystem library sizes are shown
-below. These are the code and data sizes for the acpica.lib
-produced by the Microsoft Visual C++ 6.0 compiler, and these
-values do not include any ACPI driver or OSPM code. The debug
-version of the code includes the debug output trace mechanism and
-has a larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

- 2) Linux:
-
-Updated all files to apply cleanly against 2.4.16.
-
-Added basic PCI Interrupt Routing Table (PRT) support for IA32
-(acpi_pci.c), and unified the PRT code for IA32 and IA64. This
-version supports both static and dyanmic PRT entries, but dynamic
-entries are treated as if they were static (not yet
-reconfigurable). Architecture- specific code to use this data is
-absent on IA32 but should be available shortly.
-
-Changed the initialization sequence to start the ACPI interpreter
-(acpi_init) prior to initialization of the PCI driver (pci_init)
-in init/main.c. This ordering is required to support PRT and
-facilitate other (future) enhancement. A side effect is that the
-ACPI bus driver and certain device drivers can no longer be loaded
-as modules.
-
-Modified the 'make menuconfig' options to allow PCI Interrupt
-Routing support to be included without the ACPI Bus and other
-device drivers.
-
- 3) ASL Compiler, version X2033:
-
-Fixed some issues with the use of the new CopyObject and
-DataTableRegion operators. Both are fully functional.

-Summary of changes for this label: 11_20_01
-
- 20 November 2001. Summary of changes for this release.
-
- 1) ACPI CA Core Subsystem:
-
-Updated Index support to match ACPI 2.0 semantics. Storing a
-Integer, String, or Buffer to an Index of a Buffer will store only
-the least-significant byte of the source to the Indexed buffer
-byte. Multiple writes are not performed.
-
-Fixed a problem where the access type used in an AccessAs ASL
-operator was not recorded correctly into the field object.
-
-Fixed a problem where ASL Event objects were created in a
-signalled state. Events are now created in an unsignalled state.
-
-The internal object cache is now purged after table loading and
-initialization to reduce the use of dynamic kernel memory -- on
-the assumption that object use is greatest during the parse phase
-of the entire table (versus the run-time use of individual control
-methods.)
-
-ACPI 2.0 variable-length packages are now fully operational.
-
-Code and Data Size: Code and Data optimizations have permitted new
-feature development with an actual reduction in the library size.
-Current core subsystem library sizes are shown below. These are
-the code and data sizes for the acpica.lib produced by the
-Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code
-includes the debug output trace mechanism and has a larger code
-and data size. Note that these values will vary depending on the
-efficiency of the compiler and the compiler options used during
-generation.
-

- Debug Version: 135.1K Code, 55.4K Data, 190.5K Total
-
- 2) Linux:
-
-Enhanced the ACPI boot-time initialization code to allow the use
-of Local APIC tables for processor enumeration on IA-32, and to
-pave the way for a fully MPS-free boot (on SMP systems) in the
-near future. This functionality replaces
-arch/i386/kernel/acpitables.c, which was introduced in an earlier
-2.4.15-preX release. To enable this feature you must add
-"acpi_boot=on" to the kernel command line -- see the help entry
-for CONFIG_ACPI_BOOT for more information. An IA-64 release is in
-the works...
-
-Restructured the configuration options to allow boot-time table
-parsing support without inclusion of the ACPI Interpreter (and
-other) code.
-
-NOTE: This release does not include fixes for the reported events,
-power-down, and thermal passive cooling issues (coming soon).
-
- 3) ASL Compiler:
-
-Added additional typechecking for Fields within restricted access
-Operation Regions. All fields within EC and CMOS regions must be
-declared with ByteAcc. All fields withing SMBus regions must be
-declared with the BufferAcc access type.
-
-Fixed a problem where the listing file output of control methods
-no longer interleaved the actual AML code with the ASL source
-code.
-
-
-
-
-----------------------------------------
-Summary of changes for this label: 11_09_01
-
-1) ACPI CA Core Subsystem:
-
-Implemented ACPI 2.0-defined support for writes to fields with a
-Buffer, String, or Integer source operand that is smaller than the
-target field. In these cases, the source operand is zero-extended
-to fill the target field.
-
-Fixed a problem where a Field starting bit offset (within the
-parent operation region) was calculated incorrectly if the
-
-alignment of the field differed from the access width. This
-affected CreateWordField, CreateDwordField, CreateQwordField, and
-possibly other fields that use the "AccessAny" keyword.
-
-Fixed a problem introduced in the 11_02_01 release where indirect
-stores through method arguments did not operate correctly.
-
-2) Linux:
-
-Implemented boot-time ACPI table parsing support
-(CONFIG_ACPI_BOOT) for IA32 and IA64 UP/SMP systems. This code
-facilitates the use of ACPI tables (e.g. MADT, SRAT) rather than
-legacy BIOS interfaces (e.g. MPS) for the configuration of system
-processors, memory, and interrupts during setup_arch(). Note that
-this patch does not include the required architecture-specific
-changes required to apply this information -- subsequent patches
-will be posted for both IA32 and IA64 to achieve this.
-
-Added low-level sleep support for IA32 platforms, courtesy of Pat
-Mochel. This allows IA32 systems to transition to/from various
-sleeping states (e.g. S1, S3), although the lack of a centralized
-driver model and power-manageable drivers will prevent its
-(successful) use on most systems.
-
-Revamped the ACPI 'menuconfig' layout: created new "ACPI Support"
-submenu, unified IA32 and IA64 options, added new "Boot using ACPI
-tables" option, etc.
-
-Increased the default timeout for the EC driver from 1ms to 10ms
-(1000 cycles of 10us) to try to address AE_TIME errors during EC
-transactions.
-
- ----------------------------------------
-Summary of changes for this label: 11_02_01
-
-1) ACPI CA Core Subsystem:
-
-ACPI 2.0 Support: Implemented ACPI 2.0 64-bit Field access
-(QWordAcc keyword). All ACPI 2.0 64-bit support is now
-implemented.
-
-OSL Interfaces: Several of the OSL (AcpiOs*) interfaces required
-changes to support ACPI 2.0 Qword field access. Read/Write
-PciConfiguration(), Read/Write Memory(), and Read/Write Port() now
-accept an ACPI_INTEGER (64 bits) as the value parameter. Also,
-the value parameter for the address space handler interface is now
-an ACPI_INTEGER. OSL implementations of these interfaces must now
-handle the case where the Width parameter is 64.
-
-Index Fields: Fixed a problem where unaligned bit assembly and
-disassembly for IndexFields was not supported correctly.
-
-Index and Bank Fields: Nested Index and Bank Fields are now
-supported. During field access, a check is performed to ensure
-that the value written to an Index or Bank register is not out of
-the range of the register. The Index (or Bank) register is
-written before each access to the field data. Future support will
-include allowing individual IndexFields to be wider than the
-DataRegister width.
-
-Fields: Fixed a problem where the AML interpreter was incorrectly
-attempting to write beyond the end of a Field/OpRegion. This was
-a boundary case that occurred when a DWORD field was written to a
-BYTE access OpRegion, forcing multiple writes and causing the
-interpreter to write one datum too many.
-
-Fields: Fixed a problem with Field/OpRegion access where the
-starting bit address of a field was incorrectly calculated if the
-current access type was wider than a byte (WordAcc, DwordAcc, or
-QwordAcc).
-
-Fields: Fixed a problem where forward references to individual
-FieldUnits (individual Field names within a Field definition) were
-not resolved during the AML table load.
-
-Fields: Fixed a problem where forward references from a Field
-definition to the parent Operation Region definition were not
-resolved during the AML table load.
-
-Fields: Duplicate FieldUnit names within a scope are now detected
-during AML table load.
-
-Acpi Interfaces: Fixed a problem where the AcpiGetName() interface
-returned an incorrect name for the root node.
-
-Code and Data Size: Code and Data optimizations have permitted new
-feature development with an actual reduction in the library size.
-Current core subsystem library sizes are shown below. These are
-the code and data sizes for the acpica.lib produced by the
-Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code
-includes the debug output trace mechanism and has a larger code
-and data size. Note that these values will vary depending on the
-efficiency of the compiler and the compiler options used during
-generation.

-
-----------------------------------------
-Summary of changes for this label: 10_18_01
-
-ACPI CA Core Subsystem:
-
-Fixed a problem with the internal object reference count mechanism
-that occasionally caused premature object deletion. This resolves
-all of the outstanding problem reports where an object is deleted
-in the middle of an interpreter evaluation. Although this problem
-only showed up in rather obscure cases, the solution to the
-problem involved an adjustment of all reference counts involving
-objects attached to namespace nodes.
-
-Fixed a problem with Field support in the interpreter where
-writing to an aligned field whose length is an exact multiple (2
-or greater) of the field access granularity would cause an attempt
-to write beyond the end of the field.
-
-The top level AML opcode execution functions within the
-interpreter have been renamed with a more meaningful and
-consistent naming convention. The modules exmonad.c and
-exdyadic.c were eliminated. New modules are exoparg1.c,
-exoparg2.c, exoparg3.c, and exoparg6.c.
-
-Support for the ACPI 2.0 "Mid" ASL operator has been implemented.
-
-Fixed a problem where the AML debugger was causing some internal
-objects to not be deleted during subsystem termination.
-
-Fixed a problem with the external AcpiEvaluateObject interface
-where the subsystem would fault if the named object to be
-evaluated refered to a constant such as Zero, Ones, etc.
-
-Fixed a problem with IndexFields and BankFields where the
-subsystem would fault if the index, data, or bank registers were
-not defined in the same scope as the field itself.
-
-Added printf format string checking for compilers that support
-this feature. Corrected more than 50 instances of issues with
-format specifiers within invocations of ACPI_DEBUG_PRINT
-throughout the core subsystem code.
-
-The ASL "Revision" operator now returns the ACPI support level
-implemented in the core - the value "2" since the ACPI 2.0 support
-is more than 50% implemented.
-
-Enhanced the output of the AML debugger "dump namespace" command
-to output in a more human-readable form.
-
-Current core subsystem library code sizes are shown below. These
-
-are the code and data sizes for the acpica.lib produced by the
-Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code
-includes the full debug trace mechanism -- leading to a much
-
-larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-Linux:
-
-Implemented a "Bad BIOS Blacklist" to track machines that have
-known ASL/AML problems.
-
-Enhanced the /proc interface for the thermal zone driver and added
-support for _HOT (the critical suspend trip point). The 'info'
-file now includes threshold/policy information, and allows setting
-of _SCP (cooling preference) and _TZP (polling frequency) values
-to the 'info' file. Examples: "echo tzp=5 > info" sets the polling
-frequency to 5 seconds, and "echo scp=1 > info" sets the cooling
-preference to the passive/quiet mode (if supported by the ASL).
-
-Implemented a workaround for a gcc bug that resuted in an OOPs
-when loading the control method battery driver.
-
- ----------------------------------------
-Summary of changes for this label: 09_20_01
-
- ACPI CA Core Subsystem:
-
-The AcpiEnableEvent and AcpiDisableEvent interfaces have been
-modified to allow individual GPE levels to be flagged as wake-
-enabled (i.e., these GPEs are to remain enabled when the platform
-sleeps.)
-
-The AcpiEnterSleepState and AcpiLeaveSleepState interfaces now
-support wake-enabled GPEs. This means that upon entering the
-sleep state, all GPEs that are not wake-enabled are disabled.
-When leaving the sleep state, these GPEs are reenabled.
-
-A local double-precision divide/modulo module has been added to
-enhance portability to OS kernels where a 64-bit math library is
-not available. The new module is "utmath.c".
-
-Several optimizations have been made to reduce the use of CPU
-stack. Originally over 2K, the maximum stack usage is now below
-2K at 1860 bytes (1.82k)
-
-Fixed a problem with the AcpiGetFirmwareTable interface where the
-root table pointer was not mapped into a logical address properly.
-
-Fixed a problem where a NULL pointer was being dereferenced in the
-interpreter code for the ASL Notify operator.
-
-Fixed a problem where the use of the ASL Revision operator
-returned an error. This operator now returns the current version
-of the ACPI CA core subsystem.
-
-Fixed a problem where objects passed as control method parameters
-to AcpiEvaluateObject were always deleted at method termination.
-However, these objects may end up being stored into the namespace
-by the called method. The object reference count mechanism was
-applied to these objects instead of a force delete.
-
-Fixed a problem where static strings or buffers (contained in the
-AML code) that are declared as package elements within the ASL
-code could cause a fault because the interpreter would attempt to
-delete them. These objects are now marked with the "static
-object" flag to prevent any attempt to delete them.
-
-Implemented an interpreter optimization to use operands directly
-from the state object instead of extracting the operands to local
-variables. This reduces stack use and code size, and improves
-performance.
-
-The module exxface.c was eliminated as it was an unnecessary extra
-layer of code.
-
-Current core subsystem library code sizes are shown below. These
-are the code and data sizes for the acpica.lib produced by the
-Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code
-includes the full debug trace mechanism -- leading to a much
-larger code and data size. Note that these values will vary
-depending on the efficiency of the compiler and the compiler
-options used during generation.

-
-Linux:
-
-Support for ACPI 2.0 64-bit integers has been added. All ACPI
-Integer objects are now 64 bits wide
-
-All Acpi data types and structures are now in lower case. Only
-Acpi macros are upper case for differentiation.
-
- Documentation:
-
-Changes to the external interfaces as described above.
-
- ----------------------------------------
-Summary of changes for this label: 08_31_01
-
- ACPI CA Core Subsystem:
-
-A bug with interpreter implementation of the ASL Divide operator
-was found and fixed. The implicit function return value (not the
-explicit store operands) was returning the remainder instead of
-the quotient. This was a longstanding bug and it fixes several
-known outstanding issues on various platforms.
-
-The ACPI_DEBUG_PRINT and function trace entry/exit macros have
-been further optimized for size. There are 700 invocations of the
-DEBUG_PRINT macro alone, so each optimization reduces the size of
-the debug version of the subsystem significantly.
-
-A stack trace mechanism has been implemented. The maximum stack
-usage is about 2K on 32-bit platforms. The debugger command "stat
-stack" will display the current maximum stack usage.
-
-All public symbols and global variables within the subsystem are
-now prefixed with the string "Acpi". This keeps all of the
-symbols grouped together in a kernel map, and avoids conflicts
-with other kernel subsystems.
-
-Most of the internal fixed lookup tables have been moved into the
-code segment via the const operator.
-
-Several enhancements have been made to the interpreter to both
-reduce the code size and improve performance.
-
-Current core subsystem library code sizes are shown below. These
-are the code and data sizes for the acpica.lib produced by the
-Microsoft Visual C++ 6.0 compiler, and these values do not include
-any ACPI driver or OSPM code. The debug version of the code
-includes the full debug trace mechanism which contains over 700
-invocations of the DEBUG_PRINT macro, 500 function entry macro
-invocations, and over 900 function exit macro invocations --
-leading to a much larger code and data size. Note that these
-values will vary depending on the efficiency of the compiler and
-the compiler options used during generation.
-
- Non-Debug Version: 64K Code, 5K Data, 69K Total
-Debug Version: 137K Code, 58K Data, 195K Total
-
- Linux:
-
-Implemented wbinvd() macro, pending a kernel-wide definition.
-
-Fixed /proc/acpi/event to handle poll() and short reads.
-
- ASL Compiler, version X2026:
-
-Fixed a problem introduced in the previous label where the AML
-
-code emitted for package objects produced packages with zero
-length.
-
- ----------------------------------------
-Summary of changes for this label: 08_16_01
-
-ACPI CA Core Subsystem:
-
-The following ACPI 2.0 ASL operators have been implemented in the
-AML interpreter (These are already supported by the Intel ASL
-compiler): ToDecimalString, ToHexString, ToString, ToInteger, and
-ToBuffer. Support for 64-bit AML constants is implemented in the
-AML parser, debugger, and disassembler.
-
-The internal memory tracking mechanism (leak detection code) has
-been upgraded to reduce the memory overhead (a separate tracking
-block is no longer allocated for each memory allocation), and now
-supports all of the internal object caches.
-
-The data structures and code for the internal object caches have
-been coelesced and optimized so that there is a single cache and
-memory list data structure and a single group of functions that
-implement generic cache management. This has reduced the code
-size in both the debug and release versions of the subsystem.
-
-The DEBUG_PRINT macro(s) have been optimized for size and replaced
-by ACPI_DEBUG_PRINT. The syntax for this macro is slightly
-different, because it generates a single call to an internal
-function. This results in a savings of about 90 bytes per
-invocation, resulting in an overall code and data savings of about
-16% in the debug version of the subsystem.
-
- Linux:
-
-Fixed C3 disk corruption problems and re-enabled C3 on supporting
-machines.
-
-Integrated low-level sleep code by Patrick Mochel.
-
-Further tweaked source code Linuxization.
-
-Other minor fixes.
-
- ASL Compiler:
-
-Support for ACPI 2.0 variable length packages is fixed/completed.
-
-Fixed a problem where the optional length parameter for the ACPI
-2.0 ToString operator.
-
-Fixed multiple extraneous error messages when a syntax error is
-detected within the declaration line of a control method.
-
- ----------------------------------------
-Summary of changes for this label: 07_17_01
-
-ACPI CA Core Subsystem:
-
-Added a new interface named AcpiGetFirmwareTable to obtain any
-ACPI table via the ACPI signature. The interface can be called at
-any time during kernel initialization, even before the kernel
-virtual memory manager is initialized and paging is enabled. This
-allows kernel subsystems to obtain ACPI tables very early, even
-before the ACPI CA subsystem is initialized.
-
-Fixed a problem where Fields defined with the AnyAcc attribute
-could be resolved to the incorrect address under the following
-conditions: 1) the field width is larger than 8 bits and 2) the
-parent operation region is not defined on a DWORD boundary.
-
-Fixed a problem where the interpreter is not being locked during
-namespace initialization (during execution of the _INI control
-methods), causing an error when an attempt is made to release it
-later.
-
-ACPI 2.0 support in the AML Interpreter has begun and will be
-ongoing throughout the rest of this year. In this label, The Mod
-operator is implemented.
-
-Added a new data type to contain full PCI addresses named
-ACPI_PCI_ID. This structure contains the PCI Segment, Bus, Device,
-and Function values.
-
- Linux:
-
-Enhanced the Linux version of the source code to change most
-capitalized ACPI type names to lowercase. For example, all
-instances of ACPI_STATUS are changed to acpi_status. This will
-result in a large diff, but the change is strictly cosmetic and
-aligns the CA code closer to the Linux coding standard.
-
-OSL Interfaces:
-
-The interfaces to the PCI configuration space have been changed to
-add the PCI Segment number and to split the single 32-bit combined
-DeviceFunction field into two 16-bit fields. This was
-accomplished by moving the four values that define an address in
-PCI configuration space (segment, bus, device, and function) to
-the new ACPI_PCI_ID structure.
-
-The changes to the PCI configuration space interfaces led to a
-reexamination of the complete set of address space access
-interfaces for PCI, I/O, and Memory. The previously existing 18
-interfaces have proven difficult to maintain (any small change
-must be propagated across at least 6 interfaces) and do not easily
-allow for future expansion to 64 bits if necessary. Also, on some
-systems, it would not be appropriate to demultiplex the access
-width (8, 16, 32,or 64) before calling the OSL if the
-corresponding native OS interfaces contain a similar access width
-parameter. For these reasons, the 18 address space interfaces
-have been replaced by these 6 new ones:
-
-AcpiOsReadPciConfiguration
-AcpiOsWritePciConfiguration
-AcpiOsReadMemory
-AcpiOsWriteMemory
-AcpiOsReadPort
-AcpiOsWritePort
-
-Added a new interface named AcpiOsGetRootPointer to allow the OSL
-to perform the platform and/or OS-specific actions necessary to
-obtain the ACPI RSDP table pointer. On IA-32 platforms, this
-interface will simply call down to the CA core to perform the low-
-memory search for the table. On IA-64, the RSDP is obtained from
-EFI. Migrating this interface to the OSL allows the CA core to
-
-remain OS and platform independent.
-
-Added a new interface named AcpiOsSignal to provide a generic
-"function code and pointer" interface for various miscellaneous
-signals and notifications that must be made to the host OS. The
-first such signals are intended to support the ASL Fatal and
-Breakpoint operators. In the latter case, the AcpiOsBreakpoint
-interface has been obsoleted.
-
-The definition of the AcpiFormatException interface has been
-changed to simplify its use. The caller no longer must supply a
-buffer to the call; A pointer to a const string is now returned
-directly. This allows the call to be easily used in printf
-statements, etc. since the caller does not have to manage a local
-buffer.
-
-
- ASL Compiler, Version X2025:
-
-The ACPI 2.0 Switch/Case/Default operators have been implemented
-and are fully functional. They will work with all ACPI 1.0
-interpreters, since the operators are simply translated to If/Else
-pairs.
-
-The ACPI 2.0 ElseIf operator is implemented and will also work
-with 1.0 interpreters, for the same reason.
-
-Implemented support for ACPI 2.0 variable-length packages. These
-packages have a separate opcode, and their size is determined by
-the interpreter at run-time.
-
-Documentation The ACPI CA Programmer Reference has been updated to
-reflect the new interfaces and changes to existing interfaces.
-
- ------------------------------------------
-Summary of changes for this label: 06_15_01
-
- ACPI CA Core Subsystem:
-
-Fixed a problem where a DWORD-accessed field within a Buffer
-object would get its byte address inadvertently rounded down to
-the nearest DWORD. Buffers are always Byte-accessible.
-
- ASL Compiler, version X2024:
-
-Fixed a problem where the Switch() operator would either fault or
-hang the compiler. Note however, that the AML code for this ACPI
-2.0 operator is not yet implemented.
-
-Compiler uses the new AcpiOsGetTimer interface to obtain compile
-timings.
-
-Implementation of the CreateField operator automatically converts
-a reference to a named field within a resource descriptor from a
-byte offset to a bit offset if required.
-
-Added some missing named fields from the resource descriptor
-support. These are the names that are automatically created by the
-compiler to reference fields within a descriptor. They are only
-valid at compile time and are not passed through to the AML
-interpreter.
-
-Resource descriptor named fields are now typed as Integers and
-subject to compile-time typechecking when used in expressions.
-

-
- ACPI CA Core Subsystem:
-
-Fixed a couple of problems in the Field support code where bits
-from adjacent fields could be returned along with the proper field
-bits. Restructured the field support code to improve performance,
-readability and maintainability.
-
-New DEBUG_PRINTP macro automatically inserts the procedure name
-into the output, saving hundreds of copies of procedure name
-strings within the source, shrinking the memory footprint of the
-debug version of the core subsystem.
-
- Source Code Structure:
-
-The source code directory tree was restructured to reflect the
-current organization of the component architecture. Some files
-and directories have been moved and/or renamed.
-

-
-Fixed queueing event data even when /proc/acpi/event is not
-opened.
-
- ASL Compiler, version X2020:
-
-Memory allocation performance enhancement - over 24X compile time
-improvement on large ASL files. Parse nodes and namestring
-buffers are now allocated from a large internal compiler buffer.
-
-The temporary .SRC file is deleted unless the "-s" option is
-specified
-
-The "-d" debug output option now sends all output to the .DBG file
-instead of the console.
-
-"External" second parameter is now optional
-
-"ElseIf" syntax now properly allows the predicate
-
-Last operand to "Load" now recognized as a Target operand
-
-Debug object can now be used anywhere as a normal object.
-
-ResourceTemplate now returns an object of type BUFFER
-
-EISAID now returns an object of type INTEGER
-
-"Index" now works with a STRING operand
-
-"LoadTable" now accepts optional parameters
-
-"ToString" length parameter is now optional
-
-"Interrupt (ResourceType," parse error fixed.
-
-"Register" with a user-defined region space parse error fixed
-
-Escaped backslash at the end of a string ("\\") scan/parse error
-fixed
-
-"Revision" is now an object of type INTEGER.

-Removed /proc/sys/acpi. You can still dump your DSDT from
-/proc/acpi/dsdt.
-
- ACPI CA Core Subsystem:
-
-Fixed a problem introduced in the previous label where some of the
-"small" resource descriptor types were not recognized.
-
-Improved error messages for the case where an ASL Field is outside
-the range of the parent operation region.
-
- ASL Compiler, version X2018:
-
-
-Added error detection for ASL Fields that extend beyond the length
-of the parent operation region (only if the length of the region
-is known at compile time.) This includes fields that have a
-minimum access width that is smaller than the parent region, and
-individual field units that are partially or entirely beyond the
-extent of the parent.
-
-
-
-------------------------------------------
-Summary of changes for this label: 04_27_01
-
- ACPI CA Core Subsystem:
-
-Fixed a problem where the namespace mutex could be released at the
-wrong time during execution of AcpiRemoveAddressSpaceHandler.
-
-Added optional thread ID output for debug traces, to simplify
-debugging of multiple threads. Added context switch notification
-when the debug code realizes that a different thread is now
-executing ACPI code.
-
-Some additional external data types have been prefixed with the
-string "ACPI_" for consistency. This may effect existing code.
-The data types affected are the external callback typedefs - e.g.,
-
-WALK_CALLBACK becomes ACPI_WALK_CALLBACK.
-
- Linux:
-
-Fixed an issue with the OSL semaphore implementation where a
-thread was waking up with an error from receiving a SIGCHLD
-signal.
-
-Linux version of ACPI CA now uses the system C library for string
-manipulation routines instead of a local implementation.
-
-Cleaned up comments and removed TBDs.
-
- ASL Compiler, version X2017:
-
-Enhanced error detection and reporting for all file I/O
-operations.
-
- Documentation:
-
-Programmer Reference updated to version 1.06.
-
-
-
-------------------------------------------
-Summary of changes for this label: 04_13_01
-
- ACPI CA Core Subsystem:
-
-Restructured support for BufferFields and RegionFields.
-BankFields support is now fully operational. All known 32-bit
-limitations on field sizes have been removed. Both BufferFields
-and (Operation) RegionFields are now supported by the same field
-management code.
-
-Resource support now supports QWORD address and IO resources. The
-16/32/64 bit address structures and the Extended IRQ structure
-have been changed to properly handle Source Resource strings.
-
-A ThreadId of -1 is now used to indicate a "mutex not acquired"
-condition internally and must never be returned by AcpiOsThreadId.
-This reserved value was changed from 0 since Unix systems allow a
-thread ID of 0.
-
-Linux:
-
-Driver code reorganized to enhance portability
-
-Added a kernel configuration option to control ACPI_DEBUG
-
-Fixed the EC driver to honor _GLK.
-
-ASL Compiler, version X2016:
-
-Fixed support for the "FixedHw" keyword. Previously, the FixedHw
-address space was set to 0, not 0x7f as it should be.
-
- ------------------------------------------
-Summary of changes for this label: 03_13_01
-
- ACPI CA Core Subsystem:
-
-During ACPI initialization, the _SB_._INI method is now run if
-present.
-
-Notify handler fix - notifies are deferred until the parent method
-completes execution. This fixes the "mutex already acquired"
-issue seen occasionally.
-
-Part of the "implicit conversion" rules in ACPI 2.0 have been
-found to cause compatibility problems with existing ASL/AML. The
-convert "result-to-target-type" implementation has been removed
-for stores to method Args and Locals. Source operand conversion
-is still fully implemented. Possible changes to ACPI 2.0
-specification pending.
-
-Fix to AcpiRsCalculatePciRoutingTableLength to return correct
-length.
-
-Fix for compiler warnings for 64-bit compiles.
-
- Linux:
-
-/proc output aligned for easier parsing.
-
-Release-version compile problem fixed.
-
-New kernel configuration options documented in Configure.help.
-
-IBM 600E - Fixed Sleep button may generate "Invalid <NULL>
-context" message.
-
- OSPM:
-
-Power resource driver integrated with bus manager.
-
-Fixed kernel fault during active cooling for thermal zones.
-
-Source Code:
-
-The source code tree has been restructured.
-
-
-
-------------------------------------------
-Summary of changes for this label: 03_02_01
-
- Linux OS Services Layer (OSL):
-
-Major revision of all Linux-specific code.
-
-Modularized all ACPI-specific drivers.
-
-Added new thermal zone and power resource drivers.
-
-Revamped /proc interface (new functionality is under /proc/acpi).
-
-New kernel configuration options.
-
- Linux known issues:
-
-New kernel configuration options not documented in Configure.help
-yet.
-
-
-Module dependencies not currently implemented. If used, they
-should be loaded in this order: busmgr, power, ec, system,
-processor, battery, ac_adapter, button, thermal.
-
-Modules will not load if CONFIG_MODVERSION is set.
-
-IBM 600E - entering S5 may reboot instead of shutting down.
-
-IBM 600E - Sleep button may generate "Invalid <NULL> context"
-message.
-
-Some systems may fail with "execution mutex already acquired"
-message.
-
- ACPI CA Core Subsystem:
-
-Added a new OSL Interface, AcpiOsGetThreadId. This was required
-for the deadlock detection code. Defined to return a non-zero, 32-
-bit thread ID for the currently executing thread. May be a non-
-zero constant integer on single-thread systems.
-
-Implemented deadlock detection for internal subsystem mutexes. We
-may add conditional compilation for this code (debug only) later.
-
-ASL/AML Mutex object semantics are now fully supported. This
-includes multiple acquires/releases by owner and support for the
-
-Mutex SyncLevel parameter.
-
-A new "Force Release" mechanism automatically frees all ASL
-Mutexes that have been acquired but not released when a thread
-exits the interpreter. This forces conformance to the ACPI spec
-("All mutexes must be released when an invocation exits") and
-prevents deadlocked ASL threads. This mechanism can be expanded
-(later) to monitor other resource acquisitions if OEM ASL code
-continues to misbehave (which it will).
-
-Several new ACPI exception codes have been added for the Mutex
-support.
-
-Recursive method calls are now allowed and supported (the ACPI
-spec does in fact allow recursive method calls.) The number of
-recursive calls is subject to the restrictions imposed by the
-SERIALIZED method keyword and SyncLevel (ACPI 2.0) method
-parameter.
-
-Implemented support for the SyncLevel parameter for control
-methods (ACPI 2.0 feature)
-
-Fixed a deadlock problem when multiple threads attempted to use
-the interpreter.
-
-Fixed a problem where the string length of a String package
-element was not always set in a package returned from
-AcpiEvaluateObject.
-
-Fixed a problem where the length of a String package element was
-not always included in the length of the overall package returned
-from AcpiEvaluateObject.
-
-Added external interfaces (Acpi*) to the ACPI debug memory
-manager. This manager keeps a list of all outstanding
-allocations, and can therefore detect memory leaks and attempts to
-free memory blocks more than once. Useful for code such as the
-power manager, etc. May not be appropriate for device drivers.
-Performance with the debug code enabled is slow.
-
-The ACPI Global Lock is now an optional hardware element.
-
- ASL Compiler Version X2015:
-
-Integrated changes to allow the compiler to be generated on
-multiple platforms.
-
-Linux makefile added to generate the compiler on Linux
-
- Source Code:
-
-All platform-specific headers have been moved to their own
-subdirectory, Include/Platform.
-
-New source file added, Interpreter/ammutex.c
-
-New header file, Include/acstruct.h
-
- Documentation:
-
-The programmer reference has been updated for the following new
-interfaces: AcpiOsGetThreadId AcpiAllocate AcpiCallocate AcpiFree
-
- ------------------------------------------
-Summary of changes for this label: 02_08_01
-
-Core ACPI CA Subsystem: Fixed a problem where an error was
-incorrectly returned if the return resource buffer was larger than
-the actual data (in the resource interfaces).
-
-References to named objects within packages are resolved to the
-
-full pathname string before packages are returned directly (via
-the AcpiEvaluateObject interface) or indirectly via the resource
-interfaces.
-
-Linux OS Services Layer (OSL):
-
-Improved /proc battery interface.
-
-
-Added C-state debugging output and other miscellaneous fixes.
-
-ASL Compiler Version X2014:
-
-All defined method arguments can now be used as local variables,
-including the ones that are not actually passed in as parameters.
-The compiler tracks initialization of the arguments and issues an
-exception if they are used without prior assignment (just like
-locals).
-
-The -o option now specifies a filename prefix that is used for all
-output files, including the AML output file. Otherwise, the
-default behavior is as follows: 1) the AML goes to the file
-specified in the DSDT. 2) all other output files use the input
-source filename as the base.
-
- ------------------------------------------
-Summary of changes for this label: 01_25_01
-
-Core ACPI CA Subsystem: Restructured the implementation of object
-store support within the interpreter. This includes support for
-the Store operator as well as any ASL operators that include a
-target operand.
-
-Partially implemented support for Implicit Result-to-Target
-conversion. This is when a result object is converted on the fly
-to the type of an existing target object. Completion of this
-support is pending further analysis of the ACPI specification
-concerning this matter.
-
-CPU-specific code has been removed from the subsystem (hardware
-directory).
-
-New Power Management Timer functions added
-
-Linux OS Services Layer (OSL): Moved system state transition code
-to the core, fixed it, and modified Linux OSL accordingly.
-
-Fixed C2 and C3 latency calculations.
-
-
-We no longer use the compilation date for the version message on
-initialization, but retrieve the version from AcpiGetSystemInfo().
-
-Incorporated for fix Sony VAIO machines.
-
-Documentation: The Programmer Reference has been updated and
-reformatted.
-
-
-ASL Compiler: Version X2013: Fixed a problem where the line
-numbering and error reporting could get out of sync in the
-presence of multiple include files.
-
- ------------------------------------------
-Summary of changes for this label: 01_15_01
-
-Core ACPI CA Subsystem:
-
-Implemented support for type conversions in the execution of the
-ASL Concatenate operator (The second operand is converted to
-match the type of the first operand before concatenation.)
-
-Support for implicit source operand conversion is partially
-implemented. The ASL source operand types Integer, Buffer, and
-String are freely interchangeable for most ASL operators and are
-converted by the interpreter on the fly as required. Implicit
-Target operand conversion (where the result is converted to the
-target type before storing) is not yet implemented.
-
-Support for 32-bit and 64-bit BCD integers is implemented.
-
-Problem fixed where a field read on an aligned field could cause a
-read past the end of the field.
-
-New exception, AE_AML_NO_RETURN_VALUE, is returned when a method
-does not return a value, but the caller expects one. (The ASL
-compiler flags this as a warning.)
-
-ASL Compiler:
-
-Version X2011:
-1. Static typechecking of all operands is implemented. This
-prevents the use of invalid objects (such as using a Package where
-an Integer is required) at compile time instead of at interpreter
-run-time.
-2. The ASL source line is printed with ALL errors and warnings.
-3. Bug fix for source EOF without final linefeed.
-4. Debug option is split into a parse trace and a namespace trace.
-5. Namespace output option (-n) includes initial values for
-integers and strings.
-6. Parse-only option added for quick syntax checking.
-7. Compiler checks for duplicate ACPI name declarations
-
-Version X2012:
-1. Relaxed typechecking to allow interchangeability between
-strings, integers, and buffers. These types are now converted by
-the interpreter at runtime.
-2. Compiler reports time taken by each internal subsystem in the
-debug output file.
-
-
- ------------------------------------------
-Summary of changes for this label: 12_14_00
-
-ASL Compiler:
-
-This is the first official release of the compiler. Since the
-compiler requires elements of the Core Subsystem, this label
-synchronizes everything.
-
-------------------------------------------
-Summary of changes for this label: 12_08_00
-
-
-Fixed a problem where named references within the ASL definition
-of both OperationRegions and CreateXXXFields did not work
-properly. The symptom was an AE_AML_OPERAND_TYPE during
-initialization of the region/field. This is similar (but not
-related internally) to the problem that was fixed in the last
-label.
-
-Implemented both 32-bit and 64-bit support for the BCD ASL
-functions ToBCD and FromBCD.
-
-Updated all legal headers to include "2000" in the copyright
-years.
-
- ------------------------------------------
-Summary of changes for this label: 12_01_00
-
-Fixed a problem where method invocations within the ASL definition
-of both OperationRegions and CreateXXXFields did not work
-properly. The symptom was an AE_AML_OPERAND_TYPE during
-initialization of the region/field:
-
- nsinit-0209: AE_AML_OPERAND_TYPE while getting region arguments
-[DEBG] ammonad-0284: Exec_monadic2_r/Not: bad operand(s)
-(0x3005)
-
-Fixed a problem where operators with more than one nested
-subexpression would fail. The symptoms were varied, by mostly
-AE_AML_OPERAND_TYPE errors. This was actually a rather serious
-problem that has gone unnoticed until now.
-
- Subtract (Add (1,2), Multiply (3,4))
-
-Fixed a problem where AcpiGetHandle didn't quite get fixed in the
-previous build (The prefix part of a relative path was handled
-incorrectly).
-
-Fixed a problem where Operation Region initialization failed if
-the operation region name was a "namepath" instead of a simple
-"nameseg". Symptom was an AE_NO_OPERAND error.
-
-Fixed a problem where an assignment to a local variable via the
-indirect RefOf mechanism only worked for the first such
-assignment. Subsequent assignments were ignored.
-
- ------------------------------------------
-Summary of changes for this label: 11_15_00
-
-ACPI 2.0 table support with backwards support for ACPI 1.0 and the
-0.71 extensions. Note: although we can read ACPI 2.0 BIOS tables,
-the AML interpreter does NOT have support for the new 2.0 ASL
-grammar terms at this time.
-
-All ACPI hardware access is via the GAS structures in the ACPI 2.0
-FADT.
-
-All physical memory addresses across all platforms are now 64 bits
-wide. Logical address width remains dependent on the platform
-(i.e., "void *").
-
-AcpiOsMapMemory interface changed to a 64-bit physical address.
-
-The AML interpreter integer size is now 64 bits, as per the ACPI
-2.0 specification.
-
-For backwards compatibility with ACPI 1.0, ACPI tables with a
-revision number less than 2 use 32-bit integers only.
-
-Fixed a problem where the evaluation of OpRegion operands did not
-always resolve them to numbers properly.
-
-------------------------------------------
-Summary of changes for this label: 10_20_00
-
-Fix for CBN_._STA issue. This fix will allow correct access to
-CBN_ OpRegions when the _STA returns 0x8.
-
-Support to convert ACPI constants (Ones, Zeros, One) to actual
-values before a package object is returned
-
-Fix for method call as predicate to if/while construct causing
-incorrect if/while behavior
-
-Fix for Else block package lengths sometimes calculated wrong (if
-block > 63 bytes)
-
-Fix for Processor object length field, was always zero
-
-Table load abort if FACP sanity check fails
-
-Fix for problem with Scope(name) if name already exists
-
-Warning emitted if a named object referenced cannot be found
-(resolved) during method execution.
-
-
-
-
-
-------------------------------------------
-Summary of changes for this label: 9_29_00
-
-New table initialization interfaces: AcpiInitializeSubsystem no
-longer has any parameters AcpiFindRootPointer - Find the RSDP (if
-necessary) AcpiLoadTables (RSDP) - load all tables found at RSDP-
->RSDT Obsolete Interfaces AcpiLoadFirmwareTables - replaced by
-AcpiLoadTables
-
-Note: These interface changes require changes to all existing OSDs
-
-The PCI_Config default address space handler is always installed
-at the root namespace object.
-
--------------------------------------------
-Summary of changes for this label: 09_15_00
-
-The new initialization architecture is implemented. New
-interfaces are: AcpiInitializeSubsystem (replaces AcpiInitialize)
-AcpiEnableSubsystem Obsolete Interfaces: AcpiLoadNamespace
-
-(Namespace is automatically loaded when a table is loaded)
-
-The ACPI_OPERAND_OBJECT has been optimized to shrink its size from
-52 bytes to 32 bytes. There is usually one of these for every
-namespace object, so the memory savings is significant.
-
-Implemented just-in-time evaluation of the CreateField operators.
-
-Bug fixes for IA-64 support have been integrated.
-
-Additional code review comments have been implemented
-
-The so-called "third pass parse" has been replaced by a final walk
-through the namespace to initialize all operation regions (address
-spaces) and fields that have not yet been initialized during the
-execution of the various _INI and REG methods.
-
-New file - namespace/nsinit.c
-
--------------------------------------------
-Summary of changes for this label: 09_01_00
-
-Namespace manager data structures have been reworked to change the
-primary object from a table to a single object. This has
-resulted in dynamic memory savings of 3X within the namespace and
-2X overall in the ACPI CA subsystem.
-
-Fixed problem where the call to AcpiEvFindPciRootBuses was
-inadvertently left commented out.
-
-Reduced the warning count when generating the source with the GCC
-compiler.
-
-Revision numbers added to each module header showing the
-SourceSafe version of the file. Please refer to this version
-number when giving us feedback or comments on individual modules.
-
-The main object types within the subsystem have been renamed to
-clarify their purpose:
-
-ACPI_INTERNAL_OBJECT -> ACPI_OPERAND_OBJECT
-ACPI_GENERIC_OP -> ACPI_PARSE_OBJECT
-ACPI_NAME_TABLE_ENTRY -> ACPI_NAMESPACE_NODE
-
-NOTE: no changes to the initialization sequence are included in
-this label.
-
--------------------------------------------
-Summary of changes for this label: 08_23_00
-
-Fixed problem where TerminateControlMethod was being called
-multiple times per method
-
-Fixed debugger problem where single stepping caused a semaphore to
-be oversignalled
-
-Improved performance through additional parse object caching -
-added ACPI_EXTENDED_OP type
-
--------------------------------------------
-Summary of changes for this label: 08_10_00
-
-Parser/Interpreter integration: Eliminated the creation of
-complete parse trees for ACPI tables and control methods.
-Instead, parse subtrees are created and then deleted as soon as
-they are processed (Either entered into the namespace or executed
-by the interpreter). This reduces the use of dynamic kernel
-memory significantly. (about 10X)
-
-Exception codes broken into classes and renumbered. Be sure to
-recompile all code that includes acexcep.h. Hopefully we won't
-have to renumber the codes again now that they are split into
-classes (environment, programmer, AML code, ACPI table, and
-internal).
-
-Fixed some additional alignment issues in the Resource Manager
-subcomponent
-
-Implemented semaphore tracking in the AcpiExec utility, and fixed
-several places where mutexes/semaphores were being unlocked
-without a corresponding lock operation. There are no known
-semaphore or mutex "leaks" at this time.
-
-Fixed the case where an ASL Return operator is used to return an
-unnamed package.
-
--------------------------------------------
-Summary of changes for this label: 07_28_00
-
-Fixed a problem with the way addresses were calculated in
-AcpiAmlReadFieldData() and AcpiAmlWriteFieldData(). This problem
-manifested itself when a Field was created with WordAccess or
-DwordAccess, but the field unit defined within the Field was less
-
-than a Word or Dword.
-
-Fixed a problem in AmlDumpOperands() module's loop to pull
-operands off of the operand stack to display information. The
-problem manifested itself as a TLB error on 64-bit systems when
-accessing an operand stack with two or more operands.
-
-Fixed a problem with the PCI configuration space handlers where
-context was getting confused between accesses. This required a
-change to the generic address space handler and address space
-setup definitions. Handlers now get both a global handler context
-(this is the one passed in by the user when executing
-AcpiInstallAddressSpaceHandler() and a specific region context
-that is unique to each region (For example, the _ADR, _SEG and
-_BBN values associated with a specific region). The generic
-function definitions have changed to the following:
-
-typedef ACPI_STATUS (*ADDRESS_SPACE_HANDLER) ( UINT32 Function,
-UINT32 Address, UINT32 BitWidth, UINT32 *Value, void
-*HandlerContext, // This used to be void *Context void
-*RegionContext); // This is an additional parameter
-
-typedef ACPI_STATUS (*ADDRESS_SPACE_SETUP) ( ACPI_HANDLE
-RegionHandle, UINT32 Function, void *HandlerContext, void
-**RegionContext); // This used to be **ReturnContext
-
--------------------------------------------
-Summary of changes for this label: 07_21_00
-
-Major file consolidation and rename. All files within the
-interpreter have been renamed as well as most header files. This
-was done to prevent collisions with existing files in the host
-OSs -- filenames such as "config.h" and "global.h" seem to be
-quite common. The VC project files have been updated. All
-makefiles will require modification.
-
-The parser/interpreter integration continues in Phase 5 with the
-implementation of a complete 2-pass parse (the AML is parsed
-twice) for each table; This avoids the construction of a huge
-parse tree and therefore reduces the amount of dynamic memory
-required by the subsystem. Greater use of the parse object cache
-means that performance is unaffected.
-
-Many comments from the two code reviews have been rolled in.
-
-The 64-bit alignment support is complete.
-
--------------------------------------------
-Summary of changes for this label: 06_30_00
-
-With a nod and a tip of the hat to the technology of yesteryear,
-we've added support in the source code for 80 column output
-devices. The code is now mostly constrained to 80 columns or
-less to support environments and editors that 1) cannot display
-or print more than 80 characters on a single line, and 2) cannot
-disable line wrapping.
-
-A major restructuring of the namespace data structure has been
-completed. The result is 1) cleaner and more
-understandable/maintainable code, and 2) a significant reduction
-in the dynamic memory requirement for each named ACPI object
-(almost half).
-
--------------------------------------------
-Summary of changes for this label: 06_23_00
-
-Linux support has been added. In order to obtain approval to get
-the ACPI CA subsystem into the Linux kernel, we've had to make
-quite a few changes to the base subsystem that will affect all
-users (all the changes are generic and OS- independent). The
-effects of these global changes have been somewhat far reaching.
-Files have been merged and/or renamed and interfaces have been
-renamed. The major changes are described below.
-
-Osd* interfaces renamed to AcpiOs* to eliminate namespace
-pollution/confusion within our target kernels. All OSD
-interfaces must be modified to match the new naming convention.
-
-Files merged across the subsystem. A number of the smaller source
-and header files have been merged to reduce the file count and
-increase the density of the existing files. There are too many
-to list here. In general, makefiles that call out individual
-files will require rebuilding.
-
-Interpreter files renamed. All interpreter files now have the
-prefix am* instead of ie* and is*.
-
-Header files renamed: The acapi.h file is now acpixf.h. The
-acpiosd.h file is now acpiosxf.h. We are removing references to
-the acronym "API" since it is somewhat windowsy. The new name is
-"external interface" or xface or xf in the filenames.j
-
-
-All manifest constants have been forced to upper case (some were
-mixed case.) Also, the string "ACPI_" has been prepended to many
-(not all) of the constants, typedefs, and structs.
-
-The globals "DebugLevel" and "DebugLayer" have been renamed
-"AcpiDbgLevel" and "AcpiDbgLayer" respectively.
-
-All other globals within the subsystem are now prefixed with
-"AcpiGbl_" Internal procedures within the subsystem are now
-prefixed with "Acpi" (with only a few exceptions). The original
-two-letter abbreviation for the subcomponent remains after "Acpi"
-- for example, CmCallocate became AcpiCmCallocate.
-
-Added a source code translation/conversion utility. Used to
-generate the Linux source code, it can be modified to generate
-other types of source as well. Can also be used to cleanup
-existing source by removing extraneous spaces and blank lines.
-Found in tools/acpisrc/*
-
-OsdUnMapMemory was renamed to OsdUnmapMemory and then
-AcpiOsUnmapMemory. (UnMap became Unmap).
-
-A "MaxUnits" parameter has been added to AcpiOsCreateSemaphore.
-When set to one, this indicates that the caller wants to use the
-
-semaphore as a mutex, not a counting semaphore. ACPI CA uses
-both types. However, implementers of this call may want to use
-different OS primitives depending on the type of semaphore
-requested. For example, some operating systems provide separate
-
-"mutex" and "semaphore" interfaces - where the mutex interface is
-much faster because it doesn't have all the overhead of a full
-semaphore implementation.
-
-Fixed a deadlock problem where a method that accesses the PCI
-address space can block forever if it is the first access to the
-space.
-
--------------------------------------------
-Summary of changes for this label: 06_02_00
-
-Support for environments that cannot handle unaligned data
-accesses (e.g. firmware and OS environments devoid of alignment
-handler technology namely SAL/EFI and the IA-64 Linux kernel) has
-been added (via configurable macros) in these three areas: -
-Transfer of data from the raw AML byte stream is done via byte
-moves instead of word/dword/qword moves. - External objects are
-aligned within the user buffer, including package elements (sub-
-objects). - Conversion of name strings to UINT32 Acpi Names is now
-done byte-wise.
-
-The Store operator was modified to mimic Microsoft's
-implementation when storing to a Buffer Field.
-
-Added a check of the BM_STS bit before entering C3.
-
-The methods subdirectory has been obsoleted and removed. A new
-file, cmeval.c subsumes the functionality.
-
-A 16-bit (DOS) version of AcpiExec has been developed. The
-makefile is under the acpiexec directory.

- *
- * PARAMETERS: StartTicks - Starting timestamp

- * RETURN: Status and TimeElapsed
- *
- * DESCRIPTION: Computes the time elapsed (in microseconds) between two
- * PM Timer time stamps, taking into account the possibility of
- * rollovers, the timer resolution, and timer frequency.
- *
- * The PM Timer's clock ticks at roughly 3.6 times per
- * _microsecond_, and its clock continues through Cx state
- * transitions (unlike many CPU timestamp counters) -- making it
- * a versatile and accurate timer.
- *
- * Note that this function accommodates only a single timer
- * rollover. Thus for 24-bit timers, this function should only
- * be used for calculating durations less than ~4.6 seconds
- * (~20 minutes for 32-bit timers) -- calculations below:
- *
- * 2**24 Ticks / 3,600,000 Ticks/Sec = 4.66 sec
- * 2**32 Ticks / 3,600,000 Ticks/Sec = 1193 sec or 19.88 minutes

- * There are several areas that are validated:
- *
- * 1) The number of input arguments as defined by the method/object in the
- * ASL is validated against the ACPI specification.
- * 2) The type of the return object (if any) is validated against the ACPI
- * specification.
- * 3) For returned package objects, the count of package elements is
- * validated, as well as the type of each package element. Nested
- * packages are supported.
- *
- * For any problems found, a warning message is issued.
