+ Linux CAN Driver (LinCAN) version 0.3

lincan-0.2 version tested on many bords and 2.2, 2.4, 2.6 Linux
(Mar 2004) and RT-Linux enabled 2.4 Linux kernel
+lincan-0.2.8 possible SMP and HT deadlock fixed, driver can take
+(Jul 2004) advantage of CMPXCHG instruction if present on CPU,
+ added support for CPC-PCI and PCAN-PCI cards,
+ messages timestamping implemented
+ partially implemented support for Bosch C_CAN module,
+ requires more work and real hardware
+
+lincan-0.3 Changed SJA1000 chip IRQ handling. Enhanced VME
+(Nov 2004) and EMS CPC-PCI support and many other changes.
+
The actual version of driver have been latest tested it with
- PC104 Advantech PCM3680 dual channel board on 2.4 RT-Linux enabled kernel
- PiKRON ISA card on 2.4.and 2.6 Linux kernels
- BfaD DIMM PC card on 2.4 RT-Linux enabled kernel
- KVASER pcican-q on 2.6 Linux kernel
- MICROSPACE msmcan on 2.4 Linux and RT-Linux enabled kernel
- - virtual board tested on all systems as well
-It takes more time to test it with more cards and polish
-support for 2.2 and 2.6 kernels, but these should be mainly
-cosmetic changes (I hope ;-), infrastructure and original
-support for more than 17 boards with more variants is in.
+ - Unicontrols PCAN ("unican"),PCAN-PCI ("unican-pci"), VCAN ("unican-vme")
+ - EMS CPC-PCI cards ("ems_cpcpci")
+ - virtual board tested on all systems as wel
+It takes more time to test driver with more cards.
+Infrastructure and support for more than 20 boards with more
+variants is prepared in the sources.

-COMPILATION
-===========

+COMPILATION of LinCAN releases
+==============================
Just type 'make' at the command line and driver module should compile
-without errors for current running kernel.

+
+Some releases use experimental OMK make system, which requires
+recent GNU make program version 3.81beta1 and above.
+Makefiles can be switched to old ones by script
+
+ sh ./switch-omk2std
+ make
+
+If you have problem to obtain recent GNU make program,

+
+The selection of required features and options can be specified before make
+command invocation. Lines containing required changes to config.omk-default
+file should be stored in config.omk file. The config.omk is not altered by
+OMK system and options defined there override values defined in
+config.omk-default file. GNU make program version 3.81beta1 or newer is
+required by OMK make-system. If this is problem, LinCAN driver can be
+compiled with use of old style Makefiles as well.

INSTALLATION
============
-Type 'make install'. The driver should be copied into actual kernel version
+Type 'make install' for standard make system compilation.
+The driver should be copied into actual kernel version
modules directory "/lib/modules/x.y.z/kernel/drivers/char".
+OMK system requires manual copy of files from "_compiled" tree
+to its final destinations.
+
LOADING
=======
To load the driver type:
# insmod can.o hw='your hardware' irq='irq number' io='io address' <options>
-Example: # insmod can.o hw=pip5 irq=4 io=0x8000
+Examples: # insmod can.o hw=pip5 irq=4 io=0x8000
+ # insmod can.o hw=virtual io=0
The hw argument can be one of:
-- pip5, for the pip5 computer by MPL
-- pip6, for the pip6 computer by MPL
+- pip5, for the PIP5 computer by MPL
+- pip6, for the PIP6 computer by MPL
+- pip7, for the PIP7 computer by MPL
+- pip8, for the PIP8 computer by MPL
- pccan-q, for the PCcan-Q ISA card by KVASER
- pccan-f, for the PCcan-F ISA card by KVASER
- pccan-s, for the PCcan-S ISA card by KVASER
- bfadcan for sja1000 CAN embedded card made by BFAD GmbH
- pikronisa for ISA memory mapped sja1000 CAN card made by PiKRON Ltd.
- msmcan for MICROSPACE IO space indexed i82527
+- unican for Unicontrols PCAN card
+- unican-pci for Unicontrols PCAN-PCI card
+- unican-vme for Unicontrols VCAN card
+- ems_cpcpci for EMS CPC-PCI card
+- pcan_dongle for PEAK's printer port dongle addapter
+- oscar for SJA1000 based card connected to ARM LH7A400 SoC
- template, for yet unsupported hardware (you need to edit src/template.c)
- virtual, CAN channel for testing of software and driver without CAN hardware
- stdmask=<nr>, sets the standard mask of the device
- extmask=<nr>, sets the extended mask of the device
- mo15mask=<nr>, sets the mask for message object 15 (i82527 only)
+- processlocal=<nr>, controls distribution of send messages to Rx FIFOs
+ 0, no local outgoing messages delivery to Rx FIFOs
+ 1, default off, but can be controlled by individual filter settings
+ 2, all FIFOs receive local messages
There's still a lot of work to do, have a look at the TODO file for more
information.
