639 bool "kexec system call (EXPERIMENTAL)"
640 depends on SUPERH32 && MMU
642 kexec is a system call that implements the ability to shutdown your
643 current kernel, and to start another kernel. It is like a reboot
644 but it is independent of the system firmware. And like a reboot
645 you can start any kernel with it, not just Linux.
647 The name comes from the similarity to the exec system call.
649 It is an ongoing process to be certain the hardware in a machine
650 is properly shutdown, so do not be surprised if this code does not
651 initially work for you. It may help to enable device hotplugging
652 support. As of this writing the exact hardware interface is
653 strongly in flux, so no good recommendation can be made.
656 bool "kernel crash dumps (EXPERIMENTAL)"
657 depends on SUPERH32 && BROKEN_ON_SMP
659 Generate crash dump after being started by kexec.
660 This should be normally only set in special crash dump kernels
661 which are loaded in the main kernel with kexec-tools into
662 a specially reserved region and then later executed after
663 a crash by kdump/kexec. The crash dump kernel must be compiled
664 to a memory address not used by the main kernel using
667 For more details see Documentation/kdump/kdump.txt

676 config PHYSICAL_START
677 hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
680 This gives the physical address where the kernel is loaded
681 and is ordinarily the same as MEMORY_START.
683 Different values are primarily used in the case of kexec on panic
684 where the fail safe kernel needs to run at a different address
685 than the panic-ed kernel.
688 bool "Enable seccomp to safely compute untrusted bytecode"
691 This kernel feature is useful for number crunching applications
692 that may need to compute untrusted bytecode during their
693 execution. By using pipes or other transports made available to
694 the process as file descriptors supporting the read/write
695 syscalls, it's possible to isolate those applications in
696 their own address space using seccomp. Once seccomp is
697 enabled via prctl, it cannot be disabled and the task is only
698 allowed to execute a few safe syscalls defined by each seccomp
703 config CC_STACKPROTECTOR
704 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
707 This option turns on the -fstack-protector GCC feature. This
708 feature puts, at the beginning of functions, a canary value on
709 the stack just before the return address, and validates
710 the value just before actually returning. Stack based buffer
711 overflows (that need to overwrite this return address) now also
712 overwrite the canary, which gets detected and the attack is then
713 neutralized via a kernel panic.
715 This feature requires gcc version 4.2 or above.
718 bool "Symmetric multi-processing support"
719 depends on SYS_SUPPORTS_SMP
720 select USE_GENERIC_SMP_HELPERS
722 This enables support for systems with more than one CPU. If you have
723 a system with only one CPU, like most personal computers, say N. If
724 you have a system with more than one CPU, say Y.
726 If you say N here, the kernel will run on single and multiprocessor
727 machines, but will use only one CPU of a multiprocessor machine. If
728 you say Y here, the kernel will run on many, but not all,
729 singleprocessor machines. On a singleprocessor machine, the kernel
730 will run faster if you say N here.
732 People using multiprocessor machines who say Y here should also say
733 Y to "Enhanced Real Time Clock Support", below.
735 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
736 available at <http://www.tldp.org/docs.html#howto>.
738 If you don't know what to do here, say N.
741 int "Maximum number of CPUs (2-32)"
744 default "4" if CPU_SUBTYPE_SHX3
747 This allows you to specify the maximum number of CPUs which this
748 kernel will support. The maximum supported value is 32 and the
749 minimum value which makes sense is 2.
751 This is purely to save memory - each supported CPU adds
752 approximately eight kilobytes to the kernel image.
755 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"
756 depends on SMP && HOTPLUG
758 Say Y here to experiment with turning CPUs off and on. CPUs
759 can be controlled through /sys/devices/system/cpu.
761 source "kernel/Kconfig.preempt"

767 This enables support for gUSA (general UserSpace Atomicity).
768 This is the default implementation for both UP and non-ll/sc
769 CPUs, and is used by the libc, amongst others.
771 For additional information, design information can be found
772 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
774 This should only be disabled for special cases where alternate
775 atomicity implementations exist.
778 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
779 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
781 Enabling this option will allow the kernel to implement some
782 atomic operations using a software implementation of load-locked/
783 store-conditional (LLSC). On machines which do not have hardware
784 LLSC, this should be more efficient than the other alternative of
785 disabling interrupts around the atomic sequence.
