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

677 Jump between original kernel and kexeced kernel and invoke
680 config PHYSICAL_START
681 hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
684 This gives the physical address where the kernel is loaded
685 and is ordinarily the same as MEMORY_START.
687 Different values are primarily used in the case of kexec on panic
688 where the fail safe kernel needs to run at a different address
689 than the panic-ed kernel.
692 bool "Enable seccomp to safely compute untrusted bytecode"
695 This kernel feature is useful for number crunching applications
696 that may need to compute untrusted bytecode during their
697 execution. By using pipes or other transports made available to
698 the process as file descriptors supporting the read/write
699 syscalls, it's possible to isolate those applications in
700 their own address space using seccomp. Once seccomp is
701 enabled via prctl, it cannot be disabled and the task is only
702 allowed to execute a few safe syscalls defined by each seccomp
707 config CC_STACKPROTECTOR
708 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
709 depends on SUPERH32 && EXPERIMENTAL
711 This option turns on the -fstack-protector GCC feature. This
712 feature puts, at the beginning of functions, a canary value on
713 the stack just before the return address, and validates
714 the value just before actually returning. Stack based buffer
715 overflows (that need to overwrite this return address) now also
716 overwrite the canary, which gets detected and the attack is then
717 neutralized via a kernel panic.
719 This feature requires gcc version 4.2 or above.
722 bool "Symmetric multi-processing support"
723 depends on SYS_SUPPORTS_SMP
724 select USE_GENERIC_SMP_HELPERS
726 This enables support for systems with more than one CPU. If you have
727 a system with only one CPU, like most personal computers, say N. If
728 you have a system with more than one CPU, say Y.
730 If you say N here, the kernel will run on single and multiprocessor
731 machines, but will use only one CPU of a multiprocessor machine. If
732 you say Y here, the kernel will run on many, but not all,
733 singleprocessor machines. On a singleprocessor machine, the kernel
734 will run faster if you say N here.
736 People using multiprocessor machines who say Y here should also say
737 Y to "Enhanced Real Time Clock Support", below.
739 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
740 available at <http://www.tldp.org/docs.html#howto>.
742 If you don't know what to do here, say N.
745 int "Maximum number of CPUs (2-32)"
748 default "4" if CPU_SUBTYPE_SHX3
751 This allows you to specify the maximum number of CPUs which this
752 kernel will support. The maximum supported value is 32 and the
753 minimum value which makes sense is 2.
755 This is purely to save memory - each supported CPU adds
756 approximately eight kilobytes to the kernel image.
759 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"
760 depends on SMP && HOTPLUG && EXPERIMENTAL
762 Say Y here to experiment with turning CPUs off and on. CPUs
763 can be controlled through /sys/devices/system/cpu.
765 source "kernel/Kconfig.preempt"

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

843 kernel image to an MMC card and boot the kernel straight from
