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

679 Jump between original kernel and kexeced kernel and invoke
682 config PHYSICAL_START
683 hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
686 This gives the physical address where the kernel is loaded
687 and is ordinarily the same as MEMORY_START.
689 Different values are primarily used in the case of kexec on panic
690 where the fail safe kernel needs to run at a different address
691 than the panic-ed kernel.
694 bool "Enable seccomp to safely compute untrusted bytecode"
697 This kernel feature is useful for number crunching applications
698 that may need to compute untrusted bytecode during their
699 execution. By using pipes or other transports made available to
700 the process as file descriptors supporting the read/write
701 syscalls, it's possible to isolate those applications in
702 their own address space using seccomp. Once seccomp is
703 enabled via prctl, it cannot be disabled and the task is only
704 allowed to execute a few safe syscalls defined by each seccomp
709 config CC_STACKPROTECTOR
710 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
711 depends on SUPERH32 && EXPERIMENTAL
713 This option turns on the -fstack-protector GCC feature. This
714 feature puts, at the beginning of functions, a canary value on
715 the stack just before the return address, and validates
716 the value just before actually returning. Stack based buffer
717 overflows (that need to overwrite this return address) now also
718 overwrite the canary, which gets detected and the attack is then
719 neutralized via a kernel panic.
721 This feature requires gcc version 4.2 or above.
724 bool "Symmetric multi-processing support"
725 depends on SYS_SUPPORTS_SMP
726 select USE_GENERIC_SMP_HELPERS
728 This enables support for systems with more than one CPU. If you have
729 a system with only one CPU, like most personal computers, say N. If
730 you have a system with more than one CPU, say Y.
732 If you say N here, the kernel will run on single and multiprocessor
733 machines, but will use only one CPU of a multiprocessor machine. If
734 you say Y here, the kernel will run on many, but not all,
735 singleprocessor machines. On a singleprocessor machine, the kernel
736 will run faster if you say N here.
738 People using multiprocessor machines who say Y here should also say
739 Y to "Enhanced Real Time Clock Support", below.
741 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
742 available at <http://www.tldp.org/docs.html#howto>.
744 If you don't know what to do here, say N.
747 int "Maximum number of CPUs (2-32)"
750 default "4" if CPU_SUBTYPE_SHX3
753 This allows you to specify the maximum number of CPUs which this
754 kernel will support. The maximum supported value is 32 and the
755 minimum value which makes sense is 2.
757 This is purely to save memory - each supported CPU adds
758 approximately eight kilobytes to the kernel image.
761 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"
762 depends on SMP && HOTPLUG && EXPERIMENTAL
764 Say Y here to experiment with turning CPUs off and on. CPUs
765 can be controlled through /sys/devices/system/cpu.
767 source "kernel/Kconfig.preempt"
771 depends on !SMP && SUPERH32
773 This enables support for gUSA (general UserSpace Atomicity).
774 This is the default implementation for both UP and non-ll/sc
775 CPUs, and is used by the libc, amongst others.
777 For additional information, design information can be found
778 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
780 This should only be disabled for special cases where alternate
781 atomicity implementations exist.
784 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
785 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
787 Enabling this option will allow the kernel to implement some
788 atomic operations using a software implementation of load-locked/
789 store-conditional (LLSC). On machines which do not have hardware
790 LLSC, this should be more efficient than the other alternative of
791 disabling interrupts around the atomic sequence.

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