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

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

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