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

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