614 bool "kexec system call (EXPERIMENTAL)"
615 depends on SUPERH32 && EXPERIMENTAL && MMU
617 kexec is a system call that implements the ability to shutdown your
618 current kernel, and to start another kernel. It is like a reboot
619 but it is independent of the system firmware. And like a reboot
620 you can start any kernel with it, not just Linux.
622 The name comes from the similarity to the exec system call.
624 It is an ongoing process to be certain the hardware in a machine
625 is properly shutdown, so do not be surprised if this code does not
626 initially work for you. It may help to enable device hotplugging
627 support. As of this writing the exact hardware interface is
628 strongly in flux, so no good recommendation can be made.
631 bool "kernel crash dumps (EXPERIMENTAL)"
632 depends on SUPERH32 && EXPERIMENTAL && BROKEN_ON_SMP
634 Generate crash dump after being started by kexec.
635 This should be normally only set in special crash dump kernels
636 which are loaded in the main kernel with kexec-tools into
637 a specially reserved region and then later executed after
638 a crash by kdump/kexec. The crash dump kernel must be compiled
639 to a memory address not used by the main kernel using

652 bool "Enable seccomp to safely compute untrusted bytecode"
655 This kernel feature is useful for number crunching applications
656 that may need to compute untrusted bytecode during their
657 execution. By using pipes or other transports made available to
658 the process as file descriptors supporting the read/write
659 syscalls, it's possible to isolate those applications in
660 their own address space using seccomp. Once seccomp is
661 enabled via prctl, it cannot be disabled and the task is only
662 allowed to execute a few safe syscalls defined by each seccomp
668 bool "Symmetric multi-processing support"
669 depends on SYS_SUPPORTS_SMP
670 select USE_GENERIC_SMP_HELPERS
672 This enables support for systems with more than one CPU. If you have
673 a system with only one CPU, like most personal computers, say N. If
674 you have a system with more than one CPU, say Y.
676 If you say N here, the kernel will run on single and multiprocessor
677 machines, but will use only one CPU of a multiprocessor machine. If
678 you say Y here, the kernel will run on many, but not all,
679 singleprocessor machines. On a singleprocessor machine, the kernel
680 will run faster if you say N here.
682 People using multiprocessor machines who say Y here should also say
683 Y to "Enhanced Real Time Clock Support", below.
685 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
686 available at <http://www.tldp.org/docs.html#howto>.
688 If you don't know what to do here, say N.
691 int "Maximum number of CPUs (2-32)"
694 default "4" if CPU_SUBTYPE_SHX3
697 This allows you to specify the maximum number of CPUs which this
698 kernel will support. The maximum supported value is 32 and the
699 minimum value which makes sense is 2.
701 This is purely to save memory - each supported CPU adds
702 approximately eight kilobytes to the kernel image.
705 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"
706 depends on SMP && HOTPLUG && EXPERIMENTAL
708 Say Y here to experiment with turning CPUs off and on. CPUs
709 can be controlled through /sys/devices/system/cpu.
711 source "kernel/Kconfig.preempt"
715 depends on !SMP && SUPERH32
717 This enables support for gUSA (general UserSpace Atomicity).
718 This is the default implementation for both UP and non-ll/sc
719 CPUs, and is used by the libc, amongst others.
721 For additional information, design information can be found
722 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
724 This should only be disabled for special cases where alternate
725 atomicity implementations exist.
728 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
729 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
731 Enabling this option will allow the kernel to implement some
732 atomic operations using a software implementation of load-locked/
733 store-conditional (LLSC). On machines which do not have hardware
734 LLSC, this should be more efficient than the other alternative of
735 disabling interrupts around the atomic sequence.
