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

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