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

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