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

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