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

658 bool "Enable seccomp to safely compute untrusted bytecode"
661 This kernel feature is useful for number crunching applications
662 that may need to compute untrusted bytecode during their
663 execution. By using pipes or other transports made available to
664 the process as file descriptors supporting the read/write
665 syscalls, it's possible to isolate those applications in
666 their own address space using seccomp. Once seccomp is
667 enabled via prctl, it cannot be disabled and the task is only
668 allowed to execute a few safe syscalls defined by each seccomp
674 bool "Symmetric multi-processing support"
675 depends on SYS_SUPPORTS_SMP
676 select USE_GENERIC_SMP_HELPERS
678 This enables support for systems with more than one CPU. If you have
679 a system with only one CPU, like most personal computers, say N. If
680 you have a system with more than one CPU, say Y.
682 If you say N here, the kernel will run on single and multiprocessor
683 machines, but will use only one CPU of a multiprocessor machine. If
684 you say Y here, the kernel will run on many, but not all,
685 singleprocessor machines. On a singleprocessor machine, the kernel
686 will run faster if you say N here.
688 People using multiprocessor machines who say Y here should also say
689 Y to "Enhanced Real Time Clock Support", below.
691 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
692 available at <http://www.tldp.org/docs.html#howto>.
694 If you don't know what to do here, say N.
697 int "Maximum number of CPUs (2-32)"
700 default "4" if CPU_SUBTYPE_SHX3
703 This allows you to specify the maximum number of CPUs which this
704 kernel will support. The maximum supported value is 32 and the
705 minimum value which makes sense is 2.
707 This is purely to save memory - each supported CPU adds
708 approximately eight kilobytes to the kernel image.
711 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"

715 can be controlled through /sys/devices/system/cpu.

723 This enables support for gUSA (general UserSpace Atomicity).
724 This is the default implementation for both UP and non-ll/sc
725 CPUs, and is used by the libc, amongst others.
727 For additional information, design information can be found
728 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
730 This should only be disabled for special cases where alternate
731 atomicity implementations exist.
734 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
735 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
737 Enabling this option will allow the kernel to implement some
738 atomic operations using a software implementation of load-locked/
739 store-conditional (LLSC). On machines which do not have hardware
740 LLSC, this should be more efficient than the other alternative of
741 disabling interrupts around the atomic sequence.
