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

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

722 depends on !SMP && SUPERH32
724 This enables support for gUSA (general UserSpace Atomicity).
725 This is the default implementation for both UP and non-ll/sc
726 CPUs, and is used by the libc, amongst others.
728 For additional information, design information can be found
729 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
731 This should only be disabled for special cases where alternate
732 atomicity implementations exist.
735 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
736 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
738 Enabling this option will allow the kernel to implement some
739 atomic operations using a software implementation of load-locked/
740 store-conditional (LLSC). On machines which do not have hardware
741 LLSC, this should be more efficient than the other alternative of
742 disabling interrupts around the atomic sequence.
