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

662 bool "Enable seccomp to safely compute untrusted bytecode"
665 This kernel feature is useful for number crunching applications
666 that may need to compute untrusted bytecode during their
667 execution. By using pipes or other transports made available to
668 the process as file descriptors supporting the read/write
669 syscalls, it's possible to isolate those applications in
670 their own address space using seccomp. Once seccomp is
671 enabled via prctl, it cannot be disabled and the task is only
672 allowed to execute a few safe syscalls defined by each seccomp
678 bool "Symmetric multi-processing support"
679 depends on SYS_SUPPORTS_SMP
680 select USE_GENERIC_SMP_HELPERS
682 This enables support for systems with more than one CPU. If you have
683 a system with only one CPU, like most personal computers, say N. If
684 you have a system with more than one CPU, say Y.
686 If you say N here, the kernel will run on single and multiprocessor
687 machines, but will use only one CPU of a multiprocessor machine. If
688 you say Y here, the kernel will run on many, but not all,
689 singleprocessor machines. On a singleprocessor machine, the kernel
690 will run faster if you say N here.
692 People using multiprocessor machines who say Y here should also say
693 Y to "Enhanced Real Time Clock Support", below.
695 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
696 available at <http://www.tldp.org/docs.html#howto>.
698 If you don't know what to do here, say N.
701 int "Maximum number of CPUs (2-32)"

707 This allows you to specify the maximum number of CPUs which this
708 kernel will support. The maximum supported value is 32 and the
709 minimum value which makes sense is 2.
711 This is purely to save memory - each supported CPU adds
712 approximately eight kilobytes to the kernel image.
715 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"

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

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