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

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