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

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

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

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