601 kexec is a system call that implements the ability to shutdown your
602 current kernel, and to start another kernel. It is like a reboot
603 but it is independent of the system firmware. And like a reboot
604 you can start any kernel with it, not just Linux.
606 The name comes from the similarity to the exec system call.
608 It is an ongoing process to be certain the hardware in a machine
609 is properly shutdown, so do not be surprised if this code does not
610 initially work for you. As of this writing the exact hardware
611 interface is strongly in flux, so no good recommendation can be

619 This should be normally only set in special crash dump kernels
620 which are loaded in the main kernel with kexec-tools into
621 a specially reserved region and then later executed after
622 a crash by kdump/kexec. The crash dump kernel must be compiled
623 to a memory address not used by the main kernel using

636 hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
639 This gives the physical address where the kernel is loaded
640 and is ordinarily the same as MEMORY_START.
642 Different values are primarily used in the case of kexec on panic
643 where the fail safe kernel needs to run at a different address
644 than the panic-ed kernel.
647 bool "Enable seccomp to safely compute untrusted bytecode"
650 This kernel feature is useful for number crunching applications
651 that may need to compute untrusted bytecode during their
652 execution. By using pipes or other transports made available to
653 the process as file descriptors supporting the read/write
654 syscalls, it's possible to isolate those applications in
655 their own address space using seccomp. Once seccomp is
656 enabled via prctl, it cannot be disabled and the task is only
657 allowed to execute a few safe syscalls defined by each seccomp
663 bool "Symmetric multi-processing support"
664 depends on SYS_SUPPORTS_SMP
666 This enables support for systems with more than one CPU. If you have
667 a system with only one CPU, say N. If you have a system with more
670 If you say N here, the kernel will run on uni- and multiprocessor
671 machines, but will use only one CPU of a multiprocessor machine. If
672 you say Y here, the kernel will run on many, but not all,
673 uniprocessor machines. On a uniprocessor machine, the kernel
674 will run faster if you say N here.
676 People using multiprocessor machines who say Y here should also say
677 Y to "Enhanced Real Time Clock Support", below.
679 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
680 available at <http://www.tldp.org/docs.html#howto>.
682 If you don't know what to do here, say N.
685 int "Maximum number of CPUs (2-32)"
688 default "4" if CPU_SUBTYPE_SHX3
691 This allows you to specify the maximum number of CPUs which this
692 kernel will support. The maximum supported value is 32 and the
693 minimum value which makes sense is 2.
695 This is purely to save memory - each supported CPU adds
696 approximately eight kilobytes to the kernel image.
699 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"

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

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