632 kexec is a system call that implements the ability to shutdown your
633 current kernel, and to start another kernel. It is like a reboot
634 but it is independent of the system firmware. And like a reboot
635 you can start any kernel with it, not just Linux.
637 The name comes from the similarity to the exec system call.
639 It is an ongoing process to be certain the hardware in a machine
640 is properly shutdown, so do not be surprised if this code does not
641 initially work for you. As of this writing the exact hardware
642 interface is strongly in flux, so no good recommendation can be

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

667 hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
670 This gives the physical address where the kernel is loaded
671 and is ordinarily the same as MEMORY_START.
673 Different values are primarily used in the case of kexec on panic
674 where the fail safe kernel needs to run at a different address
675 than the panic-ed kernel.
678 bool "Enable seccomp to safely compute untrusted bytecode"
681 This kernel feature is useful for number crunching applications
682 that may need to compute untrusted bytecode during their
683 execution. By using pipes or other transports made available to
684 the process as file descriptors supporting the read/write
685 syscalls, it's possible to isolate those applications in
686 their own address space using seccomp. Once seccomp is
687 enabled via prctl, it cannot be disabled and the task is only
688 allowed to execute a few safe syscalls defined by each seccomp
694 bool "Symmetric multi-processing support"
695 depends on SYS_SUPPORTS_SMP
697 This enables support for systems with more than one CPU. If you have
698 a system with only one CPU, say N. If you have a system with more
701 If you say N here, the kernel will run on uni- and multiprocessor
702 machines, but will use only one CPU of a multiprocessor machine. If
703 you say Y here, the kernel will run on many, but not all,
704 uniprocessor machines. On a uniprocessor machine, the kernel
705 will run faster if you say N here.
707 People using multiprocessor machines who say Y here should also say
708 Y to "Enhanced Real Time Clock Support", below.
710 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
711 available at <http://www.tldp.org/docs.html#howto>.

722 This allows you to specify the maximum number of CPUs which this
723 kernel will support. The maximum supported value is 32 and the
724 minimum value which makes sense is 2.
726 This is purely to save memory - each supported CPU adds
727 approximately eight kilobytes to the kernel image.

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

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