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

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

634 hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
637 This gives the physical address where the kernel is loaded
638 and is ordinarily the same as MEMORY_START.
640 Different values are primarily used in the case of kexec on panic
641 where the fail safe kernel needs to run at a different address
642 than the panic-ed kernel.
645 bool "Enable seccomp to safely compute untrusted bytecode"
648 This kernel feature is useful for number crunching applications
649 that may need to compute untrusted bytecode during their
650 execution. By using pipes or other transports made available to
651 the process as file descriptors supporting the read/write
652 syscalls, it's possible to isolate those applications in
653 their own address space using seccomp. Once seccomp is
654 enabled via prctl, it cannot be disabled and the task is only
655 allowed to execute a few safe syscalls defined by each seccomp
661 bool "Symmetric multi-processing support"
662 depends on SYS_SUPPORTS_SMP
664 This enables support for systems with more than one CPU. If you have
665 a system with only one CPU, say N. If you have a system with more
668 If you say N here, the kernel will run on uni- and multiprocessor
669 machines, but will use only one CPU of a multiprocessor machine. If
670 you say Y here, the kernel will run on many, but not all,
671 uniprocessor machines. On a uniprocessor machine, the kernel
672 will run faster if you say N here.
674 People using multiprocessor machines who say Y here should also say
675 Y to "Enhanced Real Time Clock Support", below.
677 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
678 available at <http://www.tldp.org/docs.html#howto>.
680 If you don't know what to do here, say N.

686 default "4" if CPU_SUBTYPE_SHX3
689 This allows you to specify the maximum number of CPUs which this
690 kernel will support. The maximum supported value is 32 and the
691 minimum value which makes sense is 2.
693 This is purely to save memory - each supported CPU adds
694 approximately eight kilobytes to the kernel image.

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

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