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

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

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

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

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