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

623 depends on SUPERH32 && BROKEN_ON_SMP
625 Generate crash dump after being started by kexec.
626 This should be normally only set in special crash dump kernels
627 which are loaded in the main kernel with kexec-tools into
628 a specially reserved region and then later executed after
629 a crash by kdump/kexec. The crash dump kernel must be compiled
630 to a memory address not used by the main kernel using

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

695 default "4" if CPU_SUBTYPE_SHX3
698 This allows you to specify the maximum number of CPUs which this
699 kernel will support. The maximum supported value is 32 and the
700 minimum value which makes sense is 2.
702 This is purely to save memory - each supported CPU adds
703 approximately eight kilobytes to the kernel image.
706 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"

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

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