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

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

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

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

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

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