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

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

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

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

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