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

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

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

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

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