601 bool "kexec system call (EXPERIMENTAL)"
602 depends on SUPERH32 && MMU
605 kexec is a system call that implements the ability to shutdown your
606 current kernel, and to start another kernel. It is like a reboot
607 but it is independent of the system firmware. And like a reboot
608 you can start any kernel with it, not just Linux.
610 The name comes from the similarity to the exec system call.
612 It is an ongoing process to be certain the hardware in a machine
613 is properly shutdown, so do not be surprised if this code does not
614 initially work for you. As of this writing the exact hardware
615 interface is strongly in flux, so no good recommendation can be
619 bool "kernel crash dumps (EXPERIMENTAL)"
620 depends on SUPERH32 && BROKEN_ON_SMP
622 Generate crash dump after being started by kexec.
623 This should be normally only set in special crash dump kernels
624 which are loaded in the main kernel with kexec-tools into
625 a specially reserved region and then later executed after
626 a crash by kdump/kexec. The crash dump kernel must be compiled
627 to a memory address not used by the main kernel using

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

713 depends on !SMP && SUPERH32
715 This enables support for gUSA (general UserSpace Atomicity).
716 This is the default implementation for both UP and non-ll/sc
717 CPUs, and is used by the libc, amongst others.
719 For additional information, design information can be found
720 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
722 This should only be disabled for special cases where alternate
723 atomicity implementations exist.
726 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
727 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
729 Enabling this option will allow the kernel to implement some
730 atomic operations using a software implementation of load-locked/
731 store-conditional (LLSC). On machines which do not have hardware
732 LLSC, this should be more efficient than the other alternative of
733 disabling interrupts around the atomic sequence.
