600 bool "kexec system call (EXPERIMENTAL)"
601 depends on SUPERH32 && MMU
604 kexec is a system call that implements the ability to shutdown your
605 current kernel, and to start another kernel. It is like a reboot
606 but it is independent of the system firmware. And like a reboot
607 you can start any kernel with it, not just Linux.
609 The name comes from the similarity to the exec system call.
611 It is an ongoing process to be certain the hardware in a machine
612 is properly shutdown, so do not be surprised if this code does not
613 initially work for you. As of this writing the exact hardware
614 interface is strongly in flux, so no good recommendation can be

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

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

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

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