613 bool "kexec system call (EXPERIMENTAL)"
614 depends on SUPERH32 && EXPERIMENTAL && MMU
616 kexec is a system call that implements the ability to shutdown your
617 current kernel, and to start another kernel. It is like a reboot
618 but it is independent of the system firmware. And like a reboot
619 you can start any kernel with it, not just Linux.
621 The name comes from the similarity to the exec system call.
623 It is an ongoing process to be certain the hardware in a machine
624 is properly shutdown, so do not be surprised if this code does not
625 initially work for you. It may help to enable device hotplugging
626 support. As of this writing the exact hardware interface is
627 strongly in flux, so no good recommendation can be made.
630 bool "kernel crash dumps (EXPERIMENTAL)"
631 depends on SUPERH32 && EXPERIMENTAL && BROKEN_ON_SMP
633 Generate crash dump after being started by kexec.
634 This should be normally only set in special crash dump kernels
635 which are loaded in the main kernel with kexec-tools into
636 a specially reserved region and then later executed after
637 a crash by kdump/kexec. The crash dump kernel must be compiled
638 to a memory address not used by the main kernel using
641 For more details see Documentation/kdump/kdump.txt

647 Jump between original kernel and kexeced kernel and invoke
650 config PHYSICAL_START
651 hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
654 This gives the physical address where the kernel is loaded
655 and is ordinarily the same as MEMORY_START.
657 Different values are primarily used in the case of kexec on panic
658 where the fail safe kernel needs to run at a different address
659 than the panic-ed kernel.
662 bool "Enable seccomp to safely compute untrusted bytecode"
665 This kernel feature is useful for number crunching applications
666 that may need to compute untrusted bytecode during their
667 execution. By using pipes or other transports made available to
668 the process as file descriptors supporting the read/write
669 syscalls, it's possible to isolate those applications in
670 their own address space using seccomp. Once seccomp is
671 enabled via prctl, it cannot be disabled and the task is only
672 allowed to execute a few safe syscalls defined by each seccomp
678 bool "Symmetric multi-processing support"
679 depends on SYS_SUPPORTS_SMP
680 select USE_GENERIC_SMP_HELPERS
682 This enables support for systems with more than one CPU. If you have
683 a system with only one CPU, like most personal computers, say N. If
684 you have a system with more than one CPU, say Y.
686 If you say N here, the kernel will run on single and multiprocessor
687 machines, but will use only one CPU of a multiprocessor machine. If
688 you say Y here, the kernel will run on many, but not all,
689 singleprocessor machines. On a singleprocessor machine, the kernel
690 will run faster if you say N here.
692 People using multiprocessor machines who say Y here should also say
693 Y to "Enhanced Real Time Clock Support", below.
695 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
696 available at <http://www.tldp.org/docs.html#howto>.
698 If you don't know what to do here, say N.
701 int "Maximum number of CPUs (2-32)"
704 default "4" if CPU_SUBTYPE_SHX3
707 This allows you to specify the maximum number of CPUs which this
708 kernel will support. The maximum supported value is 32 and the
709 minimum value which makes sense is 2.
711 This is purely to save memory - each supported CPU adds
712 approximately eight kilobytes to the kernel image.
715 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"
716 depends on SMP && HOTPLUG && EXPERIMENTAL
718 Say Y here to experiment with turning CPUs off and on. CPUs
719 can be controlled through /sys/devices/system/cpu.
721 source "kernel/Kconfig.preempt"
725 depends on !SMP && SUPERH32
727 This enables support for gUSA (general UserSpace Atomicity).
728 This is the default implementation for both UP and non-ll/sc
729 CPUs, and is used by the libc, amongst others.
731 For additional information, design information can be found
732 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
734 This should only be disabled for special cases where alternate
735 atomicity implementations exist.
738 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
739 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
741 Enabling this option will allow the kernel to implement some
742 atomic operations using a software implementation of load-locked/
743 store-conditional (LLSC). On machines which do not have hardware
744 LLSC, this should be more efficient than the other alternative of
745 disabling interrupts around the atomic sequence.
