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

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