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

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