653 bool "kexec system call (EXPERIMENTAL)"
654 depends on EXPERIMENTAL
656 kexec is a system call that implements the ability to shutdown your
657 current kernel, and to start another kernel. It is like a reboot
658 but it is independent of the system firmware. And like a reboot
659 you can start any kernel with it, not just Linux.
661 The name comes from the similarity to the exec system call.
663 It is an ongoing process to be certain the hardware in a machine
664 is properly shutdown, so do not be surprised if this code does not
665 initially work for you. It may help to enable device hotplugging
666 support. As of this writing the exact hardware interface is
667 strongly in flux, so no good recommendation can be made.
670 bool "kernel crash dumps (EXPERIMENTAL)"
671 depends on EXPERIMENTAL
673 Generate crash dump after being started by kexec.
674 This should be normally only set in special crash dump kernels
675 which are loaded in the main kernel with kexec-tools into
676 a specially reserved region and then later executed after
677 a crash by kdump/kexec. The crash dump kernel must be compiled
678 to a memory address not used by the main kernel using

684 bool "Symmetric multi-processing support"
685 depends on SYS_SUPPORTS_SMP
687 This enables support for systems with more than one CPU. If you have
688 a system with only one CPU, like most personal computers, say N. If
689 you have a system with more than one CPU, say Y.
691 If you say N here, the kernel will run on single and multiprocessor
692 machines, but will use only one CPU of a multiprocessor machine. If
693 you say Y here, the kernel will run on many, but not all,
694 singleprocessor machines. On a singleprocessor machine, the kernel
695 will run faster if you say N here.
697 People using multiprocessor machines who say Y here should also say
698 Y to "Enhanced Real Time Clock Support", below.
700 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
701 available at <http://www.tldp.org/docs.html#howto>.
703 If you don't know what to do here, say N.
706 int "Maximum number of CPUs (2-32)"
709 default "4" if CPU_SHX3
712 This allows you to specify the maximum number of CPUs which this
713 kernel will support. The maximum supported value is 32 and the
714 minimum value which makes sense is 2.
716 This is purely to save memory - each supported CPU adds
717 approximately eight kilobytes to the kernel image.
719 source "kernel/Kconfig.preempt"
723 depends on !SMP && SUPERH32
725 This enables support for gUSA (general UserSpace Atomicity).
726 This is the default implementation for both UP and non-ll/sc
727 CPUs, and is used by the libc, amongst others.
729 For additional information, design information can be found
730 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
732 This should only be disabled for special cases where alternate
733 atomicity implementations exist.
736 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
737 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
739 Enabling this option will allow the kernel to implement some
740 atomic operations using a software implemention of load-locked/
741 store-conditional (LLSC). On machines which do not have hardware
742 LLSC, this should be more efficient than the other alternative of
743 disabling insterrupts around the atomic sequence.

772 comes up, some boot loaders misbehave by putting the UBC to sleep in a

800 Find out whether you have ISA slots on your motherboard. ISA is the
801 name of a bus system, i.e. the way the CPU talks to the other stuff
802 inside your box. Other bus systems are PCI, EISA, MicroChannel
803 (MCA) or VESA. ISA is an older system, now being displaced by PCI;
804 newer boards don't support it. If you have ISA, say Y, otherwise N.
809 The Extended Industry Standard Architecture (EISA) bus was
810 developed as an open alternative to the IBM MicroChannel bus.
812 The EISA bus provided some of the features of the IBM MicroChannel
813 bus while maintaining backward compatibility with cards made for
814 the older ISA bus. The EISA bus saw limited use between 1988 and
815 1995 when it was made obsolete by the PCI bus.
817 Say Y here if you are building a kernel for an EISA-based machine.
824 MicroChannel Architecture is found in some IBM PS/2 machines and
825 laptops. It is a bus system similar to PCI or ISA. See
826 <file:Documentation/mca.txt> (and especially the web page given
827 there) before attempting to build an MCA bus kernel.
