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

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

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

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