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

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

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

792 Find out whether you have ISA slots on your motherboard. ISA is the
793 name of a bus system, i.e. the way the CPU talks to the other stuff
794 inside your box. Other bus systems are PCI, EISA, MicroChannel
795 (MCA) or VESA. ISA is an older system, now being displaced by PCI;
796 newer boards don't support it. If you have ISA, say Y, otherwise N.
801 The Extended Industry Standard Architecture (EISA) bus was
802 developed as an open alternative to the IBM MicroChannel bus.
804 The EISA bus provided some of the features of the IBM MicroChannel
805 bus while maintaining backward compatibility with cards made for
806 the older ISA bus. The EISA bus saw limited use between 1988 and
807 1995 when it was made obsolete by the PCI bus.
809 Say Y here if you are building a kernel for an EISA-based machine.
816 MicroChannel Architecture is found in some IBM PS/2 machines and
817 laptops. It is a bus system similar to PCI or ISA. See
818 <file:Documentation/mca.txt> (and especially the web page given
819 there) before attempting to build an MCA bus kernel.
