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

652 bool "Symmetric multi-processing support"
653 depends on SYS_SUPPORTS_SMP
655 This enables support for systems with more than one CPU. If you have
656 a system with only one CPU, like most personal computers, say N. If
657 you have a system with more than one CPU, say Y.
659 If you say N here, the kernel will run on single and multiprocessor
660 machines, but will use only one CPU of a multiprocessor machine. If
661 you say Y here, the kernel will run on many, but not all,
662 singleprocessor machines. On a singleprocessor machine, the kernel
663 will run faster if you say N here.
665 People using multiprocessor machines who say Y here should also say
666 Y to "Enhanced Real Time Clock Support", below.
668 See also the <file:Documentation/smp.txt>,
669 <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available
670 at <http://www.tldp.org/docs.html#howto>.
672 If you don't know what to do here, say N.
675 int "Maximum number of CPUs (2-32)"
678 default "4" if CPU_SHX3
681 This allows you to specify the maximum number of CPUs which this
682 kernel will support. The maximum supported value is 32 and the
683 minimum value which makes sense is 2.
685 This is purely to save memory - each supported CPU adds
686 approximately eight kilobytes to the kernel image.
688 source "kernel/Kconfig.preempt"
694 This enables support for gUSA (general UserSpace Atomicity).
695 This is the default implementation for both UP and non-ll/sc
696 CPUs, and is used by the libc, amongst others.
698 For additional information, design information can be found
699 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.

759 Find out whether you have ISA slots on your motherboard. ISA is the
760 name of a bus system, i.e. the way the CPU talks to the other stuff
761 inside your box. Other bus systems are PCI, EISA, MicroChannel
762 (MCA) or VESA. ISA is an older system, now being displaced by PCI;
763 newer boards don't support it. If you have ISA, say Y, otherwise N.
768 The Extended Industry Standard Architecture (EISA) bus was
769 developed as an open alternative to the IBM MicroChannel bus.
771 The EISA bus provided some of the features of the IBM MicroChannel
772 bus while maintaining backward compatibility with cards made for
773 the older ISA bus. The EISA bus saw limited use between 1988 and
774 1995 when it was made obsolete by the PCI bus.
776 Say Y here if you are building a kernel for an EISA-based machine.
783 MicroChannel Architecture is found in some IBM PS/2 machines and
784 laptops. It is a bus system similar to PCI or ISA. See
785 <file:Documentation/mca.txt> (and especially the web page given
786 there) before attempting to build an MCA bus kernel.
