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

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

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