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

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

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

806 Find out whether you have ISA slots on your motherboard. ISA is the
807 name of a bus system, i.e. the way the CPU talks to the other stuff
808 inside your box. Other bus systems are PCI, EISA, MicroChannel
809 (MCA) or VESA. ISA is an older system, now being displaced by PCI;
810 newer boards don't support it. If you have ISA, say Y, otherwise N.
815 The Extended Industry Standard Architecture (EISA) bus was
816 developed as an open alternative to the IBM MicroChannel bus.
818 The EISA bus provided some of the features of the IBM MicroChannel
819 bus while maintaining backward compatibility with cards made for
820 the older ISA bus. The EISA bus saw limited use between 1988 and
821 1995 when it was made obsolete by the PCI bus.
823 Say Y here if you are building a kernel for an EISA-based machine.
830 MicroChannel Architecture is found in some IBM PS/2 machines and
831 laptops. It is a bus system similar to PCI or ISA. See
832 <file:Documentation/mca.txt> (and especially the web page given
833 there) before attempting to build an MCA bus kernel.
