622 kexec is a system call that implements the ability to shutdown your
623 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400624 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800625 you can start any kernel with it, not just Linux.
626
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400627 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800628
629 It is an ongoing process to be certain the hardware in a machine
630 is properly shutdown, so do not be surprised if this code does not
631 initially work for you. It may help to enable device hotplugging
632 support. As of this writing the exact hardware interface is
633 strongly in flux, so no good recommendation can be made.

660 This kernel feature is useful for number crunching applications
661 that may need to compute untrusted bytecode during their
662 execution. By using pipes or other transports made available to
663 the process as file descriptors supporting the read/write
664 syscalls, it's possible to isolate those applications in
665 their own address space using seccomp. Once seccomp is
666 enabled via prctl, it cannot be disabled and the task is only
667 allowed to execute a few safe syscalls defined by each seccomp
668 mode.

677 This enables support for systems with more than one CPU. If you have
678 a system with only one CPU, like most personal computers, say N. If
679 you have a system with more than one CPU, say Y.
680
681 If you say N here, the kernel will run on single and multiprocessor
682 machines, but will use only one CPU of a multiprocessor machine. If
683 you say Y here, the kernel will run on many, but not all,
684 singleprocessor machines. On a singleprocessor machine, the kernel
685 will run faster if you say N here.
686
687 People using multiprocessor machines who say Y here should also say
688 Y to "Enhanced Real Time Clock Support", below.

702 This allows you to specify the maximum number of CPUs which this
703 kernel will support. The maximum supported value is 32 and the
704 minimum value which makes sense is 2.
705
706 This is purely to save memory - each supported CPU adds
707 approximately eight kilobytes to the kernel image.

716 This is the default implementation for both UP and non-ll/sc
717 CPUs, and is used by the libc, amongst others.

720 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
