621 kexec is a system call that implements the ability to shutdown your
622 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400623 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800624 you can start any kernel with it, not just Linux.
625
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400626 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800627
628 It is an ongoing process to be certain the hardware in a machine
629 is properly shutdown, so do not be surprised if this code does not
630 initially work for you. It may help to enable device hotplugging
631 support. As of this writing the exact hardware interface is
632 strongly in flux, so no good recommendation can be made.

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

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

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

725 For additional information, design information can be found
726 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
