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
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400625 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800626 you can start any kernel with it, not just Linux.
627
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400628 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800629
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.

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

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

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

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