599 kexec is a system call that implements the ability to shutdown your
600 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400601 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800602 you can start any kernel with it, not just Linux.
603
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400604 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800605
606 It is an ongoing process to be certain the hardware in a machine
607 is properly shutdown, so do not be surprised if this code does not
608 initially work for you. It may help to enable device hotplugging
609 support. As of this writing the exact hardware interface is
610 strongly in flux, so no good recommendation can be made.

637 This kernel feature is useful for number crunching applications
638 that may need to compute untrusted bytecode during their
639 execution. By using pipes or other transports made available to
640 the process as file descriptors supporting the read/write
641 syscalls, it's possible to isolate those applications in
642 their own address space using seccomp. Once seccomp is
643 enabled via prctl, it cannot be disabled and the task is only
644 allowed to execute a few safe syscalls defined by each seccomp
645 mode.

679 This allows you to specify the maximum number of CPUs which this
680 kernel will support. The maximum supported value is 32 and the
681 minimum value which makes sense is 2.
682
683 This is purely to save memory - each supported CPU adds
684 approximately eight kilobytes to the kernel image.

692 This enables support for gUSA (general UserSpace Atomicity).
693 This is the default implementation for both UP and non-ll/sc
694 CPUs, and is used by the libc, amongst others.

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

716 This enables support for sparse irqs. This is useful in general
717 as most CPUs have a fairly sparse array of IRQ vectors, which
718 the irq_desc then maps directly on to. Systems with a high
719 number of off-chip IRQs will want to treat this as
720 experimental until they have been independently verified.
