618 kexec is a system call that implements the ability to shutdown your
619 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400620 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800621 you can start any kernel with it, not just Linux.
622
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400623 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800624
625 It is an ongoing process to be certain the hardware in a machine
626 is properly shutdown, so do not be surprised if this code does not
627 initially work for you. It may help to enable device hotplugging
628 support. As of this writing the exact hardware interface is
629 strongly in flux, so no good recommendation can be made.

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

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

698 This allows you to specify the maximum number of CPUs which this
699 kernel will support. The maximum supported value is 32 and the
700 minimum value which makes sense is 2.
701
702 This is purely to save memory - each supported CPU adds
703 approximately eight kilobytes to the kernel image.

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

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

728 LLSC, this should be more efficient than the other alternative of

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