617 kexec is a system call that implements the ability to shutdown your
618 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400619 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800620 you can start any kernel with it, not just Linux.
621
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400622 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800623
624 It is an ongoing process to be certain the hardware in a machine
625 is properly shutdown, so do not be surprised if this code does not
626 initially work for you. It may help to enable device hotplugging
627 support. As of this writing the exact hardware interface is
628 strongly in flux, so no good recommendation can be made.

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

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

697 This allows you to specify the maximum number of CPUs which this
698 kernel will support. The maximum supported value is 32 and the
699 minimum value which makes sense is 2.

701 This is purely to save memory - each supported CPU adds
702 approximately eight kilobytes to the kernel image.

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

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

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