614 kexec is a system call that implements the ability to shutdown your
615 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400616 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800617 you can start any kernel with it, not just Linux.
618
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400619 The name comes from the similarity to the exec system call.

621 It is an ongoing process to be certain the hardware in a machine
622 is properly shutdown, so do not be surprised if this code does not
623 initially work for you. It may help to enable device hotplugging
624 support. As of this writing the exact hardware interface is
625 strongly in flux, so no good recommendation can be made.

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

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

695 kernel will support. The maximum supported value is 32 and the
696 minimum value which makes sense is 2.

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