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.

674 you have a system with more than one CPU, say Y.
