615 kexec is a system call that implements the ability to shutdown your
616 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400617 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800618 you can start any kernel with it, not just Linux.
619
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400620 The name comes from the similarity to the exec system call.

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

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

734 the irq_desc then maps directly on to. Systems with a high

736 experimental until they have been independently verified.
