608 kexec is a system call that implements the ability to shutdown your
609 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400610 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800611 you can start any kernel with it, not just Linux.
612
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400613 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800614
615 It is an ongoing process to be certain the hardware in a machine
616 is properly shutdown, so do not be surprised if this code does not
617 initially work for you. It may help to enable device hotplugging
618 support. As of this writing the exact hardware interface is
619 strongly in flux, so no good recommendation can be made.

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

668 machines, but will use only one CPU of a multiprocessor machine. If
669 you say Y here, the kernel will run on many, but not all,
670 singleprocessor machines. On a singleprocessor machine, the kernel
671 will run faster if you say N here.

673 People using multiprocessor machines who say Y here should also say
674 Y to "Enhanced Real Time Clock Support", below.
