616 kexec is a system call that implements the ability to shutdown your
617 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400618 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800619 you can start any kernel with it, not just Linux.
620
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400621 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800622
623 It is an ongoing process to be certain the hardware in a machine
624 is properly shutdown, so do not be surprised if this code does not
625 initially work for you. It may help to enable device hotplugging
626 support. As of this writing the exact hardware interface is
627 strongly in flux, so no good recommendation can be made.

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

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