582 kexec is a system call that implements the ability to shutdown your
583 current kernel, and to start another kernel. It is like a reboot
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400584 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800585 you can start any kernel with it, not just Linux.
586
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400587 The name comes from the similarity to the exec system call.

590 is properly shutdown, so do not be surprised if this code does not
591 initially work for you. It may help to enable device hotplugging

620 This kernel feature is useful for number crunching applications
621 that may need to compute untrusted bytecode during their
622 execution. By using pipes or other transports made available to
623 the process as file descriptors supporting the read/write
624 syscalls, it's possible to isolate those applications in
625 their own address space using seccomp. Once seccomp is
626 enabled via prctl, it cannot be disabled and the task is only
627 allowed to execute a few safe syscalls defined by each seccomp
628 mode.

689 Enabling this option will allow the kernel to implement some
Matt LaPlante692105b2009-01-26 11:12:25 +0100690 atomic operations using a software implementation of load-locked/
Stuart Menefy1efe4ce2007-11-30 16:12:36 +0900691 store-conditional (LLSC). On machines which do not have hardware
692 LLSC, this should be more efficient than the other alternative of
Matt LaPlante692105b2009-01-26 11:12:25 +0100693 disabling interrupts around the atomic sequence.

696 bool "Support sparse irq numbering"
697 depends on EXPERIMENTAL
698 help
699 This enables support for sparse irqs. This is useful in general
700 as most CPUs have a fairly sparse array of IRQ vectors, which
701 the irq_desc then maps directly on to. Systems with a high
702 number of off-chip IRQs will want to treat this as
703 experimental until they have been independently verified.

747 Selecting this option will wakeup the User Break Controller (UBC) on
748 startup. Although the UBC is left in an awake state when the processor
749 comes up, some boot loaders misbehave by putting the UBC to sleep in a
750 power saving state, which causes issues with things like ptrace().
