256 of the specific ones mentioned above, which means you need to enter
257 all sorts of stuff like CONFIG_MEMORY_START because the config
258 system doesn't already know what it is. You get a machine vector

448 Select this option if you want to disable continuous timer ticks
449 and have them programmed to occur as required. This option saves
450 power as the system can remain in idle state for longer.
451
452 By default dynamic tick is disabled during the boot, and can be
453 manually enabled with:
454
455 echo 1 > /sys/devices/system/timer/timer0/dyn_tick

457 Alternatively, if you want dynamic tick automatically enabled
458 during boot, pass "dyntick=enable" via the kernel command string.

533 kexec is a system call that implements the ability to shutdown your

Matt LaPlante1f1332f2006-06-29 01:32:47 -0400535 but it is independent of the system firmware. And like a reboot
Paul Mundtcad82442006-01-16 22:14:19 -0800536 you can start any kernel with it, not just Linux.
537
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400538 The name comes from the similarity to the exec system call.
Paul Mundtcad82442006-01-16 22:14:19 -0800539
540 It is an ongoing process to be certain the hardware in a machine
541 is properly shutdown, so do not be surprised if this code does not
542 initially work for you. It may help to enable device hotplugging
543 support. As of this writing the exact hardware interface is
544 strongly in flux, so no good recommendation can be made.
