POWER(4)             OpenBSD Programmer's Manual (SPARC64)            POWER(4)

NAME
     power - power button

SYNOPSIS
     power* at ebus?

DESCRIPTION
     Some UltraSPARC host bridges provide an interrupt when the power button
     is depressed.  The power driver catches that interrupt.  If the
     machdep.kbdreset sysctl(8) is set to 1, power will signal init(8) to do a
     clean shutdown.

SEE ALSO
     ebus(4), intro(4), init(8), rc.shutdown(8), sysctl(8)

HISTORY
     The power driver was first supported in OpenBSD 4.0.

AUTHORS
     The driver was written by Jason Wright <jason@thought.net>.
