power — power
button
power0 at macebus0 (O2)
power0 at mainbus0 (Octane)
The SGI O2 and Octane machines generate an interrupt when the
power button on the front panel is pressed. The
power driver catches that interrupt. If the
hw.allowpowerdown
sysctl(8) is set to 1,
power will then signal
init(8) to do a clean
shutdown(8).
Support for the power driver first
appeared in OpenBSD 4.3.
The power driver was written by
