ipmi
—
Intelligent Platform Management Interface driver
The ipmi
device driver supports motherboards
implementing the Intelligent Platform Management Interface version 1.5 or 2.0,
and exports sensors and the watchdog through the
envsys(4) interface.
The ipmi
driver is able to send events to
powerd(8) when a sensor's state
has changed. Intrusion sensors will send a critical event
when state is not ok. Power Supply sensors will send a
critical event when the Power Supply unit is not installed
and warning-over when the Power Supply unit is installed but
not powered on. Fan, temperature and voltage sensors will send
critical-over or critical-under when the
value is very critical, or warning-over or
warning-under if it's in a warning alert.
The ipmi
driver first appeared in
OpenBSD 3.9 and was then ported to
NetBSD 4.0.
The ipmi
driver was originally written by
Jordan Hargrave and was ported to
NetBSD by Manuel Bouyer
