.Nd Intelligent Platform Management Interface driver
.Sh SYNOPSIS
.Cd "ipmi0 at mainbus?"
.Sh DESCRIPTION
The
.Nm
2006-10-03 06:11:19 +04:00
device driver supports motherboards implementing the
2006-10-01 22:43:11 +04:00
Intelligent Platform Management Interface version 1.5 or 2.0,
and exports sensors and the watchdog through the
.Xr envsys 4
interface.
.Sh EVENTS
The
.Nm
driver is able to send events to
.Xr powerd 8
2009-05-04 23:16:41 +04:00
when a sensor's state has changed.
Intrusion sensors will send a
.Em critical
event when state is not ok.
Power Supply sensors will send a
.Em critical
event when the Power Supply unit is not installed and
.Em warning-over
when the Power Supply unit is installed but not powered on.
Fan, temperature and voltage sensors will send
.Em critical-over
or
.Em critical-under
when the value is very critical, or
.Em warning-over
or
.Em warning-under
if it's in a warning alert.
