IPMI(4)			 BSD Kernel Interfaces Manual		       IPMI(4)

NAME
     ipmi — Intelligent Platform Management Interface driver

SYNOPSIS
     ipmi0 at mainbus?

DESCRIPTION
     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.

EVENTS
     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 criti‐
     cal, or warning-over or warning-under if it's in a warning alert.

SEE ALSO
     envsys(4), envstat(8), powerd(8), wdogctl(8)

HISTORY
     The ipmi driver first appeared in OpenBSD 3.9 and was then ported to
     NetBSD 4.0.

AUTHORS
     The ipmi driver was originally written by Jordan Hargrave and was ported
     to NetBSD by Manuel Bouyer ⟨bouyer@NetBSD.org⟩.
