IPMI(4) NetBSD Kernel Interfaces Manual IPMI(4)
ipmi -- Intelligent Platform Management Interface driver
ipmi0 at mainbus?
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 criti- cal, or warning-over or warning-under if it's in a warning alert.
envsys(4), envstat(8), powerd(8), wdogctl(8)
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 <bouyer@NetBSD.org>. NetBSD 9.0 September 8, 2008 NetBSD 9.0
