NAME

     tm121temp -- Texas Instruments TMP121 temperature sensor

SYNOPSIS

     tm121temp0 at spi? slave 0

DESCRIPTION

     The tm121temp driver provides support for the Texas Instruments (formerly Burr-Brown) TMP121 temperature sensor with the envsys(4) API.
     These devices are connected to the host system with spi(4) or Microwire 4-wire serial busses.  The tm121temp is capable of measuring tempera-
     tures with a 2 degree accuracy over the frame from -40 to 125 Celsius.  Temperatures are reported with a granularity of 625 microKelvins.

     tm121temp devices can transfer information at up to 10MHz, and support SPI mode 0.

     The device reports itself with envsys(4) using the generic device name.  This name can be overridden, by specifying an alternate name in the
     device property ``envsys-description''.

HISTORY

     The tm121temp driver was written by Garrett D'Amore and first appeared in NetBSD 4.0.

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 sen-
     sors 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 critical, or warning-over or warning-under if it's in a warning alert.

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>.
