.Sh NAME
.Nm itherm
.Nd Intel 3400 temperature sensor
.Sh SYNOPSIS
.Cd "itherm* at pci?"
.Sh DESCRIPTION
The
.Nm
driver provides support for several sensors found in Intel 3400 and 5 series
chipsets.
.Pp
The sensors currently exposed via the
.Xr sysctl 8
interface are:
.Bl -column "CPU power cons." "Units" "Typical Use" -offset indent
.It Sy "Sensor" Ta Sy "Units" Ta Sy "Typical Use"
.It Li "Thermometer" Ta "degC" Ta "Temperature"
.It Li "Core 1" Ta "degC" Ta "Temperature"
.It Li "Core 2" Ta "degC" Ta "Temperature"
.It Li "CPU power cons." Ta "Watts" Ta "Power usage"
.It Li "CPU/GPU Max" Ta "degC" Ta "Temperature"
.It Li "DIMM 1" Ta "degC" Ta "Temperature"
.It Li "DIMM 2" Ta "degC" Ta "Temperature"
.It Li "DIMM 3" Ta "degC" Ta "Temperature"
.It Li "DIMM 4" Ta "degC" Ta "Temperature"
.It Li "GPU abs." Ta "degC" Ta "Temperature"
.It Li "PCH abs." Ta "degC" Ta "Temperature"

.Sh HISTORY
The
.Nm
driver first appeared in
.Ox 4.8 .
.Sh AUTHORS
The
.Nm
driver was written by
.An Mike Larkin Aq mlarkin@openbsd.org .
.Sh CAVEATS
Not all sensors are wired on every machine, so the list of
sensors shown in
.Xr sysctl 8
may not show all the sensors listed above.
Furthermore, the
.Nm
driver will flag sensors as invalid if they report bogus data.
