.Nm coretemp
|
|
.Nd Intel Core on-die digital thermal sensor
|
|
.Sh SYNOPSIS
|
|
.Cd "options INTEL_CORETEMP"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the on-die digital thermal sensor present
|
|
on Intel Core and newer CPUs.
|
|
.Pp
|
|
The temperatures can be observed by using the
|
|
.Xr envsys 4
|
|
.Tn API
|
|
or the
|
|
.Xr envstat 8
|
|
command.
|
|
Temperatures are reported for each core separately.
|
|
.Sh EVENTS
|
|
The
|
|
.Nm
|
|
driver is able to send a
|
|
.Em critical
|
|
event to the
|
|
.Xr powerd 8
|
|
daemon.
|
|
The script
|
|
.Fa /etc/powerd/scripts/sensor_temperature
|
|
will be executed by the daemon (if running) when the limit has been reached.
