NAME
coretemp —
Intel Core on-die digital
thermal sensor
SYNOPSIS
coretemp* at cpu?
DESCRIPTION
The
coretemp driver provides support for the on-die digital
thermal sensor present on Intel Core and newer CPUs.
The temperatures can be observed by using the
envsys(4) API or the
envstat(8) command.
Temperatures are reported for each core separately.
EVENTS
The
coretemp driver is able to send a
critical event to the
powerd(8) daemon. The script
/etc/powerd/scripts/sensor_temperature will be executed by
the daemon (if running) when the limit has been reached.
