Intel Core on-die digital thermal
sensor
SYNOPSIS
coretemp* at cpu?
DESCRIPTION
Thecoretemp 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.
