coretemp -- Intel Core on-die digital thermal sensor
coretemp* at cpu?
The coretemp driver provides support for the on-die digital thermal sen-
sor 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.
The coretemp driver is able to send a critical event to the powerd(8)
daemon. The script /etc/powerd/scripts/sensor_temperature will be exe-
cuted by the daemon (if running) when the limit has been reached.
