coretemp -- Intel Core on-die digital thermal sensor
The coretemp driver provides support for the on-die digital thermal sen-
sor present on Intel Core and newer CPUs.
The coretemp driver reports each core's temperature through the envsys(4)
API. The driver has only 1 temperature sensor:
Sensor Units Typical Use
sensor0 uK cpuN temperature
The coretemp driver is able to send a critical event to the
/etc/powerd/scripts/sensor_temperature powerd(8) script (if running) when
the temperature has reached a critical state.
The coretemp driver first appeared in FreeBSD 7.0. And then was ported
to NetBSD 5.0.
The coretemp driver was written by Rui Paulo <rpaulo@FreeBSD.org> as part
of a Google Summer of Code project. It was adapted to NetBSD by Juan
