CORETEMP(4) NetBSD Kernel Interfaces Manual CORETEMP(4)
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 Romero Pardines. NetBSD 5.0_RC4 December 21, 2007 NetBSD 5.0_RC4
