NAME

     coretemp -- Intel Core on-die digital thermal sensor


SYNOPSIS

     options INTEL_CORETEMP


DESCRIPTION

     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:

EVENTS

     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.


SEE ALSO

     envstat(4), powerd(8)


HISTORY

     The coretemp driver first appeared in FreeBSD 7.0.  And then was ported
     to NetBSD 5.0.
