.Sh NAME
.Nm coretemp
.Nd Intel Core on-die digital thermal sensor
.Sh SYNOPSIS
.Cd "options INTEL_CORETEMP"
.Sh DESCRIPTION
The
.Nm
driver provides support for the on-die digital thermal sensor present
on Intel Core and newer CPUs.
.Pp
The
.Nm
driver reports each core's temperature through the
.Xr envsys 4
API. The driver has only 1 temperature sensor:
.Bl -column "Sensor" "Units" "Typical" -offset indent
.It Sy "Sensor" Ta Sy "Units" Ta Sy "Typical Use"
.It Li "sensor0" Ta "uK" Ta "cpuN temperature"
.El
.Sh EVENTS
The
.Nm
driver is able to send a
.Em critical
event to the
.Fa /etc/powerd/scripts/sensor_temperature
.Xr powerd 8
script (if running) when the temperature has reached a critical state.
.Sh SEE ALSO
.Xr envstat 4 ,
.Xr powerd 8
.Sh HISTORY
