NAME
coretemp —
device driver for Intel Core on-die
digital thermal sensor
SYNOPSIS
To compile this driver into the kernel, place the following line in your kernel configuration file:
device coretempAlternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
coretemp_load="YES"
DESCRIPTION
Thecoretemp driver provides support for the on-die
digital thermal sensors, both core level and package level, for Intel Core and
newer CPUs. The values are exposed through the
HW_SENSORS
sysctl(3) tree. For example:
% sysctl hw.sensors hw.sensors.cpu0.temp0: 50.00 degC (node0 core0 temp), OK hw.sensors.cpu1.temp0: 50.00 degC (node0 core0 temp), OK hw.sensors.cpu2.temp0: 47.00 degC (node0 core1 temp), OK hw.sensors.cpu3.temp0: 47.00 degC (node0 core1 temp), OK hw.sensors.cpu_node0.temp0: 50.00 degC (node0 temp), OK
If the core or package temperature reaches critical level, a notify event will be sent using devctl(4).
