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 coretemp Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): coretemp_load="YES"

DESCRIPTION

The coretemp driver provides support for the on-die digital thermal sen- sors, both core level and package level, for Intel Core and newer CPUs. The values are exposed through the HW_SENSORS sysctl(3) tree. For exam- ple: %sysctl hw.sensors hw.sensors.cpu0.temp0: 50.00 degC (node0 core0), OK hw.sensors.cpu1.temp0: 50.00 degC (node0 core0), OK hw.sensors.cpu2.temp0: 47.00 degC (node0 core1), OK hw.sensors.cpu3.temp0: 47.00 degC (node0 core1), OK hw.sensors.cpu_node0.temp0: 50.00 degC (node0), OK If the core or package temperature reaches critical level, a notify event will be sent using devctl(4).
