33 .Nd device driver for Intel Core on-die digital thermal sensor
35 To compile this driver into the kernel,
36 place the following line in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
42 Alternatively, to load the driver as a
43 module at boot time, place the following line in
45 .Bd -literal -offset indent
51 driver provides support for the on-die digital thermal sensors,
52 both core level and package level,
53 for Intel Core and newer CPUs.
54 The values are exposed through the
59 .Bd -literal -offset indent
61 hw.sensors.cpu0.temp0: 50.00 degC (node0 core0 temp), OK
62 hw.sensors.cpu1.temp0: 50.00 degC (node0 core0 temp), OK
63 hw.sensors.cpu2.temp0: 47.00 degC (node0 core1 temp), OK
64 hw.sensors.cpu3.temp0: 47.00 degC (node0 core1 temp), OK
65 hw.sensors.cpu_node0.temp0: 50.00 degC (node0 temp), OK
68 If the core or package temperature reaches critical level,
69 a notify event will be sent using
