36 .Nd device driver for memory thermal sensor
38 To compile this driver into the kernel,
39 place the following lines in your kernel configuration file:
40 .Bd -ragged -offset indent
46 Alternatively, to load the driver as a
47 module at boot time, place the following line in
49 .Bd -literal -offset indent
55 driver provides support for the memory thermal sensor.
56 The values are exposed through the
61 .Bd -literal -offset indent
63 hw.sensors.dimm0.temp0: 40.00 degC (node0 chan0 DIMM0 temp), OK
64 hw.sensors.dimm1.temp0: 39.00 degC (node0 chan1 DIMM0 temp), OK
67 The DIMM location and configurable critical temperature thresholds
68 are exposed through hw.dimminfo
72 .Bd -literal -offset indent
74 hw.dimminfo.dimm0.node: 0
75 hw.dimminfo.dimm0.chan: 0
76 hw.dimminfo.dimm0.slot: 0
77 hw.dimminfo.dimm0.temp_hiwat: 93
78 hw.dimminfo.dimm0.temp_lowat: 88
79 hw.dimminfo.dimm1.node: 0
80 hw.dimminfo.dimm1.chan: 1
81 hw.dimminfo.dimm1.slot: 0
82 hw.dimminfo.dimm1.temp_hiwat: 93
83 hw.dimminfo.dimm1.temp_lowat: 88
86 If the temperature goes above the configured critical temperature threshold
88 a notify event will be sent using
93 driver supports the following memory thermal sensors:
97 Intel E5 v2 memory thermal sensors
99 Intel E5 v3 memory thermal sensors
101 Intel E3 v3 memory thermal sensors
103 Intel Core i3/i5/i7 Haswell thermal sensors
