65 .Bl -tag -width ".Va dev.pchtherm.%d.pch_hot_level"
66 .It Va dev.pchtherm.%d.temperature
67 Is the read-only value of the current temperature read by the sensor.
68 .It Va dev.pchtherm.%d.ctt
69 When the system reaches this temperature, it will shut down.
70 This will not appear when this feature is disabled and locked down.
71 .It Va dev.pchtherm.%d.t0temp
72 When temperature is under this value, system will be in T0 state.
73 .It Va dev.pchtherm.%d.t1temp
74 When temperature is over
76 and under this value, system will be in T1 state.
77 .It Va dev.pchtherm.%d.t2temp
78 When temperature is over
80 and under this value, system will be in T2 state.
81 Over this value, system will be in T3 state.
82 .It Va dev.pchtherm.%d.talv
84 This will not appear when sensor enable bit is locked down and the value is zero(which will show -50.0C).
85 .It Va dev.pchtherm.%d.tahv
87 This will not appear when sensor enable bit is locked down and the value is zero(which will show -50.0C).
88 .It Va dev.pchtherm.%d.pmtemp
89 Sensor Power management temperature.
90 Under this temperature, sensor will idle during
93 .It Va dev.pchtherm.%d.pmtime
94 Sensor idle duration when low temperature.
95 .It Va dev.pchtherm.%d.pch_hot_level
96 When temperature is higher than this value, PCHHOT# pin will assert.
97 This value is not appear when this feature is disabled and locked down.
100 Please check the PCH datasheets for more details.
103 All values are read-only.
104 And it do not support event interrupt for now.
