The
pchtherm
driver provides access to sensor data and configuration
installed in Intel PCH chipset.
pchtherm
configuration register.
The access to
pchtherm
data is made via the
sysctl(8)
interface:
dev.pchtherm.0.ctt: 115.0C
dev.pchtherm.0.temperature: 28.5C
dev.pchtherm.0.t2temp: 91.0C
dev.pchtherm.0.t1temp: 86.0C
dev.pchtherm.0.t0temp: 81.0C
dev.pchtherm.0.tahv: 83.0C
dev.pchtherm.0.talv: 30.0C
dev.pchtherm.0.pmtime: 32

dev.pchtherm.%parent:
|
| dev.pchtherm.%d.temperature
|
| |
Is the read-only value of the current temperature read by the sensor.
|
| dev.pchtherm.%d.ctt
|
| |
When the system reaches this temperature, it will shut down.
This will not appear when this feature is disabled and locked down.
|
| dev.pchtherm.%d.t0temp
|
| |
When temperature is under this value, system will be in T0 state.
|
| dev.pchtherm.%d.t1temp
|
| |
When temperature is over
t0temp
and under this value, system will be in T1 state.
|
| dev.pchtherm.%d.t2temp
|
| |
When temperature is over
t1temp
and under this value, system will be in T2 state.
Over this value, system will be in T3 state.
|
| dev.pchtherm.%d.talv
|
| |
Lower alart value.
This will not appear when sensor enable bit is locked down and the value is zero(which will show -50.0C).
|
| dev.pchtherm.%d.tahv
|
| |
High alart value.
This will not appear when sensor enable bit is locked down and the value is zero(which will show -50.0C).
|
| dev.pchtherm.%d.pmtemp
|
| |
Sensor Power management temperature.
Under this temperature, sensor will idle during
pmtime
second.
|
| dev.pchtherm.%d.pmtime
|
| |
Sensor idle duration when low temperature.
|
| dev.pchtherm.%d.pch_hot_level
|
| |
When temperature is higher than this value, PCHHOT# pin will assert.
This value is not appear when this feature is disabled and locked down.
