SYNOPSIS

DESCRIPTION

The access to pchtherm data is made via the sysctl(8) interface:

dev.pchtherm.0.t0temp: 81.0C
dev.pchtherm.0.tahv: 83.0C
dev.pchtherm.0.talv: 30.0C

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.

Please check the PCH datasheets for more details.
