Trip points must be set properly before switching to automatic fan speed
|
||||
control mode. The driver will perform basic integrity checks before
|
||||
actually switching to automatic control mode.
|
||||
|
||||
|
||||
Temperature offset attributes
|
||||
-----------------------------
|
||||
|
||||
The driver supports temp[1-3]_offset sysfs attributes to adjust the reported
|
||||
temperature for thermal diodes or diode-connected thermal transistors.
|
||||
If a temperature sensor is configured for thermistors, the attribute values
|
||||
are ignored. If the thermal sensor type is Intel PECI, the temperature offset
|
||||
must be programmed to the critical CPU temperature.
