Docc.rst16 sensor data from the processor and the system. The OCC can provide the raw
17 sensor data as well as perform thermal and power management on the system.
32 The OCC sensor ID is an integer that represents the unique identifier of the
33 sensor with respect to the OCC. For example, a temperature sensor for the third
34 DIMM slot in the system may have a sensor ID of 7. This mapping is unavailable
35 to the device driver, which must therefore export the sensor ID as-is.
37 Some entries are only present with certain OCC sensor versions or only on
42 OCC sensor ID.
