1 Kernel driver occ-hwmon
12 -----------
14 This driver supports hardware monitoring for the On-Chip Controller (OCC)
15 embedded on POWER processors. The OCC is a device that collects and aggregates
16 sensor data from the processor and the system. The OCC can provide the raw
20 manually if an "ibm,p8-occ-hwmon" compatible device is found under the
21 appropriate I2C bus node in the device-tree.
23 The P9 version of this driver is a client driver of the FSI-based OCC driver.
24 It will be probed automatically by the FSI-based OCC driver.
27 -------------
29 The following attributes are supported. All attributes are read-only unless
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
35 to the device driver, which must therefore export the sensor ID as-is.
