H A Docc.rst1 Kernel driver occ-hwmon
12 -----------
14 This driver supports hardware monitoring for the On-Chip Controller (OCC)
16 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.
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.
