| D | occ.rst | 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
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.

24 -----------
26 This driver implements sensor reading support for the energy and power meters
27 available on various IBM System X hardware through the BMC. All sensor banks
33 last BMC reset, and a power sensor that returns average power use over a
37 range of energy and power use registers, the power cap as set by the AEM
41 ----------------
43 The "power_cap" value displays the current system power cap, as set by the AEM
44 software. Setting the power cap from the host is not currently supported.
