From: "Edward A. James" <eajames@xxxxxxxxxx> This patchset adds a hwmon driver to support the OCC (On-Chip Controller) on the IBM POWER8 and POWER9 processors, from a BMC (Baseboard Management Controller). The OCC is an embedded processor that provides real time power and thermal monitoring. The driver provides an interface on a BMC to poll OCC sensor data, set user power caps, and perform some basic OCC error handling. It interfaces with userspace through hwmon. The driver is currently functional only for the OCC on POWER8 chips. Communicating with the POWER9 OCC requries FSI support.
Overall looks pretty good. There is the 0day hiccup (was that solved ?) and a few comments I made separately. It might make sense to add someone from IBM as maintainer. Thanks, Guenter
