# OpenPOWER OCC Control Service

This service will handle communications to the On-Chip Controller (OCC) on Power

processors. The OCC provides processor and memory temperatures, power readings,

power cap support, system power mode support, and idle power saver support. OCC

Control will be interfacing with the OCC to collect the temperatures and power

readings, updating the system power mode, setting power caps, and idle power

save parameters.

The service is started automatically when the BMC is started.

## Build Project

This project can be built with meson. The typical meson workflow is: meson

builddir && ninja -C builddir.

## Server

The server will start automatically after BMC is powered on.

Server status: `systemctl status org.open_power.OCC.Control.service`

To restart the service: `systemctl restart org.open_power.OCC.Control.service`

## Configuration

Service files are located in service_files subdirectory.
