Adding support for power sensor and average values in CPU domain.

Current implementation of CPUSensor exposes on dbus only temperature sensors.
This change allows it to expose also power values under a new object
path: /xyz/openbmc_project/sensors/power/

It also introduce support for the average values and their thresholds.

Tested:
    After applying this change the same CPU sensors and their thresholds
    values are visible on dbus.
    Plus additional power sensor appears when available in system.

dbus-sensors

dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.

key features

  • runtime re-configurable from d-bus (entity-manager or the like)

  • isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible

  • async single-threaded: uses sdbusplus/asio bindings

  • multiple data inputs: hwmon, d-bus, direct driver access
