Exposing power capping values as a sensor This implementation introduces support for power capping values provided by hwmon. Values are read from files with suffix cap, cap_max and cap_min and are exposed as properties of the interface xyz.openbmc_project.Sensor.Value The property Value is taken from the power[N]_cap file in a standard way. While the MaxValue and MinValue are periodically read from the corresponding files: power[N]_cap_max and power[N]_cap_min. If cap_max, cap_min files cannot be read properties MinValue/MaxValue are set to 0 unless the power is OFF then NaN is returned. For other types of files than ‘cap’ default CPUSensor MinValue, MaxValue values are used as it was before this change.

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.
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
