The power allocator governor is a thermal governor that controls system and device power allocation to control temperature. Conceptually, the implementation divides the sustainable power of a thermal zone among all the heat sources in that zone. This governor relies on "power actors", entities that represent heat sources. They can report current and maximum power consumption and can set a given maximum power consumption, usually via a cooling device. The governor uses a Proportional Integral Derivative (PID) controller driven by the temperature of the thermal zone. The output of the controller is a power budget that is then allocated to each power actor that can have bearing on the temperature we are trying to control. It decides how much power to give each cooling device based on the performance they are requesting. The PID controller ensures that the total power budget does not exceed the control temperature.
