Abstract: In one example, a system for managing power states can include a processor to detect a power state transition operation and detect historical callback information for each of a plurality of drivers of the system. The processor can also sort the plurality of drivers into a plurality of driver groups based on the historical callback information and execute the power state transition operation by transmitting a plurality of power state instructions for each driver to a plurality of processors based on the plurality of driver groups.
