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.

Abstract: Methods and apparatus to improve shared memory efficiency are described. In an embodiment, a first version of a code to access one or more registers as shared local memory is compiled. A second version of the same code is also compiled to access a cache as the shared local memory. The first version of the code is executed in response to comparison of a work group size of the code with a threshold value. Other embodiments are also disclosed and claimed.
