A method of graphics processing comprising receiving, at a graphics processing unit (GPU), a command stream, the command stream including one or more commands to be performed by the GPU and at least one command stream hint, the at least one command stream hint providing a characterization of a workload of the command stream, performing, by the GPU, a power management process based on the at least one command stream hint prior to executing the command stream, and executing, by the GPU, the command stream.

Characterizing GPU workloads and power management using command stream hinting

Techniques are described in which a processor determines how busy a graphics processing unit (GPU) was in rendering a current fame based on a time interval between when the GPU completed the rendering of the current frame and when the GPU completed the rendering of a previous frame that immediately precedes the current frame. The processor sets a clock rate of the GPU based on the determination of how busy the GPU was in rendering the current frame.
