Abstract: Methods and apparatus relating to advanced graphics Power State management are described. In one embodiment, measurement logic detects information about idle transitions and active transitions of a power-well of a processor. In turn, determination logic determines performance loss and/or energy gain based at least in part on the detected information and power-on latency of the power-well of the processor. Other embodiments are also disclosed and claimed.

Abstract: One or more system, apparatus, method, and computer readable media is described below for power management of one or more graphics processor resources. In some embodiments, a graphics processor context associated with an application an including power-related hardware configuration and control parameters is stored to memory. In some embodiments, graphics processor contexts are switched in and out as different application workloads are processed by resources of the graphics processor. In some embodiments, power-performance management algorithms are grouped and sequentially executed in ordered phases of a control loop to generate a compatible set of control parameter requests. Once finalized, the set is output as requests to graphics processor hardware and/or updates to stored graphics processor contexts.

Abstract: Methods and apparatus relating to techniques for runtime flip stability characterization are described. In an embodiment, logic circuitry determines the amount of work to be performed by a processor to render a pattern during each of a plurality of Vertical blank (Vblank) intervals. Memory stores information corresponding to a workload to be executed by the processor during each of the plurality of Vblank intervals. An operating frequency of the processor may then be modified based at least in part on analysis of the stored information to indicate which of the plurality of Vblank intervals would provide an improved stability for rendering the pattern. Other embodiments are also disclosed and claimed.

Abstract: Methods and apparatus relating to techniques for dynamically selecting optimum graphics logic frequency and/or graphics logic power gating configuration are described. In an embodiment, multi-rate control logic determines processor active slice count and processor frequency based at least in part on a target Frames Per Second (FPS) value and a current FPS value. The multi-rate control logic includes slow rate control logic to determine slice gating and operating frequency and a fast rate control logic to determine operating frequency of the processor. Other embodiments are also disclosed and claimed.
