Abstract: Self-tuning thread dispatch policies are described herein. According to one example, a self-tuning thread dispatch policy uses the relative execution time for GPU engines from previous frames to modify the thread dispatch policy for a subsequent frame. In one example, a graphics processing device includes command processing circuitry to receive commands for a render engine and a compute engine of the GPU to render and process frames of an application. The graphics processing device also includes circuitry to determine the usage of shared hardware resources by the render engine and the compute engine for one or more frames of the application. The number of threads to dispatch to the shared hardware resources for a next frame can then be adjusted for the render engine or the compute engine based on the usage of the shared hardware resources for the previous one or more frames.

Abstract: Various embodiments enable low frequency calculation of derived uniform values. A compiler can identify one or more portions of a shader that calculate a derived value based on an input value. For example, this portion may include instructions that use constant values, or the results of prior functions that used constant values. The constant values may include hardcoded values provided by the program (e.g., immediates) and/or other constant values. This portion of the shader can be extracted by the compiler and compiled into a first program. The compiler can compile the remainder of the shader into a second program that receives the derived uniform values from the first program. By extracting the portion(s) of the program that calculates a derived value into a separate program, the derived uniform value or values can be calculated at a lower frequency than if they were calculated for each pixel.
