Adaptive power control loop

A non-transitory computer readable medium embodying a set of executable instructions, the set of executable instructions to manipulate a processor to:

• identify a first performance metric associated with processing a current workload at a graphics processing unit (GPU) has a first relationship to a threshold for a number of consecutive measurement cycles, wherein the number of consecutive measurement cycles includes a current measurement cycle and at least one previous measurement cycle, the first performance metric indicative of GPU performance while processing the current workload;
• in response to the number of consecutive measurement cycles exceeding one of an up-hysteresis level and a down-hysteresis level,
• determine an estimated optimization to be applied to the GPU for a future measurement cycle;
• and
• adjust a power level setting at the GPU for the future measurement cycle by adjusting one of the up-hysteresis level and the down-hysteresis level based on the estimated optimization.

A device, comprising:

• a graphics processing unit (GPU) comprising:
• a graphics pipeline including a plurality of compute units (CUs);
• a performance module to:
• identify a first performance metric associated with processing a current workload at the GPU has a first relationship with a threshold for a number of consecutive measurement cycles, wherein the consecutive number of consecutive measurement cycles includes a current measurement cycle and at least one previous measurement cycle, the first performance metric indicative of GPU performance while processing the current workload;
• in response to the number of consecutive measurement cycles exceeding one of an up-hysteresis level and a down-hysteresis level, determine, based on data representing a hardware configuration of the device, an estimated optimization to be applied to the GPU for a future measurement cycle;
• and
• a power and clock controller module to adjust a power level setting at the GPU based on the estimated optimization by adjusting one of the up-hysteresis level and the down-hysteresis level.
