GPU resource priorities based on hardware utilization

A non-transitory program storage device comprising instructions stored thereon to cause one or more processors to:

• measure, for a first process executing on a graphics processor, a first utilization value for first hardware resources of the graphics processor after each of a first plurality of sample time intervals, wherein each first utilization value is indicative of the first process' use of the first hardware resources during each respective sample time interval of the first plurality of sample time intervals;
• measure, for at least one second process executed concurrently with the first process, a second utilization value for second hardware resources of the graphics processor after each of the first plurality of sample time intervals, wherein each second utilization value is indicative of the at least one second process' use of the second hardware resources during each respective sample time interval of the first plurality of sample time intervals;
• combine, after the first plurality of sample time intervals, the first utilization values to generate a first combined utilization value for the first process;
• combine, after the first plurality of sample time intervals, the second utilization values for each of the at least one second processes to generate a second combined utilization value for each of the at least one second processes;
• normalize the first combined utilization value, by dividing the first combined utilization value by the sum of the first combined utilization value and each of the at least one second combined utilization values, to generate a normalized first utilization value;
• compare the normalized first utilization value to a target value and modify a first priority of the first process based on results of the comparison;
• and
• allocate hardware resources of the second hardware resources of the graphics processor to the first process based on the modified first priority.

An electronic device, comprising:

• means for measuring, for a first process executing on the GPU, a first utilization value for the first hardware resources of the GPU after each of a first plurality of sample time intervals, wherein each first utilization value is indicative of the first process' use of the first hardware resources during each respective sample time interval of the first plurality of sample time intervals;
• means for measuring, for at least one second process executing on the GPU executed concurrently with the first process, a second utilization value for the second hardware resources of the GPU after each of the first plurality of sample time intervals, wherein each second utilization value is indicative of the at least one second process' use of the second hardware resources during each respective sample time interval of the first plurality of sample time intervals;
• means for combining, after the first plurality of sample time intervals, the first utilization values to generate a first combined utilization value for the first process;
• means for combining, after the first plurality of sample time intervals, the second utilization values for each of the at least one second processes to generate a second combined utilization value for each of the at least one second processes;
• means for normalizing the first combined utilization value, by dividing the first combined utilization value by the sum of the first combined utilization value and each of the at least one second combined utilization values, to generate a normalized first utilization value;
• means for comparing the normalized first utilization value to a target value and means for modifying a first priority of the first process based on results of said comparing;
• and
• means for allocating hardware resources of the second hardware resources of the graphics processor to the first process based on the modified first priority.
