US 10,311,626 B2 · System and method for identifying graphics workloads for dynamic allocation of resources among GPU shaders

Abstract

A GPU filters graphics workloads to identify candidates for profiling. In response to receiving a graphics workload for the first time, the GPU determines if the graphics workload would require the GPU shaders to use fewer resources than would be spent profiling and determining a resource allocation for subsequent receipts of the same or a similar graphics workload. The GPU can further determine if the shaders are processing more than one graphics workload at the same time, such that the performance characteristics of each individual graphics workload cannot be effectively isolated. The GPU then profiles and stores resource allocations for a plurality of shaders for processing the filtered graphics workloads, and applies those stored resource allocations when the same or a similar graphics workload is received subsequently by the GPU.

Dependent claims

A method comprising:

receiving at a plurality of shaders a first graphics workload;
in response to the plurality of shaders using less than a threshold amount of resources to process the first graphics workload,
storing a first workload identifier;
and
applying a default resource allocation to the plurality of shaders when a second graphics workload having the first workload identifier is subsequently received by the plurality of shaders;
and
in response to the plurality of shaders using more than the threshold amount of resources,
determining by a performance monitor a resource allocation for the first graphics workload;
storing the resource allocation and a second workload identifier that is different than the first workload identifier;
and
applying the resource allocation to the plurality of shaders when a second graphics workload having the second workload identifier is subsequently received by the plurality of shaders.
