Abstract

Techniques are disclosed relating to affinity-based scheduling of graphics work. In disclosed embodiments, first and second groups of graphics processor sub-units may share respective first and second caches. Distribution circuitry may receive a software-specified set of graphics work and a software-indicated mapping of portions of the set of graphics work to groups of graphics processor sub-units. The distribution circuitry may assign subsets of the set of graphics work based on the mapping. This may improve cache efficiency, in some embodiments, by allowing graphics work that accesses the same memory areas to be assigned to the same group of sub-units that share a cache.
