Abstract
Techniques are disclosed relating to discarding graphics work, e.g., to free execution resources for higher-priority work. Control circuitry may distribute a first set of graphics work to a set of graphics processor sub-units and initiate a priority inversion signal in response to a determination that a second set of graphics work has a higher priority than the first set of graphics work and is blocked by the first set of graphics work. In response to a discard signal, control circuitry may discard results of the first set of graphics work from the multiple distributed hardware slots, including to: free one or more memory pages written to by the first set of graphics work and provide a stand-in memory page.
