Abstract
Techniques are disclosed relating to handling page faults created by a processor unit. In some embodiments, such techniques may be used within the context of graphics processor units (GPUs) to reduce the chances that a page fault will result in a GPU-pipeline stall. In one embodiment, a processor includes a graphics processor pipeline and a memory management unit. The graphics processor pipeline includes a plurality of pipeline stages. The memory management unit is configured to determine that a first data request from a first of the plurality of pipeline stages causes a page fault, and to service requests from one or more others of the plurality of pipeline stages while the page fault is being serviced.
