Abstract
This disclosure is directed to deferred preemption techniques for scheduling graphics processing unit (GPU) command streams for execution on a GPU. A host CPU is described that is configured to control a GPU to perform deferred-preemption scheduling. For example, a host CPU may select one or more locations in a GPU command stream as being one or more locations at which preemption is allowed to occur in response to receiving a preemption notification, and may place one or more tokens in the GPU command stream based on the selected one or more locations. The tokens may indicate to the GPU that preemption is allowed to occur at the selected one or more locations. This disclosure further describes a GPU configured to preempt execution of a GPU command stream based on one or more tokens placed in a GPU command stream.
