摘要： 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.

摘要： A method of data processing, the method comprising receiving, at a graphics processing unit (GPU), a command stream, the command stream including one or more commands to be performed by the GPU and at least one command stream marker, the at least one command stream marker indicating a workload type of the command stream, determining, by the GPU, an operation algorithm for the GPU based on the at least one command stream marker prior to executing the command stream, and executing, by the GPU, the command stream based on the operation algorithm.

摘要： Systems, methods, and apparatus for performing queries in a graphics processing system are disclosed. These systems, methods, and apparatus may be configured to read a running counter at the start of the query to determine a start value, wherein the running counter counts discrete graphical entities, read the running counter at the end of the query to determine an end value, and subtract the start value from the end value to determine a result.
