Apparatus and method for scheduling graphics processing resources

A graphics processing apparatus comprising:

• first graphics processing resources to process graphics commands and execute graphics data;
• workload scheduling circuitry to schedule workloads for execution on the first graphics processing resources;
• and
• workload queuing circuitry to implement a local queue to store local workload entries, each local workload entry associated with a locally-submitted workload and an external workload queue to store external workload entries, each external workload entry associated with an externally-submitted workload submitted for execution by an external graphics processing apparatus;
• the workload scheduling circuitry to schedule the locally-submitted workloads identified in the local queue and externally-submitted workloads identified in the external workload queue for processing by specified portions of the first graphics processing resources.

A method comprising:

• receiving a first plurality of graphics workloads submitted locally on a graphics processing apparatus;
• generating an entry for each of the first plurality of graphics workloads in a local workload queue;
• receiving a second plurality of graphics workloads from one or more external graphics processing devices;
• generating an entry for each of the second plurality of graphics workloads in an external workload queue;
• and
• scheduling the first plurality of graphics workloads and the second plurality of graphics workloads on specified portions of the first graphics processing resources in accordance with a scheduling policy.

A machine-readable medium having program code stored thereon which, when executed by a machine, causes the machine to perform the operations of:

• receiving a first plurality of graphics workloads submitted locally on a graphics processing apparatus;
• generating an entry for each of the first plurality of graphics workloads in a local workload queue;
• receiving a second plurality of graphics workloads from one or more external graphics processing devices;
• generating an entry for each of the second plurality of graphics workloads in an external workload queue;
• and
• scheduling the first plurality of graphics workloads and the second plurality of graphics workloads on specified portions of the first graphics processing resources in accordance with a scheduling policy.
