Method and Apparatus for Efficient Submission of Workload to a High Performance Graphics Sub-System

A non-transitory machine readable medium storing instructions which, when executed by one or more processors, causes the one or more processors to perform operations to schedule work items for one or more graphics engines within a graphics processing subsystem, the operations including:

• receiving an identifier for a batch of one or more work items for submission to a graphics engine;
• selecting which of the one or more graphics engines to which the batch of one or more work items is to be submitted;
• inserting the identifier for the batch of one or more work items into an element of a submission queue associated with a selected graphics engine;
• and
• explicitly submitting the elements in the submission queue by writing to a control register.

A graphics processing system comprising:

• a first processor including one or more graphics engines;
• a second processor coupled to the first processor on a single die;
• and
• a microcontroller including scheduling logic to schedule operations for the one or more graphics engines, the scheduling logic configured to schedule a submission queue of multiple work items for execution on the one or more graphics engines, the scheduling logic to build the submission queue via a write to a memory mapped address that is mapped to the first processor and explicitly submit the submission queue to the graphics engine after the build of the submission queue.
