  • Method and apparatus for efficient submission of workload to a high performance graphics sub-system
    Patent number: 10410311
    Abstract: Embodiments provide for an apparatus comprising a graphics processing subsystem including one or more graphics engines and a graphics scheduler to schedule a submission queue of multiple work items for execution on the one or more graphics engines of the graphics processing subsystem. The graphics scheduler can be configured to build the submission queue via a write to a memory mapped address that is mapped to logic within the graphics processing subsystem and to explicitly submit the submission queue to the graphics engine after the build of the submission queue.

  • Hardware assist for privilege access violation checks
    Patent number: 10303902
    Abstract: Techniques are disclosed for processing rendering engine workload of a graphics system in a secure fashion, wherein at least some security processing of the workload is offloaded from software-based security parsing to hardware-based security parsing. In some embodiments, commands from a given application are received by a user mode driver (UMD), which is configured to generate a command buffer delineated into privileged and/or non-privileged command sections. The delineated command buffer can then be passed by the UMD to a kernel-mode driver (KMD), which is configured to parse and validate only privileged buffer sections, but to issue all other batch buffers with a privilege indicator set to non-privileged.

  • Position only shader context submission through a render command streamer
    Patent number: 10210655
    Abstract: By scheduling/managing workload submission to a position only shading pipe one can exploit parallelism with minimum impact to the software scheduler in some embodiments. An interface submits workloads to a slave engine running in one parallel pipe to assist a main engine running in another parallel pipe. Command sequences for each parallel pipe are separated to enable the slave engine to run ahead of the main engine. The slave engine is a position only shader and the main engine is a render engine.
