Methods, systems and apparatuses may provide for technology that triggers an idle state in a first command streamer in response to a request to reset a second command streamer that shares graphics hardware with the first command streamer. The technology may also determine an event type associated with the request and conduct the request based on the event type.

Graphics engine reset and recovery in a multiple graphics context execution environment

An apparatus and method for provisioning virtualized tile-based graphics processing circuitry. For example, one embodiment of an apparatus comprises: processing resources to process commands including graphics commands and generate results; resource partitioning circuitry to partition the processing resources into a plurality of tiles in accordance with a specified tile-based resource allocation policy; and graphics virtualization circuitry to perform tile-based allocation of the processing resources to a plurality of virtual machines in accordance with a specified virtualization policy, the virtual machines to be executed in a virtualized execution environment.

Apparatus and method for provisioning virtualized multi-tile graphics processing hardware

An apparatus and method for virtualized scheduling. For example, one embodiment of a graphics processing apparatus comprises: a graphics processor comprising a plurality of graphics processing engines, each of the graphics processing engines usable to execute graphics program code for a plurality of graphics contexts, each of the graphics contexts associated with a particular user mode driver (UMD); and a scheduler to schedule the graphics program code for execution on the plurality of graphics engines, the scheduler comprising an integrated context queue to store program code from all of the graphics contexts, the scheduler to select graphics processing engines to execute the program code from each context based on a detected load and/or availability of each graphics processing engine and to determine an order for executing the program code from each context based on relative priorities associated with the different contexts.

Apparatus and method for virtualized scheduling of multiple duplicate graphics engines

Apparatus and method for simultaneous command streamers. For example, one embodiment of an apparatus comprises: a plurality of work element queues to store work elements for a plurality of thread contexts, each work element associated with a context descriptor identifying a context storage region in memory; a plurality of command streamers, each command streamer associated with one of the plurality of work element queues, the command streamers to independently submit instructions for execution as specified by the work elements; a thread dispatcher to evaluate the thread contexts including priority values, to tag each instruction with an execution identifier (ID), and to responsively dispatch each instruction including the execution ID in accordance with the thread context; and a plurality of graphics functional units to independently execute each instruction dispatched by the thread dispatcher and to associate each instruction with a thread context based on its execution ID.

Method and apparatus for simultaneously executing multiple contexts on a graphics engine

Graphics processing systems and methods are described. A graphics processing apparatus may comprise one or more graphics processing cores, a shared buffer accessible to a user mode driver (UMD) associated with an application in an unprivileged domain, the UMD to write one or more commands to the shared buffer, and a controller parse a workload in the shared buffer to identify one or more commands in the workload, the workload added by the application executing in the unprivileged domain, associate a trigger with a command in the workload, transfer the workload to one or more components of the graphics processing apparatus for execution, and upon execution of the command associated with the trigger, sample the shared buffer to identify a new workload added to the shared buffer. The one or more components of the graphics processing apparatus automatically execute the new workload added to the shared buffer.

Efficiently enqueuing workloads from user mode to hardware across privilege domains

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.
