摘要： In accordance with some embodiments, a command streamer may use a cache of programmable size to cache commands to improve memory bandwidth and reduce latency. The size of the command cache may be programmably set by the command streamer.

摘要： A mechanism for command stream processing is described. A method of embodiments, as described herein, includes fetching cache lines from a memory to fill command first in first out buffer (FIFO), wherein the fetched cachelines an overfetching of data necessary to process a command, a first parser to fetch and execute batch commands stored in the command FIFO and a second parser to fetch commands and execute the batch commands and non-batch commands stored in the command FIFO.

摘要： An apparatus and method are described for culling commands in a tile-based renderer. For example, one embodiment of an apparatus comprises: a command buffer to store a plurality of commands to be executed by a render pipeline to render a plurality of tiles; visibility analysis circuitry to determine per-tile visibility information for each of the plurality of tiles and to store the visibility information for a first tile in a first storage, the visibility information specifying either that all of the commands associated with rendering the first tile can be skipped or identifying individual commands associated with rendering the first tile that can be skipped; and a render pipeline to read the visibility information from the first storage to determine whether to execute or skip one or more of the commands from the command buffer to render the first tile.

摘要： 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.

摘要： Systems, apparatuses and methods may provide for associating a first instruction pointer with an IF block of a primary IF-ELSE conditional construct associated with a thread and activating a second instruction pointer in response to a dependency associated with the IF block. Additionally, the second instruction pointer may be associated with an ELSE block of the primary IF-ELSE conditional construct. In one example, the IF block and the ELSE block are executed, via the first instruction pointer and the second instruction pointer, one or more of independently from or parallel to one another.

摘要： Programmable predication logic in command streamer instruction execution is described. In one example, the invention includes a method that includes receiving batch buffer execution start command at a command streamer, the batch buffer containing executable instructions, determining whether predication has been enabled for the instructions using the start command, if predication has been enabled, then comparing a predication condition to values stored in a predication register, and if the condition is satisfied by the predication register values, then executing the batch buffer.

摘要： 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. A graphics processing unit (GPU) can receive the privilege-designated batch buffers from the KMD, and is configured to disallow execution of any privileged command from a non-privileged batch buffer, while any privileged commands from privileged batch buffers are unrestricted by the GPU
