Abstract: A mechanism is described for facilitating efficient graphics command generation and execution for improved graphics performance at computing devices. A method of embodiments, as described herein, includes detecting an application programming interface (API) call to perform a plurality of transactions, where the API call is issued by an application at a first command buffer, where the plurality of transactions include a first set of transactions and a second set of transactions. The method may further include creating a second command buffer and appending the second command buffer to the first command buffer, where creating further includes separating the first set transactions from the second set of transactions. The method may further include executing, via the second command buffer, the first set of transactions, prior to executing the first set of transactions.

Abstract: A mechanism is described for facilitating efficient processing of graphics commands at computing devices. A method of embodiments, as described herein, includes detecting a current object representing a bundled state of graphics commands in a command list to be processed at a graphics processor of a computing device, and evaluating the current object to determine a previous object bound to a first set of the graphics commands, where the first set of the graphics commands is associated with a first command state corresponding to the previous object. The method may further include copying a second set of the graphics commands to a command buffer associated with the command list, where the second set of the graphics commands represents a remainder of the graphics commands in the command list upon excluding the first set of the graphics commands. The method may further include facilitating the graphics processor to execute the second set of the graphics commands from the command buffer.

Abstract: 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.

Abstract: Various embodiments are presented herein that may allow an application direct access to graphical processing unit memory. An apparatus and a computer-implemented method may include accessing allocated graphical processing unit memory of a second resource via a link from a first resource. The allocated graphical processing unit memory may be mapped into one or more page tables of a central processing unit. A virtual address of the graphical processing unit memory from the one or more page tables of the central processing unit may be sent to the application.

Abstract: Methods and apparatus relating to reducing memory latency in graphics operations are described. In an embodiment, uniform data is transferred from a buffer to a General Register File (GRF) of a processor based at least in part on information stored in a gather table. The uniform data comprises data that is uniform across a plurality of primitives in a graphics operation. Other embodiments are also disclosed and claimed.

Abstract: The same set of render commands can be re-executed for each of a plurality of tiles making up a graphic scene to be rendered. Each time the list of commands is executed, the way the commands are executed may be modified based on information received from tile pre-processing. Specifically, a jump if command may be inserted into the command list. When this command is encountered, a determination is made, based on information received from tile pre-processing pipeline, whether to execute the command for the next primitive or not. If the next primitive is to be culled then the command for the next primitive is not executed and the flow moves past that command. If the next primitive is to be executed then the jump is not implemented. This enables avoiding reloading the same list of commands over and over for every tile.

Abstract: Various embodiments are presented herein that may reduce the workload of a system tasked with delivering frames of video data to a display generated by applications executing within the system. Applications executing within the system may generate new frames of video content at a specified frame rate known as frames per second (FPS). The CPU and/or GPU may be responsible for actually generating the frames at the specified FPS. These frames are then delivered to a display communicatively coupled with the system for rendering. Reducing the frame rate (FPS) may reduce the work being performed by the system because fewer frames may be generated within a given time period. This may be especially advantageous when the system is operating on battery power because it can extend the life of the battery.

Abstract: By scheduling/managing workload submission to a POSH pipe one can exploit parallelism with minimum impact to the software scheduler in some embodiments.

Abstract: The introduction of an “out-of-memory” marker in the sorted tile geometry sequence for a tile may aid in handling out-of-memory frames. This marker allows hardware to continue rendering using the original data stream instead of the sorted data stream. This enables use of the original data stream allows the system to continue rendering without requiring any driver intervention. During the visibility generation/sorting phase, the number of memory pages required for storing the data for a rendering pass is continuously tracked. This tracking includes tracking the pages that are required even if the hardware had not run out-of-memory. This information can be monitored by a graphics driver and the driver can provide more memory pages for the system to work at full efficiency.

Abstract: An apparatus and method are described for asynchronous tile-based rendering control. In one embodiment of the invention, there is a delay between when the graphics driver queues the GPU commands for rendering and when the GPU begins executing. During this delay, the graphics driver receives additional information or data about whether cache evictions may be inhibited. As such, it allows the graphics driver to defer the cache eviction control of its render cache until it has this extra information. By doing so, it reduces the memory bandwidth required for rendering 3D graphics applications and in turn reduces the power consumption of the GPU.

Abstract: A mechanism is described for facilitating dynamic runtime transformation of graphics processing commands for improved graphics performance on computing devices. A method of embodiments, as described herein, includes detecting a command stream associated with an application, where the command stream includes dispatches. The method may further include evaluating processing parameters relating to each of the dispatches, where evaluating further includes associating a first plan with one or more of the dispatches to transform the command stream into a transformed command stream. The method may further include associating, based on the first plan, a second plan to the one or more of the dispatches, where the second plan represents the transformed command stream. The method may further include executing the second plan, where execution of the second plan includes processing the transformed command stream in lieu of the command stream.

Abstract: For a given texture address, a multi-mode texture sampler fetches and reduces texture data with a multi-mode filter accumulator suitable for providing a weighted average over a variety of filter footprints. A multi-mode texture sampler is configurable to provide both a wide variety of footprints and allow for a filter footprint significantly wider than the bi-linear (2×2 texel) footprint. In embodiments, filter coefficients specifying a weighting for each texel in a flexible footprint are cached from coefficient tables stored in memory. Techniques and systems are provided for dynamic allocation, update and handling of weighting coefficient tables as resources independent of sampler state.
