Abstract: Methods, systems, and devices for graphic processing are described. The methods, systems, and devices may include or be associated with identifying a graphics instruction, determining that the graphics instruction is alias enabled for the device, partitioning an alias lookup table into one or more slots, allocating a slot of the alias lookup table based on the partitioning and determining that the graphics instruction is alias enabled, generating an alias instruction based on allocating the slot of the alias lookup table and determining that the graphics instruction is alias enabled, and processing the alias instruction.

Abstract: This disclosure describes a device configured to generate a primitive visibility stream that indicates whether respective primitives of a set of primitives are visible when rendered and to generate, based on the primitive visibility stream, a draw call visibility stream that indicates whether respective draw calls for rendering the set of primitives include instructions for rendering visible primitives of the set of primitives. Based on the draw call visibility stream indicating that a respective draw call does not include instructions for rendering visible primitives, the device is further configured to drop the respective draw call. Based on the draw call visibility stream indicating that the respective draw call includes instructions for rendering visible primitives, the device is further configured to execute the respective draw call.

Abstract: This disclosure describes techniques for executing shader programs in a graphics processing unit (GPU). In some examples, the techniques for executing shader programs may include executing, with a shader unit of a graphics processor, a shader program that performs vertex shader processing and that generates multiple output vertices for each input vertex that is received by the shader program. In further examples, the techniques for executing shader programs may include executing a merged vertex/geometry shader program using a non-replicated mode of execution. The non-replicated mode of execution may involve assigning each of a plurality of primitives to one merged vertex/geometry shader program instance per primitive and causing each of the instances to output a plurality of vertices. In additional examples, the techniques for executing shader programs may include techniques for selecting one of a non-replicated mode and a replicated mode for executing a merged vertex/geometry shader program.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for fast incremental shared constants. In aspects, a CPU may determine/update shared constant data for a first draw call of a plurality of draw calls. The shared constant data, which may correspond to at least one shader, may be updated based on a draw call update for the first draw call. The CPU may communicate the updated shared constant data for the first draw call to a GPU. The GPU may receive, in at least one register, the updated shared constant data from the CPU and configure the at least one register based on the updated shared constant data corresponding to the draw call update of the first draw call of the plurality of draw calls.

Abstract: This disclosure describes a method and apparatus for performing tessellation in a graphics process. A graphics processing unit may be configured to determine tessellation factors for a first patch of the graphics data, determine, based on the tessellation factors, that a first edge of an outermost ring of the first patch will produce only degenerated sub-primitives, and skip performing tessellation for the first edge. A graphics processing unit may determine that a second edge of the outermost ring of the first patch will produce at least some normal sub-primitives, and perform tessellation for the second edge to produce output primitives.

Abstract: Techniques are described with respect to preemption in which a graphics processing unit (GPU) may execute a first set of commands in response to receiving a draw call, the draw call defining a plurality of primitives that are to be rendered by the first set of commands, receive a preemption notification during execution of the first set of commands, and preempt the execution of the first set of commands, prior to completing the execution of the first set of commands to render the plurality of primitives of the draw call, for executing a second set of commands.

Abstract: In an example, a method for rendering graphics data includes rendering pixels of a first bin of a plurality of bins, wherein the pixels of the first bin are associated with a first portion of an image, and rendering, to the first bin, one or more pixels that are located outside the first portion of the image and associated with a second, different bin of the plurality of bins. The method also includes rendering the one or more pixels associated with the second bin to the second bin, such that the one or more pixels are rendered to both the first bin and the second bin.

Additionally, aspects of the present disclosure can perform, with an ALU component, a matrix multiplication operation using the set of input data and the set of weight data to generate an output matrix. Further, aspects of the present disclosure can store the output matrix at a general purpose register accessible to the ALU component.
