Abstract: The present disclosure relates to methods and apparatus for graphics processing. Aspects of the present disclosure can determine a portion of a display area, where the portion of the display area is determined based on display content of the display area. Further, aspects of the present disclosure can communicate display information corresponding to the determined portion of the display area. Additionally, aspects of the present disclosure can update the display information corresponding to the determined portion of the display area. Aspects of the present disclosure can also communicate the updated display information corresponding to the determined portion of the display area. Aspects of the present disclosure can also render at least some display content of the display area corresponding to the determined portion of the display area. In some aspects, the updated display information can be based on the rendered display content of the display area.

Abstract: The present disclosure provides for systems and methods to process a non-resident page that may include attempting to access the non-resident page, an address for the non-resident page pointing to a memory page containing default values, determining that the non-resident page should not cause a page fault based on an indicator indicating that a particular non-resident page should not generate a page fault, returning an indication that a memory read did not translate and returning the default value when the access of the non-resident page is a read and the non-resident page should not cause a page fault. Another example may discontinue a write when the access of the non-resident page is a write and the non-resident page should not cause a page fault.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for compatible compression for different types of image views. A graphics processor may select a first common format of a plurality of common formats for at least one image based on at least one of application data or first metadata associated with the at least one image. The graphics processor may encode the at least one image based on the selected first common format for the at least one image. The graphics processor may select a second common format for the at least one image based on second metadata of the at least one image. The second common format may be identical to the first common format. The graphics processor may decode the at least one image based on the selected second common format for the at least one image.

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: The present disclosure relates to methods and apparatus for hybrid rendering of video/graphics content by a graphics processing unit. The apparatus can configure the graphics processing unit of a display apparatus to perform multiple rendering passes for a frame of a scene to be displayed on a display device. Moreover, the apparatus can control the graphics processing unit to perform a first rendering pass of the multiple rendering passes to generate a first render target that is stored in either an on-chip graphics memory of the GPU or a system of the display apparatus. The apparatus can also control the graphics processing unit to perform a second rendering pass to generate a second render target that is alternatively stored in the system memory of the display apparatus or on-chip graphics memory of the GPU.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. An example method generally includes receiving, at a graphics processing unit (GPU), a plurality of commands corresponding to a plurality of draws across a frame, each of the plurality of commands indicating a depth test direction with respect to a low-resolution depth (LRZ) buffer for the corresponding draw. The method generally includes maintaining, at the GPU, a LRZ status buffer to store a corresponding depth test direction for a first command in time of the plurality of commands processed by the GPU. The method generally includes disabling, at the GPU, use of the LRZ buffer for depth testing for any of the plurality of commands remaining unprocessed after processing a command of the plurality of commands having a different depth test direction than the corresponding depth test direction stored in the LRZ status buffer.

Abstract: Methods, systems, and devices for rendering are described. A device may divide a frame into a plurality of bins. The device may generate a command stream containing multiple repetitions of a fixed-stride draw table (FSDT), where each repetition of the FSDT includes a respective state vector for one or more hardware registers of a set of hardware registers. The device may identify, for each bin, a subset of the multiple repetitions of the FSDT in the command stream that include a live draw call. The device may execute, using the set of hardware registers, one or more rendering commands for each bin based at least in part on the corresponding subset of the multiple repetitions of the FSDT.
