  • Publication number: 20230019763
    Abstract: The present disclosure relates to methods and apparatus for graphics processing. For example, disclosed techniques facilitate improving bindless state processing at a graphics processor. Aspects of the present disclosure can receive, at a graphics processor, a shader program including a preamble section and a main instructions section. Aspects of the present disclosure can also execute, with a scalar processor dedicated to processing preamble sections, instructions of the preamble section to implement a bindless mechanism for loading constant data associated with the shader program. Additionally, aspects of the present disclosure can distribute the main instructions section and the constant data to a streaming processor for executing the shader program.

  • Patent number: 11373268
    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.

  • Patent number: 11321804
    Abstract: Methods, systems, and devices for graphics processer unit (GPU) operations are described. A device may monitor one or more states of a GPU during a duration. Based on monitoring the one or more GPU states, the device may determine an execution of a GPU command that is common to at least two GPU operations for clearing the GPU buffer. The device may determine whether the GPU clear command has previously been executed during a duration or a GPU cycle in which the device monitored the GPU states. The device may process the GPU clear command based on the determination of whether the GPU clear command has previously been executed. For example, the device may drop the GPU clear command based on the determination or modify a portion of the GPU clear command and execute at least the modified portion of the GPU clear command.

  • Patent number: 11176734
    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.

  • Publication number: 20200013137
    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.

  • Patent number: 10157443
    Abstract: The techniques of this disclosure include deferred batching of incremental constant loads. Graphics APIs include the ability to use lightweight constants for use by shaders. A buffer is allocated by a graphics processing unit (GPU) driver that contains a snapshot of the current lightweight constants. This may provide a complete set of state to serve as a starting point. From then on updates to the lightweight constants may be appended to this buffer in an incremental fashion by inserting the update and increasing the size of the buffer by a command processor on a graphics processing unit (GPU). The incremental nature of the updates may be captured, but removes the need for issuing them on every draw call and instead the incremental updates may be batch processed when a live draw call is encountered.

  • Patent number: 9489313
    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.
