    Abstract: The present disclosure relates to graphics processing. An apparatus of the present disclosure may determine visibility streams corresponding to a target and a set of bins into which the target is divided. The apparatus may select one of a first rendering mode or a second rendering mode for the target based on the first visibility stream and based on the set of second visibility streams. When the first rendering mode is select, the apparatus may configure each of the set of bins into a first subset associated with a first type of rendering pass or a second subset associated with a second type of rendering pass. The apparatus may then render the target based on the selected one of the first rendering mode or the second rendering mode and, if applicable, based on the first rendering pass type or the second rendering pass type.

  • 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.
