In some aspects, the present disclosure provides a method for generating a frame. The method includes receiving a first fence indicating that a first frame stored in a display processor unit (DPU) buffer has been consumed by a hardware component. The method also includes in response to receiving the first fence, fetching a plurality of layers from an application buffer, the plurality of layers corresponding to a second frame. The method also includes determining to use both a DPU and a graphics processing unit (GPU) to process the plurality of layers for composition of the second frame. The method also includes fetching the first fence from the DPU buffer and generating a second fence.

The present disclosure relates to methods and apparatus for display processing. Aspects of the present disclosure can determine a refresh offset for at least one group of lines in a first display based on at least one group of lines in a second display. Aspects of the present disclosure can also apply the refresh offset for the at least one group of lines in the first display based on the at least one group of lines in the second display. Further, aspects of the present disclosure can adjust combined instantaneous bandwidth corresponding to each of the at least one group of lines in the first display and each of the at least one group of lines in the second display based on the applied refresh offset. Aspects of the present disclosure can also determine one or more overlapping layer regions based on the first display and the second display.

Methods and apparatus for refreshing multiple displays

Techniques are described for controlling the display refresh rate of a display panel. A display driver may determine a display refresh rate based on user activity. One example of user activity is a rate at which a user is scrolling image content being displayed on the display panel. One example of user activity is a duration or pressure of a user interaction with a display panel or a pressure sensor.

Dynamic control of display refresh rate based on user interface activity

Techniques are described for reducing the number of fetches performed when a background layer (e.g., letter or pillar box) to be displayed is of a constant fill color. One or more processors (e.g., a display processor) may be configured to detect that a background layer is of a constant fill color. If so, rather than fetching the background layer from memory, the one or more processors may be configured to generate the constant fill color for the background layer. In doing so, there may be a reduction in the number of memory fetches performed, as the constant fill background layer is not fetched or is only partially fetched. This may reduce memory fetch operations (as only the video layer is fetched) and therefore power savings (e.g., battery usage) at memory and bus interfaces, decreased use of the bandwidth at the bus and memory, and decreased processor usage.
