Abstract: A method for display mirroring is described. The method includes computing an updating region size for one or more application layers of a screen image, the updating region area regions of interest being updated on the screen image less any overlap between the regions of interest. The method also includes determining that the updating region size plus a previous frame size is less than a frame buffer size. The method further includes determining that there are sufficient resources available to combine the previous frame with the updating region. The method additionally includes generating a current frame by combining the previous frame and the updating region. The method also includes sending the current frame to a mirrored display.

Abstract: Optimizing compositor workload in steady state in processor devices is disclosed herein. In some aspects, a processor device is configured to perform image compositing by executing a compositor pipeline that comprises a compositor including a workload handler; a composer Hardware Abstraction Layer (HAL); a workload governor communicatively coupled to the composer HAL; and a display driver. The workload governor detects that the image compositing has entered a steady state, and transmits an indication to enter an accelerated mode to the workload handler. Upon receiving the indication, the workload handler places the compositor pipeline in the accelerated mode. While in the accelerated mode, the compositor transmits accelerated mode data directly to the display driver, bypassing the composer HAL.

Abstract: Certain aspects of the present disclosure provide a method for driving a plurality of display panels including a first display panel and a second display panel. The method includes receiving a first synchronization signal from the first display panel. The method further includes receiving a second synchronization signal from the second display panel. The method further includes determining a phase difference between the first synchronization signal and the second synchronization signal. The method further includes computing at least one phase shift offset based on the determined phase difference, the at least one phase shift offset being configured to reduce the phase difference between the first synchronization signal and the second synchronization signal. The method further includes providing a first phase shift offset of the at least one phase shift offset to the first display panel. The method further includes providing a unified synchronization signal to a display processor.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an example method may include causing a first region of a display to be refreshed without using a memory of the display, and causing a second region of the display to be refreshed using the memory of the display.

Abstract: Techniques of this disclosure may include ways to control the amount of graphics data a graphics processing unit (GPU) renders. The GPU may render graphics data for image content that changed from frame-to-frame rather than graphics data for image content that changed and did not change. To display the image content, processing circuitry may map locations of where the graphics data is stored to lines in the image content allowing for the GPU to store the graphics data in arbitrary locations of an application buffer.

Abstract: The disclosure relates to a system including a set of subsystems sharing a voltage rail. The system includes a power controller configured to send messages, such as interrupts, to the subsystems concerning a change of state of a supply voltage on the voltage rail. Such messages may have been sent in response to requests and messages from the subsystems, respectively. In response to the messages, the subsystems may send requests to the power controller for different dynamic clock voltage scaling (DCVS) levels, respectively. In response to such requests, the power controller may set the supply voltage and frequencies of clock signals for the requesting subsystems, respectively.

Abstract: A device and method of decoding video data that includes decoding the video data to generate decoded video data of a current frame of the video data, and extracting an updated regions message from the decoded video data and determining updated region location information of the current frame based on the updated regions message. An updated region of the current frame is identified based on the updated region location information, the updated region being less than a total size of the current frame, and both the identified updated region and decoded video data of the current frame that has not been updated are transmitted for display of the current frame of the video data.
