Abstract
Aspects presented herein relate to methods and devices for display processing including an apparatus, e.g., a CPU. The apparatus may perform a partial frame update for a first frame at a first update time, where the partial frame update corresponds to an update of less than all content in the first frame, where the partial frame update for the first frame is associated with a panel ROI of the first frame. The apparatus may also calculate a margin time period between the first update time and a subsequent Vsync time. Further, the apparatus may transmit, based on the margin time period, a first indication of a subsequent frame transfer interrupt time. The apparatus may also transmit, to a DPU, a second indication to transfer the set of second frames at a reduced DPU clock frequency and a reduced bandwidth frequency starting at the subsequent frame transfer interrupt time.
