Currently, SurfaceFlinger is very dumb about how it handles buffer updates at less than 60fps. If there is a new frame pending, but its timestamp says not to present it until later SurfaceFlinger will wake up every vsync until it is time to present it. Even worse, if SurfaceFlinger has woken up but nothing has changed, it still goes through the entire composition process. This change (mostly) fixes that inefficiency. SurfaceFlinger will still wake up every refresh period while there is a new frame pending, but if there is no work to do, it will almost immediately go back to sleep.
