  • Techniques for latching input events to display flips
    Patent number: 9823935
    Abstract: A system including one or more input interface drivers, an input dispatcher, one or more applications, a system compositor and one or more output interface drivers. The input interface driver receives input events. The input dispatcher is modified to dispatch a current input event to a corresponding application after receiving an indication that a display image based upon a previous input event has been posted to an output interface driver. The corresponding application renders a new display image based upon the current input event. The system compositor posts the new display image to the output interface driver. The system compositor is also modified to send an indication to the input dispatcher that the new display image has been posted to the output interface driver. The system iteratively performs the process to latch the dispatching of input events to the display flip.
