Abstract: Systems, apparatus, articles, and methods are described including operations to set an interrupt range in an interrupt register associated with a display controller. A determination may be made regarding whether a front buffer portion of a frame buffer is within the interrupt range. An interrupt may be communicated based at least in part on the determination that the front buffer portion of the frame buffer is within the interrupt range.

Abstract: Systems, apparatus, articles, and methods are described including operations to receive visible rectangle data indicating the portions of a three dimensional (3D) application being displayed. A determination of two or more scissor planes may be made based at least in part on the visible rectangle data. Two or more scissor plane registers may be set based at least in part on the determined two or more scissor planes. Image data may be rendered to a render buffer based at least in part on the determined two or more scissor planes.
