Abstract
A processor includes a scheduler that governs which of a plurality of pending graphics contexts is selected for execution at a graphics pipeline of the processor. The processor also includes a plurality of flip queues storing data ready to be rendered at a display device. The executing graphics context can issue a flip request to change data at stored at one of the flip queues. In response to determining that the flip request targets a flip queue that is being used for rendering at the display device, the scheduler executes a context switch to schedule a different graphics context for execution at the graphics pipeline.
