Without async flip support in the kernel, fullscreen apps where game
resolution is equal to the screen resolution, must perform an extra blit
per frame prior to flipping.
Asynchronous page flips will also boost the FPS of Mesa benchmarks.
Karthik B S (7):
drm/i915: Define flip done functions and enable IER
drm/i915: Add support for async flips in I915
drm/i915: Make commit call blocking in case of async flips
drm/i915: Add checks specific to async flips
drm/i915: Add flip_done_handler definition
drm/i915: Enable and handle flip done interrupt
drm/i915: Do not call drm_crtc_arm_vblank_event in async flips
