[v2,0/6] Asynchronous flip implementation for i915

Message

Karthik B S April 20, 2020, 9:47 a.m. UTC

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.

v2: Few patches have been squashed and patches have been shuffled as
    per the reviews on the previous version.

Karthik B S (6):
  drm/i915: Add enable/disable flip done and flip done handler
  drm/i915: Add support for async flips in I915
  drm/i915: Enable 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: Do not call drm_crtc_arm_vblank_event in async flips
