[PATCH 0/5] drm/amdgpu: Page flip improvement and related cleanups

[Michel Dänzer]

The main purpose of this series is patch 5, which can avoid delaying
flips for a frame in some cases. It depends on patch 4 to prevent flips
from taking effect too early, which in turn depends on the core DRM
patch 2.

Patches 1 & 3 are cleanups I noticed while working on the other patches.

Mario, it would be great if you could run these through your rigorous
vblank testing.

[PATCH 1/5] drm: Only handle _DRM_VBLANK_NEXTONMISS once
[PATCH 2/5] drm: Keep track of last vblank sequence waited for
[PATCH 3/5] drm/amdgpu: Unpin BO if we can't get fences in
[PATCH 4/5] drm/amdgpu: Wait for end of last waited-for vblank before
[PATCH 5/5] drm/amdgpu: Set MASTER_UPDATE_MODE to 0 again
