[PATCH v4 0/3] drm/atomic: Allow drivers to write their own plane check for async

From: André Almeida
Date: Thu Feb 08 2024 - 16:06:22 EST


AMD hardware can do async flips with overlay planes, so this patchset does a
small redesign to allow drivers to choose per plane type if they can or cannot
do async flips.

It also allows async commits with IN_FENCE_ID in any driver.

drm: Allow drivers to choose plane types to async flip
drm/amdgpu: Make it possible to async flip overlay planes
