To solve that, this patchset creates a new drm_plane field, bool async_flip, that allows drivers to choose which plane can or cannot do async flips. This is latter used on drm_atomic_set_property when users want to do async flips. Patch 1 allows async commits with IN_FENCE_ID in any driver. Patches 2 to 7 have no function change. As per current code, every driver that allows async page flips using the atomic API, allows doing it only in the primary plane. Those patches then enable it for every driver. Patch 8 finally enables async flip on overlay planes for amdgpu. Changes from v5: - Instead of enabling plane->async_flip in the common code, move it to driver code. - Enable primary plane async flip on every driver https://lore.kernel.org/dri-devel/20240612193713.167448-1-andrealmeid@igalia.com/ André Almeida (8): drm/atomic: Allow userspace to use explicit sync with atomic async flips drm: Support per-plane async flip configuration drm/amdgpu: Enable async flips on the primary plane drm: atmel-hlcdc: Enable async flips on the primary plane drm/i915: Enable async flips on the primary plane drm/nouveau: Enable async flips on the primary plane drm/vc4: Enable async flips on the primary plane drm/amdgpu: Make it possible to async flip overlay planes drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_plane.c | 2 ++ drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c | 3 +++ drivers/gpu/drm/drm_atomic_uapi.c | 8 +++++--- drivers/gpu/drm/i915/display/i9xx_plane.c | 3 +++ drivers/gpu/drm/nouveau/dispnv04/crtc.c | 4 ++++ drivers/gpu/drm/nouveau/dispnv50/wndw.c | 4 ++++ drivers/gpu/drm/vc4/vc4_plane.c | 4 +++- include/drm/drm_plane.h | 5 +++++ 8 files changed, 29 insertions(+), 4 deletions(-)
