Subject: [RFC v3 0/8] drm/atomic: add async plane update
Date: Fri, 12 May 2017 16:10:46 -0300 [thread overview]
Message-ID: <20170512191054.10074-1-gustavo@padovan.org> (raw)
From: Gustavo Padovan <gustavo.padovan@collabora.com>
Hi,
One more take of Asynchronous Plane Updates over Atomic. Here I looked
to msm, vc4 and i915 to identify a common pattern to create atomic helpers
for async updates. So in patch 1 drm_atomic_async_check() and
drm_atomic_helper_async_commit() are introduced along with driver's plane hooks:
->atomic_async_check() and ->atomic_async_commit().
For now we only support async update for one plane at a time. Also the async
update can't modify the CRTC so no modesets are allowed.
Then the other patches add support for it in the drivers. I did virtio mostly
for testing. msm and vc4 are only compile-tested.
I started IGT changes to test the Atomic IOCTL with the new flag:
https://git.collabora.com/cgit/user/padovan/intel-gpu-tools.git/
Support for async page flips and drm core workers to delay plane/fb clean up
are not plane for this patchset.
TODO
* improve i-g-t tests where needed
Gustavo Padovan (8):
drm/atomic: initial support for asynchronous plane update
drm/virtio: support async cursor updates
drm/i915: update cursors asynchronously through atomic
drm/i915: remove intel_cursor_plane_funcs
drm/msm: update cursors asynchronously through atomic
drm/msm: remove mdp5_cursor_plane_funcs
drm/vc4: update cursors asynchronously through atomic
drm/atomic: add ASYNC_UPDATE flag to the Atomic IOCTL
