This series adds support for DRM_MODE_PAGE_FLIP_ASYNC for atomic
commits, aka. "immediate flip" (which might result in tearing).
The feature was only available via the legacy uAPI, however for
gaming use-cases it may be desirable to enable it via the atomic
uAPI too.
- v1: https://patchwork.freedesktop.org/series/107683/
- User-space patch: https://github.com/Plagman/gamescope/pull/595
- IGT patch: https://patchwork.freedesktop.org/series/107681/
Main changes in v2: add docs, fail atomic commit if async flip isn't
possible.
Tested on an AMD Picasso iGPU.
Simon Ser (6):
amd/display: only accept async flips for fast updates
drm: document DRM_MODE_PAGE_FLIP_ASYNC
drm: introduce drm_mode_config.atomic_async_page_flip_not_supported
drm: allow DRM_MODE_PAGE_FLIP_ASYNC for atomic commits
drm: introduce DRM_CAP_ATOMIC_ASYNC_PAGE_FLIP
amd/display: indicate support for atomic async page-flips on DC

Main changes in v2: add docs, fail atomic commit if async flip isn't
possible.
Changes in v3: add a note in the documentation about Intel hardware,
add R-b tags.
Tested on an AMD Picasso iGPU (Simon) and an AMD Vangogh GPU (André).
