[PATCH 0/4] Add support for atomic async page-flips

[Simon Ser]

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.

User-space patch:

Tested on an AMD Picasso iGPU.

Simon Ser (4):
  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 DCN
