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: https://github.com/Plagman/gamescope/pull/595 IGT patch: https://patchwork.freedesktop.org/series/107681/ Tested on an AMD Picasso iGPU.
