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.



I tested on an AMD vangogh GPU and worked with the IGT tests.

[ANNOUNCE] weston 11.0.0

[Simon Ser]

This is the official release for Weston 11.0.0.

Highlights for this release:

- Continued work on color management infrastructure: 
  In Weston 11, if you enable the tentative, experimental and WIP color
  management option, Weston will not only blend in linear light, but
  you can also set up a monitor ICC profile and Weston will do some
  kind of color mapping from sRGB to that profile. Furthermore, you can
  configure a monitor into HDR mode and deliver HDR characteristics from
  weston.ini to the monitor, but Weston will *not* produce proper HDR
  content yet, meaning the display is incorrect.
- Various RDP improvements.
- Performance improvements in the DRM backend.
- Support for the wp_single_pixel_buffer_v1 protocol.
- weston_buffer refactoring.
- Groundwork for running multiple backends at the same time (e.g. KMS + RDP)
  and for multi-GPU support in the DRM backend. This is not supported
  yet, but may be in a future release.

Breaking changes for users:

- The cms-static and cms-colord plugins are now deprecated.
- A number of features have been removed from desktop-shell: multiple
  workspaces, zoom, exposay.
- wl_shell support has been removed (superseded by xdg-shell).
- The fbdev backend has been removed (superseded by KMS).
- weston-launch and launcher-direct have been removed (superseded by libseat).
- The weston-info and weston-gears clients have been removed (weston-info is
  superseded by wayland-info).
- The KMS max-bpc property is now set by default. If you experience black
  screens with (faulty) monitors, try lowering it in weston.ini.
- Weston will now abort when running out of memory. Weston is not suitable
  for memory constrained environments.
