This bumps the supported dma-buf version up to 4 and adds the initial dma-buf feedback implementation. It follows the changes in the dma-buf protocol extension [1] to include the dma-buf feedback interface, which should be incorporated by most Wayland compositors in the future. From version 4 onwards, the dma-buf modifier events are not sent by the compositor anymore, so we use the default feedback to pick the set of formats/modifiers supported by the compositor. Also, we try to avoid the wl_drm device event and instead use the dma-buf feedback main device. We only fallback to wl_drm when the compositor advertises a device that does not have a render node associated. In this initial dma-buf feedback implementation we still don't do anything with the per-surface dma-buf feedback, but in the next commits we add proper support. It's important to mention that this also bumps the minimal supported version of wayland-protocols to 1.24, in order to include [1].

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://mesa3d.org/bugs.html>`_).
