Copies/fills/updates for buffers are happening through CCU but need additional synchronization when write range is not aligned to 64 bytes. Because dst buffer access uses either R8_UNORM or R32_UINT and they are not coherent between each other in CCU since format seem to be a part of a cache key. See: https://gitlab.khronos.org/vulkan/vulkan/-/issues/3306 The synchronization with writes from UCHE (e.g. with SSBO stores) are solved by the fact that UCHE has byte level dirtiness tracking and that CCU flush would happen always before UCHE flush for such case (e.g. both renderpass and dispatch would flush pending CCU write). Additionally see: https://gitlab.khronos.org/vulkan/vulkan/-/issues/3398#note_400111 Fixes geometry corruption and potentially hangs in Resident Evil 3.

`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>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
