Unfortunately we have to disable concurrent binning by default because it hurts performance in a number of desktop games without any case where we know it helps. There are less vertex fetch resource available in BV compared to BR, so when binning runs in BV, there are many vertices, and vertices are attribute heavy - BV has much worse performance than BR, sometimes more than 50% worse. Even with worse performance it won't be bad if concurrent binning actually overlapped with other workload in those cases, but in case of desktop games - there is almost never a chance for overlap. However it's impossible to statically find out if binning on BV would be much slower than on BR, and we also cannot statically predict if there is enough overlap (if any) to cover for the performance penalty. Given the above, I don't see a way out but to make concurrent binning opt in via `tu_allow_concurrent_binning` driconf toggle. Still allow concurrent binning in CI to catch issues early.

`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://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ 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://docs.mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
