In the following sequence: - transfer_map(buffer, DISCARD) // use staging upload - memcpy(...) - transfer_unmap - draw - transfer_map(buffer, UNSYNCHRONIZED) // non-staging upload - memcpy(...) - draw Currently the order of operations is: - map#1 - staging buffer - memcpy to staging buffer - map#2 - memcpy to buffer - staging buffer copy to real buffer - draw#1 - draw#2 When the 2nd map operation doesn't use UNSYNCHRONIZED, the tc_sync_msg() call will make sure that the bo is unused before mapping it. But, if it does use UNSYNCHRONIZED and the mapped intervals overlap this commit clears the UNSYNCHRONIZED to make sure ordering is maintained. This will affect performance, but correct output is better than fast output. See https://gitlab.freedesktop.org/mesa/mesa/-/issues/3611.

`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 `Freenode's #dri-devel <irc://chat.freenode.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.
