When u_upload_mgr fills up a buffer, it unmaps and destroys it. Our unmap function was automatically performing the equivalent of a FlushMappedBufferRange call in this case. Because the buffer mapping is persistent and coherent, we don't actually do any flushing when we do the rest of the writes to the buffer - we were just doing one final one at the end. But we would be using the uploaded contents on the GPU the whole time. This certainly shouldn't be necessary for streaming buffers, and if such flushing and dirtying is necessary for coherent buffers, this is wildly insufficient. Drops a small number of constant packets and PIPE_CONTROL flushes from most benchmarks that I've looked at. Doesn't seem to make much of an impact on performance, however. Thanks to Felix Degrood for noticing that we were emitting more 3DSTATE_CONSTANT_* packets than we needed to. |

`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.html <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.html <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.html <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.html <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses email mailing-lists for patches submission, review and discussions.
