The VBO module maps a buffer with GL_MAP_FLUSH_EXPLICIT, and keeps appending data, and calling glFlushMappedBufferRange(). We were invalidating the VF cache each time it flushed a new range, which results in a ton of VF flushes. If the contents of the destination in the target range are undefined (never even possibly written), this patch makes us assume that it's likely not in the cache and so cache invalidations are required. If the destination range is defined, we continue cache flushing as we may need to expunge stale data. This eliminates 88% of the VF cache invalidates on Manhattan 3.0. Improves performance in Manhattan 3.0 on my Icelake 8x8 with the GPU frequency locked to 700Mhz by 0.376724% +/- 0.0989183% (n=10). |

`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>`_).
