According to HSD 1407682962 and the associated simulator code, fast-clear performance can be affected by: image alignment, tiling, dimensionality, and row pitch. Redescribe surfaces in order avoid fast-clearing at a slower rate. Also, benchmarking the main patch in the performance CI (hw=A750) shows that some traces are helped significantly: * TotalWarWarhammer3 +5.58% (n=2) * Factorio +3.75% (n=1) * TerminatorResistance +3.3% (n=2) * Borderlands3 +3.23% (n=2) We could additionally increase the alignment requirements of surfaces in order to deterministically increase fast-clear performance. That's left out of this patch in order to avoid any functional pitfalls that can arise with increased memory consumption. As a result, performance will continue to be affected by how ISL/drivers/apps configure main surface memory alignments (directly or indirectly). Thanks to Lionel Landwerlin for pointing me to the relevant simulator code.

`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.
