We now have NIR opt_large_constants support in place, so we can flip the switch and get better optimization before lowering to a constant buffer, but also avoid having constant data mixed in with the shader's uniforms, which should lower CPU overhead on affected shaders. Only a few shaders are affected (<.01% impact across shader-db), but for those the impact is pretty big: instructions in affected programs: 748 -> 639 (-14.57%) nops in affected programs: 364 -> 284 (-21.98%) non-nops in affected programs: 384 -> 355 (-7.55%) mov in affected programs: 47 -> 27 (-42.55%) cov in affected programs: 9 -> 6 (-33.33%) dwords in affected programs: 932 -> 836 (-10.30%) full in affected programs: 13 -> 14 (7.69%) constlen in affected programs: 140 -> 64 (-54.29%) (ss) in affected programs: 14 -> 15 (7.14%) Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/5810> |

`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.
