In Aztec Ruins, we end up storing some big shared-mem arrays as 16-bit, cutting shared mem size in half across many shaders while also reducing conversions. gfxbench vk-5-normal perf +0.364983% +/- 0.189764% (n=4). fossil-db: Totals from 448 (2.99% of 14988) affected shaders: MaxWaves: 6154 -> 6390 (+3.83%); split: +3.96%, -0.13% Instrs: 174554 -> 165045 (-5.45%); split: -6.45%, +1.01% CodeSize: 364224 -> 345558 (-5.12%); split: -6.03%, +0.90% NOPs: 48224 -> 48024 (-0.41%); split: -3.33%, +2.91% MOVs: 6985 -> 6104 (-12.61%); split: -19.11%, +6.50% Full: 4577 -> 4101 (-10.40%); split: -11.08%, +0.68% (ss): 3428 -> 3335 (-2.71%); split: -4.17%, +1.46% (sy): 1250 -> 1205 (-3.60%); split: -4.72%, +1.12% (ss)-stall: 14695 -> 14528 (-1.14%); split: -2.25%, +1.12% (sy)-stall: 19565 -> 17998 (-8.01%); split: -9.55%, +1.54% STPs: 1086 -> 870 (-19.89%) LDPs: 162 -> 108 (-33.33%) Cat0: 51400 -> 51120 (-0.54%); split: -3.31%, +2.76% Cat1: 16861 -> 14688 (-12.89%); split: -18.18%, +5.30% Cat2: 71161 -> 68454 (-3.80%); split: -4.52%, +0.72% Cat3: 29572 -> 25306 (-14.43%); split: -14.49%, +0.06% Cat4: 3128 -> 3131 (+0.10%) Cat5: 1502 -> 1506 (+0.27%) Cat6: 840 -> 750 (-10.71%) aztec ruins is a big winner with the ldp/stp reductions. summoners_war racks up an astounding 41% reduction in instructions and +15% max_waves. Most affected apps show a minor win in instrs, with fallout_shelter_online, and aztec ruins on ANGLE taking minor hits. Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/18259> |

`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 `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://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.
