The core pass can do our at_sample lowering, while also optimizing it and at_offset. This leaves just load_sample_pos lowering in our pass, which will be renamed in the next commit. However, the prior load_sample_pos lowering needed to be split between load_sample_pos and load_sample_pos_from_id, because the new at_sample lowering generates load_sample_pos_from_id directly. shader-db effect (Batman: Arkham Origins, Fallout4, GTAV, Metro Exodus, Sherlock): Totals from 150 (0.01% of 1560788) affected shaders: MaxWaves: 1346 -> 1586 (+17.83%); split: +17.83%, -7.73% Instrs: 31464 -> 30311 (-3.66%); split: -4.52%, +0.57% CodeSize: 61962 -> 68216 (+10.09%); split: -1.05%, +12.94% NOPs: 4598 -> 4556 (-0.91%); split: -10.46%, +10.24% MOVs: 479 -> 523 (+9.19%); split: -17.12%, +32.36% COVs: 180 -> 171 (-5.00%) Full: 1300 -> 1067 (-17.92%) (ss): 880 -> 842 (-4.32%); split: -15.80%, +10.91% (sy): 510 -> 562 (+10.20%); split: -5.10%, +19.22% (ss)-stall: 3112 -> 2930 (-5.85%); split: -21.30%, +19.06% (sy)-stall: 13774 -> 12429 (-9.76%); split: -16.06%, +5.10% Preamble Instrs: 6814 -> 12145 (+78.24%) Early Preamble: 75 -> 13 (-82.67%) Cat0: 4971 -> 4929 (-0.84%); split: -9.68%, +9.47% Cat1: 650 -> 677 (+4.15%); split: -15.23%, +23.85% Cat2: 15246 -> 15210 (-0.24%); split: -0.34%, +0.10% Cat3: 9661 -> 9595 (-0.68%) Cat4: 2382 -> 2358 (-1.01%) Cat5: 2209 -> 1672 (-24.31%) Cat7: 1075 -> 600 (-44.19%) Subgroup size: 17600 -> 18880 (+7.27%) Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/38911> |

`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.
