The glsl-to-tgsi code generation and GLSL IR linker is is going away (!8044), so we need to make the call on whether to use nir-to-tgsi (See !15932 and !15541), or switch over to the NIR code generator. The NIR backend should reduce the compile time regression while providing more direct control over the IR we receive than going through NTT, while still providing the optimization that NIR-to-TGSI was bringing us. nv92 shader-db: total local in shared programs: 2048 -> 1988 (-2.93%) local in affected programs: 2048 -> 1988 (-2.93%) total gpr in shared programs: 688468 -> 724705 (5.26%) gpr in affected programs: 437159 -> 473396 (8.29%) total instructions in shared programs: 6115978 -> 5874401 (-3.95%) instructions in affected programs: 5038041 -> 4796464 (-4.80%) total loops in shared programs: 1361 -> 835 (-38.65%) loops in affected programs: 538 -> 12 (-97.77%) total bytes in shared programs: 42389752 -> 40480416 (-4.50%) bytes in affected programs: 36311616 -> 34402280 (-5.26%) LOST: 0 GAINED: 1 (pixmark-piano) nv120 shader-db: total local in shared programs: 4416 -> 1988 (-54.98%) local in affected programs: 4416 -> 1988 (-54.98%) total gpr in shared programs: 870534 -> 893490 (2.64%) gpr in affected programs: 564210 -> 587166 (4.07%) total instructions in shared programs: 6379402 -> 6243210 (-2.13%) instructions in affected programs: 5430790 -> 5294598 (-2.51%) total bytes in shared programs: 68184224 -> 66729672 (-2.13%) bytes in affected programs: 58013544 -> 56558992 (-2.51%) Acked-by: Alyssa Rosenzweig <alyssa.rosenzweig@collabora.com> Reviewed-by: Karol Herbst <kherbst@redhat.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15949> |

`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.
