Mesa 3D graphics library
fcd025c1ce
The current name doesn't cover all the tex related instructions and in all usages, we already have a switch statement to dispatch per instruction type, so is more natural to list the instructions we care there. In fs::is_send_from_grf() we can simply ignore them since the instructions are either lowered directly to SEND (Gfx7+) or use MRF (Gfx6-). With this change, the fs_inst::size_read() generated code gets simplified (the "tex" entries get added to the switch jump table in gcc) and the default case loses the conditional handling tex. This reduces shader compilation time, as illustrated by replaying fossils (tested on my TGL laptop): ``` // Rise of the Tomb Raider (N=13) Difference at 95.0% confidence -1.32231 +/- 0.0170138 -4.37605% +/- 0.0563054% (Student's t, pooled s = 0.0210159) // Cyberpunk 2077 (N=7) Difference at 95.0% confidence -3.64 +/- 0.114993 -2.95188% +/- 0.0932544% (Student's t, pooled s = 0.09873) ``` Suggested-by: Kenneth Graunke <kenneth@whitecape.org> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/25721> |

`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.
