It's not exactly 128 because longer loop bodies scale the number down. This improves perf for VP13/Creo and Piano. Most other tests either didn't show any difference or are CPU-bound. v2: - The lowering passes had to be moved to the optimization loop because unrolling creates lowerable variables. - Piano has some pattern that looks like corruption and the pattern changed with loop unrolling. The pattern is present on other drivers as well. v3: - I removed the Piano test from CI traces because the image is random. The output was wrong even before this MR, and now it's randomly wrong. | PERCENTAGE DELTAS | Shaders | SGPRs | VGPRs |SpillSGPR |SpillVGPR | PrivVGPR | Scratch | CodeSize | MaxWaves | |------------------------|----------|----------|----------|----------|----------|----------|----------|----------|----------| | alien_isolation | 2936| . | 0.02 %| . | . | . | . | 0.83 %| . | | deadcore | 76| 18.47 %| . | . | . | . | . | 167.69 %| . | | deus_ex_mankind_div.. | 1410| 0.10 %| 0.15 %| . | . | . | . | 1.70 %| . | | f1-2015 | 775| 0.37 %| 0.16 %| . | . | . | . | 3.25 %| -0.07 %| | hitman | 1413| 0.10 %| -0.03 %| 6.45 %| . | . | . | 0.61 %| 0.03 %| | metro_2033_redux | 2670| . | . | . | . | . | . | 0.13 %| 0.01 %| | pixmark-piano-0.7.0 | 2| . | 14.29 %| -100.00 %| . | . | . | 78.07 %| -4.76 %| | reflections_subway | 98| -0.53 %| . | . | . | . | . | 7.64 %| . | | thea | 172| 0.12 %| -0.81 %| . | . | . | . | 0.65 %| 0.15 %| | ubershaders | 54| . | . | . | . | . | . | 61.13 %| . | | ue4_effects_cave | 290| 0.05 %| . | . | . | . | . | 2.62 %| . | | vp13-creo | 26| -3.38 %| -4.20 %| . | . | . | . | 88.56 %| 2.62 %| | vp13-sw | 100| -0.36 %| -9.14 %| . | -100.00 %| . | -100.00 %| -17.97 %| 0.39 %| | vp20-creo | 22| -0.82 %| -3.33 %| . | . | . | . | 81.59 %| 1.51 %| | vp20-sw | 296| -4.51 %| -0.63 %| . | . | . | . | 58.93 %| 0.20 %| |------------------------|----------|----------|----------|----------|----------|----------|----------|----------|----------| | All affected | 189| 3.05 %| -2.87 %| 500.00 %| -100.00 %| . | -100.00 %| 135.61 %| 1.32 %| |------------------------|----------|----------|----------|----------|----------|----------|----------|----------|----------| | Total | 57794| 0.01 %| -0.02 %| 0.27 %| -3.13 %| . | -2.89 %| 1.73 %| . | Reviewed-by: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com> (v1) Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/13966> |

`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.
