If there is holes, eg. if only MRT0 and MRT2 are exported, we have to set MRT1 to SPI_SHADER_32_R to avoid a GPU hang but the export can still be removed from the fragment shader. fossils-db (Sienna Cichlid): Totals from 565 (0.42% of 134913) affected shaders: VGPRs: 13328 -> 11456 (-14.05%) CodeSize: 613232 -> 548224 (-10.60%); split: -11.13%, +0.53% LDS: 284672 -> 296960 (+4.32%) MaxWaves: 17624 -> 17684 (+0.34%) Instrs: 113056 -> 100445 (-11.15%); split: -11.68%, +0.53% Latency: 684327 -> 639348 (-6.57%); split: -7.17%, +0.60% InvThroughput: 122877 -> 104382 (-15.05%); split: -15.18%, +0.13% VClause: 2601 -> 2323 (-10.69%); split: -10.77%, +0.08% SClause: 5629 -> 5443 (-3.30%); split: -3.91%, +0.60% Copies: 9393 -> 8720 (-7.16%); split: -8.22%, +1.05% PreSGPRs: 14623 -> 13666 (-6.54%); split: -6.76%, +0.22% PreVGPRs: 9847 -> 8503 (-13.65%) fossils-db (Polaris10): Totals from 565 (0.42% of 135960) affected shaders: SGPRs: 28064 -> 27104 (-3.42%) VGPRs: 12516 -> 10544 (-15.76%); split: -15.79%, +0.03% CodeSize: 516920 -> 456536 (-11.68%); split: -11.68%, +0.00% MaxWaves: 4369 -> 4418 (+1.12%) Instrs: 97771 -> 85903 (-12.14%); split: -12.14%, +0.00% Latency: 767482 -> 708545 (-7.68%); split: -7.97%, +0.29% InvThroughput: 280017 -> 235744 (-15.81%) VClause: 2270 -> 2090 (-7.93%); split: -8.50%, +0.57% SClause: 5185 -> 5012 (-3.34%); split: -3.86%, +0.52% Copies: 8328 -> 7555 (-9.28%); split: -9.35%, +0.07% Branches: 1143 -> 1113 (-2.62%) PreSGPRs: 13816 -> 12725 (-7.90%); split: -7.92%, +0.02% PreVGPRs: 9707 -> 8270 (-14.80%) Signed-off-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Reviewed-by: Rhys Perry <pendingchaos02@gmail.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15108>
`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>`_).
