Now that register spilling is in place, this is reasonable. It turns out for some shaders, it's actually better to cap at 8 work registers and extra >8 uniform reigsters and tolerate the spilling, since the extra resulting threads make up for the spillage. So incidentally, the shader that spills here is in -bterrain, which jumps from 19fps to 21fps as a result of this change. total instructions in shared programs: 3513 -> 3448 (-1.85%) instructions in affected programs: 776 -> 711 (-8.38%) helped: 20 HURT: 0 helped stats (abs) min: 1 max: 8 x̄: 3.25 x̃: 2 helped stats (rel) min: 3.57% max: 16.00% x̄: 8.37% x̃: 7.19% 95% mean confidence interval for instructions value: -4.28 -2.22 95% mean confidence interval for instructions %-change: -10.02% -6.73% Instructions are helped. total bundles in shared programs: 2067 -> 2024 (-2.08%) bundles in affected programs: 515 -> 472 (-8.35%) helped: 19 HURT: 1 helped stats (abs) min: 1 max: 6 x̄: 2.37 x̃: 2 helped stats (rel) min: 2.13% max: 17.86% x̄: 10.19% x̃: 11.11% HURT stats (abs) min: 2 max: 2 x̄: 2.00 x̃: 2 HURT stats (rel) min: 3.23% max: 3.23% x̄: 3.23% x̃: 3.23% 95% mean confidence interval for bundles value: -3.01 -1.29 95% mean confidence interval for bundles %-change: -12.13% -6.91% Bundles are helped. total quadwords in shared programs: 3468 -> 3426 (-1.21%) quadwords in affected programs: 764 -> 722 (-5.50%) helped: 19 HURT: 1 helped stats (abs) min: 1 max: 5 x̄: 2.26 x̃: 2 helped stats (rel) min: 1.41% max: 12.50% x̄: 6.76% x̃: 7.14% HURT stats (abs) min: 1 max: 1 x̄: 1.00 x̃: 1 HURT stats (rel) min: 1.08% max: 1.08% x̄: 1.08% x̃: 1.08% 95% mean confidence interval for quadwords value: -2.83 -1.37 95% mean confidence interval for quadwords %-change: -8.08% -4.65% Quadwords are helped. total registers in shared programs: 383 -> 360 (-6.01%) registers in affected programs: 112 -> 89 (-20.54%) helped: 19 HURT: 0 helped stats (abs) min: 1 max: 3 x̄: 1.21 x̃: 1 helped stats (rel) min: 12.50% max: 27.27% x̄: 20.63% x̃: 20.00% 95% mean confidence interval for registers value: -1.47 -0.95 95% mean confidence interval for registers %-change: -22.39% -18.87% Registers are helped. total threads in shared programs: 432 -> 451 (4.40%) threads in affected programs: 19 -> 38 (100.00%) helped: 11 HURT: 0 helped stats (abs) min: 1 max: 2 x̄: 1.73 x̃: 2 helped stats (rel) min: 100.00% max: 100.00% x̄: 100.00% x̃: 100.00% 95% mean confidence interval for threads value: 1.41 2.04 95% mean confidence interval for threads %-change: 100.00% 100.00% Threads are [helped]. total loops in shared programs: 4 -> 4 (0.00%) loops in affected programs: 0 -> 0 helped: 0 HURT: 0 total spills in shared programs: 0 -> 4 spills in affected programs: 0 -> 4 helped: 0 HURT: 2 total fills in shared programs: 0 -> 7 fills in affected programs: 0 -> 7 helped: 0 HURT: 2 Signed-off-by: Alyssa Rosenzweig <alyssa.rosenzweig@collabora.com> |

`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.html <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.html <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 `Freenode's #dri-devel <irc://chat.freenode.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.html <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.html <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses email mailing-lists for patches submission, review and discussions.
