Memory accesses need to be aligned up to the next power of two of the full access size. Component count and bit-size don't matter to the hardware, only the total size. shader-db results are pretty much what you would expect, there are a few shaders that have increased LS instructions as a result of splitting accesses to satisfy alignment requirements that were previously ignored. The one surprising thing is that there are several shaders that have reduced uniform usage. Looking at some of these individually, what happened is that splitting UBO loads early allowed the compiler to eliminate loads from unused ranges of the access. total instrs in shared programs: 719166 -> 719174 (<.01%) instrs in affected programs: 2355 -> 2363 (0.34%) helped: 4 HURT: 6 helped stats (abs) min: 1.0 max: 9.0 x̄: 3.00 x̃: 1 helped stats (rel) min: 0.36% max: 6.52% x̄: 1.99% x̃: 0.54% HURT stats (abs) min: 1.0 max: 4.0 x̄: 3.33 x̃: 4 HURT stats (rel) min: 0.65% max: 2.13% x̄: 1.38% x̃: 1.48% 95% mean confidence interval for instrs value: -2.14 3.74 95% mean confidence interval for instrs %-change: -1.76% 1.82% Inconclusive result (value mean confidence interval includes 0). total cycles in shared programs: 30210.83 -> 30218.81 (0.03%) cycles in affected programs: 50 -> 57.99 (15.97%) helped: 2 HURT: 6 helped stats (abs) min: 0.0078129999999999589 max: 0.070312000000000041 x̄: 0.04 x̃: 0 helped stats (rel) min: 1.10% max: 10.23% x̄: 5.66% x̃: 5.66% HURT stats (abs) min: 0.03125 max: 5.0 x̄: 1.34 x̃: 1 HURT stats (rel) min: 2.38% max: 25.00% x̄: 13.05% x̃: 14.26% 95% mean confidence interval for cycles value: -0.42 2.41 95% mean confidence interval for cycles %-change: -1.74% 18.49% Inconclusive result (value mean confidence interval includes 0). total cvt in shared programs: 2385.91 -> 2385.91 (<.01%) cvt in affected programs: 11.14 -> 11.14 (<.01%) helped: 5 HURT: 4 helped stats (abs) min: 0.0078119999999999301 max: 0.070312000000000041 x̄: 0.02 x̃: 0 helped stats (rel) min: 0.27% max: 10.23% x̄: 2.61% x̃: 0.82% HURT stats (abs) min: 0.01562600000000014 max: 0.03125 x̄: 0.03 x̃: 0 HURT stats (rel) min: 1.31% max: 2.75% x̄: 2.21% x̃: 2.40% 95% mean confidence interval for cvt value: -0.02 0.02 95% mean confidence interval for cvt %-change: -3.51% 2.58% Inconclusive result (value mean confidence interval includes 0). total ls in shared programs: 25871 -> 25879 (0.03%) ls in affected programs: 46 -> 54 (17.39%) helped: 0 HURT: 4 HURT stats (abs) min: 1.0 max: 5.0 x̄: 2.00 x̃: 1 HURT stats (rel) min: 10.00% max: 25.00% x̄: 18.38% x̃: 19.26% 95% mean confidence interval for ls value: -1.18 5.18 95% mean confidence interval for ls %-change: 8.46% 28.30% Inconclusive result (value mean confidence interval includes 0). total code size in shared programs: 6302848 -> 6302976 (<.01%) code size in affected programs: 1536 -> 1664 (8.33%) helped: 0 HURT: 1 total registers used in shared programs: 117324 -> 117329 (<.01%) registers used in affected programs: 45 -> 50 (11.11%) helped: 1 HURT: 2 helped stats (abs) min: 1.0 max: 1.0 x̄: 1.00 x̃: 1 helped stats (rel) min: 6.25% max: 6.25% x̄: 6.25% x̃: 6.25% HURT stats (abs) min: 2.0 max: 4.0 x̄: 3.00 x̃: 3 HURT stats (rel) min: 12.50% max: 30.77% x̄: 21.63% x̃: 21.63% total uniforms used in shared programs: 78538 -> 78274 (-0.34%) uniforms used in affected programs: 2688 -> 2424 (-9.82%) helped: 104 HURT: 4 helped stats (abs) min: 1.0 max: 18.0 x̄: 2.65 x̃: 2 helped stats (rel) min: 1.96% max: 54.55% x̄: 12.78% x̃: 11.11% HURT stats (abs) min: 1.0 max: 5.0 x̄: 3.00 x̃: 3 HURT stats (rel) min: 3.70% max: 16.13% x̄: 9.92% x̃: 9.92% 95% mean confidence interval for uniforms used value: -3.01 -1.88 95% mean confidence interval for uniforms used %-change: -14.15% -9.74% Uniforms used are helped.

`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://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ 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://docs.mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
