On MTL, instructions with DF type are unordered, executed in the math pipe. This means that they require different SWSB dependency handling, and also that in some cases such as MOVs it's generally faster to simply use 2 smaller ordered moves than a single unordered MOV. One problem we have with the current code is that generate_code() is not setting the proper SWSB dependencies for the generated DF MOVs, causing some tests to fail. One solution would be to fix generate_code() by making it set the appropriate dependencies. This was the first patch I wrote. Another solution to this problem, pointed to us by Curro, is to change required_exec_type() so we use UD instructions instead of DF, just like we do with platforms that don't have 64 bit instructions, which means there won't be anything to fix in generate_code(). The second solution is what this patch implements. This fixes at least: - dEQP-VK.subgroups.arithmetic.framebuffer.subgroupmin_double_vertex Thanks to Francisco Jerez for all the major help provided with this problem.

`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.
