For MTL (verx10 == 125), float64 is supported, but int64 is not. Therefore we need to lower cluster broadcast using 32-bit int ops. For gfx12.5+ platforms that support int64, the register regions used by cluster broadcast aren't supported by the 64-bit pipeline. On MTL, dEQP-VK.subgroups.clustered.*_double* and dEQP-VK.subgroups.clustered.*_dvec* were failing to validate the compiled shader in debug mode, and reportedly gpu-hanging in release mode. With this change dEQP-VK.subgroups.clustered.*_double* passed all 48 tests and dEQP-VK.subgroups.clustered.*_dvec* passed all 140 tests on MTL. Rework: * Move from generator to brw_fs_lower_regioning.cpp. (Suggested by Francisco) * Apply to verx10 >= 125..

`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.
