This will let us share a common scratch swizzling between brw and jay. Changes by Ken: - Use an immediate SIMD width when known so we don't need to re-lower - Switch to load_simd_width_intel because it may not match info->api_subgroup_size on Vulkan without VK_EXT_subgroup_size_control - Stop using DWord Scattered Write messages for scratch. These take an offset in DWords, and our offsets are now always in bytes. This also means that we no longer create MEMORY_OPCODE_* IR with inconsistent units of either bytes or dwords. Yikes. We use byte scattered messages now. fossil-db stats on Battlemage: Instrs: 500477504 -> 500450056 (-0.01%); split: -0.01%, +0.00% CodeSize: 7807432368 -> 7806786192 (-0.01%); split: -0.01%, +0.00% Cycle count: 62404008370 -> 62398437734 (-0.01%); split: -0.01%, +0.00% Fill count: 546690 -> 546695 (+0.00%); split: -0.00%, +0.00% Max live registers: 141257956 -> 141258100 (+0.00%); split: -0.00%, +0.00% Non SSA regs after NIR: 72350283 -> 72336544 (-0.02%) Totals from 99 (0.01% of 1581969) affected shaders: Instrs: 366593 -> 339145 (-7.49%); split: -7.58%, +0.09% CodeSize: 6425936 -> 5779760 (-10.06%); split: -10.06%, +0.00% Cycle count: 2412009876 -> 2406439240 (-0.23%); split: -0.26%, +0.03% Fill count: 19675 -> 19680 (+0.03%); split: -0.02%, +0.04% Max live registers: 17600 -> 17744 (+0.82%); split: -0.09%, +0.91% Non SSA regs after NIR: 37894 -> 24155 (-36.26%) Signed-off-by: Alyssa Rosenzweig <alyssa.rosenzweig@intel.com> Signed-off-by: Kenneth Graunke <kenneth@whitecape.org> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/40843> |

`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.
