By the time this runs, we will have already lowered load_ubo and load_vbo to load_constant_agx so we need to handle the backend version. This is very important for reducing register pressure in monolithic VS+GS shaders on AGX. Since no other backend has _agx intrinsics, there's no need for an option to gate this. The additional instruction count is from more frequent wait instructions due to fewer instructions grouped together. This should be mitigated in the future with an ACO-style latency-reducing scheduler in the backend, after register pressure is reduced by opt_sink. total instructions in shared programs: 1793385 -> 1796101 (0.15%) instructions in affected programs: 199816 -> 202532 (1.36%) helped: 3 HURT: 941 Instructions are HURT. total bytes in shared programs: 11799628 -> 11805004 (0.05%) bytes in affected programs: 1345656 -> 1351032 (0.40%) helped: 34 HURT: 919 Bytes are HURT. total halfregs in shared programs: 533151 -> 525818 (-1.38%) halfregs in affected programs: 40335 -> 33002 (-18.18%) helped: 613 HURT: 42 Halfregs are helped. total threads in shared programs: 18910464 -> 18916608 (0.03%) threads in affected programs: 6144 -> 12288 (100.00%) helped: 12 HURT: 0 Threads 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://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.
