This adds 4 NIR intrinsics for attribute I/O which match the Turing hardware instructions as well as a lowering pass to lower load/store[_per_vertex]_input/output to thewe intrinsics. This greatly simplifies nak_to_nir.rs. Also, this pass is able to handle a bunch of cases that the current code in nak_from_nir.rs can't: - Misaligned access (i.e., a vec3 load at 0x0f4) - Write masks on store[_per_vertex]_output - Indirect load/store where we need to use AL2P to get physical addresses, including scalarizing those cases It also handles the casses where we need to use ISBERD on vertex indices in the same pass. When we switch to this, we'll rip out the dedicated per_vertex lowering pass. Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/24998> |

`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.
