For geometry shaders, we're going to need to compile various graphics shaders down to compute shaders. This means that they'll look like compute shaders to much of the compile pipeline but ultimately get executed as graphics shaders. Most of the time, the compiler will just happily take whatever offset you give and try to load the sysval from there so you can load a graphics sysval from a compute shader just fine. However, for the common ones, we switch on the shader stage and load from a different offset for 3D vs. compute. This breaks the moment you have a compute shader that's going to actually load from a 3D sysval space. The solution here is to ensure that any common sysvals (currently just the push uniforms address and the printf buffer) are at exactly the same offset in both. This is done by adding a panvk_common_sysvals struct, some static asserts, and a bit of macro magic to keep things eurgonamic. This also changes push uniform upload to just swap in the push uniform address instead of writing it to the command buffer on every iteration.

`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.
