OpenGL doesn't have the concept of individual texture and sampler, so texture and sampler indexes have the same value. v3d compiler uses this assumption, so for example, the texture info at the v3d key include values that you need to use the texture format and the sampler to fill (like the return_size). One option would be to adapt the v3d compiler to handle both, but then we would need to adapt to the lowerings it uses, like nir_lower_tex, that also take the same assumption. We deal with this on the Vulkan driver, by reassigning the texture and sampler index to a combined one. We add a hash table to map the combined texture idx and sampler idx to this combined idx, and a simple array to the opposite map. On the driver we work with the separate indices to fill up the data, while the v3d compiler works with the combined one. As mentioned, this is needed to properly fill up the texture return size, so as we are here, we fix that. This gets tests like the following working: dEQP-VK.glsl.texture_gather.basic.2d.depth32f.base_level.level_2 Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6766> |

`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 `Freenode's #dri-devel <irc://chat.freenode.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.
