The GC880 on iMX6DL indicates in it's minorFeatures2 register that it does support SEAMLESS_CUBE_MAP, however when the TE.SAMPLER_CONFIG1 VIVS_TE_SAMPLER_CONFIG1_SEAMLESS_CUBE_MAP bit is set on GC880 on iMX6DL, the result is corrupted image. In particular, the following ~112 dEQPs are affected and fail: dEQP-GLES2.functional.texture.filtering.cube.* This only happens on MX6DL GC880, MX6Q GC2000 and STM32MP1 GC400(GCnano) do not report the minorFeatures2 SEAMLESS_CUBE_MAP bit and ignore the TE_SAMPLER_CONFIG1 VIVS_TE_SAMPLER_CONFIG1_SEAMLESS_CUBE_MAP bit (note that ss->seamless_cube_map is unconditionally set by mesa at times even PIPE_CAP_SEAMLESS_CUBE_MAP_PER_TEXTURE returns 0), so there is no visible problem and there are no failing dEQP tests on the GC2000 and GCnano. This might imply that the minorFeatures2 SEAMLESS_CUBE_MAP has some different meaning on GC880 or the SEAMLESS_CUBE_MAP behaves differently on the GC880. This patch does not set the SEAMLESS_CUBE_MAP bit on hardware which does not indicate support for seamless cube map and on GC880, which results in reduction in failed dEQPs: 635 to 186 on GC880, 274 to 270 on GC2000 and no change on GC400(GCnano).

`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.html <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.html <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.html <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.html <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
