When sampling a subpass input attachment when multiview is been used the the view index is required. This becomes an extra output from the vertex shader which is then iterated into the fragment shader input where it is then used as the array layer index when sampling the subpass input attachment. However this extra output was not having its interpolation mode configured correctly leading to incorrect instructions being added causing the view index to always be zero and thus sampling the subpass input attachment incorrectly. Fix is to make sure the view index interpolation mode is set to flat. Fix: dEQP-VK.multiview.input_attachments.no_queries.1_2_4_8_16_32 dEQP-VK.multiview.input_attachments.no_queries.1_2_4_8 dEQP-VK.multiview.input_attachments.no_queries.15_15_15_15 dEQP-VK.multiview.input_attachments.no_queries.15 dEQP-VK.multiview.input_attachments.no_queries.5_10_5_10 dEQP-VK.multiview.input_attachments.no_queries.8_1_1_8 dEQP-VK.multiview.input_attachments.no_queries.8 dEQP-VK.multiview.input_attachments.no_queries.max_multi_view_view_count dEQP-VK.multiview.renderpass2.input_attachments.no_queries.1_2_4_8_16_32 dEQP-VK.multiview.renderpass2.input_attachments.no_queries.1_2_4_8 dEQP-VK.multiview.renderpass2.input_attachments.no_queries.15_15_15_15 dEQP-VK.multiview.renderpass2.input_attachments.no_queries.15 dEQP-VK.multiview.renderpass2.input_attachments.no_queries.5_10_5_10 dEQP-VK.multiview.renderpass2.input_attachments.no_queries.8_1_1_8 dEQP-VK.multiview.renderpass2.input_attachments.no_queries.8 dEQP-VK.multiview.renderpass2.input_attachments.no_queries.max_multi_view_view_count Signed-off-by: Nick Hamilton <nick.hamilton@imgtec.com> Reviewed-by: Simon Perretta <simon.perretta@imgtec.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/39715> |

`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.
