For cases when less than 4 components are read, the original code would compute an incorrect dmask. eg: with a single component + is_sparse, the dmask was 0x13: - 0x 3 = coming from nir_def_components_read - 0x10 = the sparse bit While it should have at 2 bits set (1 for the color/depth, 1 for tfe). This caused problem when expand_vector() used the dmask to generate the final results, because the value for the sparse component was read from the wrong index. So after the call to emit_mimg() dmask needs to be adjusted because the components will be stored in order, so if mask is 0x11 the tfe value would be stored at invalid index=5 (while it should be at index=1). This fixes KHR-GL46.sparse_texture_clamp_tests.SparseTextureClampLookupResidency_texture_2d_depth_component16 and KHR-GL46.sparse_texture2_tests.SparseTexture2Lookup_texture_2d_depth_component16 with ACO.

`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.
