Adjust eligibility check on imageExtent vs slice dimensions rather than on the buffer addressing dimensions. The TFU codepath here always writes/reads the full slice from its origin, so the required invariant is 'imageExtent == slice'; bufferRowLength and bufferImageHeight may be larger than imageExtent (the spec permits this for non-zero values), in which case the TFU reads/writes at the buffer's row/layer stride but only touches slice->width pixels per row and slice->height rows per layer, leaving the trailing padding untouched. The previous combined check (width == slice->width && height == slice->height applied to the buffer dimensions) would reject any caller that set bufferRowLength or bufferImageHeight larger than the image (this is common for buffers shared across mip levels or for alignment requirements like Dawn aligning bufferRowLength to 2 for 1-pixel-wide textures), forcing those copies through the slower TLB / blit / compute paths. For compressed formats, keep the strict equality check since block-level stride semantics are more complex.

`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.
