channel datatypes in Mesa are the host's endianness. For example, PIPE_FORMAT_R32_UINT doesn't do a bswap in and out in u_format_table.c's pack/unpack functions. So, z32_unorm shouldn't be byte swapping either, and neither should z24s8 which is also a packed format, and once you've got those it becomes clear that all of the swaps in this file were mistaken. Things would mostly work out because it's unusual to read/write Z/S data through the GL API, and even for drivers like softpipe as long as the pack and unpack both swap it could work anyway. However, the bug would be visible in glReadPixels() with the matching datatype which would hit the memcpy fastpath without doing another swap. Caught by a mesa/main unit test on transitioning to using these pack/unpack functions.

`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.
