Some applications explicitly call glTex[ture]Parameteri[v] to set GL_TEXTURE_MAX_LEVEL and GL_TEXTURE_BASE_LEVEL before uploading any texture data. Core Mesa initializes MaxLevel to 1000, so if it isn't that, we know they've set it. (We check for < TEXTURE_MAX_LEVELS to avoid hardcoding that value, however.) If MaxLevel - BaseLevel > 0, then the app is trying to tell us that this texture is going to have multiple miplevels. In that case, go ahead and allocate the space for it. Avoids many resource_copy_region calls at texture finalization time in the Civilization VI benchmark.

`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>`_).
