As we recently discovered, the layout of level L of a mipmapped 2D image of size WxH is /not/ the same as the layout of a non-mipmapped 2D image of size minify(W, L) x minify(H, L). The difference occurs due to subtleties of the "power of two" miptrees which can force a level to use a larger tile size than it would have required at root level. To handle this quirk correctly, the driver must not implement texture views with address arithmetic -- it must supply instead the base width/height of a texture and use first/last level fields on the texture descriptor to map it. Similar issues occur when writing a particular level of a mipmapped texture, which was handled correctly in the colour case but not the Z/S case. Fixes dEQP-GLES2.functional.texture.mipmap.cube.generate.* Signed-off-by: Alyssa Rosenzweig <alyssa@rosenzweig.io> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/18380>

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 `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary.
