OpenGL 3.0 requires ARB_texture_float, which technically speaking requires linear-filtering support for FP32 textures. However, because a lot of early implementations just ignore this and does nearest filtering instead due to lack of hardware features for this, this functionality was never added to the OpenGL CTS. The result is that FP32 is a feature that is required on paper, but is unreliable to be used by applications in practice. This is mostly fine; for most filterable use-cases (e.g colors), FP16 is fine and saves a bunch of bandwidth, and for cases where you really need the extra bits (depth-reads etc), filtering is usually not what's wanted. To save drivers that doesn't support filtering of FP32 filtering from having to manually whack the state, and get needless CSOs in the CSO caches, let's force this in early, where we already do the same for integer textures.

`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 `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://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.
