OpenGL 3.0 requires the driver can draw to 8 simultaneous render
targets. Similarly, OpenGL ES 3.0 requires the driver can draw to 4
simultaneous render targets. Fix the version computation logic to take
this into account.
On Mali T720, we support ~all features of OpenGL ES 3.1 except we only
support a single render target. Mali T720 should advertise OpenGL 2.1
and OpenGL ES 2.0 only. With the previous logic, it incorrectly
advertised OpenGL ES 3.1.
v2: Lie about the minimum for GL 3.0 to make freedreno a3xx happy. Add
Emma's reviewed-by.
v3: Update the Mali T720 CI expectations. There are tests that pass on
GLES3 but not GLES2. Unclear if these are dEQP bugs or Mesa bugs, lima
hits the same issues. Add them to the known fails
Note to mesa-stable maintainers: this downgrades the OpenGL version
advertised on Mali T720. As such, this patch should apply to the
unreleased 21.3 (Eric) but should NOT be backported to any released Mesa
versions (21.2 or older should NOT have this patch). This is a bit of a
compromise; Emma agreed with this plan on IRC.

`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.
