Witold Baryluk e2b4247e40 zink: Cap PIPE_SHADER_CAP_MAX_CONST_BUFFERS to 32
PIPE_MAX_CONSTANT_BUFFERS is 32, however many Vulkan implementations
has maxPerStageDescriptorUniformBuffers that exceeds it, for example:

radv 8388606,
anv 64
nvidia 1048580 for RTX 2000 and up.

and, together with the current zink logic, the returned value
will exceed the maximum allowed value for the cap.

This causes cso_destroy_context to pass big values back to zink
(via zink_set_constant_buffer), resulting in access beyond end of
allocated buffer for all UBOs.

Cap the cap to PIPE_MAX_CONSTANT_BUFFERS (32), not INT_MAX.

Add an assert to verify future drivers.

======================================================


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
