Nanley Chery de04140973 intel/blorp: Avoid 32bpc fast clear sampling issue
For 32bpc formats, the ICL+ sampler fetches the raw clear color dwords
used for rendering instead of the converted pixel dwords typically used
for sampling. The CLEAR_COLOR struct page documents this for 128bpp
formats, but not for 32bpp and 64bpp formats.

In blorp_copy, map R11G11B10_FLOAT to R8G8B8A8_UINT instead of R32_UINT.
This will cause the sampler to fetch the clear color pixel, allowing
drivers to keep clear color support enabled during copies.

If iris is forced to convert blits to copies, this patch fixes the
following test on gfx12:

  dEQP-GLES3.functional.fbo.color.repeated_clear.blit.rbo.r11f_g11f_b10f

At the moment, both iris and anv won't hit this issue outside of
blorp_copy. This is due to the read/write access restrictions they
currently place on texture views that reinterpret the surface format.

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

.. 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.
