Iago Toral Quiroga aebb47b7d1 compiler/nir: add a divergence analysis option for non-uniform workgroup id
The V3D hardware allows us to pack multiple workgroups together to avoid
wasting execution lanes in shader cores.

For example, if we dispatch 16 workgroups with a local size of 1 element, we
can pack all 16 workgroups in a single 16-wide dispatch where each lane
executes a different workgroup, instead of 16 1-wide dispatches.

When we do this, we don't have a uniform workgroup id any more.

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
