Francisco Jerez d57f3ced6c intel/fs: Calculate SWSB cross-pipeline synchronization information.
In combination with the previous changes we can just check whether an
instruction has any potentially unsatisfied dependencies on more than
one pipeline, and if so use TGL_PIPE_ALL synchronization with an
appropriate RegDist counter, otherwise synchronize with the single
pipeline it has a dependency on, if any.

Only minor difficulty is caused by the fact that the hardware doesn't
have any way to encode pipeline information when a RegDist and an SBID
dependency need to be provided simultaneously, in which case the
synchronization pipeline is inferred by the hardware.  We need to
verify that the hardware's inference will give the correct result
(which may not be the case if e.g. some data was bit-cast from a
different type), and if not emit separate SYNC instructions instead of
baking the RegDist dependency into the instruction (Note that SET SBID
dependencies must always be baked into the corresponding out-of-order
instruction).

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


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
<https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_


Bug reports
-----------

If you think something isn't working properly, please file a bug report
