Lionel Landwerlin 37f9788e9a anv: flush pipeline before query result copies
Pipeline state pending bits should be taken into account when copying
results.

In the particular bug below, the results of the
vkCmdCopyQueryPoolResults() command was being overwritten by the
preceding vkCmdCopyBuffer() with a same destination buffer. This is
because we copy the buffers using the 3D pipeline whereas we copy the
query results using the command streamer. Those pieces of HW work in
parallel and the results are somewhat undefined.

v2: Unconditionally flush the pipeline before copying the results
    (Jason)

v3: Wrap & expressions (Jason)

Build & install
---------------

You can find more information in our documentation (`docs/install.html
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.html <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>`_
