Ilia Mirkin 729020c7e0 nv50: fix streamout queries
Prior to an earlier commit, xfb queries were not being marked as 64-bit.
The end result of this is that they would never appear to be "ready",
which in turn led to there always being a wait happening.

Once these got marked as 64-bit, we started checking the attached fence
for being signalled. However the screen fence does not seem to be enough
to wait for the streamout query data to actually be written out. So
instead we add a bit of extra "data" which emulates the 32-bit query way
of doing things (with the payload in front) which is emitted from the
same "unit" as the other streamout data. This seems to be sufficient.

Note that it does not seem to be required to actually emit the final
32-bit query from the streamout unit, but that seems logical and perhaps
there are edge cases where it is required.

While at it, also make the sequence management/initialization more
similar to the nvc0 driver.

Fixes dEQP-GLES3.functional.transform_feedback.*

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library
======================================================


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 `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.
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>`_
