Mesa3D Graphics Library (Bleeding edge ray tracing branches)

Emma Anholt ea43465dbf Revert "freedreno: Cooperate with tc to stop checking the BC for resource_busy()."
This reverts commit 5cb043cf82.

While the numbers were impressive for drawoverhead, it comes at the cost
of additional flushes, which for gmem access (what we actually care about
most!) would greatly increase the actual cost to render.  Also, gl_driver2
overhead is increased, probably due to spending time in the kernel for the
flushes.

drawoverhead's win came from the increased flushing causing the GPU to
start processing the buffers sooner on everything but test 1, which
already had some incremental flushing happening.  That was certainly not
intended by the change.

`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>`_


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

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