Patrick Lerda 085cfc98cc r600: fix cayman main non-deterministic behavior problem
Cayman has a non-deterministic behavior issue which is
visible with the test below (arb_shader_image_size).
The tests fail randomly at the "fragment" test category.
Anyway, if the "compute" category is removed, the same
tests are working flawlessly.

The "compute" part of the driver was interfering with the
graphic pipeline. The culprit is the packet PKT3_DEALLOC_STATE
which puts the gpu in an incorrect state to perform some
graphic operations.

This change fixes this problem by issuing a PKT3_CLEAR_STATE
packet just after the PKT3_SURFACE_SYNC packet. As explained
by d51dbe048a PKT3_DEALLOC_STATE is mandatory on cayman to
avoid a gpu hang at the PKT3_SURFACE_SYNC stage.

This correction makes tests like
"spec@glsl-4.30@execution@built-in-functions@cs-.*" to pass
in an utterly deterministic way without random failures.
This change removes around 500 random failures for a
"piglit run all".

For instance, this issue is triggered on cayman with
"piglit/bin/arb_shader_image_size-builtin -auto -fbo".

Fixes: d51dbe048a ("r600g/compute: Emit DEALLOC_STATE on cayman after dispatching a compute shader.")

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

You can find more information in our documentation (`docs/install.rst

Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ install
