Danylo Piliaiev 5d377f435b freedreno/a6xx: Add EARLYPREAMBLE flag to all a6xx_sp_xs_ctrl_reg0
Each shader stage has its own "early preamble" flag.

Early preamble is likely an optimization to hide some of latency
when loading UBOs into consts in the preamble.

Early preamble has the following limitations:
- Only shared, a1, and consts regs could be used
  (accessing other regs would result in GPU fault);
- No cat5/cat6, only stc/ldc variants are working;
- Values writen to shared regs are not accessible by the rest
  of the shader;
- Instructions before shps are also considered to be a part of
  early preamble.

Note, for all shaders from d3d11 games blob produced preambles
compatible with early preamble mode.

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

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support
-------

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.
