Eric Anholt 2d7bcdaf6b ra: Add fast-path support for register classes of contiguous regs.
In the fully general case of register classes, to expose an allocation
class of unaligned 2-contiguous-regs allocations, for example, you'd have
your base individual regs (128 on intel), and another set of 127 regs that
each conflicted with the corresponding pair of the base regs.  Single-reg
nodes would allocate in the 128, and double-reg nodes would allocate in
the 127 and the user would remap from the 127 down to the base regs with
some irritating table.

If you need many different contiguous allocation sizes (16 is a pretty
common number across drivers), your number of regs explodes, wasting
memory and making the q computation expensive at startup.

If all the user has is contiguous-reg classes, we can easily compute the q
value up front (as found in the intel driver and nouveau, for example),
and we only have to change a couple of places in the conflict-checking
logic so the contiguous-reg classes can use the base registers.

`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
