Alyssa Rosenzweig 04360a270e asahi: Copy panfrost's bo cache
Massive performance gains, some fps before/after numbers from glmark2:

   [shading] 1486 -> 2391
   [refract] 87   -> 127
   [terrain] 32   -> 56

...and it's basically for free with enough copy/paste, so thank you to Boris
Brezillon for an excellent Asahi patch, the LRU cache seems to work great on M1
:-p

There are a few minor changes I made from panfrost, notably adjusting the
constants to account for 16KiB pages and switching from pthread_mutex to
simple_mtx to be less weird in Mesa.

For context on the design, the following commits evolved it in Panfrost and
their commit messages may be useful... The logic in this module is the product
of years of mistakes and correcting course :-)

   f06809cdca ("panfrost: Evict the BO cache when allocation fails")
   77d0498913 ("panfrost: Fix major flaw in BO cache")
   ee82f9f07e ("panfrost: Try to evict unused BOs from the cache")
   2225383af8 ("panfrost: Make sure the BO is 'ready' when picked from the cache")
   9af4aeaaf7 ("panfrost: Don't return imported/exported BOs to the cache")

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
