Yiwei Zhang 1ea949429c egl/android: fix cached buffer slots for EGL Android winsys
Android WSI api contract requires to allocate min_undequeued_buffers + 2
to achieve "triple buffering" effect, which is when the composer backend
acquired the allowed max numbder of buffers, the producer still has 2
buffers to rotate.

ANativeWindow either belongs to SurfaceView which presents directly to
SurfaceFlinger or belongs to other surfaces from the UI framework. For
the former, SurfaceFlinger hardcodes triple buffering for EGL. For the
latter, the surface caps decide the buffer limits or HWUI intercepts and
adjusts the min_undequeued_buffers to hint the EGL implementation to
prepare enough buffer cache slots while HWUI sets the max dequeued
buffer count accordingly.

`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>`_
