Normally i85x/i865 3D activity will block FBC until a 2D blit occurs. I suppose this was meant to avoid recompression while 3D activity is still going on but the frame hasn't yet been presented. Unfortunately that also means that a page flipped 3D workload will permanently block FBC even if it only renders a single frame and then does nothing. Since we are using software render tracking anyway we might as well flip the chicken bit so that 3D does not block FBC. This will avoid the permament FBC blockage in the aforemention use case, but thanks to the software tracking the compressor will not disturb 3D rendering activity.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
