We don't want to use the FBC hardware render tracking so let's not enable it. To use the hw tracking properly we'd anyway need to integrate this into the command submissing path as the register is context saved, and if rendering happens via the ppgtt we'd have to configure it with the ppgtt address instead of the ggtt address. Easier to use software tracking instead. Note that on pre-ilk we can't actually disable render tracking. However we can't rely on it because it requires that DSPSURF to match the render target address, and since we play tricks with DSPSURF that may not be the case. Hence we shall rely on software render tracking on all platforms.

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.
