Our fence management is lazy, very lazy. If the user marks an object as untiled, we do not immediately flush the fence but merely mark it as dirty. On the next use we have to remember to check and remove the fence, by which time we hope it is idle and we do not have to wait. v2: Throw away the old fence on the next ggtt_pin.

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.
