Most BOs do not care at which offset they will be accessed within GGTT or PPGTT. The few which do care, should be only created on PF, and mapped within GGTT. On VFs, mapping at fixed offset is prohibited, as each VF is granted access to a range of GGTT address space. Since fixed addresses of GGTT mapping can only be used on PF, add an assert which makes sure no attempt of fixed placement will happen for a driver probed on a VF.

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 reStructuredText 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.
