There is no need check if PPGTT is disabled because that not possible in CNL. Execlists and GuC submission modes rely on at least aliasing PPGTT and even intel_sanitize_enable_ppgtt says: "We don't allow disabling PPGTT for gen9+ as it's a requirement for execlists, the sole mechanism available to submit work."

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
