Define a common set of Xe2 graphics feature flags and definitions that will be used for all platforms in this family. Several of the feature flags are inherited unchanged from Xe_HP and/or Xe_HPC platforms: - dma_mask_size remains 46 (Bspec 70817) - supports_usm=1 (Bspec 59651) - has_flatccs=1 (Bspec 58797) - has_asid=1 (Bspec 59654, 59265, 60288) - has_range_tlb_invalidate=1 (Bspec 71126) However some of them still need proper implementation in the driver to be used, so they are disabled. Notable Xe2-specific changes: - All Xe2 platforms use a five-level page table, regardless of the virtual address space for the platform. (Bspec 59505) The graphics engine mask represents the Xe2 architecture engines (Bspec 60149), but individual platforms may have a reduced set of usable engines, as reflected by their fusing.

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.
