Matthew Auld fff1d972f4 drm/doc: add rfc section for small BAR uapi
Add an entry for the new uapi needed for small BAR on DG2+.

v2:
  - Some spelling fixes and other small tweaks. (Akeem & Thomas)
  - Rework error capture interactions, including no longer needing
    NEEDS_CPU_ACCESS for objects marked for capture. (Thomas)
  - Add probed_cpu_visible_size. (Lionel)
v3:
  - Drop the vma query for now.
  - Add unallocated_cpu_visible_size as part of the region query.
  - Improve the docs some more, including documenting the expected
    behaviour on older kernels, since this came up in some offline
    discussion.
v4:
  - Various improvements all over. (Tvrtko)

v5:
  - Include newer integrated platforms when applying the non-recoverable
    context and error capture restriction. (Thomas)

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.
