Michal Wajdeczko bfbcf66186 drm/xe/pf: Use migration-friendly doorbells auto-provisioning
Instead of trying very hard to find the largest fair number of GuC
doorbell IDs that could be allocated for VFs on the current GT, pick
some smaller rounded down to power-of-two value that is more likely
to be provisioned in the same manner by the other PF instance:

  num VFs | num doorbells
  --------+--------------
   63..32 | 4
   31..16 | 8
   15..8  | 16
    7..4  | 32
    3..2  | 64
       1  | 128 (regular PF)
       1  | 240 (admin only PF)

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.
