Stanislav Lisovskiy 9728889f42 drm/i915: Use bw state for per crtc SAGV evaluation
Future platforms require per-crtc SAGV evaluation
and serializing global state when those are changed
from different commits.

v2: - Add has_sagv check to intel_crtc_can_enable_sagv
      so that it sets bit in reject mask.
    - Use bw_state in intel_pre/post_plane_enable_sagv
      instead of atomic state

v3: - Fixed rebase conflict, now using
      intel_atomic_crtc_state_for_each_plane_state in
      order to call it from atomic check
v4: - Use fb modifier from plane state

v5: - Make intel_has_sagv static again(Ville)
    - Removed unnecessary NULL assignments(Ville)
    - Removed unnecessary SAGV debug(Ville)
    - Call intel_compute_sagv_mask only for modesets(Ville)
    - Serialize global state only if sagv results change, but
      not mask itself(Ville)

v6: - use lock global state instead of serialize(Ville)
v7: - use both global state lock and serialize depending on
      if we need to change only global state or access hw
      (Ville)

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.
