Stanislav Lisovskiy b06cf59533 drm/i915: Move dbuf slice update to proper place
Current DBuf slices update wasn't done in proper
place, especially its "post" part, which should
disable those only once vblank had passed and
all other changes are committed.

v2: Fix to use dev_priv and intel_atomic_state
    instead of skl_ddb_values
    (to be nuked in Villes patch)

v3: Renamed "enabled_slices" to "enabled_dbuf_slices_num"
    (Matt Roper)

v4: - Rebase against drm-tip.
    - Move post_update closer to optimize_watermarks,
      to prevent unneeded noise from underrun reporting
      (Ville Syrjälä)

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.
