[Why] Pitch, DCC, rotation and mirroring can result in updates that are not UPDATE_TYPE_FAST but UPDATE_TYPE_MED instead. DC needs dc_plane_info and dc_plane_size to make this determination and we aren't currently passing this into DC during atomic check. Underflow (visible or non-visible) can occur if we don't validate this correctly. This also will generally trigger p-state warnings, typically via the cursor handler when locking. [How] Get the framebuffer tiling flags and generate the required structures for DC in dm_determine_update_type_for_commit.

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.
