[Why] Tiling and DCC attributes can change when swapping framebuffers but these will only ever get updated on full commits where state->allow_modeset is true. But for the page-flip IOCTL state->allow_modeset = false so these aren't updated and DCC changes aren't being programmed. [How] Split out updating the tiling and DCC attributes into its own function that's called when creating the plane for the first time but also called when switching framebuffers before commit stream updates. These functions also don't modify the plane state directly since the plane state being used as reference is often the current one being used by the hardware. DC needs to be able to compare plane_state to the stream update structures to determine if the hardware programming should happen. If it's modified in place then nothing will be programmed and we can run into concurrency issues.

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.
