Store an instance of struct drm_format_conv_state in the shadow-plane state struct drm_shadow_plane_state. Many drivers with shadow planes use DRM's format helpers to copy or convert the framebuffer data to backing storage in the scanout buffer. The shadow plane provides the necessary state and manages the conversion's intermediate buffer memory.

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.
