drm_plane_state->src is modified when offset is calculated: before calculation: src.x1 = 8192, src.y1 = 8192 after calculation (pitch = 65536, cpp = 4, alignment = 262144) src.x1 = 8192, src.y1 = 0, offset = 0x20000000 Damage clips are relative to original coodrdinates provided by user-space. To compare these against src coordinates we need to use original coordinates as provided by user-space. These can be obtained by using drm_plane_state_src.

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.
