I don't think the display hardware really has such chroma
plane tile row alignment requirements as outlined in
commit d156135e6a ("drm/i915/tgl: Make sure a semiplanar
UV plane is tile row size aligned")
Bspec had the same exact thing to say about earlier hardware
as well, but we never cared and things work just fine.
The one thing mentioned in that commit that is definitely
true however is the fence alignment issue. But we don't
deal with that on earlier hardware either. We do have code
to deal with that issue for the first color plane, but not
the chroma planes. So I think if we did want to check this
more extensively we should do it in the same places where
we already check the first color plane (namely
convert_plane_offset_to_xy() and intel_fb_bo_framebuffer_init()).

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 reStructuredText 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.
