Before commitbc0d7fdefe("drm: vkms: Supports to the case where primary plane doesn't match the CRTC"), the composition was executed on top of the primary plane. Therefore, the primary plane needed to cover the entire CRTC. After commitbc0d7fdefe, this is no longer necessary, as the composition is now executed on top of the CRTC. Then, allow the primary plane to be positioned in such a way that it doesn't cover the entire CRTC. This patch was tested with the vkms IGT testlist and all tests passed successfully. Moreover, the test igt@kms_universal_plane@universal-plane-pageflip-windowed-pipe-A used to fail and now is passing.

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.
