Therefore, the primary plane needed to cover the entire CRTC. After commit bc0d7fdefec6, 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.
