Hello, This patch series fixes support for planes that cross the screen boundaries. The KMS API supports such a configuration, but the DU and VSP hardware doesn't. This leads to different kind of dispay artifacts or hangs. The series starts with a bit of refactoring to share existing code and make it easier to share new code. The second patch then clips planes that are either partially or fully off-screen, disabling planes that end up being completely invisible. Compared to v2, the series has been rebased on top of the latest drm+drm-misc to benefit from Ville's rework of the plane state check helper, and now actually uses the clipped source and destination rectangles (and hence passes the tests). Compared to v1, fully off-screen planes are now accepted (but obviously not shown). The patches are based on top of Dave's latest master branch. The series has been tested on a Salvator-XS board.
