From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxxx> Consolidated series as an simpler alternative to https://lore.kernel.org/dri-devel/20241024124159.4519-3-christian.koenig@xxxxxxx/. Hopefully fixes https://gitlab.freedesktop.org/drm/amd/-/issues/3617. First two patches are fixes followed by one optimisation and then Christian's and my selftest additions. Cover letter now because it grew to five patches. Please test and/or suggest more test cases to look at.
