I tested on the rockchip and on i915 (with a patch I am still working on for replacing cursors by async update), with igt plane_cursor_legacy and kms_cursor_legacy and I didn't see any regressions. I couldn't test on MSM and AMD because I don't have the hardware and my vc4 raspberry pi is not recognizing my display for some reason, I would appreciate if anyone could help me testing those. I also separated the patches per platform to be easier to get the tested-by tags, please let me know if it should be a single patch. Also, I added CC stable (as the "drm: Block fb changes for async plane updates" was also CCed to stable). I am not used to CC stable, please let me know if anything is off. Thanks!
