Hi Maxime, Thank you for your version 4 patch. I tested all 78 patches based on the next-20200708. Dual HDMI opearation does not work normally. flip_done timed out occurs and doesn't work. Could you check please it. [ 105.694541] [drm:drm_atomic_helper_wait_for_dependencies] *ERROR* [CRTC:64:crtc-3] flip_done timed out [ 115.934994] [drm:drm_atomic_helper_wait_for_dependencies] *ERROR* [CONNECTOR:32:HDMI-A-1] flip_done timed out [ 126.174545] [drm:drm_atomic_helper_wait_for_dependencies] *ERROR* [PLANE:60:plane-3] flip_done timed out And there is a problem with 4k UDH not outputting... So this problem worked as I fixed it like patches[1]. [1] [PATCH 0/3] drm/vc4: Support HDMI QHD or higher output "[PATCH v4 00/78] drm/vc4: Support BCM2711 Display Pipeline" all patches.
