Hi Maxime, Thanks for your version 4 patch again. I took the patches and applied them upon next-20200708. I make system cold reboot to multi-user target and the text console shows on the screen. Then, I simply hot re-plug the HDMI cable on HDMI0 port, I not only lose the text console on the screen (the display shows blank, backlight is off), but also kernel does not probe modes for the HDMI connector again. But HDMI1 does probe modes again for hot re-plugging. So, HDMI1 does not hit the issue like HDMI0. * System probes modes only once for HDMI0 port (HDMI-A-1), even hot re-plug HDMI cable to the same port: [ 15.611072] [drm:drm_helper_probe_single_connector_modes] [CONNECTOR:32:HDMI-A-1] probed modes : [ 15.611079] [drm:drm_mode_debug_printmodeline] Modeline "1920x1080": 60 148500 1920 2008 2052 2200 1080 1084 1089 1125 0x48 0x5 [ 15.611085] [drm:drm_mode_debug_printmodeline] Modeline "1920x1080": 60 148500 1920 2008 2052 2200 1080 1084 1089 1125 0x40 0x5 ...

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.

Nevermind, I had the DSI panel connected and it was interfering Maxime
