I have tried your repository on branch rpi4-kms. The DRM VC4 is used! But got some issues: 1. Some weird error message in dmesg. Not sure it is related, or not [ 5.219321] [drm:vc5_hdmi_init_resources] *ERROR* Failed to get HDMI state machine clock https://gist.github.com/starnight/3f317dca121065a361cf08e91225e389 2. The screen flashes suddenly sometimes. 3. The higher resolutions, like 1920x1080 ... are lost after hot re-plug HDMI cable (HDMI0) Jian-Hong Pan
