I don't have one so I can't really tell for that specific board, but I'm go= ing to try to reproduce it on a rpi3b. > I tried to build kernel 5.5 and 5.6-rc2 in 32bit and aarch64=20 > configurations with VC4 turned ON but both unsuccessful - vc4 drm driver= =20 > is listed in memory but not working and not producing any typical DRM=20 > log output. AFAIK there is a known issue in 5.6-rc2, which has already been addressed[1= ]. Note that the driver fails on probe so there is some amount of DRM output. I tried to reproduce your issue with v5.5, but vc4 seems to probe alright (rpi3b+aarch64+defconfig): [ 15.443047] vc4_hdmi 3f902000.hdmi: vc4-hdmi-hifi <-> 3f902000.hdmi map= ping ok [ 15.452864] vc4_hdmi 3f902000.hdmi: ASoC: no DMI vendor name!
