Hi all, This is an update to Bug#968181: linux-image-5.7.0-2-arm64: DRM unavailable on Rapsberry Pi 4B
I compiled Linux 5.10.9 by myself, and xinit starts fine without installing the Debian package xserver-xorg-video-fbdev. When I originally reported this #968181, the graphics on my raspi can only be used through xserver-xorg-video-fbdev. X server works fine by using /dev/dri/card0 on my raspi 4B 8GB model. DRI/DRM on raspi started to partially work. On the other hand, gdm3 and weston gives the following error in dmesg, "kernel: [drm:vc4_bo_create [vc4]] *ERROR* Failed to allocate from CMA:" and no graphics come. Rendering by wayland does not work at all with vc4.ko in 5.10.9. Best regards, Ryutaroh
