 968181 missing DRI/DRM support on Raspberry Pi
 968188 4K display resolution is not recognized with Raspberry Pi 4B

I confirm that vc4.ko in 5.10.5-1 can show 4K output and it provides /dev/dri/card0.
The gdm3 display manager and the gnome session (both using wayland) work well
with vc4.ko on my raspi 4B 8GB mode.

Some comments:
The default CMA size 64 MB is insufficient for gdm3 with 4K resolution as reportet at
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=980536

"disable_fw_kms_setup=1" is necessary in "config.txt" of raspi, as reported at
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977642

The latter is actually a bug in the upstream kernel. Today I was told that
it has been fixed upstream at the dri-devel mailing list from Maxime Ripard.

Best regards, Ryutaroh Matsumoto

 968181 missing DRI/DRM support on Raspberry Pi

Since gpu/drm/vc4.ko is disabled in 5.10.9-1 while it was enabled in 5.10.5-1,
the above two issues have come back (I unwelcome them...).

Indeed, CONFIG_DRM_VC4=m has been mistakenly removed from the arm64 kernel
configuration. I’ll propose a merge request to fix this.

Thank you. I though that the kernel team decided to suspend vc4.ko,
because of the garbled unreadable screen as reported at
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=980785
originally found by Lucas.

Best regards, Ryutaroh
