/dev/dri missing on CM4

Hi,
I’m having some trouble with accessing /dev/dri/card0 or /dev/dri/card1

When using the Raspberry Pi CM4 IO Board, the /dev/dri devices are missing.
Using DT Overlay "vc4-fkms-v3d" does not make a difference, and using SSH to the host OS shows that /dev/dri does not exist.

Attaching a display (not possible for the project in production) & even attempting to run the balenablocks/xserver example is also unsuccessful.

Is there a configuration option that I am missing? There does not seem to be any information on being able to enable & access DRI.

Thanks in advance

Hi @mckelvaney

We’ve released a new version (v2.94.4) for the CM4 IOboard that should fix this issue you’re experiencing. Feel free to test it and let us know if you still see the same problem.

Cheers,
Nico.
