--- Comment #5 from Emil Velikov <emil.l.velikov at gmail.com> ---
That's because the drmDevice API retrieves the device revision id.

IIRC that was something explicitly requested by Jammy and the only way to get
the info is to parse ./config which wakes up the device.

AFAICT if using libudev one also needs to parse ./config since the kernel does
not expose a revision_id file/info like the {subsystem_,}{device,vendor} ones.

I think we'd really want to change that [in the long term]. There was a patch
for it, but seems like it never got sent/merged.
