That's strange I was expecting this folder to be almost empty. Could you
do the same test from a GuixSD iso image, the 0.16 would be fine?

For the record, here's the output that Pierre Neidhardt gave me:

Without amdgpu:

--8<---------------cut here---------------start------------->8---
/sys/class/drm/ttm
/sys/class/drm/version
--8<---------------cut here---------------end--------------->8---

With amdgpu:
--8<---------------cut here---------------start------------->8---
/sys/class/drm/card0
/sys/class/drm/card0-DP-1
/sys/class/drm/card0-DP-2
/sys/class/drm/card0-DVI-D-1
/sys/class/drm/card0-HDMI-A-1
/sys/class/drm/card0-HDMI-A-2
/sys/class/drm/renderD128
/sys/class/drm/ttm
/sys/class/drm/version

Thanks for your help,

Mathieu
