In attachment what I get when using AMDGPU_GEM_DOMAIN_GTT.
[...]
[drm:dm_plane_helper_prepare_fb [amdgpu]] *ERROR* Failed to pin framebuffer
Do you also get those errors with AMDGPU_GEM_DOMAIN_GTT? If so, it might be interesting to track down the origin of the errors. Otherwise, it looks like there's still something missing.
