--- Comment #16 from Michel Dänzer michel@daenzer.net --- (In reply to Carlo Caione from comment #15)
With an amd-staging-* kernel branch and DC enabled, you can try tweaking dce_v11_0_crtc_do_set_base to pass AMDGPU_GEM_DOMAIN_GTT instead of / in addition to AMDGPU_GEM_DOMAIN_VRAM to amdgpu_bo_pin. [...]
I tried amd-staging-4.11 and interestingly dce_v11_0_crtc_do_set_base is called only when DC is disabled.
Right, sorry, with DC you need to tweak dm_plane_helper_prepare_fb instead.
