I'm using amdgpu on a CIK ASIC (Hawaii Pro) and my monitor is connected by DisplayPort.

Do I still need to set this additional flag? If so I'd kindly request to at least fall back to amdgpu if somebody blacklisted radeon (or didn't compile it). Maybe issue a warning that not all features are supported yet. Thank you for your consideration! Cheers, Kai
