Not that I want to defend AMD but the reason they haven't been able to is because HDMI is a private spec and the HDMI forum specifically forbade them from releasing the driver they tried to publish a few years ago (even though the firmware with the actual implementation is in the GPU itself and still proprietary). That's why 2.1 works on windows and not Linux with the past 2 gens of AMD GPUs.
