HDMI Discussion board Rejects Open-Supply HDMI 2.1 Driver Assist Sought By AMD


One of many limitations of AMD’s open-source Linux graphics driver has been the shortcoming to implement HDMI 2.1+ performance on the premise of authorized necessities by the HDMI Discussion board. AMD engineers had been working to provide you with an answer along side the HDMI Discussion board for having the ability to present HDMI 2.1+ capabilities with their open-source Linux kernel driver, nevertheless it seems like these efforts for now have concluded and failed.
For 3 years there was a bug report round 4K@120Hz being unavailable via HDMI 2.1 on the AMD Linux driver. Equally, there have been bug experiences like 5K @ 240Hz not possible both with the AMD graphics driver on Linux.
As coated again in 2021, the HDMI Forum closing public specification access is hurting open-source support. AMD in addition to the X.Org Basis have been engaged with the HDMI Discussion board to attempt to provide you with an answer to have the ability to present open-source implementations of the now-private HDMI specs.
AMD Linux engineers have spent months working with their authorized group and evaluating all HDMI options to find out if/how they are often uncovered of their open-source driver. AMD had code working internally after which the previous few months have been ready on approval from the HDMI Discussion board… Sadly, the HDMI Discussion board has turned down AMD’s request for open-source driver assist.
AMD Linux engineer Alex Deucher commented on the ticket:
“The HDMI Discussion board has rejected our proposal sadly. At the moment an open supply HDMI 2.1 implementation will not be potential with out working afoul of the HDMI Discussion board necessities.”
Thus a tragic day for open-source GPU drivers with no obvious answer to securely implement HDMI 2.1+ performance inside open-source show drivers…
Evidently, open-source Linux advocates ought to attempt to use DisplayPort as a substitute if in any respect potential.
