AMD is
preparing expanded HDMI 2.1 support for Linux, following earlier delays after the HDMI Forum
rejected an open source implementation of HDMI 2.1 as proprietary technology. As GamingOnLinux reports, AMD developer Harry Wentland submitted a
patch series to the Linux kernel mailing list, noting that it brings "HDMI FRL support to the amdgpu display driver" and that "DSC is still being tested and will be sent out later."
A forum post on Phoronix from an AMD driver developer also said "a full implementation will ultimately be available once the patches are ready and have completed compliance testing."
