AMD has expanded its open-source Linux driver support with patches enabling HDMI 2.1 Display Stream Compression (DSC) functionality. Following initial Fixed Rate Link (FRL) support announced earlier this month, the updated patches now allow for higher resolutions and refresh rates through this visually lossless compression technology.

The DSC implementation enables impressive display capabilities like 4K@240Hz and 8K@120Hz with improved bandwidth efficiency. AMD's work on a complete HDMI 2.1 implementation addresses previous restrictions that prevented open-source code sharing, with speculation suggesting Valve's involvement helped overcome HDMI Forum limitations.

The latest patch series should integrate with the next AMDGPU Display Core patches, making this feature likely to appear in the mainline Linux kernel with the upcoming Linux 7.2 release. This advancement provides Linux users with high-performance display options previously unavailable.
