- AMDGPU open-source Linux driver patches have been updated to include HDMI 2.1's Display Stream Compression (DSC) functionality.
- DSC enables higher resolutions and refresh rates such as 4K@240Hz and 8K@120Hz, using visually lossless, low-latency compression.
- The inclusion of DSC is part of the HDMI Fixed Rate Link (FRL) patch series aimed for the mainline Linux kernel.
- Full HDMI 2.1 implementation by AMD for the open-source driver is underway, though the reason for the previous block by the HDMI Forum remains unclear, with speculation about Valve's involvement possibly facilitating a compromise.
- Latest patches for HDMI FRL and FRL DSC are expected to be integrated in the next AMDGPU Display Core patch series, with upstream inclusion likely in the Linux 7.2 kernel cycle.
