HDMI 2.1 has long been a goalpost for many players in the Linux world, including Valve and AMD, who were both previously working on an open-source implementation of HDMI 2.1 drivers for the Linux kernel, despite roadblocks from the HDMI forum. Now, that appears to be a reality, with the Linux kernel mailing list citing patches that will likely be merged into the upstream kernel driver stack in Linux kernel 7.4
According to the merge request, HDMI 2.1 FRL will be landing in Linux with support for AMD FreeSync, VRR, and Auto Low-Latency Mode, all of which should be very useful for both desktop gamers and for couch gamers on machines like the Valve Steam Machine or its many SteamOS-touting alternatives. Linux kernel 7.4 is slated to land in October 2026, although an exact release date has yet to be determined. Valve also previously declared the work for HDMI 2.1 to be complete for the Steam Machine, although it seemingly has yet to implement the new driver in SteamOS, since the Steam Machine product page still cites HDMI 2.0.
