Patches Ready For AMDGPU HDMI 2.1 Enabled By Default With Linux 7.4 With FreeSync, VRR & ALLM
The AMDGPU open-source graphics driver is set to gain full HDMI 2.1 support enabled by default in Linux 7.4, including FreeSync, Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM). This follows years of the HDMI Forum rejecting HDMI 2.1 certification for the open-source implementation, a barrier that appears to have been overcome earlier in the year, reportedly with Valve's involvement. HDMI 2.1 Fixed Rate Link (FRL) patches first landed in Linux 7.2 but were disabled by default pending VRR readiness; a new feature pull request submitted for Linux 7.4 enables FRL by default alongside the FreeSync, ALLM, and VRR additions. The pull also includes updates for AMD's upcoming GFX12.1 graphics engine, DCN 6 display engine, and SMU 15 IP. Linux 7.4's merge window is expected to open in the second half of October, with a possible release around the end of the year or early next year.
