Typical Phorinix. Wil not elaborate what FRL is.

The first paragraph:

It's not complete HDMI 2.1 support but to much surprise hitting the mailing list today were official patches from AMD for implementing HDMI Fixed Rate Link "FRL" support for their kernel graphics driver. HDMI FRL as part of HDMI 2.1+ allows for higher bandwidth to support higher refresh rates and resolutions.

How much more of an explanation do you need?

Fixed Rate Link.

I’m no expert, but basically the way to unlock higher/full bandwidth for HDMI 2.1. This will allow the use of higher refresh rate, resolution, and bit depth + HDR. Right now you need to make sacrifices in at least one category with HDMI

Yeah I know the issue. You can run 4k TV at 120hz through it but it will use chroma subsampling to run on limited bandwidth.
