Quick reminder on the likely reason why Valve's New Steam Machine only supports #HDMI 2.0:

""At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements.""

This is what Alex Deucher, the maintainer of the amdgpu #kernel driver, said one and a half years ago here:

https://gitlab.freedesktop.org/drm/amd/-/issues/1417#note_2303163

And from the ticket it looks like the problem remains.

See also Alex's earlier comment from early 2021 in the ticket:

""HDMI 2.1 is not available on #Linux due to the HDMI Forum.""

@kernellogger@hachyderm.io Is the Chinese GPMI Free to use? If yes, ditch the HDMI Forum.
