Is this because of HDCP?
No, patents.
So I still don’t quite understand patents,
Does it forbid someone from selling the intention? Making the invention? Can I not even make an invention for personal use if it’s patented??
I think you can generally make one, but it has to be for personal use and you can’t ever sell it.
is amd having support on the linux kernel counting as selling?
No but it isn’t for personal use. You likely wouldn’t be able to get the specs to do it for yourself either though.
A speculation, https://www.phoronix.com/news/HDMI-2.1-OSS-Rejected, about HDCP, i.e. not exposing technical details as to prevent video copying, was offered.
In practice probably largely. But I doubt they say explicitly.
