Can you write a kernel patch / driver to trap the unsupported instructions and provide software implementations?

Rva20 lacks vector support and hypervisor instructions, among other things.

You’re welcome to put a ton of effort in for dogshit performance on a bunch or $35 SBCs but the rest of us will just upgrade

And don’t worry, some vendor won’t come in and magically save you - fedora is eyeing rv22 as their baseline.

That's the problem with open source, a bunch of people who once in their life want to "do it right" (right never comes). No adults in the room to say "this is what you got".

From a billion python packages in distribution package managers to broken screen sharing in Wayland, "right" isn't even what anyone wants.
