Re: AMD integrated graphics passthrough to KVM guest

Hello Alex,

thank you very much for your answer.

I assume when you say "non-primary," you refer to graphics adapters
that are not used to display POST and kernel messages?
Although I know C, I've never worked on hardware-related tasks, so I'm
afraid I won't be of much help in adding support, unless you think
it's a task that is suitable for a newcomer. In any case, I'd be happy
to help by testing suggestions by you or others.

I've pulled that card out of an old computer that I haven't bought.
It's manufactured by MSI, but other than that, I haven't found make or
model names. lspci says it's an "ATI RV515 [Radeon X1300]."

Thanks!
