Re: current freebsd graphics stack

Isn't that the way it was done before and is done on DragonFly?

Don't forget, linuxkpi also supports AMD and Gallium drivers....

It is a complex subject.. in a perfect world we'd have unlimited time and
resources and FreeBSD would be in every man's hand  :)

Good luck!
