The new code doesn't reveal any key details about any power management changes coming with the next-gen AMD graphics. In any event it's good seeing this code continue to flow out pre-launch so that it will ideally be all upstreamed in the mainline Linux kernel prior to any graphics processors appearing with this new IP.
