It sounds to me like the most difficult facility there to implement well so they must have some good reason in mind. Perhaps it could be used to for instance ensure all the writes to some GPU memory are sent off to it without bothering about any other memory. But they're going full steam with HSA anyway and they would only put in something like this I think if it made a sizable difference for servers. It is quite intriguing.
