Is anyone doing anything related to a universal memory abstraction in the Linux kernel? He speaks for around 5 minutes at the 20 minute mark about a unified memory architecture, and I just say hell yes. I think it might become one of the largest problems in the apu / dedicated card world, and just in general it is always an issue in a transition from dedicated plug in hardware cards with their own memories to integrated solutions using system memory. Having real universal reference would make all that a non problem.
