Agreed.. Can you also discuss what is going on at the PCI-E level? How are the peer-to-peer transactions addressed? Is this elaborate scheme just a way to 'window' GPU memory or is the NIC sending special PCI-E packets at the GPU? I'm really confused why this is all necessary, we can already map PCI-E memory into user space, and there were much simpler patches floating around to make that work several years ago..
