Noob question - how does RDMA integrate with the out of tree junk? AFAIU it's possible to run the "in-tree" RDMA stack and get "GPU direct". Both Jonathan in the past (Meta) and now Mina (Google) are trying to move the needle and at least feed the GPUs over TCP, instead of patented, proprietary and closed RDMA transports.
