Fast memory registration. It is an optimization of the HCA to perform registration faster than regular memory region. >b) In absence of FMR support what is the buffer management scheme for Z-Copy? >Will SDP work without FMR?

Haven't looked deeply into it, but I think that ehca has done this. >c) How page locking and virtual to physical address conversion is done for Z- >Copy buffers?
