I would like to be able to extend an existing registration such that the driver would take advantage of the fact that part of the extended registration is already registered, i.e. only the "new" memory would be pinned and made resident.
Assuming you are referring to registration of virtual memory from user space, this seems as a request for the hw drivers to support overlapping memory regions in the sense that MR A can overlap with MR B such that till both A and B are unregistered the overlapped section is in place (pinned , resident, mapped in the HCA MMU etc).
although we would prefer that it wouldn't block if possible
mmm. All the current memory registration verbs both user and kernel are blocking, is it an issue for you?
