Sure, but you can't just return from the CQ upcall after doing a budget and expect to be called again in the future. That is absolutely wrong. It is very difficult to mix and match processing in the CQ upcall and in another context. So, either you drain the whole thing in the CQ upcall, or delegate to another context and process it there, possibly sleeping during processing when the budget is hit. Overall, the process is the same, drain entirely before calling ib_req_notify_cq, don't expect any CQ upcalls until ib_req_notify_cq is called.
