IIRC rdmacm does not forward these events. There is a lot missing to support APM with RDMA CM, it doesn't do any of the CM state machine operations to coordinate loading alternate paths, for instance. > As soon as the migration happens I expect that a IB_EVENT_PATH_MIG* is > generated on the QP event handler, but I don't receive any QP events. qp_event_handler is a RDMA CM event handler, it handles RDMA_CM_EVENT_* and there is no RDMA_CM_EVENT_PATH_MIGRATED. You'd need to listen to the verbs level events directly, I don't recall if this is possible with RDMA CM or not, sorry.
