You should call ibv_ack_cq_events after ibv_get_cq_events but before ibv_destroy_cq. That can come before or after calling ibv_poll_cq. And, although it's probably easiest to call ack after get, note that you don't need a 1:1 call ratio between get/ack. You can keep a count of the number of times that ibv_get_cq_events returns a specific cq, and then call ibv_ack_cq_events for that amount just before calling ibv_destroy_cq. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
