[dpdk-users] rte_eth_rx_queue_setup:err=-22

[Matthias Pölzinger]

Hi,

 

I‘m currently trying to get a dpdk based application running, but I’m a bit unsure about the following error:

 

EAL: Error - exiting with code: 1

  Cause: rte_eth_rx_queue_setup:err=-22, port=0

 

 

I already compiled dpdk with debug option on and the changed default as suggested in this thread:

 

http://mails.dpdk.org/archives/users/2017-February/001524.html

 

But I’m not getting further. This is the current debug output:

EAL: Error - exiting with code: 1

I’m currently not sure if the problem is related to my dpdk setup or the code where this error is happening:

 

    /* Init RX queues */

    for (lcore_id = 0; lcore_id < RTE_MAX_LCORE; lcore_id++) {

        if (rte_lcore_is_enabled(lcore_id) == 0)

            continue;

        qconf = &lcore_conf[lcore_id];  

        for(queue = 0; queue < qconf->n_rx_queue; ++queue) {

            portid = qconf->rx_queue_list[queue].port_id;

            queueid = qconf->rx_queue_list[queue].queue_id;

 

            printf("setting up rx queue on port %u, queue %u\n", portid, queueid);  

            ret = rte_eth_rx_queue_setup(portid, queueid, nb_rxd,

                             rte_eth_dev_socket_id(portid),

                         NULL,

                         dpdklatency_pktmbuf_pool);

            if (ret < 0)

                rte_exit(EXIT_FAILURE, "rte_eth_rx_queue_setup:err=%d, port=%u\n",

                      ret, (unsigned) portid);

        }

    }

 

Happy about any clue!

 

Thanks for your support,

Matt
