There is codes as below in examples/l2fwd/main.c and I think
rte_eth_dev_socket_id(portid)
always returns -1(SOCKET_ID_ANY) since there is no association code between
port and
lcore in the example codes. (i.e. I need to find a matching lcore from
lcore_queue_conf[] with portid
and call rte_lcore_to_socket_id(lcore_id).)
/* init one RX queue */
fflush(stdout);
ret = rte_eth_rx_queue_setup(portid, 0, nb_rxd,
rte_eth_dev_socket_id(portid),
NULL,
l2fwd_pktmbuf_pool);
if (ret < 0)
rte_exit(EXIT_FAILURE, "rte_eth_rx_queue_setup:err=%d,
port=%u\n",
ret, (unsigned) portid);
It works fine even though memory is allocated in different NUMA node. But I
wonder there is
a DPDK API that associates inlcore to port internally thus
rte_eth_devices[portid].pci_dev->numa_node
contains proper node.
