Thanks for the update. Sounds like you're already using DPDK 17.11?
What about Mellanox driver level? Is the failure the same as you
originally reported?
>From the reported error:
pktio/dpdk.c:1538:dpdk_start():Queue setup failed: err=-12, port=0
odp_l2fwd.c:1671:main():Error: unable to start 0
This is a DPDK PMD driver error reported by rte_eth_rx_queue_setup().
In the Mellanox PMD (drivers/net/mlx5/mlx5_rxq.c) this is the
mlx5_rx_queue_setup() routine. The relevant code seems to be this:
if (rxq != NULL) {
DEBUG("%p: reusing already allocated queue index %u (%p)",
(void *)dev, idx, (void *)rxq);
if (priv->started) {
priv_unlock(priv);
return -EEXIST;
}
(*priv->rxqs)[idx] = NULL;
rxq_cleanup(rxq_ctrl);
/* Resize if rxq size is changed. */
if (rxq_ctrl->rxq.elts_n != log2above(desc)) {
rxq_ctrl = rte_realloc(rxq_ctrl,
sizeof(*rxq_ctrl) +
(desc + desc_pad) *
sizeof(struct rte_mbuf *),
RTE_CACHE_LINE_SIZE);
if (!rxq_ctrl) {
ERROR("%p: unable to reallocate queue index %u",
(void *)dev, idx);
priv_unlock(priv);
return -ENOMEM;
}
}
} else {
rxq_ctrl = rte_calloc_socket("RXQ", 1, sizeof(*rxq_ctrl) +
(desc + desc_pad) *
sizeof(struct rte_mbuf *),
0, socket);
if (rxq_ctrl == NULL) {
ERROR("%p: unable to allocate queue index %u",
(void *)dev, idx);
priv_unlock(priv);
return -ENOMEM;
}
}
The reported -12 error code is -ENOMEM so I'd say the issue is some
sort of memory allocation failure.
