Bug ID: 178
Summary: l2fwd application does not work with option '-q'
Product: DPDK
Version: 18.11
Hardware: All
OS: All
Status: CONFIRMED
Severity: normal
Priority: Normal
Component: examples
Assignee: [email protected]
Reporter: [email protected]Target Milestone: ---
As per
usage description: '-q NQ: number of queue (=ports) per lcore (default is 1)'
documentation description: URL
https://doc.dpdk.org/guides/sample_app_ug/l2_forward_real_virtual.html
To run the application in linuxapp environment with 4 lcores, 16 ports and 8 RX queues per lcore and MAC address updating enabled, issue the command: $ ./build/l2fwd -l 0-3 -n 4 -- -q 8 -p ffff
issue: I am only able to fetch 1 RX queue per port
Checking the code base I find:
1) lcore are mapped to lcores by
/* get the lcore_id for this port */
while (rte_lcore_is_enabled(rx_lcore_id) == 0 ||
lcore_queue_conf[rx_lcore_id].n_rx_port ==
l2fwd_rx_queue_per_lcore) {
rx_lcore_id++;
if (rx_lcore_id >= RTE_MAX_LCORE)
rte_exit(EXIT_FAILURE, "Not enough cores\n");
}2) but RX queue is setup it is done for 1 rx queue per port
ret = rte_eth_rx_queue_setup(portid, 0, nb_rxd,
rte_eth_dev_socket_id(portid),
&rxq_conf,
l2fwd_pktmbuf_pool);what is that I am missing to make this work for 1 port with 4 rx queues?
