Hi again Reshma
I worked on testpmd and below is the output of testpmd command in dpdk-setup.sh
script (number 28 in the list) :
Option: 28

Example: to execute app on cores 0 to 7, enter 0xff
bitmask: 0xff

[Reshma 1]:
After above logs you should be seeing logs similar to below ones.
PMD: Initializing pmd_pcap for eth_pcap_rx_0
PMD: Creating pcap-backed ethdev on numa socket 0
Port 2 MAC: 00 00 00 01 02 03
Since you are not seeing, I guess dpdk-pdump tool might have got stuck in the
code somewhere.
Can you just add some debug prints after the below if condition in the file
app/pdump/main.c, there are 3 such if conditions, so add prints at all 3
places.
Compile the dpdk-pdump again , run and give me the startup logs.
if (rte_eth_dev_attach(vdev_args,
&portid) < 0) {
cleanup_rings();
rte_exit(EXIT_FAILURE,
"vdev creation failed:"
"%s:%d\n", __func__, __LINE__);
}
[Reshma 2]:
Can you provide the output of ?rpm -qa | grep pcap?
[Reshma 3]:
Can you give the output of ?grep CONFIG_RTE_LIBRTE_PMD_PCAP config/common_base?
Thanks,
Reshma
I have no idea what is the problem!
