Hello, I need help to manage packet using dpdk under xeon intel chip. When I launch testpmd, I'm wondering if output traces below are blocking to check bandwith: >./testpmd -l 0-3 -n 4 -- -i --portmask=0x1 --nb-cores=2 EAL: Detected 8 lcore(s) EAL: 1024 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for that size EAL: Probing VFIO support...

Port 0 Link Up - speed 0 Mbps - full-duplex Port 1 Link Up - speed 0 Mbps - full-duplex On one side, traces show that there is NUMA, speed and hupepage issue. Have you a idea ? Thank you
Looks like only speed issue, how do u know NUMA and hugepage issue? "1024 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for that size" didn't mean huge page issue, the app will check default folder for the huge page mounted folder. If huge page has issue, you can't run up the app. As to numa, since you are using lcore 1-3, then it will use socket 0 for memory allocation and core allocation. How about the fm10k device firmware and dpdk version?
fm10k can be used in PICeX8 or X4 mode, the speed is ~50Gbps per Gen3 x8 PCIe interface, and ~25Gbps per x4 interface. And the speed can be restricted by TestPoint (Switch manager). Currently the driver leaves 'speed' field as 0 because it's not aware of the x8 or x4 configuration.
nounoussma@hotmail.com, Are you satisfied with the explanation? Do you anything need more on this issue? If not, can you close it? Thanks Ajit
