[dpdk-users] [ TX-ONLY mode ] No packet count with Testpmd application

Hi Members ,

I am trying to run the testpmd command on a x86_64 machine .
Have shared the log's of
     - Command testpmd
     - Command devbind
     - Steps i followed to get the dpdk source code compiled on host

 ~ : sudo dpdk-testpmd -l 0-3 -n 4 -- -i --nb-cores=2
EAL: Detected 32 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: Detected static linkage of DPDK

Done.


B) I have the the device binding
     #  dpdk-devbind.py -s
         Network devices using DPDK-compatible driver
         ============================================
         0000:c6:00.1 'BCM57416 NetXtreme-E Dual-Media 10G RDMA Ethernet
Controller 16d8' drv=uio_pci_generic unused=bnxt_en,vfio-pci

C) The dpdk was compiled using below step:
         git clone https://dpdk.org/git/dpdk
         cd dpdk/
         pip3 install meson
         pip3 install pyelftools
         pip3 install ninja
         meson -Dexamples=all build
         ninja -C build
         cd build
         ninja install
         ldconfig
         mkdir -p /dev/hugepages
         mountpoint -q /dev/hugepages || mount -t hugetlbfs nodev
/dev/hugepages
         bash -c 'echo 2048 >
/sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages'

Can a senior member please help me as I am learning things here .
And getting working setup is very important for someone like me who is
starting new here

Thanks ,

Hi Members ,
Debugging further what i could understand is that DPDK requires drivers
example: igb_uio.ko

Can the team please help me from where do I get these drivers?
I am trying to get dpdk working on custom buildroot sdk

 Does testpmd require any specific driver?
currently i am binding free ethernet interface to dpdk , but cant see
traffic

So i am considering that  some kernel dependency / drivers are required tp
get testpmd working

Any pointer will be helpful as i am very new here

Thanks
Ashish
