Hi Nishant,

Thanks for your suggestions but even it did not work, In the meanwhile, I will see what can I do from my side. Any other suggestions from the community is also really helpful at this time

As par error message, it seems error lies in validation. But it seems right
Can you try to run the app without kthread option. if you haven't tried that. just to pin point the problem.

./kni -c 0x0f -n 2 -- -P -p 0x3 --config="(0,2,3),(1,0,1)"
while executing, load kni module with single mode option.

Hi Guys,

I am trying to run the KNI sample application according to the DPDK documentation which is given below.

http://dpdk.org/doc/guides/sample_app_ug/kernel_nic_interface.html#running-the-application

I am not able to run the app successfully,

I don't have this problem with any other DPDK example application and I also verified that I have loaded the *.ko files properly (rte_kni.ko, igb_uio.ko, etc.)

I have also loaded rte_kni.ko with kthread_mode single/multiple but both results are same.

I am using two 1G ports in this example which are port 0 and port 1 and it has been attached to DPDK through (dpdk_nic_bind.py) script.

Output of the dpdk_nic_bind.py

we are using dpdk v2.1 at this moment, any suggestions to make this work would be a great help for me.

Please let me know if you need more info on this

Thanks a lot in advance!

Thanks
Jaffar
