I have written a PMD for my non-pci based ethernet device. My device is
queue based (RX and TX queues).
testpmd application is running successfully and I am able to transmit and
receive traffic at line rate through my ethernet interface.
my testpmd execution command:
# ./_install/bin/testpmd -c ff -n 4 --vdev=uio_my_eth1
Now I need to export my device as a kernel network interface so that it
shows up using ifconfig command, I believe KNI driver and app can help
I inserted rte_kni.ko module in my kernel and executed kni appliation
# ./app/kni --vdev=uio_my_eth1 -- -p 0x1 -P --config="(0,1,2)"
At this point kni app. is crashing with seg. fault.
Can I use KNI module and application for my non-pci based vdev or only DPDK
supported NICs will work with them ?
Do I need to build and load vhost kernel module too ?
