Hi All,
Trying to test E810 Sr-IOV based nic card with 20.11.3 dpdk. I am running the host kernel driver and only the VF is attached to the VM where I am running dpdk. But when I attaching the VF to the testpmd it is throwing the below error. Is there are way to move forward here ?

Hi Wu,
Thanks for the update. I got rid of the vfio-pci probe issue by enabling "modprobe vfio enable_unsafe_noiommu_mode=1". This was required as I am trying inside a VM where VT-d is not enabled. Now once I bind the interfaces( VF) to the vfio-pci instead of uio_pci_generic , the links are coming up fine and I am able to rx/tx packets out of the VF. Thanks once again for the quick help on this.
Just one follow up question. Are we saying we cannot use uio_pci_generic module for the E810 VFs ? is it a bug, do we have any fixes for the same already upstreamed ?

Regards,
Souvik
