Re: [dpdk-users] SR-IOV problem with dpdk drivers

+dev-dpdk can help here..

I have removed SR-IOV and made those interfaces as PIC-passthrough and that
is working without any issues.
So, Yes! this could be problem with virtual function driver(i40evf).

Thanks

Linux driver works, DPDK older version works but not dpdk 17.05.
Then it seems the dpdk driver of 17.05 has some issues to work with vmware
hypervisors.

Thanks Raju..

These SR-IOV interfaces are reachable with linux drivers and also i have
verified with dpdk 2.2.0, which is running without any issues.
But when i bring in dpdk17.05, it failed to come up with above mentioned
error messages.

please help me if, is it known issue with new SR-IOV drivers? or did i
miss something?

hello Sakthivel,
Can you try if on this VM, the kernel can see the interfaces and ping
works with those interfaces?
Secondly did you try with older version of DPDK ?

I’m not an expert, but my guess is that your PF is running a very
different version of the i40e driver, and because of this the two

communicate. I personally have never seen this before. Perhaps google

has?

could someone pls help where i have missed?

ERROR:

Error: bind failed for 0000:0b:00.0 - Cannot open

Is the igb_uio kernel module loaded? lsmod should say. If not, run
'modprobe igb_uio', then try again.
