Hi All,

I'm facing the following issue when testing testpmd application with DPDK-1.8.0.

EAL: PCI device 0000:03:00.0 on NUMA socket -1
EAL:   probe driver: 15ad:7b0 rte_vmxnet3_pmd
EAL:   0000:03:00.0 not managed by UIO driver, skipping
EAL: PCI device 0000:0b:00.0 on NUMA socket -1
EAL:   probe driver: 15ad:7b0 rte_vmxnet3_pmd
EAL:   0000:0b:00.0 not managed by UIO driver, skipping
EAL: PCI device 0000:13:00.0 on NUMA socket -1
EAL:   probe driver: 15ad:7b0 rte_vmxnet3_pmd
EAL:   0000:13:00.0 not managed by UIO driver, skipping
EAL: PCI device 0000:1b:00.0 on NUMA socket -1
EAL:   probe driver: 15ad:7b0 rte_vmxnet3_pmd
EAL:   0000:1b:00.0 not managed by UIO driver, skipping
EAL: Error - exiting with code: 1
  Cause: No probed ethernet device

Please let me know, what could be the issue.

FYI:
Igb_uio and rte_kni ko modules are inserted successfully.


Regards,
Varun

After you load the uio driver, you still need to bind some NIC devices to use
it, otherwise DPDK will ignore those devices as being used by the kernel.
The script "dpdk_nic_bind.py" in the tools directory can help with the binding
and unbinding to the different drivers.

Hi Bruce,

Thanks for your reply.

I used dpdk_nic_bind.py script to bind igb_uio driver for the specific NIC ports. 

[root@SSBC swe]# ./ dpdk_nic_bind.py  --status

Network devices using IGB_UIO driver
====================================
0000:03:00.0 'VMXNET3 Ethernet Controller' drv=igb_uio unused=vmxnet3
0000:13:00.0 'VMXNET3 Ethernet Controller' drv=igb_uio unused=vmxnet3
0000:1b:00.0 'VMXNET3 Ethernet Controller' drv=igb_uio unused=vmxnet3

Network devices using kernel driver
===================================
0000:0b:00.0 'VMXNET3 Ethernet Controller' if=ha0 drv=vmxnet3 unused=igb_uio

When we ported to DPDK1.7.0, we didn't face this kind of issues.

When I googled, found similar problem. But didn't get any solution from that.
http://patchwork.dpdk.org/ml/archives/dev/2014-February/001437.html

Please give some directions to resolve this issue.

Varun
