Ferruh,

On my fedora23, I don't have igb_uio

# modprobe igb_uio
modprobe: FATAL: Module igb_uio not found in directory
/lib/modules/4.4.6-300.fc23.x86_64


I am trying to bind to uio_pci_generic module

Hi,

I am having an issue with binding a nic of type 82545EM to dpdk. I am
using
quoted
a
fedoracore23 VM on MAC with VMFusion.

./dpdk_nic_bind.py -b uio_pci_generic 0000:02:02.0
Error: bind failed for 0000:02:02.0 - Cannot bind to driver
uio_pci_generic
quoted
Error: unbind failed for 0000:02:02.0 - Cannot open
/sys/bus/pci/drivers//unbind

it is unbound from e1000, repeating the command:

./dpdk_nic_bind.py -b uio_pci_generic 0000:02:02.0
Error: bind failed for 0000:02:02.0 - Cannot bind to driver
uio_pci_generic

I repeated the same test on a ubuntu vm running on Virtualbox with
NIC type 82450EM

In this case, the device is able to bind successfully to uio_pci_generic
driver.

There is a igb_uio module that present. The device cannot be bound to the
igb_uio
driver.
Hi Al,

You are trying to bind to the driver "uio_pci_generic" not to the
"igb_uio", is it typo? If not, can you please double check if
"uio_pci_generic" module inserted.
Or bind device to "igb_uio":
"./dpdk_nic_bind.py -b igb_uio 0000:02:02.0"

Regards,
ferruh
