how to bind VF interface into dpdk

[Balakrishnan K]

Hi Sathish,
  Thanks for the input .
Checked the dmesg  below are the error msg.
[ 1394.034137] uio_pci_generic 0000:06:00.0: No IRQ assigned to device: no support for interrupts?
[ 1394.037596] uio_pci_generic 0000:06:00.0: No IRQ assigned to device: no support for interrupts?
[ 1421.498627] uio_pci_generic 0000:06:00.0: No IRQ assigned to device: no support for interrupts?
[ 1421.500976] uio_pci_generic 0000:06:00.0: No IRQ assigned to device: no support for interrupts?

Is any BIOS setting needed to resolve the issue.


Regards,
Bala

Hi,

 I would also check dmesg logs for any indication or warning. I had an issue like that and it turned out to be a BIOS setting related to some nic shared memory.

Hi All,
    I am trying to bind VF interface to dpdk using dpdk-devbind.py.
Unable to bind getting error “cannot bind to driver uio_pci_generic”.
Steps followed:
1.modprobe uio_pci_generic
2. dpdk-devbind.py -b uio_pci_generic 0000:05:00.0

Also tried with vfio-pci driver not succeeded.
Attaching the dpdk-devbind -s output and the error which I got.

Am I missing something could any one please help on this.
