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.

Regards,

Bala
