[AMD Official Use Only - General] Hi Balakrishnan K,
With respect to error (shared below), I believe this is expected ``` > [ 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? ``` Please refer https://doc.dpdk.org/guides/nics/ixgbe.html, section `30.4.5. X550 does not support legacy interrupt mode`. With respect to the original error (shared below) ``` > I am trying to bind VF interface to dpdk using dpdk-devbind.py. Unable to > bind getting error ?. ``` As per the IXGBE PMD documentation, one has to follow ``` Step-1: insmod ixgbe.ko MDD=0,0 Step-2: PF port is Kernel driver Step-3: create VF Step-4: modprobe vfio `` ``nointxmask=1 Step-5: then bind the VF devices with `vfio-pci` ``` For your question ` cannot bind to driver uio_pci_generic?`, I humbly request to check ` The errata is the item #22 from X550 spec update` in section ` 30.4.5.1. Description`. Then check with Intel Network PMD maintainer if this can be fixed. Note: please do let us know if vfio-pci or igb_uio works for VF devices under X540 (as I do not have similar card I unable to test it out for you). > -----Original Message----- > From: [email protected] <[email protected]> > Sent: Thursday, September 15, 2022 12:42 PM > To: [email protected] > Subject: users Digest, Vol 356, Issue 6 > > Caution: This message originated from an External Source.
