            Bug ID: 13
           Summary: Cannot initialize Intel XL710 40G interface
           Product: DPDK
           Version: 17.11
          Hardware: x86
                OS: Linux
            Status: CONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: gabor.sandor.enyedi@ericsson.com
  Target Milestone: ---

We have an AMD Threadripper 1950X, w/ 2 NUMA nodes. I cannot initialize our
XL710 cards in the slots belonging to NUMA node #0. In slots belonging to NUMA
node #1 it seems to be OK. I get this at initialization:

EAL: Detected 32 lcore(s)
EAL: Debug dataplane logs available - lower performance
EAL: Probing VFIO support...
EAL: PCI device 0000:09:00.0 on NUMA socket 0
EAL:   probe driver: 8086:1583 net_i40e
eth_i40e_dev_init(): Failed to init adminq: -54
EAL: Requested device 0000:09:00.0 cannot be used
EAL: PCI device 0000:09:00.1 on NUMA socket 0
EAL:   probe driver: 8086:1583 net_i40e
eth_i40e_dev_init(): Failed to init adminq: -54
EAL: Requested device 0000:09:00.1 cannot be used
EAL: PCI device 0000:41:00.0 on NUMA socket 1
EAL:   probe driver: 8086:1583 net_i40e
EAL: PCI device 0000:41:00.1 on NUMA socket 1
EAL:   probe driver: 8086:1583 net_i40e

I.e. the 2 ports in the card belonging to NUMA #1 was initialized correctly
(41:00.x), but the other two fails.
This machine can "hide" its NUMA behavior by setting so in BIOS (i.e. in this
case I see one single NUMA node w/ 16 cores), but this feature does not help
eiter. I get the same both when have 1 or 2 XL710 cards in the box. I get the
same with the latest DPDK from git. Using the kernel, everything seems to be
OK.
What tests can I do to help finding the bug?
