I have a Wolf Pass 2600WFT Server where I am trying to load a DPDK-assisted vSwitch as I do on the Wild Cat Pass.
But DPDK fails to load because the Ethernet port is on PCIe domain 10000, instead of the normal 0000.
Is there some BIOS setting or update to make the domain for this Fortville NIC to be enumerated in domain 0000 ?
# ovs-dpdk -c 0x5 -n 4 -r 2 --socket-mem 1024,1024 --huge-dir /mnt/huge-1048576kB --file-prefix vs --proc-type primary -w 10000:01:00.0
DPDK failed to allocate requested resources...

Hi,
I found the problem could be worked around by moving my NIC to a different PCIe slot.
However it is not clear which slots would work and which slots would not work.
So I request that Intel do the following, if possible:
1. Document which PCIe slots generate a 32 bit PCIe domain and which generate a 16 bit PCIe domain
AND/OR
2. Change the firmware/BIOS so that only a 16 bit PCIe domain is generated. It seems to me that 65,536 PCIe domains should be "quite sufficient".
16 or 32 bit PCIe domain space generation could be a setting in the BIOS, with 16 bit being the default.
Thanks,
Gary

Hello Gary,
Can you please put the NIC in the other CPU slot. Seems like it is currently in CPU 2 slot. Connecting that NIC to CPU 1 slot will help to give the number as you desire.
Best regards,
Sergio S.
