I’ve got an X310, UHD 3.15.LTS (compiled with DPDK support), DPDK
17.11 on Red Hat. I feel like things are 95% of the way there, but I
can’t get UHD to work with DPDK.
Long story short, I’m getting the error “EAL: Please set IPv4 address
for port 0 before opening socket”. I wonder if it’s not reading my uhd
conf file.
Before dpdk-devbind, the X310 has two IP addresses that are pingable
(192.168.30.2 and 40.2) from my NICs:
enp13s0f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9001
inet 192.168.30.99 netmask 255.255.255.0 broadcast
192.168.30.255
ether aa:bb:cc:dd:ee:01 txqueuelen 1000 (Ethernet)
enp13s0f1: flags=4099<UP,BROADCAST,MULTICAST> mtu 9001
inet 192.168.40.99 netmask 255.255.255.0 broadcast
192.168.40.255
ether aa:bb:cc:dd:ee:02 txqueuelen 1000 (Ethernet)
After running dpdk-devbind:
Network devices using DPDK-compatible driver
============================================
0000:0d:00.0 '82599ES 10-Gigabit SFI/SFP+ Network Connection 10fb'
drv=igb_uio unused=vfio-pci,uio_pci_generic
0000:0d:00.1 '82599ES 10-Gigabit SFI/SFP+ Network Connection 10fb'
drv=igb_uio unused=vfio-pci,uio_pci_generic
I have a configuration file:
[use-dpdk=1]
dpdk-mtu=9000
dpdk-corelist=0,1
dpdk-num-mbufs=4096
dpdk-mbuf-cache-size=64
[dpdk-mac=aa:bb:cc:dd:ee:01]
dpdk-lcore = 1
dpdk-ipv4 = 192.168.30.1/24
dpdk-num-desc=4096
[dpdk-mac=aa:bb:cd:dd:ee:02]
dpdk-lcore = 0
dpdk-ipv4 = 192.168.40.1/24
Check for syntax errors in the conf file?
I can't remember whether spaces are allowed around "=" in those config
files or not.
