[USRP-users] Getting DPDK to work

So now I'm so close to working with DPDK, seemingly. Every time I fix one thing there's another.

./rx_samples_to_file --args="use_dpdk=1,addr=192.168.30.2,addr2=192.168.40.2" --duration 0.01

Just searching online it seemed like most people recommended reflashing the fpga, which I did. No change.

FYI the problem ended up being that the UHD configuration file requires an underscore with [use_dpdk=1] (instead of a dash, like everything else in the file uses), and also that dpdk-io-cpu=x is required instead of dpdk-lcore to initialize the adapters. Thanks for the help.

Of course now rx_samples_to_file segfaults in rte_eth_rx_queue_setup, but at least it's forward movement.

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.
