Subject: dpdk-test does not work
To: USRP-users@lists.ettus.com <usrp-users@lists.ettus.com>
Dear all,
We have a USRP X310 setup and we are trying to make the
UHD_3.15.0.0-0-g4e06022c driver work. I have added a file under
/etc/uhd/uhd.conf and it is attached to this email.
I am not sure about the dpdk-mac and dpdk-ipv4 addresses, what are they
used for?
I am trying to make the dpdk-test work but I am experiencing problems with
setting of ipv4.

What should be the uhd-dpdk arguments for this to run? It seems like it
does not even read the uhd.conf file.
I am using DPDK dpdk-stable-17.11.9. I have also programmed my SFP+
interface via dpdk-devbind.py as shown below.

sudo ./dpdk-devbind.py -s

;When present in device args, use_dpdk indicates you want DPDK to take over the
UDP transports
;The value here represents a config, so you could have another section labeled
use_dpdk=myconf
;instead and swap between them
[use_dpdk=1]
;dpdk_mtu is the NIC's MTU setting
;This is separate from MPM's maximum packet size
dpdk-mtu=9000
;dpdk_driver is the -d flag for the DPDK EAL. If DPDK doesn't pick up the
driver for your NIC
;automatically, you may need this argument to point it to the folder where it
can find the drivers
;Note that DPDK will attempt to load _everything_ in that folder as a driver,
so you may want to
;create a separate folder with symlinks to the librte_pmd_* and
librte_mempool_* libraries.
dpdk-driver=/home/ulak-gnb/ulak/dpdk-stable-17.11.9/x86_64-native-linuxapp-gcc/lib/pmds
;dpdk_corelist is the -l flag for the DPDK EAL. See more at the link
;
https://doc.dpdk.org/guides-18.11/linux_gsg/build_sample_apps.html#running-a-sample-application
dpdk-corelist=5,6
;dpdk_num_mbufs is the total number of packet buffers allocated
;to each direction's packet buffer pool
;This will be multiplied by the number of NICs, but NICs on the same
;CPU socket share a pool.
dpdk-num-mbufs=4095
;dpdk_mbuf_cache_size is the number of buffers to cache for a CPU
;The cache reduces the interaction with the global pool
dpdk-mbuf-cache_size=315
[dpdk-mac=ac:1f:6b:78:5a:09]
;dpdk_lcore selects the lcore that this NIC's driver will run on
;Multiple NICs may occupy one lcore, but the I/O thread will completely
;consume that lcore's CPU. Also, 0 is reserved for the master thread (i.e.
;the initial UHD thread that calls init() for DPDK). Attempting to
;use it as an I/O thread will only result in hanging.
;Note also that by default, the lcore ID will be the same as the CPU ID.
dpdk-io-cpu = 5
;dpdk_ipv4 specifies the IPv4 address, and both the address and
;subnet mask are required (and in this format!). DPDK uses the
;netmask to create a basic routing table. Routing to other networks
;(i.e. via gateways) is not permitted.
dpdk-ipv4 = 10.10.1.5/24
;dpdk_num_desc is the number of descriptors in each DMA ring.
;Must be a power of 2.
;dpdk_num_desc=4096
