Hi, I want to run & test DPDK application for my board OD1000 (armv8a 64-bit) and I have CentOS 7 installed on my board.I have compiled DPDK application [root@localhost build]# uname -r4.11.0-45.6.1.el7a.aarch64 I have successfully compiled the dpdk application & all examples applications as well. But when I tried to run "l2fwd" sample test I'm getting following error. [root@localhost build]# ./l2fwd -c 0x2 -n 1 -- -p 0x1 -q 1EAL: Detected 4 lcore(s)EAL: 1024 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for that sizeEAL: Probing VFIO support...EAL: VFIO support initializedMAC updating enabledEAL: Error - exiting with code: 1 Cause: No Ethernet ports - bye Here is status of my supported cards.[root@localhost dpdk-stable-17.11.1]# ./usertools/dpdk-devbind.py --status Network devices using DPDK-compatible driver============================================0000:02:00.0 'Yukon Optima 88E8059 [PCIe Gigabit Ethernet Controller with AVB] 4381' drv=igb_uio unused=sky2,vfio-pci,uio_pci_generic Network devices using kernel driver===================================<none> Other Network devices=====================<none> Crypto devices using DPDK-compatible driver===========================================<none> Crypto devices using kernel driver==================================<none> Other Crypto devices====================<none> Eventdev devices using DPDK-compatible driver=============================================<none> Eventdev devices using kernel driver====================================<none> Other Eventdev devices======================<none> Mempool devices using DPDK-compatible driver============================================<none> Mempool devices using kernel driver===================================<none> Other Mempool devices=====================<none>[root@localhost dpdk-stable-17.11.1]# To work around I have tried following commands but they are too giving me errors as well. ./l2fwd --vdev= igb_uio,iface=eth0 --l 0-3 -n 4 -- -q 8 -p ffff ./l2fwd --vdev= igb_uio,iface=enp2s0 --l 0-3 -n 4 -- -q 8 -p ffff......

Yukon Optima 88E8059 [PCIe Gigabit Ethernet Controller with AVB][root@localhost build]# My doubt is to check whether DPDK have the support for this card are not ?And if it is supported. please suggest me your inputs to resolve this problem or let me know if i'm missing anything. Apart from that I have found that my Ethernet device named as "enp2s0" before running " ./usertools/dpdk-devbind.py --bind"igb_uio" command. Note: I'm new to this community & learning this platform so please forgive me if I have added something wrong. Regards,Anupam Kumar
