Hi All, Previously, I had DPDK-19.11 working fine on my server system, which runs on Ubuntu 18.04. Have a 4-Port 10 Gigabit Network card, with ports bound to use VFIO-PCI driver. But had to move to DPDK-20.11, and running into issues.
I installed on DPDK-20.11 on the server to /usr/local. And did binding of ports using the dpdk-devbind script to use VFIO-PCI driver. But when running DPDK sample application such as-> dpdk-20.11/examples/packet_ordering, noticed DPDK is NOT able to detect any available ports. Getting error-> Cause: Error: no ethernet ports detected Also when I pass parameter to block certain interfaces(Bus:Device.Function) on a NIC, EAL throws an Error-> EAL: failed to parse device "0000:31.00.0" On the same system, using the same 10 Gigbit Network card, DPDK sample applications were working fine with older version of DPDK->19.11 Below, I have the output of commands: ~/dpdk-20.11$ sudo ./usertools/dpdk-devbind.py --status Network devices using DPDK-compatible driver ============================================ 0000:31:00.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' drv=vfio-pci unused=i40e 0000:31:00.1 'Ethernet Controller X710 for 10GbE SFP+ 1572' drv=vfio-pci unused=i40e 0000:31:00.2 'Ethernet Controller X710 for 10GbE SFP+ 1572' drv=vfio-pci unused=i40e 0000:31:00.3 'Ethernet Controller X710 for 10GbE SFP+ 1572' drv=vfio-pci unused=i40e Network devices using kernel driver =================================== 0000:01:00.0 'I210 Gigabit Network Connection 1533' if=enp1s0 drv=igb unused=vfio-pci *Active* 0000:17:00.0 'Ethernet Controller 10G X550T 1563' if=ens6f0 drv=ixgbe unused=vfio-pci *Active* 0000:17:00.1 'Ethernet Controller 10G X550T 1563' if=ens6f1 drv=ixgbe unused=vfio-pci *Active* cat /proc/meminfo | grep -i huge AnonHugePages: 8192 kB ShmemHugePages: 0 kB HugePages_Total: 2048 HugePages_Free: 2048 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB :~/dpdk-20.11/examples/packet_ordering$ sudo ./build/packet_ordering-shared -l 4-6 -n 2 --log-level 7 -m 1024 --file-prefix packet_order -- -p 0xf --disable-reorder EAL: Detected 72 lcore(s) EAL: Detected 2 NUMA nodes EAL: Multi-process socket /var/run/dpdk/packet_order/mp_socket EAL: Selected IOVA mode 'VA' EAL: No available hugepages reported in hugepages-1048576kB EAL: Probing VFIO support...
