I built the current version of DPDK directly from dpdk.org after I
installed the current OFED Mellanox driver set:
* MLNX_OFED_LINUX-5.5-1.0.3.2-ubuntu20.04-x86_64.iso
with ./install --dpdk
I am using a Mellanox Technologies MT27710 Family [ConnectX-4 Lx] which is
Ethernet only; there is no IB mode for this NIC. This is a MT_2420110034
board. However, when I run dpdk-testpmd I see "No Verbs device matches PCI
device 0000:01:00.1, are kernel drivers loaded?"
EAL: Detected CPU lcores: 16
EAL: Detected NUMA nodes: 1
EAL: Detected static linkage of DPDK
EAL: Selected IOVA mode 'PA'
EAL: No free 2048 kB hugepages reported on node 0
EAL: VFIO support initialized
EAL: Probe PCI driver: mlx5_pci (15b3:1015) device: 0000:01:00.1 (socket 0)
mlx5_common: No Verbs device matches PCI device 0000:01:00.1, are kernel
drivers loaded?
mlx5_common: Verbs device not found: 01:00.1
mlx5_common: Failed to initialize device context.
EAL: Requested device 0000:01:00.1 cannot be used
EAL: Bus (pci) probe failed.
As far as I can see all the kernel modules are loaded:
