[dpdk-users] DPDK 20.05 MLX5 'no Verbs device matches PCI device , are kernel drivers loaded'

["baoli.wnag" <iamwangmali@163.com>]

Hi,




I am trying to test the mlx5 performance on ubuntu 16.04, and when I run the testpmd with mlx nic,

Some error happened.




EAL: Probe PCI driver: net_mlx5 (15b3:1018) device: 0000:af:02.3 (socket 1)

net_mlx5: mlx5.c:3322: mlx5_pci_probe(): no Verbs device matches PCI device 0000:af:02.3, are kernel drivers loaded?

EAL: Requested device 0000:af:02.3 cannot be used

EAL: Probe PCI driver: net_mlx5 (15b3:1018) device: 0000:af:02.4 (socket 1)

net_mlx5: mlx5.c:3322: mlx5_pci_probe(): no Verbs device matches PCI device 0000:af:02.4, are kernel drivers loaded?

EAL: Requested device 0000:af:02.4 cannot be used

EAL: Bus (pci) probe failed.




And which happened after I manually installed the packages which command ‘mlnxofedinstall --upstream-libs –dpdk’ showed.




MLNX_OFED_LINUX-5.1-2.3.7.1-ubuntu16.04-x86_64# ./mlnxofedinstall --upstream-libs --dpdk

Below is the list of MLNX_OFED_LINUX packages that you have chosen

(some may have been added by the installer due to package dependencies):




ofed-scripts

mstflint

mlnx-ofed-kernel-utils

mlnx-ofed-kernel-dkms

rdma-core

libibverbs1

ibverbs-utils

ibverbs-providers

libibverbs-dev

librdmacm1

rdmacm-utils

librdmacm-dev

libibumad3

ibacm




This program will install the MLNX_OFED_LINUX package on your machine.

Note that all other Mellanox, OEM, OFED, RDMA or Distribution IB packages will be removed.

Those packages are removed due to conflicts with MLNX_OFED_LINUX, do not reinstall them.




Do you want to continue?[y/N]:y




Checking SW Requirements...

One or more required packages for installing MLNX_OFED_LINUX are missing.

Attempting to install the following missing packages:

graphviz chrpath libltdl-dev dpatch autoconf m4 quilt swig automake debhelper autotools-dev

Failed command: apt-get install -y graphviz chrpath libltdl-dev dpatch autoconf m4 quilt swig automake debhelper autotools-dev




I installed the packages above showed successfully except the package ibacm,

As when I tried to install this package, an error happened,




MLNX_OFED_LINUX-5.1-2.3.7.1-ubuntu16.04-x86_64/DEBS# dpkg -i ibacm_51mlnx1-1.51237_amd64.deb

And the error info is like below:

Do you have any idea about this?




Thanks in advance.
