[AMD Official Use Only - AMD Internal Distribution Only]


Hi Jasvinder,

 

I was facing similar issue with Cx-7 and it appears that the issue is related to the network namespace.

By configuring the Pod/container to use the "host's network namespace," the issue is effectively resolved.

----

  spec:

      nodeSelector:

        "feature.node.kubernetes.io/test-node": "true"

      hostNetwork: true

      containers:

Thanks & Regards,

Hi Folks,

 

I am trying to run dpdk-testpmd in a container with NVIDIA ConnectX-7 NIC card on the system and facing issue described below. Details on the system setup are as follow-

 

Host Configuration for OFED and CX7:

Nvidia CX7 is configured to use Ethernet as opposed to InfiniBand with the following steps:

 

OFED driver installation:

./mlnxofedinstall --without-dkms --add-kernel-support --kernel 6.8.0-51-generic --without-fw-update --force

 

Configuration:

 

mlxconfig -d /dev/mst/mt4129_pciconf0  set LINK_TYPE_P1=2

mlxconfig -d /dev/mst/mt4129_pciconf1  set LINK_TYPE_P1=2

 

SRIOV has been also enabled on the NIC.

 

The above configuration resulted in successfully deploying dpdk-testpmd on virtual functions on the host.

 

Container Configuration for OFED:

Ubuntu 22.04 used within container.

 

# Install mlnx OFED Drivers

RUN wget https://www.mellanox.com/downloads/ofed/MLNX_OFED-24.07-0.6.1.0/MLNX_OFED_LINUX-24.07-0.6.1.0-ubuntu24.04-x86_64.tgz \

       && tar -xvf MLNX_OFED_LINUX-24.07-0.6.1.0-ubuntu24.04-x86_64.tgz \

       && cd MLNX_OFED_LINUX-24.07-0.6.1.0-ubuntu24.04-x86_64 \

       && ./mlnxofedinstall --force --without-fw-update --dpdk --upstream-libs

Please provide help to resolve above.
