Hi,

 

I’m doing a setup with Mellanox ConnectX-4 (MC= X416A-CCA) NICs.

 

I’m using:

 

OS SLES 15 SP2

DPDK 19.11.4 (the official supported version = for SLES 15 SP2)

MLNX_OFED_LINUX-5.5-1.0.3.2-sles15sp2-x86_64 = (the latest one)

Mellanox adapters firmware 12.28.2006 (corres= ponding to this MLNX_OFED version)

kernel 5.3.18-24.34-default

 

 

This is my SRIOV configuration for DPDK capable PCI = slots:

 

        &nbs= p;   {

        &nbs= p;       "resourceName": "mlnx= _sriov_netdevice",

        &nbs= p;       "resourcePrefix": "me= llanox.com",

        &nbs= p;       "isRdma": true,=

        &nbs= p;       "selectors": {<= /p>

        &nbs= p;           "vendor= s": ["15b3"],

        &nbs= p;           "device= s": ["1014"],

        &nbs= p;           "driver= s": ["mlx5_core"],

        &nbs= p;           "pciAdd= resses": ["0000:d8:00.2", "0000:d8:00.3", "00= 00:d8:00.4", "0000:d8:00.5"],

        &nbs= p;           "isRdma= ": true

        &nbs= p;       }

 

The sriov device plugin starts without problems, the= devices are correctly allocated:

 

{

  "cpu": &= quot;92",

  "ephemeral-st= orage": "419533922385",

  "hugepages-1G= i": "8Gi",

  "hugepages-2M= i": "4Gi",

  "intel.com/in= tel_sriov_dpdk": "0",

  "intel.com/sr= iov_cre": "3",

  "mellanox.= com/mlnx_sriov_netdevice": "4",

  "mellanox.com= /sriov_dp": "0",

  "memory"= : "183870336Ki",

  "pods": = "110"

}

 

The Mellanox NICs are binded to the kernel driver ml= x5_core:
