Trouble bringing up dpdk testpmd with Mellanox ports

[Sindhura Bandi]

Hi,


I'm trying to bring up dpdk-testpmd application using Mellanox connectX-5 ports. With a custom built dpdk, testpmd is not able to detect the ports.


OS & Kernel:

Linux debian-10 4.19.0-17-amd64 #1 SMP Debian 4.19.194-2 (2021-06-21) x86_64 GNU/Linux

The steps followed:

  *   Installed MLNX_OFED_LINUX-4.9-4.0.8.0-debian10.0-x86_64 (./mlnxofedinstall --skip-distro-check --upstream-libs --dpdk)
  *   Downloaded dpdk-18.11 source, and built it after making following changes in config

           CONFIG_RTE_LIBRTE_MLX5_PMD=y
           CONFIG_RTE_TEST_PMD_RECORD_CORE_CYCLES=y
           CONFIG_RTE_BUILD_SHARED_LIB=y

  *   When I run testpmd, it is not recognizing any Mellanox ports

I'm not sure where I'm going wrong. Any hints will be much appreciated.

Thanks,
