Subject: [dpdk-users] Enable MLX5 driver v20.11
Date: Sat, 12 Dec 2020 15:22:09 -0800
Message-ID: <CAAcwi38fEK-JS2OQy6MLVgBp7tP7W5SjPGqs9RbymK+OzUP5qQ@mail.gmail.com> (raw)

I am trying to update my DPDK version from 20.08 to 20.11. I am using the
mlx5 driver, and previously to enable it I had to set
CONFIG_RTE_LIBRTE_MLX5_PMD=y in config/common_base. In 20.11, I see no
option to do so. I was able to build my application (and the sample
applications), but running rte_eth_dev_count_avail() returns 0 and cannot
find any ports.

The steps I did to build DPDK from source were:

$ meson build

$ cd build

$ sudo ninja install

$ sudo ldconfig

Normally I would edit dpdk-20.xx/config/common_base before meson build, but
that file is gone.

What are the steps I need to take to enable mlx5 driver? I also recall that
I don't need to bind the mlx5 driver, is that still the case?
