* [dpdk-users] Compile DPDK 17.11 with Mellanox NIC support @ 2018-01-05 7:38 george.dit 2018-01-05 7:46 ` Nelio Laranjeiro 0 siblings, 1 reply; 10+ messages in thread From: george.dit @ 2018-01-05 7:38 UTC (permalink / raw) To: users Hi, I noticed that DPDK 17.11 brought some changes regarding the Mellanox drivers, hence my compilation script does not work for this version of DPDK. Specifically, the release notes of this version state: "Enabled the PMD to run on top of upstream Linux kernel and rdma-core libs, removing the dependency on specific Mellanox OFED libraries." Previously, I was setting CONFIG_RTE_LIBRTE_MLX5_PMD but now, with this option set I get build errors in drivers/net/mlx5/mlx5.c. Could you please provide some guidance on how DPDK is expected to work without OFED? Is there any other configuration required?

You should find anything useful in the NIC documentation [1], you have two possibilities, keep using the distribution and install MLNX_OFED 4.2, or update the Linux Kernel and use RDMA-Core, both are explained in he section "21.5.1.
