No, specific reason. When I enabled MLX5 NICs and compilation (as mentioned in trail mail) of VPP (stable/2009 branch) code was successful. But I got the below error while running VPP: /usr/bin/vpp: symbol lookup error: /usr/lib/librte_pmd_mlx5_glue.so.20.02.0: undefined symbol: mlx5_malloc
After applying the below patch, above issue resolved and able to see the interfaces. https://inbox.dpdk.org/stable/[email protected]/T/ Thanks for your help, Varun -----Original Message----- From: Benoit Ganne (bganne) <[email protected]> Sent: Tuesday, December 21, 2021 4:04 PM To: 汪翰林 <[email protected]>; Varun Rapelly <[email protected]> Cc: [email protected]; [email protected]; [email protected] Subject: [EXT] RE: [vpp-dev] MLX5 NIC interface is not visible External Email ---------------------------------------------------------------------- Any reason for not using the rdma driver?
