[dpdk-users] mlx5 fails to probe on 16.11.5

[dpdk-users] mlx5 fails to probe on 16.11.5

[Richard Nutman]

Hi all,

I tried switching from the Mellanox 16.11.4 release to the official DPDK LTS 16.11.5, but having issues getting it to work.

rte_eth_dev_count() returns 0, as mlx5_pci_probe() is never called from rte_eal_pci_probe_one_driver().
Anyone any idea what that would be ?  Works fine in previous Mellanox releases.

Using Centos 7.2, Ofed 4.2-1.

Also in mlx5_ethdev.c -> mlx5_dev_infos_get()
info->flow_type_rss_offloads = ~MLX5_RSS_HF_MASK; 

was added as part of the .5 release, but the mask is undefined and fails to build.

Thanks,

Richard Nutman

Hi Richard, 

mlx5 PMD is not compiled by default in dpdk.org versions due to OFED dependency you need to enable it compilation in configure file.
 
Regarding:
>Also in mlx5_ethdev.c -> mlx5_dev_infos_get()
>info->flow_type_rss_offloads = ~MLX5_RSS_HF_MASK; 

>was added as part of the .5 release, but the mask is undefined and fails to build.

Will check it

Best Regards,
Olga

Hi Olga,

Yes I am building the mlx5 PMD. I'll debug more to see why it doesn't find it. It looks like something todo with the vendor ID's not matching, or something around that area.
I haven't changed my build system or which libraries I'm including between the Mellanox 16.11.4 release and the official DPDK 16.11.5.

I searched for the MLX5_RSS_HF_MASK in the whole 16.11.5 release but couldn't find it.  Commented it out to get it building for the moment, I'm not using RSS anyway.
I presume it's either missed out or in some OFED/IB system headers I do not have ?

Ofed 4.2 installed with just --dpdk option.

Many thanks,
Richard.
