[dpdk-dev] Multi-process model and mlx4 pmd

[Olga Shern]

Hi Bill, 

Some clarification:

On Mellanox web we have released updated PMD that supports DPDK 1.7/1.8.

the primary and secondary multi-process model limitation is missing  in http://dpdk.org/doc/guides/nics/mlx4.html
just because we  forgot to mention it.

In general,  there is currently no mlx4 PMD that supports this feature, this is current limitation and we plan to add this feature in the future

Best Regards,
Olga

I see from the Mellanox PMD release notes:

http://www.mellanox.com/related-docs/prod_software/Mellanox_ConnectX3_ConnectX3Pro_DPDK_PMD_Release_Notes_v1.7-8_2.8.4.pdf

that the primary and secondary multi-process model is not supported. Though it's not noted as a limitation in the DPDK guide here:

http://dpdk.org/doc/guides/nics/mlx4.html

Can anyone shed light on what the source of the limitation is? Is this something that can be worked around, or fixed in the driver, or something fundamental?

thanks
