[dpdk-dev] Compiling MLX4 Support into 2.1.0

[dpdk-dev] Compiling MLX4 Support into 2.1.0

[Nathan Speulda]

All,

I am attempting to do some work using a CX3-Pro adapter in a forwarding
environment and am attempting to enable the supported PMD that is included
in the 2.1.0 release of DPDK.  My base distro is RHEL6.5 for stability
reasons.  Does anyone have a more detailed idea of how to get the Mellanox
PMD working correctly?  Does base distro have any impact on this at all?  I
have been unable to find what I need at the Mellanox community support.

Thanks,
Nathan

You need to install Mellanox OFED before attempting to compile the mlx4
PMD, as described in the relevant documentation (doc/guides/nics/mlx4.rst)
also available here:

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

See "Prerequisites" and "Getting Mellanox OFED" sections.

It should work fine with all Linux distributions supported by Mellanox
OFED. In your specific case, RHEL 6.5 is supported by MOFED 3.0-2.0.1.

Thank you for the response,

I followed all of the documentation before I came to the forum on this
one.  OFED is installed and working correctly with all drivers loaded.  I
get to the point of compiling dpdk with support enabled and nothing appears
to come out during the compile (for mlx4 which is included in the
.config).  My interfaces are not being seen by the PMD though I am aware it
works differently than the base supported adapters.

Thanks,
Nathan

Nathan,

What application are you running?
Please send the output of it.
Please send output of ofed_info  -s, ibdev2netdev and ibv_devinfo. Do you see any errors in dmesg?

Regards,
Olga

I understand you do not see anything like the following lines while DPDK is
being compiled?

 == BUILD drivers/net/mlx4
   CC mlx4.o
   AR librte_pmd_mlx4.a
   INSTALL-LIB librte_pmd_mlx4.a

If you don't, something is wrong in your .config, perhaps you haven't
edited the right one? Depending on your target, DPDK may generate another
with default options in an unexpected place and use it instead of your own.

Otherwise, I suggest following Olga's advice, your ports may not be in the
right mode (IB instead of Ethernet), or you're using the wrong kernel
modules in which case mlx4 usually complains during startup.

This is only a guess, please provide compilation, program (testpmd?) startup
logs and the related command line if it still doesn't work.
