Re: Compilation of MLX5 driver

Hi Shahaf,

1. Can you please explain what is the meaning of upstream-libs?
2. We use Ubuntu 12.04. so if we would like to stay with it, and use MLNX_OFED-4.0, which latest DPDK version should be used?

Thanks,
Asaf

Hi Asaf,

Subject: RE: [dpdk-dev] Compilation of MLX5 driver

Additional details:

Ubuntu: 12.04.3
Linux: 3.2.0-53-virtual
GCC: 4.7.2 (Ubuntu/Linaro 4.7.2-11precise2)

I tried to build DPDK 18.05 after installing the Mellanox OFED driver

DPDK version 18.05 supports only upstream-libs (rdma-core).  

(MLNX_OFED_LINUX-4.0-2.0.0.1-ubuntu12.04-x86_64), but it failed with 
the mentioned error.
So I removed the OFED driver and installed the EN driver (mlnx-en-4.0- 
2.0.0.1-ubuntu12.04-x86_64), but it also failed with the same error.
Both drivers were compiled with "--dpdk" argument ("--upstream-libs" 
is not supported).

Yes MLNX_OFED-4.0 is too old for upstream libs. You should use MLNX_OFED-4.2 and above. 
Or alternatively use an older DPDK version (not recommended).

Can you please advise?

Yes,I installed it using --dpdk --upstream-libs. What is the way 
forward now?

In v17.05 MLX5 PMD is still relying on libibverbs and libmlx5, the way 
Those options you used are necessary to select in their package the 
installation of
libverbs,libmlx5 or rdma-core.
Doing this you have selected rdma-core which is not supported in 
v17.05 DPDK version.

You need to install Mellanox OFED without those two options to select 
libibverbs, libmlx5 to make it work.

Hi,
It has following files:

arch.h  ib.h  kern-abi.h  mlx4dv.h  mlx5dv.h  opcode.h  sa.h 
sa-kern-abi.h  verbs.h

I tried with both MLNX_OFED_LINUX-4.2-1.0.0.0 and
MLNX_OFED_LINUX-4.2-1.2.0.0-ubuntu14.04-x86_64

Did you installed Mellanox OFED with the --dpdk --upstream-libs

arguments for the installation script?

If it is the case, you should not add them for this version, those 
options are

for DPDK v17.11 and higher.

I have installed MLNX_OFED _LINUX-4.2-1.2.0 on my Ubuntu 14.04

Which version of DPDK are you using (it is important to help)?
