I think the patch is the following: https://patches.dpdk.org/project/dpdk/patch/20200603150602.4686-7-ophirmu@m= ellanox.com/ and the code part that solves the error is: + if (mlx5_class_get(pci_dev->device.devargs) !=3D MLX5_CLASS_NET) { + DRV_LOG(DEBUG, "Skip probing - should be probed by other m= lx5" + " driver."); + return 1; + } Could you please confirm?

I have installed it but the problem persists. It's probably solved in 19.11= .11. There is a RPM package in SLES 15 SP3 for DPDK 20.11.3, which is LTS also, = not sure if it could be a problem to install it in SLES 15 SP2. I will try = it anyway.

We'll need to check, but how do you want to proceed?=

You either need 19.11 LTS or 20.11 LTS to work prope= rly.

Hi Asaf,

 

Yes, it seems that DPDK version 20.08 code is built= -in with the VNF I’m deploying, so it is always using this version, w= hich apparently doesn’t have the patch that overrides this error.

 

I think the patch is the following:

 

and the code part that solves the error is:

+ = ;      if (mlx5_class_get(pci_dev->device.devar= gs) !=3D MLX5_CLASS_NET) {

+ = ;            &n= bsp;  DRV_LOG(DEBUG, "Skip probing - should be probed by other ml= x5"

+ = ;            &n= bsp;          " driver.&q= uot;);

+ = ;            &n= bsp;  return 1;

+ = ;      }

Could you please confirm?

 

Thanks,

I see two differences below.

First, in testpmd the version is 19.11.11, and in y= our application, it’s 20.08. See this print:

{"version":&qu= ot;0.2.0","timestamp":"2022-01-20T19:19:16.610+00:00&qu= ot;,"severity":"info","service_id":"eric= -pc-up-data-plane","metadata":{"proc_id":"6&q= uot;},"message":"[pio] USER1: DPDK version: DPDK 20.08.0&quo= t;}

 

Second, in your application, I see the VFIO driver = is not started properly:

20T19:19:16.637+00:00","severity":&q= uot;info","service_id":"eric-pc-up-data-plane",&qu= ot;metadata":{"proc_id":"6"},"message":&= quot;[pio] EAL:   cannot open VFIO container, error 2 (No such fi= le or directory)"}

Although inbox drivers come with a pre installed DP= DK, you can manually download, compile, install, and work with whatever ver= sion you wish.

 

Let us know the results, and we'll continue from th= ere.

Hi Asaf,

Thanks for the prompt answer.

I have checked that the latest 19.11 LTS is 19.11.11, but in OpenSUSE repos= itories the corresponding RPM package for SLES 15 SP2 is not available, the= latest one is DPDK 19.11.10.

I have installed it but the problem persists. It's probably solved in 19.11= .11.

There is a RPM package in SLES 15 SP3 for DPDK 20.11.3, which is LTS also, = not sure if it could be a problem to install it in SLES 15 SP2. I will try = it anyway.

Also I will try to find other way to load the 19.11.11 in SLES 15 SP2 apart= from using RPM or zipper, any suggestion is appreciated.

Thanks,

Roc=EDo
