Hi Asaf,

We have replaced the Mellanox NICs by Intel NICs trying to avoid this problem, but it's not working also, this time with the following error:

Any idea on what could be causing the error this time?

We'll need to check, but how do you want to proceed?
You either need 19.11 LTS or 20.11 LTS to work properly.

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, which apparently doesn't have the patch that overrides this error.



I think the patch is the following:

https://patches.dpdk.org/project/dpdk/patch/20200603150602.4686-7-ophirmu@mellanox.com/<https://protect2.fireeye.com/v1/url?k=31323334-501d5122-313273af-454445555731-cfe08b886ec13ca0&q=1&e=a23c8b9f-0b11-4341-81c9-8931cfbdf633&u=https%3A%2F%2Fpatches.dpdk.org%2Fproject%2Fdpdk%2Fpatch%2F20200603150602.4686-7-ophirmu%40mellanox.com%2F>



and the code part that solves the error is:

+       if (mlx5_class_get(pci_dev->device.devargs) != MLX5_CLASS_NET) {

+                DRV_LOG(DEBUG, "Skip probing - should be probed by other mlx5"

+                        " driver.");

+                return 1;

+       }

Could you please confirm?



Thanks,



Rocío

I see two differences below.

First, in testpmd the version is 19.11.11, and in your application, it's 20.08. See this print:

{"version":"0.2.0","timestamp":"2022-01-20T19:19:16.610+00:00","severity":"info","service_id":"eric-pc-up-data-plane","metadata":{"proc_id":"6"},"message":"[pio] USER1: DPDK version: DPDK 20.08.0"}



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

20T19:19:16.637+00:00","severity":"info","service_id":"eric-pc-up-data-plane","metadata":{"proc_id":"6"},"message":"[pio] EAL:   cannot open VFIO container, error 2 (No such file or directory)"}

Any idea on what could be the problem?



Thanks,

Although inbox drivers come with a pre installed DPDK, you can manually download, compile, install, and work with whatever version you wish.



Let us know the results, and we'll continue from there.

Asaf Penso

Hi Asaf,

Thanks for the prompt answer.

I have checked that the latest 19.11 LTS is 19.11.11, but in OpenSUSE repositories 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,

Rocío

Hello Rocio,
IIRC, there was a fix in a recent stable version.
Would you please try taking latest 19.11 LTS and tell whether you still see the issue?

Regards,
Asaf Penso
