Hi Bill,

Glad to hear that everything is working for you ☺
Let me know if you have any  question or you have figured out what was wrong with your compilation

Best Regards,
Olga

Hi Olga,

Sorry for slow response. Initially, raw_ethernet_bw and raw_ethernet_lat were not working.

* we clean installed some boxes, rather than upgrading from previous ofed etc and now the raw_ethernet_bw and raw_ethernet_lat work. (This is on ubuntu14.04 with most recent mellanox ofed release).

* dpdk-2.1 still did not work. We clean installed the build box, to clear any possibility of mismatches due to upgrade process. Still not working.

* at the suggestion of one of our developers, we switched from statically linking dpdk and libibverbs to static dpdk and dynamic libibverbs. Now the dpdk test programs work.

* at this point, we've switched back to our own kernel build (with patches), our own dpdk programs, and everything appears to be correct.

Apologies for the firedrill -- we do not yet know the exact root cause, but it appears to be related to having done an upgrade of mellanox ofed on the ubuntu14.04 boxes AND building with static linking of libibverbs (though we double checked that the correct .a file was being linked). I will let you know if we have a more satisfactory answer -- we're also more highly prioritizing hermetic builds at this point.

thanks for your help and hints!

Hi Bill,

Sorry it took me a while to reply ….
We did more tests and didn’t reproduce the issue.
I also checked the code and seems that there are only 2  conditions when RD creation fails,

1.       The arguments we are passing to the RD creation function are wrong – this is not reasonable, because this is PMD code and here the behavior is not deterministic , works in most cases and doesn’t work on your setup …

2.       calloc function is failing – also not reasonable

There is a verb  application that uses accelerated verbs and res domains, raw_ethernet_bw
Example:
raw_ethernet_bw -d mlx4_0  -i 1  --client -E 00:00:00:00:01:02 --use_res_domain --verb_type=accl

Another suggestion, can you please compile PMD with debug enabled, it may give more details …

Best Regards,
Olga

Hi Olga

Thanks for the pointer towards the use of "accelerated verbs".

Yes, SRIOV is enabled, dpdk on the hypervisor on the probed VFs. That said, it also fails on the underlying PF as far as I see (e.g. below the log shows (VF: false) for device mlx4_0 and the code fails in RD creation on this as well as on one of the VFs). I don't see any messages generated in dmesg that seem to indicate errors at any point, but extract included below.

But here's perhaps the crux! Switching off sriov and running with the new combination of dpdk and ofed against just a single PF also fails in exactly the same way (RD creation failure).

The old code continues to work. I will audit our code to make sure we're not missing something when using dpdk-2.1. In the meantime, do you have a minimal test that involves RD creation?

thanks
bill

Hi Bill,

Starting from DPDK 2.1 ConnectX-3 PMD is based on “accelerated verbs”,  ibv_exp_create_res_domain is coming from this new API.
Just to make sure I understand what you are doing:  you have enabled SRIOV and you are running DPDK on hypervisor on the probed VFs that you have created, right?
We did test this combination (dpdk2.1 and ofed3.1-3)on hypervisor on the PF and also on VM on VF, but in fact, I didn’t try to run DPDK on the VFs on hypervisor, I will check this.
Meanwhile, can you please send the output of the application on the start up.  Do you see any errors in dmesg?

Best Regards,
Olga

If it's all all helpful, linking our code against dpdk-2.0 and (statically) against the appropriate custom-built libibverbs that we used with it, works on those machines. There is of course no call to ibv_exp_create_res_domain() in that version of the library. But it at least confirms basic operation of the upgraded OFED and firmware on those boxes.

Is there anything else we can check or confirm for you?

thanks
bill

There shouldn’t be any problem with what you are doing.
We are checking this now.

Subject: [dpdk-dev] Mellanox PMD failure w/DPDK-2.1.0 and MLNX_OFED-3.1-1.0.3

Hello

I wonder if anyone can suggest why previously working dpdk code may fail in the Mellanox pmd code in dpdk-2.1.0, seemingly due to failure to create a "resource domain" via ibv_exp_create_res_domain(). I must admit I haven't seen that verb before, and it appears to be returning null with no error message.

The DPDK log gives these hints:

PMD: librte_pmd_mlx4: 0xa4fc20: TX queues number update: 0 -> 1
PMD: librte_pmd_mlx4: 0xa4fc20: RX queues number update: 0 -> 1
PMD: librte_pmd_mlx4: 0xa4fc20: RD creation failure: Cannot allocate memory

I'm using dpdk-2.10.0 and  MLNX_OFED_LINUX-3.1-1.0.3 on ubuntu14.04 with a
connectx-3 card.

thanks
bill
