Hi,
I'm seeing what looks like benign errors from qdisc on testpmd & our DPDK app on Azure. I'm wondering if anyone knows of a way to 'fix' these?
EAL: Detected 8 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: Detected static linkage of DPDK
EAL: Selected IOVA mode 'VA'
EAL: Probing VFIO support...
EAL: VFIO support initialized

It's not causing any issues that I can see, I'm just wondering if there's a cause for this in the environment that we can fix so we don't have benign errors showing up.
Reproduced by running testpmd with no arguments on Azure:
- OS: Ubuntu 20.04 5.4.0-1048-azure
- DPDK: 20.11.1 (LTS)
- Networking: Azure Accelerated Networking (netvsc)
OS setup is pretty minimal, nothing special other than DPDK is installed.
I don't recall these errors happening while on bare metal - only on Azure.
Thanks!
Regards,
Tyler

In order to support the tap flow emulation you need to hve the ingress qdisc
and the flower qdisc. Some of the Linux distros have packaged those into
kernels extras type packages.
Or just use netvsc PMD and avoid the problem.

I installed *linux-azure-lts-20.04* and *linux-modules-extra-azure-lts-20.04* to no avail - is this the extras package you are referring to? The extra one maps to *linux-modules-extra-5.4.0-1051-azure*.

This is what we use ( --vdev=net_vdev_netvsc0,iface=eth1 ) so I expect the messages are harmless - just wanted to check if there was a way to hide the message.

Strangely nothing seems amiss there either. Starting/stopping dpdk looks OK as well:
[ 38.796800] Mirror/redirect action on
[ 39.200310] device enP24279s2 entered promiscuous mode
[ 39.200331] mlx5_core 5ed7:00:02.0 enP24279s2: S-tagged traffic will be dropped while C-tag vlan stripping is enabled
[ 39.267874] device eth1 entered promiscuous mode
[ 39.268059] device dtap0 entered promiscuous mode
[ 42.006618] device eth1 left promiscuous mode
I attached the dmesg.txt but nothing really stands out as being unusual.
I haven't been able to test with ConnectX-3 yet - unsure if that card would make a difference but our VMs are currently quite attached to X-4 :)
I updated the kernel from 5.4.0-1051-azure to 5.8.0-1036-azure (with the server-backports ppa workaround) and still seem to receive the warnings.
I don't think I included the full testpmd cmd I'm running in an earlier message, but it's pretty straightforward:
sudo /usr/local/bin/dpdk-testpmd -w 5ed7:00:02.0 --vdev=net_vdev_netvsc0,iface=eth1

The next thing to check is version of rdma-core. Long just diagnosed an issue with rdma-core version in Ubuntu 20.4

That's the version I'm using in my last reply -- from ppa:canonical-server/server-backports: 33.1-1ubuntu1~backport20.04-202103240925~ubuntu20.04.1
Noticed now, but with the new kernal and rdma-core librdmacm-dev from backports there are some new mlx5_pci errors. Appears to be working OK otherwise though.

Hi Tyler,
Nvidia helped investigate this.
The message "Failed to allocate Tx DevX UAR (BF)" is diagnostic, not error.
We lowered the log level for this to DEBUG in 21.02. If the further UAR allocation with NC mapping succeeds - there is no known issues about PMD operating.
(if both BF/NC fail - no device probing happens, as we saw).
Hence - just ignore the diagnostic message or use 21.05 or apply the commit " net/mlx5: fix UAR allocation diagnostics messages".
Thanks,
Long

Hi Long,
> The message "Failed to allocate Tx DevX UAR (BF)" is diagnostic, not error.
Thanks - do you have any comment on the qdisc messages or do we just safely ignore these as well?
We are using the rdma-core from ppa:canonical-server/server-backports (33.1-1ubuntu1~backport20.04-202103240925~ubuntu20.04.1).
Regards,
Tyler
