dpdk: NUMA warning on non-NUMA system
Added by Victor Julien 4 months ago.

Description
Seeing Notice: dpdk: 0000:01:00.0: unable to determine NIC's NUMA node, degraded performance can be expected. This is strange as this is a single CPU / single NUMA system:
$ lscpu
Architecture: x86_64
...
NUMA:
NUMA node(s): 1
NUMA node0 CPU(s): 0-7
...
- Status changed from Assigned to In Review
- Target version changed from TBD to 8.0.0-beta1
Well, yes, this notice is printed out when the DPDK cannot determine the NUMA node through rte_eth_dev_socket_id function.
It is possible to restrain the output to only systems with multiple NUMA nodes.
But I guess it is good to keep in mind that the more performance logs and conditions we add, the more peculiar it might be to maintain it.
I tried to locally retrieve the NUMA node of one of the interface I have locally installed - but it also returns -1
cat /sys/class/net/wlp0s20f3/device/numa_node
-1
The check is now performed only on multi-numa systems:
