[v2] app/testpmd: optimize membuf pool allocation
Checks
Commit Message
By default, testpmd will create membuf pool for all NUMA nodes and
ignore EAL configuration.
Count the number of available NUMA according to EAL core mask or core
list configuration. Optimized by only creating membuf pool for those
nodes.
Fixes: c9cafcc ("app/testpmd: fix mempool creation by socket id")

This is causing testpmd fail for the case all cores from socket 1 and added a
virtual device which will try to allocate memory from socket 0.
$ testpmd -l<cores from socket 1> --vdev net_pcap0,iface=lo -- -i
...
Failed to setup RX queue:No mempool allocation on the socket 0
EAL: Error - exiting with code: 1
Cause: Start ports failed

It's an open question as to why pcap driver tries to allocate on socket
0 when everything is on socket 1, but perhaps a better improvement would
be to take into account not only socket ID's of lcores, but ethdev
devices as well?

Hi Anatoly,
Agree.
Since NUMA-aware is enabled default in testpmd, so it should be configurable for vdev port NUMA setting.
testpmd -l <cores from socket 1> --vdev net_pcap0,iface=lo --socket-mem=64 -- --numa --port-numa-config="(0,1)" --ring-numa-config="(0,1,1),(0,2,1)" -i
...
Configuring Port 0 (socket 0)
Failed to setup RX queue:No mempool allocation on the socket 0
EAL: Error - exiting with code: 1
Cause: Start ports failed
This should be a defect.
Thanks
Phil Yang

Hi Anatoly/Yigit,
I've prepared a patch to fix this issue.
I will send out the patch once the internal review is done.
Thanks,
