Thanks Santosh,
I opened a bug to track this [1] missing fix to OVS.

Would you mind pinging there with the upstream git link once accepted?
If more fixes are needed report the set of them there.
Then I could backport from there and surely drop on next OVS Merge.

If you happen to know that the backport to 2.7 has conflicts please if you can help to resolve those as you (and Marcin) are the subject matter experts.

bugs.launchpad.net
On OVS 2.7 (as in artful) there is an open issue which blocks proper execution on arm and thereby to some extend bug 1691659. Now there is a related bugfix in discussion and we have seen a preliminary version that I'll attach.

Good to know that basic test cases are working.

Hi,
more tests done and working on arm as well now.


FYI in general packaged Tests work now:
On install of dpdk-dev you can check your setup and libs via:
  source /usr/share/dpdk/dpdk-sdk-env.sh
  sudo python autotest.py /usr/share/dpdk/test/test "${RTE_TARGET}" "-KNI,power_acpi_cpufreq,power_kvm_vm"
This might be a chance to bring them back as dep8 test - I'll consider that next week when workingon 16.11.2


Since some tests are known to have issues when grouped (depends on setup) you can also run it one by one:
  for test in $(awk '/"Command"/ {gsub("_autotest",""); printf("%s\n",$3)}' autotest_data.py | tr -d '",'); do echo $test; sudo python autotest.py /usr/share/dpdk/test/test "${RTE_TARGET}" "$test"; done


Most tests are good and some are just known issues (KNI, pci for not finding what they need, and power_acpi_cpufreq was alwas weird).
I looked into a few as I was runnign on arm for the first time. There are a few which might be worth to look into: eal_flags, memcpy_perf (timeout)


@Jerin I'd ask you to look into the remaining one's as you suggested.
You can use the ppa  https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/2773 for that.

@Jerin - also if you can afford the time could you test OVS-DPDK from your POV on your platform with the ppa above in place?
