Hi Maxim,

Pardon my ignorance but where are these tests being added to?

I just read very quickly about openem[1] and this might be something we're interested in using as a test for our scheduler work. Can you describe a bit more where openem originates and how you use it inside LNG?

Regards, Amit

Hi Amit,

1. this test proposed for git://git.linaro.org/qa/test-definitions.git

2. In general commit has bash script which downloads openem, compiles it as suggested in README and run some basic changes. Output of test can be found here: http://validation.linaro.org/scheduler/job/80939/log_file

Next work will be to remove dpdk dependence and do some arm optimizations.

Thank you, Maxim.
