Re: Setting up DPDK PMD Test Suite

Hi Andrew,

I have one additional question as well: Does the test engine support
running tests on two ARMv8 test agents?

1. We'll sort out warnings this week. Thanks for heads up.

Good to know.

That makes sense to me. We'll use the time to complete tests on virtio or
the Intel devices as a reference for how long the tests really take to
complete.
We will explore the possibility of periodically running the sanity tests
for patches.

The general idea is to have some kind of parameter on the test suite, which
could be an integer ranging from zero to ten, that controls how many tests
are run based on how important the test is.

Similar to how some command line interfaces provide a verbosity level
parameter (some number of "-v" arguments) to control the importance of the
information in the log.
The verbosity level zero only prints very important log messages, while ten
prints everything.

In much the same manner as above, this "dial" parameter controls what tests
are run and with what parameters based on how important those tests and
test parameter combinations are.
Coverage Level zero tells the suite to run a very basic set of important
tests, with minimal parameterization. This mode would take only ~5-10
minutes to run.
In contrast, Coverage Level ten includes all the edge cases, every
combination of test parameters, everything the test suite can do, which
takes the normal several hours to run.
The values 1 - 9 are between those two extremes, allowing the user to get a
gradient of test coverage in the results and to limit the running time.

Then we could, for example, run the "run.sh" with a level of 2 or 3 for
incoming patches that need quick results, and with a level of 10 for the
less often run periodic tests performed on main or LTS branches.

We are interested in setting up Bublik, potentially as an externally-facing
component, once we have our process of running the test suite stabilized.
Once we are able to run the test suite again, I'll see what the pass rate
is on our other hardware.
Good to know that it isn't an issue with our dev testbed causing the high
fail rate.

For Intel hardware, we have an XL710 and an Intel E810-C in our development
testbed. Although they are slightly different devices, ideally the pass
rate will be identical or similar. I have yet to set up a VM pair for
virtio, but we will soon.

Latest version of test-environment has examples of our CGI scripts which we

Jenkins integration, setting up production rig configurations, and
permanent log storage will be our next steps once I am able to run the
tests again.
Unless there is an easy way to have meson not pass "-Werror" into GCC. Then
I would be able to run the test suite.

Thanks,
Adam
