Unfortunately logs are insufficient to understand it. I've pushed new tag to TE v1.19.0 which add log message with TE_* environment variables. Most likely something is wrong with variables which are used as conditions when available networks are defined in ts-conf/cs/inc.net_cfg_pci_fns.yml: TE_PCI_INSTANCE_IUT_TST1 TE_PCI_INSTANCE_IUT_TST1a TE_PCI_INSTANCE_TST1a_IUT TE_PCI_INSTANCE_TST1_IUT My guess it that you change naming a bit, but script like ts-rigs-sample/scripts/iut.h1-x710 is not included or not updated. > There is a different error when running on the Intel E810s.

Since this > error seems very non-trivial, I will also attach this log. This one is a bit simpler. Few lines after the first ERROR in log I see the following: WARN  RCF  DPDK  13:06:00.144 ice_program_hw_rx_queue(): currently package doesn't support RXDID (22) ice_rx_queue_start(): fail to program RX queue 0 ice_dev_start(): fail to start Rx queue 0 Device with port_id=0 already stopped It is stdout/stderr from test agent which runs DPDK. Same logs in plain format are available in ta.DPDK file. I'm not an expert here, but I vaguely remember that E810 requires correct firmware and DDP to be loaded. There is some information in dpdk/doc/guides/nics/ice.rst. You can try to add --dev-args=safe-mode-support=1 command-line option described there.

Hi Adam,

Hi Andrew,

The compilation warning issue is now resolved. Again, thank you guys for fixing this for us. I can run the tests on the Mellanox CX5s again, however I'm running into a couple new issues with running the prologues on the Intel cards.

When running testing on the Intel XL710s, I see this error appear in the log:

ERROR  prologue  Environment LIB  14:16:13.650
Too few networks in available configuration (0) in comparison with required (1)

This seems like a trivial configuration error, perhaps this is something I need to set up in ts-rigs. I briefly searched through the examples there and didn't see any mention of how to set up a network.
I will attach this log just in case you need more information.

Unfortunately logs are insufficient to understand it. I've pushed new tag to TE v1.19.0 which add log message with TE_* environment variables.
Most likely something is wrong with variables which are used as conditions when available networks are defined in ts-conf/cs/inc.net_cfg_pci_fns.yml:
TE_PCI_INSTANCE_IUT_TST1
TE_PCI_INSTANCE_IUT_TST1a
TE_PCI_INSTANCE_TST1a_IUT
TE_PCI_INSTANCE_TST1_IUT
My guess it that you change naming a bit, but script like ts-rigs-sample/scripts/iut.h1-x710 is not included or not updated.

There is a different error when running on the Intel E810s. It appears to me like it starts DPDK, does some configuration inside DPDK and on the device, and then fails to bring the device back up. Since this error seems very non-trivial, I will also attach this log.

This one is a bit simpler. Few lines after the first ERROR in log I see the following:
WARN  RCF  DPDK  13:06:00.144
ice_program_hw_rx_queue(): currently package doesn't support RXDID (22)
ice_rx_queue_start(): fail to program RX queue 0
ice_dev_start(): fail to start Rx queue 0
Device with port_id=0 already stopped

It is stdout/stderr from test agent which runs DPDK. Same logs in plain format are available in ta.DPDK file.
I'm not an expert here, but I vaguely remember that E810 requires correct firmware and DDP to be loaded.
There is some information in dpdk/doc/guides/nics/ice.rst.

You can try to add --dev-args=safe-mode-support=1 command-line option described there.

Hope it helps,
Andrew.


Thanks,
Adam

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.

Great. Let me know when that's fixed.

Done. We also fixed a number of warnings in TE.
Also we fixed root test package name to be consistent with the repository name.

Support for old LTS branches was dropped some time ago, but in the future it is definitely possible to keep it for new LTS branches. I think 22.11 is supported, but I'm not sure about older LTS releases.

Good to know.
 
2. You can add command-line option --sanity to run tests marked with TEST_HARNESS_SANITY requirement (see dpdk-ethdev-ts/scripts/run.sh and grep TEST_HARNESS_SANITY dpdk-ethdev-ts to see which tests are marked). Yes, there is a space for terminology improvement here. We'll do it.

Done. Now it is called --checkup.


Also it takes a lot of time because of failures and tests which wait for some timeout.

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.

I'll double-check and let you know how long entire TS runs on Intel X710, E810, Mellanox CX5 and virtio net. Just to ensure that time observed in your case looks the same.

 
The test harness can provide coverage reports based on gcov, but I'm not sure what you mean by a "dial" to control test coverage. Provided reports are rather for human to analyze.

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.

Understood now. Thanks a lot for the idea. We'll discuss it and come back.

 
3. Yes, really many tests on Mellanox CX5 NICs report unexpected testing results. Unfortunately it is time consuming to fill in expectations database since it is necessary to analyze testing results and classify if it is a bug or just acceptable behaviour aspect.

Bublik allows to compare results of two runs. It is useful for human, but still not good for automation.

I have local patch for mlx5 driver which reports Tx ring size maximum. It makes pass rate higher. It is a problem for test harness that mlx5 does not report limits right now.

Pass rate on Intel X710 is about 92% on my test rig. Pass rate on virtio net is 99% right now and could be done 100% easily (just one thing to fix in expectations).

I think logs storage setup is essential for logs analysis. Of course, you can request HTML logs when you run tests (--log-html=html) or generate after run using dpdk-ethdev-ts/scripts/html-log.sh and open index.html in a browser, but logs storage makes it more convenient.

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 use for log storage (see tools/log_server/README.md).

Also all bits for Jenkins setup are available. See dpdk-ethdev-ts/jenkins/README.md and examples of jenkins files in ts-rigs-sample.

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.

Hopefully it is resolved now.

I thought a bit more about your usecase for Jenkins. I'm not 100% sure that existing pipelines are convenient for your usecase.
Fill free to ask questions when you are on it.

Thanks,
Andrew.


Thanks,
Adam

Hi Andrew,

That fix seems to have resolved the issue, thanks for the quick turnaround time on that patch.
Now that we have the RCF timeout issue resolved, there are a few other questions and issues that we have about the tests themselves.

1. The test suite fails to build with a couple warnings.

Below is the stderr log from compilation:

This error wasn't occurring last week, which was the last time I ran the tests.
The TE host and the DUT have GCC v9.4.0 installed, and the tester has GCC v11.4.0 installed, if this information is helpful.

2. On the Mellanox CX5s, there are over 6,000 tests run, which collectively take around 9 hours. Is it possible, and would it make sense, to lower the test coverage and have the test suite run faster?

For some context, we run immediate testing on incoming patches for DPDK main and development branches, as well as periodic test runs on the main, stable, and LTS branches.
For us to consider including this test suite as part of our immediate testing on patches, we would have to reduce the test coverage to the most important tests.
This is primarily to reduce the testing time to, for example, less than 30 minutes. Testing on patches can't take too long because the lab can receive numerous patches each day, which each require individual testing runs.

At what frequency we run these tests, and on what, still needs to be discussed with the DPDK community, but it would be nice to know if the test suite had a "dial" to control the testing coverage.

3. We see a lot of test failures on our Mellanox CX5 NICs. Around 2,300 of ~6,600 tests passed. Is there anything we can do to diagnose these test failures?

Thanks,
Adam

Hi Adam,

I've pushed the fix in main branch and a new tag v1.18.1. It should solve the problem with IPv6 address from DNS.

Brilliant idea. If DNS returns both IPv4 and IPv6 addresses in your case, I guess it is the root cause of the problem.
Of course, it is TE problem since I see really weird code in lib/comm_net_engine/comm_net_engine.c line 135.

I've pushed fix to the branch user/arybchik/fix_ipv4_only in ts-factory/test-environment repository. Please, try.

It is late night fix with minimal testing and no review. I'll pass it through review process tomorrow and
hopefully it will be released in one-two days.

Hi Andrew,

We have yet to notice a distinct pattern with the failures. Sometimes, the RCF will start and connect without issue a few times in a row before failing to connect again. Once the issue begins to occur, neither rebooting all of the hosts (test engine VM, tester, IUT) or deleting all of the build directories (suites, agents, inst) and rebooting the hosts afterward resolves the issue. When it begins working again seems very arbitrary to us.

I do usually try to terminate the test engine with Ctrl+C, but when it hangs while trying to start RCF, that does not work.

Does the test engine prefer to use IPv6 over IPv4 for initiating the RCF connection to the test bed hosts? And if so, is there a way to force it to use IPv4?

Done. It works fine for me without any issues.

Have you noticed any pattern when it works or does not work?
May be it is a problem of not clean state after termination?
Does it work fine the first time after DUTs reboot?
How do you terminate testing? It should be done using Ctrl+C in terminal where you execute run.sh command.
 In this case it should shutdown gracefully and close all test agents and engine applications.

(I'm trying to understand why you've seen many test agent processes. It should not happen.)

Hi Andrew,

Two of our systems (the Test Engine runner and the DUT host) are running Ubuntu 20.04 LTS, however this morning I noticed that the tester system (the one having issues) is running Ubuntu 22.04 LTS.
This could be the source of the problem. I encountered a dependency issue trying to run the Test Engine on 22.04 LTS, so I downgraded the system. Since the tester is also the host having connection issues, I will try downgrading that system to 20.04, and see if that changes anything.

Unlikely, but who knows. We run tests (DUTs) on Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10, Ubuntu 23.04, Debian 11 and Fedora 38 every night.
Right now Debian 11 is used for test engine in nightly regressions.

I'll double-check test engine on Ubuntu 20.04 and Ubuntu 22.04.

I did try passing in the "--vg-rcf" argument to the run.sh script of the test suite after installing valgrind, but there was no additional output that I saw.

Sorry, I should valgrind output should be in valgrind.te_rcf (direction where you run test engine).


I will try pulling in the changes you've pushed up, and will see if that fixes anything.

Thanks,
Adam

In fact I know one problem with Debian 12 and Fedora 38 and we have

this case, so it is unlike the same problem.

I've just published a new tag which fixes known test engine side problems on Debian 12 and Fedora 38.


One more idea is to install valgrind on the test engine host and
run with option --vg-rcf to check if something weird is happening.

What I don't understand right now is why I see just one failed attempt
to connect in your log.txt and then Logger shutdown after 9 minutes.

Our test engine host and the testbed are on the same subnet. The connection does work sometimes.

I was able to replicate the same behavior again, where it hangs while RCF is trying to start.
Running this command, I see this in the output:

tcp        0      0 0.0.0.0:23571 <http://0.0.0.0:23571>           0.0.0.0:*               LISTEN      18599/ta

So it seems like it is listening on the correct port.
Additionally, I was able to connect to the Tester machine from our Test Engine host using telnet. It printed the PID of the process once the connection was opened.

I tried running the "ta" application manually on the command line, and it didn't print anything at all.
Maybe the issue is something on the Test Engine side.

        Hi Adam,

        Yes, TE_RCFUNIX_TIMEOUT is in seconds. I've double-checked
        that it goes to 'copy_timeout' in ts-conf/rcf.conf.
        Description in in doc/sphinx/pages/group_te_engine_rcf.rst
        says that copy_timeout is in seconds and implementation in
        lib/rcfunix/rcfunix.c passes the value to select() tv_sec.
        Theoretically select() could be interrupted by signal, but I
        think it is unlikely here.

        I'm not sure that I understand what do you mean by RCF
        connection timeout. Does it happen on TE startup when RCF
        starts test agents. If so, TE_RCFUNIX_TIMEOUT could help. Or
        does it happen when tests are in progress, e.g. in the middle
        of a test. If so, TE_RCFUNIX_TIMEOUT is unrelated and most
        likely either host with test agent dies or test agent itself

        depending on which agent has problems could shed some light.
        Corresponding files contain stdout/stderr of test agents.

                    Greatings Adam,

                    I'm happy to hear that you're trying to bring
                    it up.

                    As I understand the final goal is to run it on
                    regular basis. So, we need to make it properly
                    from the very beginning.
                    Bring up of all features consists of 4 steps:

                    1. Create site-specific repository (we call it
                    ts-rigs) which contains information about test
                    rigs and other site-specific information like
                    where to send mails, where to store logs etc.
                    It is required for manual execution as well,
                    since test rigs description is essential. I'll
                    return to the topic below.

                    2. Setup logs storage for automated runs.
                    Basically it is a disk space plus apache2 web
                    server with few CGI scripts which help a lot to
                    save disk space.

                    3. Setup Bublik web application which provides
                    web interface to view testing results. Same as
                    https://ts-factory.io/bublik
                    <https://ts-factory.io/bublik>

                    4. Setup Jenkins to run tests on regularly,
                    save logs in log storage (2) and import it to
                    bublik (3).

                    Last few month we spent on our homework to make
                    it simpler to bring up automated execution
                    using Jenkins -
                    https://github.com/ts-factory/te-jenkins
                    <https://github.com/ts-factory/te-jenkins>
                    Corresponding bits in dpdk-ethdev-ts will be
                    available tomorrow.

                    Let's return to the step (1).

                    Unfortunately there is no publicly available
                    example of the ts-rigs repository since
                    sensitive site-specific information is located
                    there. But I'm ready to help you to create it
                    for UNH. I see two options here:

                    (A) I'll ask questions and based on your
                    answers will create the first draft with my
                    comments.

                    (B) I'll make a template/example ts-rigs repo,
                    publish it and you'll create UNH ts-rigs based
                    on it.

                    Of course, I'll help to debug and finally bring
                    it up in any case.

                    (A) is a bit simpler for me and you, but (B) is
                    a bit more generic and will help other
                    potential users to bring it up.
                    We can combine (A)+(B). I.e. start from (A).
                    What do you think?

                    Thanks,
                    Andrew.

                    I have some questions about how to set the

                    I have been able to configure the Test Engine
                    to connect to the hosts in the testbed. The
                    RCF, Configurator, and Tester all begin to
                    run, however the prelude of the test suite
                    fails to run.

                    https://ts-factory.io/doc/dpdk-ethdev-ts/index.html#test-parameters <https://ts-factory.io/doc/dpdk-ethdev-ts/index.html#test-parameters>

                    The documentation mentions that there are
                    several test parameters for the test suite,
                    like for the IUT test link MAC, etc. These
                    seem like they would need to be set somewhere
                    to run many of the tests.

                    I see in the Test Engine documentation, there
                    are instructions on how to create new
                    parameters for test suites in the Tester
                    configuration, but there is nothing in the
                    user guide or in the Tester guide for how to
                    set the arguments for the parameters when

                    not sure if I need to write my own Tester
                    config, or if I should be setting these in
                    some other way.

                    How should these values be set?
