v2020.02: job definition for fastboot on the host via docker

by Stephen Lawrence

Hi, I have some questions about the new adb/fastboot support in LAVA 2020.02 described in the recent Tech Days LAVA presentation [1]. Main initial use cases are Android boot test, before moving on to running Android tests. Android is AOSP 9/10. [1] https://connect.linaro.org/resources/ltd20/ltd20-304/ Taking the boot test use case I was looking at Antonio's Example 1 from his presentation for fastboot deploy, boot and test. I found doc for test in the 2020.02 release note but nothing I could see for deploy or boot. In the LXC approach a typical job definition would have had target and host namespaces, with deploy and boot for the host space to create and boot the LXC container. Looking at Example 1 deploy from the presentation it looks like that is a largely a target fragment as it contains the image binary etc. A host deploy no longer being required as the Docker container is now created outside lava. Similarly the Example 1 boot looks like a target fragment and host boot fragment is not required as LAVA simply needs to run the specified Docker container. Then finally in Example 1 test the scope is the specified docker container so no namespace is required. Is my interpretation of the Example 1 slides correct? I tried some fragments that were causing fundamental errors that caused me to check here. Although as is often the case writing it out helps you get it straighter in your mind. If you have reasons to want to control fastboot for the flashing on the host is that possible? For example if you had the host side process scripted. Does the fastboot Docker OS need to be specified? I'm running 2020.02 on the Worker via lava-docker, with Docker support within the Worker container by sharing the host Docker socket to gain access to the Docker daemon. Regards Steve

job error with new fastboot in docker support

by Stephen Lawrence

Hi, I'm trialling the fastboot support in Docker introduced in LAVA v2020.02 and getting a fundamental job error about the deploy action of the job definition. I've checked against the examples from the recent Linaro Tech Day LAVA presentation but I can't see the source of the error. Could someone familiar with this new support please take a look at the job definition please? I'm thinking it must be something obvious. Error snippet: error_msg: None of the deployment strategies accepted your deployment parameters, reasons given: overlay: "to" parameter is not "overlay" docker: 'docker' not in the device configuration deploy methods download: "to" parameter is not "download" qemu-nfs: Full error: https://lava.genivi.org/scheduler/job/718 Job definition: https://lava.genivi.org/scheduler/job/718/definition One possible cause I can think of is that the LAVA Worker is running 2020.02, whilst the Server is running 2019.03+stretch. My assumption is that the job definition parsing occurs in the dispatcher but maybe that is not correct? The Server will be upgraded to match the Worker of course, but we took a two step approach whilst we first looked into Android support. Thanks for any help, Steve

Lava-Lab "Master" and "Dispatcher" servers configuration details

by koti koti

Hi, initially we have plan to connect 5 boards to my lava-master and lava-dispatchers. Please can some let me know servers configurations for this setup as mentioned below? a. Can you let me know the LAVA master server configuration ? ( Processor/DDR/memory etc... configurations details) b. Can you let me know the Dispatcher server configuration ? (Processor/DDR/memory etc...configuration details) . ( I guess Dispatcher server configuration may be less than Master server configuration) c. PDU (I guess initial we have plan to connect 5 targets) . (If possible please can you share me the Amazon link to orfer) d. Serial port hub . (I guess initial we have plan to connect 5 targets) . (If possible please can you share me the Amazon link to order) Regards, Koti

Audit log for user action?

by Larry Shen

Hi, there, If lava in some place possible to find who cancel a job? Or use lavacli or manual cancel a job? Or for which detail reason, the job was canceled? We are struggling to find why my job canceled sometimes, not sure someone not carefully do it or our external program by chance do it, especially when there are many people used the same master.

Question about send delay for serial.

by Larry Shen

Sometimes for some device, when lava enter "/lava-55904/bin/lava-test-runner /lava-55904/0" It looks it will print: -sh: /lava-55904/bin/lava-test-runnera-55904/0: No such file or directory Looks some character miss. We increases the test_character_delay, looks useful, but I'm interested about the details, so for next which you mentioned in the code: What exactly "slow serial problems(iPXE)" mean, could you explain more about it or any reference materteral I can had a look? Then I could know: yes, it's exactly the same problem I have. >>> Extends pexpect.sendline so that it can support the delay argument which allows a delay between sending each character to get around slow serial problems (iPXE). pexpect sendline does exactly the same thing: calls send for the string then os.linesep.

About health check behavior?

by Larry Shen

Hi, there, Frequently, I found when a job becomes incomplete there will immediately a health check job on that device happen automatically to check the status of the device. But strange, some times I won't see that healthy check job. So, my question is: when I see that healthy check job, is it just by chance? Or it really designed that there will be a healthy check after incomplete job? Thanks. Regards, Larry

"Where're my failed tests, dudes?"

by Paul Sokolovsky

Hello, I hope that the mail subject set up an easy, cheerful background for this discussion ;-). This definitely goes into the "stupid questions" department. My plan was to collect "evidence"/feedback from my colleagues, then at the Connect BUD20, crash into LAVA/QA rooms and ask what I/we are doing wrong. As circumstances changed, but the "testing debt" only builds up, there's little choice but to try figure out these matters over a much narrower pipe. So, before proceeding to the question per se, let me theorize that the reasons why such questions come up at all, are sufficient differences in the intended LAVA usage patterns. In other words, how I'd like to use LAVA on the LITE team side may differ from how LAVA team intends it to be used, or how QA team uses (the biggest user would it be). The issue? How I'd intend to use it is IMHO one the most basic ways to use a test system. So, what's that usage? Well, I'm not much interested in "interactive" use (submit jobs manually from my machine). Our interest is in unattended automated CI, of which the testing system is the second half after the build system. So let me remind how our build system, Jenkins, works. Normally, it just builds binaries and uploads them to a publishing server. It's invisible to me in this phase, and my engineering work goes uninterrupted. But when a build fails, I get an email with details about a failure. And I'll continue to get them while it continues to fail. So, the only option I have is to go see the failure, investigate, and fix it. When I arrive at Jenkins, I can easily see which jobs failed and which not, then within each job, see which builds failed and which succeeded. That's very easy, because failed things are red, and successful things are green. So, we've now arrived at the main question of this email - Why I don't seem to be able to use LAVA in the same way? Why LAVA offers only "Incomplete" and "Complete" job statuses? "Incomplete" is understood - it's an infrastructure failure, such a job is definitely "failed". But "Complete" doesn't give me any useful information whether the job succeeded or failed. Because a "Complete" job may still have any number of tests failed. And that's exactly the "last mile" LAVA misses to go: for any test job, I want to see a cumulative number of test cases which failed, straight at the page like https://lite.validation.linaro.org/scheduler/alljobs . Then, I'd like to filter out jobs which has this number >0. Then I'd like to receive a notification only for "failed" jobs, "failed" defined as "status != Complete OR failed_testcases > 0". So, what am I missing and how to make LAVA work like the above?

2020.02: docker in docker support for fastboot docker deploy

by Stephen Lawrence

Hi, After the recent Linaro Tech Day LAVA presentation I have been looking into the new support in LAVA v2020.02 for deploying fastboot on the host to docker rather than lxc. I am running my lava worker in a docker image derived from the linaro lava docker images and so wanted to ask if the new feature supported docker in docker for the fastboot containerisation? Regards Steve

Submit Job

by Nikolina nici_nigel

Hello, I just started working with hardware, firmware and lava. You have a big documentation, but for me it's sometimes difficult to find something. I wanted to submit a job on just one device like my "bbb-03" and not on every beaglebone-black. Is there a device-tag to choose a device like "device_type: "? My next question is if there is also a worker tag for a job submit? For example I just want to run all "beaglebone-black" on my "worker2". Is there also a list of all job submissions tags with examples? I just found the one for the "actions" part. I'm sorry for disturbing and maybe the stupid question. But thank you for your answer in advance. I wish you a nice day
