How to fail a test run on kernel warnings that happen after the boot action?

by Florian Bezdeka

Hi all, I'm basically repeating [1] here as there was no reaction for some months now. Maybe I used the wrong communication channel, let's see... We have a testsuite that is able to trigger a RCU WARNING inside the Linux kernel. My expectation was that whenever a kernel warning / oops / call stack dump / ... occurs the LAVA job is marked as "failed". This assumption seems to be wrong. It took some time to realize that we have a real problem as manual inspection of test logs only happens from time to time. After scanning the code my understanding is that the output of the connection (serial connection in my case) is only parsed during kernel boot (until the login action takes over). That is not sufficient for detecting problems that happen during test execution. Is there a way to scan the full log for the same patterns that are used by the boot action? If so, how to configure that? Whenever a kernel problem occurs my test run should be marked as "failed". Any ideas? Did I overlook something? Best regards, Florian [1] https://git.lavasoftware.org/lava/lava/-/issues/576

Test Jobs always going in submitted state for QEMU devices

by Ankit Gupta

Hi All, I am trying to setup LAVA 2023.08 lava-server and lava-dispatcher on a single machine, I successfully installed and was able to add workers and a QEMU device. From logs, it seems the workers are communicating with the lava server, I am trying to execute a simple QEMU sample job and it always going in the submitted state. I verified the device dictionary is correct. As per my understanding if communication is happening between lava-server/worker then a device should be assigned that is configured on the worker, but in my case, no device is assigned to the test job and it always keeps in a submitted state. Can someone let me know if any special settings are required for running a test job on a QEMU device? or share any docs link s to resolve this, any input will be appreciated. My Testjob YAML: https://docs.lavasoftware.org/lava/examples/test-jobs/qemu-amd64-standard-s… Thanks, Ankit

[SSL: CERTIFICATE_VERIFY_FAILED] self signed certificate

by Ankit Gupta

Hi All, I am setting an HTTPS instance of LAVA, I can access the LAVA UI and am able to log in as well. I am using a self-signed SSL certificate. I have added *URL="https://172.16.60.178/ <https://172.16.60.178/>"* in the /etc/lava-dispatcher/lava-worker file and restarted the service. It's giving me the below error. *2023-10-30 07:10:47,383 ERROR -> server error: code 5032023-10-30 07:10:47,383 DEBUG --> HTTPSConnectionPool(host='172.16.60.178', port=443): Max retries exceeded with url: /scheduler/internal/v1/workers/debian/?version=2023.10 (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate (_ssl.c:1123)')))* Do we need to configure some extra settings in case we are using a self-signed certificate? any help will be appreciated. Thanks, Ankit

Bug using SSH as primary connection

by Sebastian Lucas

Hello everyone, There seems to be a bug in LAVA. I was on version 2022.04 and have also tried 2023.03. Both versions have the same bug. The same configurations works in a 2018 build of LAVA on an old machine. I am trying to connect to an always on board via ssh.

How to connect with serial port?

by irreallich＠126.com

I am newer , and I try to make new device. there is no uboot, kerner ... on my system. for boot, we just need run cmd on host "echo "reset 1" > /dev/ttyUSB0" , it is the mcu serial port. then I can get boot log from /dev/ttyUSB1 , it is thesoc serial port. the following is the job device_type: orinshort job_name: for orinshort device timeouts: job: minutes: 20 action: minutes: 15 priority: medium visibility: public actions: - deploy: timeout: minutes: 10 to: flasher images: kernel: url: http://10.19.207.190/static/docs/v2/contents.html#contents-first-steps-using The following is the my device, it is very sample: {# orin test short #} {% extends 'orinshort.jinja2' %} {% set connection_list = ['usb1'] %} {% set connection_tags = {'usb1': ['primary', 'telnet']} %} {% set connection_commands = {'usb1': 'telnet localhost 10009'} %} {% set flasher_reset_commands = ['/tmp/test.sh'] %} {% block body %} actions: deploy: methods: flasher: commands: {{ flasher_reset_commands }} {% endblock body %} I don't know how to set boot with serial port . 1. about cmd echo "reset 1" > /dev/ttyUSB0 0.1 when I input the cmd on the host shell : echo "reset 1" > /dev/ttyUSB0 , soc can be reset 0.2 when I add it to test.sh and run it with the following code in device, soc can be reset too actions: deploy: methods: flasher: commands: {{ flasher_reset_commands }} 0.3 when I use {% set flasher_reset_commands = ['echo "reset 1" > /dev/ttyUSB0) '] %} , it doesn't work. {% set flasher_reset_commands = ['echo \"reset 1\" > /dev/ttyUSB0) '] %} , it is doesn't work. So how to echo cmd to /dev/ttyUSB0 by flasher: -> commands? 2. how to set boot with serial port in device jinja2 file? if I add the fowllowing code , the test can't run boot: connections: serial: usb1 3. I think the normal process is to configure deploy boot and other operations in the job. but I don't know how to do with my case. just run cmd on host "echo "reset 1" > /dev/ttyUSB0" to start system, how to select the method? how to run flasher_reset_commands in job yaml file? 4. If the job can't start job state is Submitted and can't start test, how to debug? where is the log? I am newer and my system is special , it just like docker, there is now uboot kernel, we need special cmd to deploy and boot so it is hard for me, please give me a hand for it.

About timeouts.

by Larry Shen

Hi, guys, I have a question about timeout: 1) For next job, the boot action block's timeout will be 5 minutes, while pdu-reboot timeout will be 10 seconds. timeouts: job: minutes: 10 action: minutes: 5 actions: pdu-reboot: seconds: 10 connection: minutes: 2 actions: - boot: failure_retry: 4 method: bootloader bootloader: u-boot commands: [] prompts: ['=>'] 2. But after we add timeouts to boot actions, the boot action timeout is 2 minutes now, that's OK. But the individual pdu-reboot timeout will be the left time of 2 minutes. actions: - boot: failure_retry: 4 method: bootloader bootloader: u-boot commands: [] prompts: ['=>'] timeout: minutes: 2 My question is: for the second item, if possible we could let pdu-reboot remain the value "10 seconds"? Above is just an example to explain my question. What I really want to achieve is: sometimes, I want to specify the timeout for "uboot wait for interrupt", I want to fail that individual sub-action quickly, then we are possible retry this action quickly without wait for the whole boot action timeout. Any idea? Thanks. Regards, Larry

How does the device run spcial cmd to build, burn and boot?

by irreallich＠126.com

Hi, There are mcu and soc on my board, two serial port for them( ttyusb0:mcu, ttyusb1:soc), the hostpc ( it is used for lava worker) connected to the two serial ports, and reboot soc cmd is echo "soc boot" > /dev/ttyUSB0 . then we can see boot log at ttyUSB1. We want to use lava to test soc system, it is arm64 with linux , without uboot . and we hope to add build action in the device. So the deploy and boot steps should be: 1. run build.sh on hostpc (it should be lava worker) and check the result (failed and pass) 2. run echo "soc burn" > /dev/ttyUSB0 on hostpc to change the soc to burn mode, and check the result (failed and pass) 3. run burn.sh on hostpc to burn to soc , and check the result (failed and pass) 4. run echo "soc boot" > /dev/ttyUSB0 to reboot soc , and check the result (failed and pass) 5. connect to /dev/ttyUSB1 to get soc boot log, and check the result (failed and pass) 6. ssh to the linux of soc. What I want to know is: 1. Is the above design feasible on lava? 2. What do I need to do for this? Are there any device type templets that I can refer to? The following is my lava system, I can run the test job with qemu device now. ~/work/src/lava $ dpkg -l |grep lava ii lava 2022.11.1+10+buster all Linaro Automated Validation Architecture metapackage ii lava-common 2022.11.1+10+buster all Linaro Automated Validation Architecture common ii lava-coordinator 2022.11.1+10+buster all LAVA coordinator daemon ii lava-dev 2022.11.1+10+buster all Linaro Automated Validation Architecture developer support ii lava-dispatcher 2022.11.1+10+buster all Linaro Automated Validation Architecture dispatcher ii lava-dispatcher-host 2022.11.1+10+buster all LAVA dispatcher host tools ii lava-server 2022.11.1+10+buster all Linaro Automated Validation Architecture server ii lava-server-doc 2022.11.1+10+buster all Linaro Automated Validation Architecture documentation ii lava-tool 0.25-2 all deprecated command line utility for LAVA ii lavacli 0.9.7+buster all LAVA XML-RPC command line interface ~/work/src/lava $
