lava-test-shell timeout : How to run test-suites using lava-test-case/shell/runner where DUT is non-IP or no NFS support

by Nagendra Singamsetti

Hi Team, I had a Query which is particularly to use lava-test-shell or other binaries like lava-test-runner. My board is booted with Linux and It has a POSIX environment but it doesn't support either ssh/nfs due to the low memory footprint available and the ethernet driver not fully functional. To test/run my test-suite drivers How can I use lava-test-runner/ lava-test-shell ? Is it possible to test our suite using lava-test-shell/runner where DUT doesn't have the ethernet/nfs support. I am getting lava-test-shell timeout on the DUT console whereas Lava-worker had all the binaries available by lava-overlay method. Please find the attached test job definition/lava-job log files for your reference. Kindly let me know the solution.

Job does not exiting even after the timeout

by koti

Hi. It looks like I am facing the same problem and the job does not exist even after the timeout. . I guess there might be communication gap between the Dispatcher and server. Dispatcher log screenshot: (/var/log/lava-dispatcher/lava-worker.log) ###################### [image: image.png] any solution to resolve this?

Lava Socket connection error:

Hi Team, I'm running Multi node testing by connecting two devices of the same type. But it results in a socket connection error. I check the lava-coordinator conf file in server and dispatcher, both contain the same configuration.

Enquire if frequent bpf action will cause any performance drop?

by Larry Shen

In fact, I didn't see any performance drop because I'm still trying it in a small and initial phase, just want to eliminate any risk when move to debian11, you know if issue happen in production environment, it maybe really not easy to debug. Back to the question: in lava, if we use debian11 which default cgroupV2 enabled, then when use docker-test-shell, lava will attach a custom BPF Device program to container to replace the default one in docker. Everything looks fine, just I observed if I use "adb devices" in container, then the trace_pipe will be flushed with next: ``` device poll-7289 [001] d... 103054.767620: bpf_trace_printk: Device access: major = 189, minor = 261 device poll-7289 [001] d... 103055.767851: bpf_trace_printk: Device access: major = 189, minor = 261 device poll-7289 [001] d... 103056.768117: bpf_trace_printk: Device access: major = 189, minor = 261 device poll-7289 [001] d... 103057.768354: bpf_trace_printk: Device access: major = 189, minor = 261 device poll-7289 [001] d... 103058.768590: bpf_trace_printk: Device access: major = 189, minor = 261 device poll-7289 [001] d... 103059.768819: bpf_trace_printk: Device access: major = 189, minor = 261 device poll-7289 [001] d... 103060.769053: bpf_trace_printk: Device access: major = 189, minor = 261 ``` Which means that bpf function frequently be called (interval less than 1 second) On the other hand, if I do next then the BPF prog unregistered from linux kernel, but looks every adb devices still works. ``` /sys/fs/cgroup/system.slice/docker-a9354f54a8c6a56932e15b4d577432abf86c897630d5e94da442474e938bf875.scope 78 device multi lava_docker_dev $ bpftool cgroup detach /sys/fs/cgroup/system.slice/docker-a9354f54a8c6a56932e15b4d577432abf86c897630d5e94da442474e938bf875.scope device id 78 ``` So, I just want to confirm have you guys noticed this behavior, and you confirm this behavior is ok? (To be honestly, I'm not sure BPF performance if it's frequently be called, so this is just a enquire) Or, we have better methods handle it in lava? I need your confirm to decide if I need to downgrade to CGroupV1 when I migrate, thanks! Regards, Larry

Configuration Error:

by pawanKumar

Hi, I'm facing an issue after updating the base-uboot file on the server. *Configuration Error: missing or invalid template.* *Jobs requesting this device type will not be able to start until a template is available on the master.* I have restarted the server and dispatcher but no update. All the devices went offline automatically. Any advice to resolve this issue would be appreciated. Thank you

Hello Team After facing " Infrastructure ERror: bootloader interrupt ", I have made changes in the base-uboot.jinja file and restarted the server. But, it says "*Configuration Error: missing or invalid template.* Jobs requesting this device type will not be able to start until a template is available on the master." Please advise how to fix this. Thank you
