How to run QEMU in DUT and gdb the QEMU in another console

by 叶轩杨

Hello! I want to run QEMU in DUT and gdb the QEMU in another console to simulate something like a bit flip in memory. What should I do? I just need the new console to run some gdb scripts, like `rust-gdb vmlinux -ex 'target remote /tmp/gdb_socket' -ex 'set *0x40001000 ^= (1<<5)' -ex `c` `, so the new console can not be interactive, live to run some command is enough. Thanks!

Run pytest suite on DUT using LAVA

by Singamsetty Nagendra

Hello everyone, I would like to integrate & run a bare metal custom tests suite(pytest) on lava. Currently I am executing manually from Host Machine(where pytest is configured and pytest suite will execute) and these commands are sent to DUT and results are collected on Host Machine. I am familiar with lava-interactive method but it looks like it will not suit this requirement(Run pytest on Host and collect logs from DUT). Does lava suits for this requirement? if someone could give me advice on this that would be great support. Regards Nagendra S

How to loop test reboot

by irreallich＠126.com

Hi, I hope to be able to test whether the system can boot normally after multiple restarts (10,000 times) Because every boot requires the auto_login of the boot action, it seems that a loop needs to be implemented in yaml, and this loop needs to include the boot action. Are there any relevant examples that you can refer to? There are roughly two types of test logic 1: while (a<10000) { -boot auto_login - test basic io test software reboot in target board a=a+1 } 2: while (a<10000) { -boot auto_login - test basic io test a=a+1 hardware reboot in worker } Thanks

transfer_overlay wget wont work on DUT

by Michael Peddie

Hi, I am trying to use transfer_overlay as the fs on my DUT is read-only, but the /data/ and /tmp/ directories are writeable to some extent. I have a working method to use wget, and it works when I use it manually to download the overlay tarball over http, both on my DUT and on the worker device. However, the LAVA test itself always returns the error 'Network Unreachable' What are the possible reasons for this? Best regards, Michael

Lava Test/Dev Environment Setup Best Practices

by Swapnil Tilaye

Hi Team Currently for the developing and running of the lava tests, we always run on the Lava master machine through lavacli. But we would like to skip the part of the running the tests from the lava master machine while developing, testing and triaging the tests written in the lava. We only want to run tests which are tested correctly to be run on through ci/cd on the lava master and for development, triaging we want to only use the lava-worker and board. We only want to use the lava master only through CI/CD. [cid:86e0132a-a975-4d04-9f31-9a89237339d8] Is there any way to run tests directly from the lava worker instead of going through lava master. I tried "lava-test-shell" and "lava-dispatcher" but it didnt work for me. Can I use the lava api for developing and triaging the test scripts? Can you please recommend the best practice or setup for developing, testing and triaging the tests written in the lava? so that anyone can run, develop or modify tests quickly and make sure its successful and then only it can run through the lava master machine. Regards, Swapnil Tilaye

Possible regression: LAVA breaks initrds/ramsisks with attached microcode

by Florian Bezdeka

Hi all, over the last days I was trying to bring up a setup where we simply try to boot up a kernel and initrd combination that is provided by Debian "as is". Sounds trivial at first but I ran into a problem with the initrd: The initrd contains some microcode, shipped as prepended uncompressed archive. The microcode is added because the intel-microcode package was installed during image generation. When such an initrd enters the LAVA machinery, where the initrd is first unpacked and later re-packed the file gets corrupted in a way that the kernel is unable to unpack/use it. The end result was that NFS boot did not work as the mounting of the rootfs did not take place. Interestingly there is no error message, not within the unpack/repack step in LAVA and the kernel does not complain later during the boot sequence either. To disable the LAVA unpack/repack sequence I had to modify my deploy action. Setting install_overlay and install_modules [2] to false seems to qualify as workaround: - deploy: timeout: minutes: 15 to: tftp kernel: url: <kernel-url> ramdisk: url: <initrd-url> install_overlay: false install_modules: false Looking at the initramfs-tools implementation [1] I think that something similar is missing in LAVA. Does that make sense? Ideas / comments?

Compare builds (from SQUAD (backend is LAVA)) gives the message "No tests to display"

by koti

Hi , I am comparing the LAVA tests from the below SQUAD lkft Android project URL . But I am getting the message "No Tests to display". https://qa-reports.linaro.org/_/comparebuilds/?project=android-lkft-benchma… Can someone let me know the solution to compare the tests in different builds from the project "android-lkft-benchmarks <https://qa-reports.linaro.org/android-lkft-benchmarks/>" ? Note: 1. But, we are able to get compare test list for LKFT project builds. But not for Android build as I mentioned above email. Do not know the reason. https://qa-reports.linaro.org/_/comparebuilds/?project=lkft/linux-stable-rc… Regards, Koti
