Override method param per device?

by Kumar Gala

Guys, Is it possible for one board/device instance to override a methods param? Specifically if I want to set ‘resets_after_flash’ to ’true’ for one disco-l475-iot1 board instance. Here’s the device type definition: https://git.lavasoftware.org/lava/lava/blob/master/lava_scheduler_app/tests… thanks - k

record measurement

by Frank, Matthias

Hi, I want to measure some output values of test cases. I have a shell script which run stress-ng, parse it's output and exports some measurement variables. How can I record theses variables? I tried to use lava-test-case -shell myscript.sh -result pass -measurement $VAR1 -unit unit but no values are recorded. Maybe this is the wrong approach, but how can I do this in the correct way?

Running MultiNode job on specific devices

by Frank, Matthias

Hello lava users, how can I run a multinode job on specific devices instead of (a possible set) of device_types? I plan to run CAN or RS485 communication tests which requires a wired connection between duts. Is is possible to submit a job to theses special duts or should is have device_types with only on device instance? Greetings, Matthias

jobs using notify with tokens, resubmit as different user

by Kevin Hilman

How can you have more than one LAVA user have the same token secret (e.g. for a notify callback.)? Example use case: - LAVA job with notify callbacks using token names - submited as user "bob", token names of "bob" map to actual token secrets - job fails - user "lab-admin" fixes some lab issues, re-submits job - job passes, but callbacks fail because tokens are associated with user "bob" Since the re-submitted job runs as user "lab-admin", the same token names and corresponding secrets don't exist. Naively, user "lab-admin" tries to copy the token secrets from user "bob" keeping the same token names, but this fails saying that "secret already exists". Why can't different users have the same secrets? I haven't looked at the code, but this limitation kind of suggests that the secret itself is the key in the db, which would prevent multiple secrets of the same. Kevin
