Testcase that looks for BUG: or WARNING: in dmesg

[fbezdeka]

Hi all,

is there really no test case that checks if a kernel warning or bug occurred during the runtime of all or a specific test suite?

I already asked the question in [1] a few month ago but got no answer.
From time to time we can reproduce warnings or even bugs during the runtime of our own test suite.
It took some time to realize that we have real problems as LAVA jobs were marked as "green" or successful.

Yes, of course, I could implement such a check on my own (inline testsuite or even a complete test definition repo) but isn't that something that should be provided here as well?

Did I overlook something?

IMHO you're asking in the wrong place. test-definitions are not LAVA and I believe you're looking for LAVA feature.

Hi @fbezdeka

I wouldn't call it a "suite", but the KernelCI project runs a simple dmesg check script that will run in a generic LAVA environment with some minor changes. It could be a useful starting point for you.

Maybe we could get something similar added to this repo?

You can parse dmesg output after a set of tests.

The project moved to gitlab.com/lava/lava, so the answer is https://gitlab.com/lava/lava/-/issues/576 now.

It should be possible to extend the current LAVA code to support such use-case.
