Thank you for testing release candidates and releases [1]. Is your test
setup documented somewhere?

Not really, except its source is available at github:

Thank you.

If not happening already, could the Linux messages (at least up to log level
warning) also be monitored? For example, in Linux 5.14, a new warning snuck
in by cefc7ca462 (ACPI: PRM: implement OperationRegion handler for the
PlatformRtMechanism subtype) [2], which could have been caught early on, and
fixed before the release.

The test summaries would then also notify about possible behavior change.

Logs are available and can be examined at kerneltests.org/builders.

Sorry for being blind. Under *qemu-tests*, looking at build #1831 [1], clicking on *stdio* [2] under *Steps and Logfiles*, I do not see any Linux logs.

Reports are generated manually, so it would be way too much effort to add
build warnings to those. Besides, logs are way too noisy to be useful in a
summary e-mail.

Just to avoid misunderstandings, it’s about the Linux run-time logs.

Also, Geert's build reports already provide build warnings and errors.
The same applies to reports sent by 0-day. Indeed, I do see at least
one 0-day report against commit cefc7ca46235.

How can I find that report?

What would be the point of adding yet another report of build
warnings on top of that ?
If the functionality already exists, great. But to be clear, it’s about the runtime logs.


Kind regards,

Paul
