tl;dr automatic bisection reports are enabled for mainline and stable
In case you're not already familiar with it, the kernelci.org project is a community effort to build and test upstream kernel trees on a variety of hardware platforms. Reports are mostly sent to the kernel-build-reports mailing list[1] and all the results can be seen on https://kernelci.org.
When a boot test regression is detected on mainline or stable branches, a bisection is automatically run. Starting from today, an email report will be automatically sent to a list of recipients based on the commit the bisection has found (author, trailers, maintainers and lists associated with the code changed by the commit). Until now, the results were manually curated and only reported more widely when they seemed valid. Some automated checks are now used, they have been showing good results for a while with no false positives.
There shouldn't be many bisection reports yet, typically one or two every month. As we'll start bisecting other trees such as linux-next and other test results than just plain boots, the volume may start increasing gradually over the coming months.
Please let us know if you would like the report format to be changed when you get one, or if you have any suggestions at all.
Hope this helps!
