KernelCI is hosting a bi-weekly call on Thursday to discuss improvements to existing upstream tests, the development of new tests to increase kernel testing coverage, and the enablement of these tests in KernelCI.
This is interesting. Is it possible for me to join this bi-weekly call? If so, can you send me info on how to join?
We have sent an invitation to the meeting, let us know if you didn't receive it and we'll resend it. Please note that the meeting is currently scheduled for 13:00 UTC, which unfortunately is not very PDT-friendly.
In recent months, we at Collabora have focused on various kernel areas, assessing the tests already available upstream and contributing patches to make them easily runnable in CIs.

*Boot time test*
- Investigating possibility of adding new test upstream to measure the kernel boot time and detect regressions
- Need to investigate available interfaces for reporting boot/probe times
- Multiple measurement points may be necessary, need to establish a clear definition of "boot" first
- Influenced by defconfig; testing with various kernel configurations recommended
I'm extremely interested in this. I was planning on creating some boot time instrumentation and a boot time test, this summer (before LPC in September). I would be thrilled to talk to other developers about this (either by e-mail, in your bi-weekly call, or at Plumbers) before I get too far into it.
That's great to hear! We're just beginning our investigation by reviewing the available interfaces and assessing how to use them in a potential in-tree test. We would be happy to discuss this further during the testing quality meeting on June 27th, or sooner via email. We'll reach out once we have some ideas to propose and discuss.
If others are working on measuring, testing, or reducing boot time, please consider joining the "Embedded and IOT" micro-conference at Plumbers in September.
One of the chief topics of that micro-conference will be boot time. Please contact me and I can let you know instructions for submitting a topic proposal for the event. (Or just submit something at: https://lpc.events/event/18/abstracts/) The instrumentation and testing of boot time would be a great topic for the micro-conference!!

Thanks for the heads up, we'll keep this in mind!
Best,
Laura
