stable/LTS test report from KernelCI (2023-12-08)

[Gustavo Padovan]

Hello,

As discussed with Greg at LPC, we are starting an iterative process to 
deliver meaningful stable test reports from KernelCI. As Greg pointed 
out, he doesn't look at the current reports sent automatically from 
KernelCI. Those are not clean enough to help the stable release process, 
so we discussed starting over again.

This reporting process is a learning exercise, growing over time. We are 
starting small with data we can verify manually (at first) to make sure 
we are not introducing noise or reporting flakes and false-positives. 
The feedback loop will teach us how to filter the results and report 
with incremental automation of the steps.

Today we are starting with build and boot tests (for the hardware 
platforms in KernelCI with sustained availability over time). Then, at 
every iteration we try to improve it, increasing the coverage and data 
visualization. Feedback is really important. Eventually, we will also 
have this report implemented in the upcoming KernelCI Web Dashboard.

This work is a contribution from Collabora(on behalf of its clients) to 
improve the Kernel Integration as whole. Moving forward, Shreeya Patel, 
from the Collabora team will be taking on the responsibilities of 
delivering these reports.

Without further ado, here's our first report:


## stable-rc HEADs:

Date: 2023-12-08
6.1: 
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/log/?h=45deeed0dade29f16e1949365688ea591c20cf2c
5:15: 
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/log/?h=e5a5d1af708eced93db167ad55998166e9d893e1
5.10: 
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/log/?h=ce575ec88a51a60900cd0995928711df8258820a

* 6.6 stable-rc was not added in KernelCI yet, but we plan to add it 
next week.


## Build failures:

No build failures seen for the stable-rc/queue commit heads for 
6.1/5.15/5.10/5.4  \o/


## Boot failures:

No **new** boot failures seen for the stable-rc/queue commit heads for 
6.1/5.15/5.10/5.4  \o/

(for the time being we are leaving existing failures behind)


## Considerations

All this data is available in the legacy KernelCI Web Dashboard - 
https://linux.kernelci.org/ - but not easily filtered there. The data in 
this report was checked manually. As we evolve this report, we want to 
add traceability of the information, making it really easy for anyone to 
dig deeper for more info, logs, etc.

The report covers  the hardware platforms in KernelCI with sustained 
availability over time - we will detail this further in future reports.

We opted to make the report really simple as you can see above. It is 
just an initial spark. From here your feedback will drive the process. 
So really really tell us what you want to see next. We want FEEDBACK!

Best,

- Gus
