build-configs.yaml: Add kcidebug fragment #2580

Closed nuclearcat closed 3 months ago

nuclearcat commented 3 months ago

It might be useful to enable lightweight(relatively) kernel debug options.

This looks like it might be useful, we might need to pare some of these depending on how bad the performance is.

Might also be worth taking a look at https://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git/log/?h=testing/v6.10-rc3 which is a similar idea.

I'm implementing what I recall from using these settings on heavily loaded semi-production servers. I plan to experiment with adding and removing more options. Additionally, I need to align the basic defconfig with defconfig+kcidebug in terms of device coverage, as we're currently testing only a few devices for defconfig.

It might also be beneficial to integrate support for measurements, such as boot time, into KernelCI to evaluate such performance overhead.
