Use of Kas menu in CI system

[Kari Argillander]

Hello.

I'm thinking what should be right way to generate config without human interaction.
We use KAS menu for selecting different projects / targets / machines. This is all handy
when human does it, but I'm struggling to figure out how CI system should do this.
When I do this in kernel I use kernel scripts/config tool to enable some parameters what
I'm interested and then generate default config based on those.

With Kas I do not know how to auto generate these. Right now I manually generate
each config with Kas menu and save generated config to directory and CI use these.
Does any of you guys have any better idea how to do this.

Also can KAS select multiple targets same time with menu? I think some version KAS
did support list for targets, but I'm not really sure. Yocto does support multiple targets,
but I have not manage to do this with KAS. I use version 3.0.2.

kas menu was designed as kind of a replacement for "kas build
kas.yaml:opt1.yaml:opt2:yaml:...". So, if you want to run specific
selections of the menu resulting in a .config.yaml in CI, you just need
to translate the inclusion in that .config.yaml back to a kas build
command line.

Example:
https://gitlab.com/cip-project/cip-core/isar-cip-core/-/blob/master/.gitlab-ci.yml

Granted, that will not work that easily for free-text values entered in
the menu. Those would require a special yaml file to inject them - or
pick them up from CI-defined environment variable.

Yes, you can, see e.g.

https://github.com/siemens/jailhouse-images/blob/master/Kconfig
https://github.com/siemens/jailhouse-images/blob/master/.gitlab-ci.yml

Also this works:

kas build kas.yaml --target mc:multiconf1 --target mc:multiconf2 ...
