We have now two kdevops proof of concepts with kernel-patches-daemon [0], one for Linux kernel modules testing [1] and the other with radix tree testing (xarray, maple tree) [2]. These trees just contain the required .github/workflows/* files used to trigger a github self-hosted runner to run kdevops since evaluation shows that using github hosted runners will just not work or scale for Linux kernel testing [3]. The way this works with KPD is that KPD has an app in the linux-kdevops organization which is in charge of taking patch series posted to your respective subsystem patchwork (you can have dedicated filters on a mailing list for only specific files if you don't have a dedicated mailing list), it creates a git tree branch using your configured KPD main development tree source, and pushes it out to a respective test tree under github for for you. For example, in the case of development for Linux modules it pushes out a branch with a delta onto the linux-modules-kpd tree [4] and in it, it will also merge the latest kdevops-ci-modules [1] work, which is where the github runner work gets developed. For the radix tree we currently do not yet have a patchwork instance defined but we *could*, and the way it would work is that KPD would push out a branch into the linux-radix-tree-kpd [5] tree with the github actions defined in its respective kdevops-ci-radix-tree [3] tree. What these PoC shows is that the way kdevops has designed testing selftests is that we actually only need to differ in *one* single line of code on the github actions runner to test either of these two Linux kernel subsystems: the defconfig used. To be able to *share* the *same* Linux kernel github actions runner code development between the Linux kernel module tests and the radix tree, all we need to do then is use the git tree onto which a delta was pushed onto as the source for the defconfig. So all we have to do now is just add a symlink of the respective development test tree onto its corresponding defconfig. Add the respective defconfig then for linux-modules-kpd by symlinking it to the seltests-kmod-cli defconfig. This will let us later share *one* github development action runner code for self-hosted runners for *all* Linux kernel sefltests we define in *one* development tree which KPD could leverage. Now that we have locked down the linux-kdevops github organization to only allow respective developers to be able to trigger pushes or PRs, this also allows us to add dedicated self-hosted runners per target test development repository so we can scale our testing as we need with security in mind. The only thing left to do here now, is to evaluate if we want an allow check for who's patches we want to enable automatic testing for through KPD.
