Runnable stuff:

* https://lwn.net/Kernel/LDD3/ the best book, but outdated. Updated source: https://github.com/martinezjavier/ldd3 But examples non-minimal and take too much brain power to understand.
* https://github.com/satoru-takeuchi/elkdat manual build process without Buildroot, very few and simple kernel modules
* https://github.com/tinyclub/linux-lab Buildroot based, no kernel modules?
* https://github.com/agelastic/eudyptula
* https://github.com/linux-kernel-labs Yocto based, source inside a kernel fork subdir: https://github.com/linux-kernel-labs/linux/tree/f08b9e4238dfc612a9d019e3705bd906930057fc/tools/labs which the author would like to upstream https://www.reddit.com/r/programming/comments/79w2q9/linux_device_driver_labs_the_linux_kernel/dp6of43/
* Android AOSP: https://stackoverflow.com/questions/1809774/how-to-compile-the-android-aosp-kernel-and-test-it-with-the-android-emulator/48310014#48310014 AOSP is basically a uber bloated Buildroot, Android is Linux based, and QEMU is the emulator backend.
