Just published a deep dive on how we have made it possible to debug the kernel with drgn, without installing any debuginfo packages, on Oracle Linux.
This is a really cool feature that we're in the middle of upstreaming, so it's not quite present in drgn's main branch. However the article has links to all the relevant code, PRs, and issues, so you can see the process in real time, and learn how to get it working on other kernels/distros.
