Curious to know the coolest things you achieved by configuring your kernel. I know kernel config can be boring, but I'm hoping someone will have an impressive answer.
For me I have a very lightweight kernel that runs wayland on nvidia without any issues to date.
Gotta admit, it was very hard to setup initially.
However it's been working perfectly ever since I did.
Been using it for about a year or 2 now.
Also when I linked the Arch wiki,
I noticed in it's article that there's now a gpu-passthrough-manager,
which will likely make the process of setting up a little bit easier.
