Re: [help] How to test kernel code that I wrote?

Is that I'll need to use VM to test the code, or just test it on my laptop?

I found that if sometimes I broke my code (e.g. can't remove modules, modules panic ...etc) I need to reboot my laptop to recover from this situation.

Is that how a true kernel developer does? or they will open a VM to test it, then test on real hardware PC.

There's no such thing as a "true kernel developer". Some run their code in a VM because their code is something that can be tested in a VM, some test on a real hardware PC, some write the build onto a flash card and put it in a non-PC system (usually an ARM or MIPS based embedded device). All depends what your resources are, and what code you're testing.
