qemu is a good way to experience with kernel hacking
Hopefully someone can update the LDD(linux device driver) and Linux kernel books. In fact Linux Foundation should sponsor such efforts since technical book like this is hard to make any profit.
The wireguard test suite that’s now in the kernel is an excellent way to experiment with using qemu to develop kernel modules and also do automated tests.
See also The Linux Memory Manager: https://linuxmemory.org/chapters Last update the author sent out was in early July noting that the book is now in editing:
> I am happy to report that I have completed the first draft of the book [...]

I cannot remember (or find) where I signed up for updates, but I get an email every 6 months (or so) from Lorenzo Stoakes personal email. Probably just send him an e-mail and he'll add you to his list.
