Welcome!
Currently i am searching for some bugs which can help me in
understanding Haiku internals.
Lucky for you we have planted quite a lot of them over the years :-)
If you want to get dirty with driver development directly, you'll probably
find some equipment or device that doesn't yet work with Haiku flawlessly or
not at all.
Another option would be to add a missing feature to an existing driver, for
example the AHCI driver doesn't support command queuing yet.
There also isn't an NVMe driver yet; porting an existing driver, or writing
one from specs can also be a satisfying experience :-)
Working directly with the hardware is a lot trial and error, though, but
some people certainly like working on that level.
A bit further from the metal would be stuff in the kernel, for example
search for a simple (read: easily reproducible) bug, and try to find its
root cause. Following the code paths involved is a good way to get
accustomed to the source code.
If you're into optimization, there is lots of stuff that you can time, and
improve considerably (be sure to disable kernel debugging mode, though) :-)
Also, you should spend some time on your development environment when you
picked something of interest; for example, if possible, you should always
work in emulation when doing kernel development. It speeds up the
development/test rounds considerably. It's also great to be able to see both
sides of a device. But for driver development, you often have to use a real
machine -- in that case, setting up a PXE network booting environment is the
best way to lower the turnaround times (although, IIRC in that case your
first job would be to get that to work again).
Anyway, have fun!
Bye,
Axel.
