By the way, Norman, what would be a good project for me to get started on while I'm waiting for the people who understand the AHCI and part_blk drivers?

Funny you should say this. I've been building a GPIO driver for the Raspberry Pi, as well as a generic dummy GPIO driver that plays back input events from a list. (So it is possible to write and test programs that require GPIO access without physical GPIO hardware present.)

I'm travelling for the next 7-10 days but will clean and contribute the code after that.

don't wait for it, go for it!

In your prior postings, you stated that you have no experience with
developing device drivers. Well, creating a GPIO driver for the
Raspberry Pi would be the *perfect* way to change that:

* You apparently have an application in mind, which provides you
  with the right incentive.

* The device is relatively simple. So you won't get overwhelmed.

* There is a huge body of public information about this particular
  topic (using GPIOs on the Raspberry Pi) available.

* Others like Jeroen may appreciate your work.

* Within Genode's source tree, there exist GPIO drivers for other
  platforms that you may take as reference.

All it takes is the willingness to learn and to get your hands dirty
with programming.

Regards
Norman
