I have tested the run script run/ahci (os/run/ahci) on both foc-x86_64 and fiasco-x86. It doesn't work on either platform. In the "Limitations and Known Issues" section of the README, it does mention that it won't work properly on real hardware or on Fiasco.OC, but it also doesn't work on Fiasco in qemu. I would very much like AHCI to work on Fiasco.OC on real hardware. Can someone who understands the problems fix it? (Or teach me enough so I can fix it; note that all my experience with Genode is in configuration, not actual programming, and that I'm not familiar with OS development.)

The README is a bit of outdated I guess. The driver runs on real hardware on both Fiasco as well as the OC version. It will not work for these kernels within Qemu, because there are issues with the interrupt level/polarity settings and the ACPI tables of Qemu. I have already fixed that a number of times, but I don't regard the Qemu support as a good option anymore because there are too many changes with each Qemu version. If you want to fix it for your Qemu version, have a look at 'repos/base-foc/src/core/irq_session_component.cc' and contrib/foc-<hash>/src/kernel/foc/l4/pkg/l4sys/include/icu.h', that would be appreciated.

Just a quick note: We have very good experience with Qemu 1.5 and 1.6 but up to know do not support more recent versions because of the always reoccuring issues with device models.

True, but AHCI will not work there on base-foc (I am using Qemu 1.5.1), haven't tested base-fiasco lately, it might work without IPAPIC. On the other, base-nova should work.

Okay. I'll try it on my computer (and on VirtualBox). Thanks for telling me. I thought that I'd have to wait to be able to run Genode on my computer. Now the only hardware support missing (that I'm aware of) beside the proper configuration is wireless (with WPA2-PSK support) and printer support.
