Hello, Since mjt asked about it, I'm posting a first draft of AHCI migration support I recently pieced together. Some more pressing issues came up, including ide-cd being broken with AHCI, so that I have hardly tested this yet.
The initial issue was that the ports were dynamically allocated in ich.c and I did not find prior art dealing with that in VMState. I therefore took the easy path of converting it to a statically-sized array, which is a bit wasteful of course. Better suggestions welcome. The second part then is a mostly mechanical addition of fields and structs to VMState, possibly still incomplete.
