Storage device considerations

Hi Folks,

starting to discover the possibilities of using storage devices under
genode, a few questions arised:

(1) AHCI is declared non-working on Fiasco.OC and NOVA. Is this
planned to be resolved in the near future?
(2) USB Storage is supporting only one device. Are there plans to extend this?
(3) Using the part_blk service, it is possible to redirect children to
different partitions of the same storage device. What I'm interested
in is somehow the inverse. Is it even possible for a child to get
access to multiple block devices? I think it is quite a limiting
constraint if a child can only access one single storage device.

The background for this question is of course the Vancouver port. I
was able to give the guest VM access to exactly one storage device
through the Block Session Interface of the USB service. However, as
soon as the VM is configured to use a second device, the existing
infrastructure does not allow that (or I haven't found the proper

So, I would like to open the discussion on this topic to see where the
path could lead.
