Hi Gabe,
You can use 9p and VirtiIO for this. There is a 9p implementation in
gem5 that uses diod (you'll have to install the diod package).
There is an old, and probably broken, description on the Wiki:
http://gem5.org/WA-gem5
The modern Arm platforms come with two unused VirtIO MMIO devices that
you could use for this if you want to avoid PCI for some reason.
Cheers,
Andreas

Hi Gabe,
I don't have any recollection that this is supported (though it would be
very cool). Then again, I'm often finding gem5 features that I didn't know
existed, so I could be wrong.

Hi folks. I should already know the answer to this, but I can't seem to
find the emails, etc, that I had intended to read later which talked about
this. Is there a way to mount bits of the host OS within the simulated
system? I saw an email or maybe a wiki page talking about a technology or
FS or something which made that work, but now I can't find where that was.
Any tips would be appreciated.
Gabe
