Hi Alessandro,

Ah OK, I see, your project seems to be way more ambitious than
mine :-)
So my project may not help you as much as you could expect..
Maybe only the sysc/tcpip glue mechanism..

Anyway, attached is a tarball of my project, containing a
patch against qemu-snapshot-2006-07-23_23 (I can provide it if
it fails to patch against more recent versions) plus the
directory related to sysc.

See sysc/README for more info..

Will be interested by your return.. and also by your PCI/sysc
experiments also..
tell me if you manage to compile/run it (watch out the sysc
signal trace log which is generated)

Can send me something from your project, just by curiosity ? :-)
I would be particularly interested by other sysc/qemu glue
mechanism, and also to see if you managed to generate
interrupts from sysc, and handled within qemu guest OS...

Good luck for your project,

NS.

ps: oops, I was not supposed to send my professional signature
in the mail I sent you (fwd to the ML), well nevermind, I'll
use another mail identity from now on.. :-)
pps: I also fwd it to the ML, in order for other interested
people to have a look at it if anyone is interested..
