[Qemu-devel] Fwd: Cosimulation

[Alessandro Corradi]

Hi Nicolas,
Thank you for reply! The "only" trouble is that I need to descrive it as a pci device. Taking the parallel port as an example is  very usefull for  simple  hardware  as you  made.  But I need some info for write my device into qemu, in particular the init function for pci device as the ne2000 (In init function of network card it set pci_conf, should I need to set up? And what arguments should I put in pci_register_io_region function?).
My emulated device for the moment need to run in i386 architeture so I have not to be completeness about cpu target etc... 
Anyway I appreciate if you can send me your written device so I can see if it can help me!

Thanks

Ale

Hi Alessandro,

Concerning your cosimulation problem, I may help a little bit,
because when you first posted on the qemu dev list about your sysc project,
it motivated me to first learn about systemc (which I didn't know) and to
start hacking qemu to connect them together.

Well I must admit I'm pretty satisfied of the results,
I managed to build some small sysc dumb devices (gates, counters,
ram/buffers, fpu etc..)
(with a FIR filter in mind indeed), defined some sort of sysc written
"interface" that offers a bus+signals to sysc, while connecting to qemu
via a socket.
Within qemu, I created a parallel-like device (as you said on the ml
recently) and so I can probe my device from within guest OS (dos, linux,
etc..)
the device is called remote.c (like a "remote" parallel-like device)

If you want I can send you some rough version of my project to see how
(ugly) I did
and maybe we can share our experiences...

Regards,

NS.
