Hi all,
my project is to write a simulated network card. It will comunicate with a
SystemC emulated device, a cirrus logic cs8900a. The logical scheme is circa
as it:

QEMU <--> WRITTEN DEVICE <-- socket --> SystemC description of the cirrus.

The connection between the qemu device and the cirrus is via socket. I
started to write the device taking the parallel description as example, but
I guess that is more complex than parallel but more easy than the ne2000
description.

-I think I need to write the read and write functions as
mydev_ioport_read/write and there must be the transmission with the systemC
description and register them in the function "table" with
register_ioport... in init function.

-I need to write a mydev_init function that is called at qemu init in vl.c.
but i think that I must use my device as a pci device and i need to
"configure" it right? can someone help me about this point?

-finally I must to iniziated it in vl.c and vl.h and modified the make
script.

Thanks for the help!

Ale
