[Qemu-devel] SystemC hw simulation in qemu

Hi all,
I've tried to create my simple hw and it's ok. Now my teacher tells me that
i must use a hw description written in SystemC and plug in Qemu.
Have you got any idea to do it? Can somebody link me to documents where I
can find info?

Hi,

If you do that I am interested to see the results. Use a simple device 
such as the serial port (hw/serial.c) as an example.

Fabrice.

The idea is to create a SystemC wrapper file in hw dir, where there is the
code for connect via socket to a SystemC process in host machine. The
problem is that I write my simple hw, but instead use io address such as
0x378 i need to use memory address, so I can use it in every virtualizzation
(i386, mips etc...).
Where can I look for it?

Thanks
Ale

Why do you want to have SystemC in its own process?

BTW, SystemC freely available lib is really slow.  Take a look at
some lookalikes such as FastSysC.

It can be an idea, but I'm not the systemc developer, I've already got the
sc module, and I must integrate it into qemu. This is that I must to do for
thesis' degree.

Thanks

Can someone help me about this? I've looked at exec.c source for understand
how io memory addressment go but i don't know if it's the right place to
start.
I see that in serial.c source there are IO and memory map function for read
and write, and serial_mm_read/write functions use serial_read/write
functions. The difference is the base address I see... right? Where I can
find this IO address?
And there is a serial_mm_init function. Is it used only all emulation except
i386 or can I use it for i386 too? In other words... can I use IO memory
address for serial port in 386 emulation or not?

Thanks
Ale

Ps: Be patience, I am only a poor student ;)
