Hi Artyom,

Hi Artyom,

Thanks again for your interest.

Hello Artyom,

Thanks for taking time to consider my needs for serial ports.

I went on board Thalassa this morning and started the system (not easy, the
ship is laid along quay hardly powered). I gathered the informations you
requested. Hope this is all you need. Please ask me if I missed something.
I also attach the documentation of the board.

Thanks, this looks interesting. What I wonder is where are those
serial ports in the device tree?
Are they connected to the VME-BUS, and OBP knows nothing about them?
Do you know how does the SunOS find them?

Great step forward yesterday. I can now pass a serial port to the guest SS5, rename the device ttya to the expected name and then I can communicate with the software!!! This is really great!
So I come back to you about your proposal to add serials ports to the emulated ss5. This is just what I need now to go forward.
Could you please just give me the start point so hopefully I could give a try? Does only sun4m and escc.c need to be modified? Or is that much more complex?

Thank you for your answer. I am now so close to succeed !
(well, still need network, haven't had a look at that issue yet)

Kind regards,
Jean Michel

Hello Bob,

Of course, with your full custom 0.15.50 tree it is much much better!! Got
the zip file and configure only sparc-softmmu. I undesrtand my mistake. I
thought I needed only the new files from the 0.15.
Thanks you for that!!

Now I need at least 4 real serial port from the host up to the guest....
...and network.

Network must be there. The lance ethernet is emulated (except for some
test/loopback registers, but SunOS can live without those).
As for the serial ports, one way to proceed may be adding your
machine/board to qemu.

Can you provide the OBP device tree of your machine?
It can be done in the OBP "ok" prompt like this:

ok show-devs
<the device tree will be shown>
ok cd /
ok .attributes
<attributes of the root device will be shown>
ok cd <some device path from the device tree above>
ok .attributes

The "ok " parts above would come from the OBP, you don't need to enter them.

If this listing shows that the machine is close to SS-5 or SS-20,
adding more serial ports should be easy.

Works with SS5. With SS20, I have an error saying that it can't find cpu
definitions..? (was working with other verions). see tomorrow.

Have you tried -cpu "TI SuperSparc 60" ?
