There is a nvram. But the proprietary firmware OBP - uses a different
layout than OpenBIOS. The current implementation of nvram doesn't
persist its content after shutting down or a hard reset. But, for your
experiments a soft-reset should be enough. Just use the 'reset'
command from the OBP ok prompt.
It should be possible to add some code to qemu that it would
read/write the contents of the nvram to a file.

Yes. ss5.bin is a copy of a real PROM.

We can not, because the layout is different.

None that I know of. If you have to use the proprietary firmware
(ss5.bin, ss20.bin and so on), I think extending qemu that it persists
nvram is the way to go. I think the initialization of the nvram
happens in sun4m.c. At least it used to be there. You'd have to add
some option like -nvram=file.bin which would disable -prom-env
options.

I think so. Except that I'm not sure you have to modify escc.c. But
I'm sitting at the airport and don't have qemu sources handy.

An ESCC port has two channels (physical ports) which are called 'a' and 'b'.

Hi Artyom,
Thanks for your answer from the airport... where are you bond to?

OK, great info. I might try this when I will succeed getting new
serial port to the prom.

Well, I thought I had to had fields to the escc_init function because
I was understanding qemu_irq & CharDriverState fields as ttya and ttyb
description. But I understand from your answser that I was confused by
the a & b channel for an escc port?
But then where are the two intitialisation of ttya and ttyb?
I think I lack understanting of this:
slavio_serial_ms_kbd_init(hwdef->ms_kb_base, slavio_irq[14],
display_type == DT_NOGRAPHIC, ESCC_CLOCK, 1);
// Slavio TTYA (base+4, Linux ttyS0) is the first Qemu serial device
// Slavio TTYB (base+0, Linux ttyS1) is the second Qemu serial device
escc_init(hwdef->serial_base, slavio_irq[15], slavio_irq[15],
serial_hds[0], serial_hds[1], ESCC_CLOCK, 1);
Especially the coment (no much comment in there :-) ) base+4 and
base+0. I can't see where this is defined. I attached the sources if
you are getting bored in the airport... ;-)
Thanks again. Have a nice flight.
Jean Michel

* On Sparc32 this is the serial port, mouse and keyboard part of chip STP2001

* http://www.ibiblio.org/pub/historic-linux/early-ports/Sparc/NCR/NCR89C105.txt
*
* The serial ports implement full AMD AM8530 or Zilog Z8530 chips,
* mouse and keyboard ports don't implement all functions and they are
* only asynchronous. There is no DMA.
*
* Z85C30 is also used on PowerMacs. There are some small differences
* between Sparc version (sunzilog) and PowerMac (pmac):
* Offset between control and data registers
* There is some kind of lockup bug, but we can ignore it
* CTS is inverted
* DMA on pmac using DBDMA chip
* pmac can do IRDA and faster rates, sunzilog can only do 38400
* pmac baud rate generator clock is 3.6864 MHz, sunzilog 4.9152 MHz

Arg! Unfortunately I think it is beyond my competences but I will give a
try. Another way would be to push Bob's upgrades, among them cg3.c to
the update qemu. So we could use openbios as Mark said and pass the
command in the script.

OK so it's like one Zylog port with two channels..?

OK, I got the comment but I cannot see where this is done. I mean where
is it define in the code that base+4 address. The only parameter which
is passed to escc_init is base.

Now that I had got the network working through a bridge, I have started
work on this issue this afternoon.

? I'll have a look at sun4u.c
