I would like to. While it didn't solve the console difficulties on
OpenSolaris variants, it's probably still a good idea to increment
Sun4u emulation towards being more faithful to hardware. It will take
me a few weeks

Great
I've written up a basic implementation of the SAB 82532 ESCC2 device
and have written a patch for OpenBIOS to add it to the device tree. I
still have the 16550A UART acting as ttya to avoid having to write an
OpenBIOS device driver.
OpenBSD and Solaris both identify the device correctly and

Good idea.
The ESCC device looks like it's written as a sysbus device. I think the
Ultra 5 has no devices on the root sabre bus. The serial controller is
behind the ebus (essentially isa). I'm guessing I would need to write a
wrapper device around the memory io functions so that it can be used

From what I can tell, the SAB 82532 is a bit more
There are two different drivers for the 16550A in OpenSolaris.
There is a generic driver in /usr/src/uts/common/io/asy.c. This driver
clearly states in comments that it is assigning the device to tty[a-d].
It's really obvious to me that there is support in this driver for
using the device for a

Just thought I'd chime in with an update.
We are currently emulating a 16550A UART. The guest sees this as the SU
device, referring to the SuperIO port (a pair of 16550A UARTs). On the
Ultra 5, the machine that Sun4u is modelled against, SuperIO was used
for the keyboard and mouse. The Ultra 5

When configuring devices, Solaris 10 uses the SET_FEATURE command on the CMD646

From what I can tell, this is successful and the emulated IDE controller
