I think I managed booting Tribblix under the QEMU niagara target. It
has less devices than sun4u, but the console was working.

TL;DR: When QEMU is launched with VNC as the output and viewed with a
client that defaults to zlib VNC encoding, the resulting output tends to
accumulate artifacts.
Reproduction:

ory controller. I think it's not implemented. Or at least wasn't
back then.
And since I wanted to be compatible with the real hw, which doesn't
have a fw device, I just kept the hardcoded value in OFW.
If it's in the MC meanwhile, I can add the check to OFW as well.

I used both in my AIX experiments and AIX seemed to be happy about it.
But maybe AIX simply doesn't care as long as the residual data is correct.

Please correct the typo in the subject. I was scared that someone dug

In the particular case of sun4u, I think the proper way is not to have
the read callback, but throw an 'Unassigned memory access' exception

are in the list above. The Micro- and Super- SPARC
entries are not supposed to be there because they are 32 bit CPUs and
thus not compatible with qemu-sparc64.
Works as designed.
