Thanks, I investigated this and it's enough to drive me insane. It could be
that I'm lacking the intelligence. It seems to me that OpenBSD does some
assumptions inside OF_getprop() that is called from zs.c line 1035.
In particular with offsets to property names. I compared the firmware from
QEMU with my G5 and there is a difference which I'm now compiling a patch for.
Since I'm also doing a backup at the same time it may take longer than usual.
Here is what I'm seeing in QEMU:
0 > cd /aliases ok
0 > cd sccb ok
0 > .properties
name "ch-b"
device_type "serial"
compatible "chrp,es3"
reg 00013000 00000001
00013010 00000001
00013040 00000001
00008600 00000100
00008700 00000100
interrupts -- 18 : 00 00 00 24 00 00 00 01 00 00 00 06 00 00 00
00 00 00 00 07 00 00 00 00
slot-names 0
interrupt-parent fff66674
ok
And what I'm seeing in my Apple G5 is different. There is a "built-in"
property between the compatible and the reg property. I'm trying to insert
this property in the QEMU with a patch like said above. If you want to follow
this on your hardware the commands are a little different I photographed it
on my ipod but it would mean I turn on my access point to upload it so I'll
just list the commands.
dev /aliases
dev sccb
.properties
There you'll see the difference. I'll report back if my patch works.
