Hi Myles,
Here's my quick patch to qemu to dump out the address where the write is
failing:
Index: vl.c
===================================================================
--- vl.c (revision 6426)
+++ vl.c (working copy)
@@ -389,7 +389,7 @@
for(i = start; i < start + length; i += size) {
ioport_write_table[bsize][i] = func;
if (ioport_opaque[i] != NULL && ioport_opaque[i] != opaque)
- hw_error("register_ioport_write: invalid opaque");
+ hw_error("register_ioport_write: invalid opaque: (start
0x%x, length 0x%x, address 0x%x)", start, length, i);
ioport_opaque[i] = opaque;
}
return 0;
And here is the result output:
qemu: hardware error: register_ioport_write: invalid opaque: (start
0x510, length 0x1, address 0x510)
HTH,
Mark.
