[Qemu-devel] sparc memory/io mapping (and a milliseconds counter)

is there a generic way to find out mapped device for a virtual
address? Or at least its physical address?

ok see get-msecs
value get-msecs    ( Parameter field: 7680000 )

ok 7680000 map?
Virtual  : 0768.0000
Context  : @ 0.1ffc.0000  01ff.afc1 # 0
Region   : @ 0.1ffa.fc1c  0000.0000 Invalid

ok 7680000 iomap?
Virtual  : 0768.0000 is not a valid I/O address.

Looks like the address 0x7680000 is not mapped to anything, but the
call returns a value:

ok get-msecs .
ok get-msecs .

The value is obviously wrong, but the question is, where does it come
from? Is it a RAM or is it one of devices? Didn't see anything similar
in prtconf dumps.

Another related question is, are there any known issues related to
milliseconds counter?
In the current OpenBIOS "get-msecs" call doesn't return anything at all.
