RTM copies the trace info from ASID 4 to the dump. If you want to look at the raw buffers, I think you'd need to find some way to include ASID 4 in the dump and get to the buffers via control reg 12 and figure out how to convert the real address to a virtual. I now remember looking at IHATTE for some reason and that's the macro for mapping the trace entries. Most of this stuff isn't GUPI.
