I'm trying to fix a problem with DTrace FBT (it just flat hangs), and want to use the oldest trick in the book -- writing to a known address at various points. Problem I have, though, is that writing to 0x10 virtual, unlike with powerpc32, doesn't write to 0x10 physical. Is there any way to get the mapping for the first page of physical memory, so I can do this debugging? And to make it always available, so that I don't have to worry about mapping it when I need to? Thanks, Justin
