hi,Gleb O. Raiko£¬ Do you mean change p6032 setting or change those interfaces? To make more drivers and userland apps like X happy,it seems better to make both address space consistent.And since current code seems to assume same CPU & PCI space,this may make Ralf happy if someday he accept the code:). Just that I am not sure the setting can be freely changed.Will try later.
