Hi Eliot,
thanks for the advice. The component (class) I'm looking for is the one that
uses
the page table walker (which uses TLB inside) to convert a vaddr to a paddr.
What I want to do is to modify a given virtual address to a different address
if it is in
a specific range, to mimic memory region remapping without changing the
application
binary and/or the source code. I need to insert code to do this address
modification
where vaddr is about to be passed to the page table walker.
Best regrads,
Soramichi
