Hi Murat,
1) As far as I am aware, only PIPT caches are implemented in gem5 (arguably the
L1 can be VIPT as a result of using the correct combination of
associativity/number of sets and page size). If you want a virtual cache,
you'll have to implement it yourself, and this is not going to be trivial if
you want coherence to work, I reckon.
2) Nothing particular, I would say.
Arthur.
