Hi,
I would like to know if the Virtual Memory addressing is
still going to be used in an environment with out any disk/Swap-space.
The reason I ask this is because, I think that the main point to having
this Virtual memory is to make the processes re-locatable on the RAM and
to support the Demand-Paging concept. If there is no swap-space in the
first place to begin with, is there a need to still have this scheme? Do
all processes + kernel run in Real Mode instead?
Or is it that the Protected-mode (with Virtual Memory) is still used but
the mapping from Virtual Address to Physical is more one-to-one? And the
4 Gb Virtual Address space in any conventional system is not applicable
to this kind of a situation.
Regards,
Aravind.
