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. |
