How may bits are used for logical address?


Hi guys,

You are all know, the Linux's Logical address translation.
Logical address -> Linear address -> Physical address.

My doubt is how may bits are used for Logical address? in both 32-bits & 64-bits addressing.

Logical address -> Linear address -> Physical address.
32 (default) 32 -> 32 -> 32
32 (PAE) 32 -> 32 -> larger than 32 (when PAE is enabled, hardware dependent)
64 (default) 64 -> 64 -> 64 (most systems only use 40+ bits only, the leading bits are zero. Still 64 bits are reserved for addresses)

And if a mod has said the thread is reported for closure it's
always prudent not to respond to that thread ...



Cheers,
