Hi guys,
I am asking silly doubt. Why embedded linux not having swap partition, I
have scened many embedded distros(debian6, ubuntu,open embedded). All have
doe's not have swap partition. when I try to install with X86 it's
mandatory swap will there. please guide me guys.
-Ganesh.
Did I learn

AFAIK you don't need Virtual

- From a design perspective, the design team will know how much RAM is
required for a purpose built embedded device. This amount of RAM would

Swap memory is concerned with paging.

Paging is part of Virtual Memory. Page tables maintain the mapping between
the Virtual Memory and the Physical Memory.
You have virtual memory in embedded system.

In general, very few embedded systems really need deterministic operation.
Irrespective of virtual memory support,

Don't applications/processes on embedded system have their own dedicated
address space ? I would think having dedicated address space requires

Pardon me, I don't have any knowledge on Embedded system architecture. :)
non deterministic is CS lingo for unpredictable. Assume you are accessing
a memory
This thread is full of theoretical stuff, lot of useful info but
nowadays I only deal with practical reality.
That is the single biggest problem with the people I meet here in LUG.
You have to get practical doubts.
Theory is fine but we have to grow beyond that.
I have worked on few embedded

Can you explain the difference? How far is it
I must thank the OP for bringing up this question because
after posting my earlier response I wanted to understand
this in more detail and found this gem:

Interesting article, thanks for sharing.
