Allocation Memory

["Eduardo Júnior" <ihtraum18@xxxxxxxxx>]

Hello,


I asked this once in irc, but I think that I was not clear
I wanna know how does memory allocation for brand new processes work?
In other words, how much of the initial memory is given to this brand new process? How do I calculate this initial amount?

For example:

When I execute firefox application, how much of the initial memory is allocate?

I received in response virtual memory that is allocated to the bin
of my application in question. And that physical allocation is done on
demand. 
 
 This is in fs / binfmt_elf.c 
 

My questions are: 
 
 - The amount of memory for the bin is specified when the creation of the process? Who does that? 
 
 - Initial amount of memory that is flexible? 
 
 - These things are defined only in fs /? 
 
 - Someone has some additional information relevant? 

 - some reference about subject?
