anybody interested in kernel

[dragonLinux]

just want to find someone who has same interesting in kernel developing. qqh!

 

[dragonLinux]

simple question 1: how linux kernel manages physical memory and virtual memory
2: what is the difference of per cpu stack and per thread stack. Which OS is using per thread stack and per cpu stack?

 

[Teddy]

"per CPU stack"? Or, "per process stack"?

 

[dragonLinux]

Is that possible "per process stack"?
cpu1: pid 100 tid 1
cpu2: pid 100 tid 2
cpu3: pid 100 tid 3
how does it run?

 

[tanstaafl]

Windows using per thread stack?

 

[dragonLinux]

I guess "per thread stack" is the most popular model.

 

[Teddy]

Right, I didn't see the "per process stack" model either. Mostly, stack is allocated per thread basis; heap is normally allocated per process basis.

But, never thought the possibility to base stack on a processor...

 

[dragonLinux]

still same case:
cpu1: pid 100 tid 1
cpu2: pid 100 tid 2
cpu3: pid 100 tid 3
Is per cpu stack possible? I am talking about thread kernel state stack, not the userspace stack.

Now I am studying a commercial kernel and its source is opened. Plan is to comment it and if possible to publish a book.
forget the second question probably it is too hard, I still have some problems to understand how it works totally and that is why I need friends to work together.
