Subject: Linux kernel memory and split on 64-bit machines
Date: Mon, 29 Oct 2007 13:20:11 +0200	[thread overview]
Message-ID: <4725C1EB.10205@checkpoint.com> (raw)

Hi,


I am researching now about the Linux kernel memory on 64-bit (x86_64) 
machines. I am looking into answering the following questions:

1. Is there a user-kernel split on 64-bit memories? If so, how is it 
done? What is the size of each part?

2. Does kernel high memory exists on 64-bit machines?

3. How is it possible to detect in runtime the split and the size of the 
physical memory?


Thanks,


Yoav
