Internals: What are the different memory limits in 64bit mode

josbar742 · 06-10-2009, 04:09 PM

I am interested if anyone has already done the work, or know what the different memory limits are for 64bit kernels.

Specifically I am interested in intel based architecture (AMD too) and how much low memory is allocated, how must is allotted for slab, etc.

Thanks in advance!

It's not obvious what you are asking. Try these to start with

Code:

cat /proc/meminfo
cat /proc/zoneinfo
