Physical memory allocation

Post by Veksler Michae » Sun, 30 Aug 1998 04:00:00



Is there a way to let a user space process allocate required physical
memory? Should I write a device driver and mmap it?

I need this to write a memory tester that will operate from linux.
(I have seen memtest86, and I am not impressed. It would be nice to
have something that comes close to "make zImage").

So do a "make zImage" :-).

Anyway, I don't know the answer to your real question.

A conclusion is simply the place where you got tired of thinking.

 
 
 

1. Physical memory allocation?

I found the VM easily (vmstat) and quite frankly I think something is very
screwy; out of a 500MB swap slice, I only have 11MB free, thus making me
think KDE may have a memory leak.

I remember with sar from OSR saradm or the likes (Hm, seems my memory is
failing me) could be used to an extent to get an idea on the memory
utilisation.

Is it the same story under S8?
