hi Mike,
i tried that already on a 2.2.18 kernel and
num_physpages is not
exported. num_physpages does not contain the
actual RAM present
in the system.

i booted up my linux with command line parameter mem=32M,
but my machine actually had 128M RAM. and from KDB i inspected
num_physpages which showed me only 32M

thanx

Hi,
Is there a way to know the amount of physical RAM
present in the system from a loadable kernel
module
Yes.. num_physpages is an exported symbol.
