Hi Mrinmoy,
Would you be referring to page faults on the host machine, or page
faults on the target machine?
For the former:
Ruby queries its host machine when stats are dumped for the number of
page faults encoutered during simulation, but it is not "aware" of a
page fault on its host as it occurs.
For the latter:
Ruby is not directly aware of paging activity on its target. Since
paging is a system-level phenomenon, you might be able to caputre paging
with a Simics hap callback (see the Simics Reference Manual and the
Simics Programming Guide for details), or possibly by observing the
dynamic instruction stream and signaling when a parcicular physical PC
is reached.
Regards,
Dan Gibson

Hi,
I was interested to know, if ruby memory module signals Page
Faults, and if yes, some pointers in the code as to how or where this is
done.
