Hi Joram,
It is possible, however there are some caveats.
1) The way that cores are brought online with the realview platform
relies on cache maintenance operations that we don't support. Thus, to
boot the system you must start it with an atomic cpu and no caches. As
soon as all cores come on line (a few seconds after boot when all the
CPUn: lines are printed) you can then take a checkpoint or switch to a
more detailed model and caches.
2) The support is relatively new, so there may be issues that haven't
been uncovered yet.
Thanks,
Ali

Hi all,
I would just like to get some clarification on gem5's features for
the ARM_FS build, specifically multi-core support.
It says on the gem.org main page that ARM_FS mode supports only one
core:
"ARM: The gem5 simulator can model a single core of a Realview ARM
development board..."
However in the latest ISCA 2011 presentation slides on page ~101 it
says that ARM full system supports up to four cores.
So I was just wondering which source is correct - is it now possible
to run ARM full system simulations using four cores? Or is this just
something which is in development?
Thanks,
Joram Benham
