Hi Korey Sewell or All
I want to customize O3 CPU in ARM and I got a tutorial on gem5 website but that
is for SimpleAtomic CPU. I have to need to know how many modules or program or
file is related with O3 CPU. Korey Sewell , I have seen in max. program written
by you.
Please help me about that and to the point.
1. How many files is related with O3 to customize?
2. How rebuild it?
With best regards

Hi Jagadish,
I think you'll have to actually implement InOrder CPU checkpointing as I am not
aware of anything being checked in that supports that features.
However, the checkpointing functions (serialize/unserialize and drain) in
TimingSimple and O3 should give you a good idea of what you need to make this
work.
Thanks,
Korey

Hello Nilay,
Yes, I could see Ruby being used while checkpointing. When I use the
flags "--debug-flags=ProtocolTrace,RubyGenerated" to confirm the same, I
see the debug output containing the state transitions which look like:
Looking at the code for the in order cpu, it seems to me that you will have to
restore state directly to the inorder cpu, instead of first restoring in to the
timing cpu and then switching to the inorder cpu.
If you still want to do this switch, I suggest you look into how the flag
deferRegistration is used for the o3 cpu.
