With that said
For x86 O3CPU, the multi program workload simulation is also broken.
So basically one can not multi core simulation using x86 O3CPU with and
without SMT.
Also, to all developers who push commit to gem5, please do thorough testing
as both of this support was working in older commits!
Hi all,
I believe there is indeed at least one bug in O3 CPU implementation when
using SMT in SE mode. Namely, the rename mapping for the zero register on
additional threads fails assert(prev_reg->isZeroReg()) in rename() in
/src/cpu/o3/rename_map.cc. This is because the processor logic does not

Hi Abhishek,
I think when you check *m5out/config.ini*, you should look at
*switch.cpu* instead of *system.cpu*.
System.cpu is always initialized to AtomicSimpleCPU by se.py.
Switch.cpu is the one you indicate in options and the one whose stats
you should be looking at.

Hi Abhishek,
SMT is not something that is normally tested. I expect that this is a
problem with se.py (and the 10s of other python files that it uses...). I
suggest making a config script from scratch like in Learning gem5 so you
know exactly what configuration you're running. You should be able t
