Hi all,
I adopt gem5 in SE plus Ruby mode. I want to warm up cache before data
measurement. During my experiment, I found the '-W' option does not work. The
simulation process is controlled in Ruby mode from scratch instead of after
<N> instructions as expected. I check the file /config/common/Simulation.py/
and it seems that '-W' is only invalid when '-s' is also specified. However,
once I plus '-s' option, the simulation is aborted and it throws an exception
as following,
info: Entering event queue @ 0. Starting simulation...
hack: be nice to actually delete the event here
Switched CPUS @ tick 54500
Changing memory mode to timing
System already in target mode. Memory mode unchanged.

gem5.opt: build/ALPHA_MESI_CMP_directory/cpu/simple/timing.cc:159: virtual
void TimingSimpleCPU::switchOut(): Assertion `_status ==
BaseSimpleCPU::Running || _status == Idle' failed.
Program aborted at cycle 54500
According to the above exception, I reviewed the '_status' and it equals to
BaseSimpleCPU::IcacheWaitResponse. I have no idea about this bug.
What version of gem5 are you using?
