Hi everyone,

Just FYI, it's not the best practice to modify files in src/ (e.g.,
src/mem/cache/Cache.py) if you want to change a parameter. Those are
*source* files. Everything in those files can be overridden in the *python
configuration* files. You can simply change something in your config file
if you want to change a parameter. *You should only modify files in src/ if
you are changing or creating new models.*

Hopefully, you'll be seeing some new code in gem5 this summer which will
make this even easier :D.

Cheers,
Jason

Hi Ahmed,

You could either follow Abhishek's advice and use default configuration
scripts (se.py or fs.py) or you can create your own script to manipulate
those options. Writing your own configuration script is recommended (You
can check this  book to learn how to do
that). You can change the latency of cache and memory by changing
src/mem/cache/Cache.py
 and
src/mem/DRAMCtrl.py

 respectively.

Best,
Muhammet

Hey.

You can change those parameters for classic cache in config/common/Caches.py
For main memory search for python files in src/mem/ directory, mostly it’s
DRAMCtlr.py file
