Hi Tariq, The way SimObject parameters work is explained in Part 2 of Learning gem5 <http://learning.gem5.org/> here: http://learning.gem5.org/book/part2/parameters.html. It's a little convoluted (you have to go through python to set parameters), but it is incredibly flexible.
The *defaults* for these parameters, specifically, can be found in src/cpu/o3/O3CPU.py. Of course, if you want to change these parameters you should do it in your Python config/run script. The best way is to derive a new class from DerivO3CPU and extend it with your own values for the parameters. Or, if you want to get fancy, you can add command-line parameters for the CPU parameters you want to change dynamically.
