We do not provide command line options for all the parameters that can be set. Instead we make use of the simulation scripts. You can edit the simulation script, se.py or fs.py (which ever one you are using) to set the bus width. You can read more about simulation scripts on gem5.org. -- Nilay _______________________________________________ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
