before set the configerations, you need to set the kernel then only it will override the exiting configurations other wise it will give same configuration whatever you will specify.
these is happening in X86 , may it is applicable for ARM > Hello, > > > I'm new to gem5 and trying to establish simulation environment of three > level caches with different cache line size using gem5. > I have managed to modify some codes and configurations of gem5.
