I solved the issue. The MinorCPU should be added to CPU_MODELS in the *build_opts/X86. *Now the problem is that the simulation crashes when I run multicores. Seems like MinorCPU doesn't support multicore. It keeps generating following error:
* command line: build/X86/gem5.opt --debug-flags=MinorCPU -d result2/ configs/example/fs.py --cpu-type=minor --num-cpus=2 --kernel=/home/amirali/gem5/binaries/x86_64-vmlinux-2.6.32-smp --disk-image=/home/amirali/gem5/disks/linux_x86_16GB_2 --caches --ruby* *Global frequency set at 1000000000000 ticks per second* *warn: DRAM device capacity (8192 Mbytes) does not match the address range assigned (512 Mbytes)* *info: kernel located at: /home/amirali/gem5/binaries/x86_64-vmlinux-2.6.32-smp* *Listening for com_1 connection on port 3456* * 0: rtc: Real-time clock set to Sun Jan 1 00:00:00 2012* *0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000* *0: system.remote_gdb.listener: listening for remote gdb #1 on port 7001* *warn: Reading current count from inactive timer.* * 0: system.cpu0: ActivateContext thread: 0 0: system.cpu1: SuspendContext 0* ***** REAL SIMULATION ***** * 0: system.cpu0: MinorCPU startup* * 0: system.cpu0: ActivateContext thread: 0 0: system.cpu1: MinorCPU startup* * 0: system.cpu1: ActivateContext thread: 0 0: system.cpu1: ActivateContext thread: 0info: Entering event queue @ 0.
