Recently, I am trying to get the memory access trace from some benchmarks runing on GEM5. By reading the references http://www.m5sim.org/Main_Page, I got it done.
Below is an example:
1)scons build/X86_MESI_CMP_directory/gem5.opt PROTOCOL=MESI_CMP_directory RUBY=true
2) ./build/X86_MESI_CMP_directory/gem5.opt --debug-flags=RubyMemory --trace-file rubymemory130704 configs/example/ruby_fs.py --kernel=/home/starking/fullsystem/m5_system_2.0b3/binaries/x86_64-vmlinux-2.6.28.4-smp --disk-image=/home/starking/fullsystem/m5_system_2.0b3/disks/x86root-parsec.img --mem-size=1024MB --ruby
the point is --debug-flag , the choices to select could be displayed by the command:
./build/X86_MESI_CMP_directory/gem5.opt --debug-help
For just the memory access traces are what I want, so in the example above I chose --debug-flags=RubyMemory
