Hi, I am copying the instructions from my answer to another gem5 question to increase your disk image size: https://www.mail-archive.com/gem5-users@gem5.org/msg16495.html fsck and its variations can be used on a partition, not on an entire image file/disk. Since you are using an image file, you

Hi, I am sure there are much better ways to do this but so far there are not any other suggestions. One solution could be creating an event and scheduling it to monitor the number of misses. When the number reaches N, exitSimLoop exits the simulation with a cause, such as "Encountered N

Hi, You need to decode the trace file using gem5/util/decode_packet_trace.py. This python file dumps the traces to ASCII. More information on the fields can be found here: https://www.gem5.org/documentation/general_docs/cpu_models/TraceCPU Serhat From:

Hi, Yes, you can trace the packets by using CommMonitor. You will need to add the monitor between cache and cpu (gem5/src/cpu/BaseCPU.py). Take a look at: gem5/src/mem/CommMonitor.py and http://old.gem5.org/General_Memory_System.html (there is a traffic analysis subsection which could be
