Hello, I have submitted a changeset to gem5 that will alter the way stats output at the end of the simulation. These changes unify stats with similar names from different CPUs, such as insts in the O3 CPU versus numInsts in the Simple CPU. It also moves some stats that are only located in specific CPUs into a more general Base CPU output if they could be beneficial to output for all CPUs, such as cpi and ipc from the Minor CPU. These general-purpose stats are moved into the BaseCPU object through stat group structs FetchCPUStats, ExecuteCPUStats, and CommitCPUStats. To view more specifics on these changes, and how they'll affect how you read stats from gem5, visit the Jira Issue <https://gem5.atlassian.net/browse/GEM5-1304> for these changes, which contains comparisons of these changes, as well as example mappings of old stat names to new ones.
Best, Melissa Jost
