Hi all, I've checked the scripts under configs/example and configs/common. However, I didn't find the option or related functions to dump the statistics every N cycles. I do try the "checkpoints" option, but the output is not the same as in "m5out/stats.txt".
Could anybody let me know how I can dump the statistics for every N cycles? For example, any option I can try or the part of code I need to change? Thanks a lot.
