I see. Thanks for the clarification. Will see if DPRINTF works, otherwise will write to a file, which should be ok as I am calling m5_stat_reset only once.

I would suggest using DPRINTF instead of cout. It's possible that some print statements aren't being flushed.

Hi Jason, I have added a std::cout statement to the resetstats()'s body and I am calling m5_reset_stats from my GPU benchmarks. The GPU kernels are launched right after reset is called. I pipe the output of simulations to a file. But, strangely enough some outputs show the std::cout statements while others don't. What could be the reason ?

Hi Sampad, Here is where m5_reset_stats is implemented in the simulator: https://gem5.googlesource.com/public/gem5/+/refs/heads/stable/src/sim/pseudo_inst.cc#303 There are a large number of steps between when the guest code calls m5_reset_stats and when the above function executes, but this should help you start hacking :).
