[gem5-users] Re: Pseudo Instruction - m5_reset_stats() - Body Modification
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.

[gem5-users] Re: Porting a configuration file from gem5 v20 to gem5 v21
Hi Giacomo, Indeed, I was able to use ArmMMU.connectWalkerPorts method and run the config file in fs mode. However, I a, still struggling with the segmentation fault in se mode. Does it make any sense to have a config file working in fs mode but failing in se? (notice that it is running in both fs and se mode in v20.0.0.)
