Hello,

I am running a two CPU simulation in SE mode, and I would like to be able to have both of the programs reach a specific point before continuing (a barrier). Is there a built-in way for gem5 to do this? I was thinking perhaps suspending one CPU when the barrier is reached and then resuming it when the other CPU reaches the barrier.

If there isn't a way already in gem5, what would be the best way to add it? A new pseudo-instruction?

Thanks,
David Gloe
