Hi guys, I merely wanted to point out that gem5 already has extensive support for checkpoint and restore. Also, if all you want it to simulate for N ticks, then pause, do something, then continue, you can easily do this from python.
The other thread is on how to bridge Ethernet from a host into gem5. There I honestly do not see how a pause facility in the simulator will help you as it is already many 100-1000x slower than the host. Pausing it will only make it even slower. Am I missing something?

Can you give me some idea how to move forward?

I think there are plenty people out there that would be interested, and also have ideas and be able to help. If you don’t mind sharing it with the user list I’d suggest to reply not only to me, but also to gem5-users.

This would mean, that I should be able to pause/resume gem5 and also modify the gem5 schedule to run additional instructions/events provided by the observer. Thanks in advanced.

I don’t really understand what “adding my own events” really accomplishes, so perhaps you can shed some light on what it is you are trying to do.

The only way that I could found was to modify the gem5 simulation schedule myself, but I am still not able to do it and its very complicated way. Could you please share you progress/ideas?
