Re: [gem5-users] Pass address bounds of an array from application to gem5

Hi Armand, You can definitely do this in gem5! We have what we call m5ops or "magic instructions" that allow for these kinds of "hypercalls" from the simulated system into the simulator. The documentation has a little information about this (http://www.gem5.org/documentation/general_docs/m5ops/).

Re: [gem5-users] Cannot restoring from fs HPI checkpoint

It probably happens that when you try to restore (unserialize) the checkpoint, The BaseCPU::unserialize method in src/cpu/base.c is trying to restore the _pid field, but id doesn't find it in the checkpoint. If you take a look at the checkpoint you will see that under cpu0 it is probably
