How to use PIMProcess

[m1chaelyeung]

I see PIMProcess is declared in pseudo_inst.cc, so how can I use this function in my program. Should I run my program in fs mode?

I have a similar question that there are two functions called "PIMProcess" and "HostProcess" in pseudo_inst.cc. Do you know how can I use them?

I have read the source code of PIMProcess and HostProcess. I only add PIMProcess into my own cpp code and compile it as kernel. Then I set up the parameters of my system and run gem5. But I got a segmentation fault during the runtime and I haven't solved it.
