Hi, is there any lock or something else I can use in order to achieve mutual exclusive in M5? For example, I want to implement a piece of code in the CPU model, such as in the postExecute() function. There are 4 cpu in my simulation, so every cpu will execution this extra code without any order guarantee. How can I make them mutual exclusive? Should I implement a lock by myself or is there anything I can use in M5. Thank you very much!
