Dear all I'm sorry to bother you. I read tutorials and find special opcodes in M5 is very useful. I want to insert a new operation into the source codejust for notifying each CPU how many times this operation does. 1. is that practical in gem5 ? 2. if it's possible, how to do it ?
Yes, it is possible to insert instructions in to the source code that are not part of the ISA definition. You might want to take a look at this page -- http://gem5.org/M5ops. It seems old, but would get you started.
Then, take a look at the files in util/m5, opcodes for some of the common operations have been defined. You can insert calls to functions defined util/m5/m5op.h, and then compile your application with the *.S file appropriate for your architecture.
