hello all,
I've created my PauseThreadEvent class (see below) which will supposedly
allow me to pause threads while waiting for the CountedExitEvent(which I
also copied and modified) counter to equate to zero. My question is how do I
insert a call to PauseThreadEvent::process() in the CountedExit event given
that I do not have a thread context variable in the CountedExitEvent
class(or is it somewhere there?), a quick solution I can think of is to add
a ThreadContext pointer to the threads and call my PauseThread everytime I
encounter a CountedExitEvent. Is this a possible solution, in a scale of
1-5(5 being highest) my understanding of the M5 C++ internals is on level 1
so I guess I pretty much need help on anyone who can shine a light on my
issue.
another question: what file will I modify so that Scons will know that I
want my pause_thread_event.hh/cc to be compiled in M5?
Thanks in advance.
