Hi Marti,
I would think that you could use a boolean variable that you defined
in the CacheEntry/DirEntry Structure of the L2, and when set to false,
don't do the desired action.
For example:
inport(my_port, RequestMsg, latency="") {
peek(my_port, RequestMsg) {
bool flag := getEntryFlag(cache_entry, address);
if(flag) {
trigger(Event: ........);
}
// else do nothing
o
}
}
The getEntryFlag Function could be something you define similar to the
isLocalOwnerValid Function.
But in this case, the port is still scheduled and woken up every
cycle, but you just don't execute anything.
If you truly don't want the port to be scheduled for wakeup, it is a
little more tricky. Essentially each in_port inherits from the
Consumer Class (/ruby/common/Consumer.hh)
What you can do, is check to see if the L1RequestToL2 in_port
(consumer) is scheduled for some said cycle using
the bool alreadySchedule(Time) function, and if not, then schedule
your port (consumer) to wake up.
Does that make sense?
