[Gems-users] Issues with MSI_...L2-sim

[Muhammad Shoaib <shoaibbinalt@xxxxxxxx>]

Hi List,


I am trying to keep track of the number of times a address is referenced  in L2 cache.  For this I have added a "counter" entry in the Cache structure (in MSI_MOSI_CMP_dierctory_L2cache.sm) & its value gets incremented on each reference 

================================================================

L2cacheMemory[addr].counter:=L2cacheMemory[addr].counter+1;  // called in whenever a request comes either from private L1 or from other nodes
=================================================================

I also want to clear this counter value when a line gets deallocated, for this I reset the counter on the following action

==============================================================================

action(rr_deallocateL2CacheBlock, "\r", desc="Deallocate L2 cache block.  Sets the cache to not present, allowing a replacement in parallel with a fetch.") {
  
L2cacheMemory[address].counter:=0;
  
    L2cacheMemory.deallocate(address);
  }
==============================================================================


But the problem is the counter never gets cleared it is always incrementing, even though the line gets deallocated!!!


Any idea why this is happening or I am doing something wrong???
