Re: [Gems-users] How to add additional member to each L2 cache entry

[Polina Dudnik <pdudnik@xxxxxxxxx>]

Liz,

So, like I said in my previous email, the requestor id (L1 id) is already known at L2. If you want to see it in CacheMemory, here's what you can do: add whatever function to CacheMemory that you would like to call to process id's (say void monitorId(int id). In the -L2cache.sm find CacheMemory, add a declaration of that function. Now you can call that function from actions in -L2cache.sm. So, say your L2 is processing a request from L1 (look for L1RequestIntraChipL2Network_in), then if you wish you can call your function and pass the L1 id to it like so: L2cacheMemory.monitorId(in_msg.RequestorMachId), I think that would work.

Thanks for your reply,Polina

How can we add this MachineID in the request msg to each L2 cache entry.Where I need to make the assignment?I need this information in CacheMemory.h.Also,If we have some private area within the shared L2 cache for each core and need to check for a hit in both the shared area and the private area,where I need to make the changes in computing the set and the tag.Is it n CacheMemory.h or somewhere else too?

Thanks in Advance
Liz
