[Gems-users] DataBlk in CacheMsg?

[Hemayet Hossain <hossain@xxxxxxxxxxxxxxxx>]

Hi Everybody,
I have a dumb question. I would really appreciate if someone can clear 
the thing. I am assuming data are maintained in Cache.
Let us consider a Store comes from a processor but that for that L1 miss 
occurs. So L1 controller will issue a GETX and after getting the GETX 
response from L2 controller (i.e Data), L1 controller needs to update 
the specific bytes (for which Store was happened). But I am not clear 
about how the data from processor is coming to L1 controller. Is it 
through CacheMsg that was originally sent through Mandatory Queue? or 
any other way? Can you plz explain?
Thanks.
