[Gems-users] hitcallback() question

[May Zhao <zhao0043@xxxxxxxxxxxxxxxxxxxxxxx>]

Hi ,

      I met a problem about hitcallback() in Sequencer.C. I found there 
are two functions will call hitcallback().
One is sequencer.writeCallback() from "hh_load_hit" event in 
MOSI_SMP_bcast-cache.sm.
Another is makeRequest() from SimicsProcessor.C. The first one execute 
cache coherence protocol through file
MOSI_SMP_bcast-cache.sm. However, the second flow also modify the data block in
L1Cache.
     My question is what difference between these two functions lead to 
hitcallback()? Why not all the requests will
be processed by MOSI_SMP_bcast-cache.sm? Why some requests come from 
SimicsProcessor.C to
perform hitcallback()? I found the makeRequest() from SimicsProcessor.C may 
cause the data inconsistency.
     Thank you very much for any help.

Regards,
May
