[Gems-users] Zero L2 cache stats

["Binh Q. Pham" <phambinh1983@xxxxxxxxx>]

Hi,
I am using MESI_SCMP_bankdirectory protocol in my project, and after 
running a simulation, L2 cache doesn't have any misses:
L2_cache cache stats:
  L2_cache_total_misses: 0
  L2_cache_total_demand_misses: 0
  L2_cache_total_prefetches: 0
  L2_cache_total_sw_prefetches: 0
  L2_cache_total_hw_prefetches: 0
  L2_cache_misses_per_transaction: 0
  L2_cache_misses_per_instruction: 0
  L2_cache_instructions_per_misses: NaN

  L2_cache_request_size: [binsize: log2 max: 0 count: 0 average: NaN 
|standard d
eviation: NaN | 0 ]
Tracing back, I see this is because the function addSecondaryStatSample 
is called in profile_L2Cache_miss; but this profile_L2Cache_miss is 
commented out in MESI_SCMP_bankdirectory-L2cache.sm.
Next, if I remove the comment, I got the following error during compile:

../protocols/MESI_SCMP_bankdirectory-L2cache.sm:686: Error: Unrecognized 
function name: 'convertToGenericType'
make[1]: *** [generated/MESI_SCMP_bankdirectory/generated] Error 1

For some reason, the function convertToGenericType is auto-generated in 
some other protocol, e.g. MOSI_SMP_bcast; but not for 
MESI_SCMP_bankdirectory.
1. I would like to know why this is the case?
2. Also why is profile_L2Cache_miss commented out in the sm file? If 
this indeed should be left out, what should I do to get the L2 cache stats?
Thank you for your time and help,
