Member Function Documentation

regStatsFromParent()

void gem5::BaseCache::CacheCmdStats::regStatsFromParent

(

)

Callback to register stats from parent CacheStats::regStats().

We can't use the normal flow since there is is no guaranteed order and CacheStats::regStats() needs to rely on these stats being initialised.
