Constructor & Destructor Documentation

◆ CacheCmdStats()

gem5::BaseCache::CacheCmdStats::CacheCmdStats	(	BaseCache &	c,
		const std::string &	name
	)

Definition at line 1949 of file base.cc.

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.
