A.1.4. Treat cache invalidate operation as clean and invalidate

Rating: 1.

With the parameter vmsa.cache_treat_invalidate_as_clean set as true, a cache invalidate operation cleans any dirty lines before they are invalidated.


It is never appropriate to rely on incoherence effects of cached memory, because a cached view can be cleaned or evicted at any time.
