Enumeration Type Documentation

Bus message IDs.

Enumerator
ProcRead	Read access on a cache line.
ProcWrite	Write access on a cache line.
BusRead	Bus read message issued by a cache.
BusReadX	Bus read-exclusive message issued by a cache.
BusUpdate	Bus update message issued by a cache.
BusUpgrade	Bus write message issued by a cache.
BusWrite	Bus upgrade message issued by a cache.
N_MESSAGES	Number of bus messages.

Cache line state.

Enumerator
Unallocated	Alias for invalid, used in protocols that don't invalidate.
I	Invalid.
D	Dirty exclusive.
E	Clean exclusive.
M	Modified exclusive.
V	Valid exclusive.
O	Owned.
S	Shared.
Sc	Shared clean.
Sm	Shared modified.

Cache runtime statistic IDs.

Enumerator
ReadMiss	Read miss on a cache line.
WriteMiss	Write miss on a cache line.
LineFlush	Cache line data broadcasted across memory bus.
LineFetch	Cache line data retrieved from main memory.
CacheToCache	Transfer between two caches.
WriteBack	Cache line data written to main memory.
WriteMemory	Direct write from CPU to main memory.
Eviction	Cache line evicted by the replacement policy.
Exclusion	Cache line changes from shared (O, S, Sc, Sm) to singular (D, E, M, V)
Intervention	Cache line changes from singular (D, E, M, V) to shared (O, S, Sc, Sm)
Invalidation	Cache line state set to invalid (I)
N_STATISTICS	The number of statistics a cache keeps track of; not a statistic.
