CIM_AssociatedCacheMemory¶
Class reference¶
Subclass of CIM_AssociatedMemory
Indicates that the Memory provides Cache to the Dependent Logical Element.
Key properties¶
Local properties¶
uint16 WritePolicy
Defines whether this is write-back (value=2) or write-through (value=3) Cache, or whether this information “Varies with Address” (4) or is defined individually for each I/O (5). Also, “Other” (1) and “Unknown” (0) can be specified.
ValueMap Values 0 Unknown 1 Other 2 Write Back 3 Write Through 4 Varies with Address 5 Determination Per I/O
uint32 FlushTimer
Maximum amount of time, in seconds, dirty lines or buckets may remain in the Cache before they are flushed. A value of zero indicated that a cache flush is not controlled by a flushing timer.
uint16 CacheType
Defines whether this is for instruction caching (value=2), data caching (value=3) or both (value=4, “Unified”). Also, “Other” (1) and “Unknown” (0) can be defined.
ValueMap Values 0 Unknown 1 Other 2 Instruction 3 Data 4 Unified
uint32 LineSize
Size, in bytes, of a single cache bucket or line.
string OtherLevelDescription
A string describing the cache level when the Level value is 1, “Other”.
string OtherReplacementPolicyDescription
A string describing the Cache replacement policy when the ReplacementPolicy value is 1, “Other”.
uint16 ReadPolicy
Policy that shall be employed by the Cache for handling read requests. For example, “Read”, “Read-Ahead” or both can be specified using the values, 2, 3 or 4, respectively. If the read policy is determined individually (ie, for each request), then the value 5 (“Determination per I/O”) should be specified. “Other” (1) and “Unknown” (0) are also valid values.
ValueMap Values 0 Unknown 1 Other 2 Read 3 Read-Ahead 4 Read and Read-Ahead 5 Determination Per I/O
string OtherWritePolicyDescription
A string describing the Write Policy when the WritePolicy value is 1, “Other”.
uint16 ReplacementPolicy
An integer enumeration describing the algorithm to determine which cache lines or buckets should be re-used.
ValueMap Values 0 Unknown 1 Other 2 Unknown 3 Least Recently Used (LRU) 4 First In First Out (FIFO) 5 Last In First Out (LIFO) 6 Least Frequently Used (LFU) 7 Most Frequently Used (MFU) 8 Data Dependent Multiple Algorithms
uint16 Associativity
An integer enumeration defining the system cache associativity. For example, 5 indicates a fully associative cache.
ValueMap Values 0 Unknown 1 Other 2 Direct Mapped 3 2-way Set-Associative 4 4-way Set-Associative 5 Fully Associative 6 8-way Set-Associative 7 16-way Set-Associative 8 12-way Set Associative 9 24-way Set Associative 10 32-way Set Associative 11 48-way Set Associative 12 64-way Set Associative 13 20-way Set Associative
string OtherReadPolicyDescription
A string describing the read policy when the ReadPolicy value is 1, “Other”.
uint16 Level
Defines whether this is the Primary (value=3), Secondary (value=4) or Tertiary (value=5) Cache. Also, “Other” (1), “Unknown” (0) and “Not Applicable” (2) can be defined.
ValueMap Values 0 Unknown 1 Other 2 Not Applicable 3 Primary 4 Secondary 5 Tertiary
string OtherAssociativityDescription
A string describing the cache associativity when the Associativity value is 1, “Other”.
string OtherCacheTypeDescription
A string describing the Cache Type when the CacheType value is 1, “Other”.
