Members
dwL1Flags
Flags for the level 1 (L1) cache.The following table shows the valid flags for this member.
Flag Description CF_COHERENT
Specifies that no cache flush operations are necessary.
CF_UNIFIED
Specifies that the instruction (I) and data (D) caches are unified.
CF_WRITETHROUGH
Specifies that the cache is in write-through mode. If this flag is not set, the cache is in write-back mode.
- dwL1ICacheSize
Total size of the L1 instruction cache, in bytes.
- dwL1ICacheLineSize
Line size of the L1 instruction cache, in bytes.
- dwL1ICacheNumWays
Specifies the number of ways. Set to 1 for direct-mapped.
- dwL1DCacheSize
Total size of the L1 data cache, in bytes.
- dwL1DCacheLineSize
Line size of the L1 data cache, in bytes.
- dwL1DCacheNumWays
Specifies the different types of cache organization. Set to 1 for direct-mapped.
dwL2Flags
Flags for the level 2 (L2) cache.The following table shows the valid flags for this member.
Flag Description CF_COHERENT
Specifies that no cache flush operations are necessary.
CF_UNIFIED
Specifies that the instruction (I) and data (D) caches are unified.
CF_WRITETHROUGH
Specifies that the cache is in write-through mode. If this flag is not set, the cache is in write-back mode.
- dwL2ICacheSize
Total size of the L2 instruction cache, in bytes. A size of 0 (zero) means that there is no L2 instruction cache.
- dwL2ICacheLineSize
Line size of the L2 instruction cache, in bytes.
- dwL2ICacheNumWays
Specifies the number of ways. Set to 1 for direct-mapped.
- dwL2DCacheSize
Total size of the L2 data cache, in bytes. Zero indicates that there is no L2 data cache.
- dwL2DCacheLineSize
Line size of the L2 data cache, in bytes.
- dwL2DCacheNumWays
Specifies the different types of cache organization. Set to 1 for direct-mapped.
