This structure contains the cache information and is used with the IOCTL_KLIB_GETCACHE_INFO IOCTL.

typedef struct _CacheInfo {  DWORD dwL1Flags;  DWORD dwL1ICacheSize;  DWORD dwL1ICacheLineSize;  DWORD dwL1ICacheNumWays;  DWORD dwL1DCacheSize;  DWORD dwL1DCacheLineSize;  DWORD dwL1DCacheNumWays;  DWORD dwL2Flags;  DWORD dwL2ICacheSize;  DWORD dwL2ICacheLineSize;  DWORD dwL2ICacheNumWays;  DWORD dwL2DCacheSize;  DWORD dwL2DCacheLineSize;  DWORD dwL2DCacheNumWays;} CacheInfo, *PCacheInfo;

Members

  • dwL1Flags
    Flags for the level 1 (L1) cache. The following table shows the valid flags for this member.

    Flag Description
    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.
    CF_COHERENT Specifies that no cache flush operations are necessary.

  • 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, 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. For direct-mapped, use 1.

  • dwL2Flags
    Flags for the level 2 (L2) cache.

    The following flags are valid for this member.

    Flag Description
    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.
    CF_COHERENT Specifies that no cache flush operations are necessary.

  • 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, 1 for direct-mapped.

  • dwL2DCacheSize
    Total size of the L2 data cache, in bytes. A size of 0 (zero) means 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. For direct-mapped, use 1.
