The DXGK_NATIVE_FENCE_LOG_HEADER structure contains the header information for the native fence log buffer.
Syntax
typedef struct _DXGK_NATIVE_FENCE_LOG_HEADER {
union {
struct {
UINT32 FirstFreeEntryIndex;
UINT32 WraparoundCount;
};
ULARGE_INTEGER AtomicWraparoundAndEntryIndex;
};
DXGK_NATIVE_FENCE_LOG_TYPE Type;
UINT64 NumberOfEntries;
UINT64 Reserved[2];
} DXGK_NATIVE_FENCE_LOG_HEADER;
Members
FirstFreeEntryIndex
Index of the first free entry in the log. FirstFreeEntryIndex is the same value as the LowPart of AtomicWraparoundAndEntryIndex.
WraparoundCount
The number of times the log entries have wrapped around. Same value as the HighPart of AtomicWraparoundAndEntryIndex.
AtomicWraparoundAndEntryIndex
A 64-bit integer that contains the FirstFreeEntryIndex in the LowPart and the WraparoundCount in the HighPart.
Type
A DXGK_NATIVE_FENCE_LOG_TYPE enumeration that specifies the type of the native fence log entries.
NumberOfEntries
Number of DXGK_NATIVE_FENCE_LOG_ENTRY structures in the Entries array of the native fence log buffer.
Reserved[2]
Reserved for system use.
