DXGK_BUILDPAGINGBUFFER_NOTIFYRESIDENCY describes a residency allocation change operation.
The kernel mode driver handle returned from DxgkDdiCreateAllocation.
The physical address of the allocation. The physical address (0, 0) is invalid and is used when the allocation is being evicted.
Set to 0 when the allocation is evicted and set to 1 when the allocation is committed.
This member is not used and should be set to zero.
The paging operations is issued only for allocations, for which the kernel mode driver sets the DXGK_ALLOCATIONINFOFLAGS::ExplicitResidencyNotification and AccessedPhysically flags.
The operation is issued after FillVirtual or TransferVirtual operations when the allocation is committed to a memory segment (Resident == 1). Note that the previous paging operations might not yet be finished by graphics processing unit (GPU).
The operation is issued before TransferVirtual operation when the allocation is evicted (Resident == 0) from a memory segment.
Note that the NotifyResidency operation will be issued only once during allocation eviction/commitment, while there might be several TransferVirtual/FillVirtual operations for a single allocation.
