# D3D12_DRED_PAGE_FAULT_OUTPUT

> Describes allocation data related to a GPU page fault on a given virtual address (VA).

Describes allocation data related to a GPU page fault on a given virtual address (VA). Contains the VA of a GPU page fault, together with a list of matching allocation nodes for active objects, and a list of allocation nodes for recently deleted objects.

## Syntax

```cpp theme={null}
typedef struct D3D12_DRED_PAGE_FAULT_OUTPUT
{
    D3D12_GPU_VIRTUAL_ADDRESS PageFaultVA;
    const D3D12_DRED_ALLOCATION_NODE  pHeadExistingAllocationNode;
    const D3D12_DRED_ALLOCATION_NODE  pHeadRecentFreedAllocationNode;
} D3D12_DRED_PAGE_FAULT_OUTPUT
```

### Members

*PageFaultVA*\
Type: D3D12\_GPU\_VIRTUAL\_ADDRESS

A [D3D12\_GPU\_VIRTUAL\_ADDRESS](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/d3d12_gpu_virtual_address) containing the GPU virtual address (VA) of the faulting operation if device removal was due to a GPU page fault.

*pHeadExistingAllocationNode*\
Type: const D3D12\_DRED\_ALLOCATION\_NODE \*

A pointer to a constant [D3D12\_DRED\_ALLOCATION\_NODE](/reference/graphics/d3d12/structs/d3d12_dred_allocation_node_public) object representing the head of a linked list of allocation nodes for active allocated runtime objects with virtual address (VA) ranges that match the faulting VA (`PageFaultVA`). Has a value of `nullptr` if the list is empty.

*pHeadRecentFreedAllocationNode*\
Type: const D3D12\_DRED\_ALLOCATION\_NODE \*

A pointer to a constant [D3D12\_DRED\_ALLOCATION\_NODE](/reference/graphics/d3d12/structs/d3d12_dred_allocation_node_public) object representing the head of a linked list of allocation nodes for recently freed runtime objects with virtual address (VA) ranges that match the faulting VA (`PageFaultVA`). Has a value of `nullptr` if the list is empty.

## Requirements

**Header:** d3d12\_xs.h or d3d12\_x.h\
**Library:** d3d12\_xs.lib or d3d12\_x.lib\
