D3D12_DRED_PAGE_FAULT_OUTPUT structure (d3d12.h)

  • Article

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

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

A 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

A pointer to a constant D3D12_DRED_ALLOCATION_NODE 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

A pointer to a constant D3D12_DRED_ALLOCATION_NODE 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.
