PFND3D12DDI_CHECKRESOURCEALLOCATIONINFO_0075 callback function (d3d12umddi.h)

  • Artikel

The PFND3D12DDI_CHECKRESOURCEALLOCATIONINFO_0075 callback function supports checking resource allocation information.

Syntax

PFND3D12DDI_CHECKRESOURCEALLOCATIONINFO_0075 Pfnd3d12ddiCheckresourceallocationinfo0075;

void Pfnd3d12ddiCheckresourceallocationinfo0075(
        D3D12DDI_HDEVICE unnamedParam1,
  [in]  const D3D12DDIARG_CREATERESOURCE_0075 *unnamedParam2,
        D3D12DDI_RESOURCE_OPTIMIZATION_FLAGS unnamedParam3,
        UINT32 AlignmentRestriction,
        UINT VisibleNodeMask,
  [out] D3D12DDI_RESOURCE_ALLOCATION_INFO_0022 *unnamedParam6
)
{...}

Parameters

unnamedParam1

A handle to the display device (graphics context).

[in] unnamedParam2

Pointer to a D3D12DDIARG_CREATERESOURCE_0075 structure.

unnamedParam3

Resource optimization flags.

AlignmentRestriction

A resource alignment restriction value.

VisibleNodeMask

For a multi-adapter operation, this value indicates the set of nodes where the resource is visible. Passing zero is equivalent to passing one, in order to simplify the usage of single-GPU adapters.

[out] unnamedParam6

Pointer to a D3D12DDI_RESOURCE_ALLOCATION_INFO_0022 structure containing information for resource allocation.

Return value

None

Remarks

This callback function is part of a two step process of resource creation. This function determines the sizes and alignments of the resource data, additional data header, and additional data is determined, along with the texture layout. When the resource description is passed into this function, the layout of the resource description may be set to _UNDEFINED. This allows the driver to choose any texture layout. When the layout of the resource description is STANDARD_SWIZZLE or ROW_MAJOR, the driver must return out the corresponding value as its choice.

This callback function is accessed by using the D3D12DDI_DEVICE_FUNCS_CORE_0075 structure.

Requirements

Requirement Value
Minimum supported client Windows 10, version 2004
Target Platform Windows
Header d3d12umddi.h (include D3d12umddi.h)
