D3D11_TILED_RESOURCES_TIER enumeration (d3d11.h)

  • Article

Indicates the tier level at which tiled resources are supported.

Syntax

typedef enum D3D11_TILED_RESOURCES_TIER {
  D3D11_TILED_RESOURCES_NOT_SUPPORTED = 0,
  D3D11_TILED_RESOURCES_TIER_1 = 1,
  D3D11_TILED_RESOURCES_TIER_2 = 2,
  D3D11_TILED_RESOURCES_TIER_3 = 3
} ;

Constants

 
D3D11_TILED_RESOURCES_NOT_SUPPORTED
Value: 0
Tiled resources are not supported.
D3D11_TILED_RESOURCES_TIER_1
Value: 1
Tier_1 tiled resources are supported.

The device supports calls to CreateTexture2D and so on with the D3D11_RESOURCE_MISC_TILED flag.


The device supports calls to CreateBuffer with the D3D11_RESOURCE_MISC_TILE_POOL flag.


If you access tiles (read or write) that are NULL-mapped, you get undefined behavior, which includes device-removed. Apps can map all tiles to a single "default" tile to avoid this condition.
D3D11_TILED_RESOURCES_TIER_2
Value: 2
Tier_2 tiled resources are supported.


Superset of Tier_1 functionality, which includes this additional support:



  • On Tier_1, if the size of a texture mipmap level is an integer multiple of the standard tile shape for its format, it is guaranteed to be nonpacked. On Tier_2, this guarantee is expanded to include mipmap levels whose size is at least one standard tile shape.
    For more info, see D3D11_PACKED_MIP_DESC.

  • Shader instructions are available for clamping level-of-detail (LOD) and for obtaining status about the shader operation. For info about one of these shader instructions, see Sample(S,float,int,float,uint).

  • Reading from NULL-mapped tiles treat that sampled value as zero. Writes to NULL-mapped tiles are discarded.
D3D11_TILED_RESOURCES_TIER_3
Value: 3
Tier_3 tiled resources are supported.


Superset of Tier_2 functionality, Tier 3 is essentially Tier 2 but with the additional support of Texture3D for Tiled Resources.
