D3D12_SAMPLER_FEEDBACK_TIER enumeration (d3d12.h)

Defines constants that specify sampler feedback support.

Syntax

typedef enum D3D12_SAMPLER_FEEDBACK_TIER {
 D3D12_SAMPLER_FEEDBACK_TIER_NOT_SUPPORTED = 0,
 D3D12_SAMPLER_FEEDBACK_TIER_0_9 = 90,
 D3D12_SAMPLER_FEEDBACK_TIER_1_0 = 100
} ;

Constants

 
D3D12_SAMPLER_FEEDBACK_TIER_NOT_SUPPORTED
Value: 0
Specifies that sampler feedback is not supported. Attempts at calling sampler feedback APIs represent an error.
D3D12_SAMPLER_FEEDBACK_TIER_0_9
Value: 90
Specifies that sampler feedback is supported to tier 0.9. This indicates the following:

Sampler feedback is supported for samplers with these texture addressing modes:
* D3D12_TEXTURE_ADDRESS_MODE_WRAP
* D3D12_TEXTURE_ADDRESS_MODE_CLAMP

The Texture2D shader resource view passed in to feedback-writing HLSL methods has these restrictions:
* The MostDetailedMip field must be 0.
* The MipLevels count must span the full mip count of the resource.
* The PlaneSlice field must be 0.
* The ResourceMinLODClamp field must be 0.

The Texture2DArray shader resource view passed in to feedback-writing HLSL methods has these restrictions:
* All the limitations as in Texture2D above, and
* The FirstArraySlice field must be 0.
* The ArraySize field must span the full array element count of the resource.
D3D12_SAMPLER_FEEDBACK_TIER_1_0
Value: 100
Specifies sample feedback is supported to tier 1.0. This indicates that sampler feedback is supported for all texture addressing modes, and feedback-writing methods are supported irrespective of the passed-in shader resource view.
