	)

SUPPORTED OS: Windows 8 and higherSUPPORTED OS: Windows 8 and higherSUPPORTED OS: Windows 8 and higherSUPPORTED OS: Windows 8 and higherSUPPORTED OS: Windows 7 and higher DESCRIPTION: This function allows creating (aliasing) a non-MSAA Texture2D object using the same memory as the given multi-sampled texture (pInputTex). The surface created would be bloated in width and height but it will have SampleCount = 1 For 2X MSAA: OutTex.Width = InputTex.Width * 2, outTex.Height = InputTex.Height For 4X MSAA: OutTex.Width = InputTex.Width * 2, outTex.Height = InputTex.Height * 2 For 8X MSAA: OutTex.Width = InputTex.Width * 4, outTex.Height = InputTex.Height * 2 Only textures SampleQuality = 0 can be aliased as Non MSAA The app should ensure that original texture is released only after the aliased copy is released.

This function is free-threaded create compatible i.e. it can be called from a different thread than the one calling immediate device setstate functions.

Parameters

[in]	pDevice	current d3d device

	)

DESCRIPTION: This function tries to create a DirectX 11 device. If the call fails (if we are running on pre-DirectX 11 hardware), depending on the type of hardware it will try to create a DirectX 10.1 OR DirectX 10.0+ OR DirectX 10.0 device. The function call is the same as D3D11CreateDevice(), but with an extra argument (D3D_FEATURE_LEVEL supported by the device) that the function fills in. This argument can contain -1 (NVAPI_DEVICE_FEATURE_LEVEL_NULL), if the requested featureLevel is less than DirecX 10.0.

NOTE: When NvAPI_D3D11_CreateDevice is called with 10+ feature level we have an issue on few set of tesla hardware (G80/G84/G86/G92/G94/G96) which does not support all feature level 10+ functionality e.g. calling driver with mismatch between RenderTarget and Depth Buffer. App developers should take into consideration such limitation when using NVAPI on such tesla hardwares. SUPPORTED OS: Windows 7 and higher

SUPPORTED OS: Windows 7 and higher

DESCRIPTION: This function will convert a regular geometry shader into a fast GS variant if possible. It will not do any validation regarding the compatibility of the resulting fast GS with any Pixel shader. The validation has to be done by the application manually.

The parameters are identical to ID3D11Device::CreateGeometryShader() so please refer to its documentation for their usage.

If the shader is too complex or is not in adequate form to be converted to fast GS this function will simply fail. You should then call ID3D11Device::CreateGeometryShader() to create the regular geometry shader.

This function is free-threaded create compatible i.e. it can be called from a different thread than the one calling immediate device setstate functions.

Since: Release:

Parameters

[in]	pDevice	The device pointer
[in]	pShaderBytecode	A pointer to the compiled shader.
[in]	BytecodeLength	Size of the compiled geometry shader.
[in]	pClassLinkage	A pointer to a class linkage interface. Can be NULL.
[out]	ppGeometryShader	Address of a pointer to a ID3D11GeometryShader interface.

		__in const NvAPI_D3D11_CREATE_FASTGS_EXPLICIT_DESC *	pCreateFastGSArgs,
		__out ID3D11GeometryShader **	ppGeometryShader
	)

DESCRIPTION: This function will create a fast geometry shader written using an "explicit" coding style, rather than converting a standard GS. For the explicit coding style, the GS must be written with maxvertexcount(1), and must pass-through input vertex 0 to the output without modification.

Additional per-primitive outputs may also be computed and written to the single output vertex. If these outputs are read by the pixel shader, they must be declared with the "nointerpolation" attribute in the PS input signature; otherwise, visual corruption may occur. Also, unlike D3D API, there is no guarantee that pixel shader will get the default value of an attribute if that attribute is not written by the earlier shader stage in the pipeline.

The first four parameters are identical to ID3D11Device::CreateGeometryShader(), so please refer to its documentation for their usage.

This function is free-threaded create compatible i.e. it can be called from a different thread than the one calling immediate device setstate functions.

	)

DESCRIPTION: This function allows us to extend the creation of geometry shaders with extra bits of functionality.

The first parameters are identical to ID3D11Device::CreateGeometryShader() so please refer to its documentation for their usage.

The new parameter is UseViewportMask which is to tell the driver to create a shader that outputs a viewport mask instead when a viewport index is indicated. Outputting a viewport mask allows a single primitive to land on many different viewports as specified by the bits set in the mask, rather than to rely on a single number that tells it which unique viewport it would be drawn on. This can be used for example in conjunction with the setting of coordinates swizzling (see XXX_NVAPI function) to generates multiple adjacent views of the same primitive in a more efficient fashion (outputting the primitive only once).

This function is free-threaded create compatible i.e. it can be called from a different thread than the one calling immediate device setstate functions.

	)

Since: Release: 375

DESCRIPTION: Tiled resource is supported for Texture2D Array, however, but only when mip packing is not triggered. So any mip level cannot be smaller than a single tile size(64KB). This set of API is an extension of D3D12 support for tiled resource to allow a tiled texture2D array with mip packing. If any of API from this set is used, using all of them is highly recommended. It includes NvAPI_D3D12_CreateReservedResource, NvAPI_D3D12_CreateHeap, NvAPI_D3D12_ReservedResourceGetDesc, NvAPI_D3D12_UpdateTileMappings, NvAPI_D3D12_CopyTileMappings, NvAPI_D3D12_ResourceAliasingBarrier. Reminder: all API in this set other than NvAPI_D3D12_CreateReservedResource won't has D3D Debug Layer information.

NvAPI_D3D12_CreateReservedResource is an extension of ID3D12Device::CreateReservedResource. Use this function to create a tiled Texture2D array with mip packing. Runtime doesn't know the created resource is actually a tiled resource. Any other D3D12 API where runtime will check whether resource is tiled or not, has a corresponding NVAPI version and they should be used. Different from DX11 implementation, we highly recommend replace all ID3D12Device::CreateReservedResource with NvAPI_D3D12_CreateReservedResource, and use bTexture2DArrayMipPack to control which creation to use. Otherwise, NvAPI_D3D12_ResourceAliasingBarrier will fail if any resource is not created by NvAPI_D3D12_CreateReservedResource. DX11 implementation doesn't have this restriction and resource created by NVAPI and D3D API can be used together. pHeap is necessary when bTexture2DArrayMipPack is true. pHeap can be any heap and this API doens't change anything to it.

Parameters

[in]	pDevice	A pointer to D3D12 device.
[in]	pDesc	A pointer to a D3D12_RESOURCE_DESC structure that describes the resource.
[in]	InitialState	The initial state of the resource, as a bitwise-OR'd combination of D3D12_RESOURCE_STATES enumeration constants.
[in]	pOptimizedClearValue	Specifies a D3D12_CLEAR_VALUE that describes the default value for a clear color.
[in]	riid	The globally unique identifier (GUID) for the resource interface.
[out]	ppvResource	A pointer to a memory block that receives a pointer to the resource. Cannot be NULL.
[in]	bTexture2DArrayMipPack	Whether pDesc indicates it's a texture2D array resource with mip packing. TRUE: Use NVAPI to create. Will check pHeap to be not NULL. FALSE: Standard D3D12 API will be used, use DebugDevice to check any runtime ERROR. Won't check pHeap
[in]	pHeap	A pointer to ID3D12Heap. Cannot be NULL when bTexture2DArrayMipPack is true.

NVAPI_INTERFACE NvAPI_D3D12_SetNvShaderExtnSlotSpace	(	__in IUnknown *	pDev,
		__in NvU32	uavSlot,
		__in NvU32	uavSpace
	)

DESCRIPTION: This function is specifically created for ray tracing since we do not currently support PSOs with DXR. This function sets the device's fake UAV slot and space that is used by NVIDIA HLSL shader extensions globally. All state objects created by the driver after setting this slot would treat writes/reads to this UAV in a different way. Applications are expected to bind null UAV to this slot. The same slot is used for all shader stages. To disable shader extensions the app need to set this uav slot to 0xFFFFFFFF. To use NVIDIA HLSL extensions the application must include nvHLSLExtns.h in the hlsl shader code. See nvHLSLExtns.h for more details.

This function can be called from a different thread than the one calling immediate device setstate functions.

SUPPORTED OS: Windows 7 and higher

Parameters

[in]	pDev	The device for which to set the extension slot should be a ID3D12Device+ device
[in]	uavSlot	The UAV slot to use

DESCRIPTION: This function is specifically created for ray tracing shaders since we do not currently support PSOs with DXR. This function sets the device's fake UAV slot that is used by Nvidia HLSL shader extensions on local thread. All state objects created by the driver on the same thread that call this function after setting this slot would treat writes/reads to this UAV in a different way. Applications are expected to bind null UAV to this slot. The same slot is used for all shader stages for the device. To disable shader extensions the app may set this uav slot to 0xFFFFFFFF. To use Nvidia HLSL extensions the application must include nvHLSLExtns.h in the hlsl shader code. See nvHLSLExtns.h for more details.
