// FUNCTION NAME: NvAPI_Initialize
//
//! This function initializes the NvAPI library (if not already initialized) but always increments the ref-counter.
//! This must be called before calling other NvAPI_ functions.
//! Note: It is now mandatory to call NvAPI_Initialize before calling any other NvAPI.

// FUNCTION NAME: NvAPI_Unload
//
//! DESCRIPTION: Decrements the ref-counter and when it reaches ZERO, unloads NVAPI library.
//! This must be called in pairs with NvAPI_Initialize.
//!
//! SUPPORTED OS: Windows 7 and higher
//!
//!
//! If the client wants unload functionality, it is recommended to always call NvAPI_Initialize and NvAPI_Unload in pairs.
//!
//! Unloading NvAPI library is not supported when the library is in a resource locked state.
//! Some functions in the NvAPI library initiates an operation or allocates certain resources
//! and there are corresponding functions available, to complete the operation or free the
//! allocated resources. All such function pairs are designed to prevent unloading NvAPI library.
//!
//! For example, if NvAPI_Unload is called after NvAPI_XXX which locks a resource, it fails with
//! NVAPI_ERROR. Developers need to call the corresponding NvAPI_YYY to unlock the resources,
//! before calling NvAPI_Unload again.
//!
//! \return This API can return any of the error codes enumerated in #NvAPI_Status. If there are return error codes with
//! specific meaning for this API, they are listed below.

//! This function can accept set of flags to request cached, uncached, sli and lid to get the connected devices.
//! Default value for flags will be cached .
//!
//! HOW TO USE: 1) for each PhysicalGpu, make a call to get the number of connected displayId's
//! using NvAPI_GPU_GetConnectedDisplayIds by passing the pDisplayIds as NULL
//! On call success:
//!
//! 2) If pDisplayIdCount is greater than 0, allocate memory based on pDisplayIdCount. Then make a call NvAPI_GPU_GetConnectedDisplayIds to populate DisplayIds.

// FUNCTION NAME: NvAPI_GPU_GetAllDisplayIds
//
//! DESCRIPTION: This API returns display IDs for all possible outputs on the GPU.
//! For DPMST connector, it will return display IDs for all the video sinks in the topology. \n
//! HOW TO USE: 1. The first call should be made to get the all display ID count. To get the display ID count, send in \n
//! a) hPhysicalGpu - a valid GPU handle(enumerated using NvAPI_EnumPhysicalGPUs()) as input, \n
//! b) pDisplayIds - NULL, as we just want to get the display ID count. \n
//! c) pDisplayIdCount - a valid pointer to NvU32, whose value is set to ZERO. \n
//! If all parameters are correct and this call is successful, this call will return the display ID's count. \n
//! 2. To get the display ID array, make the second call to NvAPI_GPU_GetAllDisplayIds() with \n
//! a) hPhysicalGpu - should be same value which was sent in first call, \n
//! b) pDisplayIds - pointer to the display ID array allocated by caller based on display ID count, \n
//! eg. malloc(sizeof(NV_GPU_DISPLAYIDS) * pDisplayIdCount). \n
//! c) pDisplayIdCount - a valid pointer to NvU32. This indicates for how many display IDs \n
//! the memory is allocated(pDisplayIds) by the caller. \n
//! If all parameters are correct and this call is successful, this call will return the display ID array and actual
//! display ID count (which was obtained in the first call to NvAPI_GPU_GetAllDisplayIds). If the input display ID count is
//! less than the actual display ID count, it will overwrite the input and give the pDisplayIdCount as actual count and the
//! API will return NVAPI_INSUFFICIENT_BUFFER.
//!
//! SUPPORTED OS: Windows 7 and higher
//!
//!
//! \param [in] hPhysicalGpu GPU selection.
//! \param [in,out] DisplayIds Pointer to an array of NV_GPU_DISPLAYIDS structures, each entry represents one displayID

// FUNCTION NAME: NvAPI_Mosaic_GetSupportedTopoInfo

//! DESCRIPTION: This API returns information on the topologies and display resolutions

//!
//! NOTE: Not all topologies returned can be set immediately.
//! See 'OUT' Notes below.
//!
//! Once you get the list of supported topologies, you can call
//! NvAPI_Mosaic_GetTopoGroup() with one of the Mosaic topologies if you need
//! more information about it.
//!
//! <b>'IN' Notes:</b> pSupportedTopoInfo->version must be set before calling this function.
//! If the specified version is not supported by this implementation,
//! an error will be returned (NVAPI_INCOMPATIBLE_STRUCT_VERSION).
//!
//! <b>'OUT' Notes:</b> Some of the topologies returned might not be valid for one reason or
//! another. It could be due to mismatched or missing displays. It
//! could also be because the required number of GPUs is not found.
//! At a high level, you can see if the topology is valid and can be enabled
//! by looking at the pSupportedTopoInfo->topoBriefs[xxx].isPossible flag.
//! If this is true, the topology can be enabled. If it
//! is false, you can find out why it cannot be enabled by getting the
//! details of the topology via NvAPI_Mosaic_GetTopoGroup(). From there,
//! look at the validityMask of the individual topologies. The bits can
//! be tested against the NV_MOSAIC_TOPO_VALIDITY_* bits.
//!
//! It is possible for this function to return NVAPI_OK with no topologies
//! listed in the return structure. If this is the case, it means that
//! the current hardware DOES support Mosaic, but with the given configuration
//! no valid topologies were found. This most likely means that SLI was not

//
//! \code
//! 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.
//!
//! \param [in] pDevice A pointer to D3D12 device.
//! \param [in] pDesc A pointer to a D3D12_RESOURCE_DESC structure that describes the resource.
//! \param [in] InitialState The initial state of the resource, as a bitwise-OR'd combination of D3D12_RESOURCE_STATES enumeration constants.
//! \param [in] pOptimizedClearValue Specifies a D3D12_CLEAR_VALUE that describes the default value for a clear color.
//! \param [in] riid The globally unique identifier (GUID) for the resource interface.
//! \param [out] ppvResource A pointer to a memory block that receives a pointer to the resource. Cannot be NULL.
//! \param [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

//! DESCRIPTION: Wrapper around ID3D12Device::CreateCommittedResource to allow creation of resources according to params provided.
//! HTEX resource is created when NV_D3D12_RESOURCE_FLAG_HTEX is set in the nvResourceFlags parameter.
//! NV_D3D12_RESOURCE_FLAG_CPUVISIBLE_VIDMEM gives driver hint to create the resource on cpu visible vidmem
//! only upload resources use this flag currently, others behave exactly as ID3D12Device::CreateCommittedResource
//! Otherwise the function behaves exactly same as regular ID3D12Device::CreateCommittedResource.
//! When NV_D3D12_RESOURCE_FLAG_HTEX is set, the texels are centered on integer coordinates and filtering
//! and LOD are calculated based on the size minus one, which then allows the edges to filter to the exact texels on the edge,
//! eliminating the border/edge filtering issue. Dimension of next mip level is CEIL(currentMipDimension/2), and size of smallest mip is 2x2.
//! Note that NV_D3D12_RESOURCE_FLAG_HTEX can't be used for shared resources.
//! Best practice: Query available space in cpu visible vidmem using NvAPI_D3D12_QueryCpuVisibleVidmem
//! before using NV_D3D12_RESOURCE_FLAG_CPUVISIBLE_VIDMEM
//!
//! \param [in] pDevice A pointer to D3D12 device.
//! \param [in] pHeapProperties A pointer to a D3D12_HEAP_PROPERTIES structure that provides properties for the resource's heap.
//! \param [in] HeapFlags Heap options, as a bitwise-OR'd combination of D3D12_HEAP_FLAGS enumeration constants.
//! \param [in] pDesc A pointer to a D3D12_RESOURCE_DESC structure that describes the resource.
//! \param [in] InitialState The initial state of the resource, as a bitwise-OR'd combination of D3D12_RESOURCE_STATES enumeration constants.
//! \param [in] pOptimizedClearValue Specifies a D3D12_CLEAR_VALUE that describes the default value for a clear color.
//! \param [in] pNVResourceParams A pointer to a structure containing additional NV specific resource creation information (see NV_D3D12_RESOURCE_FLAGS below for more info on flags)
//! \param [in] riid The globally unique identifier (GUID) for the resource interface.
//! \param [out] ppvResource A pointer to memory that receives the requested interface pointer to the created resource object.
//! ppvResource can be NULL, to enable capability testing. When ppvResource is NULL, no object will be created and pSupported
//! will be set to true when pResourceDesc is valid.

//! DESCRIPTION: Queries the driver for internally created allocations that accompany a swap chain buffer for present-related operations.
//! Surfaces returned by this interface must be destroied at the same time that the original swap chain buffer is destroyed.
//! In general this occurs prior to a ResizeBuffers call, or when the swap chain is released.
//! Note that this function only works in Landscape orientation due to Windows behavior, and attempts to utilize it with any type of display
//! rotation will result in failure.
//!
//! \param [inout] companionBufferCount The parameters for this function.
//!
//! \retval NVAPI_OK Call succeeded.
//! \retval NVAPI_ERROR Call failed.
//! \retval NVAPI_INVALID_ARGUMENT One or more arguments are invalid.
//! \retval NVAPI_INVALID_CALL System configuration does not support this interface (eg, display is rotated, mosaic not enabled, etc)

// FUNCTION NAME: NvAPI_D3D_SetSleepMode
//
//! DESCRIPTION: This function can be used to update sleep mode dynamically.
//! The settings are not dependent to each other, meaning low latency mode
//! can be enabled/disabled regardless of whether minimum interval is set or
//! not. The former is to intelligently lower latency without impacting frame
//! rate. The later is to limit frame rate (e.g. minimumIntervalUs = 10000
//! limits frame rate to 100 FPS). They work well separately and/or together.
//! Note that minimumIntervalUs usage is not limited to lowering latency, so
//! feel free to use it to limit frame rate for menu, cut scenes, etc.
//! Note that low latency mode can be enabled, and/or minimum interval can
//! be set, even without using NvAPI_D3D_Sleep(). However, without it, the
//! sleep to achieve these features would happen at a less optimal point,
//! resulting in higher overall latency.
//! The bLowLatencyBoost will request the GPU run at max clocks even in
//! scenarios where it is idle most of the frame and would normally try
//! to save power. This can decrease latency in CPU-limited scenarios.
//! While this function can be called as often as needed, it is not
//! necessary nor recommended to call this too frequently (e.g. every frame),
//! as the settings persist for the target device.

//! Rate setting, could be enabled in the control panel to benefit from this.
//! It is OK to start (or stop) using this function at any time. However,

//! DESCRIPTION: Set a latency marker to be tracked by the
//! NvAPI_D3D_GetLatency function. SIMULATION_START must be the first marker
//! sent in a frame, after the previous frame's Sleep call (if used).
//! INPUT_SAMPLE may be sent to record the moment user input was sampled and

//! RENDERSUBMIT_START should come before any Direct3D calls are made for
//! the given frame and RENDERSUBMIT_END should come before calling Present.
//! PRESENT_START and END should wrap the Present call to inform the driver
//! of a present block done by the OS before the driver receives the Present.
//! TRIGGER_FLASH tells the driver to render its flash indicator for latency
//! testing, typically driven by a mouse click.
//! The frameID can start at an abitrary moment in the application lifetime
//! but must strictly increment from that point forward for consistent results.
