  • Article

Creates a LearningModelDevice that will run inference on the user-specified ID3D12CommandQueue.

HRESULT CreateFromD3D12CommandQueue(
    ID3D12CommandQueue * value,
    [out] IUnknown ** result);

Parameters

Name Type Description
value ID3D12CommandQueue* The ID3D12CommandQueue which the LearningModelDevice will be run against.
result IUnknown** The LearningModelDevice to be created.

Returns

HRESULT The result of the operation.

Examples

 // 1. create the d3d device.
com_ptr<ID3D12Device> pD3D12Device = nullptr;
CHECK_HRESULT(D3D12CreateDevice(
    nullptr,
    D3D_FEATURE_LEVEL::D3D_FEATURE_LEVEL_11_0,
    __uuidof(ID3D12Device),
    reinterpret_cast<void**>(&pD3D12Device)));

// 2. create the command queue.
com_ptr<ID3D12CommandQueue> dxQueue = nullptr;
D3D12_COMMAND_QUEUE_DESC commandQueueDesc = {};
commandQueueDesc.Type = D3D12_COMMAND_LIST_TYPE_DIRECT;
CHECK_HRESULT(pD3D12Device->CreateCommandQueue(
    &commandQueueDesc,
    __uuidof(ID3D12CommandQueue),
    reinterpret_cast<void**>(&dxQueue)));
com_ptr<ILearningModelDeviceFactoryNative> devicefactory =
    get_activation_factory<LearningModelDevice, ILearningModelDeviceFactoryNative>();
com_ptr<::IUnknown> spUnk;
CHECK_HRESULT(devicefactory->CreateFromD3D12CommandQueue(dxQueue.get(), spUnk.put()));
