基于UMD的DirectX 11纹理共享失败：OpenSharedResource返回E_INVALIDARG

我基于Microsoft Indirect Display Driver Sample开发用户模式驱动（UMD），希望与实时用户态进程共享D3D11纹理。但客户端进程尝试打开共享资源时，OpenSharedResource调用失败并返回E_INVALIDARG。

我已尝试以下操作：

• 确保UMD与客户端使用同一GPU适配器
• 确认句柄有效且有值
• 对比CreateSharedHandle+OpenSharedResource1与GetSharedHandle+OpenSharedResource的使用差异
• 设置desc.MiscFlags = D3D11_RESOURCE_MISC_SHARED | D3D11_RESOURCE_MISC_SHARED_NTHANDLE
• 将句柄转换为UINT64以适配64位架构
• 相同代码在两个常规进程间可正常运行

UMD端共享纹理代码 #

HANDLE hPipe = CreateNamedPipeW(
    L"\\\\.\\pipe\\MyD3DSharedHandlePipe",
    PIPE_ACCESS_OUTBOUND,    
    PIPE_TYPE_BYTE | PIPE_WAIT,
    PIPE_UNLIMITED_INSTANCES,
    512, 512, 0, nullptr
);

D3D11_TEXTURE2D_DESC desc = {};
//...
desc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
desc.SampleDesc.Count = 1;
desc.Usage = D3D11_USAGE_DEFAULT;
desc.BindFlags = D3D11_BIND_SHADER_RESOURCE | D3D11_BIND_RENDER_TARGET;
desc.MiscFlags = D3D11_RESOURCE_MISC_SHARED;

ComPtr<ID3D11Texture2D> _SharedTexture;
HRESULT hr = _Device->CreateTexture2D(&desc, nullptr, &_SharedTexture);

ComPtr<IDXGIResource> sharedResource;
_SharedTexture.As(&sharedResource);

HANDLE sharedHandle = nullptr;
hr = sharedResource->GetSharedHandle(&sharedHandle);
//Tried UINT64 as well.
BOOL written = WriteFile(hPipe, &sharedHandle, sizeof(sharedHandle), &bytesWritten, nullptr);

客户端代码 #

ComPtr<ID3D11Texture2D> sharedTex;
HRESULT hr = device->OpenSharedResource(
    sharedHandle,
    __uuidof(ID3D11Texture2D),
    reinterpret_cast<void**>(sharedTex.GetAddressOf())
);

请问是否可以从UMD向常规用户态进程共享D3D11纹理？
