使用 KeyedMutex 的 SlimDX 变形设备

Question

我通过 KeyedMutex 使用 Direct2D 和 DirectX11。如果我使用的是硬件设备，一切都很好。当我默认使用 Warp 设备时，我在创建 Texture2D 对象时遇到问题，我收到错误消息“Direct3D11Exception: E_OUTOFMEMORY: Ran out of memory”

这些是负责的行：

    SlimDX.Direct3D11.Texture2DDescription tds = SlimDX.Direct3D11.Texture2D.FromSwapChain(swapChain, 0).Description;
    tds.BindFlags |= BindFlags.ShaderResource;
    tds.SampleDescription = new SampleDescription(1, 0);
    tds.OptionFlags |= ResourceOptionFlags.KeyedMutex;
    textureD3D11 = new SlimDX.Direct3D11.Texture2D(device, tds);

再一次，使用硬件设备一切都很好，而不是 Warp。当我对 PIX 运行它时，我看到了这个：

ID3D11Device:CreateTexture2D(0x0FD1E330, NULL, 0x0FD1E32C --> NULL)

这是使用 Warp 驱动程序，但是当我使用硬件时，最后一个 NULL 不是 NULL，它是一个指向 D3D11 Texture2D 对象的实际指针。

有什么想法吗？我知道我在这里没有包含太多代码，但我希望有人知道这是什么而不必发布整个 DX 例程。如果需要，我会的。

我确实使用调试和 10.1 DX。调试输出如下：

Using ID3D11Debug::ReportLiveDeviceObjects with D3D11_RLDO_DETAIL will help drill into object lifetimes. Objects with ExtRef=0 and IntRef=0 will be eventually destroyed through typical Immediate Context usage. However, if the application requires these objects to be destroyed sooner, ClearState followed by Flush on the Immediate Context will realize their destruction.

Warp 设备在 Windows 7 中最多只能支持功能级别 10.1。

此外，如果您想获得正确的错误消息，请使用调试选项标志创建您的设备。

然后在项目属性的调试选项卡中，勾选“启用非托管代码调试”

现在您调试您的调试输出中将有更清晰的通知。
