摘要： A virtual display system, compatible with Windows Display Driver Model (WDDM), facilitates extending a display virtually, to any display target, such as a window on the primary display, a tablet, or another personal computer altogether. The virtual WDDM display system device has a PCI filter driver, a virtual device user mode driver and a virtual device kernel mode driver. The virtual WDDM display system interacts with a physical WDDM display device, which it uses as a surrogate renderer. The PCI filter driver is used to force enumeration of a virtual display device. The virtual device kernel mode driver uses chained callbacks at increasing IRQ levels for simulating an interrupt from a real hardware device. Continuous segments in memory are used to simulate video memory on a physical display device. DirectX extensions are used to facilitate expectations at the hardware level.
摘要翻译：与Windows显示驱动程序模型（WDDM）兼容的虚拟显示系统有助于将显示器虚拟地扩展到任何显示目标，如主显示器，平板电脑或其他个人计算机上的窗口。虚拟WDDM显示系统设备具有PCI过滤器驱动程序，虚拟设备用户模式驱动程序和虚拟设备内核模式驱动程序。虚拟WDDM显示系统与物理WDDM显示设备交互，WDD显示设备用作代理渲染器。 PCI过滤器驱动程序用于强制虚拟显示设备的枚举。虚拟设备内核模式驱动程序在增加IRQ级别时使用链接回调来模拟来自真实硬件设备的中断。内存中的连续片段用于模拟物理显示设备上的视频内存。 DirectX扩展用于在硬件级别方便预期。
