显示Display

Windows 10 版本 1809 中的“显示”驱动程序开发的更新包括：Updates to Display driver development in Windows 10, version 1809 include the following:

• 光线跟踪：为了支持硬件加速的光线跟踪，我们在开发 Direct3D API 的同时开发了新的 Direct3D DDI。Raytracing New Direct3D DDI's were created in parallel of Direct3D API's, in order to support hardware-accelerated raytracing. 示例 DDI 包括：PFND3D12DDI_BUILD_RAYTRACING_ACCELERATION_STRUCTURE_0054、PFND3D12DDI_COPY_RAYTRACING_ACCELERATION_STRUCTURE_0054。Example DDIs include: PFND3D12DDI_BUILD_RAYTRACING_ACCELERATION_STRUCTURE_0054, PFND3D12DDI_COPY_RAYTRACING_ACCELERATION_STRUCTURE_0054. 有关光线跟踪的详细信息，请参阅宣布推出 Microsoft DirectX 光线跟踪。For more info about raytracing, see Announcing Microsoft DirectX Raytracing.

• 通用驱动程序要求：WDDM 2.5 驱动程序需要确保其 DirectX11 UMD、DirectX12 UMD、KMD 以及这些组件加载的其他任何 DLL 遵守通用 API。Universal Driver Requirements WDDM 2.5 drivers will need to ensure their DirectX11 UMD, DirectX12 UMD, KMDs, and any other DLL loaded by these components, adhere to the Universal API.

• 仅限 SRV 的平铺资源层 3：在 Windows 10 版本 1809 中，GPU 能够更以更低的正交性支持平铺资源层 3 功能。SRV-Only Tiled Resource Tier 3 In Windows 10, version 1809, Tiled Resource Tier 3 capabilities can be supported less-orthogonally by GPUs. Direct3D12 现在支持稀疏体积纹理，而无需进行无序访问和渲染器目标操作。Direct3D12 now supports sparse volume textures without requiring unordered-access and render-target operations. 仅限 SRV 的平铺资源层 3 是适合在第 2 层和第 3 层之间部署的概念层。SRV-Only Tiled Resource Tier 3 is a conceptual tier that fits between Tier 2 and Tier 3. 与当前的正交平铺资源层 3 一样，硬件支持是可选的。Hardware support is optional, just like orthogonal Tiled Resource Tier 3 support currently is. 但是，仅限 SRV 的平铺资源层 3 支持是一个超集层，需要平铺资源层 2 的支持。But, supporting SRV-Only Tiled Resource Tier 3 is a super-set tier that requires support for Tiled Resource Tier 2.

  已播发正交平铺资源层 3 支持的驱动程序只需更新其驱动程序即可支持最新的“选项上限”DDI 结构版本。Drivers that already advertise support for orthogonal Tiled Resource Tier 3 merely have to update their drivers to support the latest “options caps” DDI structure version. 对于已能支持正交平铺资源层 3 的任何硬件，运行时会将仅限 SRV 的平铺资源层 3 支持播发到应用程序。The runtime will advertise SRV-Only Tiled Resource Tier 3 support to applications for any hardware that already supports orthogonal Tiled Resource Tier 3.

• 渲染通道：已添加渲染通道功能来实现以下目的：Render Pass The Render Pass feature was added to:

  • 在现有的驱动程序上运行新的 API。Allow new APIs to be run on existing drivers.
  • 使用户模式驱动程序能够选择最佳的渲染路径，且不会严重降低 CPU 的性能。Allow user mode drivers to choose optimal rendering path without heavy CPU penalty.

• 元命令：元命令是代表 IHV 加速算法的 Direct3D12 对象。Meta-commands A Meta-command is Direct3D12 object that represents an IHV-accelerated algorithm. 它是对驱动程序实现的命令生成器的不透明引用。It’s an opaque reference to a command generator implemented by the driver. 元命令的更新包括描述符表绑定和纹理绑定。Meta-command updates include Descriptor Table Binding and Texture binding. 请参阅 D3D12DDI_META_COMMAND_PARAMETER_TYPE 和 D3D12DDIARG_META_COMMAND_PARAMETER_DESC。See D3D12DDI_META_COMMAND_PARAMETER_TYPE and D3D12DDIARG_META_COMMAND_PARAMETER_DESC.

  • 启用图形管道算法Enable Graphics Pipeline Algorithms

• HDR 亮度补偿：引入了新的 SDR 亮度提升技术，以将 SDR 内容的参考白色部分提高到用户所需的值，这样就能够以 200-240 典型尼特值再现 SDR 内容，相当于用户预期的 SDR 显示效果。HDR Brightness Compensation A new SDR brightness boost was introduced to raise the reference white of SDR content to the user-desired value, allowing SDR content to be reproduced to a typical 200-240 nits, which is equivalent to what users have expected for SDR displays. SDR 亮度提升在两个方面会影响总体 Brightness3 行为：SDR brightness boost affects overall Brightness3 behavior in two ways:

  1. 只能在预先混合的前提下，针对 SDR 内容应用此提升。This boost is applied pre-blend only on SDR content. HDR 内容不受影响。HDR content is not affected. 同时，对于大多数笔记本电脑/brightness3 方案，用户预期所有内容（SDR 和 HDR）可调整。Meanwhile, for most laptop/brightness3 scenarios, users expect all content (SDR and HDR) to be adjusted.

  2. 当 OS 中的 Brightness3 堆栈确定所需的尼特值时，并不知道已经应用了 SDR 提升。When the Brightness3 stack in the OS determines the desired nits value, it is not aware of the already applied SDR boost.

     驱动程序必须对来自 HDR Brightness3 DDI 的所需尼特值应用补偿。The driver must then apply a compensation to the desired nits value coming from Brightness3 DDIs for HDR. 由于图形驱动程序（和下游的 TCON 等）将会修改内容的像素值以获取所需的尼特值，因此，还应该对应用程序通过 D3DDDI_HDR_METADATA_HDR10 提供的 HDR 内容元数据或者通过 DxgkDdiSetTargetAdjustedColorimetry 提供的 OS 默认值应用补偿。Since Graphics drivers (and downstream TCON etc.) will be modifying the pixel values of the content to get desired nits value, there should also be a compensation applied to the HDR content metadata as provided by the applications via D3DDDI_HDR_METADATA_HDR10 or OS defaults via DxgkDdiSetTargetAdjustedColorimetry. 由于图形驱动程序 (TCON) 负责修改像素数据，因此驱动程序需负责补偿 HDR 内容元数据。Since Graphics driver (TCONs) are responsible for modifying the pixel data, it is the driver’s responsibility to compensate the HDR content metadata.

• HDR 像素格式支持：此内核模式设备驱动程序接口 (DDI) 更改包含在 WDDM 2.5 中，公开了驱动程序/设备报告的新功能，提供有关驱动程序/设备支持的 HDR 功能的信息。HDR Pixel Format Support This kernel mode device driver interface (DDI) change is part of WDDM 2.5 to expose new capabilities to be reported by driver/device, providing information regarding the HDR functionality supported by the driver/device.

  目前，OS 根据从 DdiUpdateMonitorLinkInfo 读取的 DXGK_MONITORLINKINFO_CAPABILITIES 结构的 HighColorSpace 位确定驱动程序/设备是否支持 HDR。Currently, OS determines if the driver/device supports HDR based on the HighColorSpace bit of the DXGK_MONITORLINKINFO_CAPABILITIES structure as read from DdiUpdateMonitorLinkInfo. HighColorSpace 位提供以 HDR 模式运行的驱动程序/链接/监视功能的组合。The HighColorSpace bit gives a combination of driver/link/monitor capability to run in HDR mode.

  驱动程序报告的 HDR 功能现在包括驱动程序/设备级功能，可让 OS 知道驱动程序/设备是支持真正的 HDR（即 FP16HDR），还是仅支持受限形式的 HDR（即 ARGB10HDR），相关定义如下：The HDR capabilities reporting by the driver now includes a Driver/Device level capabilities, which will let OS know if the Driver/Device supports true HDR (i.e. FP16HDR), or only supports a limited form of HDR (i.e. ARGB10HDR), as defined below:

  • FP16HDR：驱动程序/设备可将 FP16 像素格式图面与 scRGB/CCCS 色彩空间结合使用，并在运行扫描输出管道期间应用 PQ/2084 编码和 BT.2020 原色，以将输出信号转换为 HDR10。FP16HDR: Driver/device can take FP16 pixel format surfaces with scRGB/CCCS colorspace and apply PQ/2084 encoding and BT.2020 primaries during scanout pipeline to convert output signal to HDR10.

  • ARGB10HDR：驱动程序/设备可以采用已经过 PQ/2084 编码的 ARGB10 像素格式图面，并扫描输出 HDR10 信号。ARGB10HDR: Driver/device can take ARGB10 pixel format surfaces which are already PQ/2084 encoded and scan out HDR10 signal. 驱动程序/设备无法处理上面定义的 FP16HDR，也无法处理 scRGB FP16 的扩展数值范围。Driver/device can’t handle FP16HDR as defined above or cannot handle the extended numeric range of scRGB FP16.

    图形驱动程序只能报告 FP16HDR 或 ARGB10HDR 的支持，因为它们并不真正采用超集/子集配置；如果同时报告支持 FP16HDR 和 ARGB10HDR，则 OS 会使启动适配器失败。Graphics drivers can only report support for either FP16HDR or ARGB10HDR as they are not really superset/subset configurations and OS will fail the Start Adapter if both are reported as supported at the same time. 请参阅 DXGK_MONITORLINKINFO_CAPABILITIES 和 _DXGK_DISPLAY_DRIVERCAPS_EXTENSION。See DXGK_MONITORLINKINFO_CAPABILITIES and _DXGK_DISPLAY_DRIVERCAPS_EXTENSION.

• SDR 白水平：内核模式设备驱动程序接口的更改包括将新的参数添加到现有的 DDI，使图形驱动程序知道 OS 复合器对所有在 HDR 模式下显示的 SDR 内容应用的“SDR 白水平”值。SDR White Level A kernel mode device driver interface change includes adding new parameters to existing DDIs to let the Graphics drivers know the “SDR white level” value that is being applied by the OS compositor for all the SDR content, for a display which is running in HDR mode. 请参阅“_DXGK_COLORIMETRY”。See _DXGK_COLORIMETRY.

相机Camera

对相机驱动程序开发的更新包括：Updates to Camera driver development include:

• 适用于 UVC 设备的 DShow (DirectShow) 桥实施指南 - 有关配置符合 USB 视频类 (UVC) 规范的相机和设备的 DShow 桥的实施指南。DShow (DirectShow) Bridge implementation guidance for UVC devices - Implementation guidance for configuring DShow Bridge for cameras and devices that comply with the USB Video Class (UVC) specification. 平台使用 USB 总线标准中的 Microsoft OS 描述符来配置 DShow 桥。The platform uses Microsoft OS Descriptors from the USB bus standard to configure DShow Bridge. 扩展属性 OS 描述符是 USB 标准描述符的扩展，USB 设备使用它来返回尚未通过标准规范启用的 Windows 特定设备属性。The Extended Properties OS Descriptors are an extension of USB standard descriptors and are used by USB devices to return Windows specific device properties that are not enabled through standard specifications.
• 全景相机视频捕获 - 使用现有的 MediaCapture API 提供全景相机预览、捕获和记录支持。360 camera video capture - Provides support for 360 camera preview, capture, and record with existing MediaCapture APIs. 平台可以使用此功能来公开球形帧源（例如 equirectangular 帧），使应用能够检测和处理全景视频相机流，以及提供全景拍摄体验。This enables the platform to expose spherical frame sources (for example, equirectangular frames ), enabling apps to detect and handle 360 video camera streams as well as to provide a 360 capture experience.

显示Display

下面是对 Windows 10 版本 1803 中的“显示”驱动程序开发的更新：The following are updates to Display driver development in Windows 10, version 1803:

• 间接显示 UMDF 类扩展 - 间接显示驱动程序可将 SRM 传递给渲染 GPU，并提供一种机制用于查询所用的 SRM 版本。Indirect Display UMDF class extension - The Indirect Display driver can pass the SRM to the rendering GPU and have a mechanism to query the SRM version being used.

• 基于 IOMMU 硬件的 GPU 隔离支持 - 通过限制 GPU 访问系统内存来提高安全性。IOMMU hardware-based GPU isolation support - Increases security by restricting GPU access to system memory.

• GPU 半虚拟化支持 - 可让显示驱动程序在 Hyper-V 虚拟化环境中提供渲染功能。GPU paravirtualization support - Enables display drivers to provide rendering capabilities to Hyper-V virtualized environments.

• 亮度 - 提供新的亮度接口来支持多个显示器，这些显示器可设置为基于校准尼特值的亮度水平。Brightness - A new brightness interface to support multiple displays that can be set to calibrated nit-based brightness levels.

• D3D11 位流加密 - 在 D3D11 中提供更多的 GUID 和参数来支持公开包含 8 或 16 字节初始化矢量的 CENC、CENS、CBC1 和 CBCS。D3D11 bitstream encryption - Additional GUIDS and parameters to D3D11 to support exposing CENC, CENS, CBC1, and CBCS with 8 or 16 byte initialization vectors.

• D3D11 和 D3D12 视频解码直方图 - 借助照度直方图，媒体团队可以利用直方图的固定功能硬件来改善 HDR/EDR 方案的音调映射质量。D3D11 and D3D12 video decode histogram - A luminance histogram allows the media team to leverage fixed function hardware for histogram to improve tone mapping quality for HDR/EDR scenarios. 当这些方案已经饱和使用了 GPU 或者想要启用并行处理时，固定功能硬件非常有用。Fixed function hardware is useful when GPU is already saturated in these scenarios and to enable parallel processing. 此功能是可选的。仅当固定功能硬件可用时，才应该实现此功能。This feature is optional and should only be implemented if fixed function hardware is available. 不应配合 3D 或计算方案实现此功能。This feature should not be implemented with 3D or Compute.

• D3D12 视频解码现在支持解码层 II，指示驱动程序支持纹理阵列，可在分辨率发生更改时，让应用程序分摊分配成本并减少峰值内存使用量。 D3D12 video decode now supports Decode Tier II, indicating driver supports Array of Textures that enable applications to amortize allocation cost and reduce peak memory usage during resolution change.

• GPU 递色支持 - 驱动程序可以报告给定计时模式下针对网络信号执行递色的能力。GPU dithering support - Drivers can report the ability to perform dithering on the wire signal for a given timing mode. 这样，当所需的位深度效率高于监视链路实际所能提供的效率时（例如需要 HDR10 而不是 HDMI 2.0），OS 可以显式请求递色。This allows the OS to explicitly request dithering in scenarios where a higher effective bit depth is needed than is physically available on the monitor link, for example for HDR10 over HDMI 2.0.

• 后处理颜色增强覆盖 - 可让 OS 请求驱动程序暂时禁用任何增强或更改显示颜色的后处理功能。Post-processing color enhancement override - Adds the ability for the OS to request that the driver temporarily disable any post-processing that enhances or alters display colors. 这可以支持如下所述的方案：特定的应用程序能够以比色方式在显示器上实施准确的色彩行为，并安全地与 OEM 或 IHV 专属显示颜色增强功能共存。This is to support scenarios where specific applications want to enforce colorimetrically accurate color behavior on the display, and safely coexist with OEM or IHV-proprietary display color enhancements.

• Direct3D12 和视频 - 新的 API 和 DDI 提供对以下功能的访问：Direct3D12 and Video - New API and DDI to provide access to the following capabilities:

  • 硬件加速的视频解码Hardware accelerated video decoding
  • 内容保护Content Protection

DDI 是现有 DxgkDdiQueryAdapterInfo DDI 的扩展，应受 DXGKDDI_INTERFACE_VERSION >= DXGKDDI_INTERFACE_VERSION_WDDM2_3 的所有驱动程序的支持，包括仅限内核模式显示的驱动程序和间接显示驱动程序。The DDI is an extension of existing DxgkDdiQueryAdapterInfo DDI and shall be supported by all drivers with DXGKDDI_INTERFACE_VERSION >= DXGKDDI_INTERFACE_VERSION_WDDM2_3, including kernel mode display only drivers and indirect display drivers.

• GPU 性能数据 - DdiQueryAdapterInfo 的扩展将公开温度、风扇速度、引擎和内存时钟速度、内存带宽、功耗和电压等信息GPU performance data - Extensions to DdiQueryAdapterInfo will expose information such as temperature, fan speed, clock speeds for engines and memory, memory bandwidth, power draw, and voltages

• 杂项 - 新的 SupportContextlessPresent 驱动程序上限可帮助 IHV 载入新驱动程序。Miscellaneous - A new SupportContextlessPresent driver cap to help IHV onboard new driver.

• 改进了 OS 中的外部/可移动 GPU 支持。Improvements to External/Removable GPU support in the OS. 作为改进支持的第一步，Dxgkrnl 需要确定 GPU 是否“可分离”，即可热插拔。As a first step to add better support, Dxgkrnl needs to determine if a GPU is “detachable”, i.e. hot-pluggable. 对于 RS4，我们希望利用此方面的驱动程序信息，而不是生成自己的基础结构。For RS4 we would like to leverage the driver’s knowledge about this instead of building our own infrastructure. 为此，我们将在 DXGK_ DRIVERCAPS 结构中添加“Detachable”位。For this purpose, we are adding a “Detachable” bit to DXGK_ DRIVERCAPS struct. 如果适配器可热插拔，则在适配器初始化期间，驱动程序会设置此位。Driver will set this bit during adapter initialization if the adapter is hot-pluggable.

• 显示诊断 - 内核模式设备驱动程序接口 (DDI) 已发生更改，允许显示控制器的驱动程序向 OS 报告诊断事件。Display Diagnostics - Kernel mode device driver interface (DDI) changes to allow the driver for a display controller to report diagnostic events to the OS. 这就提供了一个通道来让驱动程序记录事件，否则 OS 看不到这些事件，因为事件不是 OS 请求的响应，也不是 OS 需要应对的对象。This provides a channel through which the driver can log events which would otherwise be invisible to the OS as the events are not a response to an OS request or something the OS needs to react to.

• 共享图形电源组件 - 使非图形驱动程序能够参与图形设备的电源管理。Shared graphics power components - Allows non-graphics drivers to participate in the power management of a graphics device. 非图形驱动程序将配合图形驱动程序，使用某个驱动程序接口来管理其中一个或多个共享的电源组件。A non-graphics driver will use a driver interface to manage one or more of these shared power components in coordination with the graphics driver.

• 共享纹理改进 - 包括增加了可在进程和 D3D 设备之间共享的纹理类型。Shared texture improvements - Includes increasing the types of textures that can be shared across processes and D3D devices. 此设计使得帧服务器 OS 组件能够以极少量的内存复制来支持单色。This design enables the frame server OS component to support monochrome with minimal memory copying.

Windows 内核Windows kernel

本部分介绍 Windows 10 版本 1803 中的 Windows 内核驱动程序开发的新增功能和已更新的功能。This section describes the new and updated features for Windows kernel driver development in Windows 10, version 1803.

已将一组新 API 添加到工具包，使第三方能够创建其自己的 KDNET 扩展模块或 KdSerial 传输层。A set of new APIs has been added to the kit to enable third parties to create their own KDNET extensibility modules or KdSerial transport layers. 有关示例代码，请参阅 Debuggers 文件夹中的“内核传输示例”(ddk\samples\kdserial and ddk\samples\kdnet)。For sample code, see “Kernel Transport Samples” (ddk\samples\kdserial and ddk\samples\kdnet) in the Debuggers folder.

添加了相应的支持，为驱动程序提供一个可以存储文件状态的批准位置（操作系统知道该位置）。Support was added to provide drivers with a sanctioned location (that the operating system knows about) where they can store file state. 使用此方法时，系统可将该位置中的文件与某个设备或驱动程序相关联。With this approach, the system can associate files in that location with a device or driver.

有不同的位置用于存储特定于驱动程序内部组件或特定于设备的文件状态。There are distinct locations to store file states specific to the internals of a driver and specific to a device. 对于包含文件状态的驱动程序，可以确定写入到磁盘的状态是：For drivers that have file state, you can decide if the state written to disk is:

• 驱动程序状态 (IoGetDriverDirectory)：可能正在控制多个设备的驱动程序的全局状态，还是Driver state (IoGetDriverDirectory): global to the driver that might be controlling multiple devices), or

• 设备状态 (IoGetDeviceDirectory)：特定于驱动程序控制的单个设备，其他设备可能对类似的状态使用不同的值。Device state (IoGetDeviceDirectory): specific to the driver-controlled single device and other devices might have different values for similar state.

现在，当功能驱动程序 (FDO) 的相应 PCIe 设备处于 D3Cold 状态时，可与其他电源协商。Function drivers (FDO) can now negotiate additional power when their respective PCIe devices are in a D3Cold state. 这包括：This includes:

• 辅助电源要求 D3COLD_REQUEST_AUX_POWER。Auxiliary power requirement D3COLD_REQUEST_AUX_POWER.
• 核心电源导轨 D3COLD_REQUEST_CORE_POWER_RAIL。Core power rail D3COLD_REQUEST_CORE_POWER_RAIL.
• 在从 PCI Express 下游端口收到消息，到相应终结点或 PCI Express 下游端口在系统处于 ACPI 工作状态时转换为 D3cold 期间平台将 PERST# 断言到插槽的固定延迟时间要求。Requirement for a fixed delay time between the message is received at the PCI Express Downstream Port and the time the platform asserts PERST# to the slot during the corresponding endpoint’s or PCI Express Upstream Port’s transition to D3cold while the system is in an ACPI operational state. 请参阅 D3COLD_REQUEST_PERST_DELAY。See D3COLD_REQUEST_PERST_DELAY.

NT 服务以及内核模式和用户模式驱动程序可以使用 RtlRaiseCustomSystemEventTrigger 函数针对设备引发自定义触发器。NT services and kernel-mode and user-mode drivers can raise a custom trigger for a device by using the RtlRaiseCustomSystemEventTrigger function. 驱动程序开发人员拥有的自定义触发器通知系统事件代理使用自定义触发器标识符标识的触发器启动关联的后台任务。A custom trigger, owned by the driver developer, notifies system event broker to start an associated background task with it, which is identified by a custom trigger identifier.

现在，可以在激发通知时注册活动会话更改通知并获取回调。You can now register for active session change notification and get a callback when the notification is fired. 作为此通知的一部分，某些数据还会与调用方共享。As part of this notification, some data is also shared with the caller. 这些关联的数据通过 PO_SPR_ACTIVE_SESSION_DATA 结构传送。This associated data is delivered via the PO_SPR_ACTIVE_SESSION_DATA structure.
