"A mismatch between the PNP/INF version and the KMD file version on the graphics adapter has been detected"

Question

我一直在测试 UMDF IddCx 视频驱动程序，这条消息刚刚开始出现（在 devcon.exe 安装之后...）以及 WinDbg 中的断点：

(DriverEntry and EVT_WDF_DRIVER_DEVICE_ADD handlers succeed as they did prior to this error message)
    .
    .
    .
<==CDriver::OnWdfDriverDeviceAdd [status: STATUS_SUCCESS]

A mismatch between the PNP/INF version and the KMD file version on the graphics adapter has been detected. The adapter will fail to start.
(WinDbg breaks here -- see stack below)

==>CAdapter::OnWdfDeviceD0Entry(hWdfDevice: <hWdfAdapterDevice>, previousState: 5)
    .
    .
    .

堆栈信息（Windows 10 Pro | 测试模式 | 构建 19041.vb_release.191206-1406）：

我不明白这是什么意思；我没有更改 INF 中的任何内容，这是一个 UMDF 驱动程序，那么它指的是什么“KMD 文件版本”？我搜索了消息本身以及 DpiFdoValidateKmdAndPnpVersionMatch，但结果是空的。

编辑：（添加版本信息）

Windows Version Info:
---------------------
Edition ....... Windows 10 Pro
Version ....... 20H2
Installed on .. 1/5/2021
OS build ...... 19042.685
Experience .... Windows Feature Experience Pack 120.2212.551.0

任何人都可以阐明这一点吗？

Answer 1

该符号在 1909 年不存在，因此该符号必须是 20H2 的新增内容
无论如何，有问题的字符串确实存在于 1909

故障应该在 IoQueryFullDriverPath() 和 GetFileVersion() 之后传播
int3 在 DebugPrintEx()
之后被硬编码有问题的函数 ADAPTER_RENDER::Initialize() 正在与 'QCOM' 等

等硬编码 DWORDS 进行大量比较

C:\> radare2 -Q -qq -c "fs strings;f~mismatch" c:\Windows\System32\drivers\dxgkrnl.sys

我只是在谷歌上搜索与 inf 和 GetKmdFileVersion 相关的内容，看来您需要提供特定的版本字符串 see if you comply with this

特别引用文档

Drivers will report WDDM 2.1 support through DXGK_DRIVERCAPS::WDDMVersion with a new version constant: DXGK_WDDMVERSION::DXGKDDI_WDDMv2_1 = 0x2100 Dxgkrnl will not use the WDDMVersion cap as a way to determine which new features are supported—that task will be left to other caps or DDI presence. However, if the driver reports WDDM 2.1 support through the WDDMVersion cap, dxgkrnl will validate that caps or DDIs required by WDDM 2.1 are present and fail to create the adapter if they are not. Inconsistent caps will result in failure to create adapter or segment.

Answer 2

请尝试添加以下注册表项：

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\DisableVersionMismatchCheck = 1 [DWORD 类型]

"A mismatch between the PNP/INF version and the KMD file version on the graphics adapter has been detected"

"A mismatch between the PNP/INF version and the KMD file version on the graphics adapter has been detected"
