同事给了一个DMP文件，说是在DELL笔记本中插入了一个HDMI线之后，再拔掉就BSOD了。
使用WINDBG自动分析提示是DMA问题:
DRIVER_VERIFIER_DMA_VIOLATION (e6)
An illegal DMA operation was attempted by a driver being verified.
Arguments:
Arg1: 0000000000000026, IOMMU detected DMA violation.
Arg2: ffffa30f56b8c060, Device Object of faulting device.
Arg3: 0000000000000000, Faulting information (usually faulting physical address).
Arg4: 0000000000000006, Fault type (hardware specific).
在https://learn.microsoft.com/zh-cn/windows-hardware/drivers/debugger/bug-check-0xe6--driver-verifier-dma-violation 中找到DRIVER_VERIFIER_DMA_VIOLATION的第一参数0x26信息：
0x26 IOMMU 检测到 DMA 冲突。
- 参数 2 - 故障设备的 Device 对象。
- 参数 3 - 故障信息 (通常会) 物理地址出错。
- 参数 4 - 故障类型 (特定于硬件的) 。
可以看到，一个奇怪的DMA物理地址竟然是Arg3: 0000000000000000。
PCI设备都是映射到BAR内存空间的，这个应该有通过BIOS分配的物理地址的。
通地参数2再分析一下是那个驱动及设备。
1.先找到设备对象信息

因其DeviceObjectExtension中存在DeviceNode中信息，其包括了设备的InstancePath，故可找到设备的硬件ID.
通过驱动信息可以看到是PCI驱动引起的。
