There are several IOMMU/DMA related new structures introduced since 1803. However I seems can't find the related samples.
Are they only used to support VBS? Or can be used in some more flexible way, i.e. control the device DMA by a platform driver in hyper-v OFF mode?

According to your description, seems the issue is more related to hardward wdk, since Windows 10 virtualization forum is mainly about Hyper V role on Windows 10, wdk is out of windows-10-virtualization forum scope, so, I will remove the tag windows-10-virtualization for you, thanks for your understanding!
Best Regards,

I'll keep current status for a while and see if need add the tag back.
Thanks for your quick response.
