This documentation is a high level overview to explain the basics
of Linux running as a guest on Hyper-V. The intent is to document
the forest, not the trees. The Hyper-V Top Level Functional Spec
provides conceptual material and API details for the core Hyper-V
hypervisor, and this documentation provides additional info on
how that functionality is applied to Linux. Also, there's no
public documentation on VMbus or the VMbus synthetic devices, so
this documentation helps fill that gap at a conceptual level. This
documentation is not API-level documentation, which can be seen
in the code and associated comments.
More topics will be added in future patches, including:
* Miscellaneous synthetic devices like KVP, timesync, VSS, etc.
* Virtual PCI support
* Isolated/Confidential VMs
If you think I'm missing a topic that fits into the overall
approach as described, feel free to suggest text, or let me
know and I can add it to my list.

There is an UIO driver for Hyper-V. I think that falls under this
category. Not sure if that's on your radar to cover?
Thanks,

Good point. I'll add it to my list. :-)
