Hi All:
We are researching how to add virtual VTD support for Xen HVM
guest. Current qemu has a basic virtual VTD support for Q35. I'd like to
confirm whether Xen supports Q35 or not. Can we reuse it for Xen? Thanks.
The motivations of adding virtual VTD support for Xen prepare for
1) Shared Vir
current code or not.
If yes, we can reuse Qemu virtual VTD for Xen with minor changes.
Thanks,
Stefano

Change since V1:
1) Move create/destroy vIOMMU and query vIOMMU capabilities to tool
stack.
2) Fix some code style issue.
This patchset is to deal with MSI interrupt remapping request when guest
updates MSI registers.
