Was this work complete? (I'm truly uncertain, so not a rhetorical question.
IIRC SR-IOV is still unsupported, without which I'd not consider this work
complete.) In any event it's x86-only and hence would rather belong ...

I decided so because the patch series [1] seems to be fully merged.

Yes, it should be moved to x86. Based on the which files were changed during this patch series I decided that it should be
in hypervisor changes, but now I checked which changes specifically done and for Arm it was added basically only stubs in
libxl_arm.c.

I've spoken with Jiqian from AMD and the QEMU side is still pending to
be merged, so I'm not sure I would list it here yet.  Also AFAICT the
current work just enables passthrough from a PVH dom0 to an HVM domU,
but not to PV domUs.  This would need to be clarified.

Thanks, Roger.

Yes, I only added pci passthrough for HVM domUs when dom0 is PVH.
And the qemu patch isn't merged yet.
https://lore.kernel.org/xen-devel/BL1PR12MB58491271C360CE4345A915AFE7C02@BL1PR12MB5849.namprd12.prod.outlook.com/
I think we need to wait qemu patch merged and then you can add an entry like:
- On x86:
  - Support pci passthrough for HVM domUs when dom0 is PVH.

Thanks for clarifying. I will drop that for now.
