Re: [PATCH v5 31/32] vfio: Synthesize vPASID capability to VM

[Cédric Le Goater]

Hello again,

In this case, I think we can extend HostIOMMUDevice and associated
class, to handle PASID support. Please rework this patch. I can
merge as a prereq change.

I had a go at extending the HostIOMMUDeviceClass in v4 here,
https://lore.kernel.org/qemu-devel/20250929133643.38961-26-skolothum...@nvidia.com/

Is something similar you have in mind here?

yes. That's the spirit. vfio-pci should be host IOMMU agnostic.

Thanks,

C.
