Hi,

Kindly ping, any comments?

This series looks fine to me. I will queue it (with the typo in the
subject fixed) for iommu/next if no further concerns. Thanks!

Thanks

Hi,

When we add pasid support in QEMU for passthrough device, we found
PASID attachment to a nested parent domain with dirty tracking failed.

It's because PASID-level dirty tracking is not there yet, by adding it,
we can enable PASID attachment to such domain.

Thanks
Zhenzhong
