[PATCH 0/3] iommupt/vtd: Support dirty tracking on PASID

[Zhenzhong Duan <zhenzhong.duan@intel.com>]

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
