[Qemu-devel] [PATCH 0/3] memory: add IOMMU notifier type

[Peter Xu]

In the thread:

  https://lists.gnu.org/archive/html/qemu-devel/2016-09/msg00254.html

Alex proposed a way for vhost DMAR to be enabled without breaking
existing protections on vIOMMU and device assignments. This series
tried to implement the idea, by introducing a IOMMU notifier type for
each IOMMU memory region.

Thanks,

Peter Xu (3):
  memory: add one flag for IOMMU notifier
  memory: add iommu_notify_flag
  intel_iommu: allow IOMMU_NONE typed notifiers
