[Qemu-devel] [RFC PATCH 0/8] Shared Virtual Memory virtualization for VT-d

[Liu, Yi L]

Hi,

This patchset introduces SVM virtualization for intel_iommu in
IOMMU/VFIO. The total SVM virtualization for intel_iommu touched
Qemu/IOMMU/VFIO.

Another patchset would change the Qemu. It is "[RFC PATCH 0/20] Qemu:
Extend intel_iommu emulator to support Shared Virtual Memory"

In this patchset, it adds two new IOMMU APIs and their implementation
in intel_iommu driver. In VFIO, it adds two IOCTL cmd attached on
container->fd to propagate data from QEMU to kernel space.

[Patch Overview]
* 1 adds iommu API definition for binding guest PASID table
* 2 adds binding PASID table API implementation in VT-d iommu driver
* 3 adds iommu API definition to do IOMMU TLB invalidation from guest
* 4 adds IOMMU TLB invalidation implementation in VT-d iommu driver
* 5 adds VFIO IOCTL for propagating PASID table binding from guest
* 6 adds processing of pasid table binding in vfio_iommu_type1
* 7 adds VFIO IOCTL for propagating IOMMU TLB invalidation from guest
* 8 adds processing of IOMMU TLB invalidation in vfio_iommu_type1

Best Wishes,
Yi L
