Subject: [PATCH v2 0/4] iommu/vt-d: Add prq report and response support

Hi,

This series adds page request event reporting and response support to
the Intel IOMMU driver. This is necessary when the page requests must
be processed by any component other than the vendor IOMMU driver. For
example, when a guest page table was bound to a PASID through the
iommu_ops->sva_bind_gpasid() api, the page requests should be routed to
the guest, and after the page is served, the device should be responded
with the result.

Your review comments are very appreciated.

Best regards,
baolu

Change log:
v1->v2:
  - v1 posted at https://lkml.org/lkml/2020/6/27/387
  - Remove unnecessary pci_get_domain_bus_and_slot()
  - Return error when sdev == NULL in intel_svm_page_response()

Lu Baolu (4):
  iommu/vt-d: Refactor device_to_iommu() helper
  iommu/vt-d: Add a helper to get svm and sdev for pasid
  iommu/vt-d: Report page request faults for guest SVA
  iommu/vt-d: Add page response ops support
