Message

Paul Durrant July 15, 2019, 12:37 p.m. UTC

This series is a mixture of tidying and some preparatory work for grouping
PCI devices for the purposes of assignment.

Paul Durrant (4):
  iommu / x86: move call to scan_pci_devices() out of vendor code
  pci: add all-device iterator function...
  iommu: introduce iommu_groups
  iommu / pci: re-implement XEN_DOMCTL_get_device_group...
