[v2,0/8] SMMU handling for PCIe Passthrough on ARM

Message

Stewart Hildebrand May 11, 2023, 7:16 p.m. UTC

This series introduces SMMU handling for PCIe passthrough on ARM. These patches
are independent from (and don't depend on) the vPCI reference counting/locking
work in progress, and should be able to be upstreamed independently.

v1-v2:
* phantom device handling
* shuffle around iommu_add_dt_pci_device()

Oleksandr Andrushchenko (1):
  xen/arm: smmuv2: Add PCI devices support for SMMUv2

Oleksandr Tyshchenko (4):
  xen/arm: Move is_protected flag to struct device
  iommu/arm: Add iommu_dt_xlate()
  iommu/arm: Introduce iommu_add_dt_pci_device API
  pci/arm: Use iommu_add_dt_pci_device()

Rahul Singh (1):
  xen/arm: smmuv3: Add PCI devices support for SMMUv3

Stewart Hildebrand (2):
  iommu/arm: iommu_add_dt_pci_device phantom handling
  RFC: pci/arm: don't do iommu call for phantom functions
