[v1,0/6] SMMU handling for PCIe Passthrough on ARM

Message

Stewart Hildebrand May 1, 2023, 8:02 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. I have
cherry-picked them from various downstream branches, rebased, and made minor
changes since the cherry-pick. Details are in the individual patches. The
changes are designated with "downstream->v1" even though this is the first time
the patches appear on the list.

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() instead of arch hook

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