- Thread-topic: [PATCH v1 0/3] IPMMU handling for PCIe Passthrough on ARM
This series introduces IPMMU handling for PCIe passthrough on ARM. It includes
changes to pci-designware, pci-host-rcar and ipmmu-vmsa drivers to enable
configuring BDF->OSID->uTLB translation chain needed to pass different PCIe
devices to different domains.
Tested on RCar S4 Spider board.
Mykyta Poturai (2):
arm/pci: allow designware-based hosts to have private data
pci/rcar: implement OSID configuration for Renesas RCar Gen4 PCIe host
Oleksandr Tyshchenko (1):
iommu/ipmmu-vmsa: Implement basic PCIE-IPMMU OSID support
