The ACPI IORT table provides information that allows instantiating ARM SMMU devices and carrying out id mappings between components on ARM based systems (devices, IOMMUs, interrupt controllers). http://infocenter.arm.com/help/topic/com.arm.doc.den0049b/DEN0049B_IO_Remapping_Table.pdf Building on basic IORT support, this patchset enables ARM SMMUs support on ACPI systems. Most of the code is aimed at building the required generic ACPI infrastructure to create and enable IOMMU components and to bring the IOMMU infrastructure for ACPI on par with DT, which is going to make future ARM SMMU components easier to integrate.

I rebased my platform MSI, interrupt producer and mbi-gen patch set on top of yours, and test it on Hisilicon D03 board with SMMv3 enabled, USB and SAS are working properly with configuration in IORT (yes, I need to add patch from Robin - iommu/arm-smmu: Don't inadvertently reject multiple SMMUv3s), Tested-by: Hanjun Guo <hanjun.guo@xxxxxxxxxx> Thanks Hanjun -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
