Hi all, At long last I've finished the big SMMUv2 rework, so here's everything all together for a v5. As a quick breakdown: Patches 1-3 are the core PCI part, all acked and ready to go. No code changes from v4. Patch 4 is merely bugfixed from v4 for simplicity, as I've not yet managed to take as close a look at Lorenzo's follow-on work as I'd like. Patches 5-7 (SMMUv3) are mostly unchanged beyond a slight tweak to #5. Patches 8-17 are the all-new SMMUv2 rework. Patch 18 goes along with the fix already in 4.8-rc3 to help avoid 64-bit DMA masks going wrong now that DMA ops will be enabled. Finally, patch 19 addresses the previous problem of having to choose between DMA ops or working MSIs. This is currently at the end as moving it before #17 would require a further interim SMMUv2 patch, and a 19-patch series is already quite enough... I've pushed out a branch based on iommu/next to the usual place: git://linux-arm.org/linux-rm iommu/generic-v5 Thanks, Robin. --- Mark Rutland (1): Docs: dt: add PCI IOMMU map bindings Robin Murphy (18): of/irq: Break out msi-map lookup (again) iommu/of: Handle iommu-map property for PCI iommu/of: Introduce iommu_fwspec iommu/arm-smmu: Implement of_xlate() for SMMUv3 iommu/arm-smmu: Support non-PCI devices with SMMUv3 iommu/arm-smmu: Set PRIVCFG in stage 1 STEs iommu/arm-smmu: Handle stream IDs more dynamically iommu/arm-smmu: Consolidate stream map entry state iommu/arm-smmu: Keep track of S2CR state iommu/arm-smmu: Refactor mmu-masters handling iommu/arm-smmu: Streamline SMMU data lookups iommu/arm-smmu: Add a stream map entry iterator iommu/arm-smmu: Intelligent SMR allocation iommu/arm-smmu: Convert to iommu_fwspec Docs: dt: document ARM SMMU generic binding usage iommu/arm-smmu: Wire up generic configuration support iommu/arm-smmu: Set domain geometry iommu/dma: Add support for mapping MSIs .../devicetree/bindings/iommu/arm,smmu.txt | 63 +- .../devicetree/bindings/pci/pci-iommu.txt | 171 ++++ drivers/iommu/Kconfig | 2 +- drivers/iommu/arm-smmu-v3.c | 347 ++++---- drivers/iommu/arm-smmu.c | 952 ++++++++++----------- drivers/iommu/dma-iommu.c | 141 ++- drivers/iommu/of_iommu.c | 95 +- drivers/irqchip/irq-gic-v2m.c | 3 + drivers/irqchip/irq-gic-v3-its.c | 3 + drivers/of/irq.c | 78 +- drivers/of/of_pci.c | 102 +++ include/linux/dma-iommu.h | 9 + include/linux/of_iommu.h | 15 + include/linux/of_pci.h | 10 + 14 files changed, 1208 insertions(+), 783 deletions(-) create mode 100644 Documentation/devicetree/bindings/pci/pci-iommu.txt -- 2.8.1.dirty -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
