FWIW Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> for the patches I didn't comment on in this version as I couldn't find anything to comment about ;) Thanks Jonathan > > Jean-Philippe Brucker (13): > iommu/arm-smmu-v3: Drop __GFP_ZERO flag from DMA allocation > dt-bindings: document PASID property for IOMMU masters > iommu/arm-smmu-v3: Support platform SSID > ACPI/IORT: Support PASID for platform devices > iommu/arm-smmu-v3: Prepare arm_smmu_s1_cfg for SSID support > iommu/arm-smmu-v3: Add context descriptor tables allocators > iommu/arm-smmu-v3: Add support for Substream IDs > iommu/arm-smmu-v3: Propate ssid_bits > iommu/arm-smmu-v3: Handle failure of arm_smmu_write_ctx_desc() > iommu/arm-smmu-v3: Add second level of context descriptor table > iommu/arm-smmu-v3: Improve add_device() error handling > PCI/ATS: Add PASID stubs > iommu/arm-smmu-v3: Add support for PCI PASID > > .../devicetree/bindings/iommu/iommu.txt | 6 + > drivers/acpi/arm64/iort.c | 18 + > drivers/iommu/arm-smmu-v3.c | 462 +++++++++++++++--- > drivers/iommu/of_iommu.c | 6 +- > include/linux/iommu.h | 2 + > include/linux/pci-ats.h | 3 + > 6 files changed, 437 insertions(+), 60 deletions(-) >
Add support for Substream ID and PASIDs to the SMMUv3 driver. Changes since v2 [1]: * Split preparatory work into patches 5, 6, 8 and 9. * Added patch 1. Not strictly relevant, but since we're moving the DMA allocations and adding a new one, we might as well clean the flags first. * Fixed a double free reported by Jonathan, and other small issues. * Added patch 12. Upstream commit c6e9aefbf9db ("PCI/ATS: Remove unused PRI and PASID stubs") removed the unused PASID stubs. Since the SMMU driver can be built without PCI, the stubs are now needed.
