The VFIO part is submitted separately. This is based on Jean-Philippe's [PATCH v14 00/10] iommu: I/O page faults for SMMUv3 https://www.spinics.net/lists/arm-kernel/msg886518.html (including the patches that were not pulled for 5.13) The IOMMU API is extended to support 2 new API functionalities: 1) pass the guest stage 1 configuration 2) pass stage 1 MSI bindings Then those capabilities gets implemented in the SMMUv3 driver. The virtualizer passes information through the VFIO user API which cascades them to the iommu subsystem. This allows the guest to own stage 1 tables and context descriptors (so-called PASID table) while the host owns stage 2 tables and main configuration structures (STE). Best Regards Eric This series can be found at: v5.12-rc6-jean-iopf-14-2stage-v15 (including the VFIO part in its last version: v13) The VFIO series is sent separately. History: Previous version: https://github.com/eauger/linux/tree/v5.11-stallv12-2stage-v14 v14 -> v15: - on S1 invalidation, always use CMDQ_OP_TLBI_NH_VA independently on host ARM_SMMU_FEAT_E2H support (Zenghui) - remove iommu/smmuv3: Accept configs with more than one context descriptor - Remove spurious arm_smmu_cmdq_issue_sync in IOMMU_INV_GRANU_ADDR cache invalidation (Zenghui) - dma-iommu.c changes induced by Zenghui's comments including the locking rework - fix cache invalidation when guest uses RIL and host does not support it (Chenxiang) - removed iommu/smmuv3: Accept configs with more than one context descriptor (Zenghui, Shameer) - At this point I have kept the MSI binding API. v13 -> v14: - Took into account all received comments I think. Great thanks to all the testers for their effort and sometimes tentative fixes. I am really grateful to you! - numerous fixes including guest running in noiommu, iommu.strict=0, iommu.passthrough=on, enable_unsafe_noiommu_mode v12 -> v13: - fixed compilation issue with CONFIG_ARM_SMMU_V3_SVA reported by Shameer. This urged me to revisit patch 4 into iommu/smmuv3: Allow s1 and s2 configs to coexist where s1_cfg and s2_cfg are not dynamically allocated anymore. Instead I use a new set field in existing structs - fixed 2 others config checks - Updated "iommu/arm-smmu-v3: Maintain a SID->device structure" according to the last version v11 -> v12: - rebase on top of v5.10-rc4 Eric Auger (12): iommu: Introduce attach/detach_pasid_table API iommu: Introduce bind/unbind_guest_msi iommu/smmuv3: Allow s1 and s2 configs to coexist iommu/smmuv3: Get prepared for nested stage support iommu/smmuv3: Implement attach/detach_pasid_table iommu/smmuv3: Allow stage 1 invalidation with unmanaged ASIDs iommu/smmuv3: Implement cache_invalidate dma-iommu: Implement NESTED_MSI cookie iommu/smmuv3: Nested mode single MSI doorbell per domain enforcement iommu/smmuv3: Enforce incompatibility between nested mode and HW MSI regions iommu/smmuv3: Implement bind/unbind_guest_msi iommu/smmuv3: report additional recoverable faults drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c | 463 ++++++++++++++++++-- drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.h | 14 +- drivers/iommu/dma-iommu.c | 180 +++++++- drivers/iommu/iommu.c | 106 +++++ include/linux/dma-iommu.h | 16 + include/linux/iommu.h | 47 ++ include/uapi/linux/iommu.h | 54 +++ 7 files changed, 838 insertions(+), 42 deletions(-) -- 2.26.3 _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
