The VFIO part is submitted separately. 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: https://github.com/eauger/linux/tree/5.10-rc4-2stage-v13 (including the VFIO part in his last version: v11) The series includes a patch from Jean-Philippe. It is better to review the original patch: [PATCH v8 2/9] iommu/arm-smmu-v3: Maintain a SID->device structure The VFIO series is sent separately. History: 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 (14): 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 non recoverable faults iommu/smmuv3: Accept configs with more than one context descriptor iommu/smmuv3: Add PASID cache invalidation per PASID Jean-Philippe Brucker (1): iommu/arm-smmu-v3: Maintain a SID->device structure drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c | 659 ++++++++++++++++++-- drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.h | 103 ++- drivers/iommu/dma-iommu.c | 142 ++++- drivers/iommu/iommu.c | 105 ++++ include/linux/dma-iommu.h | 16 + include/linux/iommu.h | 41 ++ include/uapi/linux/iommu.h | 54 ++ 7 files changed, 1042 insertions(+), 78 deletions(-) -- 2.21.3 _______________________________________________ kvmarm mailing list kvmarm@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
