Merge tag 'iommu-updates-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel: "Core: - IOMMU memory usage observability - This will make the memory used for IO page tables explicitly visible. - Simplify arch_setup_dma_ops() Intel VT-d: - Consolidate domain cache invalidation - Remove private data from page fault message - Allocate DMAR fault interrupts locally - Cleanup and refactoring ARM-SMMUv2: - Support for fault debugging hardware on Qualcomm implementations - Re-land support for the ->domain_alloc_paging() callback ARM-SMMUv3: - Improve handling of MSI allocation failure - Drop support for the "disable_bypass" cmdline option - Major rework of the CD creation code, following on directly from the STE rework merged last time around. - Add unit tests for the new STE/CD manipulation logic AMD-Vi: - Final part of SVA changes with generic IO page fault handling Renesas IPMMU: - Add support for R8A779H0 hardware ... and a couple smaller fixes and updates across the sub-tree" * tag 'iommu-updates-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (80 commits) iommu/arm-smmu-v3: Make the kunit into a module arm64: Properly clean up iommu-dma remnants iommu/amd: Enable Guest Translation after reading IOMMU feature register iommu/vt-d: Decouple igfx_off from graphic identity mapping iommu/amd: Fix compilation error iommu/arm-smmu-v3: Add unit tests for arm_smmu_write_entry iommu/arm-smmu-v3: Build the whole CD in arm_smmu_make_s1_cd() iommu/arm-smmu-v3: Move the CD generation for SVA into a function iommu/arm-smmu-v3: Allocate the CD table entry in advance iommu/arm-smmu-v3: Make arm_smmu_alloc_cd_ptr() iommu/arm-smmu-v3: Consolidate clearing a CD table entry iommu/arm-smmu-v3: Move the CD generation for S1 domains into a function iommu/arm-smmu-v3: Make CD programming use arm_smmu_write_entry() iommu/arm-smmu-v3: Add an ops indirection to the STE code iommu/arm-smmu-qcom: Don't build debug features as a kernel module iommu/amd: Add SVA domain support iommu: Add ops->domain_alloc_sva() iommu/amd: Initial SVA support for AMD IOMMU iommu/amd: Add support for enable/disable IOPF iommu/amd: Add IO page fault notifier handler ...
