Merge tag 'iommu-updates-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel: - Consolidate iommu_map/unmap functions. There have been blocking and atomic variants so far, but that was problematic as this approach does not scale with required new variants which just differ in the GFP flags used. So Jason consolidated this back into single functions that take a GFP parameter. - Retire the detach_dev() call-back in iommu_ops - Arm SMMU updates from Will: - Device-tree binding updates: - Cater for three power domains on SM6375 - Document existing compatible strings for Qualcomm SoCs - Tighten up clocks description for platform-specific compatible strings - Enable Qualcomm workarounds for some additional platforms that need them - Intel VT-d updates from Lu Baolu: - Add Intel IOMMU performance monitoring support - Set No Execute Enable bit in PASID table entry - Two performance optimizations - Fix PASID directory pointer coherency - Fix missed rollbacks in error path - Cleanups - Apple t8110 DART support - Exynos IOMMU: - Implement better fault handling - Error handling fixes - Renesas IPMMU: - Add device tree bindings for r8a779g0 - AMD IOMMU: - Various fixes for handling on SNP-enabled systems and handling of faults with unknown request-ids - Cleanups and other small fixes - Various other smaller fixes and cleanups * tag 'iommu-updates-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (71 commits) iommu/amd: Skip attach device domain is same as new domain iommu: Attach device group to old domain in error path iommu/vt-d: Allow to use flush-queue when first level is default iommu/vt-d: Fix PASID directory pointer coherency iommu/vt-d: Avoid superfluous IOTLB tracking in lazy mode iommu/vt-d: Fix error handling in sva enable/disable paths iommu/amd: Improve page fault error reporting iommu/amd: Do not identity map v2 capable device when snp is enabled iommu: Fix error unwind in iommu_group_alloc() iommu/of: mark an unused function as __maybe_unused iommu: dart: DART_T8110_ERROR range should be 0 to 5 iommu/vt-d: Enable IOMMU perfmon support iommu/vt-d: Add IOMMU perfmon overflow handler support iommu/vt-d: Support cpumask for IOMMU perfmon iommu/vt-d: Add IOMMU perfmon support iommu/vt-d: Support Enhanced Command Interface iommu/vt-d: Retrieve IOMMU perfmon capability information iommu/vt-d: Support size of the register set in DRHD iommu/vt-d: Set No Execute Enable bit in PASID table entry iommu/vt-d: Remove sva from intel_svm_dev ...
