Merge tag 'iommu-updates-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel: - New DART IOMMU driver for Apple Silicon M1 chips - Optimizations for iommu_[map/unmap] performance - Selective TLB flush support for the AMD IOMMU driver to make it more efficient on emulated IOMMUs - Rework IOVA setup and default domain type setting to move more code out of IOMMU drivers and to support runtime switching between certain types of default domains - VT-d Updates from Lu Baolu: - Update the virtual command related registers - Enable Intel IOMMU scalable mode by default - Preset A/D bits for user space DMA usage - Allow devices to have more than 32 outstanding PRs - Various cleanups - ARM SMMU Updates from Will Deacon: SMMUv3: - Minor optimisation to avoid zeroing struct members on CMD submission - Increased use of batched commands to reduce submission latency - Refactoring in preparation for ECMDQ support SMMUv2: - Fix races when probing devices with identical StreamIDs - Optimise walk cache flushing for Qualcomm implementations - Allow deep sleep states for some Qualcomm SoCs with shared clocks - Various smaller optimizations, cleanups, and fixes * tag 'iommu-updates-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (85 commits) iommu/io-pgtable: Abstract iommu_iotlb_gather access iommu/arm-smmu: Fix missing unlock on error in arm_smmu_device_group() iommu/vt-d: Add present bit check in pasid entry setup helpers iommu/vt-d: Use pasid_pte_is_present() helper function iommu/vt-d: Drop the kernel doc annotation iommu/vt-d: Allow devices to have more than 32 outstanding PRs iommu/vt-d: Preset A/D bits for user space DMA usage iommu/vt-d: Enable Intel IOMMU scalable mode by default iommu/vt-d: Refactor Kconfig a bit iommu/vt-d: Remove unnecessary oom message iommu/vt-d: Update the virtual command related registers iommu: Allow enabling non-strict mode dynamically iommu: Merge strictness and domain type configs iommu: Only log strictness for DMA domains iommu: Expose DMA domain strictness via sysfs iommu: Express DMA strictness via the domain type iommu/vt-d: Prepare for multiple DMA domain types iommu/arm-smmu: Prepare for multiple DMA domain types iommu/amd: Prepare for multiple DMA domain types iommu: Introduce explicit type for non-strict DMA domains ...
