Merge tag 'iommu-updates-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel: "A big part of this is a change in how devices get connected to IOMMUs in the core code. It contains the change from the old add_device() / remove_device() to the new probe_device() / release_device() call-backs. As a result functionality that was previously in the IOMMU drivers has been moved to the IOMMU core code, including IOMMU group allocation for each device. The reason for this change was to get more robust allocation of default domains for the iommu groups. A couple of fixes were necessary after this was merged into the IOMMU tree, but there are no known bugs left. The last fix is applied on-top of the merge commit for the topic branches. Other than that change, we have: - Removal of the driver private domain handling in the Intel VT-d driver. This was fragile code and I am glad it is gone now. - More Intel VT-d updates from Lu Baolu: - Nested Shared Virtual Addressing (SVA) support to the Intel VT-d driver - Replacement of the Intel SVM interfaces to the common IOMMU SVA API - SVA Page Request draining support - ARM-SMMU Updates from Will: - Avoid mapping reserved MMIO space on SMMUv3, so that it can be claimed by the PMU driver - Use xarray to manage ASIDs on SMMUv3 - Reword confusing shutdown message - DT compatible string updates - Allow implementations to override the default domain type - A new IOMMU driver for the Allwinner Sun50i platform - Support for ATS gets disabled for untrusted devices (like Thunderbolt devices). This includes a PCI patch, acked by Bjorn. - Some cleanups to the AMD IOMMU driver to make more use of IOMMU core features. - Unification of some printk formats in the Intel and AMD IOMMU drivers and in the IOVA code. - Updates for DT bindings - A number of smaller fixes and cleanups. * tag 'iommu-updates-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (109 commits) iommu: Check for deferred attach in iommu_group_do_dma_attach() iommu/amd: Remove redundant devid checks iommu/amd: Store dev_data as device iommu private data iommu/amd: Merge private header files iommu/amd: Remove PD_DMA_OPS_MASK iommu/amd: Consolidate domain allocation/freeing iommu/amd: Free page-table in protection_domain_free() iommu/amd: Allocate page-table in protection_domain_init() iommu/amd: Let free_pagetable() not rely on domain->pt_root iommu/amd: Unexport get_dev_data() iommu/vt-d: Fix compile warning iommu/vt-d: Remove real DMA lookup in find_domain iommu/vt-d: Allocate domain info for real DMA sub-devices iommu/vt-d: Only clear real DMA device's context entries iommu: Remove iommu_sva_ops::mm_exit() uacce: Remove mm_exit() op iommu/sun50i: Constify sun50i_iommu_ops iommu/hyper-v: Constify hyperv_ir_domain_ops iommu/vt-d: Use pci_ats_supported() iommu/arm-smmu-v3: Use pci_ats_supported() ...
