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) #
