Merge tag 'iommu-updates-v5.20-or-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel: - The most intrusive patch is small and changes the default allocation policy for DMA addresses. Before the change the allocator tried its best to find an address in the first 4GB. But that lead to performance problems when that space gets exhaused, and since most devices are capable of 64-bit DMA these days, we changed it to search in the full DMA-mask range from the beginning. This change has the potential to uncover bugs elsewhere, in the kernel or the hardware. There is a Kconfig option and a command line option to restore the old behavior, but none of them is enabled by default. - Add Robin Murphy as reviewer of IOMMU code and maintainer for the dma-iommu and iova code - Chaning IOVA magazine size from 1032 to 1024 bytes to save memory - Some core code cleanups and dead-code removal - Support for ACPI IORT RMR node - Support for multiple PCI domains in the AMD-Vi driver - ARM SMMU changes from Will Deacon: - Add even more Qualcomm device-tree compatible strings - Support dumping of IMP DEF Qualcomm registers on TLB sync timeout - Fix reference count leak on device tree node in Qualcomm driver - Intel VT-d driver updates from Lu Baolu: - Make intel-iommu.h private - Optimize the use of two locks - Extend the driver to support large-scale platforms - Cleanup some dead code - MediaTek IOMMU refactoring and support for TTBR up to 35bit - Basic support for Exynos SysMMU v7 - VirtIO IOMMU driver gets a map/unmap_pages() implementation - Other smaller cleanups and fixes * tag 'iommu-updates-v5.20-or-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (116 commits) iommu/amd: Fix compile warning in init code iommu/amd: Add support for AVIC when SNP is enabled iommu/amd: Simplify and Consolidate Virtual APIC (AVIC) Enablement ACPI/IORT: Fix build error implicit-function-declaration drivers: iommu: fix clang -wformat warning iommu/arm-smmu: qcom_iommu: Add of_node_put() when breaking out of loop iommu/arm-smmu-qcom: Add SM6375 SMMU compatible dt-bindings: arm-smmu: Add compatible for Qualcomm SM6375 MAINTAINERS: Add Robin Murphy as IOMMU SUBSYTEM reviewer iommu/amd: Do not support IOMMUv2 APIs when SNP is enabled iommu/amd: Do not support IOMMU_DOMAIN_IDENTITY after SNP is enabled iommu/amd: Set translation valid bit only when IO page tables are in use iommu/amd: Introduce function to check and enable SNP iommu/amd: Globally detect SNP support iommu/amd: Process all IVHDs before enabling IOMMU features iommu/amd: Introduce global variable for storing common EFR and EFR2 iommu/amd: Introduce Support for Extended Feature 2 Register iommu/amd: Change macro for IOMMU control register bit shift to decimal value iommu/exynos: Enable default VM instance on SysMMU v7 iommu/exynos: Add SysMMU v7 register set ...
