Merge tag 'iommu-updates-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linuxPull iommu updates from Joerg Roedel: - Introduction of the generic IO page-table framework with support for Intel and AMD IOMMU formats from Jason. This has good potential for unifying more IO page-table implementations and making future enhancements more easy. But this also needed quite some fixes during development. All known issues have been fixed, but my feeling is that there is a higher potential than usual that more might be needed. - Intel VT-d updates: - Use right invalidation hint in qi_desc_iotlb() - Reduce the scope of INTEL_IOMMU_FLOPPY_WA - ARM-SMMU updates: - Qualcomm device-tree binding updates for Kaanapali and Glymur SoCs and a new clock for the TBU. - Fix error handling if level 1 CD table allocation fails. - Permit more than the architectural maximum number of SMRs for funky Qualcomm mis-implementations of SMMUv2. - Mediatek driver: - MT8189 iommu support - Move ARM IO-pgtable selftests to kunit - Device leak fixes for a couple of drivers - Random smaller fixes and improvements* tag 'iommu-updates-v6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/iommu/linux: (81 commits) iommupt/vtd: Support mgaw's less than a 4 level walk for first stage iommupt/vtd: Allow VT-d to have a larger table top than the vasz requires powerpc/pseries/svm: Make mem_encrypt.h self contained genpt: Make GENERIC_PT invisible iommupt: Avoid a compiler bug with sw_bit iommu/arm-smmu-qcom: Enable use of all SMR groups when running bare-metal iommupt: Fix unlikely flows in increase_top() iommu/amd: Propagate the error code returned by __modify_irte_ga() in modify_irte_ga() MAINTAINERS: Update my email address iommu/arm-smmu-v3: Fix error check in arm_smmu_alloc_cd_tables dt-bindings: iommu: qcom_iommu: Allow 'tbu' clock iommu/vt-d: Restore previous domain::aperture_end calculation iommu/vt-d: Fix unused invalidation hint in qi_desc_iotlb iommu/vt-d: Set INTEL_IOMMU_FLOPPY_WA depend on BLK_DEV_FD iommu/tegra: fix device leak on probe_device() iommu/sun50i: fix device leak on of_xlate() iommu/omap: simplify probe_device() error handling iommu/omap: fix device leaks on probe_device() iommu/mediatek-v1: add missing larb count sanity check iommu/mediatek-v1: fix device leaks on probe() ...

789a5913b29c2558a4a80b8740a2523f75285507 - iommu/amd: Use the generic iommu page table

Tue, 04 Nov 2025 19:30:11 +0100

iommu/amd: Use the generic iommu page tableReplace the io_pgtable versions with pt_iommu versions. The v2 page tableuses the x86 implementation that will be eventually shared with VT-d.This supports the same special features as the original code: - increase_top for the v1 format to allow scaling from 3 to 6 levels - non-present flushing - Dirty tracking for v1 only - __sme_set() to adjust the PTEs for CC - Optimization for flushing with virtualization to minimize the range - amd_iommu_pgsize_bitmap override of the native page sizes - page tables allocate from the device's NUMA nodeRework the domain ops so that v1/v2 get their own ops. Make dedicatedallocation functions for v1 and v2. Hook up invalidation for a top changeto struct pt_iommu_flush_ops. Delete some of the iopgtable related codethat becomes unused in this patch. The next patch will delete the rest ofit.This fixes a race bug in AMD's increase_address_space() implementation. Itstores the top level and top pointer in different memory, which preventsother threads from reading a coherent version: increase_address_space() alloc_pte() level = pgtable->mode - 1; pgtable->root = pte; pgtable->mode += 1; pte = &pgtable->root[PM_LEVEL_INDEX(level, address)];The iommupt version is careful to put mode and root under a singleREAD_ONCE and then is careful to only READ_ONCE a single time perwalk.Signed-off-by: Alejandro Jimenez Reviewed-by: Vasant Hegde Tested-by: Alejandro Jimenez Tested-by: Pasha Tatashin Signed-off-by: Jason Gunthorpe Signed-off-by: Joerg Roedel List of files: /linux/drivers/iommu/amd/Kconfig
