The summary is in the tag, but the highlight is definitely the removal of the complicated block-splitting code from the Arm page-table implementations. It even means that we have a negative diffstat! As with 6.12, I've already pushed this lot to the arm/smmu branch in the iommu tree. Please can you merge that into 'next'? Cheers, Will --->8 The following changes since commit 8e929cb546ee42c9a61d24fae60605e9e3192354: Linux 6.12-rc3 (2024-10-13 14:33:32 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git tags/arm-smmu-updates for you to fetch changes up to a3799717b881aa0f4e722afb70e7b8ba84ae4f36: iommu/tegra241-cmdqv: Fix alignment failure at max_n_shift (2024-11-12 15:09:42 +0000) ---------------------------------------------------------------- Arm SMMU updates for 6.13 - SMMUv2: * Return -EPROBE_DEFER for client devices probing before their SMMU. * Devicetree binding updates for Qualcomm MMU-500 implementations. - SMMUv3: * Minor fixes and cleanup for NVIDIA's virtual command queue driver. - IO-PGTable: * Fix indexing of concatenated PGDs and extend selftest coverage. * Remove unused block-splitting support. ---------------------------------------------------------------- Dmitry Baryshkov (1): dt-bindings: iommu: arm,smmu: Add Qualcomm SAR2130P compatible Jason Gunthorpe (3): iommu/io-pgtable-arm: Remove split on unmap behavior iommu/io-pgtable-arm-v7s: Remove split on unmap behavior iommu: Add a kdoc to iommu_unmap() Mostafa Saleh (2): iommu/io-pgtable-arm: Fix stage-2 map/unmap for concatenated tables iommu/io-pgtable-arm: Add self test for the last page in the IAS Nicolin Chen (2): iommu/tegra241-cmdqv: Staticize cmdqv_debugfs_dir iommu/tegra241-cmdqv: Fix alignment failure at max_n_shift Pratyush Brahma (1): iommu/arm-smmu: Defer probe of clients after smmu device bound Qingqing Zhou (1): dt-bindings: arm-smmu: document QCS615 APPS SMMU Will Deacon (2): iommu/tegra241-cmdqv: Fix unused variable warning Merge branch 'for-joerg/arm-smmu/bindings' into arm/smmu .../devicetree/bindings/iommu/arm,smmu.yaml | 5 + drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c | 7 +- drivers/iommu/arm/arm-smmu/arm-smmu.c | 11 ++ drivers/iommu/io-pgtable-arm-v7s.c | 149 +-------------------- drivers/iommu/io-pgtable-arm.c | 114 +++++----------- drivers/iommu/iommu.c | 14 ++ 6 files changed, 74 insertions(+), 226 deletions(-)
