Hi Joerg, Please pull these Arm SMMU updates for v6.12. The big new feature is support for NVIDIA's virtual command queue implementation for SMMUv3, but everything is summarised in the tag. ** Please note **: I've already pushed this to the arm/smmu branch for -next coverage, but I thought sending a pull request was still useful for the records and the signed tag. If you want to recreate the branch, please feel free. See you at LPC! Cheers, Will --->8 The following changes since commit 7c626ce4bae1ac14f60076d00eafe71af30450ba: Linux 6.11-rc3 (2024-08-11 14:27:14 -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 f1c6cf8e7ab9d7498ee70c69d5093165952d3595: Merge branch 'for-joerg/arm-smmu/bindings' into for-joerg/arm-smmu/updates (2024-09-12 12:54:14 +0100) ---------------------------------------------------------------- Arm SMMU updates for 6.12 - SMMUv2: * Devicetree binding updates for Qualcomm MMU-500 implementations. * Extend workarounds for broken Qualcomm hypervisor to avoid touching features that are not available (e.g. 16KiB page support, reserved context banks). - SMMUv3: * Support for NVIDIA's custom virtual command queue hardware. * Fix Stage-2 stall configuration and extend tests to cover this area. * A bunch of driver cleanups, including simplification of the master rbtree code. - Plus minor cleanups and fixes across both drivers. ---------------------------------------------------------------- Dan Carpenter (2): iommu/arm-smmu-v3: Fix a NULL vs IS_ERR() check iommu/tegra241-cmdqv: Fix ioremap() error handling in probe() Dmitry Baryshkov (1): iommu/arm-smmu-qcom: apply num_context_bank fixes for SDM630 / SDM660 Jason Gunthorpe (10): iommu/arm-smmu-v3: Add struct arm_smmu_impl_ops iommu/arm-smmu-v3: Use the new rb tree helpers iommu/arm-smmu-v3: Add arm_smmu_strtab_l1/2_idx() iommu/arm-smmu-v3: Add types for each level of the 2 level stream table iommu/arm-smmu-v3: Reorganize struct arm_smmu_strtab_cfg iommu/arm-smmu-v3: Remove strtab_base/cfg iommu/arm-smmu-v3: Do not use devm for the cd table allocations iommu/arm-smmu-v3: Shrink the cdtab l1_desc array iommu/arm-smmu-v3: Add types for each level of the CD table iommu/arm-smmu-v3: Reorganize struct arm_smmu_ctx_desc_cfg Konrad Dybcio (1): iommu/arm-smmu-qcom: Work around SDM845 Adreno SMMU w/ 16K pages Marc Gonzalez (1): iommu/arm-smmu-qcom: hide last LPASS SMMU context bank from linux Mostafa Saleh (2): iommu/arm-smmu-v3: Match Stall behaviour for S2 iommu/arm-smmu-v3-test: Test masters with stall enabled Nate Watterson (1): iommu/arm-smmu-v3: Add in-kernel support for NVIDIA Tegra241 (Grace) CMDQV Nicolin Chen (11): iommu/arm-smmu-v3: Issue a batch of commands to the same cmdq iommu/arm-smmu-v3: Pass in cmdq pointer to arm_smmu_cmdq_build_sync_cmd iommu/arm-smmu-v3: Pass in cmdq pointer to arm_smmu_cmdq_init iommu/arm-smmu-v3: Make symbols public for CONFIG_TEGRA241_CMDQV iommu/arm-smmu-v3: Add ARM_SMMU_OPT_TEGRA241_CMDQV iommu/arm-smmu-v3: Add acpi_smmu_iort_probe_model for impl iommu/arm-smmu-v3: Start a new batch if new command is not supported iommu/tegra241-cmdqv: Limit CMDs for VCMDQs of a guest owned VINTF iommu/tegra241-cmdqv: Fix -Wformat-truncation warnings in lvcmdq_error_header iommu/tegra241-cmdqv: Drop static at local variable iommu/tegra241-cmdqv: Do not allocate vcmdq until dma_set_mask_and_coherent Nikunj Kela (1): dt-bindings: arm-smmu: document the support on SA8255p Rob Clark (1): iommu/arm-smmu: Un-demote unhandled-fault msg Will Deacon (1): Merge branch 'for-joerg/arm-smmu/bindings' into for-joerg/arm-smmu/updates Zhang Zekun (1): iommu/arm-smmu-v3: Remove the unused empty definition Zhenhua Huang (1): dt-bindings: arm-smmu: Add compatible for QCS8300 SoC .../devicetree/bindings/iommu/arm,smmu.yaml | 5 + MAINTAINERS | 1 + drivers/iommu/Kconfig | 11 + drivers/iommu/arm/arm-smmu-v3/Makefile | 1 + drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3-test.c | 83 +- drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c | 576 +++++++------ drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.h | 137 +++- drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c | 909 +++++++++++++++++++++ drivers/iommu/arm/arm-smmu/arm-smmu-qcom.c | 28 + drivers/iommu/arm/arm-smmu/arm-smmu.c | 2 +- 10 files changed, 1463 insertions(+), 290 deletions(-) create mode 100644 drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c
