[PATCH v2 0/5] Add Intel VT-d nested translation

by Yi Liu

This is to add Intel VT-d nested translation based on IOMMUFD nesting infrastructure. As the iommufd nesting infrastructure series[1], iommu core supports new ops to report iommu hardware information, allocate domains with user data and sync stage-1 IOTLB. The data required in the three paths are vendor-specific, so 1) IOMMU_HW_INFO_TYPE_INTEL_VTD and struct iommu_device_info_vtd are defined to report iommu hardware information for Intel VT-d . 2) IOMMU_HWPT_DATA_VTD_S1 is defined for the Intel VT-d stage-1 page table, it will be used in the stage-1 domain allocation and IOTLB syncing path. struct iommu_hwpt_intel_vtd is defined to pass user_data for the Intel VT-d stage-1 domain allocation. struct iommu_hwpt_invalidate_intel_vtd is defined to pass the data for the Intel VT-d stage-1 IOTLB invalidation. With above IOMMUFD extensions, the intel iommu driver implements the three callbacks to support nested translation. Complete code can be found in [2], QEMU could can be found in [3]. base-commit: f01f1c95684dd18c15dd0e51b4fd6e796a0a2c0e [1] https://lore.kernel.org/linux-iommu/20230309080910.607396-1-yi.l.liu@intel.… [2] https://github.com/yiliu1765/iommufd/tree/iommufd_nesting [3] https://github.com/yiliu1765/qemu/tree/wip/iommufd_rfcv3%2Bnesting Change log: v2: - The iommufd infrastructure is split to be separate series. v1: https://lore.kernel.org/linux-iommu/20230209043153.14964-1-yi.l.liu@intel.c… Regards, Yi Liu Lu Baolu (4): iommu/vt-d: Implement hw_info for iommu capability query iommu/vt-d: Extend dmar_domain to support nested domain iommu/vt-d: Add helper to setup pasid nested translation iommu/vt-d: Add nested domain support Yi Liu (1): iommufd: Add nesting related data structures for Intel VT-d drivers/iommu/intel/Makefile | 2 +- drivers/iommu/intel/iommu.c | 57 ++++++++--- drivers/iommu/intel/iommu.h | 51 ++++++++-- drivers/iommu/intel/nested.c | 143 +++++++++++++++++++++++++++ drivers/iommu/intel/pasid.c | 142 ++++++++++++++++++++++++++ drivers/iommu/intel/pasid.h | 2 + drivers/iommu/iommufd/hw_pagetable.c | 7 +- drivers/iommu/iommufd/main.c | 5 + include/uapi/linux/iommufd.h | 136 +++++++++++++++++++++++++ 9 files changed, 522 insertions(+), 23 deletions(-) create mode 100644 drivers/iommu/intel/nested.c -- 2.34.1

[PATCH] selftests: sigaltstack: fix -Wuninitialized

by Nick Desaulniers

Building sigaltstack with clang via: $ ARCH=x86 make LLVM=1 -C tools/testing/selftests/sigaltstack/ produces the following warning: warning: variable 'sp' is uninitialized when used here [-Wuninitialized] if (sp < (unsigned long)sstack || ^~ Clang expects these to be declared at global scope; we've fixed this in the kernel proper by using the macro `current_stack_pointer`. This is defined in different headers for different target architectures, so just create a new header that defines the arch-specific register names for the stack pointer register, and define it for more targets (at least the ones that support current_stack_pointer/ARCH_HAS_CURRENT_STACK_POINTER).

selftests: arm64: list of test failures

by Naresh Kamboju

selftests: arm64 below list of test cases fails on Linux next and Linux mainline builds with clang-16 and gcc-12 kernel booted on recently configured tuxrun qemu-arm64 (v7.2) enabled with MTE=on. Am I missing anything on test configs / environment ?
