[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).

[PATCH 0/3] selftests: Fix virtual address range for arm64

by Chaitanya S Prakash

When the virtual address range selftest is run on arm64 and x86 platforms, it is observed that both the low and high VA range iterations are skipped when the MAP_CHUNK_SIZE is set to 16GB. The MAP_CHUNK_SIZE is changed to 1GB to resolve this issue, following which support for arm64 platform is added by changing the NR_CHUNKS_HIGH for aarch64 to accommodate up to 4PB of virtual address space allocation requests. Dynamic memory allocation of array holding addresses is introduced to prevent overflow of the stack. Finally, the overcommit_policy is set as OVERCOMMIT_ALWAYS to prevent the kernel from denying a memory allocation request based on a platform's physical memory availability. This series has been tested on 6.3.0-rc1 mainline kernel, both on arm64 and x86 platforms.
