This update introduces new features, quick fixes and several refactorings, including: - Consolidation of complex enablement logic into a clean, priority-based state machine. - Support for the DMA_REMAP_OPT_OUT flag from the VT-d v5.2 specification. - An update to cache_tag_flush_devtlb_psi() to use full-range constants instead of modifying shared variables for CACHE_TAG_NESTING_DEVTLB. - A fix for the UCTP context-table slot when copying root entries. - Fixes for several pre-existing issues reported by Sashiko. - General code cleanup and refinement. These patches are based on v7.2-rc6. The full series is also available on GitHub: https://github.com/LuBaolu/intel-iommu/commits/iommu/vt-d/next Please consider pulling this series into the iommu/vt-d branch. Change log: v2: - Sashiko reported a critical issue in the previous PATCH 16/20. Remove that patch from this series. It requires more investigation time and will be submitted as a separate patch. - Add comments to the commit message of PATCH 03/20. v1: https://lore.kernel.org/linux-iommu/20260804023714.3080506-1-baolu.lu@linux.intel.com/ Best regards, baolu Desnes Nunes (1): iommu/vt-d: Fix UCTP context table slot when copying root entries Dmitry Antipov (1): iommu/vt-d: Use kstrtoint_from_user() in dmar_perf_latency_write() Guanghui Feng (1): iommu/vt-d: Fix CACHE_TAG_NESTING_DEVTLB polluting shared variables in flush loop Kevin Tian (9): iommu/vt-d: Fix no_iommu to disable platform opt-in iommu/vt-d: Force requesting ACS when tboot is enabled iommu/vt-d: Remove dead code when CONFIG_INTEL_IOMMU is not set iommu/vt-d: Consolidate dmar policy management and force_on logic iommu/vt-d: Use dmar_can_force_on() for platform opt-in iommu/vt-d: Call dmar_can_force_on() for tboot opt-in iommu/vt-d: Remove the 'force_on' variable iommu/vt-d: Remove dmar_disabled iommu/vt-d: Support the new DMA_REMAP_OPT_OUT flag bit Li RongQing (1): iommu/vt-d: Use logical OR operator for privilege mode check Lu Baolu (5): iommu/vt-d: Cache max domain ID to avoid redundant calculation iommu/vt-d: Clear Present bit before tearing down copied context entry iommu/vt-d: Fix iopf_refcount leak on RID domain replacement iommu/vt-d: Tear down scalable-mode context on probe failure iommu/vt-d: Flush context cache with correct SID when tearing down aliases ZhaoJinming (1): iommu/vt-d: Fix copied_tables bitmap leak on error in copy_translation_tables drivers/iommu/intel/iommu.h | 73 ++++++++++++++---- include/linux/dmar.h | 1 + drivers/iommu/intel/cache.c | 5 +- drivers/iommu/intel/debugfs.c | 16 +--- drivers/iommu/intel/dmar.c | 96 ++++++++++++++++++++--- drivers/iommu/intel/iommu.c | 139 +++++++++++++++++++--------------- drivers/iommu/intel/pasid.c | 9 ++- drivers/iommu/intel/prq.c | 2 +- drivers/iommu/intel/svm.c | 2 +- 9 files changed, 238 insertions(+), 105 deletions(-) -- 2.43.0
