This has only been tested on x86 platforms, need help with testing on ARM SMMU and other architectures. Thanks, Jacob ChangeLog: v6: - put pasid helpers under iommu.h instead of iommu-helper.h - add comments for pasid allocation function to clarify inclusive range v5: - rebased on v6.3-rc1 - put removing iommu_sva_find() in a separate patch (Kevin) - move definition of helpers to iommu code to be consistent with declarations. (Kevin) - misc fixes v4: - keep mm_pasid helpers inline as much as we can for fork performance - separate GFP_ATOMIC to GFP_KERNEL change for bisectability v3: - moved helper functions for PASID under SVA code, avoided circular inclusion between mm.h and iommu.h - deleted makefiles - put rename under a different patch Jacob Pan (5): iommu/vt-d: Remove virtual command interface iommu/sva: Move PASID helpers to sva code iommu/sva: Remove PASID to mm lookup function iommu/sva: Use GFP_KERNEL for pasid allocation iommu/ioasid: Rename INVALID_IOASID Jason Gunthorpe (2): iommu/sva: Stop using ioasid_set for SVA iommu: Remove ioasid infrastructure Documentation/x86/sva.rst | 2 +- arch/x86/kernel/traps.c | 5 +- drivers/dma/idxd/device.c | 8 +- drivers/dma/idxd/idxd.h | 2 +- drivers/dma/idxd/init.c | 2 +- drivers/dma/idxd/irq.c | 2 +- drivers/iommu/Kconfig | 5 - drivers/iommu/Makefile | 1 - drivers/iommu/intel/cap_audit.c | 2 - drivers/iommu/intel/dmar.c | 6 +- drivers/iommu/intel/iommu.c | 87 +------ drivers/iommu/intel/iommu.h | 3 - drivers/iommu/intel/svm.c | 3 +- drivers/iommu/ioasid.c | 422 -------------------------------- drivers/iommu/iommu-sva.c | 63 ++--- drivers/iommu/iommu-sva.h | 4 - include/linux/ioasid.h | 83 ------- include/linux/iommu.h | 14 +- include/linux/sched/mm.h | 26 -- kernel/fork.c | 3 + mm/init-mm.c | 4 +- 21 files changed, 53 insertions(+), 694 deletions(-) delete mode 100644 drivers/iommu/ioasid.c delete mode 100644 include/linux/ioasid.h -- 2.25.1
