Hi all, This patch set removes unused VT-d virtual command interface followed by removal of the IOASID infrastructure. This has only been tested on x86 platforms, need help with testing on ARM SMMU and other architectures. Thanks, Jacob ChangeLog: v7: - use CONFIG_IOMMU_SVA around PASID helpers in fork.c, Fixes a compile problem. - Fix extra space 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 | 61 ++--- 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 | 5 + mm/init-mm.c | 4 +- 21 files changed, 54 insertions(+), 693 deletions(-) delete mode 100644 drivers/iommu/ioasid.c delete mode 100644 include/linux/ioasid.h -- 2.25.1
