[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v1 21/25] xen/domctl: wrap aound iommu-related domctl op
Function iommu_do_domctl() is the main entry for all iommu-related domctl-op.
Tracking its calling chaining, the following functions shall all be wrapped:
- iommu_do_pci_domctl
- xsm_get_device_group
- iommu_get_device_group
- amd_iommu_group_id/intel_iommu_group_id
- xsm_assign_device
- device_assigned
- assign_device
- intel_iommu_assign_device/amd_iommu_assign_devic
- xsm_deassign_device
- deassign_device
- reassign_device_ownership/reassign_device
- iommu_do_dt_domctl
- xsm_assign_dtdevice
- xsm_deassign_dtdevice
- iommu_deassign_dt_device
- arm_smmu_reassign_dev/arm_smmu_reassign_dev
- ipmmu_reassign_dev
- ipmmu_deassign_dev
- ipmmu_detach_dev
- dt_find_node_by_gpath
