This creates the iommufd_device for the physical VFIO drivers. These are all the drivers that are calling vfio_register_group_dev() and expect the type1 code to setup a real iommu_domain against their parent struct device. The design gives the driver a choice in how it gets connected to iommufd by providing bind_iommufd/unbind_iommufd/attach_ioas callbacks to implement as required. The core code provides three default callbacks for physical mode using a real iommu_domain. This is suitable for drivers using vfio_register_group_dev() Link: https://lore.kernel.org/r/6-v4-42cd2eb0e3eb+335a-vfio_iommufd_jgg@nvidia.com Reviewed-by: Kevin Tian <kevin.tian@intel.com> Reviewed-by: Alex Williamson <alex.williamson@redhat.com> Tested-by: Alex Williamson <alex.williamson@redhat.com> Tested-by: Nicolin Chen <nicolinc@nvidia.com> Tested-by: Yi Liu <yi.l.liu@intel.com> Tested-by: Lixiao Yang <lixiao.yang@intel.com> Tested-by: Matthew Rosato <mjrosato@linux.ibm.com> Tested-by: Yu He <yu.he@intel.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
