Hi Alex, I've got a cdev v7 candidate in below branch. It has three sub-series per the suggestion in prior cdev review. - cover-letter: Add vfio_device cdev for iommufd support - cover-letter: Introduce new methods for verifying ownership in vfio PCI hot reset - cover-letter: vfio: Make emulated devices prepared for vfio device cdev https://github.com/yiliu1765/iommufd/tree/wip/vfio_device_cdev_v7_candidate However, there is one open on Nicolin's patch in below link. So I need to wait for it before sending v7. https://lore.kernel.org/kvm/ZBGJzefTm4p%2FReIu@Asurada-Nvidia/ Regards, Yi Liu
