Eric Auger made a huge effort previously with the VFIO uAPIs, and sent his v16 a year ago. Now, the nested translation should follow the new IOMMUFD uAPIs design. So, most of the key features are ported from the privous VFIO solution, and then rebuilt on top of the IOMMUFD nesting infrastructure. This series is rebased on top of the Intel VT-d nesting changes, so as to reduce merge conflicts at the uapi header updates. The essential parts in the driver to support a nested translation are ->hw_info, ->domain_alloc_user and ->invalidate_cache_user ops. So this series fundamentally adds these three functions in the SMMUv3 driver, along with several preparations and cleanups for them. One unique requirement for SMMUv3 nested translation support is the MSI doorbell address translation, which is a 2-stage translation too. And, to working with the ITS driver, an msi_cookie needs to be setup on the kernel-managed domain, the stage-2 domain of the nesting setup. And the same msi_cookie will be fetched, via iommu_get_domain_for_dev(), in the iommu core to allocate and creates IOVA mappings for the MSI doorbell page(s). However, with the nesting design, the device is attached to a user-managed domain, the stage-1 domain. So both the setup and fetching of the msi_cookie would not work at the level of stage-2 domain. Thus, on both sides, the msi_cookie setup and fetching require a redirection of the domain pointer. It's easy to do so in iommufd core, but needs a new op in the iommu core and driver. You can also find this series on the Github: https://github.com/nicolinc/iommufd/commits/iommufd_nesting The kernel branch is tested with this QEMU branch: https://github.com/nicolinc/qemu/commits/wip/iommufd_rfcv3+nesting+smmuv3 Thanks!
