Emulated VFIO devices are calling vfio_register_emulated_iommu_dev() and consist of all the mdev drivers. Like the physical drivers, support for iommufd is provided by the driver supplying the correct standard ops. Provide ops from the core that duplicate what vfio_register_emulated_iommu_dev() does. Emulated drivers are where it is more likely to see variation in the iommfd support ops. For instance IDXD will probably need to setup both a iommfd_device context linked to a PASID and an iommufd_access context to support all their mdev operations.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
