At the moment we only support in the host the IOMMU page sizes which the guest is aware of, which is 4KB/64KB/16MB. However P9 does not support 16MB IOMMU pages, 2MB and 1GB pages are supported instead. We can still emulate bigger guest pages (for example 16MB) with smaller host pages (4KB/64KB/2MB). This allows the physical IOMMU pages to use a page size smaller or equal than the guest visible IOMMU page size.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
