According to LoPAR, ibm,query-pe-dma-window output named "IO Page Sizes" will let the OS know all possible pagesizes that can be used for creating a new DDW. Currently Linux will only try using 3 of the 8 available options: 4K, 64K and 16M. According to LoPAR, Hypervisor may also offer 32M, 64M, 128M, 256M and 16G. Enabling bigger pages would be interesting for direct mapping systems with a lot of RAM, while using less TCE entries.

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.
