As well as the default domain type, it's useful to know whether strict or lazy for DMA domains, so add this info in a separate print. The (stict/lazy) mode may be also set via iommu.strict earlyparm, but this will be processed prior to iommu_subsys_init(), so that print will be accurate for drivers which don't set the mode via custom means. For the drivers which set the mode via custom means - AMD and Intel drivers - they maintain prints to inform a change in policy or that custom cmdline methods to change policy are deprecated.

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.
