The Allwinner H6 has introduced an IOMMU for a few DMA controllers, mostly video related: the display engine, the video decoders / encoders, the camera capture controller, etc. The design is pretty simple compared to other IOMMUs found in SoCs: there's a single instance, controlling all the masters, with a single address space. It also features a performance monitoring unit that allows to retrieve various informations (per-master and global TLB accesses, hits and misses, access latency, etc) that isn't supported at the moment.

README
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.
