ADMA2 64-bit addressing support is divided into V3 mode and V4 mode. So there are two kinds of descriptors for ADMA2 64-bit addressing i.e. 96-bit Descriptor for V3 mode, and 128-bit Descriptor for V4 mode. 128-bit Descriptor is aligned to 8-byte. For V4 mode, ADMA2 64-bit addressing is enabled via Host Control 2 register.

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.
