Quote from the virtio specification chapter 4.2.2.2:
"For the device-specific configuration space, the driver MUST use 8 bit
wide accesses for 8 bit wide fields, 16 bit wide and aligned accesses
for 16 bit wide fields and 32 bit wide and aligned accesses for 32 and
64 bit wide fields."

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 reStructuredText 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.
