kunit.py currently crashes and fails to parse kernel output if it's not
fully valid utf-8.
This can come from memory corruption or just inadvertently printing
out binary data as strings.
E.g. adding this line into a kunit test
pr_info("\x80")
will cause this exception
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position
1961: invalid start byte
We can tell Python how to handle errors, see
https://docs.python.org/3/library/codecs.html#error-handlers
Unfortunately, it doesn't seem like there's a way to specify this in
just one location, so we need to repeat ourselves quite a bit.
Specify `errors='backslashreplace'` so we instead:
* print out the offending byte as '\x80'
* try and continue parsing the output.
* as long as the TAP lines themselves are valid, we're fine.

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.
