When the script detects the need for an upgrade, it will
print either a warning or a note.
Let's change a little bit the order where messages will be
displayed, in order to make easier for the user to identify
the more important messages.
It should now be like this:
Detected OS: Fedora release 31 (Thirty One).
Sphinx version: 1.7.9
Note: It is recommended at least Sphinx version 2.4.4 if you need PDF support.
To upgrade Sphinx, use:
/usr/bin/python3 -m venv sphinx_2.4.4
. sphinx_2.4.4/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt
If you want to exit the virtualenv, you can use:
deactivate
All optional dependencies are met.
Needed package dependencies are met.

When python3 creates a venv, it adds python into it!
This causes any upgrade recommendation to look like this:
/devel/v4l/docs/sphinx_1.7.9/bin/python3 -m venv sphinx_2.4.4
. sphinx_2.4.4/bin/activate
pip install -r ./Documentation/sphinx/requirements.txt
With is wrong (and it may not work). So, when recomending
an upgrade, exclude the venv dir from the search path, and
get the system's python.

If one is running a Sphinx version older than what's recommended,
but there's already a newer working virtual env, change the
text, as it is just a matter of switching to the new venv, instead
of creating a new one from scratch.

Mauro sez:
Patches 1 to 5 contain changes to the documentation toolset:
- The first 3 patches help to reduce a lot the number of reported
kernel-doc issues, by making the tool more smart.
- Patches 4 and 5 are meant to partially address the PDF
build, with now requires Sphinx version 2.4 or upper.
The remaining patches fix broken references detected by
this tool:
./scripts/documentation-file-ref-check
and address other random errors due to tags being mis-interpreted
or mis-used.
They are independent each other, but some may depend on
the kernel-doc improvements.
There are two ascii art drawings there. Use a block markup tag there
in order to get rid of those warnings:
./lib/bitmap.c:189: WARNING: Unexpected indentation.
./lib/bitmap.c:190: WARNING: Block quote ends without a blank line; unexpected unindent.
./lib/bitmap.c:190: WARNING: Unexpected indentation.
./lib/bitmap.c:191: WARNING: Line block ends without a blank line.
It should be noticed that there's actually a syntax violation
right now, as something like:
/**

@src:
will be handled as a definition for @src parameter, and not as
part of a diagram. So, we need to add something before it, in
order for this to be processed the way it should.

The Sphinx build system for PDF is too complex and generate
lots of ancillary files, including one PDF file for each
image.
So, at the end, the main latex dir has 156 pdf files, instead
of the 71 ones that would match each generated book. That's
confusing and it makes harder to identify when something didn't
work.
So, instead, let's move the final PDF output(s) to a separate
dir. This way, the latex/ dir will have the temporary and the
final *.tex files, while the final pdf files that built ok
will be under the pdf/ directory.
