When kernel-doc parses the sections for the documentation some errors
may occur. In many cases the warning is simply stored to the current
"entry" object. However, in the most of such cases this object gets
discarded and there is no way for the output engine to even know about
that. To avoid that, check if the "entry" is going to be discarded and
if there warnings have been collected, issue them to the current logger
as is and then flush the "entry". This fixes the problem that original
Perl implementation doesn't have.
As of Linux kernel v6.18-rc4 the reproducer can be:
$ scripts/kernel-doc -v -none -Wall include/linux/util_macros.h
...
Info: include/linux/util_macros.h:138 Scanning doc for function to_user_ptr
...
while with the proposed change applied it gives one more line:
$ scripts/kernel-doc -v -none -Wall include/linux/util_macros.h
...

Our documentation-related tools are spread out over various directories;
several are buried in the scripts/ dumping ground. That makes them harder
to discover and harder to maintain.
Recent work has started accumulating our documentation-related tools in
/tools/docs. This series nearly completes that task, moving most of the
rest of our various utilities there, hopefully fixing up all of the
relevant references in the process.
The one exception is scripts/kernel-doc; that move turned up some other
problems, so I have dropped it until those are ironed out.
At the end, rather than move the old, Perl kernel-doc, I simply removed it.
In the past, people would link to third-party mailing list archives
(like marc.info) for any kernel-related discussions. Now that there
is lore archive under kernel.org infrastructure, replace these marc
links
Note that the only remaining marc link is "Re: Memory mapping on Cirrus

The commit cause a warning:
Documentation/networking/skbuff.rst:34: WARNING: duplicate label crc, other instance in Documentation/translations/zh_CN/networking/skbuff.rst

The python version of the kernel-doc parser emits some strange warnings
with just a line number in certain cases:
$ ./scripts/kernel-doc -Wall -none 'include/linux/virtio_config.h'
Warning: 174
Warning: 184
Warning: 190
Warning: include/linux/virtio_config.h:226 No description found for return value of '__virtio_test_bit'
Warning: include/linux/virtio_config.h:259 No description found for return value of 'virtio_has_feature'
Warning: include/linux/virtio_config.h:283 No description found for return value of 'virtio_has_dma_quirk'
Warning: include/linux/virtio_config.h:392 No description found for return value of 'virtqueue_set_affinity'
I eventually tracked this down to the lone call of emit_msg() in the
KernelEntry class, which looks like:
self.emit_msg(self.new_start_line, f"duplicate section name '{name}'\n")
This looks like all the other emit_msg calls. Unfortunately, the definition
within the KernelEntry class takes only a message parameter and not a line
number. The intended message is passed as the warning!
Pass the filename to the KernelEntry class, and use this to build the log
message in the same way as the KernelDoc class does.
To avoid future errors, mark the warning parameter for both emit_msg
definitions as a keyword-only argument. This will prevent accidentally
passing a string as the warning parameter in the future.
Also fix the call in dump_section to avoid an unnecessary additional
newline.

common_*.rst files are snippets that are intended to be included by rtla
docs (rtla*.rst). common_options.rst in particular contains
substitutions which depend on other common_* includes, so building it
independently as reST source results in above errors.
Rename all common_*.rst files to common_*.txt to prevent Sphinx from
building these snippets as standalone reST source and update all include
references accordingly.

Quoth Mauro:
This series should probably be called:
"Move the trick-or-treat build hacks accumulated over time
into a single place and document them."
as this reflects its main goal. As such:
- it places the jobserver logic on a library;
- it removes sphinx/parallel-wrapper.sh;
- the code now properly implements a jobserver-aware logic
to do the parallelism when called via GNU make, failing back to
"-j" when there's no jobserver;
- converts check-variable-fonts.sh to Python and uses it via
function call;
- drops an extra script to generate man pages, adding a makefile
target for it;
- ensures that return code is 0 when PDF successfully builds;
- about half of the script is comments and documentation.
I tried to do my best to document all tricks that are inside the
script. This way, the docs build steps is now documented.
It should be noticed that it is out of the scope of this series
to change the implementation. Surely the process can be improved,
but first let's consolidate and document everything on a single
place.
Such script was written in a way that it can be called either
directly or via a Makefile. Running outside Makefile is
interesting specially when debug is needed. The command line
interface replaces the need of having lots of env vars before
calling sphinx-build:
$ ./tools/docs/sphinx-build-wrapper --help
usage: sphinx-build-wrapper [-h]
[--sphinxdirs SPHINXDIRS [SPHINXDIRS ...]] [--conf CONF]
[--builddir BUILDDIR] [--theme THEME] [--css CSS] [--paper {,a4,letter}] [-v]
[-j JOBS] [-i] [-V [VENV]]
{cleandocs,linkcheckdocs,htmldocs,epubdocs,texinfodocs,infodocs,mandocs,latexdocs,pdfdocs,xmldocs}
Kernel documentation builder
positional arguments:
{cleandocs,linkcheckdocs,htmldocs,epubdocs,texinfodocs,infodocs,mandocs,latexdocs,pdfdocs,xmldocs}
Documentation target to build
options:
-h, --help show this help message and exit
--sphinxdirs SPHINXDIRS [SPHINXDIRS ...]
Specific directories to build
--conf CONF Sphinx configuration file
--builddir BUILDDIR Sphinx configuration file
--theme THEME Sphinx theme to use
--css CSS Custom CSS file for HTML/EPUB
--paper {,a4,letter} Paper size for LaTeX/PDF output
-v, --verbose place build in verbose mode
-j, --jobs JOBS Sets number of jobs to use with sphinx-build
-i, --interactive Change latex default to run in interactive mode
-V, --venv [VENV] If used, run Sphinx from a venv dir (default dir: sphinx_latest)
the only mandatory argument is the target, which is identical with
"make" targets.
The call inside Makefile doesn't use the last four arguments. They're
there to help identifying problems at the build:
-v makes the output verbose;
-j helps to test parallelism;
-i runs latexmk in interactive mode, allowing to debug PDF
build issues;
-V is useful when testing it with different venvs.
When used with GNU make (or some other make which implements jobserver),
a call like:
make -j <targets> htmldocs
will make the wrapper to automatically use POSIX jobserver to claim
the number of available job slots, calling sphinx-build with a
"-j" parameter reflecting it. ON such case, the default can be
overriden via SPHINXDIRS argument.
Visiable changes when compared with the old behavior:
When V=0, the only visible difference is that:
- pdfdocs target now returns 0 on success, 1 on failures.
This addresses an issue over the current process where we
it always return success even on failures;
- it will now print the name of PDF files that failed to build,
if any.
In verbose mode, sphinx-build-wrapper and sphinx-build command lines
are now displayed.
Mauro says:
In the past, media used Docbook to generate documentation, together
with some logic to ensure that cross-references would match the
actual defined uAPI.
The rationale is that we wanted to automatically check for uAPI
documentation gaps.
The same logic was migrated to Sphinx. Back then, broken links
were reported. However, recent versions of it and/or changes at
conf.py disabled such checks.
The result is that several symbols are now not cross-referenced,
and we don't get warnings anymore when something breaks.
This series consist on 2 parts:
Part 1: extra patches to parse_data_structs.py and kernel_include.py;
Part 2: media documentation fixes.
There are lots of broken links on dmx. Those are mostly linked
to namespace handling.
Yet, some symbols were pointed to the wrong locations, and there
are some definitions that aren't needed.
