2026-03-04docs: kdoc: fix logic to handle unissued warningsMauro Carvalho Chehab1-7/+28
[ Upstream commit 292eca3163218f2185a8eabe59f4a576bb9e05f8 ] Changeset 469c1c9eb6c9 ("kernel-doc: Issue warnings that were silently discarded") didn't properly addressed the missing messages behavior, as it was calling directly python logger low-level function, instead of using the expected method to emit warnings. Basically, there are two methods to log messages: - self.config.log.warning() - This is the raw level to emit a warning. It just writes the a message at stderr, via python logging, as it is initialized as: self.config.log = logging.getLogger("kernel-doc") - self.config.warning() - This is where we actually consider a message as a warning, properly incrementing error count. Due to that, several parsing error messages are internally considered as success, causing -Werror to not work on such messages. While here, ensure that the last ignored entry will also be handled by adding an extra check at the end of the parse handler.

2025-11-29docs: kdoc: various fixes for grammar, spelling, punctuationRandy Dunlap5-26/+26
Correct grammar, spelling, and punctuation in comments, strings, print messages, logs. Change two instances of two spaces between words to just one space. codespell was used to find misspelled words.

2025-11-29docs: kdoc_parser: use '@' for Excess enum valueRandy Dunlap1-1/+1
kdoc is looking for "@value" here, so use that kind of string in the warning message. The "%value" can be confusing. This changes: Warning: drivers/net/wireless/mediatek/mt76/testmode.h:92 Excess enum value '%MT76_TM_ATTR_TX_PENDING' description in 'mt76_testmode_attr' to this: Warning: drivers/net/wireless/mediatek/mt76/testmode.h:92 Excess enum value '@MT76_TM_ATTR_TX_PENDING' description in 'mt76_testmode_attr' Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reviewed-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net> Message-ID: <20251126061752.3497106-1-rdunlap@infradead.org>
2025-11-29docs: kdoc_parser: add data/function attributes to ignoreRandy Dunlap1-0/+3
Recognize and ignore __rcu (in struct members), __private (in struct members), and __always_unused (in function parameters) to prevent kernel-doc warnings: Warning: include/linux/rethook.h:38 struct member 'void (__rcu *handler' not described in 'rethook' Warning: include/linux/hrtimer_types.h:47 Invalid param: enum hrtimer_restart (*__private function)(struct hrtimer *) Warning: security/ipe/hooks.c:81 function parameter '__always_unused' not described in 'ipe_mmap_file' Warning: security/ipe/hooks.c:109 function parameter '__always_unused' not described in 'ipe_file_mprotect' There are more of these (in compiler_types.h, compiler_attributes.h) that can be added as needed.

2025-11-21tools/docs/get_feat.py: convert get_feat.pl to PythonMauro Carvalho Chehab1-0/+494
As we want to call Python code directly at the Sphinx extension, convert get_feat.pl to Python. The code was made to be (almost) bug-compatible with the Perl version, with two exceptions: 1. Currently, Perl script outputs a wrong table if arch is set to a non-existing value; 2. the ReST table output when --feat is used without --arch has an invalid format, as the number of characters for the table delimiters are wrong. Those two bugs were fixed while testing the conversion. Additionally, another caveat was solved: the output when --feat is used without arch and the feature doesn't exist doesn't contain an empty table anymore.

2025-11-18docs: bring some order to our Python module hierarchyJonathan Corbet9-10/+10
Now that we have tools/lib/python for our Python modules, turn them into proper packages with a single namespace so that everything can just use tools/lib/python in sys.path. No functional change. Signed-off-by: Jonathan Corbet <corbet@lwn.net> Message-ID: <20251110220430.726665-3-corbet@lwn.net>
2025-11-18docs: Move the python libraries to tools/lib/pythonJonathan Corbet14-0/+5422
"scripts/lib" was always a bit of an awkward place for Python modules. We already have tools/lib; create a tools/lib/python, move the libraries there, and update the users accordingly. While at it, move the contents of tools/docs/lib. Rather than make another directory, just put these documentation-oriented modules under "kdoc".
