2024-04-02doc: netlink: Add hyperlinks to generated Netlink docsDonald Hunter1-18/+42
Update ynl-gen-rst to generate hyperlinks to definitions, attribute sets and sub-messages from all the places that reference them. Note that there is a single label namespace for all of the kernel docs. Hyperlinks within a single netlink doc need to be qualified by the family name to avoid collisions. The label format is 'family-type-name' which gives, for example, 'rt-link-attribute-set-link-attrs' as the link id.

2024-04-02doc: netlink: Change generated docs to limit TOC to depth 3Donald Hunter1-1/+1
The tables of contents in the generated Netlink docs include individual attribute definitions. This can make the contents exceedingly long and repeats a lot of what is on the rest of the pages. See for example: https://docs.kernel.org/networking/netlink_spec/tc.html Add a depth limit to the contents directive in generated .rst files to limit the contents depth to 3 levels. This reduces the contents to: - Family - Summary - Operations - op-one - op-two - ... - Definitions - struct-one - struct-two - enum-one - ... - Attribute sets - attrs-one - attrs-two - ...

2023-12-19tools/net/ynl-gen-rst: Remove extra indentation from generated docsDonald Hunter1-3/+3
The output from ynl-gen-rst.py has extra indentation that causes extra <blockquote> elements to be generated in the HTML output. Reduce the indentation so that sphinx doesn't generate unnecessary <blockquote> elements.

2023-12-19tools/net/ynl-gen-rst: Remove bold from attribute-set headingsDonald Hunter1-1/+1
The generated .rst for attribute-sets currently uses a sub-sub-heading for each attribute, with the attribute name in bold. This makes attributes stand out more than the attribute-set sub-headings they are part of. Remove the bold markup from attribute sub-sub-headings.

To increase the chances of people finding the rendered docs add a link to specs.rst and index.rst. Add a label in the generated index.rst and while at it adjust the title a little bit.

2023-11-24Documentation: Document each netlink familyBreno Leitao1-0/+388
This is a simple script that parses the Netlink YAML spec files (Documentation/netlink/specs/), and generates RST files to be rendered in the Network -> Netlink Specification documentation page. Create a python script that is invoked during 'make htmldocs', reads the YAML specs input file and generate the correspondent RST file. Create a new Documentation/networking/netlink_spec index page, and reference each Netlink RST file that was processed above in this main index.rst file. In case of any exception during the parsing, dump the error and skip the file. Do not regenerate the RST files if the input files (YAML) were not changed in-between invocations. Suggested-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Breno Leitao <leitao@debian.org> ---- Changelog: V3: * Do not regenerate the RST files if the input files were not changed. In order to do it, a few things changed: - Rely on Makefile more to find what changed, and trigger individual file processing - The script parses file by file now (instead of batches) - Create a new option to generate the index file V2: * Moved the logic from a sphinx extension to a external script * Adjust some formatting as suggested by Donald Hunter and Jakub * Auto generating all the rsts instead of having stubs * Handling error gracefully Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.
