* doc: add maintainer bookTobin C. Harding2017-12-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is currently very little documentation in the kernel on maintainer level tasks. In particular there are no documents on creating pull requests to submit to Linus. Quoting Greg Kroah-Hartman on LKML: Anyway, this actually came up at the kernel summit / maintainer meeting a few weeks ago, in that "how do I make a good pull request to Linus" is something we need to document. Here's what I do, and it seems to work well, so maybe we should turn it into the start of the documentation for how to do it. (quote references: kernel summit, Europe 2017) Create a new kernel documentation book 'how to be a maintainer' (suggested by Jonathan Corbet). Add chapters on 'configuring git' and 'creating a pull request'. Most of the content was written by Linus Torvalds and Greg Kroah-Hartman in discussion on LKML. This is stated at the start of one of the chapters and the original email thread is referenced in 'pull-requests.rst'. Signed-off-by: Tobin C.

* Documentation/sphinx: add basic working Sphinx configuration and buildJani Nikula2016-05-301-0/+23
Add basic configuration and makefile to build documentation from any .rst files under Documentation using Sphinx. For starters, there's just the placeholder index.rst. At the top level Makefile, hook Sphinx documentation targets alongside (but independent of) the DocBook toolchain, having both be run on the various 'make *docs' targets. All Sphinx processing is placed into Documentation/Makefile.sphinx. Both that and the Documentation/DocBook/Makefile are now expected to handle all the documentation targets, explicitly ignoring them if they're not relevant for that particular toolchain. The changes to the existing DocBook Makefile are kept minimal. There is graceful handling of missing Sphinx and rst2pdf (which is needed for pdf output) by checking for the tool and python module, respectively, with informative messages to the user. If the Read the Docs theme (sphinx_rtd_theme) is available, use it, but otherwise gracefully fall back to the Sphinx default theme, with an informative message to the user, and slightly less pretty HTML output. Sphinx can now handle htmldocs, pdfdocs (if rst2pdf is available), epubdocs and xmldocs targets. The output documents are written into per output type subdirectories under Documentation/output. Finally, you can pass options to sphinx-build using the SPHINXBUILD make variable. For example, 'make SPHINXOPTS=-v htmldocs' for more verbose output from Sphinx. This is based on the original work by Jonathan Corbet, but he probably wouldn't recognize this as his own anymore. Signed-off-by: Jani Nikula <jani.nikula@intel.com>
