2017-08-24docs: fix minimal sphinx version in conf.pyMarkus Heiser1-1/+1
according to what Documentation/doc-guide/sphinx.rst says:: The ReST markups currently used by the Documentation/ files are meant to be built with ``Sphinx`` version 1.3 or upper. Signed-off-by: Markus Heiser <markus.heiser@darmarit.de> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2017-08-24docs: fix nested numbering in the TOCMarkus Heiser2-2/+0
With Sphinx 1.6 nested numbering is reported as warning:: ./input/joydev/index.rst:13: WARNING: input/joydev/joystick-api is already assigned section numbers (nested numbered toctree?) ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-func-open is already assigned section numbers (nested numbered toctree?) ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-func-close is already assigned section numbers (nested numbered toctree?) ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-func-ioctl is already assigned section numbers (nested numbered toctree?) ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-func-poll is already assigned section numbers (nested numbered toctree?) ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-ioc-adap-g-caps is already assigned section numbers (nested numbered toctree?) ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-ioc-adap-g-log-addrs is already assigned section numbers (nested numbered toctree?) ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-ioc-adap-g-phys-addr is already assigned section numbers (nested numbered toctree?) ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-ioc-dqevent is already assigned section numbers (nested numbered toctree?) ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-ioc-g-mode is already assigned section numbers (nested numbered toctree?) ./media/uapi/cec/cec-funcs.rst:8: WARNING: media/uapi/cec/cec-ioc-receive is already assigned section numbers (nested numbered toctree?)

2017-08-24docs-rst: pdf: use same vertical margin on all Sphinx versionsMauro Carvalho Chehab1-1/+1
Currently, on Sphinx up to version 1.4, pdf output uses a vertical margin of 1 inch. For upper versions, it uses a margin of 0.5 inches. That causes both page headers and footers to be very close to the margin of the sheet. Not all printers support writing like that. Also, there's no reason why the layout for newer versions would be different than for previous ones. So, standardize it, by always setting to 1 inch.

2017-08-24doc: Makefile: if sphinx is not found, run a check scriptMauro Carvalho Chehab1-0/+2
Right now, if the building system doesn't find Sphinx, it bails out, without providing any instructions about what should be done. Instead, run a script, providing some guidance about the steps needed for Sphinx build to work.

2017-08-07scripts/sphinx-pre-install: add minimum support for RHELMauro Carvalho Chehab1-12/+42
RHEL 7.x and clone distros are shipped with Sphinx 1.1.x, with is incompatible with Kernel ReST markups. So, on those systems, the only alternative is to install it via a Python virtual environment. While seeking for "pip" on CentOS 7.3, I noticed that it is not really needed, as python-virtualenv has its version packaged there already. So, remove this from the list of requirements for all distributions. With regards to PDF, we need at least texlive-tabulary extension, but that is not shipped there (at least on CentOS). So, disable PDF packages as a whole. Please notice, however, that texlive + amsmath is needed for ReST to properly handle ReST ".. math::" tags. Yet, Sphinx fall back to display the LaTeX math expressions as-is, if such extension is not available. So, let's just disable all texlive packages as a whole.

Documentation/gpu/drm-mm.rst includes from include/drm/drm_syncobj.h with :export:, but this is a header file without export directives. That results in this warning: ./include/drm/drm_syncobj.h:1: warning: no structured comments found ...and a failure to obtain the documentation from that file.

2017-07-23sphinx-pre-install: add support for MageiaMauro Carvalho Chehab1-1/+36
Add support for detecting and installing missing packages on Mageia. I opted to use "urpmi" at the install instructions, as this is present on Mageia since ever. Yet, if I were using Mageia 6, I would likely be using "dnf", as it is, IMHO, easier to use. Tested with Mageia 6.
