2022-07-14docs: process: remove outdated submitting-drivers.rstLukas Bulwahn1-2/+1
Commit 31b24bee3357 ("docs: add a warning to submitting-drivers.rst") in October 2016 already warns "This (...) should maybe just be deleted, but I'm not quite ready to do that yet". Maybe, six years ago, we were not ready but let us remove old content for the better now and structure and maintain less content in the kernel documentation with a better result. Drop this already outdated document and adjust all textual references. Here is an argument why deleting the content will not remove any useful information to the existing kernel documentation, individually broken down for each section. Section "Allocating Device Numbers" refers to https://www.lanana.org/, and then refers to Documentation/admin-guide/devices.rst. However, the devices.rst clearly states: "The version of this document at lanana.org is no longer maintained." Everything needed for submitting drivers is already stated in devices.rst and the reference to https://www.lanana.org/ is outdated, and should be just deleted. Section "Who To Submit Drivers To" is all about Linux 2.0 - 2.6, before the new release version scheme; the mentioned developers are still around, but actually not the first developers to contact anymore. Section "What Criteria Determine Acceptance" has a few bullet points: Licensing and Copyright is well-covered in process/kernel-license.rst. Interfaces, Code, Portability, Clarity state some obvious things about ensuring kernel code quality. Control suggests to add a MAINTAINERS entry, which is already mentioned in 6.Followthrough.rst: "... added yourself to the MAINTAINERS file..." PM support states a bit about implementing and testing power management of a driver, it remains an open question where to place that in the process documents. Driver developers interested in power management will find the corresponding part on power management in the kernel documentation anyway. In section "What Criteria Do Not Determine Acceptance", the points Vendor and Author states something basic consequence of the kernel being an open-source community software development. Probably no need to mention it nowadays. Section "Resources" lists resources that are also mentioned elsewhere more central. - Linux kernel tree and mailing list is mentioned in many places. - https://lwn.net/Kernel/LDD3/ is mentioned in Documentation/process/kernel-docs.rst. - https://lwn.net/ is mentioned in: - Documentation/process/8.Conclusion.rst - Documentation/process/kernel-docs.rst - https://kernelnewbies.org/ is mentioned in: - Documentation/process/8.Conclusion.rst - Documentation/process/kernel-docs.rst - http://www.linux-usb.org/ is mentioned in Documentation/driver-api/usb/usb.rst - https://landley.net/kdocs/ols/2002/ols2002-pages-545-555.pdf is mentioned in Documentation/process/kernel-docs.rst - https://kernelnewbies.org/KernelJanitors is mentioned in Documentation/process/howto.rst - https://git-scm.com/ is mentioned in - Documentation/process/2.Process.rst - Documentation/process/7.AdvancedTopics.rst - Documentation/process/howto.rst Signed-off-by: Lukas Bulwahn <lukas.bulwahn@gmail.com> Link: https://lore.kernel.org/r/20220704122537.3407-7-lukas.bulwahn@gmail.com Signed-off-by: Jonathan Corbet <corbet@lwn.net>
2022-04-05Documentation: kernel-hacking: minor edits for styleKonstantin Ryabitsev2-22/+19
Rusty's kernel-hacking guides provide important information, however they are written in a narrative style that some readers may interpret as off-putting. Since the goal is to make kernel documentation accessible to as many new developers as possible, it's best to avoid the turns of phrase that require a specific cultural context to properly understand.

2020-12-31docs: Fix reST markup when linking to sectionsNícolas F. R. A. Prado1-4/+4
During the process of converting the documentation to reST, some links were converted using the following wrong syntax (and sometimes using %20 instead of spaces): `Display text <#section-name-in-html>`__ This syntax isn't valid according to the docutils' spec [1], but more importantly, it is specific to HTML, since it uses '#' to link to an HTML anchor. The right syntax would instead use a docutils hyperlink reference as the embedded URI to point to the section [2], that is: `Display text <Section Name_>`__ This syntax works in both HTML and PDF. The LaTeX toolchain doesn't mind the HTML anchor syntax when generating the pdf documentation (make pdfdocs), that is, the build succeeds but the links don't work, but that syntax causes errors when trying to build using the not-yet-merged rst2pdf: ValueError: format not resolved, probably missing URL scheme or undefined destination target for 'Forcing%20Quiescent%20States' So, use the correct syntax in order to have it work in all different output formats.

2020-03-20docs: prevent warnings due to autosectionlabelMauro Carvalho Chehab1-2/+2
Changeset 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst") enabled a new feature at Sphinx: it will now generate index for each document title, plus to each chapter inside it. There's a drawback, though: one document cannot have two sections with the same name anymore. A followup patch will change the logic of autosectionlabel to avoid most creating references for every single section title, but still we need to be able to reference the chapters inside a document. There are a few places where there are two chapters with the same name. This patch renames one of the chapters, in order to avoid symbol conflict within the same document. PS.: as I don't speach Chinese, I had some help from a friend (Wen Liu) at the Chinese translation for "publishing patches" for this document: Documentation/translations/zh_CN/process/5.Posting.rst Fixes: 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst") Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/2bffb91e4a63d41bf5fae1c23e1e8b3bba0b8806.1584716446.git.mchehab+huawei@kernel.org Signed-off-by: Jonathan Corbet <corbet@lwn.net>

2019-07-15docs: locking: convert docs to ReST and rename to *.rstMauro Carvalho Chehab1-1/+1
Convert the locking documents to ReST and add them to the kernel development book where it belongs. Most of the stuff here is just to make Sphinx to properly parse the text file, as they're already in good shape, not requiring massive changes in order to be parsed. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.
