Jonathan Corbet a0ff711544 docs: Fix the docs build with Sphinx 6.0
commit 0283189e8f3d0917e2ac399688df85211f48447b upstream.

Sphinx 6.0 removed the execfile_() function, which we use as part of the
configuration process.  They *did* warn us...  Just open-code the
functionality as is done in Sphinx itself.

Tested (using SPHINX_CONF, since this code is only executed with an
alternative config file) on various Sphinx versions from 2.5 through 6.0.

Jonathan Corbet 6600ec2600 drm/i915: Maintain consistent documentation subsection ordering
commit 551bd3368a7b3cfef01edaade8970948d178d40a upstream.

With Sphinx 2.0 (or prior versions with the deprecation warnings fixed) the
docs build fails with:

  Documentation/gpu/i915.rst:403: WARNING: Title level inconsistent:

  Global GTT Fence Handling
  ~~~~~~~~~~~~~~~~~~~~~~~~~

  reST markup error:
  Documentation/gpu/i915.rst:403: (SEVERE/4) Title level inconsistent:

I "fixed" it by changing the subsections in i915.rst, but that didn't seem
like the correct change.  It turns out that a couple of i915 files create
their own subsections in kerneldoc comments using apostrophes as the
heading marker:

  Layout
  ''''''

That breaks the normal subsection marker ordering, and newer Sphinx is
rather more strict about enforcing that ordering.  So fix the offending
comments to make Sphinx happy.

(This is unfortunate, in that kerneldoc comments shouldn't need to be aware
of where they might be included in the heading hierarchy, but I don't see
a better way around it).

Jonathan Corbet 21158982f6 doc: Cope with Sphinx logging deprecations
commit 096ea522e84ea68f8e6c41e5e7294731a81e29bc upstream.

Recent versions of sphinx will emit messages like:

  Documentation/sphinx/kerneldoc.py:103:
     RemovedInSphinx20Warning: app.warning() is now deprecated.
     Use sphinx.util.logging instead.

Switch to sphinx.util.logging to make this unsightly message go away.
Alas, that interface was only added in version 1.6, so we have to add a
version check to keep things working with older sphinxes.

Jonathan Corbet c0742228bb doc: Cope with the deprecation of AutoReporter
commit 2404dad1f67f8917e30fc22a85e0dbcc85b99955 upstream.

AutoReporter is going away; recent versions of sphinx emit a warning like:

  Documentation/sphinx/kerneldoc.py:125:
      RemovedInSphinx20Warning: AutodocReporter is now deprecated.
      Use sphinx.util.docutils.switch_source_input() instead.

Make the switch.  But switch_source_input() only showed up in 1.7, so we
have to do ugly version checks to keep things working in older versions.

Jonathan Corbet d6331e0b14 Merge branch 'tglx-license' into docs-next
Thomas said:

There are a few bogus SPDX identifiers in various files and SPDX
Identifiers used in tree or about to be used which have no corresponding
License Text file in the LICENSES directory or use the new variant of the
GPL-2.0[+] license identifiers which are not mentioned in the GPL-2.0
Valid-License-Identifiers: tags.

There is no tool which can be used to scan the tree and also nothing which
helps people who submit patches to check their stuff before submission.

The following series cleans that up:

 - Add GPL-2.0-only and GPL-2.0-or-later identifiers to the GPL2.0 license
   and the Linux-syscall-note exception

 - Add X11, Apache-2.0, CC-BY-SA-4.0, CCDL-1.0, Linux-OpenIB license texts
   to the LICENSES directory along with the required documentation texts

 - Add a checker script which can read a single file or even a patch from
   the command line or does a full git tree scan

[Thomas also wins some sort of special prize for including an SPDX-checking
patch that complains about itself!]

Mike Rapoport says:

  These patches convert files in Documentation/vm to ReST format, add an
  initial index and link it to the top level documentation.

  There are no contents changes in the documentation, except few spelling
  fixes. The relatively large diffstat stems from the indentation and
  paragraph wrapping changes.

  I've tried to keep the formatting as consistent as possible, but I could
  miss some places that needed markup and add some markup where it was not
  necessary.

Jonathan Corbet fcdf1df203 Merge branch 'kerneldoc2' into docs-next
So once upon a time I set out to fix the problem reported by Tobin wherein
a literal block within a kerneldoc comment would be corrupted in
processing.  On the way, though, I got annoyed at the way I have to learn
how kernel-doc works from the beginning every time I tear into it.

As a result, seven of the following eight patches just get rid of some dead
code and reorganize the rest - mostly turning the 500-line process_file()
function into something a bit more rational.  Sphinx output is unchanged
after these are applied.  Then, at the end, there's a tweak to stop messing
with literal blocks.

If anybody was unaware that I've not done any serious Perl since the
1990's, they will certainly understand that fact now.

Jonathan Corbet af25029043 docs: kernel-doc: Don't mangle literal code blocks in comments
It can be useful to put code snippets into kerneldoc comments; that can be
done with the "::" operator at the end of a line like this::

   if (desperate)
       run_in_circles();

The ".. code-block::" directive can also be used to this end.  kernel-doc
currently fails to understand these literal blocks and applies its normal
markup to them, which is then treated as literal by sphinx.  The result is
unsightly markup instead of a useful code snippet.

Apply a hack to the output code to recognize literal blocks and avoid
performing any special markup on them.  It's ugly, but that means it fits
in well with the rest of the script.

I went about fixing just those found in Documentation/,

Documentation/devicetree/ for now.

Most of these changes were s/txt/rst/ or fixing up a path to an obvious

version to sleuth-out what content was actually being referenced and
then fixing the reference to point to the new file with that content.

Mauro says:

Sphinx installation is not trivial, as not all versions are supported,
and it requires a lot of stuff for math, images and PDF/LaTeX output
to work.

So, add a script that checks if everything is fine, providing
distro-specific hints about what's needed for it to work.

Like the rest of our documentation, this one could use some work.  There's
no mention of ioremap() and friends, no mention of io_read*() and friends.
But we have nice documentation for all those folks writing new drivers that
do port I/O :).

The :c:func: notation has been left off of all the read*/write* functions.
There's no kerneldoc comments for them anyway, so those links will never be
live, and writing a bunch of repetitive "read a byte from I/O memory"
comments lacks appeal.

Jonathan Corbet 3ed3e130ea Merge branch 'mauro-pdf' into docs-next
Mauro says:

This series address a series of errors during PDF generation from
media documentation.

The first patch fixes the late redefinition of a LaTeX command at the
Sphinx LaTeX style that causes build to break when some cross-references
are used.

The next two patches fix PDF output issues with subdev-formats.rst.

The next 3 patches fix image includes and their output for PDF.

It is aligned with Linus request of not having binary-generated images
from their SVG source codes.

I still intend to move the remaing PNG images to vectorial ones (SVG),
as image scale works better, but this will require some additional work.
When done, I'll submit as a separate patch series.

It should also be noticed that the last patch violates the output dir,
when make is used with "O=some_dir", as Sphinx doesn't accept
image files outside the source directory. We'll likely need some Sphinx
extension in order to fix it, but at least with this series (plus Jani Nikola's
PDF fix series), the PDF output should work fine again.

Jonathan Corbet 7358bb2f32 docs: Clean up and organize the admin guide a bit
The admin guide is a good start, but it's time to turn it into something
better than an unordered blob of files.  This is a first step in that
direction.  The TOC has been split up and annotated, the guides have been
reordered, and minor tweaks have been applied to a few of them.

One consequence of splitting up the TOC is that we don't really want to use
:numbered: anymore, since the count resets every time and there doesn't
seem to be a way to change that.  Eventually we probably want to group the
documents into sub-books, at which point we can go back to a single TOC,
but it's probably early to do that.
