[PATCH v4 00/18] kernel-doc: add supported to document nested structs

[PATCH v4 00/18] kernel-doc: add supported to document nested structs

[Mauro Carvalho Chehab]

Hi Jon,

This is a rebased version of my patch series that add support for
nested structs on kernel-doc. With this version, it won't produce anymore
hundreds of identical warnings, as patch 17 removes the warning
duplication.

Excluding warnings about duplicated Note: section at hash.h, before
this series, it reports 166 kernel-doc warnings. After this patch series,
it reports 123 kernel-doc warnings, being 51 from DVB. I have already a patch
series that will cleanup those new DVB warnings due to nested structs.

So, the net result is that the number of warnings is reduced with
this version.

-

Right now, it is not possible to document nested struct and nested unions.
kernel-doc simply ignore them.

Add support to document them.

Patches 1 to 6 improve kernel-doc documentation to reflect what
kernel-doc currently supports and import some stuff from the
old kernel-doc-nano-HOWTO.txt.

Patch 7 gets rid of the old documentation (kernel-doc-nano-HOWTO.txt).

Patch 8 gets rid of the now unused output formats for kernel-doc: since 
we got rid of all DocBook stuff, we should not need them anymore. The
reason for dropping it (despite cleaning up), is that it doesn't make 
sense to invest time on adding new features for formats that aren't
used anymore.

Patch 9 improves argument handling, printing script usage if an
invalid argument is passed and accepting both -cmd and --cmd
forms.

Patch 10 changes the default output format to ReST, as this is a way
more used than man output nowadays.

Patch 11 solves an issue after ReST conversion, where tabs were not
properly handled on kernel-doc tags.

Patch 12 adds support for parsing kernel-doc nested structures and 
unions.

Patch 13 does a cleanup, removing $nexted parameter at the
routines that handle structs.

Patch 14 Improves warning output by printing the identifier where
the warning occurred.

Patch 15 complements patch 12, by adding support for function
definitions inside nested structures. It is needed by some media
docs with use such kind of things.

Patch 16 improves nested struct handling even further, allowing it
to handle cases where a nested named struct/enum with multiple
identifiers added (e. g. struct { ... } foo, bar;).

Patch 17 avoid warnings when -function or -nofunction is used and
the symbol to be warned is not listed.

Patch 18 adds documentation for nested union/struct inside w1_netlink.

The entire patch series are at my development tree, at:
    https://git.linuxtv.org/mchehab/experimental.git/log/?h=nested-fix-v4b

--

v4:
- Rebased on the top of Dec, 18 docs-next branch;
- Don't print multiple times the same error, when a single file is
  parsed multiple times with -function NAME or -nofunction NAME.

v3:
- rebased on the top of docs-next branch at docs git tree;
- patches reordered to a more logical sequence;
- Change script to produce ReST format by default;
- Improve argument handling;
- Accept structs with multiple identifiers.


v2:
  - solved some issues that Randy pointed;
  - added patch 10 as suggested by Markus;
  - Fixed some bugs on patch 9, after parsing nested structs
   on media subsystem;
  - added patch 11 with a warning improvement fixup;
  - added patch 12 in order to handle function parameters
   on nested structures, due to DVB demux kAPI.

v1:
  - original version.

[PATCH v4 01/18] docs: kernel-doc.rst: better describe kernel-doc arguments

[Mauro Carvalho Chehab]

Add a new section to describe kernel-doc arguments,
adding examples about how identation should happen, as failing
to do that causes Sphinx to do the wrong thing.

not the way it should be ;-)

Fix it and move it to happen earlier.

-=====================
-
-How to format kernel-doc comments
----------------------------------
-
-In order to provide embedded, 'C' friendly, easy to maintain,
-but consistent and extractable documentation of the functions and
-data structures in the Linux kernel, the Linux kernel has adopted
-a consistent style for documenting functions and their parameters,
-and structures and their members.
-
-The format for this documentation is called the kernel-doc format.
-It is documented in this Documentation/kernel-doc-nano-HOWTO.txt file.
-
-This style embeds the documentation within the source files, using
-a few simple conventions.  The scripts/kernel-doc perl script, the
-Documentation/sphinx/kerneldoc.py Sphinx extension and other tools understand
-these conventions, and are used to extract this embedded documentation
-into various documents.
-
-In order to provide good documentation of kernel functions and data
-structures, please use the following conventions to format your
-kernel-doc comments in Linux kernel source.
-
-We definitely need kernel-doc formatted documentation for functions
-that are exported to loadable modules using EXPORT_SYMBOL.
-
-We also look to provide kernel-doc formatted documentation for
-functions externally visible to other kernel files (not marked
-"static").
-
-We also recommend providing kernel-doc formatted documentation
-for private (file "static") routines, for consistency of kernel
-source code layout.  But this is lower priority and at the
-discretion of the MAINTAINER of that kernel source file.
-
-Data structures visible in kernel include files should also be
-documented using kernel-doc formatted comments.
-
-The opening comment mark "/**" is reserved for kernel-doc comments.
-Only comments so marked will be considered by the kernel-doc scripts,
-and any comment so marked must be in kernel-doc format.  Do not use
-"/**" to be begin a comment block unless the comment block contains
-kernel-doc formatted comments.  The closing comment marker for
-kernel-doc comments can be either "*/" or "**/", but "*/" is
-preferred in the Linux kernel tree.
-
-Kernel-doc comments should be placed just before the function
-or data structure being described.
-
-Example kernel-doc function comment:
-
-/**

-The longer description formatting is "reflowed", losing your line

-the formatting.
-
-See the section below "How to add extractable documentation to your
-source files" for more details and notes on how to format kernel-doc
-comments.
-
-Components of the kernel-doc system
------------------------------------
-
-Many places in the source tree have extractable documentation in the
-form of block comments above functions.  The components of this system
-are:
-
-- scripts/kernel-doc
-
-  This is a perl script that hunts for the block comments and can mark
-  them up directly into DocBook, ReST, man, text, and HTML. (No, not
-  texinfo.)
-
-- scripts/docproc.c
-
-  This is a program for converting SGML template files into SGML
-  files. When a file is referenced it is searched for symbols
-  exported (EXPORT_SYMBOL), to be able to distinguish between internal
-  and external functions.
-  It invokes kernel-doc, giving it the list of functions that
-  are to be documented.
-  Additionally it is used to scan the SGML template files to locate
-  all the files referenced herein. This is used to generate dependency
-  information as used by make.
-
-- Makefile
-
-  The targets 'xmldocs', 'latexdocs', 'pdfdocs', 'epubdocs'and 'htmldocs'
-  are used to build XML DocBook files, LaTeX files, PDF files,
-  ePub files and html files in Documentation/.
-
-How to extract the documentation
---------------------------------
-
-If you just want to read the ready-made books on the various
-subsystems, just type 'make epubdocs', or 'make pdfdocs', or 'make htmldocs',
-depending on your preference.  If you would rather read a different format,
-you can type 'make xmldocs' and then use DocBook tools to convert
-Documentation/output/*.xml to a format of your choice (for example,
-'db2html ...' if 'make htmldocs' was not defined).
-
-If you want to see man pages instead, you can do this:
-
-$ cd linux
-$ scripts/kernel-doc -man $(find -name '*.c') | split-man.pl /tmp/man
-$ scripts/kernel-doc -man $(find -name '*.h') | split-man.pl /tmp/man
-
-Here is split-man.pl:
-
--->
-#!/usr/bin/perl
-
-if ($#ARGV < 0) {
-   die "where do I put the results?\n";
-}
-
-mkdir $ARGV[0],0777;
-$state = 0;
-while (<STDIN>) {
-    if (/^\.TH \"[^\"]*\" 9 \"([^\"]*)\"/) {
-	if ($state == 1) { close OUT }
-	$state = 1;
-	$fn = "$ARGV[0]/$1.9";
-	print STDERR "Creating $fn\n";
-	open OUT, ">$fn" or die "can't open $fn: $!\n";
-	print OUT $_;
-    } elsif ($state != 0) {
-	print OUT $_;
-    }
-}
-
-close OUT;
-<--
-
-If you just want to view the documentation for one function in one
-file, you can do this:
-
-$ scripts/kernel-doc -man -function fn file | nroff -man | less
-
-or this:
-
-$ scripts/kernel-doc -text -function fn file
-
-
-How to add extractable documentation to your source files
----------------------------------------------------------
-
-The format of the block comment is like this:
-
-/**
- * function_name(:)? (- short description)?
-(* @parameterx(space)*: (description of parameter x)?)*
-(* a blank line)?
- * (Description:)? (Description of function)?
- * (section header: (section description)? )*
-(*)?*/
-
-All "description" text can span multiple lines, although the
-function_name & its short description are traditionally on a single line.
-Description text may also contain blank lines (i.e., lines that contain
-only a "*").
-
-"section header:" names must be unique per function (or struct,
-union, typedef, enum).
-
-Use the section header "Return" for sections describing the return value
-of a function.
-
-Avoid putting a spurious blank line after the function name, or else the
-description will be repeated!
-
-All descriptive text is further processed, scanning for the following special
-patterns, which are highlighted appropriately.
-
-'funcname()' - function
-'$ENVVAR' - environment variable
-'&struct_name' - name of a structure (up to two words including 'struct')
-'@parameter' - name of a parameter
-'%CONST' - name of a constant.
-
-NOTE 1:  The multi-line descriptive text you provide does *not* recognize
-line breaks, so if you try to format some text nicely, as in:
-
-  Return:
-    0 - cool
-    1 - invalid arg
-    2 - out of memory
-
-this will all run together and produce:
-
-  Return: 0 - cool 1 - invalid arg 2 - out of memory
-
-NOTE 2:  If the descriptive text you provide has lines that begin with
-some phrase followed by a colon, each of those phrases will be taken as
-a new section heading, which means you should similarly try to avoid text
-like:
-
-  Return:
-    0: cool
-    1: invalid arg
-    2: out of memory
-
-every line of which would start a new section.  Again, probably not
-what you were after.
-
-Take a look around the source tree for examples.
-
-
-kernel-doc for structs, unions, enums, and typedefs
----------------------------------------------------
-
-Beside functions you can also write documentation for structs, unions,
-enums and typedefs. Instead of the function name you must write the name
-of the declaration;  the struct/union/enum/typedef must always precede
-the name. Nesting of declarations is not supported.
-Use the argument mechanism to document members or constants.
-
-Inside a struct description, you can use the "private:" and "public:"
-comment tags.  Structure fields that are inside a "private:" area
-are not listed in the generated output documentation.  The "private:"
-and "public:" tags must begin immediately following a "/*" comment
-marker.  They may optionally include comments between the ":" and the
-ending "*/" marker.
-
-Example:
-
-/**
- * struct my_struct - short description
- * @a: first member
- * @b: second member
- *
- * Longer description
- */
-struct my_struct {
-    int a;
-    int b;
-/* private: internal use only */
-    int c;
-};
-
-
-Including documentation blocks in source files
-----------------------------------------------
-
-To facilitate having source code and comments close together, you can
-include kernel-doc documentation blocks that are free-form comments
-instead of being kernel-doc for functions, structures, unions,
-enums, or typedefs.  This could be used for something like a
-theory of operation for a driver or library code, for example.
-
-This is done by using a DOC: section keyword with a section title.  E.g.:
-
-/**
- * DOC: Theory of Operation
- *
- * The whizbang foobar is a dilly of a gizmo.  It can do whatever you
- * want it to do, at any time.  It reads your mind.  Here's how it works.
- *
- * foo bar splat
- *
- * The only drawback to this gizmo is that is can sometimes damage
- * hardware, software, or its subject(s).
- */
-
-DOC: sections are used in ReST files.

[PATCH v4 08/18] scripts: kernel-doc: get rid of unused output formats

[Mauro Carvalho Chehab]

Since there isn't any docbook code anymore upstream,
we can get rid of several output formats:

- docbook/xml, html, html5 and list formats were used by
  the old build system;
- As ReST is text, there's not much sense on outputting
  on a different text format.

After this patch, only man and rst output formats are
supported.

[PATCH v4 09/18] scripts: kernel-doc: improve argument handling

[Mauro Carvalho Chehab]

Right now, if one uses "--rst" instead of "-rst", it just
ignore the argument and produces a man page. Change the
logic to accept both "-cmd" and "--cmd". Also, if
"cmd" doesn't exist, print the usage information and exit.

[PATCH v4 10/18] scripts: kernel-doc: change default to ReST format

[Mauro Carvalho Chehab]

Right now, if kernel-doc is called without arguments, it
defaults to man pages. IMO, it makes more sense to
default to ReST, as this is the output that it is most
used nowadays, and it easier to check if everything got
parsed fine on an enriched text mode format.

[PATCH v4 11/18] scripts: kernel-doc: replace tabs by spaces

[Mauro Carvalho Chehab]

Sphinx has a hard time dealing with tabs, causing it to
misinterpret paragraph continuation.

As we're now mainly focused on supporting ReST output,
replace tabs by spaces, in order to avoid troubles when
the output is parsed by Sphinx.

[PATCH v4 12/18] scripts: kernel-doc: parse next structs/unions

[Mauro Carvalho Chehab]

There are several places within the Kernel tree with nested
structs/unions, like this one:

  struct ingenic_cgu_clk_info {
    const char *name;
    enum {
      CGU_CLK_NONE = 0,
      CGU_CLK_EXT = BIT(0),
      CGU_CLK_PLL = BIT(1),
      CGU_CLK_GATE = BIT(2),
      CGU_CLK_MUX = BIT(3),
      CGU_CLK_MUX_GLITCHFREE = BIT(4),
      CGU_CLK_DIV = BIT(5),
      CGU_CLK_FIXDIV = BIT(6),
      CGU_CLK_CUSTOM = BIT(7),
    } type;
    int parents[4];
    union {
      struct ingenic_cgu_pll_info pll;
      struct {
        struct ingenic_cgu_gate_info gate;
        struct ingenic_cgu_mux_info mux;
        struct ingenic_cgu_div_info div;
        struct ingenic_cgu_fixdiv_info fixdiv;
      };
      struct ingenic_cgu_custom_info custom;
    };
  };

Currently, such struct is documented as:

	**Definition**

	::
	struct ingenic_cgu_clk_info {
	    const char * name;
	};

	**Members**

	``name``
	  name of the clock

With is obvioulsy wrong. It also generates an error:
	drivers/clk/ingenic/cgu.h:169: warning: No description found for parameter 'enum'

However, there's nothing wrong with this kernel-doc markup: everything
is documented there.

It makes sense to document all fields there. So, add a
way for the core to parse those structs.

With this patch, all documented fields will properly generate
documentation.

[PATCH v4 13/18] scripts: kernel-doc: get rid of $nested parameter

[Mauro Carvalho Chehab]

The check_sections() function has a $nested parameter, meant
to identify when a nested struct is present. As we now have
a logic that handles it, get rid of such parameter.

[PATCH v4 14/18] scripts: kernel-doc: print the declaration name on warnings

[Mauro Carvalho Chehab]

The logic at create_parameterlist()'s ancillary push_parameter()
function has already a way to output the declaration name, with
would help to discover what declaration is missing.

However, currently, the logic is utterly broken, as it uses
the var $type with a wrong meaning. With the current code,
it will never print anything. I suspect that originally
it was using the second argument of output_declaration().

I opted to not rely on a globally defined $declaration_name,
but, instead, to pass it explicitly as a parameter.

While here, I removed a unaligned check for !$anon_struct_union.
This is not needed, as, if $anon_struct_union is not zero,
$parameterdescs{$param} will be defined.

	} st1, st2, *st3, st4;
};

Handling it requires to split each parameter. Change the logic
to allow such definitions.

In order to test the new nested logic, the following file
was used to test

<code>
struct foo { int a; }; /* Just to avoid errors if compiled */

/**
 * struct my_struct - a struct with nested unions and structs
 * @arg1: first argument of anonymous union/anonymous struct
 * @arg2: second argument of anonymous union/anonymous struct
 * @arg1b: first argument of anonymous union/anonymous struct
 * @arg2b: second argument of anonymous union/anonymous struct
 * @arg3: third argument of anonymous union/anonymous struct
 * @arg4: fourth argument of anonymous union/anonymous struct
 * @bar.st1.arg1: first argument of struct st1 on union bar
 * @bar.st1.arg2: second argument of struct st1 on union bar
 * @bar.st1.bar1: bar1 at st1
 * @bar.st1.bar2: bar2 at st1
 * @bar.st2.arg1: first argument of struct st2 on union bar
 * @bar.st2.arg2: second argument of struct st2 on union bar
 * @bar.st3.arg2: second argument of struct st3 on union bar
 * @f1: nested function on anonimous union/struct
 * @bar.st2.f2: nested function on named union/struct
 */
struct my_struct {
   /* Anonymous union/struct*/
   union {
	struct {
	    char arg1 : 1;
	    char arg2 : 3;
	};
       struct {
           int arg1b;
           int arg2b;
       };
       struct {
           void *arg3;
           int arg4;
           int (*f1)(char foo, int bar);
       };
   };
   union {
       struct {
           int arg1;
           int arg2;
	   struct foo bar1, *bar2;
       } st1;           /* bar.st1 is undocumented, cause a warning */
       struct {
           void *arg1;  /* bar.st3.arg1 is undocumented, cause a warning */
	    int arg2;
          int (*f2)(char foo, int bar); /* bar.st3.fn2 is undocumented, cause a warning */
       } st2, st3, *st4;
       int (*f3)(char foo, int bar); /* f3 is undocumented, cause a warning */
   } bar;               /* bar is undocumented, cause a warning */

   /* private: */
   int undoc_privat;    /* is undocumented but private, no warning */

   /* public: */
   int undoc_public;    /* is undocumented, cause a warning */
};
</code>

It produces the following warnings, as expected:

test2.h:57: warning: Function parameter or member 'bar' not described in 'my_struct'
test2.h:57: warning: Function parameter or member 'bar.st1' not described in 'my_struct'

[PATCH v4 17/18] scripts: kernel-doc: apply filtering rules to warnings

[Mauro Carvalho Chehab]

When kernel-doc is called with output selection filters,
it will be called lots of time for a single file. If
there is a warning present there, it means that it may
print hundreds of identical warnings.

Worse than that, the -function NAME actually filters only
functions. So, it makes no sense at all to print warnings
for structs or enums.

0d7f488f0 Stephan Mueller 2014-11-12  367   * @cra_flags: Flags describing this transformation. See include/linux/crypto.h
0d7f488f0 Stephan Mueller 2014-11-12  368   *	       CRYPTO_ALG_* flags for the flags which go in here. Those are
0d7f488f0 Stephan Mueller 2014-11-12  369   *	       used for fine-tuning the description of the transformation
0d7f488f0 Stephan Mueller 2014-11-12  370   *	       algorithm.
0d7f488f0 Stephan Mueller 2014-11-12  371   * @cra_blocksize: Minimum block size of this transformation. The size in bytes
0d7f488f0 Stephan Mueller 2014-11-12  372   *		   of the smallest possible unit which can be transformed with
0d7f488f0 Stephan Mueller 2014-11-12  373   *		   this algorithm. The users must respect this value.
0d7f488f0 Stephan Mueller 2014-11-12  374   *		   In case of HASH transformation, it is possible for a smaller
0d7f488f0 Stephan Mueller 2014-11-12  375   *		   block than @cra_blocksize to be passed to the crypto API for
0d7f488f0 Stephan Mueller 2014-11-12  376   *		   transformation, in case of any other transformation type, an
0d7f488f0 Stephan Mueller 2014-11-12  377   * 		   error will be returned upon any attempt to transform smaller
0d7f488f0 Stephan Mueller 2014-11-12  378   *		   than @cra_blocksize chunks.
0d7f488f0 Stephan Mueller 2014-11-12  379   * @cra_ctxsize: Size of the operational context of the transformation. This
0d7f488f0 Stephan Mueller 2014-11-12  380   *		 value informs the kernel crypto API about the memory size
0d7f488f0 Stephan Mueller 2014-11-12  381   *		 needed to be allocated for the transformation context.
0d7f488f0 Stephan Mueller 2014-11-12  382   * @cra_alignmask: Alignment mask for the input and output data buffer. The data
0d7f488f0 Stephan Mueller 2014-11-12  383   *		   buffer containing the input data for the algorithm must be
0d7f488f0 Stephan Mueller 2014-11-12  384   *		   aligned to this alignment mask. The data buffer for the
0d7f488f0 Stephan Mueller 2014-11-12  385   *		   output data must be aligned to this alignment mask. Note that
0d7f488f0 Stephan Mueller 2014-11-12  386   *		   the Crypto API will do the re-alignment in software, but
0d7f488f0 Stephan Mueller 2014-11-12  387   *		   only under special conditions and there is a performance hit.
0d7f488f0 Stephan Mueller 2014-11-12  388   *		   The re-alignment happens at these occasions for different
0d7f488f0 Stephan Mueller 2014-11-12  389   *		   @cra_u types: cipher -- For both input data and output data
0d7f488f0 Stephan Mueller 2014-11-12  390   *		   buffer; ahash -- For output hash destination buf; shash --
0d7f488f0 Stephan Mueller 2014-11-12  391   *		   For output hash destination buf.
0d7f488f0 Stephan Mueller 2014-11-12  392   *		   This is needed on hardware which is flawed by design and
0d7f488f0 Stephan Mueller 2014-11-12  393   *		   cannot pick data from arbitrary addresses.
0d7f488f0 Stephan Mueller 2014-11-12  394   * @cra_priority: Priority of this transformation implementation. In case
0d7f488f0 Stephan Mueller 2014-11-12  395   *		  multiple transformations with same @cra_name are available to
0d7f488f0 Stephan Mueller 2014-11-12  396   *		  the Crypto API, the kernel will use the one with highest

0d7f488f0 Stephan Mueller 2014-11-12  398   * @cra_name: Generic name (usable by multiple implementations) of the
0d7f488f0 Stephan Mueller 2014-11-12  399   *	      transformation algorithm. This is the name of the transformation
0d7f488f0 Stephan Mueller 2014-11-12  400   *	      itself. This field is used by the kernel when looking up the
0d7f488f0 Stephan Mueller 2014-11-12  401   *	      providers of particular transformation.
0d7f488f0 Stephan Mueller 2014-11-12  402   * @cra_driver_name: Unique name of the transformation provider. This is the
0d7f488f0 Stephan Mueller 2014-11-12  403   *		     name of the provider of the transformation. This can be any
0d7f488f0 Stephan Mueller 2014-11-12  404   *		     arbitrary value, but in the usual case, this contains the
0d7f488f0 Stephan Mueller 2014-11-12  405   *		     name of the chip or provider and the name of the
0d7f488f0 Stephan Mueller 2014-11-12  406   *		     transformation algorithm.
0d7f488f0 Stephan Mueller 2014-11-12  407   * @cra_type: Type of the cryptographic transformation. This is a pointer to
0d7f488f0 Stephan Mueller 2014-11-12  408   *	      struct crypto_type, which implements callbacks common for all
12f7c14aa Masanari Iida   2015-06-04  409   *	      transformation types. There are multiple options:

b0d955ba4 Herbert Xu      2015-08-14  411   *	      &crypto_ahash_type, &crypto_rng_type.
0d7f488f0 Stephan Mueller 2014-11-12  412   *	      This field might be empty. In that case, there are no common
0d7f488f0 Stephan Mueller 2014-11-12  413   *	      callbacks. This is the case for: cipher, compress, shash.
0d7f488f0 Stephan Mueller 2014-11-12  414   * @cra_u: Callbacks implementing the transformation. This is a union of
0d7f488f0 Stephan Mueller 2014-11-12  415   *	   multiple structures. Depending on the type of transformation selected
0d7f488f0 Stephan Mueller 2014-11-12  416   *	   by @cra_type and @cra_flags above, the associated structure must be
0d7f488f0 Stephan Mueller 2014-11-12  417   *	   filled with callbacks. This field might be empty. This is the case
0d7f488f0 Stephan Mueller 2014-11-12  418   *	   for ahash, shash.
0d7f488f0 Stephan Mueller 2014-11-12  419   * @cra_init: Initialize the cryptographic transformation object. This function
0d7f488f0 Stephan Mueller 2014-11-12  420   *	      is used to initialize the cryptographic transformation object.
0d7f488f0 Stephan Mueller 2014-11-12  421   *	      This function is called only once at the instantiation time, right
0d7f488f0 Stephan Mueller 2014-11-12  422   *	      after the transformation context was allocated. In case the

0d7f488f0 Stephan Mueller 2014-11-12  424   *	      be handled by software, this function shall check for the precise
0d7f488f0 Stephan Mueller 2014-11-12  425   *	      requirement of the transformation and put any software fallbacks
0d7f488f0 Stephan Mueller 2014-11-12  426   *	      in place.
0d7f488f0 Stephan Mueller 2014-11-12  427   * @cra_exit: Deinitialize the cryptographic transformation object. This is a
0d7f488f0 Stephan Mueller 2014-11-12  428   *	      counterpart to @cra_init, used to remove various changes set in
0d7f488f0 Stephan Mueller 2014-11-12  429   *	      @cra_init.
0d7f488f0 Stephan Mueller 2014-11-12  430   * @cra_module: Owner of this transformation implementation. Set to THIS_MODULE
0d7f488f0 Stephan Mueller 2014-11-12  431   * @cra_list: internally used

This seems like a great set of improvements overall, and I love getting
rid of all that old kernel-doc code.  I will note that it makes a full
htmldocs build take 20-30 seconds longer, which is not entirely
welcome, but so be it.  Someday, I guess, $SOMEBODY should see if there's
some low-hanging optimization fruit there.

Applied, thanks.

Yeah. Well, I used a recursive algorithm, with can be painfull if there
are mang things to parse.

Anyway, I didn't notice it, because there was a major performance regression
that happened recently that it is affecting all my sphinx builds: trying to
compile stuff in parallel with SPHINXOPTS=-j5 is crashing with:

I had to change my build scripts to remove parallel build, with increased
*a lot* the building time. So, right now, I just go out to take a coffee
or two when building documentation, as, without -j (even without this
patch series), is really slow.

If someone wants to look into it, the breakage happened by the time
I upgraded to Fedora 27 and Kernel 4.14 was released. Yet, I'm using
pip for Sphinx.

So, I dunno what's the culprit. I didn't have time yet to investigate.

Thank you!

Hi Mauro, resurrecting an old thread...

So this was a great improvement to documenting nested structs. However,
it looks like it only supports describing the nested structs at the top
level comment, and fails for inline documentation comments.

For example, in v4.16-rc1:

$ scripts/kernel-doc -none drivers/gpu/drm/i915/intel_dpio_phy.c
drivers/gpu/drm/i915/intel_dpio_phy.c:154: warning: Function parameter or member 'channel.port' not described in 'bxt_ddi_phy_info'

The struct in question is:

/**
 * struct bxt_ddi_phy_info - Hold info for a broxton DDI phy
 */
struct bxt_ddi_phy_info {
	/* [some members removed] */

	/**
	 * @channel: struct containing per channel information.
	 */
	struct {
		/**
		 * @port: which port maps to this channel.
		 */
		enum port port;
	} channel[2];
};

Apparently the only way to currently do this is to add channel.port at
the top level:

/**
 * struct bxt_ddi_phy_info - Hold info for a broxton DDI phy
 * @channel.port: which port maps to this channel.
 */

Which is less than perfect if you have everything else described
inline. :(

BR,
Jani.

True. I didn't consider inline comments when I wrote the patch.
We don't use inline doc tags at media. IMO, a single description block
on the top works better, but yeah, it would be very good if it would
support nested structs to also have inlined comments.

Yet, on a quick hack:

diff --git a/scripts/kernel-doc b/scripts/kernel-doc
index fee8952037b1..e2d5cadd8d0b 100755
--- a/scripts/kernel-doc
+++ b/scripts/kernel-doc

 	$declaration_name = $2;
 	my $members = $3;
 
+print "members: $members\n";
+
 	# ignore members marked private:
 	$members =~ s/\/\*\s*private:.*?\/\*\s*public:.*?\*\///gosi;
 	$members =~ s/\/\*\s*private:.*//gosi;

produce:

	$ scripts/kernel-doc -none drivers/gpu/drm/i915/intel_dpio_phy.c
	members:  bool dual_channel; enum dpio_phy rcomp_phy; int reset_delay; u32 pwron_mask; struct { enum port port; }  channel[2]; 
	drivers/gpu/drm/i915/intel_dpio_phy.c:154: warning: Function parameter or member 'channel.port' not described in 'bxt_ddi_phy_info'

So, dump_struct() already receives the struct sanitizes without any comments
inside.

There is a simple fix, though. Make inline comments to accept a dot:

diff --git a/scripts/kernel-doc b/scripts/kernel-doc
index fee8952037b1..06d7f3f2c094 100755

 my $export_symbol = '^\s*EXPORT_SYMBOL(_GPL)?\s*\(\s*(\w+)\s*\)\s*;';

That requires a small change at the inline parameters, though:

 		enum port port;
 	} channel[2];

The alternative would be a way more complex: to teach the code with
starts at:

	If ($inline_doc_state == STATE_INLINE_NAME && /$doc_inline_sect/o) {

About how to handle with inlined structs/enums at inlined comments.

Perhaps it would be slightly more elegant to be able to leave out
"channel." here and deduce that from the context... but the above
matches what you'd write in the higher level struct comment, and
produces the same output. It works and it's really simple. I like it.

Please submit this as a proper patch, with

Submitted. I ended by submitting as a patch series, as, when I
did some tests with the examples, I found that kernel-doc have
issues parsing them.


Thanks,
