kernel-doc nano-HOWTO
=====================
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, some
SGML templates in Documentation/DocBook, 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 "**/".
Kernel-doc comments should be placed just before the function
or data structure being described.
Example kernel-doc function comment:
/**
* foobar() - short function description of foobar
* @arg1: Describe the first argument to foobar.
* @arg2: Describe the second argument to foobar.
* One can provide multiple line descriptions
* for arguments.
*
* A longer description, with more discussion of the function foobar()
* that might be useful to those using or modifying it. Begins with
* empty comment line, and may include additional embedded empty
* comment lines.
*
* The longer description can have multiple paragraphs.
**/
The first line, with the short description, must be on a single line.
The @argument descriptions must begin on the very next line following
this opening short function description line, with no intervening
empty comment lines.
Example kernel-doc data structure comment.
/**
* struct blah - the basic blah structure
* @mem1: describe the first member of struct blah
* @mem2: describe the second member of struct blah,
* perhaps with more lines and words.
*
* Longer description of this structure.
**/
The kernel-doc function comments describe each parameter to the
function, in order, with the @name lines.
The kernel-doc data structure comments describe each structure member
in the data structure, with the @name lines.
The longer description formatting is "reflowed", losing your line
breaks. So presenting carefully formatted lists within these
descriptions won't work so well; derived documentation will lose
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:

pagemap, from the userspace perspective
---------------------------------------
pagemap is a new (as of 2.6.25) set of interfaces in the kernel that allow
userspace programs to examine the page tables and related information by
reading files in /proc.
There are three components to pagemap:
* /proc/pid/pagemap. This file lets a userspace process find out which
physical frame each virtual page is mapped to. It contains one 64-bit
value for each virtual page, containing the following data (from
fs/proc/task_mmu.c, above pagemap_read):
* Bits 0-55 page frame number (PFN) if present
* Bits 0-4 swap type if swapped
* Bits 5-55 swap offset if swapped
* Bits 55-60 page shift (page size = 1<<page shift)
* Bit 61 reserved for future use
* Bit 62 page swapped
* Bit 63 page present
If the page is not present but in swap, then the PFN contains an
encoding of the swap file number and the page's offset into the
swap. Unmapped pages return a null PFN. This allows determining
precisely which pages are mapped (or in swap) and comparing mapped
pages between processes.
Efficient users of this interface will use /proc/pid/maps to
determine which areas of memory are actually mapped and llseek to
skip over unmapped regions.
* /proc/kpagecount. This file contains a 64-bit count of the number of
times each page is mapped, indexed by PFN.
* /proc/kpageflags. This file contains a 64-bit set of flags for each
page, indexed by PFN.
The flags are (from fs/proc/proc_misc, above kpageflags_read):
0. LOCKED
1. ERROR
2. REFERENCED
3. UPTODATE
4. DIRTY
5. LRU
6. ACTIVE
7. SLAB
8. WRITEBACK
9. RECLAIM
10. BUDDY
Using pagemap to do something useful:
The general procedure for using pagemap to find out about a process' memory
usage goes like this:
1. Read /proc/pid/maps to determine which parts of the memory space are
mapped to what.
2. Select the maps you are interested in -- all of them, or a particular
library, or the stack or the heap, etc.
3. Open /proc/pid/pagemap and seek to the pages you would like to examine.
4. Read a u64 for each page from pagemap.
5. Open /proc/kpagecount and/or /proc/kpageflags. For each PFN you just
read, seek to that entry in the file, and read the data you want.
For example, to find the "unique set size" (USS), which is the amount of
memory that a process is using that is not shared with any other process,
you can go through every map in the process, find the PFNs, look those up
in kpagecount, and tally up the number of pages that are only referenced
once.
Other notes:
Reading from any of the files will return -EINVAL if you are not starting
the read on an 8-byte boundary (e.g., if you seeked an odd number of bytes
into the file), or if the size of the read is not a multiple of 8 bytes.
