Input: ads7846 - do not attempt IRQ workaround when deferring probe

When request_irq() returns -EPORBE_DEFER we should abort probe and try again later instead of trying to engage IRQ trigger workaround. Link: https://lore.kernel.org/r/20210910045039.4020199-3-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

+Description:

+		and the zone model of the device if it is indeed zoned.
+		The possible values indicated by zoned are "none" for
+		regular block devices and "host-aware" or "host-managed"
+		for zoned block devices. The characteristics of
+		host-aware and host-managed zoned block devices are
+		described in the ZBC (Zoned Block Commands) and ZAC
+		(Zoned Device ATA Command Set) standards. These standards
+		also define the "drive-managed" zone model. However,
+		since drive-managed zoned block devices do not support
+		zone commands, they will be treated as regular block
+		devices and zoned will report "none".

+		indicates the size in 512B sectors of the RAID volume
+		stripe segment. For a zoned block device, either
+		host-aware or host-managed, chunk_sectors indicates the
+		size of 512B sectors of the zones of the device, with
+		the eventual exception of the last zone of the device
+		which may be smaller.

+Description:
+		Count mode for channel Y. Four count modes are available:

+		for channel Y is used by the count mode where required.
+
+		Normal:
+			Counting is continuous in either direction.
+
+		Range Limit:
+			An upper or lower limit is set, mimicking limit switches
+			in the mechanical counterpart. The upper limit is set to
+			the preset value, while the lower limit is set to 0. The
+			counter freezes at count = preset when counting up, and
+			at count = 0 when counting down. At either of these
+			limits, the counting is resumed only when the count
+			direction is reversed.
+
+		Non-recycle:
+			Counter is disabled whenever a 24-bit count overflow or
+			underflow takes place. The counter is re-enabled when a
+			new count value is loaded to the counter via a preset
+			operation or write to raw.
+
+		Modulo-N:
+			A count boundary is set between 0 and the preset value.
+			The counter is reset to 0 at count = preset when
+			counting up, while the counter is set to the preset
+			value at count = 0 when counting down; the counter does
+			not freeze at the bundary points, but counts
+			continuously throughout.

-Introduction
-============
-
-Always try the latest kernel from kernel.org and build from source. If you are
-not confident in doing that please report the bug to your distribution vendor
-instead of to a kernel developer.
-
-Finding bugs is not always easy. Have a go though. If you can't find it don't
-give up. Report as much as you have found to the relevant maintainer. See
-MAINTAINERS for who that is for the subsystem you have worked on.
-
-Before you submit a bug report read REPORTING-BUGS.
-
-Devices not appearing
-=====================
-
-Often this is caused by udev. Check that first before blaming it on the
-kernel.
-

-Finding using git-bisect
-------------------------
-
-Using the provided tools with git makes finding bugs easy provided the bug is
-reproducible.
-
-Steps to do it:
-- start using git for the kernel source
-- read the man page for git-bisect
-- have fun

-
-[Sat Mar  2 10:32:33 PST 1996 KERNEL_BUG-HOWTO lm@sgi.com (Larry McVoy)]
-
-This is how to track down a bug if you know nothing about kernel hacking.
-It's a brute force approach but it works pretty well.
-
-You need:
-
-        . A reproducible bug - it has to happen predictably (sorry)
-        . All the kernel tar files from a revision that worked to the
-          revision that doesn't
-
-You will then do:
-
-        . Rebuild a revision that you believe works, install, and verify that.
-        . Do a binary search over the kernels to figure out which one
-          introduced the bug.  I.e., suppose 1.3.28 didn't have the bug, but
-          you know that 1.3.69 does.  Pick a kernel in the middle and build
-          that, like 1.3.50.  Build & test; if it works, pick the mid point
-          between .50 and .69, else the mid point between .28 and .50.
-        . You'll narrow it down to the kernel that introduced the bug.  You
-          can probably do better than this but it gets tricky.
-
-        . Narrow it down to a subdirectory
-
-          - Copy kernel that works into "test".  Let's say that 3.62 works,
-            but 3.63 doesn't.  So you diff -r those two kernels and come
-            up with a list of directories that changed.  For each of those
-            directories:
-
-                Copy the non-working directory next to the working directory
-                as "dir.63".
-                One directory at time, try moving the working directory to
-                "dir.62" and mv dir.63 dir"time, try
-
-                        mv dir dir.62
-                        mv dir.63 dir
-                        find dir -name '*.[oa]' -print | xargs rm -f
-
-                And then rebuild and retest.  Assuming that all related
-                changes were contained in the sub directory, this should
-                isolate the change to a directory.
-
-                Problems: changes in header files may have occurred; I've
-                found in my case that they were self explanatory - you may
-                or may not want to give up when that happens.
-
-        . Narrow it down to a file
-
-          - You can apply the same technique to each file in the directory,
-            hoping that the changes in that file are self contained.
-
-        . Narrow it down to a routine
-
-          - You can take the old file and the new file and manually create
-            a merged file that has
-
-                #ifdef VER62
-                routine()
-                {
-                        ...
-                }
-                #else
-                routine()
-                {
-                        ...
-                }
-                #endif
-
-            And then walk through that file, one routine at a time and
-            prefix it with
-
-                #define VER62
-                /* both routines here */
-                #undef VER62
-
-            Then recompile, retest, move the ifdefs until you find the one
-            that makes the difference.
-
-Finally, you take all the info that you have, kernel revisions, bug
-description, the extent to which you have narrowed it down, and pass
-that off to whomever you believe is the maintainer of that section.
-A post to linux.dev.kernel isn't such a bad idea if you've done some
-work to narrow it down.
-
-If you get it down to a routine, you'll probably get a fix in 24 hours.
-
-My apologies to Linus and the other kernel hackers for describing this
-brute force approach, it's hardly what a kernel hacker would do.  However,
-it does work and it lets non-hackers help fix bugs.  And it is cool
-because Linux snapshots will let you do this - something that you can't
-do with vendor supplied releases.
-
-Fixing the bug
-==============
-
-Nobody is going to tell you how to fix bugs. Seriously. You need to work it
-out. But below are some hints on how to use the tools.
-
-To debug a kernel, use objdump and look for the hex offset from the crash
-output to find the valid line of code/assembler. Without debug symbols, you
-will see the assembler code for the routine shown, but if your kernel has
-debug symbols the C code will also be available. (Debug symbols can be enabled
-in the kernel hacking menu of the menu configuration.) For example:
-
-    objdump -r -S -l --disassemble net/dccp/ipv4.o
-
-NB.: you need to be at the top level of the kernel tree for this to pick up
-your C files.
-
-If you don't have access to the code you can also debug on some crash dumps
-e.g. crash dump output as shown by Dave Miller.

-In addition, you can use GDB to figure out the exact file and line
-number of the OOPS from the vmlinux file. If you have
-CONFIG_DEBUG_INFO enabled, you can simply copy the EIP value from the
-OOPS:
-
- EIP:    0060:[<c021e50e>]    Not tainted VLI
-
-And use GDB to translate that to human-readable form:
-
-  gdb vmlinux
-  (gdb) l *0xc021e50e
-
-If you don't have CONFIG_DEBUG_INFO enabled, you use the function
-offset from the OOPS:
-
- EIP is at vt_ioctl+0xda8/0x1482
-
-And recompile the kernel with CONFIG_DEBUG_INFO enabled:
-
-  make vmlinux
-  gdb vmlinux
-  (gdb) p vt_ioctl
-  (gdb) l *(0x<address of vt_ioctl> + 0xda8)
-or, as one command
-  (gdb) l *(vt_ioctl + 0xda8)
-
-If you have a call trace, such as :-
->Call Trace:
-> [<ffffffff8802c8e9>] :jbd:log_wait_commit+0xa3/0xf5
-> [<ffffffff810482d9>] autoremove_wake_function+0x0/0x2e
-> [<ffffffff8802770b>] :jbd:journal_stop+0x1be/0x1ee
-> ...
-this shows the problem in the :jbd: module. You can load that module in gdb
-and list the relevant code.
-  gdb fs/jbd/jbd.ko
-  (gdb) p log_wait_commit
-  (gdb) l *(0x<address> + 0xa3)
-or
-  (gdb) l *(log_wait_commit + 0xa3)
-
-
-Another very useful option of the Kernel Hacking section in menuconfig is
-Debug memory allocations. This will help you see whether data has been
-initialised and not set before use etc. To see the values that get assigned
-with this look at mm/slab.c and search for POISON_INUSE. When using this an
-Oops will often show the poisoned data instead of zero which is the default.
-
-Once you have worked out a fix please submit it upstream. After all open
-source is about sharing what you do and don't you want to be recognised for
-your genius?
-
-Please do read Documentation/SubmittingPatches though to help your code get
-accepted.

-Minimal requerements to compile the Kernel
-++++++++++++++++++++++++++++++++++++++++++
-
-Intro
-=====
-
-This document is designed to provide a list of the minimum levels of
-software necessary to run the 4.x kernels.
-
-This document is originally based on my "Changes" file for 2.0.x kernels
-and therefore owes credit to the same people as that file (Jared Mauch,
-Axel Boldt, Alessandro Sigala, and countless other users all over the
-'net).
-
-Current Minimal Requirements
-****************************
-
-Upgrade to at **least** these software revisions before thinking you've
-encountered a bug!  If you're unsure what version you're currently
-running, the suggested command should tell you.
-
-Again, keep in mind that this list assumes you are already functionally
-running a Linux kernel.  Also, not all tools are necessary on all
-systems; obviously, if you don't have any ISDN hardware, for example,
-you probably needn't concern yourself with isdn4k-utils.

-Kernel compilation
-******************
-
-GCC
----
-
-The gcc version requirements may vary depending on the type of CPU in your
-computer.
-
-Make
-----
-
-You will need GNU make 3.80 or later to build the kernel.
-
-Binutils
---------
-
-Linux on IA-32 has recently switched from using ``as86`` to using ``gas`` for
-assembling the 16-bit boot code, removing the need for ``as86`` to compile
-your kernel.  This change does, however, mean that you need a recent
-release of binutils.
-
-Perl
-----
-
-You will need perl 5 and the following modules: ``Getopt::Long``,
-``Getopt::Std``, ``File::Basename``, and ``File::Find`` to build the kernel.
-
-BC
---
-
-You will need bc to build kernels 3.10 and higher
-
-
-OpenSSL
--------
-
-Module signing and external certificate handling use the OpenSSL program and
-crypto library to do key creation and signature generation.
-
-You will need openssl to build kernels 3.7 and higher if module signing is
-enabled.  You will also need openssl development packages to build kernels 4.3
-and higher.
-
-
-System utilities
-****************
-
-Architectural changes
----------------------
-
-DevFS has been obsoleted in favour of udev
-(http://www.kernel.org/pub/linux/utils/kernel/hotplug/)
-
-32-bit UID support is now in place.  Have fun!
-
-Linux documentation for functions is transitioning to inline
-documentation via specially-formatted comments near their
-definitions in the source.  These comments can be combined with the
-SGML templates in the Documentation/DocBook directory to make DocBook
-files, which can then be converted by DocBook stylesheets to PostScript,
-HTML, PDF files, and several other formats.  In order to convert from
-DocBook format to a format of your choice, you'll need to install Jade as
-well as the desired DocBook stylesheets.
-
-Util-linux
-----------
-
-New versions of util-linux provide ``fdisk`` support for larger disks,
-support new options to mount, recognize more supported partition
-types, have a fdformat which works with 2.4 kernels, and similar goodies.
-You'll probably want to upgrade.
-
-Ksymoops
---------
-
-If the unthinkable happens and your kernel oopses, you may need the
-ksymoops tool to decode it, but in most cases you don't.
-It is generally preferred to build the kernel with ``CONFIG_KALLSYMS`` so
-that it produces readable dumps that can be used as-is (this also
-produces better output than ksymoops).  If for some reason your kernel
-is not build with ``CONFIG_KALLSYMS`` and you have no way to rebuild and
-reproduce the Oops with that option, then you can still decode that Oops
-with ksymoops.
-
-Module-Init-Tools
------------------
-
-A new module loader is now in the kernel that requires ``module-init-tools``
-to use.  It is backward compatible with the 2.4.x series kernels.
-
-Mkinitrd
---------
-
-These changes to the ``/lib/modules`` file tree layout also require that
-mkinitrd be upgraded.
-
-E2fsprogs
----------
-
-The latest version of ``e2fsprogs`` fixes several bugs in fsck and
-debugfs.  Obviously, it's a good idea to upgrade.
-
-JFSutils
---------
-
-The ``jfsutils`` package contains the utilities for the file system.
-The following utilities are available:
-
-- ``fsck.jfs`` - initiate replay of the transaction log, and check
-  and repair a JFS formatted partition.
-
-- ``mkfs.jfs`` - create a JFS formatted partition.
-
-- other file system utilities are also available in this package.
-
-Reiserfsprogs
--------------
-
-The reiserfsprogs package should be used for reiserfs-3.6.x
-(Linux kernels 2.4.x). It is a combined package and contains working
-versions of ``mkreiserfs``, ``resize_reiserfs``, ``debugreiserfs`` and
-``reiserfsck``. These utils work on both i386 and alpha platforms.
-
-Xfsprogs
---------
-
-The latest version of ``xfsprogs`` contains ``mkfs.xfs``, ``xfs_db``, and the
-``xfs_repair`` utilities, among others, for the XFS filesystem.  It is
-architecture independent and any version from 2.0.0 onward should
-work correctly with this version of the XFS kernel code (2.6.0 or
-later is recommended, due to some significant improvements).
-
-PCMCIAutils
------------
-
-PCMCIAutils replaces ``pcmcia-cs``. It properly sets up
-PCMCIA sockets at system startup and loads the appropriate modules
-for 16-bit PCMCIA devices if the kernel is modularized and the hotplug
-subsystem is used.
-
-Quota-tools
------------
-
-Support for 32 bit uid's and gid's is required if you want to use
-the newer version 2 quota format.  Quota-tools version 3.07 and
-newer has this support.  Use the recommended version or newer
-from the table above.
-
-Intel IA32 microcode
---------------------
-
-A driver has been added to allow updating of Intel IA32 microcode,
-accessible as a normal (misc) character device.  If you are not using
-udev you may need to::
-
-  mkdir /dev/cpu
-  mknod /dev/cpu/microcode c 10 184
-  chmod 0644 /dev/cpu/microcode
-
-as root before you can use this.  You'll probably also want to
-get the user-space microcode_ctl utility to use with this.
-
-udev
-----
-
-``udev`` is a userspace application for populating ``/dev`` dynamically with
-only entries for devices actually present. ``udev`` replaces the basic
-functionality of devfs, while allowing persistent device naming for
-devices.
-
-FUSE
-----
-
-Needs libfuse 2.4.0 or later.  Absolute minimum is 2.3.0 but mount
-options ``direct_io`` and ``kernel_cache`` won't work.
-
-Networking
-**********
-
-General changes
----------------
-
-If you have advanced network configuration needs, you should probably
-consider using the network tools from ip-route2.
-
-Packet Filter / NAT
--------------------
-The packet filtering and NAT code uses the same tools like the previous 2.4.x
-kernel series (iptables).  It still includes backwards-compatibility modules
-for 2.2.x-style ipchains and 2.0.x-style ipfwadm.
-
-PPP
----
-
-The PPP driver has been restructured to support multilink and to
-enable it to operate over diverse media layers.  If you use PPP,
-upgrade pppd to at least 2.4.0.
-
-If you are not using udev, you must have the device file /dev/ppp
-which can be made by::
-
-  mknod /dev/ppp c 108 0
-
-as root.
-
-Isdn4k-utils
-------------
-
-Due to changes in the length of the phone number field, isdn4k-utils
-needs to be recompiled or (preferably) upgraded.
-
-NFS-utils
----------
-
-In ancient (2.4 and earlier) kernels, the nfs server needed to know
-about any client that expected to be able to access files via NFS.  This
-information would be given to the kernel by ``mountd`` when the client
-mounted the filesystem, or by ``exportfs`` at system startup.  exportfs
-would take information about active clients from ``/var/lib/nfs/rmtab``.
-
-This approach is quite fragile as it depends on rmtab being correct
-which is not always easy, particularly when trying to implement
-fail-over.  Even when the system is working well, ``rmtab`` suffers from
-getting lots of old entries that never get removed.
-
-With modern kernels we have the option of having the kernel tell mountd
-when it gets a request from an unknown host, and mountd can give
-appropriate export information to the kernel.  This removes the
-dependency on ``rmtab`` and means that the kernel only needs to know about
-currently active clients.
-
-To enable this new functionality, you need to::
-
-  mount -t nfsd nfsd /proc/fs/nfsd
-
-before running exportfs or mountd.  It is recommended that all NFS
-services be protected from the internet-at-large by a firewall where
-that is possible.
-
-mcelog
-------
-
-On x86 kernels the mcelog utility is needed to process and log machine check
-events when ``CONFIG_X86_MCE`` is enabled. Machine check events are errors
-reported by the CPU. Processing them is strongly encouraged.
-
-Kernel documentation
-********************
-
-Sphinx
-------
-
-The ReST markups currently used by the Documentation/ files are meant to be
-built with ``Sphinx`` version 1.2 or upper. If you're desiring to build
-PDF outputs, it is recommended to use version 1.4.6.
-
-.. note::
-
-  Please notice that, for PDF and LaTeX output, you'll also need ``XeLaTeX``
-  version 3.14159265. Depending on the distribution, you may also need
-  to install a series of ``texlive`` packages that provide the minimal
-  set of functionalities required for ``XeLaTex`` to work.
-
-Other tools
------------
-
-In order to produce documentation from DocBook, you'll also need ``xmlto``.
-Please notice, however, that we're currently migrating all documents to use
-``Sphinx``.

-
-Linux kernel coding style
-=========================
-
-This is a short document describing the preferred coding style for the
-linux kernel.  Coding style is very personal, and I won't **force** my
-views on anybody, but this is what goes for anything that I have to be
-able to maintain, and I'd prefer it for most other things too.  Please
-at least consider the points made here.
-
-First off, I'd suggest printing out a copy of the GNU coding standards,
-and NOT read it.  Burn them, it's a great symbolic gesture.
-
-Anyway, here goes:
-
-
-1) Indentation
---------------
-
-Tabs are 8 characters, and thus indentations are also 8 characters.
-There are heretic movements that try to make indentations 4 (or even 2!)
-characters deep, and that is akin to trying to define the value of PI to
-be 3.
-
-Rationale: The whole idea behind indentation is to clearly define where
-a block of control starts and ends.  Especially when you've been looking
-at your screen for 20 straight hours, you'll find it a lot easier to see
-how the indentation works if you have large indentations.
-
-Now, some people will claim that having 8-character indentations makes
-the code move too far to the right, and makes it hard to read on a
-80-character terminal screen.  The answer to that is that if you need
-more than 3 levels of indentation, you're screwed anyway, and should fix
-your program.
-
-In short, 8-char indents make things easier to read, and have the added
-benefit of warning you when you're nesting your functions too deep.
-Heed that warning.
-
-The preferred way to ease multiple indentation levels in a switch statement is
-to align the ``switch`` and its subordinate ``case`` labels in the same column
-instead of ``double-indenting`` the ``case`` labels.  E.g.:
-
-.. code-block:: c
-
-	switch (suffix) {
-	case 'G':
-	case 'g':
-		mem <<= 30;
-		break;
-	case 'M':
-	case 'm':
-		mem <<= 20;
-		break;
-	case 'K':
-	case 'k':
-		mem <<= 10;
-		/* fall through */
-	default:
-		break;
-	}
-
-Don't put multiple statements on a single line unless you have
-something to hide:
-
-.. code-block:: c
-
-	if (condition) do_this;
-	  do_something_everytime;
-
-Don't put multiple assignments on a single line either.  Kernel coding style
-is super simple.  Avoid tricky expressions.
-
-Outside of comments, documentation and except in Kconfig, spaces are never
-used for indentation, and the above example is deliberately broken.
-
-Get a decent editor and don't leave whitespace at the end of lines.
-
-
-2) Breaking long lines and strings
-----------------------------------
-
-Coding style is all about readability and maintainability using commonly
-available tools.
-
-The limit on the length of lines is 80 columns and this is a strongly
-preferred limit.
-
-Statements longer than 80 columns will be broken into sensible chunks, unless
-exceeding 80 columns significantly increases readability and does not hide
-information. Descendants are always substantially shorter than the parent and
-are placed substantially to the right. The same applies to function headers
-with a long argument list. However, never break user-visible strings such as
-printk messages, because that breaks the ability to grep for them.
-
-
-3) Placing Braces and Spaces
-----------------------------
-
-The other issue that always comes up in C styling is the placement of
-braces.  Unlike the indent size, there are few technical reasons to
-choose one placement strategy over the other, but the preferred way, as
-shown to us by the prophets Kernighan and Ritchie, is to put the opening
-brace last on the line, and put the closing brace first, thusly:
-
-.. code-block:: c
-
-	if (x is true) {
-		we do y
-	}
-
-This applies to all non-function statement blocks (if, switch, for,
-while, do).  E.g.:
-
-.. code-block:: c
-
-	switch (action) {
-	case KOBJ_ADD:
-		return "add";
-	case KOBJ_REMOVE:
-		return "remove";
-	case KOBJ_CHANGE:
-		return "change";
-	default:
-		return NULL;
-	}
-
-However, there is one special case, namely functions: they have the
-opening brace at the beginning of the next line, thus:
-
-.. code-block:: c
-
-	int function(int x)
-	{
-		body of function
-	}
-
-Heretic people all over the world have claimed that this inconsistency
-is ...  well ...  inconsistent, but all right-thinking people know that
-(a) K&R are **right** and (b) K&R are right.  Besides, functions are
-special anyway (you can't nest them in C).
-
-Note that the closing brace is empty on a line of its own, **except** in
-the cases where it is followed by a continuation of the same statement,
-ie a ``while`` in a do-statement or an ``else`` in an if-statement, like
-this:
-
-.. code-block:: c
-
-	do {
-		body of do-loop
-	} while (condition);
-
-and
-
-.. code-block:: c
-
-	if (x == y) {
-		..
-	} else if (x > y) {
-		...
-	} else {
-		....
-	}
-
-Rationale: K&R.
-
-Also, note that this brace-placement also minimizes the number of empty
-(or almost empty) lines, without any loss of readability.  Thus, as the
-supply of new-lines on your screen is not a renewable resource (think
-25-line terminal screens here), you have more empty lines to put
-comments on.
-
-Do not unnecessarily use braces where a single statement will do.
-
-.. code-block:: c
-
-	if (condition)
-		action();
-
-and
-
-.. code-block:: none
-
-	if (condition)
-		do_this();
-	else
-		do_that();
-
-This does not apply if only one branch of a conditional statement is a single
-statement; in the latter case use braces in both branches:
-
-.. code-block:: c
-
-	if (condition) {
-		do_this();
-		do_that();
-	} else {
-		otherwise();
-	}
-
-3.1) Spaces
-***********
-
-Linux kernel style for use of spaces depends (mostly) on
-function-versus-keyword usage.  Use a space after (most) keywords.  The
-notable exceptions are sizeof, typeof, alignof, and __attribute__, which look
-somewhat like functions (and are usually used with parentheses in Linux,
-although they are not required in the language, as in: ``sizeof info`` after
-``struct fileinfo info;`` is declared).
-
-So use a space after these keywords::
-
-	if, switch, case, for, do, while
-
-but not with sizeof, typeof, alignof, or __attribute__.  E.g.,
-
-.. code-block:: c
-
-
-	s = sizeof(struct file);
-
-Do not add spaces around (inside) parenthesized expressions.  This example is
-**bad**:
-
-.. code-block:: c
-
-
-	s = sizeof( struct file );
-
-When declaring pointer data or a function that returns a pointer type, the
-preferred use of ``*`` is adjacent to the data name or function name and not
-adjacent to the type name.  Examples:
-
-.. code-block:: c
-
-
-	char *linux_banner;
-	unsigned long long memparse(char *ptr, char **retptr);
-	char *match_strdup(substring_t *s);
-
-Use one space around (on each side of) most binary and ternary operators,
-such as any of these::
-
-	=  +  -  <  >  *  /  %  |  &  ^  <=  >=  ==  !=  ?  :
-
-but no space after unary operators::
-
-	&  *  +  -  ~  !  sizeof  typeof  alignof  __attribute__  defined
-
-no space before the postfix increment & decrement unary operators::
-
-	++  --
-
-no space after the prefix increment & decrement unary operators::
-
-	++  --
-
-and no space around the ``.`` and ``->`` structure member operators.
-
-Do not leave trailing whitespace at the ends of lines.  Some editors with
-``smart`` indentation will insert whitespace at the beginning of new lines as
-appropriate, so you can start typing the next line of code right away.
-However, some such editors do not remove the whitespace if you end up not
-putting a line of code there, such as if you leave a blank line.  As a result,
-you end up with lines containing trailing whitespace.
-
-Git will warn you about patches that introduce trailing whitespace, and can
-optionally strip the trailing whitespace for you; however, if applying a series
-of patches, this may make later patches in the series fail by changing their
-context lines.
-
-
-4) Naming
----------
-
-C is a Spartan language, and so should your naming be.  Unlike Modula-2
-and Pascal programmers, C programmers do not use cute names like
-ThisVariableIsATemporaryCounter.  A C programmer would call that
-variable ``tmp``, which is much easier to write, and not the least more
-difficult to understand.
-
-HOWEVER, while mixed-case names are frowned upon, descriptive names for
-global variables are a must.  To call a global function ``foo`` is a
-shooting offense.
-
-GLOBAL variables (to be used only if you **really** need them) need to
-have descriptive names, as do global functions.  If you have a function
-that counts the number of active users, you should call that
-``count_active_users()`` or similar, you should **not** call it ``cntusr()``.
-
-Encoding the type of a function into the name (so-called Hungarian
-notation) is brain damaged - the compiler knows the types anyway and can
-check those, and it only confuses the programmer.  No wonder MicroSoft
-makes buggy programs.
-
-LOCAL variable names should be short, and to the point.  If you have
-some random integer loop counter, it should probably be called ``i``.
-Calling it ``loop_counter`` is non-productive, if there is no chance of it
-being mis-understood.  Similarly, ``tmp`` can be just about any type of
-variable that is used to hold a temporary value.
-
-If you are afraid to mix up your local variable names, you have another
-problem, which is called the function-growth-hormone-imbalance syndrome.
-See chapter 6 (Functions).
-
-
-5) Typedefs
------------
-
-Please don't use things like ``vps_t``.
-It's a **mistake** to use typedef for structures and pointers. When you see a
-
-.. code-block:: c
-
-
-	vps_t a;
-
-in the source, what does it mean?
-In contrast, if it says
-
-.. code-block:: c
-
-	struct virtual_container *a;
-
-you can actually tell what ``a`` is.
-
-Lots of people think that typedefs ``help readability``. Not so. They are
-useful only for:
-
- (a) totally opaque objects (where the typedef is actively used to **hide**
-     what the object is).
-
-     Example: ``pte_t`` etc. opaque objects that you can only access using
-     the proper accessor functions.
-
-     .. note::
-
-       Opaqueness and ``accessor functions`` are not good in themselves.
-       The reason we have them for things like pte_t etc. is that there
-       really is absolutely **zero** portably accessible information there.
-
- (b) Clear integer types, where the abstraction **helps** avoid confusion
-     whether it is ``int`` or ``long``.
-
-     u8/u16/u32 are perfectly fine typedefs, although they fit into
-     category (d) better than here.
-
-     .. note::
-
-       Again - there needs to be a **reason** for this. If something is
-       ``unsigned long``, then there's no reason to do
-
-	typedef unsigned long myflags_t;
-
-     but if there is a clear reason for why it under certain circumstances
-     might be an ``unsigned int`` and under other configurations might be
-     ``unsigned long``, then by all means go ahead and use a typedef.
-
- (c) when you use sparse to literally create a **new** type for
-     type-checking.
-
- (d) New types which are identical to standard C99 types, in certain
-     exceptional circumstances.
-
-     Although it would only take a short amount of time for the eyes and
-     brain to become accustomed to the standard types like ``uint32_t``,
-     some people object to their use anyway.
-
-     Therefore, the Linux-specific ``u8/u16/u32/u64`` types and their
-     signed equivalents which are identical to standard types are
-     permitted -- although they are not mandatory in new code of your
-     own.
-
-     When editing existing code which already uses one or the other set
-     of types, you should conform to the existing choices in that code.
-
- (e) Types safe for use in userspace.
-
-     In certain structures which are visible to userspace, we cannot
-     require C99 types and cannot use the ``u32`` form above. Thus, we
-     use __u32 and similar types in all structures which are shared
-     with userspace.
-
-Maybe there are other cases too, but the rule should basically be to NEVER
-EVER use a typedef unless you can clearly match one of those rules.
-
-In general, a pointer, or a struct that has elements that can reasonably
-be directly accessed should **never** be a typedef.
-
-
-6) Functions
-------------
-
-Functions should be short and sweet, and do just one thing.  They should
-fit on one or two screenfuls of text (the ISO/ANSI screen size is 80x24,
-as we all know), and do one thing and do that well.
-
-The maximum length of a function is inversely proportional to the
-complexity and indentation level of that function.  So, if you have a
-conceptually simple function that is just one long (but simple)
-case-statement, where you have to do lots of small things for a lot of
-different cases, it's OK to have a longer function.
-
-However, if you have a complex function, and you suspect that a
-less-than-gifted first-year high-school student might not even
-understand what the function is all about, you should adhere to the
-maximum limits all the more closely.  Use helper functions with
-descriptive names (you can ask the compiler to in-line them if you think
-it's performance-critical, and it will probably do a better job of it
-than you would have done).
-
-Another measure of the function is the number of local variables.  They
-shouldn't exceed 5-10, or you're doing something wrong.  Re-think the
-function, and split it into smaller pieces.  A human brain can
-generally easily keep track of about 7 different things, anything more
-and it gets confused.  You know you're brilliant, but maybe you'd like
-to understand what you did 2 weeks from now.
-
-In source files, separate functions with one blank line.  If the function is
-exported, the **EXPORT** macro for it should follow immediately after the
-closing function brace line.  E.g.:
-
-.. code-block:: c
-
-	int system_is_up(void)
-	{
-		return system_state == SYSTEM_RUNNING;
-	}
-	EXPORT_SYMBOL(system_is_up);
-
-In function prototypes, include parameter names with their data types.
-Although this is not required by the C language, it is preferred in Linux
-because it is a simple way to add valuable information for the reader.
-
-
-7) Centralized exiting of functions
------------------------------------
-
-Albeit deprecated by some people, the equivalent of the goto statement is
-used frequently by compilers in form of the unconditional jump instruction.
-
-The goto statement comes in handy when a function exits from multiple
-locations and some common work such as cleanup has to be done.  If there is no
-cleanup needed then just return directly.
-
-Choose label names which say what the goto does or why the goto exists.  An
-example of a good name could be ``out_free_buffer:`` if the goto frees ``buffer``.
-Avoid using GW-BASIC names like ``err1:`` and ``err2:``, as you would have to
-renumber them if you ever add or remove exit paths, and they make correctness
-difficult to verify anyway.
-
-The rationale for using gotos is:
-
-- unconditional statements are easier to understand and follow
-- nesting is reduced
-- errors by not updating individual exit points when making
-  modifications are prevented
-- saves the compiler work to optimize redundant code away ;)
-
-.. code-block:: c
-
-	int fun(int a)
-	{
-		int result = 0;
-		char *buffer;
-
-		buffer = kmalloc(SIZE, GFP_KERNEL);
-		if (!buffer)
-			return -ENOMEM;
-
-		if (condition1) {
-			while (loop1) {
-				...
-			}
-			result = 1;
-			goto out_buffer;
-		}
-		...
-	out_free_buffer:
-		kfree(buffer);
-		return result;
-	}
-
-A common type of bug to be aware of is ``one err bugs`` which look like this:
-
-.. code-block:: c
-
-	err:
-		kfree(foo->bar);
-		kfree(foo);
-		return ret;
-
-The bug in this code is that on some exit paths ``foo`` is NULL.  Normally the
-fix for this is to split it up into two error labels ``err_free_bar:`` and
-``err_free_foo:``:
-
-.. code-block:: c
-
-	 err_free_bar:
-		kfree(foo->bar);
-	 err_free_foo:
-		kfree(foo);
-		return ret;
-
-Ideally you should simulate errors to test all exit paths.
-
-
-8) Commenting
--------------
-
-Comments are good, but there is also a danger of over-commenting.  NEVER
-try to explain HOW your code works in a comment: it's much better to
-write the code so that the **working** is obvious, and it's a waste of
-time to explain badly written code.
-
-Generally, you want your comments to tell WHAT your code does, not HOW.
-Also, try to avoid putting comments inside a function body: if the
-function is so complex that you need to separately comment parts of it,
-you should probably go back to chapter 6 for a while.  You can make
-small comments to note or warn about something particularly clever (or
-ugly), but try to avoid excess.  Instead, put the comments at the head
-of the function, telling people what it does, and possibly WHY it does
-it.
-
-When commenting the kernel API functions, please use the kernel-doc format.
-See the files Documentation/kernel-documentation.rst and scripts/kernel-doc
-for details.
-
-The preferred style for long (multi-line) comments is:
-
-.. code-block:: c
-
-	/*
-	 * This is the preferred style for multi-line
-	 * comments in the Linux kernel source code.
-	 * Please use it consistently.
-	 *
-	 * Description:  A column of asterisks on the left side,
-	 * with beginning and ending almost-blank lines.
-	 */
-
-For files in net/ and drivers/net/ the preferred style for long (multi-line)
-comments is a little different.
-
-.. code-block:: c
-
-	/* The preferred comment style for files in net/ and drivers/net
-	 * looks like this.
-	 *
-	 * It is nearly the same as the generally preferred comment style,
-	 * but there is no initial almost-blank line.
-	 */
-
-It's also important to comment data, whether they are basic types or derived
-types.  To this end, use just one data declaration per line (no commas for
-multiple data declarations).  This leaves you room for a small comment on each
-item, explaining its use.
-
-
-9) You've made a mess of it
----------------------------
-
-That's OK, we all do.  You've probably been told by your long-time Unix
-user helper that ``GNU emacs`` automatically formats the C sources for
-you, and you've noticed that yes, it does do that, but the defaults it
-uses are less than desirable (in fact, they are worse than random
-typing - an infinite number of monkeys typing into GNU emacs would never
-make a good program).
-
-So, you can either get rid of GNU emacs, or change it to use saner
-values.  To do the latter, you can stick the following in your .emacs file:
-
-.. code-block:: none
-
-  (defun c-lineup-arglist-tabs-only (ignored)
-    "Line up argument lists by tabs, not spaces"
-    (let* ((anchor (c-langelem-pos c-syntactic-element))
-           (column (c-langelem-2nd-pos c-syntactic-element))
-           (offset (- (1+ column) anchor))
-           (steps (floor offset c-basic-offset)))
-      (* (max steps 1)
-         c-basic-offset)))
-
-  (add-hook 'c-mode-common-hook
-            (lambda ()
-              ;; Add kernel style
-              (c-add-style
-               "linux-tabs-only"
-               '("linux" (c-offsets-alist
-                          (arglist-cont-nonempty
-                           c-lineup-gcc-asm-reg
-                           c-lineup-arglist-tabs-only))))))
-
-  (add-hook 'c-mode-hook
-            (lambda ()
-              (let ((filename (buffer-file-name)))
-                ;; Enable kernel mode for the appropriate files
-                (when (and filename
-                           (string-match (expand-file-name "~/src/linux-trees")
-                                         filename))
-                  (setq indent-tabs-mode t)
-                  (setq show-trailing-whitespace t)
-                  (c-set-style "linux-tabs-only")))))
-
-This will make emacs go better with the kernel coding style for C
-files below ``~/src/linux-trees``.
-
-But even if you fail in getting emacs to do sane formatting, not
-everything is lost: use ``indent``.
-
-Now, again, GNU indent has the same brain-dead settings that GNU emacs
-has, which is why you need to give it a few command line options.
-However, that's not too bad, because even the makers of GNU indent
-recognize the authority of K&R (the GNU people aren't evil, they are
-just severely misguided in this matter), so you just give indent the
-options ``-kr -i8`` (stands for ``K&R, 8 character indents``), or use
-``scripts/Lindent``, which indents in the latest style.
-
-``indent`` has a lot of options, and especially when it comes to comment
-re-formatting you may want to take a look at the man page.  But
-remember: ``indent`` is not a fix for bad programming.
-
-
-10) Kconfig configuration files
--------------------------------
-
-For all of the Kconfig* configuration files throughout the source tree,
-the indentation is somewhat different.  Lines under a ``config`` definition
-are indented with one tab, while help text is indented an additional two
-spaces.  Example::
-
-  config AUDIT
-	bool "Auditing support"
-	depends on NET
-	help
-	  Enable auditing infrastructure that can be used with another
-	  kernel subsystem, such as SELinux (which requires this for
-	  logging of avc messages output).  Does not do system-call
-	  auditing without CONFIG_AUDITSYSCALL.
-
-Seriously dangerous features (such as write support for certain
-filesystems) should advertise this prominently in their prompt string::
-
-  config ADFS_FS_RW
-	bool "ADFS write support (DANGEROUS)"
-	depends on ADFS_FS
-	...
-
-For full documentation on the configuration files, see the file
-Documentation/kbuild/kconfig-language.txt.
-
-
-11) Data structures
--------------------
-
-Data structures that have visibility outside the single-threaded
-environment they are created and destroyed in should always have
-reference counts.  In the kernel, garbage collection doesn't exist (and
-outside the kernel garbage collection is slow and inefficient), which
-means that you absolutely **have** to reference count all your uses.
-
-Reference counting means that you can avoid locking, and allows multiple
-users to have access to the data structure in parallel - and not having
-to worry about the structure suddenly going away from under them just
-because they slept or did something else for a while.
-
-Note that locking is **not** a replacement for reference counting.
-Locking is used to keep data structures coherent, while reference
-counting is a memory management technique.  Usually both are needed, and
-they are not to be confused with each other.
-
-Many data structures can indeed have two levels of reference counting,
-when there are users of different ``classes``.  The subclass count counts
-the number of subclass users, and decrements the global count just once
-when the subclass count goes to zero.
-
-Examples of this kind of ``multi-level-reference-counting`` can be found in
-memory management (``struct mm_struct``: mm_users and mm_count), and in
-filesystem code (``struct super_block``: s_count and s_active).
-
-Remember: if another thread can find your data structure, and you don't
-have a reference count on it, you almost certainly have a bug.
-
-
-12) Macros, Enums and RTL
--------------------------
-
-Names of macros defining constants and labels in enums are capitalized.
-
-.. code-block:: c
-
-	#define CONSTANT 0x12345
-
-Enums are preferred when defining several related constants.
-
-CAPITALIZED macro names are appreciated but macros resembling functions
-may be named in lower case.
-
-Generally, inline functions are preferable to macros resembling functions.
-
-Macros with multiple statements should be enclosed in a do - while block:
-
-.. code-block:: c
-
-	#define macrofun(a, b, c)			\
-		do {					\
-			if (a == 5)			\
-				do_this(b, c);		\
-		} while (0)
-
-Things to avoid when using macros:
-
-1) macros that affect control flow:
-
-.. code-block:: c
-
-	#define FOO(x)					\
-		do {					\
-			if (blah(x) < 0)		\
-				return -EBUGGERED;	\
-		} while (0)
-
-is a **very** bad idea.  It looks like a function call but exits the ``calling``
-function; don't break the internal parsers of those who will read the code.
-
-2) macros that depend on having a local variable with a magic name:
-
-.. code-block:: c
-
-	#define FOO(val) bar(index, val)
-
-might look like a good thing, but it's confusing as hell when one reads the
-code and it's prone to breakage from seemingly innocent changes.
-
-3) macros with arguments that are used as l-values: FOO(x) = y; will
-bite you if somebody e.g. turns FOO into an inline function.
-
-4) forgetting about precedence: macros defining constants using expressions
-must enclose the expression in parentheses. Beware of similar issues with
-macros using parameters.
-
-.. code-block:: c
-
-	#define CONSTANT 0x4000
-	#define CONSTEXP (CONSTANT | 3)
-
-5) namespace collisions when defining local variables in macros resembling
-functions:
-
-.. code-block:: c
-
-	#define FOO(x)				\
-	({					\
-		typeof(x) ret;			\
-		ret = calc_ret(x);		\
-		(ret);				\
-	})
-
-ret is a common name for a local variable - __foo_ret is less likely
-to collide with an existing variable.
-
-The cpp manual deals with macros exhaustively. The gcc internals manual also
-covers RTL which is used frequently with assembly language in the kernel.
-
-
-13) Printing kernel messages
-----------------------------
-
-Kernel developers like to be seen as literate. Do mind the spelling
-of kernel messages to make a good impression. Do not use crippled
-words like ``dont``; use ``do not`` or ``don't`` instead.  Make the messages
-concise, clear, and unambiguous.
-
-Kernel messages do not have to be terminated with a period.
-
-Printing numbers in parentheses (%d) adds no value and should be avoided.
-
-There are a number of driver model diagnostic macros in <linux/device.h>
-which you should use to make sure messages are matched to the right device
-and driver, and are tagged with the right level:  dev_err(), dev_warn(),
-dev_info(), and so forth.  For messages that aren't associated with a
-particular device, <linux/printk.h> defines pr_notice(), pr_info(),
-pr_warn(), pr_err(), etc.
-
-Coming up with good debugging messages can be quite a challenge; and once
-you have them, they can be a huge help for remote troubleshooting.  However
-debug message printing is handled differently than printing other non-debug
-messages.  While the other pr_XXX() functions print unconditionally,
-pr_debug() does not; it is compiled out by default, unless either DEBUG is
-defined or CONFIG_DYNAMIC_DEBUG is set.  That is true for dev_dbg() also,
-and a related convention uses VERBOSE_DEBUG to add dev_vdbg() messages to
-the ones already enabled by DEBUG.
-
-Many subsystems have Kconfig debug options to turn on -DDEBUG in the
-corresponding Makefile; in other cases specific files #define DEBUG.  And
-when a debug message should be unconditionally printed, such as if it is
-already inside a debug-related #ifdef section, printk(KERN_DEBUG ...) can be
-used.
-
-
-14) Allocating memory
----------------------
-
-The kernel provides the following general purpose memory allocators:
-kmalloc(), kzalloc(), kmalloc_array(), kcalloc(), vmalloc(), and
-vzalloc().  Please refer to the API documentation for further information
-about them.
-
-The preferred form for passing a size of a struct is the following:
-
-.. code-block:: c
-
-	p = kmalloc(sizeof(*p), ...);
-
-The alternative form where struct name is spelled out hurts readability and
-introduces an opportunity for a bug when the pointer variable type is changed
-but the corresponding sizeof that is passed to a memory allocator is not.
-
-Casting the return value which is a void pointer is redundant. The conversion
-from void pointer to any other pointer type is guaranteed by the C programming
-language.
-
-The preferred form for allocating an array is the following:
-
-.. code-block:: c
-
-	p = kmalloc_array(n, sizeof(...), ...);
-
-The preferred form for allocating a zeroed array is the following:
-
-.. code-block:: c
-
-	p = kcalloc(n, sizeof(...), ...);
-
-Both forms check for overflow on the allocation size n * sizeof(...),
-and return NULL if that occurred.
-
-
-15) The inline disease
-----------------------
-
-There appears to be a common misperception that gcc has a magic "make me
-faster" speedup option called ``inline``. While the use of inlines can be
-appropriate (for example as a means of replacing macros, see Chapter 12), it
-very often is not. Abundant use of the inline keyword leads to a much bigger
-kernel, which in turn slows the system as a whole down, due to a bigger
-icache footprint for the CPU and simply because there is less memory
-available for the pagecache. Just think about it; a pagecache miss causes a
-disk seek, which easily takes 5 milliseconds. There are a LOT of cpu cycles
-that can go into these 5 milliseconds.
-
-A reasonable rule of thumb is to not put inline at functions that have more
-than 3 lines of code in them. An exception to this rule are the cases where
-a parameter is known to be a compiletime constant, and as a result of this
-constantness you *know* the compiler will be able to optimize most of your
-function away at compile time. For a good example of this later case, see
-the kmalloc() inline function.
-
-Often people argue that adding inline to functions that are static and used
-only once is always a win since there is no space tradeoff. While this is
-technically correct, gcc is capable of inlining these automatically without
-help, and the maintenance issue of removing the inline when a second user
-appears outweighs the potential value of the hint that tells gcc to do
-something it would have done anyway.
-
-
-16) Function return values and names
-------------------------------------
-
-Functions can return values of many different kinds, and one of the
-most common is a value indicating whether the function succeeded or
-failed.  Such a value can be represented as an error-code integer
-(-Exxx = failure, 0 = success) or a ``succeeded`` boolean (0 = failure,
-non-zero = success).
-
-Mixing up these two sorts of representations is a fertile source of
-difficult-to-find bugs.  If the C language included a strong distinction
-between integers and booleans then the compiler would find these mistakes
-for us... but it doesn't.  To help prevent such bugs, always follow this
-convention::
-
-	If the name of a function is an action or an imperative command,
-	the function should return an error-code integer.  If the name
-	is a predicate, the function should return a "succeeded" boolean.
-
-For example, ``add work`` is a command, and the add_work() function returns 0
-for success or -EBUSY for failure.  In the same way, ``PCI device present`` is
-a predicate, and the pci_dev_present() function returns 1 if it succeeds in
-finding a matching device or 0 if it doesn't.
-
-All EXPORTed functions must respect this convention, and so should all
-public functions.  Private (static) functions need not, but it is
-recommended that they do.
-
-Functions whose return value is the actual result of a computation, rather
-than an indication of whether the computation succeeded, are not subject to
-this rule.  Generally they indicate failure by returning some out-of-range
-result.  Typical examples would be functions that return pointers; they use
-NULL or the ERR_PTR mechanism to report failure.
-
-
-17) Don't re-invent the kernel macros
--------------------------------------
-
-The header file include/linux/kernel.h contains a number of macros that
-you should use, rather than explicitly coding some variant of them yourself.
-For example, if you need to calculate the length of an array, take advantage
-of the macro
-
-.. code-block:: c
-
-	#define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0]))
-
-Similarly, if you need to calculate the size of some structure member, use
-
-.. code-block:: c
-
-	#define FIELD_SIZEOF(t, f) (sizeof(((t*)0)->f))
-
-There are also min() and max() macros that do strict type checking if you
-need them.  Feel free to peruse that header file to see what else is already
-defined that you shouldn't reproduce in your code.
-
-
-18) Editor modelines and other cruft
-------------------------------------
-
-Some editors can interpret configuration information embedded in source files,
-indicated with special markers.  For example, emacs interprets lines marked
-like this:
-
-.. code-block:: c
-
-	-*- mode: c -*-
-
-Or like this:
-
-.. code-block:: c
-
-	/*
-	Local Variables:
-	compile-command: "gcc -DMAGIC_DEBUG_FLAG foo.c"
-	End:
-	*/
-
-Vim interprets markers that look like this:
-
-.. code-block:: c
-
-	/* vim:set sw=8 noet */
-
-Do not include any of these in source files.  People have their own personal
-editor configurations, and your source files should not override them.  This
-includes markers for indentation and mode configuration.  People may use their
-own custom mode, or may have some other magic method for making indentation
-work correctly.
-
-
-19) Inline assembly
--------------------
-
-In architecture-specific code, you may need to use inline assembly to interface
-with CPU or platform functionality.  Don't hesitate to do so when necessary.
-However, don't use inline assembly gratuitously when C can do the job.  You can
-and should poke hardware from C when possible.
-
-Consider writing simple helper functions that wrap common bits of inline
-assembly, rather than repeatedly writing them with slight variations.  Remember
-that inline assembly can use C parameters.
-
-Large, non-trivial assembly functions should go in .S files, with corresponding
-C prototypes defined in C header files.  The C prototypes for assembly
-functions should use ``asmlinkage``.
-
-You may need to mark your asm statement as volatile, to prevent GCC from
-removing it if GCC doesn't notice any side effects.  You don't always need to
-do so, though, and doing so unnecessarily can limit optimization.
-
-When writing a single inline assembly statement containing multiple
-instructions, put each instruction on a separate line in a separate quoted
-string, and end each string except the last with \n\t to properly indent the
-next instruction in the assembly output:
-
-.. code-block:: c
-
-	asm ("magic %reg1, #42\n\t"
-	     "more_magic %reg2, %reg3"
-	     : /* outputs */ : /* inputs */ : /* clobbers */);
-
-
-20) Conditional Compilation
----------------------------
-
-Wherever possible, don't use preprocessor conditionals (#if, #ifdef) in .c
-files; doing so makes code harder to read and logic harder to follow.  Instead,
-use such conditionals in a header file defining functions for use in those .c
-files, providing no-op stub versions in the #else case, and then call those
-functions unconditionally from .c files.  The compiler will avoid generating
-any code for the stub calls, producing identical results, but the logic will
-remain easy to follow.
-
-Prefer to compile out entire functions, rather than portions of functions or
-portions of expressions.  Rather than putting an ifdef in an expression, factor
-out part or all of the expression into a separate helper function and apply the
-conditional to that function.
-
-If you have a function or variable which may potentially go unused in a
-particular configuration, and the compiler would warn about its definition
-going unused, mark the definition as __maybe_unused rather than wrapping it in
-a preprocessor conditional.  (However, if a function or variable *always* goes
-unused, delete it.)
-
-Within code, where possible, use the IS_ENABLED macro to convert a Kconfig
-symbol into a C boolean expression, and use it in a normal C conditional:
-
-.. code-block:: c
-
-	if (IS_ENABLED(CONFIG_SOMETHING)) {
-		...
-	}
-
-The compiler will constant-fold the conditional away, and include or exclude
-the block of code just as with an #ifdef, so this will not add any runtime
-overhead.  However, this approach still allows the C compiler to see the code
-inside the block, and check it for correctness (syntax, types, symbol
-references, etc).  Thus, you still have to use an #ifdef if the code inside the
-block references symbols that will not exist if the condition is not met.
-
-At the end of any non-trivial #if or #ifdef block (more than a few lines),
-place a comment after the #endif on the same line, noting the conditional
-expression used.  For instance:
-
-.. code-block:: c
-
-	#ifdef CONFIG_SOMETHING
-	...
-	#endif /* CONFIG_SOMETHING */

-  <title>Kernel Crypto API Interface Specification</title>
-
-   <sect1><title>Introduction</title>
-
-    <para>
-     The kernel crypto API offers a rich set of cryptographic ciphers as
-     well as other data transformation mechanisms and methods to invoke
-     these. This document contains a description of the API and provides
-     example code.
-    </para>
-
-    <para>
-     To understand and properly use the kernel crypto API a brief
-     explanation of its structure is given. Based on the architecture,
-     the API can be separated into different components. Following the
-     architecture specification, hints to developers of ciphers are
-     provided. Pointers to the API function call  documentation are
-     given at the end.
-    </para>
-
-    <para>
-     The kernel crypto API refers to all algorithms as "transformations".
-     Therefore, a cipher handle variable usually has the name "tfm".
-     Besides cryptographic operations, the kernel crypto API also knows
-     compression transformations and handles them the same way as ciphers.
-    </para>
-
-    <para>
-     The kernel crypto API serves the following entity types:
-
-     <itemizedlist>
-      <listitem>
-       <para>consumers requesting cryptographic services</para>
-      </listitem>
-      <listitem>
-      <para>data transformation implementations (typically ciphers)
-       that can be called by consumers using the kernel crypto
-       API</para>
-      </listitem>
-     </itemizedlist>
-    </para>
-
-    <para>
-     This specification is intended for consumers of the kernel crypto
-     API as well as for developers implementing ciphers. This API
-     specification, however, does not discuss all API calls available
-     to data transformation implementations (i.e. implementations of
-     ciphers and other transformations (such as CRC or even compression
-     algorithms) that can register with the kernel crypto API).
-    </para>
-
-    <para>
-     Note: The terms "transformation" and cipher algorithm are used
-     interchangeably.
-    </para>
-   </sect1>
-
-   <sect1><title>Terminology</title>
-    <para>
-     The transformation implementation is an actual code or interface
-     to hardware which implements a certain transformation with precisely
-     defined behavior.
-    </para>
-
-    <para>
-     The transformation object (TFM) is an instance of a transformation
-     implementation. There can be multiple transformation objects
-     associated with a single transformation implementation. Each of
-     those transformation objects is held by a crypto API consumer or
-     another transformation. Transformation object is allocated when a
-     crypto API consumer requests a transformation implementation.
-     The consumer is then provided with a structure, which contains
-     a transformation object (TFM).
-    </para>
-
-    <para>
-     The structure that contains transformation objects may also be
-     referred to as a "cipher handle". Such a cipher handle is always
-     subject to the following phases that are reflected in the API calls
-     applicable to such a cipher handle:
-    </para>
-
-    <orderedlist>
-     <listitem>
-      <para>Initialization of a cipher handle.</para>
-     </listitem>
-     <listitem>
-      <para>Execution of all intended cipher operations applicable
-      for the handle where the cipher handle must be furnished to
-      every API call.</para>
-     </listitem>
-     <listitem>
-      <para>Destruction of a cipher handle.</para>
-     </listitem>
-    </orderedlist>
-
-    <para>
-     When using the initialization API calls, a cipher handle is
-     created and returned to the consumer. Therefore, please refer
-     to all initialization API calls that refer to the data
-     structure type a consumer is expected to receive and subsequently
-     to use. The initialization API calls have all the same naming
-     conventions of crypto_alloc_*.
-    </para>
-
-    <para>
-     The transformation context is private data associated with
-     the transformation object.

-
-   <sect1><title>Ciphers And Templates</title>
-    <para>
-     The kernel crypto API provides implementations of single block
-     ciphers and message digests. In addition, the kernel crypto API
-     provides numerous "templates" that can be used in conjunction
-     with the single block ciphers and message digests. Templates
-     include all types of block chaining mode, the HMAC mechanism, etc.
-    </para>
-
-    <para>
-     Single block ciphers and message digests can either be directly
-     used by a caller or invoked together with a template to form
-     multi-block ciphers or keyed message digests.
-    </para>
-
-    <para>
-     A single block cipher may even be called with multiple templates.
-     However, templates cannot be used without a single cipher.
-    </para>
-
-    <para>
-     See /proc/crypto and search for "name". For example:
-
-     <itemizedlist>
-      <listitem><para>aes</para></listitem>
-      <listitem><para>ecb(aes)</para></listitem>
-      <listitem><para>cmac(aes)</para></listitem>

-      <listitem><para>hmac(sha1)</para></listitem>
-      <listitem><para>authenc(hmac(sha1),cbc(aes))</para></listitem>
-     </itemizedlist>
-    </para>
-
-    <para>
-     In these examples, "aes" and "sha1" are the ciphers and all
-     others are the templates.
-    </para>
-   </sect1>
-
-   <sect1><title>Synchronous And Asynchronous Operation</title>
-    <para>
-     The kernel crypto API provides synchronous and asynchronous
-     API operations.
-    </para>
-
-    <para>
-     When using the synchronous API operation, the caller invokes
-     a cipher operation which is performed synchronously by the
-     kernel crypto API. That means, the caller waits until the
-     cipher operation completes. Therefore, the kernel crypto API
-     calls work like regular function calls. For synchronous
-     operation, the set of API calls is small and conceptually
-     similar to any other crypto library.
-    </para>
-
-    <para>
-     Asynchronous operation is provided by the kernel crypto API
-     which implies that the invocation of a cipher operation will
-     complete almost instantly. That invocation triggers the
-     cipher operation but it does not signal its completion. Before
-     invoking a cipher operation, the caller must provide a callback
-     function the kernel crypto API can invoke to signal the
-     completion of the cipher operation. Furthermore, the caller
-     must ensure it can handle such asynchronous events by applying
-     appropriate locking around its data. The kernel crypto API
-     does not perform any special serialization operation to protect
-     the caller's data integrity.
-    </para>
-   </sect1>
-
-   <sect1><title>Crypto API Cipher References And Priority</title>
-    <para>
-     A cipher is referenced by the caller with a string. That string
-     has the following semantics:
-
-     <programlisting>
-	template(single block cipher)
-     </programlisting>
-
-     where "template" and "single block cipher" is the aforementioned
-     template and single block cipher, respectively. If applicable,
-     additional templates may enclose other templates, such as
-
-      <programlisting>
-	template1(template2(single block cipher)))
-      </programlisting>
-    </para>
-
-    <para>
-     The kernel crypto API may provide multiple implementations of a
-     template or a single block cipher. For example, AES on newer
-     Intel hardware has the following implementations: AES-NI,
-     assembler implementation, or straight C. Now, when using the
-     string "aes" with the kernel crypto API, which cipher
-     implementation is used? The answer to that question is the
-     priority number assigned to each cipher implementation by the
-     kernel crypto API. When a caller uses the string to refer to a
-     cipher during initialization of a cipher handle, the kernel
-     crypto API looks up all implementations providing an
-     implementation with that name and selects the implementation
-     with the highest priority.
-    </para>
-
-    <para>
-     Now, a caller may have the need to refer to a specific cipher
-     implementation and thus does not want to rely on the
-     priority-based selection. To accommodate this scenario, the
-     kernel crypto API allows the cipher implementation to register
-     a unique name in addition to common names. When using that
-     unique name, a caller is therefore always sure to refer to
-     the intended cipher implementation.
-    </para>
-
-    <para>
-     The list of available ciphers is given in /proc/crypto. However,
-     that list does not specify all possible permutations of
-     templates and ciphers. Each block listed in /proc/crypto may
-     contain the following information -- if one of the components
-     listed as follows are not applicable to a cipher, it is not
-     displayed:
-    </para>
-
-    <itemizedlist>
-     <listitem>
-      <para>name: the generic name of the cipher that is subject
-       to the priority-based selection -- this name can be used by
-       the cipher allocation API calls (all names listed above are
-       examples for such generic names)</para>
-     </listitem>

-    <para>
-     When allocating a cipher handle, the caller only specifies the
-     cipher type. Symmetric ciphers, however, typically support
-     multiple key sizes (e.g. AES-128 vs. AES-192 vs. AES-256).
-     These key sizes are determined with the length of the provided
-     key. Thus, the kernel crypto API does not provide a separate
-     way to select the particular symmetric cipher key size.

-     The mask flag restricts the type of cipher. The only allowed

-    </para>
-
-    <para>
-     When the caller provides a mask and type specification, the
-     caller limits the search the kernel crypto API can perform for
-     a suitable cipher implementation for the given cipher name.
-     That means, even when a caller uses a cipher name that exists
-     during its initialization call, the kernel crypto API may not
-     select it due to the used type and mask field.

-
-    <para>
-     The kernel crypto API has an internal structure where a cipher
-     implementation may use many layers and indirections. This section
-     shall help to clarify how the kernel crypto API uses
-     various components to implement the complete cipher.
-    </para>
-
-    <para>
-     The following subsections explain the internal structure based
-     on existing cipher implementations. The first section addresses

-    <sect2><title>Generic AEAD Cipher Structure</title>
-
-     <para>
-      The following ASCII art decomposes the kernel crypto API layers
-      when using the AEAD cipher with the automated IV generation. The
-      shown example is used by the IPSEC layer.
-     </para>
-
-     <para>
-      For other use cases of AEAD ciphers, the ASCII art applies as
-      well, but the caller may not use the AEAD cipher with a separate
-      IV generator. In this case, the caller must generate the IV.
-     </para>
-
-     <para>
-      The depicted example decomposes the AEAD cipher of GCM(AES) based
-      on the generic C implementations (gcm.c, aes-generic.c, ctr.c,
-      ghash-generic.c, seqiv.c). The generic implementation serves as an
-      example showing the complete logic of the kernel crypto API.
-     </para>
-
-     <para>
-      It is possible that some streamlined cipher implementations (like
-      AES-NI) provide implementations merging aspects which in the view
-      of the kernel crypto API cannot be decomposed into layers any more.
-      In case of the AES-NI implementation, the CTR mode, the GHASH
-      implementation and the AES cipher are all merged into one cipher
-      implementation registered with the kernel crypto API. In this case,
-      the concept described by the following ASCII art applies too. However,
-      the decomposition of GCM into the individual sub-components
-      by the kernel crypto API is not done any more.
-     </para>
-
-     <para>
-      Each block in the following ASCII art is an independent cipher
-      instance obtained from the kernel crypto API. Each block
-      is accessed by the caller or by other blocks using the API functions
-      defined by the kernel crypto API for the cipher implementation type.
-     </para>
-
-     <para>
-      The blocks below indicate the cipher type as well as the specific
-      logic implemented in the cipher.
-     </para>
-
-     <para>
-      The ASCII art picture also indicates the call structure, i.e. who
-      calls which component. The arrows point to the invoked block
-      where the caller uses the API applicable to the cipher type
-      specified for the block.

-      Note, if a cipher implementation requires a proper alignment

-      The kernel crypto API is able to process requests that are unaligned.

-     The concepts of the kernel crypto API visible to kernel space is fully

-     here as well.

-     The interface is provided via socket type using the type AF_ALG.
-     In addition, the setsockopt option type is SOL_ALG. In case the
-     user space header files do not export these flags yet, use the
-     following macros:

-     A cipher is accessed with the same name as done for the in-kernel
-     API calls. This includes the generic vs. unique naming schema for
-     ciphers as well as the enforcement of priorities for generic names.
-    </para>
-
-    <para>
-     To interact with the kernel crypto API, a socket must be
-     created by the user space application. User space invokes the cipher
-     operation with the send()/write() system call family. The result of the
-     cipher operation is obtained with the read()/recv() system call family.
-    </para>

-   <sect1><title>In-place Cipher operation</title>
-    <para>
-     Just like the in-kernel operation of the kernel crypto API, the user
-     space interface allows the cipher operation in-place. That means that
-     the input buffer used for the send/write system call and the output
-     buffer used by the read/recv system call may be one and the same.
-     This is of particular interest for symmetric cipher operations where a
-     copying of the output data to its final destination can be avoided.

-    <para>
-     If a consumer on the other hand wants to maintain the plaintext and
-     the ciphertext in different memory locations, all a consumer needs
-     to do is to provide different memory pointers for the encryption and
-     decryption operation.
-    </para>
-   </sect1>
-
-   <sect1><title>Message Digest API</title>
-    <para>
-     The message digest type to be used for the cipher operation is
-     selected when invoking the bind syscall. bind requires the caller
-     to provide a filled struct sockaddr data structure. This data
-     structure must be filled as follows:

-struct sockaddr_alg sa = {

-	.salg_name = "sha1" /* this is the cipher name */
-};
-    </programlisting>
-
-    <para>
-     The salg_type value "hash" applies to message digests and keyed
-     message digests. Though, a keyed message digest is referenced by
-     the appropriate salg_name. Please see below for the setsockopt
-     interface that explains how the key can be set for a keyed message
-     digest.
-    </para>
-
-    <para>
-     Using the send() system call, the application provides the data that
-     should be processed with the message digest. The send system call
-     allows the following flags to be specified:

-
-    <itemizedlist>
-     <listitem>
-      <para>
-       MSG_MORE: If this flag is set, the send system call acts like a
-       message digest update function where the final hash is not

-    </para>
-
-    <para>
-     In order to set a message digest key, the calling application must use
-     the setsockopt() option of ALG_SET_KEY. If the key is not set the HMAC
-     operation is performed without the initial HMAC state change caused by

-     /proc/crypto for the selected cipher.
-    </para>
-
-    <para>
-     With the recv() system call, the application can read the result of
-     the cipher operation from the kernel crypto API. The output buffer
-     must be at least as large as defined with the memory structure below.

-     </para>
-

-      </listitem>
-     </itemizedlist>
-
-     <para>
-      The sizes of the AAD and the authentication tag are provided with
-      the sendmsg and setsockopt calls (see there). As the kernel knows
-      the size of the entire data stream, the kernel is now able to
-      calculate the right offsets of the data components in the data
-      stream.
-     </para>
-

-    <para>
-     Again, the operation is very similar to the other APIs.
-     During initialization, the struct sockaddr data structure must be
-     filled as follows:
-    </para>
-
-    <programlisting>
-struct sockaddr_alg sa = {
-	.salg_family = AF_ALG,
-	.salg_type = "rng", /* this selects the symmetric cipher */
-	.salg_name = "drbg_nopr_sha256" /* this is the cipher name */
-};
-    </programlisting>
-
-    <para>
-     Depending on the RNG type, the RNG must be seeded. The seed is provided
-     using the setsockopt interface to set the key. For example, the
-     ansi_cprng requires a seed. The DRBGs do not require a seed, but
-     may be seeded.
-    </para>
-
-    <para>
-     Using the read()/recvmsg() system calls, random numbers can be obtained.
-     The kernel generates at most 128 bytes in one call. If user space
-     requires more data, multiple calls to read()/recvmsg() must be made.
-    </para>
-
-    <para>
-     WARNING: The user space caller may invoke the initially mentioned
-     accept system call multiple times. In this case, the returned file
-     descriptors have the same state.
-    </para>
-
-   </sect1>
-
-   <sect1><title>Zero-Copy Interface</title>
-    <para>
-     In addition to the send/write/read/recv system call family, the AF_ALG
-     interface can be accessed with the zero-copy interface of splice/vmsplice.
-     As the name indicates, the kernel tries to avoid a copy operation into
-     kernel space.
-    </para>
-
-    <para>
-     The zero-copy operation requires data to be aligned at the page boundary.
-     Non-aligned data can be used as well, but may require more operations of
-     the kernel which would defeat the speed gains obtained from the zero-copy
-     interface.
-    </para>
-
-    <para>
-     The system-interent limit for the size of one zero-copy operation is
-     16 pages. If more data is to be sent to AF_ALG, user space must slice
-     the input into segments with a maximum size of 16 pages.
-    </para>
-
-    <para>
-     Zero-copy can be used with the following code example (a complete working
-     example is provided with libkcapi):
-    </para>
-
-    <programlisting>
-int pipes[2];
-
-pipe(pipes);
-/* input data in iov */
-vmsplice(pipes[1], iov, iovlen, SPLICE_F_GIFT);
-/* opfd is the file descriptor returned from accept() system call */
-splice(pipes[0], NULL, opfd, NULL, ret, 0);
-read(opfd, out, outlen);

-
-   </sect1>
-
-   <sect1><title>Setsockopt Interface</title>
-    <para>
-     In addition to the read/recv and send/write system call handling
-     to send and retrieve data subject to the cipher operation, a consumer
-     also needs to set the additional information for the cipher operation.
-     This additional information is set using the setsockopt system call
-     that must be invoked with the file descriptor of the open cipher
-     (i.e. the file descriptor returned by the accept system call).
-    </para>
-
-    <para>
-     Each setsockopt invocation must use the level SOL_ALG.
-    </para>

-    Please note that the kernel crypto API contains the AEAD givcrypt
-    API (crypto_aead_giv* and aead_givcrypt_* function calls in
-    include/crypto/aead.h). This API is obsolete and will be removed
-    in the future. To obtain the functionality of an AEAD cipher with
-    internal IV generation, use the IV generator as a regular cipher.
-    For example, rfc4106(gcm(aes)) is the AEAD cipher with external
-    IV generation and seqniv(rfc4106(gcm(aes))) implies that the kernel
-    crypto API generates the IV. Different IV generators are available.

-    </para>
-    <para>
-      debugobjects is not changing the data structure of the real

-    <title>Howto use debugobjects</title>
-    <para>
-      A kernel subsystem needs to provide a data structure which
-      describes the object type and add calls into the debug code at
-      appropriate places. The data structure to describe the object
-      type needs at minimum the name of the object type. Optional
-      functions can and should be provided to fixup detected problems
-      so the kernel can continue to work and the debug information can
-      be retrieved from a live system instead of hard core debugging
-      with serial consoles and stack trace transcripts from the
-      monitor.
-    </para>
-    <para>
-      The debug calls provided by debugobjects are:
-      <itemizedlist>
-	<listitem><para>debug_object_init</para></listitem>
-	<listitem><para>debug_object_init_on_stack</para></listitem>
-	<listitem><para>debug_object_activate</para></listitem>

-	<listitem><para>debug_object_free</para></listitem>
-	<listitem><para>debug_object_assert_init</para></listitem>
-      </itemizedlist>
-      Each of these functions takes the address of the real object and
-      a pointer to the object type specific debug description
-      structure.
-    </para>
-    <para>
-      Each detected error is reported in the statistics and a limited
-      number of errors are printk'ed including a full stack trace.
-    </para>
-    <para>
-      The statistics are available via /sys/kernel/debug/debug_objects/stats.
-      They provide information about the number of warnings and the
-      number of successful fixups along with information about the
-      usage of the internal tracking objects and the state of the
-      internal tracking objects pool.

-     Tracepoints are static probe points that are located in strategic points
-     throughout the kernel. 'Probes' register/unregister with tracepoints
-     via a callback mechanism. The 'probes' are strictly typed functions that
-     are passed a unique set of parameters defined by each tracepoint.

-
-   <para>
-     From this simple callback mechanism, 'probes' can be used to profile, debug,

-     Tracepoints are defined in a number of header files via various macros. Thus,

+<title>Generic Hyper-V UIO driver</title>
+	<para>
+	The generic driver is a kernel module named uio_hv_generic.
+	It supports devices on the Hyper-V VMBus similar to uio_pci_generic
+	on PCI bus.
+	</para>
+
+<sect1 id="uio_hv_generic_binding">
+<title>Making the driver recognize the device</title>
+	<para>
+Since the driver does not declare any device GUID's, it will not get loaded
+automatically and will not automatically bind to any devices, you must load it
+and allocate id to the driver yourself. For example, to use the network device
+GUID:
+	<programlisting>
+ modprobe uio_hv_generic
+ echo &quot;f8615163-df3e-46c5-913f-f2d2f965ed0e&quot; &gt; /sys/bus/vmbus/drivers/uio_hv_generic/new_id
+	</programlisting>
+	</para>
+	<para>
+If there already is a hardware specific kernel driver for the device, the
+generic driver still won't bind to it, in this case if you want to use the
+generic driver (why would you?) you'll have to manually unbind the hardware
+specific driver and bind the generic driver, like this:
+	<programlisting>
+	  echo -n vmbus-ed963694-e847-4b2a-85af-bc9cfc11d6f3 &gt; /sys/bus/vmbus/drivers/hv_netvsc/unbind
+	  echo -n vmbus-ed963694-e847-4b2a-85af-bc9cfc11d6f3 &gt; /sys/bus/vmbus/drivers/uio_hv_generic/bind
+	</programlisting>
+	</para>
+	<para>
+You can verify that the device has been bound to the driver
+by looking for it in sysfs, for example like the following:
+	<programlisting>
+    ls -l /sys/bus/vmbus/devices/vmbus-ed963694-e847-4b2a-85af-bc9cfc11d6f3/driver
+	</programlisting>
+Which if successful should print
+	<programlisting>
+  .../vmbus-ed963694-e847-4b2a-85af-bc9cfc11d6f3/driver -&gt; ../../../bus/vmbus/drivers/uio_hv_generic
+	</programlisting>
+	</para>
+</sect1>
+
+<sect1 id="uio_hv_generic_internals">
+<title>Things to know about uio_hv_generic</title>
+	<para>
+On each interrupt, uio_hv_generic sets the Interrupt Disable bit.
+This prevents the device from generating further interrupts
+until the bit is cleared. The userspace driver should clear this
+bit before blocking and waiting for more interrupts.

-    <title>Introduction to USB on Linux</title>
-
-    <para>A Universal Serial Bus (USB) is used to connect a host,
-    such as a PC or workstation, to a number of peripheral
-    devices.  USB uses a tree structure, with the host as the
-    root (the system's master), hubs as interior nodes, and
-    peripherals as leaves (and slaves).
-    Modern PCs support several such trees of USB devices, usually
-    one USB 2.0 tree (480 Mbit/sec each) with
-    a few USB 1.1 trees (12 Mbit/sec each) that are used when you
-    connect a USB 1.1 device directly to the machine's "root hub".
-    </para>
-
-    <para>That master/slave asymmetry was designed-in for a number of
-    reasons, one being ease of use.  It is not physically possible to
-    assemble (legal) USB cables incorrectly:  all upstream "to the host"
-    connectors are the rectangular type (matching the sockets on
-    root hubs), and all downstream connectors are the squarish type
-    (or they are built into the peripheral).
-    Also, the host software doesn't need to deal with distributed
-    auto-configuration since the pre-designated master node manages all that.
-    And finally, at the electrical level, bus protocol overhead is reduced by
-    eliminating arbitration and moving scheduling into the host software.
-    </para>
-
-    <para>USB 1.0 was announced in January 1996 and was revised
-    as USB 1.1 (with improvements in hub specification and
-    support for interrupt-out transfers) in September 1998.
-    USB 2.0 was released in April 2000, adding high-speed
-    transfers and transaction-translating hubs (used for USB 1.1
-    and 1.0 backward compatibility).
-    </para>
-
-    <para>Kernel developers added USB support to Linux early in the 2.2 kernel
-    series, shortly before 2.3 development forked.  Updates from 2.3 were
-    regularly folded back into 2.2 releases, which improved reliability and
-    brought <filename>/sbin/hotplug</filename> support as well more drivers.
-    Such improvements were continued in the 2.5 kernel series, where they added
-    USB 2.0 support, improved performance, and made the host controller drivers
-    (HCDs) more consistent.  They also simplified the API (to make bugs less
-    likely) and added internal "kerneldoc" documentation.
-    </para>
-
-    <para>Linux can run inside USB devices as well as on
-    the hosts that control the devices.
-    But USB device drivers running inside those peripherals
-    don't do the same things as the ones running inside hosts,
-    so they've been given a different name:
-    <emphasis>gadget drivers</emphasis>.
-    This document does not cover gadget drivers.

-    <title>USB Host-Side API Model</title>
-
-    <para>Host-side drivers for USB devices talk to the "usbcore" APIs.
-    There are two.  One is intended for
-    <emphasis>general-purpose</emphasis> drivers (exposed through
-    driver frameworks), and the other is for drivers that are
-    <emphasis>part of the core</emphasis>.
-    Such core drivers include the <emphasis>hub</emphasis> driver
-    (which manages trees of USB devices) and several different kinds
-    of <emphasis>host controller drivers</emphasis>,
-    which control individual busses.
-    </para>
-
-    <para>The device model seen by USB drivers is relatively complex.
-    </para>
-     
-    <itemizedlist>
-
-	<listitem><para>USB supports four kinds of data transfers
-	(control, bulk, interrupt, and isochronous).  Two of them (control
-	and bulk) use bandwidth as it's available,
-	while the other two (interrupt and isochronous)
-	are scheduled to provide guaranteed bandwidth.
-	</para></listitem>
-
-	<listitem><para>The device description model includes one or more
-	"configurations" per device, only one of which is active at a time.
-	Devices that are capable of high-speed operation must also support
-	full-speed configurations, along with a way to ask about the
-	"other speed" configurations which might be used.
-	</para></listitem>
-
-	<listitem><para>Configurations have one or more "interfaces", each
-	of which may have "alternate settings".  Interfaces may be
-	standardized by USB "Class" specifications, or may be specific to
-	a vendor or device.</para>
-
-	<para>USB device drivers actually bind to interfaces, not devices.
-	Think of them as "interface drivers", though you
-	may not see many devices where the distinction is important.
-	<emphasis>Most USB devices are simple, with only one configuration,
-	one interface, and one alternate setting.</emphasis>
-	</para></listitem>
-
-	<listitem><para>Interfaces have one or more "endpoints", each of
-	which supports one type and direction of data transfer such as
-	"bulk out" or "interrupt in".  The entire configuration may have
-	up to sixteen endpoints in each direction, allocated as needed
-	among all the interfaces.
-	</para></listitem>
-
-	<listitem><para>Data transfer on USB is packetized; each endpoint
-	has a maximum packet size.
-	Drivers must often be aware of conventions such as flagging the end
-	of bulk transfers using "short" (including zero length) packets.
-	</para></listitem>
-
-	<listitem><para>The Linux USB API supports synchronous calls for
-	control and bulk messages.
-	It also supports asynchronous calls for all kinds of data transfer,
-	using request structures called "URBs" (USB Request Blocks).
-	</para></listitem>
-
-    </itemizedlist>
-
-    <para>Accordingly, the USB Core API exposed to device drivers
-    covers quite a lot of territory.  You'll probably need to consult
-    the USB 2.0 specification, available online from www.usb.org at
-    no cost, as well as class or device specifications.
-    </para>
-
-    <para>The only host-side drivers that actually touch hardware
-    (reading/writing registers, handling IRQs, and so on) are the HCDs.
-    In theory, all HCDs provide the same functionality through the same
-    API.  In practice, that's becoming more true on the 2.5 kernels,
-    but there are still differences that crop up especially with
-    fault handling.  Different controllers don't necessarily report
-    the same aspects of failures, and recovery from faults (including
-    software-induced ones like unlinking an URB) isn't yet fully
-    consistent.
-    Device driver authors should make a point of doing disconnect
-    testing (while the device is active) with each different host
-    controller driver, to make sure drivers don't have bugs of
-    their own as well as to make sure they aren't relying on some
-    HCD-specific behavior.
-    (You will need external USB 1.1 and/or
-    USB 2.0 hubs to perform all those tests.)

-
-<chapter id="hostside"><title>Host-Side Data Types and Macros</title>
-
-    <para>The host side API exposes several layers to drivers, some of
-    which are more necessary than others.
-    These support lifecycle models for host side drivers
-    and devices, and support passing buffers through usbcore to
-    some HCD that performs the I/O for the device driver.
-    </para>

-
-!Iinclude/linux/usb.h
-
-    </chapter>
-
-    <chapter id="usbcore"><title>USB Core APIs</title>
-
-    <para>There are two basic I/O models in the USB API.
-    The most elemental one is asynchronous:  drivers submit requests
-    in the form of an URB, and the URB's completion callback
-    handle the next step.
-    All USB transfer types support that model, although there
-    are special cases for control URBs (which always have setup
-    and status stages, but may not have a data stage) and
-    isochronous URBs (which allow large packets and include
-    per-packet fault reports).
-    Built on top of that is synchronous API support, where a
-    driver calls a routine that allocates one or more URBs,
-    submits them, and waits until they complete.
-    There are synchronous wrappers for single-buffer control
-    and bulk transfers (which are awkward to use in some
-    driver disconnect scenarios), and for scatterlist based
-    streaming i/o (bulk or interrupt).
-    </para>
-
-    <para>USB drivers need to provide buffers that can be
-    used for DMA, although they don't necessarily need to
-    provide the DMA mapping themselves.
-    There are APIs to use used when allocating DMA buffers,
-    which can prevent use of bounce buffers on some systems.
-    In some cases, drivers may be able to rely on 64bit DMA
-    to eliminate another kind of bounce buffer.

-    <chapter id="hcd"><title>Host Controller APIs</title>
-
-    <para>These APIs are only for use by host controller drivers,
-    most of which implement standard register interfaces such as
-    EHCI, OHCI, or UHCI.
-    UHCI was one of the first interfaces, designed by Intel and
-    also used by VIA; it doesn't do much in hardware.
-    OHCI was designed later, to have the hardware do more work
-    (bigger transfers, tracking protocol state, and so on).
-    EHCI was designed with USB 2.0; its design has features that
-    resemble OHCI (hardware does much more work) as well as
-    UHCI (some parts of ISO support, TD list processing).
-    </para>
-
-    <para>There are host controllers other than the "big three",
-    although most PCI based controllers (and a few non-PCI based
-    ones) use one of those interfaces.
-    Not all host controllers use DMA; some use PIO, and there
-    is also a simulator.
-    </para>
-
-    <para>The same basic APIs are available to drivers for all
-    those controllers.  
-    For historical reasons they are in two layers:
-    <structname>struct usb_bus</structname> is a rather thin
-    layer that became available in the 2.2 kernels, while
-    <structname>struct usb_hcd</structname> is a more featureful
-    layer (available in later 2.4 kernels and in 2.5) that
-    lets HCDs share common code, to shrink driver size
-    and significantly reduce hcd-specific behaviors.

-
-	    <para>Such a driver first needs to find a device file
-	    for a device it knows how to handle.
-	    Maybe it was told about it because a
-	    <filename>/sbin/hotplug</filename> event handling agent
-	    chose that driver to handle the new device.
-	    Or maybe it's an application that scans all the
-	    /proc/bus/usb device files, and ignores most devices.
-	    In either case, it should <function>read()</function> all
-	    the descriptors from the device file,
-	    and check them against what it knows how to handle.
-	    It might just reject everything except a particular
-	    vendor and product ID, or need a more complex policy.
-	    </para>
-
-	    <para>Never assume there will only be one such device
-	    on the system at a time!
-	    If your code can't handle more than one device at
-	    a time, at least detect when there's more than one, and
-	    have your users choose which device to use.
-	    </para>
-
-	    <para>Once your user mode driver knows what device to use,
-	    it interacts with it in either of two styles.
-	    The simple style is to make only control requests; some
-	    devices don't need more complex interactions than those.
-	    (An example might be software using vendor-specific control
-	    requests for some initialization or configuration tasks,
-	    with a kernel driver for the rest.)
-	    </para>
-
-	    <para>More likely, you need a more complex style driver:
-	    one using non-control endpoints, reading or writing data
-	    and claiming exclusive use of an interface.
-	    <emphasis>Bulk</emphasis> transfers are easiest to use,
-	    but only their sibling <emphasis>interrupt</emphasis> transfers 
-	    work with low speed devices.
-	    Both interrupt and <emphasis>isochronous</emphasis> transfers
-	    offer service guarantees because their bandwidth is reserved.
-	    Such "periodic" transfers are awkward to use through usbfs,
-	    unless you're using the asynchronous calls.  However, interrupt
-	    transfers can also be used in a synchronous "one shot" style.
-	    </para>
-
-	    <para>Your user-mode driver should never need to worry

-

-    <para>
-      This document describes how to write an
-      <ulink url="http://www.alsa-project.org/"><citetitle>
-      ALSA (Advanced Linux Sound Architecture)</citetitle></ulink>
-      driver. The document focuses mainly on PCI soundcards.
-      In the case of other device types, the API might
-      be different, too. However, at least the ALSA kernel API is
-      consistent, and therefore it would be still a bit help for
-      writing them.
-    </para>
-
-    <para>
-    This document targets people who already have enough
-    C language skills and have basic linux kernel programming
-    knowledge.  This document doesn't explain the general
-    topic of linux kernel coding and doesn't cover low-level
-    driver implementation details. It only describes
-    the standard way to write a PCI sound driver on ALSA.
-    </para>
-
-    <para>
-      If you are already familiar with the older ALSA ver.0.5.x API, you
-    can check the drivers such as <filename>sound/pci/es1938.c</filename> or
-    <filename>sound/pci/maestro3.c</filename> which have also almost the same
-    code-base in the ALSA 0.5.x tree, so you can compare the differences.

-      This document is still a draft version. Any feedback and

-      <para>
-        The ALSA drivers are provided in two ways.
-      </para>
-
-      <para>
-        One is the trees provided as a tarball or via cvs from the
-      ALSA's ftp site, and another is the 2.6 (or later) Linux kernel
-      tree. To synchronize both, the ALSA driver tree is split into
-      two different trees: alsa-kernel and alsa-driver. The former
-      contains purely the source code for the Linux 2.6 (or later)
-      tree. This tree is designed only for compilation on 2.6 or
-      later environment. The latter, alsa-driver, contains many subtle
-      files for compiling ALSA drivers outside of the Linux kernel tree,
-      wrapper functions for older 2.2 and 2.4 kernels, to adapt the latest kernel API,
-      and additional drivers which are still in development or in
-      tests.  The drivers in alsa-driver tree will be moved to
-      alsa-kernel (and eventually to the 2.6 kernel tree) when they are
-      finished and confirmed to work fine.
-      </para>
-
-      <para>
-        The file tree structure of ALSA driver is depicted below. Both
-        alsa-kernel and alsa-driver have almost the same file
-        structure, except for <quote>core</quote> directory. It's
-        named as <quote>acore</quote> in alsa-driver tree.

-        This is the place for the public header files of ALSA drivers,

-        This directory contains code shared among different drivers
-      on different architectures.  They are hence supposed not to be
-      architecture-specific.
-      For example, the dummy pcm driver and the serial MIDI
-      driver are found in this directory. In the sub-directories,

-
-      <para>
-        Although there is a standard i2c layer on Linux, ALSA has its
-      own i2c code for some cards, because the soundcard needs only a

-        The allocation of I/O ports and irqs is done via standard kernel
-      functions. Unlike ALSA ver.0.5.x., there are no helpers for
-      that. And these resources must be released in the destructor
-      function (see below). Also, on ALSA 0.9.x, you don't need to
-      allocate (pseudo-)DMA for PCI like in ALSA 0.5.x.
-      </para>
-
-      <para>
-        Now assume that the PCI device has an I/O port with 8 bytes
-        and an interrupt. Then struct <structname>mychip</structname> will have the

-
-      <para>
-        For an I/O port (and also a memory region), you need to have
-      the resource pointer for the standard resource management. For
-      an irq, you have to keep only the irq number (integer). But you
-      need to initialize this number as -1 before actual allocation,
-      since irq 0 is valid. The port address and its resource pointer
-      can be initialized as null by
-      <function>kzalloc()</function> automatically, so you
-      don't have to take care of resetting them. 
-      </para>
-
-      <para>
-        The allocation of an I/O port is done like this:

-        It will reserve the I/O port region of 8 bytes of the given

-      released via <function>kfree()</function>, but there is a
-      problem with this. This issue will be explained later.
-      </para>
-
-      <para>
-        The allocation of an interrupt source is done like this:

-        <informalexample>
-          <programlisting>
-<![CDATA[

-          </programlisting>

-      interrupt handler defined <link
-      linkend="pcm-interface-interrupt-handler"><citetitle>later</citetitle></link>.
-      Note that chip-&gt;irq should be defined
-      only when <function>request_irq()</function> succeeded.
-      </para>
-
-      <para>
-      On the PCI bus, interrupts can be shared. Thus,
-      <constant>IRQF_SHARED</constant> is used as the interrupt flag of
-      <function>request_irq()</function>. 
-      </para>
-
-      <para>
-        The last argument of <function>request_irq()</function> is the
-      data pointer passed to the interrupt handler. Usually, the
-      chip-specific record is used for that, but you can use what you
-      like, too. 
-      </para>
-
-      <para>
-        I won't give details about the interrupt handler at this
-        point, but at least its appearance can be explained now. The
-        interrupt handler looks usually like the following: 
-
-        <informalexample>
-          <programlisting>
-<![CDATA[
-  static irqreturn_t snd_mychip_interrupt(int irq, void *dev_id)

-        </informalexample>
-      </para>
-
-      <para>
-        Now let's write the corresponding destructor for the resources
-      above. The role of destructor is simple: disable the hardware
-      (if already activated) and release the resources. So far, we
-      have no hardware part, so the disabling code is not written here. 
-      </para>
-
-      <para>
-        To release the resources, the <quote>check-and-release</quote>
-        method is a safer way. For the interrupt, do like this: 
-
-        <informalexample>
-          <programlisting>
-<![CDATA[
-  if (chip->irq >= 0)
-          free_irq(chip->irq, chip);
-]]>
-          </programlisting>
-        </informalexample>
-
-        Since the irq number can start from 0, you should initialize
-        chip-&gt;irq with a negative value (e.g. -1), so that you can
-        check the validity of the irq number as above.
-      </para>
-
-      <para>
-        When you requested I/O ports or memory regions via
-	<function>pci_request_region()</function> or
-	<function>pci_request_regions()</function> like in this example,
-	release the resource(s) using the corresponding function,
-	<function>pci_release_region()</function> or
-	<function>pci_release_regions()</function>.

-      </para>
-
-      <para>
-	When you requested manually via <function>request_region()</function>
-	or <function>request_mem_region</function>, you can release it via
-	<function>release_resource()</function>.  Suppose that you keep
-	the resource pointer returned from <function>request_region()</function>
-	in chip-&gt;res_port, the release procedure looks like:
-
-        <informalexample>
-          <programlisting>

-      before the end.
-      </para>
-
-      <para>
-        And finally, release the chip-specific record.
-
-        <informalexample>
-          <programlisting>

-
-      <para>
-      We didn't implement the hardware disabling part in the above.
-      If you need to do this, please note that the destructor may be
-      called even before the initialization of the chip is completed.
-      It would be better to have a flag to skip hardware disabling
-      if the hardware was not initialized yet.
-      </para>
-
-      <para>
-      When the chip-data is assigned to the card using
-      <function>snd_device_new()</function> with
-      <constant>SNDRV_DEV_LOWLELVEL</constant> , its destructor is 
-      called at the last.  That is, it is assured that all other
-      components like PCMs and controls have already been released.
-      You don't have to stop PCMs, etc. explicitly, but just
-      call low-level hardware stopping.
-      </para>

-      <para>
-        The management of a memory-mapped region is almost as same as

-        The PCM middle layer of ALSA is quite powerful and it is only
-      necessary for each driver to implement the low-level functions
-      to access its hardware.
-      </para>
-
-      <para>
-        For accessing to the PCM layer, you need to include
-      <filename>&lt;sound/pcm.h&gt;</filename> first. In addition,
-      <filename>&lt;sound/pcm_params.h&gt;</filename> might be needed
-      if you access to some functions related with hw_param. 
-      </para>
-
-      <para>
-        Each card device can have up to four pcm instances. A pcm
-      instance corresponds to a pcm device file. The limitation of
-      number of instances comes only from the available bit size of
-      the Linux's device numbers. Once when 64bit device number is
-      used, we'll have more pcm instances available. 
-      </para>
-
-      <para>
-        A pcm instance consists of pcm playback and capture streams,
-      and each pcm stream consists of one or more pcm substreams. Some
-      soundcards support multiple playback functions. For example,
-      emu10k1 has a PCM playback of 32 stereo substreams. In this case, at
-      each open, a free substream is (usually) automatically chosen
-      and opened. Meanwhile, when only one substream exists and it was
-      already opened, the successful open will either block
-      or error with <constant>EAGAIN</constant> according to the
-      file open mode. But you don't have to care about such details in your
-      driver. The PCM middle layer will take care of such work.

-	The PCM configurations are stored in the runtime instance

-	One thing to be noted is that the configured buffer and period
-	sizes are stored in <quote>frames</quote> in the runtime.
-        In the ALSA world, 1 frame = channels * samples-size.
-	For conversion between frames and bytes, you can use the

-      not.  For example, the <parameter>hw_params</parameter> callback is
-      non-atomic, while <parameter>trigger</parameter> callback is
-      atomic.  This means, the latter is called already in a spinlock
-      held by the PCM middle layer. Please take this atomicity into
-      account when you choose a locking scheme in the callbacks.
-      </para>
-
-      <para>
-      In the atomic callbacks, you cannot use functions which may call
-      <function>schedule</function> or go to
-      <function>sleep</function>.  Semaphores and mutexes can sleep,
-      and hence they cannot be used inside the atomic callbacks
-      (e.g. <parameter>trigger</parameter> callback).
-      To implement some delay in such a callback, please use
-      <function>udelay()</function> or <function>mdelay()</function>.

-      All three atomic callbacks (trigger, pointer, and ack) are
-      called with local interrupts disabled.
-      </para>
-
-      <para>
-      The recent changes in PCM core code, however, allow all PCM
-      operations to be non-atomic.  This assumes that the all caller
-      sides are in non-atomic contexts.  For example, the function
-      <function>snd_pcm_period_elapsed()</function> is called
-      typically from the interrupt handler.  But, if you set up the
-      driver to use a threaded interrupt handler, this call can be in
-      non-atomic context, too.  In such a case, you can set
-      <structfield>nonatomic</structfield> filed of
-      <structname>snd_pcm</structname> object after creating it.
-      When this flag is set, mutex and rwsem are used internally in
-      the PCM core instead of spin and rwlocks, so that you can call
-      all PCM functions safely in a non-atomic context.

-        Many soundcards have built-in MIDI (MPU401-UART)
-      interfaces. When the soundcard supports the standard MPU401-UART
-      interface, most likely you can use the ALSA MPU401-UART API. The
-      MPU401-UART API is defined in
-      <filename>&lt;sound/mpu401.h&gt;</filename>. 
-      </para>
-
-      <para>
-        Some soundchips have a similar but slightly different
-      implementation of mpu401 stuff. For example, emu10k1 has its own
-      mpu401 routines.

-
-      <para>
-        The 4th argument is the I/O port address. Many
-      backward-compatible MPU401 have an I/O port such as 0x330. Or, it
-      might be a part of its own PCI I/O region. It depends on the
-      chip design. 
-      </para>
-
-      <para>
-	The 5th argument is a bitflag for additional information.
-        When the I/O port address above is part of the PCI I/O
-      region, the MPU401 I/O port might have been already allocated
-      (reserved) by the driver itself. In such a case, pass a bit flag
-      <constant>MPU401_INFO_INTEGRATED</constant>,
-      and the mpu401-uart layer will allocate the I/O ports by itself.

-	When the controller supports only the input or output MIDI stream,

-	<constant>MPU401_INFO_MMIO</constant> bitflag is used to change

-	When <constant>MPU401_INFO_TX_IRQ</constant> is set, the output

-	by itself to start processing the output stream in the irq handler.

-      <para>
-        ALSA provides several different buffer allocation functions
-      depending on the bus and the architecture. All these have a
-      consistent API. The allocation of physically-contiguous pages is
-      done via

-      is the bus type. 
-      </para>
-
-      <para>
-        The allocation of pages with fallback is
-      <function>snd_malloc_xxx_pages_fallback()</function>. This
-      function tries to allocate the specified pages but if the pages
-      are not available, it tries to reduce the page sizes until

-
-      <para>
-      Usually, ALSA drivers try to allocate and reserve
-       a large contiguous physical space
-       at the time the module is loaded for the later use.
-       This is called <quote>pre-allocation</quote>.
-       As already written, you can call the following function at

-      </para>
-
-      <para>
-      The second argument (type) and the third argument (device pointer)

-    <section id="buffer-and-memory-external-hardware">
-      <title>External Hardware Buffers</title>
-      <para>
-        Some chips have their own hardware buffers and the DMA
-      transfer from the host memory is not available. In such a case,
-      you need to either 1) copy/set the audio data directly to the
-      external hardware buffer, or 2) make an intermediate buffer and
-      copy/set the data from it to the external hardware buffer in
-      interrupts (or in tasklets, preferably).
-      </para>
-
-      <para>
-        The first case works fine if the external hardware buffer is large
-      enough.  This method doesn't need any extra buffers and thus is
-      more effective. You need to define the
-      <structfield>copy</structfield> and
-      <structfield>silence</structfield> callbacks for 
-      the data transfer. However, there is a drawback: it cannot
-      be mmapped. The examples are GUS's GF1 PCM or emu8000's
-      wavetable PCM. 
-      </para>
-
-      <para>
-        The second case allows for mmap on the buffer, although you have
-      to handle an interrupt or a tasklet to transfer the data
-      from the intermediate buffer to the hardware buffer. You can find an
-      example in the vxpocket driver. 
-      </para>
-
-      <para>
-        Another case is when the chip uses a PCI memory-map
-      region for the buffer instead of the host memory. In this case,
-      mmap is available only on certain architectures like the Intel one.
-      In non-mmap mode, the data cannot be transferred as in the normal
-      way. Thus you need to define the <structfield>copy</structfield> and
-      <structfield>silence</structfield> callbacks as well, 
-      as in the cases above. The examples are found in
-      <filename>rme32.c</filename> and <filename>rme96.c</filename>. 
-      </para>
-
-      <para>
-        The implementation of the <structfield>copy</structfield> and
-        <structfield>silence</structfield> callbacks depends upon 
-        whether the hardware supports interleaved or non-interleaved
-        samples. The <structfield>copy</structfield> callback is
-        defined like below, a bit 
-        differently depending whether the direction is playback or
-        capture: 
-
-        <informalexample>

-  static int capture_copy(struct snd_pcm_substream *substream, int channel,
-               snd_pcm_uframes_t pos, void *dst, snd_pcm_uframes_t count);
-]]>
-          </programlisting>
-        </informalexample>
-      </para>
-
-      <para>
-        In the case of interleaved samples, the second argument
-      (<parameter>channel</parameter>) is not used. The third argument
-      (<parameter>pos</parameter>) points the 
-      current position offset in frames. 
-      </para>
-
-      <para>
-        The meaning of the fourth argument is different between
-      playback and capture. For playback, it holds the source data
-      pointer, and for capture, it's the destination data pointer. 
-      </para>
-
-      <para>
-        The last argument is the number of frames to be copied.
-      </para>
-
-      <para>
-        What you have to do in this callback is again different
-        between playback and capture directions. In the
-        playback case, you copy the given amount of data
-        (<parameter>count</parameter>) at the specified pointer
-        (<parameter>src</parameter>) to the specified offset
-        (<parameter>pos</parameter>) on the hardware buffer. When

-          <programlisting>
-<![CDATA[

-        data (<parameter>count</parameter>) at the specified offset
-        (<parameter>pos</parameter>) on the hardware buffer to the
-        specified pointer (<parameter>dst</parameter>).

-        </informalexample>
-
-        Note that both the position and the amount of data are given
-      in frames. 
-      </para>
-
-      <para>
-        In the case of non-interleaved samples, the implementation
-      will be a bit more complicated. 
-      </para>
-
-      <para>
-        You need to check the channel argument, and if it's -1, copy

-    <para>
-      ALSA provides an easy interface for procfs. The proc files are
-      very useful for debugging. I recommend you set up proc files if

-      dumps. The API is found in
-      <filename>&lt;sound/info.h&gt;</filename>. 
-    </para>
-
-    <para>
-      To create a proc file, call
-      <function>snd_card_proc_new()</function>.

-]]>
-        </programlisting>
-      </informalexample>
-
-      where the second argument specifies the name of the proc file to be
-    created. The above example will create a file
-    <filename>my-file</filename> under the card directory,
-    e.g. <filename>/proc/asound/card0/my-file</filename>. 
-    </para>
-
-    <para>
-    Like other components, the proc entry created via

-    functions.
-    </para>
-
-    <para>
-      When the creation is successful, the function stores a new
-    instance in the pointer given in the third argument.
-    It is initialized as a text proc file for read only.  To use
-    this proc file as a read-only text file as it is, set the read
-    callback with a private data via 
-     <function>snd_info_set_text_ops()</function>.

-      The read/write callbacks of raw mode are more direct than the text mode.

-    <title>Power Management</title>
-    <para>
-      If the chip is supposed to work with suspend/resume
-      functions, you need to add power-management code to the
-      driver. The additional code for power-management should be
-      <function>ifdef</function>'ed with
-      <constant>CONFIG_PM</constant>. 
-    </para>
-
-	<para>
-	If the driver <emphasis>fully</emphasis> supports suspend/resume
-	that is, the device can be
-	properly resumed to its state when suspend was called,
-	you can set the <constant>SNDRV_PCM_INFO_RESUME</constant> flag
-	in the pcm info field.  Usually, this is possible when the
-	registers of the chip can be safely saved and restored to
-	RAM. If this is set, the trigger callback is called with
-	<constant>SNDRV_PCM_TRIGGER_RESUME</constant> after the resume
-	callback completes. 
-	</para>
-
-	<para>
-	Even if the driver doesn't support PM fully but 
-	partial suspend/resume is still possible, it's still worthy to
-	implement suspend/resume callbacks. In such a case, applications
-	would reset the status by calling
-	<function>snd_pcm_prepare()</function> and restart the stream
-	appropriately.  Hence, you can define suspend/resume callbacks
-	below but don't set <constant>SNDRV_PCM_INFO_RESUME</constant>
-	info flag to the PCM.
-	</para>
-	
-	<para>
-	Note that the trigger with SUSPEND can always be called when
-	<function>snd_pcm_suspend_all</function> is called,
-	regardless of the <constant>SNDRV_PCM_INFO_RESUME</constant> flag.
-	The <constant>RESUME</constant> flag affects only the behavior
-	of <function>snd_pcm_resume()</function>.
-	(Thus, in theory,
-	<constant>SNDRV_PCM_TRIGGER_RESUME</constant> isn't needed
-	to be handled in the trigger callback when no
-	<constant>SNDRV_PCM_INFO_RESUME</constant> flag is set.  But,
-	it's better to keep it for compatibility reasons.)

-    <para>
-      In the earlier version of ALSA drivers, a common

-How to Get Your Change Into the Linux Kernel or Care And Operation Of Your Linus Torvalds
-=========================================================================================
-
-For a person or company who wishes to submit a change to the Linux
-kernel, the process can sometimes be daunting if you're not familiar
-with "the system."  This text is a collection of suggestions which
-can greatly increase the chances of your change being accepted.
-
-This document contains a large number of suggestions in a relatively terse
-format.  For detailed information on how the kernel development process
-works, see :ref:`Documentation/development-process <development_process_main>`.
-Also, read :ref:`Documentation/SubmitChecklist <submitchecklist>`
-for a list of items to check before
-submitting code.  If you are submitting a driver, also read
-:ref:`Documentation/SubmittingDrivers <submittingdrivers>`;
-for device tree binding patches, read
-Documentation/devicetree/bindings/submitting-patches.txt.
-
-Many of these steps describe the default behavior of the ``git`` version
-control system; if you use ``git`` to prepare your patches, you'll find much
-of the mechanical work done for you, though you'll still need to prepare
-and document a sensible set of patches.  In general, use of ``git`` will make
-your life as a kernel developer easier.
-
-Creating and Sending your Change
-********************************
-
-
-0) Obtain a current source tree
--------------------------------
-
-If you do not have a repository with the current kernel source handy, use
-``git`` to obtain one.  You'll want to start with the mainline repository,
-which can be grabbed with::
-
-  git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
-
-Note, however, that you may not want to develop against the mainline tree
-directly.  Most subsystem maintainers run their own trees and want to see
-patches prepared against those trees.  See the **T:** entry for the subsystem
-in the MAINTAINERS file to find that tree, or simply ask the maintainer if
-the tree is not listed there.
-
-It is still possible to download kernel releases via tarballs (as described
-in the next section), but that is the hard way to do kernel development.
-
-1) ``diff -up``
----------------
-
-If you must generate your patches by hand, use ``diff -up`` or ``diff -uprN``
-to create patches.  Git generates patches in this form by default; if
-you're using ``git``, you can skip this section entirely.
-
-All changes to the Linux kernel occur in the form of patches, as
-generated by :manpage:`diff(1)`.  When creating your patch, make sure to
-create it in "unified diff" format, as supplied by the ``-u`` argument
-to :manpage:`diff(1)`.
-Also, please use the ``-p`` argument which shows which C function each
-change is in - that makes the resultant ``diff`` a lot easier to read.
-Patches should be based in the root kernel source directory,
-not in any lower subdirectory.
-
-To create a patch for a single file, it is often sufficient to do::
-
-	SRCTREE= linux
-	MYFILE=  drivers/net/mydriver.c
-
-	cd $SRCTREE
-	cp $MYFILE $MYFILE.orig
-	vi $MYFILE	# make your change
-	cd ..
-	diff -up $SRCTREE/$MYFILE{.orig,} > /tmp/patch
-
-To create a patch for multiple files, you should unpack a "vanilla",
-or unmodified kernel source tree, and generate a ``diff`` against your
-own source tree.  For example::
-
-	MYSRC= /devel/linux
-
-	tar xvfz linux-3.19.tar.gz
-	mv linux-3.19 linux-3.19-vanilla
-	diff -uprN -X linux-3.19-vanilla/Documentation/dontdiff \
-		linux-3.19-vanilla $MYSRC > /tmp/patch
-
-``dontdiff`` is a list of files which are generated by the kernel during
-the build process, and should be ignored in any :manpage:`diff(1)`-generated
-patch.
-
-Make sure your patch does not include any extra files which do not
-belong in a patch submission.  Make sure to review your patch -after-
-generating it with :manpage:`diff(1)`, to ensure accuracy.
-
-If your changes produce a lot of deltas, you need to split them into
-individual patches which modify things in logical stages; see
-:ref:`split_changes`.  This will facilitate review by other kernel developers,
-very important if you want your patch accepted.
-
-If you're using ``git``, ``git rebase -i`` can help you with this process.  If
-you're not using ``git``, ``quilt`` <http://savannah.nongnu.org/projects/quilt>
-is another popular alternative.
-
-.. _describe_changes:
-
-2) Describe your changes
-------------------------
-
-Describe your problem.  Whether your patch is a one-line bug fix or
-5000 lines of a new feature, there must be an underlying problem that
-motivated you to do this work.  Convince the reviewer that there is a
-problem worth fixing and that it makes sense for them to read past the
-first paragraph.
-
-Describe user-visible impact.  Straight up crashes and lockups are
-pretty convincing, but not all bugs are that blatant.  Even if the
-problem was spotted during code review, describe the impact you think
-it can have on users.  Keep in mind that the majority of Linux
-installations run kernels from secondary stable trees or
-vendor/product-specific trees that cherry-pick only specific patches
-from upstream, so include anything that could help route your change
-downstream: provoking circumstances, excerpts from dmesg, crash
-descriptions, performance regressions, latency spikes, lockups, etc.
-
-Quantify optimizations and trade-offs.  If you claim improvements in
-performance, memory consumption, stack footprint, or binary size,
-include numbers that back them up.  But also describe non-obvious
-costs.  Optimizations usually aren't free but trade-offs between CPU,
-memory, and readability; or, when it comes to heuristics, between
-different workloads.  Describe the expected downsides of your
-optimization so that the reviewer can weigh costs against benefits.
-
-Once the problem is established, describe what you are actually doing
-about it in technical detail.  It's important to describe the change
-in plain English for the reviewer to verify that the code is behaving
-as you intend it to.
-
-The maintainer will thank you if you write your patch description in a
-form which can be easily pulled into Linux's source code management
-system, ``git``, as a "commit log".  See :ref:`explicit_in_reply_to`.
-
-Solve only one problem per patch.  If your description starts to get
-long, that's a sign that you probably need to split up your patch.
-See :ref:`split_changes`.
-
-When you submit or resubmit a patch or patch series, include the
-complete patch description and justification for it.  Don't just
-say that this is version N of the patch (series).  Don't expect the
-subsystem maintainer to refer back to earlier patch versions or referenced
-URLs to find the patch description and put that into the patch.
-I.e., the patch (series) and its description should be self-contained.
-This benefits both the maintainers and reviewers.  Some reviewers
-probably didn't even receive earlier versions of the patch.
-
-Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
-instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
-to do frotz", as if you are giving orders to the codebase to change
-its behaviour.
-
-If the patch fixes a logged bug entry, refer to that bug entry by
-number and URL.  If the patch follows from a mailing list discussion,
-give a URL to the mailing list archive; use the https://lkml.kernel.org/
-redirector with a ``Message-Id``, to ensure that the links cannot become
-stale.
-
-However, try to make your explanation understandable without external
-resources.  In addition to giving a URL to a mailing list archive or
-bug, summarize the relevant points of the discussion that led to the
-patch as submitted.
-
-If you want to refer to a specific commit, don't just refer to the
-SHA-1 ID of the commit. Please also include the oneline summary of
-the commit, to make it easier for reviewers to know what it is about.
-Example::
-
-	Commit e21d2170f36602ae2708 ("video: remove unnecessary
-	platform_set_drvdata()") removed the unnecessary
-	platform_set_drvdata(), but left the variable "dev" unused,
-	delete it.
-
-You should also be sure to use at least the first twelve characters of the
-SHA-1 ID.  The kernel repository holds a *lot* of objects, making
-collisions with shorter IDs a real possibility.  Bear in mind that, even if
-there is no collision with your six-character ID now, that condition may
-change five years from now.
-
-If your patch fixes a bug in a specific commit, e.g. you found an issue using
-``git bisect``, please use the 'Fixes:' tag with the first 12 characters of
-the SHA-1 ID, and the one line summary.  For example::
-
-	Fixes: e21d2170f366 ("video: remove unnecessary platform_set_drvdata()")
-
-The following ``git config`` settings can be used to add a pretty format for
-outputting the above style in the ``git log`` or ``git show`` commands::
-
-	[core]
-		abbrev = 12
-	[pretty]
-		fixes = Fixes: %h (\"%s\")
-
-.. _split_changes:
-
-3) Separate your changes
-------------------------
-
-Separate each **logical change** into a separate patch.
-
-For example, if your changes include both bug fixes and performance
-enhancements for a single driver, separate those changes into two
-or more patches.  If your changes include an API update, and a new
-driver which uses that new API, separate those into two patches.
-
-On the other hand, if you make a single change to numerous files,
-group those changes into a single patch.  Thus a single logical change
-is contained within a single patch.
-
-The point to remember is that each patch should make an easily understood
-change that can be verified by reviewers.  Each patch should be justifiable
-on its own merits.
-
-If one patch depends on another patch in order for a change to be
-complete, that is OK.  Simply note **"this patch depends on patch X"**
-in your patch description.
-
-When dividing your change into a series of patches, take special care to
-ensure that the kernel builds and runs properly after each patch in the
-series.  Developers using ``git bisect`` to track down a problem can end up
-splitting your patch series at any point; they will not thank you if you
-introduce bugs in the middle.
-
-If you cannot condense your patch set into a smaller set of patches,
-then only post say 15 or so at a time and wait for review and integration.
-
-
-
-4) Style-check your changes
----------------------------
-
-Check your patch for basic style violations, details of which can be
-found in
-:ref:`Documentation/CodingStyle <codingstyle>`.
-Failure to do so simply wastes
-the reviewers time and will get your patch rejected, probably
-without even being read.
-
-One significant exception is when moving code from one file to
-another -- in this case you should not modify the moved code at all in
-the same patch which moves it.  This clearly delineates the act of
-moving the code and your changes.  This greatly aids review of the
-actual differences and allows tools to better track the history of
-the code itself.
-
-Check your patches with the patch style checker prior to submission
-(scripts/checkpatch.pl).  Note, though, that the style checker should be
-viewed as a guide, not as a replacement for human judgment.  If your code
-looks better with a violation then its probably best left alone.
-
-The checker reports at three levels:
- - ERROR: things that are very likely to be wrong
- - WARNING: things requiring careful review
- - CHECK: things requiring thought
-
-You should be able to justify all violations that remain in your
-patch.
-
-
-5) Select the recipients for your patch
----------------------------------------
-
-You should always copy the appropriate subsystem maintainer(s) on any patch
-to code that they maintain; look through the MAINTAINERS file and the
-source code revision history to see who those maintainers are.  The
-script scripts/get_maintainer.pl can be very useful at this step.  If you
-cannot find a maintainer for the subsystem you are working on, Andrew
-Morton (akpm@linux-foundation.org) serves as a maintainer of last resort.
-
-You should also normally choose at least one mailing list to receive a copy
-of your patch set.  linux-kernel@vger.kernel.org functions as a list of
-last resort, but the volume on that list has caused a number of developers
-to tune it out.  Look in the MAINTAINERS file for a subsystem-specific
-list; your patch will probably get more attention there.  Please do not
-spam unrelated lists, though.
-
-Many kernel-related lists are hosted on vger.kernel.org; you can find a
-list of them at http://vger.kernel.org/vger-lists.html.  There are
-kernel-related lists hosted elsewhere as well, though.
-
-Do not send more than 15 patches at once to the vger mailing lists!!!
-
-Linus Torvalds is the final arbiter of all changes accepted into the
-Linux kernel.  His e-mail address is <torvalds@linux-foundation.org>.
-He gets a lot of e-mail, and, at this point, very few patches go through
-Linus directly, so typically you should do your best to -avoid-
-sending him e-mail.
-
-If you have a patch that fixes an exploitable security bug, send that patch
-to security@kernel.org.  For severe bugs, a short embargo may be considered
-to allow distributors to get the patch out to users; in such cases,
-obviously, the patch should not be sent to any public lists.
-
-Patches that fix a severe bug in a released kernel should be directed
-toward the stable maintainers by putting a line like this::
-
-  Cc: stable@vger.kernel.org
-
-into the sign-off area of your patch (note, NOT an email recipient).  You
-should also read
-:ref:`Documentation/stable_kernel_rules.txt <stable_kernel_rules>`
-in addition to this file.
-
-Note, however, that some subsystem maintainers want to come to their own
-conclusions on which patches should go to the stable trees.  The networking
-maintainer, in particular, would rather not see individual developers
-adding lines like the above to their patches.
-
-If changes affect userland-kernel interfaces, please send the MAN-PAGES
-maintainer (as listed in the MAINTAINERS file) a man-pages patch, or at
-least a notification of the change, so that some information makes its way
-into the manual pages.  User-space API changes should also be copied to
-linux-api@vger.kernel.org.
-
-For small patches you may want to CC the Trivial Patch Monkey
-trivial@kernel.org which collects "trivial" patches. Have a look
-into the MAINTAINERS file for its current manager.
-
-Trivial patches must qualify for one of the following rules:
-
-- Spelling fixes in documentation
-- Spelling fixes for errors which could break :manpage:`grep(1)`
-- Warning fixes (cluttering with useless warnings is bad)
-- Compilation fixes (only if they are actually correct)
-- Runtime fixes (only if they actually fix things)
-- Removing use of deprecated functions/macros
-- Contact detail and documentation fixes
-- Non-portable code replaced by portable code (even in arch-specific,
-  since people copy, as long as it's trivial)
-- Any fix by the author/maintainer of the file (ie. patch monkey
-  in re-transmission mode)
-
-
-
-6) No MIME, no links, no compression, no attachments.  Just plain text
-----------------------------------------------------------------------
-
-Linus and other kernel developers need to be able to read and comment
-on the changes you are submitting.  It is important for a kernel
-developer to be able to "quote" your changes, using standard e-mail
-tools, so that they may comment on specific portions of your code.
-
-For this reason, all patches should be submitted by e-mail "inline".
-
-.. warning::
-
-  Be wary of your editor's word-wrap corrupting your patch,
-  if you choose to cut-n-paste your patch.
-
-Do not attach the patch as a MIME attachment, compressed or not.
-Many popular e-mail applications will not always transmit a MIME
-attachment as plain text, making it impossible to comment on your
-code.  A MIME attachment also takes Linus a bit more time to process,
-decreasing the likelihood of your MIME-attached change being accepted.
-
-Exception:  If your mailer is mangling patches then someone may ask
-you to re-send them using MIME.
-
-See :ref:`Documentation/email-clients.txt <email_clients>`
-for hints about configuring your e-mail client so that it sends your patches
-untouched.
-
-7) E-mail size
---------------
-
-Large changes are not appropriate for mailing lists, and some
-maintainers.  If your patch, uncompressed, exceeds 300 kB in size,
-it is preferred that you store your patch on an Internet-accessible
-server, and provide instead a URL (link) pointing to your patch.  But note
-that if your patch exceeds 300 kB, it almost certainly needs to be broken up
-anyway.
-
-8) Respond to review comments
------------------------------
-
-Your patch will almost certainly get comments from reviewers on ways in
-which the patch can be improved.  You must respond to those comments;
-ignoring reviewers is a good way to get ignored in return.  Review comments
-or questions that do not lead to a code change should almost certainly
-bring about a comment or changelog entry so that the next reviewer better
-understands what is going on.
-
-Be sure to tell the reviewers what changes you are making and to thank them
-for their time.  Code review is a tiring and time-consuming process, and
-reviewers sometimes get grumpy.  Even in that case, though, respond
-politely and address the problems they have pointed out.
-
-
-9) Don't get discouraged - or impatient
----------------------------------------
-
-After you have submitted your change, be patient and wait.  Reviewers are
-busy people and may not get to your patch right away.
-
-Once upon a time, patches used to disappear into the void without comment,
-but the development process works more smoothly than that now.  You should
-receive comments within a week or so; if that does not happen, make sure
-that you have sent your patches to the right place.  Wait for a minimum of
-one week before resubmitting or pinging reviewers - possibly longer during
-busy times like merge windows.
-
-
-10) Include PATCH in the subject
---------------------------------
-
-Due to high e-mail traffic to Linus, and to linux-kernel, it is common
-convention to prefix your subject line with [PATCH].  This lets Linus
-and other kernel developers more easily distinguish patches from other
-e-mail discussions.
-
-
-
-11) Sign your work
-------------------
-
-To improve tracking of who did what, especially with patches that can
-percolate to their final resting place in the kernel through several
-layers of maintainers, we've introduced a "sign-off" procedure on
-patches that are being emailed around.
-
-The sign-off is a simple line at the end of the explanation for the
-patch, which certifies that you wrote it or otherwise have the right to
-pass it on as an open-source patch.  The rules are pretty simple: if you
-can certify the below:
-
-Developer's Certificate of Origin 1.1
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-By making a contribution to this project, I certify that:
-
-        (a) The contribution was created in whole or in part by me and I
-            have the right to submit it under the open source license
-            indicated in the file; or
-
-        (b) The contribution is based upon previous work that, to the best
-            of my knowledge, is covered under an appropriate open source
-            license and I have the right under that license to submit that
-            work with modifications, whether created in whole or in part
-            by me, under the same open source license (unless I am
-            permitted to submit under a different license), as indicated
-            in the file; or
-
-        (c) The contribution was provided directly to me by some other
-            person who certified (a), (b) or (c) and I have not modified
-            it.
-
-        (d) I understand and agree that this project and the contribution
-            are public and that a record of the contribution (including all
-            personal information I submit with it, including my sign-off) is
-            maintained indefinitely and may be redistributed consistent with
-            this project or the open source license(s) involved.
-
-then you just add a line saying::
-
-	Signed-off-by: Random J Developer <random@developer.example.org>
-
-using your real name (sorry, no pseudonyms or anonymous contributions.)
-
-Some people also put extra tags at the end.  They'll just be ignored for
-now, but you can do this to mark internal company procedures or just
-point out some special detail about the sign-off.
-
-If you are a subsystem or branch maintainer, sometimes you need to slightly
-modify patches you receive in order to merge them, because the code is not
-exactly the same in your tree and the submitters'. If you stick strictly to
-rule (c), you should ask the submitter to rediff, but this is a totally
-counter-productive waste of time and energy. Rule (b) allows you to adjust
-the code, but then it is very impolite to change one submitter's code and
-make him endorse your bugs. To solve this problem, it is recommended that
-you add a line between the last Signed-off-by header and yours, indicating
-the nature of your changes. While there is nothing mandatory about this, it
-seems like prepending the description with your mail and/or name, all
-enclosed in square brackets, is noticeable enough to make it obvious that
-you are responsible for last-minute changes. Example::
-
-	Signed-off-by: Random J Developer <random@developer.example.org>
-	[lucky@maintainer.example.org: struct foo moved from foo.c to foo.h]
-	Signed-off-by: Lucky K Maintainer <lucky@maintainer.example.org>
-
-This practice is particularly helpful if you maintain a stable branch and
-want at the same time to credit the author, track changes, merge the fix,
-and protect the submitter from complaints. Note that under no circumstances
-can you change the author's identity (the From header), as it is the one
-which appears in the changelog.
-
-Special note to back-porters: It seems to be a common and useful practice
-to insert an indication of the origin of a patch at the top of the commit
-message (just after the subject line) to facilitate tracking. For instance,
-here's what we see in a 3.x-stable release::
-

-tracking your trees, and to people trying to troubleshoot bugs in your

-
-
-12) When to use Acked-by: and Cc:
----------------------------------
-
-The Signed-off-by: tag indicates that the signer was involved in the
-development of the patch, or that he/she was in the patch's delivery path.
-
-If a person was not directly involved in the preparation or handling of a
-patch but wishes to signify and record their approval of it then they can
-ask to have an Acked-by: line added to the patch's changelog.
-
-Acked-by: is often used by the maintainer of the affected code when that
-maintainer neither contributed to nor forwarded the patch.
-
-Acked-by: is not as formal as Signed-off-by:.  It is a record that the acker
-has at least reviewed the patch and has indicated acceptance.  Hence patch
-mergers will sometimes manually convert an acker's "yep, looks good to me"
-into an Acked-by: (but note that it is usually better to ask for an
-explicit ack).
-
-Acked-by: does not necessarily indicate acknowledgement of the entire patch.
-For example, if a patch affects multiple subsystems and has an Acked-by: from
-one subsystem maintainer then this usually indicates acknowledgement of just
-the part which affects that maintainer's code.  Judgement should be used here.
-When in doubt people should refer to the original discussion in the mailing
-list archives.
-
-If a person has had the opportunity to comment on a patch, but has not
-provided such comments, you may optionally add a ``Cc:`` tag to the patch.
-This is the only tag which might be added without an explicit action by the
-person it names - but it should indicate that this person was copied on the
-patch.  This tag documents that potentially interested parties
-have been included in the discussion.
-
-
-13) Using Reported-by:, Tested-by:, Reviewed-by:, Suggested-by: and Fixes:
---------------------------------------------------------------------------
-
-The Reported-by tag gives credit to people who find bugs and report them and it
-hopefully inspires them to help us again in the future.  Please note that if
-the bug was reported in private, then ask for permission first before using the
-Reported-by tag.
-
-A Tested-by: tag indicates that the patch has been successfully tested (in
-some environment) by the person named.  This tag informs maintainers that
-some testing has been performed, provides a means to locate testers for
-future patches, and ensures credit for the testers.
-
-Reviewed-by:, instead, indicates that the patch has been reviewed and found
-acceptable according to the Reviewer's Statement:
-
-Reviewer's statement of oversight
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-By offering my Reviewed-by: tag, I state that:
-
-	 (a) I have carried out a technical review of this patch to
-	     evaluate its appropriateness and readiness for inclusion into
-	     the mainline kernel.
-
-	 (b) Any problems, concerns, or questions relating to the patch
-	     have been communicated back to the submitter.  I am satisfied
-	     with the submitter's response to my comments.
-
-	 (c) While there may be things that could be improved with this
-	     submission, I believe that it is, at this time, (1) a
-	     worthwhile modification to the kernel, and (2) free of known
-	     issues which would argue against its inclusion.
-
-	 (d) While I have reviewed the patch and believe it to be sound, I
-	     do not (unless explicitly stated elsewhere) make any
-	     warranties or guarantees that it will achieve its stated
-	     purpose or function properly in any given situation.
-
-A Reviewed-by tag is a statement of opinion that the patch is an
-appropriate modification of the kernel without any remaining serious
-technical issues.  Any interested reviewer (who has done the work) can
-offer a Reviewed-by tag for a patch.  This tag serves to give credit to
-reviewers and to inform maintainers of the degree of review which has been
-done on the patch.  Reviewed-by: tags, when supplied by reviewers known to
-understand the subject area and to perform thorough reviews, will normally
-increase the likelihood of your patch getting into the kernel.
-
-A Suggested-by: tag indicates that the patch idea is suggested by the person
-named and ensures credit to the person for the idea. Please note that this
-tag should not be added without the reporter's permission, especially if the
-idea was not posted in a public forum. That said, if we diligently credit our
-idea reporters, they will, hopefully, be inspired to help us again in the
-future.
-
-A Fixes: tag indicates that the patch fixes an issue in a previous commit. It
-is used to make it easy to determine where a bug originated, which can help
-review a bug fix. This tag also assists the stable kernel team in determining
-which stable kernel versions should receive your fix. This is the preferred
-method for indicating a bug fixed by the patch. See :ref:`describe_changes`
-for more details.
-
-
-14) The canonical patch format
-------------------------------
-
-This section describes how the patch itself should be formatted.  Note
-that, if you have your patches stored in a ``git`` repository, proper patch
-formatting can be had with ``git format-patch``.  The tools cannot create
-the necessary text, though, so read the instructions below anyway.
-
-The canonical patch subject line is::
-
-    Subject: [PATCH 001/123] subsystem: summary phrase
-
-The canonical patch message body contains the following:
-
-  - A ``from`` line specifying the patch author (only needed if the person
-    sending the patch is not the author).
-
-  - An empty line.
-
-  - The body of the explanation, line wrapped at 75 columns, which will
-    be copied to the permanent changelog to describe this patch.
-
-  - The ``Signed-off-by:`` lines, described above, which will
-    also go in the changelog.
-
-  - A marker line containing simply ``---``.
-
-  - Any additional comments not suitable for the changelog.
-
-  - The actual patch (``diff`` output).
-
-The Subject line format makes it very easy to sort the emails
-alphabetically by subject line - pretty much any email reader will
-support that - since because the sequence number is zero-padded,
-the numerical and alphabetic sort is the same.
-
-The ``subsystem`` in the email's Subject should identify which
-area or subsystem of the kernel is being patched.
-
-The ``summary phrase`` in the email's Subject should concisely
-describe the patch which that email contains.  The ``summary
-phrase`` should not be a filename.  Do not use the same ``summary
-phrase`` for every patch in a whole patch series (where a ``patch
-series`` is an ordered sequence of multiple, related patches).
-
-Bear in mind that the ``summary phrase`` of your email becomes a
-globally-unique identifier for that patch.  It propagates all the way
-into the ``git`` changelog.  The ``summary phrase`` may later be used in
-developer discussions which refer to the patch.  People will want to
-google for the ``summary phrase`` to read discussion regarding that
-patch.  It will also be the only thing that people may quickly see
-when, two or three months later, they are going through perhaps
-thousands of patches using tools such as ``gitk`` or ``git log
---oneline``.
-
-For these reasons, the ``summary`` must be no more than 70-75
-characters, and it must describe both what the patch changes, as well
-as why the patch might be necessary.  It is challenging to be both
-succinct and descriptive, but that is what a well-written summary
-should do.
-
-The ``summary phrase`` may be prefixed by tags enclosed in square
-brackets: "Subject: [PATCH <tag>...] <summary phrase>".  The tags are
-not considered part of the summary phrase, but describe how the patch
-should be treated.  Common tags might include a version descriptor if
-the multiple versions of the patch have been sent out in response to
-comments (i.e., "v1, v2, v3"), or "RFC" to indicate a request for
-comments.  If there are four patches in a patch series the individual
-patches may be numbered like this: 1/4, 2/4, 3/4, 4/4.  This assures
-that developers understand the order in which the patches should be
-applied and that they have reviewed or applied all of the patches in
-the patch series.
-
-A couple of example Subjects::
-
-    Subject: [PATCH 2/5] ext2: improve scalability of bitmap searching
-    Subject: [PATCH v2 01/27] x86: fix eflags tracking
-
-The ``from`` line must be the very first line in the message body,
-and has the form:
-
-        From: Original Author <author@example.com>
-
-The ``from`` line specifies who will be credited as the author of the
-patch in the permanent changelog.  If the ``from`` line is missing,
-then the ``From:`` line from the email header will be used to determine
-the patch author in the changelog.
-
-The explanation body will be committed to the permanent source
-changelog, so should make sense to a competent reader who has long
-since forgotten the immediate details of the discussion that might
-have led to this patch.  Including symptoms of the failure which the
-patch addresses (kernel log messages, oops messages, etc.) is
-especially useful for people who might be searching the commit logs
-looking for the applicable patch.  If a patch fixes a compile failure,
-it may not be necessary to include _all_ of the compile failures; just
-enough that it is likely that someone searching for the patch can find
-it.  As in the ``summary phrase``, it is important to be both succinct as
-well as descriptive.
-
-The ``---`` marker line serves the essential purpose of marking for patch
-handling tools where the changelog message ends.
-
-One good use for the additional comments after the ``---`` marker is for
-a ``diffstat``, to show what files have changed, and the number of
-inserted and deleted lines per file.  A ``diffstat`` is especially useful
-on bigger patches.  Other comments relevant only to the moment or the
-maintainer, not suitable for the permanent changelog, should also go
-here.  A good example of such comments might be ``patch changelogs``
-which describe what has changed between the v1 and v2 version of the
-patch.
-
-If you are going to include a ``diffstat`` after the ``---`` marker, please
-use ``diffstat`` options ``-p 1 -w 70`` so that filenames are listed from
-the top of the kernel source tree and don't use too much horizontal
-space (easily fit in 80 columns, maybe with some indentation).  (``git``
-generates appropriate diffstats by default.)
-
-See more details on the proper patch format in the following
-references.
-
-.. _explicit_in_reply_to:
-
-15) Explicit In-Reply-To headers
---------------------------------
-
-It can be helpful to manually add In-Reply-To: headers to a patch
-(e.g., when using ``git send-email``) to associate the patch with
-previous relevant discussion, e.g. to link a bug fix to the email with
-the bug report.  However, for a multi-patch series, it is generally
-best to avoid using In-Reply-To: to link to older versions of the
-series.  This way multiple versions of the patch don't become an
-unmanageable forest of references in email clients.  If a link is
-helpful, you can use the https://lkml.kernel.org/ redirector (e.g., in
-the cover email text) to link to an earlier version of the patch series.
-
-
-16) Sending ``git pull`` requests
----------------------------------
-
-If you have a series of patches, it may be most convenient to have the
-maintainer pull them directly into the subsystem repository with a
-``git pull`` operation.  Note, however, that pulling patches from a developer
-requires a higher degree of trust than taking patches from a mailing list.
-As a result, many subsystem maintainers are reluctant to take pull
-requests, especially from new, unknown developers.  If in doubt you can use
-the pull request as the cover letter for a normal posting of the patch
-series, giving the maintainer the option of using either.
-
-A pull request should have [GIT] or [PULL] in the subject line.  The
-request itself should include the repository name and the branch of
-interest on a single line; it should look something like::
-
-  Please pull from
-
-      git://jdelvare.pck.nerim.net/jdelvare-2.6 i2c-for-linus
-
-  to get these changes:
-
-A pull request should also include an overall message saying what will be
-included in the request, a ``git shortlog`` listing of the patches
-themselves, and a ``diffstat`` showing the overall effect of the patch series.
-The easiest way to get all this information together is, of course, to let
-``git`` do it for you with the ``git request-pull`` command.
-
-Some maintainers (including Linus) want to see pull requests from signed
-commits; that increases their confidence that the request actually came
-from you.  Linus, in particular, will not pull from public hosting sites
-like GitHub in the absence of a signed tag.
-
-The first step toward creating such tags is to make a GNUPG key and get it
-signed by one or more core kernel developers.  This step can be hard for
-new developers, but there is no way around it.  Attending conferences can
-be a good way to find developers who can sign your key.
-
-Once you have prepared a patch series in ``git`` that you wish to have somebody
-pull, create a signed tag with ``git tag -s``.  This will create a new tag
-identifying the last commit in the series and containing a signature
-created with your private key.  You will also have the opportunity to add a
-changelog-style message to the tag; this is an ideal place to describe the
-effects of the pull request as a whole.
-
-If the tree the maintainer will be pulling from is not the repository you
-are working from, don't forget to push the signed tag explicitly to the
-public tree.
-
-When generating your pull request, use the signed tag as the target.  A
-command like this will do the trick::
-
-  git request-pull master git://my.public.tree/linux.git my-signed-tag

-Software cursor for VGA    by Pavel Machek <pavel@atrey.karlin.mff.cuni.cz>
-=======================    and Martin Mares <mj@atrey.karlin.mff.cuni.cz>
-
-   Linux now has some ability to manipulate cursor appearance. Normally, you
-can set the size of hardware cursor (and also work around some ugly bugs in
-those miserable Trident cards--see #define TRIDENT_GLITCH in drivers/video/
-vgacon.c). You can now play a few new tricks:  you can make your cursor look
-like a non-blinking red block, make it inverse background of the character it's
-over or to highlight that character and still choose whether the original
-hardware cursor should remain visible or not.  There may be other things I have
-never thought of.
-
-   The cursor appearance is controlled by a "<ESC>[?1;2;3c" escape sequence
-where 1, 2 and 3 are parameters described below. If you omit any of them,
-they will default to zeroes.
-
-   Parameter 1 specifies cursor size (0=default, 1=invisible, 2=underline, ...,
-8=full block) + 16 if you want the software cursor to be applied + 32 if you
-want to always change the background color + 64 if you dislike having the
-background the same as the foreground.  Highlights are ignored for the last two
-flags.
-
-   The second parameter selects character attribute bits you want to change
-(by simply XORing them with the value of this parameter). On standard VGA,
-the high four bits specify background and the low four the foreground. In both
-groups, low three bits set color (as in normal color codes used by the console)
-and the most significant one turns on highlight (or sometimes blinking--it
-depends on the configuration of your VGA).
-
-   The third parameter consists of character attribute bits you want to set.
-Bit setting takes place before bit toggling, so you can simply clear a bit by 
-including it in both the set mask and the toggle mask.
-
-Examples:
-=========
-
-To get normal blinking underline, use: echo -e '\033[?2c'
-To get blinking block, use:            echo -e '\033[?6c'
-To get red non-blinking block, use:    echo -e '\033[?17;0;64c'

+_DSD Device Properties Usage Rules
+----------------------------------
+
+Properties, Property Sets and Property Subsets
+----------------------------------------------
+
+The _DSD (Device Specific Data) configuration object, introduced in ACPI 5.1,
+allows any type of device configuration data to be provided via the ACPI
+namespace.  In principle, the format of the data may be arbitrary, but it has to
+be identified by a UUID which must be recognized by the driver processing the
+_DSD output.  However, there are generic UUIDs defined for _DSD recognized by
+the ACPI subsystem in the Linux kernel which automatically processes the data
+packages associated with them and makes those data available to device drivers
+as "device properties".
+
+A device property is a data item consisting of a string key and a value (of a
+specific type) associated with it.
+
+In the ACPI _DSD context it is an element of the sub-package following the
+generic Device Properties UUID in the _DSD return package as specified in the
+Device Properties UUID definition document [1].
+
+It also may be regarded as the definition of a key and the associated data type
+that can be returned by _DSD in the Device Properties UUID sub-package for a
+given device.
+
+A property set is a collection of properties applicable to a hardware entity
+like a device.  In the ACPI _DSD context it is the set of all properties that
+can be returned in the Device Properties UUID sub-package for the device in
+question.
+
+Property subsets are nested collections of properties.  Each of them is
+associated with an additional key (name) allowing the subset to be referred
+to as a whole (and to be treated as a separate entity).  The canonical
+representation of property subsets is via the mechanism specified in the
+Hierarchical Properties Extension UUID definition document [2].
+
+Property sets may be hierarchical.  That is, a property set may contain
+multiple property subsets that each may contain property subsets of its
+own and so on.
+
+General Validity Rule for Property Sets
+---------------------------------------
+
+Valid property sets must follow the guidance given by the Device Properties UUID
+definition document [1].
+
+_DSD properties are intended to be used in addition to, and not instead of, the
+existing mechanisms defined by the ACPI specification.  Therefore, as a rule,
+they should only be used if the ACPI specification does not make direct
+provisions for handling the underlying use case.  It generally is invalid to
+return property sets which do not follow that rule from _DSD in data packages
+associated with the Device Properties UUID.
+
+Additional Considerations
+-------------------------
+
+There are cases in which, even if the general rule given above is followed in
+principle, the property set may still not be regarded as a valid one.
+
+For example, that applies to device properties which may cause kernel code
+(either a device driver or a library/subsystem) to access hardware in a way
+possibly leading to a conflict with AML methods in the ACPI namespace.  In
+particular, that may happen if the kernel code uses device properties to
+manipulate hardware normally controlled by ACPI methods related to power
+management, like _PSx and _DSW (for device objects) or _ON and _OFF (for power
+resource objects), or by ACPI device disabling/enabling methods, like _DIS and
+_SRS.
+
+In all cases in which kernel code may do something that will confuse AML as a
+result of using device properties, the device properties in question are not
+suitable for the ACPI environment and consequently they cannot belong to a valid
+property set.
+
+Property Sets and Device Tree Bindings
+--------------------------------------
+
+It often is useful to make _DSD return property sets that follow Device Tree
+bindings.
+
+In those cases, however, the above validity considerations must be taken into
+account in the first place and returning invalid property sets from _DSD must be
+avoided.  For this reason, it may not be possible to make _DSD return a property
+set following the given DT binding literally and completely.  Still, for the
+sake of code re-use, it may make sense to provide as much of the configuration
+data as possible in the form of device properties and complement that with an
+ACPI-specific mechanism suitable for the use case at hand.
+
+In any case, property sets following DT bindings literally should not be
+expected to automatically work in the ACPI environment regardless of their
+contents.

+The ACPI _REV method returns the "Revision of the ACPI specification
+that OSPM supports"
+
+This document explains how and why the BIOS and Linux should use these methods.
+It also explains how and why they are widely misused.
+
+How to use _OSI
+---------------
+
+Linux runs on two groups of machines -- those that are tested by the OEM
+to be compatible with Linux, and those that were never tested with Linux,
+but where Linux was installed to replace the original OS (Windows or OSX).
+
+The larger group is the systems tested to run only Windows.  Not only that,
+but many were tested to run with just one specific version of Windows.
+So even though the BIOS may use _OSI to query what version of Windows is running,
+only a single path through the BIOS has actually been tested.
+Experience shows that taking untested paths through the BIOS
+exposes Linux to an entire category of BIOS bugs.
+For this reason, Linux _OSI defaults must continue to claim compatibility
+with all versions of Windows.
+
+But Linux isn't actually compatible with Windows, and the Linux community
+has also been hurt with regressions when Linux adds the latest version of
+Windows to its list of _OSI strings.  So it is possible that additional strings
+will be more thoroughly vetted before shipping upstream in the future.
+But it is likely that they will all eventually be added.
+
+What should an OEM do if they want to support Linux and Windows
+using the same BIOS image?  Often they need to do something different
+for Linux to deal with how Linux is different from Windows.
+Here the BIOS should ask exactly what it wants to know:
+
+_OSI("Linux-OEM-my_interface_name")
+where 'OEM' is needed if this is an OEM-specific hook,
+and 'my_interface_name' describes the hook, which could be a
+quirk, a bug, or a bug-fix.
+
+In addition, the OEM should send a patch to upstream Linux
+via the linux-acpi@vger.kernel.org mailing list.  When that patch
+is checked into Linux, the OS will answer "YES" when the BIOS
+on the OEM's system uses _OSI to ask if the interface is supported
+by the OS.  Linux distributors can back-port that patch for Linux
+pre-installs, and it will be included by all distributions that
+re-base to upstream.  If the distribution can not update the kernel binary,
+they can also add an acpi_osi=Linux-OEM-my_interface_name
+cmdline parameter to the boot loader, as needed.
+
+If the string refers to a feature where the upstream kernel
+eventually grows support, a patch should be sent to remove
+the string when that support is added to the kernel.
+
+That was easy.  Read on, to find out how to do it wrong.
+
+Before _OSI, there was _OS
+--------------------------
+
+ACPI 1.0 specified "_OS" as an
+"object that evaluates to a string that identifies the operating system."
+
+The ACPI BIOS flow would include an evaluation of _OS, and the AML
+interpreter in the kernel would return to it a string identifying the OS:
+
+Windows 98, SE: "Microsoft Windows"
+Windows ME: "Microsoft WindowsME:Millenium Edition"
+Windows NT: "Microsoft Windows NT"
+
+The idea was on a platform tasked with running multiple OS's,
+the BIOS could use _OS to enable devices that an OS
+might support, or enable quirks or bug workarounds
+necessary to make the platform compatible with that pre-existing OS.
+
+But _OS had fundamental problems.  First, the BIOS needed to know the name
+of every possible version of the OS that would run on it, and needed to know
+all the quirks of those OS's.  Certainly it would make more sense
+for the BIOS to ask *specific* things of the OS, such
+"do you support a specific interface", and thus in ACPI 3.0,
+_OSI was born to replace _OS.
+
+_OS was abandoned, though even today, many BIOS look for
+_OS "Microsoft Windows NT", though it seems somewhat far-fetched
+that anybody would install those old operating systems
+over what came with the machine.
+
+Linux answers "Microsoft Windows NT" to please that BIOS idiom.
+That is the *only* viable strategy, as that is what modern Windows does,
+and so doing otherwise could steer the BIOS down an untested path.
+
+_OSI is born, and immediately misused
+--------------------------------------
+
+With _OSI, the *BIOS* provides the string describing an interface,
+and asks the OS: "YES/NO, are you compatible with this interface?"
+
+eg. _OSI("3.0 Thermal Model") would return TRUE if the OS knows how
+to deal with the thermal extensions made to the ACPI 3.0 specification.
+An old OS that doesn't know about those extensions would answer FALSE,
+and a new OS may be able to return TRUE.
+
+For an OS-specific interface, the ACPI spec said that the BIOS and the OS
+were to agree on a string of the form such as "Windows-interface_name".
+
+But two bad things happened.  First, the Windows ecosystem used _OSI
+not as designed, but as a direct replacement for _OS -- identifying
+the OS version, rather than an OS supported interface.  Indeed, right
+from the start, the ACPI 3.0 spec itself codified this misuse
+in example code using _OSI("Windows 2001").
+
+This misuse was adopted and continues today.
+
+Linux had no choice but to also return TRUE to _OSI("Windows 2001")
+and its successors.  To do otherwise would virtually guarantee breaking
+a BIOS that has been tested only with that _OSI returning TRUE.
+
+This strategy is problematic, as Linux is never completely compatible with
+the latest version of Windows, and sometimes it takes more than a year
+to iron out incompatibilities.
+
+Not to be out-done, the Linux community made things worse by returning TRUE
+to _OSI("Linux").  Doing so is even worse than the Windows misuse
+of _OSI, as "Linux" does not even contain any version information.
+_OSI("Linux") led to some BIOS' malfunctioning due to BIOS writer's
+using it in untested BIOS flows.  But some OEM's used _OSI("Linux")
+in tested flows to support real Linux features.  In 2009, Linux
+removed _OSI("Linux"), and added a cmdline parameter to restore it
+for legacy systems still needed it.  Further a BIOS_BUG warning prints
+for all BIOS's that invoke it.
+
+No BIOS should use _OSI("Linux").
+
+The result is a strategy for Linux to maximize compatibility with
+ACPI BIOS that are tested on Windows machines.  There is a real risk
+of over-stating that compatibility; but the alternative has often been
+catastrophic failure resulting from the BIOS taking paths that
+were never validated under *any* OS.
+
+Do not use _REV
+---------------
+
+Since _OSI("Linux") went away, some BIOS writers used _REV
+to support Linux and Windows differences in the same BIOS.
+
+_REV was defined in ACPI 1.0 to return the version of ACPI
+supported by the OS and the OS AML interpreter.
+
+Modern Windows returns _REV = 2.  Linux used ACPI_CA_SUPPORT_LEVEL,
+which would increment, based on the version of the spec supported.
+
+Unfortunately, _REV was also misused.  eg. some BIOS would check
+for _REV = 3, and do something for Linux, but when Linux returned
+_REV = 4, that support broke.
+
+In response to this problem, Linux returns _REV = 2 always,
+from mid-2015 onward.  The ACPI specification will also be updated
+to reflect that _REV is deprecated, and always returns 2.
+
+Apple Mac and _OSI("Darwin")
+----------------------------
+
+On Apple's Mac platforms, the ACPI BIOS invokes _OSI("Darwin")
+to determine if the machine is running Apple OSX.
+
+Like Linux's _OSI("*Windows*") strategy, Linux defaults to
+answering YES to _OSI("Darwin") to enable full access
+to the hardware and validated BIOS paths seen by OSX.
+Just like on Windows-tested platforms, this strategy has risks.
+
+Starting in Linux-3.18, the kernel answered YES to _OSI("Darwin")
+for the purpose of enabling Mac Thunderbolt support.  Further,
+if the kernel noticed _OSI("Darwin") being invoked, it additionally
+disabled all _OSI("*Windows*") to keep poorly written Mac BIOS
+from going down untested combinations of paths.
+
+The Linux-3.18 change in default caused power regressions on Mac
+laptops, and the 3.18 implementation did not allow changing
+the default via cmdline "acpi_osi=!Darwin".  Linux-4.7 fixed
+the ability to use acpi_osi=!Darwin as a workaround, and
+we hope to see Mac Thunderbolt power management support in Linux-4.11.

+Linux kernel release 4.x <http://kernel.org/>
+=============================================
+
+These are the release notes for Linux version 4.  Read them carefully,
+as they tell you what this is all about, explain how to install the
+kernel, and what to do if something goes wrong.
+
+What is Linux?
+--------------
+
+  Linux is a clone of the operating system Unix, written from scratch by
+  Linus Torvalds with assistance from a loosely-knit team of hackers across
+  the Net. It aims towards POSIX and Single UNIX Specification compliance.
+
+  It has all the features you would expect in a modern fully-fledged Unix,
+  including true multitasking, virtual memory, shared libraries, demand
+  loading, shared copy-on-write executables, proper memory management,
+  and multistack networking including IPv4 and IPv6.
+
+  It is distributed under the GNU General Public License - see the
+  accompanying COPYING file for more details.
+
+On what hardware does it run?
+-----------------------------
+
+  Although originally developed first for 32-bit x86-based PCs (386 or higher),
+  today Linux also runs on (at least) the Compaq Alpha AXP, Sun SPARC and
+  UltraSPARC, Motorola 68000, PowerPC, PowerPC64, ARM, Hitachi SuperH, Cell,
+  IBM S/390, MIPS, HP PA-RISC, Intel IA-64, DEC VAX, AMD x86-64, AXIS CRIS,
+  Xtensa, Tilera TILE, AVR32, ARC and Renesas M32R architectures.
+
+  Linux is easily portable to most general-purpose 32- or 64-bit architectures
+  as long as they have a paged memory management unit (PMMU) and a port of the
+  GNU C compiler (gcc) (part of The GNU Compiler Collection, GCC). Linux has
+  also been ported to a number of architectures without a PMMU, although
+  functionality is then obviously somewhat limited.
+  Linux has also been ported to itself. You can now run the kernel as a
+  userspace application - this is called UserMode Linux (UML).
+
+Documentation
+-------------
+
+ - There is a lot of documentation available both in electronic form on
+   the Internet and in books, both Linux-specific and pertaining to
+   general UNIX questions.  I'd recommend looking into the documentation
+   subdirectories on any Linux FTP site for the LDP (Linux Documentation
+   Project) books.  This README is not meant to be documentation on the
+   system: there are much better sources available.
+
+ - There are various README files in the Documentation/ subdirectory:
+   these typically contain kernel-specific installation notes for some
+   drivers for example. See Documentation/00-INDEX for a list of what
+   is contained in each file.  Please read the
+   :ref:`Documentation/process/changes.rst <changes>` file, as it
+   contains information about the problems, which may result by upgrading
+   your kernel.
+
+ - The Documentation/DocBook/ subdirectory contains several guides for
+   kernel developers and users.  These guides can be rendered in a
+   number of formats:  PostScript (.ps), PDF, HTML, & man-pages, among others.
+   After installation, ``make psdocs``, ``make pdfdocs``, ``make htmldocs``,
+   or ``make mandocs`` will render the documentation in the requested format.
+
+Installing the kernel source
+----------------------------
+
+ - If you install the full sources, put the kernel tarball in a
+   directory where you have permissions (e.g. your home directory) and
+   unpack it::
+
+     xz -cd linux-4.X.tar.xz | tar xvf -
+
+   Replace "X" with the version number of the latest kernel.
+
+   Do NOT use the /usr/src/linux area! This area has a (usually
+   incomplete) set of kernel headers that are used by the library header
+   files.  They should match the library, and not get messed up by
+   whatever the kernel-du-jour happens to be.
+
+ - You can also upgrade between 4.x releases by patching.  Patches are
+   distributed in the xz format.  To install by patching, get all the
+   newer patch files, enter the top level directory of the kernel source
+   (linux-4.X) and execute::
+
+     xz -cd ../patch-4.x.xz | patch -p1
+
+   Replace "x" for all versions bigger than the version "X" of your current
+   source tree, **in_order**, and you should be ok.  You may want to remove
+   the backup files (some-file-name~ or some-file-name.orig), and make sure
+   that there are no failed patches (some-file-name# or some-file-name.rej).
+   If there are, either you or I have made a mistake.
+
+   Unlike patches for the 4.x kernels, patches for the 4.x.y kernels
+   (also known as the -stable kernels) are not incremental but instead apply
+   directly to the base 4.x kernel.  For example, if your base kernel is 4.0
+   and you want to apply the 4.0.3 patch, you must not first apply the 4.0.1
+   and 4.0.2 patches. Similarly, if you are running kernel version 4.0.2 and
+   want to jump to 4.0.3, you must first reverse the 4.0.2 patch (that is,
+   patch -R) **before** applying the 4.0.3 patch. You can read more on this in
+   :ref:`Documentation/process/applying-patches.rst <applying_patches>`.
+
+   Alternatively, the script patch-kernel can be used to automate this
+   process.  It determines the current kernel version and applies any
+   patches found::
+
+     linux/scripts/patch-kernel linux
+
+   The first argument in the command above is the location of the
+   kernel source.  Patches are applied from the current directory, but
+   an alternative directory can be specified as the second argument.
+
+ - Make sure you have no stale .o files and dependencies lying around::
+
+     cd linux
+     make mrproper
+
+   You should now have the sources correctly installed.
+
+Software requirements
+---------------------
+
+   Compiling and running the 4.x kernels requires up-to-date
+   versions of various software packages.  Consult
+   :ref:`Documentation/process/changes.rst <changes>` for the minimum version numbers
+   required and how to get updates for these packages.  Beware that using
+   excessively old versions of these packages can cause indirect
+   errors that are very difficult to track down, so don't assume that
+   you can just update packages when obvious problems arise during
+   build or operation.
+
+Build directory for the kernel
+------------------------------
+
+   When compiling the kernel, all output files will per default be
+   stored together with the kernel source code.
+   Using the option ``make O=output/dir`` allows you to specify an alternate
+   place for the output files (including .config).
+   Example::
+
+     kernel source code: /usr/src/linux-4.X
+     build directory:    /home/name/build/kernel
+
+   To configure and build the kernel, use::
+
+     cd /usr/src/linux-4.X
+     make O=/home/name/build/kernel menuconfig
+     make O=/home/name/build/kernel
+     sudo make O=/home/name/build/kernel modules_install install
+
+   Please note: If the ``O=output/dir`` option is used, then it must be
+   used for all invocations of make.
+
+Configuring the kernel
+----------------------
+
+   Do not skip this step even if you are only upgrading one minor
+   version.  New configuration options are added in each release, and
+   odd problems will turn up if the configuration files are not set up
+   as expected.  If you want to carry your existing configuration to a
+   new version with minimal work, use ``make oldconfig``, which will
+   only ask you for the answers to new questions.
+
+ - Alternative configuration commands are::
+
+     "make config"      Plain text interface.
+
+     "make menuconfig"  Text based color menus, radiolists & dialogs.
+
+     "make nconfig"     Enhanced text based color menus.
+
+     "make xconfig"     Qt based configuration tool.
+
+     "make gconfig"     GTK+ based configuration tool.
+
+     "make oldconfig"   Default all questions based on the contents of
+                        your existing ./.config file and asking about
+                        new config symbols.
+
+     "make silentoldconfig"
+                        Like above, but avoids cluttering the screen
+                        with questions already answered.
+                        Additionally updates the dependencies.
+
+     "make olddefconfig"
+                        Like above, but sets new symbols to their default
+                        values without prompting.
+
+     "make defconfig"   Create a ./.config file by using the default
+                        symbol values from either arch/$ARCH/defconfig
+                        or arch/$ARCH/configs/${PLATFORM}_defconfig,
+                        depending on the architecture.
+
+     "make ${PLATFORM}_defconfig"
+                        Create a ./.config file by using the default
+                        symbol values from
+                        arch/$ARCH/configs/${PLATFORM}_defconfig.
+                        Use "make help" to get a list of all available
+                        platforms of your architecture.
+
+     "make allyesconfig"
+                        Create a ./.config file by setting symbol
+                        values to 'y' as much as possible.
+
+     "make allmodconfig"
+                        Create a ./.config file by setting symbol
+                        values to 'm' as much as possible.
+
+     "make allnoconfig" Create a ./.config file by setting symbol
+                        values to 'n' as much as possible.
+
+     "make randconfig"  Create a ./.config file by setting symbol
+                        values to random values.
+
+     "make localmodconfig" Create a config based on current config and
+                           loaded modules (lsmod). Disables any module
+                           option that is not needed for the loaded modules.
+
+                           To create a localmodconfig for another machine,
+                           store the lsmod of that machine into a file
+                           and pass it in as a LSMOD parameter.
+
+                   target$ lsmod > /tmp/mylsmod
+                   target$ scp /tmp/mylsmod host:/tmp
+
+                   host$ make LSMOD=/tmp/mylsmod localmodconfig
+
+                           The above also works when cross compiling.
+
+     "make localyesconfig" Similar to localmodconfig, except it will convert
+                           all module options to built in (=y) options.
+
+   You can find more information on using the Linux kernel config tools
+   in Documentation/kbuild/kconfig.txt.
+
+ - NOTES on ``make config``:
+
+    - Having unnecessary drivers will make the kernel bigger, and can
+      under some circumstances lead to problems: probing for a
+      nonexistent controller card may confuse your other controllers
+
+    - A kernel with math-emulation compiled in will still use the
+      coprocessor if one is present: the math emulation will just
+      never get used in that case.  The kernel will be slightly larger,
+      but will work on different machines regardless of whether they
+      have a math coprocessor or not.
+
+    - The "kernel hacking" configuration details usually result in a
+      bigger or slower kernel (or both), and can even make the kernel
+      less stable by configuring some routines to actively try to
+      break bad code to find kernel problems (kmalloc()).  Thus you
+      should probably answer 'n' to the questions for "development",
+      "experimental", or "debugging" features.
+
+Compiling the kernel
+--------------------
+
+ - Make sure you have at least gcc 3.2 available.
+   For more information, refer to :ref:`Documentation/process/changes.rst <changes>`.
+
+   Please note that you can still run a.out user programs with this kernel.
+
+ - Do a ``make`` to create a compressed kernel image. It is also
+   possible to do ``make install`` if you have lilo installed to suit the
+   kernel makefiles, but you may want to check your particular lilo setup first.
+
+   To do the actual install, you have to be root, but none of the normal
+   build should require that. Don't take the name of root in vain.
+
+ - If you configured any of the parts of the kernel as ``modules``, you
+   will also have to do ``make modules_install``.
+
+ - Verbose kernel compile/build output:
+
+   Normally, the kernel build system runs in a fairly quiet mode (but not
+   totally silent).  However, sometimes you or other kernel developers need
+   to see compile, link, or other commands exactly as they are executed.
+   For this, use "verbose" build mode.  This is done by passing
+   ``V=1`` to the ``make`` command, e.g.::
+
+     make V=1 all
+
+   To have the build system also tell the reason for the rebuild of each
+   target, use ``V=2``.  The default is ``V=0``.
+
+ - Keep a backup kernel handy in case something goes wrong.  This is
+   especially true for the development releases, since each new release
+   contains new code which has not been debugged.  Make sure you keep a
+   backup of the modules corresponding to that kernel, as well.  If you
+   are installing a new kernel with the same version number as your
+   working kernel, make a backup of your modules directory before you
+   do a ``make modules_install``.
+
+   Alternatively, before compiling, use the kernel config option
+   "LOCALVERSION" to append a unique suffix to the regular kernel version.
+   LOCALVERSION can be set in the "General Setup" menu.
+
+ - In order to boot your new kernel, you'll need to copy the kernel
+   image (e.g. .../linux/arch/x86/boot/bzImage after compilation)
+   to the place where your regular bootable kernel is found.
+
+ - Booting a kernel directly from a floppy without the assistance of a
+   bootloader such as LILO, is no longer supported.
+
+   If you boot Linux from the hard drive, chances are you use LILO, which
+   uses the kernel image as specified in the file /etc/lilo.conf.  The
+   kernel image file is usually /vmlinuz, /boot/vmlinuz, /bzImage or
+   /boot/bzImage.  To use the new kernel, save a copy of the old image
+   and copy the new image over the old one.  Then, you MUST RERUN LILO
+   to update the loading map! If you don't, you won't be able to boot
+   the new kernel image.
+
+   Reinstalling LILO is usually a matter of running /sbin/lilo.
+   You may wish to edit /etc/lilo.conf to specify an entry for your
+   old kernel image (say, /vmlinux.old) in case the new one does not
+   work.  See the LILO docs for more information.
+
+   After reinstalling LILO, you should be all set.  Shutdown the system,
+   reboot, and enjoy!
+
+   If you ever need to change the default root device, video mode,
+   ramdisk size, etc.  in the kernel image, use the ``rdev`` program (or
+   alternatively the LILO boot options when appropriate).  No need to
+   recompile the kernel to change these parameters.
+
+ - Reboot with the new kernel and enjoy.
+
+If something goes wrong
+-----------------------
+
+ - If you have problems that seem to be due to kernel bugs, please check
+   the file MAINTAINERS to see if there is a particular person associated
+   with the part of the kernel that you are having trouble with. If there
+   isn't anyone listed there, then the second best thing is to mail
+   them to me (torvalds@linux-foundation.org), and possibly to any other
+   relevant mailing-list or to the newsgroup.
+
+ - In all bug-reports, *please* tell what kernel you are talking about,
+   how to duplicate the problem, and what your setup is (use your common
+   sense).  If the problem is new, tell me so, and if the problem is
+   old, please try to tell me when you first noticed it.
+
+ - If the bug results in a message like::
+
+     unable to handle kernel paging request at address C0000010
+     Oops: 0002

+   or similar kernel debugging information on your screen or in your
+   system log, please duplicate it *exactly*.  The dump may look
+   incomprehensible to you, but it does contain information that may
+   help debugging the problem.  The text above the dump is also
+   important: it tells something about why the kernel dumped code (in
+   the above example, it's due to a bad kernel pointer). More information
+   on making sense of the dump is in Documentation/admin-guide/oops-tracing.rst
+
+ - If you compiled the kernel with CONFIG_KALLSYMS you can send the dump
+   as is, otherwise you will have to use the ``ksymoops`` program to make
+   sense of the dump (but compiling with CONFIG_KALLSYMS is usually preferred).
+   This utility can be downloaded from
+   ftp://ftp.<country>.kernel.org/pub/linux/utils/kernel/ksymoops/ .
+   Alternatively, you can do the dump lookup by hand:
+
+ - In debugging dumps like the above, it helps enormously if you can
+   look up what the EIP value means.  The hex value as such doesn't help
+   me or anybody else very much: it will depend on your particular
+   kernel setup.  What you should do is take the hex value from the EIP
+   line (ignore the ``0010:``), and look it up in the kernel namelist to
+   see which kernel function contains the offending address.
+
+   To find out the kernel function name, you'll need to find the system
+   binary associated with the kernel that exhibited the symptom.  This is
+   the file 'linux/vmlinux'.  To extract the namelist and match it against
+   the EIP from the kernel crash, do::
+
+     nm vmlinux | sort | less
+
+   This will give you a list of kernel addresses sorted in ascending
+   order, from which it is simple to find the function that contains the
+   offending address.  Note that the address given by the kernel
+   debugging messages will not necessarily match exactly with the
+   function addresses (in fact, that is very unlikely), so you can't
+   just 'grep' the list: the list will, however, give you the starting
+   point of each kernel function, so by looking for the function that
+   has a starting address lower than the one you are searching for but
+   is followed by a function with a higher address you will find the one
+   you want.  In fact, it may be a good idea to include a bit of
+   "context" in your problem report, giving a few lines around the
+   interesting one.
+
+   If you for some reason cannot do the above (you have a pre-compiled
+   kernel image or similar), telling me as much about your setup as
+   possible will help.  Please read the :ref:`admin-guide/reporting-bugs.rst <reportingbugs>`
+   document for details.
+
+ - Alternatively, you can use gdb on a running kernel. (read-only; i.e. you
+   cannot change values or set break points.) To do this, first compile the
+   kernel with -g; edit arch/x86/Makefile appropriately, then do a ``make
+   clean``. You'll also need to enable CONFIG_PROC_FS (via ``make config``).
+
+   After you've rebooted with the new kernel, do ``gdb vmlinux /proc/kcore``.
+   You can now use all the usual gdb commands. The command to look up the
+   point where your system crashed is ``l *0xXXXXXXXX``. (Replace the XXXes
+   with the EIP value.)
+
+   gdb'ing a non-running kernel currently fails because ``gdb`` (wrongly)
+   disregards the starting offset for which the kernel is compiled.

+Kernel Support for miscellaneous (your favourite) Binary Formats v1.1
+=====================================================================
+
+This Kernel feature allows you to invoke almost (for restrictions see below)
+every program by simply typing its name in the shell.
+This includes for example compiled Java(TM), Python or Emacs programs.
+
+To achieve this you must tell binfmt_misc which interpreter has to be invoked
+with which binary. Binfmt_misc recognises the binary-type by matching some bytes
+at the beginning of the file with a magic byte sequence (masking out specified
+bits) you have supplied. Binfmt_misc can also recognise a filename extension
+aka ``.com`` or ``.exe``.
+
+First you must mount binfmt_misc::
+
+	mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc
+
+To actually register a new binary type, you have to set up a string looking like
+``:name:type:offset:magic:mask:interpreter:flags`` (where you can choose the
+``:`` upon your needs) and echo it to ``/proc/sys/fs/binfmt_misc/register``.
+
+Here is what the fields mean:
+
+- ``name``
+   is an identifier string. A new /proc file will be created with this
+   ``name below /proc/sys/fs/binfmt_misc``; cannot contain slashes ``/`` for
+   obvious reasons.
+- ``type``
+   is the type of recognition. Give ``M`` for magic and ``E`` for extension.
+- ``offset``
+   is the offset of the magic/mask in the file, counted in bytes. This
+   defaults to 0 if you omit it (i.e. you write ``:name:type::magic...``).
+   Ignored when using filename extension matching.
+- ``magic``
+   is the byte sequence binfmt_misc is matching for. The magic string
+   may contain hex-encoded characters like ``\x0a`` or ``\xA4``. Note that you
+   must escape any NUL bytes; parsing halts at the first one. In a shell
+   environment you might have to write ``\\x0a`` to prevent the shell from
+   eating your ``\``.
+   If you chose filename extension matching, this is the extension to be
+   recognised (without the ``.``, the ``\x0a`` specials are not allowed).
+   Extension    matching is case sensitive, and slashes ``/`` are not allowed!
+- ``mask``
+   is an (optional, defaults to all 0xff) mask. You can mask out some
+   bits from matching by supplying a string like magic and as long as magic.
+   The mask is anded with the byte sequence of the file. Note that you must
+   escape any NUL bytes; parsing halts at the first one. Ignored when using
+   filename extension matching.
+- ``interpreter``
+   is the program that should be invoked with the binary as first
+   argument (specify the full path)
+- ``flags``
+   is an optional field that controls several aspects of the invocation
+   of the interpreter. It is a string of capital letters, each controls a
+   certain aspect. The following flags are supported:
+
+      ``P`` - preserve-argv[0]
+            Legacy behavior of binfmt_misc is to overwrite
+            the original argv[0] with the full path to the binary. When this
+            flag is included, binfmt_misc will add an argument to the argument
+            vector for this purpose, thus preserving the original ``argv[0]``.
+            e.g. If your interp is set to ``/bin/foo`` and you run ``blah``
+            (which is in ``/usr/local/bin``), then the kernel will execute
+            ``/bin/foo`` with ``argv[]`` set to ``["/bin/foo", "/usr/local/bin/blah", "blah"]``.  The interp has to be aware of this so it can
+            execute ``/usr/local/bin/blah``
+            with ``argv[]`` set to ``["blah"]``.
+      ``O`` - open-binary
+	    Legacy behavior of binfmt_misc is to pass the full path
+            of the binary to the interpreter as an argument. When this flag is
+            included, binfmt_misc will open the file for reading and pass its
+            descriptor as an argument, instead of the full path, thus allowing
+            the interpreter to execute non-readable binaries. This feature
+            should be used with care - the interpreter has to be trusted not to
+            emit the contents of the non-readable binary.
+      ``C`` - credentials
+            Currently, the behavior of binfmt_misc is to calculate
+            the credentials and security token of the new process according to
+            the interpreter. When this flag is included, these attributes are
+            calculated according to the binary. It also implies the ``O`` flag.
+            This feature should be used with care as the interpreter
+            will run with root permissions when a setuid binary owned by root
+            is run with binfmt_misc.
+      ``F`` - fix binary
+            The usual behaviour of binfmt_misc is to spawn the
+	    binary lazily when the misc format file is invoked.  However,
+	    this doesn``t work very well in the face of mount namespaces and
+	    changeroots, so the ``F`` mode opens the binary as soon as the
+	    emulation is installed and uses the opened image to spawn the
+	    emulator, meaning it is always available once installed,
+	    regardless of how the environment changes.
+
+
+There are some restrictions:
+
+ - the whole register string may not exceed 1920 characters
+ - the magic must reside in the first 128 bytes of the file, i.e.
+   offset+size(magic) has to be less than 128
+ - the interpreter string may not exceed 127 characters
+
+To use binfmt_misc you have to mount it first. You can mount it with
+``mount -t binfmt_misc none /proc/sys/fs/binfmt_misc`` command, or you can add
+a line ``none  /proc/sys/fs/binfmt_misc binfmt_misc defaults 0 0`` to your
+``/etc/fstab`` so it auto mounts on boot.
+
+You may want to add the binary formats in one of your ``/etc/rc`` scripts during
+boot-up. Read the manual of your init program to figure out how to do this
+right.
+
+Think about the order of adding entries! Later added entries are matched first!
+
+
+A few examples (assumed you are in ``/proc/sys/fs/binfmt_misc``):
+
+- enable support for em86 (like binfmt_em86, for Alpha AXP only)::
+
+    echo ':i386:M::\x7fELF\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x03:\xff\xff\xff\xff\xff\xfe\xfe\xff\xff\xff\xff\xff\xff\xff\xff\xff\xfb\xff\xff:/bin/em86:' > register
+    echo ':i486:M::\x7fELF\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x06:\xff\xff\xff\xff\xff\xfe\xfe\xff\xff\xff\xff\xff\xff\xff\xff\xff\xfb\xff\xff:/bin/em86:' > register
+
+- enable support for packed DOS applications (pre-configured dosemu hdimages)::
+
+    echo ':DEXE:M::\x0eDEX::/usr/bin/dosexec:' > register
+
+- enable support for Windows executables using wine::
+
+    echo ':DOSWin:M::MZ::/usr/local/bin/wine:' > register
+
+For java support see Documentation/admin-guide/java.rst
+
+
+You can enable/disable binfmt_misc or one binary type by echoing 0 (to disable)
+or 1 (to enable) to ``/proc/sys/fs/binfmt_misc/status`` or
+``/proc/.../the_name``.
+Catting the file tells you the current status of ``binfmt_misc/the_entry``.
+
+You can remove one entry or all entries by echoing -1 to ``/proc/.../the_name``
+or ``/proc/sys/fs/binfmt_misc/status``.
+
+
+Hints
+-----
+
+If you want to pass special arguments to your interpreter, you can
+write a wrapper script for it. See Documentation/admin-guide/java.rst for an
+example.
+
+Your interpreter should NOT look in the PATH for the filename; the kernel
+passes it the full filename (or the file descriptor) to use.  Using ``$PATH`` can
+cause unexpected behaviour and can be a security hazard.

+Linux Braille Console
+=====================
+
+To get early boot messages on a braille device (before userspace screen
+readers can start), you first need to compile the support for the usual serial
+console (see :ref:`Documentation/admin-guide/serial-console.rst <serial_console>`), and
+for braille device
+(in :menuselection:`Device Drivers --> Accessibility support --> Console on braille device`).
+
+Then you need to specify a ``console=brl``, option on the kernel command line, the
+format is::
+
+	console=brl,serial_options...
+
+where ``serial_options...`` are the same as described in
+:ref:`Documentation/admin-guide/serial-console.rst <serial_console>`.
+
+So for instance you can use ``console=brl,ttyS0`` if the braille device is connected to the first serial port, and ``console=brl,ttyS0,115200`` to
+override the baud rate to 115200, etc.
+
+By default, the braille device will just show the last kernel message (console
+mode).  To review previous messages, press the Insert key to switch to the VT
+review mode.  In review mode, the arrow keys permit to browse in the VT content,
+:kbd:`PAGE-UP`/:kbd:`PAGE-DOWN` keys go at the top/bottom of the screen, and
+the :kbd:`HOME` key goes back
+to the cursor, hence providing very basic screen reviewing facility.
+
+Sound feedback can be obtained by adding the ``braille_console.sound=1`` kernel
+parameter.
+
+For simplicity, only one braille console can be enabled, other uses of
+``console=brl,...`` will be discarded.  Also note that it does not interfere with
+the console selection mechanism described in
+:ref:`Documentation/admin-guide/serial-console.rst <serial_console>`.
+
+For now, only the VisioBraille device is supported.

+Bisecting a bug
++++++++++++++++
+
+Last updated: 28 October 2016
+
+Introduction
+============
+
+Always try the latest kernel from kernel.org and build from source. If you are
+not confident in doing that please report the bug to your distribution vendor
+instead of to a kernel developer.
+
+Finding bugs is not always easy. Have a go though. If you can't find it don't
+give up. Report as much as you have found to the relevant maintainer. See
+MAINTAINERS for who that is for the subsystem you have worked on.
+
+Before you submit a bug report read
+:ref:`Documentation/admin-guide/reporting-bugs.rst <reportingbugs>`.
+
+Devices not appearing
+=====================
+
+Often this is caused by udev/systemd. Check that first before blaming it
+on the kernel.
+
+Finding patch that caused a bug
+===============================
+
+Using the provided tools with ``git`` makes finding bugs easy provided the bug
+is reproducible.
+
+Steps to do it:
+
+- build the Kernel from its git source
+- start bisect with [#f1]_::
+
+	$ git bisect start
+
+- mark the broken changeset with::
+
+	$ git bisect bad [commit]
+
+- mark a changeset where the code is known to work with::
+
+	$ git bisect good [commit]
+
+- rebuild the Kernel and test
+- interact with git bisect by using either::
+
+	$ git bisect good
+
+  or::
+
+	$ git bisect bad
+
+  depending if the bug happened on the changeset you're testing
+- After some interactions, git bisect will give you the changeset that
+  likely caused the bug.
+
+- For example, if you know that the current version is bad, and version
+  4.8 is good, you could do::
+
+           $ git bisect start
+           $ git bisect bad                 # Current version is bad
+           $ git bisect good v4.8
+
+
+.. [#f1] You can, optionally, provide both good and bad arguments at git
+	 start with ``git bisect start [BAD] [GOOD]``
+
+For further references, please read:
+
+- The man page for ``git-bisect``
+- `Fighting regressions with git bisect <https://www.kernel.org/pub/software/scm/git/docs/git-bisect-lk2009.html>`_
+- `Fully automated bisecting with "git bisect run" <https://lwn.net/Articles/317154>`_

+
+Such stack traces provide enough information to identify the line inside the
+Kernel's source code where the bug happened. Depending on the severity of
+the issue, it may also contain the word **Oops**, as on this one::
+
+	BUG: unable to handle kernel NULL pointer dereference at   (null)
+	IP: [<c06969d4>] iret_exc+0x7d0/0xa59
+	*pdpt = 000000002258a001 *pde = 0000000000000000
+	Oops: 0002 [#1] PREEMPT SMP
+	...
+
+Despite being an **Oops** or some other sort of stack trace, the offended
+line is usually required to identify and handle the bug. Along this chapter,
+we'll refer to "Oops" for all kinds of stack traces that need to be analized.
+
+.. note::
+
+  ``ksymoops`` is useless on 2.6 or upper.  Please use the Oops in its original
+  format (from ``dmesg``, etc).  Ignore any references in this or other docs to
+  "decoding the Oops" or "running it through ksymoops".
+  If you post an Oops from 2.6+ that has been run through ``ksymoops``,
+  people will just tell you to repost it.
+
+Where is the Oops message is located?
+-------------------------------------
+
+Normally the Oops text is read from the kernel buffers by klogd and
+handed to ``syslogd`` which writes it to a syslog file, typically
+``/var/log/messages`` (depends on ``/etc/syslog.conf``). On systems with
+systemd, it may also be stored by the ``journald`` daemon, and accessed
+by running ``journalctl`` command.
+
+Sometimes ``klogd`` dies, in which case you can run ``dmesg > file`` to
+read the data from the kernel buffers and save it.  Or you can
+``cat /proc/kmsg > file``, however you have to break in to stop the transfer,
+``kmsg`` is a "never ending file".
+
+If the machine has crashed so badly that you cannot enter commands or
+the disk is not available then you have three options:
+
+(1) Hand copy the text from the screen and type it in after the machine
+    has restarted.  Messy but it is the only option if you have not
+    planned for a crash. Alternatively, you can take a picture of
+    the screen with a digital camera - not nice, but better than
+    nothing.  If the messages scroll off the top of the console, you
+    may find that booting with a higher resolution (eg, ``vga=791``)
+    will allow you to read more of the text. (Caveat: This needs ``vesafb``,
+    so won't help for 'early' oopses)
+
+(2) Boot with a serial console (see
+    :ref:`Documentation/admin-guide/serial-console.rst <serial_console>`),
+    run a null modem to a second machine and capture the output there
+    using your favourite communication program.  Minicom works well.
+
+(3) Use Kdump (see Documentation/kdump/kdump.txt),
+    extract the kernel ring buffer from old memory with using dmesg
+    gdbmacro in Documentation/kdump/gdbmacros.txt.
+
+Finding the bug's location
+--------------------------
+
+Reporting a bug works best if you point the location of the bug at the
+Kernel source file. There are two methods for doing that. Usually, using
+``gdb`` is easier, but the Kernel should be pre-compiled with debug info.
+
+gdb
+^^^
+
+The GNU debug (``gdb``) is the best way to figure out the exact file and line
+number of the OOPS from the ``vmlinux`` file.
+
+The usage of gdb works best on a kernel compiled with ``CONFIG_DEBUG_INFO``.
+This can be set by running::
+
+  $ ./scripts/config -d COMPILE_TEST -e DEBUG_KERNEL -e DEBUG_INFO
+
+On a kernel compiled with ``CONFIG_DEBUG_INFO``, you can simply copy the
+EIP value from the OOPS::
+
+ EIP:    0060:[<c021e50e>]    Not tainted VLI
+
+And use GDB to translate that to human-readable form::
+
+  $ gdb vmlinux
+  (gdb) l *0xc021e50e
+
+If you don't have ``CONFIG_DEBUG_INFO`` enabled, you use the function
+offset from the OOPS::
+
+ EIP is at vt_ioctl+0xda8/0x1482
+
+And recompile the kernel with ``CONFIG_DEBUG_INFO`` enabled::
+
+  $ ./scripts/config -d COMPILE_TEST -e DEBUG_KERNEL -e DEBUG_INFO
+  $ make vmlinux
+  $ gdb vmlinux
+  (gdb) l *vt_ioctl+0xda8
+  0x1888 is in vt_ioctl (drivers/tty/vt/vt_ioctl.c:293).
+  288	{
+  289		struct vc_data *vc = NULL;
+  290		int ret = 0;
+  291
+  292		console_lock();
+  293		if (VT_BUSY(vc_num))
+  294			ret = -EBUSY;
+  295		else if (vc_num)
+  296			vc = vc_deallocate(vc_num);
+  297		console_unlock();
+
+or, if you want to be more verbose::
+
+  (gdb) p vt_ioctl
+  $1 = {int (struct tty_struct *, unsigned int, unsigned long)} 0xae0 <vt_ioctl>
+  (gdb) l *0xae0+0xda8
+
+You could, instead, use the object file::
+
+  $ make drivers/tty/
+  $ gdb drivers/tty/vt/vt_ioctl.o
+  (gdb) l *vt_ioctl+0xda8
+
+If you have a call trace, such as::
+
+     Call Trace:
+      [<ffffffff8802c8e9>] :jbd:log_wait_commit+0xa3/0xf5
+      [<ffffffff810482d9>] autoremove_wake_function+0x0/0x2e
+      [<ffffffff8802770b>] :jbd:journal_stop+0x1be/0x1ee
+      ...
+
+this shows the problem likely in the :jbd: module. You can load that module
+in gdb and list the relevant code::
+
+  $ gdb fs/jbd/jbd.ko
+  (gdb) l *log_wait_commit+0xa3
+
+.. note::
+
+     You can also do the same for any function call at the stack trace,
+     like this one::
+
+	 [<f80bc9ca>] ? dvb_usb_adapter_frontend_exit+0x3a/0x70 [dvb_usb]
+
+     The position where the above call happened can be seen with::
+
+	$ gdb drivers/media/usb/dvb-usb/dvb-usb.o
+	(gdb) l *dvb_usb_adapter_frontend_exit+0x3a
+
+objdump
+^^^^^^^
+
+To debug a kernel, use objdump and look for the hex offset from the crash
+output to find the valid line of code/assembler. Without debug symbols, you
+will see the assembler code for the routine shown, but if your kernel has
+debug symbols the C code will also be available. (Debug symbols can be enabled
+in the kernel hacking menu of the menu configuration.) For example::
+
+    $ objdump -r -S -l --disassemble net/dccp/ipv4.o
+
+.. note::
+
+   You need to be at the top level of the kernel tree for this to pick up
+   your C files.
+
+If you don't have access to the code you can also debug on some crash dumps
+e.g. crash dump output as shown by Dave Miller::
+
+     EIP is at 	+0x14/0x4c0
+      ...
+     Code: 44 24 04 e8 6f 05 00 00 e9 e8 fe ff ff 8d 76 00 8d bc 27 00 00
+     00 00 55 57  56 53 81 ec bc 00 00 00 8b ac 24 d0 00 00 00 8b 5d 08
+     <8b> 83 3c 01 00 00 89 44  24 14 8b 45 28 85 c0 89 44 24 18 0f 85
+
+     Put the bytes into a "foo.s" file like this:
+
+            .text
+            .globl foo
+     foo:
+            .byte  .... /* bytes from Code: part of OOPS dump */
+
+     Compile it with "gcc -c -o foo.o foo.s" then look at the output of
+     "objdump --disassemble foo.o".
+
+     Output:
+
+     ip_queue_xmit:
+         push       %ebp
+         push       %edi
+         push       %esi
+         push       %ebx
+         sub        $0xbc, %esp
+         mov        0xd0(%esp), %ebp        ! %ebp = arg0 (skb)
+         mov        0x8(%ebp), %ebx         ! %ebx = skb->sk
+         mov        0x13c(%ebx), %eax       ! %eax = inet_sk(sk)->opt
+
+Reporting the bug
+-----------------
+
+Once you find where the bug happened, by inspecting its location,
+you could either try to fix it yourself or report it upstream.
+
+In order to report it upstream, you should identify the mailing list
+used for the development of the affected code. This can be done by using
+the ``get_maintainer.pl`` script.
+
+For example, if you find a bug at the gspca's conex.c file, you can get
+their maintainers with::
+
+	$ ./scripts/get_maintainer.pl -f drivers/media/usb/gspca/sonixj.c
+	Hans Verkuil <hverkuil@xs4all.nl> (odd fixer:GSPCA USB WEBCAM DRIVER,commit_signer:1/1=100%)
+	Mauro Carvalho Chehab <mchehab@kernel.org> (maintainer:MEDIA INPUT INFRASTRUCTURE (V4L/DVB),commit_signer:1/1=100%)
+	Tejun Heo <tj@kernel.org> (commit_signer:1/1=100%)
+	Bhaktipriya Shridhar <bhaktipriya96@gmail.com> (commit_signer:1/1=100%,authored:1/1=100%,added_lines:4/4=100%,removed_lines:9/9=100%)
+	linux-media@vger.kernel.org (open list:GSPCA USB WEBCAM DRIVER)
+	linux-kernel@vger.kernel.org (open list)
+
+Please notice that it will point to:
+
+- The last developers that touched on the source code. On the above example,
+  Tejun and Bhaktipriya (in this specific case, none really envolved on the
+  development of this file);
+- The driver maintainer (Hans Verkuil);
+- The subsystem maintainer (Mauro Carvalho Chehab)
+- The driver and/or subsystem mailing list (linux-media@vger.kernel.org);
+- the Linux Kernel mailing list (linux-kernel@vger.kernel.org).
+
+Usually, the fastest way to have your bug fixed is to report it to mailing
+list used for the development of the code (linux-media ML) copying the driver maintainer (Hans).
+
+If you are totally stumped as to whom to send the report, and
+``get_maintainer.pl`` didn't provide you anything useful, send it to
+linux-kernel@vger.kernel.org.
+
+Thanks for your help in making Linux as stable as humanly possible.
+
+Fixing the bug
+--------------
+
+If you know programming, you could help us by not only reporting the bug,
+but also providing us with a solution. After all open source is about
+sharing what you do and don't you want to be recognised for your genius?
+
+If you decide to take this way, once you have worked out a fix please submit
+it upstream.
+
+Please do read
+ref:`Documentation/process/submitting-patches.rst <submittingpatches>` though
+to help your code get accepted.

+
+Notes on Oops tracing with ``klogd``
+------------------------------------
+
+In order to help Linus and the other kernel developers there has been
+substantial support incorporated into ``klogd`` for processing protection
+faults.  In order to have full support for address resolution at least
+version 1.3-pl3 of the ``sysklogd`` package should be used.
+
+When a protection fault occurs the ``klogd`` daemon automatically
+translates important addresses in the kernel log messages to their
+symbolic equivalents.  This translated kernel message is then
+forwarded through whatever reporting mechanism ``klogd`` is using.  The
+protection fault message can be simply cut out of the message files
+and forwarded to the kernel developers.
+
+Two types of address resolution are performed by ``klogd``.  The first is
+static translation and the second is dynamic translation.  Static
+translation uses the System.map file in much the same manner that
+ksymoops does.  In order to do static translation the ``klogd`` daemon
+must be able to find a system map file at daemon initialization time.
+See the klogd man page for information on how ``klogd`` searches for map
+files.
+
+Dynamic address translation is important when kernel loadable modules
+are being used.  Since memory for kernel modules is allocated from the
+kernel's dynamic memory pools there are no fixed locations for either
+the start of the module or for functions and symbols in the module.
+
+The kernel supports system calls which allow a program to determine
+which modules are loaded and their location in memory.  Using these
+system calls the klogd daemon builds a symbol table which can be used
+to debug a protection fault which occurs in a loadable kernel module.
+
+At the very minimum klogd will provide the name of the module which
+generated the protection fault.  There may be additional symbolic
+information available if the developer of the loadable module chose to
+export symbol information from the module.
+
+Since the kernel module environment can be dynamic there must be a
+mechanism for notifying the ``klogd`` daemon when a change in module
+environment occurs.  There are command line options available which
+allow klogd to signal the currently executing daemon that symbol
+information should be refreshed.  See the ``klogd`` manual page for more
+information.
+
+A patch is included with the sysklogd distribution which modifies the
+``modules-2.0.0`` package to automatically signal klogd whenever a module
+is loaded or unloaded.  Applying this patch provides essentially
+seamless support for debugging protection faults which occur with
+kernel loadable modules.
+
+The following is an example of a protection fault in a loadable module
+processed by ``klogd``::

+Linux allocated devices (4.x+ version)
+======================================
+
+This list is the Linux Device List, the official registry of allocated
+device numbers and ``/dev`` directory nodes for the Linux operating
+system.
+
+The LaTeX version of this document is no longer maintained, nor is
+the document that used to reside at lanana.org.  This version in the
+mainline Linux kernel is the master document.  Updates shall be sent
+as patches to the kernel maintainers (see the
+:ref:`Documentation/process/submitting-patches.rst <submittingpatches>` document).
+Specifically explore the sections titled "CHAR and MISC DRIVERS", and
+"BLOCK LAYER" in the MAINTAINERS file to find the right maintainers
+to involve for character and block devices.
+
+This document is included by reference into the Filesystem Hierarchy
+Standard (FHS).	 The FHS is available from http://www.pathname.com/fhs/.
+
+Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga
+platform only.	Allocations marked (68k/Atari) apply to Linux/68k on
+the Atari platform only.
+
+This document is in the public domain.	The authors requests, however,
+that semantically altered versions are not distributed without
+permission of the authors, assuming the authors can be contacted without
+an unreasonable effort.
+
+
+.. attention::
+
+  DEVICE DRIVERS AUTHORS PLEASE READ THIS
+
+  Linux now has extensive support for dynamic allocation of device numbering
+  and can use ``sysfs`` and ``udev`` (``systemd``) to handle the naming needs.
+  There are still some exceptions in the serial and boot device area. Before
+  asking   for a device number make sure you actually need one.
+
+  To have a major number allocated, or a minor number in situations
+  where that applies (e.g. busmice), please submit a patch and send to
+  the authors as indicated above.
+
+  Keep the description of the device *in the same format
+  as this list*. The reason for this is that it is the only way we have
+  found to ensure we have all the requisite information to publish your
+  device and avoid conflicts.
+
+  Finally, sometimes we have to play "namespace police."  Please don't be
+  offended.  We often get submissions for ``/dev`` names that would be bound
+  to cause conflicts down the road.  We are trying to avoid getting in a
+  situation where we would have to suffer an incompatible forward
+  change.  Therefore, please consult with us **before** you make your
+  device names and numbers in any way public, at least to the point
+  where it would be at all difficult to get them changed.
+
+  Your cooperation is appreciated.

+
+Additional ``/dev/`` directory entries
+--------------------------------------
+
+This section details additional entries that should or may exist in
+the /dev directory.  It is preferred that symbolic links use the same
+form (absolute or relative) as is indicated here.  Links are
+classified as "hard" or "symbolic" depending on the preferred type of
+link; if possible, the indicated type of link should be used.
+
+Compulsory links
+++++++++++++++++
+
+These links should exist on all systems:
+
+=============== =============== =============== ===============================
+/dev/fd		/proc/self/fd	symbolic	File descriptors
+/dev/stdin	fd/0		symbolic	stdin file descriptor
+/dev/stdout	fd/1		symbolic	stdout file descriptor
+/dev/stderr	fd/2		symbolic	stderr file descriptor
+/dev/nfsd	socksys		symbolic	Required by iBCS-2
+/dev/X0R	null		symbolic	Required by iBCS-2
+=============== =============== =============== ===============================
+
+Note: ``/dev/X0R`` is <letter X>-<digit 0>-<letter R>.
+
+Recommended links
++++++++++++++++++
+
+It is recommended that these links exist on all systems:
+
+
+=============== =============== =============== ===============================
+/dev/core	/proc/kcore	symbolic	Backward compatibility
+/dev/ramdisk	ram0		symbolic	Backward compatibility
+/dev/ftape	qft0		symbolic	Backward compatibility
+/dev/bttv0	video0		symbolic	Backward compatibility
+/dev/radio	radio0		symbolic	Backward compatibility
+/dev/i2o*	/dev/i2o/*	symbolic	Backward compatibility
+/dev/scd?	sr?		hard		Alternate SCSI CD-ROM name
+=============== =============== =============== ===============================
+
+Locally defined links
++++++++++++++++++++++
+
+The following links may be established locally to conform to the
+configuration of the system.  This is merely a tabulation of existing
+practice, and does not constitute a recommendation.  However, if they
+exist, they should have the following uses.
+
+=============== =============== =============== ===============================
+/dev/mouse	mouse port	symbolic	Current mouse device
+/dev/tape	tape device	symbolic	Current tape device
+/dev/cdrom	CD-ROM device	symbolic	Current CD-ROM device
+/dev/cdwriter	CD-writer	symbolic	Current CD-writer device
+/dev/scanner	scanner		symbolic	Current scanner device
+/dev/modem	modem port	symbolic	Current dialout device
+/dev/root	root device	symbolic	Current root filesystem
+/dev/swap	swap device	symbolic	Current swap device
+=============== =============== =============== ===============================
+
+``/dev/modem`` should not be used for a modem which supports dialin as
+well as dialout, as it tends to cause lock file problems.  If it
+exists, ``/dev/modem`` should point to the appropriate primary TTY device
+(the use of the alternate callout devices is deprecated).
+
+For SCSI devices, ``/dev/tape`` and ``/dev/cdrom`` should point to the
+*cooked* devices (``/dev/st*`` and ``/dev/sr*``, respectively), whereas
+``/dev/cdwriter`` and /dev/scanner should point to the appropriate generic
+SCSI devices (/dev/sg*).
+
+``/dev/mouse`` may point to a primary serial TTY device, a hardware mouse
+device, or a socket for a mouse driver program (e.g. ``/dev/gpmdata``).
+
+Sockets and pipes
++++++++++++++++++
+
+Non-transient sockets and named pipes may exist in /dev.  Common entries are:
+
+=============== =============== ===============================================
+/dev/printer	socket		lpd local socket
+/dev/log	socket		syslog local socket
+/dev/gpmdata	socket		gpm mouse multiplexer
+=============== =============== ===============================================
+
+Mount points
+++++++++++++
+
+The following names are reserved for mounting special filesystems
+under /dev.  These special filesystems provide kernel interfaces that
+cannot be provided with standard device nodes.
+
+=============== =============== ===============================================
+/dev/pts	devpts		PTY slave filesystem
+/dev/shm	tmpfs		POSIX shared memory maintenance access
+=============== =============== ===============================================
+
+Terminal devices
+----------------
+
+Terminal, or TTY devices are a special class of character devices.  A
+terminal device is any device that could act as a controlling terminal
+for a session; this includes virtual consoles, serial ports, and
+pseudoterminals (PTYs).
+
+All terminal devices share a common set of capabilities known as line
+disciplines; these include the common terminal line discipline as well
+as SLIP and PPP modes.
+
+All terminal devices are named similarly; this section explains the
+naming and use of the various types of TTYs.  Note that the naming
+conventions include several historical warts; some of these are
+Linux-specific, some were inherited from other systems, and some
+reflect Linux outgrowing a borrowed convention.
+
+A hash mark (``#``) in a device name is used here to indicate a decimal
+number without leading zeroes.
+
+Virtual consoles and the console device
++++++++++++++++++++++++++++++++++++++++
+
+Virtual consoles are full-screen terminal displays on the system video
+monitor.  Virtual consoles are named ``/dev/tty#``, with numbering
+starting at ``/dev/tty1``; ``/dev/tty0`` is the current virtual console.
+``/dev/tty0`` is the device that should be used to access the system video
+card on those architectures for which the frame buffer devices
+(``/dev/fb*``) are not applicable. Do not use ``/dev/console``
+for this purpose.
+
+The console device, ``/dev/console``, is the device to which system
+messages should be sent, and on which logins should be permitted in
+single-user mode.  Starting with Linux 2.1.71, ``/dev/console`` is managed
+by the kernel; for previous versions it should be a symbolic link to
+either ``/dev/tty0``, a specific virtual console such as ``/dev/tty1``, or to
+a serial port primary (``tty*``, not ``cu*``) device, depending on the
+configuration of the system.
+
+Serial ports
+++++++++++++
+
+Serial ports are RS-232 serial ports and any device which simulates
+one, either in hardware (such as internal modems) or in software (such
+as the ISDN driver.)  Under Linux, each serial ports has two device
+names, the primary or callin device and the alternate or callout one.
+Each kind of device is indicated by a different letter.	 For any
+letter X, the names of the devices are ``/dev/ttyX#`` and ``/dev/cux#``,
+respectively; for historical reasons, ``/dev/ttyS#`` and ``/dev/ttyC#``
+correspond to ``/dev/cua#`` and ``/dev/cub#``. In the future, it should be
+expected that multiple letters will be used; all letters will be upper
+case for the "tty" device (e.g. ``/dev/ttyDP#``) and lower case for the
+"cu" device (e.g. ``/dev/cudp#``).
+
+The names ``/dev/ttyQ#`` and ``/dev/cuq#`` are reserved for local use.
+
+The alternate devices provide for kernel-based exclusion and somewhat
+different defaults than the primary devices.  Their main purpose is to
+allow the use of serial ports with programs with no inherent or broken
+support for serial ports.  Their use is deprecated, and they may be
+removed from a future version of Linux.
+
+Arbitration of serial ports is provided by the use of lock files with
+the names ``/var/lock/LCK..ttyX#``. The contents of the lock file should
+be the PID of the locking process as an ASCII number.
+
+It is common practice to install links such as /dev/modem
+which point to serial ports.  In order to ensure proper locking in the
+presence of these links, it is recommended that software chase
+symlinks and lock all possible names; additionally, it is recommended
+that a lock file be installed with the corresponding alternate
+device.	 In order to avoid deadlocks, it is recommended that the locks
+are acquired in the following order, and released in the reverse:
+
+	1. The symbolic link name, if any (``/var/lock/LCK..modem``)
+	2. The "tty" name (``/var/lock/LCK..ttyS2``)
+	3. The alternate device name (``/var/lock/LCK..cua2``)
+
+In the case of nested symbolic links, the lock files should be
+installed in the order the symlinks are resolved.
+
+Under no circumstances should an application hold a lock while waiting
+for another to be released.  In addition, applications which attempt
+to create lock files for the corresponding alternate device names
+should take into account the possibility of being used on a non-serial
+port TTY, for which no alternate device would exist.
+
+Pseudoterminals (PTYs)
+++++++++++++++++++++++
+
+Pseudoterminals, or PTYs, are used to create login sessions or provide
+other capabilities requiring a TTY line discipline (including SLIP or
+PPP capability) to arbitrary data-generation processes.	 Each PTY has
+a master side, named ``/dev/pty[p-za-e][0-9a-f]``, and a slave side, named
+``/dev/tty[p-za-e][0-9a-f]``.  The kernel arbitrates the use of PTYs by
+allowing each master side to be opened only once.
+
+Once the master side has been opened, the corresponding slave device
+can be used in the same manner as any TTY device.  The master and
+slave devices are connected by the kernel, generating the equivalent
+of a bidirectional pipe with TTY capabilities.
+
+Recent versions of the Linux kernels and GNU libc contain support for
+the System V/Unix98 naming scheme for PTYs, which assigns a common
+device, ``/dev/ptmx``, to all the masters (opening it will automatically
+give you a previously unassigned PTY) and a subdirectory, ``/dev/pts``,
+for the slaves; the slaves are named with decimal integers (``/dev/pts/#``
+in our notation).  This removes the problem of exhausting the
+namespace and enables the kernel to automatically create the device
+nodes for the slaves on demand using the "devpts" filesystem.

-	  **** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****
-
-Linux now has extensive support for dynamic allocation of device numbering
-and can use sysfs and udev (systemd) to handle the naming needs. There are
-still some exceptions in the serial and boot device area. Before asking
-for a device number make sure you actually need one.
-
-To have a major number allocated, or a minor number in situations
-where that applies (e.g. busmice), please submit a patch and send to
-the authors as indicated above.
-
-Keep the description of the device *in the same format
-as this list*.	The reason for this is that it is the only way we have
-found to ensure we have all the requisite information to publish your
-device and avoid conflicts.
-
-Finally, sometimes we have to play "namespace police."  Please don't be
-offended.  We often get submissions for /dev names that would be bound
-to cause conflicts down the road.  We are trying to avoid getting in a
-situation where we would have to suffer an incompatible forward
-change.  Therefore, please consult with us *before* you make your
-device names and numbers in any way public, at least to the point
-where it would be at all difficult to get them changed.
-
-Your cooperation is appreciated.

- ****	ADDITIONAL /dev DIRECTORY ENTRIES
-
-This section details additional entries that should or may exist in
-the /dev directory.  It is preferred that symbolic links use the same
-form (absolute or relative) as is indicated here.  Links are
-classified as "hard" or "symbolic" depending on the preferred type of
-link; if possible, the indicated type of link should be used.
-
-
-	Compulsory links
-
-These links should exist on all systems:
-
-/dev/fd		/proc/self/fd	symbolic	File descriptors
-/dev/stdin	fd/0		symbolic	stdin file descriptor
-/dev/stdout	fd/1		symbolic	stdout file descriptor
-/dev/stderr	fd/2		symbolic	stderr file descriptor
-/dev/nfsd	socksys		symbolic	Required by iBCS-2
-/dev/X0R	null		symbolic	Required by iBCS-2
-
-Note: /dev/X0R is <letter X>-<digit 0>-<letter R>.
-
-	Recommended links
-
-It is recommended that these links exist on all systems:
-
-/dev/core	/proc/kcore	symbolic	Backward compatibility
-/dev/ramdisk	ram0		symbolic	Backward compatibility
-/dev/ftape	qft0		symbolic	Backward compatibility

-/dev/scd?	sr?		hard		Alternate SCSI CD-ROM name
-
-	Locally defined links
-
-The following links may be established locally to conform to the
-configuration of the system.  This is merely a tabulation of existing
-practice, and does not constitute a recommendation.  However, if they
-exist, they should have the following uses.
-
-/dev/mouse	mouse port	symbolic	Current mouse device
-/dev/tape	tape device	symbolic	Current tape device
-/dev/cdrom	CD-ROM device	symbolic	Current CD-ROM device
-/dev/cdwriter	CD-writer	symbolic	Current CD-writer device
-/dev/scanner	scanner		symbolic	Current scanner device
-/dev/modem	modem port	symbolic	Current dialout device
-/dev/root	root device	symbolic	Current root filesystem
-/dev/swap	swap device	symbolic	Current swap device
-
-/dev/modem should not be used for a modem which supports dialin as
-well as dialout, as it tends to cause lock file problems.  If it
-exists, /dev/modem should point to the appropriate primary TTY device
-(the use of the alternate callout devices is deprecated).
-
-For SCSI devices, /dev/tape and /dev/cdrom should point to the
-``cooked'' devices (/dev/st* and /dev/sr*, respectively), whereas
-/dev/cdwriter and /dev/scanner should point to the appropriate generic
-SCSI devices (/dev/sg*).
-
-/dev/mouse may point to a primary serial TTY device, a hardware mouse
-device, or a socket for a mouse driver program (e.g. /dev/gpmdata).
-
-	Sockets and pipes
-
-Non-transient sockets and named pipes may exist in /dev.  Common entries are:
-
-/dev/printer	socket		lpd local socket
-/dev/log	socket		syslog local socket
-/dev/gpmdata	socket		gpm mouse multiplexer
-
-	Mount points
-
-The following names are reserved for mounting special filesystems
-under /dev.  These special filesystems provide kernel interfaces that
-cannot be provided with standard device nodes.
-
-/dev/pts	devpts		PTY slave filesystem
-/dev/shm	tmpfs		POSIX shared memory maintenance access
-
- ****	TERMINAL DEVICES
-
-Terminal, or TTY devices are a special class of character devices.  A
-terminal device is any device that could act as a controlling terminal
-for a session; this includes virtual consoles, serial ports, and
-pseudoterminals (PTYs).
-
-All terminal devices share a common set of capabilities known as line
-disciplines; these include the common terminal line discipline as well
-as SLIP and PPP modes.
-
-All terminal devices are named similarly; this section explains the
-naming and use of the various types of TTYs.  Note that the naming
-conventions include several historical warts; some of these are
-Linux-specific, some were inherited from other systems, and some
-reflect Linux outgrowing a borrowed convention.
-
-A hash mark (#) in a device name is used here to indicate a decimal
-number without leading zeroes.
-
-	Virtual consoles and the console device
-
-Virtual consoles are full-screen terminal displays on the system video
-monitor.  Virtual consoles are named /dev/tty#, with numbering
-starting at /dev/tty1; /dev/tty0 is the current virtual console.
-/dev/tty0 is the device that should be used to access the system video
-card on those architectures for which the frame buffer devices
-(/dev/fb*) are not applicable.	Do not use /dev/console
-for this purpose.
-
-The console device, /dev/console, is the device to which system
-messages should be sent, and on which logins should be permitted in
-single-user mode.  Starting with Linux 2.1.71, /dev/console is managed
-by the kernel; for previous versions it should be a symbolic link to
-either /dev/tty0, a specific virtual console such as /dev/tty1, or to
-a serial port primary (tty*, not cu*) device, depending on the
-configuration of the system.
-
-	Serial ports
-
-Serial ports are RS-232 serial ports and any device which simulates
-one, either in hardware (such as internal modems) or in software (such
-as the ISDN driver.)  Under Linux, each serial ports has two device
-names, the primary or callin device and the alternate or callout one.
-Each kind of device is indicated by a different letter.	 For any
-letter X, the names of the devices are /dev/ttyX# and /dev/cux#,
-respectively; for historical reasons, /dev/ttyS# and /dev/ttyC#
-correspond to /dev/cua# and /dev/cub#.	In the future, it should be
-expected that multiple letters will be used; all letters will be upper
-case for the "tty" device (e.g. /dev/ttyDP#) and lower case for the
-"cu" device (e.g. /dev/cudp#).
-
-The names /dev/ttyQ# and /dev/cuq# are reserved for local use.
-
-The alternate devices provide for kernel-based exclusion and somewhat
-different defaults than the primary devices.  Their main purpose is to
-allow the use of serial ports with programs with no inherent or broken
-support for serial ports.  Their use is deprecated, and they may be
-removed from a future version of Linux.
-
-Arbitration of serial ports is provided by the use of lock files with
-the names /var/lock/LCK..ttyX#.	 The contents of the lock file should
-be the PID of the locking process as an ASCII number.
-
-It is common practice to install links such as /dev/modem
-which point to serial ports.  In order to ensure proper locking in the
-presence of these links, it is recommended that software chase
-symlinks and lock all possible names; additionally, it is recommended
-that a lock file be installed with the corresponding alternate
-device.	 In order to avoid deadlocks, it is recommended that the locks
-are acquired in the following order, and released in the reverse:
-
-	1. The symbolic link name, if any (/var/lock/LCK..modem)
-	2. The "tty" name (/var/lock/LCK..ttyS2)
-	3. The alternate device name (/var/lock/LCK..cua2)
-
-In the case of nested symbolic links, the lock files should be
-installed in the order the symlinks are resolved.
-
-Under no circumstances should an application hold a lock while waiting
-for another to be released.  In addition, applications which attempt
-to create lock files for the corresponding alternate device names
-should take into account the possibility of being used on a non-serial
-port TTY, for which no alternate device would exist.
-
-	Pseudoterminals (PTYs)
-
-Pseudoterminals, or PTYs, are used to create login sessions or provide
-other capabilities requiring a TTY line discipline (including SLIP or
-PPP capability) to arbitrary data-generation processes.	 Each PTY has
-a master side, named /dev/pty[p-za-e][0-9a-f], and a slave side, named
-/dev/tty[p-za-e][0-9a-f].  The kernel arbitrates the use of PTYs by
-allowing each master side to be opened only once.
-
-Once the master side has been opened, the corresponding slave device
-can be used in the same manner as any TTY device.  The master and
-slave devices are connected by the kernel, generating the equivalent
-of a bidirectional pipe with TTY capabilities.
-
-Recent versions of the Linux kernels and GNU libc contain support for
-the System V/Unix98 naming scheme for PTYs, which assigns a common
-device, /dev/ptmx, to all the masters (opening it will automatically
-give you a previously unassigned PTY) and a subdirectory, /dev/pts,
-for the slaves; the slaves are named with decimal integers (/dev/pts/#
-in our notation).  This removes the problem of exhausting the
-namespace and enables the kernel to automatically create the device
-nodes for the slaves on demand using the "devpts" filesystem.

+Dynamic debug
++++++++++++++
+
+
+Introduction
+============
+
+This document describes how to use the dynamic debug (dyndbg) feature.
+
+Dynamic debug is designed to allow you to dynamically enable/disable
+kernel code to obtain additional kernel information.  Currently, if
+``CONFIG_DYNAMIC_DEBUG`` is set, then all ``pr_debug()``/``dev_dbg()`` and
+``print_hex_dump_debug()``/``print_hex_dump_bytes()`` calls can be dynamically
+enabled per-callsite.
+
+If ``CONFIG_DYNAMIC_DEBUG`` is not set, ``print_hex_dump_debug()`` is just
+shortcut for ``print_hex_dump(KERN_DEBUG)``.
+
+For ``print_hex_dump_debug()``/``print_hex_dump_bytes()``, format string is
+its ``prefix_str`` argument, if it is constant string; or ``hexdump``
+in case ``prefix_str`` is build dynamically.
+
+Dynamic debug has even more useful features:
+
+ * Simple query language allows turning on and off debugging
+   statements by matching any combination of 0 or 1 of:
+
+   - source filename
+   - function name
+   - line number (including ranges of line numbers)
+   - module name
+   - format string
+
+ * Provides a debugfs control file: ``<debugfs>/dynamic_debug/control``
+   which can be read to display the complete list of known debug
+   statements, to help guide you
+
+Controlling dynamic debug Behaviour
+===================================
+
+The behaviour of ``pr_debug()``/``dev_dbg()`` are controlled via writing to a
+control file in the 'debugfs' filesystem. Thus, you must first mount
+the debugfs filesystem, in order to make use of this feature.
+Subsequently, we refer to the control file as:
+``<debugfs>/dynamic_debug/control``. For example, if you want to enable
+printing from source file ``svcsock.c``, line 1603 you simply do::
+
+  nullarbor:~ # echo 'file svcsock.c line 1603 +p' >
+				<debugfs>/dynamic_debug/control
+
+If you make a mistake with the syntax, the write will fail thus::
+
+  nullarbor:~ # echo 'file svcsock.c wtf 1 +p' >
+				<debugfs>/dynamic_debug/control
+  -bash: echo: write error: Invalid argument
+
+Viewing Dynamic Debug Behaviour
+===============================
+
+You can view the currently configured behaviour of all the debug
+statements via::
+
+  nullarbor:~ # cat <debugfs>/dynamic_debug/control
+  # filename:lineno [module]function flags format
+  /usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:323 [svcxprt_rdma]svc_rdma_cleanup =_ "SVCRDMA Module Removed, deregister RPC RDMA transport\012"
+  /usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:341 [svcxprt_rdma]svc_rdma_init =_ "\011max_inline       : %d\012"
+  /usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:340 [svcxprt_rdma]svc_rdma_init =_ "\011sq_depth         : %d\012"
+  /usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:338 [svcxprt_rdma]svc_rdma_init =_ "\011max_requests     : %d\012"
+  ...
+
+
+You can also apply standard Unix text manipulation filters to this
+data, e.g.::
+
+  nullarbor:~ # grep -i rdma <debugfs>/dynamic_debug/control  | wc -l
+  62
+
+  nullarbor:~ # grep -i tcp <debugfs>/dynamic_debug/control | wc -l
+  42
+
+The third column shows the currently enabled flags for each debug
+statement callsite (see below for definitions of the flags).  The
+default value, with no flags enabled, is ``=_``.  So you can view all
+the debug statement callsites with any non-default flags::
+
+  nullarbor:~ # awk '$3 != "=_"' <debugfs>/dynamic_debug/control
+  # filename:lineno [module]function flags format
+  /usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svcsock.c:1603 [sunrpc]svc_send p "svc_process: st_sendto returned %d\012"
+
+Command Language Reference
+==========================
+
+At the lexical level, a command comprises a sequence of words separated
+by spaces or tabs.  So these are all equivalent::
+
+  nullarbor:~ # echo -c 'file svcsock.c line 1603 +p' >
+				<debugfs>/dynamic_debug/control
+  nullarbor:~ # echo -c '  file   svcsock.c     line  1603 +p  ' >
+				<debugfs>/dynamic_debug/control
+  nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
+				<debugfs>/dynamic_debug/control
+
+Command submissions are bounded by a write() system call.
+Multiple commands can be written together, separated by ``;`` or ``\n``::
+
+  ~# echo "func pnpacpi_get_resources +p; func pnp_assign_mem +p" \
+     > <debugfs>/dynamic_debug/control
+
+If your query set is big, you can batch them too::
+
+  ~# cat query-batch-file > <debugfs>/dynamic_debug/control
+
+A another way is to use wildcard. The match rule support ``*`` (matches
+zero or more characters) and ``?`` (matches exactly one character).For
+example, you can match all usb drivers::
+
+  ~# echo "file drivers/usb/* +p" > <debugfs>/dynamic_debug/control
+
+At the syntactical level, a command comprises a sequence of match
+specifications, followed by a flags change specification::
+
+  command ::= match-spec* flags-spec
+
+The match-spec's are used to choose a subset of the known pr_debug()
+callsites to which to apply the flags-spec.  Think of them as a query
+with implicit ANDs between each pair.  Note that an empty list of
+match-specs will select all debug statement callsites.
+
+A match specification comprises a keyword, which controls the
+attribute of the callsite to be compared, and a value to compare
+against.  Possible keywords are:::
+
+  match-spec ::= 'func' string |
+		 'file' string |
+		 'module' string |
+		 'format' string |
+		 'line' line-range
+
+  line-range ::= lineno |
+		 '-'lineno |
+		 lineno'-' |
+		 lineno'-'lineno
+
+  lineno ::= unsigned-int
+
+.. note::
+
+  ``line-range`` cannot contain space, e.g.
+  "1-30" is valid range but "1 - 30" is not.
+
+
+The meanings of each keyword are:
+
+func
+    The given string is compared against the function name
+    of each callsite.  Example::
+
+	func svc_tcp_accept
+
+file
+    The given string is compared against either the full pathname, the
+    src-root relative pathname, or the basename of the source file of
+    each callsite.  Examples::
+
+	file svcsock.c
+	file kernel/freezer.c
+	file /usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svcsock.c
+
+module
+    The given string is compared against the module name
+    of each callsite.  The module name is the string as
+    seen in ``lsmod``, i.e. without the directory or the ``.ko``
+    suffix and with ``-`` changed to ``_``.  Examples::
+
+	module sunrpc
+	module nfsd
+
+format
+    The given string is searched for in the dynamic debug format
+    string.  Note that the string does not need to match the
+    entire format, only some part.  Whitespace and other
+    special characters can be escaped using C octal character
+    escape ``\ooo`` notation, e.g. the space character is ``\040``.
+    Alternatively, the string can be enclosed in double quote
+    characters (``"``) or single quote characters (``'``).
+    Examples::
+
+	format svcrdma:         // many of the NFS/RDMA server pr_debugs
+	format readahead        // some pr_debugs in the readahead cache

+    The given line number or range of line numbers is compared

+    and last line number inclusive.  An empty first number means
+    the first line in the file, an empty line number means the
+    last number in the file.  Examples::

+	line 1603           // exactly line 1603

+The flags specification comprises a change operation followed
+by one or more flag characters.  The change operation is one
+of the characters::
+
+  -    remove the given flags
+  +    add the given flags
+  =    set the flags to the given flags
+
+The flags are::
+
+  p    enables the pr_debug() callsite.
+  f    Include the function name in the printed message
+  l    Include line number in the printed message
+  m    Include module name in the printed message
+  t    Include thread ID in messages not generated from interrupt context
+  _    No flags are set. (Or'd with others on input)
+
+For ``print_hex_dump_debug()`` and ``print_hex_dump_bytes()``, only ``p`` flag
+have meaning, other flags ignored.
+
+For display, the flags are preceded by ``=``
+(mnemonic: what the flags are currently equal to).
+
+Note the regexp ``^[-+=][flmpt_]+$`` matches a flags specification.
+To clear all flags at once, use ``=_`` or ``-flmpt``.
+
+
+Debug messages during Boot Process
+==================================
+
+To activate debug messages for core code and built-in modules during
+the boot process, even before userspace and debugfs exists, use
+``dyndbg="QUERY"``, ``module.dyndbg="QUERY"``, or ``ddebug_query="QUERY"``
+(``ddebug_query`` is obsoleted by ``dyndbg``, and deprecated).  QUERY follows
+the syntax described above, but must not exceed 1023 characters.  Your
+bootloader may impose lower limits.
+
+These ``dyndbg`` params are processed just after the ddebug tables are
+processed, as part of the arch_initcall.  Thus you can enable debug
+messages in all code run after this arch_initcall via this boot
+parameter.
+
+On an x86 system for example ACPI enablement is a subsys_initcall and::
+
+   dyndbg="file ec.c +p"
+
+will show early Embedded Controller transactions during ACPI setup if
+your machine (typically a laptop) has an Embedded Controller.
+PCI (or other devices) initialization also is a hot candidate for using
+this boot parameter for debugging purposes.
+
+If ``foo`` module is not built-in, ``foo.dyndbg`` will still be processed at
+boot time, without effect, but will be reprocessed when module is
+loaded later. ``dyndbg_query=`` and bare ``dyndbg=`` are only processed at
+boot.
+
+
+Debug Messages at Module Initialization Time
+============================================
+
+When ``modprobe foo`` is called, modprobe scans ``/proc/cmdline`` for
+``foo.params``, strips ``foo.``, and passes them to the kernel along with
+params given in modprobe args or ``/etc/modprob.d/*.conf`` files,
+in the following order:
+
+1. parameters given via ``/etc/modprobe.d/*.conf``::
+
+	options foo dyndbg=+pt
+	options foo dyndbg # defaults to +p
+
+2. ``foo.dyndbg`` as given in boot args, ``foo.`` is stripped and passed::
+
+	foo.dyndbg=" func bar +p; func buz +mp"
+
+3. args to modprobe::
+
+	modprobe foo dyndbg==pmf # override previous settings
+
+These ``dyndbg`` queries are applied in order, with last having final say.
+This allows boot args to override or modify those from ``/etc/modprobe.d``
+(sensible, since 1 is system wide, 2 is kernel or boot specific), and
+modprobe args to override both.
+
+In the ``foo.dyndbg="QUERY"`` form, the query must exclude ``module foo``.
+``foo`` is extracted from the param-name, and applied to each query in
+``QUERY``, and only 1 match-spec of each type is allowed.
+
+The ``dyndbg`` option is a "fake" module parameter, which means:
+
+- modules do not need to define it explicitly
+- every module gets it tacitly, whether they use pr_debug or not
+- it doesn't appear in ``/sys/module/$module/parameters/``
+  To see it, grep the control file, or inspect ``/proc/cmdline.``
+
+For ``CONFIG_DYNAMIC_DEBUG`` kernels, any settings given at boot-time (or
+enabled by ``-DDEBUG`` flag during compilation) can be disabled later via
+the sysfs interface if the debug messages are no longer needed::
+
+   echo "module module_name -p" > <debugfs>/dynamic_debug/control
+
+Examples
+========
+
+::
+
+  // enable the message at line 1603 of file svcsock.c
+  nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >

+The kernel's command-line parameters
+====================================
+
+The following is a consolidated list of the kernel parameters as
+implemented by the __setup(), core_param() and module_param() macros
+and sorted into English Dictionary order (defined as ignoring all
+punctuation and sorting digits before letters in a case insensitive
+manner), and with descriptions where known.
+
+The kernel parses parameters from the kernel command line up to "--";
+if it doesn't recognize a parameter and it doesn't contain a '.', the
+parameter gets passed to init: parameters with '=' go into init's
+environment, others are passed as command line arguments to init.
+Everything after "--" is passed as an argument to init.
+
+Module parameters can be specified in two ways: via the kernel command
+line with a module name prefix, or via modprobe, e.g.::
+
+	(kernel command line) usbcore.blinkenlights=1
+	(modprobe command line) modprobe usbcore blinkenlights=1
+
+Parameters for modules which are built into the kernel need to be
+specified on the kernel command line.  modprobe looks through the
+kernel command line (/proc/cmdline) and collects module parameters
+when it loads a module, so the kernel command line can be used for
+loadable modules too.
+
+Hyphens (dashes) and underscores are equivalent in parameter names, so::
+
+	log_buf_len=1M print-fatal-signals=1
+
+can also be entered as::
+
+	log-buf-len=1M print_fatal_signals=1
+
+Double-quotes can be used to protect spaces in values, e.g.::
+
+	param="spaces in here"
+
+cpu lists:
+----------
+
+Some kernel parameters take a list of CPUs as a value, e.g.  isolcpus,
+nohz_full, irqaffinity, rcu_nocbs.  The format of this list is:
+
+	<cpu number>,...,<cpu number>
+
+or
+
+	<cpu number>-<cpu number>
+	(must be a positive range in ascending order)
+
+or a mixture
+
+<cpu number>,...,<cpu number>-<cpu number>
+
+Note that for the special case of a range one can split the range into equal
+sized groups and for each group use some amount from the beginning of that
+group:
+
+	<cpu number>-cpu number>:<used size>/<group size>
+
+For example one can add to the command line following parameter:
+
+	isolcpus=1,2,10-20,100-2000:2/25
+
+where the final item represents CPUs 100,101,125,126,150,151,...
+
+
+
+This document may not be entirely up to date and comprehensive. The command
+"modinfo -p ${modulename}" shows a current list of all parameters of a loadable
+module. Loadable modules, after being loaded into the running kernel, also
+reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
+parameters may be changed at runtime by the command
+``echo -n ${value} > /sys/module/${modulename}/parameters/${parm}``.
+
+The parameters listed below are only valid if certain kernel build options were
+enabled and if respective hardware is present. The text in square brackets at
+the beginning of each description states the restrictions within which a
+parameter is applicable::

-                          Kernel Parameters
-                          ~~~~~~~~~~~~~~~~~
-
-The following is a consolidated list of the kernel parameters as
-implemented by the __setup(), core_param() and module_param() macros
-and sorted into English Dictionary order (defined as ignoring all
-punctuation and sorting digits before letters in a case insensitive
-manner), and with descriptions where known.
-
-The kernel parses parameters from the kernel command line up to "--";
-if it doesn't recognize a parameter and it doesn't contain a '.', the
-parameter gets passed to init: parameters with '=' go into init's
-environment, others are passed as command line arguments to init.
-Everything after "--" is passed as an argument to init.
-
-Module parameters can be specified in two ways: via the kernel command
-line with a module name prefix, or via modprobe, e.g.:
-
-	(kernel command line) usbcore.blinkenlights=1
-	(modprobe command line) modprobe usbcore blinkenlights=1
-
-Parameters for modules which are built into the kernel need to be
-specified on the kernel command line.  modprobe looks through the
-kernel command line (/proc/cmdline) and collects module parameters
-when it loads a module, so the kernel command line can be used for
-loadable modules too.
-
-Hyphens (dashes) and underscores are equivalent in parameter names, so
-	log_buf_len=1M print-fatal-signals=1
-can also be entered as
-	log-buf-len=1M print_fatal_signals=1
-
-Double-quotes can be used to protect spaces in values, e.g.:
-	param="spaces in here"
-
-cpu lists:
-----------
-
-Some kernel parameters take a list of CPUs as a value, e.g.  isolcpus,
-nohz_full, irqaffinity, rcu_nocbs.  The format of this list is:
-
-	<cpu number>,...,<cpu number>
-
-or
-
-	<cpu number>-<cpu number>
-	(must be a positive range in ascending order)
-
-or a mixture
-
-<cpu number>,...,<cpu number>-<cpu number>
-
-Note that for the special case of a range one can split the range into equal
-sized groups and for each group use some amount from the beginning of that
-group:
-
-	<cpu number>-cpu number>:<used size>/<group size>
-
-For example one can add to the command line following parameter:
-
-	isolcpus=1,2,10-20,100-2000:2/25
-
-where the final item represents CPUs 100,101,125,126,150,151,...
-
-
-
-This document may not be entirely up to date and comprehensive. The command
-"modinfo -p ${modulename}" shows a current list of all parameters of a loadable
-module. Loadable modules, after being loaded into the running kernel, also
-reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
-parameters may be changed at runtime by the command
-"echo -n ${value} > /sys/module/${modulename}/parameters/${parm}".
-
-The parameters listed below are only valid if certain kernel build options were
-enabled and if respective hardware is present. The text in square brackets at
-the beginning of each description states the restrictions within which a
-parameter is applicable:

+The ``parport`` code provides parallel-port support under Linux.  This
+includes the ability to share one port between multiple device
+drivers.
+
+You can pass parameters to the ``parport`` code to override its automatic
+detection of your hardware.  This is particularly useful if you want
+to use IRQs, since in general these can't be autoprobed successfully.
+By default IRQs are not used even if they **can** be probed.  This is
+because there are a lot of people using the same IRQ for their
+parallel port and a sound card or network card.
+
+The ``parport`` code is split into two parts: generic (which deals with
+port-sharing) and architecture-dependent (which deals with actually
+using the port).
+
+
+Parport as modules
+==================
+
+If you load the `parport`` code as a module, say::
+
+	# insmod parport
+
+to load the generic ``parport`` code.  You then must load the
+architecture-dependent code with (for example)::
+
+	# insmod parport_pc io=0x3bc,0x378,0x278 irq=none,7,auto
+
+to tell the ``parport`` code that you want three PC-style ports, one at
+0x3bc with no IRQ, one at 0x378 using IRQ 7, and one at 0x278 with an
+auto-detected IRQ.  Currently, PC-style (``parport_pc``), Sun ``bpp``,
+Amiga, Atari, and MFC3 hardware is supported.
+
+PCI parallel I/O card support comes from ``parport_pc``.  Base I/O
+addresses should not be specified for supported PCI cards since they
+are automatically detected.
+
+
+modprobe
+--------
+
+If you use modprobe , you will find it useful to add lines as below to a
+configuration file in /etc/modprobe.d/ directory::
+
+	alias parport_lowlevel parport_pc
+	options parport_pc io=0x378,0x278 irq=7,auto
+
+modprobe will load ``parport_pc`` (with the options ``io=0x378,0x278 irq=7,auto``)
+whenever a parallel port device driver (such as ``lp``) is loaded.
+
+Note that these are example lines only!  You shouldn't in general need
+to specify any options to ``parport_pc`` in order to be able to use a
+parallel port.
+
+
+Parport probe [optional]
+------------------------
+
+In 2.2 kernels there was a module called ``parport_probe``, which was used
+for collecting IEEE 1284 device ID information.  This has now been
+enhanced and now lives with the IEEE 1284 support.  When a parallel
+port is detected, the devices that are connected to it are analysed,
+and information is logged like this::
+
+	parport0: Printer, BJC-210 (Canon)
+
+The probe information is available from files in ``/proc/sys/dev/parport/``.
+
+
+Parport linked into the kernel statically
+=========================================
+
+If you compile the ``parport`` code into the kernel, then you can use
+kernel boot parameters to get the same effect.  Add something like the
+following to your LILO command line::
+
+	parport=0x3bc parport=0x378,7 parport=0x278,auto,nofifo
+
+You can have many ``parport=...`` statements, one for each port you want
+to add.  Adding ``parport=0`` to the kernel command-line will disable
+parport support entirely.  Adding ``parport=auto`` to the kernel
+command-line will make ``parport`` use any IRQ lines or DMA channels that
+it auto-detects.
+
+
+Files in /proc
+==============
+
+If you have configured the ``/proc`` filesystem into your kernel, you will
+see a new directory entry: ``/proc/sys/dev/parport``.  In there will be a
+directory entry for each parallel port for which parport is
+configured.  In each of those directories are a collection of files
+describing that parallel port.
+
+The ``/proc/sys/dev/parport`` directory tree looks like::
+
+	parport
+	|-- default
+	|   |-- spintime
+	|   `-- timeslice
+	|-- parport0

+
+``spintime``		The number of microseconds to busy-loop while waiting

+			port is	registered, it picks up the default spintime.
+			When a new device is registered, it picks up the
+			default timeslice.
+=======================	=======================================================
+
+Device drivers
+==============
+
+Once the parport code is initialised, you can attach device drivers to
+specific ports.  Normally this happens automatically; if the lp driver
+is loaded it will create one lp device for each port found.  You can
+override this, though, by using parameters either when you load the lp
+driver::
+
+	# insmod lp parport=0,2
+
+or on the LILO command line::
+
+	lp=parport0 lp=parport2
+
+Both the above examples would inform lp that you want ``/dev/lp0`` to be
+the first parallel port, and /dev/lp1 to be the **third** parallel port,
+with no lp device associated with the second port (parport1).  Note
+that this is different to the way older kernels worked; there used to
+be a static association between the I/O port address and the device
+name, so ``/dev/lp0`` was always the port at 0x3bc.  This is no longer the
+case - if you only have one port, it will default to being ``/dev/lp0``,
+regardless of base address.
+
+Also:
+
+ * If you selected the IEEE 1284 support at compile time, you can say
+   ``lp=auto`` on the kernel command line, and lp will create devices
+   only for those ports that seem to have printers attached.
+
+ * If you give PLIP the ``timid`` parameter, either with ``plip=timid`` on
+   the command line, or with ``insmod plip timid=1`` when using modules,
+   it will avoid any ports that seem to be in use by other devices.
+
+ * IRQ autoprobing works only for a few port types at the moment.
+
+Reporting printer problems with parport
+=======================================
+
+If you are having problems printing, please go through these steps to
+try to narrow down where the problem area is.
+
+When reporting problems with parport, really you need to give all of
+the messages that ``parport_pc`` spits out when it initialises.  There are
+several code paths:
+
+- polling
+- interrupt-driven, protocol in software
+- interrupt-driven, protocol in hardware using PIO
+- interrupt-driven, protocol in hardware using DMA
+
+The kernel messages that ``parport_pc`` logs give an indication of which
+code path is being used. (They could be a lot better actually..)
+
+For normal printer protocol, having IEEE 1284 modes enabled or not
+should not make a difference.
+
+To turn off the 'protocol in hardware' code paths, disable
+``CONFIG_PARPORT_PC_FIFO``.  Note that when they are enabled they are not
+necessarily **used**; it depends on whether the hardware is available,
+enabled by the BIOS, and detected by the driver.
+
+So, to start with, disable ``CONFIG_PARPORT_PC_FIFO``, and load ``parport_pc``
+with ``irq=none``. See if printing works then.  It really should,
+because this is the simplest code path.
+
+If that works fine, try with ``io=0x378 irq=7`` (adjust for your
+hardware), to make it use interrupt-driven in-software protocol.
+
+If **that** works fine, then one of the hardware modes isn't working
+right.  Enable ``CONFIG_FIFO`` (no, it isn't a module option,
+and yes, it should be), set the port to ECP mode in the BIOS and note
+the DMA channel, and try with::
+
+    io=0x378 irq=7 dma=none (for PIO)
+    io=0x378 irq=7 dma=3 (for DMA)

 Ramoops is an oops/panic logger that writes its logs to RAM before the system

 Ramoops uses a predefined memory area to store the dump. The start and size
 and type of the memory area are set using three variables:
-  * "mem_address" for the start

 depends on atomic operations. At least on ARM, pgprot_noncached causes the
 memory to be mapped strongly ordered, and atomic operations on strongly ordered
 memory are implementation defined, and won't work on many ARMs such as omaps.

+Reliability, Availability and Serviceability
+============================================
+
+RAS concepts
+************
+
+Reliability, Availability and Serviceability (RAS) is a concept used on
+servers meant to measure their robusteness.
+
+Reliability
+  is the probability that a system will produce correct outputs.
+
+  * Generally measured as Mean Time Between Failures (MTBF)
+  * Enhanced by features that help to avoid, detect and repair hardware faults
+
+Availability
+  is the probability that a system is operational at a given time
+
+  * Generally measured as a percentage of downtime per a period of time
+  * Often uses mechanisms to detect and correct hardware faults in
+    runtime;
+
+Serviceability (or maintainability)
+  is the simplicity and speed with which a system can be repaired or
+  maintained
+
+  * Generally measured on Mean Time Between Repair (MTBR)
+
+Improving RAS
+-------------
+
+In order to reduce systems downtime, a system should be capable of detecting
+hardware errors, and, when possible correcting them in runtime. It should
+also provide mechanisms to detect hardware degradation, in order to warn
+the system administrator to take the action of replacing a component before
+it causes data loss or system downtime.
+
+Among the monitoring measures, the most usual ones include:
+
+* CPU – detect errors at instruction execution and at L1/L2/L3 caches;
+* Memory – add error correction logic (ECC) to detect and correct errors;
+* I/O – add CRC checksums for tranfered data;
+* Storage – RAID, journal file systems, checksums,
+  Self-Monitoring, Analysis and Reporting Technology (SMART).
+
+By monitoring the number of occurrences of error detections, it is possible
+to identify if the probability of hardware errors is increasing, and, on such
+case, do a preventive maintainance to replace a degrated component while
+those errors are correctable.
+
+Types of errors
+---------------
+
+Most mechanisms used on modern systems use use technologies like Hamming
+Codes that allow error correction when the number of errors on a bit packet
+is below a threshold. If the number of errors is above, those mechanisms
+can indicate with a high degree of confidence that an error happened, but
+they can't correct.
+
+Also, sometimes an error occur on a component that it is not used. For
+example, a part of the memory that it is not currently allocated.
+
+That defines some categories of errors:
+
+* **Correctable Error (CE)** - the error detection mechanism detected and
+  corrected the error. Such errors are usually not fatal, although some
+  Kernel mechanisms allow the system administrator to consider them as fatal.
+
+* **Uncorrected Error (UE)** - the amount of errors happened above the error
+  correction threshold, and the system was unable to auto-correct.
+
+* **Fatal Error** - when an UE error happens on a critical component of the
+  system (for example, a piece of the Kernel got corrupted by an UE), the
+  only reliable way to avoid data corruption is to hang or reboot the machine.
+
+* **Non-fatal Error** - when an UE error happens on an unused component,
+  like a CPU in power down state or an unused memory bank, the system may
+  still run, eventually replacing the affected hardware by a hot spare,
+  if available.
+
+  Also, when an error happens on an userspace process, it is also possible to
+  kill such process and let userspace restart it.
+
+The mechanism for handling non-fatal errors is usually complex and may
+require the help of some userspace application, in order to apply the
+policy desired by the system administrator.
+
+Identifying a bad hardware component
+------------------------------------
+
+Just detecting a hardware flaw is usually not enough, as the system needs
+to pinpoint to the minimal replaceable unit (MRU) that should be exchanged
+to make the hardware reliable again.
+
+So, it requires not only error logging facilities, but also mechanisms that
+will translate the error message to the silkscreen or component label for
+the MRU.
+
+Typically, it is very complex for memory, as modern CPUs interlace memory
+from different memory modules, in order to provide a better performance. The
+DMI BIOS usually have a list of memory module labels, with can be obtained
+using the ``dmidecode`` tool. For example, on a desktop machine, it shows::
+
+	Memory Device
+		Total Width: 64 bits
+		Data Width: 64 bits
+		Size: 16384 MB
+		Form Factor: SODIMM
+		Set: None
+		Locator: ChannelA-DIMM0
+		Bank Locator: BANK 0
+		Type: DDR4
+		Type Detail: Synchronous
+		Speed: 2133 MHz
+		Rank: 2
+		Configured Clock Speed: 2133 MHz
+
+On the above example, a DDR4 SO-DIMM memory module is located at the
+system's memory labeled as "BANK 0", as given by the *bank locator* field.
+Please notice that, on such system, the *total width* is equal to the
+*data witdh*. It means that such memory module doesn't have error
+detection/correction mechanisms.
+
+Unfortunately, not all systems use the same field to specify the memory
+bank. On this example, from an older server, ``dmidecode`` shows::
+
+	Memory Device
+		Array Handle: 0x1000
+		Error Information Handle: Not Provided
+		Total Width: 72 bits
+		Data Width: 64 bits
+		Size: 8192 MB
+		Form Factor: DIMM
+		Set: 1
+		Locator: DIMM_A1
+		Bank Locator: Not Specified
+		Type: DDR3
+		Type Detail: Synchronous Registered (Buffered)
+		Speed: 1600 MHz
+		Rank: 2
+		Configured Clock Speed: 1600 MHz
+
+There, the DDR3 RDIMM memory module is located at the system's memory labeled
+as "DIMM_A1", as given by the *locator* field. Please notice that this
+memory module has 64 bits of *data witdh* and 72 bits of *total width*. So,
+it has 8 extra bits to be used by error detection and correction mechanisms.
+Such kind of memory is called Error-correcting code memory (ECC memory).
+
+To make things even worse, it is not uncommon that systems with different
+labels on their system's board to use exactly the same BIOS, meaning that
+the labels provided by the BIOS won't match the real ones.
+
+ECC memory
+----------
+
+As mentioned on the previous section, ECC memory has extra bits to be
+used for error correction. So, on 64 bit systems, a memory module
+has 64 bits of *data width*, and 74 bits of *total width*. So, there are
+8 bits extra bits to be used for the error detection and correction
+mechanisms. Those extra bits are called *syndrome*\ [#f1]_\ [#f2]_.
+
+So, when the cpu requests the memory controller to write a word with
+*data width*, the memory controller calculates the *syndrome* in real time,
+using Hamming code, or some other error correction code, like SECDED+,
+producing a code with *total width* size. Such code is then written
+on the memory modules.
+
+At read, the *total width* bits code is converted back, using the same
+ECC code used on write, producing a word with *data width* and a *syndrome*.
+The word with *data width* is sent to the CPU, even when errors happen.
+
+The memory controller also looks at the *syndrome* in order to check if
+there was an error, and if the ECC code was able to fix such error.
+If the error was corrected, a Corrected Error (CE) happened. If not, an
+Uncorrected Error (UE) happened.
+
+The information about the CE/UE errors is stored on some special registers
+at the memory controller and can be accessed by reading such registers,
+either by BIOS, by some special CPUs or by Linux EDAC driver. On x86 64
+bit CPUs, such errors can also be retrieved via the Machine Check
+Architecture (MCA)\ [#f3]_.
+
+.. [#f1] Please notice that several memory controllers allow operation on a
+  mode called "Lock-Step", where it groups two memory modules together,
+  doing 128-bit reads/writes. That gives 16 bits for error correction, with
+  significatively improves the error correction mechanism, at the expense
+  that, when an error happens, there's no way to know what memory module is
+  to blame. So, it has to blame both memory modules.
+
+.. [#f2] Some memory controllers also allow using memory in mirror mode.
+  On such mode, the same data is written to two memory modules. At read,
+  the system checks both memory modules, in order to check if both provide
+  identical data. On such configuration, when an error happens, there's no
+  way to know what memory module is to blame. So, it has to blame both
+  memory modules (or 4 memory modules, if the system is also on Lock-step
+  mode).
+
+.. [#f3] For more details about the Machine Check Architecture (MCA),
+  please read Documentation/x86/x86_64/machinecheck at the Kernel tree.

+   That site is mostly archaic now and can be used only for historical
+   purposes.
+
+   When the subsystem was pushed upstream for the first time, on
+   Kernel 2.6.16, for the first time, it was renamed to ``EDAC``.
+
+Purpose
+-------
+
+The ``edac`` kernel module's goal is to detect and report hardware errors
+that occur within the computer system running under linux.
+
+Memory
+------
+
+Memory Correctable Errors (CE) and Uncorrectable Errors (UE) are the
+primary errors being harvested. These types of errors are harvested by
+the ``edac_mc`` device.
+
+Detecting CE events, then harvesting those events and reporting them,
+**can** but must not necessarily be a predictor of future UE events. With
+CE events only, the system can and will continue to operate as no data
+has been damaged yet.
+
+However, preventive maintenance and proactive part replacement of memory
+modules exhibiting CEs can reduce the likelihood of the dreaded UE events
+and system panics.
+
+Other hardware elements
+-----------------------
+
+A new feature for EDAC, the ``edac_device`` class of device, was added in
+the 2.6.23 version of the kernel.
+
+This new device type allows for non-memory type of ECC hardware detectors
+to have their states harvested and presented to userspace via the sysfs
+interface.
+
+Some architectures have ECC detectors for L1, L2 and L3 caches,
+along with DMA engines, fabric switches, main data path switches,
+interconnections, and various other hardware data paths. If the hardware
+reports it, then a edac_device device probably can be constructed to
+harvest and present that to userspace.
+
+
+PCI bus scanning
+----------------
+
+In addition, PCI devices are scanned for PCI Bus Parity and SERR Errors
+in order to determine if errors are occurring during data transfers.
+
+The presence of PCI Parity errors must be examined with a grain of salt.
+There are several add-in adapters that do **not** follow the PCI specification
+with regards to Parity generation and reporting. The specification says
+the vendor should tie the parity status bits to 0 if they do not intend
+to generate parity.  Some vendors do not do this, and thus the parity bit
+can "float" giving false positives.
+
+There is a PCI device attribute located in sysfs that is checked by
+the EDAC PCI scanning code. If that attribute is set, PCI parity/error
+scanning is skipped for that device. The attribute is::
+
+	broken_parity_status
+
+and is located in ``/sys/devices/pci<XXX>/0000:XX:YY.Z`` directories for
+PCI devices.
+
+
+Versioning
+----------
+
+EDAC is composed of a "core" module (``edac_core.ko``) and several Memory
+Controller (MC) driver modules. On a given system, the CORE is loaded
+and one MC driver will be loaded. Both the CORE and the MC driver (or
+``edac_device`` driver) have individual versions that reflect current
+release level of their respective modules.
+
+Thus, to "report" on what version a system is running, one must report
+both the CORE's and the MC driver's versions.
+
+
+Loading
+-------
+
+If ``edac`` was statically linked with the kernel then no loading
+is necessary. If ``edac`` was built as modules then simply modprobe
+the ``edac`` pieces that you need. You should be able to modprobe
+hardware-specific modules and have the dependencies load the necessary
+core modules.
+
+Example::
+
+	$ modprobe amd76x_edac
+
+loads both the ``amd76x_edac.ko`` memory controller module and the
+``edac_mc.ko`` core module.
+
+
+Sysfs interface
+---------------
+
+EDAC presents a ``sysfs`` interface for control and reporting purposes. It
+lives in the /sys/devices/system/edac directory.
+
+Within this directory there currently reside 2 components:
+
+	======= ==============================
+	mc	memory controller(s) system
+	pci	PCI control and status system
+	======= ==============================
+
+
+
+Memory Controller (mc) Model
+----------------------------
+
+Each ``mc`` device controls a set of memory modules [#f4]_. These modules
+are laid out in a Chip-Select Row (``csrowX``) and Channel table (``chX``).
+There can be multiple csrows and multiple channels.
+
+.. [#f4] Nowadays, the term DIMM (Dual In-line Memory Module) is widely
+  used to refer to a memory module, although there are other memory
+  packaging alternatives, like SO-DIMM, SIMM, etc. Along this document,
+  and inside the EDAC system, the term "dimm" is used for all memory
+  modules, even when they use a different kind of packaging.
+
+Memory controllers allow for several csrows, with 8 csrows being a
+typical value. Yet, the actual number of csrows depends on the layout of
+a given motherboard, memory controller and memory module characteristics.
+
+Dual channels allow for dual data length (e. g. 128 bits, on 64 bit systems)
+data transfers to/from the CPU from/to memory. Some newer chipsets allow
+for more than 2 channels, like Fully Buffered DIMMs (FB-DIMMs) memory
+controllers. The following example will assume 2 channels:
+
+	+------------+-----------------------+
+	| Chip       |       Channels        |
+	| Select     +-----------+-----------+
+	| rows       |  ``ch0``  |  ``ch1``  |
+	+============+===========+===========+
+	| ``csrow0`` |  DIMM_A0  |  DIMM_B0  |
+	+------------+           |           |
+	| ``csrow1`` |           |           |
+	+------------+-----------+-----------+
+	| ``csrow2`` |  DIMM_A1  | DIMM_B1   |
+	+------------+           |           |
+	| ``csrow3`` |           |           |
+	+------------+-----------+-----------+
+
+In the above example, there are 4 physical slots on the motherboard
+for memory DIMMs:
+
+	+---------+---------+
+	| DIMM_A0 | DIMM_B0 |
+	+---------+---------+
+	| DIMM_A1 | DIMM_B1 |
+	+---------+---------+
+
+Labels for these slots are usually silk-screened on the motherboard.
+Slots labeled ``A`` are channel 0 in this example. Slots labeled ``B`` are
+channel 1. Notice that there are two csrows possible on a physical DIMM.
+These csrows are allocated their csrow assignment based on the slot into
+which the memory DIMM is placed. Thus, when 1 DIMM is placed in each
+Channel, the csrows cross both DIMMs.
+
+Memory DIMMs come single or dual "ranked". A rank is a populated csrow.
+Thus, 2 single ranked DIMMs, placed in slots DIMM_A0 and DIMM_B0 above
+will have just one csrow (csrow0). csrow1 will be empty. On the other
+hand, when 2 dual ranked DIMMs are similarly placed, then both csrow0
+and csrow1 will be populated. The pattern repeats itself for csrow2 and
+csrow3.
+
+The representation of the above is reflected in the directory
+tree in EDAC's sysfs interface. Starting in directory
+``/sys/devices/system/edac/mc``, each memory controller will be
+represented by its own ``mcX`` directory, where ``X`` is the
+index of the MC::
+
+	..../edac/mc/
+		   |
+		   |->mc0
+		   |->mc1
+		   |->mc2
+		   ....
+
+Under each ``mcX`` directory each ``csrowX`` is again represented by a
+``csrowX``, where ``X`` is the csrow index::
+
+	.../mc/mc0/
+		|
+		|->csrow0
+		|->csrow2
+		|->csrow3
+		....
+
+Notice that there is no csrow1, which indicates that csrow0 is composed
+of a single ranked DIMMs. This should also apply in both Channels, in
+order to have dual-channel mode be operational. Since both csrow2 and
+csrow3 are populated, this indicates a dual ranked set of DIMMs for
+channels 0 and 1.
+
+Within each of the ``mcX`` and ``csrowX`` directories are several EDAC
+control and attribute files.
+
+``mcX`` directories
+-------------------
+
+In ``mcX`` directories are EDAC control and attribute files for
+this ``X`` instance of the memory controllers.
+
+For a description of the sysfs API, please see:
+
+	Documentation/ABI/testing/sysfs-devices-edac
+
+
+``dimmX`` or ``rankX`` directories
+----------------------------------
+
+The recommended way to use the EDAC subsystem is to look at the information
+provided by the ``dimmX`` or ``rankX`` directories [#f5]_.
+
+A typical EDAC system has the following structure under
+``/sys/devices/system/edac/``\ [#f6]_::
+
+	/sys/devices/system/edac/
+	├── mc
+	│   ├── mc0
+	│   │   ├── ce_count
+	│   │   ├── ce_noinfo_count
+	│   │   ├── dimm0

+	│   └── uevent
+	└── uevent
+
+In the ``dimmX`` directories are EDAC control and attribute files for
+this ``X`` memory module:
+
+- ``size`` - Total memory managed by this csrow attribute file
+
+	This attribute file displays, in count of megabytes, the memory
+	that this csrow contains.
+
+- ``dimm_dev_type``  - Device type attribute file
+
+	This attribute file will display what type of DRAM device is
+	being utilized on this DIMM.
+	Examples:
+
+		- x1
+		- x2
+		- x4
+		- x8
+
+- ``dimm_edac_mode`` - EDAC Mode of operation attribute file
+
+	This attribute file will display what type of Error detection
+	and correction is being utilized.
+
+- ``dimm_label`` - memory module label control file
+
+	This control file allows this DIMM to have a label assigned
+	to it. With this label in the module, when errors occur
+	the output can provide the DIMM label in the system log.
+	This becomes vital for panic events to isolate the
+	cause of the UE event.
+
+	DIMM Labels must be assigned after booting, with information
+	that correctly identifies the physical slot with its
+	silk screen label. This information is currently very
+	motherboard specific and determination of this information
+	must occur in userland at this time.
+
+- ``dimm_location`` - location of the memory module
+
+	The location can have up to 3 levels, and describe how the
+	memory controller identifies the location of a memory module.
+	Depending on the type of memory and memory controller, it
+	can be:
+
+		- *csrow* and *channel* - used when the memory controller
+		  doesn't identify a single DIMM - e. g. in ``rankX`` dir;
+		- *branch*, *channel*, *slot* - typically used on FB-DIMM memory
+		  controllers;
+		- *channel*, *slot* - used on Nehalem and newer Intel drivers.
+
+- ``dimm_mem_type`` - Memory Type attribute file
+
+	This attribute file will display what type of memory is currently
+	on this csrow. Normally, either buffered or unbuffered memory.
+	Examples:
+
+		- Registered-DDR
+		- Unbuffered-DDR
+
+.. [#f5] On some systems, the memory controller doesn't have any logic
+  to identify the memory module. On such systems, the directory is called ``rankX`` and works on a similar way as the ``csrowX`` directories.
+  On modern Intel memory controllers, the memory controller identifies the
+  memory modules directly. On such systems, the directory is called ``dimmX``.
+
+.. [#f6] There are also some ``power`` directories and ``subsystem``
+  symlinks inside the sysfs mapping that are automatically created by
+  the sysfs subsystem. Currently, they serve no purpose.
+
+``csrowX`` directories
+----------------------
+
+When CONFIG_EDAC_LEGACY_SYSFS is enabled, sysfs will contain the ``csrowX``
+directories. As this API doesn't work properly for Rambus, FB-DIMMs and
+modern Intel Memory Controllers, this is being deprecated in favor of
+``dimmX`` directories.
+
+In the ``csrowX`` directories are EDAC control and attribute files for
+this ``X`` instance of csrow:
+
+
+- ``ue_count`` - Total Uncorrectable Errors count attribute file
+
+	This attribute file displays the total count of uncorrectable
+	errors that have occurred on this csrow. If panic_on_ue is set
+	this counter will not have a chance to increment, since EDAC
+	will panic the system.
+
+
+- ``ce_count`` - Total Correctable Errors count attribute file
+
+	This attribute file displays the total count of correctable
+	errors that have occurred on this csrow. This count is very
+	important to examine. CEs provide early indications that a
+	DIMM is beginning to fail. This count field should be
+	monitored for non-zero values and report such information
+	to the system administrator.
+
+
+- ``size_mb`` - Total memory managed by this csrow attribute file
+
+	This attribute file displays, in count of megabytes, the memory
+	that this csrow contains.
+
+
+- ``mem_type`` - Memory Type attribute file
+
+	This attribute file will display what type of memory is currently
+	on this csrow. Normally, either buffered or unbuffered memory.
+	Examples:
+
+		- Registered-DDR
+		- Unbuffered-DDR
+
+
+- ``edac_mode`` - EDAC Mode of operation attribute file
+
+	This attribute file will display what type of Error detection
+	and correction is being utilized.
+
+
+- ``dev_type`` - Device type attribute file
+
+	This attribute file will display what type of DRAM device is
+	being utilized on this DIMM.
+	Examples:
+
+		- x1
+		- x2
+		- x4
+		- x8
+
+
+- ``ch0_ce_count`` - Channel 0 CE Count attribute file
+
+	This attribute file will display the count of CEs on this
+	DIMM located in channel 0.
+
+
+- ``ch0_ue_count`` - Channel 0 UE Count attribute file
+
+	This attribute file will display the count of UEs on this
+	DIMM located in channel 0.
+
+
+- ``ch0_dimm_label`` - Channel 0 DIMM Label control file
+
+
+	This control file allows this DIMM to have a label assigned
+	to it. With this label in the module, when errors occur
+	the output can provide the DIMM label in the system log.
+	This becomes vital for panic events to isolate the
+	cause of the UE event.
+
+	DIMM Labels must be assigned after booting, with information
+	that correctly identifies the physical slot with its
+	silk screen label. This information is currently very
+	motherboard specific and determination of this information
+	must occur in userland at this time.
+
+
+- ``ch1_ce_count`` - Channel 1 CE Count attribute file
+
+
+	This attribute file will display the count of CEs on this
+	DIMM located in channel 1.
+
+
+- ``ch1_ue_count`` - Channel 1 UE Count attribute file
+
+
+	This attribute file will display the count of UEs on this
+	DIMM located in channel 0.
+
+
+- ``ch1_dimm_label`` - Channel 1 DIMM Label control file
+
+	This control file allows this DIMM to have a label assigned
+	to it. With this label in the module, when errors occur
+	the output can provide the DIMM label in the system log.
+	This becomes vital for panic events to isolate the

+
+
+System Logging
+--------------
+
+If logging for UEs and CEs is enabled, then system logs will contain
+information indicating that errors have been detected::
+
+  EDAC MC0: CE page 0x283, offset 0xce0, grain 8, syndrome 0x6ec3, row 0, channel 1 "DIMM_B1": amd76x_edac
+  EDAC MC0: CE page 0x1e5, offset 0xfb0, grain 8, syndrome 0xb741, row 0, channel 1 "DIMM_B1": amd76x_edac
+
+
+The structure of the message is:
+

+	+---------------------------------------+-------------+
+
+Both UEs and CEs with no info will lack all but memory controller, error
+type, a notice of "no info" and then an optional, driver-specific error
+message.
+
+
+PCI Bus Parity Detection
+------------------------
+
+On Header Type 00 devices, the primary status is looked at for any
+parity error regardless of whether parity is enabled on the device or
+not. (The spec indicates parity is generated in some cases). On Header
+Type 01 bridges, the secondary status register is also looked at to see
+if parity occurred on the bus on the other side of the bridge.
+
+
+Sysfs configuration
+-------------------
+
+Under ``/sys/devices/system/edac/pci`` are control and attribute files as
+follows:
+
+
+- ``check_pci_parity`` - Enable/Disable PCI Parity checking control file
+
+	This control file enables or disables the PCI Bus Parity scanning
+	operation. Writing a 1 to this file enables the scanning. Writing
+	a 0 to this file disables the scanning.
+
+	Enable::
+
+		echo "1" >/sys/devices/system/edac/pci/check_pci_parity
+
+	Disable::
+
+		echo "0" >/sys/devices/system/edac/pci/check_pci_parity
+
+
+- ``pci_parity_count`` - Parity Count
+
+	This attribute file will display the number of parity errors that
+	have been detected.
+
+
+Module parameters
+-----------------
+
+- ``edac_mc_panic_on_ue`` - Panic on UE control file
+
+	An uncorrectable error will cause a machine panic.  This is usually
+	desirable.  It is a bad idea to continue when an uncorrectable error
+	occurs - it is indeterminate what was uncorrected and the operating
+	system context might be so mangled that continuing will lead to further
+	corruption. If the kernel has MCE configured, then EDAC will never
+	notice the UE.
+
+	LOAD TIME::
+
+		module/kernel parameter: edac_mc_panic_on_ue=[0|1]
+
+	RUN TIME::
+
+		echo "1" > /sys/module/edac_core/parameters/edac_mc_panic_on_ue
+
+
+- ``edac_mc_log_ue`` - Log UE control file
+
+
+	Generate kernel messages describing uncorrectable errors.  These errors
+	are reported through the system message log system.  UE statistics
+	will be accumulated even when UE logging is disabled.
+
+	LOAD TIME::
+
+		module/kernel parameter: edac_mc_log_ue=[0|1]
+
+	RUN TIME::
+
+		echo "1" > /sys/module/edac_core/parameters/edac_mc_log_ue
+
+
+- ``edac_mc_log_ce`` - Log CE control file
+
+
+	Generate kernel messages describing correctable errors.  These
+	errors are reported through the system message log system.
+	CE statistics will be accumulated even when CE logging is disabled.
+
+	LOAD TIME::
+
+		module/kernel parameter: edac_mc_log_ce=[0|1]
+
+	RUN TIME::
+
+		echo "1" > /sys/module/edac_core/parameters/edac_mc_log_ce
+
+
+- ``edac_mc_poll_msec`` - Polling period control file
+
+
+	The time period, in milliseconds, for polling for error information.
+	Too small a value wastes resources.  Too large a value might delay
+	necessary handling of errors and might loose valuable information for
+	locating the error.  1000 milliseconds (once each second) is the current
+	default. Systems which require all the bandwidth they can get, may
+	increase this.
+
+	LOAD TIME::
+
+		module/kernel parameter: edac_mc_poll_msec=[0|1]
+
+	RUN TIME::
+
+		echo "1000" > /sys/module/edac_core/parameters/edac_mc_poll_msec
+
+
+- ``panic_on_pci_parity`` - Panic on PCI PARITY Error
+
+
+	This control file enables or disables panicking when a parity
+	error has been detected.
+
+
+	module/kernel parameter::
+
+			edac_panic_on_pci_pe=[0|1]
+
+	Enable::

+
+
+EDAC device type
+----------------
+
+In the header file, edac_pci.h, there is a series of edac_device structures
+and APIs for the EDAC_DEVICE.
+
+User space access to an edac_device is through the sysfs interface.
+
+At the location ``/sys/devices/system/edac`` (sysfs) new edac_device devices
+will appear.
+
+There is a three level tree beneath the above ``edac`` directory. For example,
+the ``test_device_edac`` device (found at the http://bluesmoke.sourceforget.net
+website) installs itself as::
+
+	/sys/devices/system/edac/test-instance
+
+in this directory are various controls, a symlink and one or more ``instance``
+directories.
+
+The standard default controls are:
+
+	==============	=======================================================
+	log_ce		boolean to log CE events
+	log_ue		boolean to log UE events
+	panic_on_ue	boolean to ``panic`` the system if an UE is encountered
+			(default off, can be set true via startup script)
+	poll_msec	time period between POLL cycles for events
+	==============	=======================================================
+
+The test_device_edac device adds at least one of its own custom control:
+
+	==============	==================================================
+	test_bits	which in the current test driver does nothing but
+			show how it is installed. A ported driver can
+			add one or more such controls and/or attributes
+			for specific uses.
+			One out-of-tree driver uses controls here to allow
+			for ERROR INJECTION operations to hardware
+			injection registers
+	==============	==================================================
+
+The symlink points to the 'struct dev' that is registered for this edac_device.
+
+Instances
+---------
+
+One or more instance directories are present. For the ``test_device_edac``
+case:
+
+	+----------------+
+	| test-instance0 |
+	+----------------+
+
+
+In this directory there are two default counter attributes, which are totals of
+counter in deeper subdirectories.
+
+	==============	====================================
+	ce_count	total of CE events of subdirectories
+	ue_count	total of UE events of subdirectories
+	==============	====================================
+
+Blocks
+------
+
+At the lowest directory level is the ``block`` directory. There can be 0, 1
+or more blocks specified in each instance:
+
+	+-------------+
+	| test-block0 |
+	+-------------+
+
+In this directory the default attributes are:
+

+
+Usage of EDAC APIs on Nehalem and newer Intel CPUs
+--------------------------------------------------
+
+On older Intel architectures, the memory controller was part of the North
+Bridge chipset. Nehalem, Sandy Bridge, Ivy Bridge, Haswell, Sky Lake and
+newer Intel architectures integrated an enhanced version of the memory
+controller (MC) inside the CPUs.
+
+This chapter will cover the differences of the enhanced memory controllers
+found on newer Intel CPUs, such as ``i7core_edac``, ``sb_edac`` and
+``sbx_edac`` drivers.
+
+.. note::
+
+   The Xeon E7 processor families use a separate chip for the memory
+   controller, called Intel Scalable Memory Buffer. This section doesn't
+   apply for such families.
+
+1) There is one Memory Controller per Quick Patch Interconnect
+   (QPI). At the driver, the term "socket" means one QPI. This is
+   associated with a physical CPU socket.
+
+   Each MC have 3 physical read channels, 3 physical write channels and
+   3 logic channels. The driver currently sees it as just 3 channels.
+   Each channel can have up to 3 DIMMs.
+
+   The minimum known unity is DIMMs. There are no information about csrows.
+   As EDAC API maps the minimum unity is csrows, the driver sequentially
+   maps channel/DIMM into different csrows.
+
+   For example, supposing the following layout::
+
+	Ch0 phy rd0, wr0 (0x063f4031): 2 ranks, UDIMMs
+	  dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
+	  dimm 1 1024 Mb offset: 4, bank: 8, rank: 1, row: 0x4000, col: 0x400
+        Ch1 phy rd1, wr1 (0x063f4031): 2 ranks, UDIMMs
+	  dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
+	Ch2 phy rd3, wr3 (0x063f4031): 2 ranks, UDIMMs
+	  dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
+
+   The driver will map it as::
+
+	csrow0: channel 0, dimm0
+	csrow1: channel 0, dimm1
+	csrow2: channel 1, dimm0
+	csrow3: channel 2, dimm0
+
+   exports one DIMM per csrow.
+
+   Each QPI is exported as a different memory controller.
+
+2) The MC has the ability to inject errors to test drivers. The drivers
+   implement this functionality via some error injection nodes:
+
+   For injecting a memory error, there are some sysfs nodes, under
+   ``/sys/devices/system/edac/mc/mc?/``:
+
+   - ``inject_addrmatch/*``:
+      Controls the error injection mask register. It is possible to specify
+      several characteristics of the address to match an error code::
+
+         dimm = the affected dimm. Numbers are relative to a channel;
+         rank = the memory rank;
+         channel = the channel that will generate an error;
+         bank = the affected bank;
+         page = the page address;
+         column (or col) = the address column.
+
+      each of the above values can be set to "any" to match any valid value.
+
+      At driver init, all values are set to any.
+
+      For example, to generate an error at rank 1 of dimm 2, for any channel,
+      any bank, any page, any column::
+
+		echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
+		echo 1 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
+
+	To return to the default behaviour of matching any, you can do::
+
+		echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
+		echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
+
+   - ``inject_eccmask``:
+          specifies what bits will have troubles,
+
+   - ``inject_section``:
+       specifies what ECC cache section will get the error::
+
+		3 for both
+		2 for the highest
+		1 for the lowest
+
+   - ``inject_type``:
+       specifies the type of error, being a combination of the following bits::
+
+		bit 0 - repeat
+		bit 1 - ecc
+		bit 2 - parity
+
+   - ``inject_enable``:
+       starts the error generation when something different than 0 is written.
+
+   All inject vars can be read. root permission is needed for write.
+
+   Datasheet states that the error will only be generated after a write on an
+   address that matches inject_addrmatch. It seems, however, that reading will
+   also produce an error.
+
+   For example, the following code will generate an error for any write access
+   at socket 0, on any DIMM/address on channel 2::
+
+	echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/channel
+	echo 2 >/sys/devices/system/edac/mc/mc0/inject_type
+	echo 64 >/sys/devices/system/edac/mc/mc0/inject_eccmask
+	echo 3 >/sys/devices/system/edac/mc/mc0/inject_section
+	echo 1 >/sys/devices/system/edac/mc/mc0/inject_enable
+	dd if=/dev/mem of=/dev/null seek=16k bs=4k count=1 >& /dev/null
+
+   For socket 1, it is needed to replace "mc0" by "mc1" at the above
+   commands.
+
+   The generated error message will look like::
+
+	EDAC MC0: UE row 0, channel-a= 0 channel-b= 0 labels "-": NON_FATAL (addr = 0x0075b980, socket=0, Dimm=0, Channel=2, syndrome=0x00000040, count=1, Err=8c0000400001009f:4000080482 (read error: read ECC error))
+
+3) Corrected Error memory register counters
+
+   Those newer MCs have some registers to count memory errors. The driver
+   uses those registers to report Corrected Errors on devices with Registered
+   DIMMs.
+
+   However, those counters don't work with Unregistered DIMM. As the chipset
+   offers some counters that also work with UDIMMs (but with a worse level of
+   granularity than the default ones), the driver exposes those registers for
+   UDIMM memories.
+
+   They can be read by looking at the contents of ``all_channel_counts/``::
+
+     $ for i in /sys/devices/system/edac/mc/mc0/all_channel_counts/*; do echo $i; cat $i; done
+	/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm0
+	0
+	/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm1
+	0
+	/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm2
+	0
+
+   What happens here is that errors on different csrows, but at the same
+   dimm number will increment the same counter.
+   So, in this memory mapping::
+
+	csrow0: channel 0, dimm0
+	csrow1: channel 0, dimm1
+	csrow2: channel 1, dimm0
+	csrow3: channel 2, dimm0
+
+   The hardware will increment udimm0 for an error at the first dimm at either
+   csrow0, csrow2  or csrow3;
+
+   The hardware will increment udimm1 for an error at the second dimm at either
+   csrow0, csrow2  or csrow3;
+
+   The hardware will increment udimm2 for an error at the third dimm at either
+   csrow0, csrow2  or csrow3;
+
+4) Standard error counters
+
+   The standard error counters are generated when an mcelog error is received
+   by the driver. Since, with UDIMM, this is counted by software, it is
+   possible that some errors could be lost. With RDIMM's, they display the
+   contents of the registers

+Rules on how to access information in sysfs
+===========================================
+
+The kernel-exported sysfs exports internal kernel implementation details
+and depends on internal kernel structures and layout. It is agreed upon
+by the kernel developers that the Linux kernel does not provide a stable
+internal API. Therefore, there are aspects of the sysfs interface that
+may not be stable across kernel releases.
+
+To minimize the risk of breaking users of sysfs, which are in most cases
+low-level userspace applications, with a new kernel release, the users
+of sysfs must follow some rules to use an as-abstract-as-possible way to
+access this filesystem. The current udev and HAL programs already
+implement this and users are encouraged to plug, if possible, into the
+abstractions these programs provide instead of accessing sysfs directly.
+
+But if you really do want or need to access sysfs directly, please follow
+the following rules and then your programs should work with future
+versions of the sysfs interface.
+
+- Do not use libsysfs
+    It makes assumptions about sysfs which are not true. Its API does not
+    offer any abstraction, it exposes all the kernel driver-core
+    implementation details in its own API. Therefore it is not better than
+    reading directories and opening the files yourself.
+    Also, it is not actively maintained, in the sense of reflecting the
+    current kernel development. The goal of providing a stable interface
+    to sysfs has failed; it causes more problems than it solves. It
+    violates many of the rules in this document.
+
+- sysfs is always at ``/sys``
+    Parsing ``/proc/mounts`` is a waste of time. Other mount points are a
+    system configuration bug you should not try to solve. For test cases,
+    possibly support a ``SYSFS_PATH`` environment variable to overwrite the
+    application's behavior, but never try to search for sysfs. Never try
+    to mount it, if you are not an early boot script.
+
+- devices are only "devices"
+    There is no such thing like class-, bus-, physical devices,
+    interfaces, and such that you can rely on in userspace. Everything is
+    just simply a "device". Class-, bus-, physical, ... types are just
+    kernel implementation details which should not be expected by
+    applications that look for devices in sysfs.
+
+    The properties of a device are:
+
+    - devpath (``/devices/pci0000:00/0000:00:1d.1/usb2/2-2/2-2:1.0``)
+
+      - identical to the DEVPATH value in the event sent from the kernel
+        at device creation and removal
+      - the unique key to the device at that point in time
+      - the kernel's path to the device directory without the leading
+        ``/sys``, and always starting with a slash
+      - all elements of a devpath must be real directories. Symlinks
+        pointing to /sys/devices must always be resolved to their real
+        target and the target path must be used to access the device.
+        That way the devpath to the device matches the devpath of the
+        kernel used at event time.
+      - using or exposing symlink values as elements in a devpath string
+        is a bug in the application
+
+    - kernel name (``sda``, ``tty``, ``0000:00:1f.2``, ...)
+
+      - a directory name, identical to the last element of the devpath
+      - applications need to handle spaces and characters like ``!`` in
+        the name
+
+    - subsystem (``block``, ``tty``, ``pci``, ...)
+
+      - simple string, never a path or a link
+      - retrieved by reading the "subsystem"-link and using only the
+        last element of the target path
+
+    - driver (``tg3``, ``ata_piix``, ``uhci_hcd``)
+
+      - a simple string, which may contain spaces, never a path or a
+        link
+      - it is retrieved by reading the "driver"-link and using only the
+        last element of the target path
+      - devices which do not have "driver"-link just do not have a
+        driver; copying the driver value in a child device context is a
+        bug in the application
+
+    - attributes
+
+      - the files in the device directory or files below subdirectories
+        of the same device directory
+      - accessing attributes reached by a symlink pointing to another device,
+        like the "device"-link, is a bug in the application
+
+    Everything else is just a kernel driver-core implementation detail
+    that should not be assumed to be stable across kernel releases.
+
+- Properties of parent devices never belong into a child device.
+    Always look at the parent devices themselves for determining device
+    context properties. If the device ``eth0`` or ``sda`` does not have a
+    "driver"-link, then this device does not have a driver. Its value is empty.
+    Never copy any property of the parent-device into a child-device. Parent
+    device properties may change dynamically without any notice to the
+    child device.
+
+- Hierarchy in a single device tree
+    There is only one valid place in sysfs where hierarchy can be examined
+    and this is below: ``/sys/devices.``
+    It is planned that all device directories will end up in the tree
+    below this directory.
+
+- Classification by subsystem
+    There are currently three places for classification of devices:
+    ``/sys/block,`` ``/sys/class`` and ``/sys/bus.`` It is planned that these will
+    not contain any device directories themselves, but only flat lists of
+    symlinks pointing to the unified ``/sys/devices`` tree.
+    All three places have completely different rules on how to access
+    device information. It is planned to merge all three
+    classification directories into one place at ``/sys/subsystem``,
+    following the layout of the bus directories. All buses and
+    classes, including the converted block subsystem, will show up
+    there.
+    The devices belonging to a subsystem will create a symlink in the
+    "devices" directory at ``/sys/subsystem/<name>/devices``,
+
+    If ``/sys/subsystem`` exists, ``/sys/bus``, ``/sys/class`` and ``/sys/block``
+    can be ignored. If it does not exist, you always have to scan all three
+    places, as the kernel is free to move a subsystem from one place to
+    the other, as long as the devices are still reachable by the same
+    subsystem name.
+
+    Assuming ``/sys/class/<subsystem>`` and ``/sys/bus/<subsystem>``, or
+    ``/sys/block`` and ``/sys/class/block`` are not interchangeable is a bug in
+    the application.
+
+- Block
+    The converted block subsystem at ``/sys/class/block`` or
+    ``/sys/subsystem/block`` will contain the links for disks and partitions
+    at the same level, never in a hierarchy. Assuming the block subsystem to
+    contain only disks and not partition devices in the same flat list is
+    a bug in the application.
+
+- "device"-link and <subsystem>:<kernel name>-links
+    Never depend on the "device"-link. The "device"-link is a workaround
+    for the old layout, where class devices are not created in
+    ``/sys/devices/`` like the bus devices. If the link-resolving of a
+    device directory does not end in ``/sys/devices/``, you can use the
+    "device"-link to find the parent devices in ``/sys/devices/``, That is the
+    single valid use of the "device"-link; it must never appear in any
+    path as an element. Assuming the existence of the "device"-link for
+    a device in ``/sys/devices/`` is a bug in the application.
+    Accessing ``/sys/class/net/eth0/device`` is a bug in the application.
+
+    Never depend on the class-specific links back to the ``/sys/class``
+    directory.  These links are also a workaround for the design mistake
+    that class devices are not created in ``/sys/devices.`` If a device
+    directory does not contain directories for child devices, these links
+    may be used to find the child devices in ``/sys/class.`` That is the single
+    valid use of these links; they must never appear in any path as an
+    element. Assuming the existence of these links for devices which are
+    real child device directories in the ``/sys/devices`` tree is a bug in
+    the application.
+
+    It is planned to remove all these links when all class device
+    directories live in ``/sys/devices.``
+
+- Position of devices along device chain can change.
+    Never depend on a specific parent device position in the devpath,
+    or the chain of parent devices. The kernel is free to insert devices into
+    the chain. You must always request the parent device you are looking for
+    by its subsystem value. You need to walk up the chain until you find
+    the device that matches the expected subsystem. Depending on a specific
+    position of a parent device or exposing relative paths using ``../`` to
+    access the chain of parents is a bug in the application.
+
+- When reading and writing sysfs device attribute files, avoid dependency
+    on specific error codes wherever possible. This minimizes coupling to
+    the error handling implementation within the kernel.
+
+    In general, failures to read or write sysfs device attributes shall
+    propagate errors wherever possible. Common errors include, but are not
+    limited to:
+
+	``-EIO``: The read or store operation is not supported, typically
+	returned by the sysfs system itself if the read or store pointer
+	is ``NULL``.
+
+	``-ENXIO``: The read or store operation failed
+
+    Error codes will not be changed without good reason, and should a change
+    to error codes result in user-space breakage, it will be fixed, or the
+    the offending change will be reverted.
+
+    Userspace applications can, however, expect the format and contents of
+    the attribute files to remain consistent in the absence of a version
+    attribute change in the context of a given attribute.

+Linux Magic System Request Key Hacks
+====================================
+
+Documentation for sysrq.c
+
+What is the magic SysRq key?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is a 'magical' key combo you can hit which the kernel will respond to
+regardless of whatever else it is doing, unless it is completely locked up.
+
+How do I enable the magic SysRq key?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You need to say "yes" to 'Magic SysRq key (CONFIG_MAGIC_SYSRQ)' when
+configuring the kernel. When running a kernel with SysRq compiled in,
+/proc/sys/kernel/sysrq controls the functions allowed to be invoked via
+the SysRq key. The default value in this file is set by the
+CONFIG_MAGIC_SYSRQ_DEFAULT_ENABLE config symbol, which itself defaults
+to 1. Here is the list of possible values in /proc/sys/kernel/sysrq:
+
+   -  0 - disable sysrq completely
+   -  1 - enable all functions of sysrq
+   - >1 - bitmask of allowed sysrq functions (see below for detailed function
+     description)::
+
+          2 =   0x2 - enable control of console logging level
+          4 =   0x4 - enable control of keyboard (SAK, unraw)
+          8 =   0x8 - enable debugging dumps of processes etc.
+         16 =  0x10 - enable sync command
+         32 =  0x20 - enable remount read-only
+         64 =  0x40 - enable signalling of processes (term, kill, oom-kill)
+        128 =  0x80 - allow reboot/poweroff
+        256 = 0x100 - allow nicing of all RT tasks
+
+You can set the value in the file by the following command::
+
+    echo "number" >/proc/sys/kernel/sysrq
+
+The number may be written here either as decimal or as hexadecimal
+with the 0x prefix. CONFIG_MAGIC_SYSRQ_DEFAULT_ENABLE must always be
+written in hexadecimal.
+
+Note that the value of ``/proc/sys/kernel/sysrq`` influences only the invocation
+via a keyboard. Invocation of any operation via ``/proc/sysrq-trigger`` is
+always allowed (by a user with admin privileges).
+
+How do I use the magic SysRq key?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On x86   - You press the key combo :kbd:`ALT-SysRq-<command key>`.
+
+.. note::
+	   Some
+           keyboards may not have a key labeled 'SysRq'. The 'SysRq' key is
+           also known as the 'Print Screen' key. Also some keyboards cannot
+	   handle so many keys being pressed at the same time, so you might
+	   have better luck with press :kbd:`Alt`, press :kbd:`SysRq`,
+	   release :kbd:`SysRq`, press :kbd:`<command key>`, release everything.
+
+On SPARC - You press :kbd:`ALT-STOP-<command key>`, I believe.
+
+On the serial console (PC style standard serial ports only)
+        You send a ``BREAK``, then within 5 seconds a command key. Sending
+        ``BREAK`` twice is interpreted as a normal BREAK.
+
+On PowerPC
+	Press :kbd:`ALT - Print Screen` (or :kbd:`F13`) - :kbd:`<command key>`,
+        :kbd:`Print Screen` (or :kbd:`F13`) - :kbd:`<command key>` may suffice.
+
+On other
+	If you know of the key combos for other architectures, please
+        let me know so I can add them to this section.
+
+On all
+	write a character to /proc/sysrq-trigger.  e.g.::
+
+		echo t > /proc/sysrq-trigger
+
+What are the 'command' keys?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+=========== ===================================================================
+Command	    Function

+
+``g``	    Used by kgdb (kernel debugger)

+
+``y``	    Show global CPU Registers [SPARC-64 specific]
+
+``z``	    Dump the ftrace buffer
+
+``0``-``9`` Sets the console log level, controlling which kernel messages
+            will be printed to your console. (``0``, for example would make
+            it so that only emergency messages like PANICs or OOPSes would
+            make it to your console.)
+=========== ===================================================================
+
+Okay, so what can I use them for?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Well, unraw(r) is very handy when your X server or a svgalib program crashes.
+
+sak(k) (Secure Access Key) is useful when you want to be sure there is no
+trojan program running at console which could grab your password
+when you would try to login. It will kill all programs on given console,
+thus letting you make sure that the login prompt you see is actually
+the one from init, not some trojan program.
+
+.. important::
+
+   In its true form it is not a true SAK like the one in a
+   c2 compliant system, and it should not be mistaken as
+   such.
+
+It seems others find it useful as (System Attention Key) which is
+useful when you want to exit a program that will not let you switch consoles.
+(For example, X or a svgalib program.)
+
+``reboot(b)`` is good when you're unable to shut down. But you should also
+``sync(s)`` and ``umount(u)`` first.
+
+``crash(c)`` can be used to manually trigger a crashdump when the system is hung.
+Note that this just triggers a crash if there is no dump mechanism available.
+
+``sync(s)`` is great when your system is locked up, it allows you to sync your
+disks and will certainly lessen the chance of data loss and fscking. Note
+that the sync hasn't taken place until you see the "OK" and "Done" appear
+on the screen. (If the kernel is really in strife, you may not ever get the
+OK or Done message...)
+
+``umount(u)`` is basically useful in the same ways as ``sync(s)``. I generally
+``sync(s)``, ``umount(u)``, then ``reboot(b)`` when my system locks. It's saved
+me many a fsck. Again, the unmount (remount read-only) hasn't taken place until
+you see the "OK" and "Done" message appear on the screen.
+
+The loglevels ``0``-``9`` are useful when your console is being flooded with
+kernel messages you do not want to see. Selecting ``0`` will prevent all but
+the most urgent kernel messages from reaching your console. (They will
+still be logged if syslogd/klogd are alive, though.)
+
+``term(e)`` and ``kill(i)`` are useful if you have some sort of runaway process
+you are unable to kill any other way, especially if it's spawning other
+processes.
+
+"just thaw ``it(j)``" is useful if your system becomes unresponsive due to a
+frozen (probably root) filesystem via the FIFREEZE ioctl.
+
+Sometimes SysRq seems to get 'stuck' after using it, what can I do?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+That happens to me, also. I've found that tapping shift, alt, and control
+on both sides of the keyboard, and hitting an invalid sysrq sequence again
+will fix the problem. (i.e., something like :kbd:`alt-sysrq-z`). Switching to
+another virtual console (:kbd:`ALT+Fn`) and then back again should also help.
+
+I hit SysRq, but nothing seems to happen, what's wrong?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are some keyboards that produce a different keycode for SysRq than the
+pre-defined value of 99 (see ``KEY_SYSRQ`` in ``include/linux/input.h``), or
+which don't have a SysRq key at all. In these cases, run ``showkey -s`` to find
+an appropriate scancode sequence, and use ``setkeycodes <sequence> 99`` to map
+this sequence to the usual SysRq code (e.g., ``setkeycodes e05b 99``). It's
+probably best to put this command in a boot script. Oh, and by the way, you
+exit ``showkey`` by not typing anything for ten seconds.
+
+I want to add SysRQ key events to a module, how does it work?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In order to register a basic function with the table, you must first include
+the header ``include/linux/sysrq.h``, this will define everything else you need.
+Next, you must create a ``sysrq_key_op`` struct, and populate it with A) the key
+handler function you will use, B) a help_msg string, that will print when SysRQ
+prints help, and C) an action_msg string, that will print right before your
+handler is called. Your handler must conform to the prototype in 'sysrq.h'.
+
+After the ``sysrq_key_op`` is created, you can call the kernel function
+``register_sysrq_key(int key, struct sysrq_key_op *op_p);`` this will
+register the operation pointed to by ``op_p`` at table key 'key',
+if that slot in the table is blank. At module unload time, you must call
+the function ``unregister_sysrq_key(int key, struct sysrq_key_op *op_p)``, which
+will remove the key op pointed to by 'op_p' from the key 'key', if and only if
+it is currently registered in that slot. This is in case the slot has been
+overwritten since you registered it.
+
+The Magic SysRQ system works by registering key operations against a key op
+lookup table, which is defined in 'drivers/tty/sysrq.c'. This key table has
+a number of operations registered into it at compile time, but is mutable,
+and 2 functions are exported for interface to it::
+
+	register_sysrq_key and unregister_sysrq_key.
+
+Of course, never ever leave an invalid pointer in the table. I.e., when
+your module that called register_sysrq_key() exits, it must call
+unregister_sysrq_key() to clean up the sysrq key table entry that it used.
+Null pointers in the table are always safe. :)
+
+If for some reason you feel the need to call the handle_sysrq function from
+within a function called by handle_sysrq, you must be aware that you are in
+a lock (you are also in an interrupt handler, which means don't sleep!), so
+you must call ``__handle_sysrq_nolock`` instead.
+
+When I hit a SysRq key combination only the header appears on the console?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sysrq output is subject to the same console loglevel control as all
+other console output.  This means that if the kernel was booted 'quiet'
+as is common on distro kernels the output may not appear on the actual
+console, even though it will appear in the dmesg buffer, and be accessible
+via the dmesg command and to the consumers of ``/proc/kmsg``.  As a specific
+exception the header line from the sysrq command is passed to all console
+consumers as if the current loglevel was maximum.  If only the header
+is emitted it is almost certain that the kernel loglevel is too low.
+Should you require the output on the console channel then you will need
+to temporarily up the console loglevel using :kbd:`alt-sysrq-8` or::
+
+    echo 8 > /proc/sysrq-trigger
+
+Remember to return the loglevel to normal after triggering the sysrq
+command you are interested in.
+
+I have more questions, who can I ask?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Just ask them on the linux-kernel mailing list:
+	linux-kernel@vger.kernel.org

+Tainted kernels
+---------------
+
+Some oops reports contain the string **'Tainted: '** after the program
+counter. This indicates that the kernel has been tainted by some
+mechanism.  The string is followed by a series of position-sensitive
+characters, each representing a particular tainted value.
+
+  1) 'G' if all modules loaded have a GPL or compatible license, 'P' if
+     any proprietary module has been loaded.  Modules without a
+     MODULE_LICENSE or with a MODULE_LICENSE that is not recognised by
+     insmod as GPL compatible are assumed to be proprietary.
+
+  2) ``F`` if any module was force loaded by ``insmod -f``, ``' '`` if all
+     modules were loaded normally.
+
+  3) ``S`` if the oops occurred on an SMP kernel running on hardware that
+     hasn't been certified as safe to run multiprocessor.
+     Currently this occurs only on various Athlons that are not
+     SMP capable.
+
+  4) ``R`` if a module was force unloaded by ``rmmod -f``, ``' '`` if all
+     modules were unloaded normally.
+
+  5) ``M`` if any processor has reported a Machine Check Exception,
+     ``' '`` if no Machine Check Exceptions have occurred.
+
+  6) ``B`` if a page-release function has found a bad page reference or
+     some unexpected page flags.
+
+  7) ``U`` if a user or user application specifically requested that the
+     Tainted flag be set, ``' '`` otherwise.
+
+  8) ``D`` if the kernel has died recently, i.e. there was an OOPS or BUG.
+
+  9) ``A`` if the ACPI table has been overridden.
+
+ 10) ``W`` if a warning has previously been issued by the kernel.
+     (Though some warnings may set more specific taint flags.)
+
+ 11) ``C`` if a staging driver has been loaded.
+
+ 12) ``I`` if the kernel is working around a severe bug in the platform
+     firmware (BIOS or similar).
+

+Software cursor for VGA
+=======================
+
+by Pavel Machek <pavel@atrey.karlin.mff.cuni.cz>
+and Martin Mares <mj@atrey.karlin.mff.cuni.cz>
+
+Linux now has some ability to manipulate cursor appearance.  Normally,
+you can set the size of hardware cursor.  You can now play a few new
+tricks: you can make your cursor look like a non-blinking red block,
+make it inverse background of the character it's over or to highlight
+that character and still choose whether the original hardware cursor
+should remain visible or not.  There may be other things I have never
+thought of.
+
+The cursor appearance is controlled by a ``<ESC>[?1;2;3c`` escape sequence
+where 1, 2 and 3 are parameters described below. If you omit any of them,
+they will default to zeroes.
+
+first Parameter
+	specifies cursor size::
+
+		0=default
+		1=invisible
+		2=underline,
+		...
+		8=full block
+		+ 16 if you want the software cursor to be applied
+		+ 32 if you want to always change the background color
+		+ 64 if you dislike having the background the same as the
+		     foreground.
+
+	Highlights are ignored for the last two flags.
+
+second parameter
+	selects character attribute bits you want to change
+	(by simply XORing them with the value of this parameter). On standard
+	VGA, the high four bits specify background and the low four the
+	foreground. In both groups, low three bits set color (as in normal
+	color codes used by the console) and the most significant one turns
+	on highlight (or sometimes blinking -- it depends on the configuration
+	of your VGA).
+
+third parameter
+	consists of character attribute bits you want to set.
+
+	Bit setting takes place before bit toggling, so you can simply clear a
+	bit by including it in both the set mask and the toggle mask.
+
+Examples
+--------
+
+To get normal blinking underline, use::
+
+	echo -e '\033[?2c'
+
+To get blinking block, use::
+
+	echo -e '\033[?6c'
+
+To get red non-blinking block, use::
+
+	echo -e '\033[?17;0;64c'

-
-========
-OVERVIEW
-========
-
-This associative array implementation is an object container with the following
-properties:
-
- (1) Objects are opaque pointers.  The implementation does not care where they
-     point (if anywhere) or what they point to (if anything).
-
-     [!] NOTE: Pointers to objects _must_ be zero in the least significant bit.
-
- (2) Objects do not need to contain linkage blocks for use by the array.  This
-     permits an object to be located in multiple arrays simultaneously.
-     Rather, the array is made up of metadata blocks that point to objects.
-
- (3) Objects require index keys to locate them within the array.
-
- (4) Index keys must be unique.  Inserting an object with the same key as one
-     already in the array will replace the old object.
-
- (5) Index keys can be of any length and can be of different lengths.
-
- (6) Index keys should encode the length early on, before any variation due to
-     length is seen.
-
- (7) Index keys can include a hash to scatter objects throughout the array.
-
- (8) The array can iterated over.  The objects will not necessarily come out in
-     key order.
-
- (9) The array can be iterated over whilst it is being modified, provided the
-     RCU readlock is being held by the iterator.  Note, however, under these
-     circumstances, some objects may be seen more than once.  If this is a
-     problem, the iterator should lock against modification.  Objects will not
-     be missed, however, unless deleted.
-
-(10) Objects in the array can be looked up by means of their index key.
-
-(11) Objects can be looked up whilst the array is being modified, provided the
-     RCU readlock is being held by the thread doing the look up.
-
-The implementation uses a tree of 16-pointer nodes internally that are indexed
-on each level by nibbles from the index key in the same manner as in a radix
-tree.  To improve memory efficiency, shortcuts can be emplaced to skip over
-what would otherwise be a series of single-occupancy nodes.  Further, nodes
-pack leaf object pointers into spare space in the node rather than making an
-extra branch until as such time an object needs to be added to a full node.
-
-
-==============
-THE PUBLIC API
-==============
-
-The public API can be found in <linux/assoc_array.h>.  The associative array is
-rooted on the following structure:
-
-	struct assoc_array {
-		...
-	};
-
-The code is selected by enabling CONFIG_ASSOCIATIVE_ARRAY.
-
-
-EDIT SCRIPT
------------
-
-The insertion and deletion functions produce an 'edit script' that can later be
-applied to effect the changes without risking ENOMEM.  This retains the
-preallocated metadata blocks that will be installed in the internal tree and
-keeps track of the metadata blocks that will be removed from the tree when the
-script is applied.
-
-This is also used to keep track of dead blocks and dead objects after the
-script has been applied so that they can be freed later.  The freeing is done
-after an RCU grace period has passed - thus allowing access functions to
-proceed under the RCU read lock.
-
-The script appears as outside of the API as a pointer of the type:
-
-	struct assoc_array_edit;
-
-There are two functions for dealing with the script:
-
- (1) Apply an edit script.
-
-	void assoc_array_apply_edit(struct assoc_array_edit *edit);
-
-     This will perform the edit functions, interpolating various write barriers
-     to permit accesses under the RCU read lock to continue.  The edit script
-     will then be passed to call_rcu() to free it and any dead stuff it points
-     to.
-
- (2) Cancel an edit script.
-
-	void assoc_array_cancel_edit(struct assoc_array_edit *edit);
-
-     This frees the edit script and all preallocated memory immediately.  If
-     this was for insertion, the new object is _not_ released by this function,
-     but must rather be released by the caller.
-
-These functions are guaranteed not to fail.
-
-
-OPERATIONS TABLE
-----------------
-
-Various functions take a table of operations:
-
-	struct assoc_array_ops {
-		...
-	};
-
-This points to a number of methods, all of which need to be provided:
-
- (1) Get a chunk of index key from caller data:
-
-	unsigned long (*get_key_chunk)(const void *index_key, int level);
-
-     This should return a chunk of caller-supplied index key starting at the
-     *bit* position given by the level argument.  The level argument will be a
-     multiple of ASSOC_ARRAY_KEY_CHUNK_SIZE and the function should return
-     ASSOC_ARRAY_KEY_CHUNK_SIZE bits.  No error is possible.
-
-
- (2) Get a chunk of an object's index key.
-
-	unsigned long (*get_object_key_chunk)(const void *object, int level);
-
-     As the previous function, but gets its data from an object in the array
-     rather than from a caller-supplied index key.
-
-
- (3) See if this is the object we're looking for.
-
-	bool (*compare_object)(const void *object, const void *index_key);
-
-     Compare the object against an index key and return true if it matches and
-     false if it doesn't.
-
-
- (4) Diff the index keys of two objects.
-
-	int (*diff_objects)(const void *object, const void *index_key);
-
-     Return the bit position at which the index key of the specified object
-     differs from the given index key or -1 if they are the same.
-
-
- (5) Free an object.
-
-	void (*free_object)(void *object);
-
-     Free the specified object.  Note that this may be called an RCU grace
-     period after assoc_array_apply_edit() was called, so synchronize_rcu() may
-     be necessary on module unloading.
-
-
-MANIPULATION FUNCTIONS
-----------------------
-
-There are a number of functions for manipulating an associative array:
-
- (1) Initialise an associative array.
-
-	void assoc_array_init(struct assoc_array *array);
-
-     This initialises the base structure for an associative array.  It can't
-     fail.
-
-
- (2) Insert/replace an object in an associative array.
-
-	struct assoc_array_edit *
-	assoc_array_insert(struct assoc_array *array,
-			   const struct assoc_array_ops *ops,
-			   const void *index_key,
-			   void *object);
-
-     This inserts the given object into the array.  Note that the least
-     significant bit of the pointer must be zero as it's used to type-mark
-     pointers internally.
-
-     If an object already exists for that key then it will be replaced with the
-     new object and the old one will be freed automatically.
-
-     The index_key argument should hold index key information and is
-     passed to the methods in the ops table when they are called.
-
-     This function makes no alteration to the array itself, but rather returns
-     an edit script that must be applied.  -ENOMEM is returned in the case of
-     an out-of-memory error.
-
-     The caller should lock exclusively against other modifiers of the array.
-
-
- (3) Delete an object from an associative array.
-
-	struct assoc_array_edit *
-	assoc_array_delete(struct assoc_array *array,
-			   const struct assoc_array_ops *ops,
-			   const void *index_key);
-
-     This deletes an object that matches the specified data from the array.
-
-     The index_key argument should hold index key information and is
-     passed to the methods in the ops table when they are called.
-
-     This function makes no alteration to the array itself, but rather returns
-     an edit script that must be applied.  -ENOMEM is returned in the case of
-     an out-of-memory error.  NULL will be returned if the specified object is
-     not found within the array.
-
-     The caller should lock exclusively against other modifiers of the array.
-
-
- (4) Delete all objects from an associative array.
-
-	struct assoc_array_edit *
-	assoc_array_clear(struct assoc_array *array,
-			  const struct assoc_array_ops *ops);
-
-     This deletes all the objects from an associative array and leaves it
-     completely empty.
-
-     This function makes no alteration to the array itself, but rather returns
-     an edit script that must be applied.  -ENOMEM is returned in the case of
-     an out-of-memory error.
-
-     The caller should lock exclusively against other modifiers of the array.
-
-
- (5) Destroy an associative array, deleting all objects.
-
-	void assoc_array_destroy(struct assoc_array *array,
-				 const struct assoc_array_ops *ops);
-
-     This destroys the contents of the associative array and leaves it
-     completely empty.  It is not permitted for another thread to be traversing
-     the array under the RCU read lock at the same time as this function is
-     destroying it as no RCU deferral is performed on memory release -
-     something that would require memory to be allocated.
-
-     The caller should lock exclusively against other modifiers and accessors
-     of the array.
-
-
- (6) Garbage collect an associative array.
-
-	int assoc_array_gc(struct assoc_array *array,
-			   const struct assoc_array_ops *ops,
-			   bool (*iterator)(void *object, void *iterator_data),
-			   void *iterator_data);
-
-     This iterates over the objects in an associative array and passes each one
-     to iterator().  If iterator() returns true, the object is kept.  If it
-     returns false, the object will be freed.  If the iterator() function
-     returns true, it must perform any appropriate refcount incrementing on the
-     object before returning.
-
-     The internal tree will be packed down if possible as part of the iteration
-     to reduce the number of nodes in it.
-
-     The iterator_data is passed directly to iterator() and is otherwise
-     ignored by the function.
-
-     The function will return 0 if successful and -ENOMEM if there wasn't
-     enough memory.
-
-     It is possible for other threads to iterate over or search the array under
-     the RCU read lock whilst this function is in progress.  The caller should
-     lock exclusively against other modifiers of the array.
-
-
-ACCESS FUNCTIONS
-----------------
-
-There are two functions for accessing an associative array:
-
- (1) Iterate over all the objects in an associative array.
-
-	int assoc_array_iterate(const struct assoc_array *array,
-				int (*iterator)(const void *object,
-						void *iterator_data),
-				void *iterator_data);
-
-     This passes each object in the array to the iterator callback function.
-     iterator_data is private data for that function.
-
-     This may be used on an array at the same time as the array is being
-     modified, provided the RCU read lock is held.  Under such circumstances,
-     it is possible for the iteration function to see some objects twice.  If
-     this is a problem, then modification should be locked against.  The
-     iteration algorithm should not, however, miss any objects.
-
-     The function will return 0 if no objects were in the array or else it will
-     return the result of the last iterator function called.  Iteration stops
-     immediately if any call to the iteration function results in a non-zero
-     return.
-
-
- (2) Find an object in an associative array.
-
-	void *assoc_array_find(const struct assoc_array *array,
-			       const struct assoc_array_ops *ops,
-			       const void *index_key);
-
-     This walks through the array's internal tree directly to the object
-     specified by the index key..
-
-     This may be used on an array at the same time as the array is being
-     modified, provided the RCU read lock is held.
-
-     The function will return the object if found (and set *_type to the object
-     type) or will return NULL if the object was not found.
-
-
-INDEX KEY FORM
---------------
-
-The index key can be of any form, but since the algorithms aren't told how long
-the key is, it is strongly recommended that the index key includes its length
-very early on before any variation due to the length would have an effect on
-comparisons.
-
-This will cause leaves with different length keys to scatter away from each
-other - and those with the same length keys to cluster together.
-
-It is also recommended that the index key begin with a hash of the rest of the
-key to maximise scattering throughout keyspace.
-
-The better the scattering, the wider and lower the internal tree will be.
-
-Poor scattering isn't too much of a problem as there are shortcuts and nodes
-can contain mixtures of leaves and metadata pointers.
-
-The index key is read in chunks of machine word.  Each chunk is subdivided into
-one nibble (4 bits) per level, so on a 32-bit CPU this is good for 8 levels and
-on a 64-bit CPU, 16 levels.  Unless the scattering is really poor, it is
-unlikely that more than one word of any particular index key will have to be
-used.
-
-
-=================
-INTERNAL WORKINGS
-=================
-
-The associative array data structure has an internal tree.  This tree is
-constructed of two types of metadata blocks: nodes and shortcuts.
-
-A node is an array of slots.  Each slot can contain one of four things:
-
- (*) A NULL pointer, indicating that the slot is empty.
-
- (*) A pointer to an object (a leaf).
-
- (*) A pointer to a node at the next level.
-
- (*) A pointer to a shortcut.
-
-
-BASIC INTERNAL TREE LAYOUT
---------------------------
-
-Ignoring shortcuts for the moment, the nodes form a multilevel tree.  The index
-key space is strictly subdivided by the nodes in the tree and nodes occur on
-fixed levels.  For example:
-
- Level:	0		1		2		3
-	===============	===============	===============	===============
-							NODE D
-			NODE B		NODE C	+------>+---+
-		+------>+---+	+------>+---+	|	| 0 |
-	NODE A	|	| 0 |	|	| 0 |	|	+---+
-	+---+	|	+---+	|	+---+	|	:   :
-	| 0 |	|	:   :	|	:   :	|	+---+
-	+---+	|	+---+	|	+---+	|	| f |
-	| 1 |---+	| 3 |---+	| 7 |---+	+---+
-	+---+		+---+		+---+
-	:   :		:   :		| 8 |---+
-	+---+		+---+		+---+	|	NODE E
-	| e |---+	| f |		:   :   +------>+---+
-	+---+	|	+---+		+---+		| 0 |
-	| f |	|			| f |		+---+
-	+---+	|			+---+		:   :
-		|	NODE F				+---+
-		+------>+---+				| f |
-			| 0 |		NODE G		+---+
-			+---+	+------>+---+
-			:   :	|	| 0 |
-			+---+	|	+---+
-			| 6 |---+	:   :
-			+---+		+---+
-			:   :		| f |
-			+---+		+---+
-			| f |
-			+---+
-
-In the above example, there are 7 nodes (A-G), each with 16 slots (0-f).
-Assuming no other meta data nodes in the tree, the key space is divided thusly:
-
-	KEY PREFIX	NODE
-	==========	====
-	137*		D
-	138*		E
-	13[0-69-f]*	C
-	1[0-24-f]*	B
-	e6*		G
-	e[0-57-f]*	F

-To save memory, if a node can hold all the leaves in its portion of keyspace,
-then the node will have all those leaves in it and will not have any metadata
-pointers - even if some of those leaves would like to be in the same slot.
-
-A node can contain a heterogeneous mix of leaves and metadata pointers.
-Metadata pointers must be in the slots that match their subdivisions of key
-space.  The leaves can be in any slot not occupied by a metadata pointer.  It
-is guaranteed that none of the leaves in a node will match a slot occupied by a
-metadata pointer.  If the metadata pointer is there, any leaf whose key matches
-the metadata key prefix must be in the subtree that the metadata pointer points
-to.
-
-In the above example list of index keys, node A will contain:

-
-
-SHORTCUTS
----------
-
-Shortcuts are metadata records that jump over a piece of keyspace.  A shortcut
-is a replacement for a series of single-occupancy nodes ascending through the
-levels.  Shortcuts exist to save memory and to speed up traversal.
-
-It is possible for the root of the tree to be a shortcut - say, for example,
-the tree contains at least 17 nodes all with key prefix '1111'.  The insertion
-algorithm will insert a shortcut to skip over the '1111' keyspace in a single
-bound and get to the fourth level where these actually become different.
-
-
-SPLITTING AND COLLAPSING NODES
-------------------------------
-
-Each node has a maximum capacity of 16 leaves and metadata pointers.  If the
-insertion algorithm finds that it is trying to insert a 17th object into a
-node, that node will be split such that at least two leaves that have a common
-key segment at that level end up in a separate node rooted on that slot for
-that common key segment.
-
-If the leaves in a full node and the leaf that is being inserted are
-sufficiently similar, then a shortcut will be inserted into the tree.
-
-When the number of objects in the subtree rooted at a node falls to 16 or
-fewer, then the subtree will be collapsed down to a single node - and this will
-ripple towards the root if possible.
-
-
-NON-RECURSIVE ITERATION
------------------------
-
-Each node and shortcut contains a back pointer to its parent and the number of
-slot in that parent that points to it.  None-recursive iteration uses these to
-proceed rootwards through the tree, going to the parent node, slot N + 1 to
-make sure progress is made without the need for a stack.
-
-The backpointers, however, make simultaneous alteration and iteration tricky.
-
-
-SIMULTANEOUS ALTERATION AND ITERATION
--------------------------------------
-
-There are a number of cases to consider:
-
- (1) Simple insert/replace.  This involves simply replacing a NULL or old
-     matching leaf pointer with the pointer to the new leaf after a barrier.
-     The metadata blocks don't change otherwise.  An old leaf won't be freed
-     until after the RCU grace period.
-
- (2) Simple delete.  This involves just clearing an old matching leaf.  The
-     metadata blocks don't change otherwise.  The old leaf won't be freed until
-     after the RCU grace period.
-
- (3) Insertion replacing part of a subtree that we haven't yet entered.  This
-     may involve replacement of part of that subtree - but that won't affect
-     the iteration as we won't have reached the pointer to it yet and the
-     ancestry blocks are not replaced (the layout of those does not change).
-
- (4) Insertion replacing nodes that we're actively processing.  This isn't a
-     problem as we've passed the anchoring pointer and won't switch onto the
-     new layout until we follow the back pointers - at which point we've
-     already examined the leaves in the replaced node (we iterate over all the
-     leaves in a node before following any of its metadata pointers).
-
-     We might, however, re-see some leaves that have been split out into a new
-     branch that's in a slot further along than we were at.
-
- (5) Insertion replacing nodes that we're processing a dependent branch of.
-     This won't affect us until we follow the back pointers.  Similar to (4).
-
- (6) Deletion collapsing a branch under us.  This doesn't affect us because the
-     back pointers will get us back to the parent of the new node before we
-     could see the new node.  The entire collapsed subtree is thrown away
-     unchanged - and will still be rooted on the same slot, so we shouldn't
-     process it a second time as we'll go back to slot + 1.
-
-Note:
-
- (*) Under some circumstances, we need to simultaneously change the parent
-     pointer and the parent slot pointer on a node (say, for example, we
-     inserted another node before it and moved it up a level).  We cannot do
-     this without locking against a read - so we have to replace that node too.
-
-     However, when we're changing a shortcut into a node this isn't a problem
-     as shortcuts only have one slot and so the parent slot number isn't used
-     when traversing backwards over one.  This means that it's okay to change
-     the slot number first - provided suitable barriers are used to make sure
-     the parent slot number is read after the back pointer.
-
-Obsolete blocks and leaves are freed up after an RCU grace period has passed,
-so as long as anyone doing walking or iteration holds the RCU read lock, the
-old superstructure should not go away on them.

-How to deal with bad memory e.g. reported by memtest86+ ?
-#########################################################
-
-There are three possibilities I know of:
-
-1) Reinsert/swap the memory modules
-
-2) Buy new modules (best!) or try to exchange the memory
-   if you have spare-parts
-
-3) Use BadRAM or memmap
-
-This Howto is about number 3) .
-
-
-BadRAM
-######
-BadRAM is the actively developed and available as kernel-patch
-here:  http://rick.vanrein.org/linux/badram/
-
-For more details see the BadRAM documentation.
-
-memmap
-######
-
-memmap is already in the kernel and usable as kernel-parameter at
-boot-time.  Its syntax is slightly strange and you may need to
-calculate the values by yourself!
-
-Syntax to exclude a memory area (see kernel-parameters.txt for details):
-memmap=<size>$<address>
-
-Example: memtest86+ reported here errors at address 0x18691458, 0x18698424 and
-         some others. All had 0x1869xxxx in common, so I chose a pattern of
-         0x18690000,0xffff0000.
-
-With the numbers of the example above:
-memmap=64K$0x18690000
- or
-memmap=0x10000$0x18690000

-     Kernel Support for miscellaneous (your favourite) Binary Formats v1.1
-     =====================================================================
-
-This Kernel feature allows you to invoke almost (for restrictions see below)
-every program by simply typing its name in the shell.
-This includes for example compiled Java(TM), Python or Emacs programs.
-
-To achieve this you must tell binfmt_misc which interpreter has to be invoked
-with which binary. Binfmt_misc recognises the binary-type by matching some bytes
-at the beginning of the file with a magic byte sequence (masking out specified
-bits) you have supplied. Binfmt_misc can also recognise a filename extension
-aka '.com' or '.exe'.
-
-First you must mount binfmt_misc:
-	mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc 
-
-To actually register a new binary type, you have to set up a string looking like
-:name:type:offset:magic:mask:interpreter:flags (where you can choose the ':'
-upon your needs) and echo it to /proc/sys/fs/binfmt_misc/register.
-
-Here is what the fields mean:
- - 'name' is an identifier string. A new /proc file will be created with this
-   name below /proc/sys/fs/binfmt_misc; cannot contain slashes '/' for obvious
-   reasons.
- - 'type' is the type of recognition. Give 'M' for magic and 'E' for extension.
- - 'offset' is the offset of the magic/mask in the file, counted in bytes. This
-   defaults to 0 if you omit it (i.e. you write ':name:type::magic...'). Ignored
-   when using filename extension matching.
- - 'magic' is the byte sequence binfmt_misc is matching for. The magic string
-   may contain hex-encoded characters like \x0a or \xA4. Note that you must
-   escape any NUL bytes; parsing halts at the first one. In a shell environment
-   you might have to write \\x0a to prevent the shell from eating your \.
-   If you chose filename extension matching, this is the extension to be
-   recognised (without the '.', the \x0a specials are not allowed). Extension
-   matching is case sensitive, and slashes '/' are not allowed!
- - 'mask' is an (optional, defaults to all 0xff) mask. You can mask out some
-   bits from matching by supplying a string like magic and as long as magic.
-   The mask is anded with the byte sequence of the file. Note that you must
-   escape any NUL bytes; parsing halts at the first one. Ignored when using
-   filename extension matching.
- - 'interpreter' is the program that should be invoked with the binary as first
-   argument (specify the full path)
- - 'flags' is an optional field that controls several aspects of the invocation
-   of the interpreter. It is a string of capital letters, each controls a
-   certain aspect. The following flags are supported -
-      'P' - preserve-argv[0]. Legacy behavior of binfmt_misc is to overwrite
-            the original argv[0] with the full path to the binary. When this
-            flag is included, binfmt_misc will add an argument to the argument
-            vector for this purpose, thus preserving the original argv[0].
-            e.g. If your interp is set to /bin/foo and you run `blah` (which is
-            in /usr/local/bin), then the kernel will execute /bin/foo with
-            argv[] set to ["/bin/foo", "/usr/local/bin/blah", "blah"].  The
-            interp has to be aware of this so it can execute /usr/local/bin/blah
-            with argv[] set to ["blah"].
-      'O' - open-binary. Legacy behavior of binfmt_misc is to pass the full path
-            of the binary to the interpreter as an argument. When this flag is
-            included, binfmt_misc will open the file for reading and pass its
-            descriptor as an argument, instead of the full path, thus allowing
-            the interpreter to execute non-readable binaries. This feature
-            should be used with care - the interpreter has to be trusted not to
-            emit the contents of the non-readable binary.
-      'C' - credentials. Currently, the behavior of binfmt_misc is to calculate
-            the credentials and security token of the new process according to
-            the interpreter. When this flag is included, these attributes are
-            calculated according to the binary. It also implies the 'O' flag.
-            This feature should be used with care as the interpreter
-            will run with root permissions when a setuid binary owned by root
-            is run with binfmt_misc.
-      'F' - fix binary.  The usual behaviour of binfmt_misc is to spawn the
-      	    binary lazily when the misc format file is invoked.  However,
-	    this doesn't work very well in the face of mount namespaces and
-	    changeroots, so the F mode opens the binary as soon as the
-	    emulation is installed and uses the opened image to spawn the
-	    emulator, meaning it is always available once installed,
-	    regardless of how the environment changes.
-
-
-There are some restrictions:
- - the whole register string may not exceed 1920 characters
- - the magic must reside in the first 128 bytes of the file, i.e.
-   offset+size(magic) has to be less than 128
- - the interpreter string may not exceed 127 characters
-
-To use binfmt_misc you have to mount it first. You can mount it with
-"mount -t binfmt_misc none /proc/sys/fs/binfmt_misc" command, or you can add
-a line "none  /proc/sys/fs/binfmt_misc binfmt_misc defaults 0 0" to your
-/etc/fstab so it auto mounts on boot.
-
-You may want to add the binary formats in one of your /etc/rc scripts during
-boot-up. Read the manual of your init program to figure out how to do this
-right.
-
-Think about the order of adding entries! Later added entries are matched first!
-
-
-A few examples (assumed you are in /proc/sys/fs/binfmt_misc):
-
-- enable support for em86 (like binfmt_em86, for Alpha AXP only):
-  echo ':i386:M::\x7fELF\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x03:\xff\xff\xff\xff\xff\xfe\xfe\xff\xff\xff\xff\xff\xff\xff\xff\xff\xfb\xff\xff:/bin/em86:' > register
-  echo ':i486:M::\x7fELF\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\x06:\xff\xff\xff\xff\xff\xfe\xfe\xff\xff\xff\xff\xff\xff\xff\xff\xff\xfb\xff\xff:/bin/em86:' > register
-
-- enable support for packed DOS applications (pre-configured dosemu hdimages):
-  echo ':DEXE:M::\x0eDEX::/usr/bin/dosexec:' > register
-
-- enable support for Windows executables using wine:
-  echo ':DOSWin:M::MZ::/usr/local/bin/wine:' > register
-
-For java support see Documentation/java.txt
-
-
-You can enable/disable binfmt_misc or one binary type by echoing 0 (to disable)
-or 1 (to enable) to /proc/sys/fs/binfmt_misc/status or /proc/.../the_name.
-Catting the file tells you the current status of binfmt_misc/the entry.
-
-You can remove one entry or all entries by echoing -1 to /proc/.../the_name
-or /proc/sys/fs/binfmt_misc/status.
-
-
-HINTS:
-======
-
-If you want to pass special arguments to your interpreter, you can
-write a wrapper script for it. See Documentation/java.txt for an
-example.
-
-Your interpreter should NOT look in the PATH for the filename; the kernel
-passes it the full filename (or the file descriptor) to use.  Using $PATH can
-cause unexpected behaviour and can be a security hazard.

-
-To get early boot messages on a braille device (before userspace screen
-readers can start), you first need to compile the support for the usual serial
-console (see serial-console.txt), and for braille device (in Device Drivers -
-Accessibility).
-
-Then you need to specify a console=brl, option on the kernel command line, the
-format is:
-
-	console=brl,serial_options...
-
-where serial_options... are the same as described in serial-console.txt
-
-So for instance you can use console=brl,ttyS0 if the braille device is connected
-to the first serial port, and console=brl,ttyS0,115200 to override the baud rate
-to 115200, etc.
-
-By default, the braille device will just show the last kernel message (console
-mode).  To review previous messages, press the Insert key to switch to the VT
-review mode.  In review mode, the arrow keys permit to browse in the VT content,
-page up/down keys go at the top/bottom of the screen, and the home key goes back
-to the cursor, hence providing very basic screen reviewing facility.
-
-Sound feedback can be obtained by adding the braille_console.sound=1 kernel
-parameter.
-
-For simplicity, only one braille console can be enabled, other uses of
-console=brl,... will be discarded.  Also note that it does not interfere with
-the console selection mechanism described in serial-console.txt
-
-For now, only the VisioBraille device is supported.

+========================================
+Generic Associative Array Implementation
+========================================
+
+Overview
+========
+
+This associative array implementation is an object container with the following
+properties:
+
+1. Objects are opaque pointers.  The implementation does not care where they
+   point (if anywhere) or what they point to (if anything).
+.. note:: Pointers to objects _must_ be zero in the least significant bit.
+
+2. Objects do not need to contain linkage blocks for use by the array.  This
+   permits an object to be located in multiple arrays simultaneously.
+   Rather, the array is made up of metadata blocks that point to objects.
+
+3. Objects require index keys to locate them within the array.
+
+4. Index keys must be unique.  Inserting an object with the same key as one
+   already in the array will replace the old object.
+
+5. Index keys can be of any length and can be of different lengths.
+
+6. Index keys should encode the length early on, before any variation due to
+   length is seen.
+
+7. Index keys can include a hash to scatter objects throughout the array.
+
+8. The array can iterated over.  The objects will not necessarily come out in
+   key order.
+
+9. The array can be iterated over whilst it is being modified, provided the
+   RCU readlock is being held by the iterator.  Note, however, under these
+   circumstances, some objects may be seen more than once.  If this is a
+   problem, the iterator should lock against modification.  Objects will not
+   be missed, however, unless deleted.
+
+10. Objects in the array can be looked up by means of their index key.
+
+11. Objects can be looked up whilst the array is being modified, provided the
+    RCU readlock is being held by the thread doing the look up.
+
+The implementation uses a tree of 16-pointer nodes internally that are indexed
+on each level by nibbles from the index key in the same manner as in a radix
+tree.  To improve memory efficiency, shortcuts can be emplaced to skip over
+what would otherwise be a series of single-occupancy nodes.  Further, nodes
+pack leaf object pointers into spare space in the node rather than making an
+extra branch until as such time an object needs to be added to a full node.
+
+
+The Public API
+==============
+
+The public API can be found in ``<linux/assoc_array.h>``.  The associative
+array is rooted on the following structure::
+
+    struct assoc_array {
+            ...
+    };
+
+The code is selected by enabling ``CONFIG_ASSOCIATIVE_ARRAY`` with::
+
+    ./script/config -e ASSOCIATIVE_ARRAY
+
+
+Edit Script
+-----------
+
+The insertion and deletion functions produce an 'edit script' that can later be
+applied to effect the changes without risking ``ENOMEM``. This retains the
+preallocated metadata blocks that will be installed in the internal tree and
+keeps track of the metadata blocks that will be removed from the tree when the
+script is applied.
+
+This is also used to keep track of dead blocks and dead objects after the
+script has been applied so that they can be freed later.  The freeing is done
+after an RCU grace period has passed - thus allowing access functions to
+proceed under the RCU read lock.
+
+The script appears as outside of the API as a pointer of the type::
+
+    struct assoc_array_edit;
+
+There are two functions for dealing with the script:
+
+1. Apply an edit script::
+
+    void assoc_array_apply_edit(struct assoc_array_edit *edit);
+
+This will perform the edit functions, interpolating various write barriers
+to permit accesses under the RCU read lock to continue.  The edit script
+will then be passed to ``call_rcu()`` to free it and any dead stuff it points
+to.
+
+2. Cancel an edit script::
+
+    void assoc_array_cancel_edit(struct assoc_array_edit *edit);
+
+This frees the edit script and all preallocated memory immediately. If
+this was for insertion, the new object is _not_ released by this function,
+but must rather be released by the caller.
+
+These functions are guaranteed not to fail.
+
+
+Operations Table
+----------------
+
+Various functions take a table of operations::
+
+    struct assoc_array_ops {
+            ...
+    };
+
+This points to a number of methods, all of which need to be provided:
+
+1. Get a chunk of index key from caller data::
+
+    unsigned long (*get_key_chunk)(const void *index_key, int level);
+
+This should return a chunk of caller-supplied index key starting at the
+*bit* position given by the level argument.  The level argument will be a
+multiple of ``ASSOC_ARRAY_KEY_CHUNK_SIZE`` and the function should return
+``ASSOC_ARRAY_KEY_CHUNK_SIZE bits``.  No error is possible.
+
+
+2. Get a chunk of an object's index key::
+
+    unsigned long (*get_object_key_chunk)(const void *object, int level);
+
+As the previous function, but gets its data from an object in the array
+rather than from a caller-supplied index key.
+
+
+3. See if this is the object we're looking for::
+
+    bool (*compare_object)(const void *object, const void *index_key);
+
+Compare the object against an index key and return ``true`` if it matches and
+``false`` if it doesn't.
+
+
+4. Diff the index keys of two objects::
+
+    int (*diff_objects)(const void *object, const void *index_key);
+
+Return the bit position at which the index key of the specified object
+differs from the given index key or -1 if they are the same.
+
+
+5. Free an object::
+
+    void (*free_object)(void *object);
+
+Free the specified object.  Note that this may be called an RCU grace period
+after ``assoc_array_apply_edit()`` was called, so ``synchronize_rcu()`` may be
+necessary on module unloading.
+
+
+Manipulation Functions
+----------------------
+
+There are a number of functions for manipulating an associative array:
+
+1. Initialise an associative array::
+
+    void assoc_array_init(struct assoc_array *array);
+
+This initialises the base structure for an associative array.  It can't fail.
+
+
+2. Insert/replace an object in an associative array::
+
+    struct assoc_array_edit *
+    assoc_array_insert(struct assoc_array *array,
+                       const struct assoc_array_ops *ops,
+                       const void *index_key,
+                       void *object);
+
+This inserts the given object into the array.  Note that the least
+significant bit of the pointer must be zero as it's used to type-mark
+pointers internally.
+
+If an object already exists for that key then it will be replaced with the
+new object and the old one will be freed automatically.
+
+The ``index_key`` argument should hold index key information and is
+passed to the methods in the ops table when they are called.
+
+This function makes no alteration to the array itself, but rather returns
+an edit script that must be applied.  ``-ENOMEM`` is returned in the case of
+an out-of-memory error.
+
+The caller should lock exclusively against other modifiers of the array.
+
+
+3. Delete an object from an associative array::
+
+    struct assoc_array_edit *
+    assoc_array_delete(struct assoc_array *array,
+                       const struct assoc_array_ops *ops,
+                       const void *index_key);
+
+This deletes an object that matches the specified data from the array.
+
+The ``index_key`` argument should hold index key information and is
+passed to the methods in the ops table when they are called.
+
+This function makes no alteration to the array itself, but rather returns
+an edit script that must be applied.  ``-ENOMEM`` is returned in the case of
+an out-of-memory error.  ``NULL`` will be returned if the specified object is
+not found within the array.
+
+The caller should lock exclusively against other modifiers of the array.
+
+
+4. Delete all objects from an associative array::
+
+    struct assoc_array_edit *
+    assoc_array_clear(struct assoc_array *array,
+                      const struct assoc_array_ops *ops);
+
+This deletes all the objects from an associative array and leaves it
+completely empty.
+
+This function makes no alteration to the array itself, but rather returns
+an edit script that must be applied.  ``-ENOMEM`` is returned in the case of
+an out-of-memory error.
+
+The caller should lock exclusively against other modifiers of the array.
+
+
+5. Destroy an associative array, deleting all objects::
+
+    void assoc_array_destroy(struct assoc_array *array,
+                             const struct assoc_array_ops *ops);
+
+This destroys the contents of the associative array and leaves it
+completely empty.  It is not permitted for another thread to be traversing
+the array under the RCU read lock at the same time as this function is
+destroying it as no RCU deferral is performed on memory release -
+something that would require memory to be allocated.
+
+The caller should lock exclusively against other modifiers and accessors
+of the array.
+
+
+6. Garbage collect an associative array::
+
+    int assoc_array_gc(struct assoc_array *array,
+                       const struct assoc_array_ops *ops,
+                       bool (*iterator)(void *object, void *iterator_data),
+                       void *iterator_data);
+
+This iterates over the objects in an associative array and passes each one to
+``iterator()``.  If ``iterator()`` returns ``true``, the object is kept.  If it
+returns ``false``, the object will be freed.  If the ``iterator()`` function
+returns ``true``, it must perform any appropriate refcount incrementing on the
+object before returning.
+
+The internal tree will be packed down if possible as part of the iteration
+to reduce the number of nodes in it.
+
+The ``iterator_data`` is passed directly to ``iterator()`` and is otherwise
+ignored by the function.
+
+The function will return ``0`` if successful and ``-ENOMEM`` if there wasn't
+enough memory.
+
+It is possible for other threads to iterate over or search the array under
+the RCU read lock whilst this function is in progress.  The caller should
+lock exclusively against other modifiers of the array.
+
+
+Access Functions
+----------------
+
+There are two functions for accessing an associative array:
+
+1. Iterate over all the objects in an associative array::
+
+    int assoc_array_iterate(const struct assoc_array *array,
+                            int (*iterator)(const void *object,
+                                            void *iterator_data),
+                            void *iterator_data);
+
+This passes each object in the array to the iterator callback function.
+``iterator_data`` is private data for that function.
+
+This may be used on an array at the same time as the array is being
+modified, provided the RCU read lock is held.  Under such circumstances,
+it is possible for the iteration function to see some objects twice.  If
+this is a problem, then modification should be locked against.  The
+iteration algorithm should not, however, miss any objects.
+
+The function will return ``0`` if no objects were in the array or else it will
+return the result of the last iterator function called.  Iteration stops
+immediately if any call to the iteration function results in a non-zero
+return.
+
+
+2. Find an object in an associative array::
+
+    void *assoc_array_find(const struct assoc_array *array,
+                           const struct assoc_array_ops *ops,
+                           const void *index_key);
+
+This walks through the array's internal tree directly to the object
+specified by the index key..
+
+This may be used on an array at the same time as the array is being
+modified, provided the RCU read lock is held.
+
+The function will return the object if found (and set ``*_type`` to the object
+type) or will return ``NULL`` if the object was not found.
+
+
+Index Key Form
+--------------
+
+The index key can be of any form, but since the algorithms aren't told how long
+the key is, it is strongly recommended that the index key includes its length
+very early on before any variation due to the length would have an effect on
+comparisons.
+
+This will cause leaves with different length keys to scatter away from each
+other - and those with the same length keys to cluster together.
+
+It is also recommended that the index key begin with a hash of the rest of the
+key to maximise scattering throughout keyspace.
+
+The better the scattering, the wider and lower the internal tree will be.
+
+Poor scattering isn't too much of a problem as there are shortcuts and nodes
+can contain mixtures of leaves and metadata pointers.
+
+The index key is read in chunks of machine word.  Each chunk is subdivided into
+one nibble (4 bits) per level, so on a 32-bit CPU this is good for 8 levels and
+on a 64-bit CPU, 16 levels.  Unless the scattering is really poor, it is
+unlikely that more than one word of any particular index key will have to be
+used.
+
+
+Internal Workings
+=================
+
+The associative array data structure has an internal tree.  This tree is
+constructed of two types of metadata blocks: nodes and shortcuts.
+
+A node is an array of slots.  Each slot can contain one of four things:
+
+* A NULL pointer, indicating that the slot is empty.
+* A pointer to an object (a leaf).
+* A pointer to a node at the next level.
+* A pointer to a shortcut.
+
+
+Basic Internal Tree Layout
+--------------------------
+
+Ignoring shortcuts for the moment, the nodes form a multilevel tree.  The index
+key space is strictly subdivided by the nodes in the tree and nodes occur on
+fixed levels.  For example::
+
+ Level: 0               1               2               3
+        =============== =============== =============== ===============

+
+In the above example, there are 7 nodes (A-G), each with 16 slots (0-f).
+Assuming no other meta data nodes in the tree, the key space is divided
+thusly::
+
+    KEY PREFIX      NODE
+    ==========      ====
+    137*            D
+    138*            E

+    e6*             G
+    e[0-57-f]*      F
+    [02-df]*        A
+
+So, for instance, keys with the following example index keys will be found in
+the appropriate nodes::
+
+    INDEX KEY       PREFIX  NODE
+    =============== ======= ====
+    13694892892489  13      C

+
+To save memory, if a node can hold all the leaves in its portion of keyspace,
+then the node will have all those leaves in it and will not have any metadata
+pointers - even if some of those leaves would like to be in the same slot.
+
+A node can contain a heterogeneous mix of leaves and metadata pointers.
+Metadata pointers must be in the slots that match their subdivisions of key
+space.  The leaves can be in any slot not occupied by a metadata pointer.  It
+is guaranteed that none of the leaves in a node will match a slot occupied by a
+metadata pointer.  If the metadata pointer is there, any leaf whose key matches
+the metadata key prefix must be in the subtree that the metadata pointer points
+to.
+
+In the above example list of index keys, node A will contain::
+
+    SLOT    CONTENT         INDEX KEY (PREFIX)
+    ====    =============== ==================
+    1       PTR TO NODE B   1*

+
+
+Shortcuts
+---------
+
+Shortcuts are metadata records that jump over a piece of keyspace.  A shortcut
+is a replacement for a series of single-occupancy nodes ascending through the
+levels.  Shortcuts exist to save memory and to speed up traversal.
+
+It is possible for the root of the tree to be a shortcut - say, for example,
+the tree contains at least 17 nodes all with key prefix ``1111``.  The
+insertion algorithm will insert a shortcut to skip over the ``1111`` keyspace
+in a single bound and get to the fourth level where these actually become
+different.
+
+
+Splitting And Collapsing Nodes
+------------------------------
+
+Each node has a maximum capacity of 16 leaves and metadata pointers.  If the
+insertion algorithm finds that it is trying to insert a 17th object into a
+node, that node will be split such that at least two leaves that have a common
+key segment at that level end up in a separate node rooted on that slot for
+that common key segment.
+
+If the leaves in a full node and the leaf that is being inserted are
+sufficiently similar, then a shortcut will be inserted into the tree.
+
+When the number of objects in the subtree rooted at a node falls to 16 or
+fewer, then the subtree will be collapsed down to a single node - and this will
+ripple towards the root if possible.
+
+
+Non-Recursive Iteration
+-----------------------
+
+Each node and shortcut contains a back pointer to its parent and the number of
+slot in that parent that points to it.  None-recursive iteration uses these to
+proceed rootwards through the tree, going to the parent node, slot N + 1 to
+make sure progress is made without the need for a stack.
+
+The backpointers, however, make simultaneous alteration and iteration tricky.
+
+
+Simultaneous Alteration And Iteration
+-------------------------------------
+
+There are a number of cases to consider:
+
+1. Simple insert/replace.  This involves simply replacing a NULL or old
+   matching leaf pointer with the pointer to the new leaf after a barrier.
+   The metadata blocks don't change otherwise.  An old leaf won't be freed
+   until after the RCU grace period.
+
+2. Simple delete.  This involves just clearing an old matching leaf.  The
+   metadata blocks don't change otherwise.  The old leaf won't be freed until
+   after the RCU grace period.
+
+3. Insertion replacing part of a subtree that we haven't yet entered.  This
+   may involve replacement of part of that subtree - but that won't affect
+   the iteration as we won't have reached the pointer to it yet and the
+   ancestry blocks are not replaced (the layout of those does not change).
+
+4. Insertion replacing nodes that we're actively processing.  This isn't a
+   problem as we've passed the anchoring pointer and won't switch onto the
+   new layout until we follow the back pointers - at which point we've
+   already examined the leaves in the replaced node (we iterate over all the
+   leaves in a node before following any of its metadata pointers).
+
+   We might, however, re-see some leaves that have been split out into a new
+   branch that's in a slot further along than we were at.
+
+5. Insertion replacing nodes that we're processing a dependent branch of.
+   This won't affect us until we follow the back pointers.  Similar to (4).
+
+6. Deletion collapsing a branch under us.  This doesn't affect us because the
+   back pointers will get us back to the parent of the new node before we
+   could see the new node.  The entire collapsed subtree is thrown away
+   unchanged - and will still be rooted on the same slot, so we shouldn't
+   process it a second time as we'll go back to slot + 1.
+
+.. note::
+
+   Under some circumstances, we need to simultaneously change the parent
+   pointer and the parent slot pointer on a node (say, for example, we
+   inserted another node before it and moved it up a level).  We cannot do
+   this without locking against a read - so we have to replace that node too.
+
+   However, when we're changing a shortcut into a node this isn't a problem
+   as shortcuts only have one slot and so the parent slot number isn't used
+   when traversing backwards over one.  This means that it's okay to change
+   the slot number first - provided suitable barriers are used to make sure
+   the parent slot number is read after the back pointer.
+
+Obsolete blocks and leaves are freed up after an RCU grace period has passed,
+so as long as anyone doing walking or iteration holds the RCU read lock, the
+old superstructure should not go away on them.

+============================================
+The object-lifetime debugging infrastructure
+============================================
+
+:Author: Thomas Gleixner
+
+Introduction
+============
+
+debugobjects is a generic infrastructure to track the life time of
+kernel objects and validate the operations on those.
+
+debugobjects is useful to check for the following error patterns:
+
+-  Activation of uninitialized objects
+
+-  Initialization of active objects
+
+-  Usage of freed/destroyed objects
+
+debugobjects is not changing the data structure of the real object so it
+can be compiled in with a minimal runtime impact and enabled on demand
+with a kernel command line option.
+
+Howto use debugobjects
+======================
+
+A kernel subsystem needs to provide a data structure which describes the
+object type and add calls into the debug code at appropriate places. The
+data structure to describe the object type needs at minimum the name of
+the object type. Optional functions can and should be provided to fixup
+detected problems so the kernel can continue to work and the debug
+information can be retrieved from a live system instead of hard core
+debugging with serial consoles and stack trace transcripts from the
+monitor.
+
+The debug calls provided by debugobjects are:
+
+-  debug_object_init
+
+-  debug_object_init_on_stack
+
+-  debug_object_activate
+
+-  debug_object_deactivate
+
+-  debug_object_destroy
+
+-  debug_object_free
+
+-  debug_object_assert_init
+
+Each of these functions takes the address of the real object and a
+pointer to the object type specific debug description structure.
+
+Each detected error is reported in the statistics and a limited number
+of errors are printk'ed including a full stack trace.
+
+The statistics are available via /sys/kernel/debug/debug_objects/stats.
+They provide information about the number of warnings and the number of
+successful fixups along with information about the usage of the internal
+tracking objects and the state of the internal tracking objects pool.
+
+Debug functions
+===============
+
+.. kernel-doc:: lib/debugobjects.c
+   :functions: debug_object_init
+
+This function is called whenever the initialization function of a real
+object is called.
+
+When the real object is already tracked by debugobjects it is checked,
+whether the object can be initialized. Initializing is not allowed for
+active and destroyed objects. When debugobjects detects an error, then
+it calls the fixup_init function of the object type description
+structure if provided by the caller. The fixup function can correct the
+problem before the real initialization of the object happens. E.g. it
+can deactivate an active object in order to prevent damage to the
+subsystem.
+
+When the real object is not yet tracked by debugobjects, debugobjects
+allocates a tracker object for the real object and sets the tracker
+object state to ODEBUG_STATE_INIT. It verifies that the object is not
+on the callers stack. If it is on the callers stack then a limited
+number of warnings including a full stack trace is printk'ed. The
+calling code must use debug_object_init_on_stack() and remove the
+object before leaving the function which allocated it. See next section.
+
+.. kernel-doc:: lib/debugobjects.c
+   :functions: debug_object_init_on_stack
+
+This function is called whenever the initialization function of a real
+object which resides on the stack is called.
+
+When the real object is already tracked by debugobjects it is checked,
+whether the object can be initialized. Initializing is not allowed for
+active and destroyed objects. When debugobjects detects an error, then
+it calls the fixup_init function of the object type description
+structure if provided by the caller. The fixup function can correct the
+problem before the real initialization of the object happens. E.g. it
+can deactivate an active object in order to prevent damage to the
+subsystem.
+
+When the real object is not yet tracked by debugobjects debugobjects
+allocates a tracker object for the real object and sets the tracker
+object state to ODEBUG_STATE_INIT. It verifies that the object is on
+the callers stack.
+
+An object which is on the stack must be removed from the tracker by
+calling debug_object_free() before the function which allocates the
+object returns. Otherwise we keep track of stale objects.
+
+.. kernel-doc:: lib/debugobjects.c
+   :functions: debug_object_activate
+
+This function is called whenever the activation function of a real
+object is called.
+
+When the real object is already tracked by debugobjects it is checked,
+whether the object can be activated. Activating is not allowed for
+active and destroyed objects. When debugobjects detects an error, then
+it calls the fixup_activate function of the object type description
+structure if provided by the caller. The fixup function can correct the
+problem before the real activation of the object happens. E.g. it can
+deactivate an active object in order to prevent damage to the subsystem.
+
+When the real object is not yet tracked by debugobjects then the
+fixup_activate function is called if available. This is necessary to
+allow the legitimate activation of statically allocated and initialized
+objects. The fixup function checks whether the object is valid and calls
+the debug_objects_init() function to initialize the tracking of this
+object.
+
+When the activation is legitimate, then the state of the associated
+tracker object is set to ODEBUG_STATE_ACTIVE.
+
+
+.. kernel-doc:: lib/debugobjects.c
+   :functions: debug_object_deactivate
+
+This function is called whenever the deactivation function of a real
+object is called.
+
+When the real object is tracked by debugobjects it is checked, whether
+the object can be deactivated. Deactivating is not allowed for untracked
+or destroyed objects.
+
+When the deactivation is legitimate, then the state of the associated
+tracker object is set to ODEBUG_STATE_INACTIVE.
+
+.. kernel-doc:: lib/debugobjects.c
+   :functions: debug_object_destroy
+
+This function is called to mark an object destroyed. This is useful to
+prevent the usage of invalid objects, which are still available in
+memory: either statically allocated objects or objects which are freed
+later.
+
+When the real object is tracked by debugobjects it is checked, whether
+the object can be destroyed. Destruction is not allowed for active and
+destroyed objects. When debugobjects detects an error, then it calls the
+fixup_destroy function of the object type description structure if
+provided by the caller. The fixup function can correct the problem
+before the real destruction of the object happens. E.g. it can
+deactivate an active object in order to prevent damage to the subsystem.
+
+When the destruction is legitimate, then the state of the associated
+tracker object is set to ODEBUG_STATE_DESTROYED.
+
+.. kernel-doc:: lib/debugobjects.c
+   :functions: debug_object_free
+
+This function is called before an object is freed.
+
+When the real object is tracked by debugobjects it is checked, whether
+the object can be freed. Free is not allowed for active objects. When
+debugobjects detects an error, then it calls the fixup_free function of
+the object type description structure if provided by the caller. The
+fixup function can correct the problem before the real free of the
+object happens. E.g. it can deactivate an active object in order to
+prevent damage to the subsystem.
+
+Note that debug_object_free removes the object from the tracker. Later
+usage of the object is detected by the other debug checks.
+
+
+.. kernel-doc:: lib/debugobjects.c
+   :functions: debug_object_assert_init
+
+This function is called to assert that an object has been initialized.
+
+When the real object is not tracked by debugobjects, it calls
+fixup_assert_init of the object type description structure provided by
+the caller, with the hardcoded object state ODEBUG_NOT_AVAILABLE. The
+fixup function can correct the problem by calling debug_object_init
+and other specific initializing functions.
+
+When the real object is already tracked by debugobjects it is ignored.
+
+Fixup functions
+===============
+
+Debug object type description structure
+---------------------------------------
+
+.. kernel-doc:: include/linux/debugobjects.h
+   :internal:
+
+fixup_init
+-----------
+
+This function is called from the debug code whenever a problem in
+debug_object_init is detected. The function takes the address of the
+object and the state which is currently recorded in the tracker.
+
+Called from debug_object_init when the object state is:
+
+-  ODEBUG_STATE_ACTIVE
+
+The function returns true when the fixup was successful, otherwise
+false. The return value is used to update the statistics.
+
+Note, that the function needs to call the debug_object_init() function
+again, after the damage has been repaired in order to keep the state
+consistent.
+
+fixup_activate
+---------------
+
+This function is called from the debug code whenever a problem in
+debug_object_activate is detected.
+
+Called from debug_object_activate when the object state is:
+
+-  ODEBUG_STATE_NOTAVAILABLE
+
+-  ODEBUG_STATE_ACTIVE
+
+The function returns true when the fixup was successful, otherwise
+false. The return value is used to update the statistics.
+
+Note that the function needs to call the debug_object_activate()
+function again after the damage has been repaired in order to keep the
+state consistent.
+
+The activation of statically initialized objects is a special case. When
+debug_object_activate() has no tracked object for this object address
+then fixup_activate() is called with object state
+ODEBUG_STATE_NOTAVAILABLE. The fixup function needs to check whether
+this is a legitimate case of a statically initialized object or not. In
+case it is it calls debug_object_init() and debug_object_activate()
+to make the object known to the tracker and marked active. In this case
+the function should return false because this is not a real fixup.
+
+fixup_destroy
+--------------
+
+This function is called from the debug code whenever a problem in
+debug_object_destroy is detected.
+
+Called from debug_object_destroy when the object state is:
+
+-  ODEBUG_STATE_ACTIVE
+
+The function returns true when the fixup was successful, otherwise
+false. The return value is used to update the statistics.
+
+fixup_free
+-----------
+
+This function is called from the debug code whenever a problem in
+debug_object_free is detected. Further it can be called from the debug
+checks in kfree/vfree, when an active object is detected from the
+debug_check_no_obj_freed() sanity checks.
+
+Called from debug_object_free() or debug_check_no_obj_freed() when
+the object state is:
+
+-  ODEBUG_STATE_ACTIVE
+
+The function returns true when the fixup was successful, otherwise
+false. The return value is used to update the statistics.
+
+fixup_assert_init
+-------------------
+
+This function is called from the debug code whenever a problem in
+debug_object_assert_init is detected.
+
+Called from debug_object_assert_init() with a hardcoded state
+ODEBUG_STATE_NOTAVAILABLE when the object is not found in the debug
+bucket.
+
+The function returns true when the fixup was successful, otherwise
+false. The return value is used to update the statistics.
+
+Note, this function should make sure debug_object_init() is called
+before returning.
+
+The handling of statically initialized objects is a special case. The
+fixup function should check if this is a legitimate case of a statically
+initialized object or not. In this case only debug_object_init()
+should be called to make the object known to the tracker. Then the
+function should return false because this is not a real fixup.

+=================================================
+Semantics and Behavior of Local Atomic Operations
+=================================================
+
+:Author: Mathieu Desnoyers
+
+
+This document explains the purpose of the local atomic operations, how
+to implement them for any given architecture and shows how they can be used
+properly. It also stresses on the precautions that must be taken when reading
+those local variables across CPUs when the order of memory writes matters.
+
+.. note::
+
+    Note that ``local_t`` based operations are not recommended for general
+    kernel use. Please use the ``this_cpu`` operations instead unless there is
+    really a special purpose. Most uses of ``local_t`` in the kernel have been
+    replaced by ``this_cpu`` operations. ``this_cpu`` operations combine the
+    relocation with the ``local_t`` like semantics in a single instruction and
+    yield more compact and faster executing code.
+
+
+Purpose of local atomic operations
+==================================
+
+Local atomic operations are meant to provide fast and highly reentrant per CPU
+counters. They minimize the performance cost of standard atomic operations by
+removing the LOCK prefix and memory barriers normally required to synchronize
+across CPUs.
+
+Having fast per CPU atomic counters is interesting in many cases: it does not
+require disabling interrupts to protect from interrupt handlers and it permits
+coherent counters in NMI handlers. It is especially useful for tracing purposes
+and for various performance monitoring counters.
+
+Local atomic operations only guarantee variable modification atomicity wrt the
+CPU which owns the data. Therefore, care must taken to make sure that only one
+CPU writes to the ``local_t`` data. This is done by using per cpu data and
+making sure that we modify it from within a preemption safe context. It is
+however permitted to read ``local_t`` data from any CPU: it will then appear to
+be written out of order wrt other memory writes by the owner CPU.
+
+
+Implementation for a given architecture
+=======================================
+
+It can be done by slightly modifying the standard atomic operations: only
+their UP variant must be kept. It typically means removing LOCK prefix (on
+i386 and x86_64) and any SMP synchronization barrier. If the architecture does
+not have a different behavior between SMP and UP, including
+``asm-generic/local.h`` in your architecture's ``local.h`` is sufficient.
+
+The ``local_t`` type is defined as an opaque ``signed long`` by embedding an
+``atomic_long_t`` inside a structure. This is made so a cast from this type to
+a ``long`` fails. The definition looks like::
+
+    typedef struct { atomic_long_t a; } local_t;
+
+
+Rules to follow when using local atomic operations
+==================================================
+
+* Variables touched by local ops must be per cpu variables.
+* *Only* the CPU owner of these variables must write to them.
+* This CPU can use local ops from any context (process, irq, softirq, nmi, ...)
+  to update its ``local_t`` variables.
+* Preemption (or interrupts) must be disabled when using local ops in
+  process context to make sure the process won't be migrated to a
+  different CPU between getting the per-cpu variable and doing the
+  actual local op.
+* When using local ops in interrupt context, no special care must be
+  taken on a mainline kernel, since they will run on the local CPU with
+  preemption already disabled. I suggest, however, to explicitly
+  disable preemption anyway to make sure it will still work correctly on
+  -rt kernels.
+* Reading the local cpu variable will provide the current copy of the
+  variable.
+* Reads of these variables can be done from any CPU, because updates to
+  "``long``", aligned, variables are always atomic. Since no memory
+  synchronization is done by the writer CPU, an outdated copy of the
+  variable can be read when reading some *other* cpu's variables.
+
+
+How to use local atomic operations
+==================================
+
+::
+
+    #include <linux/percpu.h>
+    #include <asm/local.h>
+
+    static DEFINE_PER_CPU(local_t, counters) = LOCAL_INIT(0);
+
+
+Counting
+========
+
+Counting is done on all the bits of a signed long.
+
+In preemptible context, use ``get_cpu_var()`` and ``put_cpu_var()`` around
+local atomic operations: it makes sure that preemption is disabled around write
+access to the per cpu variable. For instance::
+
+    local_inc(&get_cpu_var(counters));
+    put_cpu_var(counters);
+
+If you are already in a preemption-safe context, you can use
+``this_cpu_ptr()`` instead::
+
+    local_inc(this_cpu_ptr(&counters));
+
+
+
+Reading the counters
+====================
+
+Those local counters can be read from foreign CPUs to sum the count. Note that
+the data seen by local_read across CPUs must be considered to be out of order
+relatively to other memory writes happening on the CPU that owns the data::
+
+    long sum = 0;
+    for_each_online_cpu(cpu)
+            sum += local_read(&per_cpu(counters, cpu));
+
+If you want to use a remote local_read to synchronize access to a resource
+between CPUs, explicit ``smp_wmb()`` and ``smp_rmb()`` memory barriers must be used
+respectively on the writer and the reader CPUs. It would be the case if you use
+the ``local_t`` variable as a counter of bytes written in a buffer: there should
+be a ``smp_wmb()`` between the buffer write and the counter increment and also a
+``smp_rmb()`` between the counter read and the buffer read.
+
+
+Here is a sample module which implements a basic per cpu counter using
+``local.h``::
+
+    /* test-local.c
+     *
+     * Sample module for local.h usage.

+===============================
+The Linux Kernel Tracepoint API
+===============================

+
+Introduction
+============
+
+Tracepoints are static probe points that are located in strategic points
+throughout the kernel. 'Probes' register/unregister with tracepoints via
+a callback mechanism. The 'probes' are strictly typed functions that are
+passed a unique set of parameters defined by each tracepoint.
+
+From this simple callback mechanism, 'probes' can be used to profile,
+debug, and understand kernel behavior. There are a number of tools that
+provide a framework for using 'probes'. These tools include Systemtap,
+ftrace, and LTTng.
+
+Tracepoints are defined in a number of header files via various macros.
+Thus, the purpose of this document is to provide a clear accounting of
+the available tracepoints. The intention is to understand not only what
+tracepoints are available but also to understand where future
+tracepoints might be added.
+
+The API presented has functions of the form:
+``trace_tracepointname(function parameters)``. These are the tracepoints
+callbacks that are found throughout the code. Registering and
+unregistering probes with these callback sites is covered in the
+``Documentation/trace/*`` directory.

-@flags:
-
-  WQ_UNBOUND
-
-	Work items queued to an unbound wq are served by the special
-	worker-pools which host workers which are not bound to any
-	specific CPU.  This makes the wq behave as a simple execution
-	context provider without concurrency management.  The unbound
-	worker-pools try to start execution of work items as soon as
-	possible.  Unbound wq sacrifices locality but is useful for
-	the following cases.
-
-	* Wide fluctuation in the concurrency level requirement is
-	  expected and using bound wq may end up creating large number
-	  of mostly unused workers across different CPUs as the issuer
-	  hops through different CPUs.
-
-	* Long running CPU intensive workloads which can be better
-	  managed by the system scheduler.
-
-  WQ_FREEZABLE
-
-	A freezable wq participates in the freeze phase of the system
-	suspend operations.  Work items on the wq are drained and no
-	new work item starts execution until thawed.
-
-  WQ_MEM_RECLAIM
-
-	All wq which might be used in the memory reclaim paths _MUST_
-	have this flag set.  The wq is guaranteed to have at least one
-	execution context regardless of memory pressure.
-
-  WQ_HIGHPRI
 
-	Work items of a highpri wq are queued to the highpri
-	worker-pool of the target cpu.  Highpri worker-pools are
-	served by worker threads with elevated nice level.
-
-	Note that normal and highpri worker-pools don't interact with
-	each other.  Each maintain its separate pool of workers and
-	implements concurrency management among its workers.
-
-  WQ_CPU_INTENSIVE
-
-	Work items of a CPU intensive wq do not contribute to the
-	concurrency level.  In other words, runnable CPU intensive
-	work items will not prevent other work items in the same
-	worker-pool from starting execution.  This is useful for bound
-	work items which are expected to hog CPU cycles so that their
-	execution is regulated by the system scheduler.
-
-	Although CPU intensive work items don't contribute to the
-	concurrency level, start of their executions is still
-	regulated by the concurrency management and runnable
-	non-CPU-intensive work items can delay execution of CPU
-	intensive work items.

-	This flag is meaningless for unbound wq.

-Note that the flag WQ_NON_REENTRANT no longer exists as all workqueues

 executing at the same time per CPU.

+Programming Interface
+=====================
+
+Please note that the kernel crypto API contains the AEAD givcrypt API
+(crypto_aead_giv\* and aead_givcrypt\* function calls in
+include/crypto/aead.h). This API is obsolete and will be removed in the
+future. To obtain the functionality of an AEAD cipher with internal IV
+generation, use the IV generator as a regular cipher. For example,
+rfc4106(gcm(aes)) is the AEAD cipher with external IV generation and
+seqniv(rfc4106(gcm(aes))) implies that the kernel crypto API generates
+the IV. Different IV generators are available.

+Kernel Crypto API Architecture
+==============================
+
+Cipher algorithm types
+----------------------
+
+The kernel crypto API provides different API calls for the following
+cipher types:
+
+-  Symmetric ciphers
+
+-  AEAD ciphers
+
+-  Message digest, including keyed message digest
+
+-  Random number generation
+
+-  User space interface
+
+Ciphers And Templates
+---------------------
+
+The kernel crypto API provides implementations of single block ciphers
+and message digests. In addition, the kernel crypto API provides
+numerous "templates" that can be used in conjunction with the single
+block ciphers and message digests. Templates include all types of block
+chaining mode, the HMAC mechanism, etc.
+
+Single block ciphers and message digests can either be directly used by
+a caller or invoked together with a template to form multi-block ciphers
+or keyed message digests.
+
+A single block cipher may even be called with multiple templates.
+However, templates cannot be used without a single cipher.
+
+See /proc/crypto and search for "name". For example:
+
+-  aes
+
+-  ecb(aes)
+
+-  cmac(aes)
+
+-  ccm(aes)
+
+-  rfc4106(gcm(aes))
+
+-  sha1
+
+-  hmac(sha1)
+
+-  authenc(hmac(sha1),cbc(aes))
+
+In these examples, "aes" and "sha1" are the ciphers and all others are
+the templates.
+
+Synchronous And Asynchronous Operation
+--------------------------------------
+
+The kernel crypto API provides synchronous and asynchronous API
+operations.
+
+When using the synchronous API operation, the caller invokes a cipher
+operation which is performed synchronously by the kernel crypto API.
+That means, the caller waits until the cipher operation completes.
+Therefore, the kernel crypto API calls work like regular function calls.
+For synchronous operation, the set of API calls is small and
+conceptually similar to any other crypto library.
+
+Asynchronous operation is provided by the kernel crypto API which
+implies that the invocation of a cipher operation will complete almost
+instantly. That invocation triggers the cipher operation but it does not
+signal its completion. Before invoking a cipher operation, the caller
+must provide a callback function the kernel crypto API can invoke to
+signal the completion of the cipher operation. Furthermore, the caller
+must ensure it can handle such asynchronous events by applying
+appropriate locking around its data. The kernel crypto API does not
+perform any special serialization operation to protect the caller's data
+integrity.
+
+Crypto API Cipher References And Priority
+-----------------------------------------
+
+A cipher is referenced by the caller with a string. That string has the
+following semantics:
+
+::
+
+        template(single block cipher)
+
+
+where "template" and "single block cipher" is the aforementioned
+template and single block cipher, respectively. If applicable,
+additional templates may enclose other templates, such as
+
+::
+
+        template1(template2(single block cipher)))
+
+
+The kernel crypto API may provide multiple implementations of a template
+or a single block cipher. For example, AES on newer Intel hardware has
+the following implementations: AES-NI, assembler implementation, or
+straight C. Now, when using the string "aes" with the kernel crypto API,
+which cipher implementation is used? The answer to that question is the
+priority number assigned to each cipher implementation by the kernel
+crypto API. When a caller uses the string to refer to a cipher during
+initialization of a cipher handle, the kernel crypto API looks up all
+implementations providing an implementation with that name and selects
+the implementation with the highest priority.
+
+Now, a caller may have the need to refer to a specific cipher
+implementation and thus does not want to rely on the priority-based
+selection. To accommodate this scenario, the kernel crypto API allows
+the cipher implementation to register a unique name in addition to
+common names. When using that unique name, a caller is therefore always
+sure to refer to the intended cipher implementation.
+
+The list of available ciphers is given in /proc/crypto. However, that
+list does not specify all possible permutations of templates and
+ciphers. Each block listed in /proc/crypto may contain the following
+information -- if one of the components listed as follows are not
+applicable to a cipher, it is not displayed:
+
+-  name: the generic name of the cipher that is subject to the
+   priority-based selection -- this name can be used by the cipher
+   allocation API calls (all names listed above are examples for such
+   generic names)
+
+-  driver: the unique name of the cipher -- this name can be used by the
+   cipher allocation API calls
+
+-  module: the kernel module providing the cipher implementation (or
+   "kernel" for statically linked ciphers)
+
+-  priority: the priority value of the cipher implementation
+
+-  refcnt: the reference count of the respective cipher (i.e. the number
+   of current consumers of this cipher)
+
+-  selftest: specification whether the self test for the cipher passed
+
+-  type:
+
+   -  skcipher for symmetric key ciphers
+
+   -  cipher for single block ciphers that may be used with an
+      additional template
+
+   -  shash for synchronous message digest
+
+   -  ahash for asynchronous message digest
+
+   -  aead for AEAD cipher type
+
+   -  compression for compression type transformations
+
+   -  rng for random number generator
+
+   -  givcipher for cipher with associated IV generator (see the geniv
+      entry below for the specification of the IV generator type used by
+      the cipher implementation)
+
+   -  kpp for a Key-agreement Protocol Primitive (KPP) cipher such as
+      an ECDH or DH implementation
+
+-  blocksize: blocksize of cipher in bytes
+
+-  keysize: key size in bytes
+
+-  ivsize: IV size in bytes
+
+-  seedsize: required size of seed data for random number generator
+
+-  digestsize: output size of the message digest
+
+-  geniv: IV generation type:
+
+   -  eseqiv for encrypted sequence number based IV generation
+
+   -  seqiv for sequence number based IV generation
+
+   -  chainiv for chain iv generation
+
+   -  <builtin> is a marker that the cipher implements IV generation and
+      handling as it is specific to the given cipher
+
+Key Sizes
+---------
+
+When allocating a cipher handle, the caller only specifies the cipher
+type. Symmetric ciphers, however, typically support multiple key sizes
+(e.g. AES-128 vs. AES-192 vs. AES-256). These key sizes are determined
+with the length of the provided key. Thus, the kernel crypto API does
+not provide a separate way to select the particular symmetric cipher key
+size.
+
+Cipher Allocation Type And Masks
+--------------------------------
+
+The different cipher handle allocation functions allow the specification
+of a type and mask flag. Both parameters have the following meaning (and
+are therefore not covered in the subsequent sections).
+
+The type flag specifies the type of the cipher algorithm. The caller
+usually provides a 0 when the caller wants the default handling.
+Otherwise, the caller may provide the following selections which match
+the aforementioned cipher types:
+
+-  CRYPTO_ALG_TYPE_CIPHER Single block cipher
+
+-  CRYPTO_ALG_TYPE_COMPRESS Compression
+
+-  CRYPTO_ALG_TYPE_AEAD Authenticated Encryption with Associated Data
+   (MAC)
+
+-  CRYPTO_ALG_TYPE_BLKCIPHER Synchronous multi-block cipher
+
+-  CRYPTO_ALG_TYPE_ABLKCIPHER Asynchronous multi-block cipher
+
+-  CRYPTO_ALG_TYPE_GIVCIPHER Asynchronous multi-block cipher packed
+   together with an IV generator (see geniv field in the /proc/crypto
+   listing for the known IV generators)
+
+-  CRYPTO_ALG_TYPE_KPP Key-agreement Protocol Primitive (KPP) such as
+   an ECDH or DH implementation
+
+-  CRYPTO_ALG_TYPE_DIGEST Raw message digest
+
+-  CRYPTO_ALG_TYPE_HASH Alias for CRYPTO_ALG_TYPE_DIGEST
+
+-  CRYPTO_ALG_TYPE_SHASH Synchronous multi-block hash
+
+-  CRYPTO_ALG_TYPE_AHASH Asynchronous multi-block hash
+
+-  CRYPTO_ALG_TYPE_RNG Random Number Generation
+
+-  CRYPTO_ALG_TYPE_AKCIPHER Asymmetric cipher
+
+-  CRYPTO_ALG_TYPE_PCOMPRESS Enhanced version of
+   CRYPTO_ALG_TYPE_COMPRESS allowing for segmented compression /
+   decompression instead of performing the operation on one segment
+   only. CRYPTO_ALG_TYPE_PCOMPRESS is intended to replace
+   CRYPTO_ALG_TYPE_COMPRESS once existing consumers are converted.
+
+The mask flag restricts the type of cipher. The only allowed flag is
+CRYPTO_ALG_ASYNC to restrict the cipher lookup function to
+asynchronous ciphers. Usually, a caller provides a 0 for the mask flag.
+
+When the caller provides a mask and type specification, the caller
+limits the search the kernel crypto API can perform for a suitable
+cipher implementation for the given cipher name. That means, even when a
+caller uses a cipher name that exists during its initialization call,
+the kernel crypto API may not select it due to the used type and mask
+field.
+
+Internal Structure of Kernel Crypto API
+---------------------------------------
+
+The kernel crypto API has an internal structure where a cipher
+implementation may use many layers and indirections. This section shall
+help to clarify how the kernel crypto API uses various components to
+implement the complete cipher.
+
+The following subsections explain the internal structure based on
+existing cipher implementations. The first section addresses the most
+complex scenario where all other scenarios form a logical subset.
+
+Generic AEAD Cipher Structure
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following ASCII art decomposes the kernel crypto API layers when
+using the AEAD cipher with the automated IV generation. The shown
+example is used by the IPSEC layer.
+
+For other use cases of AEAD ciphers, the ASCII art applies as well, but
+the caller may not use the AEAD cipher with a separate IV generator. In
+this case, the caller must generate the IV.
+
+The depicted example decomposes the AEAD cipher of GCM(AES) based on the
+generic C implementations (gcm.c, aes-generic.c, ctr.c, ghash-generic.c,
+seqiv.c). The generic implementation serves as an example showing the
+complete logic of the kernel crypto API.
+
+It is possible that some streamlined cipher implementations (like
+AES-NI) provide implementations merging aspects which in the view of the
+kernel crypto API cannot be decomposed into layers any more. In case of
+the AES-NI implementation, the CTR mode, the GHASH implementation and
+the AES cipher are all merged into one cipher implementation registered
+with the kernel crypto API. In this case, the concept described by the
+following ASCII art applies too. However, the decomposition of GCM into
+the individual sub-components by the kernel crypto API is not done any
+more.
+
+Each block in the following ASCII art is an independent cipher instance
+obtained from the kernel crypto API. Each block is accessed by the
+caller or by other blocks using the API functions defined by the kernel
+crypto API for the cipher implementation type.
+
+The blocks below indicate the cipher type as well as the specific logic
+implemented in the cipher.
+
+The ASCII art picture also indicates the call structure, i.e. who calls
+which component. The arrows point to the invoked block where the caller
+uses the API applicable to the cipher type specified for the block.
+
+::
+
+
+    kernel crypto API                                |   IPSEC Layer
+                                                     |

+                     | (2)
+    +-----------+    |
+    |           | <--+                (2)
+    |   aead    | <-----------------------------------  esp_input
+    |   (gcm)   | ------------+
+    +-----------+             |
+          | (3)               | (5)
+          v                   v
+    +-----------+       +-----------+
+    |           |       |           |
+    |  skcipher |       |   ahash   |
+    |   (ctr)   | ---+  |  (ghash)  |
+    +-----------+    |  +-----------+
+                     |
+    +-----------+    | (4)
+    |           | <--+
+    |   cipher  |
+    |   (aes)   |
+    +-----------+
+
+
+
+The following call sequence is applicable when the IPSEC layer triggers
+an encryption operation with the esp_output function. During
+configuration, the administrator set up the use of rfc4106(gcm(aes)) as
+the cipher for ESP. The following call sequence is now depicted in the
+ASCII art above:
+
+1. esp_output() invokes crypto_aead_encrypt() to trigger an
+   encryption operation of the AEAD cipher with IV generator.
+
+   In case of GCM, the SEQIV implementation is registered as GIVCIPHER
+   in crypto_rfc4106_alloc().
+
+   The SEQIV performs its operation to generate an IV where the core
+   function is seqiv_geniv().
+
+2. Now, SEQIV uses the AEAD API function calls to invoke the associated
+   AEAD cipher. In our case, during the instantiation of SEQIV, the
+   cipher handle for GCM is provided to SEQIV. This means that SEQIV
+   invokes AEAD cipher operations with the GCM cipher handle.
+
+   During instantiation of the GCM handle, the CTR(AES) and GHASH
+   ciphers are instantiated. The cipher handles for CTR(AES) and GHASH
+   are retained for later use.
+
+   The GCM implementation is responsible to invoke the CTR mode AES and
+   the GHASH cipher in the right manner to implement the GCM
+   specification.
+
+3. The GCM AEAD cipher type implementation now invokes the SKCIPHER API
+   with the instantiated CTR(AES) cipher handle.
+
+   During instantiation of the CTR(AES) cipher, the CIPHER type
+   implementation of AES is instantiated. The cipher handle for AES is
+   retained.
+
+   That means that the SKCIPHER implementation of CTR(AES) only
+   implements the CTR block chaining mode. After performing the block
+   chaining operation, the CIPHER implementation of AES is invoked.
+
+4. The SKCIPHER of CTR(AES) now invokes the CIPHER API with the AES
+   cipher handle to encrypt one block.
+
+5. The GCM AEAD implementation also invokes the GHASH cipher
+   implementation via the AHASH API.
+
+When the IPSEC layer triggers the esp_input() function, the same call
+sequence is followed with the only difference that the operation starts
+with step (2).
+
+Generic Block Cipher Structure
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Generic block ciphers follow the same concept as depicted with the ASCII
+art picture above.
+
+For example, CBC(AES) is implemented with cbc.c, and aes-generic.c. The
+ASCII art picture above applies as well with the difference that only
+step (4) is used and the SKCIPHER block chaining mode is CBC.
+
+Generic Keyed Message Digest Structure
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Keyed message digest implementations again follow the same concept as
+depicted in the ASCII art picture above.
+
+For example, HMAC(SHA256) is implemented with hmac.c and
+sha256_generic.c. The following ASCII art illustrates the
+implementation:
+
+::
+
+
+    kernel crypto API            |       Caller
+                                 |
+    +-----------+         (1)    |
+    |           | <------------------  some_function
+    |   ahash   |
+    |   (hmac)  | ---+
+    +-----------+    |
+                     | (2)
+    +-----------+    |
+    |           | <--+
+    |   shash   |
+    |  (sha256) |
+    +-----------+
+
+
+
+The following call sequence is applicable when a caller triggers an HMAC
+operation:
+
+1. The AHASH API functions are invoked by the caller. The HMAC
+   implementation performs its operation as needed.
+
+   During initialization of the HMAC cipher, the SHASH cipher type of
+   SHA256 is instantiated. The cipher handle for the SHA256 instance is
+   retained.
+
+   At one time, the HMAC implementation requires a SHA256 operation
+   where the SHA256 cipher handle is used.
+
+2. The HMAC instance now invokes the SHASH API with the SHA256 cipher
+   handle to calculate the message digest.

+Developing Cipher Algorithms
+============================
+
+Registering And Unregistering Transformation
+--------------------------------------------
+
+There are three distinct types of registration functions in the Crypto
+API. One is used to register a generic cryptographic transformation,
+while the other two are specific to HASH transformations and
+COMPRESSion. We will discuss the latter two in a separate chapter, here
+we will only look at the generic ones.
+
+Before discussing the register functions, the data structure to be
+filled with each, struct crypto_alg, must be considered -- see below
+for a description of this data structure.
+
+The generic registration functions can be found in
+include/linux/crypto.h and their definition can be seen below. The
+former function registers a single transformation, while the latter
+works on an array of transformation descriptions. The latter is useful
+when registering transformations in bulk, for example when a driver
+implements multiple transformations.
+
+::
+
+       int crypto_register_alg(struct crypto_alg *alg);
+       int crypto_register_algs(struct crypto_alg *algs, int count);
+
+
+The counterparts to those functions are listed below.
+
+::
+
+       int crypto_unregister_alg(struct crypto_alg *alg);
+       int crypto_unregister_algs(struct crypto_alg *algs, int count);
+
+
+Notice that both registration and unregistration functions do return a
+value, so make sure to handle errors. A return code of zero implies
+success. Any return code < 0 implies an error.
+
+The bulk registration/unregistration functions register/unregister each
+transformation in the given array of length count. They handle errors as
+follows:
+
+-  crypto_register_algs() succeeds if and only if it successfully
+   registers all the given transformations. If an error occurs partway
+   through, then it rolls back successful registrations before returning
+   the error code. Note that if a driver needs to handle registration
+   errors for individual transformations, then it will need to use the
+   non-bulk function crypto_register_alg() instead.
+
+-  crypto_unregister_algs() tries to unregister all the given
+   transformations, continuing on error. It logs errors and always
+   returns zero.
+
+Single-Block Symmetric Ciphers [CIPHER]
+---------------------------------------
+
+Example of transformations: aes, arc4, ...
+
+This section describes the simplest of all transformation
+implementations, that being the CIPHER type used for symmetric ciphers.
+The CIPHER type is used for transformations which operate on exactly one
+block at a time and there are no dependencies between blocks at all.
+
+Registration specifics
+~~~~~~~~~~~~~~~~~~~~~~
+
+The registration of [CIPHER] algorithm is specific in that struct
+crypto_alg field .cra_type is empty. The .cra_u.cipher has to be
+filled in with proper callbacks to implement this transformation.
+
+See struct cipher_alg below.
+
+Cipher Definition With struct cipher_alg
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Struct cipher_alg defines a single block cipher.
+
+Here are schematics of how these functions are called when operated from
+other part of the kernel. Note that the .cia_setkey() call might happen
+before or after any of these schematics happen, but must not happen
+during any of these are in-flight.
+
+::
+
+             KEY ---.    PLAINTEXT ---.
+                    v                 v
+              .cia_setkey() -> .cia_encrypt()
+                                      |
+                                      '-----> CIPHERTEXT
+
+
+Please note that a pattern where .cia_setkey() is called multiple times
+is also valid:
+
+::
+
+
+      KEY1 --.    PLAINTEXT1 --.         KEY2 --.    PLAINTEXT2 --.
+             v                 v                v                 v
+       .cia_setkey() -> .cia_encrypt() -> .cia_setkey() -> .cia_encrypt()
+                               |                                  |
+                               '---> CIPHERTEXT1                  '---> CIPHERTEXT2
+
+
+Multi-Block Ciphers
+-------------------
+
+Example of transformations: cbc(aes), ecb(arc4), ...
+
+This section describes the multi-block cipher transformation
+implementations. The multi-block ciphers are used for transformations
+which operate on scatterlists of data supplied to the transformation
+functions. They output the result into a scatterlist of data as well.
+
+Registration Specifics
+~~~~~~~~~~~~~~~~~~~~~~
+
+The registration of multi-block cipher algorithms is one of the most
+standard procedures throughout the crypto API.
+
+Note, if a cipher implementation requires a proper alignment of data,
+the caller should use the functions of crypto_skcipher_alignmask() to
+identify a memory alignment mask. The kernel crypto API is able to
+process requests that are unaligned. This implies, however, additional
+overhead as the kernel crypto API needs to perform the realignment of
+the data which may imply moving of data.
+
+Cipher Definition With struct blkcipher_alg and ablkcipher_alg
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Struct blkcipher_alg defines a synchronous block cipher whereas struct
+ablkcipher_alg defines an asynchronous block cipher.
+
+Please refer to the single block cipher description for schematics of
+the block cipher usage.
+
+Specifics Of Asynchronous Multi-Block Cipher
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are a couple of specifics to the asynchronous interface.
+
+First of all, some of the drivers will want to use the Generic
+ScatterWalk in case the hardware needs to be fed separate chunks of the
+scatterlist which contains the plaintext and will contain the
+ciphertext. Please refer to the ScatterWalk interface offered by the
+Linux kernel scatter / gather list implementation.
+
+Hashing [HASH]
+--------------
+
+Example of transformations: crc32, md5, sha1, sha256,...
+
+Registering And Unregistering The Transformation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are multiple ways to register a HASH transformation, depending on
+whether the transformation is synchronous [SHASH] or asynchronous
+[AHASH] and the amount of HASH transformations we are registering. You
+can find the prototypes defined in include/crypto/internal/hash.h:
+
+::
+
+       int crypto_register_ahash(struct ahash_alg *alg);
+
+       int crypto_register_shash(struct shash_alg *alg);
+       int crypto_register_shashes(struct shash_alg *algs, int count);
+
+
+The respective counterparts for unregistering the HASH transformation
+are as follows:
+
+::
+
+       int crypto_unregister_ahash(struct ahash_alg *alg);

+Kernel Crypto API Interface Specification
+=========================================
+
+Introduction
+------------
+
+The kernel crypto API offers a rich set of cryptographic ciphers as well
+as other data transformation mechanisms and methods to invoke these.
+This document contains a description of the API and provides example
+code.
+
+To understand and properly use the kernel crypto API a brief explanation
+of its structure is given. Based on the architecture, the API can be
+separated into different components. Following the architecture
+specification, hints to developers of ciphers are provided. Pointers to
+the API function call documentation are given at the end.
+
+The kernel crypto API refers to all algorithms as "transformations".
+Therefore, a cipher handle variable usually has the name "tfm". Besides
+cryptographic operations, the kernel crypto API also knows compression
+transformations and handles them the same way as ciphers.
+
+The kernel crypto API serves the following entity types:
+
+-  consumers requesting cryptographic services
+
+-  data transformation implementations (typically ciphers) that can be
+   called by consumers using the kernel crypto API
+
+This specification is intended for consumers of the kernel crypto API as
+well as for developers implementing ciphers. This API specification,
+however, does not discuss all API calls available to data transformation
+implementations (i.e. implementations of ciphers and other
+transformations (such as CRC or even compression algorithms) that can
+register with the kernel crypto API).
+
+Note: The terms "transformation" and cipher algorithm are used
+interchangeably.
+
+Terminology
+-----------
+
+The transformation implementation is an actual code or interface to
+hardware which implements a certain transformation with precisely
+defined behavior.
+
+The transformation object (TFM) is an instance of a transformation
+implementation. There can be multiple transformation objects associated
+with a single transformation implementation. Each of those
+transformation objects is held by a crypto API consumer or another
+transformation. Transformation object is allocated when a crypto API
+consumer requests a transformation implementation. The consumer is then
+provided with a structure, which contains a transformation object (TFM).
+
+The structure that contains transformation objects may also be referred
+to as a "cipher handle". Such a cipher handle is always subject to the
+following phases that are reflected in the API calls applicable to such
+a cipher handle:
+
+1. Initialization of a cipher handle.
+
+2. Execution of all intended cipher operations applicable for the handle
+   where the cipher handle must be furnished to every API call.
+
+3. Destruction of a cipher handle.
+
+When using the initialization API calls, a cipher handle is created and
+returned to the consumer. Therefore, please refer to all initialization
+API calls that refer to the data structure type a consumer is expected
+to receive and subsequently to use. The initialization API calls have
+all the same naming conventions of crypto_alloc\*.
+
+The transformation context is private data associated with the
+transformation object.

+User Space Interface
+====================
+
+Introduction
+------------
+
+The concepts of the kernel crypto API visible to kernel space is fully
+applicable to the user space interface as well. Therefore, the kernel
+crypto API high level discussion for the in-kernel use cases applies
+here as well.
+
+The major difference, however, is that user space can only act as a
+consumer and never as a provider of a transformation or cipher
+algorithm.
+
+The following covers the user space interface exported by the kernel
+crypto API. A working example of this description is libkcapi that can
+be obtained from [1]. That library can be used by user space
+applications that require cryptographic services from the kernel.
+
+Some details of the in-kernel kernel crypto API aspects do not apply to
+user space, however. This includes the difference between synchronous
+and asynchronous invocations. The user space API call is fully
+synchronous.
+
+[1] http://www.chronox.de/libkcapi.html
+
+User Space API General Remarks
+------------------------------
+
+The kernel crypto API is accessible from user space. Currently, the
+following ciphers are accessible:
+
+-  Message digest including keyed message digest (HMAC, CMAC)
+
+-  Symmetric ciphers
+
+-  AEAD ciphers
+
+-  Random Number Generators
+
+The interface is provided via socket type using the type AF_ALG. In
+addition, the setsockopt option type is SOL_ALG. In case the user space
+header files do not export these flags yet, use the following macros:
+
+::
+
+    #ifndef AF_ALG
+    #define AF_ALG 38
+    #endif
+    #ifndef SOL_ALG
+    #define SOL_ALG 279
+    #endif
+
+
+A cipher is accessed with the same name as done for the in-kernel API
+calls. This includes the generic vs. unique naming schema for ciphers as
+well as the enforcement of priorities for generic names.
+
+To interact with the kernel crypto API, a socket must be created by the
+user space application. User space invokes the cipher operation with the
+send()/write() system call family. The result of the cipher operation is
+obtained with the read()/recv() system call family.
+
+The following API calls assume that the socket descriptor is already
+opened by the user space application and discusses only the kernel
+crypto API specific invocations.
+
+To initialize the socket interface, the following sequence has to be
+performed by the consumer:
+
+1. Create a socket of type AF_ALG with the struct sockaddr_alg
+   parameter specified below for the different cipher types.
+
+2. Invoke bind with the socket descriptor
+
+3. Invoke accept with the socket descriptor. The accept system call
+   returns a new file descriptor that is to be used to interact with the
+   particular cipher instance. When invoking send/write or recv/read
+   system calls to send data to the kernel or obtain data from the
+   kernel, the file descriptor returned by accept must be used.
+
+In-place Cipher operation
+-------------------------
+
+Just like the in-kernel operation of the kernel crypto API, the user
+space interface allows the cipher operation in-place. That means that
+the input buffer used for the send/write system call and the output
+buffer used by the read/recv system call may be one and the same. This
+is of particular interest for symmetric cipher operations where a
+copying of the output data to its final destination can be avoided.
+
+If a consumer on the other hand wants to maintain the plaintext and the
+ciphertext in different memory locations, all a consumer needs to do is
+to provide different memory pointers for the encryption and decryption
+operation.
+
+Message Digest API
+------------------
+
+The message digest type to be used for the cipher operation is selected
+when invoking the bind syscall. bind requires the caller to provide a
+filled struct sockaddr data structure. This data structure must be
+filled as follows:
+
+::
+
+    struct sockaddr_alg sa = {
+        .salg_family = AF_ALG,
+        .salg_type = "hash", /* this selects the hash logic in the kernel */
+        .salg_name = "sha1" /* this is the cipher name */
+    };
+
+
+The salg_type value "hash" applies to message digests and keyed message
+digests. Though, a keyed message digest is referenced by the appropriate
+salg_name. Please see below for the setsockopt interface that explains
+how the key can be set for a keyed message digest.
+
+Using the send() system call, the application provides the data that
+should be processed with the message digest. The send system call allows
+the following flags to be specified:
+
+-  MSG_MORE: If this flag is set, the send system call acts like a
+   message digest update function where the final hash is not yet
+   calculated. If the flag is not set, the send system call calculates
+   the final message digest immediately.
+
+With the recv() system call, the application can read the message digest
+from the kernel crypto API. If the buffer is too small for the message
+digest, the flag MSG_TRUNC is set by the kernel.
+
+In order to set a message digest key, the calling application must use
+the setsockopt() option of ALG_SET_KEY. If the key is not set the HMAC
+operation is performed without the initial HMAC state change caused by
+the key.
+
+Symmetric Cipher API
+--------------------
+
+The operation is very similar to the message digest discussion. During
+initialization, the struct sockaddr data structure must be filled as
+follows:
+
+::
+
+    struct sockaddr_alg sa = {
+        .salg_family = AF_ALG,
+        .salg_type = "skcipher", /* this selects the symmetric cipher */
+        .salg_name = "cbc(aes)" /* this is the cipher name */
+    };
+
+
+Before data can be sent to the kernel using the write/send system call
+family, the consumer must set the key. The key setting is described with
+the setsockopt invocation below.
+
+Using the sendmsg() system call, the application provides the data that
+should be processed for encryption or decryption. In addition, the IV is
+specified with the data structure provided by the sendmsg() system call.
+
+The sendmsg system call parameter of struct msghdr is embedded into the
+struct cmsghdr data structure. See recv(2) and cmsg(3) for more
+information on how the cmsghdr data structure is used together with the
+send/recv system call family. That cmsghdr data structure holds the
+following information specified with a separate header instances:
+
+-  specification of the cipher operation type with one of these flags:
+
+   -  ALG_OP_ENCRYPT - encryption of data
+
+   -  ALG_OP_DECRYPT - decryption of data
+
+-  specification of the IV information marked with the flag ALG_SET_IV
+
+The send system call family allows the following flag to be specified:
+
+-  MSG_MORE: If this flag is set, the send system call acts like a
+   cipher update function where more input data is expected with a
+   subsequent invocation of the send system call.
+
+Note: The kernel reports -EINVAL for any unexpected data. The caller
+must make sure that all data matches the constraints given in
+/proc/crypto for the selected cipher.
+
+With the recv() system call, the application can read the result of the
+cipher operation from the kernel crypto API. The output buffer must be
+at least as large as to hold all blocks of the encrypted or decrypted
+data. If the output data size is smaller, only as many blocks are
+returned that fit into that output buffer size.
+
+AEAD Cipher API
+---------------
+
+The operation is very similar to the symmetric cipher discussion. During
+initialization, the struct sockaddr data structure must be filled as
+follows:
+
+::
+
+    struct sockaddr_alg sa = {
+        .salg_family = AF_ALG,
+        .salg_type = "aead", /* this selects the symmetric cipher */
+        .salg_name = "gcm(aes)" /* this is the cipher name */
+    };
+
+
+Before data can be sent to the kernel using the write/send system call
+family, the consumer must set the key. The key setting is described with
+the setsockopt invocation below.
+
+In addition, before data can be sent to the kernel using the write/send
+system call family, the consumer must set the authentication tag size.
+To set the authentication tag size, the caller must use the setsockopt
+invocation described below.
+
+Using the sendmsg() system call, the application provides the data that
+should be processed for encryption or decryption. In addition, the IV is
+specified with the data structure provided by the sendmsg() system call.
+
+The sendmsg system call parameter of struct msghdr is embedded into the
+struct cmsghdr data structure. See recv(2) and cmsg(3) for more
+information on how the cmsghdr data structure is used together with the
+send/recv system call family. That cmsghdr data structure holds the
+following information specified with a separate header instances:
+
+-  specification of the cipher operation type with one of these flags:
+
+   -  ALG_OP_ENCRYPT - encryption of data
+
+   -  ALG_OP_DECRYPT - decryption of data
+
+-  specification of the IV information marked with the flag ALG_SET_IV
+
+-  specification of the associated authentication data (AAD) with the
+   flag ALG_SET_AEAD_ASSOCLEN. The AAD is sent to the kernel together
+   with the plaintext / ciphertext. See below for the memory structure.
+
+The send system call family allows the following flag to be specified:
+
+-  MSG_MORE: If this flag is set, the send system call acts like a
+   cipher update function where more input data is expected with a
+   subsequent invocation of the send system call.
+
+Note: The kernel reports -EINVAL for any unexpected data. The caller
+must make sure that all data matches the constraints given in
+/proc/crypto for the selected cipher.
+
+With the recv() system call, the application can read the result of the
+cipher operation from the kernel crypto API. The output buffer must be
+at least as large as defined with the memory structure below. If the
+output data size is smaller, the cipher operation is not performed.
+
+The authenticated decryption operation may indicate an integrity error.
+Such breach in integrity is marked with the -EBADMSG error code.
+
+AEAD Memory Structure
+~~~~~~~~~~~~~~~~~~~~~
+
+The AEAD cipher operates with the following information that is
+communicated between user and kernel space as one data stream:
+
+-  plaintext or ciphertext
+
+-  associated authentication data (AAD)
+
+-  authentication tag
+
+The sizes of the AAD and the authentication tag are provided with the
+sendmsg and setsockopt calls (see there). As the kernel knows the size
+of the entire data stream, the kernel is now able to calculate the right
+offsets of the data components in the data stream.
+
+The user space caller must arrange the aforementioned information in the
+following order:
+
+-  AEAD encryption input: AAD \|\| plaintext
+
+-  AEAD decryption input: AAD \|\| ciphertext \|\| authentication tag
+
+The output buffer the user space caller provides must be at least as
+large to hold the following data:
+
+-  AEAD encryption output: ciphertext \|\| authentication tag
+
+-  AEAD decryption output: plaintext
+
+Random Number Generator API
+---------------------------
+
+Again, the operation is very similar to the other APIs. During
+initialization, the struct sockaddr data structure must be filled as
+follows:
+
+::
+
+    struct sockaddr_alg sa = {
+        .salg_family = AF_ALG,
+        .salg_type = "rng", /* this selects the symmetric cipher */
+        .salg_name = "drbg_nopr_sha256" /* this is the cipher name */
+    };
+
+
+Depending on the RNG type, the RNG must be seeded. The seed is provided
+using the setsockopt interface to set the key. For example, the
+ansi_cprng requires a seed. The DRBGs do not require a seed, but may be
+seeded.
+
+Using the read()/recvmsg() system calls, random numbers can be obtained.
+The kernel generates at most 128 bytes in one call. If user space
+requires more data, multiple calls to read()/recvmsg() must be made.
+
+WARNING: The user space caller may invoke the initially mentioned accept
+system call multiple times. In this case, the returned file descriptors
+have the same state.
+
+Zero-Copy Interface
+-------------------
+
+In addition to the send/write/read/recv system call family, the AF_ALG
+interface can be accessed with the zero-copy interface of
+splice/vmsplice. As the name indicates, the kernel tries to avoid a copy
+operation into kernel space.
+
+The zero-copy operation requires data to be aligned at the page
+boundary. Non-aligned data can be used as well, but may require more
+operations of the kernel which would defeat the speed gains obtained
+from the zero-copy interface.
+
+The system-interent limit for the size of one zero-copy operation is 16
+pages. If more data is to be sent to AF_ALG, user space must slice the
+input into segments with a maximum size of 16 pages.
+
+Zero-copy can be used with the following code example (a complete
+working example is provided with libkcapi):
+
+::
+
+    int pipes[2];
+
+    pipe(pipes);
+    /* input data in iov */
+    vmsplice(pipes[1], iov, iovlen, SPLICE_F_GIFT);
+    /* opfd is the file descriptor returned from accept() system call */
+    splice(pipes[0], NULL, opfd, NULL, ret, 0);
+    read(opfd, out, outlen);
+
+
+Setsockopt Interface
+--------------------
+
+In addition to the read/recv and send/write system call handling to send
+and retrieve data subject to the cipher operation, a consumer also needs
+to set the additional information for the cipher operation. This
+additional information is set using the setsockopt system call that must
+be invoked with the file descriptor of the open cipher (i.e. the file
+descriptor returned by the accept system call).
+
+Each setsockopt invocation must use the level SOL_ALG.
+
+The setsockopt interface allows setting the following data using the
+mentioned optname:
+
+-  ALG_SET_KEY -- Setting the key. Key setting is applicable to:
+
+   -  the skcipher cipher type (symmetric ciphers)
+
+   -  the hash cipher type (keyed message digests)
+
+   -  the AEAD cipher type
+
+   -  the RNG cipher type to provide the seed
+
+-  ALG_SET_AEAD_AUTHSIZE -- Setting the authentication tag size for
+   AEAD ciphers. For a encryption operation, the authentication tag of
+   the given size will be generated. For a decryption operation, the
+   provided ciphertext is assumed to contain an authentication tag of
+   the given size (see section about AEAD memory layout below).
+
+User space API example
+----------------------
+
+Please see [1] for libkcapi which provides an easy-to-use wrapper around
+the aforementioned Netlink kernel interface. [1] also contains a test
+application that invokes all libkcapi API calls.

+==========================================
+ARM CPUs capacity bindings
+==========================================
+
+==========================================
+1 - Introduction
+==========================================
+
+ARM systems may be configured to have cpus with different power/performance
+characteristics within the same chip. In this case, additional information has
+to be made available to the kernel for it to be aware of such differences and
+take decisions accordingly.
+
+==========================================
+2 - CPU capacity definition
+==========================================
+
+CPU capacity is a number that provides the scheduler information about CPUs
+heterogeneity. Such heterogeneity can come from micro-architectural differences
+(e.g., ARM big.LITTLE systems) or maximum frequency at which CPUs can run
+(e.g., SMP systems with multiple frequency domains). Heterogeneity in this
+context is about differing performance characteristics; this binding tries to
+capture a first-order approximation of the relative performance of CPUs.
+
+CPU capacities are obtained by running a suitable benchmark. This binding makes
+no guarantees on the validity or suitability of any particular benchmark, the
+final capacity should, however, be:
+
+* A "single-threaded" or CPU affine benchmark
+* Divided by the running frequency of the CPU executing the benchmark
+* Not subject to dynamic frequency scaling of the CPU
+
+For the time being we however advise usage of the Dhrystone benchmark. What
+above thus becomes:
+
+CPU capacities are obtained by running the Dhrystone benchmark on each CPU at
+max frequency (with caches enabled). The obtained DMIPS score is then divided
+by the frequency (in MHz) at which the benchmark has been run, so that
+DMIPS/MHz are obtained.  Such values are then normalized w.r.t. the highest
+score obtained in the system.
+
+==========================================
+3 - capacity-dmips-mhz
+==========================================
+
+capacity-dmips-mhz is an optional cpu node [1] property: u32 value
+representing CPU capacity expressed in normalized DMIPS/MHz. At boot time, the
+maximum frequency available to the cpu is then used to calculate the capacity
+value internally used by the kernel.
+
+capacity-dmips-mhz property is all-or-nothing: if it is specified for a cpu
+node, it has to be specified for every other cpu nodes, or the system will
+fall back to the default capacity value for every CPU. If cpufreq is not
+available, final capacities are calculated by directly using capacity-dmips-
+mhz values (normalized w.r.t. the highest value found while parsing the DT).
+
+===========================================
+4 - Examples
+===========================================
+
+Example 1 (ARM 64-bit, 6-cpu system, two clusters):
+capacities-dmips-mhz are scaled w.r.t. 1024 (cpu@0 and cpu@1)
+supposing cluster0@max-freq=1100 and custer1@max-freq=850,
+final capacities are 1024 for cluster0 and 446 for cluster1

+Texas Instruments System Control Interface (TI-SCI) Message Protocol
+--------------------------------------------------------------------
+
+Texas Instrument's processors including those belonging to Keystone generation
+of processors have separate hardware entity which is now responsible for the
+management of the System on Chip (SoC) system. These include various system
+level functions as well.
+
+An example of such an SoC is K2G, which contains the system control hardware
+block called Power Management Micro Controller (PMMC). This hardware block is
+initialized early into boot process and provides services to Operating Systems
+on multiple processors including ones running Linux.
+
+See http://processors.wiki.ti.com/index.php/TISCI for protocol definition.
+
+TI-SCI controller Device Node:
+=============================
+
+The TI-SCI node describes the Texas Instrument's System Controller entity node.
+This parent node may optionally have additional children nodes which describe
+specific functionality such as clocks, power domain, reset or additional
+functionality as may be required for the SoC. This hierarchy also describes the
+relationship between the TI-SCI parent node to the child node.
+
+Required properties:
+-------------------
+- compatible: should be "ti,k2g-sci"
+- mbox-names:
+	"rx" - Mailbox corresponding to receive path
+	"tx" - Mailbox corresponding to transmit path
+
+- mboxes: Mailboxes corresponding to the mbox-names. Each value of the mboxes
+	  property should contain a phandle to the mailbox controller device
+	  node and an args specifier that will be the phandle to the intended
+	  sub-mailbox child node to be used for communication.
+
+See Documentation/devicetree/bindings/mailbox/mailbox.txt for more details
+about the generic mailbox controller and client driver bindings. Also see
+Documentation/devicetree/bindings/mailbox/ti,message-manager.txt for typical
+controller that is used to communicate with this System controllers.
+
+Optional Properties:
+-------------------
+- reg-names:
+	debug_messages - Map the Debug message region
+- reg:  register space corresponding to the debug_messages
+- ti,system-reboot-controller: If system reboot can be triggered by SoC reboot
+
+Example (K2G):
+-------------
+	pmmc: pmmc {
+		compatible = "ti,k2g-sci";
+		mbox-names = "rx", "tx";
+		mboxes= <&msgmgr &msgmgr_proxy_pmmc_rx>,
+			<&msgmgr &msgmgr_proxy_pmmc_tx>;
+		reg-names = "debug_messages";
+		reg = <0x02921800 0x800>;
+	};
+
+
+TI-SCI Client Device Node:
+=========================
+
+Client nodes are maintained as children of the relevant TI-SCI device node.
+
+Example (K2G):
+-------------
+	pmmc: pmmc {
+		compatible = "ti,k2g-sci";
+		...
+
+		my_clk_node: clk_node {
+			...
+			...
+		};
+
+		my_pd_node: pd_node {
+			...
+			...
+		};

+Device tree bindings for NVIDIA Tegra Generic Memory Interface bus
+
+The Generic Memory Interface bus enables memory transfers between internal and
+external memory. Can be used to attach various high speed devices such as
+synchronous/asynchronous NOR, FPGA, UARTS and more.
+
+The actual devices are instantiated from the child nodes of a GMI node.
+
+Required properties:
+ - compatible : Should contain one of the following:
+        For Tegra20 must contain "nvidia,tegra20-gmi".
+        For Tegra30 must contain "nvidia,tegra30-gmi".
+ - reg: Should contain GMI controller registers location and length.
+ - clocks: Must contain an entry for each entry in clock-names.
+ - clock-names: Must include the following entries: "gmi"
+ - resets : Must contain an entry for each entry in reset-names.
+ - reset-names : Must include the following entries: "gmi"
+ - #address-cells: The number of cells used to represent physical base
+   addresses in the GMI address space. Should be 2.
+ - #size-cells: The number of cells used to represent the size of an address
+   range in the GMI address space. Should be 1.
+ - ranges: Must be set up to reflect the memory layout with three integer values
+   for each chip-select line in use (only one entry is supported, see below
+   comments):
+   <cs-number> <offset> <physical address of mapping> <size>
+
+Note that the GMI controller does not have any internal chip-select address
+decoding, because of that chip-selects either need to be managed via software
+or by employing external chip-select decoding logic.
+
+If external chip-select logic is used to support multiple devices it is assumed
+that the devices use the same timing and so are probably the same type. It also
+assumes that they can fit in the 256MB address range. In this case only one
+child device is supported which represents the active chip-select line, see
+examples for more insight.
+
+The chip-select number is decoded from the child nodes second address cell of
+'ranges' property, if 'ranges' property is not present or empty chip-select will
+then be decoded from the first cell of the 'reg' property.
+
+Optional child cs node properties:
+
+ - nvidia,snor-data-width-32bit: Use 32bit data-bus, default is 16bit.
+ - nvidia,snor-mux-mode: Enable address/data MUX mode.
+ - nvidia,snor-rdy-active-before-data: Assert RDY signal one cycle before data.
+   If omitted it will be asserted with data.
+ - nvidia,snor-rdy-active-high: RDY signal is active high
+ - nvidia,snor-adv-active-high: ADV signal is active high
+ - nvidia,snor-oe-active-high: WE/OE signal is active high
+ - nvidia,snor-cs-active-high: CS signal is active high
+
+  Note that there is some special handling for the timing values.
+  From Tegra TRM:
+  Programming 0 means 1 clock cycle: actual cycle = programmed cycle + 1
+
+ - nvidia,snor-muxed-width: Number of cycles MUX address/data asserted on the
+   bus. Valid values are 0-15, default is 1
+ - nvidia,snor-hold-width: Number of cycles CE stays asserted after the
+   de-assertion of WR_N (in case of SLAVE/MASTER Request) or OE_N
+   (in case of MASTER Request). Valid values are 0-15, default is 1
+ - nvidia,snor-adv-width: Number of cycles during which ADV stays asserted.
+   Valid values are 0-15, default is 1.
+ - nvidia,snor-ce-width: Number of cycles before CE is asserted.
+   Valid values are 0-15, default is 4
+ - nvidia,snor-we-width: Number of cycles during which WE stays asserted.
+   Valid values are 0-15, default is 1
+ - nvidia,snor-oe-width: Number of cycles during which OE stays asserted.
+   Valid values are 0-255, default is 1
+ - nvidia,snor-wait-width: Number of cycles before READY is asserted.
+   Valid values are 0-255, default is 3

+controllers with a simple-bus node since they are all connected to the same

+
+Required Properties:

+- compatible: should be "rockchip,rk1108-cru"
+- reg: physical base address of the controller and length of memory mapped

+Optional Properties:
+
+- rockchip,grf: phandle to the syscon managing the "general register files"
+  If missing pll rates are not changeable, due to the missing pll lock status.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. All available clocks are defined as
+preprocessor macros in the dt-bindings/clock/rk1108-cru.h headers and can be
+used in device tree sources. Similar macros exist for the reset sources in
+these files.
+
+External clocks:
+
+There are several clocks that are generated outside the SoC. It is expected
+that they are defined using standard clock bindings with following
+clock-output-names:
+ - "xin24m" - crystal input - required,
+ - "ext_vip" - external VIP clock - optional
+ - "ext_i2s" - external I2S clock - optional
+ - "ext_gmac" - external GMAC clock - optional
+ - "hdmiphy" - external clock input derived from HDMI PHY - optional
+ - "usbphy" - external clock input derived from USB PHY - optional

+Broadcom AVS mail box and interrupt register bindings
+=====================================================
+
+A total of three DT nodes are required. One node (brcm,avs-cpu-data-mem)
+references the mailbox register used to communicate with the AVS CPU[1]. The
+second node (brcm,avs-cpu-l2-intr) is required to trigger an interrupt on
+the AVS CPU. The interrupt tells the AVS CPU that it needs to process a
+command sent to it by a driver. Interrupting the AVS CPU is mandatory for
+commands to be processed.
+
+The interface also requires a reference to the AVS host interrupt controller,
+so a driver can react to interrupts generated by the AVS CPU whenever a command
+has been processed. See [2] for more information on the brcm,l2-intc node.
+
+[1] The AVS CPU is an independent co-processor that runs proprietary
+firmware. On some SoCs, this firmware supports DFS and DVFS in addition to
+Adaptive Voltage Scaling.

+Amlogic Meson Display Controller
+================================
+
+The Amlogic Meson Display controller is composed of several components
+that are going to be documented below:
+
+DMC|---------------VPU (Video Processing Unit)----------------|------HHI------|
+   | vd1   _______     _____________    _________________     |               |

+M  |-------|______|----|____________|   |________________|    |               |
+___|__________________________________________________________|_______________|
+
+
+VIU: Video Input Unit
+---------------------
+
+The Video Input Unit is in charge of the pixel scanout from the DDR memory.
+It fetches the frames addresses, stride and parameters from the "Canvas" memory.
+This part is also in charge of the CSC (Colorspace Conversion).
+It can handle 2 OSD Planes and 2 Video Planes.
+
+VPP: Video Post Processing
+--------------------------
+
+The Video Post Processing is in charge of the scaling and blending of the
+various planes into a single pixel stream.
+There is a special "pre-blending" used by the video planes with a dedicated
+scaler and a "post-blending" to merge with the OSD Planes.
+The OSD planes also have a dedicated scaler for one of the OSD.
+
+VENC: Video Encoders
+--------------------
+
+The VENC is composed of the multiple pixel encoders :
+ - ENCI : Interlace Video encoder for CVBS and Interlace HDMI
+ - ENCP : Progressive Video Encoder for HDMI
+ - ENCL : LCD LVDS Encoder
+The VENC Unit gets a Pixel Clocks (VCLK) from a dedicated HDMI PLL and clock
+tree and provides the scanout clock to the VPP and VIU.
+The ENCI is connected to a single VDAC for Composite Output.
+The ENCI and ENCP are connected to an on-chip HDMI Transceiver.
+
+Device Tree Bindings:

+	- vpu
+	- hhi
+	- dmc
+- reg-names: should contain the names of the previous memory regions

+NVIDIA Tegra Boot and Power Management Processor (BPMP)
+
+The BPMP is a specific processor in Tegra chip, which is designed for
+booting process handling and offloading the power management, clock
+management, and reset control tasks from the CPU. The binding document
+defines the resources that would be used by the BPMP firmware driver,
+which can create the interprocessor communication (IPC) between the CPU
+and BPMP.
+
+Required properties:
+- name : Should be bpmp
+- compatible
+    Array of strings
+    One of:
+    - "nvidia,tegra186-bpmp"
+- mboxes : The phandle of mailbox controller and the mailbox specifier.
+- shmem : List of the phandle of the TX and RX shared memory area that
+	  the IPC between CPU and BPMP is based on.
+- #clock-cells : Should be 1.
+- #power-domain-cells : Should be 1.
+- #reset-cells : Should be 1.
+
+This node is a mailbox consumer. See the following files for details of
+the mailbox subsystem, and the specifiers implemented by the relevant
+provider(s):
+
+- .../mailbox/mailbox.txt
+- .../mailbox/nvidia,tegra186-hsp.txt
+
+This node is a clock, power domain, and reset provider. See the following
+files for general documentation of those features, and the specifiers
+implemented by this node:
+
+- .../clock/clock-bindings.txt
+- <dt-bindings/clock/tegra186-clock.h>
+- ../power/power_domain.txt
+- <dt-bindings/power/tegra186-powergate.h>
+- .../reset/reset.txt
+- <dt-bindings/reset/tegra186-reset.h>
+
+The BPMP implements some services which must be represented by separate nodes.
+For example, it can provide access to certain I2C controllers, and the I2C
+bindings represent each I2C controller as a device tree node. Such nodes should
+be nested directly inside the main BPMP node.
+
+Software can determine whether a child node of the BPMP node represents a device
+by checking for a compatible property. Any node with a compatible property
+represents a device that can be instantiated. Nodes without a compatible
+property may be used to provide configuration information regarding the BPMP
+itself, although no such configuration nodes are currently defined by this
+binding.
+
+The BPMP firmware defines no single global name-/numbering-space for such
+services. Put another way, the numbering scheme for I2C buses is distinct from
+the numbering scheme for any other service the BPMP may provide (e.g. a future
+hypothetical SPI bus service). As such, child device nodes will have no reg
+property, and the BPMP node will have no #address-cells or #size-cells property.
+
+The shared memory bindings for BPMP
+-----------------------------------
+
+The shared memory area for the IPC TX and RX between CPU and BPMP are
+predefined and work on top of sysram, which is an SRAM inside the chip.
+
+See ".../sram/sram.txt" for the bindings.
+

+Introduction
+============
+
+FPGA Regions represent FPGA's and partial reconfiguration regions of FPGA's in
+the Device Tree.  FPGA Regions provide a way to program FPGAs under device tree
+control.
+
+This device tree binding document hits some of the high points of FPGA usage and
+attempts to include terminology used by both major FPGA manufacturers.  This
+document isn't a replacement for any manufacturers specifications for FPGA
+usage.
+
+
+Terminology
+===========
+
+Full Reconfiguration
+ * The entire FPGA is programmed.
+
+Partial Reconfiguration (PR)
+ * A section of an FPGA is reprogrammed while the rest of the FPGA is not
+   affected.
+ * Not all FPGA's support PR.
+
+Partial Reconfiguration Region (PRR)
+ * Also called a "reconfigurable partition"
+ * A PRR is a specific section of a FPGA reserved for reconfiguration.
+ * A base (or static) FPGA image may create a set of PRR's that later may
+   be independently reprogrammed many times.
+ * The size and specific location of each PRR is fixed.
+ * The connections at the edge of each PRR are fixed.  The image that is loaded
+   into a PRR must fit and must use a subset of the region's connections.
+ * The busses within the FPGA are split such that each region gets its own
+   branch that may be gated independently.
+
+Persona
+ * Also called a "partial bit stream"
+ * An FPGA image that is designed to be loaded into a PRR.  There may be
+   any number of personas designed to fit into a PRR, but only one at at time
+   may be loaded.
+ * A persona may create more regions.
+
+FPGA Bridge
+ * FPGA Bridges gate bus signals between a host and FPGA.
+ * FPGA Bridges should be disabled while the FPGA is being programmed to
+   prevent spurious signals on the cpu bus and to the soft logic.
+ * FPGA bridges may be actual hardware or soft logic on an FPGA.
+ * During Full Reconfiguration, hardware bridges between the host and FPGA
+   will be disabled.
+ * During Partial Reconfiguration of a specific region, that region's bridge
+   will be used to gate the busses.  Traffic to other regions is not affected.
+ * In some implementations, the FPGA Manager transparantly handles gating the
+   buses, eliminating the need to show the hardware FPGA bridges in the
+   device tree.
+ * An FPGA image may create a set of reprogrammable regions, each having its
+   own bridge and its own split of the busses in the FPGA.
+
+FPGA Manager
+ * An FPGA Manager is a hardware block that programs an FPGA under the control
+   of a host processor.
+
+Base Image
+ * Also called the "static image"
+ * An FPGA image that is designed to do full reconfiguration of the FPGA.
+ * A base image may set up a set of partial reconfiguration regions that may
+   later be reprogrammed.

+Figure 1: An FPGA set up with a base image that created three regions.  Each
+region (PRR0-2) gets its own split of the busses that is independently gated by
+a soft logic bridge (Bridge0-2) in the FPGA.  The contents of each PRR can be
+reprogrammed independently while the rest of the system continues to function.
+
+
+Sequence
+========
+
+When a DT overlay that targets a FPGA Region is applied, the FPGA Region will
+do the following:
+
+ 1. Disable appropriate FPGA bridges.
+ 2. Program the FPGA using the FPGA manager.
+ 3. Enable the FPGA bridges.
+ 4. The Device Tree overlay is accepted into the live tree.
+ 5. Child devices are populated.
+
+When the overlay is removed, the child nodes will be removed and the FPGA Region
+will disable the bridges.
+
+
+FPGA Region
+===========
+
+FPGA Regions represent FPGA's and FPGA PR regions in the device tree.  An FPGA
+Region brings together the elements needed to program on a running system and
+add the child devices:
+
+ * FPGA Manager
+ * FPGA Bridges
+ * image-specific information needed to to the programming.
+ * child nodes
+
+The intended use is that a Device Tree overlay (DTO) can be used to reprogram an
+FPGA while an operating system is running.
+
+An FPGA Region that exists in the live Device Tree reflects the current state.
+If the live tree shows a "firmware-name" property or child nodes under a FPGA
+Region, the FPGA already has been programmed.  A DTO that targets a FPGA Region
+and adds the "firmware-name" property is taken as a request to reprogram the
+FPGA.  After reprogramming is successful, the overlay is accepted into the live
+tree.
+
+The base FPGA Region in the device tree represents the FPGA and supports full
+reconfiguration.  It must include a phandle to an FPGA Manager.  The base
+FPGA region will be the child of one of the hardware bridges (the bridge that
+allows register access) between the cpu and the FPGA.  If there are more than
+one bridge to control during FPGA programming, the region will also contain a
+list of phandles to the additional hardware FPGA Bridges.
+
+For partial reconfiguration (PR), each PR region will have an FPGA Region.
+These FPGA regions are children of FPGA bridges which are then children of the
+base FPGA region.  The "Full Reconfiguration to add PRR's" example below shows
+this.
+
+If an FPGA Region does not specify a FPGA Manager, it will inherit the FPGA
+Manager specified by its ancestor FPGA Region.  This supports both the case
+where the same FPGA Manager is used for all of a FPGA as well the case where
+a different FPGA Manager is used for each region.
+
+FPGA Regions do not inherit their ancestor FPGA regions' bridges.  This prevents
+shutting down bridges that are upstream from the other active regions while one
+region is getting reconfigured (see Figure 1 above).  During PR, the FPGA's
+hardware bridges remain enabled.  The PR regions' bridges will be FPGA bridges
+within the static image of the FPGA.
+
+Required properties:
+- compatible : should contain "fpga-region"
+- fpga-mgr : should contain a phandle to an FPGA Manager.  Child FPGA Regions
+	inherit this property from their ancestor regions.  A fpga-mgr property
+	in a region will override any inherited FPGA manager.
+- #address-cells, #size-cells, ranges : must be present to handle address space
+	mapping for child nodes.
+
+Optional properties:
+- firmware-name : should contain the name of an FPGA image file located on the
+	firmware search path.  If this property shows up in a live device tree
+	it indicates that the FPGA has already been programmed with this image.
+	If this property is in an overlay targeting a FPGA region, it is a
+	request to program the FPGA with that image.
+- fpga-bridges : should contain a list of phandles to FPGA Bridges that must be
+	controlled during FPGA programming along with the parent FPGA bridge.
+	This property is optional if the FPGA Manager handles the bridges.
+        If the fpga-region is  the child of a fpga-bridge, the list should not
+        contain the parent bridge.
+- partial-fpga-config : boolean, set if partial reconfiguration is to be done,
+	otherwise full reconfiguration is done.
+- external-fpga-config : boolean, set if the FPGA has already been configured
+	prior to OS boot up.
+- region-unfreeze-timeout-us : The maximum time in microseconds to wait for
+	bridges to successfully become enabled after the region has been
+	programmed.
+- region-freeze-timeout-us : The maximum time in microseconds to wait for
+	bridges to successfully become disabled before the region has been
+	programmed.
+- child nodes : devices in the FPGA after programming.
+
+In the example below, when an overlay is applied targeting fpga-region0,
+fpga_mgr is used to program the FPGA.  Two bridges are controlled during
+programming: the parent fpga_bridge0 and fpga_bridge1.  Because the region is
+the child of fpga_bridge0, only fpga_bridge1 needs to be specified in the
+fpga-bridges property.  During programming, these bridges are disabled, the
+firmware specified in the overlay is loaded to the FPGA using the FPGA manager
+specified in the region.  If FPGA programming succeeds, the bridges are
+reenabled and the overlay makes it into the live device tree.  The child devices
+are then populated.  If FPGA programming fails, the bridges are left disabled
+and the overlay is rejected.  The overlay's ranges property maps the lwhps
+bridge's region (0xff200000) and the hps bridge's region (0xc0000000) for use by
+the two child devices.

+
+
+Supported Use Models
+====================
+
+In all cases the live DT must have the FPGA Manager, FPGA Bridges (if any), and
+a FPGA Region.  The target of the Device Tree Overlay is the FPGA Region.  Some
+uses are specific to a FPGA device.
+
+ * No FPGA Bridges
+   In this case, the FPGA Manager which programs the FPGA also handles the
+   bridges behind the scenes.  No FPGA Bridge devices are needed for full
+   reconfiguration.
+
+ * Full reconfiguration with hardware bridges
+   In this case, there are hardware bridges between the processor and FPGA that
+   need to be controlled during full reconfiguration.  Before the overlay is
+   applied, the live DT must include the FPGA Manager, FPGA Bridges, and a
+   FPGA Region.  The FPGA Region is the child of the bridge that allows
+   register access to the FPGA.  Additional bridges may be listed in a
+   fpga-bridges property in the FPGA region or in the device tree overlay.
+
+ * Partial reconfiguration with bridges in the FPGA
+   In this case, the FPGA will have one or more PRR's that may be programmed
+   separately while the rest of the FPGA can remain active.  To manage this,
+   bridges need to exist in the FPGA that can gate the buses going to each FPGA
+   region while the buses are enabled for other sections.  Before any partial
+   reconfiguration can be done, a base FPGA image must be loaded which includes
+   PRR's with FPGA bridges.  The device tree should have a FPGA region for each
+   PRR.
+
+Device Tree Examples
+====================
+
+The intention of this section is to give some simple examples, focusing on
+the placement of the elements detailed above, especially:
+ * FPGA Manager
+ * FPGA Bridges
+ * FPGA Region
+ * ranges
+ * target-path or target
+
+For the purposes of this section, I'm dividing the Device Tree into two parts,
+each with its own requirements.  The two parts are:
+ * The live DT prior to the overlay being added
+ * The DT overlay
+
+The live Device Tree must contain an FPGA Region, an FPGA Manager, and any FPGA
+Bridges.  The FPGA Region's "fpga-mgr" property specifies the manager by phandle
+to handle programming the FPGA.  If the FPGA Region is the child of another FPGA
+Region, the parent's FPGA Manager is used.  If FPGA Bridges need to be involved,
+they are specified in the FPGA Region by the "fpga-bridges" property.  During
+FPGA programming, the FPGA Region will disable the bridges that are in its
+"fpga-bridges" list and will re-enable them after FPGA programming has
+succeeded.
+
+The Device Tree Overlay will contain:
+ * "target-path" or "target"
+   The insertion point where the the contents of the overlay will go into the
+   live tree.  target-path is a full path, while target is a phandle.
+ * "ranges"
+    The address space mapping from processor to FPGA bus(ses).
+ * "firmware-name"
+   Specifies the name of the FPGA image file on the firmware search
+   path.  The search path is described in the firmware class documentation.
+ * "partial-fpga-config"
+   This binding is a boolean and should be present if partial reconfiguration
+   is to be done.
+ * child nodes corresponding to hardware that will be loaded in this region of
+   the FPGA.

+=========================================================
+
+Live Device Tree contains:
+	fpga_mgr0: fpga-mgr@f8007000 {
+		compatible = "xlnx,zynq-devcfg-1.0";
+		reg = <0xf8007000 0x100>;

+

+			gpio-controller;
+			#gpio-cells = <0x2>;
+			xlnx,gpio-width= <0x6>;
+		};
+	};
+};
+
+Device Tree Example: Full Reconfiguration to add PRR's
+======================================================
+
+The base FPGA Region is specified similar to the first example above.
+
+This example programs the FPGA to have two regions that can later be partially
+configured.  Each region has its own bridge in the FPGA fabric.
+
+DT Overlay contains:
+/dts-v1/ /plugin/;
+/ {
+	fragment@0 {
+		target = <&fpga_region0>;
+		#address-cells = <1>;
+		#size-cells = <1>;
+		__overlay__ {
+			#address-cells = <1>;
+			#size-cells = <1>;
+
+			firmware-name = "base.rbf";
+
+			fpga-bridge@4400 {
+				compatible = "altr,freeze-bridge";
+				reg = <0x4400 0x10>;
+
+				fpga_region1: fpga-region1 {
+					compatible = "fpga-region";
+					#address-cells = <0x1>;
+					#size-cells = <0x1>;
+					ranges;
+				};
+			};
+
+			fpga-bridge@4420 {
+				compatible = "altr,freeze-bridge";
+				reg = <0x4420 0x10>;
+
+				fpga_region2: fpga-region2 {
+					compatible = "fpga-region";
+					#address-cells = <0x1>;
+					#size-cells = <0x1>;
+					ranges;
+				};
+			};
+		};
+	};
+};
+
+Device Tree Example: Partial Reconfiguration
+============================================
+
+This example reprograms one of the PRR's set up in the previous example.
+
+The sequence that occurs when this overlay is similar to the above, the only
+differences are that the FPGA is partially reconfigured due to the
+"partial-fpga-config" boolean and the only bridge that is controlled during
+programming is the FPGA based bridge of fpga_region1.
+
+/dts-v1/ /plugin/;
+/ {
+	fragment@0 {
+		target = <&fpga_region1>;
+		#address-cells = <1>;
+		#size-cells = <1>;
+		__overlay__ {
+			#address-cells = <1>;
+			#size-cells = <1>;
+
+			firmware-name = "soc_image2.rbf";
+			partial-fpga-config;
+
+			gpio@10040 {
+				compatible = "altr,pio-1.0";
+				reg = <0x10040 0x20>;
+				clocks = <0x2>;
+				altr,gpio-bank-width = <0x4>;
+				resetvalue = <0x0>;
+				#gpio-cells = <0x2>;
+				gpio-controller;
+			};
+		};
+	};
+};
+
+Constraints
+===========
+
+It is beyond the scope of this document to fully describe all the FPGA design
+constraints required to make partial reconfiguration work[1] [2] [3], but a few
+deserve quick mention.
+
+A persona must have boundary connections that line up with those of the partion
+or region it is designed to go into.
+
+During programming, transactions through those connections must be stopped and
+the connections must be held at a fixed logic level.  This can be achieved by
+FPGA Bridges that exist on the FPGA fabric prior to the partial reconfiguration.

+STMicroelectronics STM32 ADC device driver
+
+STM32 ADC is a successive approximation analog-to-digital converter.
+It has several multiplexed input channels. Conversions can be performed
+in single, continuous, scan or discontinuous mode. Result of the ADC is
+stored in a left-aligned or right-aligned 32-bit data register.
+Conversions can be launched in software or using hardware triggers.
+
+The analog watchdog feature allows the application to detect if the input
+voltage goes beyond the user-defined, higher or lower thresholds.
+
+Each STM32 ADC block can have up to 3 ADC instances.
+
+Each instance supports two contexts to manage conversions, each one has its
+own configurable sequence and trigger:
+- regular conversion can be done in sequence, running in background
+- injected conversions have higher priority, and so have the ability to
+  interrupt regular conversion sequence (either triggered in SW or HW).
+  Regular sequence is resumed, in case it has been interrupted.
+
+Contents of a stm32 adc root node:
+-----------------------------------
+Required properties:
+- compatible: Should be "st,stm32f4-adc-core".
+- reg: Offset and length of the ADC block register set.
+- interrupts: Must contain the interrupt for ADC block.
+- clocks: Clock for the analog circuitry (common to all ADCs).
+- clock-names: Must be "adc".
+- interrupt-controller: Identifies the controller node as interrupt-parent
+- vref-supply: Phandle to the vref input analog reference voltage.
+- #interrupt-cells = <1>;
+- #address-cells = <1>;
+- #size-cells = <0>;
+
+Optional properties:
+- A pinctrl state named "default" for each ADC channel may be defined to set
+  inX ADC pins in mode of operation for analog input on external pin.
+
+Contents of a stm32 adc child node:
+-----------------------------------
+An ADC block node should contain at least one subnode, representing an
+ADC instance available on the machine.
+
+Required properties:
+- compatible: Should be "st,stm32f4-adc".
+- reg: Offset of ADC instance in ADC block (e.g. may be 0x0, 0x100, 0x200).
+- clocks: Input clock private to this ADC instance.
+- interrupt-parent: Phandle to the parent interrupt controller.
+- interrupts: IRQ Line for the ADC (e.g. may be 0 for adc@0, 1 for adc@100 or
+  2 for adc@200).
+- st,adc-channels: List of single-ended channels muxed for this ADC.
+  It can have up to 16 channels, numbered from 0 to 15 (resp. for in0..in15).
+- #io-channel-cells = <1>: See the IIO bindings section "IIO consumers" in

+NVIDIA Tegra Hardware Synchronization Primitives (HSP)
+
+The HSP modules are used for the processors to share resources and communicate

+Optionally an altenative binding can be used if more suitable depending on the

+pin controller instances, naming each pin and function can easily become
+unmaintainable. This is especially the case if the same controller is used for
+different pins and functions depending on the SoC revision and packaging.
+
+For cases like this, the pin controller driver may use pinctrl-pin-array helper
+binding with a hardware based index and a number of pin configuration values:
+
+pincontroller {
+	... /* Standard DT properties for the device itself elided */
+	#pinctrl-cells = <2>;

+
+Above #pinctrl-cells specifies the number of value cells in addition to the
+index of the registers. This is similar to the interrupts-extended binding with
+one exception. There is no need to specify the phandle for each entry as that
+is already known as the defined pins are always children of the pin controller
+node. Further having the phandle pointing to another pin controller would not
+currently work as the pinctrl framework uses named modes to group pins for each
+pin control device.
+
+The index for pinctrl-pin-array must relate to the hardware for the pinctrl
+registers, and must not be a virtual index of pin instances. The reason for
+this is to avoid mapping of the index in the dts files and the pin controller
+driver as it can change.

+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.

+
+The 'loop1' gpio pin controlls two relays, which are either in loop position,
+meaning that input and output are directly connected, or they are in mixer
+position, meaning that the signal is passed through the 'Sum' mixer. Similarly
+for 'loop2'.
+
+In the above, the 'loop1' relays are inactive, thus feeding IN1 to the mixer
+(if 'add' is active) and feeding the mixer output to OUT1. The 'loop2' relays
+are active, short-cutting the TSE-850 from channel 2. IN1, IN2, OUT1 and OUT2
+are TSE-850 connectors and DAC is the PCB name of the (filtered) output from
+the PCM5142 codec.

+DocBook XML [DEPRECATED]
+========================
+
+.. attention::
+
+   This section describes the deprecated DocBook XML toolchain. Please do not
+   create new DocBook XML template files. Please consider converting existing
+   DocBook XML templates files to Sphinx/reStructuredText.
+
+Converting DocBook to Sphinx
+----------------------------
+
+Over time, we expect all of the documents under ``Documentation/DocBook`` to be
+converted to Sphinx and reStructuredText. For most DocBook XML documents, a good
+enough solution is to use the simple ``Documentation/sphinx/tmplcvt`` script,
+which uses ``pandoc`` under the hood. For example::
+
+  $ cd Documentation/sphinx
+  $ ./tmplcvt ../DocBook/in.tmpl ../out.rst
+
+Then edit the resulting rst files to fix any remaining issues, and add the
+document in the ``toctree`` in ``Documentation/index.rst``.
+
+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 reStructuredText, DocBook, man, text, and HTML. (No, not
+  texinfo.)
+
+- ``Documentation/DocBook/*.tmpl``
+
+  These are XML template files, which are normal XML files with special
+  place-holders for where the extracted documentation should go.
+
+- ``scripts/docproc.c``
+
+  This is a program for converting XML template files into XML 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 XML template files to locate all the files
+  referenced herein. This is used to generate dependency information as used by
+  make.
+
+- ``Makefile``
+
+  The targets 'xmldocs', 'psdocs', 'pdfdocs', and 'htmldocs' are used to build
+  DocBook XML files, PostScript files, PDF files, and html files in
+  Documentation/DocBook. The older target 'sgmldocs' is equivalent to 'xmldocs'.
+
+- ``Documentation/DocBook/Makefile``
+
+  This is where C files are associated with SGML templates.
+
+How to use kernel-doc comments in DocBook XML template files
+------------------------------------------------------------
+
+DocBook XML template files (\*.tmpl) are like normal XML files, except that they
+can contain escape sequences where extracted documentation should be inserted.
+
+``!E<filename>`` is replaced by the documentation, in ``<filename>``, for
+functions that are exported using ``EXPORT_SYMBOL``: the function list is
+collected from files listed in ``Documentation/DocBook/Makefile``.
+
+``!I<filename>`` is replaced by the documentation for functions that are **not**
+exported using ``EXPORT_SYMBOL``.
+
+``!D<filename>`` is used to name additional files to search for functions
+exported using ``EXPORT_SYMBOL``.
+
+``!F<filename> <function [functions...]>`` is replaced by the documentation, in
+``<filename>``, for the functions listed.
+
+``!P<filename> <section title>`` is replaced by the contents of the ``DOC:``
+section titled ``<section title>`` from ``<filename>``. Spaces are allowed in
+``<section title>``; do not quote the ``<section title>``.
+
+``!C<filename>`` is replaced by nothing, but makes the tools check that all DOC:
+sections and documented functions, symbols, etc. are used. This makes sense to
+use when you use ``!F`` or ``!P`` only and want to verify that all documentation
+is included.

-==========================
-Linux Kernel Documentation
-==========================
-
-Introduction
-============
-
-The Linux kernel uses `Sphinx`_ to generate pretty documentation from
-`reStructuredText`_ files under ``Documentation``. To build the documentation in
-HTML or PDF formats, use ``make htmldocs`` or ``make pdfdocs``. The generated
-documentation is placed in ``Documentation/output``.
-
-.. _Sphinx: http://www.sphinx-doc.org/
-.. _reStructuredText: http://docutils.sourceforge.net/rst.html
-
-The reStructuredText files may contain directives to include structured
-documentation comments, or kernel-doc comments, from source files. Usually these
-are used to describe the functions and types and design of the code. The
-kernel-doc comments have some special structure and formatting, but beyond that
-they are also treated as reStructuredText.
-
-There is also the deprecated DocBook toolchain to generate documentation from
-DocBook XML template files under ``Documentation/DocBook``. The DocBook files
-are to be converted to reStructuredText, and the toolchain is slated to be
-removed.
-
-Finally, there are thousands of plain text documentation files scattered around
-``Documentation``. Some of these will likely be converted to reStructuredText
-over time, but the bulk of them will remain in plain text.
-
-Sphinx Build
-============
-
-The usual way to generate the documentation is to run ``make htmldocs`` or
-``make pdfdocs``. There are also other formats available, see the documentation
-section of ``make help``. The generated documentation is placed in
-format-specific subdirectories under ``Documentation/output``.
-
-To generate documentation, Sphinx (``sphinx-build``) must obviously be
-installed. For prettier HTML output, the Read the Docs Sphinx theme
-(``sphinx_rtd_theme``) is used if available. For PDF output, ``rst2pdf`` is also
-needed. All of these are widely available and packaged in distributions.
-
-To pass extra options to Sphinx, you can use the ``SPHINXOPTS`` make
-variable. For example, use ``make SPHINXOPTS=-v htmldocs`` to get more verbose
-output.
-
-To remove the generated documentation, run ``make cleandocs``.
-
-Writing Documentation
-=====================
-
-Adding new documentation can be as simple as:
-
-1. Add a new ``.rst`` file somewhere under ``Documentation``.
-2. Refer to it from the Sphinx main `TOC tree`_ in ``Documentation/index.rst``.
-
-.. _TOC tree: http://www.sphinx-doc.org/en/stable/markup/toctree.html
-
-This is usually good enough for simple documentation (like the one you're
-reading right now), but for larger documents it may be advisable to create a
-subdirectory (or use an existing one). For example, the graphics subsystem
-documentation is under ``Documentation/gpu``, split to several ``.rst`` files,
-and has a separate ``index.rst`` (with a ``toctree`` of its own) referenced from
-the main index.
-
-See the documentation for `Sphinx`_ and `reStructuredText`_ on what you can do
-with them. In particular, the Sphinx `reStructuredText Primer`_ is a good place
-to get started with reStructuredText. There are also some `Sphinx specific
-markup constructs`_.
-
-.. _reStructuredText Primer: http://www.sphinx-doc.org/en/stable/rest.html
-.. _Sphinx specific markup constructs: http://www.sphinx-doc.org/en/stable/markup/index.html
-
-Specific guidelines for the kernel documentation
-------------------------------------------------
-
-Here are some specific guidelines for the kernel documentation:
-
-* Please don't go overboard with reStructuredText markup. Keep it simple.
-
-* Please stick to this order of heading adornments:
-
-  1. ``=`` with overline for document title::
-
-       ==============
-       Document title
-       ==============
-
-  2. ``=`` for chapters::
-
-       Chapters
-       ========
-
-  3. ``-`` for sections::
-
-       Section
-       -------
-
-  4. ``~`` for subsections::
-
-       Subsection
-       ~~~~~~~~~~
-
-  Although RST doesn't mandate a specific order ("Rather than imposing a fixed
-  number and order of section title adornment styles, the order enforced will be
-  the order as encountered."), having the higher levels the same overall makes
-  it easier to follow the documents.
-
-
-the C domain
-------------
-
-The `Sphinx C Domain`_ (name c) is suited for documentation of C API. E.g. a
-function prototype:
-
-.. code-block:: rst
-
-    .. c:function:: int ioctl( int fd, int request )
-
-The C domain of the kernel-doc has some additional features. E.g. you can
-*rename* the reference name of a function with a common name like ``open`` or
-``ioctl``:
-
-.. code-block:: rst
-
-     .. c:function:: int ioctl( int fd, int request )
-        :name: VIDIOC_LOG_STATUS
-
-The func-name (e.g. ioctl) remains in the output but the ref-name changed from
-``ioctl`` to ``VIDIOC_LOG_STATUS``. The index entry for this function is also
-changed to ``VIDIOC_LOG_STATUS`` and the function can now referenced by:
-
-.. code-block:: rst
-
-     :c:func:`VIDIOC_LOG_STATUS`
-
-
-list tables
------------
-
-We recommend the use of *list table* formats. The *list table* formats are
-double-stage lists. Compared to the ASCII-art they might not be as
-comfortable for 
-readers of the text files. Their advantage is that they are easy to
-create or modify and that the diff of a modification is much more meaningful,
-because it is limited to the modified content.
-
-The ``flat-table`` is a double-stage list similar to the ``list-table`` with
-some additional features:
-
-* column-span: with the role ``cspan`` a cell can be extended through
-  additional columns
-
-* row-span: with the role ``rspan`` a cell can be extended through
-  additional rows
-
-* auto span rightmost cell of a table row over the missing cells on the right
-  side of that table-row.  With Option ``:fill-cells:`` this behavior can
-  changed from *auto span* to *auto fill*, which automatically inserts (empty)
-  cells instead of spanning the last cell.
-
-options:
-
-* ``:header-rows:``   [int] count of header rows
-* ``:stub-columns:``  [int] count of stub columns
-* ``:widths:``        [[int] [int] ... ] widths of columns
-* ``:fill-cells:``    instead of auto-spanning missing cells, insert missing cells
-
-roles:
-
-* ``:cspan:`` [int] additional columns (*morecols*)
-* ``:rspan:`` [int] additional rows (*morerows*)
-
-The example below shows how to use this markup.  The first level of the staged
-list is the *table-row*. In the *table-row* there is only one markup allowed,
-the list of the cells in this *table-row*. Exceptions are *comments* ( ``..`` )
-and *targets* (e.g. a ref to ``:ref:`last row <last row>``` / :ref:`last row
-<last row>`).

+DESCRIPTION
+***********
+
+
+Convert a C header or source file (C_FILE), into a ReStructured Text
+included via ..parsed-literal block with cross-references for the
+documentation files that describe the API. It accepts an optional
+EXCEPTIONS_FILE with describes what elements will be either ignored or
+be pointed to a non-default reference.
+
+The output is written at the (OUT_FILE).
+
+It is capable of identifying defines, functions, structs, typedefs,
+enums and enum symbols and create cross-references for all of them.
+It is also capable of distinguish #define used for specifying a Linux
+ioctl.
+
+The EXCEPTIONS_FILE contain two types of statements: \ **ignore**\  or \ **replace**\ .
+
+The syntax for the ignore tag is:
+
+
+ignore \ **type**\  \ **name**\
+
+The \ **ignore**\  means that it won't generate cross references for a
+\ **name**\  symbol of type \ **type**\ .
+
+The syntax for the replace tag is:
+
+
+replace \ **type**\  \ **name**\  \ **new_value**\
+
+The \ **replace**\  means that it will generate cross references for a
+\ **name**\  symbol of type \ **type**\ , but, instead of using the default
+replacement rule, it will use \ **new_value**\ .
+
+For both statements, \ **type**\  can be either one of the following:
+
+
+\ **ioctl**\
+
+ The ignore or replace statement will apply to ioctl definitions like:
+
+ #define	VIDIOC_DBG_S_REGISTER 	 _IOW('V', 79, struct v4l2_dbg_register)
+
+
+
+\ **define**\
+
+ The ignore or replace statement will apply to any other #define found
+ at C_FILE.
+
+
+
+\ **typedef**\
+
+ The ignore or replace statement will apply to typedef statements at C_FILE.
+
+
+
+\ **struct**\
+
+ The ignore or replace statement will apply to the name of struct statements
+ at C_FILE.
+
+
+
+\ **enum**\
+
+ The ignore or replace statement will apply to the name of enum statements
+ at C_FILE.
+
+
+
+\ **symbol**\
+
+ The ignore or replace statement will apply to the name of enum statements
+ at C_FILE.
+
+ For replace statements, \ **new_value**\  will automatically use :c:type:
+ references for \ **typedef**\ , \ **enum**\  and \ **struct**\  types. It will use :ref:
+ for \ **ioctl**\ , \ **define**\  and \ **symbol**\  types. The type of reference can
+ also be explicitly defined at the replace statement.
+
+
+
+EXAMPLES
+********
+
+
+ignore define _VIDEODEV2_H
+
+
+Ignore a #define _VIDEODEV2_H at the C_FILE.
+
+ignore symbol PRIVATE
+
+
+On a struct like:
+
+enum foo { BAR1, BAR2, PRIVATE };
+
+It won't generate cross-references for \ **PRIVATE**\ .
+
+replace symbol BAR1 :c:type:\`foo\`
+replace symbol BAR2 :c:type:\`foo\`
+
+
+On a struct like:
+
+enum foo { BAR1, BAR2, PRIVATE };
+
+It will make the BAR1 and BAR2 enum symbols to cross reference the foo
+symbol at the C domain.

+documentation is placed in ``Documentation/output``.
+
+.. _Sphinx: http://www.sphinx-doc.org/
+.. _reStructuredText: http://docutils.sourceforge.net/rst.html
+
+The reStructuredText files may contain directives to include structured
+documentation comments, or kernel-doc comments, from source files. Usually these
+are used to describe the functions and types and design of the code. The
+kernel-doc comments have some special structure and formatting, but beyond that
+they are also treated as reStructuredText.
+
+There is also the deprecated DocBook toolchain to generate documentation from
+DocBook XML template files under ``Documentation/DocBook``. The DocBook files
+are to be converted to reStructuredText, and the toolchain is slated to be
+removed.
+
+Finally, there are thousands of plain text documentation files scattered around
+``Documentation``. Some of these will likely be converted to reStructuredText
+over time, but the bulk of them will remain in plain text.
+
+Sphinx Build
+============
+
+The usual way to generate the documentation is to run ``make htmldocs`` or
+``make pdfdocs``. There are also other formats available, see the documentation
+section of ``make help``. The generated documentation is placed in
+format-specific subdirectories under ``Documentation/output``.
+
+To generate documentation, Sphinx (``sphinx-build``) must obviously be
+installed. For prettier HTML output, the Read the Docs Sphinx theme
+(``sphinx_rtd_theme``) is used if available. For PDF output, ``rst2pdf`` is also
+needed. All of these are widely available and packaged in distributions.
+
+To pass extra options to Sphinx, you can use the ``SPHINXOPTS`` make
+variable. For example, use ``make SPHINXOPTS=-v htmldocs`` to get more verbose
+output.
+
+To remove the generated documentation, run ``make cleandocs``.
+
+Writing Documentation
+=====================
+
+Adding new documentation can be as simple as:
+
+1. Add a new ``.rst`` file somewhere under ``Documentation``.
+2. Refer to it from the Sphinx main `TOC tree`_ in ``Documentation/index.rst``.
+
+.. _TOC tree: http://www.sphinx-doc.org/en/stable/markup/toctree.html
+
+This is usually good enough for simple documentation (like the one you're
+reading right now), but for larger documents it may be advisable to create a
+subdirectory (or use an existing one). For example, the graphics subsystem
+documentation is under ``Documentation/gpu``, split to several ``.rst`` files,
+and has a separate ``index.rst`` (with a ``toctree`` of its own) referenced from
+the main index.
+
+See the documentation for `Sphinx`_ and `reStructuredText`_ on what you can do
+with them. In particular, the Sphinx `reStructuredText Primer`_ is a good place
+to get started with reStructuredText. There are also some `Sphinx specific
+markup constructs`_.
+
+.. _reStructuredText Primer: http://www.sphinx-doc.org/en/stable/rest.html
+.. _Sphinx specific markup constructs: http://www.sphinx-doc.org/en/stable/markup/index.html
+
+Specific guidelines for the kernel documentation
+------------------------------------------------
+
+Here are some specific guidelines for the kernel documentation:
+
+* Please don't go overboard with reStructuredText markup. Keep it simple.
+
+* Please stick to this order of heading adornments:
+
+  1. ``=`` with overline for document title::
+
+       ==============
+       Document title
+       ==============
+
+  2. ``=`` for chapters::
+
+       Chapters
+       ========
+
+  3. ``-`` for sections::
+
+       Section
+       -------
+
+  4. ``~`` for subsections::
+
+       Subsection
+       ~~~~~~~~~~
+
+  Although RST doesn't mandate a specific order ("Rather than imposing a fixed
+  number and order of section title adornment styles, the order enforced will be
+  the order as encountered."), having the higher levels the same overall makes
+  it easier to follow the documents.
+
+
+the C domain
+------------
+
+The `Sphinx C Domain`_ (name c) is suited for documentation of C API. E.g. a
+function prototype:
+
+.. code-block:: rst
+
+    .. c:function:: int ioctl( int fd, int request )
+
+The C domain of the kernel-doc has some additional features. E.g. you can
+*rename* the reference name of a function with a common name like ``open`` or
+``ioctl``:
+
+.. code-block:: rst
+
+     .. c:function:: int ioctl( int fd, int request )
+        :name: VIDIOC_LOG_STATUS
+
+The func-name (e.g. ioctl) remains in the output but the ref-name changed from
+``ioctl`` to ``VIDIOC_LOG_STATUS``. The index entry for this function is also
+changed to ``VIDIOC_LOG_STATUS`` and the function can now referenced by:
+
+.. code-block:: rst
+
+     :c:func:`VIDIOC_LOG_STATUS`
+
+
+list tables
+-----------
+
+We recommend the use of *list table* formats. The *list table* formats are
+double-stage lists. Compared to the ASCII-art they might not be as
+comfortable for
+readers of the text files. Their advantage is that they are easy to
+create or modify and that the diff of a modification is much more meaningful,
+because it is limited to the modified content.
+
+The ``flat-table`` is a double-stage list similar to the ``list-table`` with
+some additional features:
+
+* column-span: with the role ``cspan`` a cell can be extended through
+  additional columns
+
+* row-span: with the role ``rspan`` a cell can be extended through
+  additional rows
+
+* auto span rightmost cell of a table row over the missing cells on the right
+  side of that table-row.  With Option ``:fill-cells:`` this behavior can
+  changed from *auto span* to *auto fill*, which automatically inserts (empty)
+  cells instead of spanning the last cell.
+
+options:
+
+* ``:header-rows:``   [int] count of header rows
+* ``:stub-columns:``  [int] count of stub columns
+* ``:widths:``        [[int] [int] ... ] widths of columns
+* ``:fill-cells:``    instead of auto-spanning missing cells, insert missing cells
+
+roles:
+
+* ``:cspan:`` [int] additional columns (*morecols*)
+* ``:rspan:`` [int] additional rows (*morerows*)
+
+The example below shows how to use this markup.  The first level of the staged
+list is the *table-row*. In the *table-row* there is only one markup allowed,
+the list of the cells in this *table-row*. Exceptions are *comments* ( ``..`` )
+and *targets* (e.g. a ref to ``:ref:`last row <last row>``` / :ref:`last row
+<last row>`).
+
+.. code-block:: rst
+
+   .. flat-table:: table title
+      :widths: 2 1 1 3
+
+      * - head col 1
+        - head col 2

+
+      * .. _`last row`:
+
+        - column 3

+Device links
+============
+
+By default, the driver core only enforces dependencies between devices
+that are borne out of a parent/child relationship within the device
+hierarchy: When suspending, resuming or shutting down the system, devices
+are ordered based on this relationship, i.e. children are always suspended
+before their parent, and the parent is always resumed before its children.
+
+Sometimes there is a need to represent device dependencies beyond the
+mere parent/child relationship, e.g. between siblings, and have the
+driver core automatically take care of them.
+
+Secondly, the driver core by default does not enforce any driver presence
+dependencies, i.e. that one device must be bound to a driver before
+another one can probe or function correctly.
+
+Often these two dependency types come together, so a device depends on
+another one both with regards to driver presence *and* with regards to
+suspend/resume and shutdown ordering.
+
+Device links allow representation of such dependencies in the driver core.
+
+In its standard form, a device link combines *both* dependency types:
+It guarantees correct suspend/resume and shutdown ordering between a
+"supplier" device and its "consumer" devices, and it guarantees driver
+presence on the supplier.  The consumer devices are not probed before the
+supplier is bound to a driver, and they're unbound before the supplier
+is unbound.
+
+When driver presence on the supplier is irrelevant and only correct
+suspend/resume and shutdown ordering is needed, the device link may
+simply be set up with the ``DL_FLAG_STATELESS`` flag.  In other words,
+enforcing driver presence on the supplier is optional.
+
+Another optional feature is runtime PM integration:  By setting the
+``DL_FLAG_PM_RUNTIME`` flag on addition of the device link, the PM core
+is instructed to runtime resume the supplier and keep it active
+whenever and for as long as the consumer is runtime resumed.
+
+Usage
+=====
+
+The earliest point in time when device links can be added is after
+:c:func:`device_add()` has been called for the supplier and
+:c:func:`device_initialize()` has been called for the consumer.
+
+It is legal to add them later, but care must be taken that the system
+remains in a consistent state:  E.g. a device link cannot be added in
+the midst of a suspend/resume transition, so either commencement of
+such a transition needs to be prevented with :c:func:`lock_system_sleep()`,
+or the device link needs to be added from a function which is guaranteed
+not to run in parallel to a suspend/resume transition, such as from a
+device ``->probe`` callback or a boot-time PCI quirk.
+
+Another example for an inconsistent state would be a device link that
+represents a driver presence dependency, yet is added from the consumer's
+``->probe`` callback while the supplier hasn't probed yet:  Had the driver
+core known about the device link earlier, it wouldn't have probed the
+consumer in the first place.  The onus is thus on the consumer to check
+presence of the supplier after adding the link, and defer probing on
+non-presence.
+
+If a device link is added in the ``->probe`` callback of the supplier or
+consumer driver, it is typically deleted in its ``->remove`` callback for
+symmetry.  That way, if the driver is compiled as a module, the device
+link is added on module load and orderly deleted on unload.  The same
+restrictions that apply to device link addition (e.g. exclusion of a
+parallel suspend/resume transition) apply equally to deletion.
+
+Several flags may be specified on device link addition, two of which
+have already been mentioned above:  ``DL_FLAG_STATELESS`` to express that no
+driver presence dependency is needed (but only correct suspend/resume and
+shutdown ordering) and ``DL_FLAG_PM_RUNTIME`` to express that runtime PM
+integration is desired.
+
+Two other flags are specifically targeted at use cases where the device
+link is added from the consumer's ``->probe`` callback:  ``DL_FLAG_RPM_ACTIVE``
+can be specified to runtime resume the supplier upon addition of the
+device link.  ``DL_FLAG_AUTOREMOVE`` causes the device link to be automatically
+purged when the consumer fails to probe or later unbinds.  This obviates
+the need to explicitly delete the link in the ``->remove`` callback or in
+the error path of the ``->probe`` callback.
+
+Limitations
+===========
+
+Driver authors should be aware that a driver presence dependency (i.e. when
+``DL_FLAG_STATELESS`` is not specified on link addition) may cause probing of
+the consumer to be deferred indefinitely.  This can become a problem if the
+consumer is required to probe before a certain initcall level is reached.
+Worse, if the supplier driver is blacklisted or missing, the consumer will
+never be probed.
+
+Sometimes drivers depend on optional resources.  They are able to operate
+in a degraded mode (reduced feature set or performance) when those resources
+are not present.  An example is an SPI controller that can use a DMA engine
+or work in PIO mode.  The controller can determine presence of the optional
+resources at probe time but on non-presence there is no way to know whether
+they will become available in the near future (due to a supplier driver
+probing) or never.  Consequently it cannot be determined whether to defer
+probing or not.  It would be possible to notify drivers when optional
+resources become available after probing, but it would come at a high cost
+for drivers as switching between modes of operation at runtime based on the
+availability of such resources would be much more complex than a mechanism
+based on probe deferral.  In any case optional resources are beyond the
+scope of device links.
+
+Examples
+========
+
+* An MMU device exists alongside a busmaster device, both are in the same
+  power domain.  The MMU implements DMA address translation for the busmaster
+  device and shall be runtime resumed and kept active whenever and as long
+  as the busmaster device is active.  The busmaster device's driver shall
+  not bind before the MMU is bound.  To achieve this, a device link with
+  runtime PM integration is added from the busmaster device (consumer)
+  to the MMU device (supplier).  The effect with regards to runtime PM
+  is the same as if the MMU was the parent of the master device.
+
+  The fact that both devices share the same power domain would normally
+  suggest usage of a :c:type:`struct dev_pm_domain` or :c:type:`struct
+  generic_pm_domain`, however these are not independent devices that
+  happen to share a power switch, but rather the MMU device serves the
+  busmaster device and is useless without it.  A device link creates a
+  synthetic hierarchical relationship between the devices and is thus
+  more apt.
+
+* A Thunderbolt host controller comprises a number of PCIe hotplug ports
+  and an NHI device to manage the PCIe switch.  On resume from system sleep,
+  the NHI device needs to re-establish PCI tunnels to attached devices
+  before the hotplug ports can resume.  If the hotplug ports were children
+  of the NHI, this resume order would automatically be enforced by the
+  PM core, but unfortunately they're aunts.  The solution is to add
+  device links from the hotplug ports (consumers) to the NHI device
+  (supplier).  A driver presence dependency is not necessary for this
+  use case.
+
+* Discrete GPUs in hybrid graphics laptops often feature an HDA controller
+  for HDMI/DP audio.  In the device hierarchy the HDA controller is a sibling
+  of the VGA device, yet both share the same power domain and the HDA
+  controller is only ever needed when an HDMI/DP display is attached to the
+  VGA device.  A device link from the HDA controller (consumer) to the
+  VGA device (supplier) aptly represents this relationship.
+
+* ACPI allows definition of a device start order by way of _DEP objects.
+  A classical example is when ACPI power management methods on one device
+  are implemented in terms of I\ :sup:`2`\ C accesses and require a specific
+  I\ :sup:`2`\ C controller to be present and functional for the power
+  management of the device in question to work.
+
+* In some SoCs a functional dependency exists from display, video codec and
+  video processing IP cores on transparent memory access IP cores that handle
+  burst access and compression/decompression.
+
+Alternatives
+============
+
+* A :c:type:`struct dev_pm_domain` can be used to override the bus,
+  class or device type callbacks.  It is intended for devices sharing
+  a single on/off switch, however it does not guarantee a specific
+  suspend/resume ordering, this needs to be implemented separately.
+  It also does not by itself track the runtime PM status of the involved
+  devices and turn off the power switch only when all of them are runtime
+  suspended.  Furthermore it cannot be used to enforce a specific shutdown
+  ordering or a driver presence dependency.
+
+* A :c:type:`struct generic_pm_domain` is a lot more heavyweight than a
+  device link and does not allow for shutdown ordering or driver presence
+  dependencies.  It also cannot be used on ACPI systems.
+
+Implementation
+==============
+
+The device hierarchy, which -- as the name implies -- is a tree,
+becomes a directed acyclic graph once device links are added.
+
+Ordering of these devices during suspend/resume is determined by the
+dpm_list.  During shutdown it is determined by the devices_kset.  With
+no device links present, the two lists are a flattened, one-dimensional
+representations of the device tree such that a device is placed behind
+all its ancestors.  That is achieved by traversing the ACPI namespace
+or OpenFirmware device tree top-down and appending devices to the lists
+as they are discovered.
+
+Once device links are added, the lists need to satisfy the additional
+constraint that a device is placed behind all its suppliers, recursively.
+To ensure this, upon addition of the device link the consumer and the
+entire sub-graph below it (all children and consumers of the consumer)
+are moved to the end of the list.  (Call to :c:func:`device_reorder_to_tail()`
+from :c:func:`device_link_add()`.)
+
+To prevent introduction of dependency loops into the graph, it is
+verified upon device link addition that the supplier is not dependent
+on the consumer or any children or consumers of the consumer.
+(Call to :c:func:`device_is_dependent()` from :c:func:`device_link_add()`.)
+If that constraint is violated, :c:func:`device_link_add()` will return
+``NULL`` and a ``WARNING`` will be logged.
+
+Notably this also prevents the addition of a device link from a parent
+device to a child.  However the converse is allowed, i.e. a device link
+from a child to a parent.  Since the driver core already guarantees
+correct suspend/resume and shutdown ordering between parent and child,
+such a device link only makes sense if a driver presence dependency is
+needed on top of that.  In this case driver authors should weigh
+carefully if a device link is at all the right tool for the purpose.
+A more suitable approach might be to simply use deferred probing or
+add a device flag causing the parent driver to be probed before the
+child one.

+Buffer Sharing and Synchronization
+==================================
+
+The dma-buf subsystem provides the framework for sharing buffers for
+hardware (DMA) access across multiple device drivers and subsystems, and
+for synchronizing asynchronous hardware access.
+
+This is used, for example, by drm "prime" multi-GPU support, but is of

+The three main components of this are: (1) dma-buf, representing a

+between devices, (2) fence, which provides a mechanism to signal when

+Error Detection And Correction (EDAC) Devices
+=============================================
+
+Main Concepts used at the EDAC subsystem
+----------------------------------------
+
+There are several things to be aware of that aren't at all obvious, like
+*sockets, *socket sets*, *banks*, *rows*, *chip-select rows*, *channels*,
+etc...
+
+These are some of the many terms that are thrown about that don't always
+mean what people think they mean (Inconceivable!).  In the interest of
+creating a common ground for discussion, terms and their definitions
+will be established.
+
+* Memory devices
+
+The individual DRAM chips on a memory stick.  These devices commonly
+output 4 and 8 bits each (x4, x8). Grouping several of these in parallel
+provides the number of bits that the memory controller expects:
+typically 72 bits, in order to provide 64 bits + 8 bits of ECC data.
+
+* Memory Stick
+
+A printed circuit board that aggregates multiple memory devices in
+parallel.  In general, this is the Field Replaceable Unit (FRU) which
+gets replaced, in the case of excessive errors. Most often it is also
+called DIMM (Dual Inline Memory Module).
+
+* Memory Socket
+
+A physical connector on the motherboard that accepts a single memory
+stick. Also called as "slot" on several datasheets.
+
+* Channel
+
+A memory controller channel, responsible to communicate with a group of
+DIMMs. Each channel has its own independent control (command) and data
+bus, and can be used independently or grouped with other channels.
+
+* Branch
+
+It is typically the highest hierarchy on a Fully-Buffered DIMM memory
+controller. Typically, it contains two channels. Two channels at the
+same branch can be used in single mode or in lockstep mode. When
+lockstep is enabled, the cacheline is doubled, but it generally brings
+some performance penalty. Also, it is generally not possible to point to
+just one memory stick when an error occurs, as the error correction code
+is calculated using two DIMMs instead of one. Due to that, it is capable
+of correcting more errors than on single mode.
+
+* Single-channel
+
+The data accessed by the memory controller is contained into one dimm
+only. E. g. if the data is 64 bits-wide, the data flows to the CPU using
+one 64 bits parallel access. Typically used with SDR, DDR, DDR2 and DDR3
+memories. FB-DIMM and RAMBUS use a different concept for channel, so
+this concept doesn't apply there.
+
+* Double-channel
+
+The data size accessed by the memory controller is interlaced into two
+dimms, accessed at the same time. E. g. if the DIMM is 64 bits-wide (72
+bits with ECC), the data flows to the CPU using a 128 bits parallel
+access.
+
+* Chip-select row
+
+This is the name of the DRAM signal used to select the DRAM ranks to be
+accessed. Common chip-select rows for single channel are 64 bits, for
+dual channel 128 bits. It may not be visible by the memory controller,
+as some DIMM types have a memory buffer that can hide direct access to
+it from the Memory Controller.
+
+* Single-Ranked stick
+
+A Single-ranked stick has 1 chip-select row of memory. Motherboards
+commonly drive two chip-select pins to a memory stick. A single-ranked
+stick, will occupy only one of those rows. The other will be unused.
+
+.. _doubleranked:
+
+* Double-Ranked stick
+
+A double-ranked stick has two chip-select rows which access different
+sets of memory devices.  The two rows cannot be accessed concurrently.
+
+* Double-sided stick
+
+**DEPRECATED TERM**, see :ref:`Double-Ranked stick <doubleranked>`.
+
+A double-sided stick has two chip-select rows which access different sets
+of memory devices. The two rows cannot be accessed concurrently.
+"Double-sided" is irrespective of the memory devices being mounted on
+both sides of the memory stick.
+
+* Socket set
+
+All of the memory sticks that are required for a single memory access or
+all of the memory sticks spanned by a chip-select row.  A single socket
+set has two chip-select rows and if double-sided sticks are used these
+will occupy those chip-select rows.
+
+* Bank
+
+This term is avoided because it is unclear when needing to distinguish
+between chip-select rows and socket sets.
+
+
+Memory Controllers
+------------------
+
+Most of the EDAC core is focused on doing Memory Controller error detection.
+The :c:func:`edac_mc_alloc`. It uses internally the struct ``mem_ctl_info``
+to describe the memory controllers, with is an opaque struct for the EDAC
+drivers. Only the EDAC core is allowed to touch it.
+
+.. kernel-doc:: include/linux/edac.h
+
+.. kernel-doc:: drivers/edac/edac_mc.h
+
+PCI Controllers
+---------------
+
+The EDAC subsystem provides a mechanism to handle PCI controllers by calling
+the :c:func:`edac_pci_alloc_ctl_info`. It will use the struct
+:c:type:`edac_pci_ctl_info` to describe the PCI controllers.
+
+.. kernel-doc:: drivers/edac/edac_pci.h
+
+EDAC Blocks
+-----------
+
+The EDAC subsystem also provides a generic mechanism to report errors on
+other parts of the hardware via :c:func:`edac_device_alloc_ctl_info` function.
+
+The structures :c:type:`edac_dev_sysfs_block_attribute`,
+:c:type:`edac_device_block`, :c:type:`edac_device_instance` and
+:c:type:`edac_device_ctl_info` provide a generic or abstract 'edac_device'
+representation at sysfs.
+
+This set of structures and the code that implements the APIs for the same, provide for registering EDAC type devices which are NOT standard memory or
+PCI, like:
+
+- CPU caches (L1 and L2)
+- DMA engines
+- Core CPU switches
+- Fabric switch units
+- PCIe interface controllers
+- other EDAC/ECC type devices that can be monitored for
+  errors, etc.
+
+It allows for a 2 level set of hierarchy.
+
+For example, a cache could be composed of L1, L2 and L3 levels of cache.
+Each CPU core would have its own L1 cache, while sharing L2 and maybe L3
+caches. On such case, those can be represented via the following sysfs
+nodes::
+
+	/sys/devices/system/edac/..
+
+	pci/		<existing pci directory (if available)>
+	mc/		<existing memory device directory>
+	cpu/cpu0/..	<L1 and L2 block directory>
+		/L1-cache/ce_count
+			 /ue_count
+		/L2-cache/ce_count
+			 /ue_count
+	cpu/cpu1/..	<L1 and L2 block directory>
+		/L1-cache/ce_count
+			 /ue_count
+		/L2-cache/ce_count
+			 /ue_count
+	...
+
+	the L1 and L2 directories would be "edac_device_block's"

+===========================
+The Linux-USB Host Side API
+===========================
+
+Introduction to USB on Linux
+============================
+
+A Universal Serial Bus (USB) is used to connect a host, such as a PC or
+workstation, to a number of peripheral devices. USB uses a tree
+structure, with the host as the root (the system's master), hubs as
+interior nodes, and peripherals as leaves (and slaves). Modern PCs
+support several such trees of USB devices, usually
+a few USB 3.0 (5 GBit/s) or USB 3.1 (10 GBit/s) and some legacy
+USB 2.0 (480 MBit/s) busses just in case.
+
+That master/slave asymmetry was designed-in for a number of reasons, one
+being ease of use. It is not physically possible to mistake upstream and
+downstream or it does not matter with a type C plug (or they are built into the
+peripheral). Also, the host software doesn't need to deal with
+distributed auto-configuration since the pre-designated master node
+manages all that.
+
+Kernel developers added USB support to Linux early in the 2.2 kernel
+series and have been developing it further since then. Besides support
+for each new generation of USB, various host controllers gained support,
+new drivers for peripherals have been added and advanced features for latency
+measurement and improved power management introduced.
+
+Linux can run inside USB devices as well as on the hosts that control
+the devices. But USB device drivers running inside those peripherals
+don't do the same things as the ones running inside hosts, so they've
+been given a different name: *gadget drivers*. This document does not
+cover gadget drivers.
+
+USB Host-Side API Model
+=======================
+
+Host-side drivers for USB devices talk to the "usbcore" APIs. There are
+two. One is intended for *general-purpose* drivers (exposed through
+driver frameworks), and the other is for drivers that are *part of the
+core*. Such core drivers include the *hub* driver (which manages trees
+of USB devices) and several different kinds of *host controller
+drivers*, which control individual busses.
+
+The device model seen by USB drivers is relatively complex.
+
+-  USB supports four kinds of data transfers (control, bulk, interrupt,
+   and isochronous). Two of them (control and bulk) use bandwidth as
+   it's available, while the other two (interrupt and isochronous) are
+   scheduled to provide guaranteed bandwidth.
+
+-  The device description model includes one or more "configurations"
+   per device, only one of which is active at a time. Devices are supposed
+   to be capable of operating at lower than their top
+   speeds and may provide a BOS descriptor showing the lowest speed they
+   remain fully operational at.
+
+-  From USB 3.0 on configurations have one or more "functions", which
+   provide a common functionality and are grouped together for purposes
+   of power management.
+
+-  Configurations or functions have one or more "interfaces", each of which may have
+   "alternate settings". Interfaces may be standardized by USB "Class"
+   specifications, or may be specific to a vendor or device.
+
+   USB device drivers actually bind to interfaces, not devices. Think of
+   them as "interface drivers", though you may not see many devices
+   where the distinction is important. *Most USB devices are simple,
+   with only one function, one configuration, one interface, and one alternate
+   setting.*
+
+-  Interfaces have one or more "endpoints", each of which supports one
+   type and direction of data transfer such as "bulk out" or "interrupt
+   in". The entire configuration may have up to sixteen endpoints in
+   each direction, allocated as needed among all the interfaces.
+
+-  Data transfer on USB is packetized; each endpoint has a maximum
+   packet size. Drivers must often be aware of conventions such as
+   flagging the end of bulk transfers using "short" (including zero
+   length) packets.
+
+-  The Linux USB API supports synchronous calls for control and bulk
+   messages. It also supports asynchronous calls for all kinds of data
+   transfer, using request structures called "URBs" (USB Request
+   Blocks).
+
+Accordingly, the USB Core API exposed to device drivers covers quite a
+lot of territory. You'll probably need to consult the USB 3.0
+specification, available online from www.usb.org at no cost, as well as
+class or device specifications.
+
+The only host-side drivers that actually touch hardware (reading/writing
+registers, handling IRQs, and so on) are the HCDs. In theory, all HCDs
+provide the same functionality through the same API. In practice, that's
+becoming more true, but there are still differences
+that crop up especially with fault handling on the less common controllers.
+Different controllers don't
+necessarily report the same aspects of failures, and recovery from
+faults (including software-induced ones like unlinking an URB) isn't yet
+fully consistent. Device driver authors should make a point of doing
+disconnect testing (while the device is active) with each different host
+controller driver, to make sure drivers don't have bugs of their own as
+well as to make sure they aren't relying on some HCD-specific behavior.
+
+USB-Standard Types
+==================
+
+In ``<linux/usb/ch9.h>`` you will find the USB data types defined in
+chapter 9 of the USB specification. These data types are used throughout
+USB, and in APIs including this host side API, gadget APIs, and usbfs.
+
+.. kernel-doc:: include/linux/usb/ch9.h
+   :internal:
+
+Host-Side Data Types and Macros
+===============================
+
+The host side API exposes several layers to drivers, some of which are
+more necessary than others. These support lifecycle models for host side
+drivers and devices, and support passing buffers through usbcore to some
+HCD that performs the I/O for the device driver.
+
+.. kernel-doc:: include/linux/usb.h
+   :internal:
+
+USB Core APIs
+=============
+
+There are two basic I/O models in the USB API. The most elemental one is
+asynchronous: drivers submit requests in the form of an URB, and the
+URB's completion callback handles the next step. All USB transfer types
+support that model, although there are special cases for control URBs
+(which always have setup and status stages, but may not have a data
+stage) and isochronous URBs (which allow large packets and include
+per-packet fault reports). Built on top of that is synchronous API
+support, where a driver calls a routine that allocates one or more URBs,
+submits them, and waits until they complete. There are synchronous
+wrappers for single-buffer control and bulk transfers (which are awkward
+to use in some driver disconnect scenarios), and for scatterlist based
+streaming i/o (bulk or interrupt).
+
+USB drivers need to provide buffers that can be used for DMA, although
+they don't necessarily need to provide the DMA mapping themselves. There
+are APIs to use used when allocating DMA buffers, which can prevent use
+of bounce buffers on some systems. In some cases, drivers may be able to
+rely on 64bit DMA to eliminate another kind of bounce buffer.

+
+Host Controller APIs
+====================
+
+These APIs are only for use by host controller drivers, most of which
+implement standard register interfaces such as XHCI, EHCI, OHCI, or UHCI. UHCI
+was one of the first interfaces, designed by Intel and also used by VIA;
+it doesn't do much in hardware. OHCI was designed later, to have the
+hardware do more work (bigger transfers, tracking protocol state, and so
+on). EHCI was designed with USB 2.0; its design has features that
+resemble OHCI (hardware does much more work) as well as UHCI (some parts
+of ISO support, TD list processing). XHCI was designed with USB 3.0. It
+continues to shift support for functionality into hardware.
+
+There are host controllers other than the "big three", although most PCI
+based controllers (and a few non-PCI based ones) use one of those
+interfaces. Not all host controllers use DMA; some use PIO, and there is
+also a simulator and a virtual host controller to pipe USB over the network.
+
+The same basic APIs are available to drivers for all those controllers.
+For historical reasons they are in two layers: :c:type:`struct
+usb_bus <usb_bus>` is a rather thin layer that became available
+in the 2.2 kernels, while :c:type:`struct usb_hcd <usb_hcd>`
+is a more featureful layer
+that lets HCDs share common code, to shrink driver size and
+significantly reduce hcd-specific behaviors.

+
+The USB Filesystem (usbfs)
+==========================
+
+This chapter presents the Linux *usbfs*. You may prefer to avoid writing
+new kernel code for your USB driver; that's the problem that usbfs set
+out to solve. User mode device drivers are usually packaged as
+applications or libraries, and may use usbfs through some programming
+library that wraps it. Such libraries include
+`libusb <http://libusb.sourceforge.net>`__ for C/C++, and
+`jUSB <http://jUSB.sourceforge.net>`__ for Java.
+
+    **Note**
+
+    This particular documentation is incomplete, especially with respect
+    to the asynchronous mode. As of kernel 2.5.66 the code and this
+    (new) documentation need to be cross-reviewed.
+
+Configure usbfs into Linux kernels by enabling the *USB filesystem*
+option (CONFIG_USB_DEVICEFS), and you get basic support for user mode
+USB device drivers. Until relatively recently it was often (confusingly)
+called *usbdevfs* although it wasn't solving what *devfs* was. Every USB
+device will appear in usbfs, regardless of whether or not it has a
+kernel driver.
+
+What files are in "usbfs"?
+--------------------------
+
+Conventionally mounted at ``/proc/bus/usb``, usbfs features include:
+
+-  ``/proc/bus/usb/devices`` ... a text file showing each of the USB
+   devices on known to the kernel, and their configuration descriptors.
+   You can also poll() this to learn about new devices.
+
+-  ``/proc/bus/usb/BBB/DDD`` ... magic files exposing the each device's
+   configuration descriptors, and supporting a series of ioctls for
+   making device requests, including I/O to devices. (Purely for access
+   by programs.)
+
+Each bus is given a number (BBB) based on when it was enumerated; within
+each bus, each device is given a similar number (DDD). Those BBB/DDD
+paths are not "stable" identifiers; expect them to change even if you
+always leave the devices plugged in to the same hub port. *Don't even
+think of saving these in application configuration files.* Stable
+identifiers are available, for user mode applications that want to use
+them. HID and networking devices expose these stable IDs, so that for
+example you can be sure that you told the right UPS to power down its
+second server. "usbfs" doesn't (yet) expose those IDs.
+
+Mounting and Access Control
+---------------------------
+
+There are a number of mount options for usbfs, which will be of most
+interest to you if you need to override the default access control
+policy. That policy is that only root may read or write device files
+(``/proc/bus/BBB/DDD``) although anyone may read the ``devices`` or
+``drivers`` files. I/O requests to the device also need the
+CAP_SYS_RAWIO capability,
+
+The significance of that is that by default, all user mode device
+drivers need super-user privileges. You can change modes or ownership in
+a driver setup when the device hotplugs, or maye just start the driver
+right then, as a privileged server (or some activity within one). That's
+the most secure approach for multi-user systems, but for single user
+systems ("trusted" by that user) it's more convenient just to grant
+everyone all access (using the *devmode=0666* option) so the driver can
+start whenever it's needed.
+
+The mount options for usbfs, usable in /etc/fstab or in command line
+invocations of *mount*, are:
+
+*busgid*\ =NNNNN
+    Controls the GID used for the /proc/bus/usb/BBB directories.
+    (Default: 0)
+
+*busmode*\ =MMM
+    Controls the file mode used for the /proc/bus/usb/BBB directories.
+    (Default: 0555)
+
+*busuid*\ =NNNNN
+    Controls the UID used for the /proc/bus/usb/BBB directories.
+    (Default: 0)
+
+*devgid*\ =NNNNN
+    Controls the GID used for the /proc/bus/usb/BBB/DDD files. (Default:
+    0)
+
+*devmode*\ =MMM
+    Controls the file mode used for the /proc/bus/usb/BBB/DDD files.
+    (Default: 0644)
+
+*devuid*\ =NNNNN
+    Controls the UID used for the /proc/bus/usb/BBB/DDD files. (Default:
+    0)
+
+*listgid*\ =NNNNN
+    Controls the GID used for the /proc/bus/usb/devices and drivers
+    files. (Default: 0)
+
+*listmode*\ =MMM
+    Controls the file mode used for the /proc/bus/usb/devices and
+    drivers files. (Default: 0444)
+
+*listuid*\ =NNNNN
+    Controls the UID used for the /proc/bus/usb/devices and drivers
+    files. (Default: 0)
+
+Note that many Linux distributions hard-wire the mount options for usbfs
+in their init scripts, such as ``/etc/rc.d/rc.sysinit``, rather than
+making it easy to set this per-system policy in ``/etc/fstab``.
+
+/proc/bus/usb/devices
+---------------------
+
+This file is handy for status viewing tools in user mode, which can scan
+the text format and ignore most of it. More detailed device status
+(including class and vendor status) is available from device-specific
+files. For information about the current format of this file, see the
+``Documentation/usb/proc_usb_info.txt`` file in your Linux kernel
+sources.
+
+This file, in combination with the poll() system call, can also be used
+to detect when devices are added or removed:
+
+::
+
+    int fd;
+    struct pollfd pfd;
+
+    fd = open("/proc/bus/usb/devices", O_RDONLY);
+    pfd = { fd, POLLIN, 0 };
+    for (;;) {
+        /* The first time through, this call will return immediately. */
+        poll(&pfd, 1, -1);
+
+        /* To see what's changed, compare the file's previous and current
+           contents or scan the filesystem.  (Scanning is more precise.) */
+    }
+
+Note that this behavior is intended to be used for informational and
+debug purposes. It would be more appropriate to use programs such as
+udev or HAL to initialize a device or start a user-mode helper program,
+for instance.
+
+/proc/bus/usb/BBB/DDD
+---------------------
+
+Use these files in one of these basic ways:
+
+*They can be read,* producing first the device descriptor (18 bytes) and
+then the descriptors for the current configuration. See the USB 2.0 spec
+for details about those binary data formats. You'll need to convert most
+multibyte values from little endian format to your native host byte
+order, although a few of the fields in the device descriptor (both of
+the BCD-encoded fields, and the vendor and product IDs) will be
+byteswapped for you. Note that configuration descriptors include
+descriptors for interfaces, altsettings, endpoints, and maybe additional
+class descriptors.
+
+*Perform USB operations* using *ioctl()* requests to make endpoint I/O
+requests (synchronously or asynchronously) or manage the device. These
+requests need the CAP_SYS_RAWIO capability, as well as filesystem
+access permissions. Only one ioctl request can be made on one of these
+device files at a time. This means that if you are synchronously reading
+an endpoint from one thread, you won't be able to write to a different
+endpoint from another thread until the read completes. This works for
+*half duplex* protocols, but otherwise you'd use asynchronous i/o
+requests.
+
+Life Cycle of User Mode Drivers
+-------------------------------
+
+Such a driver first needs to find a device file for a device it knows
+how to handle. Maybe it was told about it because a ``/sbin/hotplug``
+event handling agent chose that driver to handle the new device. Or
+maybe it's an application that scans all the /proc/bus/usb device files,
+and ignores most devices. In either case, it should :c:func:`read()`
+all the descriptors from the device file, and check them against what it
+knows how to handle. It might just reject everything except a particular
+vendor and product ID, or need a more complex policy.
+
+Never assume there will only be one such device on the system at a time!
+If your code can't handle more than one device at a time, at least
+detect when there's more than one, and have your users choose which
+device to use.
+
+Once your user mode driver knows what device to use, it interacts with
+it in either of two styles. The simple style is to make only control
+requests; some devices don't need more complex interactions than those.
+(An example might be software using vendor-specific control requests for
+some initialization or configuration tasks, with a kernel driver for the
+rest.)
+
+More likely, you need a more complex style driver: one using non-control
+endpoints, reading or writing data and claiming exclusive use of an
+interface. *Bulk* transfers are easiest to use, but only their sibling
+*interrupt* transfers work with low speed devices. Both interrupt and
+*isochronous* transfers offer service guarantees because their bandwidth
+is reserved. Such "periodic" transfers are awkward to use through usbfs,
+unless you're using the asynchronous calls. However, interrupt transfers
+can also be used in a synchronous "one shot" style.
+
+Your user-mode driver should never need to worry about cleaning up
+request state when the device is disconnected, although it should close
+its open file descriptors as soon as it starts seeing the ENODEV errors.
+
+The ioctl() Requests
+--------------------
+
+To use these ioctls, you need to include the following headers in your
+userspace program:
+
+::
+
+    #include <linux/usb.h>
+    #include <linux/usbdevice_fs.h>
+    #include <asm/byteorder.h>
+
+The standard USB device model requests, from "Chapter 9" of the USB 2.0
+specification, are automatically included from the ``<linux/usb/ch9.h>``
+header.
+
+Unless noted otherwise, the ioctl requests described here will update
+the modification time on the usbfs file to which they are applied
+(unless they fail). A return of zero indicates success; otherwise, a
+standard USB error code is returned. (These are documented in
+``Documentation/usb/error-codes.txt`` in your kernel sources.)
+
+Each of these files multiplexes access to several I/O streams, one per
+endpoint. Each device has one control endpoint (endpoint zero) which
+supports a limited RPC style RPC access. Devices are configured by
+hub_wq (in the kernel) setting a device-wide *configuration* that
+affects things like power consumption and basic functionality. The
+endpoints are part of USB *interfaces*, which may have *altsettings*
+affecting things like which endpoints are available. Many devices only
+have a single configuration and interface, so drivers for them will
+ignore configurations and altsettings.
+
+Management/Status Requests
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A number of usbfs requests don't deal very directly with device I/O.
+They mostly relate to device management and status. These are all
+synchronous requests.
+
+USBDEVFS_CLAIMINTERFACE
+    This is used to force usbfs to claim a specific interface, which has
+    not previously been claimed by usbfs or any other kernel driver. The
+    ioctl parameter is an integer holding the number of the interface
+    (bInterfaceNumber from descriptor).
+
+    Note that if your driver doesn't claim an interface before trying to
+    use one of its endpoints, and no other driver has bound to it, then
+    the interface is automatically claimed by usbfs.
+
+    This claim will be released by a RELEASEINTERFACE ioctl, or by
+    closing the file descriptor. File modification time is not updated
+    by this request.
+
+USBDEVFS_CONNECTINFO
+    Says whether the device is lowspeed. The ioctl parameter points to a
+    structure like this:
+
+    ::
+
+        struct usbdevfs_connectinfo {
+                unsigned int   devnum;
+                unsigned char  slow;
+        };
+
+    File modification time is not updated by this request.
+
+    *You can't tell whether a "not slow" device is connected at high
+    speed (480 MBit/sec) or just full speed (12 MBit/sec).* You should
+    know the devnum value already, it's the DDD value of the device file
+    name.
+
+USBDEVFS_GETDRIVER
+    Returns the name of the kernel driver bound to a given interface (a
+    string). Parameter is a pointer to this structure, which is
+    modified:
+
+    ::
+
+        struct usbdevfs_getdriver {
+                unsigned int  interface;
+                char          driver[USBDEVFS_MAXDRIVERNAME + 1];
+        };
+
+    File modification time is not updated by this request.
+
+USBDEVFS_IOCTL
+    Passes a request from userspace through to a kernel driver that has
+    an ioctl entry in the *struct usb_driver* it registered.
+
+    ::
+
+        struct usbdevfs_ioctl {
+                int     ifno;
+                int     ioctl_code;
+                void    *data;
+        };
+
+        /* user mode call looks like this.
+         * 'request' becomes the driver->ioctl() 'code' parameter.
+         * the size of 'param' is encoded in 'request', and that data
+         * is copied to or from the driver->ioctl() 'buf' parameter.
+         */
+        static int
+        usbdev_ioctl (int fd, int ifno, unsigned request, void *param)
+        {
+                struct usbdevfs_ioctl   wrapper;
+
+                wrapper.ifno = ifno;
+                wrapper.ioctl_code = request;
+                wrapper.data = param;
+
+                return ioctl (fd, USBDEVFS_IOCTL, &wrapper);
+        }
+
+    File modification time is not updated by this request.
+
+    This request lets kernel drivers talk to user mode code through
+    filesystem operations even when they don't create a character or
+    block special device. It's also been used to do things like ask
+    devices what device special file should be used. Two pre-defined
+    ioctls are used to disconnect and reconnect kernel drivers, so that
+    user mode code can completely manage binding and configuration of
+    devices.
+
+USBDEVFS_RELEASEINTERFACE
+    This is used to release the claim usbfs made on interface, either
+    implicitly or because of a USBDEVFS_CLAIMINTERFACE call, before the
+    file descriptor is closed. The ioctl parameter is an integer holding
+    the number of the interface (bInterfaceNumber from descriptor); File
+    modification time is not updated by this request.
+
+        **Warning**
+
+        *No security check is made to ensure that the task which made
+        the claim is the one which is releasing it. This means that user
+        mode driver may interfere other ones.*
+
+USBDEVFS_RESETEP
+    Resets the data toggle value for an endpoint (bulk or interrupt) to
+    DATA0. The ioctl parameter is an integer endpoint number (1 to 15,
+    as identified in the endpoint descriptor), with USB_DIR_IN added
+    if the device's endpoint sends data to the host.
+
+        **Warning**
+
+        *Avoid using this request. It should probably be removed.* Using
+        it typically means the device and driver will lose toggle
+        synchronization. If you really lost synchronization, you likely
+        need to completely handshake with the device, using a request
+        like CLEAR_HALT or SET_INTERFACE.
+
+USBDEVFS_DROP_PRIVILEGES
+    This is used to relinquish the ability to do certain operations
+    which are considered to be privileged on a usbfs file descriptor.
+    This includes claiming arbitrary interfaces, resetting a device on
+    which there are currently claimed interfaces from other users, and
+    issuing USBDEVFS_IOCTL calls. The ioctl parameter is a 32 bit mask
+    of interfaces the user is allowed to claim on this file descriptor.
+    You may issue this ioctl more than one time to narrow said mask.
+
+Synchronous I/O Support
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Synchronous requests involve the kernel blocking until the user mode
+request completes, either by finishing successfully or by reporting an
+error. In most cases this is the simplest way to use usbfs, although as
+noted above it does prevent performing I/O to more than one endpoint at
+a time.
+
+USBDEVFS_BULK
+    Issues a bulk read or write request to the device. The ioctl
+    parameter is a pointer to this structure:
+
+    ::
+
+        struct usbdevfs_bulktransfer {
+                unsigned int  ep;
+                unsigned int  len;
+                unsigned int  timeout; /* in milliseconds */
+                void          *data;
+        };
+
+    The "ep" value identifies a bulk endpoint number (1 to 15, as
+    identified in an endpoint descriptor), masked with USB_DIR_IN when
+    referring to an endpoint which sends data to the host from the
+    device. The length of the data buffer is identified by "len"; Recent
+    kernels support requests up to about 128KBytes. *FIXME say how read
+    length is returned, and how short reads are handled.*.
+
+USBDEVFS_CLEAR_HALT
+    Clears endpoint halt (stall) and resets the endpoint toggle. This is
+    only meaningful for bulk or interrupt endpoints. The ioctl parameter
+    is an integer endpoint number (1 to 15, as identified in an endpoint
+    descriptor), masked with USB_DIR_IN when referring to an endpoint
+    which sends data to the host from the device.
+
+    Use this on bulk or interrupt endpoints which have stalled,
+    returning *-EPIPE* status to a data transfer request. Do not issue
+    the control request directly, since that could invalidate the host's
+    record of the data toggle.
+
+USBDEVFS_CONTROL
+    Issues a control request to the device. The ioctl parameter points
+    to a structure like this:
+
+    ::
+
+        struct usbdevfs_ctrltransfer {
+                __u8   bRequestType;
+                __u8   bRequest;
+                __u16  wValue;
+                __u16  wIndex;
+                __u16  wLength;
+                __u32  timeout;  /* in milliseconds */
+                void   *data;
+        };
+
+    The first eight bytes of this structure are the contents of the
+    SETUP packet to be sent to the device; see the USB 2.0 specification
+    for details. The bRequestType value is composed by combining a
+    USB_TYPE_\* value, a USB_DIR_\* value, and a USB_RECIP_\*
+    value (from *<linux/usb.h>*). If wLength is nonzero, it describes
+    the length of the data buffer, which is either written to the device
+    (USB_DIR_OUT) or read from the device (USB_DIR_IN).
+
+    At this writing, you can't transfer more than 4 KBytes of data to or
+    from a device; usbfs has a limit, and some host controller drivers
+    have a limit. (That's not usually a problem.) *Also* there's no way
+    to say it's not OK to get a short read back from the device.
+
+USBDEVFS_RESET
+    Does a USB level device reset. The ioctl parameter is ignored. After
+    the reset, this rebinds all device interfaces. File modification
+    time is not updated by this request.
+
+        **Warning**
+
+        *Avoid using this call* until some usbcore bugs get fixed, since
+        it does not fully synchronize device, interface, and driver (not
+        just usbfs) state.
+
+USBDEVFS_SETINTERFACE
+    Sets the alternate setting for an interface. The ioctl parameter is
+    a pointer to a structure like this:
+
+    ::
+
+        struct usbdevfs_setinterface {
+                unsigned int  interface;
+                unsigned int  altsetting;
+        };
+
+    File modification time is not updated by this request.
+
+    Those struct members are from some interface descriptor applying to
+    the current configuration. The interface number is the
+    bInterfaceNumber value, and the altsetting number is the
+    bAlternateSetting value. (This resets each endpoint in the
+    interface.)
+
+USBDEVFS_SETCONFIGURATION
+    Issues the :c:func:`usb_set_configuration()` call for the
+    device. The parameter is an integer holding the number of a
+    configuration (bConfigurationValue from descriptor). File
+    modification time is not updated by this request.
+
+        **Warning**
+
+        *Avoid using this call* until some usbcore bugs get fixed, since
+        it does not fully synchronize device, interface, and driver (not
+        just usbfs) state.
+
+Asynchronous I/O Support
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+As mentioned above, there are situations where it may be important to
+initiate concurrent operations from user mode code. This is particularly
+important for periodic transfers (interrupt and isochronous), but it can
+be used for other kinds of USB requests too. In such cases, the
+asynchronous requests described here are essential. Rather than
+submitting one request and having the kernel block until it completes,
+the blocking is separate.
+
+These requests are packaged into a structure that resembles the URB used
+by kernel device drivers. (No POSIX Async I/O support here, sorry.) It
+identifies the endpoint type (USBDEVFS_URB_TYPE_\*), endpoint
+(number, masked with USB_DIR_IN as appropriate), buffer and length,
+and a user "context" value serving to uniquely identify each request.
+(It's usually a pointer to per-request data.) Flags can modify requests
+(not as many as supported for kernel drivers).
+
+Each request can specify a realtime signal number (between SIGRTMIN and
+SIGRTMAX, inclusive) to request a signal be sent when the request
+completes.
+
+When usbfs returns these urbs, the status value is updated, and the
+buffer may have been modified. Except for isochronous transfers, the
+actual_length is updated to say how many bytes were transferred; if the
+USBDEVFS_URB_DISABLE_SPD flag is set ("short packets are not OK"), if
+fewer bytes were read than were requested then you get an error report.
+
+::
+
+    struct usbdevfs_iso_packet_desc {
+            unsigned int                     length;
+            unsigned int                     actual_length;

+            int                              buffer_length;
+            int                              actual_length;
+            int                              start_frame;
+            int                              number_of_packets;
+            int                              error_count;
+            unsigned int                     signr;

+            struct usbdevfs_iso_packet_desc  iso_frame_desc[];
+    };
+
+For these asynchronous requests, the file modification time reflects
+when the request was initiated. This contrasts with their use with the
+synchronous requests, where it reflects when requests complete.

-Introduction
-============
-
-This document describes how to use the dynamic debug (dyndbg) feature.
-
-Dynamic debug is designed to allow you to dynamically enable/disable
-kernel code to obtain additional kernel information.  Currently, if
-CONFIG_DYNAMIC_DEBUG is set, then all pr_debug()/dev_dbg() and
-print_hex_dump_debug()/print_hex_dump_bytes() calls can be dynamically
-enabled per-callsite.
-
-If CONFIG_DYNAMIC_DEBUG is not set, print_hex_dump_debug() is just
-shortcut for print_hex_dump(KERN_DEBUG).
-
-For print_hex_dump_debug()/print_hex_dump_bytes(), format string is
-its 'prefix_str' argument, if it is constant string; or "hexdump"
-in case 'prefix_str' is build dynamically.
-
-Dynamic debug has even more useful features:
-
- * Simple query language allows turning on and off debugging
-   statements by matching any combination of 0 or 1 of:
-
-   - source filename
-   - function name
-   - line number (including ranges of line numbers)
-   - module name
-   - format string
-
- * Provides a debugfs control file: <debugfs>/dynamic_debug/control
-   which can be read to display the complete list of known debug
-   statements, to help guide you
-
-Controlling dynamic debug Behaviour
-===================================
-
-The behaviour of pr_debug()/dev_dbg()s are controlled via writing to a
-control file in the 'debugfs' filesystem. Thus, you must first mount
-the debugfs filesystem, in order to make use of this feature.
-Subsequently, we refer to the control file as:
-<debugfs>/dynamic_debug/control. For example, if you want to enable
-printing from source file 'svcsock.c', line 1603 you simply do:
-
-nullarbor:~ # echo 'file svcsock.c line 1603 +p' >
-				<debugfs>/dynamic_debug/control
-
-If you make a mistake with the syntax, the write will fail thus:
-
-nullarbor:~ # echo 'file svcsock.c wtf 1 +p' >
-				<debugfs>/dynamic_debug/control
--bash: echo: write error: Invalid argument
-
-Viewing Dynamic Debug Behaviour
-===========================
-
-You can view the currently configured behaviour of all the debug
-statements via:
-
-nullarbor:~ # cat <debugfs>/dynamic_debug/control
-# filename:lineno [module]function flags format
-/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:323 [svcxprt_rdma]svc_rdma_cleanup =_ "SVCRDMA Module Removed, deregister RPC RDMA transport\012"
-/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:341 [svcxprt_rdma]svc_rdma_init =_ "\011max_inline       : %d\012"
-/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:340 [svcxprt_rdma]svc_rdma_init =_ "\011sq_depth         : %d\012"
-/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:338 [svcxprt_rdma]svc_rdma_init =_ "\011max_requests     : %d\012"
-...
-
-
-You can also apply standard Unix text manipulation filters to this
-data, e.g.
-
-nullarbor:~ # grep -i rdma <debugfs>/dynamic_debug/control  | wc -l
-62
-
-nullarbor:~ # grep -i tcp <debugfs>/dynamic_debug/control | wc -l
-42
-
-The third column shows the currently enabled flags for each debug
-statement callsite (see below for definitions of the flags).  The
-default value, with no flags enabled, is "=_".  So you can view all
-the debug statement callsites with any non-default flags:
-
-nullarbor:~ # awk '$3 != "=_"' <debugfs>/dynamic_debug/control
-# filename:lineno [module]function flags format
-/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svcsock.c:1603 [sunrpc]svc_send p "svc_process: st_sendto returned %d\012"
-
-
-Command Language Reference
-==========================
-
-At the lexical level, a command comprises a sequence of words separated
-by spaces or tabs.  So these are all equivalent:
-
-nullarbor:~ # echo -c 'file svcsock.c line 1603 +p' >
-				<debugfs>/dynamic_debug/control
-nullarbor:~ # echo -c '  file   svcsock.c     line  1603 +p  ' >
-				<debugfs>/dynamic_debug/control
-nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
-				<debugfs>/dynamic_debug/control
-
-Command submissions are bounded by a write() system call.
-Multiple commands can be written together, separated by ';' or '\n'.
-
-  ~# echo "func pnpacpi_get_resources +p; func pnp_assign_mem +p" \
-     > <debugfs>/dynamic_debug/control
-
-If your query set is big, you can batch them too:
-
-  ~# cat query-batch-file > <debugfs>/dynamic_debug/control
-
-A another way is to use wildcard. The match rule support '*' (matches
-zero or more characters) and '?' (matches exactly one character).For
-example, you can match all usb drivers:
-
-  ~# echo "file drivers/usb/* +p" > <debugfs>/dynamic_debug/control
-
-At the syntactical level, a command comprises a sequence of match
-specifications, followed by a flags change specification.
-
-command ::= match-spec* flags-spec
-
-The match-spec's are used to choose a subset of the known pr_debug()
-callsites to which to apply the flags-spec.  Think of them as a query
-with implicit ANDs between each pair.  Note that an empty list of
-match-specs will select all debug statement callsites.
-
-A match specification comprises a keyword, which controls the
-attribute of the callsite to be compared, and a value to compare
-against.  Possible keywords are:
-
-match-spec ::= 'func' string |
-	       'file' string |
-	       'module' string |
-	       'format' string |
-	       'line' line-range
-
-line-range ::= lineno |
-	       '-'lineno |
-	       lineno'-' |
-	       lineno'-'lineno
-// Note: line-range cannot contain space, e.g.
-// "1-30" is valid range but "1 - 30" is not.
-
-lineno ::= unsigned-int
-
-The meanings of each keyword are:
-
-func
-    The given string is compared against the function name
-    of each callsite.  Example:
-
-    func svc_tcp_accept
-
-file
-    The given string is compared against either the full pathname, the
-    src-root relative pathname, or the basename of the source file of
-    each callsite.  Examples:
-
-    file svcsock.c
-    file kernel/freezer.c
-    file /usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svcsock.c
-
-module
-    The given string is compared against the module name
-    of each callsite.  The module name is the string as
-    seen in "lsmod", i.e. without the directory or the .ko
-    suffix and with '-' changed to '_'.  Examples:
-
-    module sunrpc
-    module nfsd
-
-format
-    The given string is searched for in the dynamic debug format
-    string.  Note that the string does not need to match the
-    entire format, only some part.  Whitespace and other
-    special characters can be escaped using C octal character
-    escape \ooo notation, e.g. the space character is \040.
-    Alternatively, the string can be enclosed in double quote
-    characters (") or single quote characters (').
-    Examples:
-
-    format svcrdma:	    // many of the NFS/RDMA server pr_debugs
-    format readahead	    // some pr_debugs in the readahead cache
-    format nfsd:\040SETATTR // one way to match a format with whitespace
-    format "nfsd: SETATTR"  // a neater way to match a format with whitespace
-    format 'nfsd: SETATTR'  // yet another way to match a format with whitespace
-
-line
-    The given line number or range of line numbers is compared
-    against the line number of each pr_debug() callsite.  A single
-    line number matches the callsite line number exactly.  A
-    range of line numbers matches any callsite between the first
-    and last line number inclusive.  An empty first number means
-    the first line in the file, an empty line number means the
-    last number in the file.  Examples:
-
-    line 1603	    // exactly line 1603
-    line 1600-1605  // the six lines from line 1600 to line 1605
-    line -1605	    // the 1605 lines from line 1 to line 1605
-    line 1600-	    // all lines from line 1600 to the end of the file
-
-The flags specification comprises a change operation followed
-by one or more flag characters.  The change operation is one
-of the characters:
-
-  -    remove the given flags
-  +    add the given flags
-  =    set the flags to the given flags
-
-The flags are:
-
-  p    enables the pr_debug() callsite.
-  f    Include the function name in the printed message
-  l    Include line number in the printed message
-  m    Include module name in the printed message
-  t    Include thread ID in messages not generated from interrupt context
-  _    No flags are set. (Or'd with others on input)
-
-For print_hex_dump_debug() and print_hex_dump_bytes(), only 'p' flag
-have meaning, other flags ignored.
-
-For display, the flags are preceded by '='
-(mnemonic: what the flags are currently equal to).
-
-Note the regexp ^[-+=][flmpt_]+$ matches a flags specification.
-To clear all flags at once, use "=_" or "-flmpt".
-
-
-Debug messages during Boot Process
-==================================
-
-To activate debug messages for core code and built-in modules during
-the boot process, even before userspace and debugfs exists, use
-dyndbg="QUERY", module.dyndbg="QUERY", or ddebug_query="QUERY"
-(ddebug_query is obsoleted by dyndbg, and deprecated).  QUERY follows
-the syntax described above, but must not exceed 1023 characters.  Your
-bootloader may impose lower limits.
-
-These dyndbg params are processed just after the ddebug tables are
-processed, as part of the arch_initcall.  Thus you can enable debug
-messages in all code run after this arch_initcall via this boot
-parameter.
-
-On an x86 system for example ACPI enablement is a subsys_initcall and
-   dyndbg="file ec.c +p"
-will show early Embedded Controller transactions during ACPI setup if
-your machine (typically a laptop) has an Embedded Controller.
-PCI (or other devices) initialization also is a hot candidate for using
-this boot parameter for debugging purposes.
-
-If foo module is not built-in, foo.dyndbg will still be processed at
-boot time, without effect, but will be reprocessed when module is
-loaded later.  dyndbg_query= and bare dyndbg= are only processed at
-boot.
-
-
-Debug Messages at Module Initialization Time
-============================================
-
-When "modprobe foo" is called, modprobe scans /proc/cmdline for
-foo.params, strips "foo.", and passes them to the kernel along with
-params given in modprobe args or /etc/modprob.d/*.conf files,
-in the following order:
-
-1. # parameters given via /etc/modprobe.d/*.conf
-   options foo dyndbg=+pt
-   options foo dyndbg # defaults to +p
-
-2. # foo.dyndbg as given in boot args, "foo." is stripped and passed
-   foo.dyndbg=" func bar +p; func buz +mp"
-
-3. # args to modprobe
-   modprobe foo dyndbg==pmf # override previous settings
-
-These dyndbg queries are applied in order, with last having final say.
-This allows boot args to override or modify those from /etc/modprobe.d
-(sensible, since 1 is system wide, 2 is kernel or boot specific), and
-modprobe args to override both.
-
-In the foo.dyndbg="QUERY" form, the query must exclude "module foo".
-"foo" is extracted from the param-name, and applied to each query in
-"QUERY", and only 1 match-spec of each type is allowed.
-
-The dyndbg option is a "fake" module parameter, which means:
-
-- modules do not need to define it explicitly
-- every module gets it tacitly, whether they use pr_debug or not
-- it doesn't appear in /sys/module/$module/parameters/
-  To see it, grep the control file, or inspect /proc/cmdline.
-
-For CONFIG_DYNAMIC_DEBUG kernels, any settings given at boot-time (or
-enabled by -DDEBUG flag during compilation) can be disabled later via
-the sysfs interface if the debug messages are no longer needed:
-
-   echo "module module_name -p" > <debugfs>/dynamic_debug/control
-
-Examples
-========
-
-// enable the message at line 1603 of file svcsock.c
-nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
-				<debugfs>/dynamic_debug/control
-
-// enable all the messages in file svcsock.c

-EDAC - Error Detection And Correction
-=====================================
-
-"bluesmoke" was the name for this device driver when it
-was "out-of-tree" and maintained at sourceforge.net -
-bluesmoke.sourceforge.net. That site is mostly archaic now and can be
-used only for historical purposes.
-
-When the subsystem was pushed into 2.6.16 for the first time, it was
-renamed to 'EDAC'.
-
-PURPOSE
--------
-
-The 'edac' kernel module's goal is to detect and report hardware errors
-that occur within the computer system running under linux.
-
-MEMORY
-------
-
-Memory Correctable Errors (CE) and Uncorrectable Errors (UE) are the
-primary errors being harvested. These types of errors are harvested by
-the 'edac_mc' device.
-
-Detecting CE events, then harvesting those events and reporting them,
-*can* but must not necessarily be a predictor of future UE events. With
-CE events only, the system can and will continue to operate as no data
-has been damaged yet.
-
-However, preventive maintenance and proactive part replacement of memory
-DIMMs exhibiting CEs can reduce the likelihood of the dreaded UE events
-and system panics.
-
-OTHER HARDWARE ELEMENTS
------------------------
-
-A new feature for EDAC, the edac_device class of device, was added in
-the 2.6.23 version of the kernel.
-
-This new device type allows for non-memory type of ECC hardware detectors
-to have their states harvested and presented to userspace via the sysfs
-interface.
-
-Some architectures have ECC detectors for L1, L2 and L3 caches,
-along with DMA engines, fabric switches, main data path switches,
-interconnections, and various other hardware data paths. If the hardware
-reports it, then a edac_device device probably can be constructed to
-harvest and present that to userspace.
-
-
-PCI BUS SCANNING
-----------------
-
-In addition, PCI devices are scanned for PCI Bus Parity and SERR Errors
-in order to determine if errors are occurring during data transfers.
-
-The presence of PCI Parity errors must be examined with a grain of salt.
-There are several add-in adapters that do *not* follow the PCI specification
-with regards to Parity generation and reporting. The specification says
-the vendor should tie the parity status bits to 0 if they do not intend
-to generate parity.  Some vendors do not do this, and thus the parity bit
-can "float" giving false positives.
-
-There is a PCI device attribute located in sysfs that is checked by
-the EDAC PCI scanning code. If that attribute is set, PCI parity/error
-scanning is skipped for that device. The attribute is:
-
-	broken_parity_status
-
-and is located in /sys/devices/pci<XXX>/0000:XX:YY.Z directories for
-PCI devices.
-
-
-VERSIONING
-----------
-
-EDAC is composed of a "core" module (edac_core.ko) and several Memory
-Controller (MC) driver modules. On a given system, the CORE is loaded
-and one MC driver will be loaded. Both the CORE and the MC driver (or
-edac_device driver) have individual versions that reflect current
-release level of their respective modules.
-
-Thus, to "report" on what version a system is running, one must report
-both the CORE's and the MC driver's versions.
-
-
-LOADING
--------
-
-If 'edac' was statically linked with the kernel then no loading
-is necessary. If 'edac' was built as modules then simply modprobe
-the 'edac' pieces that you need. You should be able to modprobe
-hardware-specific modules and have the dependencies load the necessary
-core modules.
-
-Example:
-
-$> modprobe amd76x_edac
-
-loads both the amd76x_edac.ko memory controller module and the edac_mc.ko
-core module.
-
-
-SYSFS INTERFACE
----------------
-
-EDAC presents a 'sysfs' interface for control and reporting purposes. It
-lives in the /sys/devices/system/edac directory.
-
-Within this directory there currently reside 2 components:
-
-	mc	memory controller(s) system
-	pci	PCI control and status system
-
-
-
-Memory Controller (mc) Model
-----------------------------
-
-Each 'mc' device controls a set of DIMM memory modules. These modules
-are laid out in a Chip-Select Row (csrowX) and Channel table (chX).
-There can be multiple csrows and multiple channels.
-
-Memory controllers allow for several csrows, with 8 csrows being a
-typical value. Yet, the actual number of csrows depends on the layout of
-a given motherboard, memory controller and DIMM characteristics.
-
-Dual channels allows for 128 bit data transfers to/from the CPU from/to
-memory. Some newer chipsets allow for more than 2 channels, like Fully
-Buffered DIMMs (FB-DIMMs). The following example will assume 2 channels:
-
-
-		Channel 0	Channel 1
-	===================================
-	csrow0	| DIMM_A0	| DIMM_B0 |
-	csrow1	| DIMM_A0	| DIMM_B0 |
-	===================================
-
-	===================================
-	csrow2	| DIMM_A1	| DIMM_B1 |
-	csrow3	| DIMM_A1	| DIMM_B1 |
-	===================================
-
-In the above example table there are 4 physical slots on the motherboard
-for memory DIMMs:
-
-	DIMM_A0
-	DIMM_B0
-	DIMM_A1
-	DIMM_B1
-
-Labels for these slots are usually silk-screened on the motherboard.
-Slots labeled 'A' are channel 0 in this example. Slots labeled 'B' are
-channel 1. Notice that there are two csrows possible on a physical DIMM.
-These csrows are allocated their csrow assignment based on the slot into
-which the memory DIMM is placed. Thus, when 1 DIMM is placed in each
-Channel, the csrows cross both DIMMs.
-
-Memory DIMMs come single or dual "ranked". A rank is a populated csrow.
-Thus, 2 single ranked DIMMs, placed in slots DIMM_A0 and DIMM_B0 above
-will have 1 csrow, csrow0. csrow1 will be empty. On the other hand,
-when 2 dual ranked DIMMs are similarly placed, then both csrow0 and
-csrow1 will be populated. The pattern repeats itself for csrow2 and
-csrow3.
-
-The representation of the above is reflected in the directory
-tree in EDAC's sysfs interface. Starting in directory
-/sys/devices/system/edac/mc each memory controller will be represented
-by its own 'mcX' directory, where 'X' is the index of the MC.
-
-
-	..../edac/mc/
-		   |
-		   |->mc0
-		   |->mc1
-		   |->mc2
-		   ....
-
-Under each 'mcX' directory each 'csrowX' is again represented by a
-'csrowX', where 'X' is the csrow index:
-
-
-	.../mc/mc0/
-		|
-		|->csrow0
-		|->csrow2
-		|->csrow3
-		....
-
-Notice that there is no csrow1, which indicates that csrow0 is composed
-of a single ranked DIMMs. This should also apply in both Channels, in
-order to have dual-channel mode be operational. Since both csrow2 and
-csrow3 are populated, this indicates a dual ranked set of DIMMs for
-channels 0 and 1.
-
-
-Within each of the 'mcX' and 'csrowX' directories are several EDAC
-control and attribute files.
-
-
-'mcX' directories
------------------
-
-In 'mcX' directories are EDAC control and attribute files for
-this 'X' instance of the memory controllers.
-
-For a description of the sysfs API, please see:
-	Documentation/ABI/testing/sysfs-devices-edac
-
-
-
-'csrowX' directories
---------------------
-
-When CONFIG_EDAC_LEGACY_SYSFS is enabled, sysfs will contain the csrowX
-directories. As this API doesn't work properly for Rambus, FB-DIMMs and
-modern Intel Memory Controllers, this is being deprecated in favor of
-dimmX directories.
-
-In the 'csrowX' directories are EDAC control and attribute files for
-this 'X' instance of csrow:
-
-
-Total Uncorrectable Errors count attribute file:
-
-	'ue_count'
-
-	This attribute file displays the total count of uncorrectable
-	errors that have occurred on this csrow. If panic_on_ue is set
-	this counter will not have a chance to increment, since EDAC
-	will panic the system.
-
-
-Total Correctable Errors count attribute file:
-
-	'ce_count'
-
-	This attribute file displays the total count of correctable
-	errors that have occurred on this csrow. This count is very
-	important to examine. CEs provide early indications that a
-	DIMM is beginning to fail. This count field should be
-	monitored for non-zero values and report such information
-	to the system administrator.
-
-
-Total memory managed by this csrow attribute file:
-
-	'size_mb'
-
-	This attribute file displays, in count of megabytes, the memory
-	that this csrow contains.
-
-
-Memory Type attribute file:
-
-	'mem_type'
-
-	This attribute file will display what type of memory is currently
-	on this csrow. Normally, either buffered or unbuffered memory.
-	Examples:
-		Registered-DDR
-		Unbuffered-DDR
-
-
-EDAC Mode of operation attribute file:
-
-	'edac_mode'
-
-	This attribute file will display what type of Error detection
-	and correction is being utilized.
-
-
-Device type attribute file:
-
-	'dev_type'
-
-	This attribute file will display what type of DRAM device is
-	being utilized on this DIMM.
-	Examples:
-		x1
-		x2
-		x4
-		x8
-
-
-Channel 0 CE Count attribute file:
-
-	'ch0_ce_count'
-
-	This attribute file will display the count of CEs on this
-	DIMM located in channel 0.
-
-
-Channel 0 UE Count attribute file:
-
-	'ch0_ue_count'
-
-	This attribute file will display the count of UEs on this
-	DIMM located in channel 0.
-
-
-Channel 0 DIMM Label control file:
-
-	'ch0_dimm_label'
-
-	This control file allows this DIMM to have a label assigned
-	to it. With this label in the module, when errors occur
-	the output can provide the DIMM label in the system log.
-	This becomes vital for panic events to isolate the
-	cause of the UE event.
-
-	DIMM Labels must be assigned after booting, with information
-	that correctly identifies the physical slot with its
-	silk screen label. This information is currently very
-	motherboard specific and determination of this information
-	must occur in userland at this time.
-
-
-Channel 1 CE Count attribute file:
-
-	'ch1_ce_count'
-
-	This attribute file will display the count of CEs on this
-	DIMM located in channel 1.
-
-
-Channel 1 UE Count attribute file:
-
-	'ch1_ue_count'
-
-	This attribute file will display the count of UEs on this
-	DIMM located in channel 0.
-
-
-Channel 1 DIMM Label control file:
-
-	'ch1_dimm_label'
-
-	This control file allows this DIMM to have a label assigned
-	to it. With this label in the module, when errors occur
-	the output can provide the DIMM label in the system log.
-	This becomes vital for panic events to isolate the
-	cause of the UE event.
-
-	DIMM Labels must be assigned after booting, with information
-	that correctly identifies the physical slot with its
-	silk screen label. This information is currently very
-	motherboard specific and determination of this information
-	must occur in userland at this time.
-
-
-
-SYSTEM LOGGING
---------------
-
-If logging for UEs and CEs is enabled, then system logs will contain
-information indicating that errors have been detected:
-
-EDAC MC0: CE page 0x283, offset 0xce0, grain 8, syndrome 0x6ec3, row 0,
-channel 1 "DIMM_B1": amd76x_edac
-
-EDAC MC0: CE page 0x1e5, offset 0xfb0, grain 8, syndrome 0xb741, row 0,
-channel 1 "DIMM_B1": amd76x_edac
-
-
-The structure of the message is:
-	the memory controller			(MC0)
-	Error type				(CE)
-	memory page				(0x283)
-	offset in the page			(0xce0)
-	the byte granularity 			(grain 8)
-		or resolution of the error
-	the error syndrome			(0xb741)
-	memory row				(row 0)
-	memory channel				(channel 1)
-	DIMM label, if set prior		(DIMM B1
-	and then an optional, driver-specific message that may
-		have additional information.
-
-Both UEs and CEs with no info will lack all but memory controller, error
-type, a notice of "no info" and then an optional, driver-specific error
-message.
-
-
-PCI Bus Parity Detection
-------------------------
-
-On Header Type 00 devices, the primary status is looked at for any
-parity error regardless of whether parity is enabled on the device or
-not. (The spec indicates parity is generated in some cases). On Header
-Type 01 bridges, the secondary status register is also looked at to see
-if parity occurred on the bus on the other side of the bridge.
-
-
-SYSFS CONFIGURATION
--------------------
-
-Under /sys/devices/system/edac/pci are control and attribute files as follows:
-
-
-Enable/Disable PCI Parity checking control file:
-
-	'check_pci_parity'
-
-
-	This control file enables or disables the PCI Bus Parity scanning
-	operation. Writing a 1 to this file enables the scanning. Writing
-	a 0 to this file disables the scanning.
-
-	Enable:
-	echo "1" >/sys/devices/system/edac/pci/check_pci_parity
-
-	Disable:
-	echo "0" >/sys/devices/system/edac/pci/check_pci_parity
-
-
-Parity Count:
-
-	'pci_parity_count'
-
-	This attribute file will display the number of parity errors that
-	have been detected.
-
-
-
-MODULE PARAMETERS
------------------
-
-Panic on UE control file:
-
-	'edac_mc_panic_on_ue'
-
-	An uncorrectable error will cause a machine panic.  This is usually
-	desirable.  It is a bad idea to continue when an uncorrectable error
-	occurs - it is indeterminate what was uncorrected and the operating
-	system context might be so mangled that continuing will lead to further
-	corruption. If the kernel has MCE configured, then EDAC will never
-	notice the UE.
-
-	LOAD TIME: module/kernel parameter: edac_mc_panic_on_ue=[0|1]
-
-	RUN TIME:  echo "1" > /sys/module/edac_core/parameters/edac_mc_panic_on_ue
-
-
-Log UE control file:
-
-	'edac_mc_log_ue'
-
-	Generate kernel messages describing uncorrectable errors.  These errors
-	are reported through the system message log system.  UE statistics
-	will be accumulated even when UE logging is disabled.
-
-	LOAD TIME: module/kernel parameter: edac_mc_log_ue=[0|1]
-
-	RUN TIME: echo "1" > /sys/module/edac_core/parameters/edac_mc_log_ue
-
-
-Log CE control file:
-
-	'edac_mc_log_ce'
-
-	Generate kernel messages describing correctable errors.  These
-	errors are reported through the system message log system.
-	CE statistics will be accumulated even when CE logging is disabled.
-
-	LOAD TIME: module/kernel parameter: edac_mc_log_ce=[0|1]
-
-	RUN TIME: echo "1" > /sys/module/edac_core/parameters/edac_mc_log_ce
-
-
-Polling period control file:
-
-	'edac_mc_poll_msec'
-
-	The time period, in milliseconds, for polling for error information.
-	Too small a value wastes resources.  Too large a value might delay
-	necessary handling of errors and might loose valuable information for
-	locating the error.  1000 milliseconds (once each second) is the current
-	default. Systems which require all the bandwidth they can get, may
-	increase this.
-
-	LOAD TIME: module/kernel parameter: edac_mc_poll_msec=[0|1]
-
-	RUN TIME: echo "1000" > /sys/module/edac_core/parameters/edac_mc_poll_msec
-
-
-Panic on PCI PARITY Error:
-
-	'panic_on_pci_parity'
-
-
-	This control file enables or disables panicking when a parity
-	error has been detected.
-
-
-	module/kernel parameter: edac_panic_on_pci_pe=[0|1]
-
-	Enable:
-	echo "1" > /sys/module/edac_core/parameters/edac_panic_on_pci_pe
-
-	Disable:
-	echo "0" > /sys/module/edac_core/parameters/edac_panic_on_pci_pe
-
-
-
-EDAC device type
-----------------
-
-In the header file, edac_core.h, there is a series of edac_device structures
-and APIs for the EDAC_DEVICE.
-
-User space access to an edac_device is through the sysfs interface.
-
-At the location /sys/devices/system/edac (sysfs) new edac_device devices will
-appear.
-
-There is a three level tree beneath the above 'edac' directory. For example,
-the 'test_device_edac' device (found at the bluesmoke.sourceforget.net website)
-installs itself as:
-
-	/sys/devices/systm/edac/test-instance
-
-in this directory are various controls, a symlink and one or more 'instance'
-directories.
-
-The standard default controls are:
-
-	log_ce		boolean to log CE events
-	log_ue		boolean to log UE events
-	panic_on_ue	boolean to 'panic' the system if an UE is encountered
-			(default off, can be set true via startup script)
-	poll_msec	time period between POLL cycles for events
-
-The test_device_edac device adds at least one of its own custom control:
-
-	test_bits	which in the current test driver does nothing but
-			show how it is installed. A ported driver can
-			add one or more such controls and/or attributes
-			for specific uses.
-			One out-of-tree driver uses controls here to allow
-			for ERROR INJECTION operations to hardware
-			injection registers
-
-The symlink points to the 'struct dev' that is registered for this edac_device.
-
-INSTANCES
----------
-
-One or more instance directories are present. For the 'test_device_edac' case:
-
-	test-instance0
-
-
-In this directory there are two default counter attributes, which are totals of
-counter in deeper subdirectories.
-
-	ce_count	total of CE events of subdirectories
-	ue_count	total of UE events of subdirectories
-
-BLOCKS
-------
-
-At the lowest directory level is the 'block' directory. There can be 0, 1
-or more blocks specified in each instance.
-
-	test-block0
-
-
-In this directory the default attributes are:
-
-	ce_count	which is counter of CE events for this 'block'
-			of hardware being monitored
-	ue_count	which is counter of UE events for this 'block'
-			of hardware being monitored
-
-
-The 'test_device_edac' device adds 4 attributes and 1 control:
-
-	test-block-bits-0	for every POLL cycle this counter
-				is incremented
-	test-block-bits-1	every 10 cycles, this counter is bumped once,
-				and test-block-bits-0 is set to 0
-	test-block-bits-2	every 100 cycles, this counter is bumped once,
-				and test-block-bits-1 is set to 0
-	test-block-bits-3	every 1000 cycles, this counter is bumped once,
-				and test-block-bits-2 is set to 0
-
-
-	reset-counters		writing ANY thing to this control will
-				reset all the above counters.
-
-
-Use of the 'test_device_edac' driver should enable any others to create their own
-unique drivers for their hardware systems.
-
-The 'test_device_edac' sample driver is located at the
-bluesmoke.sourceforge.net project site for EDAC.
-
-
-NEHALEM USAGE OF EDAC APIs
---------------------------
-
-This chapter documents some EXPERIMENTAL mappings for EDAC API to handle
-Nehalem EDAC driver. They will likely be changed on future versions
-of the driver.
-
-Due to the way Nehalem exports Memory Controller data, some adjustments
-were done at i7core_edac driver. This chapter will cover those differences
-
-1) On Nehalem, there is one Memory Controller per Quick Patch Interconnect
-   (QPI). At the driver, the term "socket" means one QPI. This is
-   associated with a physical CPU socket.
-
-   Each MC have 3 physical read channels, 3 physical write channels and
-   3 logic channels. The driver currently sees it as just 3 channels.
-   Each channel can have up to 3 DIMMs.
-
-   The minimum known unity is DIMMs. There are no information about csrows.
-   As EDAC API maps the minimum unity is csrows, the driver sequentially
-   maps channel/dimm into different csrows.
-
-   For example, supposing the following layout:
-	Ch0 phy rd0, wr0 (0x063f4031): 2 ranks, UDIMMs
-	  dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
-	  dimm 1 1024 Mb offset: 4, bank: 8, rank: 1, row: 0x4000, col: 0x400
-        Ch1 phy rd1, wr1 (0x063f4031): 2 ranks, UDIMMs
-	  dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
-	Ch2 phy rd3, wr3 (0x063f4031): 2 ranks, UDIMMs
-	  dimm 0 1024 Mb offset: 0, bank: 8, rank: 1, row: 0x4000, col: 0x400
-   The driver will map it as:
-	csrow0: channel 0, dimm0
-	csrow1: channel 0, dimm1
-	csrow2: channel 1, dimm0
-	csrow3: channel 2, dimm0
-
-exports one
-   DIMM per csrow.
-
-   Each QPI is exported as a different memory controller.
-
-2) Nehalem MC has the ability to generate errors. The driver implements this
-   functionality via some error injection nodes:
-
-   For injecting a memory error, there are some sysfs nodes, under
-   /sys/devices/system/edac/mc/mc?/:
-
-   inject_addrmatch/*:
-      Controls the error injection mask register. It is possible to specify
-      several characteristics of the address to match an error code:
-         dimm = the affected dimm. Numbers are relative to a channel;
-         rank = the memory rank;
-         channel = the channel that will generate an error;
-         bank = the affected bank;
-         page = the page address;
-         column (or col) = the address column.
-      each of the above values can be set to "any" to match any valid value.
-
-      At driver init, all values are set to any.
-
-      For example, to generate an error at rank 1 of dimm 2, for any channel,
-      any bank, any page, any column:
-		echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
-		echo 1 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
-
-	To return to the default behaviour of matching any, you can do:
-		echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/dimm
-		echo any >/sys/devices/system/edac/mc/mc0/inject_addrmatch/rank
-
-   inject_eccmask:
-       specifies what bits will have troubles,
-
-   inject_section:
-       specifies what ECC cache section will get the error:
-		3 for both
-		2 for the highest
-		1 for the lowest
-
-   inject_type:
-       specifies the type of error, being a combination of the following bits:
-		bit 0 - repeat
-		bit 1 - ecc
-		bit 2 - parity
-
-       inject_enable starts the error generation when something different
-       than 0 is written.
-
-   All inject vars can be read. root permission is needed for write.
-
-   Datasheet states that the error will only be generated after a write on an
-   address that matches inject_addrmatch. It seems, however, that reading will
-   also produce an error.
-
-   For example, the following code will generate an error for any write access
-   at socket 0, on any DIMM/address on channel 2:
-
-   echo 2 >/sys/devices/system/edac/mc/mc0/inject_addrmatch/channel
-   echo 2 >/sys/devices/system/edac/mc/mc0/inject_type
-   echo 64 >/sys/devices/system/edac/mc/mc0/inject_eccmask
-   echo 3 >/sys/devices/system/edac/mc/mc0/inject_section
-   echo 1 >/sys/devices/system/edac/mc/mc0/inject_enable
-   dd if=/dev/mem of=/dev/null seek=16k bs=4k count=1 >& /dev/null
-
-   For socket 1, it is needed to replace "mc0" by "mc1" at the above
-   commands.
-
-   The generated error message will look like:
-
-   EDAC MC0: UE row 0, channel-a= 0 channel-b= 0 labels "-": NON_FATAL (addr = 0x0075b980, socket=0, Dimm=0, Channel=2, syndrome=0x00000040, count=1, Err=8c0000400001009f:4000080482 (read error: read ECC error))
-
-3) Nehalem specific Corrected Error memory counters
-
-   Nehalem have some registers to count memory errors. The driver uses those
-   registers to report Corrected Errors on devices with Registered Dimms.
-
-   However, those counters don't work with Unregistered Dimms. As the chipset
-   offers some counters that also work with UDIMMS (but with a worse level of
-   granularity than the default ones), the driver exposes those registers for
-   UDIMM memories.
-
-   They can be read by looking at the contents of all_channel_counts/
-
-   $ for i in /sys/devices/system/edac/mc/mc0/all_channel_counts/*; do echo $i; cat $i; done
-	/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm0
-	0
-	/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm1
-	0
-	/sys/devices/system/edac/mc/mc0/all_channel_counts/udimm2
-	0
-
-   What happens here is that errors on different csrows, but at the same
-   dimm number will increment the same counter.
-   So, in this memory mapping:
-	csrow0: channel 0, dimm0
-	csrow1: channel 0, dimm1
-	csrow2: channel 1, dimm0
-	csrow3: channel 2, dimm0
-   The hardware will increment udimm0 for an error at the first dimm at either
-	csrow0, csrow2  or csrow3;
-   The hardware will increment udimm1 for an error at the second dimm at either
-	csrow0, csrow2  or csrow3;
-   The hardware will increment udimm2 for an error at the third dimm at either
-	csrow0, csrow2  or csrow3;
-
-4) Standard error counters
-
-   The standard error counters are generated when an mcelog error is received
-   by the driver. Since, with udimm, this is counted by software, it is
-   possible that some errors could be lost. With rdimm's, they display the
-   contents of the registers

-The LogFS Flash Filesystem
-==========================
-
-Specification
-=============
-
-Superblocks
------------
-
-Two superblocks exist at the beginning and end of the filesystem.
-Each superblock is 256 Bytes large, with another 3840 Bytes reserved
-for future purposes, making a total of 4096 Bytes.
-
-Superblock locations may differ for MTD and block devices.  On MTD the
-first non-bad block contains a superblock in the first 4096 Bytes and
-the last non-bad block contains a superblock in the last 4096 Bytes.
-On block devices, the first 4096 Bytes of the device contain the first
-superblock and the last aligned 4096 Byte-block contains the second
-superblock.
-
-For the most part, the superblocks can be considered read-only.  They
-are written only to correct errors detected within the superblocks,
-move the journal and change the filesystem parameters through tunefs.
-As a result, the superblock does not contain any fields that require
-constant updates, like the amount of free space, etc.
-
-Segments
---------
-
-The space in the device is split up into equal-sized segments.
-Segments are the primary write unit of LogFS.  Within each segments,
-writes happen from front (low addresses) to back (high addresses.  If
-only a partial segment has been written, the segment number, the
-current position within and optionally a write buffer are stored in
-the journal.
-
-Segments are erased as a whole.  Therefore Garbage Collection may be
-required to completely free a segment before doing so.
-
-Journal
---------
-
-The journal contains all global information about the filesystem that
-is subject to frequent change.  At mount time, it has to be scanned
-for the most recent commit entry, which contains a list of pointers to
-all currently valid entries.
-
-Object Store
-------------
-
-All space except for the superblocks and journal is part of the object
-store.  Each segment contains a segment header and a number of
-objects, each consisting of the object header and the payload.
-Objects are either inodes, directory entries (dentries), file data
-blocks or indirect blocks.
-
-Levels
-------
-
-Garbage collection (GC) may fail if all data is written
-indiscriminately.  One requirement of GC is that data is separated
-roughly according to the distance between the tree root and the data.
-Effectively that means all file data is on level 0, indirect blocks
-are on levels 1, 2, 3 4 or 5 for 1x, 2x, 3x, 4x or 5x indirect blocks,
-respectively.  Inode file data is on level 6 for the inodes and 7-11
-for indirect blocks.
-
-Each segment contains objects of a single level only.  As a result,
-each level requires its own separate segment to be open for writing.
-
-Inode File
-----------
-
-All inodes are stored in a special file, the inode file.  Single
-exception is the inode file's inode (master inode) which for obvious
-reasons is stored in the journal instead.  Instead of data blocks, the
-leaf nodes of the inode files are inodes.
-
-Aliases
--------
-
-Writes in LogFS are done by means of a wandering tree.  A naïve
-implementation would require that for each write or a block, all
-parent blocks are written as well, since the block pointers have
-changed.  Such an implementation would not be very efficient.
-
-In LogFS, the block pointer changes are cached in the journal by means
-of alias entries.  Each alias consists of its logical address - inode
-number, block index, level and child number (index into block) - and
-the changed data.  Any 8-byte word can be changes in this manner.
-
-Currently aliases are used for block pointers, file size, file used
-bytes and the height of an inodes indirect tree.
-
-Segment Aliases
----------------
-
-Related to regular aliases, these are used to handle bad blocks.
-Initially, bad blocks are handled by moving the affected segment
-content to a spare segment and noting this move in the journal with a
-segment alias, a simple (to, from) tupel.  GC will later empty this
-segment and the alias can be removed again.  This is used on MTD only.
-
-Vim
----
-
-By cleverly predicting the life time of data, it is possible to
-separate long-living data from short-living data and thereby reduce
-the GC overhead later.  Each type of distinc life expectency (vim) can
-have a separate segment open for writing.  Each (level, vim) tupel can
-be open just once.  If an open segment with unknown vim is encountered
-at mount time, it is closed and ignored henceforth.
-
-Indirect Tree
--------------
-
-Inodes in LogFS are similar to FFS-style filesystems with direct and
-indirect block pointers.  One difference is that LogFS uses a single
-indirect pointer that can be either a 1x, 2x, etc. indirect pointer.
-A height field in the inode defines the height of the indirect tree
-and thereby the indirection of the pointer.
-
-Another difference is the addressing of indirect blocks.  In LogFS,
-the first 16 pointers in the first indirect block are left empty,
-corresponding to the 16 direct pointers in the inode.  In ext2 (maybe
-others as well) the first pointer in the first indirect block
-corresponds to logical block 12, skipping the 12 direct pointers.
-So where ext2 is using arithmetic to better utilize space, LogFS keeps
-arithmetic simple and uses compression to save space.
-
-Compression
------------
-
-Both file data and metadata can be compressed.  Compression for file
-data can be enabled with chattr +c and disabled with chattr -c.  Doing
-so has no effect on existing data, but new data will be stored
-accordingly.  New inodes will inherit the compression flag of the
-parent directory.
-
-Metadata is always compressed.  However, the space accounting ignores
-this and charges for the uncompressed size.  Failing to do so could
-result in GC failures when, after moving some data, indirect blocks
-compress worse than previously.  Even on a 100% full medium, GC may
-not consume any extra space, so the compression gains are lost space
-to the user.
-
-However, they are not lost space to the filesystem internals.  By
-cheating the user for those bytes, the filesystem gained some slack
-space and GC will run less often and faster.
-
-Garbage Collection and Wear Leveling
-------------------------------------
-
-Garbage collection is invoked whenever the number of free segments
-falls below a threshold.  The best (known) candidate is picked based
-on the least amount of valid data contained in the segment.  All
-remaining valid data is copied elsewhere, thereby invalidating it.
-
-The GC code also checks for aliases and writes then back if their
-number gets too large.
-
-Wear leveling is done by occasionally picking a suboptimal segment for
-garbage collection.  If a stale segments erase count is significantly
-lower than the active segments' erase counts, it will be picked.  Wear
-leveling is rate limited, so it will never monopolize the device for
-more than one segment worth at a time.
-
-Values for "occasionally", "significantly lower" are compile time
-constants.
-
-Hashed directories
-------------------
-
-To satisfy efficient lookup(), directory entries are hashed and
-located based on the hash.  In order to both support large directories
-and not be overly inefficient for small directories, several hash
-tables of increasing size are used.  For each table, the hash value
-modulo the table size gives the table index.
-
-Tables sizes are chosen to limit the number of indirect blocks with a
-fully populated table to 0, 1, 2 or 3 respectively.  So the first
-table contains 16 entries, the second 512-16, etc.
-
-The last table is special in several ways.  First its size depends on
-the effective 32bit limit on telldir/seekdir cookies.  Since logfs
-uses the upper half of the address space for indirect blocks, the size
-is limited to 2^31.  Secondly the table contains hash buckets with 16
-entries each.
-
-Using single-entry buckets would result in birthday "attacks".  At
-just 2^16 used entries, hash collisions would be likely (P >= 0.5).
-My math skills are insufficient to do the combinatorics for the 17x
-collisions necessary to overflow a bucket, but testing showed that in
-10,000 runs the lowest directory fill before a bucket overflow was
-188,057,130 entries with an average of 315,149,915 entries.  So for
-directory sizes of up to a million, bucket overflows should be
-virtually impossible under normal circumstances.
-
-With carefully chosen filenames, it is obviously possible to cause an
-overflow with just 21 entries (4 higher tables + 16 entries + 1).  So
-there may be a security concern if a malicious user has write access
-to a directory.
-
-Open For Discussion
-===================
-
-Device Address Space
---------------------
-
-A device address space is used for caching.  Both block devices and
-MTD provide functions to either read a single page or write a segment.
-Partial segments may be written for data integrity, but where possible
-complete segments are written for performance on simple block device
-flash media.
-
-Meta Inodes
------------
-
-Inodes are stored in the inode file, which is just a regular file for
-most purposes.  At umount time, however, the inode file needs to
-remain open until all dirty inodes are written.  So
-generic_shutdown_super() may not close this inode, but shouldn't
-complain about remaining inodes due to the inode file either.  Same
-goes for mapping inode of the device address space.
-
-Currently logfs uses a hack that essentially copies part of fs/inode.c
-code over.  A general solution would be preferred.
-
-Indirect block mapping
-----------------------
-
-With compression, the block device (or mapping inode) cannot be used
-to cache indirect blocks.  Some other place is required.  Currently
-logfs uses the top half of each inode's address space.  The low 8TB
-(on 32bit) are filled with file data, the high 8TB are used for
-indirect blocks.
-
-One problem is that 16TB files created on 64bit systems actually have
-data in the top 8TB.  But files >16TB would cause problems anyway, so
-only the limit has changed.

+Kernel driver tc654
+===================
+
+Supported chips:
+  * Microship TC654 and TC655

+
+Description
+-----------
+This driver implements support for the Microchip TC654 and TC655.
+
+The TC654 uses the 2-wire interface compatible with the SMBUS 2.0
+specification. The TC654 has two (2) inputs for measuring fan RPM and
+one (1) PWM output which can be used for fan control.
+
+Configuration Notes
+-------------------
+Ordinarily the pwm1_mode ABI is used for controlling the pwm output
+mode.  However, for this chip the output is always pwm, and the
+pwm1_mode determines if the pwm output is controlled via the pwm1 value
+or via the Vin analog input.
+
+
+Setting pwm1_mode to 1 will cause the pwm output to be driven based on
+the pwm1 value. Setting pwm1_mode to 0 will cause the pwm output to be
+driven based on the Vin input.

+Description
+-----------
+
+The Texas Instruments TMP108 implements one temperature sensor. An alert pin
+can be set when temperatures exceed minimum or maximum values plus or minus a
+hysteresis value. (This driver does not support interrupts for the alert pin,
+and the device runs in comparator mode.)
+
+The sensor is accurate to 0.75C over the range of -25 to +85 C, and to 1.0
+degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree. The
+operating temperature has a minimum of -55 C and a maximum of +150 C.
+Hysteresis values can be set to 0, 1, 2, or 4C.
+
+The TMP108 has a programmable update rate that can select between 8, 4, 1, and
+0.5 Hz.
+
+By default the TMP108 reads the temperature continuously. To conserve power,
+the TMP108 has a one-shot mode where the device is normally shut-down. When a
+one shot is requested the temperature is read, the result can be retrieved,
+and then the device is shut down automatically. (This driver only supports
+continuous mode.)
+
+The driver provides the common sysfs-interface for temperatures (see
+Documentation/hwmon/sysfs-interface under Temperatures).

+Userspace LEDs
+==============
+
+The uleds driver supports userspace LEDs. This can be useful for testing
+triggers and can also be used to implement virtual LEDs.
+
+
+Usage
+=====
+
+When the driver is loaded, a character device is created at /dev/uleds. To
+create a new LED class device, open /dev/uleds and write a uleds_user_dev
+structure to it (found in kernel public header file linux/uleds.h).
+
+    #define LED_MAX_NAME_SIZE 64
+
+    struct uleds_user_dev {
+        char name[LED_MAX_NAME_SIZE];
+    };
+
+A new LED class device will be created with the name given. The name can be
+any valid sysfs device node name, but consider using the LED class naming
+convention of "devicename:color:function".
+
+The current brightness is found by reading a single byte from the character
+device. Values are unsigned: 0 to 255. Reading will block until the brightness
+changes. The device node can also be polled to notify when the brightness value
+changes.
+
+The LED class device will be removed when the open file handle to /dev/uleds
+is closed.
+
+Multiple LED class devices are created by opening additional file handles to
+/dev/uleds.
+
+See tools/leds/uledmon.c for an example userspace program.

-	     Semantics and Behavior of Local Atomic Operations
-
-			    Mathieu Desnoyers
-
-
-	This document explains the purpose of the local atomic operations, how
-to implement them for any given architecture and shows how they can be used
-properly. It also stresses on the precautions that must be taken when reading
-those local variables across CPUs when the order of memory writes matters.
-
-Note that local_t based operations are not recommended for general kernel use.
-Please use the this_cpu operations instead unless there is really a special purpose.
-Most uses of local_t in the kernel have been replaced by this_cpu operations.
-this_cpu operations combine the relocation with the local_t like semantics in
-a single instruction and yield more compact and faster executing code.
-
-
-* Purpose of local atomic operations
-
-Local atomic operations are meant to provide fast and highly reentrant per CPU
-counters. They minimize the performance cost of standard atomic operations by
-removing the LOCK prefix and memory barriers normally required to synchronize
-across CPUs.
-
-Having fast per CPU atomic counters is interesting in many cases : it does not
-require disabling interrupts to protect from interrupt handlers and it permits
-coherent counters in NMI handlers. It is especially useful for tracing purposes
-and for various performance monitoring counters.
-
-Local atomic operations only guarantee variable modification atomicity wrt the
-CPU which owns the data. Therefore, care must taken to make sure that only one
-CPU writes to the local_t data. This is done by using per cpu data and making
-sure that we modify it from within a preemption safe context. It is however
-permitted to read local_t data from any CPU : it will then appear to be written
-out of order wrt other memory writes by the owner CPU.
-
-
-* Implementation for a given architecture
-
-It can be done by slightly modifying the standard atomic operations : only
-their UP variant must be kept. It typically means removing LOCK prefix (on
-i386 and x86_64) and any SMP synchronization barrier. If the architecture does
-not have a different behavior between SMP and UP, including asm-generic/local.h
-in your architecture's local.h is sufficient.
-
-The local_t type is defined as an opaque signed long by embedding an
-atomic_long_t inside a structure. This is made so a cast from this type to a
-long fails. The definition looks like :
-
-typedef struct { atomic_long_t a; } local_t;
-
-
-* Rules to follow when using local atomic operations
-
-- Variables touched by local ops must be per cpu variables.
-- _Only_ the CPU owner of these variables must write to them.
-- This CPU can use local ops from any context (process, irq, softirq, nmi, ...)
-  to update its local_t variables.
-- Preemption (or interrupts) must be disabled when using local ops in
-  process context to   make sure the process won't be migrated to a
-  different CPU between getting the per-cpu variable and doing the
-  actual local op.
-- When using local ops in interrupt context, no special care must be
-  taken on a mainline kernel, since they will run on the local CPU with
-  preemption already disabled. I suggest, however, to explicitly
-  disable preemption anyway to make sure it will still work correctly on
-  -rt kernels.
-- Reading the local cpu variable will provide the current copy of the
-  variable.
-- Reads of these variables can be done from any CPU, because updates to
-  "long", aligned, variables are always atomic. Since no memory
-  synchronization is done by the writer CPU, an outdated copy of the
-  variable can be read when reading some _other_ cpu's variables.
-
-
-* How to use local atomic operations
-
-#include <linux/percpu.h>
-#include <asm/local.h>
-
-static DEFINE_PER_CPU(local_t, counters) = LOCAL_INIT(0);
-
-
-* Counting
-
-Counting is done on all the bits of a signed long.
-
-In preemptible context, use get_cpu_var() and put_cpu_var() around local atomic
-operations : it makes sure that preemption is disabled around write access to
-the per cpu variable. For instance :
-
-	local_inc(&get_cpu_var(counters));
-	put_cpu_var(counters);
-
-If you are already in a preemption-safe context, you can use
-this_cpu_ptr() instead.
-
-	local_inc(this_cpu_ptr(&counters));
-
-
-
-* Reading the counters
-
-Those local counters can be read from foreign CPUs to sum the count. Note that
-the data seen by local_read across CPUs must be considered to be out of order
-relatively to other memory writes happening on the CPU that owns the data.
-
-	long sum = 0;
-	for_each_online_cpu(cpu)
-		sum += local_read(&per_cpu(counters, cpu));
-
-If you want to use a remote local_read to synchronize access to a resource
-between CPUs, explicit smp_wmb() and smp_rmb() memory barriers must be used
-respectively on the writer and the reader CPUs. It would be the case if you use

-This file is a registry of magic numbers which are in use.  When you
-add a magic number to a structure, you should also add it to this
-file, since it is best if the magic numbers used by various structures
-are unique.
-
-It is a *very* good idea to protect kernel data structures with magic
-numbers.  This allows you to check at run time whether (a) a structure
-has been clobbered, or (b) you've passed the wrong structure to a
-routine.  This last is especially useful --- particularly when you are
-passing pointers to structures via a void * pointer.  The tty code,
-for example, does this frequently to pass driver-specific and line
-discipline-specific structures back and forth.
-
-The way to use magic numbers is to declare then at the beginning of
-the structure, like so:
-
-struct tty_ldisc {
-	int	magic;
-	...
-};
-
-Please follow this discipline when you are adding future enhancements
-to the kernel!  It has saved me countless hours of debugging,
-especially in the screwy cases where an array has been overrun and
-structures following the array have been overwritten.  Using this
-discipline, these cases get detected quickly and safely.

+MIPI CSI-2
+==========
+
+CSI-2 is a data bus intended for transferring images from cameras to
+the host SoC. It is defined by the `MIPI alliance`_.
+
+.. _`MIPI alliance`: http://www.mipi.org/
+
+Transmitter drivers
+-------------------
+
+CSI-2 transmitter, such as a sensor or a TV tuner, drivers need to
+provide the CSI-2 receiver with information on the CSI-2 bus
+configuration. These include the V4L2_CID_LINK_FREQ and
+V4L2_CID_PIXEL_RATE controls and
+(:c:type:`v4l2_subdev_video_ops`->s_stream() callback). These
+interface elements must be present on the sub-device represents the
+CSI-2 transmitter.
+
+The V4L2_CID_LINK_FREQ control is used to tell the receiver driver the
+frequency (and not the symbol rate) of the link. The
+V4L2_CID_PIXEL_RATE is may be used by the receiver to obtain the pixel
+rate the transmitter uses. The
+:c:type:`v4l2_subdev_video_ops`->s_stream() callback provides an
+ability to start and stop the stream.
+
+The value of the V4L2_CID_PIXEL_RATE is calculated as follows::
+
+	pixel_rate = link_freq * 2 * nr_of_lanes / bits_per_sample
+
+where
+
+.. list-table:: variables in pixel rate calculation
+   :header-rows: 1
+
+   * - variable or constant
+     - description
+   * - link_freq
+     - The value of the V4L2_CID_LINK_FREQ integer64 menu item.
+   * - nr_of_lanes
+     - Number of data lanes used on the CSI-2 link. This can
+       be obtained from the OF endpoint configuration.
+   * - 2
+     - Two bits are transferred per clock cycle per lane.
+   * - bits_per_sample
+     - Number of bits per sample.
+
+The transmitter drivers must configure the CSI-2 transmitter to *LP-11
+mode* whenever the transmitter is powered on but not active. Some
+transmitters do this automatically but some have to be explicitly
+programmed to do so.
+
+Receiver drivers
+----------------
+
+Before the receiver driver may enable the CSI-2 transmitter by using
+the :c:type:`v4l2_subdev_video_ops`->s_stream(), it must have powered
+the transmitter up by using the
+:c:type:`v4l2_subdev_core_ops`->s_power() callback. This may take
+place either indirectly by using :c:func:`v4l2_pipeline_pm_use` or
+directly.

+	are processed differently: either value will match both possible replies.
+	The reason is that the ``CEC_MSG_INITIATE_ARC`` message is the only CEC

-	  ``timeout`` is 0, then don't wait for a reply but return after
-	  transmitting the message. Ignored by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
-	  The case where ``reply`` is 0 (this is the opcode for the Feature Abort
-	  message) and ``timeout`` is non-zero is specifically allowed to make it
-	  possible to send a message and wait up to ``timeout`` milliseconds for a
-	  Feature Abort reply. In this case ``rx_status`` will either be set

+HSV Formats
+***********
+
+These formats store the color information of the image
+in a geometrical representation. The colors are mapped into a
+cylinder, where the angle is the HUE, the height is the VALUE
+and the distance to the center is the SATURATION. This is a very
+useful format for image segmentation algorithms.

 Description
 ===========
 
-This format is similar to
-:ref:`V4L2_PIX_FMT_SBGGR8 <V4L2-PIX-FMT-SBGGR8>`, except each pixel
-has a depth of 16 bits. The least significant byte is stored at lower
-memory addresses (little-endian).
+These four pixel formats are raw sRGB / Bayer formats with 16 bits per
+sample. Each sample is stored in a 16-bit word. Each n-pixel row contains
+n/2 green samples and n/2 blue or red samples, with alternating red and blue
+rows. Bytes are stored in memory in little endian order. They are
+conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is
+an example of a small V4L2_PIX_FMT_SBGGR16 image:

 The following table lists existing packed Bayer formats. The data
 organization is given as an example for the first pixel only.

+.. it switches to long table, and there's no way to override it.

+Renesas R-Car Fine Display Processor (FDP1) Driver
+==================================================
+
+The R-Car FDP1 driver implements driver-specific controls as follows.
+
+``V4L2_CID_DEINTERLACING_MODE (menu)``
+    The video deinterlacing mode (such as Bob, Weave, ...). The R-Car FDP1
+    driver implements the following modes.
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+    :widths:       1 4
+
+    * - ``"Progressive" (0)``
+      - The input image video stream is progressive (not interlaced). No
+        deinterlacing is performed. Apart from (optional) format and encoding
+        conversion output frames are identical to the input frames.
+    * - ``"Adaptive 2D/3D" (1)``
+      - Motion adaptive version of 2D and 3D deinterlacing. Use 3D deinterlacing
+        in the presence of fast motion and 2D deinterlacing with diagonal
+        interpolation otherwise.
+    * - ``"Fixed 2D" (2)``

+(RG)MII/electrical interface considerations
+
+ The Reduced Gigabit Medium Independent Interface (RGMII) is a 12-pin
+ electrical signal interface using a synchronous 125Mhz clock signal and several
+ data lines. Due to this design decision, a 1.5ns to 2ns delay must be added
+ between the clock line (RXC or TXC) and the data lines to let the PHY (clock
+ sink) have enough setup and hold times to sample the data lines correctly. The
+ PHY library offers different types of PHY_INTERFACE_MODE_RGMII* values to let
+ the PHY driver and optionally the MAC driver, implement the required delay. The
+ values of phy_interface_t must be understood from the perspective of the PHY
+ device itself, leading to the following:
+
+ * PHY_INTERFACE_MODE_RGMII: the PHY is not responsible for inserting any
+   internal delay by itself, it assumes that either the Ethernet MAC (if capable
+   or the PCB traces) insert the correct 1.5-2ns delay
+
+ * PHY_INTERFACE_MODE_RGMII_TXID: the PHY should insert an internal delay
+   for the transmit data lines (TXD[3:0]) processed by the PHY device
+
+ * PHY_INTERFACE_MODE_RGMII_RXID: the PHY should insert an internal delay
+   for the receive data lines (RXD[3:0]) processed by the PHY device
+
+ * PHY_INTERFACE_MODE_RGMII_ID: the PHY should insert internal delays for
+   both transmit AND receive data lines from/to the PHY device
+
+ Whenever possible, use the PHY side RGMII delay for these reasons:
+
+ * PHY devices may offer sub-nanosecond granularity in how they allow a
+   receiver/transmitter side delay (e.g: 0.5, 1.0, 1.5ns) to be specified. Such
+   precision may be required to account for differences in PCB trace lengths
+
+ * PHY devices are typically qualified for a large range of applications
+   (industrial, medical, automotive...), and they provide a constant and
+   reliable delay across temperature/pressure/voltage ranges
+
+ * PHY device drivers in PHYLIB being reusable by nature, being able to
+   configure correctly a specified delay enables more designs with similar delay
+   requirements to be operate correctly
+
+ For cases where the PHY is not capable of providing this delay, but the
+ Ethernet MAC driver is capable of doing so, the correct phy_interface_t value
+ should be PHY_INTERFACE_MODE_RGMII, and the Ethernet MAC driver should be
+ configured correctly in order to provide the required transmit and/or receive
+ side delay from the perspective of the PHY device. Conversely, if the Ethernet
+ MAC driver looks at the phy_interface_t value, for any other mode but
+ PHY_INTERFACE_MODE_RGMII, it should make sure that the MAC-level delays are
+ disabled.
+
+ In case neither the Ethernet MAC, nor the PHY are capable of providing the
+ required delays, as defined per the RGMII standard, several options may be
+ available:
+
+ * Some SoCs may offer a pin pad/mux/controller capable of configuring a given
+   set of pins'strength, delays, and voltage; and it may be a suitable
+   option to insert the expected 2ns RGMII delay.
+
+ * Modifying the PCB design to include a fixed delay (e.g: using a specifically
+   designed serpentine), which may not require software configuration at all.
+
+Common problems with RGMII delay mismatch
+
+ When there is a RGMII delay mismatch between the Ethernet MAC and the PHY, this
+ will most likely result in the clock and data line signals to be unstable when
+ the PHY or MAC take a snapshot of these signals to translate them into logical
+ 1 or 0 states and reconstruct the data being transmitted/received. Typical
+ symptoms include:
+
+ * Transmission/reception partially works, and there is frequent or occasional
+   packet loss observed
+
+ * Ethernet MAC may report some or all packets ingressing with a FCS/CRC error,
+   or just discard them all
+
+ * Switching to lower speeds such as 10/100Mbits/sec makes the problem go away
+   (since there is enough setup/hold time in that case)

-NOTE: ksymoops is useless on 2.6.  Please use the Oops in its original format
-(from dmesg, etc).  Ignore any references in this or other docs to "decoding
-the Oops" or "running it through ksymoops".  If you post an Oops from 2.6 that
-has been run through ksymoops, people will just tell you to repost it.
-
-Quick Summary
--------------
-
-Find the Oops and send it to the maintainer of the kernel area that seems to be
-involved with the problem.  Don't worry too much about getting the wrong person.
-If you are unsure send it to the person responsible for the code relevant to
-what you were doing.  If it occurs repeatably try and describe how to recreate
-it.  That's worth even more than the oops.
-
-If you are totally stumped as to whom to send the report, send it to 
-linux-kernel@vger.kernel.org. Thanks for your help in making Linux as
-stable as humanly possible.
-
-Where is the Oops?
-----------------------
-
-Normally the Oops text is read from the kernel buffers by klogd and
-handed to syslogd which writes it to a syslog file, typically
-/var/log/messages (depends on /etc/syslog.conf).  Sometimes klogd dies,
-in which case you can run dmesg > file to read the data from the kernel
-buffers and save it.  Or you can cat /proc/kmsg > file, however you
-have to break in to stop the transfer, kmsg is a "never ending file".
-If the machine has crashed so badly that you cannot enter commands or
-the disk is not available then you have three options :-
-
-(1) Hand copy the text from the screen and type it in after the machine
-    has restarted.  Messy but it is the only option if you have not
-    planned for a crash. Alternatively, you can take a picture of
-    the screen with a digital camera - not nice, but better than
-    nothing.  If the messages scroll off the top of the console, you
-    may find that booting with a higher resolution (eg, vga=791)
-    will allow you to read more of the text. (Caveat: This needs vesafb,
-    so won't help for 'early' oopses)
-
-(2) Boot with a serial console (see Documentation/serial-console.txt),
-    run a null modem to a second machine and capture the output there
-    using your favourite communication program.  Minicom works well.
-
-(3) Use Kdump (see Documentation/kdump/kdump.txt),
-    extract the kernel ring buffer from old memory with using dmesg
-    gdbmacro in Documentation/kdump/gdbmacros.txt.

-Full Information
-----------------
-
-NOTE: the message from Linus below applies to 2.4 kernel.  I have preserved it
-for historical reasons, and because some of the information in it still
-applies.  Especially, please ignore any references to ksymoops. 
-
-From: Linus Torvalds <torvalds@osdl.org>
-
-How to track down an Oops.. [originally a mail to linux-kernel]
-
-The main trick is having 5 years of experience with those pesky oops 
-messages ;-)
-
-Actually, there are things you can do that make this easier. I have two 
-separate approaches:
-
-	gdb /usr/src/linux/vmlinux
-	gdb> disassemble <offending_function>
-
-That's the easy way to find the problem, at least if the bug-report is 
-well made (like this one was - run through ksymoops to get the 
-information of which function and the offset in the function that it 
-happened in).
-
-Oh, it helps if the report happens on a kernel that is compiled with the 
-same compiler and similar setups.
-
-The other thing to do is disassemble the "Code:" part of the bug report: 
-ksymoops will do this too with the correct tools, but if you don't have
-the tools you can just do a silly program:
-
-	char str[] = "\xXX\xXX\xXX...";
-	main(){}
-
-and compile it with gcc -g and then do "disassemble str" (where the "XX" 
-stuff are the values reported by the Oops - you can just cut-and-paste 
-and do a replace of spaces to "\x" - that's what I do, as I'm too lazy 
-to write a program to automate this all).
-
-Alternatively, you can use the shell script in scripts/decodecode.
-Its usage is:  decodecode < oops.txt
-
-The hex bytes that follow "Code:" may (in some architectures) have a series
-of bytes that precede the current instruction pointer as well as bytes at and
-following the current instruction pointer.  In some cases, one instruction
-byte or word is surrounded by <> or (), as in "<86>" or "(f00d)".  These
-<> or () markings indicate the current instruction pointer.  Example from
-i386, split into multiple lines for readability:
-
-Code: f9 0f 8d f9 00 00 00 8d 42 0c e8 dd 26 11 c7 a1 60 ea 2b f9 8b 50 08 a1
-64 ea 2b f9 8d 34 82 8b 1e 85 db 74 6d 8b 15 60 ea 2b f9 <8b> 43 04 39 42 54
-7e 04 40 89 42 54 8b 43 04 3b 05 00 f6 52 c0
-
-Finally, if you want to see where the code comes from, you can do
-
-	cd /usr/src/linux
-	make fs/buffer.s 	# or whatever file the bug happened in
-
-and then you get a better idea of what happens than with the gdb 
-disassembly.
-
-Now, the trick is just then to combine all the data you have: the C 
-sources (and general knowledge of what it _should_ do), the assembly 
-listing and the code disassembly (and additionally the register dump you 
-also get from the "oops" message - that can be useful to see _what_ the 
-corrupted pointers were, and when you have the assembler listing you can 
-also match the other registers to whatever C expressions they were used 
-for).
-
-Essentially, you just look at what doesn't match (in this case it was the 
-"Code" disassembly that didn't match with what the compiler generated). 
-Then you need to find out _why_ they don't match. Often it's simple - you 
-see that the code uses a NULL pointer and then you look at the code and 
-wonder how the NULL pointer got there, and if it's a valid thing to do 
-you just check against it..
-
-Now, if somebody gets the idea that this is time-consuming and requires 
-some small amount of concentration, you're right. Which is why I will 
-mostly just ignore any panic reports that don't have the symbol table 
-info etc looked up: it simply gets too hard to look it up (I have some 
-programs to search for specific patterns in the kernel code segment, and 
-sometimes I have been able to look up those kinds of panics too, but 
-that really requires pretty good knowledge of the kernel just to be able 
-to pick out the right sequences etc..)
-
-_Sometimes_ it happens that I just see the disassembled code sequence 
-from the panic, and I know immediately where it's coming from. That's when 
-I get worried that I've been doing this for too long ;-)

----------------------------------------------------------------------------
-Notes on Oops tracing with klogd:
-
-In order to help Linus and the other kernel developers there has been
-substantial support incorporated into klogd for processing protection
-faults.  In order to have full support for address resolution at least
-version 1.3-pl3 of the sysklogd package should be used.
-
-When a protection fault occurs the klogd daemon automatically
-translates important addresses in the kernel log messages to their
-symbolic equivalents.  This translated kernel message is then
-forwarded through whatever reporting mechanism klogd is using.  The
-protection fault message can be simply cut out of the message files
-and forwarded to the kernel developers.
-
-Two types of address resolution are performed by klogd.  The first is
-static translation and the second is dynamic translation.  Static
-translation uses the System.map file in much the same manner that
-ksymoops does.  In order to do static translation the klogd daemon
-must be able to find a system map file at daemon initialization time.
-See the klogd man page for information on how klogd searches for map
-files.
-
-Dynamic address translation is important when kernel loadable modules
-are being used.  Since memory for kernel modules is allocated from the
-kernel's dynamic memory pools there are no fixed locations for either
-the start of the module or for functions and symbols in the module.
-
-The kernel supports system calls which allow a program to determine
-which modules are loaded and their location in memory.  Using these
-system calls the klogd daemon builds a symbol table which can be used
-to debug a protection fault which occurs in a loadable kernel module.
-
-At the very minimum klogd will provide the name of the module which
-generated the protection fault.  There may be additional symbolic
-information available if the developer of the loadable module chose to
-export symbol information from the module.
-
-Since the kernel module environment can be dynamic there must be a
-mechanism for notifying the klogd daemon when a change in module
-environment occurs.  There are command line options available which
-allow klogd to signal the currently executing daemon that symbol
-information should be refreshed.  See the klogd manual page for more
-information.
-
-A patch is included with the sysklogd distribution which modifies the
-modules-2.0.0 package to automatically signal klogd whenever a module
-is loaded or unloaded.  Applying this patch provides essentially
-seamless support for debugging protection faults which occur with
-kernel loadable modules.
-
-The following is an example of a protection fault in a loadable module
-processed by klogd:

-Tainted kernels:
-
-Some oops reports contain the string 'Tainted: ' after the program
-counter. This indicates that the kernel has been tainted by some
-mechanism.  The string is followed by a series of position-sensitive
-characters, each representing a particular tainted value.
-
-  1: 'G' if all modules loaded have a GPL or compatible license, 'P' if
-     any proprietary module has been loaded.  Modules without a
-     MODULE_LICENSE or with a MODULE_LICENSE that is not recognised by
-     insmod as GPL compatible are assumed to be proprietary.
-
-  2: 'F' if any module was force loaded by "insmod -f", ' ' if all
-     modules were loaded normally.
-
-  3: 'S' if the oops occurred on an SMP kernel running on hardware that
-     hasn't been certified as safe to run multiprocessor.
-     Currently this occurs only on various Athlons that are not
-     SMP capable.
-
-  4: 'R' if a module was force unloaded by "rmmod -f", ' ' if all
-     modules were unloaded normally.
-
-  5: 'M' if any processor has reported a Machine Check Exception,
-     ' ' if no Machine Check Exceptions have occurred.
-
-  6: 'B' if a page-release function has found a bad page reference or
-     some unexpected page flags.
-
-  7: 'U' if a user or user application specifically requested that the
-     Tainted flag be set, ' ' otherwise.
-
-  8: 'D' if the kernel has died recently, i.e. there was an OOPS or BUG.
-
-  9: 'A' if the ACPI table has been overridden.
-
- 10: 'W' if a warning has previously been issued by the kernel.
-     (Though some warnings may set more specific taint flags.)
-
- 11: 'C' if a staging driver has been loaded.
-
- 12: 'I' if the kernel is working around a severe bug in the platform
-     firmware (BIOS or similar).
-
- 13: 'O' if an externally-built ("out-of-tree") module has been loaded.
-
- 14: 'E' if an unsigned module has been loaded in a kernel supporting
-     module signature.
-
- 15: 'L' if a soft lockup has previously occurred on the system.
-
- 16: 'K' if the kernel has been live patched.
-
-The primary reason for the 'Tainted: ' string is to tell kernel
-debuggers if this is a clean kernel or if anything unusual has
-occurred.  Tainting is permanent: even if an offending module is
-unloaded, the tainted value remains to indicate that the kernel is not
-trustworthy.

-The `parport' code provides parallel-port support under Linux.  This
-includes the ability to share one port between multiple device
-drivers.
-
-You can pass parameters to the parport code to override its automatic
-detection of your hardware.  This is particularly useful if you want
-to use IRQs, since in general these can't be autoprobed successfully.
-By default IRQs are not used even if they _can_ be probed.  This is
-because there are a lot of people using the same IRQ for their
-parallel port and a sound card or network card.
-
-The parport code is split into two parts: generic (which deals with
-port-sharing) and architecture-dependent (which deals with actually
-using the port).
-
-
-Parport as modules
-==================
-
-If you load the parport code as a module, say
-
-	# insmod parport
-
-to load the generic parport code.  You then must load the
-architecture-dependent code with (for example):
-
-	# insmod parport_pc io=0x3bc,0x378,0x278 irq=none,7,auto
-
-to tell the parport code that you want three PC-style ports, one at
-0x3bc with no IRQ, one at 0x378 using IRQ 7, and one at 0x278 with an
-auto-detected IRQ.  Currently, PC-style (parport_pc), Sun `bpp',
-Amiga, Atari, and MFC3 hardware is supported.
-
-PCI parallel I/O card support comes from parport_pc.  Base I/O
-addresses should not be specified for supported PCI cards since they
-are automatically detected.
-
-
-modprobe
---------
-
-If you use modprobe , you will find it useful to add lines as below to a
-configuration file in /etc/modprobe.d/ directory:.
-
-	alias parport_lowlevel parport_pc
-	options parport_pc io=0x378,0x278 irq=7,auto
-
-modprobe will load parport_pc (with the options "io=0x378,0x278 irq=7,auto")
-whenever a parallel port device driver (such as lp) is loaded.
-
-Note that these are example lines only!  You shouldn't in general need
-to specify any options to parport_pc in order to be able to use a
-parallel port.
-
-
-Parport probe [optional]
--------------
-
-In 2.2 kernels there was a module called parport_probe, which was used
-for collecting IEEE 1284 device ID information.  This has now been
-enhanced and now lives with the IEEE 1284 support.  When a parallel
-port is detected, the devices that are connected to it are analysed,
-and information is logged like this:
-
-	parport0: Printer, BJC-210 (Canon)
-
-The probe information is available from files in /proc/sys/dev/parport/.
-
-
-Parport linked into the kernel statically
-=========================================
-
-If you compile the parport code into the kernel, then you can use
-kernel boot parameters to get the same effect.  Add something like the
-following to your LILO command line:
-
-	parport=0x3bc parport=0x378,7 parport=0x278,auto,nofifo
-
-You can have many `parport=...' statements, one for each port you want
-to add.  Adding `parport=0' to the kernel command-line will disable
-parport support entirely.  Adding `parport=auto' to the kernel
-command-line will make parport use any IRQ lines or DMA channels that
-it auto-detects.
-
-
-Files in /proc
-==============
-
-If you have configured the /proc filesystem into your kernel, you will
-see a new directory entry: /proc/sys/dev/parport.  In there will be a
-directory entry for each parallel port for which parport is
-configured.  In each of those directories are a collection of files
-describing that parallel port.
-
-The /proc/sys/dev/parport directory tree looks like:
-
-parport
-|-- default
-|   |-- spintime
-|   `-- timeslice
-|-- parport0
-|   |-- autoprobe

-File:		Contents:
-
-devices/active	A list of the device drivers using that port.  A "+"
-		will appear by the name of the device currently using
-		the port (it might not appear against any).  The
-		string "none" means that there are no device drivers
-		using that port.
-
-base-addr	Parallel port's base address, or addresses if the port
-		has more than one in which case they are separated
-		with tabs.  These values might not have any sensible
-		meaning for some ports.
-
-irq		Parallel port's IRQ, or -1 if none is being used.
-
-dma		Parallel port's DMA channel, or -1 if none is being
-		used.
-
-modes		Parallel port's hardware modes, comma-separated,
-		meaning:
-
-		PCSPP		PC-style SPP registers are available.
-		TRISTATE	Port is bidirectional.
-		COMPAT		Hardware acceleration for printers is
-				available and will be used.
-		EPP		Hardware acceleration for EPP protocol
-				is available and will be used.
-		ECP		Hardware acceleration for ECP protocol
-				is available and will be used.
-		DMA		DMA is available and will be used.
-
-		Note that the current implementation will only take
-		advantage of COMPAT and ECP modes if it has an IRQ
-		line to use.
-
-autoprobe	Any IEEE-1284 device ID information that has been
-		acquired from the (non-IEEE 1284.3) device.
-
-autoprobe[0-3]	IEEE 1284 device ID information retrieved from
-		daisy-chain devices that conform to IEEE 1284.3.
-
-spintime	The number of microseconds to busy-loop while waiting
-		for the peripheral to respond.  You might find that
-		adjusting this improves performance, depending on your
-		peripherals.  This is a port-wide setting, i.e. it
-		applies to all devices on a particular port.
-
-timeslice	The number of milliseconds that a device driver is
-		allowed to keep a port claimed for.  This is advisory,
-		and driver can ignore it if it must.
-
-default/*	The defaults for spintime and timeslice. When a new
-		port is	registered, it picks up the default spintime.
-		When a new device is registered, it picks up the
-		default timeslice.
-
-Device drivers
-==============
-
-Once the parport code is initialised, you can attach device drivers to
-specific ports.  Normally this happens automatically; if the lp driver
-is loaded it will create one lp device for each port found.  You can
-override this, though, by using parameters either when you load the lp
-driver:
-
-	# insmod lp parport=0,2
-
-or on the LILO command line:
-
-	lp=parport0 lp=parport2
-
-Both the above examples would inform lp that you want /dev/lp0 to be
-the first parallel port, and /dev/lp1 to be the _third_ parallel port,
-with no lp device associated with the second port (parport1).  Note
-that this is different to the way older kernels worked; there used to
-be a static association between the I/O port address and the device
-name, so /dev/lp0 was always the port at 0x3bc.  This is no longer the
-case - if you only have one port, it will default to being /dev/lp0,
-regardless of base address.
-
-Also:
-
- * If you selected the IEEE 1284 support at compile time, you can say
-   `lp=auto' on the kernel command line, and lp will create devices
-   only for those ports that seem to have printers attached.
-
- * If you give PLIP the `timid' parameter, either with `plip=timid' on
-   the command line, or with `insmod plip timid=1' when using modules,
-   it will avoid any ports that seem to be in use by other devices.
-
- * IRQ autoprobing works only for a few port types at the moment.
-
-Reporting printer problems with parport
-=======================================
-
-If you are having problems printing, please go through these steps to
-try to narrow down where the problem area is.
-
-When reporting problems with parport, really you need to give all of
-the messages that parport_pc spits out when it initialises.  There are
-several code paths:
-
-o polling
-o interrupt-driven, protocol in software
-o interrupt-driven, protocol in hardware using PIO
-o interrupt-driven, protocol in hardware using DMA
-
-The kernel messages that parport_pc logs give an indication of which
-code path is being used. (They could be a lot better actually..)
-
-For normal printer protocol, having IEEE 1284 modes enabled or not
-should not make a difference.

+
+Kernel compilation
+******************
+
+GCC
+---
+
+The gcc version requirements may vary depending on the type of CPU in your
+computer.
+
+Make
+----
+
+You will need GNU make 3.80 or later to build the kernel.
+
+Binutils
+--------
+
+Linux on IA-32 has recently switched from using ``as86`` to using ``gas`` for
+assembling the 16-bit boot code, removing the need for ``as86`` to compile
+your kernel.  This change does, however, mean that you need a recent
+release of binutils.
+
+Perl
+----
+
+You will need perl 5 and the following modules: ``Getopt::Long``,
+``Getopt::Std``, ``File::Basename``, and ``File::Find`` to build the kernel.
+
+BC
+--
+
+You will need bc to build kernels 3.10 and higher
+
+
+OpenSSL
+-------
+
+Module signing and external certificate handling use the OpenSSL program and
+crypto library to do key creation and signature generation.
+
+You will need openssl to build kernels 3.7 and higher if module signing is
+enabled.  You will also need openssl development packages to build kernels 4.3
+and higher.
+
+
+System utilities
+****************
+
+Architectural changes
+---------------------
+
+DevFS has been obsoleted in favour of udev
+(http://www.kernel.org/pub/linux/utils/kernel/hotplug/)
+
+32-bit UID support is now in place.  Have fun!
+
+Linux documentation for functions is transitioning to inline
+documentation via specially-formatted comments near their
+definitions in the source.  These comments can be combined with the
+SGML templates in the Documentation/DocBook directory to make DocBook
+files, which can then be converted by DocBook stylesheets to PostScript,
+HTML, PDF files, and several other formats.  In order to convert from
+DocBook format to a format of your choice, you'll need to install Jade as
+well as the desired DocBook stylesheets.
+
+Util-linux
+----------
+
+New versions of util-linux provide ``fdisk`` support for larger disks,
+support new options to mount, recognize more supported partition
+types, have a fdformat which works with 2.4 kernels, and similar goodies.
+You'll probably want to upgrade.
+
+Ksymoops
+--------
+
+If the unthinkable happens and your kernel oopses, you may need the
+ksymoops tool to decode it, but in most cases you don't.
+It is generally preferred to build the kernel with ``CONFIG_KALLSYMS`` so
+that it produces readable dumps that can be used as-is (this also
+produces better output than ksymoops).  If for some reason your kernel
+is not build with ``CONFIG_KALLSYMS`` and you have no way to rebuild and
+reproduce the Oops with that option, then you can still decode that Oops
+with ksymoops.
+
+Module-Init-Tools
+-----------------
+
+A new module loader is now in the kernel that requires ``module-init-tools``
+to use.  It is backward compatible with the 2.4.x series kernels.
+
+Mkinitrd
+--------
+
+These changes to the ``/lib/modules`` file tree layout also require that
+mkinitrd be upgraded.
+
+E2fsprogs
+---------
+
+The latest version of ``e2fsprogs`` fixes several bugs in fsck and
+debugfs.  Obviously, it's a good idea to upgrade.
+
+JFSutils
+--------
+
+The ``jfsutils`` package contains the utilities for the file system.
+The following utilities are available:
+
+- ``fsck.jfs`` - initiate replay of the transaction log, and check
+  and repair a JFS formatted partition.
+
+- ``mkfs.jfs`` - create a JFS formatted partition.
+
+- other file system utilities are also available in this package.
+
+Reiserfsprogs
+-------------
+
+The reiserfsprogs package should be used for reiserfs-3.6.x
+(Linux kernels 2.4.x). It is a combined package and contains working
+versions of ``mkreiserfs``, ``resize_reiserfs``, ``debugreiserfs`` and
+``reiserfsck``. These utils work on both i386 and alpha platforms.
+
+Xfsprogs
+--------
+
+The latest version of ``xfsprogs`` contains ``mkfs.xfs``, ``xfs_db``, and the
+``xfs_repair`` utilities, among others, for the XFS filesystem.  It is
+architecture independent and any version from 2.0.0 onward should
+work correctly with this version of the XFS kernel code (2.6.0 or
+later is recommended, due to some significant improvements).
+
+PCMCIAutils
+-----------
+
+PCMCIAutils replaces ``pcmcia-cs``. It properly sets up
+PCMCIA sockets at system startup and loads the appropriate modules
+for 16-bit PCMCIA devices if the kernel is modularized and the hotplug
+subsystem is used.
+
+Quota-tools
+-----------
+
+Support for 32 bit uid's and gid's is required if you want to use
+the newer version 2 quota format.  Quota-tools version 3.07 and
+newer has this support.  Use the recommended version or newer
+from the table above.
+
+Intel IA32 microcode
+--------------------
+
+A driver has been added to allow updating of Intel IA32 microcode,
+accessible as a normal (misc) character device.  If you are not using
+udev you may need to::
+
+  mkdir /dev/cpu
+  mknod /dev/cpu/microcode c 10 184
+  chmod 0644 /dev/cpu/microcode
+
+as root before you can use this.  You'll probably also want to
+get the user-space microcode_ctl utility to use with this.
+
+udev
+----
+
+``udev`` is a userspace application for populating ``/dev`` dynamically with
+only entries for devices actually present. ``udev`` replaces the basic
+functionality of devfs, while allowing persistent device naming for
+devices.
+
+FUSE
+----
+
+Needs libfuse 2.4.0 or later.  Absolute minimum is 2.3.0 but mount
+options ``direct_io`` and ``kernel_cache`` won't work.
+
+Networking
+**********
+
+General changes
+---------------
+
+If you have advanced network configuration needs, you should probably
+consider using the network tools from ip-route2.
+
+Packet Filter / NAT
+-------------------
+The packet filtering and NAT code uses the same tools like the previous 2.4.x
+kernel series (iptables).  It still includes backwards-compatibility modules
+for 2.2.x-style ipchains and 2.0.x-style ipfwadm.
+
+PPP
+---
+
+The PPP driver has been restructured to support multilink and to
+enable it to operate over diverse media layers.  If you use PPP,
+upgrade pppd to at least 2.4.0.
+
+If you are not using udev, you must have the device file /dev/ppp
+which can be made by::
+
+  mknod /dev/ppp c 108 0
+
+as root.
+
+Isdn4k-utils
+------------
+
+Due to changes in the length of the phone number field, isdn4k-utils
+needs to be recompiled or (preferably) upgraded.
+
+NFS-utils
+---------
+
+In ancient (2.4 and earlier) kernels, the nfs server needed to know
+about any client that expected to be able to access files via NFS.  This
+information would be given to the kernel by ``mountd`` when the client
+mounted the filesystem, or by ``exportfs`` at system startup.  exportfs
+would take information about active clients from ``/var/lib/nfs/rmtab``.
+
+This approach is quite fragile as it depends on rmtab being correct
+which is not always easy, particularly when trying to implement
+fail-over.  Even when the system is working well, ``rmtab`` suffers from
+getting lots of old entries that never get removed.
+
+With modern kernels we have the option of having the kernel tell mountd
+when it gets a request from an unknown host, and mountd can give
+appropriate export information to the kernel.  This removes the
+dependency on ``rmtab`` and means that the kernel only needs to know about
+currently active clients.
+
+To enable this new functionality, you need to::
+
+  mount -t nfsd nfsd /proc/fs/nfsd
+
+before running exportfs or mountd.  It is recommended that all NFS
+services be protected from the internet-at-large by a firewall where
+that is possible.
+
+mcelog
+------
+
+On x86 kernels the mcelog utility is needed to process and log machine check
+events when ``CONFIG_X86_MCE`` is enabled. Machine check events are errors
+reported by the CPU. Processing them is strongly encouraged.
+
+Kernel documentation
+********************
+
+Sphinx
+------
+
+The ReST markups currently used by the Documentation/ files are meant to be
+built with ``Sphinx`` version 1.2 or upper. If you're desiring to build
+PDF outputs, it is recommended to use version 1.4.6.
+
+.. note::
+
+  Please notice that, for PDF and LaTeX output, you'll also need ``XeLaTeX``
+  version 3.14159265. Depending on the distribution, you may also need
+  to install a series of ``texlive`` packages that provide the minimal
+  set of functionalities required for ``XeLaTex`` to work.
+
+Other tools
+-----------
+
+In order to produce documentation from DocBook, you'll also need ``xmlto``.
+Please notice, however, that we're currently migrating all documents to use
+``Sphinx``.

+.. _codingstyle:
+
+Linux kernel coding style
+=========================
+
+This is a short document describing the preferred coding style for the
+linux kernel.  Coding style is very personal, and I won't **force** my
+views on anybody, but this is what goes for anything that I have to be
+able to maintain, and I'd prefer it for most other things too.  Please
+at least consider the points made here.
+
+First off, I'd suggest printing out a copy of the GNU coding standards,
+and NOT read it.  Burn them, it's a great symbolic gesture.
+
+Anyway, here goes:
+
+
+1) Indentation
+--------------
+
+Tabs are 8 characters, and thus indentations are also 8 characters.
+There are heretic movements that try to make indentations 4 (or even 2!)
+characters deep, and that is akin to trying to define the value of PI to
+be 3.
+
+Rationale: The whole idea behind indentation is to clearly define where
+a block of control starts and ends.  Especially when you've been looking
+at your screen for 20 straight hours, you'll find it a lot easier to see
+how the indentation works if you have large indentations.
+
+Now, some people will claim that having 8-character indentations makes
+the code move too far to the right, and makes it hard to read on a
+80-character terminal screen.  The answer to that is that if you need
+more than 3 levels of indentation, you're screwed anyway, and should fix
+your program.
+
+In short, 8-char indents make things easier to read, and have the added
+benefit of warning you when you're nesting your functions too deep.
+Heed that warning.
+
+The preferred way to ease multiple indentation levels in a switch statement is
+to align the ``switch`` and its subordinate ``case`` labels in the same column
+instead of ``double-indenting`` the ``case`` labels.  E.g.:
+
+.. code-block:: c
+
+	switch (suffix) {
+	case 'G':
+	case 'g':
+		mem <<= 30;
+		break;
+	case 'M':
+	case 'm':
+		mem <<= 20;
+		break;
+	case 'K':
+	case 'k':
+		mem <<= 10;
+		/* fall through */
+	default:
+		break;
+	}
+
+Don't put multiple statements on a single line unless you have
+something to hide:
+
+.. code-block:: c
+
+	if (condition) do_this;
+	  do_something_everytime;
+
+Don't put multiple assignments on a single line either.  Kernel coding style
+is super simple.  Avoid tricky expressions.
+
+Outside of comments, documentation and except in Kconfig, spaces are never
+used for indentation, and the above example is deliberately broken.
+
+Get a decent editor and don't leave whitespace at the end of lines.
+
+
+2) Breaking long lines and strings
+----------------------------------
+
+Coding style is all about readability and maintainability using commonly
+available tools.
+
+The limit on the length of lines is 80 columns and this is a strongly
+preferred limit.
+
+Statements longer than 80 columns will be broken into sensible chunks, unless
+exceeding 80 columns significantly increases readability and does not hide
+information. Descendants are always substantially shorter than the parent and
+are placed substantially to the right. The same applies to function headers
+with a long argument list. However, never break user-visible strings such as
+printk messages, because that breaks the ability to grep for them.
+
+
+3) Placing Braces and Spaces
+----------------------------
+
+The other issue that always comes up in C styling is the placement of
+braces.  Unlike the indent size, there are few technical reasons to
+choose one placement strategy over the other, but the preferred way, as
+shown to us by the prophets Kernighan and Ritchie, is to put the opening
+brace last on the line, and put the closing brace first, thusly:
+
+.. code-block:: c
+
+	if (x is true) {
+		we do y
+	}
+
+This applies to all non-function statement blocks (if, switch, for,
+while, do).  E.g.:
+
+.. code-block:: c
+
+	switch (action) {
+	case KOBJ_ADD:
+		return "add";
+	case KOBJ_REMOVE:
+		return "remove";
+	case KOBJ_CHANGE:
+		return "change";
+	default:
+		return NULL;
+	}
+
+However, there is one special case, namely functions: they have the
+opening brace at the beginning of the next line, thus:
+
+.. code-block:: c
+
+	int function(int x)
+	{
+		body of function
+	}
+
+Heretic people all over the world have claimed that this inconsistency
+is ...  well ...  inconsistent, but all right-thinking people know that
+(a) K&R are **right** and (b) K&R are right.  Besides, functions are
+special anyway (you can't nest them in C).
+
+Note that the closing brace is empty on a line of its own, **except** in
+the cases where it is followed by a continuation of the same statement,
+ie a ``while`` in a do-statement or an ``else`` in an if-statement, like
+this:
+
+.. code-block:: c
+
+	do {
+		body of do-loop
+	} while (condition);
+
+and
+
+.. code-block:: c
+
+	if (x == y) {
+		..
+	} else if (x > y) {
+		...
+	} else {
+		....
+	}
+
+Rationale: K&R.
+
+Also, note that this brace-placement also minimizes the number of empty
+(or almost empty) lines, without any loss of readability.  Thus, as the
+supply of new-lines on your screen is not a renewable resource (think
+25-line terminal screens here), you have more empty lines to put
+comments on.
+
+Do not unnecessarily use braces where a single statement will do.
+
+.. code-block:: c
+
+	if (condition)
+		action();
+
+and
+
+.. code-block:: none
+
+	if (condition)
+		do_this();
+	else
+		do_that();
+
+This does not apply if only one branch of a conditional statement is a single
+statement; in the latter case use braces in both branches:
+
+.. code-block:: c
+
+	if (condition) {
+		do_this();
+		do_that();
+	} else {
+		otherwise();
+	}
+
+3.1) Spaces
+***********
+
+Linux kernel style for use of spaces depends (mostly) on
+function-versus-keyword usage.  Use a space after (most) keywords.  The
+notable exceptions are sizeof, typeof, alignof, and __attribute__, which look
+somewhat like functions (and are usually used with parentheses in Linux,
+although they are not required in the language, as in: ``sizeof info`` after
+``struct fileinfo info;`` is declared).
+
+So use a space after these keywords::
+
+	if, switch, case, for, do, while
+
+but not with sizeof, typeof, alignof, or __attribute__.  E.g.,
+
+.. code-block:: c
+
+
+	s = sizeof(struct file);
+
+Do not add spaces around (inside) parenthesized expressions.  This example is
+**bad**:
+
+.. code-block:: c
+
+
+	s = sizeof( struct file );
+
+When declaring pointer data or a function that returns a pointer type, the
+preferred use of ``*`` is adjacent to the data name or function name and not
+adjacent to the type name.  Examples:
+
+.. code-block:: c
+
+
+	char *linux_banner;
+	unsigned long long memparse(char *ptr, char **retptr);
+	char *match_strdup(substring_t *s);
+
+Use one space around (on each side of) most binary and ternary operators,
+such as any of these::
+
+	=  +  -  <  >  *  /  %  |  &  ^  <=  >=  ==  !=  ?  :
+
+but no space after unary operators::
+
+	&  *  +  -  ~  !  sizeof  typeof  alignof  __attribute__  defined
+
+no space before the postfix increment & decrement unary operators::
+
+	++  --
+
+no space after the prefix increment & decrement unary operators::
+
+	++  --
+
+and no space around the ``.`` and ``->`` structure member operators.
+
+Do not leave trailing whitespace at the ends of lines.  Some editors with
+``smart`` indentation will insert whitespace at the beginning of new lines as
+appropriate, so you can start typing the next line of code right away.
+However, some such editors do not remove the whitespace if you end up not
+putting a line of code there, such as if you leave a blank line.  As a result,
+you end up with lines containing trailing whitespace.
+
+Git will warn you about patches that introduce trailing whitespace, and can
+optionally strip the trailing whitespace for you; however, if applying a series
+of patches, this may make later patches in the series fail by changing their
+context lines.
+
+
+4) Naming
+---------
+
+C is a Spartan language, and so should your naming be.  Unlike Modula-2
+and Pascal programmers, C programmers do not use cute names like
+ThisVariableIsATemporaryCounter.  A C programmer would call that
+variable ``tmp``, which is much easier to write, and not the least more
+difficult to understand.
+
+HOWEVER, while mixed-case names are frowned upon, descriptive names for
+global variables are a must.  To call a global function ``foo`` is a
+shooting offense.
+
+GLOBAL variables (to be used only if you **really** need them) need to
+have descriptive names, as do global functions.  If you have a function
+that counts the number of active users, you should call that
+``count_active_users()`` or similar, you should **not** call it ``cntusr()``.
+
+Encoding the type of a function into the name (so-called Hungarian
+notation) is brain damaged - the compiler knows the types anyway and can
+check those, and it only confuses the programmer.  No wonder MicroSoft
+makes buggy programs.
+
+LOCAL variable names should be short, and to the point.  If you have
+some random integer loop counter, it should probably be called ``i``.
+Calling it ``loop_counter`` is non-productive, if there is no chance of it
+being mis-understood.  Similarly, ``tmp`` can be just about any type of
+variable that is used to hold a temporary value.
+
+If you are afraid to mix up your local variable names, you have another
+problem, which is called the function-growth-hormone-imbalance syndrome.
+See chapter 6 (Functions).
+
+
+5) Typedefs
+-----------
+
+Please don't use things like ``vps_t``.
+It's a **mistake** to use typedef for structures and pointers. When you see a
+
+.. code-block:: c
+
+
+	vps_t a;
+
+in the source, what does it mean?
+In contrast, if it says
+
+.. code-block:: c
+
+	struct virtual_container *a;
+
+you can actually tell what ``a`` is.
+
+Lots of people think that typedefs ``help readability``. Not so. They are
+useful only for:
+
+ (a) totally opaque objects (where the typedef is actively used to **hide**
+     what the object is).
+
+     Example: ``pte_t`` etc. opaque objects that you can only access using
+     the proper accessor functions.
+
+     .. note::
+
+       Opaqueness and ``accessor functions`` are not good in themselves.
+       The reason we have them for things like pte_t etc. is that there
+       really is absolutely **zero** portably accessible information there.
+
+ (b) Clear integer types, where the abstraction **helps** avoid confusion
+     whether it is ``int`` or ``long``.
+
+     u8/u16/u32 are perfectly fine typedefs, although they fit into
+     category (d) better than here.
+
+     .. note::
+
+       Again - there needs to be a **reason** for this. If something is
+       ``unsigned long``, then there's no reason to do
+
+	typedef unsigned long myflags_t;
+
+     but if there is a clear reason for why it under certain circumstances
+     might be an ``unsigned int`` and under other configurations might be
+     ``unsigned long``, then by all means go ahead and use a typedef.
+
+ (c) when you use sparse to literally create a **new** type for
+     type-checking.
+
+ (d) New types which are identical to standard C99 types, in certain
+     exceptional circumstances.
+
+     Although it would only take a short amount of time for the eyes and
+     brain to become accustomed to the standard types like ``uint32_t``,
+     some people object to their use anyway.
+
+     Therefore, the Linux-specific ``u8/u16/u32/u64`` types and their
+     signed equivalents which are identical to standard types are
+     permitted -- although they are not mandatory in new code of your
+     own.
+
+     When editing existing code which already uses one or the other set
+     of types, you should conform to the existing choices in that code.
+
+ (e) Types safe for use in userspace.
+
+     In certain structures which are visible to userspace, we cannot
+     require C99 types and cannot use the ``u32`` form above. Thus, we
+     use __u32 and similar types in all structures which are shared
+     with userspace.
+
+Maybe there are other cases too, but the rule should basically be to NEVER
+EVER use a typedef unless you can clearly match one of those rules.
+
+In general, a pointer, or a struct that has elements that can reasonably
+be directly accessed should **never** be a typedef.
+
+
+6) Functions
+------------
+
+Functions should be short and sweet, and do just one thing.  They should
+fit on one or two screenfuls of text (the ISO/ANSI screen size is 80x24,
+as we all know), and do one thing and do that well.
+
+The maximum length of a function is inversely proportional to the
+complexity and indentation level of that function.  So, if you have a
+conceptually simple function that is just one long (but simple)
+case-statement, where you have to do lots of small things for a lot of
+different cases, it's OK to have a longer function.
+
+However, if you have a complex function, and you suspect that a
+less-than-gifted first-year high-school student might not even
+understand what the function is all about, you should adhere to the
+maximum limits all the more closely.  Use helper functions with
+descriptive names (you can ask the compiler to in-line them if you think
+it's performance-critical, and it will probably do a better job of it
+than you would have done).
+
+Another measure of the function is the number of local variables.  They
+shouldn't exceed 5-10, or you're doing something wrong.  Re-think the
+function, and split it into smaller pieces.  A human brain can
+generally easily keep track of about 7 different things, anything more
+and it gets confused.  You know you're brilliant, but maybe you'd like
+to understand what you did 2 weeks from now.
+
+In source files, separate functions with one blank line.  If the function is
+exported, the **EXPORT** macro for it should follow immediately after the
+closing function brace line.  E.g.:
+
+.. code-block:: c
+
+	int system_is_up(void)
+	{
+		return system_state == SYSTEM_RUNNING;
+	}
+	EXPORT_SYMBOL(system_is_up);
+
+In function prototypes, include parameter names with their data types.
+Although this is not required by the C language, it is preferred in Linux
+because it is a simple way to add valuable information for the reader.
+
+
+7) Centralized exiting of functions
+-----------------------------------
+
+Albeit deprecated by some people, the equivalent of the goto statement is
+used frequently by compilers in form of the unconditional jump instruction.
+
+The goto statement comes in handy when a function exits from multiple
+locations and some common work such as cleanup has to be done.  If there is no
+cleanup needed then just return directly.
+
+Choose label names which say what the goto does or why the goto exists.  An
+example of a good name could be ``out_free_buffer:`` if the goto frees ``buffer``.
+Avoid using GW-BASIC names like ``err1:`` and ``err2:``, as you would have to
+renumber them if you ever add or remove exit paths, and they make correctness
+difficult to verify anyway.
+
+The rationale for using gotos is:
+
+- unconditional statements are easier to understand and follow
+- nesting is reduced
+- errors by not updating individual exit points when making
+  modifications are prevented
+- saves the compiler work to optimize redundant code away ;)
+
+.. code-block:: c
+
+	int fun(int a)
+	{
+		int result = 0;
+		char *buffer;
+
+		buffer = kmalloc(SIZE, GFP_KERNEL);
+		if (!buffer)
+			return -ENOMEM;
+
+		if (condition1) {
+			while (loop1) {
+				...
+			}
+			result = 1;
+			goto out_free_buffer;
+		}
+		...
+	out_free_buffer:
+		kfree(buffer);
+		return result;
+	}
+
+A common type of bug to be aware of is ``one err bugs`` which look like this:
+
+.. code-block:: c
+
+	err:
+		kfree(foo->bar);
+		kfree(foo);
+		return ret;
+
+The bug in this code is that on some exit paths ``foo`` is NULL.  Normally the
+fix for this is to split it up into two error labels ``err_free_bar:`` and
+``err_free_foo:``:
+
+.. code-block:: c
+
+	 err_free_bar:
+		kfree(foo->bar);
+	 err_free_foo:
+		kfree(foo);
+		return ret;
+
+Ideally you should simulate errors to test all exit paths.
+
+
+8) Commenting
+-------------
+
+Comments are good, but there is also a danger of over-commenting.  NEVER
+try to explain HOW your code works in a comment: it's much better to
+write the code so that the **working** is obvious, and it's a waste of
+time to explain badly written code.
+
+Generally, you want your comments to tell WHAT your code does, not HOW.
+Also, try to avoid putting comments inside a function body: if the
+function is so complex that you need to separately comment parts of it,
+you should probably go back to chapter 6 for a while.  You can make
+small comments to note or warn about something particularly clever (or
+ugly), but try to avoid excess.  Instead, put the comments at the head
+of the function, telling people what it does, and possibly WHY it does
+it.
+
+When commenting the kernel API functions, please use the kernel-doc format.
+See the files at :ref:`Documentation/doc-guide/ <doc_guide>` and
+``scripts/kernel-doc`` for details.
+
+The preferred style for long (multi-line) comments is:
+
+.. code-block:: c
+
+	/*
+	 * This is the preferred style for multi-line
+	 * comments in the Linux kernel source code.
+	 * Please use it consistently.
+	 *
+	 * Description:  A column of asterisks on the left side,
+	 * with beginning and ending almost-blank lines.
+	 */
+
+For files in net/ and drivers/net/ the preferred style for long (multi-line)
+comments is a little different.
+
+.. code-block:: c
+
+	/* The preferred comment style for files in net/ and drivers/net
+	 * looks like this.
+	 *
+	 * It is nearly the same as the generally preferred comment style,
+	 * but there is no initial almost-blank line.
+	 */
+
+It's also important to comment data, whether they are basic types or derived
+types.  To this end, use just one data declaration per line (no commas for
+multiple data declarations).  This leaves you room for a small comment on each
+item, explaining its use.
+
+
+9) You've made a mess of it
+---------------------------
+
+That's OK, we all do.  You've probably been told by your long-time Unix
+user helper that ``GNU emacs`` automatically formats the C sources for
+you, and you've noticed that yes, it does do that, but the defaults it
+uses are less than desirable (in fact, they are worse than random
+typing - an infinite number of monkeys typing into GNU emacs would never
+make a good program).
+
+So, you can either get rid of GNU emacs, or change it to use saner
+values.  To do the latter, you can stick the following in your .emacs file:
+
+.. code-block:: none
+
+  (defun c-lineup-arglist-tabs-only (ignored)
+    "Line up argument lists by tabs, not spaces"
+    (let* ((anchor (c-langelem-pos c-syntactic-element))
+           (column (c-langelem-2nd-pos c-syntactic-element))
+           (offset (- (1+ column) anchor))
+           (steps (floor offset c-basic-offset)))
+      (* (max steps 1)
+         c-basic-offset)))
+
+  (add-hook 'c-mode-common-hook
+            (lambda ()
+              ;; Add kernel style
+              (c-add-style
+               "linux-tabs-only"
+               '("linux" (c-offsets-alist
+                          (arglist-cont-nonempty
+                           c-lineup-gcc-asm-reg
+                           c-lineup-arglist-tabs-only))))))
+
+  (add-hook 'c-mode-hook
+            (lambda ()
+              (let ((filename (buffer-file-name)))
+                ;; Enable kernel mode for the appropriate files
+                (when (and filename
+                           (string-match (expand-file-name "~/src/linux-trees")
+                                         filename))
+                  (setq indent-tabs-mode t)
+                  (setq show-trailing-whitespace t)
+                  (c-set-style "linux-tabs-only")))))
+
+This will make emacs go better with the kernel coding style for C
+files below ``~/src/linux-trees``.
+
+But even if you fail in getting emacs to do sane formatting, not
+everything is lost: use ``indent``.
+
+Now, again, GNU indent has the same brain-dead settings that GNU emacs
+has, which is why you need to give it a few command line options.
+However, that's not too bad, because even the makers of GNU indent
+recognize the authority of K&R (the GNU people aren't evil, they are
+just severely misguided in this matter), so you just give indent the
+options ``-kr -i8`` (stands for ``K&R, 8 character indents``), or use
+``scripts/Lindent``, which indents in the latest style.
+
+``indent`` has a lot of options, and especially when it comes to comment
+re-formatting you may want to take a look at the man page.  But
+remember: ``indent`` is not a fix for bad programming.
+
+
+10) Kconfig configuration files
+-------------------------------
+
+For all of the Kconfig* configuration files throughout the source tree,
+the indentation is somewhat different.  Lines under a ``config`` definition
+are indented with one tab, while help text is indented an additional two
+spaces.  Example::
+
+  config AUDIT
+	bool "Auditing support"
+	depends on NET
+	help
+	  Enable auditing infrastructure that can be used with another
+	  kernel subsystem, such as SELinux (which requires this for
+	  logging of avc messages output).  Does not do system-call
+	  auditing without CONFIG_AUDITSYSCALL.
+
+Seriously dangerous features (such as write support for certain
+filesystems) should advertise this prominently in their prompt string::
+
+  config ADFS_FS_RW
+	bool "ADFS write support (DANGEROUS)"
+	depends on ADFS_FS
+	...
+
+For full documentation on the configuration files, see the file
+Documentation/kbuild/kconfig-language.txt.
+
+
+11) Data structures
+-------------------
+
+Data structures that have visibility outside the single-threaded
+environment they are created and destroyed in should always have
+reference counts.  In the kernel, garbage collection doesn't exist (and
+outside the kernel garbage collection is slow and inefficient), which
+means that you absolutely **have** to reference count all your uses.
+
+Reference counting means that you can avoid locking, and allows multiple
+users to have access to the data structure in parallel - and not having
+to worry about the structure suddenly going away from under them just
+because they slept or did something else for a while.
+
+Note that locking is **not** a replacement for reference counting.
+Locking is used to keep data structures coherent, while reference
+counting is a memory management technique.  Usually both are needed, and
+they are not to be confused with each other.
+
+Many data structures can indeed have two levels of reference counting,
+when there are users of different ``classes``.  The subclass count counts
+the number of subclass users, and decrements the global count just once
+when the subclass count goes to zero.
+
+Examples of this kind of ``multi-level-reference-counting`` can be found in
+memory management (``struct mm_struct``: mm_users and mm_count), and in
+filesystem code (``struct super_block``: s_count and s_active).
+
+Remember: if another thread can find your data structure, and you don't
+have a reference count on it, you almost certainly have a bug.
+
+
+12) Macros, Enums and RTL
+-------------------------
+
+Names of macros defining constants and labels in enums are capitalized.
+
+.. code-block:: c
+
+	#define CONSTANT 0x12345
+
+Enums are preferred when defining several related constants.
+
+CAPITALIZED macro names are appreciated but macros resembling functions
+may be named in lower case.
+
+Generally, inline functions are preferable to macros resembling functions.
+
+Macros with multiple statements should be enclosed in a do - while block:
+
+.. code-block:: c
+
+	#define macrofun(a, b, c)			\
+		do {					\
+			if (a == 5)			\
+				do_this(b, c);		\
+		} while (0)
+
+Things to avoid when using macros:
+
+1) macros that affect control flow:
+
+.. code-block:: c
+
+	#define FOO(x)					\
+		do {					\
+			if (blah(x) < 0)		\
+				return -EBUGGERED;	\
+		} while (0)
+
+is a **very** bad idea.  It looks like a function call but exits the ``calling``
+function; don't break the internal parsers of those who will read the code.
+
+2) macros that depend on having a local variable with a magic name:
+
+.. code-block:: c
+
+	#define FOO(val) bar(index, val)
+
+might look like a good thing, but it's confusing as hell when one reads the
+code and it's prone to breakage from seemingly innocent changes.
+
+3) macros with arguments that are used as l-values: FOO(x) = y; will
+bite you if somebody e.g. turns FOO into an inline function.
+
+4) forgetting about precedence: macros defining constants using expressions
+must enclose the expression in parentheses. Beware of similar issues with
+macros using parameters.
+
+.. code-block:: c
+
+	#define CONSTANT 0x4000
+	#define CONSTEXP (CONSTANT | 3)
+
+5) namespace collisions when defining local variables in macros resembling
+functions:
+
+.. code-block:: c
+
+	#define FOO(x)				\
+	({					\
+		typeof(x) ret;			\
+		ret = calc_ret(x);		\
+		(ret);				\
+	})
+
+ret is a common name for a local variable - __foo_ret is less likely
+to collide with an existing variable.
+
+The cpp manual deals with macros exhaustively. The gcc internals manual also
+covers RTL which is used frequently with assembly language in the kernel.
+
+
+13) Printing kernel messages
+----------------------------
+
+Kernel developers like to be seen as literate. Do mind the spelling
+of kernel messages to make a good impression. Do not use crippled
+words like ``dont``; use ``do not`` or ``don't`` instead.  Make the messages
+concise, clear, and unambiguous.
+
+Kernel messages do not have to be terminated with a period.
+
+Printing numbers in parentheses (%d) adds no value and should be avoided.
+
+There are a number of driver model diagnostic macros in <linux/device.h>
+which you should use to make sure messages are matched to the right device
+and driver, and are tagged with the right level:  dev_err(), dev_warn(),
+dev_info(), and so forth.  For messages that aren't associated with a
+particular device, <linux/printk.h> defines pr_notice(), pr_info(),
+pr_warn(), pr_err(), etc.
+
+Coming up with good debugging messages can be quite a challenge; and once
+you have them, they can be a huge help for remote troubleshooting.  However
+debug message printing is handled differently than printing other non-debug
+messages.  While the other pr_XXX() functions print unconditionally,
+pr_debug() does not; it is compiled out by default, unless either DEBUG is
+defined or CONFIG_DYNAMIC_DEBUG is set.  That is true for dev_dbg() also,
+and a related convention uses VERBOSE_DEBUG to add dev_vdbg() messages to
+the ones already enabled by DEBUG.
+
+Many subsystems have Kconfig debug options to turn on -DDEBUG in the
+corresponding Makefile; in other cases specific files #define DEBUG.  And
+when a debug message should be unconditionally printed, such as if it is
+already inside a debug-related #ifdef section, printk(KERN_DEBUG ...) can be
+used.
+
+
+14) Allocating memory
+---------------------
+
+The kernel provides the following general purpose memory allocators:
+kmalloc(), kzalloc(), kmalloc_array(), kcalloc(), vmalloc(), and
+vzalloc().  Please refer to the API documentation for further information
+about them.
+
+The preferred form for passing a size of a struct is the following:
+
+.. code-block:: c
+
+	p = kmalloc(sizeof(*p), ...);
+
+The alternative form where struct name is spelled out hurts readability and
+introduces an opportunity for a bug when the pointer variable type is changed
+but the corresponding sizeof that is passed to a memory allocator is not.
+
+Casting the return value which is a void pointer is redundant. The conversion
+from void pointer to any other pointer type is guaranteed by the C programming
+language.
+
+The preferred form for allocating an array is the following:
+
+.. code-block:: c
+
+	p = kmalloc_array(n, sizeof(...), ...);
+
+The preferred form for allocating a zeroed array is the following:
+
+.. code-block:: c
+
+	p = kcalloc(n, sizeof(...), ...);
+
+Both forms check for overflow on the allocation size n * sizeof(...),
+and return NULL if that occurred.
+
+
+15) The inline disease
+----------------------
+
+There appears to be a common misperception that gcc has a magic "make me
+faster" speedup option called ``inline``. While the use of inlines can be
+appropriate (for example as a means of replacing macros, see Chapter 12), it
+very often is not. Abundant use of the inline keyword leads to a much bigger
+kernel, which in turn slows the system as a whole down, due to a bigger
+icache footprint for the CPU and simply because there is less memory
+available for the pagecache. Just think about it; a pagecache miss causes a
+disk seek, which easily takes 5 milliseconds. There are a LOT of cpu cycles
+that can go into these 5 milliseconds.
+
+A reasonable rule of thumb is to not put inline at functions that have more
+than 3 lines of code in them. An exception to this rule are the cases where
+a parameter is known to be a compiletime constant, and as a result of this
+constantness you *know* the compiler will be able to optimize most of your
+function away at compile time. For a good example of this later case, see
+the kmalloc() inline function.
+
+Often people argue that adding inline to functions that are static and used
+only once is always a win since there is no space tradeoff. While this is
+technically correct, gcc is capable of inlining these automatically without
+help, and the maintenance issue of removing the inline when a second user
+appears outweighs the potential value of the hint that tells gcc to do
+something it would have done anyway.
+
+
+16) Function return values and names
+------------------------------------
+
+Functions can return values of many different kinds, and one of the
+most common is a value indicating whether the function succeeded or
+failed.  Such a value can be represented as an error-code integer
+(-Exxx = failure, 0 = success) or a ``succeeded`` boolean (0 = failure,
+non-zero = success).
+
+Mixing up these two sorts of representations is a fertile source of
+difficult-to-find bugs.  If the C language included a strong distinction
+between integers and booleans then the compiler would find these mistakes
+for us... but it doesn't.  To help prevent such bugs, always follow this
+convention::
+
+	If the name of a function is an action or an imperative command,
+	the function should return an error-code integer.  If the name
+	is a predicate, the function should return a "succeeded" boolean.
+
+For example, ``add work`` is a command, and the add_work() function returns 0
+for success or -EBUSY for failure.  In the same way, ``PCI device present`` is
+a predicate, and the pci_dev_present() function returns 1 if it succeeds in
+finding a matching device or 0 if it doesn't.
+
+All EXPORTed functions must respect this convention, and so should all
+public functions.  Private (static) functions need not, but it is
+recommended that they do.
+
+Functions whose return value is the actual result of a computation, rather
+than an indication of whether the computation succeeded, are not subject to
+this rule.  Generally they indicate failure by returning some out-of-range
+result.  Typical examples would be functions that return pointers; they use
+NULL or the ERR_PTR mechanism to report failure.
+
+
+17) Don't re-invent the kernel macros
+-------------------------------------
+
+The header file include/linux/kernel.h contains a number of macros that
+you should use, rather than explicitly coding some variant of them yourself.
+For example, if you need to calculate the length of an array, take advantage
+of the macro
+
+.. code-block:: c
+
+	#define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0]))
+
+Similarly, if you need to calculate the size of some structure member, use
+
+.. code-block:: c
+
+	#define FIELD_SIZEOF(t, f) (sizeof(((t*)0)->f))
+
+There are also min() and max() macros that do strict type checking if you
+need them.  Feel free to peruse that header file to see what else is already
+defined that you shouldn't reproduce in your code.
+
+
+18) Editor modelines and other cruft
+------------------------------------
+
+Some editors can interpret configuration information embedded in source files,
+indicated with special markers.  For example, emacs interprets lines marked
+like this:
+
+.. code-block:: c
+
+	-*- mode: c -*-
+
+Or like this:
+
+.. code-block:: c
+
+	/*
+	Local Variables:
+	compile-command: "gcc -DMAGIC_DEBUG_FLAG foo.c"
+	End:
+	*/
+
+Vim interprets markers that look like this:
+
+.. code-block:: c
+
+	/* vim:set sw=8 noet */
+
+Do not include any of these in source files.  People have their own personal
+editor configurations, and your source files should not override them.  This
+includes markers for indentation and mode configuration.  People may use their
+own custom mode, or may have some other magic method for making indentation
+work correctly.
+
+
+19) Inline assembly
+-------------------
+
+In architecture-specific code, you may need to use inline assembly to interface
+with CPU or platform functionality.  Don't hesitate to do so when necessary.
+However, don't use inline assembly gratuitously when C can do the job.  You can
+and should poke hardware from C when possible.
+
+Consider writing simple helper functions that wrap common bits of inline
+assembly, rather than repeatedly writing them with slight variations.  Remember
+that inline assembly can use C parameters.
+
+Large, non-trivial assembly functions should go in .S files, with corresponding
+C prototypes defined in C header files.  The C prototypes for assembly
+functions should use ``asmlinkage``.
+
+You may need to mark your asm statement as volatile, to prevent GCC from
+removing it if GCC doesn't notice any side effects.  You don't always need to
+do so, though, and doing so unnecessarily can limit optimization.
+
+When writing a single inline assembly statement containing multiple
+instructions, put each instruction on a separate line in a separate quoted
+string, and end each string except the last with \n\t to properly indent the
+next instruction in the assembly output:
+
+.. code-block:: c
+

+
+20) Conditional Compilation
+---------------------------
+
+Wherever possible, don't use preprocessor conditionals (#if, #ifdef) in .c
+files; doing so makes code harder to read and logic harder to follow.  Instead,
+use such conditionals in a header file defining functions for use in those .c
+files, providing no-op stub versions in the #else case, and then call those
+functions unconditionally from .c files.  The compiler will avoid generating
+any code for the stub calls, producing identical results, but the logic will
+remain easy to follow.
+
+Prefer to compile out entire functions, rather than portions of functions or
+portions of expressions.  Rather than putting an ifdef in an expression, factor
+out part or all of the expression into a separate helper function and apply the
+conditional to that function.
+
+If you have a function or variable which may potentially go unused in a
+particular configuration, and the compiler would warn about its definition
+going unused, mark the definition as __maybe_unused rather than wrapping it in
+a preprocessor conditional.  (However, if a function or variable *always* goes
+unused, delete it.)
+
+Within code, where possible, use the IS_ENABLED macro to convert a Kconfig
+symbol into a C boolean expression, and use it in a normal C conditional:
+
+.. code-block:: c
+
+	if (IS_ENABLED(CONFIG_SOMETHING)) {
+		...
+	}
+
+The compiler will constant-fold the conditional away, and include or exclude
+the block of code just as with an #ifdef, so this will not add any runtime
+overhead.  However, this approach still allows the C compiler to see the code
+inside the block, and check it for correctness (syntax, types, symbol
+references, etc).  Thus, you still have to use an #ifdef if the code inside the
+block references symbols that will not exist if the condition is not met.
+
+At the end of any non-trivial #if or #ifdef block (more than a few lines),
+place a comment after the #endif on the same line, noting the conditional
+expression used.  For instance:
+
+.. code-block:: c
+
+	#ifdef CONFIG_SOMETHING
+	...
+	#endif /* CONFIG_SOMETHING */

+Linux magic numbers
+===================
+
+This file is a registry of magic numbers which are in use.  When you
+add a magic number to a structure, you should also add it to this
+file, since it is best if the magic numbers used by various structures
+are unique.
+
+It is a **very** good idea to protect kernel data structures with magic
+numbers.  This allows you to check at run time whether (a) a structure
+has been clobbered, or (b) you've passed the wrong structure to a
+routine.  This last is especially useful --- particularly when you are
+passing pointers to structures via a void * pointer.  The tty code,
+for example, does this frequently to pass driver-specific and line
+discipline-specific structures back and forth.
+
+The way to use magic numbers is to declare then at the beginning of
+the structure, like so::
+
+	struct tty_ldisc {
+		int	magic;
+		...
+	};
+
+Please follow this discipline when you are adding future enhancements
+to the kernel!  It has saved me countless hours of debugging,
+especially in the screwy cases where an array has been overrun and
+structures following the array have been overwritten.  Using this
+discipline, these cases get detected quickly and safely.

+Submitting patches: the essential guide to getting your code into the kernel
+============================================================================
+
+For a person or company who wishes to submit a change to the Linux
+kernel, the process can sometimes be daunting if you're not familiar
+with "the system."  This text is a collection of suggestions which
+can greatly increase the chances of your change being accepted.
+
+This document contains a large number of suggestions in a relatively terse
+format.  For detailed information on how the kernel development process
+works, see :ref:`Documentation/process <development_process_main>`.
+Also, read :ref:`Documentation/process/submit-checklist.rst <submitchecklist>`
+for a list of items to check before
+submitting code.  If you are submitting a driver, also read
+:ref:`Documentation/process/submitting-drivers.rst <submittingdrivers>`;
+for device tree binding patches, read
+Documentation/devicetree/bindings/submitting-patches.txt.
+
+Many of these steps describe the default behavior of the ``git`` version
+control system; if you use ``git`` to prepare your patches, you'll find much
+of the mechanical work done for you, though you'll still need to prepare
+and document a sensible set of patches.  In general, use of ``git`` will make
+your life as a kernel developer easier.
+
+0) Obtain a current source tree
+-------------------------------
+
+If you do not have a repository with the current kernel source handy, use
+``git`` to obtain one.  You'll want to start with the mainline repository,
+which can be grabbed with::
+
+  git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
+
+Note, however, that you may not want to develop against the mainline tree
+directly.  Most subsystem maintainers run their own trees and want to see
+patches prepared against those trees.  See the **T:** entry for the subsystem
+in the MAINTAINERS file to find that tree, or simply ask the maintainer if
+the tree is not listed there.
+
+It is still possible to download kernel releases via tarballs (as described
+in the next section), but that is the hard way to do kernel development.
+
+1) ``diff -up``
+---------------
+
+If you must generate your patches by hand, use ``diff -up`` or ``diff -uprN``
+to create patches.  Git generates patches in this form by default; if
+you're using ``git``, you can skip this section entirely.
+
+All changes to the Linux kernel occur in the form of patches, as
+generated by :manpage:`diff(1)`.  When creating your patch, make sure to
+create it in "unified diff" format, as supplied by the ``-u`` argument
+to :manpage:`diff(1)`.
+Also, please use the ``-p`` argument which shows which C function each
+change is in - that makes the resultant ``diff`` a lot easier to read.
+Patches should be based in the root kernel source directory,
+not in any lower subdirectory.
+
+To create a patch for a single file, it is often sufficient to do::
+
+	SRCTREE= linux
+	MYFILE=  drivers/net/mydriver.c
+
+	cd $SRCTREE
+	cp $MYFILE $MYFILE.orig
+	vi $MYFILE	# make your change
+	cd ..
+	diff -up $SRCTREE/$MYFILE{.orig,} > /tmp/patch
+
+To create a patch for multiple files, you should unpack a "vanilla",
+or unmodified kernel source tree, and generate a ``diff`` against your
+own source tree.  For example::
+
+	MYSRC= /devel/linux
+
+	tar xvfz linux-3.19.tar.gz
+	mv linux-3.19 linux-3.19-vanilla
+	diff -uprN -X linux-3.19-vanilla/Documentation/dontdiff \
+		linux-3.19-vanilla $MYSRC > /tmp/patch
+
+``dontdiff`` is a list of files which are generated by the kernel during
+the build process, and should be ignored in any :manpage:`diff(1)`-generated
+patch.
+
+Make sure your patch does not include any extra files which do not
+belong in a patch submission.  Make sure to review your patch -after-
+generating it with :manpage:`diff(1)`, to ensure accuracy.
+
+If your changes produce a lot of deltas, you need to split them into
+individual patches which modify things in logical stages; see
+:ref:`split_changes`.  This will facilitate review by other kernel developers,
+very important if you want your patch accepted.
+
+If you're using ``git``, ``git rebase -i`` can help you with this process.  If
+you're not using ``git``, ``quilt`` <http://savannah.nongnu.org/projects/quilt>
+is another popular alternative.
+
+.. _describe_changes:
+
+2) Describe your changes
+------------------------
+
+Describe your problem.  Whether your patch is a one-line bug fix or
+5000 lines of a new feature, there must be an underlying problem that
+motivated you to do this work.  Convince the reviewer that there is a
+problem worth fixing and that it makes sense for them to read past the
+first paragraph.
+
+Describe user-visible impact.  Straight up crashes and lockups are
+pretty convincing, but not all bugs are that blatant.  Even if the
+problem was spotted during code review, describe the impact you think
+it can have on users.  Keep in mind that the majority of Linux
+installations run kernels from secondary stable trees or
+vendor/product-specific trees that cherry-pick only specific patches
+from upstream, so include anything that could help route your change
+downstream: provoking circumstances, excerpts from dmesg, crash
+descriptions, performance regressions, latency spikes, lockups, etc.
+
+Quantify optimizations and trade-offs.  If you claim improvements in
+performance, memory consumption, stack footprint, or binary size,
+include numbers that back them up.  But also describe non-obvious
+costs.  Optimizations usually aren't free but trade-offs between CPU,
+memory, and readability; or, when it comes to heuristics, between
+different workloads.  Describe the expected downsides of your
+optimization so that the reviewer can weigh costs against benefits.
+
+Once the problem is established, describe what you are actually doing
+about it in technical detail.  It's important to describe the change
+in plain English for the reviewer to verify that the code is behaving
+as you intend it to.
+
+The maintainer will thank you if you write your patch description in a
+form which can be easily pulled into Linux's source code management
+system, ``git``, as a "commit log".  See :ref:`explicit_in_reply_to`.
+
+Solve only one problem per patch.  If your description starts to get
+long, that's a sign that you probably need to split up your patch.
+See :ref:`split_changes`.
+
+When you submit or resubmit a patch or patch series, include the
+complete patch description and justification for it.  Don't just
+say that this is version N of the patch (series).  Don't expect the
+subsystem maintainer to refer back to earlier patch versions or referenced
+URLs to find the patch description and put that into the patch.
+I.e., the patch (series) and its description should be self-contained.
+This benefits both the maintainers and reviewers.  Some reviewers
+probably didn't even receive earlier versions of the patch.
+
+Describe your changes in imperative mood, e.g. "make xyzzy do frotz"
+instead of "[This patch] makes xyzzy do frotz" or "[I] changed xyzzy
+to do frotz", as if you are giving orders to the codebase to change
+its behaviour.
+
+If the patch fixes a logged bug entry, refer to that bug entry by
+number and URL.  If the patch follows from a mailing list discussion,
+give a URL to the mailing list archive; use the https://lkml.kernel.org/
+redirector with a ``Message-Id``, to ensure that the links cannot become
+stale.
+
+However, try to make your explanation understandable without external
+resources.  In addition to giving a URL to a mailing list archive or
+bug, summarize the relevant points of the discussion that led to the
+patch as submitted.
+
+If you want to refer to a specific commit, don't just refer to the
+SHA-1 ID of the commit. Please also include the oneline summary of
+the commit, to make it easier for reviewers to know what it is about.
+Example::
+
+	Commit e21d2170f36602ae2708 ("video: remove unnecessary
+	platform_set_drvdata()") removed the unnecessary
+	platform_set_drvdata(), but left the variable "dev" unused,
+	delete it.
+
+You should also be sure to use at least the first twelve characters of the
+SHA-1 ID.  The kernel repository holds a *lot* of objects, making
+collisions with shorter IDs a real possibility.  Bear in mind that, even if
+there is no collision with your six-character ID now, that condition may
+change five years from now.
+
+If your patch fixes a bug in a specific commit, e.g. you found an issue using
+``git bisect``, please use the 'Fixes:' tag with the first 12 characters of
+the SHA-1 ID, and the one line summary.  For example::
+
+	Fixes: e21d2170f366 ("video: remove unnecessary platform_set_drvdata()")
+
+The following ``git config`` settings can be used to add a pretty format for
+outputting the above style in the ``git log`` or ``git show`` commands::
+
+	[core]
+		abbrev = 12
+	[pretty]
+		fixes = Fixes: %h (\"%s\")
+
+.. _split_changes:
+
+3) Separate your changes
+------------------------
+
+Separate each **logical change** into a separate patch.
+
+For example, if your changes include both bug fixes and performance
+enhancements for a single driver, separate those changes into two
+or more patches.  If your changes include an API update, and a new
+driver which uses that new API, separate those into two patches.
+
+On the other hand, if you make a single change to numerous files,
+group those changes into a single patch.  Thus a single logical change
+is contained within a single patch.
+
+The point to remember is that each patch should make an easily understood
+change that can be verified by reviewers.  Each patch should be justifiable
+on its own merits.
+
+If one patch depends on another patch in order for a change to be
+complete, that is OK.  Simply note **"this patch depends on patch X"**
+in your patch description.
+
+When dividing your change into a series of patches, take special care to
+ensure that the kernel builds and runs properly after each patch in the
+series.  Developers using ``git bisect`` to track down a problem can end up
+splitting your patch series at any point; they will not thank you if you
+introduce bugs in the middle.
+
+If you cannot condense your patch set into a smaller set of patches,
+then only post say 15 or so at a time and wait for review and integration.
+
+
+
+4) Style-check your changes
+---------------------------
+
+Check your patch for basic style violations, details of which can be
+found in
+:ref:`Documentation/process/coding-style.rst <codingstyle>`.
+Failure to do so simply wastes
+the reviewers time and will get your patch rejected, probably
+without even being read.
+
+One significant exception is when moving code from one file to
+another -- in this case you should not modify the moved code at all in
+the same patch which moves it.  This clearly delineates the act of
+moving the code and your changes.  This greatly aids review of the
+actual differences and allows tools to better track the history of
+the code itself.
+
+Check your patches with the patch style checker prior to submission
+(scripts/checkpatch.pl).  Note, though, that the style checker should be
+viewed as a guide, not as a replacement for human judgment.  If your code
+looks better with a violation then its probably best left alone.
+
+The checker reports at three levels:
+ - ERROR: things that are very likely to be wrong
+ - WARNING: things requiring careful review
+ - CHECK: things requiring thought
+
+You should be able to justify all violations that remain in your
+patch.
+
+
+5) Select the recipients for your patch
+---------------------------------------
+
+You should always copy the appropriate subsystem maintainer(s) on any patch
+to code that they maintain; look through the MAINTAINERS file and the
+source code revision history to see who those maintainers are.  The
+script scripts/get_maintainer.pl can be very useful at this step.  If you
+cannot find a maintainer for the subsystem you are working on, Andrew
+Morton (akpm@linux-foundation.org) serves as a maintainer of last resort.
+
+You should also normally choose at least one mailing list to receive a copy
+of your patch set.  linux-kernel@vger.kernel.org functions as a list of
+last resort, but the volume on that list has caused a number of developers
+to tune it out.  Look in the MAINTAINERS file for a subsystem-specific
+list; your patch will probably get more attention there.  Please do not
+spam unrelated lists, though.
+
+Many kernel-related lists are hosted on vger.kernel.org; you can find a
+list of them at http://vger.kernel.org/vger-lists.html.  There are
+kernel-related lists hosted elsewhere as well, though.
+
+Do not send more than 15 patches at once to the vger mailing lists!!!
+
+Linus Torvalds is the final arbiter of all changes accepted into the
+Linux kernel.  His e-mail address is <torvalds@linux-foundation.org>.
+He gets a lot of e-mail, and, at this point, very few patches go through
+Linus directly, so typically you should do your best to -avoid-
+sending him e-mail.
+
+If you have a patch that fixes an exploitable security bug, send that patch
+to security@kernel.org.  For severe bugs, a short embargo may be considered
+to allow distributors to get the patch out to users; in such cases,
+obviously, the patch should not be sent to any public lists.
+
+Patches that fix a severe bug in a released kernel should be directed
+toward the stable maintainers by putting a line like this::
+
+  Cc: stable@vger.kernel.org
+
+into the sign-off area of your patch (note, NOT an email recipient).  You
+should also read
+:ref:`Documentation/process/stable-kernel-rules.rst <stable_kernel_rules>`
+in addition to this file.
+
+Note, however, that some subsystem maintainers want to come to their own
+conclusions on which patches should go to the stable trees.  The networking
+maintainer, in particular, would rather not see individual developers
+adding lines like the above to their patches.
+
+If changes affect userland-kernel interfaces, please send the MAN-PAGES
+maintainer (as listed in the MAINTAINERS file) a man-pages patch, or at
+least a notification of the change, so that some information makes its way
+into the manual pages.  User-space API changes should also be copied to
+linux-api@vger.kernel.org.
+
+For small patches you may want to CC the Trivial Patch Monkey
+trivial@kernel.org which collects "trivial" patches. Have a look
+into the MAINTAINERS file for its current manager.
+
+Trivial patches must qualify for one of the following rules:
+
+- Spelling fixes in documentation
+- Spelling fixes for errors which could break :manpage:`grep(1)`
+- Warning fixes (cluttering with useless warnings is bad)
+- Compilation fixes (only if they are actually correct)
+- Runtime fixes (only if they actually fix things)
+- Removing use of deprecated functions/macros
+- Contact detail and documentation fixes
+- Non-portable code replaced by portable code (even in arch-specific,
+  since people copy, as long as it's trivial)
+- Any fix by the author/maintainer of the file (ie. patch monkey
+  in re-transmission mode)
+
+
+
+6) No MIME, no links, no compression, no attachments.  Just plain text
+----------------------------------------------------------------------
+
+Linus and other kernel developers need to be able to read and comment
+on the changes you are submitting.  It is important for a kernel
+developer to be able to "quote" your changes, using standard e-mail
+tools, so that they may comment on specific portions of your code.
+
+For this reason, all patches should be submitted by e-mail "inline".
+
+.. warning::
+
+  Be wary of your editor's word-wrap corrupting your patch,
+  if you choose to cut-n-paste your patch.
+
+Do not attach the patch as a MIME attachment, compressed or not.
+Many popular e-mail applications will not always transmit a MIME
+attachment as plain text, making it impossible to comment on your
+code.  A MIME attachment also takes Linus a bit more time to process,
+decreasing the likelihood of your MIME-attached change being accepted.
+
+Exception:  If your mailer is mangling patches then someone may ask
+you to re-send them using MIME.
+
+See :ref:`Documentation/process/email-clients.rst <email_clients>`
+for hints about configuring your e-mail client so that it sends your patches
+untouched.
+
+7) E-mail size
+--------------
+
+Large changes are not appropriate for mailing lists, and some
+maintainers.  If your patch, uncompressed, exceeds 300 kB in size,
+it is preferred that you store your patch on an Internet-accessible
+server, and provide instead a URL (link) pointing to your patch.  But note
+that if your patch exceeds 300 kB, it almost certainly needs to be broken up
+anyway.
+
+8) Respond to review comments
+-----------------------------
+
+Your patch will almost certainly get comments from reviewers on ways in
+which the patch can be improved.  You must respond to those comments;
+ignoring reviewers is a good way to get ignored in return.  Review comments
+or questions that do not lead to a code change should almost certainly
+bring about a comment or changelog entry so that the next reviewer better
+understands what is going on.
+
+Be sure to tell the reviewers what changes you are making and to thank them
+for their time.  Code review is a tiring and time-consuming process, and
+reviewers sometimes get grumpy.  Even in that case, though, respond
+politely and address the problems they have pointed out.
+
+
+9) Don't get discouraged - or impatient
+---------------------------------------
+
+After you have submitted your change, be patient and wait.  Reviewers are
+busy people and may not get to your patch right away.
+
+Once upon a time, patches used to disappear into the void without comment,
+but the development process works more smoothly than that now.  You should
+receive comments within a week or so; if that does not happen, make sure
+that you have sent your patches to the right place.  Wait for a minimum of
+one week before resubmitting or pinging reviewers - possibly longer during
+busy times like merge windows.
+
+
+10) Include PATCH in the subject
+--------------------------------
+
+Due to high e-mail traffic to Linus, and to linux-kernel, it is common
+convention to prefix your subject line with [PATCH].  This lets Linus
+and other kernel developers more easily distinguish patches from other
+e-mail discussions.
+
+
+
+11) Sign your work — the Developer's Certificate of Origin
+----------------------------------------------------------
+
+To improve tracking of who did what, especially with patches that can
+percolate to their final resting place in the kernel through several
+layers of maintainers, we've introduced a "sign-off" procedure on
+patches that are being emailed around.
+
+The sign-off is a simple line at the end of the explanation for the
+patch, which certifies that you wrote it or otherwise have the right to
+pass it on as an open-source patch.  The rules are pretty simple: if you
+can certify the below:
+
+Developer's Certificate of Origin 1.1
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By making a contribution to this project, I certify that:
+
+        (a) The contribution was created in whole or in part by me and I
+            have the right to submit it under the open source license
+            indicated in the file; or
+
+        (b) The contribution is based upon previous work that, to the best
+            of my knowledge, is covered under an appropriate open source
+            license and I have the right under that license to submit that
+            work with modifications, whether created in whole or in part
+            by me, under the same open source license (unless I am
+            permitted to submit under a different license), as indicated
+            in the file; or
+
+        (c) The contribution was provided directly to me by some other
+            person who certified (a), (b) or (c) and I have not modified
+            it.
+
+        (d) I understand and agree that this project and the contribution
+            are public and that a record of the contribution (including all
+            personal information I submit with it, including my sign-off) is
+            maintained indefinitely and may be redistributed consistent with
+            this project or the open source license(s) involved.
+
+then you just add a line saying::
+
+	Signed-off-by: Random J Developer <random@developer.example.org>
+
+using your real name (sorry, no pseudonyms or anonymous contributions.)
+
+Some people also put extra tags at the end.  They'll just be ignored for
+now, but you can do this to mark internal company procedures or just
+point out some special detail about the sign-off.
+
+If you are a subsystem or branch maintainer, sometimes you need to slightly
+modify patches you receive in order to merge them, because the code is not
+exactly the same in your tree and the submitters'. If you stick strictly to
+rule (c), you should ask the submitter to rediff, but this is a totally
+counter-productive waste of time and energy. Rule (b) allows you to adjust
+the code, but then it is very impolite to change one submitter's code and
+make him endorse your bugs. To solve this problem, it is recommended that
+you add a line between the last Signed-off-by header and yours, indicating
+the nature of your changes. While there is nothing mandatory about this, it
+seems like prepending the description with your mail and/or name, all
+enclosed in square brackets, is noticeable enough to make it obvious that
+you are responsible for last-minute changes. Example::
+
+	Signed-off-by: Random J Developer <random@developer.example.org>
+	[lucky@maintainer.example.org: struct foo moved from foo.c to foo.h]
+	Signed-off-by: Lucky K Maintainer <lucky@maintainer.example.org>
+
+This practice is particularly helpful if you maintain a stable branch and
+want at the same time to credit the author, track changes, merge the fix,
+and protect the submitter from complaints. Note that under no circumstances
+can you change the author's identity (the From header), as it is the one
+which appears in the changelog.
+
+Special note to back-porters: It seems to be a common and useful practice
+to insert an indication of the origin of a patch at the top of the commit
+message (just after the subject line) to facilitate tracking. For instance,
+here's what we see in a 3.x-stable release::
+
+  Date:   Tue Oct 7 07:26:38 2014 -0400
+
+    libata: Un-break ATA blacklist
+
+    commit 1c40279960bcd7d52dbdf1d466b20d24b99176c8 upstream.
+
+And here's what might appear in an older kernel once a patch is backported::
+
+    Date:   Tue May 13 22:12:27 2008 +0200
+
+        wireless, airo: waitbusy() won't delay
+
+        [backport of 2.6 commit b7acbdfbd1f277c1eb23f344f899cfa4cd0bf36a]
+
+Whatever the format, this information provides a valuable help to people
+tracking your trees, and to people trying to troubleshoot bugs in your
+tree.
+
+
+12) When to use Acked-by: and Cc:
+---------------------------------
+
+The Signed-off-by: tag indicates that the signer was involved in the
+development of the patch, or that he/she was in the patch's delivery path.
+
+If a person was not directly involved in the preparation or handling of a
+patch but wishes to signify and record their approval of it then they can
+ask to have an Acked-by: line added to the patch's changelog.
+
+Acked-by: is often used by the maintainer of the affected code when that
+maintainer neither contributed to nor forwarded the patch.
+
+Acked-by: is not as formal as Signed-off-by:.  It is a record that the acker
+has at least reviewed the patch and has indicated acceptance.  Hence patch
+mergers will sometimes manually convert an acker's "yep, looks good to me"
+into an Acked-by: (but note that it is usually better to ask for an
+explicit ack).
+
+Acked-by: does not necessarily indicate acknowledgement of the entire patch.
+For example, if a patch affects multiple subsystems and has an Acked-by: from
+one subsystem maintainer then this usually indicates acknowledgement of just
+the part which affects that maintainer's code.  Judgement should be used here.
+When in doubt people should refer to the original discussion in the mailing
+list archives.
+
+If a person has had the opportunity to comment on a patch, but has not
+provided such comments, you may optionally add a ``Cc:`` tag to the patch.
+This is the only tag which might be added without an explicit action by the
+person it names - but it should indicate that this person was copied on the
+patch.  This tag documents that potentially interested parties
+have been included in the discussion.
+
+
+13) Using Reported-by:, Tested-by:, Reviewed-by:, Suggested-by: and Fixes:
+--------------------------------------------------------------------------
+
+The Reported-by tag gives credit to people who find bugs and report them and it
+hopefully inspires them to help us again in the future.  Please note that if
+the bug was reported in private, then ask for permission first before using the
+Reported-by tag.
+
+A Tested-by: tag indicates that the patch has been successfully tested (in
+some environment) by the person named.  This tag informs maintainers that
+some testing has been performed, provides a means to locate testers for
+future patches, and ensures credit for the testers.
+
+Reviewed-by:, instead, indicates that the patch has been reviewed and found
+acceptable according to the Reviewer's Statement:
+
+Reviewer's statement of oversight
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By offering my Reviewed-by: tag, I state that:
+
+	 (a) I have carried out a technical review of this patch to
+	     evaluate its appropriateness and readiness for inclusion into
+	     the mainline kernel.
+
+	 (b) Any problems, concerns, or questions relating to the patch
+	     have been communicated back to the submitter.  I am satisfied
+	     with the submitter's response to my comments.
+
+	 (c) While there may be things that could be improved with this
+	     submission, I believe that it is, at this time, (1) a
+	     worthwhile modification to the kernel, and (2) free of known
+	     issues which would argue against its inclusion.
+
+	 (d) While I have reviewed the patch and believe it to be sound, I
+	     do not (unless explicitly stated elsewhere) make any
+	     warranties or guarantees that it will achieve its stated
+	     purpose or function properly in any given situation.
+
+A Reviewed-by tag is a statement of opinion that the patch is an
+appropriate modification of the kernel without any remaining serious
+technical issues.  Any interested reviewer (who has done the work) can
+offer a Reviewed-by tag for a patch.  This tag serves to give credit to
+reviewers and to inform maintainers of the degree of review which has been
+done on the patch.  Reviewed-by: tags, when supplied by reviewers known to
+understand the subject area and to perform thorough reviews, will normally
+increase the likelihood of your patch getting into the kernel.
+
+A Suggested-by: tag indicates that the patch idea is suggested by the person
+named and ensures credit to the person for the idea. Please note that this
+tag should not be added without the reporter's permission, especially if the
+idea was not posted in a public forum. That said, if we diligently credit our
+idea reporters, they will, hopefully, be inspired to help us again in the
+future.
+
+A Fixes: tag indicates that the patch fixes an issue in a previous commit. It
+is used to make it easy to determine where a bug originated, which can help
+review a bug fix. This tag also assists the stable kernel team in determining
+which stable kernel versions should receive your fix. This is the preferred
+method for indicating a bug fixed by the patch. See :ref:`describe_changes`
+for more details.
+
+
+14) The canonical patch format
+------------------------------
+
+This section describes how the patch itself should be formatted.  Note
+that, if you have your patches stored in a ``git`` repository, proper patch
+formatting can be had with ``git format-patch``.  The tools cannot create
+the necessary text, though, so read the instructions below anyway.
+
+The canonical patch subject line is::
+
+    Subject: [PATCH 001/123] subsystem: summary phrase
+
+The canonical patch message body contains the following:
+
+  - A ``from`` line specifying the patch author (only needed if the person
+    sending the patch is not the author).
+
+  - An empty line.
+
+  - The body of the explanation, line wrapped at 75 columns, which will
+    be copied to the permanent changelog to describe this patch.
+
+  - The ``Signed-off-by:`` lines, described above, which will
+    also go in the changelog.
+
+  - A marker line containing simply ``---``.
+
+  - Any additional comments not suitable for the changelog.
+
+  - The actual patch (``diff`` output).
+
+The Subject line format makes it very easy to sort the emails
+alphabetically by subject line - pretty much any email reader will
+support that - since because the sequence number is zero-padded,
+the numerical and alphabetic sort is the same.
+
+The ``subsystem`` in the email's Subject should identify which
+area or subsystem of the kernel is being patched.
+
+The ``summary phrase`` in the email's Subject should concisely
+describe the patch which that email contains.  The ``summary
+phrase`` should not be a filename.  Do not use the same ``summary
+phrase`` for every patch in a whole patch series (where a ``patch
+series`` is an ordered sequence of multiple, related patches).
+
+Bear in mind that the ``summary phrase`` of your email becomes a
+globally-unique identifier for that patch.  It propagates all the way
+into the ``git`` changelog.  The ``summary phrase`` may later be used in
+developer discussions which refer to the patch.  People will want to
+google for the ``summary phrase`` to read discussion regarding that
+patch.  It will also be the only thing that people may quickly see
+when, two or three months later, they are going through perhaps
+thousands of patches using tools such as ``gitk`` or ``git log
+--oneline``.
+
+For these reasons, the ``summary`` must be no more than 70-75
+characters, and it must describe both what the patch changes, as well
+as why the patch might be necessary.  It is challenging to be both
+succinct and descriptive, but that is what a well-written summary
+should do.
+
+The ``summary phrase`` may be prefixed by tags enclosed in square
+brackets: "Subject: [PATCH <tag>...] <summary phrase>".  The tags are
+not considered part of the summary phrase, but describe how the patch
+should be treated.  Common tags might include a version descriptor if
+the multiple versions of the patch have been sent out in response to
+comments (i.e., "v1, v2, v3"), or "RFC" to indicate a request for
+comments.  If there are four patches in a patch series the individual
+patches may be numbered like this: 1/4, 2/4, 3/4, 4/4.  This assures
+that developers understand the order in which the patches should be
+applied and that they have reviewed or applied all of the patches in
+the patch series.
+
+A couple of example Subjects::
+
+    Subject: [PATCH 2/5] ext2: improve scalability of bitmap searching
+    Subject: [PATCH v2 01/27] x86: fix eflags tracking
+
+The ``from`` line must be the very first line in the message body,
+and has the form:
+
+        From: Original Author <author@example.com>
+
+The ``from`` line specifies who will be credited as the author of the
+patch in the permanent changelog.  If the ``from`` line is missing,
+then the ``From:`` line from the email header will be used to determine
+the patch author in the changelog.
+
+The explanation body will be committed to the permanent source
+changelog, so should make sense to a competent reader who has long
+since forgotten the immediate details of the discussion that might
+have led to this patch.  Including symptoms of the failure which the
+patch addresses (kernel log messages, oops messages, etc.) is
+especially useful for people who might be searching the commit logs
+looking for the applicable patch.  If a patch fixes a compile failure,
+it may not be necessary to include _all_ of the compile failures; just
+enough that it is likely that someone searching for the patch can find
+it.  As in the ``summary phrase``, it is important to be both succinct as
+well as descriptive.
+
+The ``---`` marker line serves the essential purpose of marking for patch
+handling tools where the changelog message ends.
+
+One good use for the additional comments after the ``---`` marker is for
+a ``diffstat``, to show what files have changed, and the number of
+inserted and deleted lines per file.  A ``diffstat`` is especially useful
+on bigger patches.  Other comments relevant only to the moment or the
+maintainer, not suitable for the permanent changelog, should also go
+here.  A good example of such comments might be ``patch changelogs``
+which describe what has changed between the v1 and v2 version of the
+patch.
+
+If you are going to include a ``diffstat`` after the ``---`` marker, please
+use ``diffstat`` options ``-p 1 -w 70`` so that filenames are listed from
+the top of the kernel source tree and don't use too much horizontal
+space (easily fit in 80 columns, maybe with some indentation).  (``git``
+generates appropriate diffstats by default.)
+
+See more details on the proper patch format in the following
+references.
+
+.. _explicit_in_reply_to:
+
+15) Explicit In-Reply-To headers
+--------------------------------
+
+It can be helpful to manually add In-Reply-To: headers to a patch
+(e.g., when using ``git send-email``) to associate the patch with
+previous relevant discussion, e.g. to link a bug fix to the email with
+the bug report.  However, for a multi-patch series, it is generally
+best to avoid using In-Reply-To: to link to older versions of the
+series.  This way multiple versions of the patch don't become an
+unmanageable forest of references in email clients.  If a link is
+helpful, you can use the https://lkml.kernel.org/ redirector (e.g., in
+the cover email text) to link to an earlier version of the patch series.
+
+
+16) Sending ``git pull`` requests
+---------------------------------
+
+If you have a series of patches, it may be most convenient to have the
+maintainer pull them directly into the subsystem repository with a
+``git pull`` operation.  Note, however, that pulling patches from a developer
+requires a higher degree of trust than taking patches from a mailing list.
+As a result, many subsystem maintainers are reluctant to take pull
+requests, especially from new, unknown developers.  If in doubt you can use
+the pull request as the cover letter for a normal posting of the patch
+series, giving the maintainer the option of using either.
+
+A pull request should have [GIT] or [PULL] in the subject line.  The
+request itself should include the repository name and the branch of
+interest on a single line; it should look something like::
+
+  Please pull from
+
+      git://jdelvare.pck.nerim.net/jdelvare-2.6 i2c-for-linus
+
+  to get these changes:
+
+A pull request should also include an overall message saying what will be
+included in the request, a ``git shortlog`` listing of the patches
+themselves, and a ``diffstat`` showing the overall effect of the patch series.
+The easiest way to get all this information together is, of course, to let
+``git`` do it for you with the ``git request-pull`` command.
+
+Some maintainers (including Linus) want to see pull requests from signed
+commits; that increases their confidence that the request actually came
+from you.  Linus, in particular, will not pull from public hosting sites
+like GitHub in the absence of a signed tag.
+
+The first step toward creating such tags is to make a GNUPG key and get it
+signed by one or more core kernel developers.  This step can be hard for
+new developers, but there is no way around it.  Attending conferences can
+be a good way to find developers who can sign your key.
+
+Once you have prepared a patch series in ``git`` that you wish to have somebody
+pull, create a signed tag with ``git tag -s``.  This will create a new tag
+identifying the last commit in the series and containing a signature
+created with your private key.  You will also have the opportunity to add a
+changelog-style message to the tag; this is an ideal place to describe the
+effects of the pull request as a whole.
+
+If the tree the maintainer will be pulling from is not the repository you
+are working from, don't forget to push the signed tag explicitly to the
+public tree.
+
+When generating your pull request, use the signed tag as the target.  A
+command like this will do the trick::
+
+  git request-pull master git://my.public.tree/linux.git my-signed-tag

 Virtual TPM Proxy Driver for Linux Containers
+=============================================
 
-Authors: Stefan Berger (IBM)
+| Authors:
+| Stefan Berger <stefanb@linux.vnet.ibm.com>
 
 This document describes the virtual Trusted Platform Module (vTPM)
 proxy device driver for Linux containers.
 
-INTRODUCTION
-------------
+Introduction
+============
 
 The goal of this work is to provide TPM functionality to each Linux
 container. This allows programs to interact with a TPM in a container
 the same way they interact with a TPM on the physical system. Each
 container gets its own unique, emulated, software TPM.
 
-
-DESIGN
-------
+Design
+======
 
 To make an emulated software TPM available to each container, the container
 management stack needs to create a device pair consisting of a client TPM
-character device /dev/tpmX (with X=0,1,2...) and a 'server side' file
+character device ``/dev/tpmX`` (with X=0,1,2...) and a 'server side' file
 descriptor. The former is moved into the container by creating a character
 device with the appropriate major and minor numbers while the file descriptor
 is passed to the TPM emulator. Software inside the container can then send
 TPM commands using the character device and the emulator will receive the
 commands via the file descriptor and use it for sending back responses.
 
-To support this, the virtual TPM proxy driver provides a device /dev/vtpmx
+To support this, the virtual TPM proxy driver provides a device ``/dev/vtpmx``
 that is used to create device pairs using an ioctl. The ioctl takes as
 an input flags for configuring the device. The flags  for example indicate
 whether TPM 1.2 or TPM 2 functionality is supported by the TPM emulator.
 The result of the ioctl are the file descriptor for the 'server side'
 as well as the major and minor numbers of the character device that was created.
-Besides that the number of the TPM character device is return. If for
-example /dev/tpm10 was created, the number (dev_num) 10 is returned.
-
-The following is the data structure of the TPM_PROXY_IOC_NEW_DEV ioctl:
-
-struct vtpm_proxy_new_dev {
-	__u32 flags;         /* input */
-	__u32 tpm_num;       /* output */
-	__u32 fd;            /* output */
-	__u32 major;         /* output */
-	__u32 minor;         /* output */
-};
-
-Note that if unsupported flags are passed to the device driver, the ioctl will
-fail and errno will be set to EOPNOTSUPP. Similarly, if an unsupported ioctl is
-called on the device driver, the ioctl will fail and errno will be set to
-ENOTTY.
-
-See /usr/include/linux/vtpm_proxy.h for definitions related to the public interface
-of this vTPM device driver.
+Besides that the number of the TPM character device is returned. If for
+example ``/dev/tpm10`` was created, the number (``dev_num``) 10 is returned.
 
 Once the device has been created, the driver will immediately try to talk
 to the TPM. All commands from the driver can be read from the file descriptor
 returned by the ioctl. The commands should be responded to immediately.
 
-Depending on the version of TPM the following commands will be sent by the
-driver:
+UAPI
+====
 
-- TPM 1.2:
-  - the driver will send a TPM_Startup command to the TPM emulator
-  - the driver will send commands to read the command durations and
-    interface timeouts from the TPM emulator
-- TPM 2:
-  - the driver will send a TPM2_Startup command to the TPM emulator
+.. kernel-doc:: include/uapi/linux/vtpm_proxy.h
 
-The TPM device /dev/tpmX will only appear if all of the relevant commands
-were responded to properly.

+Advanced Linux Sound Architecture - Driver Configuration guide
+==============================================================
+
+
+Kernel Configuration
+====================
+
+To enable ALSA support you need at least to build the kernel with
+primary sound card support (``CONFIG_SOUND``).  Since ALSA can emulate
+OSS, you don't have to choose any of the OSS modules.
+
+Enable "OSS API emulation" (``CONFIG_SND_OSSEMUL``) and both OSS mixer
+and PCM supports if you want to run OSS applications with ALSA.
+
+If you want to support the WaveTable functionality on cards such as
+SB Live! then you need to enable "Sequencer support"
+(``CONFIG_SND_SEQUENCER``).
+
+To make ALSA debug messages more verbose, enable the "Verbose printk"
+and "Debug" options.  To check for memory leaks, turn on "Debug memory"
+too.  "Debug detection" will add checks for the detection of cards.
+
+Please note that all the ALSA ISA drivers support the Linux isapnp API
+(if the card supports ISA PnP).  You don't need to configure the cards
+using isapnptools.
+
+
+Module parameters
+=================
+
+The user can load modules with options. If the module supports more than
+one card and you have more than one card of the same type then you can
+specify multiple values for the option separated by commas.
+
+
+Module snd
+----------
+
+The core ALSA module.  It is used by all ALSA card drivers.
+It takes the following options which have global effects.
+
+major
+    major number for sound driver;
+    Default: 116
+cards_limit
+    limiting card index for auto-loading (1-8);
+    Default: 1;
+    For auto-loading more than one card, specify this option
+    together with snd-card-X aliases.
+slots
+    Reserve the slot index for the given driver;
+    This option takes multiple strings.
+    See `Module Autoloading Support`_ section for details.
+debug
+    Specifies the debug message level;
+    (0 = disable debug prints, 1 = normal debug messages,
+    2 = verbose debug messages);
+    This option appears only when ``CONFIG_SND_DEBUG=y``.
+    This option can be dynamically changed via sysfs
+    /sys/modules/snd/parameters/debug file.
+  
+Module snd-pcm-oss
+------------------
+
+The PCM OSS emulation module.
+This module takes options which change the mapping of devices.
+
+dsp_map
+    PCM device number maps assigned to the 1st OSS device;
+    Default: 0
+adsp_map
+    PCM device number maps assigned to the 2st OSS device;
+    Default: 1
+nonblock_open
+    Don't block opening busy PCM devices;
+    Default: 1
+
+For example, when ``dsp_map=2``, /dev/dsp will be mapped to PCM #2 of
+the card #0.  Similarly, when ``adsp_map=0``, /dev/adsp will be mapped
+to PCM #0 of the card #0.
+For changing the second or later card, specify the option with
+commas, such like ``dsp_map=0,1``.
+
+``nonblock_open`` option is used to change the behavior of the PCM
+regarding opening the device.  When this option is non-zero,
+opening a busy OSS PCM device won't be blocked but return
+immediately with EAGAIN (just like O_NONBLOCK flag).
+    
+Module snd-rawmidi
+------------------
+
+This module takes options which change the mapping of devices.
+similar to those of the snd-pcm-oss module.
+
+midi_map
+    MIDI device number maps assigned to the 1st OSS device;
+    Default: 0
+amidi_map
+    MIDI device number maps assigned to the 2st OSS device;
+    Default: 1
+
+Common parameters for top sound card modules
+--------------------------------------------
+
+Each of top level sound card module takes the following options.
+
+index
+    index (slot #) of sound card;
+    Values: 0 through 31 or negative;
+    If nonnegative, assign that index number;
+    if negative, interpret as a bitmask of permissible indices;
+    the first free permitted index is assigned;
+    Default: -1
+id
+    card ID (identifier or name);
+    Can be up to 15 characters long;
+    Default: the card type;
+    A directory by this name is created under /proc/asound/
+    containing information about the card;
+    This ID can be used instead of the index number in
+    identifying the card
+enable
+    enable card;
+    Default: enabled, for PCI and ISA PnP cards
+
+Module snd-adlib
+----------------
+
+Module for AdLib FM cards.
+
+port
+    port # for OPL chip
+
+This module supports multiple cards. It does not support autoprobe, so
+the port must be specified. For actual AdLib FM cards it will be 0x388.
+Note that this card does not have PCM support and no mixer; only FM
+synthesis.
+
+Make sure you have ``sbiload`` from the alsa-tools package available and,
+after loading the module, find out the assigned ALSA sequencer port
+number through ``sbiload -l``.
+
+Example output:
+::
+
+      Port     Client name                       Port name
+      64:0     OPL2 FM synth                     OPL2 FM Port
+
+Load the ``std.sb`` and ``drums.sb`` patches also supplied by ``sbiload``:
+::
+
+      sbiload -p 64:0 std.sb drums.sb
+
+If you use this driver to drive an OPL3, you can use ``std.o3`` and ``drums.o3``
+instead. To have the card produce sound, use ``aplaymidi`` from alsa-utils:
+::
+
+      aplaymidi -p 64:0 foo.mid
+
+Module snd-ad1816a
+------------------
+
+Module for sound cards based on Analog Devices AD1816A/AD1815 ISA chips.
+
+clockfreq
+    Clock frequency for AD1816A chip (default = 0, 33000Hz)
+    
+This module supports multiple cards, autoprobe and PnP.
+    
+Module snd-ad1848
+-----------------
+
+Module for sound cards based on AD1848/AD1847/CS4248 ISA chips.
+
+port
+    port # for AD1848 chip
+irq
+    IRQ # for AD1848  chip
+dma1
+    DMA # for AD1848 chip (0,1,3)
+    
+This module supports multiple cards.  It does not support autoprobe
+thus main port must be specified!!! Other ports are optional.
+    
+The power-management is supported.
+
+Module snd-ad1889
+-----------------
+
+Module for Analog Devices AD1889 chips.

+Development and reverse engineering work is being coordinated at
+http://savannah.nongnu.org/projects/openvortex/
+SPDIF output has a copy of the AC97 codec output, unless you use the
+``spdif`` pcm device, which allows raw data passthru.
+The hardware EQ hardware and SPDIF is only present in the Vortex2 and 
+Advantage.
+

+fm_port
+    port # for OPL3 (0x388), -1 = disabled (default)
+
+This module supports multiple cards. It does not support autoprobe:
+``port``, ``wss_port``, ``irq`` and ``dma1`` have to be specified.
+The other values are optional.
+
+``port`` needs to match the BASE ADDRESS jumper on the card (0x220 or 0x240)
+or the value stored in the card's EEPROM for cards that have an EEPROM and
+their "CONFIG MODE" jumper set to "EEPROM SETTING". The other values can
+be chosen freely from the options enumerated above.
+
+If ``dma2`` is specified and different from ``dma1``, the card will operate in
+full-duplex mode. When ``dma1=3``, only ``dma2=0`` is valid and the only way to
+enable capture since only channels 0 and 1 are available for capture.
+
+Generic settings are ``port=0x220 wss_port=0x530 irq=10 dma1=1 dma2=0
+mpu_port=0x330 mpu_irq=9 fm_port=0x388``.
+
+Whatever IRQ and DMA channels you pick, be sure to reserve them for
+legacy ISA in your BIOS.

+    slots regardless what hardware reports back
+probe_only
+    Only probing and no codec initialization (default=off);
+    Useful to check the initial codec status for debugging
+bdl_pos_adj
+    Specifies the DMA IRQ timing delay in samples.
+    Passing -1 will make the driver to choose the appropriate
+    value based on the controller chip.
+patch
+    Specifies the early "patch" files to modify the HD-audio setup
+    before initializing the codecs.
+    This option is available only when ``CONFIG_SND_HDA_PATCH_LOADER=y``
+    is set.  See hd-audio/notes.rst for details.
+beep_mode
+    Selects the beep registration mode (0=off, 1=on);
+    default value is set via ``CONFIG_SND_HDA_INPUT_BEEP_MODE`` kconfig.
+
+[Single (global) options]
+
+single_cmd
+    Use single immediate commands to communicate with codecs
+    (for debugging only)
+enable_msi
+    Enable Message Signaled Interrupt (MSI) (default = off)
+power_save
+    Automatic power-saving timeout (in second, 0 = disable)
+power_save_controller
+    Reset HD-audio controller in power-saving mode (default = on)
+align_buffer_size
+    Force rounding of buffer/period sizes to multiples of 128 bytes.
+    This is more efficient in terms of memory access but isn't
+    required by the HDA spec and prevents users from specifying
+    exact period/buffer sizes. (default = on)
+snoop
+    Enable/disable snooping (default = on)
+
+This module supports multiple cards and autoprobe.
+
+See hd-audio/notes.rst for more details about HD-audio driver.
+
+Each codec may have a model table for different configurations.
+If your machine isn't listed there, the default (usually minimal)
+configuration is set up.  You can pass ``model=<name>`` option to
+specify a certain model in such a case.  There are different
+models depending on the codec chip.  The list of available models
+is found in hd-audio/models.rst.
+
+The model name ``generic`` is treated as a special case.  When this
+model is given, the driver uses the generic codec parser without
+"codec-patch".  It's sometimes good for testing and debugging.
+
+If the default configuration doesn't work and one of the above
+matches with your device, report it together with alsa-info.sh
+output (with ``--no-upload`` option) to kernel bugzilla or alsa-devel
+ML (see the section `Links and Addresses`_).
+
+``power_save`` and ``power_save_controller`` options are for power-saving
+mode.  See powersave.txt for details.
+
+Note 2: If you get click noises on output, try the module option
+``position_fix=1`` or ``2``.  ``position_fix=1`` will use the SD_LPIB
+register value without FIFO size correction as the current
+DMA pointer.  ``position_fix=2`` will make the driver to use
+the position buffer instead of reading SD_LPIB register.
+(Usually SD_LPIB register is more accurate than the
+position buffer.)
+
+``position_fix=3`` is specific to VIA devices.  The position
+of the capture stream is checked from both LPIB and POSBUF
+values.  ``position_fix=4`` is a combination mode, using LPIB
+for playback and POSBUF for capture.
+
+NB: If you get many ``azx_get_response timeout`` messages at
+loading, it's likely a problem of interrupts (e.g. ACPI irq
+routing).  Try to boot with options like ``pci=noacpi``.  Also, you
+can try ``single_cmd=1`` module option.  This will switch the
+communication method between HDA controller and codecs to the
+single immediate commands instead of CORB/RIRB.  Basically, the
+single command mode is provided only for BIOS, and you won't get
+unsolicited events, too.  But, at least, this works independently
+from the irq.  Remember this is a last resort, and should be
+avoided as much as possible...
+
+MORE NOTES ON ``azx_get_response timeout`` PROBLEMS:
+On some hardware, you may need to add a proper probe_mask option
+to avoid the ``azx_get_response timeout`` problem above, instead.
+This occurs when the access to non-existing or non-working codec slot
+(likely a modem one) causes a stall of the communication via HD-audio
+bus.  You can see which codec slots are probed by enabling
+``CONFIG_SND_DEBUG_VERBOSE``, or simply from the file name of the codec
+proc files.  Then limit the slots to probe by probe_mask option.
+For example, ``probe_mask=1`` means to probe only the first slot, and
+``probe_mask=4`` means only the third slot.
+
+The power-management is supported.

+Module snd-hdsp
+---------------
+
+Module for RME Hammerfall DSP audio interface(s)

+The firmware data is found in alsa-firmware package.
+
+Note: snd-page-alloc module does the job which snd-hammerfall-mem
+module did formerly.  It will allocate the buffers in advance
+when any HDSP cards are found.  To make the buffer
+allocation sure, load snd-page-alloc module in the early

+reset_workaround
+    enable AC97 RESET workaround for some laptops
+reset_workaround2
+    enable extended AC97 RESET workaround for some other laptops
+
+This module supports one chip and autoprobe.
+
+The power-management is supported.
+
+Note: on some notebooks the buffer address cannot be detected
+automatically, or causes hang-up during initialization.
+In such a case, specify the buffer top address explicitly via
+the buffer_top option.
+For example,
+Sony F250: buffer_top=0x25a800
+Sony F270: buffer_top=0x272800
+The driver supports only ac97 codec.  It's possible to force
+to initialize/use ac97 although it's not detected.  In such a
+case, use ``force_ac97=1`` option - but *NO* guarantee whether it
+works!
+
+Note: The NM256 chip can be linked internally with non-AC97
+codecs.  This driver supports only the AC97 codec, and won't work
+with machines with other (most likely CS423x or OPL3SAx) chips,
+even though the device is detected in lspci.  In such a case, try
+other drivers, e.g. snd-cs4232 or snd-opl3sa2.  Some has ISA-PnP
+but some doesn't have ISA PnP.  You'll need to specify ``isapnp=0``
+and proper hardware parameters in the case without ISA PnP.
+
+Note: some laptops need a workaround for AC97 RESET.  For the
+known hardware like Dell Latitude LS and Sony PCG-F305, this
+workaround is enabled automatically.  For other laptops with a
+hard freeze, you can try ``reset_workaround=1`` option.
+
+Note: Dell Latitude CSx laptops have another problem regarding
+AC97 RESET.  On these laptops, reset_workaround2 option is
+turned on as default.  This option is worth to try if the
+previous reset_workaround option doesn't help.
+
+Note: This driver is really crappy.  It's a porting from the
+OSS driver, which is a result of black-magic reverse engineering.
+The detection of codec will fail if the driver is loaded *after*
+X-server as described above.  You might be able to force to load
+the module, but it may result in hang-up.   Hence, make sure that
+you load this module *before* X if you encounter this kind of
+problem.

+dma2
+    DMA2 # for CS4232 PCM interface.
+
+The below are options for wavefront_synth features:
+
+wf_raw
+    Assume that we need to boot the OS (default:no);
+    If yes, then during driver loading, the state of the board is
+    ignored, and we reset the board and load the firmware anyway.
+fx_raw
+    Assume that the FX process needs help (default:yes);
+    If false, we'll leave the FX processor in whatever state it is
+    when the driver is loaded.  The default is to download the
+    microprogram and associated coefficients to set it up for
+    "default" operation, whatever that means.
+debug_default
+    Debug parameters for card initialization
+wait_usecs
+    How long to wait without sleeping, usecs (default:150);
+    This magic number seems to give pretty optimal throughput
+    based on my limited experimentation. 
+    If you want to play around with it and find a better value, be
+    my guest. Remember, the idea is to get a number that causes us
+    to just busy wait for as many WaveFront commands as possible,
+    without coming up with a number so large that we hog the whole
+    CPU. 
+    Specifically, with this number, out of about 134,000 status
+    waits, only about 250 result in a sleep. 
+sleep_interval
+    How long to sleep when waiting for reply (default: 100)
+sleep_tries
+    How many times to try sleeping during a wait (default: 50)
+ospath
+    Pathname to processed ICS2115 OS firmware (default:wavefront.os);
+    The path name of the ISC2115 OS firmware.  In the recent
+    version, it's handled via firmware loader framework, so it
+    must be installed in the proper path, typically,
+    /lib/firmware.
+reset_time
+    How long to wait for a reset to take effect (default:2)
+ramcheck_time
+    How many seconds to wait for the RAM test (default:20)
+osrun_time
+    How many seconds to wait for the ICS2115 OS (default:10)
+
+This module supports multiple cards and ISA PnP.
+
+Note: the firmware file ``wavefront.os`` was located in the earlier
+version in /etc.  Now it's loaded via firmware loader, and
+must be in the proper firmware path, such as /lib/firmware.
+Copy (or symlink) the file appropriately if you get an error
+regarding firmware downloading after upgrading the kernel.

+------------------
+
+Module for AC'97 motherboards based on VIA 82C686A/686B, 8233, 8233A,
+8233C, 8235, 8237 (south) bridge.
+
+mpu_port
+    0x300,0x310,0x320,0x330, otherwise obtain BIOS setup
+    [VIA686A/686B only]
+joystick
+    Enable joystick (default off) [VIA686A/686B only]
+ac97_clock
+    AC'97 codec clock base (default 48000Hz)
+dxs_support
+    support DXS channels, 0 = auto (default), 1 = enable, 2 = disable,
+    3 = 48k only, 4 = no VRA, 5 = enable any sample rate and different
+    sample rates on different channels [VIA8233/C, 8235, 8237 only]
+ac97_quirk
+    AC'97 workaround for strange hardware;
+    See `AC97 Quirk Option`_ section below.
+
+This module supports one chip and autoprobe.
+
+Note: on some SMP motherboards like MSI 694D the interrupts might
+not be generated properly.  In such a case, please try to
+set the SMP (or MPS) version on BIOS to 1.1 instead of
+default value 1.4.  Then the interrupt number will be
+assigned under 15. You might also upgrade your BIOS.
+
+Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
+channels as the first PCM.  On these channels, up to 4
+streams can be played at the same time, and the controller
+can perform sample rate conversion with separate rates for
+each channel.
+As default (``dxs_support = 0``), 48k fixed rate is chosen
+except for the known devices since the output is often
+noisy except for 48k on some mother boards due to the
+bug of BIOS.
+Please try once ``dxs_support=5`` and if it works on other
+sample rates (e.g. 44.1kHz of mp3 playback), please let us
+know the PCI subsystem vendor/device id's (output of
+``lspci -nv``).
+If ``dxs_support=5`` does not work, try ``dxs_support=4``; if it
+doesn't work too, try dxs_support=1.  (dxs_support=1 is
+usually for old motherboards.  The correct implemented
+board should work with 4 or 5.)  If it still doesn't
+work and the default setting is ok, ``dxs_support=3`` is the
+right choice.  If the default setting doesn't work at all,
+try ``dxs_support=2`` to disable the DXS channels.
+In any cases, please let us know the result and the
+subsystem vendor/device ids.  See `Links and Addresses`_
+below.
+
+Note: for the MPU401 on VIA823x, use snd-mpu401 driver
+additionally.  The mpu_port option is for VIA686 chips only.
+
+The power-management is supported.
+

+
+This module supports multiple cards.
+
+When the driver is compiled as a module and the hotplug firmware
+is supported, the firmware data is loaded via hotplug automatically.
+Install the necessary firmware files in alsa-firmware package.
+When no hotplug fw loader is available, you need to load the
+firmware via vxloader utility in alsa-tools package.  To invoke
+vxloader automatically, add the following to /etc/modprobe.d/alsa.conf
+
+::
+
+  install snd-vx222 /sbin/modprobe --first-time -i snd-vx222\
+    && /usr/bin/vxloader
+
+(for 2.2/2.4 kernels, add ``post-install /usr/bin/vxloader`` to
+/etc/modules.conf, instead.)
+IBL size defines the interrupts period for PCM.  The smaller size
+gives smaller latency but leads to more CPU consumption, too.
+The size is usually aligned to 126.  As default (=0), the smallest
+size is chosen.  The possible IBL values can be found in
+/proc/asound/cardX/vx-status proc file.
+
+The power-management is supported.

+ibl
+    Capture IBL size. (default = 0, minimum size)
+
+This module supports multiple cards.  The module is compiled only when
+PCMCIA is supported on kernel.
+
+With the older 2.6.x kernel, to activate the driver via the card
+manager, you'll need to set up /etc/pcmcia/vxpocket.conf.  See the
+sound/pcmcia/vx/vxpocket.c.  2.6.13 or later kernel requires no
+longer require a config file.
+
+When the driver is compiled as a module and the hotplug firmware
+is supported, the firmware data is loaded via hotplug automatically.
+Install the necessary firmware files in alsa-firmware package.
+When no hotplug fw loader is available, you need to load the
+firmware via vxloader utility in alsa-tools package.
+
+About capture IBL, see the description of snd-vx222 module.
+
+Note: snd-vxp440 driver is merged to snd-vxpocket driver since
+ALSA 1.0.10.
+
+The power-management is supported.

+
+
+AC97 Quirk Option
+=================
+
+The ac97_quirk option is used to enable/override the workaround for
+specific devices on drivers for on-board AC'97 controllers like
+snd-intel8x0.  Some hardware have swapped output pins between Master
+and Headphone, or Surround (thanks to confusion of AC'97
+specifications from version to version :-)
+
+The driver provides the auto-detection of known problematic devices,
+but some might be unknown or wrongly detected.  In such a case, pass
+the proper value with this option.
+
+The following strings are accepted:
+
+default
+    Don't override the default setting
+none
+    Disable the quirk
+hp_only
+    Bind Master and Headphone controls as a single control
+swap_hp
+    Swap headphone and master controls
+swap_surround
+    Swap master and surround controls
+ad_sharing
+    For AD1985, turn on OMS bit and use headphone
+alc_jack
+    For ALC65x, turn on the jack sense mode
+inv_eapd
+    Inverted EAPD implementation
+mute_led
+    Bind EAPD bit for turning on/off mute LED
+
+For backward compatibility, the corresponding integer value -1, 0, ...
+are  accepted, too.
+
+For example, if ``Master`` volume control has no effect on your device
+but only ``Headphone`` does, pass ac97_quirk=hp_only module option.
+
+
+Configuring Non-ISAPNP Cards
+============================
+
+When the kernel is configured with ISA-PnP support, the modules
+supporting the isapnp cards will have module options ``isapnp``.
+If this option is set, *only* the ISA-PnP devices will be probed.
+For probing the non ISA-PnP cards, you have to pass ``isapnp=0`` option
+together with the proper i/o and irq configuration.
+
+When the kernel is configured without ISA-PnP support, isapnp option
+will be not built in.
+
+
+Module Autoloading Support
+==========================
+
+The ALSA drivers can be loaded automatically on demand by defining
+module aliases.  The string ``snd-card-%1`` is requested for ALSA native
+devices where ``%i`` is sound card number from zero to seven.
+
+To auto-load an ALSA driver for OSS services, define the string
+``sound-slot-%i`` where ``%i`` means the slot number for OSS, which
+corresponds to the card index of ALSA.  Usually, define this
+as the same card module.
+
+An example configuration for a single emu10k1 card is like below:
+::
+
+    ----- /etc/modprobe.d/alsa.conf
+    alias snd-card-0 snd-emu10k1
+    alias sound-slot-0 snd-emu10k1
+    ----- /etc/modprobe.d/alsa.conf
+
+The available number of auto-loaded sound cards depends on the module
+option ``cards_limit`` of snd module.  As default it's set to 1.
+To enable the auto-loading of multiple cards, specify the number of
+sound cards in that option.
+
+When multiple cards are available, it'd better to specify the index
+number for each card via module option, too, so that the order of
+cards is kept consistent.
+
+An example configuration for two sound cards is like below:
+::
+
+    ----- /etc/modprobe.d/alsa.conf
+    # ALSA portion
+    options snd cards_limit=2
+    alias snd-card-0 snd-interwave
+    alias snd-card-1 snd-ens1371
+    options snd-interwave index=0
+    options snd-ens1371 index=1
+    # OSS/Free portion
+    alias sound-slot-0 snd-interwave
+    alias sound-slot-1 snd-ens1371
+    ----- /etc/modprobe.d/alsa.conf
+
+In this example, the interwave card is always loaded as the first card
+(index 0) and ens1371 as the second (index 1).
+
+Alternative (and new) way to fixate the slot assignment is to use
+``slots`` option of snd module.  In the case above, specify like the
+following: 
+::
+
+    options snd slots=snd-interwave,snd-ens1371
+
+Then, the first slot (#0) is reserved for snd-interwave driver, and
+the second (#1) for snd-ens1371.  You can omit index option in each
+driver if slots option is used (although you can still have them at
+the same time as long as they don't conflict).
+
+The slots option is especially useful for avoiding the possible
+hot-plugging and the resultant slot conflict.  For example, in the
+case above again, the first two slots are already reserved.  If any
+other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
+snd-ens1371, it will be assigned to the third or later slot.
+
+When a module name is given with '!', the slot will be given for any
+modules but that name.  For example, ``slots=!snd-pcsp`` will reserve
+the first slot for any modules but snd-pcsp. 
+
+
+ALSA PCM devices to OSS devices mapping
+=======================================
+::
+
+    /dev/snd/pcmC0D0[c|p]  -> /dev/audio0 (/dev/audio) -> minor 4
+    /dev/snd/pcmC0D0[c|p]  -> /dev/dsp0 (/dev/dsp)     -> minor 3
+    /dev/snd/pcmC0D1[c|p]  -> /dev/adsp0 (/dev/adsp)   -> minor 12
+    /dev/snd/pcmC1D0[c|p]  -> /dev/audio1              -> minor 4+16 = 20
+    /dev/snd/pcmC1D0[c|p]  -> /dev/dsp1                -> minor 3+16 = 19
+    /dev/snd/pcmC1D1[c|p]  -> /dev/adsp1               -> minor 12+16 = 28
+    /dev/snd/pcmC2D0[c|p]  -> /dev/audio2              -> minor 4+32 = 36
+    /dev/snd/pcmC2D0[c|p]  -> /dev/dsp2                -> minor 3+32 = 39
+    /dev/snd/pcmC2D1[c|p]  -> /dev/adsp2               -> minor 12+32 = 44
+
+The first number from ``/dev/snd/pcmC{X}D{Y}[c|p]`` expression means
+sound card number and second means device number.  The ALSA devices
+have either ``c`` or ``p`` suffix indicating the direction, capture and
+playback, respectively.
+
+Please note that the device mapping above may be varied via the module
+options of snd-pcm-oss module.
+
+
+Proc interfaces (/proc/asound)
+==============================
+
+/proc/asound/card#/pcm#[cp]/oss
+-------------------------------
+erase
+    erase all additional information about OSS applications
+
+<app_name> <fragments> <fragment_size> [<options>]
+    <app_name>
+	name of application with (higher priority) or without path
+    <fragments>
+	 number of fragments or zero if auto
+    <fragment_size>
+	 size of fragment in bytes or zero if auto
+    <options>
+	optional parameters
+
+	disable
+	    the application tries to open a pcm device for
+	    this channel but does not want to use it.
+	    (Cause a bug or mmap needs)
+	    It's good for Quake etc...
+	direct
+	    don't use plugins
+	block
+	     force block mode (rvplayer)
+	non-block
+	    force non-block mode
+	whole-frag
+	    write only whole fragments (optimization affecting
+	    playback only)
+	no-silence
+	    do not fill silence ahead to avoid clicks
+	buggy-ptr
+	    Returns the whitespace blocks in GETOPTR ioctl
+	    instead of filled blocks
+
+Example:
+::
+
+    echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
+    echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
+    echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
+
+
+Early Buffer Allocation
+=======================
+
+Some drivers (e.g. hdsp) require the large contiguous buffers, and
+sometimes it's too late to find such spaces when the driver module is
+actually loaded due to memory fragmentation.  You can pre-allocate the
+PCM buffers by loading snd-page-alloc module and write commands to its
+proc file in prior, for example, in the early boot stage like
+``/etc/init.d/*.local`` scripts.
+
+Reading the proc file /proc/drivers/snd-page-alloc shows the current
+usage of page allocation.  In writing, you can send the following
+commands to the snd-page-alloc driver:
+
+* add VENDOR DEVICE MASK SIZE BUFFERS
+
+VENDOR and DEVICE are PCI vendor and device IDs.  They take
+integer numbers (0x prefix is needed for the hex).
+MASK is the PCI DMA mask.  Pass 0 if not restricted.
+SIZE is the size of each buffer to allocate.  You can pass
+k and m suffix for KB and MB.  The max number is 16MB.
+BUFFERS is the number of buffers to allocate.  It must be greater
+than 0.  The max number is 4.
+
+* erase
+
+This will erase the all pre-allocated buffers which are not in
+use.

-		Advanced Linux Sound Architecture - Driver
-		==========================================
-			    Configuration guide
-
-
-Kernel Configuration
-====================
-
-To enable ALSA support you need at least to build the kernel with
-primary sound card support (CONFIG_SOUND).  Since ALSA can emulate OSS,
-you don't have to choose any of the OSS modules.
-
-Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and
-PCM supports if you want to run OSS applications with ALSA.
-
-If you want to support the WaveTable functionality on cards such as
-SB Live! then you need to enable "Sequencer support"
-(CONFIG_SND_SEQUENCER).
-
-To make ALSA debug messages more verbose, enable the "Verbose printk"
-and "Debug" options.  To check for memory leaks, turn on "Debug memory"
-too.  "Debug detection" will add checks for the detection of cards.
-
-Please note that all the ALSA ISA drivers support the Linux isapnp API
-(if the card supports ISA PnP).  You don't need to configure the cards
-using isapnptools.
-
-
-Creating ALSA devices
-=====================
-
-This depends on your distribution, but normally you use the /dev/MAKEDEV
-script to create the necessary device nodes.  On some systems you use a
-script named 'snddevices'.
-
-
-Module parameters
-=================
-
-The user can load modules with options. If the module supports more than
-one card and you have more than one card of the same type then you can
-specify multiple values for the option separated by commas.
-
-Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed.
-
-  Module snd
-  ----------
-
-    The core ALSA module.  It is used by all ALSA card drivers.
-    It takes the following options which have global effects.
-
-    major	- major number for sound driver
-		- Default: 116
-    cards_limit
-		- limiting card index for auto-loading (1-8)
-		- Default: 1
-		- For auto-loading more than one card, specify this
-		  option together with snd-card-X aliases.
-    slots	- Reserve the slot index for the given driver.
-		  This option takes multiple strings.		
-		  See "Module Autoloading Support" section for details.
-    debug	- Specifies the debug message level
-		  (0 = disable debug prints, 1 = normal debug messages,
-		   2 = verbose debug messages)
-		  This option appears only when CONFIG_SND_DEBUG=y.
-		  This option can be dynamically changed via sysfs
-		  /sys/modules/snd/parameters/debug file.
-  
-  Module snd-pcm-oss
-  ------------------
-
-    The PCM OSS emulation module.
-    This module takes options which change the mapping of devices.
-
-    dsp_map	- PCM device number maps assigned to the 1st OSS device.
-		- Default: 0
-    adsp_map	- PCM device number maps assigned to the 2st OSS device.
-		- Default: 1
-    nonblock_open
-		- Don't block opening busy PCM devices.  Default: 1
-
-    For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of
-    the card #0.  Similarly, when adsp_map=0, /dev/adsp will be mapped
-    to PCM #0 of the card #0.
-    For changing the second or later card, specify the option with
-    commas, such like "dsp_map=0,1".
-
-    nonblock_open option is used to change the behavior of the PCM
-    regarding opening the device.  When this option is non-zero,
-    opening a busy OSS PCM device won't be blocked but return
-    immediately with EAGAIN (just like O_NONBLOCK flag).
-    
-  Module snd-rawmidi
-  ------------------
-
-    This module takes options which change the mapping of devices.
-    similar to those of the snd-pcm-oss module.
-
-    midi_map	- MIDI device number maps assigned to the 1st OSS device.
-		- Default: 0
-    amidi_map	- MIDI device number maps assigned to the 2st OSS device.
-		- Default: 1
-
-  Common parameters for top sound card modules
-  --------------------------------------------
-
-    Each of top level sound card module takes the following options.
-
-    index	- index (slot #) of sound card
-		- Values: 0 through 31 or negative
-		- If nonnegative, assign that index number
-                - if negative, interpret as a bitmask of permissible
-		  indices; the first free permitted index is assigned
-		- Default: -1
-    id		- card ID (identifier or name)
-		- Can be up to 15 characters long
-		- Default: the card type
-		- A directory by this name is created under /proc/asound/
-		  containing information about the card
-		- This ID can be used instead of the index number in
-		  identifying the card
-    enable  	- enable card
-		- Default: enabled, for PCI and ISA PnP cards
-
-  Module snd-adlib
-  ----------------
-
-    Module for AdLib FM cards.
-
-    port	- port # for OPL chip
-
-    This module supports multiple cards. It does not support autoprobe, so
-    the port must be specified. For actual AdLib FM cards it will be 0x388.
-    Note that this card does not have PCM support and no mixer; only FM
-    synthesis.
-
-    Make sure you have "sbiload" from the alsa-tools package available and,
-    after loading the module, find out the assigned ALSA sequencer port
-    number through "sbiload -l". Example output:
-
-      Port     Client name                       Port name
-      64:0     OPL2 FM synth                     OPL2 FM Port
-
-    Load the std.sb and drums.sb patches also supplied by sbiload:
-
-      sbiload -p 64:0 std.sb drums.sb
-
-    If you use this driver to drive an OPL3, you can use std.o3 and drums.o3
-    instead. To have the card produce sound, use aplaymidi from alsa-utils:
-
-      aplaymidi -p 64:0 foo.mid
-

-    irq		- IRQ # for AD1848  chip
-    dma1	- DMA # for AD1848 chip (0,1,3)
-    
-    This module supports multiple cards.  It does not support autoprobe
-    thus main port must be specified!!! Other ports are optional.
-    
-    The power-management is supported.
-
-  Module snd-ad1889
-  -----------------
-
-    Module for Analog Devices AD1889 chips.

-
-    This module supports all ADB PCM channels, ac97 mixer, SPDIF, hardware
-    EQ, mpu401, gameport. A3D and wavetable support are still in development.
-    Development and reverse engineering work is being coordinated at
-    http://savannah.nongnu.org/projects/openvortex/
-    SPDIF output has a copy of the AC97 codec output, unless you use the
-    "spdif" pcm device, which allows raw data passthru.
-    The hardware EQ hardware and SPDIF is only present in the Vortex2 and 
-    Advantage.
-
-    Note: Some ALSA mixer applications don't handle the SPDIF sample rate 
-           control correctly. If you have problems regarding this, try
-           another ALSA compliant mixer (alsamixer works).
-
-  Module snd-azt1605
-  ------------------
-
-    Module for Aztech Sound Galaxy soundcards based on the Aztech AZT1605
-    chipset.

-    wss_port	- port # for WSS (0x530,0x604,0xe80,0xf40)
-    irq		- IRQ # for WSS (7,9,10,11)
-    dma1	- DMA # for WSS playback (0,1,3)
-    dma2	- DMA # for WSS capture (0,1), -1 = disabled (default)
-    mpu_port	- port # for MPU-401 UART (0x300,0x330), -1 = disabled (default)
-    mpu_irq	- IRQ # for MPU-401 UART (3,5,7,9), -1 = disabled (default)
-    fm_port	- port # for OPL3 (0x388), -1 = disabled (default)
-
-    This module supports multiple cards. It does not support autoprobe: port,
-    wss_port, irq and dma1 have to be specified. The other values are
-    optional.
-
-    "port" needs to match the BASE ADDRESS jumper on the card (0x220 or 0x240)
-    or the value stored in the card's EEPROM for cards that have an EEPROM and
-    their "CONFIG MODE" jumper set to "EEPROM SETTING". The other values can
-    be chosen freely from the options enumerated above.
-
-    If dma2 is specified and different from dma1, the card will operate in
-    full-duplex mode. When dma1=3, only dma2=0 is valid and the only way to

-    fm_port	- port # for OPL3 (0x388), -1 = disabled (default)
-
-    This module supports multiple cards. It does not support autoprobe: port,
-    wss_port, irq and dma1 have to be specified. The other values are
-    optional.
-
-    "port" needs to match the BASE ADDRESS jumper on the card (0x220 or 0x240)
-    or the value stored in the card's EEPROM for cards that have an EEPROM and
-    their "CONFIG MODE" jumper set to "EEPROM SETTING". The other values can
-    be chosen freely from the options enumerated above.
-
-    If dma2 is specified and different from dma1, the card will operate in
-    full-duplex mode. When dma1=3, only dma2=0 is valid and the only way to
-    enable capture since only channels 0 and 1 are available for capture.
-
-    Generic settings are "port=0x220 wss_port=0x530 irq=10 dma1=1 dma2=0
-    mpu_port=0x330 mpu_irq=9 fm_port=0x388".

-		  0 = auto: falls back to LPIB when POSBUF doesn't work
-		  1 = use LPIB
-		  2 = POSBUF: use position buffer
-		  3 = VIACOMBO: VIA-specific workaround for capture
-		  4 = COMBO: use LPIB for playback, auto for capture stream
-    probe_mask  - Bitmask to probe codecs (default = -1, meaning all slots)
-    		  When the bit 8 (0x100) is set, the lower 8 bits are used
-		  as the "fixed" codec slots; i.e. the driver probes the

-    probe_only	- Only probing and no codec initialization (default=off);
-		  Useful to check the initial codec status for debugging
-    bdl_pos_adj	- Specifies the DMA IRQ timing delay in samples.
-		Passing -1 will make the driver to choose the appropriate
-		value based on the controller chip.
-    patch	- Specifies the early "patch" files to modify the HD-audio
-    		setup before initializing the codecs.  This option is
-		available only when CONFIG_SND_HDA_PATCH_LOADER=y is set.
-		See HD-Audio.txt for details.

-		(default = on)
-    align_buffer_size - Force rounding of buffer/period sizes to multiples
-    		      of 128 bytes. This is more efficient in terms of memory
-		      access but isn't required by the HDA spec and prevents
-		      users from specifying exact period/buffer sizes.

-
-    This module supports multiple cards and autoprobe.
-    
-    See Documentation/sound/alsa/HD-Audio.txt for more details about
-    HD-audio driver.
-
-    Each codec may have a model table for different configurations.
-    If your machine isn't listed there, the default (usually minimal)
-    configuration is set up.  You can pass "model=<name>" option to
-    specify a certain model in such a case.  There are different
-    models depending on the codec chip.  The list of available models
-    is found in HD-Audio-Models.txt
-
-    The model name "generic" is treated as a special case.  When this
-    model is given, the driver uses the generic codec parser without
-    "codec-patch".  It's sometimes good for testing and debugging.
-
-    If the default configuration doesn't work and one of the above
-    matches with your device, report it together with alsa-info.sh
-    output (with --no-upload option) to kernel bugzilla or alsa-devel
-    ML (see the section "Links and Addresses").
-
-    power_save and power_save_controller options are for power-saving
-    mode.  See powersave.txt for details.
-
-    Note 2: If you get click noises on output, try the module option
-	    position_fix=1 or 2.  position_fix=1 will use the SD_LPIB
-	    register value without FIFO size correction as the current
-	    DMA pointer.  position_fix=2 will make the driver to use
-	    the position buffer instead of reading SD_LPIB register.
-	    (Usually SD_LPIB register is more accurate than the
-	    position buffer.)
-
-	    position_fix=3 is specific to VIA devices.  The position
-	    of the capture stream is checked from both LPIB and POSBUF
-	    values.  position_fix=4 is a combination mode, using LPIB
-	    for playback and POSBUF for capture.
-
-    NB: If you get many "azx_get_response timeout" messages at
-    loading, it's likely a problem of interrupts (e.g. ACPI irq
-    routing).  Try to boot with options like "pci=noacpi".  Also, you
-    can try "single_cmd=1" module option.  This will switch the
-    communication method between HDA controller and codecs to the
-    single immediate commands instead of CORB/RIRB.  Basically, the
-    single command mode is provided only for BIOS, and you won't get
-    unsolicited events, too.  But, at least, this works independently
-    from the irq.  Remember this is a last resort, and should be
-    avoided as much as possible...
-    
-    MORE NOTES ON "azx_get_response timeout" PROBLEMS:
-    On some hardware, you may need to add a proper probe_mask option
-    to avoid the "azx_get_response timeout" problem above, instead.
-    This occurs when the access to non-existing or non-working codec slot
-    (likely a modem one) causes a stall of the communication via HD-audio
-    bus.  You can see which codec slots are probed by enabling
-    CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec
-    proc files.  Then limit the slots to probe by probe_mask option.
-    For example, probe_mask=1 means to probe only the first slot, and
-    probe_mask=4 means only the third slot.
-
-    The power-management is supported.

-    hwports	- number of supported hardware ports, default=8.
-    
-    Module supports only 1 card.  This module has no enable option.
-
-  Module snd-mts64
-  ----------------
-
-    Module for Ego Systems (ESI) Miditerminal 4140
-
-    This module supports multiple devices.
-    Requires parport (CONFIG_PARPORT).
-
-  Module snd-nm256
-  ----------------
-
-    Module for NeoMagic NM256AV/ZX chips
-
-    playback_bufsize - max playback frame size in kB (4-128kB)
-    capture_bufsize  - max capture frame size in kB (4-128kB)
-    force_ac97       - 0 or 1 (disabled by default)
-    buffer_top       - specify buffer top address
-    use_cache        - 0 or 1 (disabled by default)
-    vaio_hack        - alias buffer_top=0x25a800
-    reset_workaround - enable AC97 RESET workaround for some laptops
-    reset_workaround2 - enable extended AC97 RESET workaround for some
-		      other laptops
-
-    This module supports one chip and autoprobe.
-
-    The power-management is supported.
-
-    Note: on some notebooks the buffer address cannot be detected
-    automatically, or causes hang-up during initialization.
-    In such a case, specify the buffer top address explicitly via
-    the buffer_top option.
-    For example,
-      Sony F250: buffer_top=0x25a800
-      Sony F270: buffer_top=0x272800
-    The driver supports only ac97 codec.  It's possible to force
-    to initialize/use ac97 although it's not detected.  In such a
-    case, use force_ac97=1 option - but *NO* guarantee whether it
-    works!
-
-    Note: The NM256 chip can be linked internally with non-AC97
-    codecs.  This driver supports only the AC97 codec, and won't work
-    with machines with other (most likely CS423x or OPL3SAx) chips,
-    even though the device is detected in lspci.  In such a case, try
-    other drivers, e.g. snd-cs4232 or snd-opl3sa2.  Some has ISA-PnP
-    but some doesn't have ISA PnP.  You'll need to specify isapnp=0
-    and proper hardware parameters in the case without ISA PnP.
-
-    Note: some laptops need a workaround for AC97 RESET.  For the
-    known hardware like Dell Latitude LS and Sony PCG-F305, this
-    workaround is enabled automatically.  For other laptops with a
-    hard freeze, you can try reset_workaround=1 option.
-
-    Note: Dell Latitude CSx laptops have another problem regarding
-    AC97 RESET.  On these laptops, reset_workaround2 option is
-    turned on as default.  This option is worth to try if the
-    previous reset_workaround option doesn't help.
-
-    Note: This driver is really crappy.  It's a porting from the
-    OSS driver, which is a result of black-magic reverse engineering.
-    The detection of codec will fail if the driver is loaded *after*
-    X-server as described above.  You might be able to force to load
-    the module, but it may result in hang-up.   Hence, make sure that
-    you load this module *before* X if you encounter this kind of
-    problem.

-
-    The below are options for wavefront_synth features:
-    wf_raw	    - Assume that we need to boot the OS (default:no)
-	If yes, then during driver loading, the state of the board is
-	ignored, and we reset the board and load the firmware anyway.
-    fx_raw	    - Assume that the FX process needs help (default:yes)
-	If false, we'll leave the FX processor in whatever state it is
-	when the driver is loaded.  The default is to download the
-	microprogram and associated coefficients to set it up for
-	"default" operation, whatever that means.
-    debug_default   - Debug parameters for card initialization
-    wait_usecs	    - How long to wait without sleeping, usecs
-		      (default:150)
-	This magic number seems to give pretty optimal throughput
-	based on my limited experimentation. 
-	If you want to play around with it and find a better value, be
-	my guest. Remember, the idea is to get a number that causes us
-	to just busy wait for as many WaveFront commands as possible,
-	without coming up with a number so large that we hog the whole
-	CPU. 
-	Specifically, with this number, out of about 134,000 status
-	waits, only about 250 result in a sleep. 
-    sleep_interval  - How long to sleep when waiting for reply
-		      (default: 100)
-    sleep_tries	    - How many times to try sleeping during a wait
-		      (default: 50)
-    ospath	    - Pathname to processed ICS2115 OS firmware
-		      (default:wavefront.os)
-	The path name of the ISC2115 OS firmware.  In the recent
-	version, it's handled via firmware loader framework, so it
-	must be installed in the proper path, typically,
-	/lib/firmware.
-    reset_time	    - How long to wait for a reset to take effect
-		      (default:2)
-    ramcheck_time   - How many seconds to wait for the RAM test
-		      (default:20)
-    osrun_time	    - How many seconds to wait for the ICS2115 OS
-		      (default:10)
-
-    This module supports multiple cards and ISA PnP.
-
-    Note: the firmware file "wavefront.os" was located in the earlier
-          version in /etc.  Now it's loaded via firmware loader, and
-	  must be in the proper firmware path, such as /lib/firmware.
-	  Copy (or symlink) the file appropriately if you get an error
-	  regarding firmware downloading after upgrading the kernel.

-    Module for Tascam USB US-122, US-224 and US-428 devices.
-
-    This module supports multiple devices, autoprobe and hotplugging.
-
-    Note: you need to load the firmware via usx2yloader utility included
-          in alsa-tools and alsa-firmware packages.
-
-  Module snd-via82xx
-  ------------------
-
-    Module for AC'97 motherboards based on VIA 82C686A/686B, 8233,
-    8233A, 8233C, 8235, 8237 (south) bridge.
-
-    mpu_port	- 0x300,0x310,0x320,0x330, otherwise obtain BIOS setup
-		  [VIA686A/686B only]
-    joystick	- Enable joystick (default off) [VIA686A/686B only]
-    ac97_clock	- AC'97 codec clock base (default 48000Hz)
-    dxs_support	- support DXS channels,
-		  0 = auto (default), 1 = enable, 2 = disable,
-		  3 = 48k only, 4 = no VRA, 5 = enable any sample
-		  rate and different sample rates on different
-		  channels
-		  [VIA8233/C, 8235, 8237 only]
-    ac97_quirk  - AC'97 workaround for strange hardware
-		  See "AC97 Quirk Option" section below.
-
-    This module supports one chip and autoprobe.
-
-    Note: on some SMP motherboards like MSI 694D the interrupts might
-          not be generated properly.  In such a case, please try to
-          set the SMP (or MPS) version on BIOS to 1.1 instead of
-          default value 1.4.  Then the interrupt number will be
-          assigned under 15. You might also upgrade your BIOS.
-    
-    Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
-	  channels as the first PCM.  On these channels, up to 4
-	  streams can be played at the same time, and the controller
-	  can perform sample rate conversion with separate rates for
-	  each channel.
-	  As default (dxs_support = 0), 48k fixed rate is chosen
-	  except for the known devices since the output is often
-	  noisy except for 48k on some mother boards due to the
-	  bug of BIOS.
-	  Please try once dxs_support=5 and if it works on other
-	  sample rates (e.g. 44.1kHz of mp3 playback), please let us
-	  know the PCI subsystem vendor/device id's (output of
-	  "lspci -nv").
-	  If dxs_support=5 does not work, try dxs_support=4; if it
-	  doesn't work too, try dxs_support=1.  (dxs_support=1 is
-	  usually for old motherboards.  The correct implemented
-	  board should work with 4 or 5.)  If it still doesn't
-	  work and the default setting is ok, dxs_support=3 is the
-	  right choice.  If the default setting doesn't work at all,
-	  try dxs_support=2 to disable the DXS channels.
-	  In any cases, please let us know the result and the
-	  subsystem vendor/device ids.  See "Links and Addresses"
-	  below.
-
-    Note: for the MPU401 on VIA823x, use snd-mpu401 driver
-	  additionally.  The mpu_port option is for VIA686 chips only.
-
-    The power-management is supported.
-
-  Module snd-via82xx-modem
-  ------------------------
-
-    Module for VIA82xx AC97 modem
-

-
-    This module supports one card and autoprobe.
-
-    Note: The default index value of this module is -2, i.e. the first
-          slot is excluded.
-
-    The power-management is supported.
-
-  Module snd-virmidi
-  ------------------
-
-    Module for virtual rawmidi devices.
-    This module creates virtual rawmidi devices which communicate
-    to the corresponding ALSA sequencer ports.

-
-  Module snd-virtuoso
-  -------------------
-
-    Module for sound cards based on the Asus AV66/AV100/AV200 chips,
-    i.e., Xonar D1, DX, D2, D2X, DS, DSX, Essence ST (Deluxe),
-    Essence STX (II), HDAV1.3 (Deluxe), and HDAV1.3 Slim.
-
-    This module supports autoprobe and multiple cards.
-
-  Module snd-vx222
-  ----------------
-
-    Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards.
-
-    mic		- Enable Microphone on V222 Mic (NYI)
-    ibl		- Capture IBL size. (default = 0, minimum size)
-
-    This module supports multiple cards.
-
-    When the driver is compiled as a module and the hotplug firmware
-    is supported, the firmware data is loaded via hotplug automatically.
-    Install the necessary firmware files in alsa-firmware package.
-    When no hotplug fw loader is available, you need to load the
-    firmware via vxloader utility in alsa-tools package.  To invoke
-    vxloader automatically, add the following to /etc/modprobe.d/alsa.conf
-
-	install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
-
-    (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
-     /etc/modules.conf, instead.)
-    IBL size defines the interrupts period for PCM.  The smaller size
-    gives smaller latency but leads to more CPU consumption, too.
-    The size is usually aligned to 126.  As default (=0), the smallest
-    size is chosen.  The possible IBL values can be found in
-    /proc/asound/cardX/vx-status proc file.
-
-    The power-management is supported.
-
-  Module snd-vxpocket
-  -------------------
-
-    Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
-
-    ibl      - Capture IBL size. (default = 0, minimum size)
-
-    This module supports multiple cards.  The module is compiled only when
-    PCMCIA is supported on kernel.
-
-    With the older 2.6.x kernel, to activate the driver via the card
-    manager, you'll need to set up /etc/pcmcia/vxpocket.conf.  See the
-    sound/pcmcia/vx/vxpocket.c.  2.6.13 or later kernel requires no
-    longer require a config file.
-
-    When the driver is compiled as a module and the hotplug firmware
-    is supported, the firmware data is loaded via hotplug automatically.
-    Install the necessary firmware files in alsa-firmware package.
-    When no hotplug fw loader is available, you need to load the
-    firmware via vxloader utility in alsa-tools package.
-
-    About capture IBL, see the description of snd-vx222 module.
-
-    Note: snd-vxp440 driver is merged to snd-vxpocket driver since
-           ALSA 1.0.10.
-
-    The power-management is supported.

-AC97 Quirk Option
-=================
-
-The ac97_quirk option is used to enable/override the workaround for
-specific devices on drivers for on-board AC'97 controllers like
-snd-intel8x0.  Some hardware have swapped output pins between Master
-and Headphone, or Surround (thanks to confusion of AC'97
-specifications from version to version :-)
-
-The driver provides the auto-detection of known problematic devices,
-but some might be unknown or wrongly detected.  In such a case, pass
-the proper value with this option.
-
-The following strings are accepted:
-    - default	Don't override the default setting
-    - none	Disable the quirk
-    - hp_only	Bind Master and Headphone controls as a single control
-    - swap_hp	Swap headphone and master controls
-    - swap_surround  Swap master and surround controls
-    - ad_sharing  For AD1985, turn on OMS bit and use headphone
-    - alc_jack	For ALC65x, turn on the jack sense mode
-    - inv_eapd	Inverted EAPD implementation
-    - mute_led	Bind EAPD bit for turning on/off mute LED
-
-For backward compatibility, the corresponding integer value -1, 0,
-... are  accepted, too.
-
-For example, if "Master" volume control has no effect on your device
-but only "Headphone" does, pass ac97_quirk=hp_only module option.
-
-
-Configuring Non-ISAPNP Cards
-============================
-
-When the kernel is configured with ISA-PnP support, the modules
-supporting the isapnp cards will have module options "isapnp".
-If this option is set, *only* the ISA-PnP devices will be probed.
-For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
-together with the proper i/o and irq configuration.
-
-When the kernel is configured without ISA-PnP support, isapnp option
-will be not built in.
-
-
-Module Autoloading Support
-==========================
-
-The ALSA drivers can be loaded automatically on demand by defining
-module aliases.  The string 'snd-card-%1' is requested for ALSA native
-devices where %i is sound card number from zero to seven.
-
-To auto-load an ALSA driver for OSS services, define the string
-'sound-slot-%i' where %i means the slot number for OSS, which
-corresponds to the card index of ALSA.  Usually, define this
-as the same card module.
-
-An example configuration for a single emu10k1 card is like below:
------ /etc/modprobe.d/alsa.conf
-alias snd-card-0 snd-emu10k1
-alias sound-slot-0 snd-emu10k1
------ /etc/modprobe.d/alsa.conf
-
-The available number of auto-loaded sound cards depends on the module
-option "cards_limit" of snd module.  As default it's set to 1.
-To enable the auto-loading of multiple cards, specify the number of
-sound cards in that option.
-
-When multiple cards are available, it'd better to specify the index
-number for each card via module option, too, so that the order of
-cards is kept consistent.
-
-An example configuration for two sound cards is like below:
-
------ /etc/modprobe.d/alsa.conf
-# ALSA portion
-options snd cards_limit=2
-alias snd-card-0 snd-interwave
-alias snd-card-1 snd-ens1371
-options snd-interwave index=0
-options snd-ens1371 index=1
-# OSS/Free portion
-alias sound-slot-0 snd-interwave
-alias sound-slot-1 snd-ens1371
------ /etc/modprobe.d/alsa.conf
-
-In this example, the interwave card is always loaded as the first card
-(index 0) and ens1371 as the second (index 1).
-
-Alternative (and new) way to fixate the slot assignment is to use
-"slots" option of snd module.  In the case above, specify like the
-following: 
-
-options snd slots=snd-interwave,snd-ens1371
-
-Then, the first slot (#0) is reserved for snd-interwave driver, and
-the second (#1) for snd-ens1371.  You can omit index option in each
-driver if slots option is used (although you can still have them at
-the same time as long as they don't conflict).
-
-The slots option is especially useful for avoiding the possible
-hot-plugging and the resultant slot conflict.  For example, in the
-case above again, the first two slots are already reserved.  If any
-other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
-snd-ens1371, it will be assigned to the third or later slot.
-
-When a module name is given with '!', the slot will be given for any
-modules but that name.  For example, "slots=!snd-pcsp" will reserve
-the first slot for any modules but snd-pcsp. 
-
-
-ALSA PCM devices to OSS devices mapping
-=======================================
-
-/dev/snd/pcmC0D0[c|p]  -> /dev/audio0 (/dev/audio) -> minor 4
-/dev/snd/pcmC0D0[c|p]  -> /dev/dsp0 (/dev/dsp)     -> minor 3
-/dev/snd/pcmC0D1[c|p]  -> /dev/adsp0 (/dev/adsp)   -> minor 12
-/dev/snd/pcmC1D0[c|p]  -> /dev/audio1              -> minor 4+16 = 20
-/dev/snd/pcmC1D0[c|p]  -> /dev/dsp1                -> minor 3+16 = 19
-/dev/snd/pcmC1D1[c|p]  -> /dev/adsp1               -> minor 12+16 = 28
-/dev/snd/pcmC2D0[c|p]  -> /dev/audio2              -> minor 4+32 = 36
-/dev/snd/pcmC2D0[c|p]  -> /dev/dsp2                -> minor 3+32 = 39
-/dev/snd/pcmC2D1[c|p]  -> /dev/adsp2               -> minor 12+32 = 44
-
-The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
-sound card number and second means device number.  The ALSA devices
-have either 'c' or 'p' suffix indicating the direction, capture and
-playback, respectively.
-
-Please note that the device mapping above may be varied via the module
-options of snd-pcm-oss module.
-
-
-Proc interfaces (/proc/asound)
-==============================
-
-/proc/asound/card#/pcm#[cp]/oss
--------------------------------
-  String "erase" - erase all additional information about OSS applications
-  String "<app_name> <fragments> <fragment_size> [<options>]"
-
-   <app_name> - name of application with (higher priority) or without path
-   <fragments> - number of fragments or zero if auto
-   <fragment_size> - size of fragment in bytes or zero if auto
-   <options> - optional parameters
-	  - disable   the application tries to open a pcm device for
-		      this channel but does not want to use it.
-		      (Cause a bug or mmap needs)
-		      It's good for Quake etc...
-	  - direct    don't use plugins
-	  - block     force block mode (rvplayer)
-	  - non-block force non-block mode
-	  - whole-frag  write only whole fragments (optimization affecting
-			playback only)
-	  - no-silence  do not fill silence ahead to avoid clicks
-	  - buggy-ptr	Returns the whitespace blocks in GETOPTR ioctl
-			instead of filled blocks
-
-  Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
-           echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
-	   echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
-
-
-Early Buffer Allocation
-=======================
-
-Some drivers (e.g. hdsp) require the large contiguous buffers, and
-sometimes it's too late to find such spaces when the driver module is
-actually loaded due to memory fragmentation.  You can pre-allocate the
-PCM buffers by loading snd-page-alloc module and write commands to its
-proc file in prior, for example, in the early boot stage like
-/etc/init.d/*.local scripts.
-
-Reading the proc file /proc/drivers/snd-page-alloc shows the current
-usage of page allocation.  In writing, you can send the following
-commands to the snd-page-alloc driver:
-
-  - add VENDOR DEVICE MASK SIZE BUFFERS
-
-    VENDOR and DEVICE are PCI vendor and device IDs.  They take
-    integer numbers (0x prefix is needed for the hex).
-    MASK is the PCI DMA mask.  Pass 0 if not restricted.
-    SIZE is the size of each buffer to allocate.  You can pass
-    k and m suffix for KB and MB.  The max number is 16MB.
-    BUFFERS is the number of buffers to allocate.  It must be greater
-    than 0.  The max number is 4.
-
-  - erase
-
-    This will erase the all pre-allocated buffers which are not in
-    use.

-<P>ver.0.1.8; Nov. 16, 1999
-<H2>
-
-<HR WIDTH="100%"></H2>
-
-<H2>
-1. Description</H2>
-This directory contains the OSS sequencer emulation driver on ALSA. Note
-that this program is still in the development state.
-<P>What this does - it provides the emulation of the OSS sequencer, access
-via
-<TT>/dev/sequencer</TT> and <TT>/dev/music</TT> devices.
-The most of applications using OSS can run if the appropriate ALSA
-sequencer is prepared.
-<P>The following features are emulated by this driver:
-<UL>
-<LI>
-Normal sequencer and MIDI events:</LI>
-
-<BR>They are converted to the ALSA sequencer events, and sent to the corresponding
-port.
-<LI>
-Timer events:</LI>
-
-<BR>The timer is not selectable by ioctl. The control rate is fixed to
-100 regardless of HZ. That is, even on Alpha system, a tick is always
-1/100 second. The base rate and tempo can be changed in <TT>/dev/music</TT>.
-
-<LI>
-Patch loading:</LI>
-
-<BR>It purely depends on the synth drivers whether it's supported since
-the patch loading is realized by callback to the synth driver.
-<LI>
-I/O controls:</LI>
-
-<BR>Most of controls are accepted. Some controls
-are dependent on the synth driver, as well as even on original OSS.</UL>
-Furthermore, you can find the following advanced features:
-<UL>
-<LI>
-Better queue mechanism:</LI>
-
-<BR>The events are queued before processing them.
-<LI>
-Multiple applications:</LI>
-
-<BR>You can run two or more applications simultaneously (even for OSS sequencer)!
-However, each MIDI device is exclusive - that is, if a MIDI device is opened
-once by some application, other applications can't use it. No such a restriction
-in synth devices.
-<LI>
-Real-time event processing:</LI>
-
-<BR>The events can be processed in real time without using out of bound
-ioctl. To switch to real-time mode, send ABSTIME 0 event. The followed
-events will be processed in real-time without queued. To switch off the
-real-time mode, send RELTIME 0 event.
-<LI>
-<TT>/proc</TT> interface:</LI>
-
-<BR>The status of applications and devices can be shown via <TT>/proc/asound/seq/oss</TT>
-at any time. In the later version, configuration will be changed via <TT>/proc</TT>
-interface, too.</UL>
-
-<H2>
-2. Installation</H2>
-Run configure script with both sequencer support (<TT>--with-sequencer=yes</TT>)
-and OSS emulation (<TT>--with-oss=yes</TT>) options. A module <TT>snd-seq-oss.o</TT>
-will be created. If the synth module of your sound card supports for OSS
-emulation (so far, only Emu8000 driver), this module will be loaded automatically.
-Otherwise, you need to load this module manually.
-<P>At beginning, this module probes all the MIDI ports which have been
-already connected to the sequencer. Once after that, the creation and deletion
-of ports are watched by announcement mechanism of ALSA sequencer.
-<P>The available synth and MIDI devices can be found in proc interface.
-Run "<TT>cat /proc/asound/seq/oss</TT>", and check the devices. For example,
-if you use an AWE64 card, you'll see like the following:
-<PRE>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; OSS sequencer emulation version 0.1.8
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ALSA client number 63
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ALSA receiver port 0
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Number of applications: 0
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Number of synth devices: 1
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; synth 0: [EMU8000]
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; type 0x1 : subtype 0x20 : voices 32
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; capabilties : ioctl enabled / load_patch enabled
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Number of MIDI devices: 3
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; midi 0: [Emu8000 Port-0] ALSA port 65:0
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; capability write / opened none
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; midi 1: [Emu8000 Port-1] ALSA port 65:1
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; capability write / opened none
-
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; midi 2: [0: MPU-401 (UART)] ALSA port 64:0
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; capability read/write / opened none</PRE>
-Note that the device number may be different from the information of
-<TT>/proc/asound/oss-devices</TT>
-or ones of the original OSS driver. Use the device number listed in <TT>/proc/asound/seq/oss</TT>
-to play via OSS sequencer emulation.
-<H2>
-3. Using Synthesizer Devices</H2>
-Run your favorite program. I've tested playmidi-2.4, awemidi-0.4.3, gmod-3.1
-and xmp-1.1.5. You can load samples via <TT>/dev/sequencer</TT> like sfxload,
-too.
-<P>If the lowlevel driver supports multiple access to synth devices (like
-Emu8000 driver), two or more applications are allowed to run at the same
-time.
-<H2>
-4. Using MIDI Devices</H2>
-So far, only MIDI output was tested. MIDI input was not checked at all,
-but hopefully it will work. Use the device number listed in <TT>/proc/asound/seq/oss</TT>.
-Be aware that these numbers are mostly different from the list in
-<TT>/proc/asound/oss-devices</TT>.
-<H2>
-5. Module Options</H2>
-The following module options are available:
-<UL>
-<LI>
-<TT>maxqlen</TT></LI>
-
-<BR>specifies the maximum read/write queue length. This queue is private
-for OSS sequencer, so that it is independent from the queue length of ALSA
-sequencer. Default value is 1024.
-<LI>
-<TT>seq_oss_debug</TT></LI>
-
-<BR>specifies the debug level and accepts zero (= no debug message) or
-positive integer. Default value is 0.</UL>
-
-<H2>
-6. Queue Mechanism</H2>
-OSS sequencer emulation uses an ALSA priority queue. The
-events from <TT>/dev/sequencer</TT> are processed and put onto the queue
-specified by module option.
-<P>All the events from <TT>/dev/sequencer</TT> are parsed at beginning.
-The timing events are also parsed at this moment, so that the events may
-be processed in real-time. Sending an event ABSTIME 0 switches the operation
-mode to real-time mode, and sending an event RELTIME 0 switches it off.
-In the real-time mode, all events are dispatched immediately.
-<P>The queued events are dispatched to the corresponding ALSA sequencer
-ports after scheduled time by ALSA sequencer dispatcher.
-<P>If the write-queue is full, the application sleeps until a certain amount
-(as default one half) becomes empty in blocking mode. The synchronization
-to write timing was implemented, too.
-<P>The input from MIDI devices or echo-back events are stored on read FIFO
-queue. If application reads <TT>/dev/sequencer</TT> in blocking mode, the
-process will be awaked.
-
-<H2>
-7. Interface to Synthesizer Device</H2>
-
-<H3>
-7.1. Registration</H3>
-To register an OSS synthesizer device, use <TT>snd_seq_oss_synth_register</TT>
-function.
-<PRE>int snd_seq_oss_synth_register(char *name, int type, int subtype, int nvoices,
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; snd_seq_oss_callback_t *oper, void *private_data)</PRE>
-The arguments <TT>name</TT>, <TT>type</TT>, <TT>subtype</TT> and
-<TT>nvoices</TT>
-are used for making the appropriate synth_info structure for ioctl. The
-return value is an index number of this device. This index must be remembered
-for unregister. If registration is failed, -errno will be returned.
-<P>To release this device, call <TT>snd_seq_oss_synth_unregister function</TT>:
-<PRE>int snd_seq_oss_synth_unregister(int index),</PRE>
-where the <TT>index</TT> is the index number returned by register function.
-<H3>
-7.2. Callbacks</H3>
-OSS synthesizer devices have capability for sample downloading and ioctls
-like sample reset. In OSS emulation, these special features are realized
-by using callbacks. The registration argument oper is used to specify these
-callbacks. The following callback functions must be defined:
-<PRE>snd_seq_oss_callback_t:
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int (*open)(snd_seq_oss_arg_t *p, void *closure);
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int (*close)(snd_seq_oss_arg_t *p);
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int (*ioctl)(snd_seq_oss_arg_t *p, unsigned int cmd, unsigned long arg);
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int (*load_patch)(snd_seq_oss_arg_t *p, int format, const char *buf, int offs, int count);
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int (*reset)(snd_seq_oss_arg_t *p);
-Except for <TT>open</TT> and <TT>close</TT> callbacks, they are allowed
-to be NULL.
-<P>Each callback function takes the argument type snd_seq_oss_arg_t as the
-first argument.
-<PRE>struct snd_seq_oss_arg_t {
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int app_index;
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int file_mode;
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int seq_mode;
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; snd_seq_addr_t addr;
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; void *private_data;
-&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int event_passing;
-};</PRE>
-The first three fields, <TT>app_index</TT>, <TT>file_mode</TT> and
-<TT>seq_mode</TT>
-are initialized by OSS sequencer. The <TT>app_index</TT> is the application
-index which is unique to each application opening OSS sequencer. The
-<TT>file_mode</TT>
-is bit-flags indicating the file operation mode. See
-<TT>seq_oss.h</TT>
-for its meaning. The <TT>seq_mode</TT> is sequencer operation mode. In
-the current version, only <TT>SND_OSSSEQ_MODE_SYNTH</TT> is used.
-<P>The next two fields, <TT>addr</TT> and <TT>private_data</TT>, must be
-filled by the synth driver at open callback. The <TT>addr</TT> contains
-the address of ALSA sequencer port which is assigned to this device. If
-the driver allocates memory for <TT>private_data</TT>, it must be released
-in close callback by itself.
-<P>The last field, <TT>event_passing</TT>, indicates how to translate note-on
-/ off events. In <TT>PROCESS_EVENTS</TT> mode, the note 255 is regarded
-as velocity change, and key pressure event is passed to the port. In <TT>PASS_EVENTS</TT>
-mode, all note on/off events are passed to the port without modified. <TT>PROCESS_KEYPRESS</TT>
-mode checks the note above 128 and regards it as key pressure event (mainly
-for Emu8000 driver).
-<H4>
-7.2.1. Open Callback</H4>
-The <TT>open</TT> is called at each time this device is opened by an application
-using OSS sequencer. This must not be NULL. Typically, the open callback
-does the following procedure:
-<OL>
-<LI>
-Allocate private data record.</LI>
-
-<LI>
-Create an ALSA sequencer port.</LI>
-
-<LI>
-Set the new port address on arg->addr.</LI>
-
-<LI>
-Set the private data record pointer on arg->private_data.</LI>
-</OL>
-Note that the type bit-flags in port_info of this synth port must NOT contain
-<TT>TYPE_MIDI_GENERIC</TT>
-bit. Instead, <TT>TYPE_SPECIFIC</TT> should be used. Also, <TT>CAP_SUBSCRIPTION</TT>
-bit should NOT be included, too. This is necessary to tell it from other
-normal MIDI devices. If the open procedure succeeded, return zero. Otherwise,
-return -errno.
-<H4>
-7.2.2 Ioctl Callback</H4>
-The <TT>ioctl</TT> callback is called when the sequencer receives device-specific
-ioctls. The following two ioctls should be processed by this callback:
-<UL>
-<LI>
-<TT>IOCTL_SEQ_RESET_SAMPLES</TT></LI>
-
-<BR>reset all samples on memory -- return 0
-<LI>
-<TT>IOCTL_SYNTH_MEMAVL</TT></LI>
-
-<BR>return the available memory size
-<LI>
-<TT>FM_4OP_ENABLE</TT></LI>
-
-<BR>can be ignored usually</UL>
-The other ioctls are processed inside the sequencer without passing to
-the lowlevel driver.
-<H4>
-7.2.3 Load_Patch Callback</H4>
-The <TT>load_patch</TT> callback is used for sample-downloading. This callback
-must read the data on user-space and transfer to each device. Return 0
-if succeeded, and -errno if failed. The format argument is the patch key
-in patch_info record. The buf is user-space pointer where patch_info record
-is stored. The offs can be ignored. The count is total data size of this
-sample data.
-<H4>
-7.2.4 Close Callback</H4>
-The <TT>close</TT> callback is called when this device is closed by the
-application. If any private data was allocated in open callback, it must
-be released in the close callback. The deletion of ALSA port should be
-done here, too. This callback must not be NULL.
-<H4>
-7.2.5 Reset Callback</H4>
-The <TT>reset</TT> callback is called when sequencer device is reset or
-closed by applications. The callback should turn off the sounds on the
-relevant port immediately, and initialize the status of the port. If this
-callback is undefined, OSS seq sends a <TT>HEARTBEAT</TT> event to the
-port.
-<H3>
-7.3 Events</H3>
-Most of the events are processed by sequencer and translated to the adequate
-ALSA sequencer events, so that each synth device can receive by input_event
-callback of ALSA sequencer port. The following ALSA events should be implemented
-by the driver:

-<P>The most of these behavior can be realized by MIDI emulation driver
-included in the Emu8000 lowlevel driver. In the future release, this module
-will be independent.
-<P>Some OSS events (<TT>SEQ_PRIVATE</TT> and <TT>SEQ_VOLUME</TT> events) are passed as event
-type SND_SEQ_OSS_PRIVATE.  The OSS sequencer passes these event 8 byte
-packets without any modification. The lowlevel driver should process these
-events appropriately.
-<H2>
-8. Interface to MIDI Device</H2>
-Since the OSS emulation probes the creation and deletion of ALSA MIDI sequencer
-ports automatically by receiving announcement from ALSA sequencer, the
-MIDI devices don't need to be registered explicitly like synth devices.
-However, the MIDI port_info registered to ALSA sequencer must include a group
-name <TT>SND_SEQ_GROUP_DEVICE</TT> and a capability-bit <TT>CAP_READ</TT> or
-<TT>CAP_WRITE</TT>. Also, subscription capabilities, <TT>CAP_SUBS_READ</TT> or <TT>CAP_SUBS_WRITE</TT>,
-must be defined, too. If these conditions are not satisfied, the port is not
-registered as OSS sequencer MIDI device.
-<P>The events via MIDI devices are parsed in OSS sequencer and converted
-to the corresponding ALSA sequencer events. The input from MIDI sequencer
-is also converted to MIDI byte events by OSS sequencer. This works just
-a reverse way of seq_midi module.

+===============================
+OSS Sequencer Emulation on ALSA
+===============================
+
+Copyright (c) 1998,1999 by Takashi Iwai
+
+ver.0.1.8; Nov. 16, 1999
+
+Description
+===========
+
+This directory contains the OSS sequencer emulation driver on ALSA. Note
+that this program is still in the development state.
+
+What this does - it provides the emulation of the OSS sequencer, access
+via ``/dev/sequencer`` and ``/dev/music`` devices.
+The most of applications using OSS can run if the appropriate ALSA
+sequencer is prepared.
+
+The following features are emulated by this driver:
+
+* Normal sequencer and MIDI events:
+
+    They are converted to the ALSA sequencer events, and sent to the
+    corresponding port.
+
+* Timer events:
+
+    The timer is not selectable by ioctl. The control rate is fixed to
+    100 regardless of HZ. That is, even on Alpha system, a tick is always
+    1/100 second. The base rate and tempo can be changed in ``/dev/music``.
+
+* Patch loading:
+
+    It purely depends on the synth drivers whether it's supported since
+    the patch loading is realized by callback to the synth driver.
+
+* I/O controls:
+
+    Most of controls are accepted. Some controls
+    are dependent on the synth driver, as well as even on original OSS.
+
+Furthermore, you can find the following advanced features:
+
+* Better queue mechanism:
+
+    The events are queued before processing them.
+
+* Multiple applications:
+
+    You can run two or more applications simultaneously (even for OSS
+    sequencer)!
+    However, each MIDI device is exclusive - that is, if a MIDI device
+    is opened once by some application, other applications can't use
+    it. No such a restriction in synth devices.
+
+* Real-time event processing:
+
+    The events can be processed in real time without using out of bound
+    ioctl. To switch to real-time mode, send ABSTIME 0 event. The followed
+    events will be processed in real-time without queued. To switch off the
+    real-time mode, send RELTIME 0 event.
+
+* ``/proc`` interface:
+
+    The status of applications and devices can be shown via
+    ``/proc/asound/seq/oss`` at any time. In the later version,
+    configuration will be changed via ``/proc`` interface, too.
+
+
+Installation
+============
+
+Run configure script with both sequencer support (``--with-sequencer=yes``)
+and OSS emulation (``--with-oss=yes``) options. A module ``snd-seq-oss.o``
+will be created. If the synth module of your sound card supports for OSS
+emulation (so far, only Emu8000 driver), this module will be loaded
+automatically.
+Otherwise, you need to load this module manually.
+
+At beginning, this module probes all the MIDI ports which have been
+already connected to the sequencer. Once after that, the creation and deletion
+of ports are watched by announcement mechanism of ALSA sequencer.
+
+The available synth and MIDI devices can be found in proc interface.
+Run ``cat /proc/asound/seq/oss``, and check the devices. For example,
+if you use an AWE64 card, you'll see like the following:
+::
+
+    OSS sequencer emulation version 0.1.8
+    ALSA client number 63
+    ALSA receiver port 0
+
+    Number of applications: 0
+
+    Number of synth devices: 1
+    synth 0: [EMU8000]
+      type 0x1 : subtype 0x20 : voices 32
+      capabilties : ioctl enabled / load_patch enabled
+
+    Number of MIDI devices: 3
+    midi 0: [Emu8000 Port-0] ALSA port 65:0
+      capability write / opened none
+
+    midi 1: [Emu8000 Port-1] ALSA port 65:1
+      capability write / opened none
+
+    midi 2: [0: MPU-401 (UART)] ALSA port 64:0
+      capability read/write / opened none
+
+Note that the device number may be different from the information of
+``/proc/asound/oss-devices`` or ones of the original OSS driver.
+Use the device number listed in ``/proc/asound/seq/oss``
+to play via OSS sequencer emulation.
+
+Using Synthesizer Devices
+=========================
+
+Run your favorite program. I've tested playmidi-2.4, awemidi-0.4.3, gmod-3.1
+and xmp-1.1.5. You can load samples via ``/dev/sequencer`` like sfxload,
+too.
+
+If the lowlevel driver supports multiple access to synth devices (like
+Emu8000 driver), two or more applications are allowed to run at the same
+time.
+
+Using MIDI Devices
+==================
+
+So far, only MIDI output was tested. MIDI input was not checked at all,
+but hopefully it will work. Use the device number listed in
+``/proc/asound/seq/oss``.
+Be aware that these numbers are mostly different from the list in
+``/proc/asound/oss-devices``.
+
+Module Options
+==============
+
+The following module options are available:
+
+maxqlen
+  specifies the maximum read/write queue length. This queue is private
+  for OSS sequencer, so that it is independent from the queue length of ALSA
+  sequencer. Default value is 1024.
+
+seq_oss_debug
+  specifies the debug level and accepts zero (= no debug message) or
+  positive integer. Default value is 0.
+
+Queue Mechanism
+===============
+
+OSS sequencer emulation uses an ALSA priority queue. The
+events from ``/dev/sequencer`` are processed and put onto the queue
+specified by module option.
+
+All the events from ``/dev/sequencer`` are parsed at beginning.
+The timing events are also parsed at this moment, so that the events may
+be processed in real-time. Sending an event ABSTIME 0 switches the operation
+mode to real-time mode, and sending an event RELTIME 0 switches it off.
+In the real-time mode, all events are dispatched immediately.
+
+The queued events are dispatched to the corresponding ALSA sequencer
+ports after scheduled time by ALSA sequencer dispatcher.
+
+If the write-queue is full, the application sleeps until a certain amount
+(as default one half) becomes empty in blocking mode. The synchronization
+to write timing was implemented, too.
+
+The input from MIDI devices or echo-back events are stored on read FIFO
+queue. If application reads ``/dev/sequencer`` in blocking mode, the
+process will be awaked.
+
+Interface to Synthesizer Device
+===============================
+
+Registration
+------------
+
+To register an OSS synthesizer device, use snd_seq_oss_synth_register()
+function:
+::
+
+  int snd_seq_oss_synth_register(char *name, int type, int subtype, int nvoices,
+          snd_seq_oss_callback_t *oper, void *private_data)
+
+The arguments ``name``, ``type``, ``subtype`` and ``nvoices``
+are used for making the appropriate synth_info structure for ioctl. The
+return value is an index number of this device. This index must be remembered
+for unregister. If registration is failed, -errno will be returned.
+
+To release this device, call snd_seq_oss_synth_unregister() function:
+::
+
+  int snd_seq_oss_synth_unregister(int index)
+
+where the ``index`` is the index number returned by register function.
+
+Callbacks
+---------
+
+OSS synthesizer devices have capability for sample downloading and ioctls
+like sample reset. In OSS emulation, these special features are realized
+by using callbacks. The registration argument oper is used to specify these
+callbacks. The following callback functions must be defined:
+::
+
+  snd_seq_oss_callback_t:
+   int (*open)(snd_seq_oss_arg_t *p, void *closure);
+   int (*close)(snd_seq_oss_arg_t *p);
+   int (*ioctl)(snd_seq_oss_arg_t *p, unsigned int cmd, unsigned long arg);
+   int (*load_patch)(snd_seq_oss_arg_t *p, int format, const char *buf, int offs, int count);
+   int (*reset)(snd_seq_oss_arg_t *p);
+
+Except for ``open`` and ``close`` callbacks, they are allowed to be NULL.
+
+Each callback function takes the argument type ``snd_seq_oss_arg_t`` as the
+first argument.
+::

+  struct snd_seq_oss_arg_t {
+      int app_index;
+      int file_mode;
+      int seq_mode;
+      snd_seq_addr_t addr;
+      void *private_data;
+      int event_passing;
+  };
+
+The first three fields, ``app_index``, ``file_mode`` and ``seq_mode``
+are initialized by OSS sequencer. The ``app_index`` is the application
+index which is unique to each application opening OSS sequencer. The
+``file_mode`` is bit-flags indicating the file operation mode. See
+``seq_oss.h`` for its meaning. The ``seq_mode`` is sequencer operation
+mode. In the current version, only ``SND_OSSSEQ_MODE_SYNTH`` is used.
+
+The next two fields, ``addr`` and ``private_data``, must be
+filled by the synth driver at open callback. The ``addr`` contains
+the address of ALSA sequencer port which is assigned to this device. If
+the driver allocates memory for ``private_data``, it must be released
+in close callback by itself.
+
+The last field, ``event_passing``, indicates how to translate note-on
+/ off events. In ``PROCESS_EVENTS`` mode, the note 255 is regarded
+as velocity change, and key pressure event is passed to the port. In
+``PASS_EVENTS`` mode, all note on/off events are passed to the port
+without modified. ``PROCESS_KEYPRESS`` mode checks the note above 128
+and regards it as key pressure event (mainly for Emu8000 driver).
+
+Open Callback
+-------------
+
+The ``open`` is called at each time this device is opened by an application
+using OSS sequencer. This must not be NULL. Typically, the open callback
+does the following procedure:
+
+#. Allocate private data record.
+#. Create an ALSA sequencer port.
+#. Set the new port address on ``arg->addr``.
+#. Set the private data record pointer on ``arg->private_data``.
+
+Note that the type bit-flags in port_info of this synth port must NOT contain
+``TYPE_MIDI_GENERIC``
+bit. Instead, ``TYPE_SPECIFIC`` should be used. Also, ``CAP_SUBSCRIPTION``
+bit should NOT be included, too. This is necessary to tell it from other
+normal MIDI devices. If the open procedure succeeded, return zero. Otherwise,
+return -errno.
+
+Ioctl Callback
+--------------
+
+The ``ioctl`` callback is called when the sequencer receives device-specific
+ioctls. The following two ioctls should be processed by this callback:
+
+IOCTL_SEQ_RESET_SAMPLES
+    reset all samples on memory -- return 0
+
+IOCTL_SYNTH_MEMAVL
+    return the available memory size
+
+FM_4OP_ENABLE
+    can be ignored usually
+
+The other ioctls are processed inside the sequencer without passing to
+the lowlevel driver.
+
+Load_Patch Callback
+-------------------
+
+The ``load_patch`` callback is used for sample-downloading. This callback
+must read the data on user-space and transfer to each device. Return 0
+if succeeded, and -errno if failed. The format argument is the patch key
+in patch_info record. The buf is user-space pointer where patch_info record
+is stored. The offs can be ignored. The count is total data size of this
+sample data.
+
+Close Callback
+--------------
+
+The ``close`` callback is called when this device is closed by the
+application. If any private data was allocated in open callback, it must
+be released in the close callback. The deletion of ALSA port should be
+done here, too. This callback must not be NULL.
+
+Reset Callback
+--------------
+
+The ``reset`` callback is called when sequencer device is reset or
+closed by applications. The callback should turn off the sounds on the
+relevant port immediately, and initialize the status of the port. If this
+callback is undefined, OSS seq sends a ``HEARTBEAT`` event to the
+port.
+
+Events
+======
+
+Most of the events are processed by sequencer and translated to the adequate
+ALSA sequencer events, so that each synth device can receive by input_event
+callback of ALSA sequencer port. The following ALSA events should be
+implemented by the driver:
+
+=============	===================
+ALSA event	Original OSS events
+=============	===================
+NOTEON		SEQ_NOTEON, MIDI_NOTEON
+NOTE		SEQ_NOTEOFF, MIDI_NOTEOFF
+KEYPRESS	MIDI_KEY_PRESSURE
+CHANPRESS	SEQ_AFTERTOUCH, MIDI_CHN_PRESSURE
+PGMCHANGE	SEQ_PGMCHANGE, MIDI_PGM_CHANGE
+PITCHBEND	SEQ_CONTROLLER(CTRL_PITCH_BENDER),
+		MIDI_PITCH_BEND
+CONTROLLER	MIDI_CTL_CHANGE,
+		SEQ_BALANCE (with CTL_PAN)
+CONTROL14	SEQ_CONTROLLER
+REGPARAM	SEQ_CONTROLLER(CTRL_PITCH_BENDER_RANGE)
+SYSEX		SEQ_SYSEX
+=============	===================
+
+The most of these behavior can be realized by MIDI emulation driver
+included in the Emu8000 lowlevel driver. In the future release, this module
+will be independent.
+
+Some OSS events (``SEQ_PRIVATE`` and ``SEQ_VOLUME`` events) are passed as event
+type SND_SEQ_OSS_PRIVATE.  The OSS sequencer passes these event 8 byte
+packets without any modification. The lowlevel driver should process these
+events appropriately.
+
+Interface to MIDI Device
+========================
+
+Since the OSS emulation probes the creation and deletion of ALSA MIDI
+sequencer ports automatically by receiving announcement from ALSA
+sequencer, the MIDI devices don't need to be registered explicitly
+like synth devices.
+However, the MIDI port_info registered to ALSA sequencer must include
+a group name ``SND_SEQ_GROUP_DEVICE`` and a capability-bit
+``CAP_READ`` or ``CAP_WRITE``. Also, subscription capabilities,
+``CAP_SUBS_READ`` or ``CAP_SUBS_WRITE``, must be defined, too. If
+these conditions are not satisfied, the port is not registered as OSS
+sequencer MIDI device.
+
+The events via MIDI devices are parsed in OSS sequencer and converted
+to the corresponding ALSA sequencer events. The input from MIDI sequencer
+is also converted to MIDI byte events by OSS sequencer. This works just
+a reverse way of seq_midi module.
+
+Known Problems / TODO's
+=======================
+
+* Patch loading via ALSA instrument layer is not implemented yet.

 The most common problem of the controller is the inaccurate DMA

 map.  As default the driver tries to read from the io-mapped
 position-buffer, and falls back to LPIB if the position-buffer appears

 Codec-Probing Problem
-~~~~~~~~~~~~~~~~~~~~~
+---------------------
 A less often but a more severe problem is the codec probing.  When
 BIOS reports the available codec slots wrongly, the driver gets
 confused and tries to access the non-existing codec slot.  This often
 results in the total screw-up, and destructs the further communication
 with the codec chips.  The symptom appears usually as error messages
 like:
-------------------------------------------------------------------------
-  hda_intel: azx_get_response timeout, switching to polling mode:
-        last cmd=0x12345678

 Since 2.6.29 kernel, the driver has a more robust probing method, so
 this error might happen rarely, though.
 
 On a machine with a broken BIOS, sometimes you need to force the
 driver to probe the codec slots the hardware doesn't report for use.

 Interrupt Handling

-  # echo 1 > /sys/kernel/debug/tracing/events/hda/enable
-------------------------------------------------------------------------
+::
+
+    # echo 1 > /sys/kernel/debug/tracing/events/hda/enable
+
 then after some commands, you can traces from
 /sys/kernel/debug/tracing/trace file.  For example, when you want to
 trace what codec command is sent, enable the tracepoint like:
-------------------------------------------------------------------------
-  # cat /sys/kernel/debug/tracing/trace
-  # tracer: nop
-  #
-  #       TASK-PID    CPU#    TIMESTAMP  FUNCTION

+======================
+Writing an ALSA Driver
+======================
+
+:Author: Takashi Iwai <tiwai@suse.de>
+:Date:   Oct 15, 2007
+:Edition: 0.3.7
+
+Preface
+=======
+
+This document describes how to write an `ALSA (Advanced Linux Sound
+Architecture) <http://www.alsa-project.org/>`__ driver. The document
+focuses mainly on PCI soundcards. In the case of other device types, the
+API might be different, too. However, at least the ALSA kernel API is
+consistent, and therefore it would be still a bit help for writing them.
+
+This document targets people who already have enough C language skills
+and have basic linux kernel programming knowledge. This document doesn't
+explain the general topic of linux kernel coding and doesn't cover
+low-level driver implementation details. It only describes the standard
+way to write a PCI sound driver on ALSA.
+
+If you are already familiar with the older ALSA ver.0.5.x API, you can
+check the drivers such as ``sound/pci/es1938.c`` or
+``sound/pci/maestro3.c`` which have also almost the same code-base in
+the ALSA 0.5.x tree, so you can compare the differences.
+
+This document is still a draft version. Any feedback and corrections,
+please!!
+
+File Tree Structure
+===================
+
+General
+-------
+
+The ALSA drivers are provided in two ways.
+
+One is the trees provided as a tarball or via cvs from the ALSA's ftp
+site, and another is the 2.6 (or later) Linux kernel tree. To
+synchronize both, the ALSA driver tree is split into two different
+trees: alsa-kernel and alsa-driver. The former contains purely the
+source code for the Linux 2.6 (or later) tree. This tree is designed
+only for compilation on 2.6 or later environment. The latter,
+alsa-driver, contains many subtle files for compiling ALSA drivers
+outside of the Linux kernel tree, wrapper functions for older 2.2 and
+2.4 kernels, to adapt the latest kernel API, and additional drivers
+which are still in development or in tests. The drivers in alsa-driver
+tree will be moved to alsa-kernel (and eventually to the 2.6 kernel
+tree) when they are finished and confirmed to work fine.
+
+The file tree structure of ALSA driver is depicted below. Both
+alsa-kernel and alsa-driver have almost the same file structure, except
+for “core” directory. It's named as “acore” in alsa-driver tree.

+The codes for PCM and mixer OSS emulation modules are stored in this
+directory. The rawmidi OSS emulation is included in the ALSA rawmidi
+code since it's quite small. The sequencer code is stored in
+``core/seq/oss`` directory (see `below <#core-seq-oss>`__).
+
+core/ioctl32
+~~~~~~~~~~~~
+
+This directory contains the 32bit-ioctl wrappers for 64bit architectures
+such like x86-64, ppc64 and sparc64. For 32bit and alpha architectures,
+these are not compiled.
+
+core/seq
+~~~~~~~~
+
+This directory and its sub-directories are for the ALSA sequencer. This
+directory contains the sequencer core and primary sequencer modules such
+like snd-seq-midi, snd-seq-virmidi, etc. They are compiled only when
+``CONFIG_SND_SEQUENCER`` is set in the kernel config.
+
+core/seq/oss
+~~~~~~~~~~~~
+
+This contains the OSS sequencer emulation codes.
+
+core/seq/instr
+~~~~~~~~~~~~~~
+
+This directory contains the modules for the sequencer instrument layer.
+
+include directory
+-----------------
+
+This is the place for the public header files of ALSA drivers, which are
+to be exported to user-space, or included by several files at different
+directories. Basically, the private header files should not be placed in
+this directory, but you may still find files there, due to historical
+reasons :)
+
+drivers directory
+-----------------
+
+This directory contains code shared among different drivers on different
+architectures. They are hence supposed not to be architecture-specific.
+For example, the dummy pcm driver and the serial MIDI driver are found
+in this directory. In the sub-directories, there is code for components
+which are independent from bus and cpu architectures.
+
+drivers/mpu401
+~~~~~~~~~~~~~~
+
+The MPU401 and MPU401-UART modules are stored here.
+
+drivers/opl3 and opl4
+~~~~~~~~~~~~~~~~~~~~~
+
+The OPL3 and OPL4 FM-synth stuff is found here.
+
+i2c directory
+-------------
+
+This contains the ALSA i2c components.
+
+Although there is a standard i2c layer on Linux, ALSA has its own i2c
+code for some cards, because the soundcard needs only a simple operation
+and the standard i2c API is too complicated for such a purpose.
+
+i2c/l3
+~~~~~~
+
+This is a sub-directory for ARM L3 i2c.
+
+synth directory
+---------------
+
+This contains the synth middle-level modules.
+
+So far, there is only Emu8000/Emu10k1 synth driver under the
+``synth/emux`` sub-directory.
+
+pci directory
+-------------
+
+This directory and its sub-directories hold the top-level card modules
+for PCI soundcards and the code specific to the PCI BUS.
+
+The drivers compiled from a single file are stored directly in the pci
+directory, while the drivers with several source files are stored on
+their own sub-directory (e.g. emu10k1, ice1712).
+
+isa directory
+-------------
+
+This directory and its sub-directories hold the top-level card modules
+for ISA soundcards.
+
+arm, ppc, and sparc directories
+-------------------------------
+
+They are used for top-level card modules which are specific to one of
+these architectures.
+
+usb directory
+-------------
+
+This directory contains the USB-audio driver. In the latest version, the
+USB MIDI driver is integrated in the usb-audio driver.
+
+pcmcia directory
+----------------
+
+The PCMCIA, especially PCCard drivers will go here. CardBus drivers will
+be in the pci directory, because their API is identical to that of
+standard PCI cards.
+
+oss directory
+-------------
+
+The OSS/Lite source files are stored here in Linux 2.6 (or later) tree.
+In the ALSA driver tarball, this directory is empty, of course :)
+
+Basic Flow for PCI Drivers
+==========================
+
+Outline
+-------
+
+The minimum flow for PCI soundcards is as follows:
+
+-  define the PCI ID table (see the section `PCI Entries`_).
+
+-  create ``probe`` callback.
+
+-  create ``remove`` callback.
+
+-  create a :c:type:`struct pci_driver <pci_driver>` structure
+   containing the three pointers above.
+
+-  create an ``init`` function just calling the
+   :c:func:`pci_register_driver()` to register the pci_driver
+   table defined above.
+
+-  create an ``exit`` function to call the
+   :c:func:`pci_unregister_driver()` function.

+              pci_set_drvdata(pci, NULL);
+      }
+
+
+
+Driver Constructor
+------------------
+
+The real constructor of PCI drivers is the ``probe`` callback. The
+``probe`` callback and other component-constructors which are called
+from the ``probe`` callback cannot be used with the ``__init`` prefix
+because any PCI device could be a hotplug device.
+
+In the ``probe`` callback, the following scheme is often used.
+
+1) Check and increment the device index.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+  static int dev;
+  ....
+  if (dev >= SNDRV_CARDS)
+          return -ENODEV;
+  if (!enable[dev]) {
+          dev++;
+          return -ENOENT;
+  }
+
+
+where ``enable[dev]`` is the module option.
+
+Each time the ``probe`` callback is called, check the availability of
+the device. If not available, simply increment the device index and
+returns. dev will be incremented also later (`step 7
+<#set-the-pci-driver-data-and-return-zero>`__).
+
+2) Create a card instance
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+  struct snd_card *card;
+  int err;
+  ....
+  err = snd_card_new(&pci->dev, index[dev], id[dev], THIS_MODULE,
+                     0, &card);
+
+
+The details will be explained in the section `Management of Cards and
+Components`_.
+
+3) Create a main component
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In this part, the PCI resources are allocated.
+
+::
+
+  struct mychip *chip;
+  ....
+  err = snd_mychip_create(card, pci, &chip);
+  if (err < 0) {
+          snd_card_free(card);
+          return err;
+  }
+
+The details will be explained in the section `PCI Resource
+Management`_.
+
+4) Set the driver ID and name strings.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+  strcpy(card->driver, "My Chip");
+  strcpy(card->shortname, "My Own Chip 123");
+  sprintf(card->longname, "%s at 0x%lx irq %i",
+          card->shortname, chip->ioport, chip->irq);
+
+The driver field holds the minimal ID string of the chip. This is used
+by alsa-lib's configurator, so keep it simple but unique. Even the
+same driver can have different driver IDs to distinguish the
+functionality of each chip type.
+
+The shortname field is a string shown as more verbose name. The longname
+field contains the information shown in ``/proc/asound/cards``.
+
+5) Create other components, such as mixer, MIDI, etc.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here you define the basic components such as `PCM <#PCM-Interface>`__,
+mixer (e.g. `AC97 <#API-for-AC97-Codec>`__), MIDI (e.g.
+`MPU-401 <#MIDI-MPU401-UART-Interface>`__), and other interfaces.
+Also, if you want a `proc file <#Proc-Interface>`__, define it here,
+too.
+
+6) Register the card instance.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+  err = snd_card_register(card);
+  if (err < 0) {
+          snd_card_free(card);
+          return err;
+  }
+
+Will be explained in the section `Management of Cards and
+Components`_, too.
+
+7) Set the PCI driver data and return zero.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+  pci_set_drvdata(pci, card);
+  dev++;
+  return 0;
+
+In the above, the card record is stored. This pointer is used in the
+remove callback and power-management callbacks, too.
+
+Destructor
+----------
+
+The destructor, remove callback, simply releases the card instance. Then
+the ALSA middle layer will release all the attached components
+automatically.
+
+It would be typically like the following:
+
+::
+
+  static void snd_mychip_remove(struct pci_dev *pci)
+  {
+          snd_card_free(pci_get_drvdata(pci));
+          pci_set_drvdata(pci, NULL);
+  }
+
+
+The above code assumes that the card pointer is set to the PCI driver
+data.
+
+Header Files
+------------
+
+For the above example, at least the following include files are
+necessary.
+
+::
+
+  #include <linux/init.h>
+  #include <linux/pci.h>
+  #include <linux/slab.h>
+  #include <sound/core.h>
+  #include <sound/initval.h>
+
+where the last one is necessary only when module options are defined
+in the source file. If the code is split into several files, the files
+without module options don't need them.
+
+In addition to these headers, you'll need ``<linux/interrupt.h>`` for
+interrupt handling, and ``<asm/io.h>`` for I/O access. If you use the
+:c:func:`mdelay()` or :c:func:`udelay()` functions, you'll need
+to include ``<linux/delay.h>`` too.
+
+The ALSA interfaces like the PCM and control APIs are defined in other
+``<sound/xxx.h>`` header files. They have to be included after
+``<sound/core.h>``.
+
+Management of Cards and Components
+==================================
+
+Card Instance
+-------------
+
+For each soundcard, a “card” record must be allocated.
+
+A card record is the headquarters of the soundcard. It manages the whole
+list of devices (components) on the soundcard, such as PCM, mixers,
+MIDI, synthesizer, and so on. Also, the card record holds the ID and the
+name strings of the card, manages the root of proc files, and controls
+the power-management states and hotplug disconnections. The component
+list on the card record is used to manage the correct release of
+resources at destruction.
+
+As mentioned above, to create a card instance, call
+:c:func:`snd_card_new()`.
+
+::
+
+  struct snd_card *card;
+  int err;
+  err = snd_card_new(&pci->dev, index, id, module, extra_size, &card);
+
+
+The function takes six arguments: the parent device pointer, the
+card-index number, the id string, the module pointer (usually
+``THIS_MODULE``), the size of extra-data space, and the pointer to
+return the card instance. The extra_size argument is used to allocate
+card->private_data for the chip-specific data. Note that these data are
+allocated by :c:func:`snd_card_new()`.
+
+The first argument, the pointer of struct :c:type:`struct device
+<device>`, specifies the parent device. For PCI devices, typically
+``&pci->`` is passed there.
+
+Components
+----------
+
+After the card is created, you can attach the components (devices) to
+the card instance. In an ALSA driver, a component is represented as a
+:c:type:`struct snd_device <snd_device>` object. A component
+can be a PCM instance, a control interface, a raw MIDI interface, etc.
+Each such instance has one component entry.
+
+A component can be created via :c:func:`snd_device_new()`
+function.
+
+::
+
+  snd_device_new(card, SNDRV_DEV_XXX, chip, &ops);
+
+This takes the card pointer, the device-level (``SNDRV_DEV_XXX``), the
+data pointer, and the callback pointers (``&ops``). The device-level
+defines the type of components and the order of registration and
+de-registration. For most components, the device-level is already
+defined. For a user-defined component, you can use
+``SNDRV_DEV_LOWLEVEL``.
+
+This function itself doesn't allocate the data space. The data must be
+allocated manually beforehand, and its pointer is passed as the
+argument. This pointer (``chip`` in the above example) is used as the
+identifier for the instance.
+
+Each pre-defined ALSA component such as ac97 and pcm calls
+:c:func:`snd_device_new()` inside its constructor. The destructor
+for each component is defined in the callback pointers. Hence, you don't
+need to take care of calling a destructor for such a component.
+
+If you wish to create your own component, you need to set the destructor
+function to the dev_free callback in the ``ops``, so that it can be
+released automatically via :c:func:`snd_card_free()`. The next
+example will show an implementation of chip-specific data.
+
+Chip-Specific Data
+------------------
+
+Chip-specific information, e.g. the I/O port address, its resource
+pointer, or the irq number, is stored in the chip-specific record.
+
+::
+
+  struct mychip {
+          ....
+  };
+
+
+In general, there are two ways of allocating the chip record.
+
+1. Allocating via :c:func:`snd_card_new()`.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+As mentioned above, you can pass the extra-data-length to the 5th
+argument of :c:func:`snd_card_new()`, i.e.
+
+::
+
+  err = snd_card_new(&pci->dev, index[dev], id[dev], THIS_MODULE,
+                     sizeof(struct mychip), &card);
+
+:c:type:`struct mychip <mychip>` is the type of the chip record.
+
+In return, the allocated record can be accessed as
+
+::
+
+  struct mychip *chip = card->private_data;
+
+With this method, you don't have to allocate twice. The record is
+released together with the card instance.
+
+2. Allocating an extra device.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After allocating a card instance via :c:func:`snd_card_new()`
+(with ``0`` on the 4th arg), call :c:func:`kzalloc()`.
+
+::
+
+  struct snd_card *card;
+  struct mychip *chip;
+  err = snd_card_new(&pci->dev, index[dev], id[dev], THIS_MODULE,
+                     0, &card);
+  .....
+  chip = kzalloc(sizeof(*chip), GFP_KERNEL);
+
+The chip record should have the field to hold the card pointer at least,
+
+::
+
+  struct mychip {
+          struct snd_card *card;
+          ....
+  };
+
+
+Then, set the card pointer in the returned chip instance.
+
+::
+
+  chip->card = card;
+
+Next, initialize the fields, and register this chip record as a
+low-level device with a specified ``ops``,
+
+::
+
+  static struct snd_device_ops ops = {
+          .dev_free =        snd_mychip_dev_free,
+  };
+  ....
+  snd_device_new(card, SNDRV_DEV_LOWLEVEL, chip, &ops);
+
+:c:func:`snd_mychip_dev_free()` is the device-destructor
+function, which will call the real destructor.
+
+::
+
+  static int snd_mychip_dev_free(struct snd_device *device)
+  {
+          return snd_mychip_free(device->device_data);
+  }
+
+where :c:func:`snd_mychip_free()` is the real destructor.
+
+Registration and Release
+------------------------
+
+After all components are assigned, register the card instance by calling
+:c:func:`snd_card_register()`. Access to the device files is
+enabled at this point. That is, before
+:c:func:`snd_card_register()` is called, the components are safely
+inaccessible from external side. If this call fails, exit the probe
+function after releasing the card via :c:func:`snd_card_free()`.
+
+For releasing the card instance, you can call simply
+:c:func:`snd_card_free()`. As mentioned earlier, all components
+are released automatically by this call.
+
+For a device which allows hotplugging, you can use
+:c:func:`snd_card_free_when_closed()`. This one will postpone
+the destruction until all devices are closed.
+
+PCI Resource Management
+=======================
+
+Full Code Example
+-----------------
+
+In this section, we'll complete the chip-specific constructor,
+destructor and PCI entries. Example code is shown first, below.
+
+::
+
+      struct mychip {
+              struct snd_card *card;
+              struct pci_dev *pci;
+
+              unsigned long port;
+              int irq;
+      };
+
+      static int snd_mychip_free(struct mychip *chip)
+      {
+              /* disable hardware here if any */
+              .... /* (not implemented in this document) */
+
+              /* release the irq */
+              if (chip->irq >= 0)

+
+Some Hafta's
+------------
+
+The allocation of PCI resources is done in the ``probe`` function, and
+usually an extra :c:func:`xxx_create()` function is written for this
+purpose.
+
+In the case of PCI devices, you first have to call the
+:c:func:`pci_enable_device()` function before allocating
+resources. Also, you need to set the proper PCI DMA mask to limit the
+accessed I/O range. In some cases, you might need to call
+:c:func:`pci_set_master()` function, too.
+
+Suppose the 28bit mask, and the code to be added would be like:
+
+::
+
+  err = pci_enable_device(pci);
+  if (err < 0)
+          return err;
+  if (pci_set_dma_mask(pci, DMA_BIT_MASK(28)) < 0 ||
+      pci_set_consistent_dma_mask(pci, DMA_BIT_MASK(28)) < 0) {
+          printk(KERN_ERR "error to set 28bit mask DMA\n");
+          pci_disable_device(pci);
+          return -ENXIO;
+  }
+  
+
+Resource Allocation
+-------------------
+
+The allocation of I/O ports and irqs is done via standard kernel
+functions. Unlike ALSA ver.0.5.x., there are no helpers for that. And
+these resources must be released in the destructor function (see below).
+Also, on ALSA 0.9.x, you don't need to allocate (pseudo-)DMA for PCI
+like in ALSA 0.5.x.
+
+Now assume that the PCI device has an I/O port with 8 bytes and an
+interrupt. Then :c:type:`struct mychip <mychip>` will have the
+following fields:
+
+::
+
+  struct mychip {
+          struct snd_card *card;
+
+          unsigned long port;
+          int irq;
+  };
+
+
+For an I/O port (and also a memory region), you need to have the
+resource pointer for the standard resource management. For an irq, you
+have to keep only the irq number (integer). But you need to initialize
+this number as -1 before actual allocation, since irq 0 is valid. The
+port address and its resource pointer can be initialized as null by
+:c:func:`kzalloc()` automatically, so you don't have to take care of
+resetting them.
+
+The allocation of an I/O port is done like this:
+
+::
+
+  err = pci_request_regions(pci, "My Chip");
+  if (err < 0) { 
+          kfree(chip);
+          pci_disable_device(pci);
+          return err;
+  }
+  chip->port = pci_resource_start(pci, 0);
+
+It will reserve the I/O port region of 8 bytes of the given PCI device.
+The returned value, ``chip->res_port``, is allocated via
+:c:func:`kmalloc()` by :c:func:`request_region()`. The pointer
+must be released via :c:func:`kfree()`, but there is a problem with
+this. This issue will be explained later.
+
+The allocation of an interrupt source is done like this:
+
+::
+
+  if (request_irq(pci->irq, snd_mychip_interrupt,
+                  IRQF_SHARED, KBUILD_MODNAME, chip)) {
+          printk(KERN_ERR "cannot grab irq %d\n", pci->irq);
+          snd_mychip_free(chip);
+          return -EBUSY;
+  }
+  chip->irq = pci->irq;
+
+where :c:func:`snd_mychip_interrupt()` is the interrupt handler
+defined `later <#pcm-interface-interrupt-handler>`__. Note that
+``chip->irq`` should be defined only when :c:func:`request_irq()`
+succeeded.
+
+On the PCI bus, interrupts can be shared. Thus, ``IRQF_SHARED`` is used
+as the interrupt flag of :c:func:`request_irq()`.
+
+The last argument of :c:func:`request_irq()` is the data pointer
+passed to the interrupt handler. Usually, the chip-specific record is
+used for that, but you can use what you like, too.
+
+I won't give details about the interrupt handler at this point, but at
+least its appearance can be explained now. The interrupt handler looks
+usually like the following:
+
+::
+
+  static irqreturn_t snd_mychip_interrupt(int irq, void *dev_id)
+  {
+          struct mychip *chip = dev_id;
+          ....
+          return IRQ_HANDLED;
+  }
+
+
+Now let's write the corresponding destructor for the resources above.
+The role of destructor is simple: disable the hardware (if already
+activated) and release the resources. So far, we have no hardware part,
+so the disabling code is not written here.
+
+To release the resources, the “check-and-release” method is a safer way.
+For the interrupt, do like this:
+
+::
+
+  if (chip->irq >= 0)
+          free_irq(chip->irq, chip);
+
+Since the irq number can start from 0, you should initialize
+``chip->irq`` with a negative value (e.g. -1), so that you can check
+the validity of the irq number as above.
+
+When you requested I/O ports or memory regions via
+:c:func:`pci_request_region()` or
+:c:func:`pci_request_regions()` like in this example, release the
+resource(s) using the corresponding function,
+:c:func:`pci_release_region()` or
+:c:func:`pci_release_regions()`.
+
+::
+
+  pci_release_regions(chip->pci);
+
+When you requested manually via :c:func:`request_region()` or
+:c:func:`request_mem_region()`, you can release it via
+:c:func:`release_resource()`. Suppose that you keep the resource
+pointer returned from :c:func:`request_region()` in
+chip->res_port, the release procedure looks like:
+
+::
+
+  release_and_free_resource(chip->res_port);
+
+Don't forget to call :c:func:`pci_disable_device()` before the
+end.
+
+And finally, release the chip-specific record.
+
+::
+
+  kfree(chip);
+
+We didn't implement the hardware disabling part in the above. If you
+need to do this, please note that the destructor may be called even
+before the initialization of the chip is completed. It would be better
+to have a flag to skip hardware disabling if the hardware was not
+initialized yet.
+
+When the chip-data is assigned to the card using
+:c:func:`snd_device_new()` with ``SNDRV_DEV_LOWLELVEL`` , its
+destructor is called at the last. That is, it is assured that all other
+components like PCMs and controls have already been released. You don't
+have to stop PCMs, etc. explicitly, but just call low-level hardware
+stopping.
+
+The management of a memory-mapped region is almost as same as the
+management of an I/O port. You'll need three fields like the
+following:
+
+::
+
+  struct mychip {
+          ....
+          unsigned long iobase_phys;
+          void __iomem *iobase_virt;
+  };
+
+and the allocation would be like below:
+
+::
+
+  if ((err = pci_request_regions(pci, "My Chip")) < 0) {
+          kfree(chip);
+          return err;
+  }
+  chip->iobase_phys = pci_resource_start(pci, 0);
+  chip->iobase_virt = ioremap_nocache(chip->iobase_phys,
+                                      pci_resource_len(pci, 0));
+
+and the corresponding destructor would be:
+
+::
+
+  static int snd_mychip_free(struct mychip *chip)
+  {
+          ....
+          if (chip->iobase_virt)
+                  iounmap(chip->iobase_virt);
+          ....
+          pci_release_regions(chip->pci);
+          ....
+  }
+
+PCI Entries
+-----------
+
+So far, so good. Let's finish the missing PCI stuff. At first, we need a
+:c:type:`struct pci_device_id <pci_device_id>` table for
+this chipset. It's a table of PCI vendor/device ID number, and some
+masks.
+
+For example,
+
+::
+
+  static struct pci_device_id snd_mychip_ids[] = {
+          { PCI_VENDOR_ID_FOO, PCI_DEVICE_ID_BAR,
+            PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0, },
+          ....
+          { 0, }
+  };
+  MODULE_DEVICE_TABLE(pci, snd_mychip_ids);
+
+The first and second fields of the :c:type:`struct pci_device_id
+<pci_device_id>` structure are the vendor and device IDs. If you
+have no reason to filter the matching devices, you can leave the
+remaining fields as above. The last field of the :c:type:`struct
+pci_device_id <pci_device_id>` struct contains private data
+for this entry. You can specify any value here, for example, to define
+specific operations for supported device IDs. Such an example is found
+in the intel8x0 driver.
+
+The last entry of this list is the terminator. You must specify this
+all-zero entry.
+
+Then, prepare the :c:type:`struct pci_driver <pci_driver>`
+record:
+
+::
+
+  static struct pci_driver driver = {
+          .name = KBUILD_MODNAME,
+          .id_table = snd_mychip_ids,
+          .probe = snd_mychip_probe,
+          .remove = snd_mychip_remove,
+  };
+
+The ``probe`` and ``remove`` functions have already been defined in
+the previous sections. The ``name`` field is the name string of this
+device. Note that you must not use a slash “/” in this string.
+
+And at last, the module entries:
+
+::
+
+  static int __init alsa_card_mychip_init(void)
+  {
+          return pci_register_driver(&driver);
+  }
+
+  static void __exit alsa_card_mychip_exit(void)
+  {
+          pci_unregister_driver(&driver);
+  }
+
+  module_init(alsa_card_mychip_init)
+  module_exit(alsa_card_mychip_exit)
+
+Note that these module entries are tagged with ``__init`` and ``__exit``
+prefixes.
+
+Oh, one thing was forgotten. If you have no exported symbols, you need
+to declare it in 2.2 or 2.4 kernels (it's not necessary in 2.6 kernels).
+
+::
+
+  EXPORT_NO_SYMBOLS;
+
+That's all!
+
+PCM Interface
+=============
+
+General
+-------
+
+The PCM middle layer of ALSA is quite powerful and it is only necessary
+for each driver to implement the low-level functions to access its
+hardware.
+
+For accessing to the PCM layer, you need to include ``<sound/pcm.h>``
+first. In addition, ``<sound/pcm_params.h>`` might be needed if you
+access to some functions related with hw_param.
+
+Each card device can have up to four pcm instances. A pcm instance
+corresponds to a pcm device file. The limitation of number of instances
+comes only from the available bit size of the Linux's device numbers.
+Once when 64bit device number is used, we'll have more pcm instances
+available.
+
+A pcm instance consists of pcm playback and capture streams, and each
+pcm stream consists of one or more pcm substreams. Some soundcards
+support multiple playback functions. For example, emu10k1 has a PCM
+playback of 32 stereo substreams. In this case, at each open, a free
+substream is (usually) automatically chosen and opened. Meanwhile, when
+only one substream exists and it was already opened, the successful open
+will either block or error with ``EAGAIN`` according to the file open
+mode. But you don't have to care about such details in your driver. The
+PCM middle layer will take care of such work.

+
+
+PCM Constructor
+---------------
+
+A pcm instance is allocated by the :c:func:`snd_pcm_new()`
+function. It would be better to create a constructor for pcm, namely,
+
+::
+
+  static int snd_mychip_new_pcm(struct mychip *chip)
+  {
+          struct snd_pcm *pcm;
+          int err;
+
+          err = snd_pcm_new(chip->card, "My Chip", 0, 1, 1, &pcm);
+          if (err < 0) 
+                  return err;
+          pcm->private_data = chip;
+          strcpy(pcm->name, "My Chip");
+          chip->pcm = pcm;
+	  ....
+          return 0;
+  }
+
+The :c:func:`snd_pcm_new()` function takes four arguments. The
+first argument is the card pointer to which this pcm is assigned, and
+the second is the ID string.
+
+The third argument (``index``, 0 in the above) is the index of this new
+pcm. It begins from zero. If you create more than one pcm instances,
+specify the different numbers in this argument. For example, ``index =
+1`` for the second PCM device.
+
+The fourth and fifth arguments are the number of substreams for playback
+and capture, respectively. Here 1 is used for both arguments. When no
+playback or capture substreams are available, pass 0 to the
+corresponding argument.
+
+If a chip supports multiple playbacks or captures, you can specify more
+numbers, but they must be handled properly in open/close, etc.
+callbacks. When you need to know which substream you are referring to,
+then it can be obtained from :c:type:`struct snd_pcm_substream
+<snd_pcm_substream>` data passed to each callback as follows:
+
+::
+
+  struct snd_pcm_substream *substream;
+  int index = substream->number;
+
+
+After the pcm is created, you need to set operators for each pcm stream.
+
+::
+
+  snd_pcm_set_ops(pcm, SNDRV_PCM_STREAM_PLAYBACK,
+                  &snd_mychip_playback_ops);
+  snd_pcm_set_ops(pcm, SNDRV_PCM_STREAM_CAPTURE,
+                  &snd_mychip_capture_ops);
+
+The operators are defined typically like this:
+
+::
+
+  static struct snd_pcm_ops snd_mychip_playback_ops = {
+          .open =        snd_mychip_pcm_open,
+          .close =       snd_mychip_pcm_close,
+          .ioctl =       snd_pcm_lib_ioctl,
+          .hw_params =   snd_mychip_pcm_hw_params,
+          .hw_free =     snd_mychip_pcm_hw_free,
+          .prepare =     snd_mychip_pcm_prepare,
+          .trigger =     snd_mychip_pcm_trigger,
+          .pointer =     snd_mychip_pcm_pointer,
+  };
+
+All the callbacks are described in the Operators_ subsection.
+
+After setting the operators, you probably will want to pre-allocate the
+buffer. For the pre-allocation, simply call the following:
+
+::
+
+  snd_pcm_lib_preallocate_pages_for_all(pcm, SNDRV_DMA_TYPE_DEV,
+                                        snd_dma_pci_data(chip->pci),
+                                        64*1024, 64*1024);
+
+It will allocate a buffer up to 64kB as default. Buffer management
+details will be described in the later section `Buffer and Memory
+Management`_.
+
+Additionally, you can set some extra information for this pcm in
+``pcm->info_flags``. The available values are defined as
+``SNDRV_PCM_INFO_XXX`` in ``<sound/asound.h>``, which is used for the
+hardware definition (described later). When your soundchip supports only
+half-duplex, specify like this:
+
+::
+
+  pcm->info_flags = SNDRV_PCM_INFO_HALF_DUPLEX;
+
+
+... And the Destructor?
+-----------------------
+
+The destructor for a pcm instance is not always necessary. Since the pcm
+device will be released by the middle layer code automatically, you
+don't have to call the destructor explicitly.
+
+The destructor would be necessary if you created special records
+internally and needed to release them. In such a case, set the
+destructor function to ``pcm->private_free``:
+
+::
+
+      static void mychip_pcm_free(struct snd_pcm *pcm)
+      {
+              struct mychip *chip = snd_pcm_chip(pcm);
+              /* free your own data */
+              kfree(chip->my_private_pcm_data);
+              /* do what you like else */
+              ....
+      }
+
+      static int snd_mychip_new_pcm(struct mychip *chip)
+      {
+              struct snd_pcm *pcm;
+              ....
+              /* allocate your own data */
+              chip->my_private_pcm_data = kmalloc(...);
+              /* set the destructor */
+              pcm->private_data = chip;
+              pcm->private_free = mychip_pcm_free;
+              ....
+      }
+
+
+
+Runtime Pointer - The Chest of PCM Information
+----------------------------------------------
+
+When the PCM substream is opened, a PCM runtime instance is allocated
+and assigned to the substream. This pointer is accessible via
+``substream->runtime``. This runtime pointer holds most information you
+need to control the PCM: the copy of hw_params and sw_params
+configurations, the buffer pointers, mmap records, spinlocks, etc.
+
+The definition of runtime instance is found in ``<sound/pcm.h>``. Here
+are the contents of this file:
+
+::
+
+  struct _snd_pcm_runtime {

+  };
+
+
+For the operators (callbacks) of each sound driver, most of these
+records are supposed to be read-only. Only the PCM middle-layer changes
+/ updates them. The exceptions are the hardware description (hw) DMA
+buffer information and the private data. Besides, if you use the
+standard buffer allocation method via
+:c:func:`snd_pcm_lib_malloc_pages()`, you don't need to set the
+DMA buffer information by yourself.
+
+In the sections below, important records are explained.
+
+Hardware Description
+~~~~~~~~~~~~~~~~~~~~
+
+The hardware descriptor (:c:type:`struct snd_pcm_hardware
+<snd_pcm_hardware>`) contains the definitions of the fundamental
+hardware configuration. Above all, you'll need to define this in the
+`PCM open callback`_. Note that the runtime instance holds the copy of
+the descriptor, not the pointer to the existing descriptor. That is,
+in the open callback, you can modify the copied descriptor
+(``runtime->hw``) as you need. For example, if the maximum number of
+channels is 1 only on some chip models, you can still use the same
+hardware descriptor and change the channels_max later:
+
+::
+
+          struct snd_pcm_runtime *runtime = substream->runtime;
+          ...
+          runtime->hw = snd_mychip_playback_hw; /* common definition */
+          if (chip->model == VERY_OLD_ONE)
+                  runtime->hw.channels_max = 1;
+
+Typically, you'll have a hardware descriptor as below:
+
+::
+
+  static struct snd_pcm_hardware snd_mychip_playback_hw = {
+          .info = (SNDRV_PCM_INFO_MMAP |
+                   SNDRV_PCM_INFO_INTERLEAVED |
+                   SNDRV_PCM_INFO_BLOCK_TRANSFER |
+                   SNDRV_PCM_INFO_MMAP_VALID),
+          .formats =          SNDRV_PCM_FMTBIT_S16_LE,
+          .rates =            SNDRV_PCM_RATE_8000_48000,
+          .rate_min =         8000,
+          .rate_max =         48000,
+          .channels_min =     2,
+          .channels_max =     2,
+          .buffer_bytes_max = 32768,
+          .period_bytes_min = 4096,
+          .period_bytes_max = 32768,
+          .periods_min =      1,
+          .periods_max =      1024,
+  };
+
+-  The ``info`` field contains the type and capabilities of this
+   pcm. The bit flags are defined in ``<sound/asound.h>`` as
+   ``SNDRV_PCM_INFO_XXX``. Here, at least, you have to specify whether
+   the mmap is supported and which interleaved format is
+   supported. When the hardware supports mmap, add the
+   ``SNDRV_PCM_INFO_MMAP`` flag here. When the hardware supports the
+   interleaved or the non-interleaved formats,
+   ``SNDRV_PCM_INFO_INTERLEAVED`` or ``SNDRV_PCM_INFO_NONINTERLEAVED``
+   flag must be set, respectively. If both are supported, you can set
+   both, too.
+
+   In the above example, ``MMAP_VALID`` and ``BLOCK_TRANSFER`` are
+   specified for the OSS mmap mode. Usually both are set. Of course,
+   ``MMAP_VALID`` is set only if the mmap is really supported.
+
+   The other possible flags are ``SNDRV_PCM_INFO_PAUSE`` and
+   ``SNDRV_PCM_INFO_RESUME``. The ``PAUSE`` bit means that the pcm
+   supports the “pause” operation, while the ``RESUME`` bit means that
+   the pcm supports the full “suspend/resume” operation. If the
+   ``PAUSE`` flag is set, the ``trigger`` callback below must handle
+   the corresponding (pause push/release) commands. The suspend/resume
+   trigger commands can be defined even without the ``RESUME``
+   flag. See `Power Management`_ section for details.
+
+   When the PCM substreams can be synchronized (typically,
+   synchronized start/stop of a playback and a capture streams), you
+   can give ``SNDRV_PCM_INFO_SYNC_START``, too. In this case, you'll
+   need to check the linked-list of PCM substreams in the trigger
+   callback. This will be described in the later section.
+
+-  ``formats`` field contains the bit-flags of supported formats
+   (``SNDRV_PCM_FMTBIT_XXX``). If the hardware supports more than one
+   format, give all or'ed bits. In the example above, the signed 16bit
+   little-endian format is specified.
+
+-  ``rates`` field contains the bit-flags of supported rates
+   (``SNDRV_PCM_RATE_XXX``). When the chip supports continuous rates,
+   pass ``CONTINUOUS`` bit additionally. The pre-defined rate bits are
+   provided only for typical rates. If your chip supports
+   unconventional rates, you need to add the ``KNOT`` bit and set up
+   the hardware constraint manually (explained later).
+
+-  ``rate_min`` and ``rate_max`` define the minimum and maximum sample
+   rate. This should correspond somehow to ``rates`` bits.
+
+-  ``channel_min`` and ``channel_max`` define, as you might already
+   expected, the minimum and maximum number of channels.
+
+-  ``buffer_bytes_max`` defines the maximum buffer size in
+   bytes. There is no ``buffer_bytes_min`` field, since it can be
+   calculated from the minimum period size and the minimum number of
+   periods. Meanwhile, ``period_bytes_min`` and define the minimum and
+   maximum size of the period in bytes. ``periods_max`` and
+   ``periods_min`` define the maximum and minimum number of periods in
+   the buffer.
+
+   The “period” is a term that corresponds to a fragment in the OSS
+   world. The period defines the size at which a PCM interrupt is
+   generated. This size strongly depends on the hardware. Generally,
+   the smaller period size will give you more interrupts, that is,
+   more controls. In the case of capture, this size defines the input
+   latency. On the other hand, the whole buffer size defines the
+   output latency for the playback direction.
+
+-  There is also a field ``fifo_size``. This specifies the size of the
+   hardware FIFO, but currently it is neither used in the driver nor
+   in the alsa-lib. So, you can ignore this field.
+
+PCM Configurations
+~~~~~~~~~~~~~~~~~~
+
+Ok, let's go back again to the PCM runtime records. The most
+frequently referred records in the runtime instance are the PCM
+configurations. The PCM configurations are stored in the runtime
+instance after the application sends ``hw_params`` data via
+alsa-lib. There are many fields copied from hw_params and sw_params
+structs. For example, ``format`` holds the format type chosen by the
+application. This field contains the enum value
+``SNDRV_PCM_FORMAT_XXX``.
+
+One thing to be noted is that the configured buffer and period sizes
+are stored in “frames” in the runtime. In the ALSA world, ``1 frame =
+channels \* samples-size``. For conversion between frames and bytes,
+you can use the :c:func:`frames_to_bytes()` and
+:c:func:`bytes_to_frames()` helper functions.
+
+::
+
+  period_bytes = frames_to_bytes(runtime, runtime->period_size);
+
+Also, many software parameters (sw_params) are stored in frames, too.
+Please check the type of the field. ``snd_pcm_uframes_t`` is for the
+frames as unsigned integer while ``snd_pcm_sframes_t`` is for the
+frames as signed integer.
+
+DMA Buffer Information
+~~~~~~~~~~~~~~~~~~~~~~
+
+The DMA buffer is defined by the following four fields, ``dma_area``,
+``dma_addr``, ``dma_bytes`` and ``dma_private``. The ``dma_area``
+holds the buffer pointer (the logical address). You can call
+:c:func:`memcpy()` from/to this pointer. Meanwhile, ``dma_addr`` holds
+the physical address of the buffer. This field is specified only when
+the buffer is a linear buffer. ``dma_bytes`` holds the size of buffer
+in bytes. ``dma_private`` is used for the ALSA DMA allocator.
+
+If you use a standard ALSA function,
+:c:func:`snd_pcm_lib_malloc_pages()`, for allocating the buffer,
+these fields are set by the ALSA middle layer, and you should *not*
+change them by yourself. You can read them but not write them. On the
+other hand, if you want to allocate the buffer by yourself, you'll
+need to manage it in hw_params callback. At least, ``dma_bytes`` is
+mandatory. ``dma_area`` is necessary when the buffer is mmapped. If
+your driver doesn't support mmap, this field is not
+necessary. ``dma_addr`` is also optional. You can use dma_private as
+you like, too.
+
+Running Status
+~~~~~~~~~~~~~~
+
+The running status can be referred via ``runtime->status``. This is
+the pointer to the :c:type:`struct snd_pcm_mmap_status
+<snd_pcm_mmap_status>` record. For example, you can get the current
+DMA hardware pointer via ``runtime->status->hw_ptr``.
+
+The DMA application pointer can be referred via ``runtime->control``,
+which points to the :c:type:`struct snd_pcm_mmap_control
+<snd_pcm_mmap_control>` record. However, accessing directly to
+this value is not recommended.
+
+Private Data
+~~~~~~~~~~~~
+
+You can allocate a record for the substream and store it in
+``runtime->private_data``. Usually, this is done in the `PCM open
+callback`_. Don't mix this with ``pcm->private_data``. The
+``pcm->private_data`` usually points to the chip instance assigned
+statically at the creation of PCM, while the ``runtime->private_data``
+points to a dynamic data structure created at the PCM open
+callback.
+
+::
+
+  static int snd_xxx_open(struct snd_pcm_substream *substream)
+  {
+          struct my_pcm_data *data;
+          ....
+          data = kmalloc(sizeof(*data), GFP_KERNEL);
+          substream->runtime->private_data = data;
+          ....
+  }
+
+
+The allocated object must be released in the `close callback`_.
+
+Operators
+---------
+
+OK, now let me give details about each pcm callback (``ops``). In
+general, every callback must return 0 if successful, or a negative
+error number such as ``-EINVAL``. To choose an appropriate error
+number, it is advised to check what value other parts of the kernel
+return when the same kind of request fails.
+
+The callback function takes at least the argument with :c:type:`struct
+snd_pcm_substream <snd_pcm_substream>` pointer. To retrieve the chip
+record from the given substream instance, you can use the following
+macro.
+
+::
+
+  int xxx() {
+          struct mychip *chip = snd_pcm_substream_chip(substream);
+          ....
+  }
+
+The macro reads ``substream->private_data``, which is a copy of
+``pcm->private_data``. You can override the former if you need to
+assign different data records per PCM substream. For example, the
+cmi8330 driver assigns different ``private_data`` for playback and
+capture directions, because it uses two different codecs (SB- and
+AD-compatible) for different directions.
+
+PCM open callback
+~~~~~~~~~~~~~~~~~
+
+::
+
+  static int snd_xxx_open(struct snd_pcm_substream *substream);
+
+This is called when a pcm substream is opened.
+
+At least, here you have to initialize the ``runtime->hw``
+record. Typically, this is done by like this:
+
+::
+
+  static int snd_xxx_open(struct snd_pcm_substream *substream)
+  {
+          struct mychip *chip = snd_pcm_substream_chip(substream);
+          struct snd_pcm_runtime *runtime = substream->runtime;
+
+          runtime->hw = snd_mychip_playback_hw;
+          return 0;
+  }
+
+where ``snd_mychip_playback_hw`` is the pre-defined hardware
+description.
+
+You can allocate a private data in this callback, as described in
+`Private Data`_ section.
+
+If the hardware configuration needs more constraints, set the hardware
+constraints here, too. See Constraints_ for more details.
+
+close callback
+~~~~~~~~~~~~~~
+
+::
+
+  static int snd_xxx_close(struct snd_pcm_substream *substream);
+
+
+Obviously, this is called when a pcm substream is closed.
+
+Any private instance for a pcm substream allocated in the ``open``
+callback will be released here.
+
+::
+
+  static int snd_xxx_close(struct snd_pcm_substream *substream)
+  {
+          ....
+          kfree(substream->runtime->private_data);
+          ....
+  }
+
+ioctl callback
+~~~~~~~~~~~~~~
+
+This is used for any special call to pcm ioctls. But usually you can
+pass a generic ioctl callback, :c:func:`snd_pcm_lib_ioctl()`.
+
+hw_params callback
+~~~~~~~~~~~~~~~~~~~
+
+::
+
+  static int snd_xxx_hw_params(struct snd_pcm_substream *substream,
+                               struct snd_pcm_hw_params *hw_params);
+
+This is called when the hardware parameter (``hw_params``) is set up
+by the application, that is, once when the buffer size, the period
+size, the format, etc. are defined for the pcm substream.
+
+Many hardware setups should be done in this callback, including the
+allocation of buffers.
+
+Parameters to be initialized are retrieved by
+:c:func:`params_xxx()` macros. To allocate buffer, you can call a
+helper function,
+
+::
+
+  snd_pcm_lib_malloc_pages(substream, params_buffer_bytes(hw_params));
+
+:c:func:`snd_pcm_lib_malloc_pages()` is available only when the
+DMA buffers have been pre-allocated. See the section `Buffer Types`_
+for more details.
+
+Note that this and ``prepare`` callbacks may be called multiple times
+per initialization. For example, the OSS emulation may call these
+callbacks at each change via its ioctl.
+
+Thus, you need to be careful not to allocate the same buffers many
+times, which will lead to memory leaks! Calling the helper function
+above many times is OK. It will release the previous buffer
+automatically when it was already allocated.
+
+Another note is that this callback is non-atomic (schedulable) as
+default, i.e. when no ``nonatomic`` flag set. This is important,
+because the ``trigger`` callback is atomic (non-schedulable). That is,
+mutexes or any schedule-related functions are not available in
+``trigger`` callback. Please see the subsection Atomicity_ for
+details.
+
+hw_free callback
+~~~~~~~~~~~~~~~~~
+
+::
+
+  static int snd_xxx_hw_free(struct snd_pcm_substream *substream);
+
+This is called to release the resources allocated via
+``hw_params``. For example, releasing the buffer via
+:c:func:`snd_pcm_lib_malloc_pages()` is done by calling the
+following:
+
+::
+
+  snd_pcm_lib_free_pages(substream);
+
+This function is always called before the close callback is called.
+Also, the callback may be called multiple times, too. Keep track
+whether the resource was already released.
+
+prepare callback
+~~~~~~~~~~~~~~~~
+
+::
+
+  static int snd_xxx_prepare(struct snd_pcm_substream *substream);
+
+This callback is called when the pcm is “prepared”. You can set the
+format type, sample rate, etc. here. The difference from ``hw_params``
+is that the ``prepare`` callback will be called each time
+:c:func:`snd_pcm_prepare()` is called, i.e. when recovering after
+underruns, etc.
+
+Note that this callback is now non-atomic. You can use
+schedule-related functions safely in this callback.
+
+In this and the following callbacks, you can refer to the values via
+the runtime record, ``substream->runtime``. For example, to get the
+current rate, format or channels, access to ``runtime->rate``,
+``runtime->format`` or ``runtime->channels``, respectively. The
+physical address of the allocated buffer is set to
+``runtime->dma_area``. The buffer and period sizes are in
+``runtime->buffer_size`` and ``runtime->period_size``, respectively.
+
+Be careful that this callback will be called many times at each setup,
+too.
+
+trigger callback
+~~~~~~~~~~~~~~~~
+
+::
+
+  static int snd_xxx_trigger(struct snd_pcm_substream *substream, int cmd);
+
+This is called when the pcm is started, stopped or paused.
+
+Which action is specified in the second argument,
+``SNDRV_PCM_TRIGGER_XXX`` in ``<sound/pcm.h>``. At least, the ``START``
+and ``STOP`` commands must be defined in this callback.
+
+::
+
+  switch (cmd) {
+  case SNDRV_PCM_TRIGGER_START:
+          /* do something to start the PCM engine */
+          break;
+  case SNDRV_PCM_TRIGGER_STOP:
+          /* do something to stop the PCM engine */
+          break;
+  default:
+          return -EINVAL;
+  }
+
+When the pcm supports the pause operation (given in the info field of
+the hardware table), the ``PAUSE_PUSH`` and ``PAUSE_RELEASE`` commands
+must be handled here, too. The former is the command to pause the pcm,
+and the latter to restart the pcm again.
+
+When the pcm supports the suspend/resume operation, regardless of full
+or partial suspend/resume support, the ``SUSPEND`` and ``RESUME``
+commands must be handled, too. These commands are issued when the
+power-management status is changed. Obviously, the ``SUSPEND`` and
+``RESUME`` commands suspend and resume the pcm substream, and usually,
+they are identical to the ``STOP`` and ``START`` commands, respectively.
+See the `Power Management`_ section for details.
+
+As mentioned, this callback is atomic as default unless ``nonatomic``
+flag set, and you cannot call functions which may sleep. The
+``trigger`` callback should be as minimal as possible, just really
+triggering the DMA. The other stuff should be initialized
+``hw_params`` and ``prepare`` callbacks properly beforehand.
+
+pointer callback
+~~~~~~~~~~~~~~~~
+
+::
+
+  static snd_pcm_uframes_t snd_xxx_pointer(struct snd_pcm_substream *substream)
+
+This callback is called when the PCM middle layer inquires the current
+hardware position on the buffer. The position must be returned in
+frames, ranging from 0 to ``buffer_size - 1``. 
+
+This is called usually from the buffer-update routine in the pcm
+middle layer, which is invoked when :c:func:`snd_pcm_period_elapsed()`
+is called in the interrupt routine. Then the pcm middle layer updates
+the position and calculates the available space, and wakes up the
+sleeping poll threads, etc.
+
+This callback is also atomic as default.
+
+copy and silence callbacks
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+These callbacks are not mandatory, and can be omitted in most cases.
+These callbacks are used when the hardware buffer cannot be in the
+normal memory space. Some chips have their own buffer on the hardware
+which is not mappable. In such a case, you have to transfer the data
+manually from the memory buffer to the hardware buffer. Or, if the
+buffer is non-contiguous on both physical and virtual memory spaces,
+these callbacks must be defined, too.
+
+If these two callbacks are defined, copy and set-silence operations
+are done by them. The detailed will be described in the later section
+`Buffer and Memory Management`_.
+
+ack callback
+~~~~~~~~~~~~
+
+This callback is also not mandatory. This callback is called when the
+``appl_ptr`` is updated in read or write operations. Some drivers like
+emu10k1-fx and cs46xx need to track the current ``appl_ptr`` for the
+internal buffer, and this callback is useful only for such a purpose.
+
+This callback is atomic as default.
+
+page callback
+~~~~~~~~~~~~~
+
+This callback is optional too. This callback is used mainly for
+non-contiguous buffers. The mmap calls this callback to get the page
+address. Some examples will be explained in the later section `Buffer
+and Memory Management`_, too.
+
+PCM Interrupt Handler
+---------------------
+
+The rest of pcm stuff is the PCM interrupt handler. The role of PCM
+interrupt handler in the sound driver is to update the buffer position
+and to tell the PCM middle layer when the buffer position goes across
+the prescribed period size. To inform this, call the
+:c:func:`snd_pcm_period_elapsed()` function.
+
+There are several types of sound chips to generate the interrupts.
+
+Interrupts at the period (fragment) boundary
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This is the most frequently found type: the hardware generates an
+interrupt at each period boundary. In this case, you can call
+:c:func:`snd_pcm_period_elapsed()` at each interrupt.
+
+:c:func:`snd_pcm_period_elapsed()` takes the substream pointer as
+its argument. Thus, you need to keep the substream pointer accessible
+from the chip instance. For example, define ``substream`` field in the
+chip record to hold the current running substream pointer, and set the
+pointer value at ``open`` callback (and reset at ``close`` callback).
+
+If you acquire a spinlock in the interrupt handler, and the lock is used
+in other pcm callbacks, too, then you have to release the lock before
+calling :c:func:`snd_pcm_period_elapsed()`, because
+:c:func:`snd_pcm_period_elapsed()` calls other pcm callbacks
+inside.
+
+Typical code would be like:
+
+::
+
+
+      static irqreturn_t snd_mychip_interrupt(int irq, void *dev_id)
+      {
+              struct mychip *chip = dev_id;
+              spin_lock(&chip->lock);
+              ....
+              if (pcm_irq_invoked(chip)) {
+                      /* call updater, unlock before it */
+                      spin_unlock(&chip->lock);
+                      snd_pcm_period_elapsed(chip->substream);
+                      spin_lock(&chip->lock);
+                      /* acknowledge the interrupt if necessary */
+              }
+              ....
+              spin_unlock(&chip->lock);
+              return IRQ_HANDLED;
+      }
+
+
+
+High frequency timer interrupts
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This happens when the hardware doesn't generate interrupts at the period
+boundary but issues timer interrupts at a fixed timer rate (e.g. es1968
+or ymfpci drivers). In this case, you need to check the current hardware
+position and accumulate the processed sample length at each interrupt.
+When the accumulated size exceeds the period size, call
+:c:func:`snd_pcm_period_elapsed()` and reset the accumulator.
+
+Typical code would be like the following.
+
+::
+
+
+      static irqreturn_t snd_mychip_interrupt(int irq, void *dev_id)
+      {
+              struct mychip *chip = dev_id;
+              spin_lock(&chip->lock);
+              ....
+              if (pcm_irq_invoked(chip)) {
+                      unsigned int last_ptr, size;
+                      /* get the current hardware pointer (in frames) */
+                      last_ptr = get_hw_ptr(chip);
+                      /* calculate the processed frames since the
+                       * last update
+                       */
+                      if (last_ptr < chip->last_ptr)
+                              size = runtime->buffer_size + last_ptr
+                                       - chip->last_ptr;
+                      else
+                              size = last_ptr - chip->last_ptr;
+                      /* remember the last updated point */
+                      chip->last_ptr = last_ptr;
+                      /* accumulate the size */
+                      chip->size += size;
+                      /* over the period boundary? */
+                      if (chip->size >= runtime->period_size) {
+                              /* reset the accumulator */
+                              chip->size %= runtime->period_size;
+                              /* call updater */
+                              spin_unlock(&chip->lock);
+                              snd_pcm_period_elapsed(substream);
+                              spin_lock(&chip->lock);
+                      }
+                      /* acknowledge the interrupt if necessary */
+              }
+              ....
+              spin_unlock(&chip->lock);
+              return IRQ_HANDLED;
+      }
+
+
+
+On calling :c:func:`snd_pcm_period_elapsed()`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In both cases, even if more than one period are elapsed, you don't have
+to call :c:func:`snd_pcm_period_elapsed()` many times. Call only
+once. And the pcm layer will check the current hardware pointer and
+update to the latest status.
+
+Atomicity
+---------
+
+One of the most important (and thus difficult to debug) problems in
+kernel programming are race conditions. In the Linux kernel, they are
+usually avoided via spin-locks, mutexes or semaphores. In general, if a
+race condition can happen in an interrupt handler, it has to be managed
+atomically, and you have to use a spinlock to protect the critical
+session. If the critical section is not in interrupt handler code and if
+taking a relatively long time to execute is acceptable, you should use
+mutexes or semaphores instead.
+
+As already seen, some pcm callbacks are atomic and some are not. For
+example, the ``hw_params`` callback is non-atomic, while ``trigger``
+callback is atomic. This means, the latter is called already in a
+spinlock held by the PCM middle layer. Please take this atomicity into
+account when you choose a locking scheme in the callbacks.
+
+In the atomic callbacks, you cannot use functions which may call
+:c:func:`schedule()` or go to :c:func:`sleep()`. Semaphores and
+mutexes can sleep, and hence they cannot be used inside the atomic
+callbacks (e.g. ``trigger`` callback). To implement some delay in such a
+callback, please use :c:func:`udelay()` or :c:func:`mdelay()`.
+
+All three atomic callbacks (trigger, pointer, and ack) are called with
+local interrupts disabled.
+
+The recent changes in PCM core code, however, allow all PCM operations
+to be non-atomic. This assumes that the all caller sides are in
+non-atomic contexts. For example, the function
+:c:func:`snd_pcm_period_elapsed()` is called typically from the
+interrupt handler. But, if you set up the driver to use a threaded
+interrupt handler, this call can be in non-atomic context, too. In such
+a case, you can set ``nonatomic`` filed of :c:type:`struct snd_pcm
+<snd_pcm>` object after creating it. When this flag is set, mutex
+and rwsem are used internally in the PCM core instead of spin and
+rwlocks, so that you can call all PCM functions safely in a non-atomic
+context.
+
+Constraints
+-----------
+
+If your chip supports unconventional sample rates, or only the limited
+samples, you need to set a constraint for the condition.
+
+For example, in order to restrict the sample rates in the some supported
+values, use :c:func:`snd_pcm_hw_constraint_list()`. You need to
+call this function in the open callback.
+
+::
+
+      static unsigned int rates[] =
+              {4000, 10000, 22050, 44100};
+      static struct snd_pcm_hw_constraint_list constraints_rates = {
+              .count = ARRAY_SIZE(rates),
+              .list = rates,
+              .mask = 0,
+      };
+
+      static int snd_mychip_pcm_open(struct snd_pcm_substream *substream)
+      {
+              int err;
+              ....
+              err = snd_pcm_hw_constraint_list(substream->runtime, 0,
+                                               SNDRV_PCM_HW_PARAM_RATE,
+                                               &constraints_rates);
+              if (err < 0)
+                      return err;
+              ....
+      }
+
+
+
+There are many different constraints. Look at ``sound/pcm.h`` for a
+complete list. You can even define your own constraint rules. For
+example, let's suppose my_chip can manage a substream of 1 channel if
+and only if the format is ``S16_LE``, otherwise it supports any format
+specified in the :c:type:`struct snd_pcm_hardware
+<snd_pcm_hardware>` structure (or in any other
+constraint_list). You can build a rule like this:
+
+::
+
+      static int hw_rule_channels_by_format(struct snd_pcm_hw_params *params,
+                                            struct snd_pcm_hw_rule *rule)
+      {
+              struct snd_interval *c = hw_param_interval(params,
+                            SNDRV_PCM_HW_PARAM_CHANNELS);
+              struct snd_mask *f = hw_param_mask(params, SNDRV_PCM_HW_PARAM_FORMAT);
+              struct snd_interval ch;
+
+              snd_interval_any(&ch);
+              if (f->bits[0] == SNDRV_PCM_FMTBIT_S16_LE) {
+                      ch.min = ch.max = 1;
+                      ch.integer = 1;
+                      return snd_interval_refine(c, &ch);
+              }
+              return 0;
+      }
+
+
+Then you need to call this function to add your rule:
+
+::
+
+  snd_pcm_hw_rule_add(substream->runtime, 0, SNDRV_PCM_HW_PARAM_CHANNELS,
+                      hw_rule_channels_by_format, NULL,
+                      SNDRV_PCM_HW_PARAM_FORMAT, -1);
+
+The rule function is called when an application sets the PCM format, and
+it refines the number of channels accordingly. But an application may
+set the number of channels before setting the format. Thus you also need
+to define the inverse rule:
+
+::
+
+      static int hw_rule_format_by_channels(struct snd_pcm_hw_params *params,
+                                            struct snd_pcm_hw_rule *rule)
+      {
+              struct snd_interval *c = hw_param_interval(params,
+                    SNDRV_PCM_HW_PARAM_CHANNELS);
+              struct snd_mask *f = hw_param_mask(params, SNDRV_PCM_HW_PARAM_FORMAT);
+              struct snd_mask fmt;
+
+              snd_mask_any(&fmt);    /* Init the struct */
+              if (c->min < 2) {
+                      fmt.bits[0] &= SNDRV_PCM_FMTBIT_S16_LE;
+                      return snd_mask_refine(f, &fmt);
+              }
+              return 0;
+      }
+
+
+... and in the open callback:
+
+::
+
+  snd_pcm_hw_rule_add(substream->runtime, 0, SNDRV_PCM_HW_PARAM_FORMAT,
+                      hw_rule_format_by_channels, NULL,
+                      SNDRV_PCM_HW_PARAM_CHANNELS, -1);
+
+I won't give more details here, rather I would like to say, “Luke, use
+the source.”
+
+Control Interface
+=================
+
+General
+-------
+
+The control interface is used widely for many switches, sliders, etc.
+which are accessed from user-space. Its most important use is the mixer
+interface. In other words, since ALSA 0.9.x, all the mixer stuff is
+implemented on the control kernel API.
+
+ALSA has a well-defined AC97 control module. If your chip supports only
+the AC97 and nothing else, you can skip this section.
+
+The control API is defined in ``<sound/control.h>``. Include this file
+if you want to add your own controls.
+
+Definition of Controls
+----------------------
+
+To create a new control, you need to define the following three
+callbacks: ``info``, ``get`` and ``put``. Then, define a
+:c:type:`struct snd_kcontrol_new <snd_kcontrol_new>` record, such as:
+
+::
+
+
+      static struct snd_kcontrol_new my_control = {
+              .iface = SNDRV_CTL_ELEM_IFACE_MIXER,
+              .name = "PCM Playback Switch",
+              .index = 0,
+              .access = SNDRV_CTL_ELEM_ACCESS_READWRITE,
+              .private_value = 0xffff,
+              .info = my_control_info,
+              .get = my_control_get,
+              .put = my_control_put
+      };
+
+
+The ``iface`` field specifies the control type,
+``SNDRV_CTL_ELEM_IFACE_XXX``, which is usually ``MIXER``. Use ``CARD``
+for global controls that are not logically part of the mixer. If the
+control is closely associated with some specific device on the sound
+card, use ``HWDEP``, ``PCM``, ``RAWMIDI``, ``TIMER``, or ``SEQUENCER``,
+and specify the device number with the ``device`` and ``subdevice``
+fields.
+
+The ``name`` is the name identifier string. Since ALSA 0.9.x, the
+control name is very important, because its role is classified from
+its name. There are pre-defined standard control names. The details
+are described in the `Control Names`_ subsection.
+
+The ``index`` field holds the index number of this control. If there
+are several different controls with the same name, they can be
+distinguished by the index number. This is the case when several
+codecs exist on the card. If the index is zero, you can omit the
+definition above. 
+
+The ``access`` field contains the access type of this control. Give
+the combination of bit masks, ``SNDRV_CTL_ELEM_ACCESS_XXX``,
+there. The details will be explained in the `Access Flags`_
+subsection.
+
+The ``private_value`` field contains an arbitrary long integer value
+for this record. When using the generic ``info``, ``get`` and ``put``
+callbacks, you can pass a value through this field. If several small
+numbers are necessary, you can combine them in bitwise. Or, it's
+possible to give a pointer (casted to unsigned long) of some record to
+this field, too. 
+
+The ``tlv`` field can be used to provide metadata about the control;
+see the `Metadata`_ subsection.
+
+The other three are `Control Callbacks`_.
+
+Control Names
+-------------
+
+There are some standards to define the control names. A control is
+usually defined from the three parts as “SOURCE DIRECTION FUNCTION”.
+
+The first, ``SOURCE``, specifies the source of the control, and is a
+string such as “Master”, “PCM”, “CD” and “Line”. There are many
+pre-defined sources.
+
+The second, ``DIRECTION``, is one of the following strings according to
+the direction of the control: “Playback”, “Capture”, “Bypass Playback”
+and “Bypass Capture”. Or, it can be omitted, meaning both playback and
+capture directions.
+
+The third, ``FUNCTION``, is one of the following strings according to
+the function of the control: “Switch”, “Volume” and “Route”.
+
+The example of control names are, thus, “Master Capture Switch” or “PCM
+Playback Volume”.
+
+There are some exceptions:
+
+Global capture and playback
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+“Capture Source”, “Capture Switch” and “Capture Volume” are used for the
+global capture (input) source, switch and volume. Similarly, “Playback
+Switch” and “Playback Volume” are used for the global output gain switch
+and volume.
+
+Tone-controls
+~~~~~~~~~~~~~
+
+tone-control switch and volumes are specified like “Tone Control - XXX”,
+e.g. “Tone Control - Switch”, “Tone Control - Bass”, “Tone Control -
+Center”.
+
+3D controls
+~~~~~~~~~~~
+
+3D-control switches and volumes are specified like “3D Control - XXX”,
+e.g. “3D Control - Switch”, “3D Control - Center”, “3D Control - Space”.
+
+Mic boost
+~~~~~~~~~
+
+Mic-boost switch is set as “Mic Boost” or “Mic Boost (6dB)”.
+
+More precise information can be found in
+``Documentation/sound/alsa/ControlNames.txt``.
+
+Access Flags
+------------
+
+The access flag is the bitmask which specifies the access type of the
+given control. The default access type is
+``SNDRV_CTL_ELEM_ACCESS_READWRITE``, which means both read and write are
+allowed to this control. When the access flag is omitted (i.e. = 0), it
+is considered as ``READWRITE`` access as default.
+
+When the control is read-only, pass ``SNDRV_CTL_ELEM_ACCESS_READ``
+instead. In this case, you don't have to define the ``put`` callback.
+Similarly, when the control is write-only (although it's a rare case),
+you can use the ``WRITE`` flag instead, and you don't need the ``get``
+callback.
+
+If the control value changes frequently (e.g. the VU meter),
+``VOLATILE`` flag should be given. This means that the control may be
+changed without `Change notification`_. Applications should poll such
+a control constantly.
+
+When the control is inactive, set the ``INACTIVE`` flag, too. There are
+``LOCK`` and ``OWNER`` flags to change the write permissions.
+
+Control Callbacks
+-----------------
+
+info callback
+~~~~~~~~~~~~~
+
+The ``info`` callback is used to get detailed information on this
+control. This must store the values of the given :c:type:`struct
+snd_ctl_elem_info <snd_ctl_elem_info>` object. For example,
+for a boolean control with a single element:
+
+::
+
+
+      static int snd_myctl_mono_info(struct snd_kcontrol *kcontrol,
+                              struct snd_ctl_elem_info *uinfo)
+      {
+              uinfo->type = SNDRV_CTL_ELEM_TYPE_BOOLEAN;
+              uinfo->count = 1;
+              uinfo->value.integer.min = 0;
+              uinfo->value.integer.max = 1;
+              return 0;
+      }
+
+
+
+The ``type`` field specifies the type of the control. There are
+``BOOLEAN``, ``INTEGER``, ``ENUMERATED``, ``BYTES``, ``IEC958`` and
+``INTEGER64``. The ``count`` field specifies the number of elements in
+this control. For example, a stereo volume would have count = 2. The
+``value`` field is a union, and the values stored are depending on the
+type. The boolean and integer types are identical.
+
+The enumerated type is a bit different from others. You'll need to set
+the string for the currently given item index.
+
+::
+
+  static int snd_myctl_enum_info(struct snd_kcontrol *kcontrol,
+                          struct snd_ctl_elem_info *uinfo)
+  {
+          static char *texts[4] = {
+                  "First", "Second", "Third", "Fourth"
+          };
+          uinfo->type = SNDRV_CTL_ELEM_TYPE_ENUMERATED;
+          uinfo->count = 1;
+          uinfo->value.enumerated.items = 4;
+          if (uinfo->value.enumerated.item > 3)
+                  uinfo->value.enumerated.item = 3;
+          strcpy(uinfo->value.enumerated.name,
+                 texts[uinfo->value.enumerated.item]);
+          return 0;
+  }
+
+The above callback can be simplified with a helper function,
+:c:func:`snd_ctl_enum_info()`. The final code looks like below.
+(You can pass ``ARRAY_SIZE(texts)`` instead of 4 in the third argument;
+it's a matter of taste.)
+
+::
+
+  static int snd_myctl_enum_info(struct snd_kcontrol *kcontrol,
+                          struct snd_ctl_elem_info *uinfo)
+  {
+          static char *texts[4] = {
+                  "First", "Second", "Third", "Fourth"
+          };
+          return snd_ctl_enum_info(uinfo, 1, 4, texts);
+  }
+
+
+Some common info callbacks are available for your convenience:
+:c:func:`snd_ctl_boolean_mono_info()` and
+:c:func:`snd_ctl_boolean_stereo_info()`. Obviously, the former
+is an info callback for a mono channel boolean item, just like
+:c:func:`snd_myctl_mono_info()` above, and the latter is for a
+stereo channel boolean item.
+
+get callback
+~~~~~~~~~~~~
+
+This callback is used to read the current value of the control and to
+return to user-space.
+
+For example,
+
+::
+
+
+      static int snd_myctl_get(struct snd_kcontrol *kcontrol,
+                               struct snd_ctl_elem_value *ucontrol)
+      {
+              struct mychip *chip = snd_kcontrol_chip(kcontrol);
+              ucontrol->value.integer.value[0] = get_some_value(chip);
+              return 0;
+      }
+
+
+
+The ``value`` field depends on the type of control as well as on the
+info callback. For example, the sb driver uses this field to store the
+register offset, the bit-shift and the bit-mask. The ``private_value``
+field is set as follows:
+
+::
+
+  .private_value = reg | (shift << 16) | (mask << 24)
+
+and is retrieved in callbacks like
+
+::
+
+  static int snd_sbmixer_get_single(struct snd_kcontrol *kcontrol,
+                                    struct snd_ctl_elem_value *ucontrol)
+  {
+          int reg = kcontrol->private_value & 0xff;
+          int shift = (kcontrol->private_value >> 16) & 0xff;
+          int mask = (kcontrol->private_value >> 24) & 0xff;
+          ....
+  }
+
+In the ``get`` callback, you have to fill all the elements if the
+control has more than one elements, i.e. ``count > 1``. In the example
+above, we filled only one element (``value.integer.value[0]``) since
+it's assumed as ``count = 1``.
+
+put callback
+~~~~~~~~~~~~
+
+This callback is used to write a value from user-space.
+
+For example,
+
+::
+
+
+      static int snd_myctl_put(struct snd_kcontrol *kcontrol,
+                               struct snd_ctl_elem_value *ucontrol)
+      {
+              struct mychip *chip = snd_kcontrol_chip(kcontrol);
+              int changed = 0;
+              if (chip->current_value !=
+                   ucontrol->value.integer.value[0]) {
+                      change_current_value(chip,
+                                  ucontrol->value.integer.value[0]);
+                      changed = 1;
+              }
+              return changed;
+      }
+
+
+
+As seen above, you have to return 1 if the value is changed. If the
+value is not changed, return 0 instead. If any fatal error happens,
+return a negative error code as usual.
+
+As in the ``get`` callback, when the control has more than one
+elements, all elements must be evaluated in this callback, too.
+
+Callbacks are not atomic
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+All these three callbacks are basically not atomic.
+
+Control Constructor
+-------------------
+
+When everything is ready, finally we can create a new control. To create
+a control, there are two functions to be called,
+:c:func:`snd_ctl_new1()` and :c:func:`snd_ctl_add()`.
+
+In the simplest way, you can do like this:
+
+::
+
+  err = snd_ctl_add(card, snd_ctl_new1(&my_control, chip));
+  if (err < 0)
+          return err;
+
+where ``my_control`` is the :c:type:`struct snd_kcontrol_new
+<snd_kcontrol_new>` object defined above, and chip is the object
+pointer to be passed to kcontrol->private_data which can be referred
+to in callbacks.
+
+:c:func:`snd_ctl_new1()` allocates a new :c:type:`struct
+snd_kcontrol <snd_kcontrol>` instance, and
+:c:func:`snd_ctl_add()` assigns the given control component to the
+card.
+
+Change Notification
+-------------------
+
+If you need to change and update a control in the interrupt routine, you
+can call :c:func:`snd_ctl_notify()`. For example,
+
+::
+
+  snd_ctl_notify(card, SNDRV_CTL_EVENT_MASK_VALUE, id_pointer);
+
+This function takes the card pointer, the event-mask, and the control id
+pointer for the notification. The event-mask specifies the types of
+notification, for example, in the above example, the change of control
+values is notified. The id pointer is the pointer of :c:type:`struct
+snd_ctl_elem_id <snd_ctl_elem_id>` to be notified. You can
+find some examples in ``es1938.c`` or ``es1968.c`` for hardware volume
+interrupts.
+
+Metadata
+--------
+
+To provide information about the dB values of a mixer control, use on of
+the ``DECLARE_TLV_xxx`` macros from ``<sound/tlv.h>`` to define a
+variable containing this information, set the ``tlv.p`` field to point to
+this variable, and include the ``SNDRV_CTL_ELEM_ACCESS_TLV_READ`` flag
+in the ``access`` field; like this:
+
+::
+
+  static DECLARE_TLV_DB_SCALE(db_scale_my_control, -4050, 150, 0);
+
+  static struct snd_kcontrol_new my_control = {
+          ...
+          .access = SNDRV_CTL_ELEM_ACCESS_READWRITE |
+                    SNDRV_CTL_ELEM_ACCESS_TLV_READ,
+          ...
+          .tlv.p = db_scale_my_control,
+  };
+
+
+The :c:func:`DECLARE_TLV_DB_SCALE()` macro defines information
+about a mixer control where each step in the control's value changes the
+dB value by a constant dB amount. The first parameter is the name of the
+variable to be defined. The second parameter is the minimum value, in
+units of 0.01 dB. The third parameter is the step size, in units of 0.01
+dB. Set the fourth parameter to 1 if the minimum value actually mutes
+the control.
+
+The :c:func:`DECLARE_TLV_DB_LINEAR()` macro defines information
+about a mixer control where the control's value affects the output
+linearly. The first parameter is the name of the variable to be defined.
+The second parameter is the minimum value, in units of 0.01 dB. The
+third parameter is the maximum value, in units of 0.01 dB. If the
+minimum value mutes the control, set the second parameter to
+``TLV_DB_GAIN_MUTE``.
+
+API for AC97 Codec
+==================
+
+General
+-------
+
+The ALSA AC97 codec layer is a well-defined one, and you don't have to
+write much code to control it. Only low-level control routines are
+necessary. The AC97 codec API is defined in ``<sound/ac97_codec.h>``.
+
+Full Code Example
+-----------------
+
+::
+
+      struct mychip {
+              ....
+              struct snd_ac97 *ac97;
+              ....
+      };
+
+      static unsigned short snd_mychip_ac97_read(struct snd_ac97 *ac97,
+                                                 unsigned short reg)
+      {
+              struct mychip *chip = ac97->private_data;
+              ....
+              /* read a register value here from the codec */
+              return the_register_value;
+      }
+
+      static void snd_mychip_ac97_write(struct snd_ac97 *ac97,
+                                       unsigned short reg, unsigned short val)
+      {
+              struct mychip *chip = ac97->private_data;
+              ....
+              /* write the given register value to the codec */
+      }
+
+      static int snd_mychip_ac97(struct mychip *chip)
+      {
+              struct snd_ac97_bus *bus;
+              struct snd_ac97_template ac97;
+              int err;
+              static struct snd_ac97_bus_ops ops = {
+                      .write = snd_mychip_ac97_write,
+                      .read = snd_mychip_ac97_read,
+              };
+
+              err = snd_ac97_bus(chip->card, 0, &ops, NULL, &bus);
+              if (err < 0)
+                      return err;
+              memset(&ac97, 0, sizeof(ac97));
+              ac97.private_data = chip;
+              return snd_ac97_mixer(bus, &ac97, &chip->ac97);
+      }
+
+
+AC97 Constructor
+----------------
+
+To create an ac97 instance, first call :c:func:`snd_ac97_bus()`
+with an ``ac97_bus_ops_t`` record with callback functions.
+
+::
+
+  struct snd_ac97_bus *bus;
+  static struct snd_ac97_bus_ops ops = {
+        .write = snd_mychip_ac97_write,
+        .read = snd_mychip_ac97_read,
+  };
+
+  snd_ac97_bus(card, 0, &ops, NULL, &pbus);
+
+The bus record is shared among all belonging ac97 instances.
+
+And then call :c:func:`snd_ac97_mixer()` with an :c:type:`struct
+snd_ac97_template <snd_ac97_template>` record together with
+the bus pointer created above.
+
+::
+
+  struct snd_ac97_template ac97;
+  int err;
+
+  memset(&ac97, 0, sizeof(ac97));
+  ac97.private_data = chip;
+  snd_ac97_mixer(bus, &ac97, &chip->ac97);
+
+where chip->ac97 is a pointer to a newly created ``ac97_t``
+instance. In this case, the chip pointer is set as the private data,
+so that the read/write callback functions can refer to this chip
+instance. This instance is not necessarily stored in the chip
+record. If you need to change the register values from the driver, or
+need the suspend/resume of ac97 codecs, keep this pointer to pass to
+the corresponding functions.
+
+AC97 Callbacks
+--------------
+
+The standard callbacks are ``read`` and ``write``. Obviously they
+correspond to the functions for read and write accesses to the
+hardware low-level codes.
+
+The ``read`` callback returns the register value specified in the
+argument.
+
+::
+
+  static unsigned short snd_mychip_ac97_read(struct snd_ac97 *ac97,
+                                             unsigned short reg)
+  {
+          struct mychip *chip = ac97->private_data;
+          ....
+          return the_register_value;
+  }
+
+Here, the chip can be cast from ``ac97->private_data``.
+
+Meanwhile, the ``write`` callback is used to set the register
+value
+
+::
+
+  static void snd_mychip_ac97_write(struct snd_ac97 *ac97,
+                       unsigned short reg, unsigned short val)
+
+
+These callbacks are non-atomic like the control API callbacks.
+
+There are also other callbacks: ``reset``, ``wait`` and ``init``.
+
+The ``reset`` callback is used to reset the codec. If the chip
+requires a special kind of reset, you can define this callback.
+
+The ``wait`` callback is used to add some waiting time in the standard
+initialization of the codec. If the chip requires the extra waiting
+time, define this callback.
+
+The ``init`` callback is used for additional initialization of the
+codec.
+
+Updating Registers in The Driver
+--------------------------------
+
+If you need to access to the codec from the driver, you can call the
+following functions: :c:func:`snd_ac97_write()`,
+:c:func:`snd_ac97_read()`, :c:func:`snd_ac97_update()` and
+:c:func:`snd_ac97_update_bits()`.
+
+Both :c:func:`snd_ac97_write()` and
+:c:func:`snd_ac97_update()` functions are used to set a value to
+the given register (``AC97_XXX``). The difference between them is that
+:c:func:`snd_ac97_update()` doesn't write a value if the given
+value has been already set, while :c:func:`snd_ac97_write()`
+always rewrites the value.
+
+::
+
+  snd_ac97_write(ac97, AC97_MASTER, 0x8080);
+  snd_ac97_update(ac97, AC97_MASTER, 0x8080);
+
+:c:func:`snd_ac97_read()` is used to read the value of the given
+register. For example,
+
+::
+
+  value = snd_ac97_read(ac97, AC97_MASTER);
+
+:c:func:`snd_ac97_update_bits()` is used to update some bits in
+the given register.
+
+::
+
+  snd_ac97_update_bits(ac97, reg, mask, value);
+
+Also, there is a function to change the sample rate (of a given register
+such as ``AC97_PCM_FRONT_DAC_RATE``) when VRA or DRA is supported by the
+codec: :c:func:`snd_ac97_set_rate()`.
+
+::
+
+  snd_ac97_set_rate(ac97, AC97_PCM_FRONT_DAC_RATE, 44100);
+
+
+The following registers are available to set the rate:
+``AC97_PCM_MIC_ADC_RATE``, ``AC97_PCM_FRONT_DAC_RATE``,
+``AC97_PCM_LR_ADC_RATE``, ``AC97_SPDIF``. When ``AC97_SPDIF`` is
+specified, the register is not really changed but the corresponding
+IEC958 status bits will be updated.
+
+Clock Adjustment
+----------------
+
+In some chips, the clock of the codec isn't 48000 but using a PCI clock
+(to save a quartz!). In this case, change the field ``bus->clock`` to
+the corresponding value. For example, intel8x0 and es1968 drivers have
+their own function to read from the clock.
+
+Proc Files
+----------
+
+The ALSA AC97 interface will create a proc file such as
+``/proc/asound/card0/codec97#0/ac97#0-0`` and ``ac97#0-0+regs``. You
+can refer to these files to see the current status and registers of
+the codec.
+
+Multiple Codecs
+---------------
+
+When there are several codecs on the same card, you need to call
+:c:func:`snd_ac97_mixer()` multiple times with ``ac97.num=1`` or
+greater. The ``num`` field specifies the codec number.
+
+If you set up multiple codecs, you either need to write different
+callbacks for each codec or check ``ac97->num`` in the callback
+routines.
+
+MIDI (MPU401-UART) Interface
+============================
+
+General
+-------
+
+Many soundcards have built-in MIDI (MPU401-UART) interfaces. When the
+soundcard supports the standard MPU401-UART interface, most likely you
+can use the ALSA MPU401-UART API. The MPU401-UART API is defined in
+``<sound/mpu401.h>``.
+
+Some soundchips have a similar but slightly different implementation of
+mpu401 stuff. For example, emu10k1 has its own mpu401 routines.
+
+MIDI Constructor
+----------------
+
+To create a rawmidi object, call :c:func:`snd_mpu401_uart_new()`.
+
+::
+
+  struct snd_rawmidi *rmidi;
+  snd_mpu401_uart_new(card, 0, MPU401_HW_MPU401, port, info_flags,
+                      irq, &rmidi);
+
+
+The first argument is the card pointer, and the second is the index of
+this component. You can create up to 8 rawmidi devices.
+
+The third argument is the type of the hardware, ``MPU401_HW_XXX``. If
+it's not a special one, you can use ``MPU401_HW_MPU401``.
+
+The 4th argument is the I/O port address. Many backward-compatible
+MPU401 have an I/O port such as 0x330. Or, it might be a part of its own
+PCI I/O region. It depends on the chip design.
+
+The 5th argument is a bitflag for additional information. When the I/O
+port address above is part of the PCI I/O region, the MPU401 I/O port
+might have been already allocated (reserved) by the driver itself. In
+such a case, pass a bit flag ``MPU401_INFO_INTEGRATED``, and the
+mpu401-uart layer will allocate the I/O ports by itself.
+
+When the controller supports only the input or output MIDI stream, pass
+the ``MPU401_INFO_INPUT`` or ``MPU401_INFO_OUTPUT`` bitflag,
+respectively. Then the rawmidi instance is created as a single stream.
+
+``MPU401_INFO_MMIO`` bitflag is used to change the access method to MMIO
+(via readb and writeb) instead of iob and outb. In this case, you have
+to pass the iomapped address to :c:func:`snd_mpu401_uart_new()`.
+
+When ``MPU401_INFO_TX_IRQ`` is set, the output stream isn't checked in
+the default interrupt handler. The driver needs to call
+:c:func:`snd_mpu401_uart_interrupt_tx()` by itself to start
+processing the output stream in the irq handler.
+
+If the MPU-401 interface shares its interrupt with the other logical
+devices on the card, set ``MPU401_INFO_IRQ_HOOK`` (see
+`below <#MIDI-Interrupt-Handler>`__).
+
+Usually, the port address corresponds to the command port and port + 1
+corresponds to the data port. If not, you may change the ``cport``
+field of :c:type:`struct snd_mpu401 <snd_mpu401>` manually afterward.
+However, :c:type:`struct snd_mpu401 <snd_mpu401>` pointer is
+not returned explicitly by :c:func:`snd_mpu401_uart_new()`. You
+need to cast ``rmidi->private_data`` to :c:type:`struct snd_mpu401
+<snd_mpu401>` explicitly,
+
+::
+
+  struct snd_mpu401 *mpu;
+  mpu = rmidi->private_data;
+
+and reset the ``cport`` as you like:
+
+::
+
+  mpu->cport = my_own_control_port;
+
+The 6th argument specifies the ISA irq number that will be allocated. If
+no interrupt is to be allocated (because your code is already allocating
+a shared interrupt, or because the device does not use interrupts), pass
+-1 instead. For a MPU-401 device without an interrupt, a polling timer
+will be used instead.
+
+MIDI Interrupt Handler
+----------------------
+
+When the interrupt is allocated in
+:c:func:`snd_mpu401_uart_new()`, an exclusive ISA interrupt
+handler is automatically used, hence you don't have anything else to do
+than creating the mpu401 stuff. Otherwise, you have to set
+``MPU401_INFO_IRQ_HOOK``, and call
+:c:func:`snd_mpu401_uart_interrupt()` explicitly from your own
+interrupt handler when it has determined that a UART interrupt has
+occurred.
+
+In this case, you need to pass the private_data of the returned rawmidi
+object from :c:func:`snd_mpu401_uart_new()` as the second
+argument of :c:func:`snd_mpu401_uart_interrupt()`.
+
+::
+
+  snd_mpu401_uart_interrupt(irq, rmidi->private_data, regs);
+
+
+RawMIDI Interface
+=================
+
+Overview
+--------
+
+The raw MIDI interface is used for hardware MIDI ports that can be
+accessed as a byte stream. It is not used for synthesizer chips that do
+not directly understand MIDI.
+
+ALSA handles file and buffer management. All you have to do is to write
+some code to move data between the buffer and the hardware.
+
+The rawmidi API is defined in ``<sound/rawmidi.h>``.
+
+RawMIDI Constructor
+-------------------
+
+To create a rawmidi device, call the :c:func:`snd_rawmidi_new()`
+function:
+
+::
+
+  struct snd_rawmidi *rmidi;
+  err = snd_rawmidi_new(chip->card, "MyMIDI", 0, outs, ins, &rmidi);
+  if (err < 0)
+          return err;
+  rmidi->private_data = chip;
+  strcpy(rmidi->name, "My MIDI");
+  rmidi->info_flags = SNDRV_RAWMIDI_INFO_OUTPUT |
+                      SNDRV_RAWMIDI_INFO_INPUT |
+                      SNDRV_RAWMIDI_INFO_DUPLEX;
+
+The first argument is the card pointer, the second argument is the ID
+string.
+
+The third argument is the index of this component. You can create up to
+8 rawmidi devices.
+
+The fourth and fifth arguments are the number of output and input
+substreams, respectively, of this device (a substream is the equivalent
+of a MIDI port).
+
+Set the ``info_flags`` field to specify the capabilities of the
+device. Set ``SNDRV_RAWMIDI_INFO_OUTPUT`` if there is at least one
+output port, ``SNDRV_RAWMIDI_INFO_INPUT`` if there is at least one
+input port, and ``SNDRV_RAWMIDI_INFO_DUPLEX`` if the device can handle
+output and input at the same time.
+
+After the rawmidi device is created, you need to set the operators
+(callbacks) for each substream. There are helper functions to set the
+operators for all the substreams of a device:
+
+::
+
+  snd_rawmidi_set_ops(rmidi, SNDRV_RAWMIDI_STREAM_OUTPUT, &snd_mymidi_output_ops);
+  snd_rawmidi_set_ops(rmidi, SNDRV_RAWMIDI_STREAM_INPUT, &snd_mymidi_input_ops);
+
+The operators are usually defined like this:
+
+::
+
+  static struct snd_rawmidi_ops snd_mymidi_output_ops = {
+          .open =    snd_mymidi_output_open,
+          .close =   snd_mymidi_output_close,
+          .trigger = snd_mymidi_output_trigger,
+  };
+
+These callbacks are explained in the `RawMIDI Callbacks`_ section.
+
+If there are more than one substream, you should give a unique name to
+each of them:
+
+::
+
+  struct snd_rawmidi_substream *substream;
+  list_for_each_entry(substream,
+                      &rmidi->streams[SNDRV_RAWMIDI_STREAM_OUTPUT].substreams,
+                      list {
+          sprintf(substream->name, "My MIDI Port %d", substream->number + 1);
+  }
+  /* same for SNDRV_RAWMIDI_STREAM_INPUT */
+
+RawMIDI Callbacks
+-----------------
+
+In all the callbacks, the private data that you've set for the rawmidi
+device can be accessed as ``substream->rmidi->private_data``.
+
+If there is more than one port, your callbacks can determine the port
+index from the struct snd_rawmidi_substream data passed to each
+callback:
+
+::
+
+  struct snd_rawmidi_substream *substream;
+  int index = substream->number;
+
+RawMIDI open callback
+~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+      static int snd_xxx_open(struct snd_rawmidi_substream *substream);
+
+
+This is called when a substream is opened. You can initialize the
+hardware here, but you shouldn't start transmitting/receiving data yet.
+
+RawMIDI close callback
+~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+      static int snd_xxx_close(struct snd_rawmidi_substream *substream);
+
+Guess what.
+
+The ``open`` and ``close`` callbacks of a rawmidi device are
+serialized with a mutex, and can sleep.
+
+Rawmidi trigger callback for output substreams
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+      static void snd_xxx_output_trigger(struct snd_rawmidi_substream *substream, int up);
+
+
+This is called with a nonzero ``up`` parameter when there is some data
+in the substream buffer that must be transmitted.
+
+To read data from the buffer, call
+:c:func:`snd_rawmidi_transmit_peek()`. It will return the number
+of bytes that have been read; this will be less than the number of bytes
+requested when there are no more data in the buffer. After the data have
+been transmitted successfully, call
+:c:func:`snd_rawmidi_transmit_ack()` to remove the data from the
+substream buffer:
+
+::
+
+  unsigned char data;
+  while (snd_rawmidi_transmit_peek(substream, &data, 1) == 1) {
+          if (snd_mychip_try_to_transmit(data))
+                  snd_rawmidi_transmit_ack(substream, 1);
+          else
+                  break; /* hardware FIFO full */
+  }
+
+If you know beforehand that the hardware will accept data, you can use
+the :c:func:`snd_rawmidi_transmit()` function which reads some
+data and removes them from the buffer at once:
+
+::
+
+  while (snd_mychip_transmit_possible()) {
+          unsigned char data;
+          if (snd_rawmidi_transmit(substream, &data, 1) != 1)
+                  break; /* no more data */
+          snd_mychip_transmit(data);
+  }
+
+If you know beforehand how many bytes you can accept, you can use a
+buffer size greater than one with the
+:c:func:`snd_rawmidi_transmit\*()` functions.
+
+The ``trigger`` callback must not sleep. If the hardware FIFO is full
+before the substream buffer has been emptied, you have to continue
+transmitting data later, either in an interrupt handler, or with a
+timer if the hardware doesn't have a MIDI transmit interrupt.
+
+The ``trigger`` callback is called with a zero ``up`` parameter when
+the transmission of data should be aborted.
+
+RawMIDI trigger callback for input substreams
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+::
+
+      static void snd_xxx_input_trigger(struct snd_rawmidi_substream *substream, int up);
+
+
+This is called with a nonzero ``up`` parameter to enable receiving data,
+or with a zero ``up`` parameter do disable receiving data.
+
+The ``trigger`` callback must not sleep; the actual reading of data
+from the device is usually done in an interrupt handler.
+
+When data reception is enabled, your interrupt handler should call
+:c:func:`snd_rawmidi_receive()` for all received data:
+
+::
+
+  void snd_mychip_midi_interrupt(...)
+  {
+          while (mychip_midi_available()) {
+                  unsigned char data;
+                  data = mychip_midi_read();
+                  snd_rawmidi_receive(substream, &data, 1);
+          }
+  }
+
+
+drain callback
+~~~~~~~~~~~~~~
+
+::
+
+      static void snd_xxx_drain(struct snd_rawmidi_substream *substream);
+
+
+This is only used with output substreams. This function should wait
+until all data read from the substream buffer have been transmitted.
+This ensures that the device can be closed and the driver unloaded
+without losing data.
+
+This callback is optional. If you do not set ``drain`` in the struct
+snd_rawmidi_ops structure, ALSA will simply wait for 50 milliseconds
+instead.
+
+Miscellaneous Devices
+=====================
+
+FM OPL3
+-------
+
+The FM OPL3 is still used in many chips (mainly for backward
+compatibility). ALSA has a nice OPL3 FM control layer, too. The OPL3 API
+is defined in ``<sound/opl3.h>``.
+
+FM registers can be directly accessed through the direct-FM API, defined
+in ``<sound/asound_fm.h>``. In ALSA native mode, FM registers are
+accessed through the Hardware-Dependent Device direct-FM extension API,
+whereas in OSS compatible mode, FM registers can be accessed with the
+OSS direct-FM compatible API in ``/dev/dmfmX`` device.
+
+To create the OPL3 component, you have two functions to call. The first
+one is a constructor for the ``opl3_t`` instance.
+
+::
+
+  struct snd_opl3 *opl3;
+  snd_opl3_create(card, lport, rport, OPL3_HW_OPL3_XXX,
+                  integrated, &opl3);
+
+The first argument is the card pointer, the second one is the left port
+address, and the third is the right port address. In most cases, the
+right port is placed at the left port + 2.
+
+The fourth argument is the hardware type.
+
+When the left and right ports have been already allocated by the card
+driver, pass non-zero to the fifth argument (``integrated``). Otherwise,
+the opl3 module will allocate the specified ports by itself.
+
+When the accessing the hardware requires special method instead of the
+standard I/O access, you can create opl3 instance separately with
+:c:func:`snd_opl3_new()`.
+
+::
+
+  struct snd_opl3 *opl3;
+  snd_opl3_new(card, OPL3_HW_OPL3_XXX, &opl3);
+
+Then set ``command``, ``private_data`` and ``private_free`` for the
+private access function, the private data and the destructor. The
+``l_port`` and ``r_port`` are not necessarily set. Only the command
+must be set properly. You can retrieve the data from the
+``opl3->private_data`` field. 
+
+After creating the opl3 instance via :c:func:`snd_opl3_new()`,
+call :c:func:`snd_opl3_init()` to initialize the chip to the
+proper state. Note that :c:func:`snd_opl3_create()` always calls
+it internally.
+
+If the opl3 instance is created successfully, then create a hwdep device
+for this opl3.
+
+::
+
+  struct snd_hwdep *opl3hwdep;
+  snd_opl3_hwdep_new(opl3, 0, 1, &opl3hwdep);
+
+The first argument is the ``opl3_t`` instance you created, and the
+second is the index number, usually 0.
+
+The third argument is the index-offset for the sequencer client assigned
+to the OPL3 port. When there is an MPU401-UART, give 1 for here (UART
+always takes 0).
+
+Hardware-Dependent Devices
+--------------------------
+
+Some chips need user-space access for special controls or for loading
+the micro code. In such a case, you can create a hwdep
+(hardware-dependent) device. The hwdep API is defined in
+``<sound/hwdep.h>``. You can find examples in opl3 driver or
+``isa/sb/sb16_csp.c``.
+
+The creation of the ``hwdep`` instance is done via
+:c:func:`snd_hwdep_new()`.
+
+::
+
+  struct snd_hwdep *hw;
+  snd_hwdep_new(card, "My HWDEP", 0, &hw);
+
+where the third argument is the index number.
+
+You can then pass any pointer value to the ``private_data``. If you
+assign a private data, you should define the destructor, too. The
+destructor function is set in the ``private_free`` field.
+
+::
+
+  struct mydata *p = kmalloc(sizeof(*p), GFP_KERNEL);
+  hw->private_data = p;
+  hw->private_free = mydata_free;
+
+and the implementation of the destructor would be:
+
+::
+
+  static void mydata_free(struct snd_hwdep *hw)
+  {
+          struct mydata *p = hw->private_data;
+          kfree(p);
+  }
+
+The arbitrary file operations can be defined for this instance. The file
+operators are defined in the ``ops`` table. For example, assume that
+this chip needs an ioctl.
+
+::
+
+  hw->ops.open = mydata_open;
+  hw->ops.ioctl = mydata_ioctl;
+  hw->ops.release = mydata_release;
+
+And implement the callback functions as you like.
+
+IEC958 (S/PDIF)
+---------------
+
+Usually the controls for IEC958 devices are implemented via the control
+interface. There is a macro to compose a name string for IEC958
+controls, :c:func:`SNDRV_CTL_NAME_IEC958()` defined in
+``<include/asound.h>``.
+
+There are some standard controls for IEC958 status bits. These controls
+use the type ``SNDRV_CTL_ELEM_TYPE_IEC958``, and the size of element is
+fixed as 4 bytes array (value.iec958.status[x]). For the ``info``
+callback, you don't specify the value field for this type (the count
+field must be set, though).
+
+“IEC958 Playback Con Mask” is used to return the bit-mask for the IEC958
+status bits of consumer mode. Similarly, “IEC958 Playback Pro Mask”
+returns the bitmask for professional mode. They are read-only controls,
+and are defined as MIXER controls (iface =
+``SNDRV_CTL_ELEM_IFACE_MIXER``).
+
+Meanwhile, “IEC958 Playback Default” control is defined for getting and
+setting the current default IEC958 bits. Note that this one is usually
+defined as a PCM control (iface = ``SNDRV_CTL_ELEM_IFACE_PCM``),
+although in some places it's defined as a MIXER control.
+
+In addition, you can define the control switches to enable/disable or to
+set the raw bit mode. The implementation will depend on the chip, but
+the control should be named as “IEC958 xxx”, preferably using the
+:c:func:`SNDRV_CTL_NAME_IEC958()` macro.
+
+You can find several cases, for example, ``pci/emu10k1``,
+``pci/ice1712``, or ``pci/cmipci.c``.
+
+Buffer and Memory Management
+============================
+
+Buffer Types
+------------
+
+ALSA provides several different buffer allocation functions depending on
+the bus and the architecture. All these have a consistent API. The
+allocation of physically-contiguous pages is done via
+:c:func:`snd_malloc_xxx_pages()` function, where xxx is the bus
+type.
+
+The allocation of pages with fallback is
+:c:func:`snd_malloc_xxx_pages_fallback()`. This function tries
+to allocate the specified pages but if the pages are not available, it
+tries to reduce the page sizes until enough space is found.
+
+The release the pages, call :c:func:`snd_free_xxx_pages()`
+function.
+
+Usually, ALSA drivers try to allocate and reserve a large contiguous
+physical space at the time the module is loaded for the later use. This
+is called “pre-allocation”. As already written, you can call the
+following function at pcm instance construction time (in the case of PCI
+bus).
+
+::
+
+  snd_pcm_lib_preallocate_pages_for_all(pcm, SNDRV_DMA_TYPE_DEV,
+                                        snd_dma_pci_data(pci), size, max);
+
+where ``size`` is the byte size to be pre-allocated and the ``max`` is
+the maximum size to be changed via the ``prealloc`` proc file. The
+allocator will try to get an area as large as possible within the
+given size.
+
+The second argument (type) and the third argument (device pointer) are
+dependent on the bus. In the case of the ISA bus, pass
+:c:func:`snd_dma_isa_data()` as the third argument with
+``SNDRV_DMA_TYPE_DEV`` type. For the continuous buffer unrelated to the
+bus can be pre-allocated with ``SNDRV_DMA_TYPE_CONTINUOUS`` type and the
+``snd_dma_continuous_data(GFP_KERNEL)`` device pointer, where
+``GFP_KERNEL`` is the kernel allocation flag to use. For the PCI
+scatter-gather buffers, use ``SNDRV_DMA_TYPE_DEV_SG`` with
+``snd_dma_pci_data(pci)`` (see the `Non-Contiguous Buffers`_
+section).
+
+Once the buffer is pre-allocated, you can use the allocator in the
+``hw_params`` callback:
+
+::
+
+  snd_pcm_lib_malloc_pages(substream, size);
+
+Note that you have to pre-allocate to use this function.
+
+External Hardware Buffers
+-------------------------
+
+Some chips have their own hardware buffers and the DMA transfer from the
+host memory is not available. In such a case, you need to either 1)
+copy/set the audio data directly to the external hardware buffer, or 2)
+make an intermediate buffer and copy/set the data from it to the
+external hardware buffer in interrupts (or in tasklets, preferably).
+
+The first case works fine if the external hardware buffer is large
+enough. This method doesn't need any extra buffers and thus is more
+effective. You need to define the ``copy`` and ``silence`` callbacks
+for the data transfer. However, there is a drawback: it cannot be
+mmapped. The examples are GUS's GF1 PCM or emu8000's wavetable PCM.
+
+The second case allows for mmap on the buffer, although you have to
+handle an interrupt or a tasklet to transfer the data from the
+intermediate buffer to the hardware buffer. You can find an example in
+the vxpocket driver.
+
+Another case is when the chip uses a PCI memory-map region for the
+buffer instead of the host memory. In this case, mmap is available only
+on certain architectures like the Intel one. In non-mmap mode, the data
+cannot be transferred as in the normal way. Thus you need to define the
+``copy`` and ``silence`` callbacks as well, as in the cases above. The
+examples are found in ``rme32.c`` and ``rme96.c``.
+
+The implementation of the ``copy`` and ``silence`` callbacks depends
+upon whether the hardware supports interleaved or non-interleaved
+samples. The ``copy`` callback is defined like below, a bit
+differently depending whether the direction is playback or capture:
+
+::
+
+  static int playback_copy(struct snd_pcm_substream *substream, int channel,
+               snd_pcm_uframes_t pos, void *src, snd_pcm_uframes_t count);
+  static int capture_copy(struct snd_pcm_substream *substream, int channel,
+               snd_pcm_uframes_t pos, void *dst, snd_pcm_uframes_t count);
+
+In the case of interleaved samples, the second argument (``channel``) is
+not used. The third argument (``pos``) points the current position
+offset in frames.
+
+The meaning of the fourth argument is different between playback and
+capture. For playback, it holds the source data pointer, and for
+capture, it's the destination data pointer.
+
+The last argument is the number of frames to be copied.
+
+What you have to do in this callback is again different between playback
+and capture directions. In the playback case, you copy the given amount
+of data (``count``) at the specified pointer (``src``) to the specified
+offset (``pos``) on the hardware buffer. When coded like memcpy-like
+way, the copy would be like:
+
+::
+
+  my_memcpy(my_buffer + frames_to_bytes(runtime, pos), src,
+            frames_to_bytes(runtime, count));
+
+For the capture direction, you copy the given amount of data (``count``)
+at the specified offset (``pos``) on the hardware buffer to the
+specified pointer (``dst``).
+
+::
+
+  my_memcpy(dst, my_buffer + frames_to_bytes(runtime, pos),
+            frames_to_bytes(runtime, count));
+
+Note that both the position and the amount of data are given in frames.
+
+In the case of non-interleaved samples, the implementation will be a bit
+more complicated.
+
+You need to check the channel argument, and if it's -1, copy the whole
+channels. Otherwise, you have to copy only the specified channel. Please
+check ``isa/gus/gus_pcm.c`` as an example.
+
+The ``silence`` callback is also implemented in a similar way
+
+::
+
+  static int silence(struct snd_pcm_substream *substream, int channel,
+                     snd_pcm_uframes_t pos, snd_pcm_uframes_t count);
+
+The meanings of arguments are the same as in the ``copy`` callback,
+although there is no ``src/dst`` argument. In the case of interleaved
+samples, the channel argument has no meaning, as well as on ``copy``
+callback.
+
+The role of ``silence`` callback is to set the given amount
+(``count``) of silence data at the specified offset (``pos``) on the
+hardware buffer. Suppose that the data format is signed (that is, the
+silent-data is 0), and the implementation using a memset-like function
+would be like: 
+
+::
+
+  my_memcpy(my_buffer + frames_to_bytes(runtime, pos), 0,
+            frames_to_bytes(runtime, count));
+
+In the case of non-interleaved samples, again, the implementation
+becomes a bit more complicated. See, for example, ``isa/gus/gus_pcm.c``.
+
+Non-Contiguous Buffers
+----------------------
+
+If your hardware supports the page table as in emu10k1 or the buffer
+descriptors as in via82xx, you can use the scatter-gather (SG) DMA. ALSA
+provides an interface for handling SG-buffers. The API is provided in
+``<sound/pcm.h>``.
+
+For creating the SG-buffer handler, call
+:c:func:`snd_pcm_lib_preallocate_pages()` or
+:c:func:`snd_pcm_lib_preallocate_pages_for_all()` with
+``SNDRV_DMA_TYPE_DEV_SG`` in the PCM constructor like other PCI
+pre-allocator. You need to pass ``snd_dma_pci_data(pci)``, where pci is
+the :c:type:`struct pci_dev <pci_dev>` pointer of the chip as
+well. The ``struct snd_sg_buf`` instance is created as
+``substream->dma_private``. You can cast the pointer like:
+
+::
+
+  struct snd_sg_buf *sgbuf = (struct snd_sg_buf *)substream->dma_private;
+
+Then call :c:func:`snd_pcm_lib_malloc_pages()` in the ``hw_params``
+callback as well as in the case of normal PCI buffer. The SG-buffer
+handler will allocate the non-contiguous kernel pages of the given size
+and map them onto the virtually contiguous memory. The virtual pointer
+is addressed in runtime->dma_area. The physical address
+(``runtime->dma_addr``) is set to zero, because the buffer is
+physically non-contiguous. The physical address table is set up in
+``sgbuf->table``. You can get the physical address at a certain offset
+via :c:func:`snd_pcm_sgbuf_get_addr()`.
+
+When a SG-handler is used, you need to set
+:c:func:`snd_pcm_sgbuf_ops_page()` as the ``page`` callback. (See
+`page callback`_ section.)
+
+To release the data, call :c:func:`snd_pcm_lib_free_pages()` in
+the ``hw_free`` callback as usual.
+
+Vmalloc'ed Buffers
+------------------
+
+It's possible to use a buffer allocated via :c:func:`vmalloc()`, for
+example, for an intermediate buffer. Since the allocated pages are not
+contiguous, you need to set the ``page`` callback to obtain the physical
+address at every offset.
+
+The implementation of ``page`` callback would be like this:
+
+::
+
+  #include <linux/vmalloc.h>
+
+  /* get the physical page pointer on the given offset */
+  static struct page *mychip_page(struct snd_pcm_substream *substream,
+                                  unsigned long offset)
+  {
+          void *pageptr = substream->runtime->dma_area + offset;
+          return vmalloc_to_page(pageptr);
+  }
+
+Proc Interface
+==============
+
+ALSA provides an easy interface for procfs. The proc files are very
+useful for debugging. I recommend you set up proc files if you write a
+driver and want to get a running status or register dumps. The API is
+found in ``<sound/info.h>``.
+
+To create a proc file, call :c:func:`snd_card_proc_new()`.
+
+::
+
+  struct snd_info_entry *entry;
+  int err = snd_card_proc_new(card, "my-file", &entry);
+
+where the second argument specifies the name of the proc file to be
+created. The above example will create a file ``my-file`` under the
+card directory, e.g. ``/proc/asound/card0/my-file``.
+
+Like other components, the proc entry created via
+:c:func:`snd_card_proc_new()` will be registered and released
+automatically in the card registration and release functions.
+
+When the creation is successful, the function stores a new instance in
+the pointer given in the third argument. It is initialized as a text
+proc file for read only. To use this proc file as a read-only text file
+as it is, set the read callback with a private data via
+:c:func:`snd_info_set_text_ops()`.
+
+::
+
+  snd_info_set_text_ops(entry, chip, my_proc_read);
+
+where the second argument (``chip``) is the private data to be used in
+the callbacks. The third parameter specifies the read buffer size and
+the fourth (``my_proc_read``) is the callback function, which is
+defined like
+
+::
+
+  static void my_proc_read(struct snd_info_entry *entry,
+                           struct snd_info_buffer *buffer);
+
+In the read callback, use :c:func:`snd_iprintf()` for output
+strings, which works just like normal :c:func:`printf()`. For
+example,
+
+::
+
+  static void my_proc_read(struct snd_info_entry *entry,
+                           struct snd_info_buffer *buffer)
+  {
+          struct my_chip *chip = entry->private_data;
+
+          snd_iprintf(buffer, "This is my chip!\n");
+          snd_iprintf(buffer, "Port = %ld\n", chip->port);
+  }
+
+The file permissions can be changed afterwards. As default, it's set as
+read only for all users. If you want to add write permission for the
+user (root as default), do as follows:
+
+::
+
+ entry->mode = S_IFREG | S_IRUGO | S_IWUSR;
+
+and set the write buffer size and the callback
+
+::
+
+  entry->c.text.write = my_proc_write;
+
+For the write callback, you can use :c:func:`snd_info_get_line()`
+to get a text line, and :c:func:`snd_info_get_str()` to retrieve
+a string from the line. Some examples are found in
+``core/oss/mixer_oss.c``, core/oss/and ``pcm_oss.c``.
+
+For a raw-data proc-file, set the attributes as follows:
+
+::
+
+  static struct snd_info_entry_ops my_file_io_ops = {
+          .read = my_file_io_read,
+  };
+
+  entry->content = SNDRV_INFO_CONTENT_DATA;
+  entry->private_data = chip;
+  entry->c.ops = &my_file_io_ops;
+  entry->size = 4096;
+  entry->mode = S_IFREG | S_IRUGO;
+
+For the raw data, ``size`` field must be set properly. This specifies
+the maximum size of the proc file access.
+
+The read/write callbacks of raw mode are more direct than the text mode.
+You need to use a low-level I/O functions such as
+:c:func:`copy_from/to_user()` to transfer the data.
+
+::
+
+  static ssize_t my_file_io_read(struct snd_info_entry *entry,
+                              void *file_private_data,
+                              struct file *file,
+                              char *buf,
+                              size_t count,
+                              loff_t pos)
+  {
+          if (copy_to_user(buf, local_data + pos, count))
+                  return -EFAULT;
+          return count;
+  }
+
+If the size of the info entry has been set up properly, ``count`` and
+``pos`` are guaranteed to fit within 0 and the given size. You don't
+have to check the range in the callbacks unless any other condition is
+required.
+
+Power Management
+================
+
+If the chip is supposed to work with suspend/resume functions, you need
+to add power-management code to the driver. The additional code for
+power-management should be ifdef-ed with ``CONFIG_PM``.
+
+If the driver *fully* supports suspend/resume that is, the device can be
+properly resumed to its state when suspend was called, you can set the
+``SNDRV_PCM_INFO_RESUME`` flag in the pcm info field. Usually, this is
+possible when the registers of the chip can be safely saved and restored
+to RAM. If this is set, the trigger callback is called with
+``SNDRV_PCM_TRIGGER_RESUME`` after the resume callback completes.
+
+Even if the driver doesn't support PM fully but partial suspend/resume
+is still possible, it's still worthy to implement suspend/resume
+callbacks. In such a case, applications would reset the status by
+calling :c:func:`snd_pcm_prepare()` and restart the stream
+appropriately. Hence, you can define suspend/resume callbacks below but
+don't set ``SNDRV_PCM_INFO_RESUME`` info flag to the PCM.
+
+Note that the trigger with SUSPEND can always be called when
+:c:func:`snd_pcm_suspend_all()` is called, regardless of the
+``SNDRV_PCM_INFO_RESUME`` flag. The ``RESUME`` flag affects only the
+behavior of :c:func:`snd_pcm_resume()`. (Thus, in theory,
+``SNDRV_PCM_TRIGGER_RESUME`` isn't needed to be handled in the trigger
+callback when no ``SNDRV_PCM_INFO_RESUME`` flag is set. But, it's better
+to keep it for compatibility reasons.)
+
+In the earlier version of ALSA drivers, a common power-management layer
+was provided, but it has been removed. The driver needs to define the
+suspend/resume hooks according to the bus the device is connected to. In
+the case of PCI drivers, the callbacks look like below:
+
+::
+
+  #ifdef CONFIG_PM
+  static int snd_my_suspend(struct pci_dev *pci, pm_message_t state)
+  {
+          .... /* do things for suspend */
+          return 0;
+  }
+  static int snd_my_resume(struct pci_dev *pci)
+  {
+          .... /* do things for suspend */
+          return 0;
+  }
+  #endif
+
+The scheme of the real suspend job is as follows.
+
+1. Retrieve the card and the chip data.
+
+2. Call :c:func:`snd_power_change_state()` with
+   ``SNDRV_CTL_POWER_D3hot`` to change the power status.
+
+3. Call :c:func:`snd_pcm_suspend_all()` to suspend the running
+   PCM streams.
+
+4. If AC97 codecs are used, call :c:func:`snd_ac97_suspend()` for
+   each codec.
+
+5. Save the register values if necessary.
+
+6. Stop the hardware if necessary.
+
+7. Disable the PCI device by calling
+   :c:func:`pci_disable_device()`. Then, call
+   :c:func:`pci_save_state()` at last.
+
+A typical code would be like:
+
+::
+
+  static int mychip_suspend(struct pci_dev *pci, pm_message_t state)
+  {
+          /* (1) */
+          struct snd_card *card = pci_get_drvdata(pci);
+          struct mychip *chip = card->private_data;
+          /* (2) */
+          snd_power_change_state(card, SNDRV_CTL_POWER_D3hot);
+          /* (3) */
+          snd_pcm_suspend_all(chip->pcm);
+          /* (4) */
+          snd_ac97_suspend(chip->ac97);
+          /* (5) */
+          snd_mychip_save_registers(chip);
+          /* (6) */
+          snd_mychip_stop_hardware(chip);
+          /* (7) */
+          pci_disable_device(pci);
+          pci_save_state(pci);
+          return 0;
+  }
+
+
+The scheme of the real resume job is as follows.
+
+1. Retrieve the card and the chip data.
+
+2. Set up PCI. First, call :c:func:`pci_restore_state()`. Then
+   enable the pci device again by calling
+   :c:func:`pci_enable_device()`. Call
+   :c:func:`pci_set_master()` if necessary, too.
+
+3. Re-initialize the chip.
+
+4. Restore the saved registers if necessary.
+
+5. Resume the mixer, e.g. calling :c:func:`snd_ac97_resume()`.
+
+6. Restart the hardware (if any).
+
+7. Call :c:func:`snd_power_change_state()` with
+   ``SNDRV_CTL_POWER_D0`` to notify the processes.
+
+A typical code would be like:
+
+::
+
+  static int mychip_resume(struct pci_dev *pci)
+  {
+          /* (1) */
+          struct snd_card *card = pci_get_drvdata(pci);
+          struct mychip *chip = card->private_data;
+          /* (2) */
+          pci_restore_state(pci);
+          pci_enable_device(pci);
+          pci_set_master(pci);
+          /* (3) */
+          snd_mychip_reinit_chip(chip);
+          /* (4) */
+          snd_mychip_restore_registers(chip);
+          /* (5) */
+          snd_ac97_resume(chip->ac97);
+          /* (6) */
+          snd_mychip_restart_chip(chip);
+          /* (7) */
+          snd_power_change_state(card, SNDRV_CTL_POWER_D0);
+          return 0;
+  }
+
+As shown in the above, it's better to save registers after suspending
+the PCM operations via :c:func:`snd_pcm_suspend_all()` or
+:c:func:`snd_pcm_suspend()`. It means that the PCM streams are
+already stopped when the register snapshot is taken. But, remember that
+you don't have to restart the PCM stream in the resume callback. It'll
+be restarted via trigger call with ``SNDRV_PCM_TRIGGER_RESUME`` when
+necessary.
+
+OK, we have all callbacks now. Let's set them up. In the initialization
+of the card, make sure that you can get the chip data from the card
+instance, typically via ``private_data`` field, in case you created the
+chip data individually.
+
+::
+
+  static int snd_mychip_probe(struct pci_dev *pci,
+                              const struct pci_device_id *pci_id)
+  {
+          ....
+          struct snd_card *card;
+          struct mychip *chip;
+          int err;
+          ....
+          err = snd_card_new(&pci->dev, index[dev], id[dev], THIS_MODULE,
+                             0, &card);
+          ....
+          chip = kzalloc(sizeof(*chip), GFP_KERNEL);
+          ....
+          card->private_data = chip;
+          ....
+  }
+
+When you created the chip data with :c:func:`snd_card_new()`, it's
+anyway accessible via ``private_data`` field.
+
+::
+
+  static int snd_mychip_probe(struct pci_dev *pci,
+                              const struct pci_device_id *pci_id)
+  {
+          ....
+          struct snd_card *card;
+          struct mychip *chip;
+          int err;
+          ....
+          err = snd_card_new(&pci->dev, index[dev], id[dev], THIS_MODULE,
+                             sizeof(struct mychip), &card);
+          ....
+          chip = card->private_data;
+          ....
+  }
+
+If you need a space to save the registers, allocate the buffer for it
+here, too, since it would be fatal if you cannot allocate a memory in
+the suspend phase. The allocated buffer should be released in the
+corresponding destructor.
+
+And next, set suspend/resume callbacks to the pci_driver.
+
+::
+
+  static struct pci_driver driver = {
+          .name = KBUILD_MODNAME,
+          .id_table = snd_my_ids,
+          .probe = snd_my_probe,
+          .remove = snd_my_remove,
+  #ifdef CONFIG_PM
+          .suspend = snd_my_suspend,
+          .resume = snd_my_resume,
+  #endif
+  };
+
+Module Parameters
+=================
+
+There are standard module options for ALSA. At least, each module should
+have the ``index``, ``id`` and ``enable`` options.
+
+If the module supports multiple cards (usually up to 8 = ``SNDRV_CARDS``
+cards), they should be arrays. The default initial values are defined
+already as constants for easier programming:
+
+::
+
+  static int index[SNDRV_CARDS] = SNDRV_DEFAULT_IDX;
+  static char *id[SNDRV_CARDS] = SNDRV_DEFAULT_STR;
+  static int enable[SNDRV_CARDS] = SNDRV_DEFAULT_ENABLE_PNP;
+
+If the module supports only a single card, they could be single
+variables, instead. ``enable`` option is not always necessary in this
+case, but it would be better to have a dummy option for compatibility.
+
+The module parameters must be declared with the standard
+``module_param()()``, ``module_param_array()()`` and
+:c:func:`MODULE_PARM_DESC()` macros.
+
+The typical coding would be like below:
+
+::
+
+  #define CARD_NAME "My Chip"
+
+  module_param_array(index, int, NULL, 0444);
+  MODULE_PARM_DESC(index, "Index value for " CARD_NAME " soundcard.");
+  module_param_array(id, charp, NULL, 0444);
+  MODULE_PARM_DESC(id, "ID string for " CARD_NAME " soundcard.");
+  module_param_array(enable, bool, NULL, 0444);
+  MODULE_PARM_DESC(enable, "Enable " CARD_NAME " soundcard.");
+
+Also, don't forget to define the module description, classes, license
+and devices. Especially, the recent modprobe requires to define the
+module license as GPL, etc., otherwise the system is shown as “tainted”.
+
+::
+
+  MODULE_DESCRIPTION("My Chip");
+  MODULE_LICENSE("GPL");
+  MODULE_SUPPORTED_DEVICE("{{Vendor,My Chip Name}}");
+
+
+How To Put Your Driver Into ALSA Tree
+=====================================
+
+General
+-------
+
+So far, you've learned how to write the driver codes. And you might have
+a question now: how to put my own driver into the ALSA driver tree? Here
+(finally :) the standard procedure is described briefly.
+
+Suppose that you create a new PCI driver for the card “xyz”. The card
+module name would be snd-xyz. The new driver is usually put into the
+alsa-driver tree, ``alsa-driver/pci`` directory in the case of PCI
+cards. Then the driver is evaluated, audited and tested by developers
+and users. After a certain time, the driver will go to the alsa-kernel
+tree (to the corresponding directory, such as ``alsa-kernel/pci``) and
+eventually will be integrated into the Linux 2.6 tree (the directory
+would be ``linux/sound/pci``).
+
+In the following sections, the driver code is supposed to be put into
+alsa-driver tree. The two cases are covered: a driver consisting of a
+single source file and one consisting of several source files.
+
+Driver with A Single Source File
+--------------------------------
+
+1. Modify alsa-driver/pci/Makefile
+
+   Suppose you have a file xyz.c. Add the following two lines
+
+::
+
+  snd-xyz-objs := xyz.o
+  obj-$(CONFIG_SND_XYZ) += snd-xyz.o
+
+2. Create the Kconfig entry
+
+   Add the new entry of Kconfig for your xyz driver. config SND_XYZ
+   tristate "Foobar XYZ" depends on SND select SND_PCM help Say Y here
+   to include support for Foobar XYZ soundcard. To compile this driver
+   as a module, choose M here: the module will be called snd-xyz. the
+   line, select SND_PCM, specifies that the driver xyz supports PCM. In
+   addition to SND_PCM, the following components are supported for
+   select command: SND_RAWMIDI, SND_TIMER, SND_HWDEP,
+   SND_MPU401_UART, SND_OPL3_LIB, SND_OPL4_LIB, SND_VX_LIB,
+   SND_AC97_CODEC. Add the select command for each supported
+   component.
+
+   Note that some selections imply the lowlevel selections. For example,
+   PCM includes TIMER, MPU401_UART includes RAWMIDI, AC97_CODEC
+   includes PCM, and OPL3_LIB includes HWDEP. You don't need to give
+   the lowlevel selections again.
+
+   For the details of Kconfig script, refer to the kbuild documentation.
+
+3. Run cvscompile script to re-generate the configure script and build
+   the whole stuff again.
+
+Drivers with Several Source Files
+---------------------------------
+
+Suppose that the driver snd-xyz have several source files. They are
+located in the new subdirectory, pci/xyz.
+
+1. Add a new directory (``xyz``) in ``alsa-driver/pci/Makefile`` as
+   below
+
+::
+
+  obj-$(CONFIG_SND) += xyz/
+
+
+2. Under the directory ``xyz``, create a Makefile
+
+::
+
+         ifndef SND_TOPDIR
+         SND_TOPDIR=../..
+         endif
+
+         include $(SND_TOPDIR)/toplevel.config
+         include $(SND_TOPDIR)/Makefile.conf
+

+Useful Functions
+================
+
+:c:func:`snd_printk()` and friends
+---------------------------------------
+
+ALSA provides a verbose version of the :c:func:`printk()` function.
+If a kernel config ``CONFIG_SND_VERBOSE_PRINTK`` is set, this function
+prints the given message together with the file name and the line of the
+caller. The ``KERN_XXX`` prefix is processed as well as the original
+:c:func:`printk()` does, so it's recommended to add this prefix,
+e.g. snd_printk(KERN_ERR "Oh my, sorry, it's extremely bad!\\n");
+
+There are also :c:func:`printk()`'s for debugging.
+:c:func:`snd_printd()` can be used for general debugging purposes.
+If ``CONFIG_SND_DEBUG`` is set, this function is compiled, and works
+just like :c:func:`snd_printk()`. If the ALSA is compiled without
+the debugging flag, it's ignored.
+
+:c:func:`snd_printdd()` is compiled in only when
+``CONFIG_SND_DEBUG_VERBOSE`` is set. Please note that
+``CONFIG_SND_DEBUG_VERBOSE`` is not set as default even if you configure
+the alsa-driver with ``--with-debug=full`` option. You need to give
+explicitly ``--with-debug=detect`` option instead.
+
+:c:func:`snd_BUG()`
+------------------------
+
+It shows the ``BUG?`` message and stack trace as well as
+:c:func:`snd_BUG_ON()` at the point. It's useful to show that a
+fatal error happens there.
+
+When no debug flag is set, this macro is ignored.
+
+:c:func:`snd_BUG_ON()`
+----------------------------
+
+:c:func:`snd_BUG_ON()` macro is similar with
+:c:func:`WARN_ON()` macro. For example, snd_BUG_ON(!pointer); or
+it can be used as the condition, if (snd_BUG_ON(non_zero_is_bug))
+return -EINVAL;
+
+The macro takes an conditional expression to evaluate. When
+``CONFIG_SND_DEBUG``, is set, if the expression is non-zero, it shows
+the warning message such as ``BUG? (xxx)`` normally followed by stack
+trace. In both cases it returns the evaluated value.

+codec-2 will receive the audio data and the user wants to play that
+audio through codec-3 without involving the CPU.This
+aforementioned case is the ideal case when codec to codec
+connection should be used.
+
+Your dai_link should appear as below in your machine

+    .ignore_suspend = 1,
+    .params = &dsp_codec_params,
+ },
+
+Above code snippet is motivated from sound/soc/samsung/speyside.c.
+
+Note the "params" callback which lets the dapm know that this
+dai_link is a codec to codec connection.
+
+In dapm core a route is created between cpu_dai playback widget
+and codec_dai capture widget for playback path and vice-versa is
+true for capture path. In order for this aforementioned route to get
+triggered, DAPM needs to find a valid endpoint which could be either
+a sink or source widget corresponding to playback and capture path
+respectively.
+
+In order to trigger this dai_link widget, a thin codec driver for
+the speaker amp can be created as demonstrated in wm8727.c file, it
+sets appropriate constraints for the device even if it needs no control.
+
+Make sure to name your corresponding cpu and codec playback and capture
+dai names ending with "Playback" and "Capture" respectively as dapm core
+will link and power those dais based on the name.
+
+Note that in current device tree there is no way to mark a dai_link
+as codec to codec. However, it may change in future.

-2.3 Machine domain Widgets
---------------------------
+Machine domain Widgets
+----------------------
 
 Machine widgets are different from codec widgets in that they don't have a
 codec register bit associated with them. A machine widget is assigned to each
 machine audio component (non codec or DSP) that can be independently
 powered. e.g.
 
- o Speaker Amp
- o Microphone Bias
- o Jack connectors

+Codec (BIAS) Domain

 The codec bias power domain has no widgets and is handled by the codecs DAPM
 event handler. This handler is called when the codec powerstate is changed wrt
 to any stream event or by kernel PM events.
 
 
-2.5 Virtual Widgets

+Virtual Widgets

 Sometimes widgets exist in the codec or machine audio map that don't have any
 corresponding soft power control. In this case it is necessary to create
 a virtual widget - a widget with no control bits e.g.

+EXCEPTIONS_FILE with describes what elements will be either ignored or
+be pointed to a non-default reference.
+
+The output is written at the (OUT_FILE).
+
+It is capable of identifying defines, functions, structs, typedefs,
+enums and enum symbols and create cross-references for all of them.
+It is also capable of distinguish #define used for specifying a Linux
+ioctl.
+
+The EXCEPTIONS_FILE contain two rules to allow ignoring a symbol or
+to replace the default references by a custom one.

-Rules on how to access information in the Linux kernel sysfs
-
-The kernel-exported sysfs exports internal kernel implementation details
-and depends on internal kernel structures and layout. It is agreed upon
-by the kernel developers that the Linux kernel does not provide a stable
-internal API. Therefore, there are aspects of the sysfs interface that
-may not be stable across kernel releases.
-
-To minimize the risk of breaking users of sysfs, which are in most cases
-low-level userspace applications, with a new kernel release, the users
-of sysfs must follow some rules to use an as-abstract-as-possible way to
-access this filesystem. The current udev and HAL programs already
-implement this and users are encouraged to plug, if possible, into the
-abstractions these programs provide instead of accessing sysfs directly.
-
-But if you really do want or need to access sysfs directly, please follow
-the following rules and then your programs should work with future
-versions of the sysfs interface.
-
-- Do not use libsysfs
-  It makes assumptions about sysfs which are not true. Its API does not
-  offer any abstraction, it exposes all the kernel driver-core
-  implementation details in its own API. Therefore it is not better than
-  reading directories and opening the files yourself.
-  Also, it is not actively maintained, in the sense of reflecting the
-  current kernel development. The goal of providing a stable interface
-  to sysfs has failed; it causes more problems than it solves. It
-  violates many of the rules in this document.
-
-- sysfs is always at /sys
-  Parsing /proc/mounts is a waste of time. Other mount points are a
-  system configuration bug you should not try to solve. For test cases,
-  possibly support a SYSFS_PATH environment variable to overwrite the
-  application's behavior, but never try to search for sysfs. Never try
-  to mount it, if you are not an early boot script.
-
-- devices are only "devices"
-  There is no such thing like class-, bus-, physical devices,
-  interfaces, and such that you can rely on in userspace. Everything is
-  just simply a "device". Class-, bus-, physical, ... types are just
-  kernel implementation details which should not be expected by
-  applications that look for devices in sysfs.
-
-  The properties of a device are:
-    o devpath (/devices/pci0000:00/0000:00:1d.1/usb2/2-2/2-2:1.0)
-      - identical to the DEVPATH value in the event sent from the kernel
-        at device creation and removal
-      - the unique key to the device at that point in time
-      - the kernel's path to the device directory without the leading
-        /sys, and always starting with a slash
-      - all elements of a devpath must be real directories. Symlinks
-        pointing to /sys/devices must always be resolved to their real
-        target and the target path must be used to access the device.
-        That way the devpath to the device matches the devpath of the
-        kernel used at event time.
-      - using or exposing symlink values as elements in a devpath string
-        is a bug in the application
-
-    o kernel name (sda, tty, 0000:00:1f.2, ...)
-      - a directory name, identical to the last element of the devpath
-      - applications need to handle spaces and characters like '!' in
-        the name
-
-    o subsystem (block, tty, pci, ...)
-      - simple string, never a path or a link
-      - retrieved by reading the "subsystem"-link and using only the
-        last element of the target path
-
-    o driver (tg3, ata_piix, uhci_hcd)
-      - a simple string, which may contain spaces, never a path or a
-        link
-      - it is retrieved by reading the "driver"-link and using only the
-        last element of the target path
-      - devices which do not have "driver"-link just do not have a
-        driver; copying the driver value in a child device context is a
-        bug in the application
-
-    o attributes
-      - the files in the device directory or files below subdirectories
-        of the same device directory
-      - accessing attributes reached by a symlink pointing to another device,
-        like the "device"-link, is a bug in the application
-
-  Everything else is just a kernel driver-core implementation detail
-  that should not be assumed to be stable across kernel releases.
-
-- Properties of parent devices never belong into a child device.
-  Always look at the parent devices themselves for determining device
-  context properties. If the device 'eth0' or 'sda' does not have a
-  "driver"-link, then this device does not have a driver. Its value is empty.
-  Never copy any property of the parent-device into a child-device. Parent
-  device properties may change dynamically without any notice to the
-  child device.
-
-- Hierarchy in a single device tree
-  There is only one valid place in sysfs where hierarchy can be examined
-  and this is below: /sys/devices.
-  It is planned that all device directories will end up in the tree
-  below this directory.
-
-- Classification by subsystem
-  There are currently three places for classification of devices:
-  /sys/block, /sys/class and /sys/bus. It is planned that these will
-  not contain any device directories themselves, but only flat lists of
-  symlinks pointing to the unified /sys/devices tree.
-  All three places have completely different rules on how to access
-  device information. It is planned to merge all three
-  classification directories into one place at /sys/subsystem,
-  following the layout of the bus directories. All buses and
-  classes, including the converted block subsystem, will show up
-  there.
-  The devices belonging to a subsystem will create a symlink in the
-  "devices" directory at /sys/subsystem/<name>/devices.
-
-  If /sys/subsystem exists, /sys/bus, /sys/class and /sys/block can be
-  ignored. If it does not exist, you always have to scan all three
-  places, as the kernel is free to move a subsystem from one place to
-  the other, as long as the devices are still reachable by the same
-  subsystem name.
-
-  Assuming /sys/class/<subsystem> and /sys/bus/<subsystem>, or
-  /sys/block and /sys/class/block are not interchangeable is a bug in
-  the application.
-
-- Block
-  The converted block subsystem at /sys/class/block or
-  /sys/subsystem/block will contain the links for disks and partitions
-  at the same level, never in a hierarchy. Assuming the block subsystem to
-  contain only disks and not partition devices in the same flat list is
-  a bug in the application.
-
-- "device"-link and <subsystem>:<kernel name>-links
-  Never depend on the "device"-link. The "device"-link is a workaround
-  for the old layout, where class devices are not created in
-  /sys/devices/ like the bus devices. If the link-resolving of a
-  device directory does not end in /sys/devices/, you can use the
-  "device"-link to find the parent devices in /sys/devices/. That is the
-  single valid use of the "device"-link; it must never appear in any
-  path as an element. Assuming the existence of the "device"-link for
-  a device in /sys/devices/ is a bug in the application.
-  Accessing /sys/class/net/eth0/device is a bug in the application.
-
-  Never depend on the class-specific links back to the /sys/class
-  directory.  These links are also a workaround for the design mistake
-  that class devices are not created in /sys/devices. If a device
-  directory does not contain directories for child devices, these links
-  may be used to find the child devices in /sys/class. That is the single
-  valid use of these links; they must never appear in any path as an
-  element. Assuming the existence of these links for devices which are
-  real child device directories in the /sys/devices tree is a bug in
-  the application.
-
-  It is planned to remove all these links when all class device
-  directories live in /sys/devices.
-
-- Position of devices along device chain can change.
-  Never depend on a specific parent device position in the devpath,
-  or the chain of parent devices. The kernel is free to insert devices into
-  the chain. You must always request the parent device you are looking for
-  by its subsystem value. You need to walk up the chain until you find
-  the device that matches the expected subsystem. Depending on a specific
-  position of a parent device or exposing relative paths using "../" to
-  access the chain of parents is a bug in the application.
-
-- When reading and writing sysfs device attribute files, avoid dependency
-  on specific error codes wherever possible. This minimizes coupling to
-  the error handling implementation within the kernel.
-
-  In general, failures to read or write sysfs device attributes shall
-  propagate errors wherever possible. Common errors include, but are not
-  limited to:
-
-  -EIO: The read or store operation is not supported, typically returned by
-        the sysfs system itself if the read or store pointer is NULL.
-
-  -ENXIO: The read or store operation failed
-
-  Error codes will not be changed without good reason, and should a change
-  to error codes result in user-space breakage, it will be fixed, or the
-  the offending change will be reverted.
-
-  Userspace applications can, however, expect the format and contents of
-  the attribute files to remain consistent in the absence of a version
-  attribute change in the context of a given attribute.

-Linux Magic System Request Key Hacks
-Documentation for sysrq.c
-
-*  What is the magic SysRq key?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-It is a 'magical' key combo you can hit which the kernel will respond to
-regardless of whatever else it is doing, unless it is completely locked up.
-
-*  How do I enable the magic SysRq key?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-You need to say "yes" to 'Magic SysRq key (CONFIG_MAGIC_SYSRQ)' when
-configuring the kernel. When running a kernel with SysRq compiled in,
-/proc/sys/kernel/sysrq controls the functions allowed to be invoked via
-the SysRq key. The default value in this file is set by the
-CONFIG_MAGIC_SYSRQ_DEFAULT_ENABLE config symbol, which itself defaults
-to 1. Here is the list of possible values in /proc/sys/kernel/sysrq:
-   0 - disable sysrq completely
-   1 - enable all functions of sysrq
-  >1 - bitmask of allowed sysrq functions (see below for detailed function
-       description):
-          2 =   0x2 - enable control of console logging level
-          4 =   0x4 - enable control of keyboard (SAK, unraw)
-          8 =   0x8 - enable debugging dumps of processes etc.
-         16 =  0x10 - enable sync command
-         32 =  0x20 - enable remount read-only
-         64 =  0x40 - enable signalling of processes (term, kill, oom-kill)
-        128 =  0x80 - allow reboot/poweroff
-        256 = 0x100 - allow nicing of all RT tasks
-
-You can set the value in the file by the following command:
-    echo "number" >/proc/sys/kernel/sysrq
-
-The number may be written here either as decimal or as hexadecimal
-with the 0x prefix. CONFIG_MAGIC_SYSRQ_DEFAULT_ENABLE must always be
-written in hexadecimal.
-
-Note that the value of /proc/sys/kernel/sysrq influences only the invocation
-via a keyboard. Invocation of any operation via /proc/sysrq-trigger is always
-allowed (by a user with admin privileges).
-
-*  How do I use the magic SysRq key?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-On x86   - You press the key combo 'ALT-SysRq-<command key>'. Note - Some
-           keyboards may not have a key labeled 'SysRq'. The 'SysRq' key is
-           also known as the 'Print Screen' key. Also some keyboards cannot
-	   handle so many keys being pressed at the same time, so you might
-	   have better luck with "press Alt", "press SysRq", "release SysRq",
-	   "press <command key>", release everything.
-
-On SPARC - You press 'ALT-STOP-<command key>', I believe.
-
-On the serial console (PC style standard serial ports only) -
-           You send a BREAK, then within 5 seconds a command key. Sending
-           BREAK twice is interpreted as a normal BREAK.
-
-On PowerPC - Press 'ALT - Print Screen (or F13) - <command key>,  
-             Print Screen (or F13) - <command key> may suffice.
-
-On other - If you know of the key combos for other architectures, please
-           let me know so I can add them to this section.
-
-On all -  write a character to /proc/sysrq-trigger.  e.g.:
-
-		echo t > /proc/sysrq-trigger
-
-*  What are the 'command' keys?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-'b'     - Will immediately reboot the system without syncing or unmounting
-          your disks.
-
-'c'	- Will perform a system crash by a NULL pointer dereference.
-          A crashdump will be taken if configured.
-
-'d'	- Shows all locks that are held.
-
-'e'     - Send a SIGTERM to all processes, except for init.
-
-'f'	- Will call the oom killer to kill a memory hog process, but do not
-	  panic if nothing can be killed.
-
-'g'	- Used by kgdb (kernel debugger)
-
-'h'     - Will display help (actually any other key than those listed
-          here will display help. but 'h' is easy to remember :-)
-
-'i'     - Send a SIGKILL to all processes, except for init.
-
-'j'     - Forcibly "Just thaw it" - filesystems frozen by the FIFREEZE ioctl.
-
-'k'     - Secure Access Key (SAK) Kills all programs on the current virtual
-          console. NOTE: See important comments below in SAK section.
-
-'l'     - Shows a stack backtrace for all active CPUs.
-
-'m'     - Will dump current memory info to your console.
-
-'n'	- Used to make RT tasks nice-able
-
-'o'     - Will shut your system off (if configured and supported).
-
-'p'     - Will dump the current registers and flags to your console.
-
-'q'     - Will dump per CPU lists of all armed hrtimers (but NOT regular
-          timer_list timers) and detailed information about all
-          clockevent devices.
-
-'r'     - Turns off keyboard raw mode and sets it to XLATE.
-
-'s'     - Will attempt to sync all mounted filesystems.
-
-'t'     - Will dump a list of current tasks and their information to your
-          console.
-
-'u'     - Will attempt to remount all mounted filesystems read-only.
-
-'v'	- Forcefully restores framebuffer console
-'v'	- Causes ETM buffer dump [ARM-specific]
-
-'w'	- Dumps tasks that are in uninterruptable (blocked) state.
-
-'x'	- Used by xmon interface on ppc/powerpc platforms.
-          Show global PMU Registers on sparc64.
-          Dump all TLB entries on MIPS.
-
-'y'	- Show global CPU Registers [SPARC-64 specific]
-
-'z'	- Dump the ftrace buffer
-
-'0'-'9' - Sets the console log level, controlling which kernel messages
-          will be printed to your console. ('0', for example would make
-          it so that only emergency messages like PANICs or OOPSes would
-          make it to your console.)
-
-*  Okay, so what can I use them for?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Well, unraw(r) is very handy when your X server or a svgalib program crashes.
-
-sak(k) (Secure Access Key) is useful when you want to be sure there is no
-trojan program running at console which could grab your password
-when you would try to login. It will kill all programs on given console,
-thus letting you make sure that the login prompt you see is actually
-the one from init, not some trojan program.
-IMPORTANT: In its true form it is not a true SAK like the one in a :IMPORTANT
-IMPORTANT: c2 compliant system, and it should not be mistaken as   :IMPORTANT
-IMPORTANT: such.                                                   :IMPORTANT
-       It seems others find it useful as (System Attention Key) which is
-useful when you want to exit a program that will not let you switch consoles.
-(For example, X or a svgalib program.)
-
-reboot(b) is good when you're unable to shut down. But you should also
-sync(s) and umount(u) first.
-
-crash(c) can be used to manually trigger a crashdump when the system is hung.
-Note that this just triggers a crash if there is no dump mechanism available.
-
-sync(s) is great when your system is locked up, it allows you to sync your
-disks and will certainly lessen the chance of data loss and fscking. Note
-that the sync hasn't taken place until you see the "OK" and "Done" appear
-on the screen. (If the kernel is really in strife, you may not ever get the
-OK or Done message...)
-
-umount(u) is basically useful in the same ways as sync(s). I generally sync(s),
-umount(u), then reboot(b) when my system locks. It's saved me many a fsck.
-Again, the unmount (remount read-only) hasn't taken place until you see the
-"OK" and "Done" message appear on the screen.
-
-The loglevels '0'-'9' are useful when your console is being flooded with
-kernel messages you do not want to see. Selecting '0' will prevent all but
-the most urgent kernel messages from reaching your console. (They will
-still be logged if syslogd/klogd are alive, though.)
-
-term(e) and kill(i) are useful if you have some sort of runaway process you
-are unable to kill any other way, especially if it's spawning other
-processes.
-
-"just thaw it(j)" is useful if your system becomes unresponsive due to a frozen
-(probably root) filesystem via the FIFREEZE ioctl.
-
-*  Sometimes SysRq seems to get 'stuck' after using it, what can I do?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-That happens to me, also. I've found that tapping shift, alt, and control
-on both sides of the keyboard, and hitting an invalid sysrq sequence again
-will fix the problem. (i.e., something like alt-sysrq-z). Switching to another
-virtual console (ALT+Fn) and then back again should also help.
-
-*  I hit SysRq, but nothing seems to happen, what's wrong?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-There are some keyboards that produce a different keycode for SysRq than the
-pre-defined value of 99 (see KEY_SYSRQ in include/linux/input.h), or which
-don't have a SysRq key at all. In these cases, run 'showkey -s' to find an
-appropriate scancode sequence, and use 'setkeycodes <sequence> 99' to map
-this sequence to the usual SysRq code (e.g., 'setkeycodes e05b 99'). It's
-probably best to put this command in a boot script. Oh, and by the way, you
-exit 'showkey' by not typing anything for ten seconds.
-
-*  I want to add SysRQ key events to a module, how does it work?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-In order to register a basic function with the table, you must first include
-the header 'include/linux/sysrq.h', this will define everything else you need.
-Next, you must create a sysrq_key_op struct, and populate it with A) the key
-handler function you will use, B) a help_msg string, that will print when SysRQ
-prints help, and C) an action_msg string, that will print right before your
-handler is called. Your handler must conform to the prototype in 'sysrq.h'.
-
-After the sysrq_key_op is created, you can call the kernel function
-register_sysrq_key(int key, struct sysrq_key_op *op_p); this will
-register the operation pointed to by 'op_p' at table key 'key',
-if that slot in the table is blank. At module unload time, you must call
-the function unregister_sysrq_key(int key, struct sysrq_key_op *op_p), which
-will remove the key op pointed to by 'op_p' from the key 'key', if and only if
-it is currently registered in that slot. This is in case the slot has been
-overwritten since you registered it.
-
-The Magic SysRQ system works by registering key operations against a key op
-lookup table, which is defined in 'drivers/tty/sysrq.c'. This key table has
-a number of operations registered into it at compile time, but is mutable,
-and 2 functions are exported for interface to it:
-	register_sysrq_key and unregister_sysrq_key.
-Of course, never ever leave an invalid pointer in the table. I.e., when
-your module that called register_sysrq_key() exits, it must call
-unregister_sysrq_key() to clean up the sysrq key table entry that it used.
-Null pointers in the table are always safe. :)
-
-If for some reason you feel the need to call the handle_sysrq function from
-within a function called by handle_sysrq, you must be aware that you are in
-a lock (you are also in an interrupt handler, which means don't sleep!), so
-you must call __handle_sysrq_nolock instead.
-
-*  When I hit a SysRq key combination only the header appears on the console?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Sysrq output is subject to the same console loglevel control as all
-other console output.  This means that if the kernel was booted 'quiet'
-as is common on distro kernels the output may not appear on the actual
-console, even though it will appear in the dmesg buffer, and be accessible
-via the dmesg command and to the consumers of /proc/kmsg.  As a specific
-exception the header line from the sysrq command is passed to all console
-consumers as if the current loglevel was maximum.  If only the header
-is emitted it is almost certain that the kernel loglevel is too low.
-Should you require the output on the console channel then you will need
-to temporarily up the console loglevel using alt-sysrq-8 or:
-
-    echo 8 > /proc/sysrq-trigger
-
-Remember to return the loglevel to normal after triggering the sysrq
-command you are interested in.
-
-*  I have more questions, who can I ask?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Just ask them on the linux-kernel mailing list:
-	linux-kernel@vger.kernel.org

+Host Debugger Mode
+==================
+
+It is possible to configure the Trace Hub and control its trace
+capture from a remote debug host, which should be connected via one of
+the hardware debugging interfaces, which will then be used to both
+control Intel Trace Hub and transfer its trace data to the debug host.
+
+The driver needs to be told that such an arrangement is taking place
+so that it does not touch any capture/port configuration and avoids
+conflicting with the debug host's configuration accesses. The only
+activity that the driver will perform in this mode is collecting
+software traces to the Software Trace Hub (an stm class device). The
+user is still responsible for setting up adequate master/channel
+mappings that the decoder on the receiving end would recognize.
+
+In order to enable the host mode, set the 'host_mode' parameter of the
+'intel_th' kernel module to 'y'. None of the virtual output devices
+will show up on the intel_th bus. Also, trace configuration and
+capture controlling attribute groups of the 'gth' device will not be
+exposed. The 'sth' device will operate as usual.

+==========
+
 For kernel-based trace sources, there is "stm_source" device
 class. Devices of this class can be connected and disconnected to/from
-stm devices at runtime via a sysfs attribute.
+stm devices at runtime via a sysfs attribute called "stm_source_link"

-Examples of STM devices are Intel(R) Trace Hub [1] and Coresight STM
-[2].
+$ echo dummy_stm.0 > /sys/class/stm_source/console/stm_source_link
+
+For examples on how to use stm_source interface in the kernel, refer
+to stm_console or stm_heartbeat drivers.
+
+Each stm_source device will need to assume a master and a range of
+channels, depending on how many channels it requires. These are
+allocated for the device according to the policy configuration. If
+there's a node in the root of the policy directory that matches the
+stm_source device's name (for example, "console"), this node will be
+used to allocate master and channel numbers. If there's no such policy
+node, the stm core will pick the first contiguous chunk of channels
+within the first available master. Note that the node must exist
+before the stm_source device is connected to its stm device.
+
+stm_console
+===========
+
+One implementation of this interface also used in the example above is
+the "stm_console" driver, which basically provides a one-way console
+for kernel messages over an stm device.
+
+To configure the master/channel pair that will be assigned to this
+console in the STP stream, create a "console" policy entry (see the
+beginning of this text on how to do that). When initialized, it will
+consume one channel.

+Virtual Function I/O (VFIO) Mediated devices[1]
+===============================================
+
+The number of use cases for virtualizing DMA devices that do not have built-in
+SR_IOV capability is increasing. Previously, to virtualize such devices,
+developers had to create their own management interfaces and APIs, and then
+integrate them with user space software. To simplify integration with user space
+software, we have identified common requirements and a unified management
+interface for such devices.
+
+The VFIO driver framework provides unified APIs for direct device access. It is
+an IOMMU/device-agnostic framework for exposing direct device access to user
+space in a secure, IOMMU-protected environment. This framework is used for
+multiple devices, such as GPUs, network adapters, and compute accelerators. With
+direct device access, virtual machines or user space applications have direct
+access to the physical device. This framework is reused for mediated devices.
+
+The mediated core driver provides a common interface for mediated device
+management that can be used by drivers of different devices. This module
+provides a generic interface to perform these operations:
+
+* Create and destroy a mediated device
+* Add a mediated device to and remove it from a mediated bus driver
+* Add a mediated device to and remove it from an IOMMU group
+
+The mediated core driver also provides an interface to register a bus driver.
+For example, the mediated VFIO mdev driver is designed for mediated devices and
+supports VFIO APIs. The mediated bus driver adds a mediated device to and
+removes it from a VFIO group.
+
+The following high-level block diagram shows the main components and interfaces
+in the VFIO mediated driver framework. The diagram shows NVIDIA, Intel, and IBM
+devices as examples, as these devices are the first devices to use this module.

+
+Registration Interfaces
+=======================
+
+The mediated core driver provides the following types of registration
+interfaces:
+
+* Registration interface for a mediated bus driver
+* Physical device driver interface
+
+Registration Interface for a Mediated Bus Driver
+------------------------------------------------
+
+The registration interface for a mediated bus driver provides the following
+structure to represent a mediated device's driver:
+
+     /*
+      * struct mdev_driver [2] - Mediated device's driver
+      * @name: driver name
+      * @probe: called when new device created
+      * @remove: called when device removed
+      * @driver: device driver structure
+      */
+     struct mdev_driver {
+	     const char *name;
+	     int  (*probe)  (struct device *dev);
+	     void (*remove) (struct device *dev);
+	     struct device_driver    driver;
+     };
+
+A mediated bus driver for mdev should use this structure in the function calls
+to register and unregister itself with the core driver:
+
+* Register:
+
+  extern int  mdev_register_driver(struct mdev_driver *drv,
+				   struct module *owner);
+
+* Unregister:
+
+  extern void mdev_unregister_driver(struct mdev_driver *drv);
+
+The mediated bus driver is responsible for adding mediated devices to the VFIO
+group when devices are bound to the driver and removing mediated devices from
+the VFIO when devices are unbound from the driver.
+
+
+Physical Device Driver Interface
+--------------------------------
+
+The physical device driver interface provides the mdev_parent_ops[3] structure
+to define the APIs to manage work in the mediated core driver that is related
+to the physical device.
+
+The structures in the mdev_parent_ops structure are as follows:
+
+* dev_attr_groups: attributes of the parent device
+* mdev_attr_groups: attributes of the mediated device
+* supported_config: attributes to define supported configurations
+
+The functions in the mdev_parent_ops structure are as follows:
+
+* create: allocate basic resources in a driver for a mediated device
+* remove: free resources in a driver when a mediated device is destroyed
+
+The callbacks in the mdev_parent_ops structure are as follows:
+
+* open: open callback of mediated device
+* close: close callback of mediated device
+* ioctl: ioctl callback of mediated device
+* read : read emulation callback
+* write: write emulation callback
+* mmap: mmap emulation callback
+
+A driver should use the mdev_parent_ops structure in the function call to
+register itself with the mdev core driver:
+
+extern int  mdev_register_device(struct device *dev,
+                                 const struct mdev_parent_ops *ops);
+
+However, the mdev_parent_ops structure is not required in the function call
+that a driver should use to unregister itself with the mdev core driver:
+
+extern void mdev_unregister_device(struct device *dev);
+
+
+Mediated Device Management Interface Through sysfs
+==================================================
+
+The management interface through sysfs enables user space software, such as
+libvirt, to query and configure mediated devices in a hardware-agnostic fashion.
+This management interface provides flexibility to the underlying physical
+device's driver to support features such as:
+
+* Mediated device hot plug
+* Multiple mediated devices in a single virtual machine
+* Multiple mediated devices from different physical devices
+
+Links in the mdev_bus Class Directory
+-------------------------------------
+The /sys/class/mdev_bus/ directory contains links to devices that are registered
+with the mdev core driver.
+
+Directories and files under the sysfs for Each Physical Device
+--------------------------------------------------------------
+
+|- [parent physical device]
+|--- Vendor-specific-attributes [optional]
+|--- [mdev_supported_types]
+|     |--- [<type-id>]
+|     |   |--- create
+|     |   |--- name
+|     |   |--- available_instances
+|     |   |--- device_api

+|          |--- device_api
+|          |--- description
+|          |--- [devices]
+
+* [mdev_supported_types]
+
+  The list of currently supported mediated device types and their details.
+
+  [<type-id>], device_api, and available_instances are mandatory attributes
+  that should be provided by vendor driver.
+
+* [<type-id>]
+
+  The [<type-id>] name is created by adding the the device driver string as a
+  prefix to the string provided by the vendor driver. This format of this name
+  is as follows:
+
+	sprintf(buf, "%s-%s", dev_driver_string(parent->dev), group->name);
+
+  (or using mdev_parent_dev(mdev) to arrive at the parent device outside
+   of the core mdev code)
+
+* device_api
+
+  This attribute should show which device API is being created, for example,
+  "vfio-pci" for a PCI device.
+
+* available_instances
+
+  This attribute should show the number of devices of type <type-id> that can be
+  created.
+
+* [device]
+
+  This directory contains links to the devices of type <type-id> that have been
+created.
+
+* name
+
+  This attribute should show human readable name. This is optional attribute.
+
+* description
+
+  This attribute should show brief features/description of the type. This is
+  optional attribute.
+
+Directories and Files Under the sysfs for Each mdev Device
+----------------------------------------------------------
+
+|- [parent phy device]
+|--- [$MDEV_UUID]
+         |--- remove
+         |--- mdev_type {link to its type}
+         |--- vendor-specific-attributes [optional]
+
+* remove (write only)
+Writing '1' to the 'remove' file destroys the mdev device. The vendor driver can
+fail the remove() callback if that device is active and the vendor driver
+doesn't support hot unplug.
+
+Example:
+	# echo 1 > /sys/bus/mdev/devices/$mdev_UUID/remove
+
+Mediated device Hot plug:
+------------------------
+
+Mediated devices can be created and assigned at runtime. The procedure to hot
+plug a mediated device is the same as the procedure to hot plug a PCI device.
+
+Translation APIs for Mediated Devices
+=====================================
+
+The following APIs are provided for translating user pfn to host pfn in a VFIO
+driver:
+
+extern int vfio_pin_pages(struct device *dev, unsigned long *user_pfn,
+                          int npage, int prot, unsigned long *phys_pfn);
+
+extern int vfio_unpin_pages(struct device *dev, unsigned long *user_pfn,
+                            int npage);
+
+These functions call back into the back-end IOMMU module by using the pin_pages
+and unpin_pages callbacks of the struct vfio_iommu_driver_ops[4]. Currently
+these callbacks are supported in the TYPE1 IOMMU module. To enable them for
+other IOMMU backend modules, such as PPC64 sPAPR module, they need to provide
+these two callback functions.
+
+Using the Sample Code
+=====================
+
+mtty.c in samples/vfio-mdev/ directory is a sample driver program to
+demonstrate how to use the mediated device framework.
+
+The sample driver creates an mdev device that simulates a serial port over a PCI
+card.
+
+1. Build and load the mtty.ko module.
+
+   This step creates a dummy device, /sys/devices/virtual/mtty/mtty/
+
+   Files in this device directory in sysfs are similar to the following:
+
+   # tree /sys/devices/virtual/mtty/mtty/
+      /sys/devices/virtual/mtty/mtty/
+      |-- mdev_supported_types
+      |   |-- mtty-1
+      |   |   |-- available_instances
+      |   |   |-- create
+      |   |   |-- device_api
+      |   |   |-- devices
+      |   |   `-- name
+      |   `-- mtty-2
+      |       |-- available_instances
+      |       |-- create
+      |       |-- device_api
+      |       |-- devices
+      |       `-- name
+      |-- mtty_dev
+      |   `-- sample_mtty_dev
+      |-- power
+      |   |-- autosuspend_delay_ms
+      |   |-- control
+      |   |-- runtime_active_time
+      |   |-- runtime_status
+      |   `-- runtime_suspended_time
+      |-- subsystem -> ../../../../class/mtty
+      `-- uevent
+
+2. Create a mediated device by using the dummy device that you created in the
+   previous step.
+
+   # echo "83b8f4f2-509f-382f-3c1e-e6bfe0fa1001" >	\
+              /sys/devices/virtual/mtty/mtty/mdev_supported_types/mtty-2/create
+
+3. Add parameters to qemu-kvm.
+
+   -device vfio-pci,\
+    sysfsdev=/sys/bus/mdev/devices/83b8f4f2-509f-382f-3c1e-e6bfe0fa1001
+
+4. Boot the VM.
+
+   In the Linux guest VM, with no hardware on the host, the device appears
+   as  follows:
+

+
+   In the Linux guest VM, dmesg output for the device is as follows:
+
+   serial 0000:00:05.0: PCI INT A -> Link[LNKA] -> GSI 10 (level, high) -> IRQ
+10
+   0000:00:05.0: ttyS1 at I/O 0xc150 (irq = 10) is a 16550A
+   0000:00:05.0: ttyS2 at I/O 0xc158 (irq = 10) is a 16550A
+
+
+5. In the Linux guest VM, check the serial ports.
+
+   # setserial -g /dev/ttyS*
+   /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4

+   /dev/ttyS2, UART: 16550A, Port: 0xc158, IRQ: 10
+
+6. Using a minicom or any terminal enulation program, open port /dev/ttyS1 or
+   /dev/ttyS2 with hardware flow control disabled.
+
+7. Type data on the minicom terminal or send data to the terminal emulation
+   program and read the data.
+
+   Data is loop backed from hosts mtty driver.
+
+8. Destroy the mediated device that you created.

+The KVM halt polling system
+===========================
+
+The KVM halt polling system provides a feature within KVM whereby the latency
+of a guest can, under some circumstances, be reduced by polling in the host
+for some time period after the guest has elected to no longer run by cedeing.
+That is, when a guest vcpu has ceded, or in the case of powerpc when all of the
+vcpus of a single vcore have ceded, the host kernel polls for wakeup conditions
+before giving up the cpu to the scheduler in order to let something else run.
+
+Polling provides a latency advantage in cases where the guest can be run again
+very quickly by at least saving us a trip through the scheduler, normally on
+the order of a few micro-seconds, although performance benefits are workload
+dependant. In the event that no wakeup source arrives during the polling
+interval or some other task on the runqueue is runnable the scheduler is
+invoked. Thus halt polling is especially useful on workloads with very short
+wakeup periods where the time spent halt polling is minimised and the time
+savings of not invoking the scheduler are distinguishable.
+
+The generic halt polling code is implemented in:
+
+	virt/kvm/kvm_main.c: kvm_vcpu_block()
+
+The powerpc kvm-hv specific case is implemented in:
+
+	arch/powerpc/kvm/book3s_hv.c: kvmppc_vcore_blocked()
+
+Halt Polling Interval
+=====================
+
+The maximum time for which to poll before invoking the scheduler, referred to
+as the halt polling interval, is increased and decreased based on the perceived
+effectiveness of the polling in an attempt to limit pointless polling.
+This value is stored in either the vcpu struct:
+
+	kvm_vcpu->halt_poll_ns
+
+or in the case of powerpc kvm-hv, in the vcore struct:
+
+	kvmppc_vcore->halt_poll_ns
+
+Thus this is a per vcpu (or vcore) value.
+
+During polling if a wakeup source is received within the halt polling interval,
+the interval is left unchanged. In the event that a wakeup source isn't
+received during the polling interval (and thus schedule is invoked) there are
+two options, either the polling interval and total block time[0] were less than
+the global max polling interval (see module params below), or the total block
+time was greater than the global max polling interval.
+
+In the event that both the polling interval and total block time were less than
+the global max polling interval then the polling interval can be increased in
+the hope that next time during the longer polling interval the wake up source
+will be received while the host is polling and the latency benefits will be
+received. The polling interval is grown in the function grow_halt_poll_ns() and
+is multiplied by the module parameter halt_poll_ns_grow.
+
+In the event that the total block time was greater than the global max polling
+interval then the host will never poll for long enough (limited by the global
+max) to wakeup during the polling interval so it may as well be shrunk in order
+to avoid pointless polling. The polling interval is shrunk in the function
+shrink_halt_poll_ns() and is divided by the module parameter
+halt_poll_ns_shrink, or set to 0 iff halt_poll_ns_shrink == 0.
+
+It is worth noting that this adjustment process attempts to hone in on some
+steady state polling interval but will only really do a good job for wakeups
+which come at an approximately constant rate, otherwise there will be constant
+adjustment of the polling interval.
+
+[0] total block time: the time between when the halt polling function is
+		      invoked and a wakeup source received (irrespective of
+		      whether the scheduler is invoked within that function).
+
+Module Parameters
+=================
+
+The kvm module has 3 tuneable module parameters to adjust the global max
+polling interval as well as the rate at which the polling interval is grown and
+shrunk. These variables are defined in include/linux/kvm_host.h and as module
+parameters in virt/kvm/kvm_main.c, or arch/powerpc/kvm/book3s_hv.c in the
+powerpc kvm-hv case.
+
+Module Parameter    |	     Description	      |	     Default Value
+--------------------------------------------------------------------------------
+halt_poll_ns	    | The global max polling interval | KVM_HALT_POLL_NS_DEFAULT
+		    | which defines the ceiling value |
+		    | of the polling interval for     | (per arch value)
+		    | each vcpu. 		      |
+--------------------------------------------------------------------------------
+halt_poll_ns_grow   | The value by which the halt     |	2
+		    | polling interval is multiplied  |
+		    | in the grow_halt_poll_ns()      |
+		    | function.			      |
+--------------------------------------------------------------------------------
+halt_poll_ns_shrink | The value by which the halt     |	0
+		    | polling interval is divided in  |
+		    | the shrink_halt_poll_ns()	      |
+		    | function.			      |
+--------------------------------------------------------------------------------
+
+These module parameters can be set from the debugfs files in:
+
+	/sys/module/kvm/parameters/
+
+Note: that these module parameters are system wide values and are not able to
+      be tuned on a per vm basis.
+
+Further Notes
+=============
+
+- Care should be taken when setting the halt_poll_ns module parameter as a
+large value has the potential to drive the cpu usage to 100% on a machine which
+would be almost entirely idle otherwise. This is because even if a guest has
+wakeups during which very little work is done and which are quite far apart, if
+the period is shorter than the global max polling interval (halt_poll_ns) then
+the host will always poll for the entire block time and thus cpu utilisation
+will go to 100%.
+
+- Halt polling essentially presents a trade off between power usage and latency
+and the module parameters should be used to tune the affinity for this. Idle
+cpu time is essentially converted to host kernel time with the aim of decreasing
+latency when entering the guest.
+
+- Halt polling will only be conducted by the host when no other tasks are
+runnable on that cpu, otherwise the polling will cease immediately and
+schedule will be invoked to allow that other task to run. Thus this doesn't
+allow a guest to denial of service the cpu.

+User Interface for Resource Allocation in Intel Resource Director Technology
+
+Copyright (C) 2016 Intel Corporation
+
+Fenghua Yu <fenghua.yu@intel.com>
+Tony Luck <tony.luck@intel.com>
+
+This feature is enabled by the CONFIG_INTEL_RDT_A Kconfig and the
+X86 /proc/cpuinfo flag bits "rdt", "cat_l3" and "cdp_l3".
+
+To use the feature mount the file system:
+
+ # mount -t resctrl resctrl [-o cdp] /sys/fs/resctrl
+
+mount options are:
+
+"cdp": Enable code/data prioritization in L3 cache allocations.
+
+
+Info directory
+--------------
+
+The 'info' directory contains information about the enabled
+resources. Each resource has its own subdirectory. The subdirectory
+names reflect the resource names. Each subdirectory contains the
+following files:
+
+"num_closids":  The number of CLOSIDs which are valid for this
+	        resource. The kernel uses the smallest number of
+		CLOSIDs of all enabled resources as limit.
+
+"cbm_mask":     The bitmask which is valid for this resource. This
+		mask is equivalent to 100%.
+
+"min_cbm_bits": The minimum number of consecutive bits which must be
+		set when writing a mask.
+
+
+Resource groups
+---------------
+Resource groups are represented as directories in the resctrl file
+system. The default group is the root directory. Other groups may be
+created as desired by the system administrator using the "mkdir(1)"
+command, and removed using "rmdir(1)".
+
+There are three files associated with each group:
+
+"tasks": A list of tasks that belongs to this group. Tasks can be
+	added to a group by writing the task ID to the "tasks" file
+	(which will automatically remove them from the previous
+	group to which they belonged). New tasks created by fork(2)
+	and clone(2) are added to the same group as their parent.
+	If a pid is not in any sub partition, it is in root partition
+	(i.e. default partition).
+
+"cpus": A bitmask of logical CPUs assigned to this group. Writing
+	a new mask can add/remove CPUs from this group. Added CPUs
+	are removed from their previous group. Removed ones are
+	given to the default (root) group. You cannot remove CPUs
+	from the default group.
+
+"schemata": A list of all the resources available to this group.
+	Each resource has its own line and format - see below for
+	details.
+
+When a task is running the following rules define which resources
+are available to it:
+
+1) If the task is a member of a non-default group, then the schemata
+for that group is used.
+
+2) Else if the task belongs to the default group, but is running on a
+CPU that is assigned to some specific group, then the schemata for
+the CPU's group is used.
+
+3) Otherwise the schemata for the default group is used.
+
+
+Schemata files - general concepts
+---------------------------------
+Each line in the file describes one resource. The line starts with
+the name of the resource, followed by specific values to be applied
+in each of the instances of that resource on the system.
+
+Cache IDs
+---------
+On current generation systems there is one L3 cache per socket and L2
+caches are generally just shared by the hyperthreads on a core, but this
+isn't an architectural requirement. We could have multiple separate L3
+caches on a socket, multiple cores could share an L2 cache. So instead
+of using "socket" or "core" to define the set of logical cpus sharing
+a resource we use a "Cache ID". At a given cache level this will be a
+unique number across the whole system (but it isn't guaranteed to be a
+contiguous sequence, there may be gaps).  To find the ID for each logical
+CPU look in /sys/devices/system/cpu/cpu*/cache/index*/id
+
+Cache Bit Masks (CBM)
+---------------------
+For cache resources we describe the portion of the cache that is available
+for allocation using a bitmask. The maximum value of the mask is defined
+by each cpu model (and may be different for different cache levels). It
+is found using CPUID, but is also provided in the "info" directory of
+the resctrl file system in "info/{resource}/cbm_mask". X86 hardware
+requires that these masks have all the '1' bits in a contiguous block. So
+0x3, 0x6 and 0xC are legal 4-bit masks with two bits set, but 0x5, 0x9
+and 0xA are not.  On a system with a 20-bit mask each bit represents 5%
+of the capacity of the cache. You could partition the cache into four
+equal parts with masks: 0x1f, 0x3e0, 0x7c00, 0xf8000.
+
+
+L3 details (code and data prioritization disabled)
+--------------------------------------------------
+With CDP disabled the L3 schemata format is:
+
+	L3:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+
+L3 details (CDP enabled via mount option to resctrl)
+----------------------------------------------------
+When CDP is enabled L3 control is split into two separate resources
+so you can specify independent masks for code and data like this:
+
+	L3data:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+	L3code:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+
+L2 details
+----------
+L2 cache does not support code and data prioritization, so the
+schemata format is always:
+
+	L2:<cache_id0>=<cbm>;<cache_id1>=<cbm>;...
+
+Example 1
+---------
+On a two socket machine (one L3 cache per socket) with just four bits
+for cache bit masks
+
+# mount -t resctrl resctrl /sys/fs/resctrl
+# cd /sys/fs/resctrl
+# mkdir p0 p1
+# echo "L3:0=3;1=c" > /sys/fs/resctrl/p0/schemata
+# echo "L3:0=3;1=3" > /sys/fs/resctrl/p1/schemata
+
+The default resource group is unmodified, so we have access to all parts
+of all caches (its schemata file reads "L3:0=f;1=f").
+
+Tasks that are under the control of group "p0" may only allocate from the
+"lower" 50% on cache ID 0, and the "upper" 50% of cache ID 1.
+Tasks in group "p1" use the "lower" 50% of cache on both sockets.
+
+Example 2
+---------
+Again two sockets, but this time with a more realistic 20-bit mask.
+
+Two real time tasks pid=1234 running on processor 0 and pid=5678 running on
+processor 1 on socket 0 on a 2-socket and dual core machine. To avoid noisy
+neighbors, each of the two real-time tasks exclusively occupies one quarter
+of L3 cache on socket 0.
+
+# mount -t resctrl resctrl /sys/fs/resctrl
+# cd /sys/fs/resctrl
+
+First we reset the schemata for the default group so that the "upper"
+50% of the L3 cache on socket 0 cannot be used by ordinary tasks:
+
+# echo "L3:0=3ff;1=fffff" > schemata
+
+Next we make a resource group for our first real time task and give
+it access to the "top" 25% of the cache on socket 0.
+
+# mkdir p0
+# echo "L3:0=f8000;1=fffff" > p0/schemata
+
+Finally we move our first real time task into this resource group. We
+also use taskset(1) to ensure the task always runs on a dedicated CPU
+on socket 0. Most uses of resource groups will also constrain which
+processors tasks run on.
+
+# echo 1234 > p0/tasks
+# taskset -cp 1 1234
+
+Ditto for the second real time task (with the remaining 25% of cache):
+
+# mkdir p1
+# echo "L3:0=7c00;1=fffff" > p1/schemata
+# echo 5678 > p1/tasks
+# taskset -cp 2 5678
+
+Example 3
+---------
+
+A single socket system which has real-time tasks running on core 4-7 and
+non real-time workload assigned to core 0-3. The real-time tasks share text
+and data, so a per task association is not required and due to interaction
+with the kernel it's desired that the kernel on these cores shares L3 with
+the tasks.
+
+# mount -t resctrl resctrl /sys/fs/resctrl
+# cd /sys/fs/resctrl
+
+First we reset the schemata for the default group so that the "upper"
+50% of the L3 cache on socket 0 cannot be used by ordinary tasks:
+
+# echo "L3:0=3ff" > schemata
+
+Next we make a resource group for our real time cores and give
+it access to the "top" 50% of the cache on socket 0.
+
+# mkdir p0
+# echo "L3:0=ffc00;" > p0/schemata
+
+Finally we move core 4-7 over to the new group and make sure that the
+kernel and the tasks running there get 50% of the cache.
+
+# echo C0 > p0/cpus

-        Linux kernel release 4.x <http://kernel.org/>
+Linux kernel
+============
 
-These are the release notes for Linux version 4.  Read them carefully,
-as they tell you what this is all about, explain how to install the
-kernel, and what to do if something goes wrong.
+This file was moved to Documentation/admin-guide/README.rst
 
-WHAT IS LINUX?
+Please notice that there are several guides for kernel developers and users.
+These guides can be rendered in a number of formats, like HTML and PDF.
 
-  Linux is a clone of the operating system Unix, written from scratch by
-  Linus Torvalds with assistance from a loosely-knit team of hackers across
-  the Net. It aims towards POSIX and Single UNIX Specification compliance.
+In order to build the documentation, use ``make htmldocs`` or
+``make pdfdocs``.
 
-  It has all the features you would expect in a modern fully-fledged Unix,
-  including true multitasking, virtual memory, shared libraries, demand
-  loading, shared copy-on-write executables, proper memory management,
-  and multistack networking including IPv4 and IPv6.
-
-  It is distributed under the GNU General Public License - see the
-  accompanying COPYING file for more details.
-
-ON WHAT HARDWARE DOES IT RUN?
-
-  Although originally developed first for 32-bit x86-based PCs (386 or higher),
-  today Linux also runs on (at least) the Compaq Alpha AXP, Sun SPARC and
-  UltraSPARC, Motorola 68000, PowerPC, PowerPC64, ARM, Hitachi SuperH, Cell,
-  IBM S/390, MIPS, HP PA-RISC, Intel IA-64, DEC VAX, AMD x86-64, AXIS CRIS,
-  Xtensa, Tilera TILE, AVR32, ARC and Renesas M32R architectures.
-
-  Linux is easily portable to most general-purpose 32- or 64-bit architectures
-  as long as they have a paged memory management unit (PMMU) and a port of the
-  GNU C compiler (gcc) (part of The GNU Compiler Collection, GCC). Linux has
-  also been ported to a number of architectures without a PMMU, although
-  functionality is then obviously somewhat limited.
-  Linux has also been ported to itself. You can now run the kernel as a
-  userspace application - this is called UserMode Linux (UML).
-
-DOCUMENTATION:
-
- - There is a lot of documentation available both in electronic form on
-   the Internet and in books, both Linux-specific and pertaining to
-   general UNIX questions.  I'd recommend looking into the documentation
-   subdirectories on any Linux FTP site for the LDP (Linux Documentation
-   Project) books.  This README is not meant to be documentation on the
-   system: there are much better sources available.
-
- - There are various README files in the Documentation/ subdirectory:
-   these typically contain kernel-specific installation notes for some
-   drivers for example. See Documentation/00-INDEX for a list of what
-   is contained in each file.  Please read the Changes file, as it
-   contains information about the problems, which may result by upgrading
-   your kernel.
-
- - The Documentation/DocBook/ subdirectory contains several guides for
-   kernel developers and users.  These guides can be rendered in a
-   number of formats:  PostScript (.ps), PDF, HTML, & man-pages, among others.
-   After installation, "make psdocs", "make pdfdocs", "make htmldocs",
-   or "make mandocs" will render the documentation in the requested format.
-
-INSTALLING the kernel source:
-
- - If you install the full sources, put the kernel tarball in a
-   directory where you have permissions (e.g. your home directory) and
-   unpack it:
-
-     xz -cd linux-4.X.tar.xz | tar xvf -
-
-   Replace "X" with the version number of the latest kernel.
-
-   Do NOT use the /usr/src/linux area! This area has a (usually
-   incomplete) set of kernel headers that are used by the library header
-   files.  They should match the library, and not get messed up by
-   whatever the kernel-du-jour happens to be.
-
- - You can also upgrade between 4.x releases by patching.  Patches are
-   distributed in the xz format.  To install by patching, get all the
-   newer patch files, enter the top level directory of the kernel source
-   (linux-4.X) and execute:
-
-     xz -cd ../patch-4.x.xz | patch -p1
-
-   Replace "x" for all versions bigger than the version "X" of your current
-   source tree, _in_order_, and you should be ok.  You may want to remove
-   the backup files (some-file-name~ or some-file-name.orig), and make sure
-   that there are no failed patches (some-file-name# or some-file-name.rej).
-   If there are, either you or I have made a mistake.
-
-   Unlike patches for the 4.x kernels, patches for the 4.x.y kernels
-   (also known as the -stable kernels) are not incremental but instead apply
-   directly to the base 4.x kernel.  For example, if your base kernel is 4.0
-   and you want to apply the 4.0.3 patch, you must not first apply the 4.0.1
-   and 4.0.2 patches. Similarly, if you are running kernel version 4.0.2 and
-   want to jump to 4.0.3, you must first reverse the 4.0.2 patch (that is,
-   patch -R) _before_ applying the 4.0.3 patch. You can read more on this in
-   Documentation/applying-patches.txt
-
-   Alternatively, the script patch-kernel can be used to automate this
-   process.  It determines the current kernel version and applies any
-   patches found.
-
-     linux/scripts/patch-kernel linux
-
-   The first argument in the command above is the location of the
-   kernel source.  Patches are applied from the current directory, but
-   an alternative directory can be specified as the second argument.
-
- - Make sure you have no stale .o files and dependencies lying around:
-
-     cd linux
-     make mrproper
-
-   You should now have the sources correctly installed.
-
-SOFTWARE REQUIREMENTS
-
-   Compiling and running the 4.x kernels requires up-to-date
-   versions of various software packages.  Consult
-   Documentation/Changes for the minimum version numbers required
-   and how to get updates for these packages.  Beware that using
-   excessively old versions of these packages can cause indirect
-   errors that are very difficult to track down, so don't assume that
-   you can just update packages when obvious problems arise during
-   build or operation.
-
-BUILD directory for the kernel:
-
-   When compiling the kernel, all output files will per default be
-   stored together with the kernel source code.
-   Using the option "make O=output/dir" allows you to specify an alternate
-   place for the output files (including .config).
-   Example:
-
-     kernel source code: /usr/src/linux-4.X
-     build directory:    /home/name/build/kernel
-
-   To configure and build the kernel, use:
-
-     cd /usr/src/linux-4.X
-     make O=/home/name/build/kernel menuconfig
-     make O=/home/name/build/kernel
-     sudo make O=/home/name/build/kernel modules_install install
-
-   Please note: If the 'O=output/dir' option is used, then it must be
-   used for all invocations of make.
-
-CONFIGURING the kernel:
-
-   Do not skip this step even if you are only upgrading one minor
-   version.  New configuration options are added in each release, and
-   odd problems will turn up if the configuration files are not set up
-   as expected.  If you want to carry your existing configuration to a
-   new version with minimal work, use "make oldconfig", which will
-   only ask you for the answers to new questions.
-
- - Alternative configuration commands are:
-
-     "make config"      Plain text interface.
-
-     "make menuconfig"  Text based color menus, radiolists & dialogs.
-
-     "make nconfig"     Enhanced text based color menus.
-
-     "make xconfig"     Qt based configuration tool.
-
-     "make gconfig"     GTK+ based configuration tool.
-
-     "make oldconfig"   Default all questions based on the contents of
-                        your existing ./.config file and asking about
-                        new config symbols.
-
-     "make silentoldconfig"
-                        Like above, but avoids cluttering the screen
-                        with questions already answered.
-                        Additionally updates the dependencies.
-
-     "make olddefconfig"
-                        Like above, but sets new symbols to their default
-                        values without prompting.
-
-     "make defconfig"   Create a ./.config file by using the default
-                        symbol values from either arch/$ARCH/defconfig
-                        or arch/$ARCH/configs/${PLATFORM}_defconfig,
-                        depending on the architecture.
-
-     "make ${PLATFORM}_defconfig"
-                        Create a ./.config file by using the default
-                        symbol values from
-                        arch/$ARCH/configs/${PLATFORM}_defconfig.
-                        Use "make help" to get a list of all available
-                        platforms of your architecture.
-
-     "make allyesconfig"
-                        Create a ./.config file by setting symbol
-                        values to 'y' as much as possible.
-
-     "make allmodconfig"
-                        Create a ./.config file by setting symbol
-                        values to 'm' as much as possible.
-
-     "make allnoconfig" Create a ./.config file by setting symbol
-                        values to 'n' as much as possible.
-
-     "make randconfig"  Create a ./.config file by setting symbol
-                        values to random values.
-
-     "make localmodconfig" Create a config based on current config and
-                           loaded modules (lsmod). Disables any module
-                           option that is not needed for the loaded modules.
-
-                           To create a localmodconfig for another machine,
-                           store the lsmod of that machine into a file
-                           and pass it in as a LSMOD parameter.
-
-                   target$ lsmod > /tmp/mylsmod
-                   target$ scp /tmp/mylsmod host:/tmp
-
-                   host$ make LSMOD=/tmp/mylsmod localmodconfig
-
-                           The above also works when cross compiling.
-
-     "make localyesconfig" Similar to localmodconfig, except it will convert
-                           all module options to built in (=y) options.
-
-   You can find more information on using the Linux kernel config tools
-   in Documentation/kbuild/kconfig.txt.
-
- - NOTES on "make config":
-
-    - Having unnecessary drivers will make the kernel bigger, and can
-      under some circumstances lead to problems: probing for a
-      nonexistent controller card may confuse your other controllers
-
-    - A kernel with math-emulation compiled in will still use the
-      coprocessor if one is present: the math emulation will just
-      never get used in that case.  The kernel will be slightly larger,
-      but will work on different machines regardless of whether they
-      have a math coprocessor or not.
-
-    - The "kernel hacking" configuration details usually result in a
-      bigger or slower kernel (or both), and can even make the kernel
-      less stable by configuring some routines to actively try to
-      break bad code to find kernel problems (kmalloc()).  Thus you
-      should probably answer 'n' to the questions for "development",
-      "experimental", or "debugging" features.
-
-COMPILING the kernel:
-
- - Make sure you have at least gcc 3.2 available.
-   For more information, refer to Documentation/Changes.
-
-   Please note that you can still run a.out user programs with this kernel.
-
- - Do a "make" to create a compressed kernel image. It is also
-   possible to do "make install" if you have lilo installed to suit the
-   kernel makefiles, but you may want to check your particular lilo setup first.
-
-   To do the actual install, you have to be root, but none of the normal
-   build should require that. Don't take the name of root in vain.
-
- - If you configured any of the parts of the kernel as `modules', you
-   will also have to do "make modules_install".
-
- - Verbose kernel compile/build output:
-
-   Normally, the kernel build system runs in a fairly quiet mode (but not
-   totally silent).  However, sometimes you or other kernel developers need
-   to see compile, link, or other commands exactly as they are executed.
-   For this, use "verbose" build mode.  This is done by passing
-   "V=1" to the "make" command, e.g.
-
-     make V=1 all
-
-   To have the build system also tell the reason for the rebuild of each
-   target, use "V=2".  The default is "V=0".
-
- - Keep a backup kernel handy in case something goes wrong.  This is
-   especially true for the development releases, since each new release
-   contains new code which has not been debugged.  Make sure you keep a
-   backup of the modules corresponding to that kernel, as well.  If you
-   are installing a new kernel with the same version number as your
-   working kernel, make a backup of your modules directory before you
-   do a "make modules_install".
-
-   Alternatively, before compiling, use the kernel config option
-   "LOCALVERSION" to append a unique suffix to the regular kernel version.
-   LOCALVERSION can be set in the "General Setup" menu.
-
- - In order to boot your new kernel, you'll need to copy the kernel
-   image (e.g. .../linux/arch/x86/boot/bzImage after compilation)
-   to the place where your regular bootable kernel is found.
-
- - Booting a kernel directly from a floppy without the assistance of a
-   bootloader such as LILO, is no longer supported.
-
-   If you boot Linux from the hard drive, chances are you use LILO, which
-   uses the kernel image as specified in the file /etc/lilo.conf.  The
-   kernel image file is usually /vmlinuz, /boot/vmlinuz, /bzImage or
-   /boot/bzImage.  To use the new kernel, save a copy of the old image
-   and copy the new image over the old one.  Then, you MUST RERUN LILO
-   to update the loading map! If you don't, you won't be able to boot
-   the new kernel image.
-
-   Reinstalling LILO is usually a matter of running /sbin/lilo.
-   You may wish to edit /etc/lilo.conf to specify an entry for your
-   old kernel image (say, /vmlinux.old) in case the new one does not
-   work.  See the LILO docs for more information.
-
-   After reinstalling LILO, you should be all set.  Shutdown the system,
-   reboot, and enjoy!
-
-   If you ever need to change the default root device, video mode,
-   ramdisk size, etc.  in the kernel image, use the 'rdev' program (or
-   alternatively the LILO boot options when appropriate).  No need to
-   recompile the kernel to change these parameters.
-
- - Reboot with the new kernel and enjoy.
-
-IF SOMETHING GOES WRONG:
-
- - If you have problems that seem to be due to kernel bugs, please check
-   the file MAINTAINERS to see if there is a particular person associated
-   with the part of the kernel that you are having trouble with. If there
-   isn't anyone listed there, then the second best thing is to mail
-   them to me (torvalds@linux-foundation.org), and possibly to any other
-   relevant mailing-list or to the newsgroup.
-
- - In all bug-reports, *please* tell what kernel you are talking about,
-   how to duplicate the problem, and what your setup is (use your common
-   sense).  If the problem is new, tell me so, and if the problem is
-   old, please try to tell me when you first noticed it.
-
- - If the bug results in a message like
-
-     unable to handle kernel paging request at address C0000010
-     Oops: 0002
-     EIP:   0010:XXXXXXXX
-     eax: xxxxxxxx   ebx: xxxxxxxx   ecx: xxxxxxxx   edx: xxxxxxxx
-     esi: xxxxxxxx   edi: xxxxxxxx   ebp: xxxxxxxx
-     ds: xxxx  es: xxxx  fs: xxxx  gs: xxxx
-     Pid: xx, process nr: xx
-     xx xx xx xx xx xx xx xx xx xx
-
-   or similar kernel debugging information on your screen or in your
-   system log, please duplicate it *exactly*.  The dump may look
-   incomprehensible to you, but it does contain information that may
-   help debugging the problem.  The text above the dump is also
-   important: it tells something about why the kernel dumped code (in
-   the above example, it's due to a bad kernel pointer). More information
-   on making sense of the dump is in Documentation/oops-tracing.txt
-
- - If you compiled the kernel with CONFIG_KALLSYMS you can send the dump
-   as is, otherwise you will have to use the "ksymoops" program to make
-   sense of the dump (but compiling with CONFIG_KALLSYMS is usually preferred).
-   This utility can be downloaded from
-   ftp://ftp.<country>.kernel.org/pub/linux/utils/kernel/ksymoops/ .
-   Alternatively, you can do the dump lookup by hand:
-
- - In debugging dumps like the above, it helps enormously if you can
-   look up what the EIP value means.  The hex value as such doesn't help
-   me or anybody else very much: it will depend on your particular
-   kernel setup.  What you should do is take the hex value from the EIP
-   line (ignore the "0010:"), and look it up in the kernel namelist to
-   see which kernel function contains the offending address.
-
-   To find out the kernel function name, you'll need to find the system
-   binary associated with the kernel that exhibited the symptom.  This is
-   the file 'linux/vmlinux'.  To extract the namelist and match it against
-   the EIP from the kernel crash, do:
-
-     nm vmlinux | sort | less
-
-   This will give you a list of kernel addresses sorted in ascending
-   order, from which it is simple to find the function that contains the
-   offending address.  Note that the address given by the kernel
-   debugging messages will not necessarily match exactly with the
-   function addresses (in fact, that is very unlikely), so you can't
-   just 'grep' the list: the list will, however, give you the starting
-   point of each kernel function, so by looking for the function that
-   has a starting address lower than the one you are searching for but
-   is followed by a function with a higher address you will find the one
-   you want.  In fact, it may be a good idea to include a bit of
-   "context" in your problem report, giving a few lines around the
-   interesting one.
-
-   If you for some reason cannot do the above (you have a pre-compiled
-   kernel image or similar), telling me as much about your setup as
-   possible will help.  Please read the REPORTING-BUGS document for details.
-
- - Alternatively, you can use gdb on a running kernel. (read-only; i.e. you
-   cannot change values or set break points.) To do this, first compile the
-   kernel with -g; edit arch/x86/Makefile appropriately, then do a "make
-   clean". You'll also need to enable CONFIG_PROC_FS (via "make config").
-
-   After you've rebooted with the new kernel, do "gdb vmlinux /proc/kcore".
-   You can now use all the usual gdb commands. The command to look up the
-   point where your system crashed is "l *0xXXXXXXXX". (Replace the XXXes
-   with the EIP value.)
-
-   gdb'ing a non-running kernel currently fails because gdb (wrongly)
-   disregards the starting offset for which the kernel is compiled.
+There are various text files in the Documentation/ subdirectory,
+several of them using the Restructured Text markup notation.
+See Documentation/00-INDEX for a list of what is contained in each file.
 
+Please read the Documentation/process/changes.rst file, as it contains the
+requirements for building and running the kernel, and information about
+the problems which may result by upgrading your kernel.

+	  This check also includes UXN, which should be set on all kernel
+	  mappings.
+
+	  Look for a message in dmesg output like this:

+
+	  Note that even if the check fails, your kernel is possibly
+	  still fine, as W+X mappings are not a security hole in
+	  themselves, what they do is that they make the exploitation
+	  of other unfixed kernel bugs easier.
+

+// SHA256/512 for ARMv8.
+//
+// Performance in cycles per processed byte and improvement coefficient
+// over code generated with "default" compiler:
+//
+//		SHA256-hw	SHA256(*)	SHA512
+// Apple A7	1.97		10.5 (+33%)	6.73 (-1%(**))
+// Cortex-A53	2.38		15.5 (+115%)	10.0 (+150%(***))
+// Cortex-A57	2.31		11.6 (+86%)	7.51 (+260%(***))
+// Denver	2.01		10.5 (+26%)	6.70 (+8%)
+// X-Gene			20.0 (+100%)	12.8 (+300%(***))
+// Mongoose	2.36		13.0 (+50%)	8.36 (+33%)
+//
+// (*)	Software SHA256 results are of lesser relevance, presented
+//	mostly for informational purposes.
+// (**)	The result is a trade-off: it's possible to improve it by
+//	10% (or by 1 cycle per round), but at the cost of 20% loss
+//	on Cortex-A53 (or by 4 cycles per round).
+// (***)	Super-impressive coefficients over gcc-generated code are
+//	indication of some compiler "pathology", most notably code
+//	generated with -mgeneral-regs-only is significanty faster
+//	and the gap is only 40-90%.
+//
+// October 2016.
+//
+// Originally it was reckoned that it makes no sense to implement NEON
+// version of SHA256 for 64-bit processors. This is because performance
+// improvement on most wide-spread Cortex-A5x processors was observed
+// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+// observed that 32-bit NEON SHA256 performs significantly better than
+// 64-bit scalar version on *some* of the more recent processors. As
+// result 64-bit NEON version of SHA256 was added to provide best
+// all-round performance. For example it executes ~30% faster on X-Gene
+// and Mongoose. [For reference, NEON version of SHA512 is bound to
+// deliver much less improvement, likely *negative* on Cortex-A5x.
+// Which is why NEON support is limited to SHA256.]

+#
+# Performance in cycles per processed byte and improvement coefficient
+# over code generated with "default" compiler:
+#
+#		SHA256-hw	SHA256(*)	SHA512
+# Apple A7	1.97		10.5 (+33%)	6.73 (-1%(**))
+# Cortex-A53	2.38		15.5 (+115%)	10.0 (+150%(***))
+# Cortex-A57	2.31		11.6 (+86%)	7.51 (+260%(***))
+# Denver	2.01		10.5 (+26%)	6.70 (+8%)
+# X-Gene			20.0 (+100%)	12.8 (+300%(***))
+# Mongoose	2.36		13.0 (+50%)	8.36 (+33%)
+#
+# (*)	Software SHA256 results are of lesser relevance, presented
+#	mostly for informational purposes.
+# (**)	The result is a trade-off: it's possible to improve it by
+#	10% (or by 1 cycle per round), but at the cost of 20% loss
+#	on Cortex-A53 (or by 4 cycles per round).
+# (***)	Super-impressive coefficients over gcc-generated code are
+#	indication of some compiler "pathology", most notably code
+#	generated with -mgeneral-regs-only is significanty faster
+#	and the gap is only 40-90%.
+#
+# October 2016.
+#
+# Originally it was reckoned that it makes no sense to implement NEON
+# version of SHA256 for 64-bit processors. This is because performance
+# improvement on most wide-spread Cortex-A5x processors was observed
+# to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+# observed that 32-bit NEON SHA256 performs significantly better than
+# 64-bit scalar version on *some* of the more recent processors. As
+# result 64-bit NEON version of SHA256 was added to provide best
+# all-round performance. For example it executes ~30% faster on X-Gene
+# and Mongoose. [For reference, NEON version of SHA512 is bound to
+# deliver much less improvement, likely *negative* on Cortex-A5x.
+# Which is why NEON support is limited to SHA256.]

+// SHA256/512 for ARMv8.
+//
+// Performance in cycles per processed byte and improvement coefficient
+// over code generated with "default" compiler:
+//
+//		SHA256-hw	SHA256(*)	SHA512
+// Apple A7	1.97		10.5 (+33%)	6.73 (-1%(**))
+// Cortex-A53	2.38		15.5 (+115%)	10.0 (+150%(***))
+// Cortex-A57	2.31		11.6 (+86%)	7.51 (+260%(***))
+// Denver	2.01		10.5 (+26%)	6.70 (+8%)
+// X-Gene			20.0 (+100%)	12.8 (+300%(***))
+// Mongoose	2.36		13.0 (+50%)	8.36 (+33%)
+//
+// (*)	Software SHA256 results are of lesser relevance, presented
+//	mostly for informational purposes.
+// (**)	The result is a trade-off: it's possible to improve it by
+//	10% (or by 1 cycle per round), but at the cost of 20% loss
+//	on Cortex-A53 (or by 4 cycles per round).
+// (***)	Super-impressive coefficients over gcc-generated code are
+//	indication of some compiler "pathology", most notably code
+//	generated with -mgeneral-regs-only is significanty faster
+//	and the gap is only 40-90%.
+//
+// October 2016.
+//
+// Originally it was reckoned that it makes no sense to implement NEON
+// version of SHA256 for 64-bit processors. This is because performance
+// improvement on most wide-spread Cortex-A5x processors was observed
+// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
+// observed that 32-bit NEON SHA256 performs significantly better than
+// 64-bit scalar version on *some* of the more recent processors. As
+// result 64-bit NEON version of SHA256 was added to provide best
+// all-round performance. For example it executes ~30% faster on X-Gene
+// and Mongoose. [For reference, NEON version of SHA512 is bound to
+// deliver much less improvement, likely *negative* on Cortex-A5x.
+// Which is why NEON support is limited to SHA256.]

+ * Copyright IBM Corp. 2016
+ * Author(s): Harald Freudenberger <freude@de.ibm.com>
+ *
+ * Currently there are two tracepoint events defined here.
+ * An s390_zcrypt_req request event occurs as soon as the request is
+ * recognized by the zcrypt ioctl function. This event may act as some kind
+ * of request-processing-starts-now indication.
+ * As late as possible within the zcrypt ioctl function there occurs the
+ * s390_zcrypt_rep event which may act as the point in time where the
+ * request has been processed by the kernel and the result is about to be
+ * transferred back to userspace.
+ * The glue which binds together request and reply event is the ptr
+ * parameter, which is the local buffer address where the request from
+ * userspace has been stored by the ioctl function.
+ *
+ * The main purpose of this zcrypt tracepoint api is to get some data for
+ * performance measurements together with information about on which card
+ * and queue the request has been processed. It is not an ffdc interface as
+ * there is already code in the zcrypt device driver to serve the s390
+ * debug feature interface.

- * 'lazy' is the traditional strategy, which is based on setting
- * CR0::TS to 1 during context-switch (instead of doing a full
- * restore of the FPU state), which causes the first FPU instruction
- * after the context switch (whenever it is executed) to fault - at
- * which point we lazily restore the FPU state into FPU registers.
- *
- * Tasks are of course under no obligation to execute FPU instructions,
- * so it can easily happen that another context-switch occurs without
- * a single FPU instruction being executed. If we eventually switch
- * back to the original task (that still owns the FPU) then we have
- * not only saved the restores along the way, but we also have the
- * FPU ready to be used for the original task.
- *
- * 'lazy' is deprecated because it's almost never a performance win
- * and it's much more complicated than 'eager'.
- *
- * 'eager' switching is by default on all CPUs, there we switch the FPU
- * state during every context switch, regardless of whether the task
- * has used FPU instructions in that time slice or not. This is done
- * because modern FPU context saving instructions are able to optimize
- * state saving and restoration in hardware: they can detect both
- * unused and untouched FPU state and optimize accordingly.
- *
- * [ Note that even in 'lazy' mode we might optimize context switches
- *   to use 'eager' restores, if we detect that a task is using the FPU
- *   frequently. See the fpu->counter logic in fpu/internal.h for that. ]

+ * - Monitor latencies in a defined window of time.
+ * - If the minimum latency in the above window exceeds some target, increment
+ *   scaling step and scale down queue depth by a factor of 2x. The monitoring
+ *   window is then shrunk to 100 / sqrt(scaling step + 1).
+ * - For any window where we don't have solid data on what the latencies
+ *   look like, retain status quo.
+ * - If latencies look good, decrement scaling step.
+ * - If we're only doing writes, allow the scaling step to go negative. This
+ *   will temporarily boost write performance, snapping back to a stable
+ *   scaling step of 0 if reads show up or the heavy writers finish. Unlike
+ *   positive scaling steps where we shrink the monitoring window, a negative
+ *   scaling step retains the default step==0 window size.
