+The Speakup User's Guide
+For Speakup 3.1.2 and Later
+By Gene Collins
+Updated by others
+Last modified on Mon Sep 27 14:26:31 2010
+Document version 1.3
+

+Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A
+copy of the license is included in the section entitled "GNU Free
+Documentation License".
+
+Preface
+
+The purpose of this document is to familiarize users with the user
+interface to Speakup, a Linux Screen Reader. If you need instructions
+for installing or obtaining Speakup, visit the web site at
+http://linux-speakup.org/. Speakup is a set of patches to the standard
+Linux kernel source tree. It can be built as a series of modules, or as
+a part of a monolithic kernel. These details are beyond the scope of
+this manual, but the user may need to be aware of the module
+capabilities, depending on how your system administrator has installed
+Speakup. If Speakup is built as a part of a monolithic kernel, and the
+user is using a hardware synthesizer, then Speakup will be able to
+provide speech access from the time the kernel is loaded, until the time
+the system is shutdown. This means that if you have obtained Linux
+installation media for a distribution which includes Speakup as a part
+of its kernel, you will be able, as a blind person, to install Linux
+with speech access unaided by a sighted person. Again, these details
+are beyond the scope of this manual, but the user should be aware of
+them. See the web site mentioned above for further details.
+
+1. Starting Speakup
+
+If your system administrator has installed Speakup to work with your
+specific synthesizer by default, then all you need to do to use Speakup
+is to boot your system, and Speakup should come up talking. This
+assumes of course that your synthesizer is a supported hardware
+synthesizer, and that it is either installed in or connected to your
+system, and is if necessary powered on.
+
+It is possible, however, that Speakup may have been compiled into the
+kernel with no default synthesizer. It is even possible that your
+kernel has been compiled with support for some of the supported
+synthesizers and not others. If you find that this is the case, and
+your synthesizer is supported but not available, complain to the person
+who compiled and installed your kernel. Or better yet, go to the web
+site, and learn how to patch Speakup into your own kernel source, and
+build and install your own kernel.
+
+If your kernel has been compiled with Speakup, and has no default
+synthesizer set, or you would like to use a different synthesizer than
+the default one, then you may issue the following command at the boot
+prompt of your boot loader.
+
+linux speakup.synth=ltlk
+
+This command would tell Speakup to look for and use a LiteTalk or
+DoubleTalk LT at boot up. You may replace the ltlk synthesizer keyword
+with the keyword for whatever synthesizer you wish to use. The
+speakup.synth parameter will accept the following keywords, provided
+that support for the related synthesizers has been built into the
+kernel.
+
+acntsa -- Accent SA
+acntpc -- Accent PC
+apollo -- Apollo
+audptr -- Audapter
+bns -- Braille 'n Speak
+dectlk -- DecTalk Express (old and new, db9 serial only)
+decext -- DecTalk (old) External
+dtlk -- DoubleTalk PC
+keypc -- Keynote Gold PC
+ltlk -- DoubleTalk LT, LiteTalk, or external Tripletalk (db9 serial only)
+spkout -- Speak Out
+txprt -- Transport
+dummy -- Plain text terminal
+
+Note: Speakup does * NOT * support usb connections! Speakup also does *
+NOT * support the internal Tripletalk!
+
+Speakup does support two other synthesizers, but because they work in
+conjunction with other software, they must be loaded as modules after
+their related software is loaded, and so are not available at boot up.
+These are as follows:
+
+decpc -- DecTalk PC (not available at boot up)
+soft -- One of several software synthesizers (not available at boot up)
+
+See the sections on loading modules and software synthesizers later in
+this manual for further details. It should be noted here that the
+speakup.synth boot parameter will have no effect if Speakup has been
+compiled as modules. In order for Speakup modules to be loaded during
+the boot process, such action must be configured by your system
+administrator. This will mean that you will hear some, but not all, of
+the bootup messages.
+
+2. Basic operation
+
+Once you have booted the system, and if necessary, have supplied the
+proper bootup parameter for your synthesizer, Speakup will begin
+talking as soon as the kernel is loaded. In fact, it will talk a lot!
+It will speak all the boot up messages that the kernel prints on the
+screen during the boot process. This is because Speakup is not a
+separate screen reader, but is actually built into the operating
+system. Since almost all console applications must print text on the
+screen using the kernel, and must get their keyboard input through the
+kernel, they are automatically handled properly by Speakup. There are a
+few exceptions, but we'll come to those later.
+
+Note: In this guide I will refer to the numeric keypad as the keypad.
+This is done because the speakupmap.map file referred to later in this
+manual uses the term keypad instead of numeric keypad. Also I'm lazy
+and would rather only type one word. So keypad it is. Got it? Good.
+
+Most of the Speakup review keys are located on the keypad at the far
+right of the keyboard. The numlock key should be off, in order for these
+to work. If you toggle the numlock on, the keypad will produce numbers,
+which is exactly what you want for spreadsheets and such. For the
+purposes of this guide, you should have the numlock turned off, which is
+its default state at bootup.
+
+You probably won't want to listen to all the bootup messages every time
+you start your system, though it's a good idea to listen to them at
+least once, just so you'll know what kind of information is available to
+you during the boot process. You can always review these messages after
+bootup with the command:
+
+dmesg | more
+
+In order to speed the boot process, and to silence the speaking of the
+bootup messages, just press the keypad enter key. This key is located
+in the bottom right corner of the keypad. Speakup will shut up and stay
+that way, until you press another key.
+
+You can check to see if the boot process has completed by pressing the 8
+key on the keypad, which reads the current line. This also has the
+effect of starting Speakup talking again, so you can press keypad enter
+to silence it again if the boot process has not completed.
+
+When the boot process is complete, you will arrive at a "login" prompt.
+At this point, you'll need to type in your user id and password, as
+provided by your system administrator. You will hear Speakup speak the
+letters of your user id as you type it, but not the password. This is
+because the password is not displayed on the screen for security
+reasons. This has nothing to do with Speakup, it's a Linux security
+feature.
+
+Once you've logged in, you can run any Linux command or program which is
+allowed by your user id. Normal users will not be able to run programs
+which require root privileges.
+
+When you are running a program or command, Speakup will automatically
+speak new text as it arrives on the screen. You can at any time silence
+the speech with keypad enter, or use any of the Speakup review keys.
+
+Here are some basic Speakup review keys, and a short description of what
+they do.
+
+keypad 1 -- read previous character
+keypad 2 -- read current character (pressing keypad 2 twice rapidly will speak
+ the current character phonetically)
+keypad 3 -- read next character
+keypad 4 -- read previous word
+keypad 5 -- read current word (press twice rapidly to spell the current word)
+keypad 6 -- read next word
+keypad 7 -- read previous line
+keypad 8 -- read current line (press twice rapidly to hear how much the
+ text on the current line is indented)
+keypad 9 -- read next line
+keypad period -- speak current cursor position and announce current
+ virtual console
+
+It's also worth noting that the insert key on the keypad is mapped
+as the speakup key. Instead of pressing and releasing this key, as you
+do under DOS or Windows, you hold it like a shift key, and press other
+keys in combination with it. For example, repeatedly holding keypad
+insert, from now on called speakup, and keypad enter will toggle the
+speaking of new text on the screen on and off. This is not the same as
+just pressing keypad enter by itself, which just silences the speech
+until you hit another key. When you hit speakup plus keypad enter,
+Speakup will say, "You turned me off.", or "Hey, that's better." When
+Speakup is turned off, no new text on the screen will be spoken. You
+can still use the reading controls to review the screen however.
+
+3. Using the Speakup Help System
+
+In order to enter the Speakup help system, press and hold the speakup
+key (remember that this is the keypad insert key), and press the f1 key.
+You will hear the message:
+
+"Press space to leave help, cursor up or down to scroll, or a letter to
+go to commands in list."
+
+When you press the spacebar to leave the help system, you will hear:
+
+"Leaving help."
+
+While you are in the Speakup help system, you can scroll up or down
+through the list of available commands using the cursor keys. The list
+of commands is arranged in alphabetical order. If you wish to jump to
+commands in a specific part of the alphabet, you may press the letter of
+the alphabet you wish to jump to.
+
+You can also just explore by typing keyboard keys. Pressing keys will
+cause Speakup to speak the command associated with that key. For
+example, if you press the keypad 8 key, you will hear:
+
+"Keypad 8 is line, say current."
+
+You'll notice that some commands do not have keys assigned to them.
+This is because they are very infrequently used commands, and are also
+accessible through the sys system. We'll discuss the sys system later
+in this manual.
+
+You'll also notice that some commands have two keys assigned to them.
+This is because Speakup has a built in set of alternative key bindings
+for laptop users. The alternate speakup key is the caps lock key. You
+can press and hold the caps lock key, while pressing an alternate
+speakup command key to activate the command. On most laptops, the
+numeric keypad is defined as the keys in the j k l area of the keyboard.
+
+There is usually a function key which turns this keypad function on and
+off, and some other key which controls the numlock state. Toggling the
+keypad functionality on and off can become a royal pain. So, Speakup
+gives you a simple way to get at an alternative set of key mappings for
+your laptop. These are also available by default on desktop systems,
+because Speakup does not know whether it is running on a desktop or
+laptop. So you may choose which set of Speakup keys to use. Some
+system administrators may have chosen to compile Speakup for a desktop
+system without this set of alternate key bindings, but these details are
+beyond the scope of this manual. To use the caps lock for its normal
+purpose, hold the shift key while toggling the caps lock on and off. We
+should note here, that holding the caps lock key and pressing the z key
+will toggle the alternate j k l keypad on and off.
+
+4. Keys and Their Assigned Commands
+
+In this section, we'll go through a list of all the speakup keys and
+commands. You can also get a list of commands and assigned keys from
+the help system.
+
+The following list was taken from the speakupmap.map file. Key
+assignments are on the left of the equal sign, and the associated
+Speakup commands are on the right. The designation "spk" means to press
+and hold the speakup key, a.k.a. keypad insert, a.k.a. caps lock, while

+ spk key_9 = speakup_cut
+spk key_8 = speakup_paste
+shift spk key_m = say_first_char
+ ctrl spk key_semicolon = say_last_char
+
+5. The Speakup Sys System
+
+The Speakup screen reader also creates a speakup subdirectory as a part
+of the sys system.
+
+As a convenience, run as root
+
+ln -s /sys/accessibility/speakup /speakup
+
+to directly access speakup parameters from /speakup.
+You can see these entries by typing the command:
+
+ls -1 /speakup/*
+
+If you issue the above ls command, you will get back something like
+this:
+
+/speakup/attrib_bleep
+/speakup/bell_pos
+/speakup/bleep_time
+/speakup/bleeps
+/speakup/cursor_time
+/speakup/delimiters
+/speakup/ex_num
+/speakup/key_echo
+/speakup/keymap
+/speakup/no_interrupt
+/speakup/punc_all
+/speakup/punc_level
+/speakup/punc_most
+/speakup/punc_some
+/speakup/reading_punc
+/speakup/repeats
+/speakup/say_control
+/speakup/say_word_ctl
+/speakup/silent
+/speakup/spell_delay
+/speakup/synth
+/speakup/synth_direct
+/speakup/version
+
+/speakup/i18n:
+announcements
+characters
+chartab
+colors
+ctl_keys
+formatted
+function_names
+key_names
+states
+
+/speakup/soft:
+caps_start
+caps_stop
+delay_time
+direct
+freq
+full_time
+jiffy_delta
+pitch
+inflection
+punct
+rate
+tone
+trigger_time
+voice
+vol
+
+Notice the two subdirectories of /speakup: /speakup/i18n and
+/speakup/soft.
+The i18n subdirectory is described in a later section.
+The files under /speakup/soft represent settings that are specific to the
+driver for the software synthesizer. If you use the LiteTalk, your
+synthesizer-specific settings would be found in /speakup/ltlk. In other words,
+a subdirectory named /speakup/KWD is created to hold parameters specific
+to the device whose keyword is KWD.
+These parameters include volume, rate, pitch, and others.
+
+In addition to using the Speakup hot keys to change such things as
+volume, pitch, and rate, you can also echo values to the appropriate
+entry in the /speakup directory. This is very useful, since it
+lets you control Speakup parameters from within a script. How you
+would write such scripts is somewhat beyond the scope of this manual,
+but I will include a couple of simple examples here to give you a
+general idea of what such scripts can do.
+
+Suppose for example, that you wanted to control both the punctuation
+level and the reading punctuation level at the same time. For
+simplicity, we'll call them punc0, punc1, punc2, and punc3. The scripts
+might look something like this:
+
+#!/bin/bash
+# punc0
+# set punc and reading punc levels to 0
+echo 0 >/speakup/punc_level
+echo 0 >/speakup/reading_punc
+echo Punctuation level set to 0.
+
+#!/bin/bash
+# punc1
+# set punc and reading punc levels to 1
+echo 1 >/speakup/punc_level
+echo 1 >/speakup/reading_punc
+echo Punctuation level set to 1.
+
+#!/bin/bash
+# punc2
+# set punc and reading punc levels to 2
+echo 2 >/speakup/punc_level
+echo 2 >/speakup/reading_punc
+echo Punctuation level set to 2.
+
+#!/bin/bash
+# punc3
+# set punc and reading punc levels to 3
+echo 3 >/speakup/punc_level
+echo 3 >/speakup/reading_punc
+echo Punctuation level set to 3.
+
+If you were to store these four small scripts in a directory in your
+path, perhaps /usr/local/bin, and set the permissions to 755 with the
+chmod command, then you could change the default reading punc and
+punctuation levels at the same time by issuing just one command. For
+example, if you were to execute the punc3 command at your shell prompt,
+then the reading punc and punc level would both get set to 3.
+
+I should note that the above scripts were written to work with bash, but
+regardless of which shell you use, you should be able to do something
+similar.
+
+The Speakup sys system also has another interesting use. You can echo
+Speakup parameters into the sys system in a script during system
+startup, and speakup will return to your preferred parameters every time
+the system is rebooted.
+
+Most of the Speakup sys parameters can be manipulated by a regular user
+on the system. However, there are a few parameters that are dangerous
+enough that they should only be manipulated by the root user on your
+system. There are even some parameters that are read only, and cannot
+be written to at all. For example, the version entry in the Speakup
+sys system is read only. This is because there is no reason for a user
+to tamper with the version number which is reported by Speakup. Doing
+an ls -l on /speakup/version will return this:
+
+-r--r--r-- 1 root root 0 Mar 21 13:46 /speakup/version
+
+As you can see, the version entry in the Speakup sys system is read
+only, is owned by root, and belongs to the root group. Doing a cat of
+/speakup/version will display the Speakup version number, like
+this:
+
+cat /speakup/version
+Speakup v-2.00 CVS: Thu Oct 21 10:38:21 EDT 2004
+synth dtlk version 1.1
+
+The display shows the Speakup version number, along with the version
+number of the driver for the current synthesizer.
+
+Looking at entries in the Speakup sys system can be useful in many
+ways. For example, you might wish to know what level your volume is set
+at. You could type:
+
+cat /speakup/KWD/vol
+# Replace KWD with the keyword for your synthesizer, E.G., ltlk for LiteTalk.
+5
+
+The number five which comes back is the level at which the synthesizer
+volume is set at.
+
+All the entries in the Speakup sys system are readable, some are
+writable by root only, and some are writable by everyone. Unless you
+know what you are doing, you should probably leave the ones that are
+writable by root only alone. Most of the names are self explanatory.
+Vol for controlling volume, pitch for pitch, inflection for pitch range, rate
+for controlling speaking rate, etc. If you find one you aren't sure about, you
+can post a query on the Speakup list.
+
+6. Changing Synthesizers
+
+It is possible to change to a different synthesizer while speakup is
+running. In other words, it is not necessary to reboot the system
+in order to use a different synthesizer. You can simply echo the
+synthesizer keyword to the /speakup/synth sys entry.
+Depending on your situation, you may wish to echo none to the synth
+sys entry, to disable speech while one synthesizer is disconnected and
+a second one is connected in its place. Then echo the keyword for the
+new synthesizer into the synth sys entry in order to start speech
+with the newly connected synthesizer. See the list of synthesizer
+keywords in section 1 to find the keyword which matches your synth.
+
+7. Loading modules
+
+As mentioned earlier, Speakup can either be completely compiled into the
+kernel, with the exception of the help module, or it can be compiled as
+a series of modules. When compiled as modules, Speakup will only be
+able to speak some of the bootup messages if your system administrator
+has configured the system to load the modules at boo time. The modules
+can be loaded after the file systems have been checked and mounted, or
+from an initrd. There is a third possibility. Speakup can be compiled
+with some components built into the kernel, and others as modules. As
+we'll see in the next section, this is particularly useful when you are
+working with software synthesizers.
+
+If Speakup is completely compiled as modules, then you must use the
+modprobe command to load Speakup. You do this by loading the module for
+the synthesizer driver you wish to use. The driver modules are all
+named speakup_<keyword>, where <keyword> is the keyword for the
+synthesizer you want. So, in order to load the driver for the DecTalk
+Express, you would type the following command:
+
+modprobe speakup_dectlk
+
+Issuing this command would load the DecTalk Express driver and all other
+related Speakup modules necessary to get Speakup up and running.
+
+To completely unload Speakup, again presuming that it is entirely built
+as modules, you would give the command:
+
+modprobe -r speakup_dectlk
+
+The above command assumes you were running a DecTalk Express. If you
+were using a different synth, then you would substitute its keyword in
+place of dectlk.
+
+If you have multiple drivers loaded, you need to unload all of them, in
+order to completely unload Speakup.
+For example, if you have loaded both the dectlk and ltlk drivers, use the
+command:
+modprobe -r speakup_dectlk speakup_ltlk
+
+You cannot unload the driver for software synthesizers when a user-space
+daemon is using /dev/softsynth. First, kill the daemon. Next, remove
+the driver with the command:
+modprobe -r speakup_soft
+
+Now, suppose we have a situation where the main Speakup component
+is built into the kernel, and some or all of the drivers are built as
+modules. Since the main part of Speakup is compiled into the kernel, a
+partial Speakup sys system has been created which we can take advantage
+of by simply echoing the synthesizer keyword into the
+/speakup/synth sys entry. This will cause the kernel to
+automatically load the appropriate driver module, and start Speakup
+talking. To switch to another synth, just echo a new keyword to the
+synth sys entry. For example, to load the DoubleTalk LT driver,
+you would type:
+
+echo ltlk >/speakup/synth
+
+You can use the modprobe -r command to unload driver modules, regardless
+of whether the main part of Speakup has been built into the kernel or
+not.
+
+8. Using Software Synthesizers
+
+Using a software synthesizer requires that some other software be
+installed and running on your system. For this reason, software
+synthesizers are not available for use at bootup, or during a system
+installation process.
+There are two freely-available solutions for software speech: Espeakup and
+Speech Dispatcher.
+These are described in subsections 8.1 and 8.2, respectively.
+
+During the rest of this section, we assume that speakup_soft is either
+built in to your kernel, or loaded as a module.
+
+If your system does not have udev installed , before you can use a
+software synthesizer, you must have created the /dev/softsynth device.
+If you have not already done so, issue the following commands as root:
+
+cd /dev
+mknod softsynth c 10 26
+
+While we are at it, we might just as well create the /dev/synth device,
+which can be used to let user space programs send information to your
+synthesizer. To create /dev/synth, change to the /dev directory, and
+issue the following command as root:
+
+mknod synth c 10 25
+
+of both.
+
+8.1. Espeakup
+
+Espeakup is a connector between Speakup and the eSpeak software synthesizer.
+Espeakup may already be available as a package for your distribution
+of Linux. If it is not packaged, you need to install it manually.
+You can find it in the contrib/ subdirectory of the Speakup sources.
+The filename is espeakup-$VERSION.tar.bz2, where $VERSION
+depends on the current release of Espeakup. The Speakup 3.1.2 source
+ships with version 0.71 of Espeakup.
+The README file included with the Espeakup sources describes the process
+of manual installation.
+
+Assuming that Espeakup is installed, either by the user or by the distributor,
+follow these steps to use it.
+
+Tell Speakup to use the "soft driver:
+echo soft > /speakup/synth
+
+Finally, start the espeakup program. There are two ways to do it.
+Both require root privileges.
+
+If Espeakup was installed as a package for your Linux distribution,
+you probably have a distribution-specific script that controls the operation
+of the daemon. Look for a file named espeakup under /etc/init.d or
+/etc/rc.d. Execute the following command with root privileges:
+/etc/init.d/espeakup start
+Replace init.d with rc.d, if your distribution uses scripts located under
+/etc/rc.d.
+Your distribution will also have a procedure for starting daemons at
+boot-time, so it is possible to have software speech as soon as user-space
+daemons are started by the bootup scripts.
+These procedures are not described in this document.
+
+If you built Espeakup manually, the "make install" step placed the binary
+under /usr/bin.
+Run the following command as root:
+/usr/bin/espeakup
+Espeakup should start speaking.
+
+8.2. Speech Dispatcher
+
+For this option, you must have a package called
+Speech Dispatcher running on your system, and it must be configured to
+work with one of its supported software synthesizers.
+
+Two open source synthesizers you might use are Flite and Festival. You
+might also choose to purchase the Software DecTalk from Fonix Sales Inc.
+If you run a google search for Fonix, you'll find their web site.
+
+You can obtain a copy of Speech Dispatcher from free(b)soft at
+http://www.freebsoft.org/. Follow the installation instructions that
+come with Speech Dispatcher in order to install and configure Speech
+Dispatcher. You can check out the web site for your Linux distribution
+in order to get a copy of either Flite or Festival. Your Linux
+distribution may also have a precompiled Speech Dispatcher package.
+
+Once you've installed, configured, and tested Speech Dispatcher with your
+chosen software synthesizer, you still need one more piece of software
+in order to make things work. You need a package called speechd-up.
+You get it from the free(b)soft web site mentioned above. After you've
+compiled and installed speechd-up, you are almost ready to begin using
+your software synthesizer.
+
+Now you can begin using your software synthesizer. In order to do so,
+echo the soft keyword to the synth sys entry like this:
+
+echo soft >/speakup/synth
+
+Next run the speechd_up command like this:
+
+speechd_up &
+
+Your synth should now start talking, and you should be able to adjust
+the pitch, rate, etc.
+
+9. Using The DecTalk PC Card
+
+The DecTalk PC card is an ISA card that is inserted into one of the ISA
+slots in your computer. It requires that the DecTalk PC software be
+installed on your computer, and that the software be loaded onto the
+Dectalk PC card before it can be used.
+
+You can get the dec_pc.tgz file from the linux-speakup.org site. The
+dec_pc.tgz file is in the ~ftp/pub/linux/speakup directory.
+
+After you have downloaded the dec_pc.tgz file, untar it in your home
+directory, and read the Readme file in the newly created dec_pc
+directory.
+
+The easiest way to get the software working is to copy the entire dec_pc
+directory into /user/local/lib. To do this, su to root in your home
+directory, and issue the command:
+
+cp dec_pc /usr/local/lib
+
+You will need to copy the dtload command from the dec_pc directory to a
+directory in your path. Either /usr/bin or /usr/local/bin is a good
+choice.
+
+You can now run the dtload command in order to load the DecTalk PC
+software onto the card. After you have done this, echo the decpc
+keyword to the synth entry in the sys system like this:
+
+echo decpc >/speakup/synth
+
+Your DecTalk PC should start talking, and then you can adjust the pitch,
+rate, volume, voice, etc. The voice entry in the Speakup sys system
+will accept a number from 0 through 7 for the DecTalk PC synthesizer,
+which will give you access to some of the DecTalk voices.
+
+10. Using Cursor Tracking
+
+In Speakup version 2.0 and later, cursor tracking is turned on by
+default. This means that when you are using an editor, Speakup will
+automatically speak characters as you move left and right with the
+cursor keys, and lines as you move up and down with the cursor keys.
+This is the traditional sort of cursor tracking.
+Recent versions of Speakup provide two additional ways to control the
+text that is spoken when the cursor is moved:
+"highlight tracking" and "read window."
+They are described later in this section.
+Sometimes, these modes get in your way, so you can disable cursor tracking
+altogether.
+
+You may select among the various forms of cursor tracking using the keypad
+asterisk key.
+Each time you press this key, a new mode is selected, and Speakup speaks
+the name of the new mode. The names for the four possible states of cursor
+tracking are: "cursoring on", "highlight tracking", "read window",
+and "cursoring off." The keypad asterisk key moves through the list of
+modes in a circular fashion.
+
+If highlight tracking is enabled, Speakup tracks highlighted text,
+rather than the cursor itself. When you move the cursor with the arrow keys,
+Speakup speaks the currently highlighted information.
+This is useful when moving through various menus and dialog boxes.
+If cursor tracking isn't helping you while navigating a menu,
+try highlight tracking.
+
+With the "read window" variety of cursor tracking, you can limit the text
+that Speakup speaks by specifying a window of interest on the screen.
+See section 15 for a description of the process of defining windows.
+When you move the cursor via the arrow keys, Speakup only speaks
+the contents of the window. This is especially helpful when you are hearing
+superfluous speech. Consider the following example.
+
+Suppose that you are at a shell prompt. You use bash, and you want to
+explore your command history using the up and down arrow keys. If you
+have enabled cursor tracking, you will hear two pieces of information.
+Speakup speaks both your shell prompt and the current entry from the
+command history. You may not want to hear the prompt repeated
+each time you move, so you can silence it by specifying a window. Find
+the last line of text on the screen. Clear the current window by pressing
+the key combination speakup f3. Use the review cursor to find the first
+character that follows your shell prompt. Press speakup + f2 twice, to
+define a one-line window. The boundaries of the window are the
+character following the shell prompt and the end of the line. Now, cycle
+through the cursor tracking modes using keypad asterisk, until Speakup
+says "read window." Move through your history using your arrow keys.
+You will notice that Speakup no longer speaks the redundant prompt.
+
+Some folks like to turn cursor tracking off while they are using the
+lynx web browser. You definitely want to turn cursor tracking off when
+you are using the alsamixer application. Otherwise, you won't be able
+to hear your mixer settings while you are using the arrow keys.
+
+11. Cut and Paste
+
+One of Speakup's more useful features is the ability to cut and paste
+text on the screen. This means that you can capture information from a
+program, and paste that captured text into a different place in the
+program, or into an entirely different program, which may even be
+running on a different console.
+
+For example, in this manual, we have made references to several web
+sites. It would be nice if you could cut and paste these urls into your
+web browser. Speakup does this quite nicely. Suppose you wanted to
+past the following url into your browser:
+
+http://linux-speakup.org/
+
+Use the speakup review keys to position the reading cursor on the first
+character of the above url. When the reading cursor is in position,
+press the keypad slash key once. Speakup will say, "mark". Next,
+position the reading cursor on the rightmost character of the above
+url. Press the keypad slash key once again to actually cut the text
+from the screen. Speakup will say, "cut". Although we call this
+cutting, Speakup does not actually delete the cut text from the screen.
+It makes a copy of the text in a special buffer for later pasting.
+
+Now that you have the url cut from the screen, you can paste it into
+your browser, or even paste the url on a command line as an argument to
+your browser.
+
+Suppose you want to start lynx and go to the Speakup site.
+
+You can switch to a different console with the alt left and right
+arrows, or you can switch to a specific console by typing alt and a
+function key. These are not Speakup commands, just standard Linux
+console capabilities.
+
+Once you've changed to an appropriate console, and are at a shell prompt,
+type the word lynx, followed by a space. Now press and hold the speakup
+key, while you type the keypad slash character. The url will be pasted
+onto the command line, just as though you had typed it in. Press the
+enter key to execute the command.
+
+The paste buffer will continue to hold the cut information, until a new
+mark and cut operation is carried out. This means you can paste the cut
+information as many times as you like before doing another cut
+operation.
+
+You are not limited to cutting and pasting only one line on the screen.
+You can also cut and paste rectangular regions of the screen. Just
+position the reading cursor at the top left corner of the text to be
+cut, mark it with the keypad slash key, then position the reading cursor
+at the bottom right corner of the region to be cut, and cut it with the
+keypad slash key.
+
+12. Changing the Pronunciation of Characters
+
+Through the /speakup/i18n/characters sys entry, Speakup gives you the
+ability to change how Speakup pronounces a given character. You could,
+for example, change how some punctuation characters are spoken. You can
+even change how Speakup will pronounce certain letters.
+
+You may, for example, wish to change how Speakup pronounces the z
+character. The author of Speakup, Kirk Reiser, is Canadian, and thus
+believes that the z should be pronounced zed. If you are an American,
+you might wish to use the zee pronunciation instead of zed. You can
+change the pronunciation of both the upper and lower case z with the
+following two commands:
+
+echo 90 zee >/speakup/characters
+echo 122 zee >/speakup/characters
+
+Let's examine the parts of the two previous commands. They are issued
+at the shell prompt, and could be placed in a startup script.
+
+The word echo tells the shell that you want to have it display the
+string of characters that follow the word echo. If you were to just
+type:
+
+echo hello.
+
+You would get the word hello printed on your screen as soon as you
+pressed the enter key. In this case, we are echoing strings that we
+want to be redirected into the sys system.
+
+The numbers 90 and 122 in the above echo commands are the ascii numeric
+values for the upper and lower case z, the characters we wish to change.
+
+The string zee is the pronunciation that we want Speakup to use for the
+upper and lower case z.
+
+The > symbol redirects the output of the echo command to a file, just
+like in DOS, or at the Windows command prompt.
+
+And finally, /speakup/i18n/characters is the file entry in the sys system
+where we want the output to be directed. Speakup looks at the numeric
+value of the character we want to change, and inserts the pronunciation
+string into an internal table.
+
+You can look at the whole table with the following command:
+
+cat /speakup/i18n/characters
+
+Speakup will then print out the entire character pronunciation table. I
+won't display it here, but leave you to look at it at your convenience.
+
+13. Mapping Keys
+
+Speakup has the capability of allowing you to assign or "map" keys to
+internal Speakup commands. This section necessarily assumes you have a
+Linux kernel source tree installed, and that it has been patched and
+configured with Speakup. How you do this is beyond the scope of this
+manual. For this information, visit the Speakup web site at
+http://linux-speakup.org/. The reason you'll need the kernel source
+tree patched with Speakup is that the genmap utility you'll need for
+processing keymaps is in the
+/usr/src/linux-<version_number>/drivers/char/speakup directory. The
+<version_number> in the above directory path is the version number of
+the Linux source tree you are working with.
+
+So ok, you've gone off and gotten your kernel source tree, and patched
+and configured it. Now you can start manipulating keymaps.
+
+You can either use the
+/usr/src/linux-<version_number>/drivers/char/speakup/speakupmap.map file
+included with the Speakup source, or you can cut and paste the copy in
+section 4 into a separate file. If you use the one in the Speakup
+source tree, make sure you make a backup of it before you start making
+changes. You have been warned!
+
+Suppose that you want to swap the key assignments for the Speakup
+say_last_char and the Speakup say_first_char commands. The
+speakupmap.map lists the key mappings for these two commands as follows:
+
+spk key_pageup = say_first_char
+spk key_pagedown = say_last_char
+
+You can edit your copy of the speakupmap.map file and swap the command
+names on the right side of the = (equals) sign. You did make a backup,
+right? The new keymap lines would look like this:
+
+spk key_pageup = say_last_char
+spk key_pagedown = say_first_char
+
+After you edit your copy of the speakupmap.map file, save it under a new
+file name, perhaps newmap.map. Then exit your editor and return to the
+shell prompt.
+
+You are now ready to load your keymap with your swapped key assignments.
+ Assuming that you saved your new keymap as the file newmap.map, you
+would load your keymap into the sys system like this:
+
+/usr/src/linux-<version_number>/drivers/char/speakup/genmap newmap.map
+>/speakup/keymap
+
+Remember to substitute your kernel version number for the
+<version_number> in the above command. Also note that although the
+above command wrapped onto two lines in this document, you should type
+it all on one line.
+
+Your say first and say last characters should now be swapped. Pressing
+speakup pagedown should read you the first non-whitespace character on
+the line your reading cursor is in, and pressing speakup pageup should
+read you the last character on the line your reading cursor is in.
+
+You should note that these new mappings will only stay in effect until
+you reboot, or until you load another keymap.
+
+One final warning. If you try to load a partial map, you will quickly
+find that all the mappings you didn't include in your file got deleted
+from the working map. Be extremely careful, and always make a backup!
+You have been warned!
+
+14. Internationalizing Speakup
+
+Speakup indicates various conditions to the user by speaking messages.
+For instance, when you move to the left edge of the screen with the
+review keys, Speakup says, "left."
+Prior to version 3.1.0 of Speakup, all of these messages were in English,
+and they could not be changed. If you used a non-English synthesizer,
+you still heard English messages, such as "left" and "cursoring on."
+In version 3.1.0 or higher, one may load translations for the various
+messages via the /sys filesystem.
+
+The directory /speakup/i18n contains several collections of messages.
+Each group of messages is stored in its own file.
+The following section lists all of these files, along with a brief description
+of each.
+
+14.1. Files Under the i18n Subdirectory
+
+* announcements:
+This file contains various general announcements, most of which cannot
+be categorized. You will find messages such as "You killed Speakup",
+"I'm alive", "leaving help", "parked", "unparked", and others.
+You will also find the names of the screen edges and cursor tracking modes
+here.
+
+* characters:
+See section 12 for a description of this file.
+
+* chartab:
+See section 12. Unlike the rest of the files in the i18n subdirectory,
+this one does not contain messages to be spoken.
+
+* colors:
+When you use the "say attributes" function, Speakup says the name of the
+foreground and background colors. These names come from the i18n/colors
+file.
+
+* ctl_keys:
+Here, you will find names of control keys. These are used with Speakup's
+say_control feature.
+
+* formatted:
+This group of messages contains embedded formatting codes, to specify
+the type and width of displayed data. If you change these, you must
+preserve all of the formatting codes, and they must appear in the order
+used by the default messages.
+
+* function_names:
+Here, you will find a list of names for Speakup functions. These are used
+by the help system. For example, suppose that you have activated help mode,
+and you pressed keypad 3. Speakup says:
+"keypad 3 is character, say next."
+The message "character, say next" names a Speakup function, and it
+comes from this function_names file.
+
+* key_names:
+Again, key_names is used by Speakup's help system. In the previous
+example, Speakup said that you pressed "keypad 3."
+This name came from the key_names file.
+
+* states:
+This file contains names for key states.
+Again, these are part of the help system. For instance, if you had pressed
+speakup + keypad 3, you would hear:
+"speakup keypad 3 is go to bottom edge."
+The speakup key is depressed, so the name of the key state is speakup.
+This part of the message comes from the states collection.
+
+14.2. Loading Your Own Messages
+
+The files under the i18n subdirectory all follow the same format.
+They consist of lines, with one message per line.
+Each message is represented by a number, followed by the text of the message.
+The number is the position of the message in the given collection.
+For example, if you view the file /speakup/i18n/colors, you will see the
+following list:
+
+0 black
+1 blue
+2 green
+3 cyan
+4 red
+5 magenta
+6 yellow
+7 white
+8 grey
+
+You can change one message, or you can change a whole group.
+To load a whole collection of messages from a new source, simply use
+the cp command:
+cp ~/my_colors /speakup/i18n/colors
+You can change an individual message with the echo command,
+as shown in the following example.
+
+The Spanish name for the color blue is azul.
+Looking at the colors file, we see that the name "blue" is at position 1
+within the colors group. Let's change blue to azul:
+echo '1 azul' > /speakup/i18n/colors
+The next time that Speakup says message 1 from the colors group, it will
+say "azul", rather than "blue."
+
+In the future, translations into various languages will be made available,
+and most users will just load the files necessary for their language.
+
+14.3. No Support for Non-Western-European Languages
+
+As of the current release, Speakup only supports Western European languages.
+Support for the extended characters used by languages outside of the Western
+European family of languages is a work in progress.
+
+15. Using Speakup's Windowing Capability
+
+Speakup has the capability of defining and manipulating windows on the
+screen. Speakup uses the term "Window", to mean a user defined area of
+the screen. The key strokes for defining and manipulating Speakup
+windows are as follows:
+
+speakup + f2 -- Set the bounds of the window.
+Speakup + f3 -- clear the current window definition.
+speakup + f4 -- Toggle window silence on and off.
+speakup + keypad plus -- Say the currently defined window.
+
+These capabilities are useful for tracking a certain part of the screen
+without rereading the whole screen, or for silencing a part of the
+screen that is constantly changing, such as a clock or status line.
+
+There is no way to save these window settings, and you can only have one
+window defined for each virtual console. There is also no way to have
+windows automatically defined for specific applications.
+
+In order to define a window, use the review keys to move your reading
+cursor to the beginning of the area you want to define. Then press
+speakup + f2. Speakup will tell you that the window starts at the
+indicated row and column position. Then move the reading cursor to the
+end of the area to be defined as a window, and press speakup + f2 again.
+ If there is more than one line in the window, Speakup will tell you
+that the window ends at the indicated row and column position. If there
+is only one line in the window, then Speakup will tell you that the
+window is the specified line on the screen. If you are only defining a
+one line window, you can just press speakup + f2 twice after placing the
+reading cursor on the line you want to define as a window. It is not
+necessary to position the reading cursor at the end of the line in order
+to define the whole line as a window.
+
+16. Tools for Controlling Speakup
+
+The speakup distribution includes extra tools (in the tools directory)
+which were written to make speakup easier to use. This section will
+briefly describe the use of these tools.
+
+16.1. Speakupconf
+
+speakupconf began life as a contribution from Steve Holmes, a member of
+the speakup community. We would like to thank him for his work on the
+early versions of this project.
+
+This script may be installed as part of your linux distribution, but if
+it isn't, the recommended places to put it are /usr/local/bin or
+/usr/bin. This script can be run by any user, so it does not require
+root privileges.
+
+Speakupconf allows you to save and load your Speakup settings. It works
+by reading and writing the /sys files described above.
+
+The directory that speakupconf uses to store your settings depends on
+whether it is run from the root account. If you execute speakupconf as
+root, it uses the directory /etc/speakup. Otherwise, it uses the directory
+~/.speakup, where ~ is your home directory.
+Anyone who needs to use Speakup from your console can load his own custom
+settings with this script.
+
+speakupconf takes one required argument: load or save.
+Use the command
+speakupconf save
+to save your Speakup settings, and
+speakupconf load
+to load them into Speakup.
+A second argument may be specified to use an alternate directory to
+load or save the speakup parameters.
+
+16.2. Talkwith
+
+Charles Hallenbeck, another member of the speakup community, wrote the
+initial versions of this script, and we would also like to thank him for
+his work on it.
+
+This script needs root privileges to run, so if it is not installed as
+part of your linux distribution, the recommended places to install it
+are /usr/local/sbin or /usr/sbin.
+
+Talkwith allows you to switch synthesizers on the fly. It takes a synthesizer
+name as an argument. For instance,
+talkwith dectlk
+causes Speakup to use the DecTalk Express. If you wish to switch to a
+software synthesizer, you must also indicate which daemon you wish to
+use. There are two possible choices:
+spd and espeakup. spd is an abbreviation for speechd-up.
+If you wish to use espeakup for software synthesis, give the command
+talkwith soft espeakup
+To use speechd-up, type:
+talkwith soft spd
+Any arguments that follow the name of the daemon are passed to the daemon
+when it is invoked. For instance:
+talkwith espeakup --default-voice=fr
+causes espeakup to use the French voice.
+Note that talkwith must always be executed with root privileges.
+
+Talkwith does not attempt to load your settings after the new
+synthesizer is activated. You can use speakupconf to load your settings
+if desired.

+
+
+ Copyright (C) 2000,2001,2002 Free Software Foundation, Inc.
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+0. PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document "free" in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of "copyleft", which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+
+1. APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The "Document", below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as "you". You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A "Modified Version" of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A "Secondary Section" is a named appendix or a front-matter section of
+the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall subject
+(or to related matters) and contains nothing that could fall directly
+within that overall subject. (Thus, if the Document is in part a
+textbook of mathematics, a Secondary Section may not explain any
+mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The "Invariant Sections" are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The "Cover Texts" are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A "Transparent" copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not "Transparent" is called "Opaque".
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, LaTeX input format, SGML
+or XML using a publicly available DTD, and standard-conforming simple
+HTML, PostScript or PDF designed for human modification. Examples of
+transparent image formats include PNG, XCF and JPG. Opaque formats
+include proprietary formats that can be read and edited only by
+proprietary word processors, SGML or XML for which the DTD and/or
+processing tools are not generally available, and the
+machine-generated HTML, PostScript or PDF produced by some word
+processors for output purposes only.
+
+The "Title Page" means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, "Title Page" means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section "Entitled XYZ" means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as "Acknowledgements",
+"Dedications", "Endorsements", or "History".) To "Preserve the Title"
+of such a section when you modify the Document means that it remains a
+section "Entitled XYZ" according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+
+2. VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+3. COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+
+4. MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+A. Use in the Title Page (and on the covers, if any) a title distinct
+ from that of the Document, and from those of previous versions
+ (which should, if there were any, be listed in the History section
+ of the Document). You may use the same title as a previous version
+ if the original publisher of that version gives permission.
+B. List on the Title Page, as authors, one or more persons or entities
+ responsible for authorship of the modifications in the Modified
+ Version, together with at least five of the principal authors of the
+ Document (all of its principal authors, if it has fewer than five),
+ unless they release you from this requirement.
+C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+D. Preserve all the copyright notices of the Document.
+E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+F. Include, immediately after the copyright notices, a license notice
+ giving the public permission to use the Modified Version under the
+ terms of this License, in the form shown in the Addendum below.
+G. Preserve in that license notice the full lists of Invariant Sections
+ and required Cover Texts given in the Document's license notice.
+H. Include an unaltered copy of this License.
+I. Preserve the section Entitled "History", Preserve its Title, and add
+ to it an item stating at least the title, year, new authors, and
+ publisher of the Modified Version as given on the Title Page. If
+ there is no section Entitled "History" in the Document, create one
+ stating the title, year, authors, and publisher of the Document as
+ given on its Title Page, then add an item describing the Modified
+ Version as stated in the previous sentence.
+J. Preserve the network location, if any, given in the Document for
+ public access to a Transparent copy of the Document, and likewise
+ the network locations given in the Document for previous versions
+ it was based on. These may be placed in the "History" section.
+ You may omit a network location for a work that was published at
+ least four years before the Document itself, or if the original
+ publisher of the version it refers to gives permission.
+K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section all
+ the substance and tone of each of the contributor acknowledgements
+ and/or dedications given therein.
+L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section titles.
+M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+N. Do not retitle any existing section to be Entitled "Endorsements"
+ or to conflict in title with any Invariant Section.
+O. Preserve any Warranty Disclaimers.
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled "Endorsements", provided it contains
+nothing but endorsements of your Modified Version by various
+parties--for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+
+5. COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled "History"
+in the various original documents, forming one section Entitled
+"History"; likewise combine any sections Entitled "Acknowledgements",
+and any sections Entitled "Dedications". You must delete all sections
+Entitled "Endorsements".
+
+
+6. COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+7. AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an "aggregate" if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+
+8. TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled "Acknowledgements",
+"Dedications", or "History", the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+
+9. TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License. Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License. However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+
+10. FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+https://www.gnu.org/copyleft/.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License "or any later version" applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation.
+
+
+ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+ Copyright (c) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
+ A copy of the license is included in the section entitled "GNU
+ Free Documentation License".
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with the
+ Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.
+
+The End.

+========================

- Value type: <u32 array>
- Definition: Used for scaling the channel input signal before the signal is
- fed to VADC. The configuration for this node is to know the
- pre-determined ratio and use it for post scaling. Select one from
- the following options.
- <1 1>, <1 3>, <1 4>, <1 6>, <1 20>, <1 8>, <10 81>, <1 10>
- If property is not found default value depending on chip will be used.
-
-- qcom,ratiometric:
- Usage: optional
- Value type: <empty>
- Definition: Channel calibration type.
- - For compatible property "qcom,spmi-vadc", if this property is
- specified VADC will use the VDD reference (1.8V) and GND for
- channel calibration. If property is not found, channel will be
- calibrated with 0.625V and 1.25V reference channels, also
- known as absolute calibration.
- - For compatible property "qcom,spmi-adc5" and "qcom,spmi-adc-rev2",
- if this property is specified VADC will use the VDD reference
- (1.875V) and GND for channel calibration. If property is not found,
- channel will be calibrated with 0V and 1.25V reference channels,
- also known as absolute calibration.
-
-- qcom,hw-settle-time:
- Usage: optional
- Value type: <u32>
- Definition: Time between AMUX getting configured and the ADC starting
- conversion. The 'hw_settle_time' is an index used from valid values
- and programmed in hardware to achieve the hardware settling delay.
- - For compatible property "qcom,spmi-vadc" and "qcom,spmi-adc-rev2",
- Delay = 100us * (hw_settle_time) for hw_settle_time < 11,
- and 2ms * (hw_settle_time - 10) otherwise.
- Valid values are: 0, 100, 200, 300, 400, 500, 600, 700, 800,
- 900 us and 1, 2, 4, 6, 8, 10 ms.
- If property is not found, channel will use 0us.
- - For compatible property "qcom,spmi-adc5", delay = 15us for
- value 0, 100us * (value) for values < 11,
- and 2ms * (value - 10) otherwise.
- Valid values are: 15, 100, 200, 300, 400, 500, 600, 700, 800,
- 900 us and 1, 2, 4, 6, 8, 10 ms
- Certain controller digital versions have valid values of
- 15, 100, 200, 300, 400, 500, 600, 700, 1, 2, 4, 8, 16, 32, 64, 128 ms
- If property is not found, channel will use 15us.
-
-- qcom,avg-samples:
- Usage: optional
- Value type: <u32>
- Definition: Number of samples to be used for measurement.
- Averaging provides the option to obtain a single measurement
- from the ADC that is an average of multiple samples. The value
- selected is 2^(value).
- - For compatible property "qcom,spmi-vadc", valid values
- are: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
- If property is not found, 1 sample will be used.
- - For compatible property "qcom,spmi-adc5" and "qcom,spmi-adc-rev2",
- valid values are: 1, 2, 4, 8, 16
- If property is not found, 1 sample will be used.
-
-NOTE:
-
-For compatible property "qcom,spmi-vadc" following channels, also known as
-reference point channels, are used for result calibration and their channel
-configuration nodes should be defined:
-VADC_REF_625MV and/or VADC_SPARE1(based on PMIC version) VADC_REF_1250MV,
-VADC_GND_REF and VADC_VDD_VADC.

+description: -|
+ The IMI D&D RDACM20 and RDACM21 are GMSL-compatible camera designed for
+ automotive applications.
+
+ The RDACM20 camera module encloses a Maxim Integrated MAX9271 GMSL serializer,
+ coupled with an OV10635 image sensor and an embedded MCU. Both the MCU and
+ the image sensor are connected to the serializer local I2C bus and are
+ accessible by the host SoC by direct addressing.
+
+ The RDACM21 camera module encloses the same serializer, coupled with an
+ OV10640 image sensor and an OV490 ISP. Only the OV490 ISP is interfaced to
+ the serializer local I2C bus while the image sensor is not accessible from
+ the host SoC.
+
+ They both connect to a remote GMSL endpoint through a coaxial cable.

+ +---------------+ +--------------------------------+
+
+ Both camera modules serialize video data generated by the embedded camera
+ sensor on the GMSL serial channel to a remote GMSL de-serializer. They also
+ receive and transmit I2C messages encapsulated and transmitted on the GMSL
+ bidirectional control channel.
+
+ All I2C traffic received on the GMSL link not directed to the serializer is
+ propagated on the local I2C bus to the remote device there connected. All the
+ I2C traffic generated on the local I2C bus not directed to the serializer is
+ propagated to the remote de-serializer encapsulated in the GMSL control
+ channel.
+
+ The RDACM20 and RDACM21 DT node should be a direct child of the GMSL
+ deserializer's I2C bus corresponding to the GMSL link that the camera is
+ attached to.

+ The MAX9286 deserializer receives video data on up to 4 Gigabit Multimedia
+ Serial Links (GMSL) and outputs them on a CSI-2 D-PHY port using up to 4 data

+
+ In addition to video data, the GMSL links carry a bidirectional control

+ serializer will output it on a local I2C bus. In the other direction all I2C
+ traffic received over GMSL by the MAX9286 is output on the local I2C bus.

-Renesas R-Car Frame Compression Processor (FCP)
------------------------------------------------
-
-The FCP is a companion module of video processing modules in the Renesas R-Car
-Gen3 and RZ/G2 SoCs. It provides data compression and decompression, data
-caching, and conversion of AXI transactions in order to reduce the memory
-bandwidth.
-
-There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and FCP
-for FDP (FCPF). Their configuration and behaviour depend on the module they

+
+description: |
+ The Xilinx MIPI CSI-2 Receiver Subsystem is used to capture MIPI CSI-2
+ traffic from compliant camera sensors and send the output as AXI4 Stream
+ video data for image processing.
+ The subsystem consists of a MIPI D-PHY in slave mode which captures the
+ data packets. This is passed along the MIPI CSI-2 Rx IP which extracts the
+ packet data. The optional Video Format Bridge (VFB) converts this data to
+ AXI4 Stream video data.
+ For more details, please refer to PG232 Xilinx MIPI CSI-2 Receiver Subsystem.
+ Please note that this bindings includes only the MIPI CSI-2 Rx controller
+ and Video Format Bridge and not D-PHY.

+
+description: |
+ The FMC2 functional block makes the interface with: synchronous and
+ asynchronous static devices (such as PSNOR, PSRAM or other memory-mapped
+ peripherals) and NAND flash memories.
+ Its main purposes are:
+ - to translate AXI transactions into the appropriate external device
+ protocol
+ - to meet the access time requirements of the external devices
+ All external devices share the addresses, data and control signals with the
+ controller. Each external device is accessed by means of a unique Chip
+ Select. The FMC2 performs only one access at a time to an external device.

-Google's ChromeOS EC is a Cortex-M device which talks to the AP and
-implements various function such as keyboard and battery charging.
-
-The EC can be connect through various means (I2C, SPI, LPC, RPMSG) and the
-compatible string used depends on the interface. Each connection method has
-its own driver which connects to the top level interface-agnostic EC driver.
-Other Linux driver (such as cros-ec-keyb for the matrix keyboard) connect to
-the top-level driver.
-
-Required properties (I2C):
-- compatible: "google,cros-ec-i2c"
-- reg: I2C slave address
-
-Required properties (SPI):
-- compatible: "google,cros-ec-spi"
-- reg: SPI chip select
-
-Required properties (RPMSG):
-- compatible: "google,cros-ec-rpmsg"
-
-Optional properties (SPI):
-- google,cros-ec-spi-pre-delay: Some implementations of the EC need a little
- time to wake up from sleep before they can receive SPI transfers at a high
- clock rate. This property specifies the delay, in usecs, between the
- assertion of the CS to the start of the first clock pulse.
-- google,cros-ec-spi-msg-delay: Some implementations of the EC require some
- additional processing time in order to accept new transactions. If the delay
- between transactions is not long enough the EC may not be able to respond
- properly to subsequent transactions and cause them to hang. This property
- specifies the delay, in usecs, introduced between transactions to account
- for the time required by the EC to get back into a state in which new data
- can be accepted.
-
-Required properties (LPC):
-- compatible: "google,cros-ec-lpc"
-- reg: List of (IO address, size) pairs defining the interface uses
-
-Optional properties (all):
-- google,has-vbc-nvram: Some implementations of the EC include a small
- nvram space used to store verified boot context data. This boolean flag
- is used to specify whether this nvram is present or not.

-Ingenic XBurst pin controller
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-For the XBurst SoCs, pin control is tightly bound with GPIO ports. All pins may
-be used as GPIOs, multiplexed device functions are configured within the
-GPIO port configuration registers and it is typical to refer to pins using the
-naming scheme "PxN" where x is a character identifying the GPIO port with
-which the pin is associated and N is an integer from 0 to 31 identifying the
-pin within that GPIO port. For example PA0 is the first pin in GPIO port A, and
-PB31 is the last pin in GPIO port B. The jz4740, the x1000 and the x1830
-contains 4 GPIO ports, PA to PD, for a total of 128 pins. The jz4760, the
-jz4770 and the jz4780 contains 6 GPIO ports, PA to PF, for a total of 192 pins.
-
-
-Required properties:
---------------------
-

- - "ingenic,x1500-pinctrl"
- - "ingenic,x1830-pinctrl"
- - reg: Address range of the pinctrl registers.
-
-
-Required properties for sub-nodes (GPIO chips):
------------------------------------------------
-
- - compatible: Must contain one of:
- - "ingenic,jz4740-gpio"
- - "ingenic,jz4760-gpio"
- - "ingenic,jz4770-gpio"
- - "ingenic,jz4780-gpio"
- - "ingenic,x1000-gpio"
- - "ingenic,x1830-gpio"
- - reg: The GPIO bank number.
- - interrupt-controller: Marks the device node as an interrupt controller.
- - interrupts: Interrupt specifier for the controllers interrupt.
- - #interrupt-cells: Should be 2. Refer to
- ../interrupt-controller/interrupts.txt for more details.
- - gpio-controller: Marks the device node as a GPIO controller.
- - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
- cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
- GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
- - gpio-ranges: Range of pins managed by the GPIO controller. Refer to
- ../gpio/gpio.txt for more details.

-STMicroelectronics Multi-Function eXpander (STMFX) GPIO expander bindings
-
-ST Multi-Function eXpander (STMFX) offers up to 24 GPIOs expansion.
-Please refer to ../mfd/stmfx.txt for STMFX Core bindings.
-
-Required properties:
-- compatible: should be "st,stmfx-0300-pinctrl".
-- #gpio-cells: should be <2>, the first cell is the GPIO number and the second
- cell is the gpio flags in accordance with <dt-bindings/gpio/gpio.h>.
-- gpio-controller: marks the device as a GPIO controller.
-- #interrupt-cells: should be <2>, the first cell is the GPIO number and the
- second cell is the interrupt flags in accordance with
- <dt-bindings/interrupt-controller/irq.h>.
-- interrupt-controller: marks the device as an interrupt controller.
-- gpio-ranges: specifies the mapping between gpio controller and pin
- controller pins. Check "Concerning gpio-ranges property" below.
-Please refer to ../gpio/gpio.txt.
-
-Please refer to pinctrl-bindings.txt for pin configuration.
-
-Required properties for pin configuration sub-nodes:
-- pins: list of pins to which the configuration applies.
-
-Optional properties for pin configuration sub-nodes (pinconf-generic ones):
-- bias-disable: disable any bias on the pin.
-- bias-pull-up: the pin will be pulled up.
-- bias-pull-pin-default: use the pin-default pull state.
-- bias-pull-down: the pin will be pulled down.
-- drive-open-drain: the pin will be driven with open drain.
-- drive-push-pull: the pin will be driven actively high and low.
-- output-high: the pin will be configured as an output driving high level.
-- output-low: the pin will be configured as an output driving low level.
-
-Note that STMFX pins[15:0] are called "gpio[15:0]", and STMFX pins[23:16] are
-called "agpio[7:0]". Example, to refer to pin 18 of STMFX, use "agpio2".
-
-Concerning gpio-ranges property:
-- if all STMFX pins[24:0] are available (no other STMFX function in use), you
- should use gpio-ranges = <&stmfx_pinctrl 0 0 24>;
-- if agpio[3:0] are not available (STMFX Touchscreen function in use), you
- should use gpio-ranges = <&stmfx_pinctrl 0 0 16>, <&stmfx_pinctrl 20 20 4>;
-- if agpio[7:4] are not available (STMFX IDD function in use), you
- should use gpio-ranges = <&stmfx_pinctrl 0 0 20>;
-

-
- stmfx: stmfx@42 {

-Renesas RZ/A2 combined Pin and GPIO controller
-
-The Renesas SoCs of the RZ/A2 series feature a combined Pin and GPIO controller.
-Pin multiplexing and GPIO configuration is performed on a per-pin basis.
-Each port features up to 8 pins, each of them configurable for GPIO
-function (port mode) or in alternate function mode.
-Up to 8 different alternate function modes exist for each single pin.
-
-Pin controller node
--------------------
-
-Required properties:
- - compatible: shall be:
- - "renesas,r7s9210-pinctrl": for RZ/A2M
- - reg
- Address base and length of the memory area where the pin controller
- hardware is mapped to.
- - gpio-controller
- This pin controller also controls pins as GPIO
- - #gpio-cells
- Must be 2
- - gpio-ranges
- Expresses the total number of GPIO ports/pins in this SoC
-
-Example: Pin controller node for RZ/A2M SoC (r7s9210)
-
- pinctrl: pin-controller@fcffe000 {
- compatible = "renesas,r7s9210-pinctrl";
- reg = <0xfcffe000 0x1000>;
-
- gpio-controller;
- #gpio-cells = <2>;
- gpio-ranges = <&pinctrl 0 0 176>;
- };
-
-Sub-nodes
----------
-
-The child nodes of the pin controller designate pins to be used for
-specific peripheral functions or as GPIO.
-
-- Pin multiplexing sub-nodes:
- A pin multiplexing sub-node describes how to configure a set of
- (or a single) pin in some desired alternate function mode.
- The values for the pinmux properties are a combination of port name, pin
- number and the desired function index. Use the RZA2_PINMUX macro located
- in include/dt-bindings/pinctrl/r7s9210-pinctrl.h to easily define these.
- For assigning GPIO pins, use the macro RZA2_PIN also in r7s9210-pinctrl.h
- to express the desired port pin.
-
- Required properties:
- - pinmux:
- integer array representing pin number and pin multiplexing configuration.
- When a pin has to be configured in alternate function mode, use this
- property to identify the pin by its global index, and provide its
- alternate function configuration number along with it.
- When multiple pins are required to be configured as part of the same
- alternate function they shall be specified as members of the same
- argument list of a single "pinmux" property.
- Helper macros to ease assembling the pin index from its position
- (port where it sits on and pin number) and alternate function identifier
- are provided by the pin controller header file at:
- <dt-bindings/pinctrl/r7s9210-pinctrl.h>
- Integers values in "pinmux" argument list are assembled as:
- ((PORT * 8 + PIN) | MUX_FUNC << 16)
-
- Example: Board specific pins configuration
-
- &pinctrl {
- /* Serial Console */
- scif4_pins: serial4 {
- pinmux = <RZA2_PINMUX(PORT9, 0, 4)>, /* TxD4 */
- <RZA2_PINMUX(PORT9, 1, 4)>; /* RxD4 */
- };
- };
-
- Example: Assigning a GPIO:
-
- leds {
- status = "okay";
- compatible = "gpio-leds";
-
- led0 {
- /* P6_0 */
- gpios = <&pinctrl RZA2_PIN(PORT6, 0) GPIO_ACTIVE_HIGH>;
- };
- };

+description:
+ The Renesas SoCs of the RZ/A2 series feature a combined Pin and GPIO
+ controller.
+ Pin multiplexing and GPIO configuration is performed on a per-pin basis.
+ Each port features up to 8 pins, each of them configurable for GPIO function
+ (port mode) or in alternate function mode.
+ Up to 8 different alternate function modes exist for each single pin.

-In smart batteries, these are typically stored in non-volatile memory
-on a fuel gauge chip. The battery node should be used where there is
-no appropriate non-volatile memory, or it is unprogrammed/incorrect.
-
-Upstream dts files should not include battery nodes, unless the battery
-represented cannot easily be replaced in the system by one of a
-different type. This prevents unpredictable, potentially harmful,
-behavior should a replacement that changes the battery type occur
-without a corresponding update to the dtb.

+description: |
+ The TI K3 family of SoCs usually have one or more TI DSP Core sub-systems
+ that are used to offload some of the processor-intensive tasks or algorithms,
+ for achieving various system level goals.
+
+ These processor sub-systems usually contain additional sub-modules like
+ L1 and/or L2 caches/SRAMs, an Interrupt Controller, an external memory
+ controller, a dedicated local power/sleep controller etc. The DSP processor
+ cores in the K3 SoCs are usually either a TMS320C66x CorePac processor or a
+ TMS320C71x CorePac processor.
+
+ Each DSP Core sub-system is represented as a single DT node. Each node has a
+ number of required or optional properties that enable the OS running on the
+ host processor (Arm CorePac) to perform the device management of the remote
+ processor and to communicate with the remote processor.

-Required properties:
-- compatible : should be one of the following:
- "socionext,uniphier-ld11-aio"
- "socionext,uniphier-ld20-aio"
- "socionext,uniphier-pxs2-aio"
-- reg : offset and length of the register set for the device.
-- interrupts : should contain I2S or S/PDIF interrupt.
-- pinctrl-names : should be "default".
-- pinctrl-0 : defined I2S signal pins for an external codec chip.
-- clock-names : should include following entries:
- "aio"
-- clocks : a list of phandle, should contain an entry for each
- entry in clock-names.
-- reset-names : should include following entries:

-* Thermal Framework Device Tree descriptor
-
-This file describes a generic binding to provide a way of
-defining hardware thermal structure using device tree.
-A thermal structure includes thermal zones and their components,
-such as trip points, polling intervals, sensors and cooling devices
-binding descriptors.
-
-The target of device tree thermal descriptors is to describe only
-the hardware thermal aspects. The thermal device tree bindings are
-not about how the system must control or which algorithm or policy
-must be taken in place.
-
-There are five types of nodes involved to describe thermal bindings:
-- thermal sensors: devices which may be used to take temperature
- measurements.
-- cooling devices: devices which may be used to dissipate heat.
-- trip points: describe key temperatures at which cooling is recommended. The
- set of points should be chosen based on hardware limits.
-- cooling maps: used to describe links between trip points and cooling devices;
-- thermal zones: used to describe thermal data within the hardware;
-
-The following is a description of each of these node types.
-
-* Thermal sensor devices
-
-Thermal sensor devices are nodes providing temperature sensing capabilities on
-thermal zones. Typical devices are I2C ADC converters and bandgaps. These are
-nodes providing temperature data to thermal zones. Thermal sensor devices may
-control one or more internal sensors.
-
-Required property:
-- #thermal-sensor-cells: Used to provide sensor device specific information
- Type: unsigned while referring to it. Typically 0 on thermal sensor
- Size: one cell nodes with only one sensor, and at least 1 on nodes
- with several internal sensors, in order
- to identify uniquely the sensor instances within
- the IC. See thermal zone binding for more details
- on how consumers refer to sensor devices.
-
-* Cooling device nodes
-
-Cooling devices are nodes providing control on power dissipation. There
-are essentially two ways to provide control on power dissipation. First
-is by means of regulating device performance, which is known as passive
-cooling. A typical passive cooling is a CPU that has dynamic voltage and
-frequency scaling (DVFS), and uses lower frequencies as cooling states.
-Second is by means of activating devices in order to remove
-the dissipated heat, which is known as active cooling, e.g. regulating
-fan speeds. In both cases, cooling devices shall have a way to determine
-the state of cooling in which the device is.
-
-Any cooling device has a range of cooling states (i.e. different levels
-of heat dissipation). For example a fan's cooling states correspond to
-the different fan speeds possible. Cooling states are referred to by
-single unsigned integers, where larger numbers mean greater heat
-dissipation. The precise set of cooling states associated with a device
-should be defined in a particular device's binding.
-For more examples of cooling devices, refer to the example sections below.
-
-Required properties:
-- #cooling-cells: Used to provide cooling device specific information
- Type: unsigned while referring to it. Must be at least 2, in order
- Size: one cell to specify minimum and maximum cooling state used
- in the reference. The first cell is the minimum
- cooling state requested and the second cell is
- the maximum cooling state requested in the reference.
- See Cooling device maps section below for more details
- on how consumers refer to cooling devices.
-
-* Trip points
-
-The trip node is a node to describe a point in the temperature domain
-in which the system takes an action. This node describes just the point,
-not the action.
-
-Required properties:
-- temperature: An integer indicating the trip temperature level,
- Type: signed in millicelsius.
- Size: one cell
-
-- hysteresis: A low hysteresis value on temperature property (above).
- Type: unsigned This is a relative value, in millicelsius.
- Size: one cell
-
-- type: a string containing the trip type. Expected values are:
- "active": A trip point to enable active cooling
- "passive": A trip point to enable passive cooling
- "hot": A trip point to notify emergency
- "critical": Hardware not reliable.
- Type: string
-
-* Cooling device maps
-
-The cooling device maps node is a node to describe how cooling devices
-get assigned to trip points of the zone. The cooling devices are expected
-to be loaded in the target system.
-
-Required properties:
-- cooling-device: A list of phandles of cooling devices with their specifiers,
- Type: phandle + referring to which cooling devices are used in this
- cooling specifier binding. In the cooling specifier, the first cell
- is the minimum cooling state and the second cell
- is the maximum cooling state used in this map.
-- trip: A phandle of a trip point node within the same thermal
- Type: phandle of zone.
- trip point node
-
-Optional property:
-- contribution: The cooling contribution to the thermal zone of the
- Type: unsigned referred cooling device at the referred trip point.
- Size: one cell The contribution is a ratio of the sum
- of all cooling contributions within a thermal zone.
-
-Note: Using the THERMAL_NO_LIMIT (-1UL) constant in the cooling-device phandle
-limit specifier means:
-(i) - minimum state allowed for minimum cooling state used in the reference.
-(ii) - maximum state allowed for maximum cooling state used in the reference.
-Refer to include/dt-bindings/thermal/thermal.h for definition of this constant.
-
-* Thermal zone nodes
-
-The thermal zone node is the node containing all the required info
-for describing a thermal zone, including its cooling device bindings. The
-thermal zone node must contain, apart from its own properties, one sub-node
-containing trip nodes and one sub-node containing all the zone cooling maps.
-
-Required properties:
-- polling-delay: The maximum number of milliseconds to wait between polls
- Type: unsigned when checking this thermal zone.
- Size: one cell
-
-- polling-delay-passive: The maximum number of milliseconds to wait
- Type: unsigned between polls when performing passive cooling.
- Size: one cell
-
-- thermal-sensors: A list of thermal sensor phandles and sensor specifier
- Type: list of used while monitoring the thermal zone.
- phandles + sensor
- specifier
-
-- trips: A sub-node which is a container of only trip point nodes
- Type: sub-node required to describe the thermal zone.
-
-Optional property:
-- cooling-maps: A sub-node which is a container of only cooling device
- Type: sub-node map nodes, used to describe the relation between trips
- and cooling devices.
-
-- coefficients: An array of integers (one signed cell) containing
- Type: array coefficients to compose a linear relation between
- Elem size: one cell the sensors listed in the thermal-sensors property.
- Elem type: signed Coefficients defaults to 1, in case this property
- is not specified. A simple linear polynomial is used:
- Z = c0 * x0 + c1 * x1 + ... + c(n-1) * x(n-1) + cn.
-
- The coefficients are ordered and they match with sensors
- by means of sensor ID. Additional coefficients are
- interpreted as constant offset.
-
-- sustainable-power: An estimate of the sustainable power (in mW) that the
- Type: unsigned thermal zone can dissipate at the desired
- Size: one cell control temperature. For reference, the
- sustainable power of a 4'' phone is typically
- 2000mW, while on a 10'' tablet is around
- 4500mW.
-
-Note: The delay properties are bound to the maximum dT/dt (temperature
-derivative over time) in two situations for a thermal zone:
-(i) - when passive cooling is activated (polling-delay-passive); and
-(ii) - when the zone just needs to be monitored (polling-delay) or
-when active cooling is activated.
-
-The maximum dT/dt is highly bound to hardware power consumption and dissipation
-capability. The delays should be chosen to account for said max dT/dt,
-such that a device does not cross several trip boundaries unexpectedly
-between polls. Choosing the right polling delays shall avoid having the
-device in temperature ranges that may damage the silicon structures and
-reduce silicon lifetime.
-
-* The thermal-zones node
-
-The "thermal-zones" node is a container for all thermal zone nodes. It shall
-contain only sub-nodes describing thermal zones as in the section
-"Thermal zone nodes". The "thermal-zones" node appears under "/".
-
-* Examples
-
-Below are several examples on how to use thermal data descriptors
-using device tree bindings:
-
-(a) - CPU thermal zone
-
-The CPU thermal zone example below describes how to setup one thermal zone
-using one single sensor as temperature source and many cooling devices and
-power dissipation control sources.

- * all four OPPs can be available to the system. The maximum
- * cooling state is 3, which means only the lowest OPPs (198MHz@0.85V)
- * can be available in the system.

- trip = <&cpu_alert1>;
- cooling-device = <&fan0 5 THERMAL_NO_LIMIT>, <&cpu0 THERMAL_NO_LIMIT THERMAL_NO_LIMIT>;
- };
- };
- };
-};
-
-In the example above, the ADC sensor (bandgap0) at address 0x0000ED00 is
-used to monitor the zone 'cpu-thermal' using its sole sensor. A fan
-device (fan0) is controlled via I2C bus 1, at address 0x48, and has ten
-different cooling states 0-9. It is used to remove the heat out of
-the thermal zone 'cpu-thermal' using its cooling states
-from its minimum to 4, when it reaches trip point 'cpu_alert0'
-at 90C, as an example of active cooling. The same cooling device is used at
-'cpu_alert1', but from 5 to its maximum state. The cpu@0 device is also
-linked to the same thermal zone, 'cpu-thermal', as a passive cooling device,
-using all its cooling states at trip point 'cpu_alert1',
-which is a trip point at 100C. On the thermal zone 'cpu-thermal', at the
-temperature of 125C, represented by the trip point 'cpu_crit', the silicon
-is not reliable anymore.
-
-(b) - IC with several internal sensors
-
-The example below describes how to deploy several thermal zones based off a
-single sensor IC, assuming it has several internal sensors. This is a common
-case on SoC designs with several internal IPs that may need different thermal
-requirements, and thus may have their own sensor to monitor or detect internal
-hotspots in their silicon.

- };
- gpu_crit: gpu-crit {
- temperature = <105000>; /* millicelsius */

- };
- };

- /* each zone within the SoC may have its own trips */

- type = "critical";
- };
- };
-
- cooling-maps {
- /* each zone within the SoC may have its own cooling */
- ...
- };
- };
-};
-
-In the example above, there is one bandgap IC which has the capability to
-monitor three sensors. The hardware has been designed so that sensors are
-placed on different places in the DIE to monitor different temperature
-hotspots: one for CPU thermal zone, one for GPU thermal zone and the
-other to monitor a DSP thermal zone.
-
-Thus, there is a need to assign each sensor provided by the bandgap IC
-to different thermal zones. This is achieved by means of using the
-#thermal-sensor-cells property and using the first cell of the sensor
-specifier as sensor ID. In the example, then, <bandgap 0> is used to
-monitor CPU thermal zone, <bandgap 1> is used to monitor GPU thermal
-zone and <bandgap 2> is used to monitor DSP thermal zone. Each zone
-may be uncorrelated, having its own dT/dt requirements, trips
-and cooling maps.
-
-
-(c) - Several sensors within one single thermal zone
-
-The example below illustrates how to use more than one sensor within
-one thermal zone.
-
-#include <dt-bindings/thermal/thermal.h>
-
-&i2c1 {
- ...
- /*
- * A simple IC with a single temperature sensor.
- */
- adc: sensor@49 {
- ...
- #thermal-sensor-cells = <0>;
- };
-};
-
-ocp {
- ...
- /*
- * A simple IC with a single bandgap temperature sensor.
- */
- bandgap0: bandgap@0000ed00 {
- ...
- #thermal-sensor-cells = <0>;
- };
-};
-
-thermal-zones {
- cpu_thermal: cpu-thermal {
- polling-delay-passive = <250>; /* milliseconds */
- polling-delay = <1000>; /* milliseconds */
-
- thermal-sensors = <&bandgap0>, /* cpu */
- <&adc>; /* pcb north */
-
- /* hotspot = 100 * bandgap - 120 * adc + 484 */
- coefficients = <100 -120 484>;
-
- trips {
- ...
- };
-
- cooling-maps {
- ...
- };
- };
-};
-
-In some cases, there is a need to use more than one sensor to extrapolate
-a thermal hotspot in the silicon. The above example illustrates this situation.
-For instance, it may be the case that a sensor external to CPU IP may be placed
-close to CPU hotspot and together with internal CPU sensor, it is used
-to determine the hotspot. Assuming this is the case for the above example,
-the hypothetical extrapolation rule would be:
- hotspot = 100 * bandgap - 120 * adc + 484
-
-In other context, the same idea can be used to add fixed offset. For instance,
-consider the hotspot extrapolation rule below:
- hotspot = 1 * adc + 6000
-
-In the above equation, the hotspot is always 6C higher than what is read
-from the ADC sensor. The binding would be then:
- thermal-sensors = <&adc>;
-
- /* hotspot = 1 * adc + 6000 */
- coefficients = <1 6000>;
-
-(d) - Board thermal
-
-The board thermal example below illustrates how to setup one thermal zone
-with many sensors and many cooling devices.
-
-#include <dt-bindings/thermal/thermal.h>
-
-&i2c1 {
- ...
- /*
- * An IC with several temperature sensor.

- <&adc_dummy 1>, /* lcd */
- <&adc_dummy 2>; /* back cover */
- /*
- * An array of coefficients describing the sensor
- * linear relation. E.g.:
- * z = c1*x1 + c2*x2 + c3*x3
- */
- coefficients = <1200 -345 890>;
-
- sustainable-power = <2500>;
-
- trips {
- /* Trips are based on resulting linear equation */
- cpu_trip: cpu-trip {
- temperature = <60000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- };
- gpu_trip: gpu-trip {
- temperature = <55000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- }
- lcd_trip: lcp-trip {
- temperature = <53000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "passive";
- };
- crit_trip: crit-trip {
- temperature = <68000>; /* millicelsius */
- hysteresis = <2000>; /* millicelsius */
- type = "critical";
- };
- };
-
- cooling-maps {
- map0 {
- trip = <&cpu_trip>;
- cooling-device = <&cpu0 0 2>;
- contribution = <55>;
- };
- map1 {
- trip = <&gpu_trip>;
- cooling-device = <&gpu0 0 2>;
- contribution = <20>;
- };
- map2 {
- trip = <&lcd_trip>;
- cooling-device = <&lcd0 5 10>;
- contribution = <15>;
- };
- };
- };
-};
-
-The above example is a mix of previous examples, a sensor IP with several internal
-sensors used to monitor different zones, one of them is composed by several sensors and
-with different cooling devices.

+==================================
+NVDIMM Runtime Firmware Activation
+==================================
+
+Some persistent memory devices run a firmware locally on the device /
+"DIMM" to perform tasks like media management, capacity provisioning,
+and health monitoring. The process of updating that firmware typically
+involves a reboot because it has implications for in-flight memory
+transactions. However, reboots are disruptive and at least the Intel
+persistent memory platform implementation, described by the Intel ACPI
+DSM specification [1], has added support for activating firmware at
+runtime.
+
+A native sysfs interface is implemented in libnvdimm to allow platform
+to advertise and control their local runtime firmware activation
+capability.
+
+The libnvdimm bus object, ndbusX, implements an ndbusX/firmware/activate
+attribute that shows the state of the firmware activation as one of 'idle',
+'armed', 'overflow', and 'busy'.
+
+- idle:
+ No devices are set / armed to activate firmware
+
+- armed:
+ At least one device is armed
+
+- busy:
+ In the busy state armed devices are in the process of transitioning
+ back to idle and completing an activation cycle.
+
+- overflow:
+ If the platform has a concept of incremental work needed to perform
+ the activation it could be the case that too many DIMMs are armed for
+ activation. In that scenario the potential for firmware activation to
+ timeout is indicated by the 'overflow' state.
+
+The 'ndbusX/firmware/activate' property can be written with a value of
+either 'live', or 'quiesce'. A value of 'quiesce' triggers the kernel to
+run firmware activation from within the equivalent of the hibernation
+'freeze' state where drivers and applications are notified to stop their
+modifications of system memory. A value of 'live' attempts
+firmware activation without this hibernation cycle. The
+'ndbusX/firmware/activate' property will be elided completely if no
+firmware activation capability is detected.
+
+Another property 'ndbusX/firmware/capability' indicates a value of
+'live' or 'quiesce', where 'live' indicates that the firmware
+does not require or inflict any quiesce period on the system to update
+firmware. A capability value of 'quiesce' indicates that firmware does
+expect and injects a quiet period for the memory controller, but 'live'
+may still be written to 'ndbusX/firmware/activate' as an override to
+assume the risk of racing firmware update with in-flight device and
+application activity. The 'ndbusX/firmware/capability' property will be
+elided completely if no firmware activation capability is detected.
+
+The libnvdimm memory-device / DIMM object, nmemX, implements
+'nmemX/firmware/activate' and 'nmemX/firmware/result' attributes to
+communicate the per-device firmware activation state. Similar to the
+'ndbusX/firmware/activate' attribute, the 'nmemX/firmware/activate'
+attribute indicates 'idle', 'armed', or 'busy'. The state transitions
+from 'armed' to 'idle' when the system is prepared to activate firmware,
+firmware staged + state set to armed, and 'ndbusX/firmware/activate' is
+triggered. After that activation event the nmemX/firmware/result
+attribute reflects the state of the last activation as one of:
+
+- none:
+ No runtime activation triggered since the last time the device was reset
+
+- success:
+ The last runtime activation completed successfully.
+
+- fail:
+ The last runtime activation failed for device-specific reasons.
+
+- not_staged:
+ The last runtime activation failed due to a sequencing error of the
+ firmware image not being staged.
+
+- need_reset:
+ Runtime firmware activation failed, but the firmware can still be
+ activated via the legacy method of power-cycling the system.

-=================================================
-Msc Keyboard Scan Expansion/GPIO Expansion device
-=================================================
-
-What is smsc-ece1099?
-----------------------
-
-The ECE1099 is a 40-Pin 3.3V Keyboard Scan Expansion
-or GPIO Expansion device. The device supports a keyboard
-scan matrix of 23x8. The device is connected to a Master
-via the SMSC BC-Link interface or via the SMBus.
-Keypad scan Input(KSI) and Keypad Scan Output(KSO) signals
-are multiplexed with GPIOs.
-
-Interrupt generation
---------------------
-
-Interrupts can be generated by an edge detection on a GPIO
-pin or an edge detection on one of the bus interface pins.
-Interrupts can also be detected on the keyboard scan interface.
-The bus interrupt pin (BC_INT# or SMBUS_INT#) is asserted if
-any bit in one of the Interrupt Status registers is 1 and
-the corresponding Interrupt Mask bit is also 1.
-
-In order for software to determine which device is the source
-of an interrupt, it should first read the Group Interrupt Status Register
-to determine which Status register group is a source for the interrupt.
-Software should read both the Status register and the associated Mask register,
-then AND the two values together. Bits that are 1 in the result of the AND
-are active interrupts. Software clears an interrupt by writing a 1 to the
-corresponding bit in the Status register.
-
-Communication Protocol
-----------------------
-
-- SMbus slave Interface
- The host processor communicates with the ECE1099 device
- through a series of read/write registers via the SMBus
- interface. SMBus is a serial communication protocol between
- a computer host and its peripheral devices. The SMBus data
- rate is 10KHz minimum to 400 KHz maximum
-
-- Slave Bus Interface
- The ECE1099 device SMBus implementation is a subset of the
- SMBus interface to the host. The device is a slave-only SMBus device.
- The implementation in the device is a subset of SMBus since it
- only supports four protocols.
-
- The Write Byte, Read Byte, Send Byte, and Receive Byte protocols are the
- only valid SMBus protocols for the device.
-
-- BC-LinkTM Interface
- The BC-Link is a proprietary bus that allows communication
- between a Master device and a Companion device. The Master
- device uses this serial bus to read and write registers
- located on the Companion device. The bus comprises three signals,
- BC_CLK, BC_DAT and BC_INT#. The Master device always provides the
- clock, BC_CLK, and the Companion device is the source for an
- independent asynchronous interrupt signal, BC_INT#. The ECE1099
- supports BC-Link speeds up to 24MHz.

-Upgrading I2C Drivers to the new 2.6 Driver Model
-=================================================

-Ben Dooks <ben-linux@fluff.org>

-Introduction
-------------
-
-This guide outlines how to alter existing Linux 2.6 client drivers from
-the old to the new binding methods.
-
-
-Example old-style driver
-------------------------
-
-::
-
- struct example_state {
- struct i2c_client client;
- ....
- };
-
- static struct i2c_driver example_driver;
-
- static unsigned short ignore[] = { I2C_CLIENT_END };
- static unsigned short normal_addr[] = { OUR_ADDR, I2C_CLIENT_END };
-
- I2C_CLIENT_INSMOD;
-
- static int example_attach(struct i2c_adapter *adap, int addr, int kind)
- {
- struct example_state *state;
- struct device *dev = &adap->dev; /* to use for dev_ reports */
- int ret;
-
- state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
- if (state == NULL) {
- dev_err(dev, "failed to create our state\n");
- return -ENOMEM;
- }
-
- example->client.addr = addr;
- example->client.flags = 0;
- example->client.adapter = adap;
-
- i2c_set_clientdata(&state->i2c_client, state);
- strscpy(client->i2c_client.name, "example", sizeof(client->i2c_client.name));
-
- ret = i2c_attach_client(&state->i2c_client);
- if (ret < 0) {
- dev_err(dev, "failed to attach client\n");
- kfree(state);
- return ret;
- }
-
- dev = &state->i2c_client.dev;
-
- /* rest of the initialisation goes here. */
-
- dev_info(dev, "example client created\n");
-
- return 0;
- }
-
- static int example_detach(struct i2c_client *client)
- {
- struct example_state *state = i2c_get_clientdata(client);
-
- i2c_detach_client(client);
- kfree(state);
- return 0;
- }
-
- static int example_attach_adapter(struct i2c_adapter *adap)
- {
- return i2c_probe(adap, &addr_data, example_attach);
- }
-
- static struct i2c_driver example_driver = {
- .driver = {
- .owner = THIS_MODULE,
- .name = "example",
- .pm = &example_pm_ops,
- },
- .attach_adapter = example_attach_adapter,
- .detach_client = example_detach,
- };
-
-
-Updating the client
--------------------
-
-The new style binding model will check against a list of supported
-devices and their associated address supplied by the code registering
-the busses. This means that the driver .attach_adapter and
-.detach_client methods can be removed, along with the addr_data,
-as follows::
-
- - static struct i2c_driver example_driver;
-
- - static unsigned short ignore[] = { I2C_CLIENT_END };
- - static unsigned short normal_addr[] = { OUR_ADDR, I2C_CLIENT_END };
-
- - I2C_CLIENT_INSMOD;
-
- - static int example_attach_adapter(struct i2c_adapter *adap)
- - {
- - return i2c_probe(adap, &addr_data, example_attach);
- - }
-
- static struct i2c_driver example_driver = {
- - .attach_adapter = example_attach_adapter,
- - .detach_client = example_detach,
- }
-
-Add the probe and remove methods to the i2c_driver, as so::
-
- static struct i2c_driver example_driver = {
- + .probe = example_probe,
- + .remove = example_remove,
- }
-
-Change the example_attach method to accept the new parameters
-which include the i2c_client that it will be working with::
-
- - static int example_attach(struct i2c_adapter *adap, int addr, int kind)
- + static int example_probe(struct i2c_client *client,
- + const struct i2c_device_id *id)
-
-Change the name of example_attach to example_probe to align it with the
-i2c_driver entry names. The rest of the probe routine will now need to be
-changed as the i2c_client has already been setup for use.
-
-The necessary client fields have already been setup before
-the probe function is called, so the following client setup
-can be removed::
-
- - example->client.addr = addr;
- - example->client.flags = 0;
- - example->client.adapter = adap;
- -
- - strscpy(client->i2c_client.name, "example", sizeof(client->i2c_client.name));
-
-The i2c_set_clientdata is now::
-
- - i2c_set_clientdata(&state->client, state);
- + i2c_set_clientdata(client, state);
-
-The call to i2c_attach_client is no longer needed, if the probe
-routine exits successfully, then the driver will be automatically
-attached by the core. Change the probe routine as so::
-
- - ret = i2c_attach_client(&state->i2c_client);
- - if (ret < 0) {
- - dev_err(dev, "failed to attach client\n");
- - kfree(state);
- - return ret;
- - }
-
-
-Remove the storage of 'struct i2c_client' from the 'struct example_state'
-as we are provided with the i2c_client in our example_probe. Instead we
-store a pointer to it for when it is needed.
-
-::
-
- struct example_state {
- - struct i2c_client client;
- + struct i2c_client *client;
-
-the new i2c client as so::
-
- - struct device *dev = &adap->dev; /* to use for dev_ reports */
- + struct device *dev = &i2c_client->dev; /* to use for dev_ reports */
-
-And remove the change after our client is attached, as the driver no
-longer needs to register a new client structure with the core::
-
- - dev = &state->i2c_client.dev;
-
-In the probe routine, ensure that the new state has the client stored
-in it::
-
- static int example_probe(struct i2c_client *i2c_client,
- const struct i2c_device_id *id)
- {
- struct example_state *state;
- struct device *dev = &i2c_client->dev;
- int ret;
-
- state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
- if (state == NULL) {
- dev_err(dev, "failed to create our state\n");
- return -ENOMEM;
- }
-
- + state->client = i2c_client;
-
-Update the detach method, by changing the name to _remove and
-to delete the i2c_detach_client call. It is possible that you
-can also remove the ret variable as it is not needed for any
-of the core functions.
-
-::
-
- - static int example_detach(struct i2c_client *client)
- + static int example_remove(struct i2c_client *client)
- {
- struct example_state *state = i2c_get_clientdata(client);
-
- - i2c_detach_client(client);
-
-And finally ensure that we have the correct ID table for the i2c-core
-and other utilities::
-
- + struct i2c_device_id example_idtable[] = {
- + { "example", 0 },
- + { }
- +};
- +
- +MODULE_DEVICE_TABLE(i2c, example_idtable);
-
- static struct i2c_driver example_driver = {
- .driver = {
- .owner = THIS_MODULE,
- .name = "example",
- },
- + .id_table = example_ids,
-
-
-Our driver should now look like this::
-
- struct example_state {
- struct i2c_client *client;
- ....
- };
-
- static int example_probe(struct i2c_client *client,
- const struct i2c_device_id *id)
- {
- struct example_state *state;
- struct device *dev = &client->dev;
-
- state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
- if (state == NULL) {
- dev_err(dev, "failed to create our state\n");
- return -ENOMEM;
- }
-
- state->client = client;
- i2c_set_clientdata(client, state);
-
- /* rest of the initialisation goes here. */
-
- dev_info(dev, "example client created\n");
-
- return 0;
- }
-
- static int example_remove(struct i2c_client *client)
- {
- struct example_state *state = i2c_get_clientdata(client);
-
- kfree(state);
- return 0;
- }
-
- static struct i2c_device_id example_idtable[] = {
- { "example", 0 },
- { }
- };
-
- MODULE_DEVICE_TABLE(i2c, example_idtable);
-
- static struct i2c_driver example_driver = {
- .driver = {
- .owner = THIS_MODULE,
- .name = "example",
- .pm = &example_pm_ops,
- },
- .id_table = example_idtable,
- .probe = example_probe,
- .remove = example_remove,

+Sequence counters with associated locks (``seqcount_LOCKTYPE_t``)
+-----------------------------------------------------------------
+
+As discussed at :ref:`seqcount_t`, sequence count write side critical
+sections must be serialized and non-preemptible. This variant of
+sequence counters associate the lock used for writer serialization at
+initialization time, which enables lockdep to validate that the write
+side critical sections are properly serialized.
+
+This lock association is a NOOP if lockdep is disabled and has neither
+storage nor runtime overhead. If lockdep is enabled, the lock pointer is
+stored in struct seqcount and lockdep's "lock is held" assertions are
+injected at the beginning of the write side critical section to validate
+that it is properly protected.
+
+For lock types which do not implicitly disable preemption, preemption
+protection is enforced in the write side function.
+
+The following sequence counters with associated locks are defined:
+
+ - ``seqcount_spinlock_t``
+ - ``seqcount_raw_spinlock_t``
+ - ``seqcount_rwlock_t``
+ - ``seqcount_mutex_t``
+ - ``seqcount_ww_mutex_t``
+
+The plain seqcount read and write APIs branch out to the specific
+seqcount_LOCKTYPE_t implementation at compile-time. This avoids kernel
+API explosion per each new seqcount LOCKTYPE.
+
+Initialization (replace "LOCKTYPE" with one of the supported locks)::
+
+ /* dynamic */
+ seqcount_LOCKTYPE_t foo_seqcount;
+ seqcount_LOCKTYPE_init(&foo_seqcount, &lock);
+
+ /* static */
+ static seqcount_LOCKTYPE_t foo_seqcount =
+ SEQCNT_LOCKTYPE_ZERO(foo_seqcount, &lock);
+
+ /* C99 struct init */
+ struct {
+ .seq = SEQCNT_LOCKTYPE_ZERO(foo.seq, &lock),
+ } foo;

+
+Performing software stream processing, header generation etc. in the driver
+in order to support this interface is strongly discouraged. In case such

+Querying Capabilities
+=====================
+
+1. To enumerate the set of coded formats supported by the encoder, the
+ client may call :c:func:`VIDIOC_ENUM_FMT` on ``CAPTURE``.
+
+ * The full set of supported formats will be returned, regardless of the
+ format set on ``OUTPUT``.
+
+2. To enumerate the set of supported raw formats, the client may call
+ :c:func:`VIDIOC_ENUM_FMT` on ``OUTPUT``.
+
+ * Only the formats supported for the format currently active on ``CAPTURE``
+ will be returned.
+
+ * In order to enumerate raw formats supported by a given coded format,
+ the client must first set that coded format on ``CAPTURE`` and then
+ enumerate the formats on ``OUTPUT``.
+
+3. The client may use :c:func:`VIDIOC_ENUM_FRAMESIZES` to detect supported
+ resolutions for a given format, passing the desired pixel format in
+ :c:type:`v4l2_frmsizeenum` ``pixel_format``.
+
+ * Values returned by :c:func:`VIDIOC_ENUM_FRAMESIZES` for a coded pixel
+ format will include all possible coded resolutions supported by the
+ encoder for the given coded pixel format.
+
+ * Values returned by :c:func:`VIDIOC_ENUM_FRAMESIZES` for a raw pixel format
+ will include all possible frame buffer resolutions supported by the
+ encoder for the given raw pixel format and coded format currently set on
+ ``CAPTURE``.
+
+4. The client may use :c:func:`VIDIOC_ENUM_FRAMEINTERVALS` to detect supported
+ frame intervals for a given format and resolution, passing the desired pixel
+ format in :c:type:`v4l2_frmsizeenum` ``pixel_format`` and the resolution
+ in :c:type:`v4l2_frmsizeenum` ``width`` and :c:type:`v4l2_frmsizeenum`
+ ``height``.
+
+ * Values returned by :c:func:`VIDIOC_ENUM_FRAMEINTERVALS` for a coded pixel
+ format and coded resolution will include all possible frame intervals
+ supported by the encoder for the given coded pixel format and resolution.
+
+ * Values returned by :c:func:`VIDIOC_ENUM_FRAMEINTERVALS` for a raw pixel
+ format and resolution will include all possible frame intervals supported
+ by the encoder for the given raw pixel format and resolution and for the
+ coded format, coded resolution and coded frame interval currently set on
+ ``CAPTURE``.
+
+ * Support for :c:func:`VIDIOC_ENUM_FRAMEINTERVALS` is optional. If it is
+ not implemented, then there are no special restrictions other than the
+ limits of the codec itself.
+
+5. Supported profiles and levels for the coded format currently set on
+ ``CAPTURE``, if applicable, may be queried using their respective controls
+ via :c:func:`VIDIOC_QUERYCTRL`.
+
+6. Any additional encoder capabilities may be discovered by querying
+ their respective controls.
+
+Initialization
+==============
+
+1. Set the coded format on the ``CAPTURE`` queue via :c:func:`VIDIOC_S_FMT`.
+
+ * **Required fields:**
+
+ ``type``
+ a ``V4L2_BUF_TYPE_*`` enum appropriate for ``CAPTURE``.
+
+ ``pixelformat``
+ the coded format to be produced.
+
+ ``sizeimage``
+ desired size of ``CAPTURE`` buffers; the encoder may adjust it to
+ match hardware requirements.
+
+ ``width``, ``height``
+ ignored (read-only).
+
+ other fields
+ follow standard semantics.
+
+ * **Return fields:**
+
+ ``sizeimage``
+ adjusted size of ``CAPTURE`` buffers.
+
+ ``width``, ``height``
+ the coded size selected by the encoder based on current state, e.g.
+ ``OUTPUT`` format, selection rectangles, etc. (read-only).
+
+ .. important::
+
+ Changing the ``CAPTURE`` format may change the currently set ``OUTPUT``
+ format. How the new ``OUTPUT`` format is determined is up to the encoder
+ and the client must ensure it matches its needs afterwards.
+
+2. **Optional.** Enumerate supported ``OUTPUT`` formats (raw formats for
+ source) for the selected coded format via :c:func:`VIDIOC_ENUM_FMT`.
+
+ * **Required fields:**
+
+ ``type``
+ a ``V4L2_BUF_TYPE_*`` enum appropriate for ``OUTPUT``.
+
+ other fields
+ follow standard semantics.
+
+ * **Return fields:**
+
+ ``pixelformat``
+ raw format supported for the coded format currently selected on
+ the ``CAPTURE`` queue.
+
+ other fields
+ follow standard semantics.
+
+3. Set the raw source format on the ``OUTPUT`` queue via
+ :c:func:`VIDIOC_S_FMT`.
+
+ * **Required fields:**
+
+ ``type``
+ a ``V4L2_BUF_TYPE_*`` enum appropriate for ``OUTPUT``.
+
+ ``pixelformat``
+ raw format of the source.
+
+ ``width``, ``height``
+ source resolution.
+
+ other fields
+ follow standard semantics.
+
+ * **Return fields:**
+
+ ``width``, ``height``
+ may be adjusted to match encoder minimums, maximums and alignment
+ requirements, as required by the currently selected formats, as
+ reported by :c:func:`VIDIOC_ENUM_FRAMESIZES`.
+
+ other fields
+ follow standard semantics.
+
+ * Setting the ``OUTPUT`` format will reset the selection rectangles to their
+ default values, based on the new resolution, as described in the next
+ step.
+
+4. Set the raw frame interval on the ``OUTPUT`` queue via
+ :c:func:`VIDIOC_S_PARM`. This also sets the coded frame interval on the
+ ``CAPTURE`` queue to the same value.
+
+ * ** Required fields:**
+
+ ``type``
+ a ``V4L2_BUF_TYPE_*`` enum appropriate for ``OUTPUT``.
+
+ ``parm.output``
+ set all fields except ``parm.output.timeperframe`` to 0.
+
+ ``parm.output.timeperframe``
+ the desired frame interval; the encoder may adjust it to
+ match hardware requirements.
+
+ * **Return fields:**
+
+ ``parm.output.timeperframe``
+ the adjusted frame interval.
+
+ .. important::
+
+ Changing the ``OUTPUT`` frame interval *also* sets the framerate that
+ the encoder uses to encode the video. So setting the frame interval
+ to 1/24 (or 24 frames per second) will produce a coded video stream
+ that can be played back at that speed. The frame interval for the
+ ``OUTPUT`` queue is just a hint, the application may provide raw
+ frames at a different rate. It can be used by the driver to help
+ schedule multiple encoders running in parallel.
+
+ In the next step the ``CAPTURE`` frame interval can optionally be
+ changed to a different value. This is useful for off-line encoding
+ were the coded frame interval can be different from the rate at
+ which raw frames are supplied.
+
+ .. important::
+
+ ``timeperframe`` deals with *frames*, not fields. So for interlaced
+ formats this is the time per two fields, since a frame consists of
+ a top and a bottom field.
+
+ .. note::
+
+ It is due to historical reasons that changing the ``OUTPUT`` frame
+ interval also changes the coded frame interval on the ``CAPTURE``
+ queue. Ideally these would be independent settings, but that would
+ break the existing API.
+
+5. **Optional** Set the coded frame interval on the ``CAPTURE`` queue via
+ :c:func:`VIDIOC_S_PARM`. This is only necessary if the coded frame
+ interval is different from the raw frame interval, which is typically
+ the case for off-line encoding. Support for this feature is signalled
+ by the :ref:`V4L2_FMT_FLAG_ENC_CAP_FRAME_INTERVAL <fmtdesc-flags>` format flag.
+
+ * ** Required fields:**
+
+ ``type``
+ a ``V4L2_BUF_TYPE_*`` enum appropriate for ``CAPTURE``.
+
+ ``parm.capture``
+ set all fields except ``parm.capture.timeperframe`` to 0.
+
+ ``parm.capture.timeperframe``
+ the desired coded frame interval; the encoder may adjust it to
+ match hardware requirements.
+
+ * **Return fields:**
+
+ ``parm.capture.timeperframe``
+ the adjusted frame interval.
+
+ .. important::
+
+ Changing the ``CAPTURE`` frame interval sets the framerate for the
+ coded video. It does *not* set the rate at which buffers arrive on the
+ ``CAPTURE`` queue, that depends on how fast the encoder is and how
+ fast raw frames are queued on the ``OUTPUT`` queue.
+
+ .. important::
+
+ ``timeperframe`` deals with *frames*, not fields. So for interlaced
+ formats this is the time per two fields, since a frame consists of
+ a top and a bottom field.
+
+ .. note::
+
+ Not all drivers support this functionality, in that case just set
+ the desired coded frame interval for the ``OUTPUT`` queue.
+
+ However, drivers that can schedule multiple encoders based on the
+ ``OUTPUT`` frame interval must support this optional feature.
+
+6. **Optional.** Set the visible resolution for the stream metadata via
+ :c:func:`VIDIOC_S_SELECTION` on the ``OUTPUT`` queue if it is desired
+ to be different than the full OUTPUT resolution.
+
+ * **Required fields:**
+
+ ``type``
+ a ``V4L2_BUF_TYPE_*`` enum appropriate for ``OUTPUT``.
+
+ ``target``
+ set to ``V4L2_SEL_TGT_CROP``.
+
+ ``r.left``, ``r.top``, ``r.width``, ``r.height``
+ visible rectangle; this must fit within the `V4L2_SEL_TGT_CROP_BOUNDS`
+ rectangle and may be subject to adjustment to match codec and
+ hardware constraints.
+
+ * **Return fields:**
+
+ ``r.left``, ``r.top``, ``r.width``, ``r.height``
+ visible rectangle adjusted by the encoder.
+
+ * The following selection targets are supported on ``OUTPUT``:
+
+ ``V4L2_SEL_TGT_CROP_BOUNDS``
+ equal to the full source frame, matching the active ``OUTPUT``
+ format.
+
+ ``V4L2_SEL_TGT_CROP_DEFAULT``
+ equal to ``V4L2_SEL_TGT_CROP_BOUNDS``.
+
+ ``V4L2_SEL_TGT_CROP``
+ rectangle within the source buffer to be encoded into the
+ ``CAPTURE`` stream; defaults to ``V4L2_SEL_TGT_CROP_DEFAULT``.
+
+ .. note::
+
+ A common use case for this selection target is encoding a source
+ video with a resolution that is not a multiple of a macroblock,
+ e.g. the common 1920x1080 resolution may require the source
+ buffers to be aligned to 1920x1088 for codecs with 16x16 macroblock
+ size. To avoid encoding the padding, the client needs to explicitly
+ configure this selection target to 1920x1080.
+
+ .. warning::
+
+ The encoder may adjust the crop/compose rectangles to the nearest
+ supported ones to meet codec and hardware requirements. The client needs
+ to check the adjusted rectangle returned by :c:func:`VIDIOC_S_SELECTION`.
+
+7. Allocate buffers for both ``OUTPUT`` and ``CAPTURE`` via
+ :c:func:`VIDIOC_REQBUFS`. This may be performed in any order.
+
+ * **Required fields:**
+
+ ``count``
+ requested number of buffers to allocate; greater than zero.
+
+ ``type``
+ a ``V4L2_BUF_TYPE_*`` enum appropriate for ``OUTPUT`` or
+ ``CAPTURE``.
+
+ other fields
+ follow standard semantics.
+
+ * **Return fields:**
+
+ ``count``
+ actual number of buffers allocated.
+
+ .. warning::
+
+ The actual number of allocated buffers may differ from the ``count``
+ given. The client must check the updated value of ``count`` after the
+ call returns.
+
+ .. note::
+
+ To allocate more than the minimum number of OUTPUT buffers (for pipeline
+ depth), the client may query the ``V4L2_CID_MIN_BUFFERS_FOR_OUTPUT``
+ control to get the minimum number of buffers required, and pass the
+ obtained value plus the number of additional buffers needed in the
+ ``count`` field to :c:func:`VIDIOC_REQBUFS`.
+
+ Alternatively, :c:func:`VIDIOC_CREATE_BUFS` can be used to have more
+ control over buffer allocation.
+
+ * **Required fields:**
+
+ ``count``
+ requested number of buffers to allocate; greater than zero.
+
+ ``type``
+ a ``V4L2_BUF_TYPE_*`` enum appropriate for ``OUTPUT``.
+
+ other fields
+ follow standard semantics.
+
+ * **Return fields:**
+
+ ``count``
+ adjusted to the number of allocated buffers.
+
+8. Begin streaming on both ``OUTPUT`` and ``CAPTURE`` queues via
+ :c:func:`VIDIOC_STREAMON`. This may be performed in any order. The actual
+ encoding process starts when both queues start streaming.
+
+.. note::
+
+ If the client stops the ``CAPTURE`` queue during the encode process and then
+ restarts it again, the encoder will begin generating a stream independent
+ from the stream generated before the stop. The exact constraints depend
+ on the coded format, but may include the following implications:
+
+ * encoded frames produced after the restart must not reference any
+ frames produced before the stop, e.g. no long term references for
+ H.264/HEVC,
+
+ * any headers that must be included in a standalone stream must be
+ produced again, e.g. SPS and PPS for H.264/HEVC.
+
+Encoding
+========
+
+This state is reached after the `Initialization` sequence finishes
+successfully. In this state, the client queues and dequeues buffers to both
+queues via :c:func:`VIDIOC_QBUF` and :c:func:`VIDIOC_DQBUF`, following the
+standard semantics.
+
+The content of encoded ``CAPTURE`` buffers depends on the active coded pixel
+format and may be affected by codec-specific extended controls, as stated
+in the documentation of each format.
+
+Both queues operate independently, following standard behavior of V4L2 buffer
+queues and memory-to-memory devices. In addition, the order of encoded frames
+dequeued from the ``CAPTURE`` queue may differ from the order of queuing raw
+frames to the ``OUTPUT`` queue, due to properties of the selected coded format,
+e.g. frame reordering.
+
+The client must not assume any direct relationship between ``CAPTURE`` and
+``OUTPUT`` buffers and any specific timing of buffers becoming
+available to dequeue. Specifically:
+
+* a buffer queued to ``OUTPUT`` may result in more than one buffer produced on
+ ``CAPTURE`` (for example, if returning an encoded frame allowed the encoder
+ to return a frame that preceded it in display, but succeeded it in the decode
+ order; however, there may be other reasons for this as well),
+
+* a buffer queued to ``OUTPUT`` may result in a buffer being produced on
+ ``CAPTURE`` later into encode process, and/or after processing further
+ ``OUTPUT`` buffers, or be returned out of order, e.g. if display
+ reordering is used,
+
+* buffers may become available on the ``CAPTURE`` queue without additional
+ buffers queued to ``OUTPUT`` (e.g. during drain or ``EOS``), because of the
+ ``OUTPUT`` buffers queued in the past whose encoding results are only
+ available at later time, due to specifics of the encoding process,
+
+* buffers queued to ``OUTPUT`` may not become available to dequeue instantly
+ after being encoded into a corresponding ``CAPTURE`` buffer, e.g. if the
+ encoder needs to use the frame as a reference for encoding further frames.
+
+.. note::
+
+ To allow matching encoded ``CAPTURE`` buffers with ``OUTPUT`` buffers they
+ originated from, the client can set the ``timestamp`` field of the
+ :c:type:`v4l2_buffer` struct when queuing an ``OUTPUT`` buffer. The
+ ``CAPTURE`` buffer(s), which resulted from encoding that ``OUTPUT`` buffer
+ will have their ``timestamp`` field set to the same value when dequeued.
+
+ In addition to the straightforward case of one ``OUTPUT`` buffer producing
+ one ``CAPTURE`` buffer, the following cases are defined:
+
+ * one ``OUTPUT`` buffer generates multiple ``CAPTURE`` buffers: the same
+ ``OUTPUT`` timestamp will be copied to multiple ``CAPTURE`` buffers,
+
+ * the encoding order differs from the presentation order (i.e. the
+ ``CAPTURE`` buffers are out-of-order compared to the ``OUTPUT`` buffers):
+ ``CAPTURE`` timestamps will not retain the order of ``OUTPUT`` timestamps.
+
+.. note::
+
+ To let the client distinguish between frame types (keyframes, intermediate
+ frames; the exact list of types depends on the coded format), the
+ ``CAPTURE`` buffers will have corresponding flag bits set in their
+ :c:type:`v4l2_buffer` struct when dequeued. See the documentation of
+ :c:type:`v4l2_buffer` and each coded pixel format for exact list of flags
+ and their meanings.
+
+Should an encoding error occur, it will be reported to the client with the level
+of details depending on the encoder capabilities. Specifically:
+
+* the ``CAPTURE`` buffer (if any) that contains the results of the failed encode
+ operation will be returned with the ``V4L2_BUF_FLAG_ERROR`` flag set,
+
+* if the encoder is able to precisely report the ``OUTPUT`` buffer(s) that triggered
+ the error, such buffer(s) will be returned with the ``V4L2_BUF_FLAG_ERROR`` flag
+ set.
+
+.. note::
+
+ If a ``CAPTURE`` buffer is too small then it is just returned with the
+ ``V4L2_BUF_FLAG_ERROR`` flag set. More work is needed to detect that this
+ error occurred because the buffer was too small, and to provide support to
+ free existing buffers that were too small.
+
+In case of a fatal failure that does not allow the encoding to continue, any
+further operations on corresponding encoder file handle will return the -EIO
+error code. The client may close the file handle and open a new one, or
+alternatively reinitialize the instance by stopping streaming on both queues,
+releasing all buffers and performing the Initialization sequence again.
+
+Encoding Parameter Changes
+==========================
+
+The client is allowed to use :c:func:`VIDIOC_S_CTRL` to change encoder
+parameters at any time. The availability of parameters is encoder-specific
+and the client must query the encoder to find the set of available controls.
+
+The ability to change each parameter during encoding is encoder-specific, as
+per the standard semantics of the V4L2 control interface. The client may
+attempt to set a control during encoding and if the operation fails with the
+-EBUSY error code, the ``CAPTURE`` queue needs to be stopped for the
+configuration change to be allowed. To do this, it may follow the `Drain`
+sequence to avoid losing the already queued/encoded frames.
+
+The timing of parameter updates is encoder-specific, as per the standard
+semantics of the V4L2 control interface. If the client needs to apply the
+parameters exactly at specific frame, using the Request API
+(:ref:`media-request-api`) should be considered, if supported by the encoder.
+
+Drain
+=====
+
+To ensure that all the queued ``OUTPUT`` buffers have been processed and the
+related ``CAPTURE`` buffers are given to the client, the client must follow the
+drain sequence described below. After the drain sequence ends, the client has
+received all encoded frames for all ``OUTPUT`` buffers queued before the
+sequence was started.
+
+1. Begin the drain sequence by issuing :c:func:`VIDIOC_ENCODER_CMD`.
+
+ * **Required fields:**
+
+ ``cmd``
+ set to ``V4L2_ENC_CMD_STOP``.
+
+ ``flags``
+ set to 0.
+
+ ``pts``
+ set to 0.
+
+ .. warning::
+
+ The sequence can be only initiated if both ``OUTPUT`` and ``CAPTURE``
+ queues are streaming. For compatibility reasons, the call to
+ :c:func:`VIDIOC_ENCODER_CMD` will not fail even if any of the queues is
+ not streaming, but at the same time it will not initiate the `Drain`
+ sequence and so the steps described below would not be applicable.
+
+2. Any ``OUTPUT`` buffers queued by the client before the
+ :c:func:`VIDIOC_ENCODER_CMD` was issued will be processed and encoded as
+ normal. The client must continue to handle both queues independently,
+ similarly to normal encode operation. This includes:
+
+ * queuing and dequeuing ``CAPTURE`` buffers, until a buffer marked with the
+ ``V4L2_BUF_FLAG_LAST`` flag is dequeued,
+
+ .. warning::
+
+ The last buffer may be empty (with :c:type:`v4l2_buffer`
+ ``bytesused`` = 0) and in that case it must be ignored by the client,
+ as it does not contain an encoded frame.
+
+ .. note::
+
+ Any attempt to dequeue more ``CAPTURE`` buffers beyond the buffer
+ marked with ``V4L2_BUF_FLAG_LAST`` will result in a -EPIPE error from
+ :c:func:`VIDIOC_DQBUF`.
+
+ * dequeuing processed ``OUTPUT`` buffers, until all the buffers queued
+ before the ``V4L2_ENC_CMD_STOP`` command are dequeued,
+
+ * dequeuing the ``V4L2_EVENT_EOS`` event, if the client subscribes to it.
+
+ .. note::
+
+ For backwards compatibility, the encoder will signal a ``V4L2_EVENT_EOS``
+ event when the last frame has been encoded and all frames are ready to be
+ dequeued. It is deprecated behavior and the client must not rely on it.
+ The ``V4L2_BUF_FLAG_LAST`` buffer flag should be used instead.
+
+3. Once all ``OUTPUT`` buffers queued before the ``V4L2_ENC_CMD_STOP`` call are
+ dequeued and the last ``CAPTURE`` buffer is dequeued, the encoder is stopped
+ and it will accept, but not process any newly queued ``OUTPUT`` buffers
+ until the client issues any of the following operations:
+
+ * ``V4L2_ENC_CMD_START`` - the encoder will not be reset and will resume
+ operation normally, with all the state from before the drain,
+
+ * a pair of :c:func:`VIDIOC_STREAMOFF` and :c:func:`VIDIOC_STREAMON` on the
+ ``CAPTURE`` queue - the encoder will be reset (see the `Reset` sequence)
+ and then resume encoding,
+
+ * a pair of :c:func:`VIDIOC_STREAMOFF` and :c:func:`VIDIOC_STREAMON` on the
+ ``OUTPUT`` queue - the encoder will resume operation normally, however any
+ source frames queued to the ``OUTPUT`` queue between ``V4L2_ENC_CMD_STOP``
+ and :c:func:`VIDIOC_STREAMOFF` will be discarded.
+
+.. note::
+
+ Once the drain sequence is initiated, the client needs to drive it to
+ completion, as described by the steps above, unless it aborts the process by
+ issuing :c:func:`VIDIOC_STREAMOFF` on any of the ``OUTPUT`` or ``CAPTURE``
+ queues. The client is not allowed to issue ``V4L2_ENC_CMD_START`` or
+ ``V4L2_ENC_CMD_STOP`` again while the drain sequence is in progress and they
+ will fail with -EBUSY error code if attempted.
+
+ For reference, handling of various corner cases is described below:
+
+ * In case of no buffer in the ``OUTPUT`` queue at the time the
+ ``V4L2_ENC_CMD_STOP`` command was issued, the drain sequence completes
+ immediately and the encoder returns an empty ``CAPTURE`` buffer with the
+ ``V4L2_BUF_FLAG_LAST`` flag set.
+
+ * In case of no buffer in the ``CAPTURE`` queue at the time the drain
+ sequence completes, the next time the client queues a ``CAPTURE`` buffer
+ it is returned at once as an empty buffer with the ``V4L2_BUF_FLAG_LAST``
+ flag set.
+
+ * If :c:func:`VIDIOC_STREAMOFF` is called on the ``CAPTURE`` queue in the
+ middle of the drain sequence, the drain sequence is canceled and all
+ ``CAPTURE`` buffers are implicitly returned to the client.
+
+ * If :c:func:`VIDIOC_STREAMOFF` is called on the ``OUTPUT`` queue in the
+ middle of the drain sequence, the drain sequence completes immediately and
+ next ``CAPTURE`` buffer will be returned empty with the
+ ``V4L2_BUF_FLAG_LAST`` flag set.
+
+ Although not mandatory, the availability of encoder commands may be queried
+ using :c:func:`VIDIOC_TRY_ENCODER_CMD`.
+
+Reset
+=====
+
+The client may want to request the encoder to reinitialize the encoding, so
+that the following stream data becomes independent from the stream data
+generated before. Depending on the coded format, that may imply that:
+
+* encoded frames produced after the restart must not reference any frames
+ produced before the stop, e.g. no long term references for H.264/HEVC,
+
+* any headers that must be included in a standalone stream must be produced
+ again, e.g. SPS and PPS for H.264/HEVC.
+
+This can be achieved by performing the reset sequence.
+
+1. Perform the `Drain` sequence to ensure all the in-flight encoding finishes
+ and respective buffers are dequeued.
+
+2. Stop streaming on the ``CAPTURE`` queue via :c:func:`VIDIOC_STREAMOFF`. This
+ will return all currently queued ``CAPTURE`` buffers to the client, without
+ valid frame data.
+
+3. Start streaming on the ``CAPTURE`` queue via :c:func:`VIDIOC_STREAMON` and
+ continue with regular encoding sequence. The encoded frames produced into
+ ``CAPTURE`` buffers from now on will contain a standalone stream that can be
+ decoded without the need for frames encoded before the reset sequence,
+ starting at the first ``OUTPUT`` buffer queued after issuing the
+ `V4L2_ENC_CMD_STOP` of the `Drain` sequence.
+
+This sequence may be also used to change encoding parameters for encoders
+without the ability to change the parameters on the fly.
+
+Commit Points
+=============
+
+Setting formats and allocating buffers triggers changes in the behavior of the
+encoder.
+
+1. Setting the format on the ``CAPTURE`` queue may change the set of formats
+ supported/advertised on the ``OUTPUT`` queue. In particular, it also means
+ that the ``OUTPUT`` format may be reset and the client must not rely on the
+ previously set format being preserved.
+
+2. Enumerating formats on the ``OUTPUT`` queue always returns only formats
+ supported for the current ``CAPTURE`` format.
+
+3. Setting the format on the ``OUTPUT`` queue does not change the list of
+ formats available on the ``CAPTURE`` queue. An attempt to set the ``OUTPUT``
+ format that is not supported for the currently selected ``CAPTURE`` format
+ will result in the encoder adjusting the requested ``OUTPUT`` format to a
+ supported one.
+
+4. Enumerating formats on the ``CAPTURE`` queue always returns the full set of
+ supported coded formats, irrespective of the current ``OUTPUT`` format.
+
+5. While buffers are allocated on any of the ``OUTPUT`` or ``CAPTURE`` queues,
+ the client must not change the format on the ``CAPTURE`` queue. Drivers will
+ return the -EBUSY error code for any such format change attempt.
+
+To summarize, setting formats and allocation must always start with the
+``CAPTURE`` queue and the ``CAPTURE`` queue is the master that governs the
+set of supported formats for the ``OUTPUT`` queue.

+Architecture Page Table Helpers
+===============================

+Generic MM expects architectures (with MMU) to provide helpers to create, access
+and modify page table entries at various level for different memory functions.
+These page table helpers need to conform to a common semantics across platforms.
+Following tables describe the expected semantics which can also be tested during
+boot via CONFIG_DEBUG_VM_PGTABLE option. All future changes in here or the debug

+Monitoring Migration
+=====================
+
+The following events (counters) can be used to monitor page migration.
+
+1. PGMIGRATE_SUCCESS: Normal page migration success. Each count means that a
+ page was migrated. If the page was a non-THP page, then this counter is
+ increased by one. If the page was a THP, then this counter is increased by
+ the number of THP subpages. For example, migration of a single 2MB THP that
+ has 4KB-size base pages (subpages) will cause this counter to increase by
+ 512.
+
+2. PGMIGRATE_FAIL: Normal page migration failure. Same counting rules as for
+ _SUCCESS, above: this will be increased by the number of subpages, if it was
+ a THP.
+
+3. THP_MIGRATION_SUCCESS: A THP was migrated without being split.
+
