Introduction
============
Explaining wireless 802.11 networking in the Linux kernel
Copyright 2007-2009 Johannes Berg
These books attempt to give a description of the various subsystems
that play a role in 802.11 wireless networking in Linux. Since these
books are for kernel developers they attempts to document the
structures and functions used in the kernel as well as giving a
higher-level overview.
The reader is expected to be familiar with the 802.11 standard as
published by the IEEE in 802.11-2007 (or possibly later versions).
References to this standard will be given as "802.11-2007 8.1.5".

=============================
mac80211 subsystem (advanced)
=============================
Information contained within this part of the book is of interest only
for advanced interaction of mac80211 with drivers to exploit more
hardware capabilities and improve performance.
LED support
===========
Mac80211 supports various ways of blinking LEDs. Wherever possible,
device LEDs should be exposed as LED class devices and hooked up to the
appropriate trigger, which will then be triggered appropriately by
mac80211.

mac80211 subsystem (basics)
===========================
You should read and understand the information contained within this
part of the book while implementing a mac80211 driver. In some chapters,
advanced usage is noted, those may be skipped if this isn't needed.
This part of the book only covers station and monitor mode
functionality, additional information required to implement the other
modes is covered in the second part of the book.
Basic hardware handling
=======================
TBD
This chapter shall contain information on getting a hw struct allocated
and registered with mac80211.
Since it is required to allocate rates/modes before registering a hw
struct, this chapter shall also contain information on setting up the
rate/mode structs.
Additionally, some discussion about the callbacks and the general
programming model should be in here, including the definition of
ieee80211_ops which will be referred to a lot.
Finally, a discussion of hardware capabilities should be done with
references to other parts of the book.

Virtual interfaces
==================
TBD
This chapter should describe virtual interface basics that are relevant
to the driver (VLANs, MGMT etc are not.) It should explain the use of
the add_iface/remove_iface callbacks as well as the interface
configuration callbacks.
Things related to AP mode should be discussed there.
Things related to supporting multiple interfaces should be in the
appropriate chapter, a BIG FAT note should be here about this though and
the recommendation to allow only a single interface in STA mode at
first!

In ancient (2.4 and earlier) kernels, the nfs server needed to know

information would be given to the kernel by ``mountd`` when the client
mounted the filesystem, or by ``exportfs`` at system startup. exportfs
would take information about active clients from ``/var/lib/nfs/rmtab``.
This approach is quite fragile as it depends on rmtab being correct
which is not always easy, particularly when trying to implement
fail-over. Even when the system is working well, rmtab suffers from
fail-over. Even when the system is working well, ``rmtab`` suffers from
getting lots of old entries that never get removed.
With modern kernels we have the option of having the kernel tell mountd
when it gets a request from an unknown host, and mountd can give
appropriate export information to the kernel. This removes the
dependency on rmtab and means that the kernel only needs to know about
dependency on ``rmtab`` and means that the kernel only needs to know about
currently active clients.

Sphinx
------
The ReST markups currently used by the Documentation/ files are meant to be
built with ``Sphinx`` version 1.2 or upper. If you're desiring to build
PDF outputs, it is recommended to use version 1.4.6.
.. note::
Please notice that, for PDF and LaTeX output, you'll also need ``XeLaTeX``
version 3.14159265. Depending on the distribution, you may also need
to install a series of ``texlive`` packages that provide the minimal
set of functionalities required for ``XeLaTex`` to work.
Other tools
-----------
In order to produce documentation from DocBook, you'll also need ``xmlto``.
Please notice, however, that we're currently migrating all documents to use
``Sphinx``.

DMA_ATTR_NO_WARN
----------------
This tells the DMA-mapping subsystem to suppress allocation failure reports
(similarly to __GFP_NOWARN).
On some architectures allocation failures are reported with error messages
to the system logs. Although this can help to identify and debug problems,
drivers which handle failures (eg, retry later) have no problems with them,
and can actually flood the system logs with error messages that aren't any
problem at all, depending on the implementation of the retry mechanism.
So, this provides a way for drivers to avoid those error messages on calls
where allocation failures are not a problem, and shouldn't bother the logs.
NOTE: At the moment DMA_ATTR_NO_WARN is only implemented on PowerPC.

The dma-buf subsystem provides the framework for sharing buffers
for hardware (DMA) access across multiple device drivers and
subsystems, and for synchronizing asynchronous hardware access.
</para>
<para>
This is used, for example, by drm "prime" multi-GPU support, but
is of course not limited to GPU use cases.
</para>
<para>
The three main components of this are: (1) dma-buf, representing
a sg_table and exposed to userspace as a file descriptor to allow
passing between devices, (2) fence, which provides a mechanism
to signal when one device as finished access, and (3) reservation,
which manages the shared or exclusive fence(s) associated with
the buffer.

<title>Frame Buffer Library</title>
<para>
The frame buffer drivers depend heavily on four data structures.
These structures are declared in include/linux/fb.h. They are
fb_info, fb_var_screeninfo, fb_fix_screeninfo and fb_monospecs.
The last three can be made available to and from userland.
</para>
<para>
fb_info defines the current state of a particular video card.
Inside fb_info, there exists a fb_ops structure which is a
collection of needed functions to make fbdev and fbcon work.
fb_info is only visible to the kernel.
</para>
<para>
fb_var_screeninfo is used to describe the features of a video card
that are user defined. With fb_var_screeninfo, things such as
depth and the resolution may be defined.
</para>
<para>
The next structure is fb_fix_screeninfo. This defines the
properties of a card that are created when a mode is set and can't
be changed otherwise. A good example of this is the start of the
frame buffer memory. This "locks" the address of the frame buffer
memory, so that it cannot be changed or moved.
</para>
<para>
The last structure is fb_monospecs. In the old API, there was
little importance for fb_monospecs. This allowed for forbidden things
such as setting a mode of 800x600 on a fix frequency monitor. With
the new API, fb_monospecs prevents such things, and if used
correctly, can prevent a monitor from being cooked. fb_monospecs
will not be useful until kernels 2.5.x.

<title>Serial Peripheral Interface (SPI)</title>
<para>
SPI is the "Serial Peripheral Interface", widely used with
embedded systems because it is a simple and efficient
interface: basically a multiplexed shift register.
Its three signal wires hold a clock (SCK, often in the range
of 1-20 MHz), a "Master Out, Slave In" (MOSI) data line, and
a "Master In, Slave Out" (MISO) data line.
SPI is a full duplex protocol; for each bit shifted out the
MOSI line (one per clock) another is shifted in on the MISO line.
Those bits are assembled into words of various sizes on the
way to and from system memory.
An additional chipselect line is usually active-low (nCS);
four signals are normally used for each peripheral, plus
sometimes an interrupt.
</para>
<para>
The SPI bus facilities listed here provide a generalized
interface to declare SPI busses and devices, manage them
according to the standard Linux driver model, and perform
input/output operations.
At this time, only "master" side interfaces are supported,
where Linux talks to SPI peripherals and does not implement
such a peripheral itself.
(Interfaces to support implementing SPI slaves would
necessarily look different.)
</para>
<para>
The programming interface is structured around two kinds of driver,
and two kinds of device.
A "Controller Driver" abstracts the controller hardware, which may
be as simple as a set of GPIO pins or as complex as a pair of FIFOs
connected to dual DMA engines on the other side of the SPI shift
register (maximizing throughput). Such drivers bridge between
whatever bus they sit on (often the platform bus) and SPI, and
expose the SPI side of their device as a
<structname>struct spi_master</structname>.
SPI devices are children of that master, represented as a
<structname>struct spi_device</structname> and manufactured from
<structname>struct spi_board_info</structname> descriptors which
are usually provided by board-specific initialization code.
A <structname>struct spi_driver</structname> is called a
"Protocol Driver", and is bound to a spi_device using normal
driver model calls.
</para>
<para>
The I/O model is a set of queued messages. Protocol drivers
submit one or more <structname>struct spi_message</structname>
objects, which are processed and completed asynchronously.
(There are synchronous wrappers, however.) Messages are
built from one or more <structname>struct spi_transfer</structname>
objects, each of which wraps a full duplex SPI transfer.
A variety of protocol tweaking options are needed, because
different chips adopt very different policies for how they
use the bits transferred with SPI.

<chapter id="i2c">
<title>I<superscript>2</superscript>C and SMBus Subsystem</title>
<para>
I<superscript>2</superscript>C (or without fancy typography, "I2C")
is an acronym for the "Inter-IC" bus, a simple bus protocol which is
widely used where low data rate communications suffice.
Since it's also a licensed trademark, some vendors use another
name (such as "Two-Wire Interface", TWI) for the same bus.
I2C only needs two signals (SCL for clock, SDA for data), conserving
board real estate and minimizing signal quality issues.
Most I2C devices use seven bit addresses, and bus speeds of up
to 400 kHz; there's a high speed extension (3.4 MHz) that's not yet
found wide use.
I2C is a multi-master bus; open drain signaling is used to
arbitrate between masters, as well as to handshake and to
synchronize clocks from slower clients.
</para>
<para>
The Linux I2C programming interfaces support only the master
side of bus interactions, not the slave side.
The programming interface is structured around two kinds of driver,
and two kinds of device.
An I2C "Adapter Driver" abstracts the controller hardware; it binds
to a physical device (perhaps a PCI device or platform_device) and
exposes a <structname>struct i2c_adapter</structname> representing
each I2C bus segment it manages.
On each I2C bus segment will be I2C devices represented by a
<structname>struct i2c_client</structname>. Those devices will
be bound to a <structname>struct i2c_driver</structname>,
which should follow the standard Linux driver model.
(At this writing, a legacy model is more widely used.)
There are functions to perform various I2C protocol operations; at
this writing all such functions are usable only from task context.
</para>
<para>
The System Management Bus (SMBus) is a sibling protocol. Most SMBus
systems are also I2C conformant. The electrical constraints are
tighter for SMBus, and it standardizes particular protocol messages
and idioms. Controllers that support I2C can also support most
SMBus operations, but SMBus controllers don't support all the protocol
options that an I2C controller will.
There are functions to perform various SMBus protocol operations,
either using I2C primitives or by issuing SMBus commands to
i2c_adapter devices which don't support those I2C operations.

<chapter id="pwm">
<title>Pulse-Width Modulation (PWM)</title>
<para>
Pulse-width modulation is a modulation technique primarily used to
control power supplied to electrical devices.
</para>
<para>
The PWM framework provides an abstraction for providers and consumers
of PWM signals. A controller that provides one or more PWM signals is
registered as <structname>struct pwm_chip</structname>. Providers are
expected to embed this structure in a driver-specific structure. This
structure contains fields that describe a particular chip.
</para>
<para>
A chip exposes one or more PWM signal sources, each of which exposed
as a <structname>struct pwm_device</structname>. Operations can be
performed on PWM devices to control the period, duty cycle, polarity
and active state of the signal.
</para>
<para>
Note that PWM devices are exclusive resources: they can always only be
used by one consumer at a time.
