+<title>Introduction</title>
+
+<para>The LIRC device interface is a bi-directional interface for
+transporting raw IR data between userspace and kernelspace. Fundamentally,
+it is just a chardev (/dev/lircX, for X = 0, 1, 2, ...), with a number
+of standard struct file_operations defined on it. With respect to
+transporting raw IR data to and fro, the essential fops are read, write
+and ioctl.</para>
+
+<para>Example dmesg output upon a driver registering w/LIRC:</para>
+ <blockquote>
+ <para>$ dmesg |grep lirc_dev</para>
+ <para>lirc_dev: IR Remote Control driver registered, major 248</para>
+ <para>rc rc0: lirc_dev: driver ir-lirc-codec (mceusb) registered at minor = 0</para>
+ </blockquote>
+
+<para>What you should see for a chardev:</para>
+ <blockquote>
+ <para>$ ls -l /dev/lirc*</para>
+ <para>crw-rw---- 1 root root 248, 0 Jul 2 22:20 /dev/lirc0</para>
+ </blockquote>
+</section>
+
+<section id="lirc_read">
+<title>LIRC read fop</title>
+
+<para>The lircd userspace daemon reads raw IR data from the LIRC chardev. The
+exact format of the data depends on what modes a driver supports, and what
+mode has been selected. lircd obtains supported modes and sets the active mode
+via the ioctl interface, detailed at <xref linkend="lirc_ioctl"/>. The generally
+preferred mode is LIRC_MODE_MODE2, in which packets containing an int value
+describing an IR signal are read from the chardev.</para>
+
+<para>See also <ulink url="http://www.lirc.org/html/technical.html">http://www.lirc.org/html/technical.html</ulink> for more info.</para>
+</section>
+
+<section id="lirc_write">
+<title>LIRC write fop</title>
+
+<para>The data written to the chardev is a pulse/space sequence of integer
+values. Pulses and spaces are only marked implicitly by their position. The
+data must start and end with a pulse, therefore, the data must always include
+an unevent number of samples. The write function must block until the data has
+been transmitted by the hardware.</para>
+</section>
+
+<section id="lirc_ioctl">
+<title>LIRC ioctl fop</title>
+
+<para>The LIRC device's ioctl definition is bound by the ioctl function
+definition of struct file_operations, leaving us with an unsigned int
+for the ioctl command and an unsigned long for the arg. For the purposes
+of ioctl portability across 32-bit and 64-bit, these values are capped
+to their 32-bit sizes.</para>
+
+<para>The following ioctls can be used to change specific hardware settings.
+In general each driver should have a default set of settings. The driver
+implementation is expected to re-apply the default settings when the device
+is closed by user-space, so that every application opening the device can rely
+on working with the default settings initially.</para>
+
+<variablelist>
+ <varlistentry>
+ <term>LIRC_GET_FEATURES</term>
+ <listitem>
+ <para>Obviously, get the underlying hardware device's features. If a driver
+ does not announce support of certain features, calling of the corresponding
+ ioctls is undefined.</para>
+ </listitem>

+ <varlistentry>
+ <term>LIRC_{G,S}ET_{SEND,REC}_DUTY_CYCLE</term>
+ <listitem>
+ <para>Get/set the duty cycle (from 0 to 100) of the carrier signal. Currently,
+ no special meaning is defined for 0 or 100, but this could be used to switch
+ off carrier generation in the future, so these values should be reserved.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_GET_REC_RESOLUTION</term>
+ <listitem>
+ <para>Some receiver have maximum resolution which is defined by internal
+ sample rate or data format limitations. E.g. it's common that signals can
+ only be reported in 50 microsecond steps. This integer value is used by
+ lircd to automatically adjust the aeps tolerance value in the lircd
+ config file.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_GET_M{IN,AX}_TIMEOUT</term>
+ <listitem>
+ <para>Some devices have internal timers that can be used to detect when
+ there's no IR activity for a long time. This can help lircd in detecting
+ that a IR signal is finished and can speed up the decoding process.
+ Returns an integer value with the minimum/maximum timeout that can be
+ set. Some devices have a fixed timeout, in that case both ioctls will
+ return the same value even though the timeout cannot be changed.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_GET_M{IN,AX}_FILTER_{PULSE,SPACE}</term>
+ <listitem>
+ <para>Some devices are able to filter out spikes in the incoming signal
+ using given filter rules. These ioctls return the hardware capabilities
+ that describe the bounds of the possible filters. Filter settings depend
+ on the IR protocols that are expected. lircd derives the settings from
+ all protocols definitions found in its config file.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_GET_LENGTH</term>
+ <listitem>
+ <para>Retrieves the code length in bits (only for LIRC_MODE_LIRCCODE).

+ <listitem>

+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_SET_TRANSMITTER_MASK</term>
+ <listitem>
+ <para>This enables the given set of transmitters. The first transmitter
+ is encoded by the least significant bit, etc. When an invalid bit mask
+ is given, i.e. a bit is set, even though the device does not have so many
+ transitters, then this ioctl returns the number of available transitters
+ and does nothing otherwise.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_SET_REC_TIMEOUT</term>
+ <listitem>
+ <para>Sets the integer value for IR inactivity timeout (cf.
+ LIRC_GET_MIN_TIMEOUT and LIRC_GET_MAX_TIMEOUT). A value of 0 (if
+ supported by the hardware) disables all hardware timeouts and data should
+ be reported as soon as possible. If the exact value cannot be set, then
+ the next possible value _greater_ than the given value should be set.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_SET_REC_TIMEOUT_REPORTS</term>
+ <listitem>
+ <para>Enable (1) or disable (0) timeout reports in LIRC_MODE_MODE2. By
+ default, timeout reports should be turned off.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_SET_REC_FILTER_{,PULSE,SPACE}</term>
+ <listitem>
+ <para>Pulses/spaces shorter than this are filtered out by hardware. If
+ filters cannot be set independently for pulse/space, the corresponding
+ ioctls must return an error and LIRC_SET_REC_FILTER shall be used instead.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_SET_MEASURE_CARRIER_MODE</term>
+ <listitem>
+ <para>Enable (1)/disable (0) measure mode. If enabled, from the next key
+ press on, the driver will send LIRC_MODE2_FREQUENCY packets. By default
+ this should be turned off.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_SET_REC_{DUTY_CYCLE,CARRIER}_RANGE</term>
+ <listitem>
+ <para>To set a range use LIRC_SET_REC_DUTY_CYCLE_RANGE/LIRC_SET_REC_CARRIER_RANGE
+ with the lower bound first and later LIRC_SET_REC_DUTY_CYCLE/LIRC_SET_REC_CARRIER
+ with the upper bound.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_NOTIFY_DECODE</term>
+ <listitem>
+ <para>This ioctl is called by lircd whenever a successful decoding of an
+ incoming IR signal could be done. This can be used by supporting hardware
+ to give visual feedback to the user e.g. by flashing a LED.</para>
+ </listitem>
+ </varlistentry>
+ <varlistentry>
+ <term>LIRC_SETUP_{START,END}</term>
+ <listitem>
+ <para>Setting of several driver parameters can be optimized by encapsulating
+ the according ioctl calls with LIRC_SETUP_START/LIRC_SETUP_END. When a
+ driver receives a LIRC_SETUP_START ioctl it can choose to not commit
+ further setting changes to the hardware until a LIRC_SETUP_END is received.
+ But this is open to the driver implementation and every driver must also
+ handle parameter changes which are not encapsulated by LIRC_SETUP_START
+ and LIRC_SETUP_END. Drivers can also choose to ignore these ioctls.</para>

+ * Driver for USB Windows Media Center Ed. eHome Infrared Transceivers
+ *
+ * Copyright (c) 2010 by Jarod Wilson <jarod@redhat.com>
+ *
+ * Based on the original lirc_mceusb and lirc_mceusb2 drivers, by Dan
+ * Conti, Martin Blatter and Daniel Melander, the latter of which was
+ * in turn also based on the lirc_atiusb driver by Paul Miller. The
+ * two mce drivers were merged into one by Jarod Wilson, with transmit
+ * support for the 1st-gen device added primarily by Patrick Calhoun,
+ * with a bit of tweaks by Jarod. Debugging improvements and proper
+ * support for what appears to be 3rd-gen hardware added by Jarod.
+ * Initial port from lirc driver to ir-core drivery by Jarod, based
+ * partially on a port to an earlier proposed IR infrastructure by
+ * Jon Smirl, which included enhancements and simplifications to the
+ * incoming IR buffer parsing routines.
