+<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>

- * If an unknown protocol name is used, returns -EINVAL.
+ * It is trigged by writing to /sys/class/rc/rc?/protocols.
+ * Writing "+proto" will add a protocol to the list of enabled protocols.

+ * 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.

- *
- * Thanks to STMicroelectronics for information on the usb commands, and
- * to Steve Miller at STM for his help and encouragement while I was
- * writing this driver.
- *
- * This driver is based heavily on the
- * Endpoints (formerly known as AOX) se401 USB Camera Driver
- * Copyright (c) 2000 Jeroen B. Vreeken (pe1rxq@amsat.org)
- *
- * Still somewhat based on the Linux ov511 driver.

- * along with this program; if not, write to the Free Software Foundation,
- * Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- * History:
- * ver 0.1 October, 2001. Initial attempt.
- *
- * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
- *                         function, made more stable (?)
- *
- * ver 0.21 Nov, 2001.     Added gamma correction and white balance,
- *                         due to Alexander Schwartz. Still trying to
- *                         improve stablility. Moved stuff into stv680.h
- *
- * ver 0.22 Nov, 2001.     Added sharpen function (by Michael Sweet,
- *                         mike@easysw.com) from GIMP, also used in pencam.
- *                         Simple, fast, good integer math routine.
- *
- * ver 0.23 Dec, 2001 (gkh)
- *                         Took out sharpen function, ran code through
- *                         Lindent, and did other minor tweaks to get
- *                         things to work properly with 2.5.1
- *
- * ver 0.24 Jan, 2002 (kjs)
- *                         Fixed the problem with webcam crashing after
- *                         two pictures. Changed the way pic is halved to
- *                         improve quality. Got rid of green line around
- *                         frame. Fix brightness reset when changing size
- *                         bug. Adjusted gamma filters slightly.
- *
- * ver 0.25 Jan, 2002 (kjs)
- *                         Fixed a bug in which the driver sometimes attempted
- *                         to set to a non-supported size. This allowed
- *                         gnomemeeting to work.
- *                         Fixed proc entry removal bug.

- * This is a shameless copy from the USB-cpia driver (linux kernel

- * Actually it seems to be a copy of a shameless copy of the bttv-driver.
- * Or that is a copy of a shameless copy of ... (To the powers: is there
- * no generic kernel-function to do this sort of stuff?)
- *
- * Yes, it was a shameless copy from the bttv-driver. IIRC, Alan says
- * there will be one, but apparentely not yet -jerdfelt
- *
- * So I copied it again for the ov511 driver -claudio

- * Same for the se401 driver -Jeroen

- * And the STV0680 driver - Kevin

+ * lirc_igorplugusb - USB remote support for LIRC
+ *
+ * Supports the standard homebrew IgorPlugUSB receiver with Igor's firmware.
+ * See http://www.cesko.host.sk/IgorPlugUSB/IgorPlug-USB%20(AVR)_eng.htm
+ *
+ * The device can only record bursts of up to 36 pulses/spaces.
+ * Works fine with RC5. Longer commands lead to device buffer overrun.
+ * (Maybe a better firmware or a microcontroller with more ram can help?)
+ *
+ * Version 0.1  [beta status]
+ *
+ * Copyright (C) 2004 Jan M. Hochstein
+ *      <hochstein@algo.informatik.tu-darmstadt.de>
+ *
+ * This driver was derived from:
+ *   Paul Miller <pmiller9@users.sourceforge.net>
+ *      "lirc_atiusb" module
+ *   Vladimir Dergachev <volodya@minspring.com>'s 2002

+ * The ITE8709 device seems to be the combination of IT8512 superIO chip and

+ * In addition of the embedded micro-controller, the IT8512 chip contains a
+ * CIR module and several other modules. A few modules are directly accessible
+ * by the host CPU, but most of them are only accessible by the
+ * micro-controller. The CIR module is only accessible by the micro-controller.
+ * The battery-backed SRAM module is accessible by the host CPU and the
+ * micro-controller. So one of the MC's firmware role is to act as a bridge
+ * between the host CPU and the CIR module. The firmware implements a kind of
+ * communication protocol using the SRAM module as a shared memory. The IT8512
+ * specification is publicly available on ITE's web site, but the communication
+ * protocol is not, so it was reverse-engineered.

+ * Steve's changes to improve transmission fidelity:
+ *   - for systems with the rdtsc instruction and the clock counter, a
+ *     send_pule that times the pulses directly using the counter.
+ *     This means that the LIRC_SERIAL_TRANSMITTER_LATENCY fudge is
+ *     not needed. Measurement shows very stable waveform, even where
+ *     PCI activity slows the access to the UART, which trips up other
+ *     versions.
+ *   - For other system, non-integer-microsecond pulse/space lengths,
+ *     done using fixed point binary. So, much more accurate carrier
+ *     frequency.
+ *   - fine tuned transmitter latency, taking advantage of fractional
+ *     microseconds in previous change
+ *   - Fixed bug in the way transmitter latency was accounted for by
+ *     tuning the pulse lengths down - the send_pulse routine ignored
+ *     this overhead as it timed the overall pulse length - so the
+ *     pulse frequency was right but overall pulse length was too
+ *     long. Fixed by accounting for latency on each pulse/space
+ *     iteration.

+ * Streamzap Remote Control driver
+ *
+ * Copyright (c) 2005 Christoph Bartelmus <lirc@bartelmus.de>
+ *
+ * This driver was based on the work of Greg Wickham and Adrian
+ * Dewhurst. It was substantially rewritten to support correct signal
+ * gaps and now maintains a delay buffer, which is used to present
+ * consistent timing behaviour to user space applications. Without the
+ * delay buffer an ugly hack would be required in lircd, which can
+ * cause sluggish signal decoding in certain situations.
+ *
+ * This driver is based on the USB skeleton driver packaged with the
+ * kernel; copyright (C) 2001-2003 Greg Kroah-Hartman (greg@kroah.com)

+ *   set_use_inc/set_use_dec are not being executed and will not be
+ *   called after lirc_unregister_driver returns.
+ *
+ * - by the timer callback
+ *
+ *   The timer is only running when the device is connected and the
+ *   LIRC device is open. Making sure the timer is deleted by
+ *   set_use_dec will make conflicts impossible.

+ * Currently the driver reduces the sampling rate by factor of 8 as this

+ * But the driver does not rely on RC-5 it should be able to decode every
+ * IR signal that is not too fast.
