+                Defines the interval in milliseconds in which batman
+                sends its protocol messages.
+
+What:           /sys/class/net/<mesh_iface>/mesh/vis_mode
+Date:           May 2010
+Contact:        Marek Lindner <lindner_marek@yahoo.de>
+Description:
+                Each batman node only maintains information about its
+                own local neighborhood, therefore generating graphs
+                showing the topology of the entire mesh is not easily
+                feasible without having a central instance to collect
+                the local topologies from all nodes. This file allows
+                to activate the collecting (server) mode.

- *   works - driver works correctly on most boards supported, and
- *     passes comedi_test.
- *   unknown - unknown.  Usually put there by ds.
- *   experimental - may not work in any particular release.  Author
- *     probably wants assistance testing it.
- *   bitrotten - driver has not been update in a long time, probably
- *     doesn't work, and probably is missing support for significant
- *     Comedi interface features.
- *   untested - author probably wrote it "blind", and is believed to
- *     work, but no confirmation.
- *
- * These headers should be followed by a blank line, and any comments
- * you wish to say about the driver.  The comment area is the place
- * to put any known bugs, limitations, unsupported features, supported
- * command triggers, whether or not commands are supported on particular
- * subdevices, etc.
- *
- * Somewhere in the comment should be information about configuration
- * options that are used with comedi_config.

-Updated: Mon, 06 Aug 2007 12:03:15 +0100
-Status: works (I hope. My board fire up under my hands
-               and I cann't test all features.)
-
-This driver supports insn and cmd interfaces. Some boards support only insn
-becouse their hardware don't allow more (PCL-813/B, ACL-8113, ISO-813).
-Data transfer over DMA is supported only when you measure only one
-channel, this is too hardware limitation of these boards.

+ * Status: works (I hope. My board fire up under my hands
+ *	       and I cann't test all features.)
+ *
+ * This driver supports insn and cmd interfaces. Some boards support only insn
+ * becouse their hardware don't allow more (PCL-813/B, ACL-8113, ISO-813).
+ * Data transfer over DMA is supported only when you measure only one
+ * channel, this is too hardware limitation of these boards.

+
+SUPPORTED HARDWARE
+------------------
+
+This driver is intended for use with hardware having USB ID 05e1:0408.
+Two kinds of EasyCAP have this USB ID, namely:
+
+    *  EasyCAP USB 2.0 Video Adapter with Audio, Model DC60,
+       having input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
+
+    *  EasyCAP002 4-Channel USB 2.0 DVR, having input cables labelled
+       1, 2, 3, 4 and an unlabelled input cable for a microphone.
+
+
+BUILD OPTIONS AND DEPENDENCIES
+------------------------------
+
+If the parameter EASYCAP_IS_VIDEODEV_CLIENT is undefined during compilation
+the built module is entirely independent of the videodev module, and when
+the EasyCAP is physically plugged into a USB port the special files
+/dev/easycap0 and /dev/easysnd1 are created as video and sound sources
+respectively.
+
+If the parameter EASYCAP_IS_VIDEODEV_CLIENT is defined during compilation
+the built easycap module is configured to register with the videodev module,
+in which case the special files created when the EasyCAP is plugged in are
+/dev/video0 and /dev/easysnd0.  Use of the easycap module as a client of
+the videodev module has received very little testing as of June 2010.
+
+
+KNOWN BUILD PROBLEMS
+--------------------
+
+(1) Recent gcc versions may generate the message:
+
+     warning: the frame size of .... bytes is larger than 1024 bytes
+
+This warning can be suppressed by specifying in the Makefile:
+
+     EXTRA_CFLAGS += -Wframe-larger-than=8192
+
+but it would be preferable to remove the cause of the warning.
+
+
+KNOWN RUNTIME ISSUES
+--------------------
+
+(1) Randomly (maybe 5 to 10% of occasions) the driver fails to produce any
+output at start-up.  Closing mplayer (or whatever the user program is) and
+restarting it restores normal performance without any other remedial action
+being necessary.  The reason for this is not known.
+
+(2) Intentionally, this driver will not stream material which is unambiguously
+identified by the hardware as copy-protected.  The video output will freeze
+within about a minute when this situation arises.
+
+(3) The controls for luminance, contrast, saturation, hue and volume may not
+always work properly.
+
+(4) Reduced-resolution S-Video seems to suffer from moire artefacts.  No
+attempt has yet been made to rememdy this.
+
+
+SUPPORTED TV STANDARDS AND RESOLUTIONS
+--------------------------------------
+
+The following TV standards are natively supported by the hardware and are
+usable as (for example) the "norm=" parameter in the mplayer command:
+
+    PAL_BGHIN,    NTSC_N_443,
+    PAL_Nc,       NTSC_N,
+    SECAM,        NTSC_M,        NTSC_M_JP,
+    PAL_60,       NTSC_443,
+    PAL_M.
+
+The available picture sizes are:
+
+     at 25 frames per second:   720x576, 704x576, 640x480, 360x288, 320x240;
+     at 30 frames per second:   720x480, 640x480, 360x240, 320x240;
+
+
+WHAT'S TESTED AND WHAT'S NOT
+----------------------------
+
+This driver is known to work with mplayer, mencoder, tvtime and sufficiently
+recent versions of vlc.  An interface to ffmpeg is implemented, but serious
+audio-video synchronization problems remain.
+
+The driver is designed to support all the TV standards accepted by the
+hardware, but as yet it has actually been tested on only a few of these.
+
+I have been unable to test and calibrate the S-video input myself because I
+do not possess any equipment with S-video output.
+
+This driver does not understand the V4L1 IOCTL commands, so programs such
+as camorama are not compatible.  There are reports that the driver does
+work with sufficiently recent (V4L2) versions of zoneminder, but I have not
+attempted to confirm this myself.
+
+
+UDEV RULES
+----------
+
+In order that the special files /dev/easycap0 and /dev/easysnd1 are created
+with conveniently relaxed permissions when the EasyCAP is plugged in, a file
+is preferably to be provided in directory /etc/udev/rules.d with content:
+
+ACTION!="add|change", GOTO="easycap_rules_end"
+ATTRS{idVendor}=="05e1", ATTRS{idProduct}=="0408", \
+	MODE="0666", OWNER="root", GROUP="root"
+LABEL="easycap_rules_end"
+
+
+ACKNOWLEGEMENTS AND REFERENCES
+------------------------------
+This driver makes use of information contained in the Syntek Semicon DC-1125
+Driver, presently maintained at http://sourceforge.net/projects/syntekdriver/
+by Nicolas Vivien.  Particularly useful has been a patch to the latter driver
+provided by Ivor Hewitt in January 2009.  The NTSC implementation is taken
+from the work of Ben Trask.

-
-TODO:
-	- checkpatch.pl cleanups
-	- sparse cleanups
-	- port to in-kernel 80211 stack

+This driver is unmaintained and its only purpose is as a
+source of documentation for developers working on ar9170 and carl9170.
+Once carl9170 gets 11n support and merged upstream then this driver

-ramzswap: Compressed RAM based swap device
--------------------------------------------
-
-Project home: http://compcache.googlecode.com/
-
-* Introduction
-
-The ramzswap module creates RAM based block devices which can (only) be used as
-swap disks. Pages swapped to these devices are compressed and stored in memory
-itself. See project home for use cases, performance numbers and a lot more.
-
-Individual ramzswap devices are configured and initialized using rzscontrol
-userspace utility as shown in examples below. See rzscontrol man page for more
-details.
-
-* Usage
-
-Following shows a typical sequence of steps for using ramzswap.
-
-1) Load Modules:
-	modprobe ramzswap num_devices=4
-	This creates 4 (uninitialized) devices: /dev/ramzswap{0,1,2,3}
-	(num_devices parameter is optional. Default: 1)
-
-2) Initialize:
-	Use rzscontrol utility to configure and initialize individual
-	ramzswap devices. Example:
-	rzscontrol /dev/ramzswap2 --init # uses default value of disksize_kb
-
-	*See rzscontrol man page for more details and examples*
-
-3) Activate:
-	swapon /dev/ramzswap2 # or any other initialized ramzswap device
-
-4) Stats:
-	rzscontrol /dev/ramzswap2 --stats
-
-5) Deactivate:
-	swapoff /dev/ramzswap2
-
-6) Reset:
-	rzscontrol /dev/ramzswap2 --reset
-	(This frees all the memory allocated for this device).
-

+This is a driver for NAND controller of Intel Moorestown platform.
+
+This driver is a standalone linux block device driver, it acts as if it's a normal hard disk.
+It includes three layer:
+	block layer interface - file ffsport.c
+	Flash Translation Layer (FTL) - file flash.c (implement the NAND flash Translation Layer, includs address mapping, garbage collection, wear-leveling and so on)
+	Low level layer - file lld_nand.c/lld_cdma.c/lld_emu.c (which implements actual controller hardware registers access)
+
+This driver can be build as modules or build-in.
+
+Dependency:
+This driver has dependency on IA Firmware of Intel Moorestown platform.
+It need the IA Firmware to create the block table for the first time.
+And to validate this driver code without IA Firmware, you can change the
+macro AUTO_FORMAT_FLASH from 0 to 1 in file spectraswconfig.h. Thus the
+driver will erase the whole nand flash and create a new block table.
+
+TODO:
+	- Enable Command DMA feature support
+	- lower the memory footprint
+	- Remove most of the unnecessary global variables
+	- Change all the upcase variable / functions name to lowercase
+	- Some other misc bugs
+
+Please send patches to:
+	Greg Kroah-Hartman <gregkh@suse.de>

+*               block table in place, then use it to scan for bad blocks
+*               If not, then scan for MDF.
+*               Now, a block table will only be found if spectra was already
+*               being used. For a fresh flash, we'll go thru scanning for
+*               MDF. If spectra was being used, then there is a chance that
+*               the MDF has been corrupted. Spectra avoids writing to the
+*               first 2 bytes of the spare area to all pages in a block. This
+*               covers all known flash devices. However, since flash
+*               manufacturers have no standard of where the MDF is stored,
+*               this cannot guarantee that the MDF is protected for future
+*               devices too. The initial scanning for the block table assures

+*               we're looking for are bad block markers.

 1. A per-device/tty port context required to support multiple devices
 on same platform.
+Plan: Each BT, FM and GPS device would be a platform-device with its platform-data
+mentioning which of the ST device it wants to attach itself onto.
 
-2. REMOVE the sysfs entry PID passing mechanism, since there should
-be a better way to request user-space to install line discipline.
+There by each of the ST device which is also a platform device upon receiving
+a st_register() would know whether the registration from BT/FM or GPS was intended for it.

+2. Improve upon the way requirement of line discipline is communicated to
+user-space, The current user-space application which open/installs ldisc
+as and when required can be found at,

+
+DSP/BIOS Bridge overview
+========================
+
+DSP/BIOS Bridge is designed for platforms that contain a GPP and one or more
+attached DSPs.  The GPP is considered the master or "host" processor, and the
+attached DSPs are processing resources that can be utilized by applications
+and drivers running on the GPP.
+
+The abstraction that DSP/BIOS Bridge supplies, is a direct link between a GPP
+program and a DSP task.  This communication link is partitioned into two
+types of sub-links:  messaging (short, fixed-length packets) and data
+streaming (multiple, large buffers).  Each sub-link operates independently,
+and features in-order delivery of data, meaning that messages are delivered
+in the order they were submitted to the message link, and stream buffers are
+delivered in the order they were submitted to the stream link.
+
+In addition, a GPP client can specify what inputs and outputs a DSP task
+uses. DSP tasks typically use message objects for passing control and status
+information and stream objects for efficient streaming of real-time data.
+
+GPP Software Architecture
+=========================
+
+A GPP application communicates with its associated DSP task running on the
+DSP subsystem using the DSP/BIOS Bridge API. For example, a GPP audio
+application can use the API to pass messages to a DSP task that is managing
+data flowing from analog-to-digital converters (ADCs) to digital-to-analog
+converters (DACs).
+
+From the perspective of the GPP OS, the DSP is treated as just another
+peripheral device.   Most high level GPP OS typically support a device driver
+model, whereby applications can safely access and share a hardware peripheral
+through standard driver interfaces.  Therefore, to allow multiple GPP
+applications to share access to the DSP, the GPP side of DSP/BIOS Bridge
+implements a device driver for the DSP.
+
+Since driver interfaces are not always standard across GPP OS, and to provide
+some level of interoperability of application code using DSP/BIOS Bridge
+between GPP OS, DSP/BIOS Bridge provides a standard library of APIs which
+wrap calls into the device driver.   So, rather than calling GPP OS specific
+driver interfaces, applications (and even other device drivers) can use the
+standard API library directly.
+
+DSP Software Architecture
+=========================
+
+For DSP/BIOS, DSP/BIOS Bridge adds a device-independent streaming I/O (STRM)
+interface, a messaging interface (NODE), and a Resource Manager (RM) Server.
+The RM Server runs as a task of DSP/BIOS and is subservient to commands
+and queries from the GPP.  It executes commands to start and stop DSP signal
+processing nodes in response to GPP programs making requests through the
+(GPP-side) API.
+
+DSP tasks started by the RM Server are similar to any other DSP task with two
+important differences:  they must follow a specific task model consisting of
+three C-callable functions (node create, execute, and delete), with specific
+sets of arguments, and they have a pre-defined task environment established
+by the RM Server.
+
+Tasks started by the RM Server communicate using the STRM and NODE interfaces
+and act as servers for their corresponding GPP clients, performing signal
+processing functions as requested by messages sent by their GPP client.
+Typically, a DSP task moves data from source devices to sink devices using
+device independent I/O streams, performing application-specific processing
+and transformations on the data while it is moved.  For example, an audio
+task might perform audio decompression (ADPCM, MPEG, CELP) on data received
+from a GPP audio driver and then send the decompressed linear samples to a
+digital-to-analog converter.

+			DSP/Bridge Error Code Guide
+
+
+Success code is always taken as 0, except for one case where a success status
+different than 0 can be possible, this is when enumerating a series of dsp
+objects, if the enumeration doesn't have any more objects it is considered as a
+successful case. In this case a positive ENODATA is returned (TODO: Change to
+avoid this case).
+
+Error codes are returned as a negative 1, if an specific code is expected, it
+can be propagated to user space by reading errno symbol defined in errno.h, for
+specific details on the implementation a copy of the standard used should be
+read first.
+
+The error codes used by this driver are:
+
+[EPERM]
+    General driver failure.
+
+    According to the use case the following might apply:
+    - Device is in 'sleep/suspend' mode due to DPM.
+    - User cannot mark end of stream on an input channel.
+    - Requested operation is invalid for the node type.
+    - Invalid alignment for the node messaging buffer.
+    - The specified direction is invalid for the stream.
+    - Invalid stream mode.
+
+[ENOENT]
+    The specified object or file was not found.
+
+[ESRCH]
+    A shared memory buffer contained in a message or stream could not be mapped
+    to the GPP client process's virtual space.
+
+[EIO]
+    Driver interface I/O error.
+
+    or:
+    - Unable to plug channel ISR for configured IRQ.
+    - No free I/O request packets are available.
+
+[ENXIO]
+    Unable to find a named section in DSP executable or a non-existent memory
+    segment identifier was specified.
+
+[EBADF]
+    General error for file handling:
+
+    - Unable to open file.
+    - Unable to read file.
+    - An error occurred while parsing the DSP executable file.
+
+[ENOMEM]
+    A memory allocation failure occurred.
+
+[EACCES]
+    - Unable to read content of DCD data section; this is typically caused by
+    improperly configured nodes.
+    - Unable to decode DCD data section content; this is typically caused by
+    changes to DSP/BIOS Bridge data structures.
+    - Unable to get pointer to DCD data section; this is typically caused by
+    improperly configured UUIDs.
+    - Unable to load file containing DCD data section; this is typically
+    caused by a missing COFF file.
+    - The specified COFF file does not contain a valid node registration
+    section.
+
+[EFAULT]
+    Invalid pointer or handler.
+
+[EEXIST]
+    Attempted to create a channel manager  when one already exists.
+
+[EINVAL]
+    Invalid argument.
+
+[ESPIPE]
+    Symbol not found in the COFF file.  DSPNode_Create will return this if
+    the iAlg function table for an xDAIS socket is not found in the COFF file.
+    In this case, force the symbol to be linked into the COFF file.
+    DSPNode_Create, DSPNode_Execute, and DSPNode_Delete will return this if
+    the create, execute, or delete phase function, respectively, could not be
+    found in the COFF file.
+
+    - No symbol table is loaded/found for this board.
+    - Unable to initialize the ZL COFF parsing module.
+
+[EPIPE]

+    A parameter is specified outside its valid range.
+
+[ENOSYS]
+    The indicated operation is not supported.
+
+[EIDRM]
+    During enumeration a change in the number or properties of the objects
+    has occurred.
+
+[ECHRNG]
+    Attempt to created channel manager with too many channels or channel ID out
+    of range.
+
+[EBADR]
+    The state of the specified object is incorrect for the requested operation.
+
+    - Invalid segment ID.
+
+[ENODATA]
+    Unable to retrieve resource information from the registry.
+
+    - No more registry values.
+

+ * This C header file gives the layout of the data structure created by the
+ * dynamic loader to describe the set of modules loaded into the DSP.
+ *
+ * Linked List Structure:
+ * ----------------------
+ * The data structure defined here is a singly-linked list.  The list
+ * represents the set of modules which are currently loaded in the DSP memory.
+ * The first entry in the list is a header record which contains a flag
+ * representing the state of the list.  The rest of the entries in the list
+ * are module records.
+ *
+ * Global symbol  _DLModules designates the first record in the list (i.e. the
+ * header record).  This symbol must be defined in any program that wishes to
+ * use DLLview plug-in.
+ *
+ * String Representation:
+ * ----------------------
+ * The string names of the module and its sections are stored in a block of
+ * memory which follows the module record itself.  The strings are ordered:
+ * module name first, followed by section names in order from the first
+ * section to the last.  String names are tightly packed arrays of 8-bit
+ * characters (two characters per 16-bit word on the C55x).  Strings are
+ * zero-byte-terminated.
+ *
+ * Creating and updating the list:
+ * -------------------------------
+ * Upon loading a new module into the DSP memory the dynamic loader inserts a
+ * new module record as the first module record in the list.  The fields of
+ * this module record are initialized to reflect the properties of the module.
+ * The dynamic loader does NOT increment the flag/counter in the list's header
+ * record.
+ *
+ * Upon unloading a module from the DSP memory the dynamic loader removes the
+ * module's record from this list.  The dynamic loader also increments the
+ * flag/counter in the list's header record to indicate that the list has been
+ * changed.

+zram: Compressed RAM based block devices
+----------------------------------------
+
+Project home: http://compcache.googlecode.com/
+
+* Introduction
+
+The zram module creates RAM based block devices: /dev/ramX (X = 0, 1, ...).
+Pages written to these disks are compressed and stored in memory itself.
+These disks allow very fast I/O and compression provides good amounts of
+memory savings.
+
+See project home for use cases, performance numbers and a lot more.
+
+Individual zram devices are configured and initialized using zramconfig
+userspace utility as shown in examples below. See zramconfig man page for
+more details.
+
+* Usage
+
+Following shows a typical sequence of steps for using zram.
+
+1) Load Modules:
+	modprobe zram num_devices=4
+	This creates 4 (uninitialized) devices: /dev/zram{0,1,2,3}
+	(num_devices parameter is optional. Default: 1)
+
+2) Initialize:
+	Use zramconfig utility to configure and initialize individual
+	zram devices. For example:
+	zramconfig /dev/zram0 --init # uses default value of disksize_kb
+	zramconfig /dev/zram1 --disksize_kb=102400 # 100MB /dev/zram1
+
+	*See zramconfig man page for more details and examples*
+
+3) Activate:
+	mkswap /dev/zram0
+	swapon /dev/zram0
+
+	mkfs.ext4 /dev/zram1
+	mount /dev/zram1 /tmp
+
+4) Stats:
+	zramconfig /dev/zram0 --stats
+	zramconfig /dev/zram1 --stats
+
+5) Deactivate:
+	swapoff /dev/zram0
+	umount /dev/zram1
+
+6) Reset:
+	zramconfig /dev/zram0 --reset
+	zramconfig /dev/zram1 --reset
+	(This frees memory allocated for the given device).
+
+
+Please report any problems at:
+ - Mailing list: linux-mm-cc at laptop dot org
+ - Issue tracker: http://code.google.com/p/compcache/issues/list
