+	  Nosy is an IEEE 1394 packet sniffer that is used for protocol
+	  analysis and in development of IEEE 1394 drivers, applications,
+	  or firmwares.
+
+	  This driver lets you use a Texas Instruments PCILynx 1394 to PCI
+	  link layer controller TSB12LV21/A/B as a low-budget bus analyzer.
+	  PCILynx is a nowadays very rare IEEE 1394 controller which is
+	  not OHCI 1394 compliant.
+
+	  The following cards are known to be based on PCILynx or PCILynx-2:
+	  IOI IOI-1394TT (PCI card), Unibrain Fireboard 400 PCI Lynx-2
+	  (PCI card), Newer Technology FireWire 2 Go (CardBus card),
+	  Apple Power Mac G3 blue & white (onboard controller).
+
+	  To compile this driver as a module, say M here:  The module will be
+	  called nosy.  Source code of a userspace interface to nosy, called
+	  nosy-dump, can be found in tools/firewire/ of the kernel sources.
+
+	  If unsure, say N.

  *
- * @param card the card from which to send the request
- * @param tcode the tcode for this transaction.  Do not use
- *   TCODE_LOCK_REQUEST directly, instead use TCODE_LOCK_MASK_SWAP
- *   etc. to specify tcode and ext_tcode.
- * @param node_id the destination node ID (bus ID and PHY ID concatenated)
- * @param generation the generation for which node_id is valid
- * @param speed the speed to use for sending the request
- * @param offset the 48 bit offset on the destination node
- * @param payload the data payload for the request subaction
- * @param length the length in bytes of the data to read
- * @param callback function to be called when the transaction is completed

  * needs to synthesize @destination_id with fw_stream_packet_destination_id().
+ * It will contain tag, channel, and sy data instead of a node ID then.
+ *
+ * The payload buffer at @data is going to be DMA-mapped except in case of
+ * quadlet-sized payload or of local (loopback) requests.  Hence make sure that
+ * the buffer complies with the restrictions for DMA-mapped memory.  The
+ * @payload must not be freed before the @callback is called.

+ * In case of request types without payload, @data is NULL and @length is 0.

+ * the firewire-core specific %RCODE_SEND_ERROR.  The other firewire-core
+ * specific rcodes (%RCODE_CANCELLED, %RCODE_BUSY, %RCODE_GENERATION,
+ * %RCODE_NO_ACK) denote transaction timeout, busy responder, stale request

+ * Note some timing corner cases:  fw_send_request() may complete much earlier
+ * than when the request packet actually hits the wire.  On the other hand,

- *  - Occasionally, the entire register reads zero.
- *
- * To catch these, we read the register three times and ensure that the
- * difference between each two consecutive reads is approximately the same, i.e.
- * less than twice the other.  Furthermore, any negative difference indicates an
- * error.  (A PCI read should take at least 20 ticks of the 24.576 MHz timer to
- * execute, so we have enough precision to compute the ratio of the differences.)

-	 * (and subsequently report that value in NV_PFB_CSTATUS (0x10020C))

+	 * appropriately so that we can correctly calculate how much VRAM it
+	 * has (on nv10 and better chipsets the amount of installed VRAM is
+	 * subsequently reported in NV_PFB_CSTATUS (0x10020C)).
 	 *
-	 * The implementation of this opcode in general consists of two parts:
-	 * 1) determination of the memory bus width
-	 * 2) determination of how many of the card's RAM pads have ICs attached
+	 * The implementation of this opcode in general consists of several
+	 * parts:
 	 *
-	 * 1) is done by a cunning combination of writes to offsets 0x1c and
-	 * 0x3c in the framebuffer, and seeing whether the written values are
-	 * read back correctly. This then affects bits 4-7 of NV_PFB_CFG0
+	 * 1) Determination of memory type and density. Only necessary for
+	 *    really old chipsets, the memory type reported by the strap bits
+	 *    (0x101000) is assumed to be accurate on nv05 and newer.
 	 *
-	 * 2) is done by a cunning combination of writes to an offset slightly
-	 * less than the maximum memory reported by NV_PFB_CSTATUS, then seeing
-	 * if the test pattern can be read back. This then affects bits 12-15 of
-	 * NV_PFB_CFG0
+	 * 2) Determination of the memory bus width. Usually done by a cunning
+	 *    combination of writes to offsets 0x1c and 0x3c in the fb, and
+	 *    seeing whether the written values are read back correctly.
 	 *
-	 * In this context a "cunning combination" may include multiple reads
-	 * and writes to varying locations, often alternating the test pattern
-	 * and 0, doubtless to make sure buffers are filled, residual charges
-	 * on tracks are removed etc.
+	 *    Only necessary on nv0x-nv1x and nv34, on the other cards we can
+	 *    trust the straps.
 	 *
-	 * Unfortunately, the "cunning combination"s mentioned above, and the
-	 * changes to the bits in NV_PFB_CFG0 differ with nearly every bios
-	 * trace I have.
+	 * 3) Determination of how many of the card's RAM pads have ICs
+	 *    attached, usually done by a cunning combination of writes to an
+	 *    offset slightly less than the maximum memory reported by
+	 *    NV_PFB_CSTATUS, then seeing if the test pattern can be read back.
 	 *
-	 * Therefore, we cheat and assume the value of NV_PFB_CFG0 with which
-	 * we started was correct, and use that instead
+	 * This appears to be a NOP on IGPs and NV4x or newer chipsets, both io

+/* Some general notes on the atomic requirements of VIDIOC_G/TRY/S_EXT_CTRLS:
+
+   It is not a fully atomic operation, just best-effort only. After all, if
+   multiple controls have to be set through multiple i2c writes (for example)
+   then some initial writes may succeed while others fail. Thus leaving the
+   system in an inconsistent state. The question is how much effort you are
+   willing to spend on trying to make something atomic that really isn't.
+
+   From the point of view of an application the main requirement is that
+   when you call VIDIOC_S_EXT_CTRLS and some values are invalid then an
+   error should be returned without actually affecting any controls.
+
+   If all the values are correct, then it is acceptable to just give up
+   in case of low-level errors.
+
+   It is important though that the application can tell when only a partial
+   configuration was done. The way we do that is through the error_idx field
+   of struct v4l2_ext_controls: if that is equal to the count field then no
+   controls were affected. Otherwise all controls before that index were
+   successful in performing their 'get' or 'set' operation, the control at
+   the given index failed, and you don't know what happened with the controls
+   after the failed one. Since if they were part of a control cluster they
+   could have been successfully processed (if a cluster member was encountered
+   at index < error_idx), they could have failed (if a cluster member was at
+   error_idx), or they may not have been processed yet (if the first cluster
+   member appeared after error_idx).
+
+   It is all fairly theoretical, though. In practice all you can do is to
+   bail out. If error_idx == count, then it is an application bug. If
+   error_idx < count then it is only an application bug if the error code was
+   EBUSY. That usually means that something started streaming just when you
+   tried to set the controls. In all other cases it is a driver/hardware
+   problem and all you can do is to retry or bail out.
+
+   Note that these rules do not apply to VIDIOC_TRY_EXT_CTRLS: since that
+   never modifies controls the error_idx is just set to whatever control
+   has an invalid value.

+/*  Copyright (c) 2010  Christoph Mair <christoph.mair@gmail.com>
+
+    This driver supports the bmp085 digital barometric pressure
+    and temperature sensor from Bosch Sensortec. The datasheet
+    is avaliable from their website:
+    http://www.bosch-sensortec.com/content/language1/downloads/BST-BMP085-DS000-05.pdf
+
+    A pressure measurement is issued by reading from pressure0_input.
+    The return value ranges from 30000 to 110000 pascal with a resulution
+    of 1 pascal (0.01 millibar) which enables measurements from 9000m above
+    to 500m below sea level.
+
+    The temperature can be read from temp0_input. Values range from
+    -400 to 850 representing the ambient temperature in degree celsius
+    multiplied by 10.The resolution is 0.1 celsius.
+
+    Because ambient pressure is temperature dependent, a temperature
+    measurement will be executed automatically even if the user is reading
+    from pressure0_input. This happens if the last temperature measurement
+    has been executed more then one second ago.
+
+    To decrease RMS noise from pressure measurements, the bmp085 can
+    autonomously calculate the average of up to eight samples. This is
+    set up by writing to the oversampling sysfs file. Accepted values
+    are 0, 1, 2 and 3. 2^x when x is the value written to this file
+    specifies the number of samples used to calculate the ambient pressure.
+    RMS noise is specified with six pascal (without averaging) and decreases
+    down to 3 pascal when using an oversampling setting of 3.

-    bind_request() and bind_device() are merged by now. Register_client()

-
-    bind_request() connects a socket to a particular client driver.
-    It looks up the specified device ID in the list of registered
-    drivers, binds it to the socket, and tries to create an instance
-    of the device.  unbind_request() deletes a driver instance.
-
-    Bind_device() associates a device driver with a particular socket.
-    It is normally called by Driver Services after it has identified
-    a newly inserted card.  An instance of that driver will then be
-    eligible to register as a client of this socket.
-
-    Register_client() uses the dev_info_t handle to match the
-    caller with a socket.  The driver must have already been bound
-    to a socket with bind_device() -- in fact, bind_device()
-    allocates the client structure that will be used.

+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.

- * The previous block comment is used to automatically generate

- *
- * Driver: the name of the driver
- * Description: a short phrase describing the driver.  Don't list boards.
- * Devices: a full list of the boards that attempt to be supported by
- *   the driver.  Format is "(manufacturer) board name [comedi name]",
- *   where comedi_name is the name that is used to configure the board.
- *   See the comment near board_name: in the struct comedi_driver structure
- *   below.  If (manufacturer) or [comedi name] is missing, the previous
- *   value is used.
- * Author: you
- * Updated: date when the _documentation_ was last updated.  Use 'date -R'
- *   to get a value for this.
- * Status: a one-word description of the status.  Valid values are:
- *   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.

- * Driver: the name of the driver
- * Description: a short phrase describing the driver.  Don't list boards.
- * Devices: a full list of the boards that attempt to be supported by
- *   the driver.  Format is "(manufacturer) board name [comedi name]",
- *   where comedi_name is the name that is used to configure the board.

- *   value is used.
- * Author: you
- * Updated: date when the _documentation_ was last updated.  Use 'date -R'
- *   to get a value for this.
- * Status: a one-word description of the status.  Valid values are:
- *   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.
-
-Options for PCL-812:
-  [0] - IO Base
-  [1] - IRQ  (0=disable, 2, 3, 4, 5, 6, 7; 10, 11, 12, 14, 15)

+ * 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.

-The allocator shown here  exploits high memory. This document explains
-how  a user can  deal   with drivers uses   this  allocator and how  a
-programmer can link in the module.
-
-The module is being used by my pxc and pxdrv device drivers (as well as
-other ones), available from ftp.systemy.it/pub/develop and
-ftp.linux.it/pub/People/Rubini
-
-	User's manual
-	=============
-
-
-One of the most compelling problems with any DMA-capable device is the
-allocation  of a suitable  memory buffer. The "allocator" module tries
-to deal with  the problem in  a clean way.  The module is  able to use
-high   memory  (above the  one   used in  normal   operation)  for DMA
-allocation.
-
-To prevent  the  kernel for using   high memory,  so  that it  remains
-available for  DMA, you should  pass a  command  line argument to  the
-kernel.  Command line arguments  can be passed to  Lilo, to Loadlin or
-to whichever loader  you are using  (unless it's very poor in design).
-For Lilo, either use  "append=" in  /etc/lilo.conf or add  commandline
-arguments to the  interactive prompt. For  example, I have a 32MB  box
-and reserve two megs for DMA:
-
-In lilo.conf:
-	image = /zImage
-	label = linux
-	append = "mem=30M"
-
-Or, interactively:
-	LILO: linux mem=30M
-
-Once  the kernel is booted  with the  right command-line argument, any
-driver  linked   with  the  allocator   module  will  be able   to get
-DMA-capable memory without  much  trouble (unless the  various drivers
-need more memory than available).
-
-The module implements an alloc/free  mechanism,  so that it can  serve
-multiple drivers  at the  same time. Note  however that  the allocator
-uses all of  high memory and assumes to  be the only piece of software
-using such memory.
-
-
-	Programmer's manual
-	===================
-
-The allocator,  as  released, is designed  to  be linked  to  a device
-driver.  In this  case, the driver  must call allocator_init()  before
-using   the  allocator   and  must  call   allocator_cleanup()  before
-unloading.  This is  usually  done   from within  init_module()    and
-cleanup_module(). If the allocator is linked to  a driver, it won't be
-possible for several drivers to allocate high DMA memory, as explained
-above.
-
-It is possible, on the other hand, to compile the module as a standalone
-module, so that several modules can rely on the allocator for they DMA
-buffers. To compile the allocator as a standalone module, do the
-following in this directory (or provide a suitable Makefile, or edit
-the source code):
-
-	make allocator.o CC="gcc -Dallocator_init=init_module -Dallocator_cleanup=cleanup_module -include /usr/include/linux/module.h"
-
-The previous commandline  tells   to include <linux/module.h>  in  the
-first place,  and to rename the init  and cleanup function to the ones
-needed for  module loading and  unloading.  Drivers using a standalone
-allocator won't need to call allocator_init() nor allocator_cleanup().
-
-The allocator exports the following functions (declared in allocator.h):
-
-   unsigned long allocator_allocate_dma (unsigned long kilobytes,
-					 int priority);
-
-	This function returns a physical address, over high_memory,
-	which corresponds to an area of at least "kilobytes" kilobytes.
-	The area will be owned by the module calling the function.
-	The returned address can be passed to device boards, to instruct
-	their DMA controllers, via phys_to_bus(). The address can be used
-	by C code after vremap()/ioremap(). The "priority" argument should
-	be GFP_KERNEL or GFP_ATOMIC, according to the context of the
-	caller; it is used to call kmalloc(), as the allocator must keep
-	track of any region it gives away. In case of error the function
-	returns 0, and the caller is expected to issue a -ENOMEM error.
-
-
-   void allocator_free_dma (unsigned long address);
-
-	This function is the reverse of the previous one. If a driver
-	doesn't free the DMA memory it allocated, the allocator will
-	consider such memory as busy. Note, however, that
-	allocator_cleanup() calls kfree() on every region it reclaimed,
-	so that a driver with the allocator linked in can avoid calling
-	allocator_free_dma() at unload time.

-  Date	      Programmer  Description of changes made
-  -------------------------------------------------------------------
-  02-Aug-2002 NJC         allocator now steps in 1MB increments, rather
-			  than doubling its size each time.
-			  Also, allocator_init(u32 *) now returns
-			  (in the first arg) the size of the free
-			  space.  This is no longer consistent with
-			  using the allocator as a module, and some changes
-			  may be necessary for that purpose.  This was
-			  designed to work with the DT3155 driver, in
-			  stand alone mode only!!!
-  26-Oct-2009 SS	  Port to 2.6.30 kernel.

-  03-Jul-2000 JML       n/a
-  10-Oct-2001 SS        port to 2.4 kernel
-  02-Apr-2002 SS        Mods to use allocator as a standalone module;
-                        Merged John Roll's changes (john@cfa.harvard.edu)
-                        to make work with multiple boards.
-  02-Jul-2002 SS        Merged James Rose's chages (rosejr@purdue.edu) to:
-                         * fix successive interrupt-driven captures
-                         * add select/poll support.
-  10-Jul-2002 GCS       Add error check when ndevices > MAXBOARDS.
-  02-Aug-2002 GCS       Fix field mode so that odd (lower) field is stored
-                        in lower half of buffer.
-  05-Aug-2005 SS        port to 2.6 kernel.
-  26-Oct-2009 SS	port to 2.6.30 kernel.
-
--- Notes --
-
-** appended "mem=124" in lilo.conf to allow for 4megs free on my 128meg system.
- * using allocator.c and allocator.h from o'reilly book (alessandro rubini)
-    ftp://ftp.systemy.it/pub/develop (see README.allocator)
-
- + might want to get rid of MAXboards for allocating initial buffer.
-    confusing and not necessary
-
- + in cleanup_module the MOD_IN_USE looks like it is check after it should
-
- * GFP_DMA should not be set with a PCI system (pg 291)
-
- - NJC why are only two buffers allowed? (see isr, approx line 358)

-  Date       Programmer  Description of changes made
-  -------------------------------------------------------------------
-  03-Jul-2000 JML       n/a
-  02-Apr-2002 SS        Mods to make work with separate allocator
-			module; Merged John Roll's mods to make work with
-			multiple boards.
-  10-Jul-2002 GCS       Complete rewrite of setup_buffers to disallow
-			buffers which span a 4MB boundary.
-  24-Jul-2002 SS        GPL licence.
-  30-Jul-2002 NJC       Added support for buffer loop.
-  31-Jul-2002 NJC       Complete rewrite of buffer management
-  02-Aug-2002 NJC       Including slab.h instead of malloc.h (no warning).
-			Also, allocator_init() now returns allocator_max
-			so cleaned up allocate_buffers() accordingly.
-  08-Aug-2005 SS        port to 2.6 kernel.

+
+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.

 really have people help them out on the "clean" ar9170 driver that can
 be found at the linux-wireless developer site.
 
-But, if you wish to clean up this driver instead, here's a short list of
-things that need to be done to get it into a more mergable shape:
-
-TODO:
-	- checkpatch.pl cleanups
-	- sparse cleanups
-	- port to in-kernel 80211 stack
-	- review by the wireless developer community
-
-Please send any patches to Greg Kroah-Hartman <greg@kroah.com> and
-Luis Rodriguez <Luis.Rodriguez@Atheros.com> and the
-otus-devel@lists.madwifi-project.org mailing list.
+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
+can be removed.

-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).
-
-
-Please report any problems at:
- - Mailing list: linux-mm-cc at laptop dot org
- - Issue tracker: http://code.google.com/p/compcache/issues/list

+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>

+1. Step up and maintain this driver to ensure that it continues
 to work.  Having the hardware for this is pretty much a
 requirement.  If this does not happen, the will be removed in

+
+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]
+    I/O is currently pending.
+
+    - End of stream was already requested on this output channel.
+
+[EDOM]
+    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.
+
+[ETIME]
+    A timeout occurred before the requested operation could complete.
+
+[ENOSR]
+    A stream has been issued the maximum number of buffers allowed in the
+    stream at once; buffers must be reclaimed from the stream before any more
+    can be issued.
+
+    - No free channels are available.

+ *  post_swi -       Set to 1 by the GPP after it has written the messages,
+ *                  set the size, and set buf_empty to FALSE.
+ *                  The DSP Host driver uses SWI_andn of the post_swi field
+ *                  when a host interrupt occurs. The host driver clears
+ *                  this after posting the SWI.
+ *  size -          Number of messages to be read by the DSP.
+ *
+ *  For messages from the DSP:
+ *  buf_empty -      This flag is set to FALSE by the DSP after it has output
+ *                  messages for the GPP. The DPC on the GPP sets it to
+ *                  TRUE after it has copied the messages.

+ * 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).
+

+ - Mailing list: linux-mm-cc at laptop dot org

+ * The OCTEON watchdog has a maximum timeout of 2^32 * io_clock.
+ * For most systems this is less than 10 seconds, so to allow for
+ * software to request longer watchdog heartbeats, we maintain software
+ * counters to count multiples of the base rate.  If the system locks
+ * up in such a manner that we can not run the software counters, the
+ * only result is a watchdog reset sooner than was requested.  But
+ * that is OK, because in this case userspace would likely not be able
+ * to do anything anyhow.
+ *
+ * The hardware watchdog interval we call the period.  The OCTEON
+ * watchdog goes through several stages, after the first period an
+ * irq is asserted, then if it is not reset, after the next period NMI
+ * is asserted, then after an additional period a chip wide soft reset.
+ * So for the software counters, we reset watchdog after each period
+ * and decrement the counter.  But for the last two periods we need to
+ * let the watchdog progress to the NMI stage so we disable the irq
+ * and let it proceed.  Once in the NMI, we print the register state
+ * to the serial port and then wait for the reset.
+ *
+ * A watchdog is maintained for each CPU in the system, that way if
+ * one CPU suffers a lockup, we also get a register dump and reset.
+ * The userspace ping resets the watchdog on all CPUs.
+ *
+ * Before userspace opens the watchdog device, we still run the
+ * watchdogs to catch any lockups that may be kernel related.

+ * PV guests under Xen are running in an non-contiguous memory architecture.
+ *
+ * When PCI pass-through is utilized, this necessitates an IOMMU for
+ * translating bus (DMA) to virtual and vice-versa and also providing a
+ * mechanism to have contiguous pages for device drivers operations (say DMA
+ * operations).
+ *
+ * Specifically, under Xen the Linux idea of pages is an illusion. It
+ * assumes that pages start at zero and go up to the available memory. To
+ * help with that, the Linux Xen MMU provides a lookup mechanism to
+ * translate the page frame numbers (PFN) to machine frame numbers (MFN)
+ * and vice-versa. The MFN are the "real" frame numbers. Furthermore
+ * memory is not contiguous. Xen hypervisor stitches memory for guests
+ * from different pools, which means there is no guarantee that PFN==MFN
+ * and PFN+1==MFN+1. Lastly with Xen 4.0, pages (in debug mode) are
+ * allocated in descending order (high to low), meaning the guest might
+ * never get any MFN's under the 4GB mark.
