+ depends on PCI
+ help
+ 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.

/**
- * This function provides low-level access to the IEEE1394 transaction
- * logic. Most C programs would use either fw_read(), fw_write() or
- * fw_lock() instead - those function are convenience wrappers for
- * this function. The fw_send_request() function is primarily
- * provided as a flexible, one-stop entry point for languages bindings
- * and protocol bindings.
+ * fw_send_request() - submit a request packet for transmission
+ * @card: interface to send the request at
+ * @t: transaction instance to which the request belongs
+ * @tcode: transaction code
+ * @destination_id: destination node ID, consisting of bus_ID and phy_ID
+ * @generation: bus generation in which request and response are valid
+ * @speed: transmission speed
+ * @offset: 48bit wide offset into destination's address space
+ * @payload: data payload for the request subaction
+ * @length: length of the payload, in bytes
+ * @callback: function to be called when the transaction is completed
+ * @callback_data: data to be passed to the transaction completion callback
*
- * FIXME: Document this function further, in particular the possible
- * values for rcode in the callback. In short, we map ACK_COMPLETE to
- * RCODE_COMPLETE, internal errors set errno and set rcode to
- * RCODE_SEND_ERROR (which is out of range for standard ieee1394
- * rcodes). All other rcodes are forwarded unchanged. For all
- * errors, payload is NULL, length is 0.
+ * Submit a request packet into the asynchronous request transmission queue.
+ * Can be called from atomic context. If you prefer a blocking API, use
+ * fw_run_transaction() in a context that can sleep.
*
- * Can not expect the callback to be called before the function
- * returns, though this does happen in some cases (ACK_COMPLETE and
- * errors).
+ * In case of lock requests, specify one of the firewire-core specific %TCODE_
+ * constants instead of %TCODE_LOCK_REQUEST in @tcode.
*
- * The payload is only used for write requests and must not be freed
- * until the callback has been called.
+ * Make sure that the value in @destination_id is not older than the one in
+ * @generation. Otherwise the request is in danger to be sent to a wrong node.
*
- * @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
- * @param callback_data pointer to arbitrary data, which will be
- * passed to the callback
- *
- * In case of asynchronous stream packets i.e. TCODE_STREAM_DATA, the caller
+ * In case of asynchronous stream packets i.e. %TCODE_STREAM_DATA, the caller
* 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.
+ *
+ * After the transaction is completed successfully or unsuccessfully, the
+ * @callback will be called. Among its parameters is the response code which
+ * is either one of the rcodes per IEEE 1394 or, in case of internal errors,
+ * 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
+ * generation, or missing ACK respectively.
+ *
+ * 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,
+ * transaction completion and hence execution of @callback may happen even
+ * before fw_send_request() returns.

- * This opcode is meant to set NV_PFB_CFG0 (0x100200) appropriately so
- * that the hardware can correctly calculate how much VRAM it has
- * (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() 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.

- * 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.

- * 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

-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.

- 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)

--- Changes --
-
- 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.

- * 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.
- *

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

-* 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).

+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>

-5. Step up and maintain this driver to ensure that it continues
+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

+ Linux DSP/BIOS Bridge release
+
+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]

+ 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.
+
+[EILSEQ]

+* Decouple hardware-specific code (e.g. bridge_brd_start/stop/delete/monitor)
+* DOFF binary loader: consider pushing to user space. at the very least
+ eliminate the direct filesystem access
+* Eliminate general services and libraries - use or extend existing kernel
+ libraries instead (e.g. gcf/lcm in nldr.c, global helpers in gen/)
+* Eliminate direct manipulation of OMAP_SYSC_BASE
+* Eliminate list.h : seem like a redundant wrapper to existing kernel lists
+* Eliminate DSP_SUCCEEDED macros and their imposed redundant indentations
+ (adopt the kernel way of checking for return values)
+* Audit interfaces exposed to user space
+* Audit and clean up header files folder
+* Use kernel coding style
+* checkpatch.pl fixes
+

+ * 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.

+ * DSP-BIOS Bridge driver support functions for TI OMAP processors.

+ * The Communication Memory Management(CMM) module provides shared memory
+ * management services for DSP/BIOS Bridge data streaming and messaging.
+ * Multiple shared memory segments can be registered with CMM. Memory is
+ * coelesced back to the appropriate pool when a buffer is freed.
+ *
+ * The CMM_Xlator[xxx] functions are used for node messaging and data
+ * streaming address translation to perform zero-copy inter-processor
+ * data transfer(GPP<->DSP). A "translator" object is created for a node or
+ * stream object that contains per thread virtual address information. This
+ * translator info is used at runtime to perform SM address translation
+ * to/from the DSP address space.
+ *
+ * Notes:
+ * cmm_xlator_alloc_buf - Used by Node and Stream modules for SM address

+ * This memory manager provides general heap management and arbitrary
+ * alignment for any number of memory segments.
+ *
+ * Notes:
+ *
+ * Memory blocks are allocated from the end of the first free memory
+ * block large enough to satisfy the request. Alignment requirements
+ * are satisfied by "sliding" the block forward until its base satisfies
+ * the alignment specification; if this is not possible then the next
+ * free block large enough to hold the request is tried.
+ *
+ * Since alignment can cause the creation of a new free block - the
+ * unused memory formed between the start of the original free block
+ * and the start of the allocated block - the memory manager must free
+ * this memory to prevent a memory leak.
+ *
+ * Overlay memory is managed by reserving through rmm_alloc, and freeing
+ * it through rmm_free. The memory manager prevents DSP code/data that is
+ * overlayed from being overwritten as long as the memory it runs at has
+ * been allocated, and not yet freed.

+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).

+ * 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.
