+The aacraid driver adds support for Adaptec (http://www.adaptec.com)
+RAID controllers. This is a major rewrite from the original
+Adaptec supplied driver. It has signficantly cleaned up both the code
+and the running binary size (the module is less than half the size of
+the original).

+spi_butterfly - parport-to-butterfly adapter driver
+===================================================
+
+This is a hardware and software project that includes building and using
+a parallel port adapter cable, together with an "AVR Butterfly" to run
+firmware for user interfacing and/or sensors. A Butterfly is a $US20
+battery powered card with an AVR microcontroller and lots of goodies:
+sensors, LCD, flash, toggle stick, and more. You can use AVR-GCC to
+develop firmware for this, and flash it using this adapter cable.
+
+You can make this adapter from an old printer cable and solder things
+directly to the Butterfly. Or (if you have the parts and skills) you
+can come up with something fancier, providing ciruit protection to the
+Butterfly and the printer port, or with a better power supply than two
+signal pins from the printer port.
+
+
+The first cable connections will hook Linux up to one SPI bus, with the
+AVR and a DataFlash chip; and to the AVR reset line. This is all you
+need to reflash the firmware, and the pins are the standard Atmel "ISP"
+connector pins (used also on non-Butterfly AVR boards).
+
+ Signal Butterfly Parport (DB-25)
+ ------ --------- ---------------
+ SCK = J403.PB1/SCK = pin 2/D0
+ RESET = J403.nRST = pin 3/D1
+ VCC = J403.VCC_EXT = pin 8/D6
+ MOSI = J403.PB2/MOSI = pin 9/D7
+ MISO = J403.PB3/MISO = pin 11/S7,nBUSY
+ GND = J403.GND = pin 23/GND
+
+Then to let Linux master that bus to talk to the DataFlash chip, you must
+(a) flash new firmware that disables SPI (set PRR.2, and disable pullups
+by clearing PORTB.[0-3]); (b) configure the mtd_dataflash driver; and
+(c) cable in the chipselect.
+
+ Signal Butterfly Parport (DB-25)
+ ------ --------- ---------------
+ VCC = J400.VCC_EXT = pin 7/D5
+ SELECT = J400.PB0/nSS = pin 17/C3,nSELECT
+ GND = J400.GND = pin 24/GND
+
+The "USI" controller, using J405, can be used for a second SPI bus. That
+would let you talk to the AVR over SPI, running firmware that makes it act
+as an SPI slave, while letting either Linux or the AVR use the DataFlash.
+There are plenty of spare parport pins to wire this one up, such as:

+Overview of Linux kernel SPI support
+====================================
+
+02-Dec-2005
+
+What is SPI?
+------------
+The "Serial Peripheral Interface" (SPI) is a synchronous four wire serial
+link used to connect microcontrollers to sensors, memory, and peripherals.
+
+The three signal wires hold a clock (SCLK, often on the order of 10 MHz),
+and parallel data lines with "Master Out, Slave In" (MOSI) or "Master In,
+Slave Out" (MISO) signals. (Other names are also used.) There are four
+clocking modes through which data is exchanged; mode-0 and mode-3 are most
+commonly used. Each clock cycle shifts data out and data in; the clock
+doesn't cycle except when there is data to shift.
+
+SPI masters may use a "chip select" line to activate a given SPI slave
+device, so those three signal wires may be connected to several chips
+in parallel. All SPI slaves support chipselects. Some devices have
+other signals, often including an interrupt to the master.
+
+Unlike serial busses like USB or SMBUS, even low level protocols for
+SPI slave functions are usually not interoperable between vendors
+(except for cases like SPI memory chips).
+
+ - SPI may be used for request/response style device protocols, as with
+ touchscreen sensors and memory chips.
+
+ - It may also be used to stream data in either direction (half duplex),
+ or both of them at the same time (full duplex).
+
+ - Some devices may use eight bit words. Others may different word
+ lengths, such as streams of 12-bit or 20-bit digital samples.
+
+In the same way, SPI slaves will only rarely support any kind of automatic
+discovery/enumeration protocol. The tree of slave devices accessible from
+a given SPI master will normally be set up manually, with configuration
+tables.
+
+SPI is only one of the names used by such four-wire protocols, and
+most controllers have no problem handling "MicroWire" (think of it as
+half-duplex SPI, for request/response protocols), SSP ("Synchronous
+Serial Protocol"), PSP ("Programmable Serial Protocol"), and other
+related protocols.
+
+Microcontrollers often support both master and slave sides of the SPI
+protocol. This document (and Linux) currently only supports the master
+side of SPI interactions.
+
+
+Who uses it? On what kinds of systems?
+---------------------------------------
+Linux developers using SPI are probably writing device drivers for embedded
+systems boards. SPI is used to control external chips, and it is also a
+protocol supported by every MMC or SD memory card. (The older "DataFlash"
+cards, predating MMC cards but using the same connectors and card shape,
+support only SPI.) Some PC hardware uses SPI flash for BIOS code.
+
+SPI slave chips range from digital/analog converters used for analog
+sensors and codecs, to memory, to peripherals like USB controllers
+or Ethernet adapters; and more.
+
+Most systems using SPI will integrate a few devices on a mainboard.
+Some provide SPI links on expansion connectors; in cases where no
+dedicated SPI controller exists, GPIO pins can be used to create a
+low speed "bitbanging" adapter. Very few systems will "hotplug" an SPI
+controller; the reasons to use SPI focus on low cost and simple operation,
+and if dynamic reconfiguration is important, USB will often be a more
+appropriate low-pincount peripheral bus.
+
+Many microcontrollers that can run Linux integrate one or more I/O
+interfaces with SPI modes. Given SPI support, they could use MMC or SD
+cards without needing a special purpose MMC/SD/SDIO controller.
+
+
+How do these driver programming interfaces work?
+------------------------------------------------
+The <linux/spi/spi.h> header file includes kerneldoc, as does the
+main source code, and you should certainly read that. This is just
+an overview, so you get the big picture before the details.
+
+SPI requests always go into I/O queues. Requests for a given SPI device
+are always executed in FIFO order, and complete asynchronously through
+completion callbacks. There are also some simple synchronous wrappers
+for those calls, including ones for common transaction types like writing
+a command and then reading its response.
+
+There are two types of SPI driver, here called:
+
+ Controller drivers ... these are often built in to System-On-Chip
+ processors, and often support both Master and Slave roles.
+ These drivers touch hardware registers and may use DMA.
+ Or they can be PIO bitbangers, needing just GPIO pins.
+
+ Protocol drivers ... these pass messages through the controller
+ driver to communicate with a Slave or Master device on the
+ other side of an SPI link.
+
+So for example one protocol driver might talk to the MTD layer to export
+data to filesystems stored on SPI flash like DataFlash; and others might
+control audio interfaces, present touchscreen sensors as input interfaces,
+or monitor temperature and voltage levels during industrial processing.
+And those might all be sharing the same controller driver.
+
+A "struct spi_device" encapsulates the master-side interface between
+those two types of driver. At this writing, Linux has no slave side
+programming interface.
+
+There is a minimal core of SPI programming interfaces, focussing on
+using driver model to connect controller and protocol drivers using
+device tables provided by board specific initialization code. SPI
+shows up in sysfs in several locations:
+
+ /sys/devices/.../CTLR/spiB.C ... spi_device for on bus "B",
+ chipselect C, accessed through CTLR.
+
+ /sys/devices/.../CTLR/spiB.C/modalias ... identifies the driver
+ that should be used with this device (for hotplug/coldplug)
+
+ /sys/bus/spi/devices/spiB.C ... symlink to the physical
+ spiB-C device
+
+ /sys/bus/spi/drivers/D ... driver for one or more spi*.* devices
+
+ /sys/class/spi_master/spiB ... class device for the controller
+ managing bus "B". All the spiB.* devices share the same
+ physical SPI bus segment, with SCLK, MOSI, and MISO.
+
+
+How does board-specific init code declare SPI devices?
+------------------------------------------------------
+Linux needs several kinds of information to properly configure SPI devices.
+That information is normally provided by board-specific code, even for
+chips that do support some of automated discovery/enumeration.
+
+DECLARE CONTROLLERS
+
+The first kind of information is a list of what SPI controllers exist.
+For System-on-Chip (SOC) based boards, these will usually be platform
+devices, and the controller may need some platform_data in order to
+operate properly. The "struct platform_device" will include resources
+like the physical address of the controller's first register and its IRQ.
+
+Platforms will often abstract the "register SPI controller" operation,
+maybe coupling it with code to initialize pin configurations, so that
+the arch/.../mach-*/board-*.c files for several boards can all share the
+same basic controller setup code. This is because most SOCs have several
+SPI-capable controllers, and only the ones actually usable on a given
+board should normally be set up and registered.
+
+So for example arch/.../mach-*/board-*.c files might have code like:
+
+ #include <asm/arch/spi.h> /* for mysoc_spi_data */
+
+ /* if your mach-* infrastructure doesn't support kernels that can
+ * run on multiple boards, pdata wouldn't benefit from "__init".
+ */
+ static struct mysoc_spi_data __init pdata = { ... };
+
+ static __init board_init(void)
+ {
+ ...
+ /* this board only uses SPI controller #2 */
+ mysoc_register_spi(2, &pdata);
+ ...
+ }
+
+And SOC-specific utility code might look something like:
+
+ #include <asm/arch/spi.h>
+
+ static struct platform_device spi2 = { ... };
+
+ void mysoc_register_spi(unsigned n, struct mysoc_spi_data *pdata)
+ {
+ struct mysoc_spi_data *pdata2;
+
+ pdata2 = kmalloc(sizeof *pdata2, GFP_KERNEL);
+ *pdata2 = pdata;
+ ...
+ if (n == 2) {
+ spi2->dev.platform_data = pdata2;
+ register_platform_device(&spi2);
+
+ /* also: set up pin modes so the spi2 signals are
+ * visible on the relevant pins ... bootloaders on
+ * production boards may already have done this, but
+ * developer boards will often need Linux to do it.
+ */
+ }
+ ...
+ }
+
+Notice how the platform_data for boards may be different, even if the
+same SOC controller is used. For example, on one board SPI might use
+an external clock, where another derives the SPI clock from current
+settings of some master clock.
+
+
+DECLARE SLAVE DEVICES
+
+The second kind of information is a list of what SPI slave devices exist
+on the target board, often with some board-specific data needed for the
+driver to work correctly.
+
+Normally your arch/.../mach-*/board-*.c files would provide a small table
+listing the SPI devices on each board. (This would typically be only a
+small handful.) That might look like:
+
+ static struct ads7846_platform_data ads_info = {
+ .vref_delay_usecs = 100,
+ .x_plate_ohms = 580,
+ .y_plate_ohms = 410,
+ };
+
+ static struct spi_board_info spi_board_info[] __initdata = {
+ {
+ .modalias = "ads7846",
+ .platform_data = &ads_info,
+ .mode = SPI_MODE_0,
+ .irq = GPIO_IRQ(31),
+ .max_speed_hz = 120000 /* max sample rate at 3V */ * 16,
+ .bus_num = 1,
+ .chip_select = 0,
+ },
+ };
+
+Again, notice how board-specific information is provided; each chip may need
+several types. This example shows generic constraints like the fastest SPI
+clock to allow (a function of board voltage in this case) or how an IRQ pin
+is wired, plus chip-specific constraints like an important delay that's
+changed by the capacitance at one pin.
+
+(There's also "controller_data", information that may be useful to the
+controller driver. An example would be peripheral-specific DMA tuning
+data or chipselect callbacks. This is stored in spi_device later.)
+
+The board_info should provide enough information to let the system work
+without the chip's driver being loaded. The most troublesome aspect of
+that is likely the SPI_CS_HIGH bit in the spi_device.mode field, since
+sharing a bus with a device that interprets chipselect "backwards" is
+not possible.
+
+Then your board initialization code would register that table with the SPI
+infrastructure, so that it's available later when the SPI master controller
+driver is registered:
+
+ spi_register_board_info(spi_board_info, ARRAY_SIZE(spi_board_info));
+
+Like with other static board-specific setup, you won't unregister those.
+
+The widely used "card" style computers bundle memory, cpu, and little else
+onto a card that's maybe just thirty square centimeters. On such systems,
+your arch/.../mach-.../board-*.c file would primarily provide information
+about the devices on the mainboard into which such a card is plugged. That
+certainly includes SPI devices hooked up through the card connectors!
+
+
+NON-STATIC CONFIGURATIONS
+
+Developer boards often play by different rules than product boards, and one
+example is the potential need to hotplug SPI devices and/or controllers.
+
+For those cases you might need to use use spi_busnum_to_master() to look
+up the spi bus master, and will likely need spi_new_device() to provide the
+board info based on the board that was hotplugged. Of course, you'd later
+call at least spi_unregister_device() when that board is removed.
+
+When Linux includes support for MMC/SD/SDIO/DataFlash cards through SPI, those
+configurations will also be dynamic. Fortunately, those devices all support
+basic device identification probes, so that support should hotplug normally.
+
+
+How do I write an "SPI Protocol Driver"?
+----------------------------------------
+All SPI drivers are currently kernel drivers. A userspace driver API
+would just be another kernel driver, probably offering some lowlevel
+access through aio_read(), aio_write(), and ioctl() calls and using the
+standard userspace sysfs mechanisms to bind to a given SPI device.
+
+SPI protocol drivers somewhat resemble platform device drivers:
+
+ static struct spi_driver CHIP_driver = {
+ .driver = {
+ .name = "CHIP",
+ .bus = &spi_bus_type,
+ .owner = THIS_MODULE,
+ },
+
+ .probe = CHIP_probe,
+ .remove = __devexit_p(CHIP_remove),
+ .suspend = CHIP_suspend,
+ .resume = CHIP_resume,
+ };
+
+The driver core will autmatically attempt to bind this driver to any SPI
+device whose board_info gave a modalias of "CHIP". Your probe() code
+might look like this unless you're creating a class_device:
+
+ static int __devinit CHIP_probe(struct spi_device *spi)
+ {
+ struct CHIP *chip;
+ struct CHIP_platform_data *pdata;
+
+ /* assuming the driver requires board-specific data: */
+ pdata = &spi->dev.platform_data;
+ if (!pdata)
+ return -ENODEV;
+
+ /* get memory for driver's per-chip state */
+ chip = kzalloc(sizeof *chip, GFP_KERNEL);
+ if (!chip)
+ return -ENOMEM;
+ dev_set_drvdata(&spi->dev, chip);
+
+ ... etc
+ return 0;
+ }
+
+As soon as it enters probe(), the driver may issue I/O requests to
+the SPI device using "struct spi_message". When remove() returns,
+the driver guarantees that it won't submit any more such messages.
+
+ - An spi_message is a sequence of of protocol operations, executed
+ as one atomic sequence. SPI driver controls include:
+
+ + when bidirectional reads and writes start ... by how its
+ sequence of spi_transfer requests is arranged;
+
+ + optionally defining short delays after transfers ... using
+ the spi_transfer.delay_usecs setting;
+
+ + whether the chipselect becomes inactive after a transfer and
+ any delay ... by using the spi_transfer.cs_change flag;
+
+ + hinting whether the next message is likely to go to this same
+ device ... using the spi_transfer.cs_change flag on the last
+ transfer in that atomic group, and potentially saving costs
+ for chip deselect and select operations.
+
+ - Follow standard kernel rules, and provide DMA-safe buffers in
+ your messages. That way controller drivers using DMA aren't forced
+ to make extra copies unless the hardware requires it (e.g. working
+ around hardware errata that force the use of bounce buffering).
+
+ If standard dma_map_single() handling of these buffers is inappropriate,
+ you can use spi_message.is_dma_mapped to tell the controller driver
+ that you've already provided the relevant DMA addresses.
+
+ - The basic I/O primitive is spi_async(). Async requests may be
+ issued in any context (irq handler, task, etc) and completion
+ is reported using a callback provided with the message.
+ After any detected error, the chip is deselected and processing
+ of that spi_message is aborted.
+
+ - There are also synchronous wrappers like spi_sync(), and wrappers
+ like spi_read(), spi_write(), and spi_write_then_read(). These
+ may be issued only in contexts that may sleep, and they're all
+ clean (and small, and "optional") layers over spi_async().
+
+ - The spi_write_then_read() call, and convenience wrappers around
+ it, should only be used with small amounts of data where the
+ cost of an extra copy may be ignored. It's designed to support
+ common RPC-style requests, such as writing an eight bit command
+ and reading a sixteen bit response -- spi_w8r16() being one its
+ wrappers, doing exactly that.
+
+Some drivers may need to modify spi_device characteristics like the
+transfer mode, wordsize, or clock rate. This is done with spi_setup(),
+which would normally be called from probe() before the first I/O is
+done to the device.
+
+While "spi_device" would be the bottom boundary of the driver, the
+upper boundaries might include sysfs (especially for sensor readings),
+the input layer, ALSA, networking, MTD, the character device framework,
+or other Linux subsystems.
+
+Note that there are two types of memory your driver must manage as part
+of interacting with SPI devices.
+
+ - I/O buffers use the usual Linux rules, and must be DMA-safe.
+ You'd normally allocate them from the heap or free page pool.
+ Don't use the stack, or anything that's declared "static".
+
+ - The spi_message and spi_transfer metadata used to glue those
+ I/O buffers into a group of protocol transactions. These can
+ be allocated anywhere it's convenient, including as part of
+ other allocate-once driver data structures. Zero-init these.
+
+If you like, spi_message_alloc() and spi_message_free() convenience
+routines are available to allocate and zero-initialize an spi_message
+with several transfers.
+
+
+How do I write an "SPI Master Controller Driver"?
+-------------------------------------------------
+An SPI controller will probably be registered on the platform_bus; write
+a driver to bind to the device, whichever bus is involved.
+
+The main task of this type of driver is to provide an "spi_master".
+Use spi_alloc_master() to allocate the master, and class_get_devdata()
+to get the driver-private data allocated for that device.
+
+ struct spi_master *master;
+ struct CONTROLLER *c;
+
+ master = spi_alloc_master(dev, sizeof *c);
+ if (!master)
+ return -ENODEV;
+
+ c = class_get_devdata(&master->cdev);
+
+The driver will initialize the fields of that spi_master, including the
+bus number (maybe the same as the platform device ID) and three methods
+used to interact with the SPI core and SPI protocol drivers. It will
+also initialize its own internal state.
+
+ master->setup(struct spi_device *spi)
+ This sets up the device clock rate, SPI mode, and word sizes.
+ Drivers may change the defaults provided by board_info, and then
+ call spi_setup(spi) to invoke this routine. It may sleep.
+
+ master->transfer(struct spi_device *spi, struct spi_message *message)
+ This must not sleep. Its responsibility is arrange that the
+ transfer happens and its complete() callback is issued; the two
+ will normally happen later, after other transfers complete.
+
+ master->cleanup(struct spi_device *spi)
+ Your controller driver may use spi_device.controller_state to hold
+ state it dynamically associates with that device. If you do that,
+ be sure to provide the cleanup() method to free that state.
+
+The bulk of the driver will be managing the I/O queue fed by transfer().
+
+That queue could be purely conceptual. For example, a driver used only
+for low-frequency sensor acess might be fine using synchronous PIO.
+
+But the queue will probably be very real, using message->queue, PIO,
+often DMA (especially if the root filesystem is in SPI flash), and
+execution contexts like IRQ handlers, tasklets, or workqueues (such
+as keventd). Your driver can be as fancy, or as simple, as you need.

+ Single-board computer made by Winsystems, Inc.
+
+ *Note*: This hardware watchdog is not probeable and thus there

+ timer at IO address 0x1ee and 0x1ef. It will write to both those
+ IO ports. Basically, the assumption is made that if you compile
+ this driver into your kernel and/or load it as a module, that you
+ know what you are doing and that you are in fact running on an
+ EPX-C3 board!

-AACRAID Driver for Linux (take two)
-
-Introduction
--------------------------
-The aacraid driver adds support for Adaptec (http://www.adaptec.com)
-RAID controllers. This is a major rewrite from the original
-Adaptec supplied driver. It has signficantly cleaned up both the code
-and the running binary size (the module is less than half the size of
-the original).

-People
--------------------------
-Alan Cox <alan@redhat.com>
-Christoph Hellwig <hch@infradead.org> (updates for new-style PCI probing and SCSI host registration,
- small cleanups/fixes)
-Matt Domsch <matt_domsch@dell.com> (revision ioctl, adapter messages)
-Deanna Bonds (non-DASD support, PAE fibs and 64 bit, added new adaptec controllers
- added new ioctls, changed scsi interface to use new error handler,
- increased the number of fibs and outstanding commands to a container)
-
- (fixed 64bit and 64G memory model, changed confusing naming convention
- where fibs that go to the hardware are consistently called hw_fibs and
- not just fibs like the name of the driver tracking structure)
-Mark Salyzyn <Mark_Salyzyn@adaptec.com> Fixed panic issues and added some new product ids for upcoming hbas. Performance tuning, card failover and bug mitigations.
-
-Original Driver
--------------------------
-Adaptec Unix OEM Product Group
-
-Mailing List
--------------------------
-linux-scsi@vger.kernel.org (Interested parties troll here)
-Also note this is very different to Brian's original driver
-so don't expect him to support it.
-Adaptec does support this driver. Contact either tech support or Mark Salyzyn.

+config SPI
+ bool "SPI support"
+ help
+ The "Serial Peripheral Interface" is a low level synchronous
+ protocol. Chips that support SPI can have data transfer rates
+ up to several tens of Mbit/sec. Chips are addressed with a
+ controller and a chipselect. Most SPI slaves don't support
+ dynamic device discovery; some are even write-only or read-only.
+
+ SPI is widely used by microcontollers to talk with sensors,
+ eeprom and flash memory, codecs and various other controller
+ chips, analog to digital (and d-to-a) converters, and more.
+ MMC and SD cards can be accessed using SPI protocol; and for
+ DataFlash cards used in MMC sockets, SPI must always be used.
+
+ SPI is one of a family of similar protocols using a four wire
+ interface (select, clock, data in, data out) including Microwire
+ (half duplex), SSP, SSI, and PSP. This driver framework should
+ work with most such devices and controllers.
+
+config SPI_DEBUG
+ boolean "Debug support for SPI drivers"

+ provides the clock and chipselect), you can enable that
+ controller and the protocol drivers for the SPI slave chips
+ that are connected.

+ help
+ With a few GPIO pins, your system can bitbang the SPI protocol.
+ Select this to get SPI support through I/O pins (GPIO, parallel
+ port, etc). Or, some systems' SPI master controller drivers use
+ this code to manage the per-word or per-transfer accesses to the
+ hardware shift registers.
+
+ This is library code, and is automatically selected by drivers that

+ modules that aren't part of this kernel tree.

- * LOADADDR( rn, name )
- * loads the address of 'name' into 'rn'
+ * LOAD_REG_IMMEDIATE(rn, expr)
+ * Loads the value of the constant expression 'expr' into register 'rn'

+ * to reference other data (i.e. on ppc64 when the TOC pointer is not
+ * valid).
*
- * LOADBASE( rn, name )
- * loads the address (possibly without the low 16 bits) of 'name' into 'rn'
- * suitable for base+disp addressing
+ * LOAD_REG_ADDR(rn, name)
+ * Loads the address of label 'name' into register 'rn'. Use this when
+ * you don't particularly need immediate instructions only, but you need
+ * the whole address in one register (e.g. it's a structure address and
+ * you want to access various offsets within it). On ppc32 this is
+ * identical to LOAD_REG_IMMEDIATE.
+ *
+ * LOAD_REG_ADDRBASE(rn, name)
+ * ADDROFF(name)
+ * LOAD_REG_ADDRBASE loads part of the address of label 'name' into
+ * register 'rn'. ADDROFF(name) returns the remainder of the address as
+ * a constant expression. ADDROFF(name) is a signed expression < 16 bits
+ * in size, so is suitable for use directly as an offset in load and store
+ * instructions. Use this when loading/storing a single word or less as:
+ * LOAD_REG_ADDRBASE(rX, name)
+ * ld rY,ADDROFF(name)(rX)

+ * SPI transfers always write the same number of bytes as they read.

+ * In some cases, they may also want to provide DMA addresses for

+ * (i) If the transfer isn't the last one in the message, this flag is
+ * used to make the chipselect briefly go inactive in the middle of the

+ * a chip command, letting a single spi_message perform all of group of
+ * chip transactions together.
+ *
+ * (ii) When the transfer is the last one in the message, the chip may
+ * stay selected until the next transfer. This is purely a performance
+ * hint; the controller driver may need to select a different device
+ * for the next message.

- `credit_cap'. The `peak rate' becomes the cost of passing the
- test, `cost'.
-
- `prev' tracks the last packet hit: you gain one credit per jiffy.
- If you get credit balance more than this, the extra credit is
- discarded. Every time the match passes, you lose `cost' credits;
- if you don't have that many, the test fails.
-
- See Alexey's formal explanation in net/sched/sch_tbf.c.
-
- To avoid underflow, we multiply by 128 (ie. you get 128 credits per
- jiffy). Hence a cost of 2^32-1, means one pass per 32768 seconds

+ * debug print buffer (DBG_OUTPUT), if it has been defined; this can be useful
+ * when there is only a single link in the system being debugged.

+/*
+ * The TIPC locking policy is designed to ensure a very fine locking
+ * granularity, permitting complete parallel access to individual
+ * port and node/link instances. The code consists of three major
+ * locking domains, each protected with their own disjunct set of locks.
+ *
+ * 1: The routing hierarchy.
+ * Comprises the structures 'zone', 'cluster', 'node', 'link'
+ * and 'bearer'. The whole hierarchy is protected by a big
+ * read/write lock, net_lock, to enssure that nothing is added
+ * or removed while code is accessing any of these structures.
+ * This layer must not be called from the two others while they
+ * hold any of their own locks.
+ * Neither must it itself do any upcalls to the other two before
+ * it has released net_lock and other protective locks.
+ *
+ * Within the net_lock domain there are two sub-domains;'node' and
+ * 'bearer', where local write operations are permitted,
+ * provided that those are protected by individual spin_locks
+ * per instance. Code holding net_lock(read) and a node spin_lock
+ * is permitted to poke around in both the node itself and its
+ * subordinate links. I.e, it can update link counters and queues,
+ * change link state, send protocol messages, and alter the
+ * "active_links" array in the node; but it can _not_ remove a link
+ * or a node from the overall structure.
+ * Correspondingly, individual bearers may change status within a
+ * net_lock(read), protected by an individual spin_lock ber bearer
+ * instance, but it needs net_lock(write) to remove/add any bearers.
+ *
+ *
+ * 2: The transport level of the protocol.
+ * This consists of the structures port, (and its user level
+ * representations, such as user_port and tipc_sock), reference and
+ * tipc_user (port.c, reg.c, socket.c).
+ *
+ * This layer has four different locks:
+ * - The tipc_port spin_lock. This is protecting each port instance
+ * from parallel data access and removal. Since we can not place
+ * this lock in the port itself, it has been placed in the
+ * corresponding reference table entry, which has the same life
+ * cycle as the module. This entry is difficult to access from
+ * outside the TIPC core, however, so a pointer to the lock has
+ * been added in the port instance, -to be used for unlocking
+ * only.
+ * - A read/write lock to protect the reference table itself (teg.c).
+ * (Nobody is using read-only access to this, so it can just as
+ * well be changed to a spin_lock)
+ * - A spin lock to protect the registry of kernel/driver users (reg.c)
+ * - A global spin_lock (port_lock), which only task is to ensure
+ * consistency where more than one port is involved in an operation,
+ * i.e., whe a port is part of a linked list of ports.
+ * There are two such lists; 'port_list', which is used for management,
+ * and 'wait_list', which is used to queue ports during congestion.
+ *
+ * 3: The name table (name_table.c, name_distr.c, subscription.c)
+ * - There is one big read/write-lock (nametbl_lock) protecting the
+ * overall name table structure. Nothing must be added/removed to
+ * this structure without holding write access to it.
+ * - There is one local spin_lock per sub_sequence, which can be seen
+ * as a sub-domain to the nametbl_lock domain. It is used only
+ * for translation operations, and is needed because a translation
+ * steps the root of the 'publication' linked list between each lookup.
+ * This is always used within the scope of a nametbl_lock(read).
+ * - A local spin_lock protecting the queue of subscriber events.
