+A generic digital 24-port PCI GPIO card can be built out of an ordinary
+Brooktree bt848, bt849, bt878 or bt879 based analog TV tuner card. The
+Brooktree chip is used in old analog Hauppauge WinTV PCI cards. You can easily

+
+The bt8xx chip does have 24 digital GPIO ports.
+These ports are accessible via 24 pins on the SMD chip package.

+
+==============================================
+== How to physically access the GPIO pins ==
+==============================================
+
+The are several ways to access these pins. One might unsolder the whole chip
+and put it on a custom PCI board, or one might only unsolder each individual
+GPIO pin and solder that to some tiny wire. As the chip package really is tiny
+there are some advanced soldering skills needed in any case.

+SH7760/SH7763 integrated LCDC Framebuffer driver
+================================================
+
+0. Overwiew
+-----------
+The SH7760/SH7763 have an integrated LCD Display controller (LCDC) which
+supports (in theory) resolutions ranging from 1x1 to 1024x1024,
+with color depths ranging from 1 to 16 bits, on STN, DSTN and TFT Panels.
+
+Caveats:
+* Framebuffer memory must be a large chunk allocated at the top
+ of Area3 (HW requirement). Because of this requirement you should NOT
+ make the driver a module since at runtime it may become impossible to
+ get a large enough contiguous chunk of memory.
+
+* The driver does not support changing resolution while loaded
+ (displays aren't hotpluggable anyway)
+
+* Heavy flickering may be observed
+ a) if you're using 15/16bit color modes at >= 640x480 px resolutions,
+ b) during PCMCIA (or any other slow bus) activity.
+
+* Rotation works only 90degress clockwise, and only if horizontal
+ resolution is <= 320 pixels.

+
+1. Platform setup
+-----------------
+SH7760:
+ Video data is fetched via the DMABRG DMA engine, so you have to
+ configure the SH DMAC for DMABRG mode (write 0x94808080 to the
+ DMARSRA register somewhere at boot).
+
+ PFC registers PCCR and PCDR must be set to peripheral mode.
+ (write zeros to both).
+
+The driver does NOT do the above for you since board setup is, well, job
+of the board setup code.
+
+2. Panel definitions
+--------------------
+The LCDC must explicitly be told about the type of LCD panel
+attached. Data must be wrapped in a "struct sh7760fb_platdata" and
+passed to the driver as platform_data.
+
+Suggest you take a closer look at the SH7760 Manual, Section 30.
+(http://documentation.renesas.com/eng/products/mpumcu/e602291_sh7760.pdf)

+Optimized MPEG Filesystem (OMFS)
+
+Overview
+========
+
+OMFS is a filesystem created by SonicBlue for use in the ReplayTV DVR
+and Rio Karma MP3 player. The filesystem is extent-based, utilizing
+block sizes from 2k to 8k, with hash-based directories. This
+filesystem driver may be used to read and write disks from these
+devices.
+
+Note, it is not recommended that this FS be used in place of a general
+filesystem for your own streaming media device. Native Linux filesystems
+will likely perform better.
+
+More information is available at:
+
+ http://linux-karma.sf.net/
+
+Various utilities, including mkomfs and omfsck, are included with
+omfsprogs, available at:
+
+ http://bobcopeland.com/karma/
+
+Instructions are included in its README.
+
+Options
+=======
+
+OMFS supports the following mount-time options:
+
+ uid=n - make all files owned by specified user
+ gid=n - make all files owned by specified group
+ umask=xxx - set permission umask to xxx
+ fmask=xxx - set umask to xxx for files
+ dmask=xxx - set umask to xxx for directories
+
+Disk format
+===========
+
+OMFS discriminates between "sysblocks" and normal data blocks. The sysblock
+group consists of super block information, file metadata, directory structures,
+and extents. Each sysblock has a header containing CRCs of the entire
+sysblock, and may be mirrored in successive blocks on the disk. A sysblock may
+have a smaller size than a data block, but since they are both addressed by the
+same 64-bit block number, any remaining space in the smaller sysblock is
+unused.
+
+Sysblock header information:
+
+struct omfs_header {
+ __be64 h_self; /* FS block where this is located */
+ __be32 h_body_size; /* size of useful data after header */
+ __be16 h_crc; /* crc-ccitt of body_size bytes */
+ char h_fill1[2];
+ u8 h_version; /* version, always 1 */
+ char h_type; /* OMFS_INODE_X */
+ u8 h_magic; /* OMFS_IMAGIC */
+ u8 h_check_xor; /* XOR of header bytes before this */
+ __be32 h_fill2;
+};
+
+Files and directories are both represented by omfs_inode:
+
+struct omfs_inode {
+ struct omfs_header i_head; /* header */
+ __be64 i_parent; /* parent containing this inode */
+ __be64 i_sibling; /* next inode in hash bucket */
+ __be64 i_ctime; /* ctime, in milliseconds */
+ char i_fill1[35];
+ char i_type; /* OMFS_[DIR,FILE] */
+ __be32 i_fill2;
+ char i_fill3[64];
+ char i_name[OMFS_NAMELEN]; /* filename */
+ __be64 i_size; /* size of file, in bytes */
+};
+
+Directories in OMFS are implemented as a large hash table. Filenames are
+hashed then prepended into the bucket list beginning at OMFS_DIR_START.
+Lookup requires hashing the filename, then seeking across i_sibling pointers
+until a match is found on i_name. Empty buckets are represented by block
+pointers with all-1s (~0).
+
+A file is an omfs_inode structure followed by an extent table beginning at
+OMFS_EXTENT_START:
+
+struct omfs_extent_entry {
+ __be64 e_cluster; /* start location of a set of blocks */
+ __be64 e_blocks; /* number of blocks after e_cluster */
+};
+
+struct omfs_extent {
+ __be64 e_next; /* next extent table location */
+ __be32 e_extent_count; /* total # extents in this table */
+ __be32 e_fill;
+ struct omfs_extent_entry e_entry; /* start of extent entries */
+};
+
+Each extent holds the block offset followed by number of blocks allocated to
+the extent. The final extent in each table is a terminator with e_cluster
+being ~0 and e_blocks being ones'-complement of the total number of blocks
+in the table.
+
+If this table overflows, a continuation inode is written and pointed to by
+e_next. These have a header but lack the rest of the inode structure.

+once all the necessary resources are available, and remove them later when

+
+
+Sysfs Interface for Userspace (OPTIONAL)
+========================================
+Platforms which use the "gpiolib" implementors framework may choose to
+configure a sysfs user interface to GPIOs. This is different from the
+debugfs interface, since it provides control over GPIO direction and
+value instead of just showing a gpio state summary. Plus, it could be
+present on production systems without debugging support.
+
+Given approprate hardware documentation for the system, userspace could
+know for example that GPIO #23 controls the write protect line used to
+protect boot loader segments in flash memory. System upgrade procedures
+may need to temporarily remove that protection, first importing a GPIO,
+then changing its output state, then updating the code before re-enabling
+the write protection. In normal use, GPIO #23 would never be touched,
+and the kernel would have no need to know about it.
+
+Again depending on appropriate hardware documentation, on some systems
+userspace GPIO can be used to determine system configuration data that
+standard kernels won't know about. And for some tasks, simple userspace
+GPIO drivers could be all that the system really needs.
+
+Note that standard kernel drivers exist for common "LEDs and Buttons"
+GPIO tasks: "leds-gpio" and "gpio_keys", respectively. Use those
+instead of talking directly to the GPIOs; they integrate with kernel
+frameworks better than your userspace code could.
+
+
+Paths in Sysfs
+--------------
+There are three kinds of entry in /sys/class/gpio:
+
+ - Control interfaces used to get userspace control over GPIOs;
+
+ - GPIOs themselves; and
+
+ - GPIO controllers ("gpio_chip" instances).
+
+That's in addition to standard files including the "device" symlink.
+
+The control interfaces are write-only:
+
+ /sys/class/gpio/
+
+ "export" ... Userspace may ask the kernel to export control of
+ a GPIO to userspace by writing its number to this file.
+
+ Example: "echo 19 > export" will create a "gpio19" node
+ for GPIO #19, if that's not requested by kernel code.
+
+ "unexport" ... Reverses the effect of exporting to userspace.
+
+ Example: "echo 19 > unexport" will remove a "gpio19"
+ node exported using the "export" file.
+
+GPIO signals have paths like /sys/class/gpio/gpio42/ (for GPIO #42)
+and have the following read/write attributes:
+
+ /sys/class/gpio/gpioN/
+
+ "direction" ... reads as either "in" or "out". This value may
+ normally be written. Writing as "out" defaults to
+ initializing the value as low. To ensure glitch free
+ operation, values "low" and "high" may be written to
+ configure the GPIO as an output with that initial value.
+
+ Note that this attribute *will not exist* if the kernel
+ doesn't support changing the direction of a GPIO, or
+ it was exported by kernel code that didn't explicitly
+ allow userspace to reconfigure this GPIO's direction.
+
+ "value" ... reads as either 0 (low) or 1 (high). If the GPIO
+ is configured as an output, this value may be written;
+ any nonzero value is treated as high.
+
+GPIO controllers have paths like /sys/class/gpio/chipchip42/ (for the
+controller implementing GPIOs starting at #42) and have the following
+read-only attributes:
+
+ /sys/class/gpio/gpiochipN/
+
+ "base" ... same as N, the first GPIO managed by this chip
+
+ "label" ... provided for diagnostics (not always unique)
+
+ "ngpio" ... how many GPIOs this manges (N to N + ngpio - 1)
+
+Board documentation should in most cases cover what GPIOs are used for
+what purposes. However, those numbers are not always stable; GPIOs on
+a daughtercard might be different depending on the base board being used,
+or other cards in the stack. In such cases, you may need to use the
+gpiochip nodes (possibly in conjunction with schematics) to determine
+the correct GPIO number to use for a given signal.
+
+
+Exporting from Kernel code
+--------------------------
+Kernel code can explicitly manage exports of GPIOs which have already been
+requested using gpio_request():
+
+ /* export the GPIO to userspace */
+ int gpio_export(unsigned gpio, bool direction_may_change);
+
+ /* reverse gpio_export() */
+ void gpio_unexport();
+
+After a kernel driver requests a GPIO, it may only be made available in
+the sysfs interface by gpio_export(). The driver can control whether the
+signal direction may change. This helps drivers prevent userspace code
+from accidentally clobbering important system state.
+
+This explicit exporting can help with debugging (by making some kinds
+of experiments easier), or can provide an always-there interface that's
+suitable for documenting as part of a board support package.

-your driver into the driver model, and use its suspend()/resume()
-callbacks to do this kind of stuff.
-
-If you are writing a new driver or maintaining an old driver, it
-should include power management support. Without power management
-support, a single driver may prevent a system with power management
-capabilities from ever being able to suspend (safely).
-
-Overview:
-1) Register each instance of a device with "pm_register"
-2) Call "pm_access" before accessing the hardware.
- (this will ensure that the hardware is awake and ready)
-3) Your "pm_callback" is called before going into a
- suspend state (ACPI D1-D3) or after resuming (ACPI D0)
- from a suspend.
-4) Call "pm_dev_idle" when the device is not being used
- (optional but will improve device idle detection)
-5) When unloaded, unregister the device with "pm_unregister"

-Driver Details
---------------
-This is just a quick Q&A as a stopgap until a real driver writers'
-power management guide is available.
-
-Q: When is a device suspended?
-
-Devices can be suspended based on direct user request (eg. laptop lid
-closes), system power policy (eg. sleep after 30 minutes of console
-inactivity), or device power policy (eg. power down device after 5
-minutes of inactivity)
-
-Q: Must a driver honor a suspend request?
-
-No, a driver can return -EBUSY from a suspend request and this
-will stop the system from suspending. When a suspend request
-fails, all suspended devices are resumed and the system continues
-to run. Suspend can be retried at a later time.
-
-Q: Can the driver block suspend/resume requests?
-
-Yes, a driver can delay its return from a suspend or resume
-request until the device is ready to handle requests. It
-is advantageous to return as quickly as possible from a
-request as suspend/resume are done serially.
-
-Q: What context is a suspend/resume initiated from?
-
-A suspend or resume is initiated from a kernel thread context.
-It is safe to block, allocate memory, initiate requests
-or anything else you can do within the kernel.
-
-Q: Will requests continue to arrive after a suspend?
-
-Possibly. It is the driver's responsibility to queue(*),
-fail, or drop any requests that arrive after returning
-success to a suspend request. It is important that the
-driver not access its device until after it receives
-a resume request as the device's bus may no longer
-be active.
-
-(*) If a driver queues requests for processing after
- resume be aware that the device, network, etc.
- might be in a different state than at suspend time.
- It's probably better to drop requests unless
- the driver is a storage device.
-
-Q: Do I have to manage bus-specific power management registers
-
-No. It is the responsibility of the bus driver to manage
-PCI, USB, etc. power management registers. The bus driver
-or the power management subsystem will also enable any
-wake-on functionality that the device has.
-
-Q: So, really, what do I need to do to support suspend/resume?
-
-You need to save any device context that would
-be lost if the device was powered off and then restore
-it at resume time. When ACPI is active, there are
-three levels of device suspend states; D1, D2, and D3.
-(The suspend state is passed as the "data" argument
-to the device callback.) With D3, the device is powered
-off and loses all context, D1 and D2 are shallower power
-states and require less device context to be saved. To
-play it safe, just save everything at suspend and restore
-everything at resume.
-
-Q: Where do I store device context for suspend?
-
-Anywhere in memory, kmalloc a buffer or store it
-in the device descriptor. You are guaranteed that the
-contents of memory will be restored and accessible
-before resume, even when the system suspends to disk.
-
-Q: What do I need to do for ACPI vs. APM vs. etc?
-
-Drivers need not be aware of the specific power management
-technology that is active. They just need to be aware
-of when the overlying power management system requests
-that they suspend or resume.
-
-Q: What about device dependencies?
-
-When a driver registers a device, the power management
-subsystem uses the information provided to build a
-tree of device dependencies (eg. USB device X is on
-USB controller Y which is on PCI bus Z) When power
-management wants to suspend a device, it first sends
-a suspend request to its driver, then the bus driver,
-and so on up to the system bus. Device resumes
-proceed in the opposite direction.
-
-Q: Who do I contact for additional information about
- enabling power management for my specific driver/device?
-
-ACPI Development mailing list: linux-acpi@vger.kernel.org
-
-System Interface -- OBSOLETE, DO NOT USE!
-----------------*************************
-If you are providing new power management support to Linux (ie.
-adding support for something like APM or ACPI), you should
-communicate with drivers through the existing generic power
-management interface.
-

+
+ The SPI master node requires the following properties:
+ - #address-cells - number of cells required to define a chip select

+ - #size-cells - should be zero.
+ - compatible - name of SPI bus controller following generic names

+ No other properties are required in the SPI bus node. It is assumed

+ However, the binding does not attempt to define the specific method for

+ flexible and non-standardized, it is left out of this binding with the
+ assumption that board specific platform code will be used to manage
+ chip selects. Individual drivers can define additional properties to
+ support describing the chip select layout.

+Alignment vs. Networking
+========================
+
+On architectures that require aligned loads, networking requires that the IP
+header is aligned on a four-byte boundary to optimise the IP stack. For
+regular ethernet hardware, the constant NET_IP_ALIGN is used. On most
+architectures this constant has the value 2 because the normal ethernet
+header is 14 bytes long, so in order to get proper alignment one needs to
+DMA to an address which can be expressed as 4*n + 2. One notable exception
+here is powerpc which defines NET_IP_ALIGN to 0 because DMA to unaligned
+addresses can be very expensive and dwarf the cost of unaligned loads.
+
+For some ethernet hardware that cannot DMA to unaligned addresses like
+4*n+2 or non-ethernet hardware, this can be a problem, and it is then
+required to copy the incoming frame into an aligned buffer. Because this is

sufficiently, or the surplus huge pages go out of use and are freed.
+With support for multiple hugepage pools at run-time available, much of
+the hugepage userspace interface has been duplicated in sysfs. The above
+information applies to the default hugepage size (which will be
+controlled by the proc interfaces for backwards compatibility). The root
+hugepage control directory is
+
+ /sys/kernel/mm/hugepages
+
+For each hugepage size supported by the running kernel, a subdirectory
+will exist, of the form

+Inside each of these directories, the same set of files will exist:

+ surplus_hugepages

If the user applications are going to request hugepages using mmap system
call, then it is required that system administrator mount a file system of
type hugetlbfs:

- The maximum number of Unix98 PTYs that can be used at any one time.
- The default is 256, and should be enough for desktop systems. Server

-This port to the NEC V850E processor supports the following platforms:
-
- "sim"
- The gdb v850e simulator (CONFIG_V850E_SIM).
-
- "rte-ma1-cb"
- The Midas labs RTE-V850E/MA1-CB and RTE-V850E/NB85E-CB evaluation
- boards (CONFIG_RTE_CB_MA1 and CONFIG_RTE_CB_NB85E). This support
- has only been tested when running with the Multi-debugger monitor
- ROM (for the Green Hills Multi debugger). The optional NEC
- Solution Gear RTE-MOTHER-A motherboard is also supported, which
- allows PCI boards to be used (CONFIG_RTE_MB_A_PCI).
-
- "rte-me2-cb"
- The Midas labs RTE-V850E/ME2-CB evaluation board (CONFIG_RTE_CB_ME2).
- This has only been tested using a kernel downloaded via an ICE
- connection using the Multi debugger. Support for the RTE-MOTHER-A is
- present, but hasn't been tested (unlike the other Midas labs cpu
- boards, the RTE-V850E/ME2-CB includes an ethernet adaptor).
-
- "as85ep1"
- The NEC AS85EP1 V850E evaluation chip/board (CONFIG_V850E_AS85EP1).
-
- "anna"
- The NEC `Anna' (board/chip) implementation of the V850E2 processor
- (CONFIG_V850E2_ANNA).
-
- "sim85e2c", "sim85e2s"
- The sim85e2c and sim85e2s simulators, which are verilog simulations
- of the V850E2 NA85E2C/NA85E2S cpu cores (CONFIG_V850E2_SIM85E2C and
- CONFIG_V850E2_SIM85E2S).
-
- "fpga85e2c"
- A FPGA implementation of the V850E2 NA85E2C cpu core
- (CONFIG_V850E2_FPGA85E2C).
-
-To get a default kernel configuration for a particular platform, you can
-use a <platform>_defconfig make target (e.g., "make rte-me2-cb_defconfig");
-to see which default configurations are possible, look in the directory
-"arch/v850/configs".
-
-Porting to anything with a V850E/MA1 or MA2 processor should be simple.
-See the file <asm-v850/machdep.h> and the files it includes for an example of
-how to add platform/chip-specific support.

+ * the detailed organization of these ports.

+ * HFC-8S (8 S/T interfaces on one chip)

+ * Or use the following combinations:
+ * Bit 0-7 = 0x00001 = HFC-E1 (1 port)
+ * or Bit 0-7 = 0x00004 = HFC-4S (4 ports)
+ * or Bit 0-7 = 0x00008 = HFC-8S (8 ports)
+ * Bit 8 = 0x00100 = uLaw (instead of aLaw)
+ * Bit 9 = 0x00200 = Disable DTMF detect on all B-channels via hardware
+ * Bit 10 = spare
+ * Bit 11 = 0x00800 = Force PCM bus into slave mode. (otherwhise auto)
+ * or Bit 12 = 0x01000 = Force PCM bus into master mode. (otherwhise auto)
+ * Bit 13 = spare
+ * Bit 14 = 0x04000 = Use external ram (128K)
+ * Bit 15 = 0x08000 = Use external ram (512K)
+ * Bit 16 = 0x10000 = Use 64 timeslots instead of 32
+ * or Bit 17 = 0x20000 = Use 128 timeslots instead of anything else
+ * Bit 18 = spare
+ * Bit 19 = 0x80000 = Send the Watchdog a Signal (Dual E1 with Watchdog)
+ * (all other bits are reserved and shall be 0)
+ * example: 0x20204 one HFC-4S with dtmf detection and 128 timeslots on PCM
+ * bus (PCM master)
+ *
+ * port: (optional or required for all ports on all installed cards)
+ * HFC-4S/HFC-8S only bits:
+ * Bit 0 = 0x001 = Use master clock for this S/T interface
+ * (ony once per chip).
+ * Bit 1 = 0x002 = transmitter line setup (non capacitive mode)
+ * Don't use this unless you know what you are doing!
+ * Bit 2 = 0x004 = Disable E-channel. (No E-channel processing)
+ * example: 0x0001,0x0000,0x0000,0x0000 one HFC-4S with master clock
+ * received from port 1
+ *
+ * HFC-E1 only bits:
+ * Bit 0 = 0x0001 = interface: 0=copper, 1=optical
+ * Bit 1 = 0x0002 = reserved (later for 32 B-channels transparent mode)
+ * Bit 2 = 0x0004 = Report LOS
+ * Bit 3 = 0x0008 = Report AIS
+ * Bit 4 = 0x0010 = Report SLIP
+ * Bit 5 = 0x0020 = Report RDI
+ * Bit 8 = 0x0100 = Turn off CRC-4 Multiframe Mode, use double frame
+ * mode instead.
+ * Bit 9 = 0x0200 = Force get clock from interface, even in NT mode.
+ * or Bit 10 = 0x0400 = Force put clock to interface, even in TE mode.
+ * Bit 11 = 0x0800 = Use direct RX clock for PCM sync rather than PLL.
+ * (E1 only)
+ * Bit 12-13 = 0xX000 = elastic jitter buffer (1-3), Set both bits to 0
+ * for default.
+ * (all other bits are reserved and shall be 0)
+ *
+ * debug:
+ * NOTE: only one debug value must be given for all cards
+ * enable debugging (see hfc_multi.h for debug options)
+ *
+ * poll:
+ * NOTE: only one poll value must be given for all cards
+ * Give the number of samples for each fifo process.
+ * By default 128 is used. Decrease to reduce delay, increase to
+ * reduce cpu load. If unsure, don't mess with it!
+ * Valid is 8, 16, 32, 64, 128, 256.
+ *
+ * pcm:
+ * NOTE: only one pcm value must be given for every card.
+ * The PCM bus id tells the mISDNdsp module about the connected PCM bus.
+ * By default (0), the PCM bus id is 100 for the card that is PCM master.
+ * If multiple cards are PCM master (because they are not interconnected),
+ * each card with PCM master will have increasing PCM id.
+ * All PCM busses with the same ID are expected to be connected and have
+ * common time slots slots.
+ * Only one chip of the PCM bus must be master, the others slave.
+ * -1 means no support of PCM bus not even.
+ * Omit this value, if all cards are interconnected or none is connected.
+ * If unsure, don't give this parameter.
+ *
+ * dslot:
+ * NOTE: only one poll value must be given for every card.
+ * Also this value must be given for non-E1 cards. If omitted, the E1
+ * card has D-channel on time slot 16, which is default.
+ * If 1..15 or 17..31, an alternate time slot is used for D-channel.
+ * In this case, the application must be able to handle this.
+ * If -1 is given, the D-channel is disabled and all 31 slots can be used
+ * for B-channel. (only for specific applications)
+ * If you don't know how to use it, you don't need it!
+ *
+ * iomode:
+ * NOTE: only one mode value must be given for every card.
+ * -> See hfc_multi.h for HFC_IO_MODE_* values
+ * By default, the IO mode is pci memory IO (MEMIO).
+ * Some cards requre specific IO mode, so it cannot be changed.
+ * It may be usefull to set IO mode to register io (REGIO) to solve
+ * PCI bridge problems.
+ * If unsure, don't give this parameter.
+ *
+ * clockdelay_nt:
+ * NOTE: only one clockdelay_nt value must be given once for all cards.
+ * Give the value of the clock control register (A_ST_CLK_DLY)
+ * of the S/T interfaces in NT mode.
+ * This register is needed for the TBR3 certification, so don't change it.
+ *
+ * clockdelay_te:
+ * NOTE: only one clockdelay_te value must be given once
+ * Give the value of the clock control register (A_ST_CLK_DLY)
+ * of the S/T interfaces in TE mode.
+ * This register is needed for the TBR3 certification, so don't change it.

+ * how to encode a sample stream to 64-bit blocks that will be encryped
+ *
+ * first of all, data is collected until a block of 9 samples are received.
+ * of course, a packet may have much more than 9 sample, but is may have
+ * not excacly the multiple of 9 samples. if there is a rest, the next
+ * received data will complete the block.
+ *
+ * the block is then converted to 9 uLAW samples without the least sigificant
+ * bit. the result is a 7-bit encoded sample.
+ *
+ * the samples will be reoganised to form 8 bytes of data:
+ * (5(6) means: encoded sample no. 5, bit 6)
+ *
+ * 0(6) 0(5) 0(4) 0(3) 0(2) 0(1) 0(0) 1(6)
+ * 1(5) 1(4) 1(3) 1(2) 1(1) 1(0) 2(6) 2(5)
+ * 2(4) 2(3) 2(2) 2(1) 2(0) 3(6) 3(5) 3(4)
+ * 3(3) 3(2) 3(1) 3(0) 4(6) 4(5) 4(4) 4(3)
+ * 4(2) 4(1) 4(0) 5(6) 5(5) 5(4) 5(3) 5(2)
+ * 5(1) 5(0) 6(6) 6(5) 6(4) 6(3) 6(2) 6(1)
+ * 6(0) 7(6) 7(5) 7(4) 7(3) 7(2) 7(1) 7(0)
+ * 8(6) 8(5) 8(4) 8(3) 8(2) 8(1) 8(0)
+ *
+ * the missing bit 0 of the last byte is filled with some
+ * random noise, to fill all 8 bytes.
+ *
+ * the 8 bytes will be encrypted using blowfish.
+ *
+ * the result will be converted into 9 bytes. the bit 7 is used for
+ * checksumme (CS) for sync (0, 1) and for the last bit:
+ * (5(6) means: crypted byte 5, bit 6)
+ *
+ * 1 0(7) 0(6) 0(5) 0(4) 0(3) 0(2) 0(1)
+ * 0 0(0) 1(7) 1(6) 1(5) 1(4) 1(3) 1(2)
+ * 0 1(1) 1(0) 2(7) 2(6) 2(5) 2(4) 2(3)
+ * 0 2(2) 2(1) 2(0) 3(7) 3(6) 3(5) 3(4)
+ * 0 3(3) 3(2) 3(1) 3(0) 4(7) 4(6) 4(5)
+ * CS 4(4) 4(3) 4(2) 4(1) 4(0) 5(7) 5(6)
+ * CS 5(5) 5(4) 5(3) 5(2) 5(1) 5(0) 6(7)
+ * CS 6(6) 6(5) 6(4) 6(3) 6(2) 6(1) 6(0)
+ * 7(0) 7(6) 7(5) 7(4) 7(3) 7(2) 7(1) 7(0)
+ *
+ * the checksum is used to detect transmission errors and frame drops.
+ *
+ * synchronisation of received block is done by shifting the upper bit of each
+ * byte (bit 7) to a shift register. if the rigister has the first five bits
+ * (10000), this is used to find the sync. only if sync has been found, the
+ * current block of 9 received bytes are decrypted. before that the check
+ * sum is calculated. if it is incorrect the block is dropped.
+ * this will avoid loud noise due to corrupt encrypted data.
+ *
+ * if the last block is corrupt, the current decoded block is repeated
+ * until a valid block has been received.

+
+/*
+ * HOW THE CMX WORKS:
+ *
+ * There are 3 types of interaction: One member is alone, in this case only
+ * data flow from upper to lower layer is done.
+ * Two members will also exchange their data so they are crossconnected.
+ * Three or more members will be added in a conference and will hear each
+ * other but will not receive their own speech (echo) if not enabled.
+ *
+ * Features of CMX are:
+ * - Crossconnecting or even conference, if more than two members are together.
+ * - Force mixing of transmit data with other crossconnect/conference members.
+ * - Echo generation to benchmark the delay of audio processing.
+ * - Use hardware to minimize cpu load, disable FIFO load and minimize delay.
+ * - Dejittering and clock generation.
+ *
+ * There are 2 buffers:
+ *
+ *
+ * RX-Buffer
+ * R W
+ * | |
+ * ----------------+-------------+-------------------
+ *
+ * The rx-buffer is a ring buffer used to store the received data for each
+ * individual member. This is only the case if data needs to be dejittered
+ * or in case of a conference where different clocks require reclocking.
+ * The transmit-clock (R) will read the buffer.
+ * If the clock overruns the write-pointer, we will have a buffer underrun.
+ * If the write pointer always has a certain distance from the transmit-
+ * clock, we will have a delay. The delay will dynamically be increased and
+ * reduced.
+ *
+ *
+ * TX-Buffer
+ * R W
+ * | |
+ * -----------------+--------+-----------------------
+ *
+ * The tx-buffer is a ring buffer to queue the transmit data from user space
+ * until it will be mixed or sent. There are two pointers, R and W. If the write
+ * pointer W would reach or overrun R, the buffer would overrun. In this case
+ * (some) data is dropped so that it will not overrun.
+ * Additionally a dynamic dejittering can be enabled. this allows data from
+ * user space that have jitter and different clock source.
+ *
+ *
+ * Clock:
+ *
+ * A Clock is not required, if the data source has exactly one clock. In this
+ * case the data source is forwarded to the destination.
+ *
+ * A Clock is required, because the data source
+ * - has multiple clocks.
+ * - has no usable clock due to jitter or packet loss (VoIP).
+ * In this case the system's clock is used. The clock resolution depends on
+ * the jiffie resolution.
+ *
+ * If a member joins a conference:
+ *
+ * - If a member joins, its rx_buff is set to silence and change read pointer
+ * to transmit clock.
+ *
+ * The procedure of received data from card is explained in cmx_receive.
+ * The procedure of received data from user space is explained in cmx_transmit.
+ * The procedure of transmit data to card is cmx_send.
+ *
+ *
+ * Interaction with other features:
+ *
+ * DTMF:
+ * DTMF decoding is done before the data is crossconnected.
+ *
+ * Volume change:
+ * Changing rx-volume is done before the data is crossconnected. The tx-volume
+ * must be changed whenever data is transmitted to the card by the cmx.
+ *
+ * Tones:
+ * If a tone is enabled, it will be processed whenever data is transmitted to
+ * the card. It will replace the tx-data from the user space.
+ * If tones are generated by hardware, this conference member is removed for
+ * this time.
+ *
+ * Disable rx-data:
+ * If cmx is realized in hardware, rx data will be disabled if requested by
+ * the upper layer. If dtmf decoding is done by software and enabled, rx data
+ * will not be diabled but blocked to the upper layer.
+ *
+ * HFC conference engine:
+ * If it is possible to realize all features using hardware, hardware will be
+ * used if not forbidden by control command. Disabling rx-data provides
+ * absolutely traffic free audio processing. (except for the quick 1-frame
+ * upload of a tone loop, only once for a new tone)

+/* STRUCTURE:
+ *
+ * The dsp module provides layer 2 for b-channels (64kbit). It provides
+ * transparent audio forwarding with special digital signal processing:
+ *
+ * - (1) generation of tones
+ * - (2) detection of dtmf tones
+ * - (3) crossconnecting and conferences (clocking)
+ * - (4) echo generation for delay test
+ * - (5) volume control
+ * - (6) disable receive data
+ * - (7) pipeline
+ * - (8) encryption/decryption
+ *
+ * Look:

+ * ------card layer------
+ * TX RX
+ *
+ * Above you can see the logical data flow. If software is used to do the
+ * process, it is actually the real data flow. If hardware is used, data
+ * may not flow, but hardware commands to the card, to provide the data flow
+ * as shown.
+ *
+ * NOTE: The channel must be activated in order to make dsp work, even if
+ * no data flow to the upper layer is intended. Activation can be done
+ * after and before controlling the setting using PH_CONTROL requests.
+ *
+ * DTMF: Will be detected by hardware if possible. It is done before CMX
+ * processing.
+ *
+ * Tones: Will be generated via software if endless looped audio fifos are
+ * not supported by hardware. Tones will override all data from CMX.
+ * It is not required to join a conference to use tones at any time.
+ *
+ * CMX: Is transparent when not used. When it is used, it will do
+ * crossconnections and conferences via software if not possible through
+ * hardware. If hardware capability is available, hardware is used.
+ *
+ * Echo: Is generated by CMX and is used to check performane of hard and
+ * software CMX.
+ *
+ * The CMX has special functions for conferences with one, two and more
+ * members. It will allow different types of data flow. Receive and transmit
+ * data to/form upper layer may be swithed on/off individually without loosing
+ * features of CMX, Tones and DTMF.
+ *
+ * Echo Cancellation: Sometimes we like to cancel echo from the interface.
+ * Note that a VoIP call may not have echo caused by the IP phone. The echo
+ * is generated by the telephone line connected to it. Because the delay
+ * is high, it becomes an echo. RESULT: Echo Cachelation is required if
+ * both echo AND delay is applied to an interface.
+ * Remember that software CMX always generates a more or less delay.
+ *
+ * If all used features can be realized in hardware, and if transmit and/or
+ * receive data ist disabled, the card may not send/receive any data at all.
+ * Not receiving is usefull if only announcements are played. Not sending is
+ * usefull if an answering machine records audio. Not sending and receiving is
+ * usefull during most states of the call. If supported by hardware, tones
+ * will be played without cpu load. Small PBXs and NT-Mode applications will
+ * not need expensive hardware when processing calls.
+ *
+ *
+ * LOCKING:
+ *
+ * When data is received from upper or lower layer (card), the complete dsp
+ * module is locked by a global lock. This lock MUST lock irq, because it
+ * must lock timer events by DSP poll timer.
+ * When data is ready to be transmitted down, the data is queued and sent
+ * outside lock and timer event.
+ * PH_CONTROL must not change any settings, join or split conference members
+ * during process of data.
+ *
+ * HDLC:
+ *
+ * It works quite the same as transparent, except that HDLC data is forwarded
+ * to all other conference members if no hardware bridging is possible.
+ * Send data will be writte to sendq. Sendq will be sent if confirm is received.
+ * Conference cannot join, if one member is not hdlc.

+
+How the codec works:
+--------------------
+
+The volume is increased to increase the dynamic range of the audio signal.
+Each sample is converted to a-LAW with only 16 steps of level resolution.
+A pair of two samples are stored in one byte.
+
+The first byte is stored in the upper bits, the second byte is stored in the
+lower bits.
+
+To speed up compression and decompression, two lookup tables are formed:
+
+- 16 bits index for two samples (law encoded) with 8 bit compressed result.
+- 8 bits index for one compressed data with 16 bits decompressed result.
+
+NOTE: The bytes are handled as they are law-encoded.

+ Value 0 = transparent (default)
+ Value 1 = transfer ALAW
+ Value 2 = transfer ULAW
+ Value 3 = transfer generic 4 bit compression.

+ * ulaw:
+ 0 = we use a-Law (default)
+ 1 = we use u-Law
+
+ * limit:
+ limitation of B-channels to control bandwidth (1...126)
+ BRI: 1 or 2
+ PRI: 1-30, 31-126 (126, because dchannel ist not counted here)
+ Also limited ressources are used for stack, resulting in less channels.
+ It is possible to have more channels than 30 in PRI mode, this must
+ be supported by the application.
+
+ * ip:
+ byte representation of remote ip address (127.0.0.1 -> 127,0,0,1)
+ If not given or four 0, no remote address is set.
+ For multiple interfaces, concat ip addresses. (127,0,0,1,127,0,0,1)
+
+ * port:

+ If not given or 0, port 931 is used for fist instance, 932 for next...
+ For multiple interfaces, different ports must be given.
+
+ * remoteport:
+ port number (remote interface)
+ If not given or 0, remote port equals local port
+ For multiple interfaces on equal sites, different ports must be given.
+
+ * ondemand:
+ 0 = fixed (always transmit packets, even when remote side timed out)
+ 1 = on demand (only transmit packets, when remote side is detected)
+ the default is 0
+ NOTE: ID must also be set for on demand.
+
+ * id:
+ optional value to identify frames. This value must be equal on both

+
+* Only included in some cases.
+
+- Ver = Version
+If version is missmatch, the frame must be ignored.
+
+- T = Type of interface
+Must be 0 for S0 or 1 for E1.
+
+- I = Id present
+If bit is set, four ID bytes are included in frame.
+
+- ID = Connection ID
+Additional ID to prevent Denial of Service attacs. Also it prevents hijacking
+connections with dynamic IP. The ID should be random and must not be 0.
+
+- Coding = Type of codec
+Must be 0 for no transcoding. Also for D-channel and other HDLC frames.
+ 1 and 2 are reserved for explicitly use of a-LAW or u-LAW codec.
+ 3 is used for generic table compressor.
+
+- M = More channels to come. If this flag is 1, the following byte contains
+the length of the channel data. After the data block, the next channel will
+be defined. The flag for the last channel block (or if only one channel is
+transmitted), must be 0 and no length is given.
+
+- Channel = Channel number
+0 reserved
+1-3 channel data for S0 (3 is D-channel)
+1-31 channel data for E1 (16 is D-channel)
+32-127 channel data for extended E1 (16 is D-channel)
+
+- The length is used if the M-flag is 1. It is used to find the next channel
+inside frame.
+NOTE: A value of 0 equals 256 bytes of data.
+ -> For larger data blocks, a single frame must be used.
+ -> For larger streams, a single frame or multiple blocks with same channel ID
+ must be used.
+
+- Time Base = Timestamp of first sample in frame
+The "Time Base" is used to rearange packets and to detect packet loss.
+The 16 bits are sent in network order (MSB first) and count 1/8000 th of a
+second. This causes a wrap arround each 8,192 seconds. There is no requirement
+for the initial "Time Base", but 0 should be used for the first packet.
+In case of HDLC data, this timestamp counts the packet or byte number.
+
+
+Two Timers:
+
+After initialisation, a timer of 15 seconds is started. Whenever a packet is
+transmitted, the timer is reset to 15 seconds again. If the timer expires, an
+empty packet is transmitted. This keep the connection alive.
+
+When a valid packet is received, a timer 65 seconds is started. The interface
+become ACTIVE. If the timer expires, the interface becomes INACTIVE.
+
+
+Dynamic IP handling:
+
+To allow dynamic IP, the ID must be non 0. In this case, any packet with the
+correct port number and ID will be accepted. If the remote side changes its IP
+the new IP is used for all transmitted packets until it changes again.
+
+
+On Demand:
+
+If the ondemand parameter is given, the remote IP is set to 0 on timeout.
+This will stop keepalive traffic to remote. If the remote is online again,
+traffic will continue to the remote address. This is usefull for road warriors.
+This feature only works with ID set, otherwhise it is highly unsecure.
+
+
+Socket and Thread
+-----------------
+
+The complete socket opening and closing is done by a thread.
+When the thread opened a socket, the hc->socket descriptor is set. Whenever a
+packet shall be sent to the socket, the hc->socket must be checked wheter not
+NULL. To prevent change in socket descriptor, the hc->socket_lock must be used.
+To change the socket, a recall of l1oip_socket_open() will safely kill the
+socket process and create a new one.

+ * natural on DS1305.
+ *
+ * - Fourth, there's also ALM1, and a second interrupt signal:
+ * + On DS1305 ALM1 uses nINT1 (when INTCN=1) else nINT0;
+ * + On DS1306 ALM1 only uses INT1 (an active high pulse)
+ * and it won't work when VCC1 is active.

+ * So to be most general, we should probably set both alarms to the
+ * same value, letting ALM1 be the wakeup event source on DS1306
+ * and handling several wiring options on DS1305.

- This is a virtual file system providing information about the status
- of the system. "Virtual" means that it doesn't take up any space on
- your hard disk: the files are created on the fly by the kernel when
- you try to access them. Also, you cannot read the files with older
- version of the program less: you need to use more or cat.
-
- It's totally cool; for example, "cat /proc/interrupts" gives
- information about what the different IRQs are used for at the moment
- (there is a small number of Interrupt ReQuest lines in your computer
- that are used by the attached devices to gain the CPU's attention --
- often a source of trouble if two devices are mistakenly configured
- to use the same IRQ). The program procinfo to display some
- information about your system gathered from the /proc file system.
-
- Before you can use the /proc file system, it has to be mounted,
- meaning it has to be given a location in the directory hierarchy.
- That location should be /proc. A command such as "mount -t proc proc
- /proc" or the equivalent line in /etc/fstab does the job.
-
- The /proc file system is explained in the file
- <file:Documentation/filesystems/proc.txt> and on the proc(5) manpage
- ("man 5 proc").

- modifiable sysctl entries will be generated beneath the
- /proc/sys directory. They are explained in the files
- in <file:Documentation/sysctl/>. Note that enabling this
- option will enlarge the kernel by at least 8 KB.

- to support larger 128-bit file identifiers as needed by the
- new realms implementation.
-
- However this new API is not backward compatible with older
- clients. If you really need to run the old Coda userspace
- cache manager then say Y.
-
- For most cases you probably want to say N.

+ This is a virtual file system providing information about the status
+ of the system. "Virtual" means that it doesn't take up any space on
+ your hard disk: the files are created on the fly by the kernel when
+ you try to access them. Also, you cannot read the files with older
+ version of the program less: you need to use more or cat.
+
+ It's totally cool; for example, "cat /proc/interrupts" gives
+ information about what the different IRQs are used for at the moment
+ (there is a small number of Interrupt ReQuest lines in your computer
+ that are used by the attached devices to gain the CPU's attention --
+ often a source of trouble if two devices are mistakenly configured
+ to use the same IRQ). The program procinfo to display some
+ information about your system gathered from the /proc file system.
+
+ Before you can use the /proc file system, it has to be mounted,
+ meaning it has to be given a location in the directory hierarchy.
+ That location should be /proc. A command such as "mount -t proc proc
+ /proc" or the equivalent line in /etc/fstab does the job.
+
+ The /proc file system is explained in the file
+ <file:Documentation/filesystems/proc.txt> and on the proc(5) manpage
+ ("man 5 proc").
+
+ This option will enlarge your kernel by about 67 KB. Several
+ programs depend on this, so everyone should say Y here.

+ The sysctl interface provides a means of dynamically changing

+ a recompile of the kernel or reboot of the system. The primary
+ interface is through /proc/sys. If you say Y here a tree of
+ modifiable sysctl entries will be generated beneath the
+ /proc/sys directory. They are explained in the files
+ in <file:Documentation/sysctl/>. Note that enabling this
+ option will enlarge the kernel by at least 8 KB.
+

+ * GDB assumes that we're a user process being debugged, so
+ * it will send us an SWI command to write into memory as the
+ * debug trap. When an SWI occurs, the next instruction addr is
+ * placed into R14_svc before jumping to the vector trap.
+ * This doesn't work for kernel debugging as we are already in SVC
+ * we would loose the kernel's LR, which is a bad thing. This
+ * is bad thing.
+ *
+ * By doing this as an undefined instruction trap, we force a mode
+ * switch from SVC to UND mode, allowing us to save full kernel state.
+ *
+ * We also define a KGDB_COMPILED_BREAK which can be used to compile
+ * in breakpoints. This is important for things like sysrq-G and for
+ * the initial breakpoint from trap_init().
+ *
+ * Note to ARM HW designers: Add real trap support like SH && PPC to
+ * make our lives much much simpler. :)

- * copy of the task_struct, which is currently not used by gdb,
- * but it may come in handy at some point. All of the registers
- * are stored as part of the upage. The upage should always be
- * only one page long.
- * data: The data segment follows next. We use current->end_text to
- * current->brk to pick up all of the user variables, plus any memory
- * that may have been sbrk'ed. No attempt is made to determine if a
- * page is demand-zero or if a page is totally unused, we just cover
- * the entire range. All of the addresses are rounded in such a way
- * that an integral number of pages is written.
- * stack: We need the stack information in order to get a meaningful
- * backtrace. We need to write the data from usp to
- * current->start_stack, so we round each of these in order to be able
- * to write an integer number of pages.

- counter is expected to have a clock-divider, which can divide the
- system cpu clock by a power of two value from MIN_DIVLOG2 to
- MAX_DIV_LOG2, and a word-size of COUNTER_SIZE bits (the counter
- counts up and resets whenever it's equal to the compare register,
- generating an interrupt or whatever when it does so). The returned
- values are: *DIVLOG2 -- log2 of the desired clock divider and *COUNT
- -- the counter compare value to use. Returns true if it was possible
- to find a reasonable value, otherwise false (and the other return
- values will be set to be as good as possible). */

+ * This function must be called inside the same rcu_read_lock() section as has
+ * been used to lookup the page in the pagecache radix-tree (or page table):
+ * this allows allocators to use a synchronize_rcu() to stabilize _count.
+ *
+ * Unless an RCU grace period has passed, the count of all pages coming out
+ * of the allocator must be considered unstable. page_count may return higher
+ * than expected, and put_page must be able to do the right thing when the
+ * page has been finished with, no matter what it is subsequently allocated
+ * for (because put_page is what is used here to drop an invalid speculative
+ * reference).
+ *
+ * This is the interesting part of the lockless pagecache (and lockless
+ * get_user_pages) locking protocol, where the lookup-side (eg. find_get_page)
+ * has the following pattern:
+ * 1. find page in radix tree
+ * 2. conditionally increment refcount
+ * 3. check the page is still in pagecache (if no, goto 1)
+ *
+ * Remove-side that cares about stability of _count (eg. reclaim) has the

+ * A. atomically check refcount is correct and set it to 0 (atomic_cmpxchg)
+ * B. remove page from pagecache
+ * C. free the page
+ *
+ * There are 2 critical interleavings that matter:
+ * - 2 runs before A: in this case, A sees elevated refcount and bails out
+ * - A runs before 2: in this case, 2 sees zero refcount and retries;
+ * subsequently, B will complete and 1 will find no page, causing the
+ * lookup to return NULL.
+ *
+ * It is possible that between 1 and 2, the page is removed then the exact same
+ * page is inserted into the same position in pagecache. That's OK: the
+ * old find_get_page using tree_lock could equally have run before or after
+ * such a re-insertion, depending on order that locks are granted.
+ *

+ *
+ * This file defines hook entry points called by core code where
+ * user tracing/debugging support might need to do something. These
+ * entry points are called tracehook_*(). Each hook declared below
+ * has a detailed kerneldoc comment giving the context (locking et
+ * al) from which it is called, and the meaning of its return value.
+ *
+ * Each function here typically has only one call site, so it is ok
+ * to have some nontrivial tracehook_*() inlines. In all cases, the
+ * fast path when no tracing is enabled should be very short.
+ *
+ * The purpose of this file and the tracehook_* layer is to consolidate
+ * the interface that the kernel core and arch code uses to enable any
+ * user debugging or tracing facility (such as ptrace). The interfaces
+ * here are carefully documented so that maintainers of core and arch
+ * code do not need to think about the implementation details of the
+ * tracing facilities. Likewise, maintainers of the tracing code do not
+ * need to understand all the calling core or arch code in detail, just
+ * documented circumstances of each call, such as locking conditions.
+ *
+ * If the calling core code changes so that locking is different, then
+ * it is ok to change the interface documented here. The maintainer of
+ * core code changing should notify the maintainers of the tracing code
+ * that they need to work out the change.
+ *
+ * Some tracehook_*() inlines take arguments that the current tracing
+ * implementations might not necessarily use. These function signatures
+ * are chosen to pass in all the information that is on hand in the
+ * caller and might conceivably be relevant to a tracer, so that the
+ * core code won't have to be updated when tracing adds more features.
+ * If a call site changes so that some of those parameters are no longer
+ * already on hand without extra work, then the tracehook_* interface
+ * can change so there is no make-work burden on the core code. The
+ * maintainer of core code changing should notify the maintainers of the
+ * tracing code that they need to work out the change.

- embedded in ALi M1535+ and M1535D+. Note that they aren't all
- enabled by default; you can enable them by saying Y to "/proc file
- system support" and "Sysctl support", and after the /proc file
- system has been mounted, executing the command
-
- command what is enabled
-
- echo 0>/proc/ALi5451 pcm out is also set to S/PDIF out. (Default).
-
- echo 1>/proc/ALi5451 use S/PDIF out to output pcm data.
-
- echo 2>/proc/ALi5451 use S/PDIF out to output non-pcm data.
- (AC3...).
-
- echo 3>/proc/ALi5451 record from Ac97 in(MIC, Line in...).
- (Default).
-
- echo 4>/proc/ALi5451 no matter Ac97 settings, record from S/PDIF
- in.
-
-
- This driver differs slightly from OSS/Free, so PLEASE READ the
- comments at the top of <file:sound/oss/trident.c>.
