+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.

+
+Introduction
+------------
+
+This guide outlines how to alter existing Linux 2.6 client drivers from
+the old to the new new binding methods.
+
+
+Example old-style driver
+------------------------
+
+
+struct example_state {
+ struct i2c_client client;
+ ....
+};
+
+static struct i2c_driver example_driver;
+
+static unsigned short ignore[] = { I2C_CLIENT_END };

+
+ state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
+ if (state == NULL) {
+ dev_err(dev, "failed to create our state\n");
+ return -ENOMEM;
+ }
+
+ example->client.addr = addr;
+ example->client.flags = 0;
+ example->client.adapter = adap;
+
+ i2c_set_clientdata(&state->i2c_client, state);
+ strlcpy(client->i2c_client.name, "example", I2C_NAME_SIZE);
+
+ ret = i2c_attach_client(&state->i2c_client);
+ if (ret < 0) {
+ dev_err(dev, "failed to attach client\n");
+ kfree(state);
+ return ret;
+ }
+
+ dev = &state->i2c_client.dev;
+
+ /* rest of the initialisation goes here. */
+
+ dev_info(dev, "example client created\n");
+
+ return 0;
+}
+
+static int __devexit example_detach(struct i2c_client *client)
+{
+ struct example_state *state = i2c_get_clientdata(client);
+
+ i2c_detach_client(client);
+ kfree(state);
+ return 0;
+}
+
+static int example_attach_adapter(struct i2c_adapter *adap)
+{
+ return i2c_probe(adap, &addr_data, example_attach);
+}
+
+static struct i2c_driver example_driver = {
+ .driver = {
+ .owner = THIS_MODULE,
+ .name = "example",
+ },
+ .attach_adapter = example_attach_adapter,
+ .detach_client = __devexit_p(example_detach),
+ .suspend = example_suspend,
+ .resume = example_resume,
+};
+
+
+Updating the client
+-------------------
+
+The new style binding model will check against a list of supported
+devices and their associated address supplied by the code registering
+the busses. This means that the driver .attach_adapter and
+.detach_adapter methods can be removed, along with the addr_data,
+as follows:
+
+- static struct i2c_driver example_driver;
+
+- static unsigned short ignore[] = { I2C_CLIENT_END };
+- static unsigned short normal_addr[] = { OUR_ADDR, I2C_CLIENT_END };
+
+- I2C_CLIENT_INSMOD;
+
+- static int example_attach_adapter(struct i2c_adapter *adap)
+- {
+- return i2c_probe(adap, &addr_data, example_attach);
+- }
+
+ static struct i2c_driver example_driver = {
+- .attach_adapter = example_attach_adapter,
+- .detach_client = __devexit_p(example_detach),
+ }
+
+Add the probe and remove methods to the i2c_driver, as so:
+
+ static struct i2c_driver example_driver = {
++ .probe = example_probe,
++ .remove = __devexit_p(example_remove),
+ }
+
+Change the example_attach method to accept the new parameters
+which include the i2c_client that it will be working with:
+
+- static int example_attach(struct i2c_adapter *adap, int addr, int kind)
++ static int example_probe(struct i2c_client *client,
++ const struct i2c_device_id *id)
+
+Change the name of example_attach to example_probe to align it with the
+i2c_driver entry names. The rest of the probe routine will now need to be
+changed as the i2c_client has already been setup for use.
+
+The necessary client fields have already been setup before
+the probe function is called, so the following client setup
+can be removed:
+
+- example->client.addr = addr;
+- example->client.flags = 0;
+- example->client.adapter = adap;
+-
+- strlcpy(client->i2c_client.name, "example", I2C_NAME_SIZE);
+
+The i2c_set_clientdata is now:
+
+- i2c_set_clientdata(&state->client, state);
++ i2c_set_clientdata(client, state);
+
+The call to i2c_attach_client is no longer needed, if the probe
+routine exits successfully, then the driver will be automatically
+attached by the core. Change the probe routine as so:
+
+- ret = i2c_attach_client(&state->i2c_client);
+- if (ret < 0) {
+- dev_err(dev, "failed to attach client\n");
+- kfree(state);
+- return ret;
+- }
+
+
+Remove the storage of 'struct i2c_client' from the 'struct example_state'
+as we are provided with the i2c_client in our example_probe. Instead we
+store a pointer to it for when it is needed.
+
+struct example_state {
+- struct i2c_client client;
++ struct i2c_client *client;
+
+the new i2c client as so:
+
+- struct device *dev = &adap->dev; /* to use for dev_ reports */
++ struct device *dev = &i2c_client->dev; /* to use for dev_ reports */
+
+And remove the change after our client is attached, as the driver no
+longer needs to register a new client structure with the core:
+
+- dev = &state->i2c_client.dev;
+
+In the probe routine, ensure that the new state has the client stored
+in it:
+
+static int example_probe(struct i2c_client *i2c_client,
+ const struct i2c_device_id *id)
+{
+ struct example_state *state;
+ struct device *dev = &i2c_client->dev;
+ int ret;
+
+ state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
+ if (state == NULL) {
+ dev_err(dev, "failed to create our state\n");
+ return -ENOMEM;
+ }
+
++ state->client = i2c_client;
+
+Update the detach method, by changing the name to _remove and
+to delete the i2c_detach_client call. It is possible that you
+can also remove the ret variable as it is not not needed for
+any of the core functions.
+
+- static int __devexit example_detach(struct i2c_client *client)
++ static int __devexit example_remove(struct i2c_client *client)
+{
+ struct example_state *state = i2c_get_clientdata(client);
+
+- i2c_detach_client(client);
+
+And finally ensure that we have the correct ID table for the i2c-core
+and other utilities:
+
++ struct i2c_device_id example_idtable[] = {
++ { "example", 0 },
++ { }
++};
++
++MODULE_DEVICE_TABLE(i2c, example_idtable);
+
+static struct i2c_driver example_driver = {
+ .driver = {
+ .owner = THIS_MODULE,
+ .name = "example",
+ },
++ .id_table = example_ids,
+
+
+Our driver should now look like this:
+
+struct example_state {
+ struct i2c_client *client;
+ ....
+};
+
+static int example_probe(struct i2c_client *client,
+ const struct i2c_device_id *id)
+{
+ struct example_state *state;
+ struct device *dev = &client->dev;
+
+ state = kzalloc(sizeof(struct example_state), GFP_KERNEL);
+ if (state == NULL) {
+ dev_err(dev, "failed to create our state\n");
+ return -ENOMEM;
+ }
+
+ state->client = client;
+ i2c_set_clientdata(client, state);
+
+ /* rest of the initialisation goes here. */
+
+ dev_info(dev, "example client created\n");
+
+ return 0;
+}
+
+static int __devexit example_remove(struct i2c_client *client)
+{
+ struct example_state *state = i2c_get_clientdata(client);
+
+ kfree(state);
+ return 0;
+}
+
+static struct i2c_device_id example_idtable[] = {
+ { "example", 0 },
+ { }
+};
+

+ .probe = example_probe,
+ .remove = __devexit_p(example_remove),

+ * module parameters:
+ * type:
+ * By default (0), the card is automatically detected.
+ * 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.

+ * 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)

+ * 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)

+ * 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.

+/*
+ * 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
+ *

+ * ------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.

+ 1 = we use u-Law
+
+ * limit:

+ 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

+
+ * 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:

+* 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.

+ * of_modalias_table: Table of explicit compatible ==> modalias mappings
+ *
+ * This table allows particulare compatible property values to be mapped
+ * to modalias strings. This is useful for busses which do not directly
+ * understand the OF device tree but are populated based on data contained
+ * within the device tree. SPI and I2C are the two current users of this
+ * table.
+ *
+ * In most cases, devices do not need to be listed in this table because
+ * the modalias value can be derived directly from the compatible table.
+ * However, if for any reason a value cannot be derived, then this table
+ * provides a method to override the implicit derivation.
+ *
+ * At the moment, a single table is used for all bus types because it is
+ * assumed that the data size is small and that the compatible values
+ * should already be distinct enough to differentiate between SPI, I2C
+ * and other devices.

+ * Based on the value of the compatible property, this routine will determine

+ *
+ * First method is to lookup the compatible value in of_modalias_table.

+ * If the page is free (_count == 0), then _count is untouched, and 0

+ *
+ * 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
+ * following (with tree_lock held for write):
+ * 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

+ * 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

+
+Diffconfig is a simple utility for comparing two .config files.
+Using standard diff to compare .config files often includes extraneous and
+distracting information. This utility produces sorted output with only the
+changes in configuration values between the two files.
+
+Added and removed items are shown with a leading plus or minus, respectively.
+Changed items show the old and new values on a single line.
+
+If -m is specified, then output will be in "merge" style, which has the
+changed and new values in kernel config option format.
+
+If no config files are specified, .config and .config.old are used.
+
+Example usage:
+ $ diffconfig .config config-with-some-changes
