+Kernel driver abituguru
+=======================
+
+Supported chips:
+ * Abit uGuru (Hardware Monitor part only)
+ Prefix: 'abituguru'
+ Addresses scanned: ISA 0x0E0
+ Datasheet: Not available, this driver is based on reverse engineering.
+ A "Datasheet" has been written based on the reverse engineering it
+ should be available in the same dir as this file under the name
+ abituguru-datasheet.
+
+Authors:
+ Hans de Goede <j.w.r.degoede@hhs.nl>,
+ (Initial reverse engineering done by Olle Sandberg
+ <ollebull@gmail.com>)
+
+
+Module Parameters
+-----------------
+
+* force: bool Force detection. Note this parameter only causes the
+ detection to be skipped, if the uGuru can't be read
+ the module initialization (insmod) will still fail.
+* fan_sensors: int Tell the driver how many fan speed sensors there are
+ on your motherboard. Default: 0 (autodetect).
+* pwms: int Tell the driver how many fan speed controls (fan
+ pwms) your motherboard has. Default: 0 (autodetect).
+* verbose: int How verbose should the driver be? (0-3):
+ 0 normal output
+ 1 + verbose error reporting
+ 2 + sensors type probing info\n"
+ 3 + retryable error reporting
+ Default: 2 (the driver is still in the testing phase)
+
+Notice if you need any of the first three options above please insmod the
+driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:
+dmesg | grep abituguru
+
+
+Description
+-----------
+
+This driver supports the hardware monitoring features of the Abit uGuru chip
+found on Abit uGuru featuring motherboards (most modern Abit motherboards).
+
+The uGuru chip in reality is a Winbond W83L950D in disguise (despite Abit
+claiming it is "a new microprocessor designed by the ABIT Engineers").
+Unfortunatly this doesn't help since the W83L950D is a generic
+microcontroller with a custom Abit application running on it.
+
+Despite Abit not releasing any information regarding the uGuru, Olle
+Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
+of the uGuru. Without his work this driver would not have been possible.
+
+Known Issues
+------------
+
+The voltage and frequency control parts of the Abit uGuru are not supported.

+uGuru datasheet
+===============
+
+First of all, what I know about uGuru is no fact based on any help, hints or
+datasheet from Abit. The data I have got on uGuru have I assembled through
+my weak knowledge in "backwards engineering".
+And just for the record, you may have noticed uGuru isn't a chip developed by
+Abit, as they claim it to be. It's realy just an microprocessor (uC) created by
+Winbond (W83L950D). And no, reading the manual for this specific uC or
+mailing Windbond for help won't give any usefull data about uGuru, as it is
+the program inside the uC that is responding to calls.
+
+Olle Sandberg <ollebull@gmail.com>, 2005-05-25
+
+
+Original version by Olle Sandberg who did the heavy lifting of the initial
+reverse engineering. This version has been almost fully rewritten for clarity
+and extended with write support and info on more databanks, the write support
+is once again reverse engineered by Olle the additional databanks have been
+reverse engineered by me. I would like to express my thanks to Olle, this
+document and the Linux driver could not have been written without his efforts.
+
+Note: because of the lack of specs only the sensors part of the uGuru is
+described here and not the CPU / RAM / etc voltage & frequency control.
+
+Hans de Goede <j.w.r.degoede@hhs.nl>, 28-01-2006
+
+
+Detection
+=========
+
+As far as known the uGuru is always placed at and using the (ISA) I/O-ports
+0xE0 and 0xE4, so we don't have to scan any port-range, just check what the two
+ports are holding for detection. We will refer to 0xE0 as CMD (command-port)
+and 0xE4 as DATA because Abit refers to them with these names.
+
+If DATA holds 0x00 or 0x08 and CMD holds 0x00 or 0xAC an uGuru could be
+present. We have to check for two different values at data-port, because
+after a reboot uGuru will hold 0x00 here, but if the driver is removed and
+later on attached again data-port will hold 0x08, more about this later.
+
+After wider testing of the Linux kernel driver some variants of the uGuru have
+turned up which will hold 0x00 instead of 0xAC at the CMD port, thus we also
+have to test CMD for two different values. On these uGuru's DATA will initally
+hold 0x09 and will only hold 0x08 after reading CMD first, so CMD must be read
+first!
+
+To be really sure an uGuru is present a test read of one or more register
+sets should be done.
+
+
+Reading / Writing
+=================
+
+Addressing
+----------
+
+The uGuru has a number of different addressing levels. The first addressing
+level we will call banks. A bank holds data for one or more sensors. The data
+in a bank for a sensor is one or more bytes large.
+
+The number of bytes is fixed for a given bank, you should always read or write
+that many bytes, reading / writing more will fail, the results when writing
+less then the number of bytes for a given bank are undetermined.
+
+See below for all known bank addresses, numbers of sensors in that bank,
+number of bytes data per sensor and contents/meaning of those bytes.
+
+Although both this document and the kernel driver have kept the sensor
+terminoligy for the addressing within a bank this is not 100% correct, in
+bank 0x24 for example the addressing within the bank selects a PWM output not
+a sensor.
+
+Notice that some banks have both a read and a write address this is how the
+uGuru determines if a read from or a write to the bank is taking place, thus
+when reading you should always use the read address and when writing the
+write address. The write address is always one (1) more then the read address.
+
+
+uGuru ready
+-----------
+
+Before you can read from or write to the uGuru you must first put the uGuru
+in "ready" mode.
+
+To put the uGuru in ready mode first write 0x00 to DATA and then wait for DATA
+to hold 0x09, DATA should read 0x09 within 250 read cycles.
+
+Next CMD _must_ be read and should hold 0xAC, usually CMD will hold 0xAC the
+first read but sometimes it takes a while before CMD holds 0xAC and thus it
+has to be read a number of times (max 50).
+
+After reading CMD, DATA should hold 0x08 which means that the uGuru is ready
+for input. As above DATA will usually hold 0x08 the first read but not always.
+This step can be skipped, but it is undetermined what happens if the uGuru has
+not yet reported 0x08 at DATA and you proceed with writing a bank address.
+
+
+Sending bank and sensor addresses to the uGuru
+----------------------------------------------
+
+First the uGuru must be in "ready" mode as described above, DATA should hold
+0x08 indicating that the uGuru wants input, in this case the bank address.
+
+Next write the bank address to DATA. After the bank address has been written
+wait for to DATA to hold 0x08 again indicating that it wants / is ready for
+more input (max 250 reads).
+
+Once DATA holds 0x08 again write the sensor address to CMD.
+
+
+Reading
+-------
+
+First send the bank and sensor addresses as described above.
+Then for each byte of data you want to read wait for DATA to hold 0x01
+which indicates that the uGuru is ready to be read (max 250 reads) and once
+DATA holds 0x01 read the byte from CMD.
+
+Once all bytes have been read data will hold 0x09, but there is no reason to
+test for this. Notice that the number of bytes is bank address dependent see
+above and below.
+
+After completing a successfull read it is advised to put the uGuru back in
+ready mode, so that it is ready for the next read / write cycle. This way
+if your program / driver is unloaded and later loaded again the detection
+algorithm described above will still work.
+
+
+
+Writing
+-------
+
+First send the bank and sensor addresses as described above.
+Then for each byte of data you want to write wait for DATA to hold 0x00
+which indicates that the uGuru is ready to be written (max 250 reads) and
+once DATA holds 0x00 write the byte to CMD.
+
+Once all bytes have been written wait for DATA to hold 0x01 (max 250 reads)
+don't ask why this is the way it is.
+
+Once DATA holds 0x01 read CMD it should hold 0xAC now.
+
+After completing a successfull write it is advised to put the uGuru back in
+ready mode, so that it is ready for the next read / write cycle. This way
+if your program / driver is unloaded and later loaded again the detection
+algorithm described above will still work.
+
+
+Gotchas
+-------
+
+After wider testing of the Linux kernel driver some variants of the uGuru have
+turned up which do not hold 0x08 at DATA within 250 reads after writing the
+bank address. With these versions this happens quite frequent, using larger
+timeouts doesn't help, they just go offline for a second or 2, doing some
+internal callibration or whatever. Your code should be prepared to handle
+this and in case of no response in this specific case just goto sleep for a
+while and then retry.
+
+
+Address Map
+===========
+
+Bank 0x20 Alarms (R)
+--------------------
+This bank contains 0 sensors, iow the sensor address is ignored (but must be
+written) just use 0. Bank 0x20 contains 3 bytes:
+
+Byte 0:
+This byte holds the alarm flags for sensor 0-7 of Sensor Bank1, with bit 0
+corresponding to sensor 0, 1 to 1, etc.
+
+Byte 1:
+This byte holds the alarm flags for sensor 8-15 of Sensor Bank1, with bit 0
+corresponding to sensor 8, 1 to 9, etc.
+
+Byte 2:
+This byte holds the alarm flags for sensor 0-5 of Sensor Bank2, with bit 0
+corresponding to sensor 0, 1 to 1, etc.
+
+
+Bank 0x21 Sensor Bank1 Values / Readings (R)
+--------------------------------------------
+This bank contains 16 sensors, for each sensor it contains 1 byte.
+So far the following sensors are known to be available on all motherboards:
+Sensor 0 CPU temp
+Sensor 1 SYS temp
+Sensor 3 CPU core volt
+Sensor 4 DDR volt
+Sensor 10 DDR Vtt volt
+Sensor 15 PWM temp
+
+Byte 0:
+This byte holds the reading from the sensor. Sensors in Bank1 can be both
+volt and temp sensors, this is motherboard specific. The uGuru however does
+seem to know (be programmed with) what kindoff sensor is attached see Sensor
+Bank1 Settings description.
+
+Volt sensors use a linear scale, a reading 0 corresponds with 0 volt and a
+reading of 255 with 3494 mV. The sensors for higher voltages however are
+connected through a division circuit. The currently known division circuits
+in use result in ranges of: 0-4361mV, 0-6248mV or 0-14510mV. 3.3 volt sources
+use the 0-4361mV range, 5 volt the 0-6248mV and 12 volt the 0-14510mV .
+
+Temp sensors also use a linear scale, a reading of 0 corresponds with 0 degree
+Celsius and a reading of 255 with a reading of 255 degrees Celsius.
+
+
+Bank 0x22 Sensor Bank1 Settings (R)
+Bank 0x23 Sensor Bank1 Settings (W)
+-----------------------------------
+

+Alarm behaviour for the selected sensor. A 1 enables the described behaviour.
+Bit 0: Give an alarm if measured temp is over the warning threshold (RW) *

+Bit 6: 1 if alarm cause measured volt is under the min threshold (R)
+Bit 7: Volt sensor: Shutdown if alarm persist for more then 4 seconds (RW)
+ Temp sensor: Shutdown if temp is over the shutdown threshold (RW)
+
+* This bit is only honored/used by the uGuru if a temp sensor is connected
+** This bit is only honored/used by the uGuru if a volt sensor is connected
+Note with some trickery this can be used to find out what kinda sensor is
+detected see the Linux kernel driver for an example with many comments on
+how todo this.

+low threshold temp (specified in byte 3)
+
+Byte 2:
+0-255 = 0-12v (linear), specify voltage at which fan will rotate when above
+high threshold temp (specified in byte 4)
+
+Byte 3:
+Low threshold temp (scale as bank 0x21)
+
+byte 4:

+
+
+Bank 0x26 Sensors Bank2 Values / Readings (R)
+---------------------------------------------
+
+This bank contains 6 sensors (AFAIK), for each sensor it contains 1 byte.

+
+
+Warning for the adventerous
+===========================
+
+A word of caution to those who want to experiment and see if they can figure
+the voltage / clock programming out, I tried reading and only reading banks
+0-0x30 with the reading code used for the sensor banks (0x20-0x28) and this
+resulted in a _permanent_ reprogramming of the voltages, luckily I had the
+sensors part configured so that it would shutdown my system on any out of spec
+voltages which proprably safed my computer (after a reboot I managed to
+immediatly enter the bios and reload the defaults). This probably means that
+the read/write cycle for the non sensor part is different from the sensor part.

+Description
+-----------
+
+This driver implements support for the National Semiconductor LM70
+temperature sensor.
+
+The LM70 temperature sensor chip supports a single temperature sensor.
+It communicates with a host processor (or microcontroller) via an
+SPI/Microwire Bus interface.
+
+Communication with the LM70 is simple: when the temperature is to be sensed,
+the driver accesses the LM70 using SPI communication: 16 SCLK cycles
+comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's
+complement digital temperature (sent via the SIO line), is available in the
+driver for interpretation. This driver makes use of the kernel's in-core
+SPI support.

+Author: Hartmut Rick <linux@rick.claranet.de>
+ Special thanks to Jean Delvare for careful checking

+
+
+Description
+-----------
+
+This driver implements support for the hardware sensor capabilities
+of the SMSC LPC47M192 and LPC47M997 Super-I/O chips.
+
+These chips support 3 temperature channels and 8 voltage inputs
+as well as CPU voltage VID input.
+
+They do also have fan monitoring and control capabilities, but the
+these features are accessed via ISA bus and are not supported by this
+driver. Use the 'smsc47m1' driver for fan monitoring and control.
+
+Voltages and temperatures are measured by an 8-bit ADC, the resolution
+of the temperatures is 1 bit per degree C.
+Voltages are scaled such that the nominal voltage corresponds to
+192 counts, i.e. 3/4 of the full range. Thus the available range for
+each voltage channel is 0V ... 255/192*(nominal voltage), the resolution
+is 1 bit per (nominal voltage)/192.
+Both voltage and temperature values are scaled by 1000, the sys files
+show voltages in mV and temperatures in units of 0.001 degC.
+
+The +12V analog voltage input channel (in4_input) is multiplexed with
+bit 4 of the encoded CPU voltage. This means that you either get
+a +12V voltage measurement or a 5 bit CPU VID, but not both.
+The default setting is to use the pin as 12V input, and use only 4 bit VID.
+This driver assumes that the information in the configuration register
+is correct, i.e. that the BIOS has updated the configuration if
+the motherboard has this input wired to VID4.
+
+The temperature and voltage readings are updated once every 1.5 seconds.
+Reading them more often repeats the same values.

+in5_input - Vcc voltage input (nominal 3.3V)

+in7_input - +1.8V voltage input
+
+in[0-7]_min,
+in[0-7]_max - lower and upper alarm thresholds for in[0-7]_input reading
+
+ All voltages are read and written in mV.
+
+in[0-7]_alarm - alarm flags for voltage inputs
+ These files read '1' in case of alarm, '0' otherwise.
+

+temp[2-3]_input - temperature measured by external diodes (one of these would
+ typically be wired to the diode inside the CPU)
+
+temp[1-3]_min,
+temp[1-3]_max - lower and upper alarm thresholds for temperatures
+
+temp[1-3]_offset - temperature offset registers
+ The chip adds the offsets stored in these registers to
+ the corresponding temperature readings.
+ Note that temp1 and temp2 offsets share the same register,
+ they cannot both be different from zero at the same time.
+ Writing a non-zero number to one of them will reset the other
+ offset to zero.
+
+ All temperatures and offsets are read and written in
+ units of 0.001 degC.
+
+temp[1-3]_alarm - alarm flags for temperature inputs, '1' in case of alarm,
+ '0' otherwise.
+temp[2-3]_input_fault - diode fault flags for temperature inputs 2 and 3.
+ A fault is detected if the two pins for the corresponding
+ sensor are open or shorted, or any of the two is shorted
+ to ground or Vcc. '1' indicates a diode fault.
+
+cpu0_vid - CPU voltage as received from the CPU
+
+vrm - CPU VID standard used for decoding CPU voltage
+
+ The *_min, *_max, *_offset and vrm files can be read and

+ 0x4a and 0x4b.
+
+
+Description
+-----------
+
+This driver implements support for the Winbond W83791D chip.
+
+Detection of the chip can sometimes be foiled because it can be in an
+internal state that allows no clean access (Bank with ID register is not
+currently selected). If you know the address of the chip, use a 'force'
+parameter; this will put it into a more well-behaved state first.
+
+The driver implements three temperature sensors, five fan rotation speed
+sensors, and ten voltage sensors.
+
+Temperatures are measured in degrees Celsius and measurement resolution is 1
+degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
+the temperature gets higher than the Overtemperature Shutdown value; it stays
+on until the temperature falls below the Hysteresis value.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4, 8 for fan 1/2/3
+and 1, 2, 4, 8, 16, 32, 64 or 128 for fan 4/5) to give the readings more
+range or accuracy.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit.
+
+Alarms are provided as output from a "realtime status register". The
+following bits are defined:
+
+bit - alarm on:
+0 - Vcore
+1 - VINR0
+2 - +3.3VIN
+3 - 5VDD
+4 - temp1
+5 - temp2
+6 - fan1
+7 - fan2
+8 - +12VIN

+20 - VBAT
+21 - fan4
+22 - fan5
+23 - reserved
+
+When an alarm goes off, you can be warned by a beeping signal through your
+computer speaker. It is possible to enable all beeping globally, or only
+the beeping for some alarms.
+
+The driver only reads the chip values each 3 seconds; reading them more
+often will do no harm, but will return 'old' values.

+
+i2c-ocores is an i2c bus driver for the OpenCores.org I2C controller
+IP core by Richard Herveille.
+
+Usage
+-----
+
+i2c-ocores uses the platform bus, so you need to provide a struct
+platform_device with the base address and interrupt number. The
+dev.platform_data of the device should also point to a struct
+ocores_i2c_platform_data (see linux/i2c-ocores.h) describing the
+distance between registers and the input clock speed.
+
+E.G. something like:
+
+static struct resource ocores_resources[] = {
+ [0] = {
+ .start = MYI2C_BASEADDR,
+ .end = MYI2C_BASEADDR + 8,

+ .start = MYI2C_IRQ,
+ .end = MYI2C_IRQ,
+ .flags = IORESOURCE_IRQ,
+ },
+};
+

+ .regstep = 2, /* two bytes between registers */
+ .clock_khz = 50000, /* input clock of 50MHz */

+SELINUX SUPPORT
+===============
+
+The security class "key" has been added to SELinux so that mandatory access
+controls can be applied to keys created within various contexts. This support
+is preliminary, and is likely to change quite significantly in the near future.
+Currently, all of the basic permissions explained above are provided in SELinux
+as well; SE Linux is simply invoked after all basic permission checks have been
+performed.
+
+Each key is labeled with the same context as the task to which it belongs.
+Typically, this is the same task that was running when the key was created.
+The default keyrings are handled differently, but in a way that is very
+intuitive:
+
+ (*) The user and user session keyrings that are created when the user logs in
+ are currently labeled with the context of the login manager.
+
+ (*) The keyrings associated with new threads are each labeled with the context
+ of their associated thread, and both session and process keyrings are
+ handled similarly.
+
+Note, however, that the default keyrings associated with the root user are
+labeled with the default kernel context, since they are created early in the
+boot process, before root has a chance to log in.

+Then provided control buffer is being written to the wire.
+2. reading. This will issue reading eeprom response.

+Userspace communication protocol over connector [1].
+
+
+Message types.
+=============
+
+There are three types of messages between w1 core and userspace:
+1. Events. They are generated each time new master or slave device found
+ either due to automatic or requested search.
+2. Userspace commands. Includes read/write and search/alarm search comamnds.
+3. Replies to userspace commands.
+
+
+Protocol.
+========
+
+[struct cn_msg] - connector header. It's length field is equal to size of the attached data.
+[struct w1_netlink_msg] - w1 netlink header.
+ __u8 type - message type.
+ W1_SLAVE_ADD/W1_SLAVE_REMOVE - slave add/remove events.
+ W1_MASTER_ADD/W1_MASTER_REMOVE - master add/remove events.
+ W1_MASTER_CMD - userspace command for bus master device (search/alarm search).
+ W1_SLAVE_CMD - userspace command for slave device (read/write/ search/alarm search
+ for bus master device where given slave device found).
+ __u8 res - reserved
+ __u16 len - size of attached to this header data.
+ union {
+ __u8 id; - slave unique device id
+ struct w1_mst {
+ __u32 id; - master's id.
+ __u32 res; - reserved
+ } mst;
+ } id;
+
+[strucrt w1_netlink_cmd] - command for gived master or slave device.
+ __u8 cmd - command opcode.
+ W1_CMD_READ - read command.
+ W1_CMD_WRITE - write command.
+ W1_CMD_SEARCH - search command.
+ W1_CMD_ALARM_SEARCH - alarm search command.
+ __u8 res - reserved
+ __u16 len - length of data for this command.
+ For read command data must be allocated like for write command.
+ __u8 data[0] - data for this command.
+
+
+Each connector message can include one or more w1_netlink_msg with zero of more attached w1_netlink_cmd messages.
+
+For event messages there are no w1_netlink_cmd embedded structures, only connector header
+and w1_netlink_msg strucutre with "len" field being zero and filled type (one of event types)
+and id - either 8 bytes of slave unique id in host order, or master's id, which is assigned
+to bus master device when it is added to w1 core.
+
+Currently replies to userspace commands are only generated for read command request.
+One reply is generated exactly for one w1_netlink_cmd read request.
+Replies are not combined when sent - i.e. typical reply messages looks like the following:
+[cn_msg][w1_netlink_msg][w1_netlink_cmd]
+cn_msg.len = sizeof(struct w1_netlink_msg) + sizeof(struct w1_netlink_cmd) + cmd->len;
+w1_netlink_msg.len = sizeof(struct w1_netlink_cmd) + cmd->len;
+w1_netlink_cmd.len = cmd->len;
+
+
+Operation steps in w1 core when new command is received.
+=======================================================
+
+When new message (w1_netlink_msg) is received w1 core detects if it is master of slave request,
+according to w1_netlink_msg.type field.
+Then master or slave device is searched for.
+When found, master device (requested or those one on where slave device is found) is locked.
+If slave command is requested, then reset/select procedure is started to select given device.
+
+Then all requested in w1_netlink_msg operations are performed one by one.
+If command requires reply (like read command) it is sent on command completion.
+
+When all commands (w1_netlink_cmd) are processed muster device is unlocked
+and next w1_netlink_msg header processing started.
+
+
+Connector [1] specific documentation.
+====================================
+
+Each connector message includes two u32 fields as "address".
+w1 uses CN_W1_IDX and CN_W1_VAL defined in include/linux/connector.h header.
+Each message also includes sequence and acknowledge numbers.
+Sequence number for event messages is appropriate bus master sequence number increased with
+each event message sent "through" this master.
+Sequence number for userspace requests is set by userspace application.
+Sequence number for reply is the same as was in request, and
+acknowledge number is set to seq+1.
+
+
+Additional documantion, source code examples.

+This archive includes userspace application w1d.c which
+uses read/write/search commands for all master/slave devices found on the bus.

* cpufreq driver for Enhanced SpeedStep, as found in Intel's Pentium

* Despite the "SpeedStep" in the name, this is almost entirely unlike

+ * We have two different locks in the bcm43xx driver.

+ * We have three types of helper function pairs to utilize these locks.
+ * (Always use the helper functions.)
+ * 1) bcm43xx_{un}lock_noirq():
+ * Takes bcm->mutex. Does _not_ protect against IRQ concurrency,
+ * so it is almost always unsafe, if device IRQs are enabled.
+ * So only use this, if device IRQs are masked.
+ * Locking may sleep.
+ * You can sleep within the critical section.
+ * 2) bcm43xx_{un}lock_irqonly():
+ * Takes bcm->irq_lock. Does _not_ protect against
+ * bcm43xx_lock_noirq() critical sections.
+ * Does only protect against the IRQ handler path and other
+ * irqonly() critical sections.
+ * Locking does not sleep.
+ * You must not sleep within the critical section.
+ * 3) bcm43xx_{un}lock_irqsafe():
+ * This is the cummulative lock and takes both, mutex and irq_lock.
+ * Protects against noirq() and irqonly() critical sections (and
+ * the IRQ handler path).
+ * Locking may sleep.
+ * You must not sleep within the critical section.

- not specified for values of the flush parameter other than Z_SYNC_FLUSH
- and Z_FINISH, but the current implementation actually flushes as much output
- as possible anyway.
+ The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,
+ Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
+ output as possible to the output buffer. Z_BLOCK requests that inflate() stop
+ if and when it gets to the next deflate block boundary. When decoding the

+ the header and before the first block. When doing a raw inflate, inflate()
+ will go ahead and process the first block, and will return when it gets to
+ the end of that block, or when it runs out of data.
+
+ The Z_BLOCK option assists in appending to or combining deflate streams.
+ Also to assist in this, on return inflate() will set strm->data_type to the
+ number of unused bits in the last byte taken from strm->next_in, plus 64
+ if inflate() is currently decoding the last block in the deflate stream,

The windowBits parameter is the base two logarithm of the maximum window

+ format is developed using the raw deflate format for compressed data, it is
+ recommended that a check value such as an adler32 or a crc32 be applied to
+ the uncompressed data as is done in the zlib, gzip, and zip formats. For
+ most applications, the zlib format should be used as is. Note that comments
+ above on the use in deflateInit2() applies to the magnitude of windowBits.

- Notes beyond the 1.93a appnote.txt:
-
- 1. Distance pointers never point before the beginning of the output
- stream.
- 2. Distance pointers can point back across blocks, up to 32k away.
- 3. There is an implied maximum of 7 bits for the bit length table and
- 15 bits for the actual data.
- 4. If only one code exists, then it is encoded using one bit. (Zero
- would be more efficient, but perhaps a little confusing.) If two
- codes exist, they are coded using one bit each (0 and 1).
- 5. There is no way of sending zero distance codes--a dummy must be
- sent if there are none. (History: a pre 2.0 version of PKZIP would
- store blocks with no distance codes, but this was discovered to be
- too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
- zero distance codes, which is sent as one code of zero bits in
- length.
- 6. There are up to 286 literal/length codes. Code 256 represents the
- end-of-block. Note however that the static length tree defines
- 288 codes just to fill out the Huffman codes. Codes 286 and 287
- cannot be used though, since there is no length base or extra bits
- defined for them. Similarily, there are up to 30 distance codes.
- However, static trees define 32 codes (all 5 bits) to fill out the
- Huffman codes, but the last two had better not show up in the data.
- 7. Unzip can check dynamic Huffman blocks for complete code sets.
- The exception is that a single code would not be complete (see #4).
- 8. The five bits following the block type is really the number of
- literal codes sent minus 257.
- 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
- (1+6+6). Therefore, to output three times the length, you output
- three codes (1+1+1), whereas to output four times the same length,
- you only need two codes (1+3). Hmm.
- 10. In the tree reconstruction algorithm, Code = Code + Increment
- only if BitLength(i) is not zero. (Pretty obvious.)
- 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
- 12. Note: length code 284 can represent 227-258, but length code 285
- really is 258. The last length deserves its own, short code
- since it gets used a lot in very redundant files. The length
- 258 is special since 258 - 3 (the min match length) is 255.
- 13. The literal/length and distance code bit lengths are read as a
- single stream of lengths. It is possible (and advantageous) for
- a repeat code (16, 17, or 18) to go across the boundary between
- the two sets of lengths.

+ inflate() uses a state machine to process as much input data and generate as
+ much output data as possible before returning. The state machine is
+ structured roughly as follows:
+
+ for (;;) switch (state) {
+ ...
+ case STATEn:
+ if (not enough input data or output space to make progress)
+ return;
+ ... make progress ...
+ state = STATEm;
+ break;
+ ...
+ }
+
+ so when inflate() is called again, the same case is attempted again, and
+ if the appropriate resources are provided, the machine proceeds to the
+ next state. The NEEDBITS() macro is usually the way the state evaluates
+ whether it can proceed or should return. NEEDBITS() does the return if
+ the requested bits are not available. The typical use of the BITS macros
+ is:
+
+ NEEDBITS(n);
+ ... do something with BITS(n) ...
+ DROPBITS(n);
+
+ where NEEDBITS(n) either returns from inflate() if there isn't enough
+ input left to load n bits into the accumulator, or it continues. BITS(n)
+ gives the low n bits in the accumulator. When done, DROPBITS(n) drops
+ the low n bits off the accumulator. INITBITS() clears the accumulator
+ and sets the number of available bits to zero. BYTEBITS() discards just
+ enough bits to put the accumulator on a byte boundary. After BYTEBITS()
+ and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+ NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+ if there is no input available. The decoding of variable length codes uses
+ PULLBYTE() directly in order to pull just enough bytes to decode the next
+ code, and no more.
+
+ Some states loop until they get enough input, making sure that enough
+ state information is maintained to continue the loop where it left off
+ if NEEDBITS() returns in the loop. For example, want, need, and keep
+ would all have to actually be part of the saved state in case NEEDBITS()
+ returns:
+
+ case STATEw:
+ while (want < need) {
+ NEEDBITS(n);
+ keep[want++] = BITS(n);
+ DROPBITS(n);
+ }
+ state = STATEx;
+ case STATEx:
+
+ As shown above, if the next state is also the next case, then the break
+ is omitted.
+
+ A state may also return if there is not enough output space available to
+ complete that state. Those states are copying stored data, writing a
+ literal byte, and copying a matching string.
+
+ When returning, a "goto inf_leave" is used to update the total counters,
+ update the check value, and determine whether any progress has been made
+ during that inflate() call in order to return the proper return code.
+ Progress is defined as a change in either strm->avail_in or strm->avail_out.
+ When there is a window, goto inf_leave will update the window with the last
+ output written. If a goto inf_leave occurs in the middle of decompression
+ and there is no window currently, goto inf_leave will create one and copy
+ output to the window for the next call of inflate().
+
+ In this implementation, the flush parameter of inflate() only affects the
+ return code (per zlib.h). inflate() always writes as much as possible to
+ strm->next_out, given the space available and the provided input--the effect
+ documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers
+ the allocation of and copying into a sliding window until necessary, which
+ provides the effect documented in zlib.h for Z_FINISH when the entire input
+ stream available. So the only thing the flush parameter actually does is:
+ when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it
+ will return Z_BUF_ERROR if it has not reached the end of the stream.

- Huffman code decoding is performed using a multi-level table lookup.
- The fastest way to decode is to simply build a lookup table whose
- size is determined by the longest code. However, the time it takes
- to build this table can also be a factor if the data being decoded
- is not very long. The most common codes are necessarily the
- shortest codes, so those codes dominate the decoding time, and hence
- the speed. The idea is you can have a shorter table that decodes the
- shorter, more probable codes, and then point to subsidiary tables for
- the longer codes. The time it costs to decode the longer codes is
- then traded against the time it takes to make longer tables.
-
- This results of this trade are in the variables lbits and dbits
- below. lbits is the number of bits the first level table for literal/
- length codes can decode in one step, and dbits is the same thing for
- the distance codes. Subsequent tables are also less than or equal to
- those sizes. These values may be adjusted either when all of the
- codes are shorter than that, in which case the longest code length in
- bits is used, or when the shortest code is *longer* than the requested
- table size, in which case the length of the shortest code in bits is
- used.
-
- There are two different values for the two tables, since they code a
- different number of possibilities each. The literal/length table
- codes 286 possible values, or in a flat code, a little over eight
- bits. The distance table codes 30 possible values, or a little less
- than five bits, flat. The optimum values for speed end up being
- about one bit more than those, so lbits is 8+1 and dbits is 5+1.
- The optimum values may differ though from machine to machine, and
- possibly even between compilers. Your mileage may vary.
+ Build a set of tables to decode the provided canonical Huffman code.
+ The code lengths are lens[0..codes-1]. The result starts at *table,
+ whose indices are 0..2^bits-1. work is a writable array of at least
+ lens shorts, which is used as a work area. type is the type of code
+ to be generated, CODES, LENS, or DISTS. On return, zero is success,
+ -1 is an invalid code, and +1 means that ENOUGH isn't enough. table
+ on return points to the next available entry's address. bits is the
+ requested root table index bits, and on return it is the actual root
+ table index bits. It will differ if the request is greater than the
+ longest code or if it is less than the shortest code.

+ Process a set of code lengths to create a canonical Huffman code. The
+ code lengths are lens[0..codes-1]. Each length corresponds to the
+ symbols 0..codes-1. The Huffman code is generated by first sorting the
+ symbols by length from short to long, and retaining the symbol order
+ for codes with equal lengths. Then the code starts with all zero bits
+ for the first code of the shortest length, and the codes are integer
+ increments for the same length, and zeros are appended as the length
+ increases. For the deflate format, these bits are stored backwards
+ from their more natural integer increment ordering, and so when the
+ decoding tables are built in the large loop below, the integer codes
+ are incremented backwards.
+ This routine assumes, but does not check, that all of the entries in
+ lens[] are in the range 0..MAXBITS. The caller must assure this.
+ 1..MAXBITS is interpreted as that code length. zero means that that
+ symbol does not occur in this code.

+ *
+ *
+ * This is a driver for the pcm3052 codec chip (codenamed Onyx)
+ * that is present in newer Apple hardware (with digital output).
+ *
+ * The Onyx codec has the following connections (listed by the bit
+ * to be used in aoa_codec.connected):
+ * 0: analog output
+ * 1: digital output
+ * 2: line input
+ * 3: microphone input
+ * Note that even though I know of no machine that has for example
+ * the digital output connected but not the analog, I have handled
+ * all the different cases in the code so that this driver may serve
+ * as a good example of what to do.
+ *
+ * NOTE: This driver assumes that there's at most one chip to be
+ * used with one alsa card, in form of creating all kinds
+ * of mixer elements without regard for their existence.
+ * But snd-aoa assumes that there's at most one card, so
+ * this means you can only have one onyx on a system. This
+ * should probably be fixed by changing the assumption of
+ * having just a single card on a system, and making the
+ * 'card' pointer accessible to anyone who needs it instead
+ * of hiding it in the aoa_snd_* functions...

+ * Open questions:

+ * FIXMEs:
+ * - This codec driver doesn't honour the 'connected'

+ * - Driver assumes that the microphone is always

+ * flag, maybe the codec should have 3 different
+ * bits for the three different possibilities how

+ * But as long as I don't see any hardware hooked

+ * - As Apple notes in their code, the tas3004 seems

+ * see this when for example recording stereo in
+ * audacity, or recording the tas output via cable
+ * on another machine (use a sinus generator or so).
+ * I tried programming the BiQuads but couldn't
+ * make the delay work, maybe someone can read the
+ * datasheet and fix it. The relevant Apple comment
+ * is in AppleTAS3004Audio.cpp lines 1637 ff. Note
+ * that their comment describing how they program
+ * the filters sucks...
+ *
+ * Other things:
+ * - this should actually register *two* aoa_codec
+ * structs since it has two inputs. Then it must
+ * use the prepare callback to forbid running the
+ * secondary output on a different clock.
+ * Also, whatever bus knows how to do this must
+ * provide two soundbus_dev devices and the fabric
+ * must be able to link them correctly.
+ *
+ * I don't even know if Apple ever uses the second
+ * port on the tas3004 though, I don't think their
+ * i2s controllers can even do it. OTOH, they all
+ * derive the clocks from common clocks, so it
+ * might just be possible. The framework allows the
+ * codec to refine the transfer_info items in the
+ * usable callback, so we can simply remove the
+ * rates the second instance is not using when it
+ * actually is in use.
+ * Maybe we'll need to make the sound busses have
+ * a 'clock group id' value so the codec can
+ * determine if the two outputs can be driven at
+ * the same time. But that is likely overkill, up
+ * to the fabric to not link them up incorrectly,
+ * and up to the hardware designer to not wire
+ * them up in some weird unusable way.
