-  <para>
-This document outlines the interface between the Linux scsi mid level
-and lower level drivers. Lower level drivers are variously called HBA
-(host bus adapter) drivers, host drivers (HD) or pseudo adapter drivers.
-The latter alludes to the fact that a lower level driver may be a
-bridge to another IO subsystem (and the "ide-scsi" driver is an example
-of this). There can be many lower level drivers active in a running
-system, but only one per hardware type. For example, the aic7xxx driver
-controls adaptec controllers based on the 7xxx chip series. Most lower
-level drivers can control one or more scsi hosts (a.k.a. scsi initiators).
-  </para>
-<para>
-This document can been found in an ASCII text file in the linux kernel 
-source: <filename>Documentation/scsi/scsi_mid_low_api.txt</filename> .
-It currently hold a little more information than this document. The
-<filename>drivers/scsi/hosts.h</filename> and <filename>
-drivers/scsi/scsi.h</filename> headers contain descriptions of members
-of important structures for the scsi subsystem.
-</para>
-  </chapter>
-  <chapter id="driver-struct">
-      <title>Driver structure</title>
-  <para>
-Traditionally a lower level driver for the scsi subsystem has been
-at least two files in the drivers/scsi directory. For example, a
-driver called "xyz" has a header file "xyz.h" and a source file
-"xyz.c". [Actually there is no good reason why this couldn't all
-be in one file.] Some drivers that have been ported to several operating
-systems (e.g. aic7xxx which has separate  files for generic and
-OS-specific code) have more than two files. Such drivers tend to have
-their own directory under the drivers/scsi directory.
-  </para>
-  <para>
-scsi_module.c is normally included at the end of a lower
-level driver. For it to work a declaration like this is needed before
-it is included:
-<programlisting>
-    static Scsi_Host_Template driver_template = DRIVER_TEMPLATE;
-    /* DRIVER_TEMPLATE should contain pointers to supported interface
-       functions. Scsi_Host_Template is defined hosts.h */
-    #include "scsi_module.c"
-</programlisting>
-  </para>
-  <para>
-The scsi_module.c assumes the name "driver_template" is appropriately
-defined. It contains 2 functions:
-<orderedlist>
-<listitem><para>
-     init_this_scsi_driver() called during builtin and module driver
-     initialization: invokes mid level's scsi_register_host()
-</para></listitem>
-<listitem><para>
-     exit_this_scsi_driver() called during closedown: invokes
-     mid level's scsi_unregister_host()
-</para></listitem>
-</orderedlist>
-  </para>
-<para>
-When a new, lower level driver is being added to Linux, the following 
-files (all found in the drivers/scsi directory) will need some attention: 
-Makefile, Config.help and Config.in . It is probably best to look at what 
-an existing lower level driver does in this regard.

-     <title>Locks</title>
-<para>
-Each Scsi_Host instance has a spin_lock called Scsi_Host::default_lock
-which is initialized in scsi_register() [found in hosts.c]. Within the
-same function the Scsi_Host::host_lock pointer is initialized to point
-at default_lock with the scsi_assign_lock() function. Thereafter
-lock and unlock operations performed by the mid level use the
-Scsi_Host::host_lock pointer.
-</para>
-<para>
-Lower level drivers can override the use of Scsi_Host::default_lock by
-using scsi_assign_lock(). The earliest opportunity to do this would
-be in the detect() function after it has invoked scsi_register(). It
-could be replaced by a coarser grain lock (e.g. per driver) or a
-lock of equal granularity (i.e. per host). Using finer grain locks
-(e.g. per scsi device) may be possible by juggling locks in
-queuecommand().

-  </chapter>
-  <chapter id="changes">
-     <title>Changes since lk 2.4 series</title>
-<para>
-io_request_lock has been replaced by several finer grained locks. The lock
-relevant to lower level drivers is Scsi_Host::host_lock and there is one
-per scsi host.
-</para>
-<para>
-The older error handling mechanism has been removed. This means the
-lower level interface functions abort() and reset() have been removed.
-</para>
-<para>
-In the 2.4 series the scsi subsystem configuration descriptions were
-aggregated with the configuration descriptions from all other Linux
-subsystems in the Documentation/Configure.help file. In the 2.5 series,
-the scsi subsystem now has its own (much smaller) drivers/scsi/Config.help

+The OpenIPMI driver supports the ability to put semi-custom and custom

+'Generate a panic event to all BMCs on a panic' option, you will get
+one event on a panic in a standard IPMI event format.  If you enable
+the 'Generate OEM events containing the panic string' option, you will
+also get a bunch of OEM events holding the panic string.
+The field settings of the events are:
+* Generator ID: 0x21 (kernel)
+* EvM Rev: 0x03 (this event is formatting in IPMI 1.0 format)
+* Sensor Type: 0x20 (OS critical stop sensor)
+* Sensor #: The first byte of the panic string (0 if no panic string)
+* Event Dir | Event Type: 0x6f (Assertion, sensor-specific event info)
+* Event Data 1: 0xa1 (Runtime stop in OEM bytes 2 and 3)
+* Event data 2: second byte of panic string
+* Event data 3: third byte of panic string
+See the IPMI spec for the details of the event layout.  This event is
+always sent to the local management controller.  It will handle routing
+the message to the right place
+Other OEM events have the following format:
+Record ID (bytes 0-1): Set by the SEL.
+Record type (byte 2): 0xf0 (OEM non-timestamped)
+byte 3: The slave address of the card saving the panic
+byte 4: A sequence number (starting at zero)
+The rest of the bytes (11 bytes) are the panic string.  If the panic string
+is longer than 11 bytes, multiple messages will be sent with increasing
+sequence numbers.
+Because you cannot send OEM events using the standard interface, this
+function will attempt to find an SEL and add the events there.  It
+will first query the capabilities of the local management controller.
+If it has an SEL, then they will be stored in the SEL of the local
+management controller.  If not, and the local management controller is
+an event generator, the event receiver from the local management
+controller will be queried and the events sent to the SEL on that
+device.  Otherwise, the events go nowhere since there is nowhere to
+send them.

+--------
+If the poweroff capability is selected, the IPMI driver will install

+is in the ipmi_poweroff module.  When the system requests a powerdown,

+3. Configuring cpufreq-stats
+1. Introduction
+cpufreq-stats is a driver that provices CPU frequency statistics for each CPU.
+This statistics is provided in /sysfs as a bunch of read_only interfaces. This
+interface (when configured) will appear in a seperate directory under cpufreq
+in /sysfs (<sysfs root>/devices/system/cpu/cpuX/cpufreq/stats/) for each CPU.
+Various statistics will form read_only files under this directory.
+This driver is designed to be independent of any particular cpufreq_driver
+that may be running on your CPU. So, it will work with any cpufreq_driver.
+2. Statistics Provided (with example)
+cpufreq stats provides following statistics (explained in detail below).
+-  time_in_state
+-  total_trans
+-  trans_table
+All the statistics will be from the time the stats driver has been inserted 
+to the time when a read of a particular statistic is done. Obviously, stats 
+driver will not have any information about the the frequcny transitions before
+the stats driver insertion.

+will mean this CPU spent <time> usertime units of time at <frequency>. Output
+will have one line for each of the supported freuencies. usertime units here

+Intel 830M/845G/852GM/855GM/865G/915G Framebuffer driver
+================================================================
+A. Introduction
+        This is a framebuffer driver for various Intel 810/815 compatible
+graphics devices.  These would include:
+        Intel 830M
+        Intel 810E845G
+        Intel 852GM
+        Intel 855GM
+        Intel 865G
+        Intel 915G
+B.  List of available options
+   a. "video=intelfb"
+        enables the intelfb driver
+        Recommendation: required
+   b. "mode=<xres>x<yres>[-<bpp>][@<refresh>]"
+        select mode
+        Recommendation: user preference
+        (default = 1024x768-32@70)
+   c. "vram=<value>"
+        select amount of system RAM in MB to allocate for the video memory
+        if not enough RAM was already allocated by the BIOS.
+        Recommendation: 1 - 4 MB.
+        (default = 4 MB)
+   d. "voffset=<value>"
+        select at what offset in MB of the logical memory to allocate the
+        framebuffer memory.  The intent is to avoid the memory blocks
+        used by standard graphics applications (XFree86). Depending on your
+        usage, adjust the value up or down, (0 for maximum usage, 63/127 MB
+        for the least amount).  Note, an arbitrary setting may conflict
+        with XFree86.
+        Recommendation: do not set
+        (default = 48 MB)
+   e. "accel"
+        enable text acceleration.  This can be enabled/reenabled anytime
+        by using 'fbset -accel true/false'.
+        Recommendation: enable
+        (default = set)
+   f. "hwcursor"
+        enable cursor acceleration.
+        Recommendation: enable
+        (default = set)
+   g. "mtrr"
+        enable MTRR.  This allows data transfers to the framebuffer memory
+        to occur in bursts which can significantly increase performance.
+        Not very helpful with the intel chips because of 'shared memory'.
+        Recommendation: set
+        (default = set)
+   h. "fixed"
+        disable mode switching.
+        Recommendation: do not set
+        (default = not set)
+   The binary parameters can be unset with a "no" prefix, example "noaccel".
+   The default parameter (not named) is the mode.
+C. Kernel booting
+Separate each option/option-pair by commas (,) and the option from its value
+with an equals sign (=) as in the following:
+video=i810fb:option1,option2=value2
+Sample Usage
+------------
+In /etc/lilo.conf, add the line:
+append="video=intelfb:800x600-32@75,accel,hwcursor,vram=8"
+This will initialize the framebuffer to 800x600 at 32bpp and 75Hz. The
+framebuffer will use 8 MB of System RAM. hw acceleration of text and cursor
+will be enabled.
+D.  Module options
+        The module parameters are essentially similar to the kernel
+parameters. The main difference is that you need to include a Boolean value
+(1 for TRUE, and 0 for FALSE) for those options which don't need a value.
+Example, to enable MTRR, include "mtrr=1".
+Sample Usage
+------------
+Using the same setup as described above, load the module like this:
+        modprobe intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1
+Or just add the following to /etc/modprobe.conf
+        options intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1
+and just do a
+        modprobe intelfb
+E.  Acknowledgment:
+        1.  Geert Uytterhoeven - his excellent howto and the virtual
+                                 framebuffer driver code made this possible.

+Execute-in-place for file mappings
+----------------------------------
+Motivation
+----------
+File mappings are performed by mapping page cache pages to userspace. In
+addition, read&write type file operations also transfer data from/to the page
+cache.
+For memory backed storage devices that use the block device interface, the page
+cache pages are in fact copies of the original storage. Various approaches
+exist to work around the need for an extra copy. The ramdisk driver for example
+does read the data into the page cache, keeps a reference, and discards the
+original data behind later on.
+Execute-in-place solves this issue the other way around: instead of keeping
+data in the page cache, the need to have a page cache copy is eliminated
+completely. With execute-in-place, read&write type operations are performed
+directly from/to the memory backed storage device. For file mappings, the
+storage device itself is mapped directly into userspace.
+This implementation was initialy written for shared memory segments between
+different virtual machines on s390 hardware to allow multiple machines to
+share the same binaries and libraries.
+Implementation
+--------------
+Execute-in-place is implemented in three steps: block device operation,
+address space operation, and file operations.
+A block device operation named direct_access is used to retrieve a
+reference (pointer) to a block on-disk. The reference is supposed to be
+cpu-addressable, physical address and remain valid until the release operation
+is performed. A struct block_device reference is used to address the device,
+and a sector_t argument is used to identify the individual block. As an
+alternative, memory technology devices can be used for this.
+The block device operation is optional, these block devices support it as of
+today:
+- dcssblk: s390 dcss block device driver
+An address space operation named get_xip_page is used to retrieve reference
+to a struct page. To address the target page, a reference to an address_space,
+and a sector number is provided. A 3rd argument indicates whether the
+function should allocate blocks if needed.
+This address space operation is mutually exclusive with readpage&writepage that
+do page cache read/write operations.
+The following filesystems support it as of today:
+- ext2: the second extended filesystem, see Documentation/filesystems/ext2.txt
+A set of file operations that do utilize get_xip_page can be found in
+mm/filemap_xip.c . The following file operation implementations are provided:
+- aio_read/aio_write
+- readv/writev
+- sendfile
+The generic file operations do_sync_read/do_sync_write can be used to implement
+classic synchronous IO calls.
+Shortcomings
+------------
+This implementation is limited to storage devices that are cpu addressable at
+all times (no highmem or such). It works well on rom/ram, but enhancements are
+needed to make it work with flash in read+write mode.
+Putting the Linux kernel and/or its modules on a xip filesystem does not mean
+they are not copied.

+Description
+-----------
+The chips supported by this driver are very similar. The Maxim MAX1617 is
+the oldest; it has the problem that it is not very well detectable. The
+MAX1617A solves that. The ADM1021 is a straight clone of the MAX1617A.
+Ditto for the THMC10. From here on, we will refer to all these chips as
+ADM1021-clones.
+The ADM1021 and MAX1617A reports a die code, which is a sort of revision
+code. This can help us pinpoint problems; it is not very useful
+otherwise.
+ADM1021-clones implement two temperature sensors. One of them is internal,
+and measures the temperature of the chip itself; the other is external and
+is realised in the form of a transistor-like device. A special alarm
+indicates whether the remote sensor is connected.
+Each sensor has its own low and high limits. When they are crossed, the
+corresponding alarm is set and remains on as long as the temperature stays
+out of range. Temperatures are measured in degrees Celsius. Measurements
+are possible between -65 and +127 degrees, with a resolution of one degree.
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared!
+This driver only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values. It is possible to make
+ADM1021-clones do faster measurements, but there is really no good reason
+for that.
+Xeon support
+------------
+Some Xeon processors have real max1617, adm1021, or compatible chips
+within them, with two temperature sensors.
+Other Xeons have chips with only one sensor.
+If you have a Xeon, and the adm1021 module loads, and both temperatures
+appear valid, then things are good.
+If the adm1021 module doesn't load, you should try this:
+        modprobe adm1021 force_adm1021=BUS,ADDRESS
+        ADDRESS can only be 0x18, 0x1a, 0x29, 0x2b, 0x4c, or 0x4e.
+If you have dual Xeons you may have appear to have two separate
+adm1021-compatible chips, or two single-temperature sensors, at distinct
+addresses.

+Description
+-----------
+(This is from Analog Devices.) The ADM1025 is a complete system hardware
+monitor for microprocessor-based systems, providing measurement and limit
+comparison of various system parameters. Five voltage measurement inputs
+are provided, for monitoring +2.5V, +3.3V, +5V and +12V power supplies and
+the processor core voltage. The ADM1025 can monitor a sixth power-supply
+voltage by measuring its own VCC. One input (two pins) is dedicated to a
+remote temperature-sensing diode and an on-chip temperature sensor allows
+ambient temperature to be monitored.
+One specificity of this chip is that the pin 11 can be hardwired in two
+different manners. It can act as the +12V power-supply voltage analog
+input, or as the a fifth digital entry for the VID reading (bit 4). It's
+kind of strange since both are useful, and the reason for designing the
+chip that way is obscure at least to me. The bit 5 of the configuration
+register can be used to define how the chip is hardwired. Please note that
+it is not a choice you have to make as the user. The choice was already
+made by your motherboard's maker. If the configuration bit isn't set
+properly, you'll have a wrong +12V reading or a wrong VID reading. The way
+the driver handles that is to preserve this bit through the initialization
+process, assuming that the BIOS set it up properly beforehand. If it turns
+out not to be true in some cases, we'll provide a module parameter to force
+modes.
+This driver also supports the ADM1025A, which differs from the ADM1025
+only in that it has "open-drain VID inputs while the ADM1025 has on-chip
+100k pull-ups on the VID inputs". It doesn't make any difference for us.

+Description
+-----------
+This driver implements support for the Analog Devices ADM1026. Analog
+Devices calls it a "complete thermal system management controller."
+The ADM1026 implements three (3) temperature sensors, 17 voltage sensors,
+16 general purpose digital I/O lines, eight (8) fan speed sensors (8-bit),
+an analog output and a PWM output along with limit, alarm and mask bits for
+all of the above. There is even 8k bytes of EEPROM memory on chip.
+Temperatures are measured in degrees Celsius. There are two external
+sensor inputs and one internal sensor. Each sensor has a high and low
+limit. If the limit is exceeded, an interrupt (#SMBALERT) can be
+generated. The interrupts can be masked. In addition, there are over-temp
+limits for each sensor. If this limit is exceeded, the #THERM output will
+be asserted. The current temperature and limits have a resolution of 1
+degree.
+Fan rotation speeds are reported in RPM (rotations per minute) but measured
+in counts of a 22.5kHz internal clock. Each fan has a high limit which
+corresponds to a minimum fan speed. If the limit is exceeded, an interrupt
+can be generated. Each fan can be programmed to divide the reference clock
+by 1, 2, 4 or 8. Not all RPM values can accurately be represented, so some
+rounding is done. With a divider of 8, the slowest measurable speed of a
+two pulse per revolution fan is 661 RPM.
+There are 17 voltage sensors. An alarm is triggered if the voltage has
+crossed a programmable minimum or maximum limit. Note that minimum in this
+case always means 'closest to zero'; this is important for negative voltage
+measurements. Several inputs have integrated attenuators so they can measure
+higher voltages directly. 3.3V, 5V, 12V, -12V and battery voltage all have
+dedicated inputs. There are several inputs scaled to 0-3V full-scale range
+for SCSI terminator power. The remaining inputs are not scaled and have
+a 0-2.5V full-scale range. A 2.5V or 1.82V reference voltage is provided
+for negative voltage measurements.
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 2.0
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+The ADM1026 measures continuously. Analog inputs are measured about 4
+times a second. Fan speed measurement time depends on fan speed and
+divisor. It can take as long as 1.5 seconds to measure all fan speeds.
+The ADM1026 has the ability to automatically control fan speed based on the
+temperature sensor inputs. Both the PWM output and the DAC output can be
+used to control fan speed. Usually only one of these two outputs will be
+used. Write the minimum PWM or DAC value to the appropriate control
+register. Then set the low temperature limit in the tmin values for each
+temperature sensor. The range of control is fixed at 20 �C, and the
+largest difference between current and tmin of the temperature sensors sets
+the control output. See the datasheet for several example circuits for
+controlling fan speed with the PWM and DAC outputs. The fan speed sensors
+do not have PWM compensation, so it is probably best to control the fan
+voltage from the power lead rather than on the ground lead.
+The datasheet shows an example application with VID signals attached to
+GPIO lines. Unfortunately, the chip may not be connected to the VID lines
+in this way. The driver assumes that the chips *is* connected this way to
+get a VID voltage.

+Interface
+---------
+The I2C addresses listed above assume BIOS has not changed the
+chip MSB 5-bit address. Each chip reports a unique manufacturer
+identification code as well as the chip revision/stepping level.
+Description
+-----------
+[From ADM9240] The ADM9240 is a complete system hardware monitor for
+microprocessor-based systems, providing measurement and limit comparison
+of up to four power supplies and two processor core voltages, plus
+temperature, two fan speeds and chassis intrusion. Measured values can
+be read out via an I2C-compatible serial System Management Bus, and values
+for limit comparisons can be programmed in over the same serial bus. The
+high speed successive approximation ADC allows frequent sampling of all
+analog channels to ensure a fast interrupt response to any out-of-limit
+measurement.
+The ADM9240, DS1780 and LM81 are register compatible, the following
+details are common to the three chips. Chip differences are described
+after this section.
+Measurements
+------------
+The measurement cycle
+The adm9240 driver will take a measurement reading no faster than once
+each two seconds. User-space may read sysfs interface faster than the
+measurement update rate and will receive cached data from the most
+recent measurement.
+ADM9240 has a very fast 320us temperature and voltage measurement cycle
+with independent fan speed measurement cycles counting alternating rising
+edges of the fan tacho inputs.
+DS1780 measurement cycle is about once per second including fan speed.
+LM81 measurement cycle is about once per 400ms including fan speed.
+The LM81 12-bit extended temperature measurement mode is not supported.
+Temperature
+-----------
+On chip temperature is reported as degrees Celsius as 9-bit signed data
+with resolution of 0.5 degrees Celsius. High and low temperature limits
+are 8-bit signed data with resolution of one degree Celsius.
+Temperature alarm is asserted once the temperature exceeds the high limit,
+and is cleared when the temperature falls below the temp1_max_hyst value.
+Fan Speed
+---------
+Two fan tacho inputs are provided, the ADM9240 gates an internal 22.5kHz
+clock via a divider to an 8-bit counter. Fan speed (rpm) is calculated by:
+rpm = (22500 * 60) / (count * divider)
+Automatic fan clock divider
+  * User sets 0 to fan_min limit
+    - low speed alarm is disabled
+    - fan clock divider not changed
+    - auto fan clock adjuster enabled for valid fan speed reading
+  * User sets fan_min limit too low
+    - low speed alarm is enabled
+    - fan clock divider set to max
+    - fan_min set to register value 254 which corresponds
+      to 664 rpm on adm9240
+    - low speed alarm will be asserted if fan speed is
+      less than minimum measurable speed
+    - auto fan clock adjuster disabled
+  * User sets reasonable fan speed
+    - low speed alarm is enabled
+    - fan clock divider set to suit fan_min
+    - auto fan clock adjuster enabled: adjusts fan_min
+  * User sets unreasonably high low fan speed limit
+    - resolution of the low speed limit may be reduced
+    - alarm will be asserted
+    - auto fan clock adjuster enabled: adjusts fan_min
+    * fan speed may be displayed as zero until the auto fan clock divider
+      adjuster brings fan speed clock divider back into chip measurement
+      range, this will occur within a few measurement cycles.
+Analog Output
+-------------
+An analog output provides a 0 to 1.25 volt signal intended for an external
+fan speed amplifier circuit. The analog output is set to maximum value on
+power up or reset. This doesn't do much on the test Intel SE440BX-2.
+Voltage Monitor
+Voltage (IN) measurement is internally scaled:
+    nr  label       nominal     maximum   resolution
+                      mV          mV         mV
+    0   +2.5V        2500        3320       13.0
+    1   Vccp1        2700        3600       14.1
+    2   +3.3V        3300        4380       17.2
+    3     +5V        5000        6640       26.0
+    4    +12V       12000       15940       62.5
+    5   Vccp2        2700        3600       14.1
+The reading is an unsigned 8-bit value, nominal voltage measurement is
+represented by a reading of 192, being 3/4 of the measurement range.
+An alarm is asserted for any voltage going below or above the set limits.
+The driver reports and accepts voltage limits scaled to the above table.
+VID Monitor
+-----------
+The chip has five inputs to read the 5-bit VID and reports the mV value
+based on detected CPU type.
+Chassis Intrusion
+-----------------
+An alarm is asserted when the CI pin goes active high. The ADM9240
+Datasheet has an example of an external temperature sensor driving
+this pin. On an Intel SE440BX-2 the Chassis Intrusion header is
+connected to a normally open switch.
+The ADM9240 provides an internal open drain on this line, and may output
+a 20 ms active low pulse to reset an external Chassis Intrusion latch.
+Clear the CI latch by writing value 1 to the sysfs chassis_clear file.
+Alarm flags reported as 16-bit word
+    bit     label               comment
+    ---     -------------       --------------------------
+     0      +2.5 V_Error        high or low limit exceeded
+     1      VCCP_Error          high or low limit exceeded
+     2      +3.3 V_Error        high or low limit exceeded
+     3      +5 V_Error          high or low limit exceeded
+     4      Temp_Error          temperature error
+     6      FAN1_Error          fan low limit exceeded
+     7      FAN2_Error          fan low limit exceeded
+     8      +12 V_Error         high or low limit exceeded
+     9      VCCP2_Error         high or low limit exceeded
+    12      Chassis_Error       CI pin went high
+Remaining bits are reserved and thus undefined. It is important to note
+that alarm bits may be cleared on read, user-space may latch alarms and
+provide the end-user with a method to clear alarm memory.

+Author: Mark M. Hoffman <mhoffman@lightlink.com>
+Description
+-----------
+This driver implements support for the Asus ASB100 and ASB100-A "Bach".
+These are custom ASICs available only on Asus mainboards. Asus refuses to
+supply a datasheet for these chips. Thanks go to many people who helped
+investigate their hardware, including:
+Vitaly V. Bursov
+Alexander van Kaam (author of MBM for Windows)
+Bertrik Sikken
+The ASB100 implements seven voltage sensors, three fan rotation speed
+sensors, four temperature sensors, VID lines and alarms. In addition to
+these, the ASB100-A also implements a single PWM controller for fans 2 and
+3 (i.e. one setting controls both.) If you have a plain ASB100, the PWM
+controller will simply not work (or maybe it will for you... it doesn't for
+me).
+Temperatures are measured and reported in degrees Celsius.
+Fan speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit.
+Voltage sensors (also known as IN sensors) report values in volts.
+The VID lines encode the core voltage value: the voltage level your
+processor should work with. This is hardcoded by the mainboard and/or
+processor itself. It is a value in volts.
+Alarms: (TODO question marks indicate may or may not work)
+0x0001 => in0 (?)
+0x0002 => in1 (?)
+0x0004 => in2
+0x0008 => in3

+0x0400 => in6 (?) (2)
+0x0800 => fan3
+0x1000 => chassis switch
+0x2000 => temp3
+Alarm Notes:
+(1) This alarm will only trigger if the hysteresis value is 127C.
+I.e. it behaves the same as w83781d.
+(2) The min and max registers for these values appear to
+be read-only or otherwise stuck at 0x00.
+TODO:
+* Experiment with fan divisors > 8.
+* Experiment with temp. sensor types.
+* Are there really 13 voltage inputs? Probably not...
+* Cleanups, no doubt...

+Module Parameters
+------------------
+* polarity int
+  Output's polarity: 0 = active high, 1 = active low
+Description
+-----------
+The DS1621 is a (one instance) digital thermometer and thermostat. It has
+both high and low temperature limits which can be user defined (i.e.
+programmed into non-volatile on-chip registers). Temperature range is -55
+degree Celsius to +125 in 0.5 increments. You may convert this into a
+Fahrenheit range of -67 to +257 degrees with 0.9 steps. If polarity
+parameter is not provided, original value is used.
+As for the thermostat, behavior can also be programmed using the polarity
+toggle. On the one hand ("heater"), the thermostat output of the chip,
+Tout, will trigger when the low limit temperature is met or underrun and
+stays high until the high limit is met or exceeded. On the other hand
+("cooler"), vice versa. That way "heater" equals "active low", whereas
+"conditioner" equals "active high". Please note that the DS1621 data sheet
+is somewhat misleading in this point since setting the polarity bit does
+not simply invert Tout.
+A second thing is that, during extensive testing, Tout showed a tolerance
+of up to +/- 0.5 degrees even when compared against precise temperature
+readings. Be sure to have a high vs. low temperature limit gap of al least
+1.0 degree Celsius to avoid Tout "bouncing", though!
+As for alarms, you can read the alarm status of the DS1621 via the 'alarms'
+/sys file interface. The result consists mainly of bit 6 and 5 of the
+configuration register of the chip; bit 6 (0x40 or 64) is the high alarm
+bit and bit 5 (0x20 or 32) the low one. These bits are set when the high or
+low limits are met or exceeded and are reset by the module as soon as the
+respective temperature ranges are left.
+The alarm registers are in no way suitable to find out about the actual
+status of Tout. They will only tell you about its history, whether or not
+any of the limits have ever been met or exceeded since last power-up or
+reset. Be aware: When testing, it showed that the status of Tout can change
+with neither of the alarms set.
+Temperature conversion of the DS1621 takes up to 1000ms; internal access to
+non-volatile registers may last for 10ms or below.
+High Accuracy Temperature Reading
+---------------------------------
+As said before, the temperature issued via the 9-bit i2c-bus data is
+somewhat arbitrary. Internally, the temperature conversion is of a
+different kind that is explained (not so...) well in the DS1621 data sheet.
+To cut the long story short: Inside the DS1621 there are two oscillators,
+both of them biassed by a temperature coefficient.
+Higher resolution of the temperature reading can be achieved using the
+internal projection, which means taking account of REG_COUNT and REG_SLOPE
+(the driver manages them):
+Taken from Dallas Semiconductors App Note 068: 'Increasing Temperature
+Resolution on the DS1620' and App Note 105: 'High Resolution Temperature
+Measurement with Dallas Direct-to-Digital Temperature Sensors'
+- Read the 9-bit temperature and strip the LSB (Truncate the .5 degs)
+- The resulting value is TEMP_READ.
+- Then, read REG_COUNT.
+- And then, REG_SLOPE.
+      TEMP = TEMP_READ - 0.25 + ((REG_SLOPE - REG_COUNT) / REG_SLOPE)
+Note that this is what the DONE bit in the DS1621 configuration register is
+good for: Internally, one temperature conversion takes up to 1000ms. Before
+that conversion is complete you will not be able to read valid things out
+of REG_COUNT and REG_SLOPE. The DONE bit, as you may have guessed by now,
+tells you whether the conversion is complete ("done", in plain English) and
+thus, whether the values you read are good or not.
+The DS1621 has two modes of operation: "Continuous" conversion, which can
+be understood as the default stand-alone mode where the chip gets the
+temperature and controls external devices via its Tout pin or tells other
+i2c's about it if they care. The other mode is called "1SHOT", that means
+that it only figures out about the temperature when it is explicitly told
+to do so; this can be seen as power saving mode.
+Now if you want to read REG_COUNT and REG_SLOPE, you have to either stop
+the continuous conversions until the contents of these registers are valid,
+or, in 1SHOT mode, you have to have one conversion made.

+Description
+-----------
+This is a simple EEPROM module meant to enable reading the first 256 bytes
+of an EEPROM (on a SDRAM DIMM for example). However, it will access serial
+EEPROMs on any I2C adapter. The supported devices are generically called
+24Cxx, and are listed above; however the numbering for these
+industry-standard devices may vary by manufacturer.
+This module was a programming exercise to get used to the new project
+organization laid out by Frodo, but it should be at least completely
+effective for decoding the contents of EEPROMs on DIMMs.
+DIMMS will typically contain a 24C01A or 24C02, or the 34C02 variants.
+The other devices will not be found on a DIMM because they respond to more
+than one address.
+DDC Monitors may contain any device. Often a 24C01, which responds to all 8
+addresses, is found.
+Recent Sony Vaio laptops have an EEPROM at 0x57. We couldn't get the
+specification, so it is guess work and far from being complete.
+The Microchip 24AA52/24LCS52, ST M34C02, and others support an additional
+software write protect register at 0x30 - 0x37 (0x20 less than the memory
+location). The chip responds to "write quick" detection at this address but
+does not respond to byte reads. If this register is present, the lower 128
+bytes of the memory array are not write protected. Any byte data write to
+this address will write protect the memory array permanently, and the
+device will no longer respond at the 0x30-37 address. The eeprom driver
+does not support this register.
+Lacking functionality:
+* Full support for larger devices (24C04, 24C08, 24C16). These are not
+typically found on a PC. These devices will appear as separate devices at
+multiple addresses.
+* Support for really large devices (24C32, 24C64, 24C128, 24C256, 24C512).
+These devices require two-byte address fields and are not supported.
+* Enable Writing. Again, no technical reason why not, but making it easy
+to change the contents of the EEPROMs (on DIMMs anyway) also makes it easy
+to disable the DIMMs (potentially preventing the computer from booting)
+until the values are restored somehow.
+Use:
+After inserting the module (and any other required SMBus/i2c modules), you
+should have some EEPROM directories in /sys/bus/i2c/devices/* of names such
+as "0-0050". Inside each of these is a series of files, the eeprom file
+contains the binary data from EEPROM.

+Kernel driver fscher
+====================

+        from Hermann Jung <hej@odn.de>,

+Description
+-----------
+This driver implements support for the Fujitsu-Siemens Hermes chip. It is
+described in the 'Register Set Specification BMC Hermes based Systemboard'
+from Fujitsu-Siemens.
+The Hermes chip implements a hardware-based system management, e.g. for
+controlling fan speed and core voltage. There is also a watchdog counter on
+the chip which can trigger an alarm and even shut the system down.
+The chip provides three temperature values (CPU, motherboard and
+auxiliary), three voltage values (+12V, +5V and battery) and three fans
+(power supply, CPU and auxiliary).
+Temperatures are measured in degrees Celsius. The resolution is 1 degree.
+Fan rotation speeds are reported in RPM (rotations per minute). The value
+can be divided by a programmable divider (1, 2 or 4) which is stored on
+the chip.
+Voltage sensors (also known as "in" sensors) report their values in volts.
+All values are reported as final values from the driver. There is no need
+for further calculations.
+Detailed description
+--------------------
+Below you'll find a single line description of all the bit values. With
+this information, you're able to decode e. g. alarms, wdog, etc. To make
+use of the watchdog, you'll need to set the watchdog time and enable the
+watchdog. After that it is necessary to restart the watchdog time within
+the specified period of time, or a system reset will occur.

+Limitations
+-----------
+* Measuring fan speed
+It seems that the chip counts "ripples" (typical fans produce 2 ripples per
+rotation while VERAX fans produce 18) in a 9-bit register. This register is
+read out every second, then the ripple prescaler (2, 4 or 8) is applied and
+the result is stored in the 8 bit output register. Due to the limitation of
+the counting register to 9 bits, it is impossible to measure a VERAX fan
+properly (even with a prescaler of 8). At its maximum speed of 3500 RPM the
+fan produces 1080 ripples per second which causes the counting register to
+overflow twice, leading to only 186 RPM.
+* Measuring input voltages
+in2 ("battery") reports the voltage of the onboard lithium battery and not
+3.3V from the power supply.
+* Undocumented features
+Fujitsu-Siemens Computers has not documented all features of the chip so
+far. Their software, System Guard, shows that there are a still some
+features which cannot be controlled by this implementation.

+Description
+-----------
+IMPORTANT:
+For the revision 0x00 chip, the in0, in1, and in2  values (+5V, +3V,
+and +12V) CANNOT be read. This is a limitation of the chip, not the driver.
+This driver supports the Genesys Logic GL518SM chip. There are at least
+two revision of this chip, which we call revision 0x00 and 0x80. Revision
+0x80 chips support the reading of all voltages and revision 0x00 only
+for VIN3.
+The GL518SM implements one temperature sensor, two fan rotation speed
+sensors, and four voltage sensors. It can report alarms through the
+computer speakers.
+Temperatures are measured in degrees Celsius. An alarm goes off while the
+temperature is above the over temperature limit, and has not yet dropped
+below the hysteresis limit. The alarm always reflects the current
+situation. Measurements are guaranteed between -10 degrees and +110
+degrees, with a accuracy of +/-3 degrees.
+Rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. In
+case when you have selected to turn fan1 off, no fan1 alarm is triggered.
+Fan readings can be divided by a programmable divider (1, 2, 4 or 8) to
+give the readings more range or accuracy.  Not all RPM values can
+accurately be represented, so some rounding is done. With a divider
+of 2, the lowest representable value is around 1900 RPM.
+Voltage sensors (also known as VIN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. The VDD input
+measures voltages between 0.000 and 5.865 volt, with a resolution of 0.023
+volt. The other inputs measure voltages between 0.000 and 4.845 volt, with
+a resolution of 0.019 volt. Note that revision 0x00 chips do not support
+reading the current voltage of any input except for VIN3; limit setting and
+alarms work fine, though.
+When an alarm is triggered, 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.
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once (except for temperature alarms). This means that the
+cause for the alarm may already have disappeared! Note that in the current
+implementation, all hardware registers are read whenever any data is read
+(unless it is less than 1.5 seconds since the last update). This means that
+you can easily miss once-only alarms.
+The GL518SM only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.

+Description
+-----------
+This driver implements support for the IT8705F, IT8712F and SiS950 chips.
+This driver also supports IT8712F, which adds SMBus access, and a VID
+input, used to report the Vcore voltage of the Pentium processor.
+The IT8712F additionally features VID inputs.
+These chips are 'Super I/O chips', supporting floppy disks, infrared ports,
+joysticks and other miscellaneous stuff. For hardware monitoring, they
+include an 'environment controller' with 3 temperature sensors, 3 fan
+rotation speed sensors, 8 voltage sensors, and associated alarms.
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the Overtemperature Shutdown limit is crossed.
+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 or 8) to give the
+readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+Voltage sensors (also known as IN sensors) report their values in volts. An
+alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution of
+0.016 volt. The battery voltage in8 does not have limit registers.
+The VID lines (IT8712F only) encode the core voltage value: the voltage
+level your processor should work with. This is hardcoded by the mainboard
+and/or processor itself. It is a value in volts.
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 1.5
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+The IT87xx only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+To change sensor N to a thermistor, 'echo 2 > tempN_type' where N is 1, 2,
+or 3. To change sensor N to a thermal diode, 'echo 3 > tempN_type'.
+Give 0 for unused sensor. Any other value is invalid. To configure this at
+startup, consult lm_sensors's /etc/sensors.conf. (2 = thermistor;
+3 = thermal diode)
+The fan speed control features are limited to manual PWM mode. Automatic
+"Smart Guardian" mode control handling is not implemented. However
+if you want to go for "manual mode" just write 1 to pwmN_enable.

+Supported chips:

+               http://www.national.com/pf/LM/LM63.html

+Thanks go to Tyan and especially Alex Buckingham for setting up a remote

+  http://www.tyan.com/
+Description
+-----------
+The LM63 is a digital temperature sensor with integrated fan monitoring
+and control.
+The LM63 is basically an LM86 with fan speed monitoring and control
+capabilities added. It misses some of the LM86 features though:
+ - No low limit for local temperature.
+ - No critical limit for local temperature.
+ - Critical limit for remote temperature can be changed only once. We
+   will consider that the critical limit is read-only.
+The datasheet isn't very clear about what the tachometer reading is.
+An explanation from National Semiconductor: The two lower bits of the read
+value have to be masked out. The value is still 16 bit in width.
+All temperature values are given in degrees Celsius. Resolution is 1.0
+degree for the local temperature, 0.125 degree for the remote temperature.
+The fan speed is measured using a tachometer. Contrary to most chips which
+store the value in an 8-bit register and have a selectable clock divider
+to make sure that the result will fit in the register, the LM63 uses 16-bit
+value for measuring the speed of the fan. It can measure fan speeds down to
+83 RPM, at least in theory.
+Note that the pin used for fan monitoring is shared with an alert out
+function. Depending on how the board designer wanted to use the chip, fan
+speed monitoring will or will not be possible. The proper chip configuration
+is left to the BIOS, and the driver will blindly trust it.
+A PWM output can be used to control the speed of the fan. The LM63 has two
+PWM modes: manual and automatic. Automatic mode is not fully implemented yet
+(you cannot define your custom PWM/temperature curve), and mode change isn't
+supported either.
+The lm63 driver will not update its values more frequently than every
+second; reading them more often will do no harm, but will return 'old'
+values.

+Description
+-----------
+The LM75 implements one temperature sensor. Limits can be set through the
+Overtemperature Shutdown register and Hysteresis register. Each value can be
+set and read to half-degree accuracy.
+An alarm is issued (usually to a connected LM78) when the temperature
+gets higher then the Overtemperature Shutdown value; it stays on until
+the temperature falls below the Hysteresis value.
+All temperatures are in degrees Celsius, and are guaranteed within a
+range of -55 to +125 degrees.
+The LM75 only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+The LM75 is usually used in combination with LM78-like chips, to measure
+the temperature of the processor(s).
+The DS75, DS1775, MAX6625, and MAX6626 are supported as well.
+They are not distinguished from an LM75. While most of these chips
+have three additional bits of accuracy (12 vs. 9 for the LM75),
+the additional bits are not supported. Not only that, but these chips will
+not be detected if not in 9-bit precision mode (use the force parameter if
+needed).
+The TCN75 is supported as well, and is not distinguished from an LM75.
+The LM75 is essentially an industry standard; there may be other
+LM75 clones not listed here, with or without various enhancements,
+that are supported.
+The LM77 is not supported, contrary to what we pretended for a long time.
+Both chips are simply not compatible, value encoding differs.

+Description
+-----------
+This driver implements support for the National Semiconductor LM78, LM78-J
+and LM79. They are described as 'Microprocessor System Hardware Monitors'.
+There is almost no difference between the three supported chips. Functionally,
+the LM78 and LM78-J are exactly identical. The LM79 has one more VID line,
+which is used to report the lower voltages newer Pentium processors use.
+From here on, LM7* means either of these three types.
+The LM7* implements one temperature sensor, three fan rotation speed sensors,
+seven voltage sensors, VID lines, alarms, and some miscellaneous stuff.
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the Overtemperature Shutdown limit is crossed; it is triggered again
+as soon as it drops below the Hysteresis value. A more useful behavior
+can be found by setting the Hysteresis value to +127 degrees Celsius; in
+this case, alarms are issued during all the time when the actual temperature
+is above the Overtemperature Shutdown value. Measurements are guaranteed
+between -55 and +125 degrees, with a resolution of 1 degree.
+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 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution
+of 0.016 volt.
+The VID lines encode the core voltage value: the voltage level your processor
+should work with. This is hardcoded by the mainboard and/or processor itself.
+It is a value in volts. When it is unconnected, you will often find the
+value 3.50 V here.
+In addition to the alarms described above, there are a couple of additional
+ones. There is a BTI alarm, which gets triggered when an external chip has
+crossed its limits. Usually, this is connected to all LM75 chips; if at
+least one crosses its limits, this bit gets set. The CHAS alarm triggers
+if your computer case is open. The FIFO alarms should never trigger; it
+indicates an internal error. The SMI_IN alarm indicates some other chip
+has triggered an SMI interrupt. As we do not use SMI interrupts at all,
+this condition usually indicates there is a problem with some other
+device.
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.
+The LM7* only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.

+Description
+-----------
+The LM83 is a digital temperature sensor. It senses its own temperature as
+well as the temperature of up to three external diodes. It is compatible
+with many other devices such as the LM84 and all other ADM1021 clones.
+The main difference between the LM83 and the LM84 in that the later can
+only sense the temperature of one external diode.
+Using the adm1021 driver for a LM83 should work, but only two temperatures
+will be reported instead of four.
+The LM83 is only found on a handful of motherboards. Both a confirmed
+list and an unconfirmed list follow. If you can confirm or infirm the
+fact that any of these motherboards do actually have an LM83, please
+contact us. Note that the LM90 can easily be misdetected as a LM83.
+Confirmed motherboards:
+    SBS         P014
+Unconfirmed motherboards:
+    Gigabyte    GA-8IK1100
+    Iwill       MPX2
+    Soltek      SL-75DRV5
+The driver has been successfully tested by Magnus Forsstr�m, who I'd
+like to thank here. More testers will be of course welcome.
+The fact that the LM83 is only scarcely used can be easily explained.
+Most motherboards come with more than just temperature sensors for
+health monitoring. They also have voltage and fan rotation speed
+sensors. This means that temperature-only chips are usually used as
+secondary chips coupled with another chip such as an IT8705F or similar
+chip, which provides more features. Since systems usually need three
+temperature sensors (motherboard, processor, power supply) and primary
+chips provide some temperature sensors, the secondary chip, if needed,
+won't have to handle more than two temperatures. Thus, ADM1021 clones
+are sufficient, and there is no need for a four temperatures sensor
+chip such as the LM83. The only case where using an LM83 would make
+sense is on SMP systems, such as the above-mentioned Iwill MPX2,
+because you want an additional temperature sensor for each additional
+CPU.
+On the SBS P014, this is different, since the LM83 is the only hardware
+monitoring chipset. One temperature sensor is used for the motherboard
+(actually measuring the LM83's own temperature), one is used for the
+CPU. The two other sensors must be used to measure the temperature of
+two other points of the motherboard. We suspect these points to be the
+north and south bridges, but this couldn't be confirmed.
+All temperature values are given in degrees Celsius. Local temperature
+is given within a range of 0 to +85 degrees. Remote temperatures are
+given within a range of 0 to +125 degrees. Resolution is 1.0 degree,
+accuracy is guaranteed to 3.0 degrees (see the datasheet for more
+details).
+Each sensor has its own high limit, but the critical limit is common to
+all four sensors. There is no hysteresis mechanism as found on most
+recent temperature sensors.
+The lm83 driver will not update its values more frequently than every
+other second; reading them more often will do no harm, but will return
+'old' values.

+Description
+-----------
+This driver implements support for the National Semiconductor LM85 and
+compatible chips including the Analog Devices ADM1027, ADT7463 and
+SMSC EMC6D10x chips family.
+The LM85 uses the 2-wire interface compatible with the SMBUS 2.0
+specification. Using an analog to digital converter it measures three (3)
+temperatures and five (5) voltages. It has four (4) 16-bit counters for
+measuring fan speed. Five (5) digital inputs are provided for sampling the
+VID signals from the processor to the VRM. Lastly, there are three (3) PWM
+outputs that can be used to control fan speed.
+The voltage inputs have internal scaling resistors so that the following
+voltage can be measured without external resistors:
+  2.5V, 3.3V, 5V, 12V, and CPU core voltage (2.25V)
+The temperatures measured are one internal diode, and two remote diodes.
+Remote 1 is generally the CPU temperature. These inputs are designed to
+measure a thermal diode like the one in a Pentium 4 processor in a socket
+423 or socket 478 package. They can also measure temperature using a
+transistor like the 2N3904.
+A sophisticated control system for the PWM outputs is designed into the
+LM85 that allows fan speed to be adjusted automatically based on any of the
+three temperature sensors. Each PWM output is individually adjustable and
+programmable. Once configured, the LM85 will adjust the PWM outputs in
+response to the measured temperatures without further host intervention.
+This feature can also be disabled for manual control of the PWM's.
+Each of the measured inputs (voltage, temperature, fan speed) has
+corresponding high/low limit values. The LM85 will signal an ALARM if any
+measured value exceeds either limit.
+The LM85 samples all inputs continuously. The lm85 driver will not read
+the registers more often than once a second. Further, configuration data is
+only read once each 5 minutes. There is twice as much config data as
+measurements, so this would seem to be a worthwhile optimization.
+Special Features
+----------------
+The LM85 has four fan speed monitoring modes. The ADM1027 has only two.
+Both have special circuitry to compensate for PWM interactions with the
+TACH signal from the fans. The ADM1027 can be configured to measure the
+speed of a two wire fan, but the input conditioning circuitry is different
+for 3-wire and 2-wire mode. For this reason, the 2-wire fan modes are not
+exposed to user control. The BIOS should initialize them to the correct
+mode. If you've designed your own ADM1027, you'll have to modify the
+init_client function and add an insmod parameter to set this up.
+To smooth the response of fans to changes in temperature, the LM85 has an
+optional filter for smoothing temperatures. The ADM1027 has the same
+config option but uses it to rate limit the changes to fan speed instead.
+The ADM1027 and ADT7463 have a 10-bit ADC and can therefore measure
+temperatures with 0.25 degC resolution. They also provide an offset to the
+temperature readings that is automatically applied during measurement.
+This offset can be used to zero out any errors due to traces and placement.
+The documentation says that the offset is in 0.25 degC steps, but in
+initial testing of the ADM1027 it was 1.00 degC steps. Analog Devices has
+confirmed this "bug". The ADT7463 is reported to work as described in the
+documentation. The current lm85 driver does not show the offset register.
+The ADT7463 has a THERM asserted counter. This counter has a 22.76ms
+resolution and a range of 5.8 seconds. The driver implements a 32-bit
+accumulator of the counter value to extend the range to over a year. The
+counter will stay at it's max value until read.
+See the vendor datasheets for more information. There is application note
+from National (AN-1260) with some additional information about the LM85.
+The Analog Devices datasheet is very detailed and describes a procedure for
+determining an optimal configuration for the automatic PWM control.
+The SMSC EMC6D100 & EMC6D101 monitor external voltages, temperatures, and
+fan speeds. They use this monitoring capability to alert the system to out
+of limit conditions and can automatically control the speeds of multiple
+fans in a PC or embedded system. The EMC6D101, available in a 24-pin SSOP
+package, and the EMC6D100, available in a 28-pin SSOP package, are designed
+to be register compatible. The EMC6D100 offers all the features of the
+EMC6D101 plus additional voltage monitoring and system control features.
+Unfortunately it is not possible to distinguish between the package
+versions on register level so these additional voltage inputs may read
+zero. The EMC6D102 features addtional ADC bits thus extending precision
+of voltage and temperature channels.
+Hardware Configurations
+-----------------------
+The LM85 can be jumpered for 3 different SMBus addresses. There are
+no other hardware configuration options for the LM85.
+The lm85 driver detects both LM85B and LM85C revisions of the chip. See the
+datasheet for a complete description of the differences. Other than
+identifying the chip, the driver behaves no differently with regard to
+these two chips. The LM85B is recommended for new designs.
+The ADM1027 and ADT7463 chips have an optional SMBALERT output that can be
+used to signal the chipset in case a limit is exceeded or the temperature
+sensors fail. Individual sensor interrupts can be masked so they won't
+trigger SMBALERT. The SMBALERT output if configured replaces one of the other
+functions (PWM2 or IN0). This functionality is not implemented in current
+driver.
+The ADT7463 also has an optional THERM output/input which can be connected
+to the processor PROC_HOT output. If available, the autofan control
+dynamic Tmin feature can be enabled to keep the system temperature within
+spec (just?!) with the least possible fan noise.
+Configuration Notes
+-------------------
+Besides standard interfaces driver adds following:
+* Temperatures and Zones
+Each temperature sensor is associated with a Zone. There are three
+sensors and therefore three zones (# 1, 2 and 3). Each zone has the following
+temperature configuration points:
+* temp#_auto_temp_off - temperature below which fans should be off or spinning very low.
+* temp#_auto_temp_min - temperature over which fans start to spin.
+* temp#_auto_temp_max - temperature when fans spin at full speed.
+* temp#_auto_temp_crit - temperature when all fans will run full speed.
+* PWM Control
+There are three PWM outputs. The LM85 datasheet suggests that the
+pwm3 output control both fan3 and fan4. Each PWM can be individually
+configured and assigned to a zone for it's control value. Each PWM can be
+configured individually according to the following options.
+* pwm#_auto_pwm_min - this specifies the PWM value for temp#_auto_temp_off
+                      temperature. (PWM value from 0 to 255)
+* pwm#_auto_pwm_freq - select base frequency of PWM output. You can select
+                       in range of 10.0 to 94.0 Hz in .1 Hz units.
+                       (Values 100 to 940).
+The pwm#_auto_pwm_freq can be set to one of the following 8 values. Setting the
+frequency to a value not on this list, will result in the next higher frequency
+being selected. The actual device frequency may vary slightly from this
+specification as designed by the manufacturer. Consult the datasheet for more
+details. (PWM Frequency values:  100, 150, 230, 300, 380, 470, 620, 940)
+* pwm#_auto_pwm_minctl - this flags selects for temp#_auto_temp_off temperature
+                         the bahaviour of fans. Write 1 to let fans spinning at
+                         pwm#_auto_pwm_min or write 0 to let them off.
+NOTE: It has been reported that there is a bug in the LM85 that causes the flag
+to be associated with the zones not the PWMs. This contradicts all the
+published documentation. Setting pwm#_min_ctl in this case actually affects all
+PWMs controlled by zone '#'.
+* PWM Controlling Zone selection
+* pwm#_auto_channels - controls zone that is associated with PWM
+Configuration choices:
+   Value     Meaning
+  ------  ------------------------------------------------
+      1    Controlled by Zone 1
+      2    Controlled by Zone 2
+      3    Controlled by Zone 3
+     23    Controlled by higher temp of Zone 2 or 3
+    123    Controlled by highest temp of Zone 1, 2 or 3
+      0    PWM always 0%  (off)
+     -1    PWM always 100%  (full on)
+     -2    Manual control (write to 'pwm#' to set)
+The National LM85's have two vendor specific configuration
+features. Tach. mode and Spinup Control. For more details on these,
+see the LM85 datasheet or Application Note AN-1260.
+The Analog Devices ADM1027 has several vendor specific enhancements.
+The number of pulses-per-rev of the fans can be set, Tach monitoring
+can be optimized for PWM operation, and an offset can be applied to
+the temperatures to compensate for systemic errors in the
+measurements.
+In addition to the ADM1027 features, the ADT7463 also has Tmin control
+and THERM asserted counts. Automatic Tmin control acts to adjust the
+Tmin value to maintain the measured temperature sensor at a specified
+temperature. There isn't much documentation on this feature in the
+ADT7463 data sheet. This is not supported by current driver.

+Description
+-----------
+This driver implements support for the National Semiconductor LM87.
+The LM87 implements up to three temperature sensors, up to two fan
+rotation speed sensors, up to seven voltage sensors, alarms, and some
+miscellaneous stuff.
+Temperatures are measured in degrees Celsius. Each input has a high
+and low alarm settings. A high limit produces an alarm when the value
+goes above it, and an alarm is also produced when the value goes below
+the low limit.
+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 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+Voltage sensors (also known as IN sensors) report their values in
+volts. An alarm is triggered if the voltage has crossed a programmable
+minimum or maximum limit. Note that minimum in this case always means
+'closest to zero'; this is important for negative voltage measurements.
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.0 seconds since the last update). This means that you can easily
+miss once-only alarms.
+The lm87 driver only updates its values each 1.0 seconds; reading it more
+often will do no harm, but will return 'old' values.
+Hardware Configurations
+-----------------------
+The LM87 has four pins which can serve one of two possible functions,
+depending on the hardware configuration.
+Some functions share pins, so not all functions are available at the same
+time. Which are depends on the hardware setup. This driver assumes that
+the BIOS configured the chip correctly. In that respect, it differs from
+the original driver (from lm_sensors for Linux 2.4), which would force the
+LM87 to an arbitrary, compile-time chosen mode, regardless of the actual
+chipset wiring.
+For reference, here is the list of exclusive functions:
+ - in0+in5 (default) or temp3
+ - fan1 (default) or in6
+ - fan2 (default) or in7
+ - VID lines (default) or IRQ lines (not handled by this driver)

+Description
+-----------
+The LM90 is a digital temperature sensor. It senses its own temperature as
+well as the temperature of up to one external diode. It is compatible
+with many other devices such as the LM86, the LM89, the LM99, the ADM1032,
+the MAX6657, MAX6658 and the MAX6659 all of which are supported by this driver.
+Note that there is no easy way to differentiate between the last three
+variants. The extra address and features of the MAX6659 are not supported by
+this driver. Additionally, the ADT7461 is supported if found in ADM1032
+compatibility mode.
+The specificity of this family of chipsets over the ADM1021/LM84
+family is that it features critical limits with hysteresis, and an
+increased resolution of the remote temperature measurement.
+The different chipsets of the family are not strictly identical, although
+very similar. This driver doesn't handle any specific feature for now,
+but could if there ever was a need for it. For reference, here comes a
+non-exhaustive list of specific features:
+LM90:
+  * Filter and alert configuration register at 0xBF.
+  * ALERT is triggered by temperatures over critical limits.
+LM86 and LM89:
+  * Same as LM90
+  * Better external channel accuracy
+LM99:
+  * Same as LM89
+  * External temperature shifted by 16 degrees down
+ADM1032:
+  * Consecutive alert register at 0x22.
+  * Conversion averaging.
+  * Up to 64 conversions/s.
+  * ALERT is triggered by open remote sensor.
+ADT7461
+  * Extended temperature range (breaks compatibility)
+  * Lower resolution for remote temperature
+MAX6657 and MAX6658:
+  * Remote sensor type selection
+MAX6659
+  * Selectable address
+  * Second critical temperature limit
+  * Remote sensor type selection
+All temperature values are given in degrees Celsius. Resolution
+is 1.0 degree for the local temperature, 0.125 degree for the remote
+temperature.
+Each sensor has its own high and low limits, plus a critical limit.
+Additionally, there is a relative hysteresis value common to both critical
+values. To make life easier to user-space applications, two absolute values
+are exported, one for each channel, but these values are of course linked.
+Only the local hysteresis can be set from user-space, and the same delta
+applies to the remote hysteresis.
+The lm90 driver will not update its values more frequently than every
+other second; reading them more often will do no harm, but will return
+'old' values.

+Description
+-----------
+The National Semiconductor PC87360 Super I/O chip contains monitoring and
+PWM control circuitry for two fans. The PC87363 chip is similar, and the
+PC87364 chip has monitoring and PWM control for a third fan.
+The National Semiconductor PC87365 and PC87366 Super I/O chips are complete
+hardware monitoring chipsets, not only controlling and monitoring three fans,
+but also monitoring eleven voltage inputs and two (PC87365) or up to four
+(PC87366) temperatures.

+The driver assumes that no more than one chip is present, and one of the
+standard Super I/O addresses is used (0x2E/0x2F or 0x4E/0x4F)
+Fan Monitoring
+--------------
+Fan rotation speeds are reported in RPM (revolutions per minute). An alarm
+is triggered if the rotation speed has dropped below a programmable limit.
+A different alarm is triggered if the fan speed is too low to be measured.
+Fan readings are affected by a programmable clock divider, giving the
+readings more range or accuracy. Usually, users have to learn how it works,
+but this driver implements dynamic clock divider selection, so you don't
+have to care no more.
+For reference, here are a few values about clock dividers:
+                slowest         accuracy        highest
+                measurable      around 3000     accurate
+    divider     speed (RPM)     RPM (RPM)       speed (RPM)
+         1        1882              18           6928
+         2         941              37           4898
+         4         470              74           3464
+         8         235             150           2449
+For the curious, here is how the values above were computed:
+ * slowest measurable speed: clock/(255*divider)
+ * accuracy around 3000 RPM: 3000^2/clock
+ * highest accurate speed: sqrt(clock*100)
+The clock speed for the PC87360 family is 480 kHz. I arbitrarily chose 100
+RPM as the lowest acceptable accuracy.
+As mentioned above, you don't have to care about this no more.
+Note that not all RPM values can be represented, even when the best clock
+divider is selected. This is not only true for the measured speeds, but
+also for the programmable low limits, so don't be surprised if you try to
+set, say, fan1_min to 2900 and it finally reads 2909.
+Fan Control
+-----------
+PWM (pulse width modulation) values range from 0 to 255, with 0 meaning
+that the fan is stopped, and 255 meaning that the fan goes at full speed.
+Be extremely careful when changing PWM values. Low PWM values, even
+non-zero, can stop the fan, which may cause irreversible damage to your
+hardware if temperature increases too much. When changing PWM values, go
+step by step and keep an eye on temperatures.
+One user reported problems with PWM. Changing PWM values would break fan
+speed readings. No explanation nor fix could be found.
+Temperature Monitoring
+----------------------
+Temperatures are reported in degrees Celsius. Each temperature measured has
+associated low, high and overtemperature limits, each of which triggers an
+alarm when crossed.
+The first two temperature channels are external. The third one (PC87366
+only) is internal.
+The PC87366 has three additional temperature channels, based on
+thermistors (as opposed to thermal diodes for the first three temperature
+channels). For technical reasons, these channels are held by the VLM
+(voltage level monitor) logical device, not the TMS (temperature
+measurement) one. As a consequence, these temperatures are exported as
+voltages, and converted into temperatures in user-space.
+Note that these three additional channels share their pins with the
+external thermal diode channels, so you (physically) can't use them all at
+the same time. Although it should be possible to mix the two sensor types,
+the documents from National Semiconductor suggest that motherboard
+manufacturers should choose one type and stick to it. So you will more
+likely have either channels 1 to 3 (thermal diodes) or 3 to 6 (internal
+thermal diode, and thermistors).
+Voltage Monitoring
+------------------
+Voltages are reported relatively to a reference voltage, either internal or
+external. Some of them (in7:Vsb, in8:Vdd and in10:AVdd) are divided by two
+internally, you will have to compensate in sensors.conf. Others (in0 to in6)
+are likely to be divided externally. The meaning of each of these inputs as
+well as the values of the resistors used for division is left to the
+motherboard manufacturers, so you will have to document yourself and edit
+sensors.conf accordingly. National Semiconductor has a document with
+recommended resistor values for some voltages, but this still leaves much
+room for per motherboard specificities, unfortunately. Even worse,
+motherboard manufacturers don't seem to care about National Semiconductor's
+recommendations.
+Each voltage measured has associated low and high limits, each of which
+triggers an alarm when crossed.
+When available, VID inputs are used to provide the nominal CPU Core voltage.
+The driver will default to VRM 9.0, but this can be changed from user-space.
+The chipsets can handle two sets of VID inputs (on dual-CPU systems), but
+the driver will only export one for now. This may change later if there is
+a need.
+General Remarks
+---------------
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that all hardware registers are read whenever any
+data is read (unless it is less than 2 seconds since the last update, in
+which case cached values are returned instead). As a consequence, when
+a once-only alarm triggers, it may take 2 seconds for it to show, and 2
+more seconds for it to disappear.
+Monitoring of in9 isn't enabled at lower init levels (<3) because that
+channel measures the battery voltage (Vbat). It is a known fact that
+repeatedly sampling the battery voltage reduces its lifetime. National
+Semiconductor smartly designed their chipset so that in9 is sampled only
+once every 1024 sampling cycles (that is every 34 minutes at the default
+sampling rate), so the effect is attenuated, but still present.
+Limitations
+-----------
+The datasheets suggests that some values (fan mins, fan dividers)
+shouldn't be changed once the monitoring has started, but we ignore that
+recommendation. We'll reconsider if it actually causes trouble.

+Description
+-----------
+The PCF8574(A) is an 8-bit I/O expander for the I2C bus produced by Philips
+Semiconductors. It is designed to provide a byte I2C interface to up to 16
+separate devices (8 x PCF8574 and 8 x PCF8574A).
+This device consists of a quasi-bidirectional port. Each of the eight I/Os
+can be independently used as an input or output. To setup an I/O as an
+input, you have to write a 1 to the corresponding output.
+For more informations see the datasheet.
+Accessing PCF8574(A) via /sys interface
+-------------------------------------
+! Be careful !
+The PCF8574(A) is plainly impossible to detect ! Stupid chip.
+So every chip with address in the interval [20..27] and [38..3f] are
+detected as PCF8574(A). If you have other chips in this address
+range, the workaround is to load this module after the one
+for your others chips.
+On detection (i.e. insmod, modprobe et al.), directories are being
+created for each detected PCF8574(A):
+/sys/bus/i2c/devices/<0>-<1>/
+where <0> is the bus the chip was detected on (e. g. i2c-0)
+and <1> the chip address ([20..27] or [38..3f]):
+(example: /sys/bus/i2c/devices/1-0020/)
+Inside these directories, there are two files each:
+read and write (and one file with chip name).
+The read file is read-only. Reading gives you the current I/O input
+if the corresponding output is set as 1, otherwise the current output
+value, that is to say 0.
+The write file is read/write. Writing a value outputs it on the I/O
+port. Reading returns the last written value.
+On module initialization the chip is configured as eight inputs (all
+outputs to 1), so you can connect any circuit to the PCF8574(A) without
+being afraid of short-circuit.

+The PCF8591 has 4 analog inputs programmable as single-ended or
+differential inputs :
+- mode 0 : four single ended inputs
+        Pins AIN0 to AIN3 are single ended inputs for channels 0 to 3
+- mode 1 : three differential inputs
+        Pins AIN3 is the common negative differential input
+        Pins AIN0 to AIN2 are positive differential inputs for channels 0 to 2
+- mode 2 : single ended and differential mixed
+        Pins AIN0 and AIN1 are single ended inputs for channels 0 and 1
+        Pins AIN2 is the positive differential input for channel 3
+        Pins AIN3 is the negative differential input for channel 3
+- mode 3 : two differential inputs
+        Pins AIN0 is the positive differential input for channel 0
+        Pins AIN1 is the negative differential input for channel 0
+        Pins AIN2 is the positive differential input for channel 1
+        Pins AIN3 is the negative differential input for channel 1
+See the datasheet for details.
+Module parameters
+-----------------
+* input_mode int
+    Analog input mode:
+         0 = four single ended inputs
+         1 = three differential inputs
+         2 = single ended and differential mixed
+         3 = two differential inputs
+Accessing PCF8591 via /sys interface
+-------------------------------------
+! Be careful !
+The PCF8591 is plainly impossible to detect ! Stupid chip.
+So every chip with address in the interval [48..4f] is
+detected as PCF8591. If you have other chips in this address
+range, the workaround is to load this module after the one
+for your others chips.
+On detection (i.e. insmod, modprobe et al.), directories are being
+created for each detected PCF8591:
+/sys/bus/devices/<0>-<1>/
+where <0> is the bus the chip was detected on (e. g. i2c-0)
+and <1> the chip address ([48..4f])
+Inside these directories, there are such files:
+in0, in1, in2, in3, out0_enable, out0_output, name
+Name contains chip name.
+The in0, in1, in2 and in3 files are RO. Reading gives the value of the
+corresponding channel. Depending on the current analog inputs configuration,
+files in2 and/or in3 do not exist. Values range are from 0 to 255 for single
+ended inputs and -128 to +127 for differential inputs (8-bit ADC).
+The out0_enable file is RW. Reading gives "1" for analog output enabled and
+"0" for analog output disabled. Writing accepts "0" and "1" accordingly.
+The out0_output file is RW. Writing a number between 0 and 255 (8-bit DAC), send
+the value to the digital-to-analog converter. Note that a voltage will
+only appears on AOUT pin if aout0_enable equals 1. Reading returns the last
+value written.

+Description
+-----------
+The SiS5595 southbridge has integrated hardware monitor functions. It also
+has an I2C bus, but this driver only supports the hardware monitor. For the
+I2C bus driver see i2c-sis5595.
+The SiS5595 implements zero or one temperature sensor, two fan speed
+sensors, four or five voltage sensors, and alarms.
+On the first version of the chip, there are four voltage sensors and one
+temperature sensor.
+On the second version of the chip, the temperature sensor (temp) and the
+fifth voltage sensor (in4) share a pin which is configurable, but not
+through the driver. Sorry. The driver senses the configuration of the pin,
+which was hopefully set by the BIOS.
+Temperatures are measured in degrees Celsius. An alarm is triggered once
+when the max is crossed; it is also triggered when it drops below the min
+value. Measurements are guaranteed between -55 and +125 degrees, with a
+resolution of 1 degree.
+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 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+Voltage sensors (also known as IN sensors) report their values in volts. An
+alarm is triggered if the voltage has crossed a programmable minimum or
+maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution of
+0.016 volt.
+In addition to the alarms described above, there is a BTI alarm, which gets
+triggered when an external chip has crossed its limits. Usually, this is
+connected to some LM75-like chip; if at least one crosses its limits, this
+bit gets set.
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may already
+have disappeared! Note that in the current implementation, all hardware
+registers are read whenever any data is read (unless it is less than 1.5
+seconds since the last update). This means that you can easily miss
+once-only alarms.
+The SiS5595 only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+Problems
+--------
+Some chips refuse to be enabled. We don't know why.
+The driver will recognize this and print a message in dmesg.

+Description
+-----------
+This driver implements support for ISA accesses *only* for
+the Winbond W83627HF, W83627THF, W83697HF and W83637HF Super I/O chips.
+We will refer to them collectively as Winbond chips.
+This driver supports ISA accesses, which should be more reliable
+than i2c accesses. Also, for Tyan boards which contain both a
+Super I/O chip and a second i2c-only Winbond chip (often a W83782D),
+using this driver will avoid i2c address conflicts and complex
+initialization that were required in the w83781d driver.
+If you really want i2c accesses for these Super I/O chips,
+use the w83781d driver. However this is not the preferred method
+now that this ISA driver has been developed.
+Technically, the w83627thf does not support a VID reading. However, it's
+possible or even likely that your mainboard maker has routed these signals
+to a specific set of general purpose IO pins (the Asus P4C800-E is one such
+board). The w83627thf driver now interprets these as VID. If the VID on
+your board doesn't work, first see doc/vid in the lm_sensors package. If
+that still doesn't help, email us at lm-sensors@lm-sensors.org.
+For further information on this driver see the w83781d driver
+documentation.

+  (default 1)
+  Use 'init=0' to bypass initializing the chip.
+  Try this if your computer crashes when you load the module.
+force_subclients=bus,caddr,saddr,saddr
+  This is used to force the i2c addresses for subclients of

+  0x4a and 0x4b. This parameter is useful for certain Tyan boards.
+Description
+-----------
+This driver implements support for the Winbond W83781D, W83782D, W83783S,
+W83627HF chips, and the Asus AS99127F chips. We will refer to them
+collectively as W8378* chips.
+There is quite some difference between these chips, but they are similar
+enough that it was sensible to put them together in one driver.
+The W83627HF chip is assumed to be identical to the ISA W83782D.
+The Asus chips are similar to an I2C-only W83782D.

+Detection of these chips can sometimes be foiled because they can be in
+an internal state that allows no clean access. If you know the address
+of the chip, use a 'force' parameter; this will put them into a more
+well-behaved state first.
+The W8378* implements temperature sensors (three on the W83781D and W83782D,
+two on the W83783S), three fan rotation speed sensors, voltage sensors
+(seven on the W83781D, nine on the W83782D and six on the W83783S), VID
+lines, alarms with beep warnings, and some miscellaneous stuff.
+Temperatures are measured in degrees Celsius. There is always one main
+temperature sensor, and one (W83783S) or two (W83781D and W83782D) other
+sensors. An alarm is triggered for the main sensor once when the
+Overtemperature Shutdown limit is crossed; it is triggered again as soon as
+it drops below the Hysteresis value. A more useful behavior
+can be found by setting the Hysteresis value to +127 degrees Celsius; in
+this case, alarms are issued during all the time when the actual temperature
+is above the Overtemperature Shutdown value. The driver sets the
+hysteresis value for temp1 to 127 at initialization.
+For the other temperature sensor(s), an alarm is triggered when the
+temperature gets higher then the Overtemperature Shutdown value; it stays
+on until the temperature falls below the Hysteresis value. But on the
+W83781D, there is only one alarm that functions for both other sensors!
+Temperatures are guaranteed within a range of -55 to +125 degrees. The
+main temperature sensors has a resolution of 1 degree; the other sensor(s)
+of 0.5 degree.
+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 or 8 for the
+W83781D; 1, 2, 4, 8, 16, 32, 64 or 128 for the others) to give
+the readings more range or accuracy. Not all RPM values can accurately
+be represented, so some rounding is done. With a divider of 2, the lowest
+representable value is around 2600 RPM.
+Voltage sensors (also known as IN sensors) report their values in volts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit. Note that minimum in this case always means 'closest to
+zero'; this is important for negative voltage measurements. All voltage
+inputs can measure voltages between 0 and 4.08 volts, with a resolution
+of 0.016 volt.
+The VID lines encode the core voltage value: the voltage level your processor
+should work with. This is hardcoded by the mainboard and/or processor itself.
+It is a value in volts. When it is unconnected, you will often find the
+value 3.50 V here.
+The W83782D and W83783S temperature conversion machine understands about
+several kinds of temperature probes. You can program the so-called
+beta value in the sensor files. '1' is the PII/Celeron diode, '2' is the
+TN3904 transistor, and 3435 the default thermistor value. Other values
+are (not yet) supported.
+In addition to the alarms described above, there is a CHAS alarm on the
+chips which triggers if your computer case is open.
+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.
+If an alarm triggers, it will remain triggered until the hardware register
+is read at least once. This means that the cause for the alarm may
+already have disappeared! Note that in the current implementation, all
+hardware registers are read whenever any data is read (unless it is less
+than 1.5 seconds since the last update). This means that you can easily
+miss once-only alarms.
+The chips only update values each 1.5 seconds; reading them more often
+will do no harm, but will return 'old' values.
+AS99127F PROBLEMS
+-----------------
+The as99127f support was developed without the benefit of a datasheet.
+In most cases it is treated as a w83781d (although revision 2 of the
+AS99127F looks more like a w83782d).
+This support will be BETA until a datasheet is released.
+One user has reported problems with fans stopping
+occasionally.
+Note that the individual beep bits are inverted from the other chips.
+The driver now takes care of this so that user-space applications
+don't have to know about it.
+Known problems:
+        - Problems with diode/thermistor settings (supported?)
+        - One user reports fans stopping under high server load.
+        - Revision 2 seems to have 2 PWM registers but we don't know
+          how to handle them. More details below.
+These will not be fixed unless we get a datasheet.
+If you have problems, please lobby Asus to release a datasheet.
+Unfortunately several others have without success.
+Please do not send mail to us asking for better as99127f support.
+We have done the best we can without a datasheet.
+Please do not send mail to the author or the sensors group asking for
+a datasheet or ideas on how to convince Asus. We can't help.
+NOTES:
+-----
+  783s has no in1 so that in[2-6] are compatible with the 781d/782d.
+  783s pin is programmable for -5V or temp1; defaults to -5V,
+       no control in driver so temp1 doesn't work.
+  782d and 783s datasheets differ on which is pwm1 and which is pwm2.
+       We chose to follow 782d.
+  782d and 783s pin is programmable for fan3 input or pwm2 output;
+       defaults to fan3 input.
+       If pwm2 is enabled (with echo 255 1 > pwm2), then
+       fan3 will report 0.
+  782d has pwm1-2 for ISA, pwm1-4 for i2c. (pwm3-4 share pins with
+       the ISA pins)

+Asus Clones
+-----------
+We have no datasheets for the Asus clones (AS99127F and ASB100 Bach).
+Here are some very useful information that were given to us by Alex Van
+Kaam about how to detect these chips, and how to read their values. He
+also gives advice for another Asus chipset, the Mozart-2 (which we
+don't support yet). Thanks Alex!
+I reworded some parts and added personal comments.
+# Detection:
+AS99127F rev.1, AS99127F rev.2 and ASB100:
+- I2C address range: 0x29 - 0x2F
+- If register 0x58 holds 0x31 then we have an Asus (either ASB100 or
+  AS99127F)
+- Which one depends on register 0x4F (manufacturer ID):
+  0x06 or 0x94: ASB100
+  0x12 or 0xC3: AS99127F rev.1
+  0x5C or 0xA3: AS99127F rev.2
+  Note that 0x5CA3 is Winbond's ID (WEC), which let us think Asus get their
+  AS99127F rev.2 direct from Winbond. The other codes mean ATT and DVC,
+  respectively. ATT could stand for Asustek something (although it would be
+  very badly chosen IMHO), I don't know what DVC could stand for. Maybe
+  these codes simply aren't meant to be decoded that way.
+Mozart-2:
+- I2C address: 0x77
+- If register 0x58 holds 0x56 or 0x10 then we have a Mozart-2
+- Of the Mozart there are 3 types:
+  0x58=0x56, 0x4E=0x94, 0x4F=0x36: Asus ASM58 Mozart-2
+  0x58=0x56, 0x4E=0x94, 0x4F=0x06: Asus AS2K129R Mozart-2
+  0x58=0x10, 0x4E=0x5C, 0x4F=0xA3: Asus ??? Mozart-2
+  You can handle all 3 the exact same way :)
+# Temperature sensors:
+ASB100:
+- sensor 1: register 0x27
+- sensor 2 & 3 are the 2 LM75's on the SMBus
+- sensor 4: register 0x17
+Remark: I noticed that on Intel boards sensor 2 is used for the CPU
+  and 4 is ignored/stuck, on AMD boards sensor 4 is the CPU and sensor 2 is
+  either ignored or a socket temperature.
+AS99127F (rev.1 and 2 alike):
+- sensor 1: register 0x27
+- sensor 2 & 3 are the 2 LM75's on the SMBus
+Remark: Register 0x5b is suspected to be temperature type selector. Bit 1
+  would control temp1, bit 3 temp2 and bit 5 temp3.
+Mozart-2:
+- sensor 1: register 0x27
+- sensor 2: register 0x13
+# Fan sensors:
+ASB100, AS99127F (rev.1 and 2 alike):
+- 3 fans, identical to the W83781D
+Mozart-2:
+- 2 fans only, 1350000/RPM/div
+- fan 1: register 0x28,  divisor on register 0xA1 (bits 4-5)
+- fan 2: register 0x29,  divisor on register 0xA1 (bits 6-7)
+# Voltages:
+This is where there is a difference between AS99127F rev.1 and 2.
+Remark: The difference is similar to the difference between
+  W83781D and W83782D.
+ASB100:

+# PWM
+Additional info about PWM on the AS99127F (may apply to other Asus
+chips as well) by Jean Delvare as of 2004-04-09:
+AS99127F revision 2 seems to have two PWM registers at 0x59 and 0x5A,
+and a temperature sensor type selector at 0x5B (which basically means
+that they swapped registers 0x59 and 0x5B when you compare with Winbond
+chips).
+Revision 1 of the chip also has the temperature sensor type selector at
+0x5B, but PWM registers have no effect.
+We don't know exactly how the temperature sensor type selection works.
+Looks like bits 1-0 are for temp1, bits 3-2 for temp2 and bits 5-4 for
+temp3, although it is possible that only the most significant bit matters
+each time. So far, values other than 0 always broke the readings.
+PWM registers seem to be split in two parts: bit 7 is a mode selector,
+while the other bits seem to define a value or threshold.
+When bit 7 is clear, bits 6-0 seem to hold a threshold value. If the value
+is below a given limit, the fan runs at low speed. If the value is above
+the limit, the fan runs at full speed. We have no clue as to what the limit
+represents. Note that there seem to be some inertia in this mode, speed
+changes may need some time to trigger. Also, an hysteresis mechanism is
+suspected since walking through all the values increasingly and then
+decreasingly led to slightly different limits.
+When bit 7 is set, bits 3-0 seem to hold a threshold value, while bits 6-4
+would not be significant. If the value is below a given limit, the fan runs
+at full speed, while if it is above the limit it runs at low speed (so this
+is the contrary of the other mode, in a way). Here again, we don't know
+what the limit is supposed to represent.
+One remarkable thing is that the fans would only have two or three
+different speeds (transitional states left apart), not a whole range as
+you usually get with PWM.
+As a conclusion, you can write 0x00 or 0x8F to the PWM registers to make
+fans run at low speed, and 0x7F or 0x80 to make them run at full speed.
+Please contact us if you can figure out how it is supposed to work. As
+long as we don't know more, the w83781d driver doesn't handle PWM on
+AS99127F chips at all.
+Additional info about PWM on the AS99127F rev.1 by Hector Martin:
+I've been fiddling around with the (in)famous 0x59 register and
+found out the following values do work as a form of coarse pwm:
+0x80 - seems to turn fans off after some time(1-2 minutes)... might be
+some form of auto-fan-control based on temp? hmm (Qfan? this mobo is an
+old ASUS, it isn't marketed as Qfan. Maybe some beta pre-attemp at Qfan
+that was dropped at the BIOS)
+0x81 - off
+0x82 - slightly "on-ner" than off, but my fans do not get to move. I can
+hear the high-pitched PWM sound that motors give off at too-low-pwm.
+0x83 - now they do move. Estimate about 70% speed or so.
+0x84-0x8f - full on
+Changing the high nibble doesn't seem to do much except the high bit
+(0x80) must be set for PWM to work, else the current pwm doesn't seem to
+change.
+My mobo is an ASUS A7V266-E. This behavior is similar to what I got
+with speedfan under Windows, where 0-15% would be off, 15-2x% (can't
+remember the exact value) would be 70% and higher would be full on.

+Kernel driver w83l785ts
+=======================
+Supported chips:
+  * Winbond W83L785TS-S
+    Prefix: 'w83l785ts'
+    Addresses scanned: I2C 0x2e
+    Datasheet: Publicly available at the Winbond USA website
+               http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83L785TS-S.pdf
+Authors:
+        Jean Delvare <khali@linux-fr.org>
+Description
+-----------
+The W83L785TS-S is a digital temperature sensor. It senses the
+temperature of a single external diode. The high limit is
+theoretically defined as 85 or 100 degrees C through a combination
+of external resistors, so the user cannot change it. Values seen so
+far suggest that the two possible limits are actually 95 and 110
+degrees C. The datasheet is rather poor and obviously inaccurate
+on several points including this one.
+All temperature values are given in degrees Celsius. Resolution
+is 1.0 degree. See the datasheet for details.
+The w83l785ts driver will not update its values more frequently than
+every other second; reading them more often will do no harm, but will
+return 'old' values.
+Known Issues
+------------
+On some systems (Asus), the BIOS is known to interfere with the driver
+and cause read errors. The driver will retry a given number of times
+(5 by default) and then give up, returning the old value (or 0 if
+there is no old value). It seems to work well enough so that you should
+not notice anything. Thanks to James Bolt for helping test this feature.

+Introduction
+------------
+Most mainboards have sensor chips to monitor system health (like temperatures,
+voltages, fans speed). They are often connected through an I2C bus, but some
+are also connected directly through the ISA bus.
+The kernel drivers make the data from the sensor chips available in the /sys
+virtual filesystem. Userspace tools are then used to display or set or the
+data in a more friendly manner.
+Lm-sensors
+----------
+Core set of utilites that will allow you to obtain health information,
+setup monitoring limits etc. You can get them on their homepage
+http://www.lm-sensors.nu/ or as a package from your Linux distribution.
+If from website:
+Get lmsensors from project web site. Please note, you need only userspace
+part, so compile with "make user_install" target.
+General hints to get things working:
+0) get lm-sensors userspace utils
+1) compile all drivers in I2C section as modules in your kernel
+2) run sensors-detect script, it will tell you what modules you need to load.
+3) load them and run "sensors" command, you should see some results.
+4) fix sensors.conf, labels, limits, fan divisors
+5) if any more problems consult FAQ, or documentation
+Other utilites
+--------------
+If you want some graphical indicators of system health look for applications
+like: gkrellm, ksensors, xsensors, wmtemp, wmsensors, wmgtemp, ksysguardd,
+hardware-monitor
+If you are server administrator you can try snmpd or mrtgutils.

+Documentation for kdump - the kexec-based crash dumping solution
+================================================================
+DESIGN
+======
+Kdump uses kexec to reboot to a second kernel whenever a dump needs to be taken.
+This second kernel is booted with very little memory. The first kernel reserves
+the section of memory that the second kernel uses. This ensures that on-going
+DMA from the first kernel does not corrupt the second kernel.
+All the necessary information about Core image is encoded in ELF format and
+stored in reserved area of memory before crash. Physical address of start of
+ELF header is passed to new kernel through command line parameter elfcorehdr=.
+On i386, the first 640 KB of physical memory is needed to boot, irrespective
+of where the kernel loads. Hence, this region is backed up by kexec just before
+rebooting into the new kernel.
+In the second kernel, "old memory" can be accessed in two ways.
+- The first one is through a /dev/oldmem device interface. A capture utility
+  can read the device file and write out the memory in raw format. This is raw
+  dump of memory and analysis/capture tool should be intelligent enough to
+  determine where to look for the right information. ELF headers (elfcorehdr=)
+  can become handy here.
+- The second interface is through /proc/vmcore. This exports the dump as an ELF
+  format file which can be written out using any file copy command
+  (cp, scp, etc). Further, gdb can be used to perform limited debugging on
+  the dump file. This method ensures methods ensure that there is correct
+  ordering of the dump pages (corresponding to the first 640 KB that has been
+  relocated).
+SETUP
+=====
+1) Download http://www.xmission.com/~ebiederm/files/kexec/kexec-tools-1.101.tar.gz
+   and apply http://lse.sourceforge.net/kdump/patches/kexec-tools-1.101-kdump.patch
+   and after that build the source.
+2) Download and build the appropriate (latest) kexec/kdump (-mm) kernel
+   patchset and apply it to the vanilla kernel tree.
+   Two kernels need to be built in order to get this feature working.
+  A) First kernel:
+   a) Enable "kexec system call" feature (in Processor type and features).
+        CONFIG_KEXEC=y
+   b) This kernel's physical load address should be the default value of
+      0x100000 (0x100000, 1 MB) (in Processor type and features).
+        CONFIG_PHYSICAL_START=0x100000
+   c) Enable "sysfs file system support" (in Pseudo filesystems).
+        CONFIG_SYSFS=y
+   d) Boot into first kernel with the command line parameter "crashkernel=Y@X".
+      Use appropriate values for X and Y. Y denotes how much memory to reserve
+      for the second kernel, and X denotes at what physical address the reserved
+      memory section starts. For example: "crashkernel=64M@16M".
+  B) Second kernel:
+   a) Enable "kernel crash dumps" feature (in Processor type and features).
+        CONFIG_CRASH_DUMP=y
+   b) Specify a suitable value for "Physical address where the kernel is
+      loaded" (in Processor type and features). Typically this value
+      should be same as X (See option d) above, e.g., 16 MB or 0x1000000.
+        CONFIG_PHYSICAL_START=0x1000000
+   c) Enable "/proc/vmcore support" (Optional, in Pseudo filesystems).
+        CONFIG_PROC_VMCORE=y
+   d) Disable SMP support and build a UP kernel (Until it is fixed).
+        CONFIG_SMP=n
+   e) Enable "Local APIC support on uniprocessors".
+        CONFIG_X86_UP_APIC=y
+   f) Enable "IO-APIC support on uniprocessors"
+        CONFIG_X86_UP_IOAPIC=y
+  Note:   i) Options a) and b) depend upon "Configure standard kernel features
+             (for small systems)" (under General setup).
+         ii) Option a) also depends on CONFIG_HIGHMEM (under Processor
+                type and features).
+        iii) Both option a) and b) are under "Processor type and features".
+3) Boot into the first kernel. You are now ready to try out kexec-based crash
+   dumps.
+4) Load the second kernel to be booted using:
+   kexec -p <second-kernel> --crash-dump --args-linux --append="root=<root-dev>
+   init 1 irqpoll"
+   Note: i) <second-kernel> has to be a vmlinux image. bzImage will not work,
+            as of now.
+        ii) By default ELF headers are stored in ELF32 format (for i386). This
+            is sufficient to represent the physical memory up to 4GB. To store
+            headers in ELF64 format, specifiy "--elf64-core-headers" on the
+            kexec command line additionally.
+       iii) Specify "irqpoll" as command line parameter. This reduces driver
+            initialization failures in second kernel due to shared interrupts.
+5) System reboots into the second kernel when a panic occurs. A module can be
+   written to force the panic or "ALT-SysRq-c" can be used initiate a crash
+   dump for testing purposes.
+6) Write out the dump file using
+   cp /proc/vmcore <dump-file>
+   Dump memory can also be accessed as a /dev/oldmem device for a linear/raw
+   view.  To create the device, type:
+   mknod /dev/oldmem c 1 12
+   Use "dd" with suitable options for count, bs and skip to access specific
+   portions of the dump.
+   Entire memory:  dd if=/dev/oldmem of=oldmem.001
+ANALYSIS
+========
+Limited analysis can be done using gdb on the dump file copied out of
+/proc/vmcore. Use vmlinux built with -g and run
+  gdb vmlinux <dump-file>
+Stack trace for the task on processor 0, register display, memory display
+work fine.
+Note: gdb cannot analyse core files generated in ELF64 format for i386.
+TODO
+====
+1) Provide a kernel pages filtering mechanism so that core file size is not
+   insane on systems having huge memory banks.
+2) Modify "crash" tool to make it recognize this dump.

+===================================
+NOTES ON ACCESSING PAYLOAD CONTENTS
+===================================
+The simplest payload is just a number in key->payload.value. In this case,
+there's no need to indulge in RCU or locking when accessing the payload.
+More complex payload contents must be allocated and a pointer to them set in
+key->payload.data. One of the following ways must be selected to access the
+data:
+ (1) Unmodifyable key type.
+     If the key type does not have a modify method, then the key's payload can
+     be accessed without any form of locking, provided that it's known to be
+     instantiated (uninstantiated keys cannot be "found").
+ (2) The key's semaphore.
+     The semaphore could be used to govern access to the payload and to control
+     the payload pointer. It must be write-locked for modifications and would
+     have to be read-locked for general access. The disadvantage of doing this
+     is that the accessor may be required to sleep.
+ (3) RCU.
+     RCU must be used when the semaphore isn't already held; if the semaphore
+     is held then the contents can't change under you unexpectedly as the
+     semaphore must still be used to serialise modifications to the key. The
+     key management code takes care of this for the key type.
+     However, this means using:
+        rcu_read_lock() ... rcu_dereference() ... rcu_read_unlock()
+     to read the pointer, and:
+        rcu_dereference() ... rcu_assign_pointer() ... call_rcu()
+     to set the pointer and dispose of the old contents after a grace period.
+     Note that only the key type should ever modify a key's payload.
+     Furthermore, an RCU controlled payload must hold a struct rcu_head for the
+     use of call_rcu() and, if the payload is of variable size, the length of
+     the payload. key->datalen cannot be relied upon to be consistent with the
+     payload just dereferenced if the key's semaphore is not held.

+- Congestion control
+- How the new TCP output machine [nyi] works
+Congestion control
+==================
+The following variables are used in the tcp_sock for congestion control:
+snd_cwnd                The size of the congestion window
+snd_ssthresh            Slow start threshold. We are in slow start if
+                        snd_cwnd is less than this.
+snd_cwnd_cnt            A counter used to slow down the rate of increase
+                        once we exceed slow start threshold.
+snd_cwnd_clamp          This is the maximum size that snd_cwnd can grow to.
+snd_cwnd_stamp          Timestamp for when congestion window last validated.
+snd_cwnd_used           Used as a highwater mark for how much of the
+                        congestion window is in use. It is used to adjust
+                        snd_cwnd down when the link is limited by the
+                        application rather than the network.
+As of 2.6.13, Linux supports pluggable congestion control algorithms.
+A congestion control mechanism can be registered through functions in
+tcp_cong.c. The functions used by the congestion control mechanism are
+registered via passing a tcp_congestion_ops struct to
+tcp_register_congestion_control. As a minimum name, ssthresh,
+cong_avoid, min_cwnd must be valid.
+Private data for a congestion control mechanism is stored in tp->ca_priv.
+tcp_ca(tp) returns a pointer to this space.  This is preallocated space - it
+is important to check the size of your private data will fit this space, or
+alternatively space could be allocated elsewhere and a pointer to it could
+be stored here.
+There are three kinds of congestion control algorithms currently: The
+simplest ones are derived from TCP reno (highspeed, scalable) and just
+provide an alternative the congestion window calculation. More complex
+ones like BIC try to look at other events to provide better
+heuristics.  There are also round trip time based algorithms like
+Vegas and Westwood+.
+Good TCP congestion control is a complex problem because the algorithm
+needs to maintain fairness and performance. Please review current
+research and RFC's before developing new modules.
+The method that is used to determine which congestion control mechanism is
+determined by the setting of the sysctl net.ipv4.tcp_congestion_control.
+The default congestion control will be the last one registered (LIFO);
+so if you built everything as modules. the default will be reno. If you
+build with the default's from Kconfig, then BIC will be builtin (not a module)
+and it will end up the default.
+If you really want a particular default value then you will need
+to set it with the sysctl.  If you use a sysctl, the module will be autoloaded
+if needed and you will get the expected protocol. If you ask for an
+unknown congestion method, then the sysctl attempt will fail.
+If you remove a tcp congestion control module, then you will get the next
+available one. Since reno can not be built as a module, and can not be
+deleted, it will always be available.
+How the new TCP output machine [nyi] works.

-Linux WAN Router Utilities Package
------------------------------------------------------------------------------
-Version 2.2.1 
-Mar 28, 2001
-Author: Nenad Corbic <ncorbic@sangoma.com>
-Copyright (c) 1995-2001 Sangoma Technologies Inc.
------------------------------------------------------------------------------
-INTRODUCTION
-Wide Area Networks (WANs) are used to interconnect Local Area Networks (LANs)
-and/or stand-alone hosts over vast distances with data transfer rates
-significantly higher than those achievable with commonly used dial-up
-connections.
-Usually an external device called `WAN router' sitting on your local network
-or connected to your machine's serial port provides physical connection to
-WAN.  Although router's job may be as simple as taking your local network
-traffic, converting it to WAN format and piping it through the WAN link, these
-devices are notoriously expensive, with prices as much as 2 - 5 times higher
-then the price of a typical PC box.
-Alternatively, considering robustness and multitasking capabilities of Linux,
-an internal router can be built (most routers use some sort of stripped down
-Unix-like operating system anyway). With a number of relatively inexpensive WAN
-interface cards available on the market, a perfectly usable router can be
-built for less than half a price of an external router.  Yet a Linux box
-acting as a router can still be used for other purposes, such as fire-walling,
-running FTP, WWW or DNS server, etc.
-This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux
-operating system and provides generic hardware-independent services for such
-drivers.  Why can existing Linux network device interface not be used for
-this purpose?  Well, it can.  However, there are a few key differences between
-a typical network interface (e.g. Ethernet) and a WAN link.
-Many WAN protocols, such as X.25 and frame relay, allow for multiple logical
-connections (known as `virtual circuits' in X.25 terminology) over a single
-physical link.  Each such virtual circuit may (and almost always does) lead
-to a different geographical location and, therefore, different network.  As a
-result, it is the virtual circuit, not the physical link, that represents a
-route and, therefore, a network interface in Linux terms.
-To further complicate things, virtual circuits are usually volatile in nature
-(excluding so called `permanent' virtual circuits or PVCs).  With almost no
-time required to set up and tear down a virtual circuit, it is highly desirable
-to implement on-demand connections in order to minimize network charges.  So
-unlike a typical network driver, the WAN driver must be able to handle multiple
-network interfaces and cope as multiple virtual circuits come into existence
-and go away dynamically.
- 
-Last, but not least, WAN configuration is much more complex than that of say
-Ethernet and may well amount to several dozens of parameters.  Some of them
-are "link-wide"  while others are virtual circuit-specific.  The same holds
-true for WAN statistics which is by far more extensive and extremely useful
-when troubleshooting WAN connections.  Extending the ifconfig utility to suit
-these needs may be possible, but does not seem quite reasonable.  Therefore, a
-WAN configuration utility and corresponding application programmer's interface
-is needed for this purpose.
-Most of these problems are taken care of by this module.  Its goal is to
-provide a user with more-or-less standard look and feel for all WAN devices and
-assist a WAN device driver writer by providing common services, such as:
- o User-level interface via /proc file system
- o Centralized configuration
- o Device management (setup, shutdown, etc.)
- o Network interface management (dynamic creation/destruction)
- o Protocol encapsulation/decapsulation
-To ba able to use the Linux WAN Router you will also need a WAN Tools package
-available from
-        ftp.sangoma.com/pub/linux/current_wanpipe/wanpipe-X.Y.Z.tgz
-where vX.Y.Z represent the wanpipe version number.

-ACKNOWLEDGEMENTS
-This product is based on the WANPIPE(tm) Multiprotocol WAN Router developed
-by Sangoma Technologies Inc. for Linux 2.0.x and 2.2.x.  Success of the WANPIPE
-together with the next major release of Linux kernel in summer 1996 commanded
-adequate changes to the WANPIPE code to take full advantage of new Linux
-features.
-Instead of continuing developing proprietary interface tied to Sangoma WAN
-cards, we decided to separate all hardware-independent code into a separate
-module and defined two levels of interfaces - one for user-level applications
-and another for kernel-level WAN drivers.  WANPIPE is now implemented as a
-WAN driver compliant with the WAN Link Driver interface.  Also a general
-purpose WAN configuration utility and a set of shell scripts was developed to 
-support WAN router at the user level.
-Many useful ideas concerning hardware-independent interface implementation
-were given by Mike McLagan <mike.mclagan@linux.org> and his implementation
-of the Frame Relay router and drivers for Sangoma cards (dlci/sdla).
-With the new implementation of the APIs being incorporated into the WANPIPE,
-a special thank goes to Alan Cox in providing insight into BSD sockets.
-Special thanks to all the WANPIPE users who performed field-testing, reported
-bugs and made valuable comments and suggestions that help us to improve this
-product.
-NEW IN THIS RELEASE
-        o Updated the WANCFG utility
-                Calls the pppconfig to configure the PPPD
-                for async connections.
-        o Added the PPPCONFIG utility
-                Used to configure the PPPD dameon for the
-                WANPIPE Async PPP and standard serial port.
-                The wancfg calls the pppconfig to configure
-                the pppd.
-        o Fixed the PCI autodetect feature.  
-                The SLOT 0 was used as an autodetect option
-                however, some high end PC's slot numbers start
-                from 0. 
-        o This release has been tested with the new backupd
-          daemon release.

-beta-2.1.4 Jul 2000             o Dynamic interface configuration:
-                                        Network interfaces reflect the state
-                                        of protocol layer.  If the protocol becomes
-                                        disconnected, driver will bring down
-                                        the interface.  Once the protocol reconnects
-                                        the interface will be brought up. 
-                                        
-                                        Note: This option is turned off by default.
-                                o Dynamic wanrouter setup using 'wanconfig':
-                                        wanconfig utility can be used to
-                                        shutdown,restart,start or reconfigure 
-                                        a virtual circuit dynamically.
-                                     
-                                        Frame Relay:  Each DLCI can be: 
-                                                      created,stopped,restarted and reconfigured
-                                                      dynamically using wanconfig.
-                                        
-                                                      ex: wanconfig card wanpipe1 dev wp1_fr16 up
-                                  
-                                o Wanrouter startup via command line arguments:
-                                        wanconfig also supports wanrouter startup via command line
-                                        arguments.  Thus, there is no need to create a wanpipe#.conf
-                                        configuration file.  
-                                o Socket based x25api update/bug fixes.
-                                        Added support for LCN numbers greater than 255.
-                                        Option to pass up modem messages.
-                                        Provided a PCI IRQ check, so a single S514
-                                        card is guaranteed to have a non-sharing interrupt.
-                                o Fixes to the wancfg utility.
-                                o New FT1 debugging support via *pipemon utilities.
-                                o Frame Relay ARP support Enabled.
-beta3-2.1.4 Jul 2000            o X25 M_BIT Problem fix.
-                                o Added the Multi-Port PPP
-                                  Updated utilites for the Multi-Port PPP.
-2.1.4   Aut 2000
-                                o In X25API:
-                                        Maximum packet an application can send
-                                        to the driver has been extended to 4096 bytes.
-                                        Fixed the x25 startup bug. Enable 
-                                        communications only after all interfaces
-                                        come up.  HIGH SVC/PVC is used to calculate
-                                        the number of channels.
-                                        Enable protocol only after all interfaces
-                                        are enabled.
-                                o Added an extra state to the FT1 config, kernel module.
-                                o Updated the pipemon debuggers.
-                                o Blocked the Multi-Port PPP from running on kernels
-                                  2.2.16 or greater, due to syncppp kernel module
-                                  change. 
-          
-beta1-2.1.5     Nov 15 2000
-                                o Fixed the MulitPort PPP Support for kernels 2.2.16 and above.
-                                  2.2.X kernels only
-                                o Secured the driver UDP debugging calls
-                                        - All illegal netowrk debugging calls are reported to
-                                          the log.
-                                        - Defined a set of allowed commands, all other denied.
-                                        
-                                o Cpipemon
-                                        - Added set FT1 commands to the cpipemon. Thus CSU/DSU
-                                          configuraiton can be performed using cpipemon.
-                                          All systems that cannot run cfgft1 GUI utility should
-                                          use cpipemon to configure the on board CSU/DSU.
-                                o Keyboard Led Monitor/Debugger
-                                        - A new utilty /usr/sbin/wpkbdmon uses keyboard leds
-                                          to convey operatinal statistic information of the 
-                                          Sangoma WANPIPE cards.
-                                        NUM_LOCK    = Line State  (On=connected,    Off=disconnected)
-                                        CAPS_LOCK   = Tx data     (On=transmitting, Off=no tx data)
-                                        SCROLL_LOCK = Rx data     (On=receiving,    Off=no rx data
-                                        
-                                o Hardware probe on module load and dynamic device allocation
-                                        - During WANPIPE module load, all Sangoma cards are probed
-                                          and found information is printed in the /var/log/messages.
-                                        - If no cards are found, the module load fails.
-                                        - Appropriate number of devices are dynamically loaded 
-                                          based on the number of Sangoma cards found.
-                                          Note: The kernel configuraiton option 
-                                                CONFIG_WANPIPE_CARDS has been taken out.
-                                        
-                                o Fixed the Frame Relay and Chdlc network interfaces so they are
-                                  compatible with libpcap libraries.  Meaning, tcpdump, snort,
-                                  ethereal, and all other packet sniffers and debuggers work on
-                                  all WANPIPE netowrk interfaces.
-                                        - Set the network interface encoding type to ARPHRD_PPP.
-                                          This tell the sniffers that data obtained from the
-                                          network interface is in pure IP format.
-                                  Fix for 2.2.X kernels only.
-                                
-                                o True interface encoding option for Frame Relay and CHDLC
-                                        - The above fix sets the network interface encoding
-                                          type to ARPHRD_PPP, however some customers use
-                                          the encoding interface type to determine the
-                                          protocol running.  Therefore, the TURE ENCODING
-                                          option will set the interface type back to the
-                                          original value.  
-                                          NOTE: If this option is used with Frame Relay and CHDLC
-                                                libpcap library support will be broken.  
-                                                i.e. tcpdump will not work.
-                                        Fix for 2.2.x Kernels only.
-                                                
-                                o Ethernet Bridgind over Frame Relay
-                                        - The Frame Relay bridging has been developed by 
-                                          Kristian Hoffmann and Mark Wells.  
-                                        - The Linux kernel bridge is used to send ethernet 
-                                          data over the frame relay links.
-                                        For 2.2.X Kernels only.
-                                o Added extensive 2.0.X support. Most new features of
-                                  2.1.5 for protocols Frame Relay, PPP and CHDLC are
-                                  supported under 2.0.X kernels. 
-beta1-2.2.0     Dec 30 2000
-                                o Updated drivers for 2.4.X kernels.
-                                o Updated drivers for SMP support.
-                                o X25API is now able to share PCI interrupts.
-                                o Took out a general polling routine that was used
-                                  only by X25API. 
-                                o Added appropriate locks to the dynamic reconfiguration
-                                  code.
-                                o Fixed a bug in the keyboard debug monitor.
-beta2-2.2.0     Jan 8 2001
-                                o Patches for 2.4.0 kernel
-                                o Patches for 2.2.18 kernel
-                                o Minor updates to PPP and CHLDC drivers.
-                                  Note: No functinal difference. 
-beta3-2.2.9     Jan 10 2001
-                                o I missed the 2.2.18 kernel patches in beta2-2.2.0
-                                  release.  They are included in this release.
-Stable Release
-2.2.0           Feb 01 2001
-                                o Bug fix in wancfg GUI configurator.
-                                        The edit function didn't work properly.
-bata1-2.2.1     Feb 09 2001
-                        o WANPIPE TTY Driver emulation. 
-                          Two modes of operation Sync and Async.
-                                Sync: Using the PPPD daemon, kernel SyncPPP layer
-                                      and the Wanpipe sync TTY driver: a PPP protocol 
-                                      connection can be established via Sangoma adapter, over
-                                      a T1 leased line.
-                        
-                                      The 2.4.0 kernel PPP layer supports MULTILINK
-                                      protocol, that can be used to bundle any number of Sangoma
-                                      adapters (T1 lines) into one, under a single IP address.
-                                      Thus, efficiently obtaining multiple T1 throughput. 
-                                      NOTE: The remote side must also implement MULTILINK PPP
-                                            protocol.
-                                Async:Using the PPPD daemon, kernel AsyncPPP layer
-                                      and the WANPIPE async TTY driver: a PPP protocol
-                                      connection can be established via Sangoma adapter and
-                                      a modem, over a telephone line.
-                                      Thus, the WANPIPE async TTY driver simulates a serial
-                                      TTY driver that would normally be used to interface the 
-                                      MODEM to the linux kernel.
-

+      resume(): devices are woken up so that system can continue
+      thaw all user processes
+Q: What is this 'Encrypt suspend image' for?
+A: First of all: it is not a replacement for dm-crypt encrypted swap.
+It cannot protect your computer while it is suspended. Instead it does
+protect from leaking sensitive data after resume from suspend.
+Think of the following: you suspend while an application is running
+that keeps sensitive data in memory. The application itself prevents
+the data from being swapped out. Suspend, however, must write these
+data to swap to be able to resume later on. Without suspend encryption
+your sensitive data are then stored in plaintext on disk.  This means
+that after resume your sensitive data are accessible to all
+applications having direct access to the swap device which was used
+for suspend. If you don't need swap after resume these data can remain
+on disk virtually forever. Thus it can happen that your system gets
+broken in weeks later and sensitive data which you thought were
+encrypted and protected are retrieved and stolen from the swap device.
+To prevent this situation you should use 'Encrypt suspend image'.
+During suspend a temporary key is created and this key is used to
+encrypt the data written to disk. When, during resume, the data was
+read back into memory the temporary key is destroyed which simply
+means that all data written to disk during suspend are then
+inaccessible so they can't be stolen later on.  The only thing that
+you must then take care of is that you call 'mkswap' for the swap
+partition used for suspend as early as possible during regular
+boot. This asserts that any temporary key from an oopsed suspend or
+from a failed or aborted resume is erased from the swap device.
+As a rule of thumb use encrypted swap to protect your data while your
+system is shut down or suspended. Additionally use the encrypted
+suspend image to prevent sensitive data from being stolen after
+resume.

+README for the SCSI media changer driver
+========================================
+This is a driver for SCSI Medium Changer devices, which are listed
+with "Type: Medium Changer" in /proc/scsi/scsi.
+This is for *real* Jukeboxes.  It is *not* supported to work with
+common small CD-ROM changers, neither one-lun-per-slot SCSI changers
+nor IDE drives.
+Userland tools available from here:
+        http://linux.bytesex.org/misc/changer.html
+General Information
+-------------------
+First some words about how changers work: A changer has 2 (possibly
+more) SCSI ID's. One for the changer device which controls the robot,
+and one for the device which actually reads and writes the data. The
+later may be anything, a MOD, a CD-ROM, a tape or whatever. For the
+changer device this is a "don't care", he *only* shuffles around the
+media, nothing else.
+The SCSI changer model is complex, compared to - for example - IDE-CD
+changers. But it allows to handle nearly all possible cases. It knows
+4 different types of changer elements:
+  media transport - this one shuffles around the media, i.e. the
+                    transport arm.  Also known as "picker".
+  storage         - a slot which can hold a media.
+  import/export   - the same as above, but is accessable from outside,
+                    i.e. there the operator (you !) can use this to
+                    fill in and remove media from the changer.
+                    Sometimes named "mailslot".
+  data transfer   - this is the device which reads/writes, i.e. the
+                    CD-ROM / Tape / whatever drive.
+None of these is limited to one: A huge Jukebox could have slots for
+123 CD-ROM's, 5 CD-ROM readers (and therefore 6 SCSI ID's: the changer
+and each CD-ROM) and 2 transport arms. No problem to handle.
+How it is implemented
+---------------------
+I implemented the driver as character device driver with a NetBSD-like
+ioctl interface. Just grabbed NetBSD's header file and one of the
+other linux SCSI device drivers as starting point. The interface
+should be source code compatible with NetBSD. So if there is any
+software (anybody knows ???) which supports a BSDish changer driver,
+it should work with this driver too.
+Over time a few more ioctls where added, volume tag support for example
+wasn't covered by the NetBSD ioctl API.
+Current State
+-------------
+Support for more than one transport arm is not implemented yet (and
+nobody asked for it so far...).
+I test and use the driver myself with a 35 slot cdrom jukebox from
+Grundig.  I got some reports telling it works ok with tape autoloaders
+(Exabyte, HP and DEC).  Some People use this driver with amanda.  It
+works fine with small (11 slots) and a huge (4 MOs, 88 slots)
+magneto-optical Jukebox.  Probably with lots of other changers too, most
+(but not all :-) people mail me only if it does *not* work...
+I don't have any device lists, neither black-list nor white-list.  Thus
+it is quite useless to ask me whenever a specific device is supported or
+not.  In theory every changer device which supports the SCSI-2 media
+changer command set should work out-of-the-box with this driver.  If it
+doesn't, it is a bug.  Either within the driver or within the firmware
+of the changer device.
+Using it
+--------
+This is a character device with major number is 86, so use
+"mknod /dev/sch0 c 86 0" to create the special file for the driver.
+If the module finds the changer, it prints some messages about the
+device [ try "dmesg" if you don't see anything ] and should show up in
+/proc/devices. If not....  some changers use ID ? / LUN 0 for the
+device and ID ? / LUN 1 for the robot mechanism. But Linux does *not*
+look for LUN's other than 0 as default, becauce there are to many
+broken devices. So you can try:
+  1) echo "scsi add-single-device 0 0 ID 1" > /proc/scsi/scsi
+     (replace ID with the SCSI-ID of the device)
+  2) boot the kernel with "max_scsi_luns=1" on the command line
+     (append="max_scsi_luns=1" in lilo.conf should do the trick)
+Trouble?
+--------
+If you insmod the driver with "insmod debug=1", it will be verbose and
+prints a lot of stuff to the syslog.  Compiling the kernel with
+CONFIG_SCSI_CONSTANTS=y improves the quality of the error messages alot
+because the kernel will translate the error codes into human-readable
+strings then.
+You can display these messages with the dmesg command (or check the
+logfiles).  If you email me some question becauce of a problem with the
+driver, please include these messages.
+Insmod options
+--------------
+debug=0/1
+        Enable debug messages (see above, default: 0).
+verbose=0/1
+        Be verbose (default: 1).
+init=0/1
+        Send INITIALIZE ELEMENT STATUS command to the changer
+        at insmod time (default: 1).
+timeout_init=<seconds>
+        timeout for the INITIALIZE ELEMENT STATUS command
+        (default: 3600).
+timeout_move=<seconds>
+        timeout for all other commands (default: 120).
+dt_id=<id1>,<id2>,...
+dt_lun=<lun1>,<lun2>,...
+        These two allow to specify the SCSI ID and LUN for the data
+        transfer elements.  You likely don't need this as the jukebox
+        should provide this information.  But some devices don't ...
+vendor_firsts=
+vendor_counts=
+vendor_labels=
+        These insmod options can be used to tell the driver that there
+        are some vendor-specific element types.  Grundig for example
+        does this.  Some jukeboxes have a printer to label fresh burned
+        CDs, which is addressed as element 0xc000 (type 5).  To tell the
+        driver about this vendor-specific element, use this:
+                $ insmod ch                     \
+                        vendor_firsts=0xc000    \
+                        vendor_counts=1         \
+                        vendor_labels=printer
+        All three insmod options accept up to four comma-separated
+        values, this way you can configure the element types 5-8.
+        You likely need the SCSI specs for the device in question to
+        find the correct values as they are not covered by the SCSI-2
+        standard.

+The SGI IOC4 PCI device is a bit of a strange beast, so some notes on
+it are in order.
+First, even though the IOC4 performs multiple functions, such as an
+IDE controller, a serial controller, a PS/2 keyboard/mouse controller,
+and an external interrupt mechanism, it's not implemented as a
+multifunction device.  The consequence of this from a software
+standpoint is that all these functions share a single IRQ, and
+they can't all register to own the same PCI device ID.  To make
+matters a bit worse, some of the register blocks (and even registers
+themselves) present in IOC4 are mixed-purpose between these several
+functions, meaning that there's no clear "owning" device driver.
+The solution is to organize the IOC4 driver into several independent
+drivers, "ioc4", "sgiioc4", and "ioc4_serial".  Note that there is no
+PS/2 controller driver as this functionality has never been wired up
+on a shipping IO card.
+ioc4
+====
+This is the core (or shim) driver for IOC4.  It is responsible for
+initializing the basic functionality of the chip, and allocating
+the PCI resources that are shared between the IOC4 functions.
+This driver also provides registration functions that the other
+IOC4 drivers can call to make their presence known.  Each driver
+needs to provide a probe and remove function, which are invoked
+by the core driver at appropriate times.  The interface of these
+IOC4 function probe and remove operations isn't precisely the same
+as PCI device probe and remove operations, but is logically the
+same operation.
+sgiioc4
+=======
+This is the IDE driver for IOC4.  Its name isn't very descriptive
+simply for historical reasons (it used to be the only IOC4 driver
+component).  There's not much to say about it other than it hooks
+up to the ioc4 driver via the appropriate registration, probe, and
+remove functions.
+ioc4_serial
+===========
+This is the serial driver for IOC4.  There's not much to say about it
+other than it hooks up to the ioc4 driver via the appropriate registration,
+probe, and remove functions.

+=======================
+Some drivers (e.g. hdsp) require the large contiguous buffers, and
+sometimes it's too late to find such spaces when the driver module is
+actually loaded due to memory fragmentation.  You can pre-allocate the
+PCM buffers by loading snd-page-alloc module and write commands to its
+proc file in prior, for example, in the early boot stage like
+/etc/init.d/*.local scripts.
+Reading the proc file /proc/drivers/snd-page-alloc shows the current
+usage of page allocation.  In writing, you can send the following
+commands to the snd-page-alloc driver:
+  - add VENDOR DEVICE MASK SIZE BUFFERS
+    VENDOR and DEVICE are PCI vendor and device IDs.  They take
+    integer numbers (0x prefix is needed for the hex).
+    MASK is the PCI DMA mask.  Pass 0 if not restricted.
+    SIZE is the size of each buffer to allocate.  You can pass
+    k and m suffix for KB and MB.  The max number is 16MB.
+    BUFFERS is the number of buffers to allocate.  It must be greater

+This document is a guide to using the emu10k1 based devices with JACK for low

+Linux users to use the full capabilities of their hardware has been inspired 
+by the kX Project.  Without their work I never would have discovered the true
+power of this hardware.

+                                                - Lee Revell, 2005.03.30
+Low latency, multichannel audio with JACK and the emu10k1/emu10k2
+-----------------------------------------------------------------
+Until recently, emu10k1 users on Linux did not have access to the same low
+latency, multichannel features offered by the "kX ASIO" feature of their
+Windows driver.  As of ALSA 1.0.9 this is no more!
+For those unfamiliar with kX ASIO, this consists of 16 capture and 16 playback
+channels.  With a post 2.6.9 Linux kernel, latencies down to 64 (1.33 ms) or
+even 32 (0.66ms) frames should work well.
+The configuration is slightly more involved than on Windows, as you have to
+select the correct device for JACK to use.  Actually, for qjackctl users it's
+fairly self explanatory - select Duplex, then for capture and playback select
+the multichannel devices, set the in and out channels to 16, and the sample
+rate to 48000Hz.  The command line looks like this:
+/usr/local/bin/jackd -R -dalsa -r48000 -p64 -n2 -D -Chw:0,2 -Phw:0,3 -S
+This will give you 16 input ports and 16 output ports.
+The 16 output ports map onto the 16 FX buses (or the first 16 of 64, for the
+Audigy).  The mapping from FX bus to physical output is described in
+SB-Live-mixer.txt (or Audigy-mixer.txt).
+The 16 input ports are connected to the 16 physical inputs.  Contrary to
+popular belief, all emu10k1 cards are multichannel cards.  Which of these
+input channels have physical inputs connected to them depends on the card
+model.  Trial and error is highly recommended; the pinout diagrams
+for the card have been reverse engineered by some enterprising kX users and are 
+available on the internet.  Meterbridge is helpful here, and the kX forums are
+packed with useful information.
+Each input port will either correspond to a digital (SPDIF) input, an analog
+input, or nothing.  The one exception is the SBLive! 5.1.  On these devices,
+the second and third input ports are wired to the center/LFE output.  You will
+still see 16 capture channels, but only 14 are available for recording inputs.
+This chart, borrowed from kxfxlib/da_asio51.cpp, describes the mapping of JACK
+ports to FXBUS2 (multitrack recording input) and EXTOUT (physical output)
+channels.

+                 ALSA. In theory now you can get now a latency as low as 16
+                 Samples, which is a quarter of the interrupt possibilities.)

+   Controller:
+          Since DSP-MADI-Mixer has 8152 Fader, it does not make sense to
+          use the standard mixer-controls, since this would break most of
+          (especially graphic) ALSA-Mixer GUIs. So Mixer control has be
+          provided by a 2-dimensional controller using the
+          hwdep-interface. 
+     Also all 128+256 Peak and RMS-Meter can be accessed via the
+     hwdep-interface. Since it could be a performance problem always
+     copying and converting Peak and RMS-Levels even if you just need
+     one, I decided to export the hardware structure, so that of
+     needed some driver-guru can implement a memory-mapping of mixer
+     or peak-meters over ioctl, or also to do only copying and no
+     conversion. A test-application shows the usage of the controller.
+    Latency Controls --- not implemented !!!
+           Note: Within the windows-driver the latency is accessible of a
+           control-panel, but buffer-sizes are controlled with ALSA from
+           hwparams-calls and should not be changed in run-state, I did not
+           implement it here.

+                  makes sense to set the card to a special mode (master at some
+                  frequency or slave), since even not using an Audio-application
+                  a studio should have working synchronisations setup. So use

+                 Note: Since MADI has a much higher bit-rate than word-clock, the

+bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data)  An
+actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
+I'm pretty sure when no IR signal is present the receiver is always in a
+marking state(1); but stray light, etc can cause intermittent noise values
+as well.  Remember, this is a free running sample of the IR receiver state
+over time, so don't assume any sample starts at any particular place.

+What does the w1 subsystem do?
+------------------------------------------------------------------
+When a w1 master driver registers with the w1 subsystem, the following occurs:
+ - sysfs entries for that w1 master are created
+ - the w1 bus is periodically searched for new slave devices
+When a device is found on the bus, w1 core checks if driver for it's family is
+loaded. If so, the family driver is attached to the slave.
+If there is no driver for the family, a simple sysfs entry is created
+for the slave device.
+W1 device families
+------------------------------------------------------------------
+Slave devices are handled by a driver written for a family of w1 devices.
+A family driver populates a struct w1_family_ops (see w1_family.h) and
+registers with the w1 subsystem.
+Current family drivers:
+w1_therm - (ds18?20 thermal sensor family driver)
+    provides temperature reading function which is bound to ->rbin() method
+    of the above w1_family_ops structure.
+w1_smem - driver for simple 64bit memory cell provides ID reading method.
 You can call above methods by reading appropriate sysfs files.
+What does a w1 master driver need to implement?
+------------------------------------------------------------------
+The driver for w1 bus master must provide at minimum two functions.
+Emulated devices must provide the ability to set the output signal level
+(write_bit) and sample the signal level (read_bit).
+Devices that support the 1-wire natively must provide the ability to write and
+sample a bit (touch_bit) and reset the bus (reset_bus).
+Most hardware provides higher-level functions that offload w1 handling.
+See struct w1_bus_master definition in w1.h for details.

+w1_master_max_slave_count
+                   - the maximum slaves that may be attached to a master
