+
+Panic Timeouts
+--------------
+
+The OpenIPMI driver supports the ability to put semi-custom and custom
+events in the system event log if a panic occurs.  if you enable the
+'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.
+
+
+Poweroff
+--------
+
+If the poweroff capability is selected, the IPMI driver will install
+a shutdown function into the standard poweroff function pointer.  This
+is in the ipmi_poweroff module.  When the system requests a powerdown,
+it will send the proper IPMI commands to do this.  This is supported on

+Block io priorities
+===================
+
+
+Intro
+-----
+
+With the introduction of cfq v3 (aka cfq-ts or time sliced cfq), basic io
+priorities is supported for reads on files. This enables users to io nice
+processes or process groups, similar to what has been possible to cpu
+scheduling for ages. This document mainly details the current possibilites
+with cfq, other io schedulers do not support io priorities so far.
+
+Scheduling classes
+------------------
+
+CFQ implements three generic scheduling classes that determine how io is
+served for a process.
+
+IOPRIO_CLASS_RT: This is the realtime io class. This scheduling class is given
+higher priority than any other in the system, processes from this class are
+given first access to the disk every time. Thus it needs to be used with some
+care, one io RT process can starve the entire system. Within the RT class,
+there are 8 levels of class data that determine exactly how much time this
+process needs the disk for on each service. In the future this might change
+to be more directly mappable to performance, by passing in a wanted data
+rate instead.
+
+IOPRIO_CLASS_BE: This is the best-effort scheduling class, which is the default
+for any process that hasn't set a specific io priority. The class data
+determines how much io bandwidth the process will get, it's directly mappable
+to the cpu nice levels just more coarsely implemented. 0 is the highest
+BE prio level, 7 is the lowest. The mapping between cpu nice level and io
+nice level is determined as: io_nice = (cpu_nice + 20) / 5.
+
+IOPRIO_CLASS_IDLE: This is the idle scheduling class, processes running at this
+level only get io time when no one else needs the disk. The idle class has no
+class data, since it doesn't really apply here.
+
+Tools
+-----
+
+See below for a sample ionice tool. Usage:
+
+# ionice -c<class> -n<level> -p<pid>
+
+If pid isn't given, the current process is assumed. IO priority settings
+are inherited on fork, so you can use ionice to start the process at a given
+level:
+
+# ionice -c2 -n0 /bin/ls
+
+will run ls at the best-effort scheduling class at the highest priority.
+For a running process, you can give the pid instead:
+
+# ionice -c1 -n2 -p100
+
+will change pid 100 to run at the realtime scheduling class, at priority 2.

+Quite keen I wanted to put the driver (with some quirks of course) into dibusb.
+After reading some specs and doing some USB snooping, it realized, that the
+dibusb-driver would be a complete mess afterwards. So I decided to do it in a

-This program is free software; you can redistribute it and/or
-modify it under the terms of the GNU General Public License as
-published by the Free Software Foundation, version 2.
+The framework provides generic functions (mostly kernel API calls), such as:
 
+- Transport Stream URB handling in conjunction with dvb-demux-feed-control
+  (bulk and isoc (TODO) are supported)
+- registering the device for the DVB-API
+- registering an I2C-adapter if applicable
+- remote-control/input-device handling
+- firmware requesting and loading (currently just for the Cypress USB
+  controller)
+- other functions/methods which can be shared by several drivers (such as
+  functions for bulk-control-commands)
+
+The source code of the particular DVB USB devices does just the communication
+with the device via the bus. The connection between the DVB-API-functionality
+is done via callbacks, assigned in a static device-description (struct
+dvb_usb_device) each device-driver has to have.
+
+For an example have a look in drivers/media/dvb/dvb-usb/vp7045*.
+
+Objective is to migrate all the usb-devices (dibusb, cinergyT2, maybe the
+ttusb; flexcop-usb already benefits from the generic flexcop-device) to use
+the dvb-usb-lib.

+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.

+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

+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.

+Description
+-----------
+
+The ADM1030 and ADM1031 are digital temperature sensors and fan controllers.
+They sense their own temperature as well as the temperature of up to one
+(ADM1030) or two (ADM1031) external diodes.
+
+All temperature values are given in degrees Celsius. Resolution is 0.5
+degree for the local temperature, 0.125 degree for the remote temperatures.
+
+Each temperature channel has its own high and low limits, plus a critical
+limit.
+
+The ADM1030 monitors a single fan speed, while the ADM1031 monitors up to
+two. Each fan channel has its own low speed limit.

+
+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

+     3      +5 V_Error          high or 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.

+====================

+
+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.

+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.

+Kernel driver lm63
+==================
+
+Supported chips:

+    Prefix: 'lm63'
+    Addresses scanned: I2C 0x4c
+    Datasheet: Publicly available at the National Semiconductor website

+
+Author: Jean Delvare <khali@linux-fr.org>
+
+Thanks go to Tyan and especially Alex Buckingham for setting up a remote
+access to their S4882 test platform for this driver.
+  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
+-----------
+
+This driver implements support for the National Semiconductor LM80.
+It is described as a 'Serial Interface ACPI-Compatible Microprocessor
+System Hardware Monitor'.
+
+The LM80 implements one temperature sensor, two fan rotation speed sensors,
+seven voltage sensors, alarms, and some miscellaneous stuff.
+
+Temperatures are measured in degrees Celsius. There are two sets of limits
+which operate independently. When the HOT Temperature Limit is crossed,
+this will cause an alarm that will be reasserted until the temperature
+drops below the HOT Hysteresis. The Overtemperature Shutdown (OS) limits
+should work in the same way (but this must be checked; the datasheet
+is unclear about this). Measurements are guaranteed between -55 and
++125 degrees. The current temperature measurement has a resolution of
+0.0625 degrees; the limits have 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 2.55 volts, with a resolution
+of 0.01 volt.
+
+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 LM80 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 Forsström, 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)

+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.

+
+Also note that for the PC87366, initialization levels 2 and 3 don't enable

+
+
+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.

+  PC87366     11      3       3       3-4     0xE9
+
+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.

+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.

+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.

+  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

+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.

+# 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.

+This driver provides kernel support for Davicom DM9102(A)/DM9132/DM9801 ethernet cards ( CNET
+10/100 ethernet cards uses Davicom chipset too, so this driver supports CNET cards too ).If you
+didn't compile this driver as a module, it will automatically load itself on boot and print a
+line similar to :
 
-  A. Compiler command:
+	dmfe: Davicom DM9xxx net driver, version 1.36.4 (2002-01-17)
 
-     A-1: For normal single or multiple processor kernel
-          "gcc -DMODULE -D__KERNEL__ -I/usr/src/linux/net/inet -Wall 
-            -Wstrict-prototypes -O6 -c dmfe.c"
+If you compiled this driver as a module, you have to load it on boot.You can load it with command :
 
-     A-2: For single or multiple processor with kernel module version function
-          "gcc -DMODULE -DMODVERSIONS -D__KERNEL__ -I/usr/src/linux/net/inet 
-            -Wall -Wstrict-prototypes -O6 -c dmfe.c"
+	insmod dmfe
 
+This way it will autodetect the device mode.This is the suggested way to load the module.Or you can pass
+a mode= setting to module while loading, like :
 
-  B. The following steps teach you how to activate a DM9102 board:
+	insmod dmfe mode=0 # Force 10M Half Duplex
+	insmod dmfe mode=1 # Force 100M Half Duplex
+	insmod dmfe mode=4 # Force 10M Full Duplex
+	insmod dmfe mode=5 # Force 100M Full Duplex
 
-        1. Used the upper compiler command to compile dmfe.c
+Next you should configure your network interface with a command similar to :
 
-        2. Insert dmfe module into kernel
-           "insmod dmfe"        ;;Auto Detection Mode (Suggest)
-           "insmod dmfe mode=0" ;;Force 10M Half Duplex
-           "insmod dmfe mode=1" ;;Force 100M Half Duplex
-           "insmod dmfe mode=4" ;;Force 10M Full Duplex
-           "insmod dmfe mode=5" ;;Force 100M Full Duplex
+	ifconfig eth0 172.22.3.18
+                      ^^^^^^^^^^^
+		     Your IP Adress
 
-        3. Config a dm9102 network interface
-           "ifconfig eth0 172.22.3.18"
-                          ^^^^^^^^^^^ Your IP address
+Then you may have to modify the default routing table with command :
 
-        4. Activate the IP routing table. For some distributions, it is not
-           necessary. You can type "route" to check.
+	route add default eth0
 
-           "route add default eth0"
 
+Now your ethernet card should be up and running.
 
-        5. Well done. Your DM9102 adapter is now activated.
 
+TODO:
 
-   C. Object files description:
-        1. dmfe_rh61.o:       	For Redhat 6.1
+Implement pci_driver::suspend() and pci_driver::resume() power management methods.
+Check on 64 bit boxes.
+Check and fix on big endian boxes.
+Test and make sure PCI latency is now correct for all cases.
 
-        If you can make sure your kernel version, you can rename
-        to dmfe.o and directly use it without re-compiling.

-How the new TCP output machine [nyi] works.
+TCP protocol
+============
+
+Last updated: 21 June 2005
+
+Contents

+
+- 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>

-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.

-				o wancfg GUI configuration file 
-				  configurator.
-				o Architectual directory changes.
-
-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.
-				
-			o WANPIPE PPP Backup Utility
-				This utility will monitor the state of the PPP T1 line.
-				In case of failure, a dial up connection will be established
-				via pppd daemon, ether via a serial tty driver (serial port), 
-				or a WANPIPE async TTY driver (in case serial port is unavailable).
-				
-				Furthermore, while in dial up mode, the primary PPP T1 link
-				will be monitored for signs of life.  
-
-				If the PPP T1 link comes back to life, the dial up connection
-				will be shutdown and T1 line re-established.
-			
-
-			o New Setup installation script.
-				Option to UPGRADE device drivers if the kernel source has
-				already been patched with WANPIPE.
-
-				Option to COMPILE WANPIPE modules against the currently 
-				running kernel, thus no need for manual kernel and module
-				re-compilatin.
-			
-			o Updates and Bug Fixes to wancfg utility.
-
-bata2-2.2.1	Feb 20 2001
-
-			o Bug fixes to the CHDLC device drivers.
-				The driver had compilation problems under kernels
-				2.2.14 or lower.
-
-			o Bug fixes to the Setup installation script.
-				The device drivers compilation options didn't work
-				properly.
-
-			o Update to the wpbackupd daemon.  
-				Optimized the cross-over times, between the primary
-				link and the backup dialup.
-
-beta3-2.2.1	Mar 02 2001
-			o Patches for 2.4.2 kernel.
-
-			o Bug fixes to util/ make files.
-			o Bug fixes to the Setup installation script.
-
-			o Took out the backupd support and made it into
-			  as separate package.
-			  
-beta4-2.2.1     Mar 12 2001
-
-		o Fix to the Frame Relay Device driver.
-			IPSAC sends a packet of zero length
-			header to the frame relay driver.  The
-			driver tries to push its own 2 byte header
-			into the packet, which causes the driver to
-			crash.
-
-		o Fix the WANPIPE re-configuration code.
-			Bug was found by trying to run  the cfgft1 while the
-			interface was already running.  
-
-		o Updates to cfgft1.
-			Writes a wanpipe#.cfgft1 configuration file
-			once the CSU/DSU is configured. This file can
-			holds the current CSU/DSU configuration.

+Matching of PCMCIA devices to drivers is done using one or more of the
+following criteria:
+
+- manufactor ID
+- card ID
+- product ID strings _and_ hashes of these strings
+- function ID
+- device function (actual and pseudo)
+
+You should use the helpers in include/pcmcia/device_id.h for generating the
+struct pcmcia_device_id[] entries which match devices to drivers.
+
+If you want to match product ID strings, you also need to pass the crc32
+hashes of the string to the macro, e.g. if you want to match the product ID
+string 1, you need to use
+
+PCMCIA_DEVICE_PROD_ID1("some_string", 0x(hash_of_some_string)),
+
+If the hash is incorrect, the kernel will inform you about this in "dmesg"
+upon module initialization, and tell you of the correct hash.
+
+You can determine the hash of the product ID strings by catting the file
+"modalias" in the sysfs directory of the PCMCIA device. It generates a string
+in the following form:
+pcmcia:m0149cC1ABf06pfn00fn00pa725B842DpbF1EFEE84pc0877B627pd00000000
+
+The hex value after "pa" is the hash of product ID string 1, after "pb" for
+string 2 and so on.
+
+Alternatively, you can use this small tool to determine the crc32 hash.
+simply pass the string you want to evaluate as argument to this program,
+e.g.
+$ ./crc32hash "Dual Speed"
+

+This file details changes in 2.6 which affect PCMCIA card driver authors:
+
+* in-kernel device<->driver matching
+   PCMCIA devices and their correct drivers can now be matched in
+   kernelspace. See 'devicetable.txt' for details.
+
+* Device model integration (as of 2.6.11)
+   A struct pcmcia_device is registered with the device model core,
+   and can be used (e.g. for SET_NETDEV_DEV) by using
+   handle_to_dev(client_handle_t * handle).
+
+* Convert internal I/O port addresses to unsigned long (as of 2.6.11)
+   ioaddr_t should be replaced by kio_addr_t in PCMCIA card drivers.
+
+* irq_mask and irq_list parameters (as of 2.6.11)
+   The irq_mask and irq_list parameters should no longer be used in
+   PCMCIA card drivers. Instead, it is the job of the PCMCIA core to
+   determine which IRQ should be used. Therefore, link->irq.IRQInfo2
+   is ignored.
+
+* client->PendingEvents is gone (as of 2.6.11)
+   client->PendingEvents is no longer available.
+
+* client->Attributes are gone (as of 2.6.11)
+   client->Attributes is unused, therefore it is removed from all
+   PCMCIA card drivers
+
+* core functions no longer available (as of 2.6.11)
+   The following functions have been removed from the kernel source
+   because they are unused by all in-kernel drivers, and no external
+   driver was reported to rely on them:
+	pcmcia_get_first_region()
+	pcmcia_get_next_region()
+	pcmcia_modify_window()
+	pcmcia_set_event_mask()
+	pcmcia_get_first_window()
+	pcmcia_get_next_window()
+
+* device list iteration upon module removal (as of 2.6.10)
+   It is no longer necessary to iterate on the driver's internal
+   client list and call the ->detach() function upon module removal.
+
+* Resource management. (as of 2.6.8)
+   Although the PCMCIA subsystem will allocate resources for cards,
+   it no longer marks these resources busy. This means that driver
+   authors are now responsible for claiming your resources as per
+   other drivers in Linux. You should use request_region() to mark
+   your IO regions in-use, and request_mem_region() to mark your
+   memory regions in-use. The name argument should be a pointer to
+   your driver name. Eg, for pcnet_cs, name should point to the
+   string "pcnet_cs".

+
+      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.

+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.

+Early Buffer Allocation
+=======================
+
+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
+    than 0.  The max number is 4.
+
+  - erase
+
+    This will erase the all pre-allocated buffers which are not in
+    use.

+This document is a guide to using the emu10k1 based devices with JACK for low
+latency, multichannel recording functionality.  All of my recent work to allow
+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.

+
+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.

+   Audio transmission:
+
+     number of channels --  depends on transmission mode
+
+		The number of channels chosen is from 1..Nmax. The reason to
+		use for a lower number of channels is only resource allocation,
+		since unused DMA channels are disabled and less memory is
+		allocated. So also the throughput of the PCI system can be
+		scaled. (Only important for low performance boards).
+
+       Single Speed -- 1..64 channels 
+
+		 (Note: Choosing the 56channel mode for transmission or as
+		 receiver, only 56 are transmitted/received over the MADI, but
+		 all 64 channels are available for the mixer, so channel count
+		 for the driver)
+
+       Double Speed -- 1..32 channels
+
+		 Note: Choosing the 56-channel mode for
+		 transmission/receive-mode , only 28 are transmitted/received
+		 over the MADI, but all 32 channels are available for the mixer,

+
+     fragments -- 2

+     Hardware-pointer -- 2 Modi
+
+
+		 The Card supports the readout of the actual Buffer-pointer,
+		 where DMA reads/writes. Since of the bulk mode of PCI it is only
+		 64 Byte accurate. SO it is not really usable for the
+		 ALSA-mid-level functions (here the buffer-ID gives a better
+		 result), but if MMAP is used by the application. Therefore it
+		 can be configured at load-time with the parameter
+		 precise-pointer.
+
+
+		 (Hint: Experimenting I found that the pointer is maximum 64 to
+		 large never to small. So if you subtract 64 you always have a
+		 safe pointer for writing, which is used on this mode inside
+		 ALSA. In theory now you can get now a latency as low as 16
+		 Samples, which is a quarter of the interrupt possibilities.)
+
+       Precise Pointer -- off
+					interrupt used for pointer-calculation
+
+       Precise Pointer -- on

+
+   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

-Video4Linux provides the following sets of device files. These live on the
-character device formerly known as "/dev/bttv". /dev/bttv should be a
-symlink to /dev/video0 for most people. 
-<P>

-<P>
-Video4Linux programs open and scan the devices to find what they are looking
-for. Capability queries define what each interface supports. The 
-described API is only defined for video capture cards. The relevant subset
-applies to radio cards. Teletext interfaces talk the existing VTX API.
-<P>
-<H3>Capability Query Ioctl</H3>
-The <B>VIDIOCGCAP</B> ioctl call is used to obtain the capability
-information for a video device. The <b>struct video_capability</b> object
-passed to the ioctl is completed and returned. It contains the following
-information

-<P>
-The type field lists the capability flags for the device. These are
-as follows

-</TABLE>
-<P>
-The minimum and maximum sizes listed for a capture device do not imply all
-that all height/width ratios or sizes within the range are possible. A
-request to set a size will be honoured by the largest available capture
-size whose capture is no large than the requested rectangle in either
-direction. For example the quickcam has 3 fixed settings. 
-<P>
-<H3>Frame Buffer</H3>
-Capture cards that drop data directly onto the frame buffer must be told the
-base address of the frame buffer, its size and organisation. This is a 
-privileged ioctl and one that eventually X itself should set.
-<P>
-The <b>VIDIOCSFBUF</b> ioctl sets the frame buffer parameters for a capture
-card. If the card does not do direct writes to the frame buffer then this
-ioctl will be unsupported. The <b>VIDIOCGFBUF</b> ioctl returns the
-currently used parameters. The structure used in both cases is a 
-<b>struct video_buffer</b>.

-<P>
-Note that these values reflect the physical layout of the frame buffer. 
-The visible area may be smaller. In fact under XFree86 this is commonly the
-case. XFree86 DGA can provide the parameters required to set up this ioctl.
-Setting the base address to NULL indicates there is no physical frame buffer
-access.
-<P>
-<H3>Capture Windows</H3>
-The capture area is described by a <b>struct video_window</b>. This defines
-a capture area and the clipping information if relevant. The 
-<b>VIDIOCGWIN</b> ioctl recovers the current settings and the 
-<b>VIDIOCSWIN</b> sets new values. A successful call to <b>VIDIOCSWIN</b> 
-indicates that a suitable set of parameters have been chosen. They do not
-indicate that exactly what was requested was granted. The program should
-call <b>VIDIOCGWIN</b> to check if the nearest match was suitable. The
-<b>struct video_window</b> contains the following fields.

-<P>
-Merely setting the window does not enable capturing. Overlay capturing
-(i.e. PCI-PCI transfer to the frame buffer of the video card)
-is activated by passing the <b>VIDIOCCAPTURE</b> ioctl a value of 1, and
-disabled by passing it a value of 0. 
-<P>
-Some capture devices can capture a subfield of the image they actually see.
-This is indicated when VIDEO_TYPE_SUBCAPTURE is defined.

-the <b>struct video_channel</b> is filled in with information about the
-nature of the channel itself.
-<P>
-The <b>VIDIOCSCHAN</b> ioctl takes an integer argument and switches the
-capture to this input. It is not defined whether parameters such as colour
-settings or tuning are maintained across a channel switch. The caller should

-<H3>Reading Images</H3>
-Each call to the <b>read</b> syscall returns the next available image
-from the device. It is up to the caller to set format and size (using
-the VIDIOCSPICT and VIDIOCSWIN ioctls) and then to pass a suitable
-size buffer and length to the function. Not all devices will support
-read operations.
-<P>
-A second way to handle image capture is via the mmap interface if supported.
-To use the mmap interface a user first sets the desired image size and depth
-properties. Next the VIDIOCGMBUF ioctl is issued. This reports the size
-of buffer to mmap and the offset within the buffer for each frame. The
-number of frames supported is device dependent and may only be one. 
-<P>
-The video_mbuf structure contains the following fields
-<P>
-<TABLE>
-<TR><TD><b>size</b><TD>The number of bytes to map</TD>
-<TR><TD><b>frames</b><TD>The number of frames</TD>
-<TR><TD><b>offsets</b><TD>The offset of each frame</TD>
-</TABLE>
-<P>
-Once the mmap has been made the VIDIOCMCAPTURE ioctl starts the
-capture to a frame using the format and image size specified in the
-video_mmap (which should match or be below the initial query size).
-When the VIDIOCMCAPTURE ioctl returns the frame is <em>not</em>
-captured yet, the driver just instructed the hardware to start the
-capture.  The application has to use the VIDIOCSYNC ioctl to wait
-until the capture of a frame is finished.  VIDIOCSYNC takes the frame
-number you want to wait for as argument.
-<p>
-It is allowed to call VIDIOCMCAPTURE multiple times (with different
-frame numbers in video_mmap->frame of course) and thus have multiple
-outstanding capture requests.  A simple way do to double-buffering
-using this feature looks like this:
-<pre>
-/* setup everything */
-VIDIOCMCAPTURE(0)
-while (whatever) {
-   VIDIOCMCAPTURE(1)
-   VIDIOCSYNC(0)
-   /* process frame 0 while the hardware captures frame 1 */
-   VIDIOCMCAPTURE(0)
-   VIDIOCSYNC(1)
-   /* process frame 1 while the hardware captures frame 0 */
-}

+  bit [18]  IR_SMP_INT Set when 32 input samples have been collected over
+  gpio[16] pin into GP_SAMPLE register.
+
+What's missing from the data sheet:
+
+Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
+compat remote)
+set register 0x35C050 to  0xa80a80
+
+enable sampling
+set register 0x35C054 to 0x5
+
+Of course, enable the IRQ bit 18 in the interrupt mask register .(and
+provide for a handler)
+
+GP_SAMPLE register is at 0x35C058
+
+Bits are then right shifted into the GP_SAMPLE register at the specified
+rate; you get an interrupt when a full DWORD is recieved.
+You need to recover the actual RC5 bits out of the (oversampled) IR sensor
+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.

-Any w1 device must be connected to w1 bus master device - for example
-ds9490 usb device or w1-over-GPIO or RS232 converter.
-Driver for w1 bus master must provide several functions(you can find

-called by w1 core to send various commands over w1 bus(by default it is
-reset and search commands). When some device is found on the bus, w1 core
-checks if driver for it's family is loaded.
-If driver is loaded w1 core creates new w1_slave object and registers it
-in the system(creates some generic sysfs files(struct w1_family_ops in
-w1_family.h), notifies any registered listener and so on...).
-It is device driver's business to provide any communication method

-For example w1_therm driver(ds18?20 thermal sensor family driver)
-provides temperature reading function which is bound to ->rbin() method

+The 1-wire (w1) subsystem
+------------------------------------------------------------------
+The 1-wire bus is a simple master-slave bus that communicates via a single
+signal wire (plus ground, so two wires).
+
+Devices communicate on the bus by pulling the signal to ground via an open
+drain output and by sampling the logic level of the signal line.
+
+The w1 subsystem provides the framework for managing w1 masters and
+communication with slaves.
+
+All w1 slave devices must be connected to a w1 bus master device.
+
+Example w1 master devices:
+    DS9490 usb device
+    W1-over-GPIO
+    DS2482 (i2c to w1 bridge)
+    Emulated devices, such as a RS232 converter, parallel port adapter, etc
+
+
+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 sysfs interface
+------------------------------------------------------------------
+<xx-xxxxxxxxxxxxx> - a directory for a found device. The format is family-serial
+bus                - (standard) symlink to the w1 bus
+driver             - (standard) symlink to the w1 driver
+w1_master_attempts - the number of times a search was attempted
+w1_master_max_slave_count
+                   - the maximum slaves that may be attached to a master
+w1_master_name     - the name of the device (w1_bus_masterX)
+w1_master_search   - the number of searches left to do, -1=continual (default)
+w1_master_slave_count
+                   - the number of slaves found
+w1_master_slaves   - the names of the slaves, one per line
+w1_master_timeout  - the delay in seconds between searches
+
+If you have a w1 bus that never changes (you don't add or remove devices),
+you can set w1_master_search to a positive value to disable searches.
+
+
+w1 slave sysfs interface
+------------------------------------------------------------------
+bus                - (standard) symlink to the w1 bus
+driver             - (standard) symlink to the w1 driver
+name               - the device name, usually the same as the directory name
+w1_slave           - (optional) a binary file whose meaning depends on the
+                     family driver

-   3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-   denominator) divides a two-word unsigned integer, composed by the
-   integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
-   places the quotient in QUOTIENT and the remainder in REMAINDER.
-   HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
-   If, in addition, the most significant bit of DENOMINATOR must be 1,
-   then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
-
-   4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-   denominator).  Like udiv_qrnnd but the numbers are signed.  The
-   quotient is rounded towards 0.
-
-   5) count_leading_zeros(count, x) counts the number of zero-bits from
-   the msb to the first non-zero bit.  This is the number of steps X
-   needs to be shifted left to set the msb.  Undefined for X == 0.
-
-   6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
-   high_addend_2, low_addend_2) adds two two-word unsigned integers,
-   composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
-   LOW_ADDEND_2 respectively.  The result is placed in HIGH_SUM and
-   LOW_SUM.  Overflow (i.e. carry out) is not stored anywhere, and is
-   lost.
-
-   7) sub_ddmmss(high_difference, low_difference, high_minuend,
-   low_minuend, high_subtrahend, low_subtrahend) subtracts two
-   two-word unsigned integers, composed by HIGH_MINUEND_1 and
-   LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
-   respectively.  The result is placed in HIGH_DIFFERENCE and
-   LOW_DIFFERENCE.  Overflow (i.e. carry out) is not stored anywhere,
-   and is lost.
-
-   If any of these macros are left undefined for a particular CPU,
-   C macros are used.  */

+ * Jprobes (a.k.a. "jump probes" which is built on-top of kprobes) allow a
+ * probe to be inserted into the beginning of a function call.  The fundamental
+ * difference between a jprobe and a kprobe is the jprobe handler is executed
+ * in the same context as the target function, while the kprobe handlers
+ * are executed in interrupt context.
+ *
+ * For jprobes we initially gain control by placing a break point in the
+ * first instruction of the targeted function.  When we catch that specific
+ * break, we:
+ *        * set the return address to our jprobe_inst_return() function
+ *        * jump to the jprobe handler function
+ *
+ * Since we fixed up the return address, the jprobe handler will return to our
+ * jprobe_inst_return() function, giving us control again.  At this point we
+ * are back in the parents frame marker, so we do yet another call to our
+ * jprobe_break() function to fix up the frame marker as it would normally
+ * exist in the target function.
+ *
+ * Our jprobe_return function then transfers control back to kprobes.c by
+ * executing a break instruction using one of our reserved numbers.  When we
+ * catch that break in kprobes.c, we continue like we do for a normal kprobe
+ * by single stepping the emulated instruction, and then returning execution
+ * to the correct location.

+	  initially work for you.  It may help to enable device hotplugging

-	  It is possible to share one parallel port among several devices
-	  (e.g. printer and ZIP drive) and it is safe to compile the
-	  corresponding drivers into the kernel.  If you want to compile this
-	  driver as a module however, choose M here and read
-	  <file:Documentation/parport.txt>.  The module will be called lp.
-
-	  If you have several parallel ports, you can specify which ports to
-	  use with the "lp" kernel command line option.  (Try "man bootparam"
-	  or see the documentation of your boot loader (silo) about how to pass
-	  options to the kernel at boot time.)  The syntax of the "lp" command
-	  line option can be found in <file:drivers/char/lp.c>.
-

+ * to sleep.

+ * Double exception vector (Exceptions with PS.EXCM == 1)
+ * We get this exception when another exception occurs while were are
+ * already in an exception, such as window overflow/underflow exception,
+ * or 'expected' exceptions, for example memory exception when we were trying
+ * to read data from an invalid address in user space.
+ *
+ * Note that this vector is never invoked for level-1 interrupts, because such
+ * interrupts are disabled (masked) when PS.EXCM is set.
+ *
+ * We decode the exception and take the appropriate action.  However, the
+ * double exception vector is much more careful, because a lot more error
+ * cases go through the double exception vector than through the user and
+ * kernel exception vectors.
+ *
+ * Occasionally, the kernel expects a double exception to occur.  This usually
+ * happens when accessing user-space memory with the user's permissions
+ * (l32e/s32e instructions).  The kernel state, though, is not always suitable
+ * for immediate transfer of control to handle_double, where "normal" exception
+ * processing occurs. Also in kernel mode, TLB misses can occur if accessing
+ * vmalloc memory, possibly requiring repair in a double exception handler.
+ *
+ * The variable at TABLE_FIXUP offset from the pointer in EXCSAVE_1 doubles as
+ * a boolean variable and a pointer to a fixup routine. If the variable
+ * EXC_TABLE_FIXUP is non-zero, this handler jumps to that address. A value of
+ * zero indicates to use the default kernel/user exception handler.
+ * There is only one exception, when the value is identical to the exc_table
+ * label, the kernel is in trouble. This mechanism is used to protect critical
+ * sections, mainly when the handler writes to the stack to assert the stack
+ * pointer is valid. Once the fixup/default handler leaves that area, the
+ * EXC_TABLE_FIXUP variable is reset to the fixup handler or zero.
+ *
+ * Procedures wishing to use this mechanism should set EXC_TABLE_FIXUP to the
+ * nonzero address of a fixup routine before it could cause a double exception
+ * and reset it before it returns.
+ *
+ * Some other things to take care of when a fast exception handler doesn't
+ * specify a particular fixup handler but wants to use the default handlers:
+ *
+ *  - The original stack pointer (in a1) must not be modified. The fast
+ *    exception handler should only use a2 as the stack pointer.
+ *
+ *  - If the fast handler manipulates the stack pointer (in a2), it has to
+ *    register a valid fixup handler and cannot use the default handlers.
+ *
+ *  - The handler can use any other generic register from a3 to a15, but it
+ *    must save the content of these registers to stack (PT_AREG3...PT_AREGx)
+ *
+ *  - These registers must be saved before a double exception can occur.
+ *
+ *  - If we ever implement handling signals while in double exceptions, the
+ *    number of registers a fast handler has saved (excluding a0 and a1) must
+ *    be written to  PT_AREG1. (1 if only a3 is used, 2 for a3 and a4, etc. )
+ *
+ * The fixup handlers are special handlers:
+ *
+ *  - Fixup entry conditions differ from regular exceptions:
+ *
+ *	a0:	   DEPC
+ *	a1: 	   a1
+ *	a2:	   trashed, original value in EXC_TABLE_DOUBLE_A2
+ *	a3:	   exctable
+ *	depc:	   a0
+ *	excsave_1: a3
+ *
+ *  - When the kernel enters the fixup handler, it still assumes it is in a
+ *    critical section, so EXC_TABLE_FIXUP variable is set to exc_table.
+ *    The fixup handler, therefore, has to re-register itself as the fixup
+ *    handler before it returns from the double exception.
+ *
+ *  - Fixup handler can share the same exception frame with the fast handler.
+ *    The kernel stack pointer is not changed when entering the fixup handler.
+ *

+ *    the fixup handler.
+ *
+ * In case of a critical condition where the kernel cannot recover, we jump
+ * to unrecoverable_exception with the following entry conditions.
+ * All registers a0...a15 are unchanged from the last exception, except:

+ *
+ * This function is intended to do the same thing as the standard
+ * library function memcpy() (or bcopy()) for most cases.
+ * However, where the source and/or destination references
+ * an instruction RAM or ROM or a data RAM or ROM, that
+ * source and/or destination will always be accessed with
+ * 32-bit load and store instructions (as required for these
+ * types of devices).
+ *
+ * !!!!!!!  XTFIXME:
+ * !!!!!!!  Handling of IRAM/IROM has not yet
+ * !!!!!!!  been implemented.
+ *
+ * The bcopy version is provided here to avoid the overhead
+ * of an extra call, for callers that require this convention.
+ *
+ * The (general case) algorithm is as follows:
+ *   If destination is unaligned, align it by conditionally
+ *     copying 1 and 2 bytes.
+ *   If source is aligned,
+ *     do 16 bytes with a loop, and then finish up with
+ *     8, 4, 2, and 1 byte copies conditional on the length;
+ *   else (if source is unaligned),
+ *     do the same, but use SRC to align the source data.
+ *   This code tries to use fall-through branches for the common
+ *     case of aligned source and destination and multiple
+ *     of 4 (or 8) length.
+ *
+ * Register use:
+ *	a0/ return address
+ *	a1/ stack pointer
+ *	a2/ return value
+ *	a3/ src
+ *	a4/ length

+
+    Copyright (C) 2005 Ben Gardner <bgardner@wabtec.com>
+
+    Based on i2c/chips/eeprom.c
+
+    The MAX6875 has two EEPROM sections: config and user.
+    At reset, the config EEPROM is read into the registers.
+
+    This driver make 3 binary files available in sysfs:
+      reg_config    - direct access to the registers
+      eeprom_config - acesses configuration eeprom space
+      eeprom_user   - free for application use
+
+    In our application, we put device serial & model numbers in user eeprom.
+
+    Notes:
+      1) The datasheet says that register 0x44 / EEPROM 0x8044 should NOT
+         be overwritten, so the driver explicitly prevents that.
+      2) It's a good idea to keep the config (0x45) locked in config EEPROM.
+         You can temporarily enable config writes by changing register 0x45.

+ *
+ *  May be copied or modified under the terms of the GNU General Public License
+ *  Based in part on the ITE vendor provided SCSI driver.

+ *  Documentation available from
+ * 	http://www.ite.com.tw/pc/IT8212F_V04.pdf
+ *  Some other documents are NDA.
+ *
+ *  The ITE8212 isn't exactly a standard IDE controller. It has two
+ *  modes. In pass through mode then it is an IDE controller. In its smart
+ *  mode its actually quite a capable hardware raid controller disguised
+ *  as an IDE controller. Smart mode only understands DMA read/write and
+ *  identify, none of the fancier commands apply. The IT8211 is identical
+ *  in other respects but lacks the raid mode.
+ *
+ *  Errata:
+ *  o	Rev 0x10 also requires master/slave hold the same DMA timings and
+ *	cannot do ATAPI MWDMA.
+ *  o	The identify data for raid volumes lacks CHS info (technically ok)
+ *	but also fails to set the LBA28 and other bits. We fix these in
+ *	the IDE probe quirk code.
+ *  o	If you write LBA48 sized I/O's (ie > 256 sector) in smart mode
+ *	raid then the controller firmware dies
+ *  o	Smart mode without RAID doesn't clear all the necessary identify
+ *	bits to reduce the command set to the one used
+ *
+ *  This has a few impacts on the driver
+ *  - In pass through mode we do all the work you would expect
+ *  - In smart mode the clocking set up is done by the controller generally
+ *    but we must watch the other limits and filter.
+ *  - There are a few extra vendor commands that actually talk to the
+ *    controller but only work PIO with no IRQ.
+ *
+ *  Vendor areas of the identify block in smart mode are used for the
+ *  timing and policy set up. Each HDD in raid mode also has a serial
+ *  block on the disk. The hardware extra commands are get/set chip status,
+ *  rebuild, get rebuild status.
+ *
+ *  In Linux the driver supports pass through mode as if the device was
+ *  just another IDE controller. If the smart mode is running then
+ *  volumes are managed by the controller firmware and each IDE "disk"
+ *  is a raid volume. Even more cute - the controller can do automated
+ *  hotplug and rebuild.
+ *
+ *  The pass through controller itself is a little demented. It has a
+ *  flaw that it has a single set of PIO/MWDMA timings per channel so
+ *  non UDMA devices restrict each others performance. It also has a
+ *  single clock source per channel so mixed UDMA100/133 performance
+ *  isn't perfect and we have to pick a clock. Thankfully none of this
+ *  matters in smart mode. ATAPI DMA is not currently supported.
+ *
+ *  It seems the smart mode is a win for RAID1/RAID10 but otherwise not.
+ *
+ *  TODO
+ *	-	ATAPI UDMA is ok but not MWDMA it seems
+ *	-	RAID configuration ioctls
+ *	-	Move to libata once it grows up

-  hdlc_decode - decodes HDLC frames from a transparent bit stream.

-  the frame is found, the bit stuffing is removed (0 after 5 1's).
-  When a new flag is found, the complete frame has been received
-  and the CRC is checked.
-  If a valid frame is found, the function returns the frame length 
-  excluding the CRC with the bit HDLC_END_OF_FRAME set.
-  If the beginning of a valid frame is found, the function returns
-  the length. 
-  If a framing error is found (too many 1s and not a flag) the function 
-  returns the length with the bit HDLC_FRAMING_ERROR set.
-  If a CRC error is found the function returns the length with the
-  bit HDLC_CRC_ERROR set.
-  If the frame length exceeds the destination buffer size, the function
-  returns the length with the bit HDLC_LENGTH_ERROR set.

- * FixZeroBug....Works around a bug in the SCC receving channel.

- * (most versions -- also with some Heathrow and Hydra ASICs) where a zero
- * at the input to the receiver becomes 'stuck' and locks up the receiver.
- * This problem can occur as a result of a zero bit at the receiver input
- * coincident with any of the following events:
- *
- *	The SCC is initialized (hardware or software).
- *	A framing error is detected.
- *	The clocking option changes from synchronous or X1 asynchronous
- *		clocking to X16, X32, or X64 asynchronous clocking.
- *	The decoding mode is changed among NRZ, NRZI, FM0, or FM1.
- *
- * This workaround attempts to recover from the lockup condition by placing
- * the SCC in synchronous loopback mode with a fast clock before programming
- * any of the asynchronous modes.

+ *  This driver is "hard-coded" to be used with the 1st generation of

+ *  The driver works also with QAM64 DVB-C, but had an unreasonable high
+ *  UNC. (Tested with the Air2PC ATSC 1st generation)
+ *
+ *  You'll need a firmware for this driver in order to get it running. It is

- *
- * v0.06c -> v0.06d - 6/7/2001 - David Gibson
- *      o Change a bunch of KERN_INFO messages to KERN_DEBUG, as per Linus'
- *        wishes to reduce the number of unnecessary messages.

- *	o Merged fixes for v0.08 Prism 2 firmware from William Waghorn
- *	  <willwaghorn AT yahoo.co.uk>
- *	o Slight cleanup/re-arrangement of firmware detection code.
- *
- * v0.06d -> v0.06e - 1/8/2001 - David Gibson
- *	o Removed some redundant global initializers (orinoco_cs.c).
- *	o Added some module metadata
- *
- * v0.06e -> v0.06f - 14/8/2001 - David Gibson
- *	o Wording fix to license
- *	o Added a 'use_alternate_encaps' module parameter for APs which need an
- *	  oui of 00:00:00.  We really need a better way of handling this, but
- *	  the module flag is better than nothing for now.
- *
- * v0.06f -> v0.07 - 20/8/2001 - David Gibson
- *	o Removed BAP error retries from hermes_bap_seek().  For Tx we now
- *	  let the upper layers handle the retry, we retry explicitly in the
- *	  Rx path, but don't make as much noise about it.
- *	o Firmware detection cleanups.
- *
- * v0.07 -> v0.07a - 1/10/3001 - Jean II
- *	o Add code to read Symbol firmware revision, inspired by latest code
- *	  in Spectrum24 by Lee John Keyser-Allen - Thanks Lee !
- *	o Thanks to Jared Valentine <hidden AT xmission.com> for "providing" me
- *	  a 3Com card with a recent firmware, fill out Symbol firmware
- *	  capabilities of latest rev (2.20), as well as older Symbol cards.
- *	o Disable Power Management in newer Symbol firmware, the API 
- *	  has changed (documentation needed).
- *
- * v0.07a -> v0.08 - 3/10/2001 - David Gibson
- *	o Fixed a possible buffer overrun found by the Stanford checker (in
- *	  dldwd_ioctl_setiwencode()).  Can only be called by root anyway, so not
- *	  a big problem.
- *	o Turned has_big_wep on for Intersil cards.  That's not true for all of
- *	  them but we should at least let the capable ones try.
- *	o Wait for BUSY to clear at the beginning of hermes_bap_seek().  I
- *	  realized that my assumption that the driver's serialization
- *	  would prevent the BAP being busy on entry was possibly false, because
- *	  things other than seeks may make the BAP busy.
- *	o Use "alternate" (oui 00:00:00) encapsulation by default.
- *	  Setting use_old_encaps will mimic the old behaviour, but I think we
- *	  will be able to eliminate this.
- *	o Don't try to make __initdata const (the version string).  This can't
- *	  work because of the way the __initdata sectioning works.
- *	o Added MODULE_LICENSE tags.
- *	o Support for PLX (transparent PCMCIA->PCI bridge) cards.
- *	o Changed to using the new type-fascist min/max.
- *
- * v0.08 -> v0.08a - 9/10/2001 - David Gibson
- *	o Inserted some missing acknowledgements/info into the Changelog.
- *	o Fixed some bugs in the normalization of signal level reporting.
- *	o Fixed bad bug in WEP key handling on Intersil and Symbol firmware,
- *	  which led to an instant crash on big-endian machines.
- *
- * v0.08a -> v0.08b - 20/11/2001 - David Gibson
- *	o Lots of cleanup and bugfixes in orinoco_plx.c
- *	o Cleanup to handling of Tx rate setting.
- *	o Removed support for old encapsulation method.
- *	o Removed old "dldwd" names.
- *	o Split RID constants into a new file hermes_rid.h
- *	o Renamed RID constants to match linux-wlan-ng and prism2.o
- *	o Bugfixes in hermes.c
- *	o Poke the PLX's INTCSR register, so it actually starts
- *	  generating interrupts.  These cards might actually work now.
- *	o Update to wireless extensions v12 (Jean II)
- *	o Support for tallies and inquire command (Jean II)
- *	o Airport updates for newer PPC kernels (BenH)
- *
- * v0.08b -> v0.09 - 21/12/2001 - David Gibson
- *	o Some new PCI IDs for PLX cards.
- *	o Removed broken attempt to do ALLMULTI reception.  Just use
- *	  promiscuous mode instead
- *	o Preliminary work for list-AP (Jean II)
- *	o Airport updates from (BenH)
- *	o Eliminated racy hw_ready stuff
- *	o Fixed generation of fake events in irq handler.  This should
- *	  finally kill the EIO problems (Jean II & dgibson)
- *	o Fixed breakage of bitrate set/get on Agere firmware (Jean II)
- *
- * v0.09 -> v0.09a - 2/1/2002 - David Gibson
- *	o Fixed stupid mistake in multicast list handling, triggering
- *	  a BUG()
- *
- * v0.09a -> v0.09b - 16/1/2002 - David Gibson
- *	o Fixed even stupider mistake in new interrupt handling, which
- *	  seriously broke things on big-endian machines.
- *	o Removed a bunch of redundant includes and exports.
- *	o Removed a redundant MOD_{INC,DEC}_USE_COUNT pair in airport.c
- *	o Don't attempt to do hardware level multicast reception on
- *	  Intersil firmware, just go promisc instead.
- *	o Typo fixed in hermes_issue_cmd()
- *	o Eliminated WIRELESS_SPY #ifdefs
- *	o Status code reported on Tx exceptions
- *	o Moved netif_wake_queue() from ALLOC interrupts to TX and TXEXC
- *	  interrupts, which should fix the timeouts we're seeing.
- *
- * v0.09b -> v0.10 - 25 Feb 2002 - David Gibson
- *	o Removed nested structures used for header parsing, so the
- *	  driver should now work without hackery on ARM
- *	o Fix for WEP handling on Intersil (Hawk Newton)
- *	o Eliminated the /proc/hermes/ethXX/regs debugging file.  It
- *	  was never very useful.
- *	o Make Rx errors less noisy.
- *
- * v0.10 -> v0.11 - 5 Apr 2002 - David Gibson
- *	o Laid the groundwork in hermes.[ch] for devices which map
- *	  into PCI memory space rather than IO space.
- *	o Fixed bug in multicast handling (cleared multicast list when
- *	  leaving promiscuous mode).
- *	o Relegated Tx error messages to debug.
- *	o Cleaned up / corrected handling of allocation lengths.
- *	o Set OWNSSID in IBSS mode for WinXP interoperability (jimc).
- *	o Change to using alloc_etherdev() for structure allocations. 
- *	o Check for and drop undersized packets.
- *	o Fixed a race in stopping/waking the queue.  This should fix
- *	  the timeout problems (Pavel Roskin)
- *	o Reverted to netif_wake_queue() on the ALLOC event.
- *	o Fixes for recent Symbol firmwares which lack AP density
- *	  (Pavel Roskin).
- *
- * v0.11 -> v0.11a - 29 Apr 2002 - David Gibson
- *	o Handle different register spacing, necessary for Prism 2.5
- *	  PCI adaptors (Steve Hill).
- *	o Cleaned up initialization of card structures in orinoco_cs
- *	  and airport.  Removed card->priv field.
- *	o Make response structure optional for hermes_docmd_wait()
- *	  Pavel Roskin)
- *	o Added PCI id for Nortel emobility to orinoco_plx.c.
- *	o Cleanup to handling of Symbol's allocation bug. (Pavel Roskin)
- *	o Cleanups to firmware capability detection.
- *	o Arrange for orinoco_pci.c to override firmware detection.
- *	  We should be able to support the PCI Intersil cards now.
- *	o Cleanup handling of reset_cor and hard_reset (Pavel Roskin).
- *	o Remove erroneous use of USER_BAP in the TxExc handler (Jouni
- *	  Malinen).
- *	o Makefile changes for better integration into David Hinds
- *	  pcmcia-cs package.
- *
- * v0.11a -> v0.11b - 1 May 2002 - David Gibson
- *	o Better error reporting in orinoco_plx_init_one()
- *	o Fixed multiple bad kfree() bugs introduced by the
- *	  alloc_orinocodev() changes.
- *
- * v0.11b -> v0.12 - 19 Jun 2002 - David Gibson
- *	o Support changing the MAC address.
- *	o Correct display of Intersil firmware revision numbers.
- *	o Entirely revised locking scheme.  Should be both simpler and
- *	   better.
- *	o Merged some common code in orinoco_plx, orinoco_pci and
- *	  airport by creating orinoco_default_{open,stop,reset}()
- *	  which are used as the dev->open, dev->stop, priv->reset
- *	  callbacks if none are specified when alloc_orinocodev() is
- *	  called.
- *	o Removed orinoco_plx_interrupt() and orinoco_pci_interrupt().
- *	  They didn't do anything.
- *
- * v0.12 -> v0.12a - 4 Jul 2002 - David Gibson
- *	o Some rearrangement of code.
- *	o Numerous fixups to locking and rest handling, particularly
- *	  for PCMCIA.
- *	o This allows open and stop net_device methods to be in
- *	  orinoco.c now, rather than in the init modules.
- *	o In orinoco_cs.c link->priv now points to the struct
- *	  net_device not to the struct orinoco_private.
- *	o Added a check for undersized SNAP frames, which could cause
- *	  crashes.
- *
- * v0.12a -> v0.12b - 11 Jul 2002 - David Gibson
- *	o Fix hw->num_init testing code, so num_init is actually
- *	  incremented.
- *	o Fix very stupid bug in orinoco_cs which broke compile with
- *	  CONFIG_SMP.
- *	o Squashed a warning.
- *
- * v0.12b -> v0.12c - 26 Jul 2002 - David Gibson
- *	o Change to C9X style designated initializers.
- *	o Add support for 3Com AirConnect PCI.
- *	o No longer ignore the hard_reset argument to
- *	  alloc_orinocodev().  Oops.
- *
- * v0.12c -> v0.13beta1 - 13 Sep 2002 - David Gibson
- *	o Revert the broken 0.12* locking scheme and go to a new yet
- *	  simpler scheme.
- *	o Do firmware resets only in orinoco_init() and when waking
- *	  the card from hard sleep.
- *
- * v0.13beta1 -> v0.13 - 27 Sep 2002 - David Gibson
- *	o Re-introduced full resets (via schedule_task()) on Tx
- *	  timeout.
- *
- * v0.13 -> v0.13a - 30 Sep 2002 - David Gibson
- *	o Minor cleanups to info frame handling.  Add basic support
- *	  for linkstatus info frames.
- *	o Include required kernel headers in orinoco.h, to avoid
- *	  compile problems.
- *
- * v0.13a -> v0.13b - 10 Feb 2003 - David Gibson
- *	o Implemented hard reset for Airport cards
- *	o Experimental suspend/resume implementation for orinoco_pci
- *	o Abolished /proc debugging support, replaced with a debugging
- *	  iwpriv.  Now it's ugly and simple instead of ugly and complex.
- *	o Bugfix in hermes.c if the firmware returned a record length
- *	  of 0, we could go clobbering memory.
- *	o Bugfix in orinoco_stop() - it used to fail if hw_unavailable
- *	  was set, which was usually true on PCMCIA hot removes.
- * 	o Track LINKSTATUS messages, silently drop Tx packets before
- * 	  we are connected (avoids confusing the firmware), and only
- * 	  give LINKSTATUS printk()s if the status has changed.
- *
- * v0.13b -> v0.13c - 11 Mar 2003 - David Gibson
- *	o Cleanup: use dev instead of priv in various places.
- *	o Bug fix: Don't ReleaseConfiguration on RESET_PHYSICAL event
- *	  if we're in the middle of a (driver initiated) hard reset.
- *	o Bug fix: ETH_ZLEN is supposed to include the header
- *	  (Dionysus Blazakis & Manish Karir)
- *	o Convert to using workqueues instead of taskqueues (and
- *	  backwards compatibility macros for pre 2.5.41 kernels).
- *	o Drop redundant (I think...) MOD_{INC,DEC}_USE_COUNT in
- *	  airport.c
- *	o New orinoco_tmd.c init module from Joerg Dorchain for
- *	  TMD7160 based PCI to PCMCIA bridges (similar to
- *	  orinoco_plx.c).
- *
- * v0.13c -> v0.13d - 22 Apr 2003 - David Gibson
- *	o Make hw_unavailable a counter, rather than just a flag, this
- *	  is necessary to avoid some races (such as a card being
- *	  removed in the middle of orinoco_reset().
- *	o Restore Release/RequestConfiguration in the PCMCIA event handler
- *	  when dealing with a driver initiated hard reset.  This is
- *	  necessary to prevent hangs due to a spurious interrupt while
- *	  the reset is in progress.
- *	o Clear the 802.11 header when transmitting, even though we
- *	  don't use it.  This fixes a long standing bug on some
- *	  firmwares, which seem to get confused if that isn't done.
- *	o Be less eager to de-encapsulate SNAP frames, only do so if
- *	  the OUI is 00:00:00 or 00:00:f8, leave others alone.  The old
- *	  behaviour broke CDP (Cisco Discovery Protocol).
- *	o Use dev instead of priv for free_irq() as well as
- *	  request_irq() (oops).
- *	o Attempt to reset rather than giving up if we get too many
- *	  IRQs.
- *	o Changed semantics of __orinoco_down() so it can be called
- *	  safely with hw_unavailable set.  It also now clears the
- *	  linkstatus (since we're going to have to reassociate).
- *
- * v0.13d -> v0.13e - 12 May 2003 - David Gibson
- *	o Support for post-2.5.68 return values from irq handler.
- *	o Fixed bug where underlength packets would be double counted
- *	  in the rx_dropped statistics.
- *	o Provided a module parameter to suppress linkstatus messages.
- *
- * v0.13e -> v0.14alpha1 - 30 Sep 2003 - David Gibson
- *	o Replaced priv->connected logic with netif_carrier_on/off()
- *	  calls.
- *	o Remove has_ibss_any and never set the CREATEIBSS RID when
- *	  the ESSID is empty.  Too many firmwares break if we do.
- *	o 2.6 merges: Replace pdev->slot_name with pci_name(), remove
- *	  __devinitdata from PCI ID tables, use free_netdev().
- *	o Enabled shared-key authentication for Agere firmware (from
- *	  Robert J. Moore <Robert.J.Moore AT allanbank.com>
- *	o Move netif_wake_queue() (back) to the Tx completion from the
- *	  ALLOC event.  This seems to prevent/mitigate the rolling
- *	  error -110 problems at least on some Intersil firmwares.
- *	  Theoretically reduces performance, but I can't measure it.
- *	  Patch from Andrew Tridgell <tridge AT samba.org>
- *
- * v0.14alpha1 -> v0.14alpha2 - 20 Oct 2003 - David Gibson
- *	o Correctly turn off shared-key authentication when requested
- *	  (bugfix from Robert J. Moore).
- *	o Correct airport sleep interfaces for current 2.6 kernels.
- *	o Add code for key change without disabling/enabling the MAC
- *	  port.  This is supposed to allow 802.1x to work sanely, but
- *	  doesn't seem to yet.
- *
  * TODO
- *	o New wireless extensions API (patch from Moustafa
- *	  Youssef, updated by Jim Carter and Pavel Roskin).
  *	o Handle de-encapsulation within network layer, provide 802.11
  *	  headers (patch from Thomas 'Dent' Mirlacher)
- *	o RF monitor mode support
  *	o Fix possible races in SPY handling.
  *	o Disconnect wireless extensions from fundamental configuration.
  *	o (maybe) Software WEP support (patch from Stano Meduna).

-    bind_request() and bind_device() are merged by now. Register_client()
-    is called right at the end of bind_request(), during the driver's
-    ->attach() call. Individual descriptions:
-
-    bind_request() connects a socket to a particular client driver.
-    It looks up the specified device ID in the list of registered
-    drivers, binds it to the socket, and tries to create an instance
-    of the device.  unbind_request() deletes a driver instance.
-    
-    Bind_device() associates a device driver with a particular socket.
-    It is normally called by Driver Services after it has identified
-    a newly inserted card.  An instance of that driver will then be
-    eligible to register as a client of this socket.
-
-    Register_client() uses the dev_info_t handle to match the
-    caller with a socket.  The driver must have already been bound
-    to a socket with bind_device() -- in fact, bind_device()
-    allocates the client structure that will be used.

+
+    bind_request() connects a socket to a particular client driver.
+    It looks up the specified device ID in the list of registered
+    drivers, binds it to the socket, and tries to create an instance
+    of the device.  unbind_request() deletes a driver instance.
+
+    Bind_device() associates a device driver with a particular socket.
+    It is normally called by Driver Services after it has identified
+    a newly inserted card.  An instance of that driver will then be
+    eligible to register as a client of this socket.
+
+    Register_client() uses the dev_info_t handle to match the
+    caller with a socket.  The driver must have already been bound
+    to a socket with bind_device() -- in fact, bind_device()
+    allocates the client structure that will be used.

+ *
+ *  1.7+:	- See the check-in logs
+ *
+ *  1.6:	- No longer opens a connection if the firmware is not loaded
+ *  		- Added support for the speedtouch 330
+ *  		- Removed the limit on the number of devices
+ *  		- Module now autoloads on device plugin
+ *  		- Merged relevant parts of sarlib
+ *  		- Replaced the kernel thread with a tasklet
+ *  		- New packet transmission code
+ *  		- Changed proc file contents
+ *  		- Fixed all known SMP races
+ *  		- Many fixes and cleanups
+ *  		- Various fixes by Oliver Neukum (oliver@neukum.name)
+ *
+ *  1.5A:	- Version for inclusion in 2.5 series kernel
+ *		- Modifications by Richard Purdie (rpurdie@rpsys.net)
+ *		- made compatible with kernel 2.5.6 onwards by changing
+ *		usbatm_usb_send_data_context->urb to a pointer and adding code
+ *		to alloc and free it
+ *		- remove_wait_queue() added to usbatm_atm_processqueue_thread()
+ *
+ *  1.5:	- fixed memory leak when atmsar_decode_aal5 returned NULL.
+ *		(reported by stephen.robinson@zen.co.uk)
+ *
+ *  1.4:	- changed the spin_lock() under interrupt to spin_lock_irqsave()
+ *		- unlink all active send urbs of a vcc that is being closed.
+ *
+ *  1.3.1:	- added the version number
+ *
+ *  1.3:	- Added multiple send urb support
+ *		- fixed memory leak and vcc->tx_inuse starvation bug
+ *		  when not enough memory left in vcc.
+ *
+ *  1.2:	- Fixed race condition in usbatm_usb_send_data()
+ *  1.1:	- Turned off packet debugging

+ *
+ * This file is subject to the terms and conditions of the GNU General Public

+ * more details.
+ *
+ * Layout is based on skeletonfb.c by James Simmons and Geert Uytterhoeven.
+ *
+ * This driver was written to be used with the Arc LCD board. Arc uses a
+ * set of KS108 chips that control individual 64x64 LCD matrices. The board
+ * can be paneled in a variety of setups such as 2x1=128x64, 4x4=256x256 and
+ * so on. The interface between the board and the host is TTL based GPIO. The
+ * GPIO requirements are 8 writable data lines and 4+n lines for control. On a
+ * GPIO-less system, the board can be tested by connecting the respective sigs
+ * up to a parallel port connector. The driver requires the IO addresses for
+ * data and control GPIO at load time. It is unable to probe for the
+ * existence of the LCD so it must be told at load time whether it should
+ * be enabled or not.
+ *
+ * Todo:
+ * - testing with 4x4
+ * - testing with interrupt hw
+ *
+ * General notes:
+ * - User must set tuhold. It's in microseconds. According to the 108 spec,
+ *   the hold time is supposed to be at least 1 microsecond.
+ * - User must set num_cols=x num_rows=y, eg: x=2 means 128
+ * - User must set arcfb_enable=1 to enable it
+ * - User must set dio_addr=0xIOADDR cio_addr=0xIOADDR

-	  This is support for devfs, a virtual file system (like /proc) which
-	  provides the file system interface to device drivers, normally found
-	  in /dev. Devfs does not depend on major and minor number
-	  allocations. Device drivers register entries in /dev which then
-	  appear automatically, which means that the system administrator does
-	  not have to create character and block special device files in the
-	  /dev directory using the mknod command (or MAKEDEV script) anymore.
-
-	  This is work in progress. If you want to use this, you *must* read
-	  the material in <file:Documentation/filesystems/devfs/>, especially
-	  the file README there.
-
-	  Note that devfs no longer manages /dev/pts!  If you are using UNIX98
-	  ptys, you will also need to mount the /dev/pts filesystem (devpts).
-
-	  Note that devfs has been obsoleted by udev,
-	  <http://www.kernel.org/pub/linux/utils/kernel/hotplug/>.

+ *  - The ACL_MASK entry in such minimal ACLs always has the same
+ *    permissions as the ACL_GROUP_OBJ entry. (In extended ACLs
+ *    the ACL_MASK and ACL_GROUP_OBJ entries may differ.)
+ *  - The identifier fields of the ACL_USER_OBJ and ACL_GROUP_OBJ
+ *    entries contain the identifiers of the owner and owning group.
+ *    (In POSIX ACLs we always set them to ACL_UNDEFINED_ID).
+ *  - ACL entries in the kernel are kept sorted in ascending order
+ *    of (e_tag, e_id). Solaris ACLs are unsorted.

+ * Encode and decode a swap entry.
+ * Each PTE in a process VM's page table is either:
+ *   "present" -- valid and not swapped out, protection bits are meaningful;
+ *   "not present" -- which further subdivides in these two cases:
+ *      "none" -- no mapping at all; identified by pte_none(), set by pte_clear(
+ *      "swapped out" -- the page is swapped out, and the SWP macros below
+ *                      are used to store swap file info in the PTE itself.
+ *
+ * In the Xtensa processor MMU, any PTE entries in user space (or anywhere
+ * in virtual memory that can map differently across address spaces)
+ * must have a correct ring value that represents the RASID field that
+ * is changed when switching address spaces.  Eg. such PTE entries cannot
+ * be set to ring zero, because that can cause a (global) kernel ASID
+ * entry to be created in the TLBs (even with invalid cache attribute),
+ * potentially causing a multihit exception when going back to another
+ * address space that mapped the same virtual address at another ring.
+ *
+ * SO: we avoid using ring bits (_PAGE_RING_MASK) in "not present" PTEs.
+ * We also avoid using the _PAGE_VALID bit which must be zero for non-present
+ * pages.
+ *
+ * We end up with the following available bits:  1..3 and 7..31.
+ * We don't bother with 1..3 for now (we can use them later if needed),
+ * and chose to allocate 6 bits for SWP_TYPE and the remaining 19 bits
+ * for SWP_OFFSET.  At least 5 bits are needed for SWP_TYPE, because it
+ * is currently implemented as an index into swap_info[MAX_SWAPFILES]
+ * and MAX_SWAPFILES is currently defined as 32 in <linux/swap.h>.
+ * However, for some reason all other architectures in the 2.4 kernel
+ * reserve either 6, 7, or 8 bits so I'll not detract from that for now.  :)
+ * SWP_OFFSET is an offset into the swap file in page-size units, so
+ * with 4 kB pages, 19 bits supports a maximum swap file size of 2 GB.
+ *
+ * FIXME:  2 GB isn't very big.  Other bits can be used to allow
+ * larger swap sizes.  In the meantime, it appears relatively easy to get
+ * around the 2 GB limitation by simply using multiple swap files.

+ * (beyond the front-end that knows of __asm__ statements and other
+ * such GNU Extensions to C) can modify the register selection for
+ * containment of C variables.
+ *
+ * xt-xcc cannot modify the contents of a single __asm__ statement, so
+ * we create single-asm versions of the syscall macros that are
+ * suitable and optimal for both xt-xcc and gcc.
+ *
+ * Linux takes system-call arguments in registers.  The following
+ * design is optimized for user-land apps (e.g., glibc) which
+ * typically have a function wrapper around the "syscall" assembly
+ * instruction.  It satisfies the Xtensa ABI while minizing argument
+ * shifting.
+ *
+ * The Xtensa ABI and software conventions require the system-call
+ * number in a2.  If an argument exists in a2, we move it to the next
+ * available register.  Note that for improved efficiency, we do NOT
+ * shift all parameters down one register to maintain the original
+ * order.
+ *
+ * At best case (zero arguments), we just write the syscall number to
+ * a2.  At worst case (1 to 6 arguments), we move the argument in a2
+ * to the next available register, then write the syscall number to
+ * a2.
+ *
+ * For clarity, the following truth table enumerates all possibilities.
+ *

+/*
+ *  General notes on MMU parameters.
+ *
+ *  Terminology:
+ *	ASID = address-space ID (acts as an "extension" of virtual addresses)
+ *	VPN  = virtual page number
+ *	PPN  = physical page number
+ *	CA   = encoded cache attribute (access modes)
+ *	TLB  = translation look-aside buffer (term is stretched somewhat here)
+ *	I    = instruction (fetch accesses)
+ *	D    = data (load and store accesses)
+ *	way  = each TLB (ITLB and DTLB) consists of a number of "ways"
+ *		that simultaneously match the virtual address of an access;
+ *		a TLB successfully translates a virtual address if exactly
+ *		one way matches the vaddr; if none match, it is a miss;
+ *		if multiple match, one gets a "multihit" exception;
+ *		each way can be independently configured in terms of number of
+ *		entries, page sizes, which fields are writable or constant, etc.
+ *	set  = group of contiguous ways with exactly identical parameters
+ *	ARF  = auto-refill; hardware services a 1st-level miss by loading a PTE
+ *		from the page table and storing it in one of the auto-refill ways;
+ *		if this PTE load also misses, a miss exception is posted for s/w.
+ *	min-wired = a "min-wired" way can be used to map a single (minimum-sized)
+ * 		page arbitrarily under program control; it has a single entry,
+ *		is non-auto-refill (some other way(s) must be auto-refill),
+ *		all its fields (VPN, PPN, ASID, CA) are all writable, and it
+ *		supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current
+ *		restriction is that this be the only page size it supports).
+ *
+ *  TLB way entries are virtually indexed.
+ *  TLB ways that support multiple page sizes:
+ *	- must have all writable VPN and PPN fields;
+ *	- can only use one page size at any given time (eg. setup at startup),
+ *	  selected by the respective ITLBCFG or DTLBCFG special register,
+ *	  whose bits n*4+3 .. n*4 index the list of page sizes for way n
+ *	  (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n);
+ *	  this list may be sparse for auto-refill ways because auto-refill
+ *	  ways have independent lists of supported page sizes sharing a
+ *	  common encoding with PTE entries; the encoding is the index into
+ *	  this list; unsupported sizes for a given way are zero in the list;
+ *	  selecting unsupported sizes results in undefined hardware behaviour;
+ *	- is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition).

+ *  floop, floopnez, floopgtz, floopend
+ *
+ *  These macros are used for fast inner loops that
+ *  work whether or not the Loops options is configured.
+ *  If the Loops option is configured, they simply use
+ *  the zero-overhead LOOP instructions; otherwise
+ *  they use explicit decrement and branch instructions.
+ *
+ *  They are used in pairs, with floop, floopnez or floopgtz
+ *  at the beginning of the loop, and floopend at the end.
+ *
+ *  Each pair of loop macro calls must be given the loop count
+ *  address register and a unique label for that loop.
+ *
+ *  Example:
+ *
+ *	movi	 a3, 16     // loop 16 times
+ *	floop    a3, myloop1
+ *	:
+ *	bnez     a7, end1	// exit loop if a7 != 0
+ *	:
+ *	floopend a3, myloop1
+ *  end1:
+ *
+ *  Like the LOOP instructions, these macros cannot be
+ *  nested, must include at least one instruction,
+ *  cannot call functions inside the loop, etc.
+ *  The loop can be exited by jumping to the instruction
+ *  following floopend (or elsewhere outside the loop),
+ *  or continued by jumping to a NOP instruction placed
+ *  immediately before floopend.
+ *
+ *  Unlike LOOP instructions, the register passed to floop*
+ *  cannot be used inside the loop, because it is used as
+ *  the loop counter if the Loops option is not configured.
+ *  And its value is undefined after exiting the loop.
+ *  And because the loop counter register is active inside
+ *  the loop, you can't easily use this construct to loop
+ *  across a register file using ROTW as you might with LOOP
+ *  instructions, unless you copy the loop register along.

+ *	some_function:
+ *		entry	a1, 16

+ *
+ *		window_spill4	// spill windows of some_function's callers; preserves a0..a3 only;

+ *  the context of a simulation (as opposed to a Unix kernel).
+ *
+ *  These services behave largely as if they had been invoked
+ *  as a task in the simulator host's operating system
+ *  (eg. files accessed are those of the simulator host).
+ *  However, these SIMCALLs model a virtual operating system

+ *  of the host operating system used to run the simulation.
+ *  Rather these definitions are specific to the Xtensa ISS.
+ *  This way Xtensa ISA code written to use these SIMCALLs
+ *  can (in principle) be simulated on any host.
+ *
+ *  Up to 6 parameters are passed in registers a3 to a8
+ *  (note the 6th parameter isn't passed on the stack,
+ *   unlike windowed function calling conventions).
+ *  The return value is in a2.  A negative value in the

+ * in-memory bitmap:
+ *
+ * Use 16 bit block counters to track pending writes to each "chunk".
+ * The 2 high order bits are special-purpose, the first is a flag indicating
+ * whether a resync is needed.  The second is a flag indicating whether a
+ * resync is active.
+ * This means that the counter is actually 14 bits:
+ *
+ * +--------+--------+------------------------------------------------+
+ * | resync | resync |               counter                          |
+ * | needed | active |                                                |
+ * |  (0-1) |  (0-1) |              (0-16383)                         |
+ * +--------+--------+------------------------------------------------+
+ *
+ * The "resync needed" bit is set when:
+ *    a '1' bit is read from storage at startup.
+ *    a write request fails on some drives
+ *    a resync is aborted on a chunk with 'resync active' set
+ * It is cleared (and resync-active set) when a resync starts across all drives
+ * of the chunk.
+ *
+ *
+ * The "resync active" bit is set when:
+ *    a resync is started on all drives, and resync_needed is set.
+ *       resync_needed will be cleared (as long as resync_active wasn't already set).
+ * It is cleared when a resync completes.
+ *
+ * The counter counts pending write requests, plus the on-disk bit.
+ * When the counter is '1' and the resync bits are clear, the on-disk
+ * bit can be cleared aswell, thus setting the counter to 0.
+ * When we set a bit, or in the counter (to start a write), if the fields is
+ * 0, we first set the disk bit and set the counter to 1.
+ *
+ * If the counter is 0, the on-disk bit is clear and the stipe is clean
+ * Anything that dirties the stipe pushes the counter to 2 (at least)
+ * and sets the on-disk bit (lazily).
+ * If a periodic sweep find the counter at 2, it is decremented to 1.
+ * If the sweep find the counter at 1, the on-disk bit is cleared and the
+ * counter goes to zero.
+ *
+ * Also, we'll hijack the "map" pointer itself and use it as two 16 bit block
+ * counters as a fallback when "page" memory cannot be allocated:
+ *
+ * Normal case (page memory allocated):
+ *
+ *     page pointer (32-bit)
+ *
+ *     [ ] ------+
+ *               |
+ *               +-------> [   ][   ]..[   ] (4096 byte page == 2048 counters)
+ *                          c1   c2    c2048
+ *
+ * Hijacked case (page memory allocation failed):
+ *
+ *     hijacked page pointer (32-bit)
+ *
+ *     [		  ][		  ] (no page memory allocated)
+ *      counter #1 (16-bit) counter #2 (16-bit)

+ * mapping between physical and virtual addresses.  On processors
+ * where you can disable the MMU this is trivial, and easy.  For
+ * others it is still a simple predictable page table to setup.
+ *
+ * In that environment kexec copies the new kernel to its final
+ * resting place.  This means I can only support memory whose
+ * physical address can fit in an unsigned long.  In particular
+ * addresses where (pfn << PAGE_SHIFT) > ULONG_MAX cannot be handled.
+ * If the assembly stub has more restrictive requirements
+ * KEXEC_SOURCE_MEMORY_LIMIT and KEXEC_DEST_MEMORY_LIMIT can be
+ * defined more restrictively in <asm/kexec.h>.
+ *
+ * The code for the transition from the current kernel to the
+ * the new kernel is placed in the control_code_buffer, whose size
+ * is given by KEXEC_CONTROL_CODE_SIZE.  In the best case only a single
+ * page of memory is necessary, but some architectures require more.
+ * Because this memory must be identity mapped in the transition from
+ * virtual to physical addresses it must live in the range
+ * 0 - TASK_SIZE, as only the user space mappings are arbitrarily
+ * modifiable.
+ *
+ * The assembly stub in the control code buffer is passed a linked list
+ * of descriptor pages detailing the source pages of the new kernel,
+ * and the destination addresses of those source pages.  As this data
+ * structure is not used in the context of the current OS, it must
+ * be self-contained.
+ *
+ * The code has been made to work with highmem pages and will use a
+ * destination page in its final resting place (if it happens
+ * to allocate it).  The end product of this is that most of the
+ * physical address space, and most of RAM can be used.
+ *
+ * Future directions include:
+ *  - allocating a page table with the control code buffer identity

+ *	klist.c - Routines for manipulating klists.
+ *
+ *
+ *	This klist interface provides a couple of structures that wrap around 
+ *	struct list_head to provide explicit list "head" (struct klist) and 
+ *	list "node" (struct klist_node) objects. For struct klist, a spinlock
+ *	is included that protects access to the actual list itself. struct 
+ *	klist_node provides a pointer to the klist that owns it and a kref
+ *	reference count that indicates the number of current users of that node
+ *	in the list.
+ *
+ *	The entire point is to provide an interface for iterating over a list
+ *	that is safe and allows for modification of the list during the
+ *	iteration (e.g. insertion and removal), including modification of the
+ *	current node on the list.
+ *
+ *	It works using a 3rd object type - struct klist_iter - that is declared
+ *	and initialized before an iteration. klist_next() is used to acquire the
+ *	next element in the list. It returns NULL if there are no more items.
+ *	Internally, that routine takes the klist's lock, decrements the reference
+ *	count of the previous klist_node and increments the count of the next
+ *	klist_node. It then drops the lock and returns.
+ *
+ *	There are primitives for adding and removing nodes to/from a klist. 
+ *	When deleting, klist_del() will simply decrement the reference count. 
+ *	Only when the count goes to 0 is the node removed from the list. 
+ *	klist_remove() will try to delete the node from the list and block
+ *	until it is actually removed. This is useful for objects (like devices)
+ *	that have been removed from the system and must be freed (but must wait
+ *	until all accessors have finished).

+ * ==========================================================================
+ *
+ * INTRODUCTION
+ *
+ *   The textsearch infrastructure provides text searching facitilies for
+ *   both linear and non-linear data. Individual search algorithms are
+ *   implemented in modules and chosen by the user.
+ *
+ * ARCHITECTURE
+ *
+ *      User
+ *     +----------------+
+ *     |        finish()|<--------------(6)-----------------+
+ *     |get_next_block()|<--------------(5)---------------+ |
+ *     |                |                     Algorithm   | |
+ *     |                |                    +------------------------------+
+ *     |                |                    |  init()   find()   destroy() |
+ *     |                |                    +------------------------------+
+ *     |                |       Core API           ^       ^          ^
+ *     |                |      +---------------+  (2)     (4)        (8)
+ *     |             (1)|----->| prepare()     |---+       |          |
+ *     |             (3)|----->| find()/next() |-----------+          |
+ *     |             (7)|----->| destroy()     |----------------------+
+ *     +----------------+      +---------------+
+ *  
+ *   (1) User configures a search by calling _prepare() specifying the
+ *       search parameters such as the pattern and algorithm name.
+ *   (2) Core requests the algorithm to allocate and initialize a search
+ *       configuration according to the specified parameters.
+ *   (3) User starts the search(es) by calling _find() or _next() to
+ *       fetch subsequent occurrences. A state variable is provided
+ *       to the algorihtm to store persistant variables.
+ *   (4) Core eventually resets the search offset and forwards the find()
+ *       request to the algorithm.
+ *   (5) Algorithm calls get_next_block() provided by the user continously
+ *       to fetch the data to be searched in block by block.
+ *   (6) Algorithm invokes finish() after the last call to get_next_block
+ *       to clean up any leftovers from get_next_block. (Optional)
+ *   (7) User destroys the configuration by calling _destroy().
+ *   (8) Core notifies the algorithm to destroy algorithm specific
+ *       allocations. (Optional)
+ *
+ * USAGE
+ *
+ *   Before a search can be performed, a configuration must be created
+ *   by calling textsearch_prepare() specyfing the searching algorithm and
+ *   the pattern to look for. The returned configuration may then be used
+ *   for an arbitary amount of times and even in parallel as long as a
+ *   separate struct ts_state variable is provided to every instance.
+ *
+ *   The actual search is performed by either calling textsearch_find_-
+ *   continuous() for linear data or by providing an own get_next_block()
+ *   implementation and calling textsearch_find(). Both functions return
+ *   the position of the first occurrence of the patern or UINT_MAX if
+ *   no match was found. Subsequent occurences can be found by calling
+ *   textsearch_next() regardless of the linearity of the data.
+ *
+ *   Once you're done using a configuration it must be given back via
+ *   textsearch_destroy.
+ *
+ * EXAMPLE
+ *
+ *   int pos;
+ *   struct ts_config *conf;
+ *   struct ts_state state;
+ *   const char *pattern = "chicken";
+ *   const char *example = "We dance the funky chicken";
+ *
+ *   conf = textsearch_prepare("kmp", pattern, strlen(pattern),
+ *                             GFP_KERNEL, TS_AUTOLOAD);
+ *   if (IS_ERR(conf)) {
+ *       err = PTR_ERR(conf);
+ *       goto errout;
+ *   }
+ *
+ *   pos = textsearch_find_continuous(conf, &state, example, strlen(example));
+ *   if (pos != UINT_MAX)
+ *       panic("Oh my god, dancing chickens at %d\n", pos);
+ *
+ *   textsearch_destroy(conf);

+ * ==========================================================================
+ * 
+ *   Implements a linear-time string-matching algorithm due to Knuth,
+ *   Morris, and Pratt [1]. Their algorithm avoids the explicit
+ *   computation of the transition function DELTA altogether. Its
+ *   matching time is O(n), for n being length(text), using just an
+ *   auxiliary function PI[1..m], for m being length(pattern),
+ *   precomputed from the pattern in time O(m). The array PI allows
+ *   the transition function DELTA to be computed efficiently
+ *   "on the fly" as needed. Roughly speaking, for any state
+ *   "q" = 0,1,...,m and any character "a" in SIGMA, the value
+ *   PI["q"] contains the information that is independent of "a" and
+ *   is needed to compute DELTA("q", "a") [2]. Since the array PI
+ *   has only m entries, whereas DELTA has O(m|SIGMA|) entries, we
+ *   save a factor of |SIGMA| in the preprocessing time by computing
+ *   PI rather than DELTA.

+  To understand this stuff, an understanding of keys and all their bits is 
+  necessary. Every node in the trie has a key associated with it, but not 
+  all of the bits in that key are significant.
+
+  Consider a node 'n' and its parent 'tp'.
+
+  If n is a leaf, every bit in its key is significant. Its presence is 
+  necessitaded by path compression, since during a tree traversal (when 
+  searching for a leaf - unless we are doing an insertion) we will completely 
+  ignore all skipped bits we encounter. Thus we need to verify, at the end of 
+  a potentially successful search, that we have indeed been walking the 
+  correct key path.
+
+  Note that we can never "miss" the correct key in the tree if present by 
+  following the wrong path. Path compression ensures that segments of the key 
+  that are the same for all keys with a given prefix are skipped, but the 
+  skipped part *is* identical for each node in the subtrie below the skipped 
+  bit! trie_insert() in this implementation takes care of that - note the 
+  call to tkey_sub_equals() in trie_insert().
+
+  if n is an internal node - a 'tnode' here, the various parts of its key 
+  have many different meanings.
+
+  Example:  
+  _________________________________________________________________
+  | i | i | i | i | i | i | i | N | N | N | S | S | S | S | S | C |
+  -----------------------------------------------------------------
+    0   1   2   3   4   5   6   7   8   9  10  11  12  13  14  15

+
+  tp->pos = 7
+  tp->bits = 3
+  n->pos = 15

+
+  First, let's just ignore the bits that come before the parent tp, that is 
+  the bits from 0 to (tp->pos-1). They are *known* but at this point we do 
+  not use them for anything.
+
+  The bits from (tp->pos) to (tp->pos + tp->bits - 1) - "N", above - are the
+  index into the parent's child array. That is, they will be used to find 
+  'n' among tp's children.
+
+  The bits from (tp->pos + tp->bits) to (n->pos - 1) - "S" - are skipped bits
+  for the node n.
+
+  All the bits we have seen so far are significant to the node n. The rest 
+  of the bits are really not needed or indeed known in n->key.
+
+  The bits from (n->pos) to (n->pos + n->bits - 1) - "C" - are the index into

- *   o We do not change the loss detection or recovery mechanisms of
- *     Linux in any way. Linux already recovers from losses quite well,
- *     using fine-grained timers, NewReno, and FACK.
- *   o To avoid the performance penalty imposed by increasing cwnd
- *     only every-other RTT during slow start, we increase during
- *     every RTT during slow start, just like Reno.
- *   o Largely to allow continuous cwnd growth during slow start,
- *     we use the rate at which ACKs come back as the "actual"
- *     rate, rather than the rate at which data is sent.
- *   o To speed convergence to the right rate, we set the cwnd
- *     to achieve the right ("actual") rate when we exit slow start.
- *   o To filter out the noise caused by delayed ACKs, we use the
- *     minimum RTT sample observed during the last RTT to calculate
- *     the actual rate.
- *   o When the sender re-starts from idle, it waits until it has
- *     received ACKs for an entire flight of new data before making
- *     a cwnd adjustment decision. The original Vegas implementation
- *     assumed senders never went idle.

+ * TCP Vegas congestion control
+ *
+ * This is based on the congestion detection/avoidance scheme described in
+ *    Lawrence S. Brakmo and Larry L. Peterson.
+ *    "TCP Vegas: End to end congestion avoidance on a global internet."
+ *    IEEE Journal on Selected Areas in Communication, 13(8):1465--1480,
+ *    October 1995. Available from:
+ *	ftp://ftp.cs.arizona.edu/xkernel/Papers/jsac.ps
+ *
+ * See http://www.cs.arizona.edu/xkernel/ for their implementation.
+ * The main aspects that distinguish this implementation from the
+ * Arizona Vegas implementation are:
+ *   o We do not change the loss detection or recovery mechanisms of
+ *     Linux in any way. Linux already recovers from losses quite well,
+ *     using fine-grained timers, NewReno, and FACK.
+ *   o To avoid the performance penalty imposed by increasing cwnd
+ *     only every-other RTT during slow start, we increase during
+ *     every RTT during slow start, just like Reno.
+ *   o Largely to allow continuous cwnd growth during slow start,
+ *     we use the rate at which ACKs come back as the "actual"
+ *     rate, rather than the rate at which data is sent.
+ *   o To speed convergence to the right rate, we set the cwnd
+ *     to achieve the right ("actual") rate when we exit slow start.
+ *   o To filter out the noise caused by delayed ACKs, we use the
+ *     minimum RTT sample observed during the last RTT to calculate
+ *     the actual rate.
+ *   o When the sender re-starts from idle, it waits until it has
+ *     received ACKs for an entire flight of new data before making
+ *     a cwnd adjustment decision. The original Vegas implementation
+ *     assumed senders never went idle.

+ * If sd is an IPv4 socket, the addresses passed must be IPv4 addresses.
+ * If the sd is an IPv6 socket, the addresses passed can either be IPv4
+ * or IPv6 addresses.
+ *
+ * A single address may be specified as INADDR_ANY or IN6ADDR_ANY, see
+ * Section 3.1.2 for this usage.
+ *
+ * addrs is a pointer to an array of one or more socket addresses. Each
+ * address is contained in its appropriate structure (i.e. struct
+ * sockaddr_in or struct sockaddr_in6) the family of the address type
+ * must be used to distengish the address length (note that this
+ * representation is termed a "packed array" of addresses). The caller
+ * specifies the number of addresses in the array with addrcnt.
+ *
+ * On success, sctp_connectx() returns 0. On failure, sctp_connectx() returns
+ * -1, and sets errno to the appropriate error code.
+ *
+ * For SCTP, the port given in each socket address must be the same, or
+ * sctp_connectx() will fail, setting errno to EINVAL.
+ *
+ * An application can use sctp_connectx to initiate an association with
+ * an endpoint that is multi-homed.  Much like sctp_bindx() this call
+ * allows a caller to specify multiple addresses at which a peer can be
+ * reached.  The way the SCTP stack uses the list of addresses to set up
+ * the association is implementation dependant.  This function only
+ * specifies that the stack will try to make use of all the addresses in
+ * the list when needed.
+ *
+ * Note that the list of addresses passed in is only used for setting up
+ * the association.  It does not necessarily equal the set of addresses
+ * the peer uses for the resulting association.  If the caller wants to
+ * find out the set of peer addresses, it must use sctp_getpaddrs() to
+ * retrieve them after the association has been set up.
