This directory attempts to document the ABI between the Linux kernel and
userspace, and the relative stability of these interfaces. Due to the
everchanging nature of Linux, and the differing maturity levels, these
interfaces should be used by userspace programs in different ways.
We have four different levels of ABI stability, as shown by the four
different subdirectories in this location. Interfaces may change levels
of stability according to the rules described below.
The different levels of stability are:
stable/
This directory documents the interfaces that the developer has
defined to be stable. Userspace programs are free to use these
interfaces with no restrictions, and backward compatibility for
them will be guaranteed for at least 2 years. Most interfaces
(like syscalls) are expected to never change and always be
available.
testing/
This directory documents interfaces that are felt to be stable,
as the main development of this interface has been completed.
The interface can be changed to add new features, but the
current interface will not break by doing this, unless grave
errors or security problems are found in them. Userspace
programs can start to rely on these interfaces, but they must be
aware of changes that can occur before these interfaces move to
be marked stable. Programs that use these interfaces are
strongly encouraged to add their name to the description of
these interfaces, so that the kernel developers can easily
notify them if any changes occur (see the description of the
layout of the files below for details on how to do this.)
obsolete/
This directory documents interfaces that are still remaining in
the kernel, but are marked to be removed at some later point in
time. The description of the interface will document the reason
why it is obsolete and when it can be expected to be removed.
The file Documentation/feature-removal-schedule.txt may describe
some of these interfaces, giving a schedule for when they will
be removed.
removed/
This directory contains a list of the old interfaces that have
been removed from the kernel.
Every file in these directories will contain the following information:
What: Short description of the interface
Date: Date created
KernelVersion: Kernel version this feature first showed up in.
Contact: Primary contact for this interface (may be a mailing list)
Description: Long description of the interface and how to use it.
Users: All users of this interface who wish to be notified when
it changes. This is very important for interfaces in
the "testing" stage, so that kernel developers can work
with userspace developers to ensure that things do not
break in ways that are unacceptable. It is also
important to get feedback for these interfaces to make
sure they are working in a proper way and do not need to
be changed further.
How things move between levels:
Interfaces in stable may move to obsolete, as long as the proper
notification is given.
Interfaces may be removed from obsolete and the kernel as long as the
documented amount of time has gone by.
Interfaces in the testing state can move to the stable state when the
developers feel they are finished. They cannot be removed from the
kernel tree without going through the obsolete state first.
It's up to the developer to place their interfaces in the category they
wish for it to start out in.

Note that this interface is different for every architecture
that Linux supports. Please see the architecture-specific

Description:
The /sys/devices tree contains a snapshot of the
internal state of the kernel device tree. Devices will
be added and removed dynamically as the machine runs,
and between different kernel versions, the layout of the
devices within this tree will change.
Please do not rely on the format of this tree because of
this. If a program wishes to find different things in
the tree, please use the /sys/class structure and rely
on the symlinks there to point to the proper location
within the /sys/devices tree of the individual devices.
Or rely on the uevent messages to notify programs of
devices being added and removed from this tree to find
the location of those devices.
Note that sometimes not all devices along the directory
chain will have emitted uevent messages, so userspace
programs must be able to handle such occurrences.

See next chapter.
Chapter 5: Functions
Chapter 5: Typedefs
Please don't use things like "vps_t".
It's a _mistake_ to use typedef for structures and pointers. When you see a
vps_t a;
in the source, what does it mean?
In contrast, if it says
struct virtual_container *a;
you can actually tell what "a" is.
Lots of people think that typedefs "help readability". Not so. They are
useful only for:
(a) totally opaque objects (where the typedef is actively used to _hide_
what the object is).
Example: "pte_t" etc. opaque objects that you can only access using
the proper accessor functions.
NOTE! Opaqueness and "accessor functions" are not good in themselves.
The reason we have them for things like pte_t etc. is that there
really is absolutely _zero_ portably accessible information there.
(b) Clear integer types, where the abstraction _helps_ avoid confusion
whether it is "int" or "long".
u8/u16/u32 are perfectly fine typedefs, although they fit into
category (d) better than here.
NOTE! Again - there needs to be a _reason_ for this. If something is
"unsigned long", then there's no reason to do
typedef unsigned long myflags_t;
but if there is a clear reason for why it under certain circumstances
might be an "unsigned int" and under other configurations might be
"unsigned long", then by all means go ahead and use a typedef.
(c) when you use sparse to literally create a _new_ type for
type-checking.
(d) New types which are identical to standard C99 types, in certain
exceptional circumstances.
Although it would only take a short amount of time for the eyes and
brain to become accustomed to the standard types like 'uint32_t',
some people object to their use anyway.
Therefore, the Linux-specific 'u8/u16/u32/u64' types and their
signed equivalents which are identical to standard types are
permitted -- although they are not mandatory in new code of your
own.
When editing existing code which already uses one or the other set
of types, you should conform to the existing choices in that code.
(e) Types safe for use in userspace.
In certain structures which are visible to userspace, we cannot
require C99 types and cannot use the 'u32' form above. Thus, we
use __u32 and similar types in all structures which are shared
with userspace.
Maybe there are other cases too, but the rule should basically be to NEVER
EVER use a typedef unless you can clearly match one of those rules.
In general, a pointer, or a struct that has elements that can reasonably
be directly accessed should _never_ be a typedef.

Linux Kernel patch sumbittal checklist
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Here are some basic things that developers should do if they
want to see their kernel patch submittals accepted quicker.
These are all above and beyond the documentation that is provided
in Documentation/SubmittingPatches and elsewhere about submitting
Linux kernel patches.
- Builds cleanly with applicable or modified CONFIG options =y, =m, and =n.
No gcc warnings/errors, no linker warnings/errors.
- Passes allnoconfig, allmodconfig
- Builds on multiple CPU arch-es by using local cross-compile tools
or something like PLM at OSDL.
- ppc64 is a good architecture for cross-compilation checking because it
tends to use `unsigned long' for 64-bit quantities.
- Matches kernel coding style(!)
- Any new or modified CONFIG options don't muck up the config menu.
- All new Kconfig options have help text.
- Has been carefully reviewed with respect to relevant Kconfig
combinations. This is very hard to get right with testing --
brainpower pays off here.
- Check cleanly with sparse.
- Use 'make checkstack' and 'make namespacecheck' and fix any
problems that they find. Note: checkstack does not point out
problems explicitly, but any one function that uses more than
512 bytes on the stack is a candidate for change.
- Include kernel-doc to document global kernel APIs. (Not required
for static functions, but OK there also.) Use 'make htmldocs'
or 'make mandocs' to check the kernel-doc and fix any issues.
- Has been tested with CONFIG_PREEMPT, CONFIG_DEBUG_PREEMPT,
CONFIG_DEBUG_SLAB, CONFIG_DEBUG_PAGEALLOC, CONFIG_DEBUG_MUTEXES,
CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_SPINLOCK_SLEEP all simultaneously
enabled.
- Has been build- and runtime tested with and without CONFIG_SMP and
CONFIG_PREEMPT.
- If the patch affects IO/Disk, etc: has been tested with and without
CONFIG_LBD.

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

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

Byte 0:
This byte holds the reading from the sensor. Sensors in Bank1 can be both
volt and temp sensors, this is motherboard specific. The uGuru however does
seem to know (be programmed with) what kindoff sensor is attached see Sensor
Bank1 Settings description.
Volt sensors use a linear scale, a reading 0 corresponds with 0 volt and a
reading of 255 with 3494 mV. The sensors for higher voltages however are
connected through a division circuit. The currently known division circuits
in use result in ranges of: 0-4361mV, 0-6248mV or 0-14510mV. 3.3 volt sources
use the 0-4361mV range, 5 volt the 0-6248mV and 12 volt the 0-14510mV .
Temp sensors also use a linear scale, a reading of 0 corresponds with 0 degree
Celsius and a reading of 255 with a reading of 255 degrees Celsius.
Bank 0x22 Sensor Bank1 Settings (R)
Bank 0x23 Sensor Bank1 Settings (W)
-----------------------------------
This bank contains 16 sensors, for each sensor it contains 3 bytes. Each
set of 3 bytes contains the settings for the sensor with the same sensor
address in Bank 0x21 .

Temp sensor: Shutdown if temp is over the shutdown threshold (RW)
* This bit is only honored/used by the uGuru if a temp sensor is connected
** This bit is only honored/used by the uGuru if a volt sensor is connected
Note with some trickery this can be used to find out what kinda sensor is
detected see the Linux kernel driver for an example with many comments on
how todo this.

So far the following sensors are known to be available on all motherboards:
Sensor 0: CPU fan speed
Sensor 1: NB (or chipset for single chip) fan speed
Sensor 2: SYS fan speed
Byte 0:
This byte holds the reading from the sensor. 0-255 = 0-15300 (linear)
Bank 0x27 Sensors Bank2 Settings (R)
Bank 0x28 Sensors Bank2 Settings (W)
------------------------------------
This bank contains 6 sensors (AFAIK), for each sensor it contains 2 bytes.
Byte 0:
Alarm behaviour for the selected sensor. A 1 enables the described behaviour.
Bit 0: Give an alarm if measured rpm is under the min threshold (RW)
Bit 3: Beep if alarm (RW)
Bit 7: Shutdown if alarm persist for more then 4 seconds (RW)
Byte 1:
min threshold (scale as bank 0x26)
Warning for the adventerous
===========================
A word of caution to those who want to experiment and see if they can figure
the voltage / clock programming out, I tried reading and only reading banks
0-0x30 with the reading code used for the sensor banks (0x20-0x28) and this
resulted in a _permanent_ reprogramming of the voltages, luckily I had the
sensors part configured so that it would shutdown my system on any out of spec
voltages which proprably safed my computer (after a reboot I managed to
immediatly enter the bios and reload the defaults). This probably means that
the read/write cycle for the non sensor part is different from the sensor part.

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

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

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

Kernel driver w83791d
=====================
Supported chips:
* Winbond W83791D
Prefix: 'w83791d'
Addresses scanned: I2C 0x2c - 0x2f
Datasheet: http://www.winbond-usa.com/products/winbond_products/pdfs/PCIC/W83791Da.pdf
Author: Charles Spirakis <bezaur@gmail.com>

Module Parameters
-----------------
* init boolean
(default 0)
Use 'init=1' to have the driver do extra software initializations.
The default behavior is to do the minimum initialization possible
and depend on the BIOS to properly setup the chip. If you know you
have a w83791d and you're having problems, try init=1 before trying
reset=1.
* reset boolean
(default 0)
Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default
behavior is no chip reset to preserve BIOS settings.
* force_subclients=bus,caddr,saddr,saddr
This is used to force the i2c addresses for subclients of
a certain chip. Example usage is `force_subclients=0,0x2f,0x4a,0x4b'
to force the subclients of chip 0x2f on bus 0 to i2c addresses
0x4a and 0x4b.
Description
-----------
This driver implements support for the Winbond W83791D chip.
Detection of the chip can sometimes be foiled because it can be in an
internal state that allows no clean access (Bank with ID register is not
currently selected). If you know the address of the chip, use a 'force'
parameter; this will put it into a more well-behaved state first.
The driver implements three temperature sensors, five fan rotation speed
sensors, and ten voltage sensors.
Temperatures are measured in degrees Celsius and measurement resolution is 1
degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
the temperature gets higher than the Overtemperature Shutdown value; it stays
on until the temperature falls below the Hysteresis value.
Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
triggered if the rotation speed has dropped below a programmable limit. Fan
readings can be divided by a programmable divider (1, 2, 4, 8 for fan 1/2/3
and 1, 2, 4, 8, 16, 32, 64 or 128 for fan 4/5) to give the readings more
range or accuracy.
Voltage sensors (also known as IN sensors) report their values in millivolts.
An alarm is triggered if the voltage has crossed a programmable minimum
or maximum limit.
Alarms are provided as output from a "realtime status register". The
following bits are defined:
bit - alarm on:
0 - Vcore
1 - VINR0
2 - +3.3VIN
3 - 5VDD
4 - temp1
5 - temp2
6 - fan1
7 - fan2
8 - +12VIN
9 - -12VIN
10 - -5VIN
11 - fan3
12 - chassis

16 - tart1
17 - tart2
18 - tart3
19 - VSB
20 - VBAT
21 - fan4
22 - fan5
23 - reserved
When an alarm goes off, you can be warned by a beeping signal through your
computer speaker. It is possible to enable all beeping globally, or only
the beeping for some alarms.
The driver only reads the chip values each 3 seconds; reading them more
often will do no harm, but will return 'old' values.

Description
-----------
i2c-ocores is an i2c bus driver for the OpenCores.org I2C controller
IP core by Richard Herveille.
Usage
-----
i2c-ocores uses the platform bus, so you need to provide a struct
platform_device with the base address and interrupt number. The
dev.platform_data of the device should also point to a struct
ocores_i2c_platform_data (see linux/i2c-ocores.h) describing the
distance between registers and the input clock speed.
E.G. something like:
static struct resource ocores_resources[] = {
[0] = {
.start = MYI2C_BASEADDR,
.end = MYI2C_BASEADDR + 8,
.flags = IORESOURCE_MEM,
},
[1] = {
.start = MYI2C_IRQ,
.end = MYI2C_IRQ,
.flags = IORESOURCE_IRQ,
},
};
static struct ocores_i2c_platform_data myi2c_data = {
.regstep = 2, /* two bytes between registers */
.clock_khz = 50000, /* input clock of 50MHz */
};

.name = "ocores-i2c",
.dev = {
.platform_data = &myi2c_data,

If you own Force CPCI735 motherboard or other OSB4 based systems you may need
to change the SMBus Interrupt Select register so the SMBus controller uses
the SMI mode.
1) Use lspci command and locate the PCI device with the SMBus controller:
00:0f.0 ISA bridge: ServerWorks OSB4 South Bridge (rev 4f)
The line may vary for different chipsets. Please consult the driver source
for all possible PCI ids (and lspci -n to match them). Lets assume the
device is located at 00:0f.0.
2) Now you just need to change the value in 0xD2 register. Get it first with
command: lspci -xxx -s 00:0f.0
If the value is 0x3 then you need to change it to 0x1
setpci -s 00:0f.0 d2.b=1
Please note that you don't need to do that in all cases, just when the SMBus is
not working properly.
Hardware-specific issues
------------------------
This driver will refuse to load on IBM systems with an Intel PIIX4 SMBus.
Some of these machines have an RFID EEPROM (24RF08) connected to the SMBus,
which can easily get corrupted due to a state machine bug. These are mostly
Thinkpad laptops, but desktop systems may also be affected. We have no list
of all affected systems, so the only safe solution was to prevent access to
the SMBus on all IBM systems (detected using DMI data.)

MEMORY ATTRIBUTE ALIASING ON IA-64
Bjorn Helgaas
<bjorn.helgaas@hp.com>
May 4, 2006
MEMORY ATTRIBUTES
Itanium supports several attributes for virtual memory references.
The attribute is part of the virtual translation, i.e., it is
contained in the TLB entry. The ones of most interest to the Linux
kernel are:
WB Write-back (cacheable)
UC Uncacheable
WC Write-coalescing
System memory typically uses the WB attribute. The UC attribute is
used for memory-mapped I/O devices. The WC attribute is uncacheable
like UC is, but writes may be delayed and combined to increase
performance for things like frame buffers.
The Itanium architecture requires that we avoid accessing the same
page with both a cacheable mapping and an uncacheable mapping[1].
The design of the chipset determines which attributes are supported
on which regions of the address space. For example, some chipsets
support either WB or UC access to main memory, while others support
only WB access.
MEMORY MAP
Platform firmware describes the physical memory map and the
supported attributes for each region. At boot-time, the kernel uses
the EFI GetMemoryMap() interface. ACPI can also describe memory
devices and the attributes they support, but Linux/ia64 currently
doesn't use this information.
The kernel uses the efi_memmap table returned from GetMemoryMap() to
learn the attributes supported by each region of physical address
space. Unfortunately, this table does not completely describe the
address space because some machines omit some or all of the MMIO
regions from the map.
The kernel maintains another table, kern_memmap, which describes the
memory Linux is actually using and the attribute for each region.
This contains only system memory; it does not contain MMIO space.
The kern_memmap table typically contains only a subset of the system
memory described by the efi_memmap. Linux/ia64 can't use all memory
in the system because of constraints imposed by the identity mapping
scheme.
The efi_memmap table is preserved unmodified because the original
boot-time information is required for kexec.
KERNEL IDENTITY MAPPINGS
Linux/ia64 identity mappings are done with large pages, currently
either 16MB or 64MB, referred to as "granules." Cacheable mappings
are speculative[2], so the processor can read any location in the
page at any time, independent of the programmer's intentions. This
means that to avoid attribute aliasing, Linux can create a cacheable
identity mapping only when the entire granule supports cacheable
access.
Therefore, kern_memmap contains only full granule-sized regions that
can referenced safely by an identity mapping.
Uncacheable mappings are not speculative, so the processor will
generate UC accesses only to locations explicitly referenced by
software. This allows UC identity mappings to cover granules that
are only partially populated, or populated with a combination of UC
and WB regions.
USER MAPPINGS
User mappings are typically done with 16K or 64K pages. The smaller
page size allows more flexibility because only 16K or 64K has to be
homogeneous with respect to memory attributes.
POTENTIAL ATTRIBUTE ALIASING CASES
There are several ways the kernel creates new mappings:
mmap of /dev/mem
This uses remap_pfn_range(), which creates user mappings. These
mappings may be either WB or UC. If the region being mapped
happens to be in kern_memmap, meaning that it may also be mapped
by a kernel identity mapping, the user mapping must use the same
attribute as the kernel mapping.
If the region is not in kern_memmap, the user mapping should use
an attribute reported as being supported in the EFI memory map.
Since the EFI memory map does not describe MMIO on some
machines, this should use an uncacheable mapping as a fallback.
mmap of /sys/class/pci_bus/.../legacy_mem
This is very similar to mmap of /dev/mem, except that legacy_mem
only allows mmap of the one megabyte "legacy MMIO" area for a
specific PCI bus. Typically this is the first megabyte of
physical address space, but it may be different on machines with
several VGA devices.
"X" uses this to access VGA frame buffers. Using legacy_mem
rather than /dev/mem allows multiple instances of X to talk to
different VGA cards.
The /dev/mem mmap constraints apply.
However, since this is for mapping legacy MMIO space, WB access
does not make sense. This matters on machines without legacy
VGA support: these machines may have WB memory for the entire
first megabyte (or even the entire first granule).
On these machines, we could mmap legacy_mem as WB, which would
be safe in terms of attribute aliasing, but X has no way of
knowing that it is accessing regular memory, not a frame buffer,
so the kernel should fail the mmap rather than doing it with WB.
read/write of /dev/mem
This uses copy_from_user(), which implicitly uses a kernel
identity mapping. This is obviously safe for things in
kern_memmap.
There may be corner cases of things that are not in kern_memmap,
but could be accessed this way. For example, registers in MMIO
space are not in kern_memmap, but could be accessed with a UC
mapping. This would not cause attribute aliasing. But
registers typically can be accessed only with four-byte or
eight-byte accesses, and the copy_from_user() path doesn't allow
any control over the access size, so this would be dangerous.
ioremap()
This returns a kernel identity mapping for use inside the
kernel.
If the region is in kern_memmap, we should use the attribute
specified there. Otherwise, if the EFI memory map reports that
the entire granule supports WB, we should use that (granules
that are partially reserved or occupied by firmware do not appear
in kern_memmap). Otherwise, we should use a UC mapping.
PAST PROBLEM CASES
mmap of various MMIO regions from /dev/mem by "X" on Intel platforms
The EFI memory map may not report these MMIO regions.
These must be allowed so that X will work. This means that
when the EFI memory map is incomplete, every /dev/mem mmap must
succeed. It may create either WB or UC user mappings, depending
on whether the region is in kern_memmap or the EFI memory map.
mmap of 0x0-0xA0000 /dev/mem by "hwinfo" on HP sx1000 with VGA enabled
See https://bugzilla.novell.com/show_bug.cgi?id=140858.
The EFI memory map reports the following attributes:
0x00000-0x9FFFF WB only
0xA0000-0xBFFFF UC only (VGA frame buffer)
0xC0000-0xFFFFF WB only
This mmap is done with user pages, not kernel identity mappings,
so it is safe to use WB mappings.
The kernel VGA driver may ioremap the VGA frame buffer at 0xA0000,
which will use a granule-sized UC mapping covering 0-0xFFFFF. This
granule covers some WB-only memory, but since UC is non-speculative,
the processor will never generate an uncacheable reference to the
WB-only areas unless the driver explicitly touches them.
mmap of 0x0-0xFFFFF legacy_mem by "X"
If the EFI memory map reports this entire range as WB, there
is no VGA MMIO hole, and the mmap should fail or be done with
a WB mapping.
There's no easy way for X to determine whether the 0xA0000-0xBFFFF
region is a frame buffer or just memory, so I think it's best to
just fail this mmap request rather than using a WB mapping. As
far as I know, there's no need to map legacy_mem with WB
mappings.
Otherwise, a UC mapping of the entire region is probably safe.
The VGA hole means the region will not be in kern_memmap. The
HP sx1000 chipset doesn't support UC access to the memory surrounding
the VGA hole, but X doesn't need that area anyway and should not
reference it.
mmap of 0xA0000-0xBFFFF legacy_mem by "X" on HP sx1000 with VGA disabled
The EFI memory map reports the following attributes:
0x00000-0xFFFFF WB only (no VGA MMIO hole)
This is a special case of the previous case, and the mmap should
fail for the same reason as above.

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

bogus network interfaces to trick firewalls or administrators.

You still need to call request_region() for I/O regions and
request_mem_region() for memory regions to make sure nobody else is using the
same device.
The device driver needs to call pci_request_region() to make sure
no other device is already using the same resource. The driver is expected
to determine MMIO and IO Port resource availability _before_ calling
pci_enable_device(). Conversely, drivers should call pci_release_region()
_after_ calling pci_disable_device(). The idea is to prevent two devices
colliding on the same address range.
Generic flavors of pci_request_region() are request_mem_region()
(for MMIO ranges) and request_region() (for IO Port ranges).
Use these for address resources that are not described by "normal" PCI
interfaces (e.g. BAR).
All interrupt handlers should be registered with SA_SHIRQ and use the devid
to map IRQs to devices (remember that all PCI interrupts are shared).

there are flags.

actual policy of what to do with them beeing specific to a given
driver. It's acceptable for a network driver to just drop packets
while a block driver is expected to block the queue so no request is
lost. (Use IDE as an example on how to do that). FREEZE requires no
power state change, and it's expected for drivers to be able to
quickly transition back to operating state.
SUSPEND -- like FREEZE, but also put hardware into low-power state. If
there's need to distinguish several levels of sleep, additional flag

Q: Is this true that if I have a mounted filesystem on a USB device and
I suspend to disk, I can lose data unless the filesystem has been mounted
with "sync"?
A: That's right. It depends on your hardware, and it could be true even for
suspend-to-RAM. In fact, even with "-o sync" you can lose data if your
programs have information in buffers they haven't written out to disk.
A: That's right ... if you disconnect that device, you may lose data.
In fact, even with "-o sync" you can lose data if your programs have
information in buffers they haven't written out to a disk you disconnect,
or if you disconnect before the device finished saving data you wrote.
If you're lucky, your hardware will support low-power modes for USB
controllers while the system is asleep. Lots of hardware doesn't,
however. Shutting off the power to a USB controller is equivalent to
unplugging all the attached devices.
Software suspend normally powers down USB controllers, which is equivalent
to disconnecting all USB devices attached to your system.
Your system might well support low-power modes for its USB controllers
while the system is asleep, maintaining the connection, using true sleep
modes like "suspend-to-RAM" or "standby". (Don't write "disk" to the
/sys/power/state file; write "standby" or "mem".) We've not seen any
hardware that can use these modes through software suspend, although in
theory some systems might support "platform" or "firmware" modes that
won't break the USB connections.
Remember that it's always a bad idea to unplug a disk drive containing a
mounted filesystem. With USB that's true even when your system is asleep!
The safest thing is to unmount all USB-based filesystems before suspending
and remount them after resuming.

Q: I upgraded the kernel from 2.6.15 to 2.6.16. Both kernels were
compiled with the similar configuration files. Anyway I found that
suspend to disk (and resume) is much slower on 2.6.16 compared to
2.6.15. Any idea for why that might happen or how can I speed it up?
A: This is because the size of the suspend image is now greater than
for 2.6.15 (by saving more data we can get more responsive system
after resume).
There's the /sys/power/image_size knob that controls the size of the
image. If you set it to 0 (eg. by echo 0 > /sys/power/image_size as
root), the 2.6.15 behavior should be restored. If it is still too
slow, take a look at suspend.sf.net -- userland suspend is faster and
supports LZF compression to speed it up further.

Notes for CPQFCTS driver for Compaq Tachyon TS
Fibre Channel Host Bus Adapter, PCI 64-bit, 66MHz
for Linux (RH 6.1, 6.2 kernel 2.2.12-32, 2.2.14-5)
SMP tested
Tested in single and dual HBA configuration, 32 and 64bit busses,
33 and 66MHz. Only supports FC-AL.
SEST size 512 Exchanges (simultaneous I/Os) limited by module kmalloc()
max of 128k bytes contiguous.
Ver 2.5.4 Oct 03, 2002
* fixed memcpy of sense buffer in ioctl to copy the smaller defined size
Ver 2.5.3 Aug 01, 2002
* fix the passthru ioctl to handle the Scsi_Cmnd->request being a pointer
Ver 2.5.1 Jul 30, 2002
* fix ioctl to pay attention to the specified LUN.
Ver 2.5.0 Nov 29, 2001
* eliminated io_request_lock. This change makes the driver specific
to the 2.5.x kernels.
* silenced excessively noisy printks.
Ver 2.1.2 July 23, 2002
* initialize DumCmnd->lun in cpqfcTS_ioctl (used in fcFindLoggedInPorts as LUN index)
Ver 2.1.1 Oct 18, 2001
* reinitialize Cmnd->SCp.sent_command (used to identify commands as
passthrus) on calling scsi_done, since the scsi mid layer does not
use (or reinitialize) this field to prevent subsequent comands from
having it set incorrectly.
Ver 2.1.0 Aug 27, 2001
* Revise driver to use new kernel 2.4.x PCI DMA API, instead of
virt_to_bus(). (enables driver to work w/ ia64 systems with >2Gb RAM.)
Rework main scatter-gather code to handle cases where SG element
lengths are larger than 0x7FFFF bytes and use as many scatter
gather pages as necessary. (Steve Cameron)
* Makefile changes to bring cpqfc into line w/ rest of SCSI drivers
(thanks to Keith Owens)
Ver 2.0.5 Aug 06, 2001
* Reject non-existent luns in the driver rather than letting the
hardware do it. (some HW behaves differently than others in this area.)
* Changed Makefile to rely on "make dep" instead of explicit dependencies
* ifdef'ed out fibre channel analyzer triggering debug code
* fixed a jiffies wrapping issue
Ver 2.0.4 Aug 01, 2001
* Incorporated fix for target device reset from Steeleye
* Fixed passthrough ioctl so it doesn't hang.
* Fixed hang in launch_FCworker_thread() that occurred on some machines.
* Avoid problem when number of volumes in a single cabinet > 8
Ver 2.0.2 July 23, 2001
Changed the semiphore changes so the driver would compile in 2.4.7.
This version is for 2.4.7 and beyond.
Ver 2.0.1 May 7, 2001
Merged version 1.3.6 fixes into version 2.0.0.
Ver 2.0.0 May 7, 2001
Fixed problem so spinlock is being initialized to UNLOCKED.
Fixed updated driver so it compiles in the 2.4 tree.
Ver 1.3.6 Feb 27, 2001
Added Target_Device_Reset function for SCSI error handling
Fixed problem with not reseting addressing mode after implicit logout
Ver 1.3.4 Sep 7, 2000
Added Modinfo information
Fixed problem with statically linking the driver
Ver 1.3.3, Aug 23, 2000
Fixed device/function number in ioctl
Ver 1.3.2, July 27, 2000
Add include for Alpha compile on 2.2.14 kernel (cpq*i2c.c)
Change logic for different FCP-RSP sense_buffer location for HSG80 target
And search for Agilent Tachyon XL2 HBAs (not finished! - in test)

*************************
If a GBIC of type Short-wave, Long-wave, or Copper is detected, it will
print out; otherwise, "none" is displayed. If the cabling is correct
and a loop circuit is completed, you should see "Monitor"; otherwise,
"LoopFail" (on open circuit) or some LPSM number/state with bit 3 set.
ERRATA:
1. Normally, Linux Scsi queries FC devices with INQUIRY strings. All LUNs
found according to INQUIRY should get READ commands at sector 0 to find
partition table, etc. Older kernels only query the first 4 devices. Some
Linux kernels only look for one LUN per target (i.e. FC device).
2. Physically removing a device, or a malfunctioning system which hides a
device, leads to a 30-second timeout and subsequent _abort call.
In some process contexts, this will hang the kernel (crashing the system).
Single bit errors in frames and virtually all hot plugging events are
gracefully handled with internal driver timer and Abort processing.
3. Some SCSI drives with error conditions will not handle the 7 second timeout
in this software driver, leading to infinite retries on timed out SCSI commands.
The 7 secs balances the need to quickly recover from lost frames (esp. on sequence
initiatives) and time needed by older/slower/error-state drives in responding.
This can be easily changed in "Exchanges[].timeOut".
4. Due to the nature of FC soft addressing, there is no assurance that the
same LUNs (drives) will have the same path (e.g. /dev/sdb1) from one boot to
next. Dynamic soft address changes (i.e. 24-bit FC port_id) are
supported during run time (e.g. due to hot plug event) by the use of WWN to
SCSI Nexus (channel/target/LUN) mapping.
5. Compaq RA4x00 firmware version 2.54 and later supports SSP (Selective
Storage Presentation), which maps LUNs to a WWN. If RA4x00 firmware prior
2.54 (e.g. older controller) is used, or the FC HBA is replaced (another WWN
is used), logical volumes on the RA4x00 will no longer be visible.

HIGHPOINT ROCKETRAID 3xxx RAID DRIVER (hptiop)
Controller Register Map
-------------------------
The controller IOP is accessed via PCI BAR0.
BAR0 offset Register
0x10 Inbound Message Register 0
0x14 Inbound Message Register 1
0x18 Outbound Message Register 0
0x1C Outbound Message Register 1
0x20 Inbound Doorbell Register
0x24 Inbound Interrupt Status Register
0x28 Inbound Interrupt Mask Register
0x30 Outbound Interrupt Status Register
0x34 Outbound Interrupt Mask Register
0x40 Inbound Queue Port
0x44 Outbound Queue Port
I/O Request Workflow
----------------------
All queued requests are handled via inbound/outbound queue port.
A request packet can be allocated in either IOP or host memory.
To send a request to the controller:
- Get a free request packet by reading the inbound queue port or
allocate a free request in host DMA coherent memory.
The value returned from the inbound queue port is an offset
relative to the IOP BAR0.
Requests allocated in host memory must be aligned on 32-bytes boundary.
- Fill the packet.
- Post the packet to IOP by writing it to inbound queue. For requests
allocated in IOP memory, write the offset to inbound queue port. For
requests allocated in host memory, write (0x80000000|(bus_addr>>5))
to the inbound queue port.
- The IOP process the request. When the request is completed, it
will be put into outbound queue. An outbound interrupt will be
generated.
For requests allocated in IOP memory, the request offset is posted to
outbound queue.
For requests allocated in host memory, (0x80000000|(bus_addr>>5))
is posted to the outbound queue. If IOP_REQUEST_FLAG_OUTPUT_CONTEXT
flag is set in the request, the low 32-bit context value will be
posted instead.
- The host read the outbound queue and complete the request.
For requests allocated in IOP memory, the host driver free the request
by writing it to the outbound queue.
Non-queued requests (reset/flush etc) can be sent via inbound message
register 0. An outbound message with the same value indicates the completion
of an inbound message.
User-level Interface
---------------------
The driver exposes following sysfs attributes:
NAME R/W Description
driver-version R driver version string
firmware-version R firmware version string
The driver registers char device "hptiop" to communicate with HighPoint RAID
management software. Its ioctl routine acts as a general binary interface
between the IOP firmware and HighPoint RAID management software. New management
functions can be implemented in application/firmware without modification
in driver code.

error occurs, the field contains the error code. In case of a submission of
a Control packet, this field contains a Setup Tag instead of an error code.
It is easy to tell whether the Setup Tag is present because it is never a
number. Thus if scripts find a number in this field, they proceed to read
Data Length. If they find something else, like a letter, they read the setup
packet before reading the Data Length.
- Setup packet, if present, consists of 5 words: one of each for bmRequestType,

These words are safe to decode if Setup Tag was 's'. Otherwise, the setup
packet was present, but not captured, and the fields contain filler.

The data words are present only if this tag is '='.
- Data words follow, in big endian hexadecimal format. Notice that they are
not machine words, but really just a byte stream split into words to make

TODO list
---------
- Page migration requires the use of swap handles to preserve the
information of the anonymous page table entries. This means that swap
space is reserved but never used. The maximum number of swap handles used
is determined by CHUNK_SIZE (see mm/mempolicy.c) per ongoing migration.
Reservation of pages could be avoided by having a special type of swap
handle that does not require swap space and that would only track the page
references. Something like that was proposed by Marcelo Tosatti in the
past (search for migration cache on lkml or linux-mm@kvack.org).
- Page migration unmaps ptes for file backed pages and requires page
faults to reestablish these ptes. This could be optimized by somehow
recording the references before migration and then reestablish them later.
However, there are several locking challenges that have to be overcome
before this is possible.
- Page migration generates read ptes for anonymous pages. Dirty page
faults are required to make the pages writable again. It may be possible
to generate a pte marked dirty if it is known that the page is dirty and
that this process has the only reference to that page.

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.
If there is no driver for the family, default one is assigned, which allows to perform
almost any kind of operations. Each logical operation is a transaction
in nature, which can contain several (two or one) low-level operations.
Let's see how one can read EEPROM context:
1. one must write control buffer, i.e. buffer containing command byte
and two byte address. At this step bus is reset and appropriate device
is selected using either W1_SKIP_ROM or W1_MATCH_ROM command.
Then provided control buffer is being written to the wire.
2. reading. This will issue reading eeprom response.
It is possible that between 1. and 2. w1 master thread will reset bus for searching
and slave device will be even removed, but in this case 0xff will

Userspace communication protocol over connector [1].
Message types.
=============
There are three types of messages between w1 core and userspace:
1. Events. They are generated each time new master or slave device found
either due to automatic or requested search.
2. Userspace commands. Includes read/write and search/alarm search comamnds.
3. Replies to userspace commands.
Protocol.
========
[struct cn_msg] - connector header. It's length field is equal to size of the attached data.
[struct w1_netlink_msg] - w1 netlink header.
__u8 type - message type.
W1_SLAVE_ADD/W1_SLAVE_REMOVE - slave add/remove events.
W1_MASTER_ADD/W1_MASTER_REMOVE - master add/remove events.
W1_MASTER_CMD - userspace command for bus master device (search/alarm search).
W1_SLAVE_CMD - userspace command for slave device (read/write/ search/alarm search
for bus master device where given slave device found).
__u8 res - reserved
__u16 len - size of attached to this header data.
union {
__u8 id; - slave unique device id
struct w1_mst {
__u32 id; - master's id.
__u32 res; - reserved
} mst;
} id;
[strucrt w1_netlink_cmd] - command for gived master or slave device.
__u8 cmd - command opcode.
W1_CMD_READ - read command.
W1_CMD_WRITE - write command.
W1_CMD_SEARCH - search command.
W1_CMD_ALARM_SEARCH - alarm search command.
__u8 res - reserved
__u16 len - length of data for this command.
For read command data must be allocated like for write command.
__u8 data[0] - data for this command.
Each connector message can include one or more w1_netlink_msg with zero of more attached w1_netlink_cmd messages.
For event messages there are no w1_netlink_cmd embedded structures, only connector header
and w1_netlink_msg strucutre with "len" field being zero and filled type (one of event types)
and id - either 8 bytes of slave unique id in host order, or master's id, which is assigned
to bus master device when it is added to w1 core.
Currently replies to userspace commands are only generated for read command request.
One reply is generated exactly for one w1_netlink_cmd read request.
Replies are not combined when sent - i.e. typical reply messages looks like the following:
[cn_msg][w1_netlink_msg][w1_netlink_cmd]
cn_msg.len = sizeof(struct w1_netlink_msg) + sizeof(struct w1_netlink_cmd) + cmd->len;
w1_netlink_msg.len = sizeof(struct w1_netlink_cmd) + cmd->len;
w1_netlink_cmd.len = cmd->len;
Operation steps in w1 core when new command is received.
=======================================================
When new message (w1_netlink_msg) is received w1 core detects if it is master of slave request,
according to w1_netlink_msg.type field.
Then master or slave device is searched for.
When found, master device (requested or those one on where slave device is found) is locked.
If slave command is requested, then reset/select procedure is started to select given device.
Then all requested in w1_netlink_msg operations are performed one by one.
If command requires reply (like read command) it is sent on command completion.
When all commands (w1_netlink_cmd) are processed muster device is unlocked
and next w1_netlink_msg header processing started.
Connector [1] specific documentation.
====================================
Each connector message includes two u32 fields as "address".
w1 uses CN_W1_IDX and CN_W1_VAL defined in include/linux/connector.h header.
Each message also includes sequence and acknowledge numbers.
Sequence number for event messages is appropriate bus master sequence number increased with
each event message sent "through" this master.
Sequence number for userspace requests is set by userspace application.
Sequence number for reply is the same as was in request, and
acknowledge number is set to seq+1.
Additional documantion, source code examples.
============================================
1. Documentation/connector
2. http://tservice.net.ru/~s0mbre/archive/w1
This archive includes userspace application w1d.c which
uses read/write/search commands for all master/slave devices found on the bus.
