+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+	why it is obsolete and when it can be expected to be removed.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.

 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.

+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(!)

+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
+-------

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

+Description
+-----------
+
+This driver implements support for the 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.

+Author: Charles Spirakis <bezaur@gmail.com>
+

+Credits:
+  w83781d.c:

+  Use 'init=1' to have the driver do extra software initializations.
+  The default behavior is to do the minimum initialization possible

+  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

+  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

+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 */
+};
+
+static struct platform_device myi2c = {
+	.name			= "ocores-i2c",
+	.dev = {
+		.platform_data	= &myi2c_data,
+	},
+	.num_resources		= ARRAY_SIZE(ocores_resources),

 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.
 
-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.
+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.  That's true even when your system is asleep!  The
+safest thing is to unmount all filesystems on removable media (such USB,
+Firewire, CompactFlash, MMC, external SATA, or even IDE hotplug bays)
+before suspending; then 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.

-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.

+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

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