 Contact:	Greg Kroah-Hartman <gregkh@suse.de>
 Description:
 	devfs has been unmaintained for a number of years, has unfixable
 	races, contains a naming policy within the kernel that is
 	against the LSB, and can be replaced by using udev.
-	The files fs/devfs/*, include/linux/devfs_fs*.h will be removed,

+Description:
+		The /sys/power/state file controls the system power state.
+		Reading from this file returns what states are supported,
+		which is hard-coded to 'standby' (Power-On Suspend), 'mem'
+		(Suspend-to-RAM), and 'disk' (Suspend-to-Disk).
+
+		Writing to this file one of these strings causes the system to
+		transition into that state. Please see the file
+		Documentation/power/states.txt for a description of each of
+		these states.

+Contact:	Rafael J. Wysocki <rjw@sisk.pl>
+Description:
+		The /sys/power/disk file controls the operating mode of the
+		suspend-to-disk mechanism.  Reading from this file returns
+		the name of the method by which the system will be put to
+		sleep on the next suspend.  There are four methods supported:
+		'firmware' - means that the memory image will be saved to disk
+		by some firmware, in which case we also assume that the
+		firmware will handle the system suspend.
+		'platform' - the memory image will be saved by the kernel and
+		the system will be put to sleep by the platform driver (e.g.
+		ACPI or other PM registers).
+		'shutdown' - the memory image will be saved by the kernel and
+		the system will be powered off.
+		'reboot' - the memory image will be saved by the kernel and
+		the system will be rebooted.
+
+		The suspend-to-disk method may be chosen by writing to this
+		file one of the accepted strings:
+
+		'firmware'
+		'platform'
+		'shutdown'
+		'reboot'
+
+		It will only change to 'firmware' or 'platform' if the system
+		supports that.

+Description:
+		The /sys/power/image_size file controls the size of the image
+		created by the suspend-to-disk mechanism.  It can be written a
+		string representing a non-negative integer that will be used
+		as an upper limit of the image size, in bytes.  The kernel's
+		suspend-to-disk code will do its best to ensure the image size
+		will not exceed this number.  However, if it turns out to be
+		impossible, the kernel will try to suspend anyway using the
+		smallest image possible.  In particular, if "0" is written to
+		this file, the suspend image will be as small as possible.
+
+		Reading from this file will display the current image size
+		limit, which is set to 500 MB by default.

+What:		/sys/power/pm_trace
+Date:		August 2006
+Contact:	Rafael J. Wysocki <rjw@sisk.pl>
+Description:
+		The /sys/power/pm_trace file controls the code which saves the
+		last PM event point in the RTC across reboots, so that you can
+		debug a machine that just hangs during suspend (or more
+		commonly, during resume).  Namely, the RTC is only used to save
+		the last PM event point if this file contains '1'.  Initially
+		it contains '0' which may be changed to '1' by writing a
+		string representing a nonzero integer into it.
+
+		To use this debugging feature you should attempt to suspend
+		the machine, then reboot it and run
+
+		dmesg -s 1000000 | grep 'hash matches'
+
+		CAUTION: Using it will cause your machine's real-time (CMOS)
+		clock to be set to a random invalid time after a resume.

+		Chapter 16: Function return values and names
+
+Functions can return values of many different kinds, and one of the
+most common is a value indicating whether the function succeeded or
+failed.  Such a value can be represented as an error-code integer
+(-Exxx = failure, 0 = success) or a "succeeded" boolean (0 = failure,
+non-zero = success).
+
+Mixing up these two sorts of representations is a fertile source of
+difficult-to-find bugs.  If the C language included a strong distinction
+between integers and booleans then the compiler would find these mistakes
+for us... but it doesn't.  To help prevent such bugs, always follow this
+convention:
+
+	If the name of a function is an action or an imperative command,
+	the function should return an error-code integer.  If the name
+	is a predicate, the function should return a "succeeded" boolean.
+
+For example, "add work" is a command, and the add_work() function returns 0
+for success or -EBUSY for failure.  In the same way, "PCI device present" is
+a predicate, and the pci_dev_present() function returns 1 if it succeeds in
+finding a matching device or 0 if it doesn't.
+
+All EXPORTed functions must respect this convention, and so should all
+public functions.  Private (static) functions need not, but it is
+recommended that they do.
+
+Functions whose return value is the actual result of a computation, rather
+than an indication of whether the computation succeeded, are not subject to
+this rule.  Generally they indicate failure by returning some out-of-range
+result.  Typical examples would be functions that return pointers; they use
+NULL or the ERR_PTR mechanism to report failure.

+The struct taskstats
+--------------------
+
+This document contains an explanation of the struct taskstats fields.
+
+There are three different groups of fields in the struct taskstats:
+
+1) Common and basic accounting fields
+    If CONFIG_TASKSTATS is set, the taskstats inteface is enabled and
+    the common fields and basic accounting fields are collected for
+    delivery at do_exit() of a task.
+2) Delay accounting fields
+    These fields are placed between
+    /* Delay accounting fields start */
+    and
+    /* Delay accounting fields end */
+    Their values are collected if CONFIG_TASK_DELAY_ACCT is set.

+    These fields are placed between
+    /* Extended accounting fields start */
+    and
+    /* Extended accounting fields end */
+    Their values are collected if CONFIG_TASK_XACCT is set.
+
+Future extension should add fields to the end of the taskstats struct, and
+should not change the relative position of each field within the struct.

+This driver implements support for the IT8705F, IT8712F, IT8716F,
+IT8718F and SiS950 chips.
 
 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.
 
+The IT8712F and IT8716F additionally feature VID inputs, used to report
+the Vcore voltage of the processor. The early IT8712F have 5 VID pins,
+the IT8716F and late IT8712F have 6. They are shared with other functions
+though, so the functionality may not be available on a given system.
+The driver dumbly assume it is there.
+
+The IT8718F also features VID inputs (up to 8 pins) but the value is
+stored in the Super-I/O configuration space. Due to technical limitations,
+this value can currently only be read once at initialization time, so
+the driver won't notice and report changes in the VID value. The two
+upper VID bits share their pins with voltage inputs (in5 and in6) so you
+can't have both on a given board.
+
+The IT8716F, IT8718F and later IT8712F revisions have support for
+2 additional fans. They are not yet supported by the driver.
+
+The IT8716F and IT8718F, and late IT8712F and IT8705F also have optional
+16-bit tachometer counters for fans 1 to 3. This is better (no more fan
+clock divider mess) but not compatible with the older chips and
+revisions. For now, the driver only uses the 16-bit mode on the
+IT8716F and IT8718F.
+
 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

+Description
+-----------
+
+This driver permits reading temperature sensor(s) embedded inside AMD K8 CPUs.
+Official documentation says that it works from revision F of K8 core, but
+in fact it seems to be implemented for all revisions of K8 except the first
+two revisions (SH-B0 and SH-B3).
+
+There can be up to four temperature sensors inside single CPU. The driver
+will auto-detect the sensors and will display only temperatures from
+implemented sensors.
+
+Mapping of /sys files is as follows:
+
+temp1_input - temperature of Core 0 and "place" 0
+temp2_input - temperature of Core 0 and "place" 1
+temp3_input - temperature of Core 1 and "place" 0
+temp4_input - temperature of Core 1 and "place" 1
+
+Temperatures are measured in degrees Celsius and measurement resolution is
+1 degree C. It is expected that future CPU will have better resolution. The
+temperature is updated once a second. Valid temperatures are from -49 to
+206 degrees C.
+
+Temperature known as TCaseMax was specified for processors up to revision E.
+This temperature is defined as temperature between heat-spreader and CPU
+case, so the internal CPU temperature supplied by this driver can be higher.
+There is no easy way how to measure the temperature which will correlate
+with TCaseMax temperature.
+
+For newer revisions of CPU (rev F, socket AM2) there is a mathematically
+computed temperature called TControl, which must be lower than TControlMax.
+
+The relationship is following:
+
+temp1_input - TjOffset*2 < TControlMax,
+
+TjOffset is not yet exported by the driver, TControlMax is usually
+70 degrees C. The rule of the thumb -> CPU temperature should not cross
+60 degrees C too much.

+
+
+Description
+-----------
+
+The VIA VT1211 Super-I/O chip includes complete hardware monitoring
+capabilities. It monitors 2 dedicated temperature sensor inputs (temp1 and
+temp2), 1 dedicated voltage (in5) and 2 fans. Additionally, the chip
+implements 5 universal input channels (UCH1-5) that can be individually
+programmed to either monitor a voltage or a temperature.
+
+This chip also provides manual and automatic control of fan speeds (according
+to the datasheet). The driver only supports automatic control since the manual
+mode doesn't seem to work as advertised in the datasheet. In fact I couldn't
+get manual mode to work at all! Be aware that automatic mode hasn't been
+tested very well (due to the fact that my EPIA M10000 doesn't have the fans
+connected to the PWM outputs of the VT1211 :-().
+
+The following table shows the relationship between the vt1211 inputs and the
+sysfs nodes.

+
+
+Voltage Monitoring
+------------------
+
+Voltages are sampled by an 8-bit ADC with a LSB of ~10mV. The supported input
+range is thus from 0 to 2.60V. Voltage values outside of this range need
+external scaling resistors. This external scaling needs to be compensated for
+via compute lines in sensors.conf, like:
+
+compute inx @*(1+R1/R2), @/(1+R1/R2)
+
+The board level scaling resistors according to VIA's recommendation are as
+follows. And this is of course totally dependent on the actual board
+implementation :-) You will have to find documentation for your own
+motherboard and edit sensors.conf accordingly.

+(2) R1 and R2 for 3.3V (int) are internal to the VT1211 chip and the driver
+    performs the scaling and returns the properly scaled voltage value.
+
+Each measured voltage has an associated low and high limit which triggers an
+alarm when crossed.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are reported in millidegree Celsius. Each measured temperature
+has a high limit which triggers an alarm if crossed. There is an associated
+hysteresis value with each temperature below which the temperature has to drop
+before the alarm is cleared (this is only true for interrupt mode 0). The
+interrupt mode can be forced to 0 in case the BIOS doesn't do it
+automatically. See the 'Module Parameters' section for details.
+
+All temperature channels except temp2 are external. Temp2 is the VT1211
+internal thermal diode and the driver does all the scaling for temp2 and
+returns the temperature in millidegree Celsius. For the external channels
+temp1 and temp3-temp7, scaling depends on the board implementation and needs
+to be performed in userspace via sensors.conf.
+
+Temp1 is an Intel-type thermal diode which requires the following formula to
+convert between sysfs readings and real temperatures:
+
+compute temp1 (@-Offset)/Gain, (@*Gain)+Offset
+
+According to the VIA VT1211 BIOS porting guide, the following gain and offset
+values should be used:
+
+Diode Type      Offset   Gain
+----------      ------   ----
+Intel CPU       88.638   0.9528
+                65.000   0.9686   *)
+VIA C3 Ezra     83.869   0.9528
+VIA C3 Ezra-T   73.869   0.9528
+
+*) This is the formula from the lm_sensors 2.10.0 sensors.conf file. I don't
+know where it comes from or how it was derived, it's just listed here for
+completeness.
+
+Temp3-temp7 support NTC thermistors. For these channels, the driver returns
+the voltages as seen at the individual pins of UCH1-UCH5. The voltage at the
+pin (Vpin) is formed by a voltage divider made of the thermistor (Rth) and a
+scaling resistor (Rs):
+
+Vpin = 2200 * Rth / (Rs + Rth)   (2200 is the ADC max limit of 2200 mV)
+
+The equation for the thermistor is as follows (google it if you want to know
+more about it):
+
+Rth = Ro * exp(B * (1 / T - 1 / To))   (To is 298.15K (25C) and Ro is the
+                                        nominal resistance at 25C)
+
+Mingling the above two equations and assuming Rs = Ro and B = 3435 yields the
+following formula for sensors.conf:
+
+compute tempx 1 / (1 / 298.15 - (` (2200 / @ - 1)) / 3435) - 273.15,
+              2200 / (1 + (^ (3435 / 298.15 - 3435 / (273.15 + @))))
+
+
+Fan Speed Control
+-----------------
+
+The VT1211 provides 2 programmable PWM outputs to control the speeds of 2
+fans. Writing a 2 to any of the two pwm[1-2]_enable sysfs nodes will put the
+PWM controller in automatic mode. There is only a single controller that
+controls both PWM outputs but each PWM output can be individually enabled and
+disabled.
+
+Each PWM has 4 associated distinct output duty-cycles: full, high, low and
+off. Full and off are internally hard-wired to 255 (100%) and 0 (0%),
+respectively. High and low can be programmed via
+pwm[1-2]_auto_point[2-3]_pwm. Each PWM output can be associated with a
+different thermal input but - and here's the weird part - only one set of
+thermal thresholds exist that controls both PWMs output duty-cycles. The
+thermal thresholds are accessible via pwm[1-2]_auto_point[1-4]_temp. Note
+that even though there are 2 sets of 4 auto points each, they map to the same
+registers in the VT1211 and programming one set is sufficient (actually only
+the first set pwm1_auto_point[1-4]_temp is writable, the second set is
+read-only).
+
+PWM Auto Point             PWM Output Duty-Cycle
+------------------------------------------------
+pwm[1-2]_auto_point4_pwm   full speed duty-cycle (hard-wired to 255)
+pwm[1-2]_auto_point3_pwm   high speed duty-cycle
+pwm[1-2]_auto_point2_pwm   low speed duty-cycle
+pwm[1-2]_auto_point1_pwm   off duty-cycle (hard-wired to 0)
+
+Temp Auto Point             Thermal Threshold
+---------------------------------------------
+pwm[1-2]_auto_point4_temp   full speed temp
+pwm[1-2]_auto_point3_temp   high speed temp
+pwm[1-2]_auto_point2_temp   low speed temp
+pwm[1-2]_auto_point1_temp   off temp
+
+Long story short, the controller implements the following algorithm to set the
+PWM output duty-cycle based on the input temperature:
+
+Thermal Threshold             Output Duty-Cycle
+                    (Rising Temp)           (Falling Temp)

+
+Description
+-----------
+
+This driver implements support for the Winbond W83627EHF and W83627EHG
+super I/O chips. We will refer to them collectively as Winbond chips.
+
+The chips implement three temperature sensors, five fan rotation
+speed sensors, ten analog voltage sensors, alarms with beep warnings (control
+unimplemented), and some automatic fan regulation strategies (plus manual
+fan control mode).
+
+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 high limit; 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, 16, 32, 64 or
+128) to give the readings more range or accuracy. The driver sets the most
+suitable fan divisor itself. Some fans might not be present because they
+share pins with other functions.
+
+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.
+
+The driver supports automatic fan control mode known as Thermal Cruise.
+In this mode, the chip attempts to keep the measured temperature in a
+predefined temperature range. If the temperature goes out of range, fan
+is driven slower/faster to reach the predefined range again.
+
+The mode works for fan1-fan4. Mapping of temperatures to pwm outputs is as
+follows:
+
+temp1 -> pwm1
+temp2 -> pwm2
+temp3 -> pwm3
+prog  -> pwm4 (the programmable setting is not supported by the driver)
+
+/sys files
+----------
+
+pwm[1-4] - this file stores PWM duty cycle or DC value (fan speed) in range:
+	   0 (stop) to 255 (full)
+
+pwm[1-4]_enable - this file controls mode of fan/temperature control:
+	* 1 Manual Mode, write to pwm file any value 0-255 (full speed)
+	* 2 Thermal Cruise
+
+Thermal Cruise mode
+-------------------
+
+If the temperature is in the range defined by:
+
+pwm[1-4]_target    - set target temperature, unit millidegree Celcius
+		     (range 0 - 127000)
+pwm[1-4]_tolerance - tolerance, unit millidegree Celcius (range 0 - 15000)
+
+there are no changes to fan speed. Once the temperature leaves the interval,
+fan speed increases (temp is higher) or decreases if lower than desired.
+There are defined steps and times, but not exported by the driver yet.
+
+pwm[1-4]_min_output - minimum fan speed (range 1 - 255), when the temperature
+                      is below defined range.
+pwm[1-4]_stop_time  - how many milliseconds [ms] must elapse to switch
+                      corresponding fan off. (when the temperature was below
+                      defined range).
+
+Note: last two functions are influenced by other control bits, not yet exported
+      by the driver, so a change might not have any effect.

+1. Introduction
 ~~~~~~~~~~~~~~~
 This document describes how to use force feedback devices under Linux. The
 goal is not to support these devices as if they were simple input-only devices
 (as it is already the case), but to really enable the rendering of force
 effects.
-At the moment, only I-Force devices are supported, and not officially. That
-means I had to find out how the protocol works on my own. Of course, the
-information I managed to grasp is far from being complete, and I can not
-guarranty that this driver will work for you.
-This document only describes the force feedback part of the driver for I-Force
-devices. Please read joystick.txt before reading further this document.

 2. Instructions to the user
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Here are instructions on how to compile and use the driver. In fact, this
-driver is the normal iforce, input and evdev drivers written by Vojtech
-Pavlik, plus additions to support force feedback.
+To enable force feedback, you have to:
+
+1. have your kernel configured with evdev and a driver that supports your
+   device.
+2. make sure evdev module is loaded and /dev/input/event* device files are
+   created.
 
 Before you start, let me WARN you that some devices shake violently during the
 initialisation phase. This happens for example with my "AVB Top Shot Pegasus".
 To stop this annoying behaviour, move you joystick to its limits. Anyway, you
-should keep a hand on your device, in order to avoid it to brake down if
+should keep a hand on your device, in order to avoid it to break down if
 something goes wrong.
 
-At the kernel's compilation:
-	- Enable IForce/Serial
-	- Enable Event interface
-
-Compile the modules, install them.
-
-You also need inputattach.
-
-You then need to insert the modules into the following order:
-% modprobe joydev
-% modprobe serport		# Only for serial
-% modprobe iforce
-% modprobe evdev
-% ./inputattach -ifor $2 &	# Only for serial
-If you are using USB, you don't need the inputattach step.
-
-Please check that you have all the /dev/input entries needed:
-cd /dev
-rm js*
-mkdir input
-mknod input/js0 c 13 0
-mknod input/js1 c 13 1
-mknod input/js2 c 13 2
-mknod input/js3 c 13 3
-ln -s input/js0 js0
-ln -s input/js1 js1
-ln -s input/js2 js2
-ln -s input/js3 js3

-mknod input/event1 c 13 65

+   The PCI Express Advanced Error Reporting Driver Guide HOWTO
+		T. Long Nguyen	<tom.l.nguyen@intel.com>
+		Yanmin Zhang	<yanmin.zhang@intel.com>
+				07/29/2006
+
+
+1. Overview
+
+1.1 About this guide
+
+This guide describes the basics of the PCI Express Advanced Error
+Reporting (AER) driver and provides information on how to use it, as
+well as how to enable the drivers of endpoint devices to conform with
+PCI Express AER driver.
+
+1.2 Copyright © Intel Corporation 2006.
+
+1.3 What is the PCI Express AER Driver?
+
+PCI Express error signaling can occur on the PCI Express link itself
+or on behalf of transactions initiated on the link. PCI Express
+defines two error reporting paradigms: the baseline capability and
+the Advanced Error Reporting capability. The baseline capability is
+required of all PCI Express components providing a minimum defined
+set of error reporting requirements. Advanced Error Reporting
+capability is implemented with a PCI Express advanced error reporting
+extended capability structure providing more robust error reporting.
+
+The PCI Express AER driver provides the infrastructure to support PCI
+Express Advanced Error Reporting capability. The PCI Express AER
+driver provides three basic functions:
+
+-	Gathers the comprehensive error information if errors occurred.
+-	Reports error to the users.
+-	Performs error recovery actions.
+
+AER driver only attaches root ports which support PCI-Express AER
+capability.
+
+
+2. User Guide
+
+2.1 Include the PCI Express AER Root Driver into the Linux Kernel
+
+The PCI Express AER Root driver is a Root Port service driver attached
+to the PCI Express Port Bus driver. If a user wants to use it, the driver
+has to be compiled. Option CONFIG_PCIEAER supports this capability. It
+depends on CONFIG_PCIEPORTBUS, so pls. set CONFIG_PCIEPORTBUS=y and
+CONFIG_PCIEAER = y.
+
+2.2 Load PCI Express AER Root Driver
+There is a case where a system has AER support in BIOS. Enabling the AER
+Root driver and having AER support in BIOS may result unpredictable
+behavior. To avoid this conflict, a successful load of the AER Root driver
+requires ACPI _OSC support in the BIOS to allow the AER Root driver to
+request for native control of AER. See the PCI FW 3.0 Specification for
+details regarding OSC usage. Currently, lots of firmwares don't provide
+_OSC support while they use PCI Express. To support such firmwares,
+forceload, a parameter of type bool, could enable AER to continue to
+be initiated although firmwares have no _OSC support. To enable the
+walkaround, pls. add aerdriver.forceload=y to kernel boot parameter line
+when booting kernel. Note that forceload=n by default.
+
+2.3 AER error output
+When a PCI-E AER error is captured, an error message will be outputed to
+console. If it's a correctable error, it is outputed as a warning.
+Otherwise, it is printed as an error. So users could choose different
+log level to filter out correctable error messages.
+
+Below shows an example.
++------ PCI-Express Device Error -----+
+Error Severity          : Uncorrected (Fatal)
+PCIE Bus Error type     : Transaction Layer
+Unsupported Request     : First
+Requester ID            : 0500
+VendorID=8086h, DeviceID=0329h, Bus=05h, Device=00h, Function=00h
+TLB Header:
+04000001 00200a03 05010000 00050100
+
+In the example, 'Requester ID' means the ID of the device who sends
+the error message to root port. Pls. refer to pci express specs for
+other fields.
+
+
+3. Developer Guide
+
+To enable AER aware support requires a software driver to configure
+the AER capability structure within its device and to provide callbacks.
+
+To support AER better, developers need understand how AER does work
+firstly.
+
+PCI Express errors are classified into two types: correctable errors
+and uncorrectable errors. This classification is based on the impacts
+of those errors, which may result in degraded performance or function
+failure.
+
+Correctable errors pose no impacts on the functionality of the
+interface. The PCI Express protocol can recover without any software
+intervention or any loss of data. These errors are detected and
+corrected by hardware. Unlike correctable errors, uncorrectable
+errors impact functionality of the interface. Uncorrectable errors
+can cause a particular transaction or a particular PCI Express link
+to be unreliable. Depending on those error conditions, uncorrectable
+errors are further classified into non-fatal errors and fatal errors.
+Non-fatal errors cause the particular transaction to be unreliable,
+but the PCI Express link itself is fully functional. Fatal errors, on
+the other hand, cause the link to be unreliable.
+
+When AER is enabled, a PCI Express device will automatically send an
+error message to the PCIE root port above it when the device captures
+an error. The Root Port, upon receiving an error reporting message,
+internally processes and logs the error message in its PCI Express
+capability structure. Error information being logged includes storing
+the error reporting agent's requestor ID into the Error Source
+Identification Registers and setting the error bits of the Root Error
+Status Register accordingly. If AER error reporting is enabled in Root
+Error Command Register, the Root Port generates an interrupt if an
+error is detected.
+
+Note that the errors as described above are related to the PCI Express
+hierarchy and links. These errors do not include any device specific
+errors because device specific errors will still get sent directly to
+the device driver.
+
+3.1 Configure the AER capability structure
+
+AER aware drivers of PCI Express component need change the device
+control registers to enable AER. They also could change AER registers,
+including mask and severity registers. Helper function
+pci_enable_pcie_error_reporting could be used to enable AER. See
+section 3.3.
+
+3.2. Provide callbacks
+
+3.2.1 callback reset_link to reset pci express link
+
+This callback is used to reset the pci express physical link when a
+fatal error happens. The root port aer service driver provides a
+default reset_link function, but different upstream ports might
+have different specifications to reset pci express link, so all
+upstream ports should provide their own reset_link functions.
+
+In struct pcie_port_service_driver, a new pointer, reset_link, is
+added.
+
+pci_ers_result_t (*reset_link) (struct pci_dev *dev);
+
+Section 3.2.2.2 provides more detailed info on when to call
+reset_link.
+
+3.2.2 PCI error-recovery callbacks
+
+The PCI Express AER Root driver uses error callbacks to coordinate
+with downstream device drivers associated with a hierarchy in question
+when performing error recovery actions.
+
+Data struct pci_driver has a pointer, err_handler, to point to
+pci_error_handlers who consists of a couple of callback function
+pointers. AER driver follows the rules defined in
+pci-error-recovery.txt except pci express specific parts (e.g.
+reset_link). Pls. refer to pci-error-recovery.txt for detailed
+definitions of the callbacks.
+
+Below sections specify when to call the error callback functions.
+
+3.2.2.1 Correctable errors
+
+Correctable errors pose no impacts on the functionality of
+the interface. The PCI Express protocol can recover without any
+software intervention or any loss of data. These errors do not
+require any recovery actions. The AER driver clears the device's
+correctable error status register accordingly and logs these errors.
+
+3.2.2.2 Non-correctable (non-fatal and fatal) errors
+
+If an error message indicates a non-fatal error, performing link reset
+at upstream is not required. The AER driver calls error_detected(dev,
+pci_channel_io_normal) to all drivers associated within a hierarchy in
+question. for example,
+EndPoint<==>DownstreamPort B<==>UpstreamPort A<==>RootPort.
+If Upstream port A captures an AER error, the hierarchy consists of
+Downstream port B and EndPoint.
+
+A driver may return PCI_ERS_RESULT_CAN_RECOVER,
+PCI_ERS_RESULT_DISCONNECT, or PCI_ERS_RESULT_NEED_RESET, depending on
+whether it can recover or the AER driver calls mmio_enabled as next.
+
+If an error message indicates a fatal error, kernel will broadcast
+error_detected(dev, pci_channel_io_frozen) to all drivers within
+a hierarchy in question. Then, performing link reset at upstream is
+necessary. As different kinds of devices might use different approaches
+to reset link, AER port service driver is required to provide the
+function to reset link. Firstly, kernel looks for if the upstream
+component has an aer driver. If it has, kernel uses the reset_link
+callback of the aer driver. If the upstream component has no aer driver
+and the port is downstream port, we will use the aer driver of the
+root port who reports the AER error. As for upstream ports,
+they should provide their own aer service drivers with reset_link
+function. If error_detected returns PCI_ERS_RESULT_CAN_RECOVER and
+reset_link returns PCI_ERS_RESULT_RECOVERED, the error handling goes
+to mmio_enabled.
+
+3.3 helper functions
+
+3.3.1 int pci_find_aer_capability(struct pci_dev *dev);
+pci_find_aer_capability locates the PCI Express AER capability
+in the device configuration space. If the device doesn't support
+PCI-Express AER, the function returns 0.
+
+3.3.2 int pci_enable_pcie_error_reporting(struct pci_dev *dev);
+pci_enable_pcie_error_reporting enables the device to send error
+messages to root port when an error is detected. Note that devices
+don't enable the error reporting by default, so device drivers need
+call this function to enable it.
+
+3.3.3 int pci_disable_pcie_error_reporting(struct pci_dev *dev);
+pci_disable_pcie_error_reporting disables the device to send error
+messages to root port when an error is detected.
+
+3.3.4 int pci_cleanup_aer_uncorrect_error_status(struct pci_dev *dev);
+pci_cleanup_aer_uncorrect_error_status cleanups the uncorrectable
+error status register.
+
+3.4 Frequent Asked Questions
+
+Q: What happens if a PCI Express device driver does not provide an
+error recovery handler (pci_driver->err_handler is equal to NULL)?
+
+A: The devices attached with the driver won't be recovered. If the
+error is fatal, kernel will print out warning messages. Please refer
+to section 3 for more information.
+
+Q: What happens if an upstream port service driver does not provide
+callback reset_link?
+
+A: Fatal error recovery will fail if the errors are reported by the
+upstream ports who are attached by the service driver.
+
+Q: How does this infrastructure deal with driver that is not PCI
+Express aware?
+
+A: This infrastructure calls the error callback functions of the
+driver when an error happens. But if the driver is not aware of
+PCI Express, the device might not report its own errors to root
+port.
+
+Q: What modifications will that driver need to make it compatible
+with the PCI Express AER Root driver?
+
+A: It could call the helper functions to enable AER in devices and
+cleanup uncorrectable status register. Pls. refer to section 3.3.

+Most of the code in Linux is device drivers, so most of the Linux power
+management code is also driver-specific.  Most drivers will do very little;
+others, especially for platforms with small batteries (like cell phones),
+will do a lot.
+
+This writeup gives an overview of how drivers interact with system-wide
+power management goals, emphasizing the models and interfaces that are
+shared by everything that hooks up to the driver model core.  Read it as
+background for the domain-specific work you'd do with any specific driver.
+
+
+Two Models for Device Power Management
+======================================
+Drivers will use one or both of these models to put devices into low-power
+states:
+
+    System Sleep model:
+	Drivers can enter low power states as part of entering system-wide
+	low-power states like "suspend-to-ram", or (mostly for systems with
+	disks) "hibernate" (suspend-to-disk).
+
+	This is something that device, bus, and class drivers collaborate on
+	by implementing various role-specific suspend and resume methods to
+	cleanly power down hardware and software subsystems, then reactivate
+	them without loss of data.
+
+	Some drivers can manage hardware wakeup events, which make the system
+	leave that low-power state.  This feature may be disabled using the
+	relevant /sys/devices/.../power/wakeup file; enabling it may cost some
+	power usage, but let the whole system enter low power states more often.
+
+    Runtime Power Management model:
+	Drivers may also enter low power states while the system is running,
+	independently of other power management activity.  Upstream drivers
+	will normally not know (or care) if the device is in some low power
+	state when issuing requests; the driver will auto-resume anything
+	that's needed when it gets a request.
+
+	This doesn't have, or need much infrastructure; it's just something you
+	should do when writing your drivers.  For example, clk_disable() unused
+	clocks as part of minimizing power drain for currently-unused hardware.
+	Of course, sometimes clusters of drivers will collaborate with each
+	other, which could involve task-specific power management.
+
+There's not a lot to be said about those low power states except that they
+are very system-specific, and often device-specific.  Also, that if enough
+drivers put themselves into low power states (at "runtime"), the effect may be
+the same as entering some system-wide low-power state (system sleep) ... and
+that synergies exist, so that several drivers using runtime pm might put the
+system into a state where even deeper power saving options are available.
+
+Most suspended devices will have quiesced all I/O:  no more DMA or irqs, no
+more data read or written, and requests from upstream drivers are no longer
+accepted.  A given bus or platform may have different requirements though.
+
+Examples of hardware wakeup events include an alarm from a real time clock,
+network wake-on-LAN packets, keyboard or mouse activity, and media insertion
+or removal (for PCMCIA, MMC/SD, USB, and so on).
+
+
+Interfaces for Entering System Sleep States
+===========================================
+Most of the programming interfaces a device driver needs to know about
+relate to that first model:  entering a system-wide low power state,
+rather than just minimizing power consumption by one device.
+
+
+Bus Driver Methods
+------------------
+The core methods to suspend and resume devices reside in struct bus_type.
+These are mostly of interest to people writing infrastructure for busses
+like PCI or USB, or because they define the primitives that device drivers
+may need to apply in domain-specific ways to their devices:
 
-Device Power Management
+struct bus_type {
+	...
+	int  (*suspend)(struct device *dev, pm_message_t state);
+	int  (*suspend_late)(struct device *dev, pm_message_t state);
 
+	int  (*resume_early)(struct device *dev);
+	int  (*resume)(struct device *dev);
+};
 
-Device power management encompasses two areas - the ability to save
-state and transition a device to a low-power state when the system is
-entering a low-power state; and the ability to transition a device to
-a low-power state while the system is running (and independently of
-any other power management activity). 
+Bus drivers implement those methods as appropriate for the hardware and
+the drivers using it; PCI works differently from USB, and so on.  Not many
+people write bus drivers; most driver code is a "device driver" that
+builds on top of bus-specific framework code.
+
+For more information on these driver calls, see the description later;
+they are called in phases for every device, respecting the parent-child
+sequencing in the driver model tree.  Note that as this is being written,
+only the suspend() and resume() are widely available; not many bus drivers
+leverage all of those phases, or pass them down to lower driver levels.
+
+
+/sys/devices/.../power/wakeup files
+-----------------------------------
+All devices in the driver model have two flags to control handling of
+wakeup events, which are hardware signals that can force the device and/or
+system out of a low power state.  These are initialized by bus or device
+driver code using device_init_wakeup(dev,can_wakeup).
+
+The "can_wakeup" flag just records whether the device (and its driver) can
+physically support wakeup events.  When that flag is clear, the sysfs
+"wakeup" file is empty, and device_may_wakeup() returns false.
+
+For devices that can issue wakeup events, a separate flag controls whether
+that device should try to use its wakeup mechanism.  The initial value of
+device_may_wakeup() will be true, so that the device's "wakeup" file holds
+the value "enabled".  Userspace can change that to "disabled" so that
+device_may_wakeup() returns false; or change it back to "enabled" (so that
+it returns true again).
+
+
+EXAMPLE:  PCI Device Driver Methods
+-----------------------------------
+PCI framework software calls these methods when the PCI device driver bound
+to a device device has provided them:
+
+struct pci_driver {
+	...
+	int  (*suspend)(struct pci_device *pdev, pm_message_t state);
+	int  (*suspend_late)(struct pci_device *pdev, pm_message_t state);
+
+	int  (*resume_early)(struct pci_device *pdev);
+	int  (*resume)(struct pci_device *pdev);
+};
 
+Drivers will implement those methods, and call PCI-specific procedures
+like pci_set_power_state(), pci_enable_wake(), pci_save_state(), and
+pci_restore_state() to manage PCI-specific mechanisms.  (PCI config space
+could be saved during driver probe, if it weren't for the fact that some
+systems rely on userspace tweaking using setpci.)  Devices are suspended
+before their bridges enter low power states, and likewise bridges resume
+before their devices.

+Device drivers generally have at least two interfaces, and the methods
+sketched above are the ones which apply to the lower level (nearer PCI, USB,
+or other bus hardware).  The network and block layers are examples of upper
+level interfaces, as is a character device talking to userspace.
+
+Power management requests normally need to flow through those upper levels,
+which often use domain-oriented requests like "blank that screen".  In
+some cases those upper levels will have power management intelligence that
+relates to end-user activity, or other devices that work in cooperation.
+
+When those interfaces are structured using class interfaces, there is a
+standard way to have the upper layer stop issuing requests to a given
+class device (and restart later):
+
+struct class {
+	...
+	int  (*suspend)(struct device *dev, pm_message_t state);
+	int  (*resume)(struct device *dev);
+};
 
-Methods
+Those calls are issued in specific phases of the process by which the
+system enters a low power "suspend" state, or resumes from it.
+
+
+Calling Drivers to Enter System Sleep States
+============================================
+When the system enters a low power state, each device's driver is asked
+to suspend the device by putting it into state compatible with the target
+system state.  That's usually some version of "off", but the details are
+system-specific.  Also, wakeup-enabled devices will usually stay partly
+functional in order to wake the system.
+
+When the system leaves that low power state, the device's driver is asked
+to resume it.  The suspend and resume operations always go together, and
+both are multi-phase operations.
+
+For simple drivers, suspend might quiesce the device using the class code
+and then turn its hardware as "off" as possible with late_suspend.  The
+matching resume calls would then completely reinitialize the hardware
+before reactivating its class I/O queues.
+
+More power-aware drivers drivers will use more than one device low power
+state, either at runtime or during system sleep states, and might trigger
+system wakeup events.
+
+
+Call Sequence Guarantees
+------------------------
+To ensure that bridges and similar links needed to talk to a device are
+available when the device is suspended or resumed, the device tree is
+walked in a bottom-up order to suspend devices.  A top-down order is
+used to resume those devices.
+
+The ordering of the device tree is defined by the order in which devices
+get registered:  a child can never be registered, probed or resumed before
+its parent; and can't be removed or suspended after that parent.
+
+The policy is that the device tree should match hardware bus topology.
+(Or at least the control bus, for devices which use multiple busses.)
+
+
+Suspending Devices
+------------------
+Suspending a given device is done in several phases.  Suspending the
+system always includes every phase, executing calls for every device
+before the next phase begins.  Not all busses or classes support all
+these callbacks; and not all drivers use all the callbacks.
+
+The phases are seen by driver notifications issued in this order:
+
+   1	class.suspend(dev, message) is called after tasks are frozen, for
+	devices associated with a class that has such a method.  This
+	method may sleep.
+
+	Since I/O activity usually comes from such higher layers, this is
+	a good place to quiesce all drivers of a given type (and keep such
+	code out of those drivers).
+
+   2	bus.suspend(dev, message) is called next.  This method may sleep,
+	and is often morphed into a device driver call with bus-specific
+	parameters and/or rules.
+
+	This call should handle parts of device suspend logic that require
+	sleeping.  It probably does work to quiesce the device which hasn't
+	been abstracted into class.suspend() or bus.suspend_late().
+
+   3	bus.suspend_late(dev, message) is called with IRQs disabled, and
+	with only one CPU active.  Until the bus.resume_early() phase
+	completes (see later), IRQs are not enabled again.  This method
+	won't be exposed by all busses; for message based busses like USB,
+	I2C, or SPI, device interactions normally require IRQs.  This bus
+	call may be morphed into a driver call with bus-specific parameters.
+
+	This call might save low level hardware state that might otherwise
+	be lost in the upcoming low power state, and actually put the
+	device into a low power state ... so that in some cases the device
+	may stay partly usable until this late.  This "late" call may also
+	help when coping with hardware that behaves badly.
+
+The pm_message_t parameter is currently used to refine those semantics
+(described later).
+
+At the end of those phases, drivers should normally have stopped all I/O
+transactions (DMA, IRQs), saved enough state that they can re-initialize
+or restore previous state (as needed by the hardware), and placed the
+device into a low-power state.  On many platforms they will also use
+clk_disable() to gate off one or more clock sources; sometimes they will
+also switch off power supplies, or reduce voltages.  Drivers which have
+runtime PM support may already have performed some or all of the steps
+needed to prepare for the upcoming system sleep state.
+
+When any driver sees that its device_can_wakeup(dev), it should make sure
+to use the relevant hardware signals to trigger a system wakeup event.
+For example, enable_irq_wake() might identify GPIO signals hooked up to
+a switch or other external hardware, and pci_enable_wake() does something
+similar for PCI's PME# signal.
+
+If a driver (or bus, or class) fails it suspend method, the system won't
+enter the desired low power state; it will resume all the devices it's
+suspended so far.
+
+Note that drivers may need to perform different actions based on the target
+system lowpower/sleep state.  At this writing, there are only platform
+specific APIs through which drivers could determine those target states.
+
+
+Device Low Power (suspend) States
+---------------------------------
+Device low-power states aren't very standard.  One device might only handle
+"on" and "off, while another might support a dozen different versions of
+"on" (how many engines are active?), plus a state that gets back to "on"
+faster than from a full "off".
+
+Some busses define rules about what different suspend states mean.  PCI
+gives one example:  after the suspend sequence completes, a non-legacy
+PCI device may not perform DMA or issue IRQs, and any wakeup events it
+issues would be issued through the PME# bus signal.  Plus, there are
+several PCI-standard device states, some of which are optional.
+
+In contrast, integrated system-on-chip processors often use irqs as the
+wakeup event sources (so drivers would call enable_irq_wake) and might
+be able to treat DMA completion as a wakeup event (sometimes DMA can stay
+active too, it'd only be the CPU and some peripherals that sleep).
+
+Some details here may be platform-specific.  Systems may have devices that
+can be fully active in certain sleep states, such as an LCD display that's
+refreshed using DMA while most of the system is sleeping lightly ... and
+its frame buffer might even be updated by a DSP or other non-Linux CPU while
+the Linux control processor stays idle.
+
+Moreover, the specific actions taken may depend on the target system state.
+One target system state might allow a given device to be very operational;
+another might require a hard shut down with re-initialization on resume.
+And two different target systems might use the same device in different
+ways; the aforementioned LCD might be active in one product's "standby",
+but a different product using the same SOC might work differently.
+
+
+Meaning of pm_message_t.event
+-----------------------------
+Parameters to suspend calls include the device affected and a message of
+type pm_message_t, which has one field:  the event.  If driver does not
+recognize the event code, suspend calls may abort the request and return
+a negative errno.  However, most drivers will be fine if they implement
+PM_EVENT_SUSPEND semantics for all messages.
+
+The event codes are used to refine the goal of suspending the device, and
+mostly matter when creating or resuming system memory image snapshots, as
+used with suspend-to-disk:
+
+    PM_EVENT_SUSPEND -- quiesce the driver and put hardware into a low-power
+	state.  When used with system sleep states like "suspend-to-RAM" or
+	"standby", the upcoming resume() call will often be able to rely on
+	state kept in hardware, or issue system wakeup events.  When used
+	instead with suspend-to-disk, few devices support this capability;
+	most are completely powered off.
+
+    PM_EVENT_FREEZE -- quiesce the driver, but don't necessarily change into
+	any low power mode.  A system snapshot is about to be taken, often
+	followed by a call to the driver's resume() method.  Neither wakeup
+	events nor DMA are allowed.
+
+    PM_EVENT_PRETHAW -- quiesce the driver, knowing that the upcoming resume()
+	will restore a suspend-to-disk snapshot from a different kernel image.
+	Drivers that are smart enough to look at their hardware state during
+	resume() processing need that state to be correct ... a PRETHAW could
+	be used to invalidate that state (by resetting the device), like a
+	shutdown() invocation would before a kexec() or system halt.  Other
+	drivers might handle this the same way as PM_EVENT_FREEZE.  Neither
+	wakeup events nor DMA are allowed.
+
+To enter "standby" (ACPI S1) or "Suspend to RAM" (STR, ACPI S3) states, or
+the similarly named APM states, only PM_EVENT_SUSPEND is used; for "Suspend
+to Disk" (STD, hibernate, ACPI S4), all of those event codes are used.
+
+There's also PM_EVENT_ON, a value which never appears as a suspend event
+but is sometimes used to record the "not suspended" device state.
+
+
+Resuming Devices
+----------------
+Resuming is done in multiple phases, much like suspending, with all
+devices processing each phase's calls before the next phase begins.
+
+The phases are seen by driver notifications issued in this order:
+
+   1	bus.resume_early(dev) is called with IRQs disabled, and with
+   	only one CPU active.  As with bus.suspend_late(), this method
+	won't be supported on busses that require IRQs in order to
+	interact with devices.
+
+	This reverses the effects of bus.suspend_late().
+
+   2	bus.resume(dev) is called next.  This may be morphed into a device
+   	driver call with bus-specific parameters; implementations may sleep.
+
+	This reverses the effects of bus.suspend().
+
+   3	class.resume(dev) is called for devices associated with a class
+	that has such a method.  Implementations may sleep.
+
+	This reverses the effects of class.suspend(), and would usually
+	reactivate the device's I/O queue.
+
+At the end of those phases, drivers should normally be as functional as
+they were before suspending:  I/O can be performed using DMA and IRQs, and
+the relevant clocks are gated on.  The device need not be "fully on"; it
+might be in a runtime lowpower/suspend state that acts as if it were.
+
+However, the details here may again be platform-specific.  For example,
+some systems support multiple "run" states, and the mode in effect at
+the end of resume() might not be the one which preceded suspension.
+That means availability of certain clocks or power supplies changed,
+which could easily affect how a driver works.
+
+
+Drivers need to be able to handle hardware which has been reset since the
+suspend methods were called, for example by complete reinitialization.
+This may be the hardest part, and the one most protected by NDA'd documents
+and chip errata.  It's simplest if the hardware state hasn't changed since
+the suspend() was called, but that can't always be guaranteed.
+
+Drivers must also be prepared to notice that the device has been removed
+while the system was powered off, whenever that's physically possible.
+PCMCIA, MMC, USB, Firewire, SCSI, and even IDE are common examples of busses
+where common Linux platforms will see such removal.  Details of how drivers
+will notice and handle such removals are currently bus-specific, and often
+involve a separate thread.
 
-The methods to suspend and resume devices reside in struct bus_type: 
 
-struct bus_type {
-       ...
-       int             (*suspend)(struct device * dev, pm_message_t state);
-       int             (*resume)(struct device * dev);
-};
+Note that the bus-specific runtime PM wakeup mechanism can exist, and might
+be defined to share some of the same driver code as for system wakeup.  For
+example, a bus-specific device driver's resume() method might be used there,
+so it wouldn't only be called from bus.resume() during system-wide wakeup.
+See bus-specific information about how runtime wakeup events are handled.
 
-Each bus driver is responsible implementing these methods, translating
-the call into a bus-specific request and forwarding the call to the
-bus-specific drivers. For example, PCI drivers implement suspend() and
-resume() methods in struct pci_driver. The PCI core is simply
-responsible for translating the pointers to PCI-specific ones and
-calling the low-level driver.
-
-This is done to a) ease transition to the new power management methods
-and leverage the existing PM code in various bus drivers; b) allow
-buses to implement generic and default PM routines for devices, and c)
-make the flow of execution obvious to the reader. 
-
-
-System Power Management
-
-When the system enters a low-power state, the device tree is walked in
-a depth-first fashion to transition each device into a low-power
-state. The ordering of the device tree is guaranteed by the order in
-which devices get registered - children are never registered before
-their ancestors, and devices are placed at the back of the list when
-registered. By walking the list in reverse order, we are guaranteed to
-suspend devices in the proper order. 
-
-Devices are suspended once with interrupts enabled. Drivers are
-expected to stop I/O transactions, save device state, and place the
-device into a low-power state. Drivers may sleep, allocate memory,
-etc. at will. 
-
-Some devices are broken and will inevitably have problems powering
-down or disabling themselves with interrupts enabled. For these
-special cases, they may return -EAGAIN. This will put the device on a
-list to be taken care of later. When interrupts are disabled, before
-we enter the low-power state, their drivers are called again to put
-their device to sleep. 
-
-On resume, the devices that returned -EAGAIN will be called to power
-themselves back on with interrupts disabled. Once interrupts have been
-re-enabled, the rest of the drivers will be called to resume their
-devices. On resume, a driver is responsible for powering back on each
-device, restoring state, and re-enabling I/O transactions for that
-device. 
 
+System Devices
+--------------
 System devices follow a slightly different API, which can be found in
 
 	include/linux/sysdev.h
 	drivers/base/sys.c
 
-System devices will only be suspended with interrupts disabled, and
-after all other devices have been suspended. On resume, they will be
-resumed before any other devices, and also with interrupts disabled.
+System devices will only be suspended with interrupts disabled, and after
+all other devices have been suspended.  On resume, they will be resumed
+before any other devices, and also with interrupts disabled.
 
+That is, IRQs are disabled, the suspend_late() phase begins, then the
+sysdev_driver.suspend() phase, and the system enters a sleep state.  Then
+the sysdev_driver.resume() phase begins, followed by the resume_early()
+phase, after which IRQs are enabled.
 
-Runtime Power Management
-
-Many devices are able to dynamically power down while the system is
-still running. This feature is useful for devices that are not being
-used, and can offer significant power savings on a running system. 
-
-In each device's directory, there is a 'power' directory, which
-contains at least a 'state' file. Reading from this file displays what
-power state the device is currently in. Writing to this file initiates
-a transition to the specified power state, which must be a decimal in
-the range 1-3, inclusive; or 0 for 'On'.
+Code to actually enter and exit the system-wide low power state sometimes
+involves hardware details that are only known to the boot firmware, and
+may leave a CPU running software (from SRAM or flash memory) that monitors
+the system and manages its wakeup sequence.
 
-The PM core will call the ->suspend() method in the bus_type object
-that the device belongs to if the specified state is not 0, or
-->resume() if it is. 
 
-Nothing will happen if the specified state is the same state the
-device is currently in. 
-
-If the device is already in a low-power state, and the specified state
-is another, but different, low-power state, the ->resume() method will
-first be called to power the device back on, then ->suspend() will be
-called again with the new state. 
-
-The driver is responsible for saving the working state of the device
-and putting it into the low-power state specified. If this was
-successful, it returns 0, and the device's power_state field is
-updated. 
-
-The driver must take care to know whether or not it is able to
-properly resume the device, including all step of reinitialization
-necessary. (This is the hardest part, and the one most protected by
-NDA'd documents). 
-
-The driver must also take care not to suspend a device that is
-currently in use. It is their responsibility to provide their own
-exclusion mechanisms.
-
-The runtime power transition happens with interrupts enabled. If a
-device cannot support being powered down with interrupts, it may
-return -EAGAIN (as it would during a system power management
-transition),  but it will _not_ be called again, and the transaction
-will fail.
-
-There is currently no way to know what states a device or driver
-supports a priori. This will change in the future. 
-
-pm_message_t meaning
-
-pm_message_t has two fields. event ("major"), and flags.  If driver
-does not know event code, it aborts the request, returning error. Some
-drivers may need to deal with special cases based on the actual type
-of suspend operation being done at the system level. This is why
-there are flags.
-
-Event codes are:
-
-ON -- no need to do anything except special cases like broken
-HW.
-
-# NOTIFICATION -- pretty much same as ON?
-
-FREEZE -- stop DMA and interrupts, and be prepared to reinit HW from
-scratch. That probably means stop accepting upstream requests, the
-actual policy of what to do with them being 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
-is probably best way to do that.
-
-Transitions are only from a resumed state to a suspended state, never
-between 2 suspended states. (ON -> FREEZE or ON -> SUSPEND can happen,
-FREEZE -> SUSPEND or SUSPEND -> FREEZE can not).
-
-All events are:
-
-[NOTE NOTE NOTE: If you are driver author, you should not care; you
-should only look at event, and ignore flags.]
-
-#Prepare for suspend -- userland is still running but we are going to
-#enter suspend state. This gives drivers chance to load firmware from
-#disk and store it in memory, or do other activities taht require
-#operating userland, ability to kmalloc GFP_KERNEL, etc... All of these
-#are forbiden once the suspend dance is started.. event = ON, flags =
-#PREPARE_TO_SUSPEND
-
-Apm standby -- prepare for APM event. Quiesce devices to make life
-easier for APM BIOS. event = FREEZE, flags = APM_STANDBY
-
-Apm suspend -- same as APM_STANDBY, but it we should probably avoid
-spinning down disks. event = FREEZE, flags = APM_SUSPEND
-
-System halt, reboot -- quiesce devices to make life easier for BIOS. event
-= FREEZE, flags = SYSTEM_HALT or SYSTEM_REBOOT
-
-System shutdown -- at least disks need to be spun down, or data may be
-lost. Quiesce devices, just to make life easier for BIOS. event =
-FREEZE, flags = SYSTEM_SHUTDOWN
-
-Kexec    -- turn off DMAs and put hardware into some state where new
-kernel can take over. event = FREEZE, flags = KEXEC
-
-Powerdown at end of swsusp -- very similar to SYSTEM_SHUTDOWN, except wake
-may need to be enabled on some devices. This actually has at least 3
-subtypes, system can reboot, enter S4 and enter S5 at the end of
-swsusp. event = FREEZE, flags = SWSUSP and one of SYSTEM_REBOOT,
-SYSTEM_SHUTDOWN, SYSTEM_S4
-
-Suspend to ram  -- put devices into low power state. event = SUSPEND,
-flags = SUSPEND_TO_RAM
-
-Freeze for swsusp snapshot -- stop DMA and interrupts. No need to put
-devices into low power mode, but you must be able to reinitialize
-device from scratch in resume method. This has two flavors, its done
-once on suspending kernel, once on resuming kernel. event = FREEZE,
-flags = DURING_SUSPEND or DURING_RESUME
-
-Device detach requested from /sys -- deinitialize device; proably same as
-SYSTEM_SHUTDOWN, I do not understand this one too much. probably event
-= FREEZE, flags = DEV_DETACH.
-
-#These are not really events sent:
-#
-#System fully on -- device is working normally; this is probably never
-#passed to suspend() method... event = ON, flags = 0
-#
-#Ready after resume -- userland is now running, again. Time to free any

+Runtime Power Management
+========================
+Many devices are able to dynamically power down while the system is still
+running. This feature is useful for devices that are not being used, and
+can offer significant power savings on a running system.  These devices
+often support a range of runtime power states, which might use names such
+as "off", "sleep", "idle", "active", and so on.  Those states will in some
+cases (like PCI) be partially constrained by a bus the device uses, and will
+usually include hardware states that are also used in system sleep states.
+
+However, note that if a driver puts a device into a runtime low power state
+and the system then goes into a system-wide sleep state, it normally ought
+to resume into that runtime low power state rather than "full on".  Such
+distinctions would be part of the driver-internal state machine for that
+hardware; the whole point of runtime power management is to be sure that
+drivers are decoupled in that way from the state machine governing phases
+of the system-wide power/sleep state transitions.
+
+
+Power Saving Techniques
+-----------------------
+Normally runtime power management is handled by the drivers without specific
+userspace or kernel intervention, by device-aware use of techniques like:
+
+    Using information provided by other system layers
+	- stay deeply "off" except between open() and close()
+	- if transceiver/PHY indicates "nobody connected", stay "off"
+	- application protocols may include power commands or hints
+
+    Using fewer CPU cycles
+	- using DMA instead of PIO
+	- removing timers, or making them lower frequency
+	- shortening "hot" code paths
+	- eliminating cache misses
+	- (sometimes) offloading work to device firmware
+
+    Reducing other resource costs
+	- gating off unused clocks in software (or hardware)
+	- switching off unused power supplies
+	- eliminating (or delaying/merging) IRQs
+	- tuning DMA to use word and/or burst modes
+
+    Using device-specific low power states
+	- using lower voltages
+	- avoiding needless DMA transfers
+
+Read your hardware documentation carefully to see the opportunities that
+may be available.  If you can, measure the actual power usage and check
+it against the budget established for your project.
+
+
+Examples:  USB hosts, system timer, system CPU
+----------------------------------------------
+USB host controllers make interesting, if complex, examples.  In many cases
+these have no work to do:  no USB devices are connected, or all of them are
+in the USB "suspend" state.  Linux host controller drivers can then disable
+periodic DMA transfers that would otherwise be a constant power drain on the
+memory subsystem, and enter a suspend state.  In power-aware controllers,
+entering that suspend state may disable the clock used with USB signaling,
+saving a certain amount of power.
+
+The controller will be woken from that state (with an IRQ) by changes to the
+signal state on the data lines of a given port, for example by an existing
+peripheral requesting "remote wakeup" or by plugging a new peripheral.  The
+same wakeup mechanism usually works from "standby" sleep states, and on some
+systems also from "suspend to RAM" (or even "suspend to disk") states.
+(Except that ACPI may be involved instead of normal IRQs, on some hardware.)
+
+System devices like timers and CPUs may have special roles in the platform
+power management scheme.  For example, system timers using a "dynamic tick"
+approach don't just save CPU cycles (by eliminating needless timer IRQs),
+but they may also open the door to using lower power CPU "idle" states that
+cost more than a jiffie to enter and exit.  On x86 systems these are states
+like "C3"; note that periodic DMA transfers from a USB host controller will
+also prevent entry to a C3 state, much like a periodic timer IRQ.
+
+That kind of runtime mechanism interaction is common.  "System On Chip" (SOC)
+processors often have low power idle modes that can't be entered unless
+certain medium-speed clocks (often 12 or 48 MHz) are gated off.  When the
+drivers gate those clocks effectively, then the system idle task may be able
+to use the lower power idle modes and thereby increase battery life.
+
+If the CPU can have a "cpufreq" driver, there also may be opportunities
+to shift to lower voltage settings and reduce the power cost of executing
+a given number of instructions.  (Without voltage adjustment, it's rare
+for cpufreq to save much power; the cost-per-instruction must go down.)
+
+
+/sys/devices/.../power/state files
+==================================
+For now you can also test some of this functionality using sysfs.
+
+	DEPRECATED:  USE "power/state" ONLY FOR DRIVER TESTING, AND
+	AVOID USING dev->power.power_state IN DRIVERS.
+
+	THESE WILL BE REMOVED.  IF THE "power/state" FILE GETS REPLACED,
+	IT WILL BECOME SOMETHING COUPLED TO THE BUS OR DRIVER.
+
+In each device's directory, there is a 'power' directory, which contains
+at least a 'state' file.  The value of this field is effectively boolean,
+PM_EVENT_ON or PM_EVENT_SUSPEND.
+
+   *	Reading from this file displays a value corresponding to
+	the power.power_state.event field.  All nonzero values are
+	displayed as "2", corresponding to a low power state; zero
+	is displayed as "0", corresponding to normal operation.
+
+   *	Writing to this file initiates a transition using the
+   	specified event code number; only '0', '2', and '3' are
+	accepted (without a newline); '2' and '3' are both
+	mapped to PM_EVENT_SUSPEND.
+
+On writes, the PM core relies on that recorded event code and the device/bus
+capabilities to determine whether it uses a partial suspend() or resume()
+sequence to change things so that the recorded event corresponds to the
+numeric parameter.
+
+   -	If the bus requires the irqs-disabled suspend_late()/resume_early()
+	phases, writes fail because those operations are not supported here.
+
+   -	If the recorded value is the expected value, nothing is done.
+
+   -	If the recorded value is nonzero, the device is partially resumed,
+	using the bus.resume() and/or class.resume() methods.
+
+   -	If the target value is nonzero, the device is partially suspended,
+	using the class.suspend() and/or bus.suspend() methods and the
+	PM_EVENT_SUSPEND message.
+
+Drivers have no way to tell whether their suspend() and resume() calls
+have come through the sysfs power/state file or as part of entering a
+system sleep state, except that when accessed through sysfs the normal
+parent/child sequencing rules are ignored.  Drivers (such as bus, bridge,
+or hub drivers) which expose child devices may need to enforce those rules
+on their own.

-BSD Secure Levels Linux Security Module
-Michael A. Halcrow <mike@halcrow.us>

-Introduction
-
-Under the BSD Secure Levels security model, sets of policies are
-associated with levels. Levels range from -1 to 2, with -1 being the
-weakest and 2 being the strongest. These security policies are
-enforced at the kernel level, so not even the superuser is able to
-disable or circumvent them. This hardens the machine against attackers
-who gain root access to the system.
-
-
-Levels and Policies
-
-Level -1 (Permanently Insecure):
- - Cannot increase the secure level
-
-Level 0 (Insecure):
- - Cannot ptrace the init process
-
-Level 1 (Default):
- - /dev/mem and /dev/kmem are read-only
- - IMMUTABLE and APPEND extended attributes, if set, may not be unset
- - Cannot load or unload kernel modules
- - Cannot write directly to a mounted block device
- - Cannot perform raw I/O operations
- - Cannot perform network administrative tasks
- - Cannot setuid any file
-
-Level 2 (Secure):
- - Cannot decrement the system time
- - Cannot write to any block device, whether mounted or not
- - Cannot unmount any mounted filesystems
-
-
-Compilation
-
-To compile the BSD Secure Levels LSM, seclvl.ko, enable the
-SECURITY_SECLVL configuration option.  This is found under Security
-options -> BSD Secure Levels in the kernel configuration menu.
-
-
-Basic Usage
-
-Once the machine is in a running state, with all the necessary modules
-loaded and all the filesystems mounted, you can load the seclvl.ko
-module:
-
-# insmod seclvl.ko
-
-The module defaults to secure level 1, except when compiled directly
-into the kernel, in which case it defaults to secure level 0. To raise
-the secure level to 2, the administrator writes ``2'' to the
-seclvl/seclvl file under the sysfs mount point (assumed to be /sys in
-these examples):
-
-# echo -n "2" > /sys/seclvl/seclvl
-
-Alternatively, you can initialize the module at secure level 2 with
-the initlvl module parameter:
-
-# insmod seclvl.ko initlvl=2
-
-At this point, it is impossible to remove the module or reduce the
-secure level.  If the administrator wishes to have the option of doing
-so, he must provide a module parameter, sha1_passwd, that specifies
-the SHA1 hash of the password that can be used to reduce the secure
-level to 0.
-
-To generate this SHA1 hash, the administrator can use OpenSSL:
-
-# echo -n "boogabooga" | openssl sha1
-abeda4e0f33defa51741217592bf595efb8d289c
-
-In order to use password-instigated secure level reduction, the SHA1
-crypto module must be loaded or compiled into the kernel:
-
-# insmod sha1.ko
-
-The administrator can then insmod the seclvl module, including the
-SHA1 hash of the password:
-
-# insmod seclvl.ko
-         sha1_passwd=abeda4e0f33defa51741217592bf595efb8d289c
-
-To reduce the secure level, write the password to seclvl/passwd under
-your sysfs mount point:
-
-# echo -n "boogabooga" > /sys/seclvl/passwd
-
-The September 2004 edition of Sys Admin Magazine has an article about
-the BSD Secure Levels LSM.  I encourage you to refer to that article
-for a more in-depth treatment of this security module:

 Our new imaginary board will also have to tie into the machvec in order for it
-to be of any use. Currently the machvec is slowly on its way out, but is still
-required for the time being. As such, let us take a look at what needs to be
-done for the machvec assignment.
+to be of any use.
 
 machvec functions fall into a number of categories:
 
  - I/O functions to IO memory (inb etc) and PCI/main memory (readb etc).
- - I/O remapping functions (ioremap etc)
- - some initialisation functions
- - a 'heartbeat' function
- - some miscellaneous flags
-
-The tree can be built in two ways:
- - as a fully generic build. All drivers are linked in, and all functions
-   go through the machvec
- - as a machine specific build. In this case only the required drivers
-   will be linked in, and some macros may be redefined to not go through
-   the machvec where performance is important (in particular IO functions).
-
-There are three ways in which IO can be performed:
- - none at all. This is really only useful for the 'unknown' machine type,
-   which us designed to run on a machine about which we know nothing, and
-   so all all IO instructions do nothing.
- - fully custom. In this case all IO functions go to a machine specific
-   set of functions which can do what they like
- - a generic set of functions. These will cope with most situations,
-   and rely on a single function, mv_port2addr, which is called through the
-   machine vector, and converts an IO address into a memory address, which
-   can be read from/written to directly.
-
-Thus adding a new machine involves the following steps (I will assume I am
-adding a machine called vapor):
-
- - add a new file include/asm-sh/vapor/io.h which contains prototypes for
+ - I/O mapping functions (ioport_map, ioport_unmap, etc).
+ - a 'heartbeat' function.
+ - PCI and IRQ initialization routines.
+ - Consistent allocators (for boards that need special allocators,
+   particularly for allocating out of some board-specific SRAM for DMA
+   handles).
+
+There are machvec functions added and removed over time, so always be sure to
+consult include/asm-sh/machvec.h for the current state of the machvec.
+
+The kernel will automatically wrap in generic routines for undefined function
+pointers in the machvec at boot time, as machvec functions are referenced
+unconditionally throughout most of the tree. Some boards have incredibly
+sparse machvecs (such as the dreamcast and sh03), whereas others must define
+virtually everything (rts7751r2d).
+
+Adding a new machine is relatively trivial (using vapor as an example):
+
+If the board-specific definitions are quite minimalistic, as is the case for
+the vast majority of boards, simply having a single board-specific header is
+sufficient.
+
+ - add a new file include/asm-sh/vapor.h which contains prototypes for
    any machine specific IO functions prefixed with the machine name, for
    example vapor_inb. These will be needed when filling out the machine
    vector.
 
-   This is the minimum that is required, however there are ample
-   opportunities to optimise this. In particular, by making the prototypes
-   inline function definitions, it is possible to inline the function when
-   building machine specific versions. Note that the machine vector
-   functions will still be needed, so that a module built for a generic
-   setup can be loaded.
-
- - add a new file arch/sh/boards/vapor/mach.c. This contains the definition
-   of the machine vector. When building the machine specific version, this
-   will be the real machine vector (via an alias), while in the generic
-   version is used to initialise the machine vector, and then freed, by
-   making it initdata. This should be defined as:
-
-     struct sh_machine_vector mv_vapor __initmv = {
-       .mv_name = "vapor",
-     }
-     ALIAS_MV(vapor)
-
- - finally add a file arch/sh/boards/vapor/io.c, which contains
-   definitions of the machine specific io functions.
-
-A note about initialisation functions. Three initialisation functions are
-provided in the machine vector:
- - mv_arch_init - called very early on from setup_arch
- - mv_init_irq - called from init_IRQ, after the generic SH interrupt
-   initialisation
- - mv_init_pci - currently not used
-
-Any other remaining functions which need to be called at start up can be
-added to the list using the __initcalls macro (or module_init if the code
-can be built as a module). Many generic drivers probe to see if the device
-they are targeting is present, however this may not always be appropriate,
-so a flag can be added to the machine vector which will be set on those
-machines which have the hardware in question, reducing the probe to a
-single conditional.
+   Note that these prototypes are generated automatically by setting
+   __IO_PREFIX to something sensible. A typical example would be:
+
+	#define __IO_PREFIX vapor
+   	#include <asm/io_generic.h>
+
+   somewhere in the board-specific header. Any boards being ported that still
+   have a legacy io.h should remove it entirely and switch to the new model.
+
+ - Add machine vector definitions to the board's setup.c. At a bare minimum,
+   this must be defined as something like:
+
+	struct sh_machine_vector mv_vapor __initmv = {
+		.mv_name = "vapor",
+	};
+	ALIAS_MV(vapor)
+
+ - finally add a file arch/sh/boards/vapor/io.c, which contains definitions of
+   the machine specific io functions (if there are enough to warrant it).

+	==========================================
+
+Introduction
+------------
+
+The SH-3 and SH-4 CPU families traditionally include a single partial register
+bank (selected by SR.RB, only r0 ... r7 are banked), whereas other families
+may have more full-featured banking or simply no such capabilities at all.
+
+SR.RB banking
+-------------
+
+In the case of this type of banking, banked registers are mapped directly to
+r0 ... r7 if SR.RB is set to the bank we are interested in, otherwise ldc/stc
+can still be used to reference the banked registers (as r0_bank ... r7_bank)
+when in the context of another bank. The developer must keep the SR.RB value
+in mind when writing code that utilizes these banked registers, for obvious
+reasons. Userspace is also not able to poke at the bank1 values, so these can
+be used rather effectively as scratch registers by the kernel.
+
+Presently the kernel uses several of these registers.
+
+	- r0_bank, r1_bank (referenced as k0 and k1, used for scratch
+	  registers when doing exception handling).
+	- r2_bank (used to track the EXPEVT/INTEVT code)
+		- Used by do_IRQ() and friends for doing irq mapping based off
+		  of the interrupt exception vector jump table offset
+	- r6_bank (global interrupt mask)
+		- The SR.IMASK interrupt handler makes use of this to set the
+		  interrupt priority level (used by local_irq_enable())
+	- r7_bank (current)

+The cx23416 can produce (and the cx23415 can also read) raw YUV output. The
+format of a YUV frame is specific to this chip and is called HM12. 'HM' stands
+for 'Hauppauge Macroblock', which is a misnomer as 'Conexant Macroblock' would
+be more accurate.
+
+The format is YUV 4:2:0 which uses 1 Y byte per pixel and 1 U and V byte per
+four pixels.
+
+The data is encoded as two macroblock planes, the first containing the Y
+values, the second containing UV macroblocks.
+
+The Y plane is divided into blocks of 16x16 pixels from left to right
+and from top to bottom. Each block is transmitted in turn, line-by-line.
+
+So the first 16 bytes are the first line of the top-left block, the
+second 16 bytes are the second line of the top-left block, etc. After
+transmitting this block the first line of the block on the right to the
+first block is transmitted, etc.
+
+The UV plane is divided into blocks of 16x8 UV values going from left
+to right, top to bottom. Each block is transmitted in turn, line-by-line.
+
+So the first 16 bytes are the first line of the top-left block and
+contain 8 UV value pairs (16 bytes in total). The second 16 bytes are the
+second line of 8 UV pairs of the top-left block, etc. After transmitting
+this block the first line of the block on the right to the first block is
+transmitted, etc.
+
+The code below is given as an example on how to convert HM12 to separate
+Y, U and V planes. This code assumes frames of 720x576 (PAL) pixels.
+
+The width of a frame is always 720 pixels, regardless of the actual specified
+width.

+Format of embedded V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data
+=========================================================
+
+This document describes the V4L2_MPEG_STREAM_VBI_FMT_IVTV format of the VBI data
+embedded in an MPEG-2 program stream. This format is in part dictated by some
+hardware limitations of the ivtv driver (the driver for the Conexant cx23415/6
+chips), in particular a maximum size for the VBI data. Anything longer is cut
+off when the MPEG stream is played back through the cx23415.
+
+The advantage of this format is it is very compact and that all VBI data for
+all lines can be stored while still fitting within the maximum allowed size.
+
+The stream ID of the VBI data is 0xBD. The maximum size of the embedded data is
+4 + 43 * 36, which is 4 bytes for a header and 2 * 18 VBI lines with a 1 byte
+header and a 42 bytes payload each. Anything beyond this limit is cut off by
+the cx23415/6 firmware. Besides the data for the VBI lines we also need 36 bits
+for a bitmask determining which lines are captured and 4 bytes for a magic cookie,
+signifying that this data package contains V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data.
+If all lines are used, then there is no longer room for the bitmask. To solve this
+two different magic numbers were introduced:
+
+'itv0': After this magic number two unsigned longs follow. Bits 0-17 of the first
+unsigned long denote which lines of the first field are captured. Bits 18-31 of
+the first unsigned long and bits 0-3 of the second unsigned long are used for the
+second field.
+
+'ITV0': This magic number assumes all VBI lines are captured, i.e. it implicitly
+implies that the bitmasks are 0xffffffff and 0xf.
+
+After these magic cookies (and the 8 byte bitmask in case of cookie 'itv0') the
+captured VBI lines start:
+
+For each line the least significant 4 bits of the first byte contain the data type.
+Possible values are shown in the table below. The payload is in the following 42
+bytes.
+
+Here is the list of possible data types:
+
+#define IVTV_SLICED_TYPE_TELETEXT       0x1     // Teletext (uses lines 6-22 for PAL)
+#define IVTV_SLICED_TYPE_CC             0x4     // Closed Captions (line 21 NTSC)
+#define IVTV_SLICED_TYPE_WSS            0x5     // Wide Screen Signal (line 23 PAL)
+#define IVTV_SLICED_TYPE_VPS            0x7     // Video Programming System (PAL) (line 16)

+Most of the text from Keith Owens, hacked by AK
+
+x86_64 page size (PAGE_SIZE) is 4K.
+
+Like all other architectures, x86_64 has a kernel stack for every
+active thread.  These thread stacks are THREAD_SIZE (2*PAGE_SIZE) big.
+These stacks contain useful data as long as a thread is alive or a
+zombie. While the thread is in user space the kernel stack is empty
+except for the thread_info structure at the bottom.
+
+In addition to the per thread stacks, there are specialized stacks
+associated with each cpu.  These stacks are only used while the kernel
+is in control on that cpu, when a cpu returns to user space the
+specialized stacks contain no useful data.  The main cpu stacks is
+
+* Interrupt stack.  IRQSTACKSIZE
+
+  Used for external hardware interrupts.  If this is the first external
+  hardware interrupt (i.e. not a nested hardware interrupt) then the
+  kernel switches from the current task to the interrupt stack.  Like
+  the split thread and interrupt stacks on i386 (with CONFIG_4KSTACKS),
+  this gives more room for kernel interrupt processing without having
+  to increase the size of every per thread stack.
+
+  The interrupt stack is also used when processing a softirq.
+
+Switching to the kernel interrupt stack is done by software based on a
+per CPU interrupt nest counter. This is needed because x86-64 "IST"
+hardware stacks cannot nest without races.
+
+x86_64 also has a feature which is not available on i386, the ability
+to automatically switch to a new stack for designated events such as
+double fault or NMI, which makes it easier to handle these unusual
+events on x86_64.  This feature is called the Interrupt Stack Table
+(IST).  There can be up to 7 IST entries per cpu. The IST code is an
+index into the Task State Segment (TSS), the IST entries in the TSS
+point to dedicated stacks, each stack can be a different size.
+
+An IST is selected by an non-zero value in the IST field of an
+interrupt-gate descriptor.  When an interrupt occurs and the hardware
+loads such a descriptor, the hardware automatically sets the new stack
+pointer based on the IST value, then invokes the interrupt handler.  If
+software wants to allow nested IST interrupts then the handler must
+adjust the IST values on entry to and exit from the interrupt handler.
+(this is occasionally done, e.g. for debug exceptions)
+
+Events with different IST codes (i.e. with different stacks) can be
+nested.  For example, a debug interrupt can safely be interrupted by an
+NMI.  arch/x86_64/kernel/entry.S::paranoidentry adjusts the stack
+pointers on entry to and exit from all IST events, in theory allowing
+IST events with the same code to be nested.  However in most cases, the
+stack size allocated to an IST assumes no nesting for the same code.
+If that assumption is ever broken then the stacks will become corrupt.
+
+The currently assigned IST stacks are :-
+
+* STACKFAULT_STACK.  EXCEPTION_STKSZ (PAGE_SIZE).
+
+  Used for interrupt 12 - Stack Fault Exception (#SS).
+
+  This allows to recover from invalid stack segments. Rarely
+  happens.
+
+* DOUBLEFAULT_STACK.  EXCEPTION_STKSZ (PAGE_SIZE).
+
+  Used for interrupt 8 - Double Fault Exception (#DF).
+
+  Invoked when handling a exception causes another exception. Happens
+  when the kernel is very confused (e.g. kernel stack pointer corrupt)
+  Using a separate stack allows to recover from it well enough in many
+  cases to still output an oops.
+
+* NMI_STACK.  EXCEPTION_STKSZ (PAGE_SIZE).
+
+  Used for non-maskable interrupts (NMI).
+
+  NMI can be delivered at any time, including when the kernel is in the
+  middle of switching stacks.  Using IST for NMI events avoids making
+  assumptions about the previous state of the kernel stack.
+
+* DEBUG_STACK.  DEBUG_STKSZ
+
+  Used for hardware debug interrupts (interrupt 1) and for software
+  debug interrupts (INT3).
+
+  When debugging a kernel, debug interrupts (both hardware and
+  software) can occur at any time.  Using IST for these interrupts
+  avoids making assumptions about the previous state of the kernel
+  stack.
+
+* MCE_STACK.  EXCEPTION_STKSZ (PAGE_SIZE).
+
+  Used for interrupt 18 - Machine Check Exception (#MC).
+
+  MCE can be delivered at any time, including when the kernel is in the
+  middle of switching stacks.  Using IST for MCE events avoids making
+  assumptions about the previous state of the kernel stack.
+
+For more details see the Intel IA32 or AMD AMD64 architecture manuals.

- *  21-Jul-2004 BJD  Ported to linux 2.6
- *  12-Jul-2004 BJD  Finished re-write and change of API
- *  06-Jul-2004 BJD  Rewrote dma code to try and cope with various problems
- *  23-May-2003 BJD  Created file
- *  19-Aug-2003 BJD  Cleanup, header fix, added URL
- *
- * This file is based on the Sangwook Lee/Samsung patches, re-written due
- * to various ommisions from the code (such as flexible dma configuration)
- * for use with the BAST system board.
- *
- * The re-write is pretty much complete, and should be good enough for any

+ * Semaphores are implemented using a two-way counter:
+ * The "count" variable is decremented for each process
+ * that tries to acquire the semaphore, while the "sleeping"
+ * variable is a count of such acquires.
+ *
+ * Notably, the inline "up()" and "down()" functions can
+ * efficiently test if they need to do any extra work (up
+ * needs to do something only if count was negative before
+ * the increment operation.
+ *
+ * "sleeping" and the contention routine ordering is protected
+ * by the spinlock in the semaphore's waitqueue head.
+ *
+ * Note that these functions are only called when there is
+ * contention on the lock, and as such all this is the
+ * "non-critical" part of the whole semaphore business. The
+ * critical part is the inline stuff in <asm/semaphore.h>
+ * where we want to avoid any extra jumps and calls.

+ * Logic:
+ *  - only on a boundary condition do we need to care. When we go
+ *    from a negative count to a non-negative, we wake people up.

+ * SN Platform Special Memory (mspec) Support
+ *
+ * This driver exports the SN special memory (mspec) facility to user
+ * processes.
+ * There are three types of memory made available thru this driver:
+ * fetchops, uncached and cached.
+ *
+ * Fetchops are atomic memory operations that are implemented in the
+ * memory controller on SGI SN hardware.
+ *
+ * Uncached are used for memory write combining feature of the ia64
+ * cpu.
+ *
+ * Cached are used for areas of memory that are used as cached addresses
+ * on our partition and used as uncached addresses from other partitions.
+ * Due to a design constraint of the SN2 Shub, you can not have processors
+ * on the same FSB perform both a cached and uncached reference to the
+ * same cache line.  These special memory cached regions prevent the
+ * kernel from ever dropping in a TLB entry and therefore prevent the
+ * processor from ever speculating a cache line from this page.

-Version 2, June 1991

-59 Temple Place - Suite 330, Boston, MA  02111-1307, USA
-
-Everyone is permitted to copy and distribute verbatim copies of this license
-document, but changing it is not allowed.
-
-Preamble
-
-The licenses for most software are designed to take away your freedom to 
-share and change it. By contrast, the GNU General Public License is intended
-to guarantee your freedom to share and change free software--to make sure 
-the software is free for all its users. This General Public License applies 
-to most of the Free Software Foundation's software and to any other program 
-whose authors commit to using it. (Some other Free Software Foundation 
-software is covered by the GNU Library General Public License instead.) You 
-can apply it to your programs, too.
-
-When we speak of free software, we are referring to freedom, not price. Our
-General Public Licenses are designed to make sure that you have the freedom 
-to distribute copies of free software (and charge for this service if you 
-wish), that you receive source code or can get it if you want it, that you 
-can change the software or use pieces of it in new free programs; and that 
-you know you can do these things.
-
-To protect your rights, we need to make restrictions that forbid anyone to 
-deny you these rights or to ask you to surrender the rights. These 
-restrictions translate to certain responsibilities for you if you distribute
-copies of the software, or if you modify it.
-
-For example, if you distribute copies of such a program, whether gratis or 
-for a fee, you must give the recipients all the rights that you have. You 
-must make sure that they, too, receive or can get the source code. And you 
-must show them these terms so they know their rights.
- 
-We protect your rights with two steps: (1) copyright the software, and (2) 
-offer you this license which gives you legal permission to copy, distribute 
-and/or modify the software. 
-
-Also, for each author's protection and ours, we want to make certain that 
-everyone understands that there is no warranty for this free software. If 
-the software is modified by someone else and passed on, we want its 
-recipients to know that what they have is not the original, so that any 
-problems introduced by others will not reflect on the original authors' 
-reputations. 
-
-Finally, any free program is threatened constantly by software patents. We 
-wish to avoid the danger that redistributors of a free program will 
-individually obtain patent licenses, in effect making the program 
-proprietary. To prevent this, we have made it clear that any patent must be 
-licensed for everyone's free use or not licensed at all. 
-
-The precise terms and conditions for copying, distribution and modification 
-follow. 
-
-TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-0. This License applies to any program or other work which contains a notice
-   placed by the copyright holder saying it may be distributed under the 
-   terms of this General Public License. The "Program", below, refers to any
-   such program or work, and a "work based on the Program" means either the 
-   Program or any derivative work under copyright law: that is to say, a 
-   work containing the Program or a portion of it, either verbatim or with 
-   modifications and/or translated into another language. (Hereinafter, 
-   translation is included without limitation in the term "modification".) 
-   Each licensee is addressed as "you". 
-
-   Activities other than copying, distribution and modification are not 
-   covered by this License; they are outside its scope. The act of running 
-   the Program is not restricted, and the output from the Program is covered 
-   only if its contents constitute a work based on the Program (independent 
-   of having been made by running the Program). Whether that is true depends
-   on what the Program does. 
-
-1. You may copy and distribute verbatim copies of the Program's source code 
-   as you receive it, in any medium, provided that you conspicuously and 
-   appropriately publish on each copy an appropriate copyright notice and 
-   disclaimer of warranty; keep intact all the notices that refer to this 
-   License and to the absence of any warranty; and give any other recipients 
-   of the Program a copy of this License along with the Program. 
-
-   You may charge a fee for the physical act of transferring a copy, and you 
-   may at your option offer warranty protection in exchange for a fee. 
-
-2. You may modify your copy or copies of the Program or any portion of it, 
-   thus forming a work based on the Program, and copy and distribute such 
-   modifications or work under the terms of Section 1 above, provided that 
-   you also meet all of these conditions: 
-
-   * a) You must cause the modified files to carry prominent notices stating 
-        that you changed the files and the date of any change. 
-
-   * b) You must cause any work that you distribute or publish, that in 
-        whole or in part contains or is derived from the Program or any part 
-        thereof, to be licensed as a whole at no charge to all third parties
-        under the terms of this License. 
-
-   * c) If the modified program normally reads commands interactively when 
-        run, you must cause it, when started running for such interactive 
-        use in the most ordinary way, to print or display an announcement 
-        including an appropriate copyright notice and a notice that there is
-        no warranty (or else, saying that you provide a warranty) and that 
-        users may redistribute the program under these conditions, and 
-        telling the user how to view a copy of this License. (Exception: if 
-        the Program itself is interactive but does not normally print such 
-        an announcement, your work based on the Program is not required to 
-        print an announcement.) 
-
-   These requirements apply to the modified work as a whole. If identifiable 
-   sections of that work are not derived from the Program, and can be 
-   reasonably considered independent and separate works in themselves, then 
-   this License, and its terms, do not apply to those sections when you 
-   distribute them as separate works. But when you distribute the same 
-   sections as part of a whole which is a work based on the Program, the 
-   distribution of the whole must be on the terms of this License, whose 
-   permissions for other licensees extend to the entire whole, and thus to 
-   each and every part regardless of who wrote it. 
-
-   Thus, it is not the intent of this section to claim rights or contest 
-   your rights to work written entirely by you; rather, the intent is to 
-   exercise the right to control the distribution of derivative or 
-   collective works based on the Program. 
-
-   In addition, mere aggregation of another work not based on the Program 
-   with the Program (or with a work based on the Program) on a volume of a 
-   storage or distribution medium does not bring the other work under the 
-   scope of this License. 
-
-3. You may copy and distribute the Program (or a work based on it, under 
-   Section 2) in object code or executable form under the terms of Sections 
-   1 and 2 above provided that you also do one of the following: 
-
-   * a) Accompany it with the complete corresponding machine-readable source 
-        code, which must be distributed under the terms of Sections 1 and 2 
-        above on a medium customarily used for software interchange; or, 
-
-   * b) Accompany it with a written offer, valid for at least three years, 
-        to give any third party, for a charge no more than your cost of 
-        physically performing source distribution, a complete machine-
-        readable copy of the corresponding source code, to be distributed 
-        under the terms of Sections 1 and 2 above on a medium customarily 
-        used for software interchange; or, 
-
-   * c) Accompany it with the information you received as to the offer to 
-        distribute corresponding source code. (This alternative is allowed 
-        only for noncommercial distribution and only if you received the 
-        program in object code or executable form with such an offer, in 
-        accord with Subsection b above.) 
-
-   The source code for a work means the preferred form of the work for 
-   making modifications to it. For an executable work, complete source code 
-   means all the source code for all modules it contains, plus any 
-   associated interface definition files, plus the scripts used to control 
-   compilation and installation of the executable. However, as a special 
-   exception, the source code distributed need not include anything that is 
-   normally distributed (in either source or binary form) with the major 
-   components (compiler, kernel, and so on) of the operating system on which
-   the executable runs, unless that component itself accompanies the 
-   executable. 
-
-   If distribution of executable or object code is made by offering access 
-   to copy from a designated place, then offering equivalent access to copy 
-   the source code from the same place counts as distribution of the source 
-   code, even though third parties are not compelled to copy the source 
-   along with the object code. 
-
-4. You may not copy, modify, sublicense, or distribute the Program except as
-   expressly provided under this License. Any attempt otherwise to copy, 
-   modify, sublicense or distribute the Program is void, and will 
-   automatically terminate your rights under this License. However, parties 
-   who have received copies, or rights, from you under this License will not
-   have their licenses terminated so long as such parties remain in full 
-   compliance. 
-
-5. You are not required to accept this License, since you have not signed 
-   it. However, nothing else grants you permission to modify or distribute 
-   the Program or its derivative works. These actions are prohibited by law 
-   if you do not accept this License. Therefore, by modifying or 
-   distributing the Program (or any work based on the Program), you 
-   indicate your acceptance of this License to do so, and all its terms and
-   conditions for copying, distributing or modifying the Program or works 
-   based on it. 
-
-6. Each time you redistribute the Program (or any work based on the 
-   Program), the recipient automatically receives a license from the 
-   original licensor to copy, distribute or modify the Program subject to 
-   these terms and conditions. You may not impose any further restrictions 
-   on the recipients' exercise of the rights granted herein. You are not 
-   responsible for enforcing compliance by third parties to this License. 
-
-7. If, as a consequence of a court judgment or allegation of patent 
-   infringement or for any other reason (not limited to patent issues), 
-   conditions are imposed on you (whether by court order, agreement or 
-   otherwise) that contradict the conditions of this License, they do not 
-   excuse you from the conditions of this License. If you cannot distribute 
-   so as to satisfy simultaneously your obligations under this License and 
-   any other pertinent obligations, then as a consequence you may not 
-   distribute the Program at all. For example, if a patent license would 
-   not permit royalty-free redistribution of the Program by all those who 
-   receive copies directly or indirectly through you, then the only way you 
-   could satisfy both it and this License would be to refrain entirely from 
-   distribution of the Program. 
-
-   If any portion of this section is held invalid or unenforceable under any
-   particular circumstance, the balance of the section is intended to apply
-   and the section as a whole is intended to apply in other circumstances. 
-
-   It is not the purpose of this section to induce you to infringe any 
-   patents or other property right claims or to contest validity of any 
-   such claims; this section has the sole purpose of protecting the 
-   integrity of the free software distribution system, which is implemented 
-   by public license practices. Many people have made generous contributions
-   to the wide range of software distributed through that system in 
-   reliance on consistent application of that system; it is up to the 
-   author/donor to decide if he or she is willing to distribute software 
-   through any other system and a licensee cannot impose that choice. 
-
-   This section is intended to make thoroughly clear what is believed to be 
-   a consequence of the rest of this License. 
-
-8. If the distribution and/or use of the Program is restricted in certain 
-   countries either by patents or by copyrighted interfaces, the original 
-   copyright holder who places the Program under this License may add an 
-   explicit geographical distribution limitation excluding those countries, 
-   so that distribution is permitted only in or among countries not thus 
-   excluded. In such case, this License incorporates the limitation as if 
-   written in the body of this License. 
-
-9. The Free Software Foundation may publish revised and/or new versions of 
-   the General Public License from time to time. Such new versions will be 
-   similar in spirit to the present version, but may differ in detail to 
-   address new problems or concerns. 
-
-   Each version is given a distinguishing version number. If the Program 
-   specifies a version number of this License which applies to it and "any 
-   later version", you have the option of following the terms and 
-   conditions either of that version or of any later version published by 
-   the Free Software Foundation. If the Program does not specify a version 
-   number of this License, you may choose any version ever published by the 
-   Free Software Foundation. 
-
-10. If you wish to incorporate parts of the Program into other free programs
-    whose distribution conditions are different, write to the author to ask 
-    for permission. For software which is copyrighted by the Free Software 
-    Foundation, write to the Free Software Foundation; we sometimes make 
-    exceptions for this. Our decision will be guided by the two goals of 
-    preserving the free status of all derivatives of our free software and 
-    of promoting the sharing and reuse of software generally. 
-
-   NO WARRANTY
-
-11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 
-    FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 
-    OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 
-    PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER 
-    EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED 
-    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE 
-    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH 
-    YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL 
-    NECESSARY SERVICING, REPAIR OR CORRECTION. 
-
-12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
-    WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 
-    REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR 
-    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL 
-    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM 
-    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED 
-    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF 
-    THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR 
-    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 
-
-END OF TERMS AND CONDITIONS
-
-How to Apply These Terms to Your New Programs
-
-If you develop a new program, and you want it to be of the greatest 
-possible use to the public, the best way to achieve this is to make it free 
-software which everyone can redistribute and change under these terms. 
-
-To do so, attach the following notices to the program. It is safest to 
-attach them to the start of each source file to most effectively convey the
-exclusion of warranty; and each file should have at least the "copyright" 
-line and a pointer to where the full notice is found. 
-
-one line to give the program's name and an idea of what it does.
-Copyright (C) yyyy  name of author
-
-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; either version 2 of the License, or (at your option) 
-any later version.
-
-This program is distributed in the hope that it will be useful, but WITHOUT 
-ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or 
-FITNESS FOR A PARTICULAR PURPOSE.  See the GNU General Public License for 
-more details.
-
-You should have received a copy of the GNU General Public License along with
-this program; if not, write to the Free Software Foundation, Inc., 59 
-Temple Place - Suite 330, Boston, MA  02111-1307, USA.
-
-Also add information on how to contact you by electronic and paper mail. 
-
-If the program is interactive, make it output a short notice like this when 
-it starts in an interactive mode: 
-
-Gnomovision version 69, Copyright (C) year name of author Gnomovision comes 
-with ABSOLUTELY NO WARRANTY; for details type 'show w'.  This is free 
-software, and you are welcome to redistribute it under certain conditions; 
-type 'show c' for details.
-
-The hypothetical commands 'show w' and 'show c' should show the appropriate 
-parts of the General Public License. Of course, the commands you use may be 
-called something other than 'show w' and 'show c'; they could even be 
-mouse-clicks or menu items--whatever suits your program. 
-
-You should also get your employer (if you work as a programmer) or your 
-school, if any, to sign a "copyright disclaimer" for the program, if 
-necessary. Here is a sample; alter the names: 
-
-Yoyodyne, Inc., hereby disclaims all copyright interest in the program 
-'Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-signature of Ty Coon, 1 April 1989
-Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into 
-proprietary programs. If your program is a subroutine library, you may 
-consider it more useful to permit linking proprietary applications with the 
-library. If this is what you want to do, use the GNU Library General Public 
-License instead of this License.

+	  speedup in boot times on multiprocessor machines, and even a
+	  smaller speedup on single processor machines.

+	  some will just not work properly at all, while others might
+	  decide to blow up power supplies with a huge load all at once,
+	  so use this option at your own risk.
+
+	  It is very unwise to use this option if you are not using a
+	  boot process that can handle devices being created in any
+	  order.  A program that can create persistant block and network
+	  device names (like udev) is a good idea if you wish to use
+	  this option.

+ * all the interfaces which were suspended are resumed so that they remain
+ * in the same state as the device.
+ *
+ * If an autosuspend is in progress (@udev->auto_pm is set), the routine
+ * checks first to make sure that neither the device itself or any of its
+ * active interfaces is in use (pm_usage_cnt is greater than 0).  If they
+ * are, the autosuspend fails.
+ *
+ * If the suspend succeeds, the routine recursively queues an autosuspend
+ * request for @udev's parent device, thereby propagating the change up
+ * the device tree.  If all of the parent's children are now suspended,
+ * the parent will autosuspend in turn.
+ *
+ * The suspend method calls are subject to mutual exclusion under control
+ * of @udev's pm_mutex.  Many of these calls are also under the protection
+ * of @udev's device lock (including all requests originating outside the
+ * USB subsystem), but autosuspend requests generated by a child device or
+ * interface driver may not be.  Usbcore will insure that the method calls
+ * do not arrive during bind, unbind, or reset operations.  However, drivers
+ * must be prepared to handle suspend calls arriving at unpredictable times.
+ * The only way to block such calls is to do an autoresume (preventing
+ * autosuspends) while holding @udev's device lock (preventing outside
+ * suspends).

+	  The U132 adapter is a USB to CardBus adapter specifically designed
+	  for PC cards that contain an OHCI host controller. Typical PC cards
+	  are the Orange Mobile 3G Option GlobeTrotter Fusion card. The U132
+	  adapter will *NOT* work with PC cards that do not contain an OHCI
+	  controller.
+
+	  For those PC cards that contain multiple OHCI controllers only ther
+	  first one is used.
+
+	  The driver consists of two modules, the "ftdi-elan" module is a
+	  USB client driver that interfaces to the FTDI chip within ELAN's
+	  USB-to-PCMCIA adapter, and this "u132-hcd" module is a USB host
+	  controller driver that talks to the OHCI controller within the
+	  CardBus cards that are inserted in the U132 adapter.
+
+	  This driver has been tested with a CardBus OHCI USB adapter, and
+	  worked with a USB PEN Drive inserted into the first USB port of
+	  the PCCARD. A rather pointless thing to do, but useful for testing.
+
+	  It is safe to say M here.

+*
+* This program is free software;you can redistribute it and/or

+* published by the Free Software Foundation, version 2.
+*
+*
+* This driver was written by Tony Olech(tony.olech@elandigitalsystems.com)
+* based on various USB host drivers in the 2.6.15 linux kernel
+* with constant reference to the 3rd Edition of Linux Device Drivers
+* published by O'Reilly
+*
+* The U132 adapter is a USB to CardBus adapter specifically designed
+* for PC cards that contain an OHCI host controller. Typical PC cards
+* are the Orange Mobile 3G Option GlobeTrotter Fusion card.
+*
+* The U132 adapter will *NOT *work with PC cards that do not contain
+* an OHCI controller. A simple way to test whether a PC card has an
+* OHCI controller as an interface is to insert the PC card directly
+* into a laptop(or desktop) with a CardBus slot and if "lspci" shows
+* a new USB controller and "lsusb -v" shows a new OHCI Host Controller
+* then there is a good chance that the U132 adapter will support the
+* PC card.(you also need the specific client driver for the PC card)
+*
+* Please inform the Author and Maintainer about any PC cards that
+* contain OHCI Host Controller and work when directly connected to
+* an embedded CardBus slot but do not work when they are connected
+* via an ELAN U132 adapter.

+	  ELAN's Uxxx series of adapters are USB to PCMCIA CardBus adapters.
+	  Currently only the U132 adapter is available.
+
+	  The U132 is specifically designed for CardBus PC cards that contain
+	  an OHCI host controller. Typical PC cards are the Orange Mobile 3G
+	  Option GlobeTrotter Fusion card. The U132 adapter will *NOT* work
+	  with PC cards that do not contain an OHCI controller. To use a U132
+	  adapter you will need this "ftdi-elan" module as well as the "u132-hcd"
+	  module which is a USB host controller driver that talks to the OHCI
+	  controller within CardBus card that are inserted in the U132 adapter.
+
+	  This driver has been tested with a CardBus OHCI USB adapter, and
+	  worked with a USB PEN Drive inserted into the first USB port of
+	  the PCCARD. A rather pointless thing to do, but useful for testing.
+
+	  See also the USB_U132_HCD entry "Elan U132 Adapter Host Controller"
+
+	  It is safe to say M here.

+*
+* This driver was written by Tony Olech(tony.olech@elandigitalsystems.com)
+* based on various USB client drivers in the 2.6.15 linux kernel
+* with constant reference to the 3rd Edition of Linux Device Drivers
+* published by O'Reilly
+*
+* The U132 adapter is a USB to CardBus adapter specifically designed
+* for PC cards that contain an OHCI host controller. Typical PC cards
+* are the Orange Mobile 3G Option GlobeTrotter Fusion card.
+*
+* The U132 adapter will *NOT *work with PC cards that do not contain
+* an OHCI controller. A simple way to test whether a PC card has an
+* OHCI controller as an interface is to insert the PC card directly
+* into a laptop(or desktop) with a CardBus slot and if "lspci" shows
+* a new USB controller and "lsusb -v" shows a new OHCI Host Controller
+* then there is a good chance that the U132 adapter will support the
+* PC card.(you also need the specific client driver for the PC card)
+*
+* Please inform the Author and Maintainer about any PC cards that
+* contain OHCI Host Controller and work when directly connected to
+* an embedded CardBus slot but do not work when they are connected
+* via an ELAN U132 adapter.

+/*
+* Common Header File for the Elan Digital Systems U132 adapter
+* this file should be included by both the "ftdi-u132" and
+* the "u132-hcd" modules.
+*
+* Copyright(C) 2006 Elan Digital Systems Limited
+*(http://www.elandigitalsystems.com)
+*
+* Author and Maintainer - Tony Olech - Elan Digital Systems
+*(tony.olech@elandigitalsystems.com)
+*
+* 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 driver was written by Tony Olech(tony.olech@elandigitalsystems.com)
+* based on various USB client drivers in the 2.6.15 linux kernel
+* with constant reference to the 3rd Edition of Linux Device Drivers
+* published by O'Reilly
+*
+* The U132 adapter is a USB to CardBus adapter specifically designed
+* for PC cards that contain an OHCI host controller. Typical PC cards
+* are the Orange Mobile 3G Option GlobeTrotter Fusion card.
+*
+* The U132 adapter will *NOT *work with PC cards that do not contain
+* an OHCI controller. A simple way to test whether a PC card has an
+* OHCI controller as an interface is to insert the PC card directly
+* into a laptop(or desktop) with a CardBus slot and if "lspci" shows
+* a new USB controller and "lsusb -v" shows a new OHCI Host Controller
+* then there is a good chance that the U132 adapter will support the
+* PC card.(you also need the specific client driver for the PC card)
+*
+* Please inform the Author and Maintainer about any PC cards that
+* contain OHCI Host Controller and work when directly connected to
+* an embedded CardBus slot but do not work when they are connected
+* via an ELAN U132 adapter.
+*
+* The driver consists of two modules, the "ftdi-u132" module is
+* a USB client driver that interfaces to the FTDI chip within
+* the U132 adapter manufactured by Elan Digital Systems, and the
+* "u132-hcd" module is a USB host controller driver that talks
+* to the OHCI controller within CardBus card that are inserted
+* in the U132 adapter.
+*
+* The "ftdi-u132" module should be loaded automatically by the
+* hot plug system when the U132 adapter is plugged in. The module
+* initialises the adapter which mostly consists of synchronising
+* the FTDI chip, before continuously polling the adapter to detect
+* PC card insertions. As soon as a PC card containing a recognised
+* OHCI controller is seen the "ftdi-u132" module explicitly requests
+* the kernel to load the "u132-hcd" module.
+*
+* The "ftdi-u132" module provides the interface to the inserted
+* PC card and the "u132-hcd" module uses the API to send and recieve
+* data. The API features call-backs, so that part of the "u132-hcd"
+* module code will run in the context of one of the kernel threads
+* of the "ftdi-u132" module.

+ *
+ * The device works as an standard CDC device, it has 2 interfaces, the first
+ * one is for firmware access and the second is the serial one.
+ * The protocol is very simply, there are two posibilities reading or writing.
+ * When writting the first urb must have a Header that starts with 0x20 0x29 the
+ * next two bytes must say how much data will be sended.
+ * When reading the process is almost equal except that the header starts with
+ * 0x00 0x20.
+ *
+ * The device simply need some stuff to understand data comming from the usb
+ * buffer: The First and Second byte is used for a Header, the Third and Fourth
+ * tells the  device the amount of information the package holds.
+ * Packages are 60 bytes long Header Stuff.
+ * When writting to the device the first two bytes of the header are 0x20 0x29
+ * When reading the bytes are 0x00 0x20, or 0x00 0x10, there is an strange
+ * situation, when too much data arrives to the device because it sends the data
+ * but with out the header. I will use a simply hack to override this situation,
+ * if there is data coming that does not contain any header, then that is data
+ * that must go directly to the tty, as there is no documentation about if there
+ * is any other control code, I will simply check for the first
+ * one.
+ *
+ * The driver registers himself with the USB-serial core and the USB Core. I had
+ * to implement a probe function agains USB-serial, because other way, the
+ * driver was attaching himself to both interfaces. I have tryed with different
+ * configurations of usb_serial_driver with out exit, only the probe function
+ * could handle this correctly.
+ *
+ * I have taken some info from a Greg Kroah-Hartman article:
+ * http://www.linuxjournal.com/article/6573
+ * And from Linux Device Driver Kit CD, which is a great work, the authors taken
+ * the work to recompile lots of information an knowladge in drivers development
+ * and made it all avaible inside a cd.

- * is no problem, but for the stack. This is handled by not letting
- * main() use the stack at all after fork(). Thus, no function
- * calls - which means inline code for fork too, as otherwise we
- * would use the stack upon exit from 'fork()'.
- *
- * Actually only pause and fork are needed inline, so that there
- * won't be any messing with the stack from main(), but we define

+/*
+ * Helper macros to generate ELF Note structures, which are put into a
+ * PT_NOTE segment of the final vmlinux image.  These are useful for
+ * including name-value pairs of metadata into the kernel binary (or
+ * modules?) for use by external programs.
+ *
+ * Each note has three parts: a name, a type and a desc.  The name is
+ * intended to distinguish the note's originator, so it would be a
+ * company, project, subsystem, etc; it must be in a suitable form for
+ * use in a section name.  The type is an integer which is used to tag
+ * the data, and is considered to be within the "name" namespace (so
+ * "FooCo"'s type 42 is distinct from "BarProj"'s type 42).  The
+ * "desc" field is the actual data.  There are no constraints on the
+ * desc field's contents, though typically they're fairly small.
+ *
+ * All notes from a given NAME are put into a section named
+ * .note.NAME.  When the kernel image is finally linked, all the notes
+ * are packed into a single .notes section, which is mapped into the
+ * PT_NOTE segment.  Because notes for a given name are grouped into
+ * the same section, they'll all be adjacent the output file.
+ *
+ * This file defines macros for both C and assembler use.  Their
+ * syntax is slightly different, but they're semantically similar.
+ *
+ * See the ELF specification for more detail about ELF notes.

- * no other zone modifier bits are set (loners) should be placed in
- * the highest order bits of this field.  This allows us to reduce the
- * extent of the zonelists thus saving space.  For example in the case
- * of three zone modifier bits, we could require up to eight zonelists.
- * If the left most zone modifier is a "loner" then the highest valid
- * zonelist would be four allowing us to allocate only five zonelists.
- * Use the first form for GFP_ZONETYPES when the left most bit is not
- * a "loner", otherwise use the second.

- * There are 4 important states driver can be in:
- * ON     -- driver is working
- * FREEZE -- stop operations and apply whatever policy is applicable to a
- *           suspended driver of that class, freeze queues for block like IDE
- *           does, drop packets for ethernet, etc... stop DMA engine too etc...
- *           so a consistent image can be saved; but do not power any hardware
- *           down.
- * SUSPEND - like FREEZE, but hardware is doing as much powersaving as
- *           possible. Roughly pci D3.
+ * Several driver power state transitions are externally visible, affecting
+ * the state of pending I/O queues and (for drivers that touch hardware)
+ * interrupts, wakeups, DMA, and other hardware state.  There may also be
+ * internal transitions to various low power modes, which are transparent
+ * to the rest of the driver stack (such as a driver that's ON gating off
+ * clocks which are not in active use).
  *
- * Unfortunately, current drivers only recognize numeric values 0 (ON) and 3
- * (SUSPEND).  We'll need to fix the drivers. So yes, putting 3 to all different
- * defines is intentional, and will go away as soon as drivers are fixed.  Also
- * note that typedef is neccessary, we'll probably want to switch to
- *   typedef struct pm_message_t { int event; int flags; } pm_message_t
- * or something similar soon.
+ * One transition is triggered by resume(), after a suspend() call; the
+ * message is implicit:
+ *
+ * ON		Driver starts working again, responding to hardware events
+ * 		and software requests.  The hardware may have gone through
+ * 		a power-off reset, or it may have maintained state from the
+ * 		previous suspend() which the driver will rely on while
+ * 		resuming.  On most platforms, there are no restrictions on
+ * 		availability of resources like clocks during resume().
+ *
+ * Other transitions are triggered by messages sent using suspend().  All
+ * these transitions quiesce the driver, so that I/O queues are inactive.
+ * That commonly entails turning off IRQs and DMA; there may be rules
+ * about how to quiesce that are specific to the bus or the device's type.
+ * (For example, network drivers mark the link state.)  Other details may
+ * differ according to the message:
+ *
+ * SUSPEND	Quiesce, enter a low power device state appropriate for
+ * 		the upcoming system state (such as PCI_D3hot), and enable
+ * 		wakeup events as appropriate.
+ *
+ * FREEZE	Quiesce operations so that a consistent image can be saved;
+ * 		but do NOT otherwise enter a low power device state, and do
+ * 		NOT emit system wakeup events.
+ *
+ * PRETHAW	Quiesce as if for FREEZE; additionally, prepare for restoring
+ * 		the system from a snapshot taken after an earlier FREEZE.
+ * 		Some drivers will need to reset their hardware state instead
+ * 		of preserving it, to ensure that it's never mistaken for the
+ * 		state which that earlier snapshot had set up.
+ *
+ * A minimally power-aware driver treats all messages as SUSPEND, fully
+ * reinitializes its device during resume() -- whether or not it was reset
+ * during the suspend/resume cycle -- and can't issue wakeup events.
+ *
+ * More power-aware drivers may also use low power states at runtime as
+ * well as during system sleep states like PM_SUSPEND_STANDBY.  They may
+ * be able to use wakeup events to exit from runtime low-power states,
+ * or from system low-power states such as standby or suspend-to-RAM.

-	  The sysctl interface provides a means of dynamically changing

-	  interface consists of a system call, but if you say Y to "/proc
-	  file system support", a tree of modifiable sysctl entries will be
-	  generated beneath the /proc/sys directory. They are explained in the
-	  files in <file:Documentation/sysctl/>.  Note that enabling this
-	  option will enlarge the kernel by at least 8 KB.
-
-	  As it is generally a good thing, you should say Y here unless
-	  building a kernel for install/rescue disks or your system is very
-	  limited in memory.
+	  Enable the deprecated sysctl system call.  sys_sysctl uses
+	  binary paths that have been found to be a major pain to maintain
+	  and use.  The interface in /proc/sys is now the primary and what
+	  everyone uses.
+
+	  Nothing has been using the binary sysctl interface for some
+	  time now so nothing should break if you disable sysctl syscall
+	  support, and your kernel will get marginally smaller.
+
+	  Unless you have an application that uses the sys_sysctl interface
+ 	  you should probably say N here.

+ * latency.c: Explicit system-wide latency-expectation infrastructure
+ *
+ * The purpose of this infrastructure is to allow device drivers to set
+ * latency constraint they have and to collect and summarize these
+ * expectations globally. The cummulated result can then be used by
+ * power management and similar users to make decisions that have
+ * tradoffs with a latency component.
+ *
+ * An example user of this are the x86 C-states; each higher C state saves
+ * more power, but has a higher exit latency. For the idle loop power
+ * code to make a good decision which C-state to use, information about
+ * acceptable latencies is required.
+ *
+ * An example announcer of latency is an audio driver that knowns it
+ * will get an interrupt when the hardware has 200 usec of samples
+ * left in the DMA buffer; in that case the driver can set a latency
+ * constraint of, say, 150 usec.
+ *
+ * Multiple drivers can each announce their maximum accepted latency,
+ * to keep these appart, a string based identifier is used.

-		       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	Appendix: How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    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; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) 19yy name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
