+<title>Preface</title>
+	<para>
+	For many types of devices, creating a Linux kernel driver is
+	overkill.  All that is really needed is some way to handle an
+	interrupt and provide access to the memory space of the
+	device.  The logic of controlling the device does not
+	necessarily have to be within the kernel, as the device does
+	not need to take advantage of any of other resources that the
+	kernel provides.  One such common class of devices that are
+	like this are for industrial I/O cards.
+	</para>
+	<para>
+	To address this situation, the userspace I/O system (UIO) was
+	designed.  For typical industrial I/O cards, only a very small
+	kernel module is needed. The main part of the driver will run in
+	user space. This simplifies development and reduces the risk of
+	serious bugs within a kernel module.

+<title>How UIO works</title>
+	<para>
+	Each UIO device is accessed through a device file and several
+	sysfs attribute files. The device file will be called
+	<filename>/dev/uio0</filename> for the first device, and
+	<filename>/dev/uio1</filename>, <filename>/dev/uio2</filename>
+	and so on for subsequent devices.
+	</para>
+
+	<para><filename>/dev/uioX</filename> is used to access the
+	address space of the card. Just use
+	<function>mmap()</function> to access registers or RAM
+	locations of your card.
+	</para>
+
+	<para>
+	Interrupts are handled by reading from
+	<filename>/dev/uioX</filename>. A blocking
+	<function>read()</function> from
+	<filename>/dev/uioX</filename> will return as soon as an
+	interrupt occurs. You can also use
+	<function>select()</function> on
+	<filename>/dev/uioX</filename> to wait for an interrupt. The
+	integer value read from <filename>/dev/uioX</filename>
+	represents the total interrupt count. You can use this number
+	to figure out if you missed some interrupts.
+	</para>
+
+	<para>
+	To handle interrupts properly, your custom kernel module can
+	provide its own interrupt handler. It will automatically be
+	called by the built-in handler.
+	</para>
+
+	<para>
+	For cards that don't generate interrupts but need to be
+	polled, there is the possibility to set up a timer that
+	triggers the interrupt handler at configurable time intervals.
+	See <filename>drivers/uio/uio_dummy.c</filename> for an
+	example of this technique.
+	</para>
+
+	<para>
+	Each driver provides attributes that are used to read or write
+	variables. These attributes are accessible through sysfs
+	files.  A custom kernel driver module can add its own
+	attributes to the device owned by the uio driver, but not added
+	to the UIO device itself at this time.  This might change in the
+	future if it would be found to be useful.
+	</para>
+
+	<para>
+	The following standard attributes are provided by the UIO
+	framework:
+	</para>
+<itemizedlist>
+<listitem>
+	<para>
+	<filename>name</filename>: The name of your device. It is
+	recommended to use the name of your kernel module for this.
+	</para>
+</listitem>
+<listitem>
+	<para>
+	<filename>version</filename>: A version string defined by your
+	driver. This allows the user space part of your driver to deal
+	with different versions of the kernel module.
+	</para>
+</listitem>
+<listitem>
+	<para>
+	<filename>event</filename>: The total number of interrupts
+	handled by the driver since the last time the device node was
+	read.
+	</para>
+</listitem>
+</itemizedlist>
+<para>
+	These attributes appear under the
+	<filename>/sys/class/uio/uioX</filename> directory.  Please
+	note that this directory might be a symlink, and not a real
+	directory.  Any userspace code that accesses it must be able
+	to handle this.
+</para>
+<para>
+	Each UIO device can make one or more memory regions available for
+	memory mapping. This is necessary because some industrial I/O cards
+	require access to more than one PCI memory region in a driver.
+</para>
+<para>
+	Each mapping has its own directory in sysfs, the first mapping
+	appears as <filename>/sys/class/uio/uioX/maps/map0/</filename>.
+	Subsequent mappings create directories <filename>map1/</filename>,
+	<filename>map2/</filename>, and so on. These directories will only
+	appear if the size of the mapping is not 0.
+</para>
+<para>
+	Each <filename>mapX/</filename> directory contains two read-only files
+	that show start address and size of the memory:
+</para>
+<itemizedlist>
+<listitem>

+	Well, there is no real use for uio_dummy. Its only purpose is

+	The kernel module <filename>uio_dummy.ko</filename> creates a

+	interrupts. The default value of <varname>freq</varname> is
+	the value of the kernel variable <varname>HZ</varname>, which
+	gives you an interval of one second. Lower values will
+	increase the frequency. Try the following:

+	<para>
+	What you need to do in your interrupt handler depends on your

+
+	<para>
+	A note on shared interrupts: Your driver should support
+	interrupt sharing whenever this is possible. It is possible if
+	and only if your driver can detect whether your hardware has
+	triggered the interrupt or not. This is usually done by looking
+	at an interrupt status register. If your driver sees that the
+	IRQ bit is actually set, it will perform its actions, and the
+	handler returns IRQ_HANDLED. If the driver detects that it was
+	not your hardware that caused the interrupt, it will do nothing
+	and return IRQ_NONE, allowing the kernel to call the next
+	possible interrupt handler.

+
+	<para>
+	If you decide not to support shared interrupts, your card

+A new feature for EDAC, the edac_device class of device, was added in
+the 2.6.23 version of the kernel.
+
+This new device type allows for non-memory type of ECC hardware detectors
+to have their states harvested and presented to userspace via the sysfs
+interface.
+
+Some architectures have ECC detectors for L1, L2 and L3 caches, along with DMA
+engines, fabric switches, main data path switches, interconnections,
+and various other hardware data paths. If the hardware reports it, then
+a edac_device device probably can be constructed to harvest and present
+that to userspace.

+PCI BUS SCANNING
 
 In addition, PCI Bus Parity and SERR Errors are scanned for on PCI devices
 in order to determine if errors are occurring on data transfers.

+EDAC_DEVICE type of device
+
+In the header file, edac_core.h, there is a series of edac_device structures
+and APIs for the EDAC_DEVICE.
+
+User space access to an edac_device is through the sysfs interface.
+
+At the location /sys/devices/system/edac (sysfs) new edac_device devices will
+appear.
+
+There is a three level tree beneath the above 'edac' directory. For example,
+the 'test_device_edac' device (found at the bluesmoke.sourceforget.net website)
+installs itself as:
+
+	/sys/devices/systm/edac/test-instance
+
+in this directory are various controls, a symlink and one or more 'instance'
+directorys.
+
+The standard default controls are:
+
+	log_ce		boolean to log CE events
+	log_ue		boolean to log UE events
+	panic_on_ue	boolean to 'panic' the system if an UE is encountered
+			(default off, can be set true via startup script)
+	poll_msec	time period between POLL cycles for events
+
+The test_device_edac device adds at least one of its own custom control:
+
+	test_bits	which in the current test driver does nothing but
+			show how it is installed. A ported driver can
+			add one or more such controls and/or attributes
+			for specific uses.
+			One out-of-tree driver uses controls here to allow
+			for ERROR INJECTION operations to hardware
+			injection registers
+
+The symlink points to the 'struct dev' that is registered for this edac_device.
+
+INSTANCES
+
+One or more instance directories are present. For the 'test_device_edac' case:
+
+	test-instance0
+
+
+In this directory there are two default counter attributes, which are totals of
+counter in deeper subdirectories.
+
+	ce_count	total of CE events of subdirectories
+	ue_count	total of UE events of subdirectories
+
+BLOCKS
+
+At the lowest directory level is the 'block' directory. There can be 0, 1
+or more blocks specified in each instance.
+
+	test-block0
+
+
+In this directory the default attributes are:
+
+	ce_count	which is counter of CE events for this 'block'
+			of hardware being monitored
+	ue_count	which is counter of UE events for this 'block'
+			of hardware being monitored
+
+
+The 'test_device_edac' device adds 4 attributes and 1 control:
+
+	test-block-bits-0	for every POLL cycle this counter
+				is incremented
+	test-block-bits-1	every 10 cycles, this counter is bumped once,
+				and test-block-bits-0 is set to 0
+	test-block-bits-2	every 100 cycles, this counter is bumped once,
+				and test-block-bits-1 is set to 0
+	test-block-bits-3	every 1000 cycles, this counter is bumped once,
+				and test-block-bits-2 is set to 0
+
+
+	reset-counters		writing ANY thing to this control will
+				reset all the above counters.
+
+
+Use of the 'test_device_edac' driver should any others to create their own
+unique drivers for their hardware systems.
+
+The 'test_device_edac' sample driver is located at the
+bluesmoke.sourceforge.net project site for EDAC.

+Macintosh HFSPlus Filesystem for Linux
+======================================
+
+HFSPlus is a filesystem first introduced in MacOS 8.1.
+HFSPlus has several extensions to HFS, including 32-bit allocation
+blocks, 255-character unicode filenames, and file sizes of 2^63 bytes.
+
+
+Mount options
+=============
+
+When mounting an HFSPlus filesystem, the following options are accepted:
+
+  creator=cccc, type=cccc
+	Specifies the creator/type values as shown by the MacOS finder
+	used for creating new files.  Default values: '????'.
+
+  uid=n, gid=n
+	Specifies the user/group that owns all files on the filesystem
+	that have uninitialized permissions structures.
+	Default:  user/group id of the mounting process.
+
+  umask=n
+	Specifies the umask (in octal) used for files and directories
+	that have uninitialized permissions structures.
+	Default:  umask of the mounting process.
+
+  session=n
+	Select the CDROM session to mount as HFSPlus filesystem.  Defaults to
+	leaving that decision to the CDROM driver.  This option will fail
+	with anything but a CDROM as underlying devices.
+
+  part=n
+	Select partition number n from the devices.  This option only makes
+	sense for CDROMs because they can't be partitioned under Linux.
+	For disk devices the generic partition parsing code does this
+	for us.  Defaults to not parsing the partition table at all.
+
+  decompose
+	Decompose file name characters.
+
+  nodecompose
+	Do not decompose file name characters.
+
+  force
+	Used to force write access to volumes that are marked as journalled
+	or locked.  Use at your own risk.
+
+  nls=cccc
+	Encoding to use when presenting file names.

+2.15 /proc/<pid>/coredump_filter - Core dump filtering settings
+---------------------------------------------------------------
+When a process is dumped, all anonymous memory is written to a core file as
+long as the size of the core file isn't limited. But sometimes we don't want
+to dump some memory segments, for example, huge shared memory. Conversely,
+sometimes we want to save file-backed memory segments into a core file, not
+only the individual files.
+
+/proc/<pid>/coredump_filter allows you to customize which memory segments
+will be dumped when the <pid> process is dumped. coredump_filter is a bitmask
+of memory types. If a bit of the bitmask is set, memory segments of the
+corresponding memory type are dumped, otherwise they are not dumped.
+
+The following 4 memory types are supported:
+  - (bit 0) anonymous private memory
+  - (bit 1) anonymous shared memory
+  - (bit 2) file-backed private memory
+  - (bit 3) file-backed shared memory
+
+  Note that MMIO pages such as frame buffer are never dumped and vDSO pages
+  are always dumped regardless of the bitmask status.
+
+Default value of coredump_filter is 0x3; this means all anonymous memory
+segments are dumped.
+
+If you don't want to dump all shared memory segments attached to pid 1234,
+write 1 to the process's proc file.
+
+  $ echo 0x1 > /proc/1234/coredump_filter
+
+When a new process is created, the process inherits the bitmask status from its
+parent. It is useful to set up coredump_filter before the program runs.
+For example:
+
+  $ echo 0x7 > /proc/self/coredump_filter
+  $ ./some_program

+Module Parameters
+-----------------
+
+* force_start: bool	Enables the monitoring of voltage, fan and temp inputs
+			and PWM output control functions. Using this parameter
+			shouldn't be required since the BIOS usually takes care
+			of this.
+
+Note that there is no need to use this parameter if the driver loads without
+complaining. The driver will say so if it is necessary.
+
+
+Description
+-----------
+
+This driver implements support for the hardware monitoring capabilities of the
+SMSC DME1737 and Asus A8000 (which are the same) Super-I/O chips. This chip
+features monitoring of 3 temp sensors temp[1-3] (2 remote diodes and 1
+internal), 7 voltages in[0-6] (6 external and 1 internal) and 6 fan speeds
+fan[1-6]. Additionally, the chip implements 5 PWM outputs pwm[1-3,5-6] for
+controlling fan speeds both manually and automatically.
+
+Fan[3-6] and pwm[3,5-6] are optional features and their availability is
+dependent on the configuration of the chip. The driver will detect which
+features are present during initialization and create the sysfs attributes
+accordingly.
+
+
+Voltage Monitoring
+------------------
+
+The voltage inputs are sampled with 12-bit resolution and have internal
+scaling resistors. The values returned by the driver therefore reflect true
+millivolts and don't need scaling. The voltage inputs are mapped as follows
+(the last column indicates the input ranges):
+
+	in0: +5VTR	(+5V standby)		0V - 6.64V
+	in1: Vccp	(processor core)	0V - 3V
+	in2: VCC	(internal +3.3V)	0V - 4.38V
+	in3: +5V				0V - 6.64V
+	in4: +12V				0V - 16V
+	in5: VTR	(+3.3V standby)		0V - 4.38V
+	in6: Vbat	(+3.0V)			0V - 4.38V
+
+Each voltage input has associated min and max limits which trigger an alarm
+when crossed.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are measured with 12-bit resolution and reported in millidegree
+Celsius. The chip also features offsets for all 3 temperature inputs which -
+when programmed - get added to the input readings. The chip does all the
+scaling by itself and the driver therefore reports true temperatures that don't
+need any user-space adjustments. The temperature inputs are mapped as follows
+(the last column indicates the input ranges):
+
+	temp1: Remote diode 1 (3904 type) temperature	-127C - +127C
+	temp2: DME1737 internal temperature		-127C - +127C
+	temp3: Remote diode 2 (3904 type) temperature	-127C - +127C
+
+Each temperature input has associated min and max limits which trigger an alarm
+when crossed. Additionally, each temperature input has a fault attribute that
+returns 1 when a faulty diode or an unconnected input is detected and 0
+otherwise.
+
+
+Fan Monitoring
+--------------
+
+Fan RPMs are measured with 16-bit resolution. The chip provides inputs for 6
+fan tachometers. All 6 inputs have an associated min limit which triggers an
+alarm when crossed. Fan inputs 1-4 provide type attributes that need to be set
+to the number of pulses per fan revolution that the connected tachometer
+generates. Supported values are 1, 2, and 4. Fan inputs 5-6 only support fans
+that generate 2 pulses per revolution. Fan inputs 5-6 also provide a max
+attribute that needs to be set to the maximum attainable RPM (fan at 100% duty-
+cycle) of the input. The chip adjusts the sampling rate based on this value.
+
+
+PWM Output Control
+------------------
+
+This chip features 5 PWM outputs. PWM outputs 1-3 are associated with fan
+inputs 1-3 and PWM outputs 5-6 are associated with fan inputs 5-6. PWM outputs
+1-3 can be configured to operate either in manual or automatic mode by setting
+the appropriate enable attribute accordingly. PWM outputs 5-6 can only operate
+in manual mode, their enable attributes are therefore read-only. When set to
+manual mode, the fan speed is set by writing the duty-cycle value to the
+appropriate PWM attribute. In automatic mode, the PWM attribute returns the
+current duty-cycle as set by the fan controller in the chip. All PWM outputs
+support the setting of the output frequency via the freq attribute.
+
+In automatic mode, the chip supports the setting of the PWM ramp rate which
+defines how fast the PWM output is adjusting to changes of the associated
+temperature input. Associating PWM outputs to temperature inputs is done via
+temperature zones. The chip features 3 zones whose assignments to temperature
+inputs is static and determined during initialization. These assignments can
+be retrieved via the zone[1-3]_auto_channels_temp attributes. Each PWM output
+is assigned to one (or hottest of multiple) temperature zone(s) through the
+pwm[1-3]_auto_channels_zone attributes. Each PWM output has 3 distinct output
+duty-cycles: full, low, and min. Full is internally hard-wired to 255 (100%)
+and low and min can be programmed via pwm[1-3]_auto_point1_pwm and
+pwm[1-3]_auto_pwm_min, respectively. The thermal thresholds of the zones are
+programmed via zone[1-3]_auto_point[1-3]_temp and
+zone[1-3]_auto_point1_temp_hyst:
+
+	pwm[1-3]_auto_point2_pwm	full-speed duty-cycle (255, i.e., 100%)
+	pwm[1-3]_auto_point1_pwm	low-speed duty-cycle
+	pwm[1-3]_auto_pwm_min		min-speed duty-cycle
+
+	zone[1-3]_auto_point3_temp	full-speed temp (all outputs)
+	zone[1-3]_auto_point2_temp	full-speed temp
+	zone[1-3]_auto_point1_temp	low-speed temp
+	zone[1-3]_auto_point1_temp_hyst	min-speed temp
+
+The chip adjusts the output duty-cycle linearly in the range of auto_point1_pwm
+to auto_point2_pwm if the temperature of the associated zone is between
+auto_point1_temp and auto_point2_temp. If the temperature drops below the
+auto_point1_temp_hyst value, the output duty-cycle is set to the auto_pwm_min
+value which only supports two values: 0 or auto_point1_pwm. That means that the
+fan either turns completely off or keeps spinning with the low-speed
+duty-cycle. If any of the temperatures rise above the auto_point3_temp value,
+all PWM outputs are set to 100% duty-cycle.
+
+Following is another representation of how the chip sets the output duty-cycle
+based on the temperature of the associated thermal zone:
+
+			Duty-Cycle	Duty-Cycle
+	Temperature	Rising Temp	Falling Temp
+	-----------	-----------	------------
+	full-speed	full-speed	full-speed
+
+			< linearly adjusted duty-cycle >
+
+	low-speed	low-speed	low-speed
+			min-speed	low-speed
+	min-speed	min-speed	min-speed
+			min-speed	min-speed
+

+Hardware Description
+--------------------
+
+(from the datasheet)
+
+The LM93, hardware monitor, has a two wire digital interface compatible with
+SMBus 2.0. Using an 8-bit ADC, the LM93 measures the temperature of two remote
+diode connected transistors as well as its own die and 16 power supply
+voltages. To set fan speed, the LM93 has two PWM outputs that are each
+controlled by up to four temperature zones. The fancontrol algorithm is lookup
+table based. The LM93 includes a digital filter that can be invoked to smooth
+temperature readings for better control of fan speed. The LM93 has four
+tachometer inputs to measure fan speed. Limit and status registers for all
+measured values are included. The LM93 builds upon the functionality of
+previous motherboard management ASICs and uses some of the LM85 s features
+(i.e. smart tachometer mode). It also adds measurement and control support
+for dynamic Vccp monitoring and PROCHOT. It is designed to monitor a dual
+processor Xeon class motherboard with a minimum of external components.
+
+
+Driver Description
+------------------
+
+This driver implements support for the National Semiconductor LM93.
+
+
+User Interface
+--------------
+
+#PROCHOT:
+
+The LM93 can monitor two #PROCHOT signals.  The results are found in the
+sysfs files prochot1, prochot2, prochot1_avg, prochot2_avg, prochot1_max,
+and prochot2_max.  prochot1_max and prochot2_max contain the user limits
+for #PROCHOT1 and #PROCHOT2, respectively.  prochot1 and prochot2 contain
+the current readings for the most recent complete time interval.  The
+value of prochot1_avg and prochot2_avg is something like a 2 period
+exponential moving average (but not quite - check the datasheet). Note
+that this third value is calculated by the chip itself.  All values range
+from 0-255 where 0 indicates no throttling, and 255 indicates > 99.6%.
+
+The monitoring intervals for the two #PROCHOT signals is also configurable.
+These intervals can be found in the sysfs files prochot1_interval and
+prochot2_interval.  The values in these files specify the intervals for
+#P1_PROCHOT and #P2_PROCHOT, respectively.  Selecting a value not in this
+list will cause the driver to use the next largest interval.  The available
+intervals are:
+
+#PROCHOT intervals: 0.73, 1.46, 2.9, 5.8, 11.7, 23.3, 46.6, 93.2, 186, 372
+
+It is possible to configure the LM93 to logically short the two #PROCHOT
+signals.  I.e. when #P1_PROCHOT is asserted, the LM93 will automatically
+assert #P2_PROCHOT, and vice-versa.  This mode is enabled by writing a
+non-zero integer to the sysfs file prochot_short.
+
+The LM93 can also override the #PROCHOT pins by driving a PWM signal onto
+one or both of them.  When overridden, the signal has a period of 3.56 mS,
+a minimum pulse width of 5 clocks (at 22.5kHz => 6.25% duty cycle), and
+a maximum pulse width of 80 clocks (at 22.5kHz => 99.88% duty cycle).
+
+The sysfs files prochot1_override and prochot2_override contain boolean
+intgers which enable or disable the override function for #P1_PROCHOT and
+#P2_PROCHOT, respectively.  The sysfs file prochot_override_duty_cycle
+contains a value controlling the duty cycle for the PWM signal used when
+the override function is enabled.  This value ranges from 0 to 15, with 0
+indicating minimum duty cycle and 15 indicating maximum.
+
+#VRD_HOT:
+
+The LM93 can monitor two #VRD_HOT signals. The results are found in the
+sysfs files vrdhot1 and vrdhot2. There is one value per file: a boolean for
+which 1 indicates #VRD_HOT is asserted and 0 indicates it is negated. These
+files are read-only.
+
+Smart Tach Mode:
+
+(from the datasheet)
+
+	If a fan is driven using a low-side drive PWM, the tachometer
+	output of the fan is corrupted. The LM93 includes smart tachometer
+	circuitry that allows an accurate tachometer reading to be
+	achieved despite the signal corruption.  In smart tach mode all
+	four signals are measured within 4 seconds.
+
+Smart tach mode is enabled by the driver by writing 1 or 2 (associating the
+the fan tachometer with a pwm) to the sysfs file fan<n>_smart_tach.  A zero
+will disable the function for that fan.  Note that Smart tach mode cannot be
+enabled if the PWM output frequency is 22500 Hz (see below).
+
+Manual PWM:
+
+The LM93 has a fixed or override mode for the two PWM outputs (although, there
+are still some conditions that will override even this mode - see section
+15.10.6 of the datasheet for details.)  The sysfs files pwm1_override
+and pwm2_override are used to enable this mode; each is a boolean integer
+where 0 disables and 1 enables the manual control mode.  The sysfs files pwm1
+and pwm2 are used to set the manual duty cycle; each is an integer (0-255)
+where 0 is 0% duty cycle, and 255 is 100%.  Note that the duty cycle values
+are constrained by the hardware. Selecting a value which is not available
+will cause the driver to use the next largest value.  Also note: when manual
+PWM mode is disabled, the value of pwm1 and pwm2 indicates the current duty
+cycle chosen by the h/w.
+
+PWM Output Frequency:
+
+The LM93 supports several different frequencies for the PWM output channels.
+The sysfs files pwm1_freq and pwm2_freq are used to select the frequency. The
+frequency values are constrained by the hardware.  Selecting a value which is
+not available will cause the driver to use the next largest value.  Also note
+that this parameter has implications for the Smart Tach Mode (see above).
+
+PWM Output Frequencies: 12, 36, 48, 60, 72, 84, 96, 22500 (h/w default)
+
+Automatic PWM:
+
+The LM93 is capable of complex automatic fan control, with many different
+points of configuration.  To start, each PWM output can be bound to any
+combination of eight control sources.  The final PWM is the largest of all
+individual control sources to which the PWM output is bound.
+
+The eight control sources are: temp1-temp4 (aka "zones" in the datasheet),
+#PROCHOT 1 & 2, and #VRDHOT 1 & 2.  The bindings are expressed as a bitmask
+in the sysfs files pwm<n>_auto_channels, where a "1" enables the binding, and
+ a "0" disables it. The h/w default is 0x0f (all temperatures bound).
+
+	0x01 - Temp 1
+	0x02 - Temp 2
+	0x04 - Temp 3
+	0x08 - Temp 4
+	0x10 - #PROCHOT 1
+	0x20 - #PROCHOT 2
+	0x40 - #VRDHOT 1
+	0x80 - #VRDHOT 2
+
+The function y = f(x) takes a source temperature x to a PWM output y.  This
+function of the LM93 is derived from a base temperature and a table of 12
+temperature offsets.  The base temperature is expressed in degrees C in the
+sysfs files temp<n>_auto_base.  The offsets are expressed in cumulative
+degrees C, with the value of offset <i> for temperature value <n> being
+contained in the file temp<n>_auto_offset<i>.  E.g. if the base temperature
+is 40C:
+
+     offset #	temp<n>_auto_offset<i>	range		pwm
+	 1		0		-		 25.00%
+	 2		0		-		 28.57%
+	 3		1		40C - 41C	 32.14%
+	 4		1		41C - 42C	 35.71%
+	 5		2		42C - 44C	 39.29%
+	 6		2		44C - 46C	 42.86%
+	 7		2		48C - 50C	 46.43%
+	 8		2		50C - 52C	 50.00%
+	 9		2		52C - 54C	 53.57%
+	10		2		54C - 56C	 57.14%
+	11		2		56C - 58C	 71.43%
+	12		2		58C - 60C	 85.71%
+					> 60C		100.00%
+
+Valid offsets are in the range 0C <= x <= 7.5C in 0.5C increments.
+
+There is an independent base temperature for each temperature channel. Note,
+however, there are only two tables of offsets: one each for temp[12] and
+temp[34].  Therefore, any change to e.g. temp1_auto_offset<i> will also
+affect temp2_auto_offset<i>.
+
+The LM93 can also apply hysteresis to the offset table, to prevent unwanted
+oscillation between two steps in the offsets table.  These values are found in
+the sysfs files temp<n>_auto_offset_hyst.  The value in this file has the
+same representation as in temp<n>_auto_offset<i>.
+
+If a temperature reading falls below the base value for that channel, the LM93
+will use the minimum PWM value.  These values are found in the sysfs files
+temp<n>_auto_pwm_min.  Note, there are only two minimums: one each for temp[12]
+and temp[34].  Therefore, any change to e.g. temp1_auto_pwm_min will also
+affect temp2_auto_pwm_min.
+
+PWM Spin-Up Cycle:
+
+A spin-up cycle occurs when a PWM output is commanded from 0% duty cycle to
+some value > 0%.  The LM93 supports a minimum duty cycle during spin-up.  These
+values are found in the sysfs files pwm<n>_auto_spinup_min. The value in this
+file has the same representation as other PWM duty cycle values. The
+duration of the spin-up cycle is also configurable.  These values are found in
+the sysfs files pwm<n>_auto_spinup_time. The value in this file is
+the spin-up time in seconds.  The available spin-up times are constrained by
+the hardware.  Selecting a value which is not available will cause the driver
+to use the next largest value.
+
+Spin-up Durations: 0 (disabled, h/w default), 0.1, 0.25, 0.4, 0.7, 1.0,
+		   2.0, 4.0
+
+#PROCHOT and #VRDHOT PWM Ramping:
+
+If the #PROCHOT or #VRDHOT signals are asserted while bound to a PWM output
+channel, the LM93 will ramp the PWM output up to 100% duty cycle in discrete
+steps. The duration of each step is configurable. There are two files, with
+one value each in seconds: pwm_auto_prochot_ramp and pwm_auto_vrdhot_ramp.
+The available ramp times are constrained by the hardware.  Selecting a value
+which is not available will cause the driver to use the next largest value.
+
+Ramp Times: 0 (disabled, h/w default) to 0.75 in 0.05 second intervals
+
+Fan Boost:
+
+For each temperature channel, there is a boost temperature: if the channel
+exceeds this limit, the LM93 will immediately drive both PWM outputs to 100%.
+This limit is expressed in degrees C in the sysfs files temp<n>_auto_boost.
+There is also a hysteresis temperature for this function: after the boost
+limit is reached, the temperature channel must drop below this value before
+the boost function is disabled.  This temperature is also expressed in degrees
+C in the sysfs files temp<n>_auto_boost_hyst.
+
+GPIO Pins:
+
+The LM93 can monitor the logic level of four dedicated GPIO pins as well as the
+four tach input pins.  GPIO0-GPIO3 correspond to (fan) tach 1-4, respectively.
+All eight GPIOs are read by reading the bitmask in the sysfs file gpio.  The
+LSB is GPIO0, and the MSB is GPIO7.

+Module Parameters
+-----------------
+
+* adm1022_temp3: short array
+  List of adapter,address pairs to force chips into ADM1022 mode with
+  second remote temperature. This does not work for original THMC50 chips.
+
+Description
+-----------
+
+The THMC50 implements: an internal temperature sensor, support for an
+external diode-type temperature sensor (compatible w/ the diode sensor inside
+many processors), and a controllable fan/analog_out DAC. For the temperature
+sensors, limits can be set through the appropriate Overtemperature Shutdown
+register and Hysteresis register. Each value can be set and read to half-degree
+accuracy.  An alarm is issued (usually to a connected LM78) when the
+temperature gets higher then the Overtemperature Shutdown value; it stays on
+until the temperature falls below the Hysteresis value. All temperatures are in
+degrees Celsius, and are guaranteed within a range of -55 to +125 degrees.
+
+The THMC50 only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+
+The THMC50 is usually used in combination with LM78-like chips, to measure
+the temperature of the processor(s).
+
+The ADM1022 works the same as THMC50 but it is faster (5 Hz instead of
+1 Hz for THMC50). It can be also put in a new mode to handle additional
+remote temperature sensor. The driver use the mode set by BIOS by default.
+
+In case the BIOS is broken and the mode is set incorrectly, you can force
+the mode with additional remote temperature with adm1022_temp3 parameter.
+A typical symptom of wrong setting is a fan forced to full speed.
+
+Driver Features
+---------------
+
+The driver provides up to three temperatures:
+
+temp1		-- internal
+temp2		-- remote
+temp3		-- 2nd remote only for ADM1022
+
+pwm1		-- fan speed (0 = stop, 255 = full)
+pwm1_mode	-- always 0 (DC mode)
+
+The value of 0 for pwm1 also forces FAN_OFF signal from the chip,
+so it stops fans even if the value 0 into the ANALOG_OUT register does not.
+
+The driver was tested on Compaq AP550 with two ADM1022 chips (one works
+in the temp3 mode), five temperature readings and two fans.

+들었는가? � 문서는 여러분� 겪게 � 과정과 커뮤니티와 �하는 법�
+조언하여 여러분� 목�� 달성하기 위해 필요한 것 모�를 알려주는
+것�다.
+
+커�� 대부분� C로 작성�었어고 몇몇 아키��� �존�� 부분�
+어셈블리로 작성�었다. 커� 개발� 위해 C를 잘 �해하고 있어야 한다.
+여러분� 특정 아키��� low-level 개발� 할 것� 아니�면
+어셈블리(특정 아키��)는 잘 알아야 할 필요는 없다.
+다�� 참고서�들� 기본� 충실한 C �육�나 수년간� 경험� 견주지는
+못하지만 �어� 참고 용�로는 좋� 것�다
+ - "The C Programming Language" by Kernighan and Ritchie [Prentice Hall]
+ - "Practical C Programming" by Steve Oualline [O'Reilly]
+ - "C:  A Reference Manual" by Harbison and Steele [Prentice Hall]
+
+커�� GNU C와 GNU 툴체�� 사용하여 작성�었다. � 툴들� ISO C89 표준�
+따르는 반면 표준� 있지 않� 많� 확장기능� 가지고 있다. 커�� 표준 C
+��브러리와는 관계없� freestanding C 환경�어서 C 표준� �부는
+지��지 않는다. 임�� long long 나누기나 floating point는 지��지 않는다.
+때론 �런 �유로 커�� 그런 확장 기능� 가진 툴체�� 가지고 만들어졌다는
+것� �해하기 어려울 수� 있고 게다가 불행하게� 그런 것� 정확하게 설명하는
+어떤 참고문서� 있지 않다. 정보를 얻기 위해서는 gcc info (`info gcc`)페�지를
+살펴보�.
+
+여러분� 기존� 개발 커뮤니티와 �하는 법� 배우려고 하고 있다는 것�
+기억하�. 코딩, 스타�, 절차� 관한 훌륭한 표준� 가진 사람들� 모�
+다양한 그룹� 있다. � 표준들� 오랜�안 �고 지역�으로 분산� 팀들�
+�해 가장 좋� 방법으로 �하기위하여 찾� 것� 기초로 만들어져왔다.
+그 표준들� 문서화가 잘 �어 있기 때문� 가능한한 미리 많� 표준들�
+관하여 배우려고 시�하�. 다른 사람들� 여러분�나 여러분� 회사가
+�하는 방�� ��하는 것� �하지는 않는다.

+
+개발 프로세스
+-------------
+
+리눅스 커� 개발 프로세스는 현재 몇몇 다른 메� 커� "브랜치들"과
+서브시스템� 특화� 커� 브랜치들로 구성�다. 몇몇 다른 메�
+브랜치들� 다�과 같다.
+  - main 2.6.x 커� 트리
+  - 2.6.x.y - 안정� 커� 트리
+  - 2.6.x -git 커� 패치들
+  - 2.6.x -mm 커� 패치들
+  - 서브시스템� 위한 커� 트리들과 패치들
+
+2.6.x 커� 트리
+---------------
+
+2.6.x 커�들� Linux Torvalds가 관리하며 kernel.org� pub/linux/kernel/v2.6/
+디렉토리�서 참조� 수 있다.개발 프로세스는 다�과 같다.
+  - 새로운 커�� 배���마� 2주� 시간� 주어진다. � 기간��
+    메�트너들� � diff들� Linus�게 제출할 수 있다. 대개 � 패치들�
+    몇 주 �안 -mm 커�내� �미 있었� 것들�다. � 변경들� 제출하는 �
+    선호�는 방법�  git(커�� 소스 관리 툴, � 많� 정보들� http://git.or.cz/
+    �서 참조할 수 있다)를 사용하는 것�지만 순수한 패치파�� 형�으로 보내�
+    것� 무관하다.
+  - 2주 후� -rc1 커�� 배��며 지금부터는 전체 커�� 안정성� �향�
+    미칠수 있는 새로운 기능들� �함하지 않는 패치들만� 추가� 수 있다.
+    완전히 새로운 드��버(혹� 파�시스템)는 -rc1 �후�만 받아들여진다는
+    것� 기억해�. 왜�하면 변경� �체내�서만 발�하고 추가� 코드가
+    드��버 외부� 다른 부분�는 �향� 주지 않으므로 그런 변경�
+    퇴보(regression)를 �으킬 만한 위험� 가지고 있지 않기 때문�다. -rc1�
+    배�� �후� git를 사용하여 패치들� Linus�게 보낼수 있지만 패치들�
+    공��� 메�� 리스트로 보내서 검토를 받� 필요가 있다.
+  - 새로운 -rc는 Linus는 현재 git tree가 테스트 하기� 충분히 안정� �태�
+    있다고 �단� 때마다 배��다. 목표는 새로운 -rc 커�� 매주 배�하는
+    것�다.
+  - �러한 프로세스는 커�� "준비"�었다고 여겨질때까지 계��다.
+    프로세스는 대체로 6주간 지��다.
+    - � -rc 배�� 있는 알려진 퇴보� 목�들� 다� URI� 남겨진다.
+    http://kernelnewbies.org/known_regressions
+
+커� 배�� 있어서 언급할만한 가치가 있는 리눅스 커� 메�� 리스트�
+Andrew Morton� 글� 있다.
+        "커�� 언제 배��지는 아무로 모른다. 왜�하면 배�는 알려진
+         버그� �황� 따� 배��는 것�지 미리정해 놓� 시간� 따�
+          배��는 것� 아니기 때문�다."
+
+2.6.x.y - 안정 커� 트리
+------------------------
+
+4 �리 숫�로 �루어진 버젼� 커�들� -stable 커�들�다. 그것들� 2.6.x
+커��서 발견� � 퇴보들�나 보안 문제들 중 비�� 작고 중요한 수정들�
+�함한다.
+
+�것� 가장 최근� 안정�� 커�� �하는 사용��게 추천�는 브랜치�며,
+개발/실험� 버젼� 테스트하는 것� �는�는 별로 관심� 없다.
+
+어떤 2.6.x.y 커�� 사용가능하지 않다면 그때는 가장 높� 숫�� 2.6.x
+커�� 현재� 안정 커��다.
+
+2.6.x.y는 "stable" 팀<stable@kernel.org>� �해 관리�며 거� 매번 격주로
+배��다.
+
+커� 트리 문서들 내� Documentation/stable_kernel_rules.txt 파�� 어떤
+종류� 변경들� -stable 트리로 들어왔는지와 배� 프로세스가 어떻게
+진행�는지를 설명한다.
+
+
+2.6.x -git 패치들
+------------------
+git 저장소(그러므로 -git��는 �름� 붙�)�는 날마다 관리�는 Linus�
+커� 트리� snapshot 들� 있다. � 패치들� �반�으로 날마다 배��며
+Linus� 트리� 현재 �태를 나타낸다. � 패치들� 정���지 조금�
+살펴보지 않고 ���으로 �성� 것�므로 -rc 커�들 보다� � 실험��다.
+
+2.6.x -mm 커� 패치들
+---------------------
+Andrew Morton� �해 배�� 실험�� 커� 패치들�다. Andrew는 모든 다른
+서브시스템 커� 트리와 패치들� 가져와서 리눅스 커� 메�� 리스트로
+온 많� 패치들과 한� 묶는다. � 트리는 새로운 기능들과 패치들� 위한
+장소를 제공하는 역할� 한다. 하나� 패치가 -mm� 한�안 있으면서 그 가치가
+�명�게 �면 Andrew나 서브시스템 메�트너는 그것� 메���� �함시키기
+위하여 Linus�게 보낸다.
+
+커� 트리� �함하고 싶� 모든 새로운 패치들� Linus�게 보내지기 전�
+-mm 트리�서 테스트를 하는 것� �극 추천한다.
+
+� 커�들� 안정�게 사용할 시스템�서� 실행하는 것� �합하지 않으며
+다른 브랜치들� 어떤 것들보다 위험하다.
+
+여러분� 커� 개발 프로세스를 �길 �한다면 � 커� 배�들� 사용하고
+테스트한 후 어떤 문제를 발견하거나 �는 모든 것� 잘 �작한다면 리눅스
+커� 메�� 리스트로 피드백� 해달�.

+ - 여러분� 패치가 아무 질문 없� 받아들여지기를 기대하는 것
+ - 방어�� �는 것
+ - �견� 무시하는 것

+
+
+커� 커뮤니티와 기업 조�간� 차��
+-----------------------------------------------------------------
+커� 커뮤니티는 가장 전통�� 회사� 개발 환경과는 다르다. 여기� 여러분들�
+문제를 피하기 위한 목�� 있다.
+  여러분들� 제안한 변경들� 관하여 �할 때 좋� 것들 :
+    - " �것� 여러 문제들� 해겹합니다."
+    - "�것� 2000 ��� 코드를 제거합니다."
+    - "�것� 내가 �하려는 것� 관해 설명하는 패치입니다."
+    - "나는 5개� 다른 아키���서 그것� 테스트했슴으로..."
+    - "여기� �련� 작� 패치들� 있습�로..."
+    - "�것� �반�� 머신�서 성능� 향�시키므로..."
+
+  여러분들� �할 때 피해야 할 좋지 않� 것들 :
+    - "우리를 그것� AIT/ptx/Solaris�서 �러한 방법으로 했다. 그러므로 그것� 좋� 것임� 틀립없다..."
+    - "나는 20년�안 �것� 해왔다. 그러므로..."
+    - "�것� �� 벌기위해 나� 회사가 필요로 하는 것�다."
+    - "�것� 우리� 엔터프��즈 �품 ��� 위한 것�다."
+    - "여기� 나� ��� �하고 있는 1000 페�지 설계 문서가 있다."
+    - "나는 6달�안 �것� 했으니..."
+    - "여기세 5000�� 짜리 패치가 있으니..."
+    - "나는 현재 뒤죽박죽� 것� 재작성했다. 그리고 여기�..."
+    - "나는 마�시한� 가지고 있으므로 � 패치는 지금 �용� 필요가 있다."
+
+커� 커뮤니티가 전통�� 소프트웨어 엔지니어� 개발 환경들과
+� 다른 �� 얼굴� 보지 않고 �한다는 ��다. �메�과 irc를 대화�
+주요수단으로 사용하는 것� 한가지 장�� 성별�나 �종� 차별�
+없다는 것�다. 리눅스 커�� 작업 환경�서는 단지 �메� 주소만
+알수 있기 때문� 여성과 소수 민족들� 모� 받아들여진다. 국제�으로
+�하게 �는 측면� 사람� �름� 근거하여 성별� 추측할 수 없게
+하기때문�  차별� 없애는 � �움� 준다. Andrea�는 �름� 가진 남�와
+Pat��는 �름� 가진 여�가 있� 수� 있는 것�다. 리눅스 커��서
+작업하며 ��� 표현해왔� 대부분� 여성들� �정�� 경험� 가지고
+있다.
+
+언어 장벽� �어� �숙하지 않� 몇몇 사람들�게 문제가 � 수� 있다.
+ 언어� 훌륭한 구사는 메�� 리스트�서 올바르게 �신� ���
+표현하기 위하여 필요하다. 그래서 여러분� �메�� 보내기 전�
+�어를 올바르게 사용하고 있는지를 체�하는 것� 바람�하다.
+
+
+여러분� 변경� 나누어�
+------------------------
+
+리눅스 커� 커뮤니티는 한꺼번� 굉장히 � 코드� 묶�� 쉽게
+받아들�지 않는다. 변경� �절하게 소개�고, 검토�고, ���
+부분으로 작게 나누어져야 한다. �것� 회사�서 하는 것과는 정확히
+반대�는 것�다. 여러분들� 제안� 개발 초기� ��� 소개�야 한다.
+그래서 여러분들� �신� 하고 있는 것� 관하여 피드백� 받� 수 있게
+�다. 커뮤니티가 여러분들� 커뮤니티와 함께 �하고 있다는 것�
+���� 만들고 커뮤니티가 여러분� 기능� 위한 쓰레기 장으로서
+사용�지 않고 있다는 것� ��게 하�. 그러나 메�� 리스트� 한번�
+50개� �메�� 보내지는 �아�. 여러분들� �련� 패치들� 항�
+� 작아야 한다.
+
+패치를 나누는 �유는 다�과 같다.
+
+1) 작� 패치들� 여러분� 패치들� �용� 수 있는 확률� 높여준다.
+   왜�하면 다른 사람들� 정확성� 검�하기 위하여 많� 시간과 노력�
+   들�기를 �하지 않는다. 5줄� 패치는 메�트너가 거� 몇 초간 ��
+   보면 �용� 수 있다. 그러나 500 줄� 패치는 정확성� 검토하기 위하여
+   몇시간� 걸릴 수� 있다(걸리는 시간� 패치� �기 혹� 다른 것�
+   비례하여 기하급수�으로 늘어난다).
+
+   패치를 작게 만드는 것� 무엇�가 잘못�었� 때 디버그하는 것�
+   쉽게 만든다. 즉, 그렇게 만드는 것� 매우 � 패치를 �용한 후�
+   조사하는 것 보다 작� 패치를 �용한 후� (그리고 몇몇� 것�
+   깨졌� 때) 하나씩 패치들� 제거해가며 디버그 하기 쉽�� 만들어 준다.
+
+2) 작� 패치들� 보내는 것�만 아니� 패치들� 제출하기전� 재작성하고
+   간단하게(혹� 간단한게 재배치하여) 하는 것� 중요하다.
+
+여기� 커� 개발� Al Viro� �야기가 있다.
+    "학�� 수학 숙제를 채�하는 선�님� ��해보�. 선�님� 학�들�
+    답� 얻�때까지 겪� 시행착오를 보길 �하지 않는다. 선�님들�
+    간결하고 가장 뛰어난 답� 보길 �한다. 훌륭한 학�� �것� 알고
+    마지막으로 답� 얻기 전 중간 과정들� 제출하진 않는다.
+
+    커� 개발� 마찬가지�다. 메�트너들과 검토하는 사람들� 문제를
+    풀어나가는 과정�� 숨겨진 과정� 보길 �하진 않는다. 그들�
+    간결하고 멋진 답� 보길 �한다."
+
+커뮤니티와 함께 �하며 뛰어난 답� 찾고 여러분들� 완성�지 않� �들
+사�� 균형� 유지해야 하는 어려움� 있� 수 있다. 그러므로 프로세스�

+여러분들� 변경들� 작� 묶�으로 유지해서 심지어는 여러분� 작업�
+모든 부분� 지금� �함� 준비가 �어있지 않지만 작� 부분� �미
+받아들여질 수 있�� 유지하는 것� 바람�하다.
+

+패치들� 받아들여지지 않� 것��는 �� 유�하�.
+
+변경� 정당화해�
+-----------------
+
+여러분들� 나누어진 패치들� 리눅스 커뮤니티가 왜 반�해야 하는지를
+알�� 하는 것� 매우 중요하다. 새로운 기능들� 필요하고 유용하다는
+것� 반드시 그� 맞는 �유가 있어야 한다.
+
+
+변경� 문서화해�
+-----------------
+
+여러분� 패치를 보내려 할때는 여러분� 무엇� �하려고 하는지를 충분히
+��하여 �메�� 작성해야 한다. � 정보는 패치를 위한 ChangeLog가 �
+것�다. 그리고 항� 그 내용� 보길 �하는 모든 사람들� 위해 보존�
+것�다. 패치는 완벽하게 다�과 같� 내용들� �함하여 설명해야 한다.
+  - 변경� 왜 필요한지

-4. subsystems
-
-4.1 Description
-
-A subsystem represents a significant entity of code that maintains an
-arbitrary number of sets of objects of various types. Since the number
-of ksets and the type of objects they contain are variable, a
-generic representation of a subsystem is minimal. 
-
-
-struct subsystem {
-	struct kset		kset;
-	struct rw_semaphore	rwsem;
-};
-
-int subsystem_register(struct subsystem *);
-void subsystem_unregister(struct subsystem *);
-
-struct subsystem * subsys_get(struct subsystem * s);
-void subsys_put(struct subsystem * s);
-
-
-A subsystem contains an embedded kset so:
-
-- It can be represented in the object hierarchy via the kset's
-  embedded kobject. 
-
-- It can maintain a default list of objects of one type. 
-
-Additional ksets may attach to the subsystem simply by referencing the
-subsystem before they are registered. (This one-way reference means
-that there is no way to determine the ksets that are attached to the
-subsystem.) 
-
-All ksets that are attached to a subsystem share the subsystem's R/W
-semaphore. 
-
-
-4.2 subsystem Programming Interface.
-
-The subsystem programming interface is simple and does not offer the
-flexibility that the kset and kobject programming interfaces do. They
-may be registered and unregistered, as well as reference counted. Each
-call forwards the calls to their embedded ksets (which forward the
-calls to their embedded kobjects).
-
-
-4.3 Helpers
-
-A number of macros are available to make dealing with subsystems and
-their embedded objects easier. 
-
-
-decl_subsys(name,type)
-
-Declares a subsystem named '<name>_subsys', with an embedded kset of
-type <type>. For example, 
-
-decl_subsys(devices,&ktype_devices);
-
-is equivalent to doing:
-
-struct subsystem device_subsys = {
-       .kset = {
-	     .kobj = {
-		   .name = "devices",
-	     },
-	     .ktype = &ktype_devices,

-The objects that are registered with a subsystem that use the
-subsystem's default list must have their kset ptr set properly. These
-objects may have embedded kobjects, ksets, or other subsystems. The
-following helpers make setting the kset easier: 
-
-
-kobj_set_kset_s(obj,subsys)
-
-- Assumes that obj->kobj exists, and is a struct kobject. 
-- Sets the kset of that kobject to the subsystem's embedded kset.
-
-
-kset_set_kset_s(obj,subsys)
-
-- Assumes that obj->kset exists, and is a struct kset.
-- Sets the kset of the embedded kobject to the subsystem's 
-  embedded kset. 
-
-subsys_set_kset(obj,subsys)
-
-- Assumes obj->subsys exists, and is a struct subsystem.
-- Sets obj->subsys.kset.kobj.kset to the subsystem's embedded kset.
-
-
-4.4 sysfs
-
-subsystems are represented in sysfs via their embedded kobjects. They
-follow the same rules as previously mentioned with no exceptions. They
-typically receive a top-level directory in sysfs, except when their
-embedded kobject is part of another kset, or the parent of the
-embedded kobject is explicitly set. 
-
-Note that the subsystem's embedded kset must be 'attached' to the
-subsystem itself in order to use its rwsem. This is done after
-kset_add() has been called. (Not before, because kset_add() uses its
-subsystem for a default parent if it doesn't already have one).

+Rusty's Remarkably Unreliable Guide to Lguest
+	- or, A Young Coder's Illustrated Hypervisor
+http://lguest.ozlabs.org
+
+Lguest is designed to be a minimal hypervisor for the Linux kernel, for
+Linux developers and users to experiment with virtualization with the
+minimum of complexity.  Nonetheless, it should have sufficient
+features to make it useful for specific tasks, and, of course, you are
+encouraged to fork and enhance it.
+
+Features:
+
+- Kernel module which runs in a normal kernel.
+- Simple I/O model for communication.
+- Simple program to create new guests.
+- Logo contains cute puppies: http://lguest.ozlabs.org
+
+Developer features:
+
+- Fun to hack on.
+- No ABI: being tied to a specific kernel anyway, you can change anything.
+- Many opportunities for improvement or feature implementation.
+
+Running Lguest:
+
+- Lguest runs the same kernel as guest and host.  You can configure
+  them differently, but usually it's easiest not to.
+
+  You will need to configure your kernel with the following options:
+
+  CONFIG_HIGHMEM64G=n ("High Memory Support" "64GB")[1]
+  CONFIG_TUN=y/m ("Universal TUN/TAP device driver support")
+  CONFIG_EXPERIMENTAL=y ("Prompt for development and/or incomplete code/drivers")
+  CONFIG_PARAVIRT=y ("Paravirtualization support (EXPERIMENTAL)")
+  CONFIG_LGUEST=y/m ("Linux hypervisor example code")
+
+  and I recommend:
+  CONFIG_HZ=100 ("Timer frequency")[2]
+
+- A tool called "lguest" is available in this directory: type "make"
+  to build it.  If you didn't build your kernel in-tree, use "make
+  O=<builddir>".
+
+- Create or find a root disk image.  There are several useful ones
+  around, such as the xm-test tiny root image at
+	  http://xm-test.xensource.com/ramdisks/initrd-1.1-i386.img
+
+  For more serious work, I usually use a distribution ISO image and
+  install it under qemu, then make multiple copies:
+
+	  dd if=/dev/zero of=rootfile bs=1M count=2048
+	  qemu -cdrom image.iso -hda rootfile -net user -net nic -boot d
+
+- "modprobe lg" if you built it as a module.
+
+- Run an lguest as root:
+
+      Documentation/lguest/lguest 64m vmlinux --tunnet=192.168.19.1 --block=rootfile root=/dev/lgba
+
+   Explanation:
+    64m: the amount of memory to use.
+
+    vmlinux: the kernel image found in the top of your build directory.  You
+       can also use a standard bzImage.
+
+    --tunnet=192.168.19.1: configures a "tap" device for networking with this
+       IP address.
+
+    --block=rootfile: a file or block device which becomes /dev/lgba
+       inside the guest.
+
+    root=/dev/lgba: this (and anything else on the command line) are
+       kernel boot parameters.
+
+- Configuring networking.  I usually have the host masquerade, using
+  "iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE" and "echo 1 >
+  /proc/sys/net/ipv4/ip_forward".  In this example, I would configure
+  eth0 inside the guest at 192.168.19.2.
+
+  Another method is to bridge the tap device to an external interface
+  using --tunnet=bridge:<bridgename>, and perhaps run dhcp on the guest
+  to obtain an IP address.  The bridge needs to be configured first:
+  this option simply adds the tap interface to it.
+
+  A simple example on my system:
+
+    ifconfig eth0 0.0.0.0
+    brctl addbr lg0
+    ifconfig lg0 up
+    brctl addif lg0 eth0
+    dhclient lg0
+
+  Then use --tunnet=bridge:lg0 when launching the guest.
+
+  See http://linux-net.osdl.org/index.php/Bridge for general information
+  on how to get bridging working.
+
+- You can also create an inter-guest network using
+  "--sharenet=<filename>": any two guests using the same file are on
+  the same network.  This file is created if it does not exist.
+
+Lguest I/O model:
+
+Lguest uses a simplified DMA model plus shared memory for I/O.  Guests
+can communicate with each other if they share underlying memory
+(usually by the lguest program mmaping the same file), but they can
+use any non-shared memory to communicate with the lguest process.
+
+Guests can register DMA buffers at any key (must be a valid physical
+address) using the LHCALL_BIND_DMA(key, dmabufs, num<<8|irq)
+hypercall.  "dmabufs" is the physical address of an array of "num"
+"struct lguest_dma": each contains a used_len, and an array of
+physical addresses and lengths.  When a transfer occurs, the
+"used_len" field of one of the buffers which has used_len 0 will be
+set to the length transferred and the irq will fire.
+
+Using an irq value of 0 unbinds the dma buffers.
+
+To send DMA, the LHCALL_SEND_DMA(key, dma_physaddr) hypercall is used,
+and the bytes used is written to the used_len field.  This can be 0 if
+noone else has bound a DMA buffer to that key or some other error.
+DMA buffers bound by the same guest are ignored.

+
+
+---------------
+1. Introduction
+---------------
+
+1.1 purpose of memory hotplug
+------------
+Memory Hotplug allows users to increase/decrease the amount of memory.
+Generally, there are two purposes.
+
+(A) For changing the amount of memory.
+    This is to allow a feature like capacity on demand.
+(B) For installing/removing DIMMs or NUMA-nodes physically.
+    This is to exchange DIMMs/NUMA-nodes, reduce power consumption, etc.
+
+(A) is required by highly virtualized environments and (B) is required by
+hardware which supports memory power management.
+
+Linux memory hotplug is designed for both purpose.
+
+
+1.2. Phases of memory hotplug
+---------------
+There are 2 phases in Memory Hotplug.
+  1) Physical Memory Hotplug phase
+  2) Logical Memory Hotplug phase.
+
+The First phase is to communicate hardware/firmware and make/erase
+environment for hotplugged memory. Basically, this phase is necessary
+for the purpose (B), but this is good phase for communication between
+highly virtualized environments too.
+
+When memory is hotplugged, the kernel recognizes new memory, makes new memory
+management tables, and makes sysfs files for new memory's operation.
+
+If firmware supports notification of connection of new memory to OS,
+this phase is triggered automatically. ACPI can notify this event. If not,
+"probe" operation by system administration is used instead.
+(see Section 4.).
+
+Logical Memory Hotplug phase is to change memory state into
+avaiable/unavailable for users. Amount of memory from user's view is
+changed by this phase. The kernel makes all memory in it as free pages
+when a memory range is available.
+
+In this document, this phase is described as online/offline.
+
+Logical Memory Hotplug phase is triggred by write of sysfs file by system
+administrator. For the hot-add case, it must be executed after Physical Hotplug
+phase by hand.
+(However, if you writes udev's hotplug scripts for memory hotplug, these
+ phases can be execute in seamless way.)
+
+
+1.3. Unit of Memory online/offline operation
+------------
+Memory hotplug uses SPARSEMEM memory model. SPARSEMEM divides the whole memory
+into chunks of the same size. The chunk is called a "section". The size of
+a section is architecture dependent. For example, power uses 16MiB, ia64 uses
+1GiB. The unit of online/offline operation is "one section". (see Section 3.)
+
+To determine the size of sections, please read this file:
+
+/sys/devices/system/memory/block_size_bytes
+
+This file shows the size of sections in byte.
+
+-----------------------
+2. Kernel Configuration
+-----------------------
+To use memory hotplug feature, kernel must be compiled with following
+config options.
+
+- For all memory hotplug
+    Memory model -> Sparse Memory  (CONFIG_SPARSEMEM)
+    Allow for memory hot-add       (CONFIG_MEMORY_HOTPLUG)
+
+- To enable memory removal, the followings are also necessary
+    Allow for memory hot remove    (CONFIG_MEMORY_HOTREMOVE)
+    Page Migration                 (CONFIG_MIGRATION)
+
+- For ACPI memory hotplug, the followings are also necessary
+    Memory hotplug (under ACPI Support menu) (CONFIG_ACPI_HOTPLUG_MEMORY)
+    This option can be kernel module.
+
+- As a related configuration, if your box has a feature of NUMA-node hotplug
+  via ACPI, then this option is necessary too.
+    ACPI0004,PNP0A05 and PNP0A06 Container Driver (under ACPI Support menu)
+    (CONFIG_ACPI_CONTAINER).
+    This option can be kernel module too.
+
+--------------------------------
+3 sysfs files for memory hotplug
+--------------------------------
+All sections have their device information under /sys/devices/system/memory as
+
+/sys/devices/system/memory/memoryXXX
+(XXX is section id.)
+
+Now, XXX is defined as start_address_of_section / section_size.
+
+For example, assume 1GiB section size. A device for a memory starting at
+0x100000000 is /sys/device/system/memory/memory4
+(0x100000000 / 1Gib = 4)
+This device covers address range [0x100000000 ... 0x140000000)
+
+Under each section, you can see 3 files.
+
+/sys/devices/system/memory/memoryXXX/phys_index
+/sys/devices/system/memory/memoryXXX/phys_device
+/sys/devices/system/memory/memoryXXX/state
+
+'phys_index' : read-only and contains section id, same as XXX.
+'state'      : read-write
+               at read:  contains online/offline state of memory.
+               at write: user can specify "online", "offline" command
+'phys_device': read-only: designed to show the name of physical memory device.
+               This is not well implemented now.
+
+NOTE:
+  These directories/files appear after physical memory hotplug phase.
+
+
+--------------------------------
+4. Physical memory hot-add phase
+--------------------------------
+
+4.1 Hardware(Firmware) Support
+------------
+On x86_64/ia64 platform, memory hotplug by ACPI is supported.
+
+In general, the firmware (ACPI) which supports memory hotplug defines
+memory class object of _HID "PNP0C80". When a notify is asserted to PNP0C80,
+Linux's ACPI handler does hot-add memory to the system and calls a hotplug udev
+script. This will be done automatically.
+
+But scripts for memory hotplug are not contained in generic udev package(now).
+You may have to write it by yourself or online/offline memory by hand.
+Please see "How to online memory", "How to offline memory" in this text.
+
+If firmware supports NUMA-node hotplug, and defines an object _HID "ACPI0004",
+"PNP0A05", or "PNP0A06", notification is asserted to it, and ACPI handler
+calls hotplug code for all of objects which are defined in it.
+If memory device is found, memory hotplug code will be called.
+
+
+4.2 Notify memory hot-add event by hand
+------------
+In some environments, especially virtualized environment, firmware will not
+notify memory hotplug event to the kernel. For such environment, "probe"
+interface is supported. This interface depends on CONFIG_ARCH_MEMORY_PROBE.
+
+Now, CONFIG_ARCH_MEMORY_PROBE is supported only by powerpc but it does not
+contain highly architecture codes. Please add config if you need "probe"
+interface.
+
+Probe interface is located at
+/sys/devices/system/memory/probe
+
+You can tell the physical address of new memory to the kernel by
+
+% echo start_address_of_new_memory > /sys/devices/system/memory/probe
+
+Then, [start_address_of_new_memory, start_address_of_new_memory + section_size)
+memory range is hot-added. In this case, hotplug script is not called (in
+current implementation). You'll have to online memory by yourself.
+Please see "How to online memory" in this text.
+
+
+
+------------------------------
+5. Logical Memory hot-add phase
+------------------------------
+
+5.1. State of memory
+------------
+To see (online/offline) state of memory section, read 'state' file.
+
+% cat /sys/device/system/memory/memoryXXX/state
+
+
+If the memory section is online, you'll read "online".
+If the memory section is offline, you'll read "offline".
+
+
+5.2. How to online memory
+------------
+Even if the memory is hot-added, it is not at ready-to-use state.
+For using newly added memory, you have to "online" the memory section.
+
+For onlining, you have to write "online" to the section's state file as:
+
+% echo online > /sys/devices/system/memory/memoryXXX/state
+
+After this, section memoryXXX's state will be 'online' and the amount of
+available memory will be increased.
+
+Currently, newly added memory is added as ZONE_NORMAL (for powerpc, ZONE_DMA).
+This may be changed in future.
+
+
+
+------------------------
+6. Logical memory remove
+------------------------
+
+6.1 Memory offline and ZONE_MOVABLE
+------------
+Memory offlining is more complicated than memory online. Because memory offline
+has to make the whole memory section be unused, memory offline can fail if
+the section includes memory which cannot be freed.
+
+In general, memory offline can use 2 techniques.
+
+(1) reclaim and free all memory in the section.
+(2) migrate all pages in the section.
+
+In the current implementation, Linux's memory offline uses method (2), freeing
+all  pages in the section by page migration. But not all pages are
+migratable. Under current Linux, migratable pages are anonymous pages and
+page caches. For offlining a section by migration, the kernel has to guarantee
+that the section contains only migratable pages.
+
+Now, a boot option for making a section which consists of migratable pages is
+supported. By specifying "kernelcore=" or "movablecore=" boot option, you can
+create ZONE_MOVABLE...a zone which is just used for movable pages.
+(See also Documentation/kernel-parameters.txt)
+
+Assume the system has "TOTAL" amount of memory at boot time, this boot option
+creates ZONE_MOVABLE as following.
+
+1) When kernelcore=YYYY boot option is used,
+  Size of memory not for movable pages (not for offline) is YYYY.
+  Size of memory for movable pages (for offline) is TOTAL-YYYY.
+
+2) When movablecore=ZZZZ boot option is used,
+  Size of memory not for movable pages (not for offline) is TOTAL - ZZZZ.
+  Size of memory for movable pages (for offline) is ZZZZ.
+
+
+Note) Unfortunately, there is no information to show which section belongs
+to ZONE_MOVABLE. This is TBD.
+
+
+6.2. How to offline memory
+------------
+You can offline a section by using the same sysfs interface that was used in
+memory onlining.
+
+% echo offline > /sys/devices/system/memory/memoryXXX/state
+
+If offline succeeds, the state of the memory section is changed to be "offline".
+If it fails, some error core (like -EBUSY) will be returned by the kernel.
+Even if a section does not belong to ZONE_MOVABLE, you can try to offline it.
+If it doesn't contain 'unmovable' memory, you'll get success.
+
+A section under ZONE_MOVABLE is considered to be able to be offlined easily.
+But under some busy state, it may return -EBUSY. Even if a memory section
+cannot be offlined due to -EBUSY, you can retry offlining it and may be able to
+offline it (or not).
+(For example, a page is referred to by some kernel internal call and released
+ soon.)
+
+Consideration:
+Memory hotplug's design direction is to make the possibility of memory offlining
+higher and to guarantee unplugging memory under any situation. But it needs
+more work. Returning -EBUSY under some situation may be good because the user
+can decide to retry more or not by himself. Currently, memory offlining code
+does some amount of retry with 120 seconds timeout.
+
+-------------------------
+7. Physical memory remove
+-------------------------
+Need more implementation yet....
+ - Notification completion of remove works by OS to firmware.
+ - Guard from remove if not yet.
+
+--------------
+8. Future Work
+--------------
+  - allowing memory hot-add to ZONE_MOVABLE. maybe we need some switch like
+    sysctl or new control file.
+  - showing memory section and physical device relationship.
+  - showing memory section and node relationship (maybe good for NUMA)
+  - showing memory section is under ZONE_MOVABLE or not
+  - test and make it better memory offlining.
+  - support HugeTLB page migration and offlining.
+  - memmap removing at memory offline.
+  - physical remove memory.

+Suspend notifiers
+	(C) 2007 Rafael J. Wysocki <rjw@sisk.pl>, GPL
+
+There are some operations that device drivers may want to carry out in their
+.suspend() routines, but shouldn't, because they can cause the hibernation or
+suspend to fail. For example, a driver may want to allocate a substantial amount
+of memory (like 50 MB) in .suspend(), but that shouldn't be done after the
+swsusp's memory shrinker has run.
+
+Also, there may be some operations, that subsystems want to carry out before a
+hibernation/suspend or after a restore/resume, requiring the system to be fully
+functional, so the drivers' .suspend() and .resume() routines are not suitable
+for this purpose.  For example, device drivers may want to upload firmware to
+their devices after a restore from a hibernation image, but they cannot do it by
+calling request_firmware() from their .resume() routines (user land processes
+are frozen at this point).  The solution may be to load the firmware into
+memory before processes are frozen and upload it from there in the .resume()
+routine.  Of course, a hibernation notifier may be used for this purpose.
+
+The subsystems that have such needs can register suspend notifiers that will be
+called upon the following events by the suspend core:
+
+PM_HIBERNATION_PREPARE	The system is going to hibernate or suspend, tasks will
+			be frozen immediately.
+
+PM_POST_HIBERNATION	The system memory state has been restored from a
+			hibernation image or an error occured during the
+			hibernation.  Device drivers' .resume() callbacks have
+			been executed and tasks have been thawed.
+
+PM_SUSPEND_PREPARE	The system is preparing for a suspend.
+
+PM_POST_SUSPEND		The system has just resumed or an error occured during
+			the suspend.	Device drivers' .resume() callbacks have
+			been executed and tasks have been thawed.
+
+It is generally assumed that whatever the notifiers do for
+PM_HIBERNATION_PREPARE, should be undone for PM_POST_HIBERNATION.  Analogously,
+operations performed for PM_SUSPEND_PREPARE should be reversed for
+PM_POST_SUSPEND.  Additionally, all of the notifiers are called for
+PM_POST_HIBERNATION if one of them fails for PM_HIBERNATION_PREPARE, and
+all of the notifiers are called for PM_POST_SUSPEND if one of them fails for
+PM_SUSPEND_PREPARE.
+
+The hibernation and suspend notifiers are called with pm_mutex held.  They are
+defined in the usual way, but their last argument is meaningless (it is always
+NULL).  To register and/or unregister a suspend notifier use the functions
+register_pm_notifier() and unregister_pm_notifier(), respectively, defined in
+include/linux/suspend.h .  If you don't need to unregister the notifier, you can
+also use the pm_notifier() macro defined in include/linux/suspend.h .

+This document explains the thinking about the revamped and streamlined
+nice-levels implementation in the new Linux scheduler.
+
+Nice levels were always pretty weak under Linux and people continuously
+pestered us to make nice +19 tasks use up much less CPU time.
+
+Unfortunately that was not that easy to implement under the old
+scheduler, (otherwise we'd have done it long ago) because nice level
+support was historically coupled to timeslice length, and timeslice
+units were driven by the HZ tick, so the smallest timeslice was 1/HZ.
+
+In the O(1) scheduler (in 2003) we changed negative nice levels to be
+much stronger than they were before in 2.4 (and people were happy about
+that change), and we also intentionally calibrated the linear timeslice
+rule so that nice +19 level would be _exactly_ 1 jiffy. To better
+understand it, the timeslice graph went like this (cheesy ASCII art
+alert!):
+
+
+                   A
+             \     | [timeslice length]
+              \    |
+               \   |
+                \  |
+                 \ |
+                  \|___100msecs
+                   |^ . _
+                   |      ^ . _
+                   |            ^ . _
+ -*----------------------------------*-----> [nice level]
+ -20               |                +19
+                   |
+                   |
+
+So that if someone wanted to really renice tasks, +19 would give a much
+bigger hit than the normal linear rule would do. (The solution of
+changing the ABI to extend priorities was discarded early on.)
+
+This approach worked to some degree for some time, but later on with
+HZ=1000 it caused 1 jiffy to be 1 msec, which meant 0.1% CPU usage which
+we felt to be a bit excessive. Excessive _not_ because it's too small of
+a CPU utilization, but because it causes too frequent (once per
+millisec) rescheduling. (and would thus trash the cache, etc. Remember,
+this was long ago when hardware was weaker and caches were smaller, and
+people were running number crunching apps at nice +19.)
+
+So for HZ=1000 we changed nice +19 to 5msecs, because that felt like the
+right minimal granularity - and this translates to 5% CPU utilization.
+But the fundamental HZ-sensitive property for nice+19 still remained,
+and we never got a single complaint about nice +19 being too _weak_ in
+terms of CPU utilization, we only got complaints about it (still) being
+too _strong_ :-)
+
+To sum it up: we always wanted to make nice levels more consistent, but
+within the constraints of HZ and jiffies and their nasty design level
+coupling to timeslices and granularity it was not really viable.
+
+The second (less frequent but still periodically occuring) complaint
+about Linux's nice level support was its assymetry around the origo
+(which you can see demonstrated in the picture above), or more
+accurately: the fact that nice level behavior depended on the _absolute_
+nice level as well, while the nice API itself is fundamentally
+"relative":
+
+   int nice(int inc);
+
+   asmlinkage long sys_nice(int increment)
+
+(the first one is the glibc API, the second one is the syscall API.)
+Note that the 'inc' is relative to the current nice level. Tools like
+bash's "nice" command mirror this relative API.
+
+With the old scheduler, if you for example started a niced task with +1
+and another task with +2, the CPU split between the two tasks would
+depend on the nice level of the parent shell - if it was at nice -10 the
+CPU split was different than if it was at +5 or +10.
+
+A third complaint against Linux's nice level support was that negative
+nice levels were not 'punchy enough', so lots of people had to resort to
+run audio (and other multimedia) apps under RT priorities such as
+SCHED_FIFO. But this caused other problems: SCHED_FIFO is not starvation
+proof, and a buggy SCHED_FIFO app can also lock up the system for good.
+
+The new scheduler in v2.6.23 addresses all three types of complaints:
+
+To address the first complaint (of nice levels being not "punchy"
+enough), the scheduler was decoupled from 'time slice' and HZ concepts
+(and granularity was made a separate concept from nice levels) and thus
+it was possible to implement better and more consistent nice +19
+support: with the new scheduler nice +19 tasks get a HZ-independent
+1.5%, instead of the variable 3%-5%-9% range they got in the old
+scheduler.
+
+To address the second complaint (of nice levels not being consistent),
+the new scheduler makes nice(1) have the same CPU utilization effect on
+tasks, regardless of their absolute nice levels. So on the new
+scheduler, running a nice +10 and a nice 11 task has the same CPU
+utilization "split" between them as running a nice -5 and a nice -4
+task. (one will get 55% of the CPU, the other 45%.) That is why nice
+levels were changed to be "multiplicative" (or exponential) - that way
+it does not matter which nice level you start out from, the 'relative
+result' will always be the same.
+
+The third complaint (of negative nice levels not being "punchy" enough
+and forcing audio apps to run under the more dangerous SCHED_FIFO
+scheduling policy) is addressed by the new scheduler almost
+automatically: stronger negative nice levels are an automatic
+side-effect of the recalibrated dynamic range of nice levels.

+    On some hardwares, you may need to add a proper probe_mask option
+    to avoid the "azx_get_response timeout" problem above, instead.
+    This occurs when the access to non-existing or non-working codec slot
+    (likely a modem one) causes a stall of the communication via HD-audio
+    bus.  You can see which codec slots are probed by enabling
+    CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
+    proc files.  Then limit the slots to probe by probe_mask option.
+    For example, probe_mask=1 means to probe only the first slot, and
+    probe_mask=4 means only the third slot.

+3 - Audiophile USB Audio support in ALSA
+========================================
 
 Audio functions of the Audiophile USB device are handled by the snd-usb-audio 
 module. This module can work in a default mode (without any device-specific 
 parameter), or in an "advanced" mode with the device-specific parameter called 
 "device_setup".
 
-2.2.1 - Default Alsa driver mode
-
-The default behavior of the snd-usb-audio driver is to parse the device 
-capabilities at startup and enable all functions inside the device (including 
-all ports at any supported sample rates and sample depths). This approach 
-has the advantage to let the driver easily switch from sample rates/depths 
-automatically according to the need of the application claiming the device.
-
-In this case the Audiophile ports are mapped to alsa pcm devices in the 
-following way (I suppose the device's index is 1):
+3.1 - Default Alsa driver mode
+------------------------------
+
+The default behavior of the snd-usb-audio driver is to list the device 
+capabilities at startup and activate the required mode when required 
+by the applications: for instance if the user is recording in a 
+24bit-depth-mode and immediately after wants to switch to a 16bit-depth mode,
+the snd-usb-audio module will reconfigure the device on the fly.
+
+This approach has the advantage to let the driver automatically switch from sample 
+rates/depths automatically according to the user's needs. However, those who 
+are using the device under windows know that this is not how the device is meant to
+work: under windows applications must be closed before using the m-audio control
+panel to switch the device working mode. Thus as we'll see in next section, this

+In this modes the device operates only at 16bits-modes. Before kernel 2.6.23,

+
+Thanks to Hakan Lennestal (who discovered the Little-Endiannes of the device in
+these modes) a fix has been committed (expected in kernel 2.6.23) and
+Alsa now reports Little-Endian interfaces. Thus playing a file now is as simple as

+
  * Or while configuring the modules options in your modules configuration file

        alias snd-card-1 snd-usb-audio
        options snd-usb-audio index=1 device_setup=0x09
 
-IMPORTANT NOTE WHEN SWITCHING CONFIGURATION:
--------------------------------------------
- * You may need to _first_ initialize the module with the correct device_setup 
-   parameter and _only_after_ turn on the Audiophile USB device
- * This is especially true when switching the sample depth:
+CAUTION when initializaing the device
+-------------------------------------
+
+ * Correct initialization on the device requires that device_setup is given to
+   the module BEFORE the device is turned on. So, if you use the "manual probing"
+   method described above, take care to power-on the device AFTER this initialization.
+
+ * Failing to respect this will lead in a misconfiguration of the device. In this case
+   turn off the device, unproble the snd-usb-audio module, then probe it again with 
+   correct device_setup parameter and then (and only then) turn on the device again.
+
+ * If you've correctly initialized the device in a valid mode and then want to switch
+   to  another mode (possibly with another sample-depth), please use also the following 
+   procedure:
    - first turn off the device
    - de-register the snd-usb-audio module (modprobe -r)
    - change the device_setup parameter by changing the device_setup
      option in /etc/modprobe.conf 
    - turn on the device
+ * A workaround for this last issue has been applied to kernel 2.6.23, but it may not
+   be enough to ensure the 'stability' of the device initialization.

-3 - Audiophile USB and Jack support
+4 - Audiophile USB and Jack support
 ===================================
 
 This section deals with support of the Audiophile USB device in Jack.
-The main issue regarding this support is that the device is Big Endian 
-compliant.
 
-3.1 - Using the plug alsa plugin
---------------------------------
+There are 2 main potential issues when using Jackd with the device:
+* support for Big-Endian devices in 24-bit modes
+* support for 4-in / 4-out channels
+
+4.1 - Direct support in Jackd
+-----------------------------
 
-Jack doesn't directly support big endian devices. Thus, one way to have support 
-for this device with Alsa is to use the Alsa "plug" converter.
+Jack supports big endian devices only in recent versions (thanks to
+Andreas Steinmetz for his first big-endian patch). I can't remember 
+extacly when this support was released into jackd, let's just say that 
+with jackd version 0.103.0 it's almost ok (just a small bug is affecting 
+16bits Big-Endian devices, but since you've read  carefully the above 
+paragraphs, you're now using kernel >= 2.6.23 and your 16bits devices 
+are now Little Endians ;-) ).
+
+You can run jackd with the following command for playback with Ao and
+record with Ai:
+  % jackd -R -dalsa -Phw:1,0 -r48000 -p128 -n2 -D -Chw:1,1
+
+4.2 - Using Alsa plughw
+-----------------------
+If you don't have a recent Jackd installed, you can downgrade to using
+the Alsa "plug" converter.
 
 For instance here is one way to run Jack with 2 playback channels on Ao and 2 
 capture channels from Ai:
   % jackd -R -dalsa -dplughw:1 -r48000 -p256 -n2 -D -Cplughw:1,1
 
-
 However you may see the following warning message:
 "You appear to be using the ALSA software "plug" layer, probably a result of 
 using the "default" ALSA device. This is less efficient than it could be. 
 Consider using a hardware device instead rather than using the plug layer."
 
-3.2 - Patching alsa to use direct pcm device

-A patch for Jack by Andreas Steinmetz adds support for Big Endian devices. 
-However it has not been included in the CVS tree.

-You can find it at the following URL:
-http://sourceforge.net/tracker/index.php?func=detail&aid=1289682&group_id=39687&

 Hot keys

 procfs: /proc/acpi/ibm/hotkey

-Without this driver, only the Fn-F4 key (sleep button) generates an
-ACPI event. With the driver loaded, the hotkey feature enabled and the
-mask set (see below), the various hot keys generate ACPI events in the
+In a ThinkPad, the ACPI HKEY handler is responsible for comunicating
+some important events and also keyboard hot key presses to the operating
+system.  Enabling the hotkey functionality of thinkpad-acpi signals the
+firmware that such a driver is present, and modifies how the ThinkPad
+firmware will behave in many situations.
+
+When the hotkey feature is enabled and the hot key mask is set (see
+below), the various hot keys either generate ACPI events in the
 following format:
 
 	ibm/hotkey HKEY 00000080 0000xxxx
 
-The last four digits vary depending on the key combination pressed.
-All labeled Fn-Fx key combinations generate distinct events. In
-addition, the lid microswitch and some docking station buttons may
-also generate such events.
-
-The bit mask allows some control over which hot keys generate ACPI
-events. Not all bits in the mask can be modified. Not all bits that
-can be modified do anything. Not all hot keys can be individually
-controlled by the mask. Most recent ThinkPad models honor the
-following bits (assuming the hot keys feature has been enabled):
-
-	key	bit	behavior when set	behavior when unset
-
-	Fn-F3			always generates ACPI event
-	Fn-F4			always generates ACPI event
-	Fn-F5	0010	generate ACPI event	enable/disable Bluetooth
-	Fn-F7	0040	generate ACPI event	switch LCD and external display
-	Fn-F8	0080	generate ACPI event	expand screen or none
-	Fn-F9	0100	generate ACPI event	none
-	Fn-F12			always generates ACPI event
-
-Some models do not support all of the above. For example, the T30 does
-not support Fn-F5 and Fn-F9. Other models do not support the mask at
-all. On those models, hot keys cannot be controlled individually.
-
-Note that enabling ACPI events for some keys prevents their default
-behavior. For example, if events for Fn-F5 are enabled, that key will
-no longer enable/disable Bluetooth by itself. This can still be done
-from an acpid handler for the ibm/hotkey event.
-
-Note also that not all Fn key combinations are supported through
-ACPI. For example, on the X40, the brightness, volume and "Access IBM"
-buttons do not generate ACPI events even with this driver. They *can*
-be used through the "ThinkPad Buttons" utility, see
-http://www.nongnu.org/tpb/
+or events over the input layer.  The input layer support accepts the
+standard IOCTLs to remap the keycodes assigned to each hotkey.
+
+When the input device is open, the driver will suppress any ACPI hot key
+events that get translated into a meaningful input layer event, in order
+to avoid sending duplicate events to userspace.  Hot keys that are
+mapped to KEY_RESERVED in the keymap are not translated, and will always
+generate an ACPI ibm/hotkey HKEY event, and no input layer events.
+
+The hot key bit mask allows some control over which hot keys generate
+events.  If a key is "masked" (bit set to 0 in the mask), the firmware
+will handle it.  If it is "unmasked", it signals the firmware that
+thinkpad-acpi would prefer to handle it, if the firmware would be so
+kind to allow it (and it often doesn't!).
+
+Not all bits in the mask can be modified.  Not all bits that can be
+modified do anything.  Not all hot keys can be individually controlled
+by the mask.  Some models do not support the mask at all, and in those
+models, hot keys cannot be controlled individually.  The behaviour of
+the mask is, therefore, higly dependent on the ThinkPad model.
+
+Note that unmasking some keys prevents their default behavior.  For
+example, if Fn+F5 is unmasked, that key will no longer enable/disable
+Bluetooth by itself.
+
+Note also that not all Fn key combinations are supported through ACPI.
+For example, on the X40, the brightness, volume and "Access IBM" buttons

-Time Interpolators
-------------------
-
-Time interpolators are a base of time calculation between timer ticks and
-allow an accurate determination of time down to the accuracy of the time
-source in nanoseconds.
-
-The architecture specific code typically provides gettimeofday and
-settimeofday under Linux. The time interpolator provides both if an arch
-defines CONFIG_TIME_INTERPOLATION. The arch still must set up timer tick
-operations and call the necessary functions to advance the clock.
-
-With the time interpolator a standardized interface exists for time
-interpolation between ticks. The provided logic is highly scalable
-and has been tested in SMP situations of up to 512 CPUs.
-
-If CONFIG_TIME_INTERPOLATION is defined then the architecture specific code
-(or the device drivers - like HPET) may register time interpolators.
-These are typically defined in the following way:
-
-static struct time_interpolator my_interpolator {
-	.frequency = MY_FREQUENCY,
-	.source = TIME_SOURCE_MMIO32,
-	.shift = 8,		/* scaling for higher accuracy */
-	.drift = -1,		/* Unknown drift */
-	.jitter = 0		/* time source is stable */
-};
-
-void time_init(void)
-{
-	....
-	/* Initialization of the timer *.
-	my_interpolator.address = &my_timer;
-	register_time_interpolator(&my_interpolator);
-	....
-}

+What is Linux Memory Policy?
+
+In the Linux kernel, "memory policy" determines from which node the kernel will
+allocate memory in a NUMA system or in an emulated NUMA system.  Linux has
+supported platforms with Non-Uniform Memory Access architectures since 2.4.?.
+The current memory policy support was added to Linux 2.6 around May 2004.  This
+document attempts to describe the concepts and APIs of the 2.6 memory policy
+support.
+
+Memory policies should not be confused with cpusets (Documentation/cpusets.txt)
+which is an administrative mechanism for restricting the nodes from which
+memory may be allocated by a set of processes. Memory policies are a
+programming interface that a NUMA-aware application can take advantage of.  When
+both cpusets and policies are applied to a task, the restrictions of the cpuset
+takes priority.  See "MEMORY POLICIES AND CPUSETS" below for more details.
+
+MEMORY POLICY CONCEPTS
+
+Scope of Memory Policies
+
+The Linux kernel supports _scopes_ of memory policy, described here from
+most general to most specific:
+
+    System Default Policy:  this policy is "hard coded" into the kernel.  It
+    is the policy that governs all page allocations that aren't controlled
+    by one of the more specific policy scopes discussed below.  When the
+    system is "up and running", the system default policy will use "local
+    allocation" described below.  However, during boot up, the system
+    default policy will be set to interleave allocations across all nodes
+    with "sufficient" memory, so as not to overload the initial boot node
+    with boot-time allocations.
+
+    Task/Process Policy:  this is an optional, per-task policy.  When defined
+    for a specific task, this policy controls all page allocations made by or
+    on behalf of the task that aren't controlled by a more specific scope.
+    If a task does not define a task policy, then all page allocations that
+    would have been controlled by the task policy "fall back" to the System
+    Default Policy.
+
+	The task policy applies to the entire address space of a task. Thus,
+	it is inheritable, and indeed is inherited, across both fork()
+	[clone() w/o the CLONE_VM flag] and exec*().  This allows a parent task
+	to establish the task policy for a child task exec()'d from an
+	executable image that has no awareness of memory policy.  See the
+	MEMORY POLICY APIS section, below, for an overview of the system call
+	that a task may use to set/change it's task/process policy.
+
+	In a multi-threaded task, task policies apply only to the thread
+	[Linux kernel task] that installs the policy and any threads
+	subsequently created by that thread.  Any sibling threads existing
+	at the time a new task policy is installed retain their current
+	policy.
+
+	A task policy applies only to pages allocated after the policy is
+	installed.  Any pages already faulted in by the task when the task
+	changes its task policy remain where they were allocated based on
+	the policy at the time they were allocated.
+
+    VMA Policy:  A "VMA" or "Virtual Memory Area" refers to a range of a task's
+    virtual adddress space.  A task may define a specific policy for a range
+    of its virtual address space.   See the MEMORY POLICIES APIS section,
+    below, for an overview of the mbind() system call used to set a VMA
+    policy.
+
+    A VMA policy will govern the allocation of pages that back this region of
+    the address space.  Any regions of the task's address space that don't
+    have an explicit VMA policy will fall back to the task policy, which may
+    itself fall back to the System Default Policy.
+
+    VMA policies have a few complicating details:
+
+	VMA policy applies ONLY to anonymous pages.  These include pages
+	allocated for anonymous segments, such as the task stack and heap, and
+	any regions of the address space mmap()ed with the MAP_ANONYMOUS flag.
+	If a VMA policy is applied to a file mapping, it will be ignored if
+	the mapping used the MAP_SHARED flag.  If the file mapping used the
+	MAP_PRIVATE flag, the VMA policy will only be applied when an
+	anonymous page is allocated on an attempt to write to the mapping--
+	i.e., at Copy-On-Write.
+
+	VMA policies are shared between all tasks that share a virtual address
+	space--a.k.a. threads--independent of when the policy is installed; and
+	they are inherited across fork().  However, because VMA policies refer
+	to a specific region of a task's address space, and because the address
+	space is discarded and recreated on exec*(), VMA policies are NOT
+	inheritable across exec().  Thus, only NUMA-aware applications may
+	use VMA policies.
+
+	A task may install a new VMA policy on a sub-range of a previously
+	mmap()ed region.  When this happens, Linux splits the existing virtual
+	memory area into 2 or 3 VMAs, each with it's own policy.
+
+	By default, VMA policy applies only to pages allocated after the policy
+	is installed.  Any pages already faulted into the VMA range remain
+	where they were allocated based on the policy at the time they were
+	allocated.  However, since 2.6.16, Linux supports page migration via
+	the mbind() system call, so that page contents can be moved to match
+	a newly installed policy.
+
+    Shared Policy:  Conceptually, shared policies apply to "memory objects"
+    mapped shared into one or more tasks' distinct address spaces.  An
+    application installs a shared policies the same way as VMA policies--using
+    the mbind() system call specifying a range of virtual addresses that map
+    the shared object.  However, unlike VMA policies, which can be considered
+    to be an attribute of a range of a task's address space, shared policies
+    apply directly to the shared object.  Thus, all tasks that attach to the
+    object share the policy, and all pages allocated for the shared object,
+    by any task, will obey the shared policy.
+
+	As of 2.6.22, only shared memory segments, created by shmget() or
+	mmap(MAP_ANONYMOUS|MAP_SHARED), support shared policy.  When shared
+	policy support was added to Linux, the associated data structures were
+	added to hugetlbfs shmem segments.  At the time, hugetlbfs did not
+	support allocation at fault time--a.k.a lazy allocation--so hugetlbfs
+	shmem segments were never "hooked up" to the shared policy support.
+	Although hugetlbfs segments now support lazy allocation, their support
+	for shared policy has not been completed.
+
+	As mentioned above [re: VMA policies], allocations of page cache
+	pages for regular files mmap()ed with MAP_SHARED ignore any VMA
+	policy installed on the virtual address range backed by the shared
+	file mapping.  Rather, shared page cache pages, including pages backing
+	private mappings that have not yet been written by the task, follow
+	task policy, if any, else System Default Policy.
+
+	The shared policy infrastructure supports different policies on subset
+	ranges of the shared object.  However, Linux still splits the VMA of
+	the task that installs the policy for each range of distinct policy.
+	Thus, different tasks that attach to a shared memory segment can have
+	different VMA configurations mapping that one shared object.  This
+	can be seen by examining the /proc/<pid>/numa_maps of tasks sharing
+	a shared memory region, when one task has installed shared policy on
+	one or more ranges of the region.
+
+Components of Memory Policies
+
+    A Linux memory policy is a tuple consisting of a "mode" and an optional set
+    of nodes.  The mode determine the behavior of the policy, while the
+    optional set of nodes can be viewed as the arguments to the behavior.
+
+   Internally, memory policies are implemented by a reference counted
+   structure, struct mempolicy.  Details of this structure will be discussed
+   in context, below, as required to explain the behavior.
+
+	Note:  in some functions AND in the struct mempolicy itself, the mode
+	is called "policy".  However, to avoid confusion with the policy tuple,
+	this document will continue to use the term "mode".
+
+   Linux memory policy supports the following 4 behavioral modes:
+
+	Default Mode--MPOL_DEFAULT:  The behavior specified by this mode is
+	context or scope dependent.
+
+	    As mentioned in the Policy Scope section above, during normal
+	    system operation, the System Default Policy is hard coded to
+	    contain the Default mode.
+
+	    In this context, default mode means "local" allocation--that is
+	    attempt to allocate the page from the node associated with the cpu
+	    where the fault occurs.  If the "local" node has no memory, or the
+	    node's memory can be exhausted [no free pages available], local
+	    allocation will "fallback to"--attempt to allocate pages from--
+	    "nearby" nodes, in order of increasing "distance".
+
+		Implementation detail -- subject to change:  "Fallback" uses
+		a per node list of sibling nodes--called zonelists--built at
+		boot time, or when nodes or memory are added or removed from
+		the system [memory hotplug].  These per node zonelist are
+		constructed with nodes in order of increasing distance based
+		on information provided by the platform firmware.
+
+	    When a task/process policy or a shared policy contains the Default
+	    mode, this also means "local allocation", as described above.
+
+	    In the context of a VMA, Default mode means "fall back to task
+	    policy"--which may or may not specify Default mode.  Thus, Default
+	    mode can not be counted on to mean local allocation when used
+	    on a non-shared region of the address space.  However, see
+	    MPOL_PREFERRED below.
+
+	    The Default mode does not use the optional set of nodes.
+
+	MPOL_BIND:  This mode specifies that memory must come from the
+	set of nodes specified by the policy.
+
+	    The memory policy APIs do not specify an order in which the nodes
+	    will be searched.  However, unlike "local allocation", the Bind
+	    policy does not consider the distance between the nodes.  Rather,
+	    allocations will fallback to the nodes specified by the policy in
+	    order of numeric node id.  Like everything in Linux, this is subject
+	    to change.
+
+	MPOL_PREFERRED:  This mode specifies that the allocation should be
+	attempted from the single node specified in the policy.  If that
+	allocation fails, the kernel will search other nodes, exactly as
+	it would for a local allocation that started at the preferred node
+	in increasing distance from the preferred node.  "Local" allocation
+	policy can be viewed as a Preferred policy that starts at the node
+	containing the cpu where the allocation takes place.
+
+	    Internally, the Preferred policy uses a single node--the
+	    preferred_node member of struct mempolicy.  A "distinguished
+	    value of this preferred_node, currently '-1', is interpreted
+	    as "the node containing the cpu where the allocation takes
+	    place"--local allocation.  This is the way to specify
+	    local allocation for a specific range of addresses--i.e. for
+	    VMA policies.
+
+	MPOL_INTERLEAVED:  This mode specifies that page allocations be
+	interleaved, on a page granularity, across the nodes specified in
+	the policy.  This mode also behaves slightly differently, based on
+	the context where it is used:
+
+	    For allocation of anonymous pages and shared memory pages,
+	    Interleave mode indexes the set of nodes specified by the policy
+	    using the page offset of the faulting address into the segment
+	    [VMA] containing the address modulo the number of nodes specified
+	    by the policy.  It then attempts to allocate a page, starting at
+	    the selected node, as if the node had been specified by a Preferred
+	    policy or had been selected by a local allocation.  That is,
+	    allocation will follow the per node zonelist.
+
+	    For allocation of page cache pages, Interleave mode indexes the set
+	    of nodes specified by the policy using a node counter maintained
+	    per task.  This counter wraps around to the lowest specified node
+	    after it reaches the highest specified node.  This will tend to
+	    spread the pages out over the nodes specified by the policy based
+	    on the order in which they are allocated, rather than based on any
+	    page offset into an address range or file.  During system boot up,
+	    the temporary interleaved system default policy works in this
+	    mode.
+
+MEMORY POLICY APIs
+
+Linux supports 3 system calls for controlling memory policy.  These APIS
+always affect only the calling task, the calling task's address space, or
+some shared object mapped into the calling task's address space.
+
+	Note:  the headers that define these APIs and the parameter data types
+	for user space applications reside in a package that is not part of
+	the Linux kernel.  The kernel system call interfaces, with the 'sys_'
+	prefix, are defined in <linux/syscalls.h>; the mode and flag
+	definitions are defined in <linux/mempolicy.h>.
+
+Set [Task] Memory Policy:
+
+	long set_mempolicy(int mode, const unsigned long *nmask,
+					unsigned long maxnode);
+
+	Set's the calling task's "task/process memory policy" to mode
+	specified by the 'mode' argument and the set of nodes defined
+	by 'nmask'.  'nmask' points to a bit mask of node ids containing
+	at least 'maxnode' ids.
+
+	See the set_mempolicy(2) man page for more details
+
+
+Get [Task] Memory Policy or Related Information
+
+	long get_mempolicy(int *mode,
+			   const unsigned long *nmask, unsigned long maxnode,
+			   void *addr, int flags);
+
+	Queries the "task/process memory policy" of the calling task, or
+	the policy or location of a specified virtual address, depending
+	on the 'flags' argument.
+
+	See the get_mempolicy(2) man page for more details
+
+
+Install VMA/Shared Policy for a Range of Task's Address Space
+
+	long mbind(void *start, unsigned long len, int mode,
+		   const unsigned long *nmask, unsigned long maxnode,
+		   unsigned flags);
+
+	mbind() installs the policy specified by (mode, nmask, maxnodes) as
+	a VMA policy for the range of the calling task's address space
+	specified by the 'start' and 'len' arguments.  Additional actions

+
+MEMORY POLICY COMMAND LINE INTERFACE
+
+Although not strictly part of the Linux implementation of memory policy,
+a command line tool, numactl(8), exists that allows one to:
+
++ set the task policy for a specified program via set_mempolicy(2), fork(2) and
+  exec(2)
+
++ set the shared policy for a shared memory segment via mbind(2)
+
+The numactl(8) tool is packages with the run-time version of the library
+containing the memory policy system call wrappers.  Some distributions
+package the headers and compile-time libraries in a separate development
+package.
+
+
+MEMORY POLICIES AND CPUSETS
+
+Memory policies work within cpusets as described above.  For memory policies
+that require a node or set of nodes, the nodes are restricted to the set of
+nodes whose memories are allowed by the cpuset constraints.  If the
+intersection of the set of nodes specified for the policy and the set of nodes
+allowed by the cpuset is the empty set, the policy is considered invalid and
+cannot be installed.
+
+The interaction of memory policies and cpusets can be problematic for a
+couple of reasons:
+
+1) the memory policy APIs take physical node id's as arguments.  However, the
+   memory policy APIs do not provide a way to determine what nodes are valid
+   in the context where the application is running.  An application MAY consult
+   the cpuset file system [directly or via an out of tree, and not generally
+   available, libcpuset API] to obtain this information, but then the
+   application must be aware that it is running in a cpuset and use what are
+   intended primarily as administrative APIs.
+
+   However, as long as the policy specifies at least one node that is valid
+   in the controlling cpuset, the policy can be used.
+
+2) when tasks in two cpusets share access to a memory region, such as shared
+   memory segments created by shmget() of mmap() with the MAP_ANONYMOUS and
+   MAP_SHARED flags, and any of the tasks install shared policy on the region,
+   only nodes whose memories are allowed in both cpusets may be used in the
+   policies.  Again, obtaining this information requires "stepping outside"
+   the memory policy APIs, as well as knowing in what cpusets other task might
+   be attaching to the shared region, to use the cpuset information.
+   Furthermore, if the cpusets' allowed memory sets are disjoint, "local"
+   allocation is the only valid policy.

+如何�与Linux内核开�
+---------------------
+
+这是一篇将如何�与Linux内核开�的相关问题一网打尽的终�秘笈。它将指导你
+�为一�Linux内核开�者，并且学会如何�Linux内核开�社区�作。它尽�能�
+包括任何关于内核编程的技术细节，但会给你指引一�获得这些知识的正确途径。
+
+如果这篇文章中的任何内容��适用，请给文末列出的文件维护者��补�。
+
+
+入门
+----
+
+你想了解如何�为一�Linux内核开�者？或者����你“给这个设备写个Linux
+驱动程��？这篇文章的目的就是教会你达�这些目标的全部诀�，它将�述你需
+��过的�程以�给出如何�内核社区�作的一些�示。它还将试图解释内核社区
+为何这样�作。
+
+Linux内核大部分是由C语言写�的，一些体系结构相关的代�用到了汇编语言。�
+�与内核开�，你必须精通C语言。除�你想为�个架构开�底层代�，�则你并
+�需�了解（任何体系结构的）汇编语言。下�列举的书�虽然�能替代扎实的C
+语言教育和多年的开��验，但如果需�的�，�为�考还是�错的：
+ - "The C Programming Language" by Kernighan and Ritchie [Prentice Hall]
+   《C程�设计语言（第2版·新版）》（��文 �志 译）[机械工业出版社]
+ - "Practical C Programming" by Steve Oualline [O'Reilly]
+   《实用C语言编程（第三版）》（郭大海 译）[中国电力出版社]
+ - "C:  A Reference Manual" by Harbison and Steele [Prentice Hall]
+   《C语言�考手册（原书第5版）》（邱仲潘 等译）[机械工业出版社]
+
+Linux内核使用GNU C和GNU工具链开�。虽然它�循ISO C89标准，但也用到了一些
+标准中没有定义的扩展。内核是自给自足的C环境，��赖于标准C库的支�，所以
+并�支�C标准中的部分定义。比如long long类型的大数除法和浮点�算就��许
+使用。有时候确实很难弄清楚内核对工具链的�求和它所使用的扩展，�幸的是目
+�还没有明确的�考资料�以解释它们。请查阅gcc信�页（使用“info gcc�命令
+显示）获得一些这方�信�。
+
+请记�你是在学习怎么和已�存在的开�社区打交�。它由一群形形色色的人组�，
+他们对代��风格和过程有�很高的标准。这些标准是在长期实践中总结出�的，
+适应于地�上分散的大型开�团队。它们已�被很好得整��档，建议你在开�
+之�尽�能多的学习这些标准，而��期望别人�适应你或者你公�的行为方�。
+
+
+法律问题
+--------
+
+Linux内核�代�都是在GPL（通用公共许��）的�护下�布的。�了解这�许�
+的细节请查看�代�主目录下的COPYING文件。如果你对它还有更深入问题请�系
+律师，而��在Linux内核邮件组上�问。因为邮件组里的人并�是律师，��期
+望他们的�有法律效力。
+
+对于GPL的常�问题和解答，请访问以下链接：
+	http://www.gnu.org/licenses/gpl-faq.html
+
+
+文档
+----
+
+Linux内核代�中包�有大�的文档。这些文档对于学习如何与内核社区互动有�
+��估�的价值。当一个新的功能被加入内核，最好把解释如何使用这个功能的文
+档也放进内核。当内核的改动导致��用户空间的接��生�化时，最好将相关信
+�或手册页(manpages)的补��到mtk-manpages@gmx.net，以�手册页(manpages)
+的维护者解释这些�化。
+
+以下是内核代�中需�阅读的文档：
+  README
+    文件简�介�了Linux内核的背景，并且�述了如何�置和编译内核。内核的
+    新用户应该从这里开始。
+
+  Documentation/Changes
+    文件给出了用�编译和使用内核所需�的最�软件包列表。
+
+  Documentation/CodingStyle
+    �述Linux内核的代�风格和�由。所有新代�需��守这篇文档中定义的规
+    范。大多数维护者�会接收符�规定的补�，很多人也�会帮忙检查符�风格
+    的代�。
+
+  Documentation/SubmittingPatches
+  Documentation/SubmittingDrivers
+    这两份文档明确�述如何创建和��补�，其中包括（但�仅�于)：
+       - 邮件内容
+       - 邮件格�
+       - 选择收件人
+    �守这些规定并�能���交�功（因为所有补�需�通过严格的内容和风格
+    审查），但是忽视他们几乎就�味�失败。
+
+    其他关于如何正确地生�补�的优秀文档包括：
+    "The Perfect Patch"
+        http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt

+
+
+如何�为内核开�者
+------------------
+如果你对Linux内核开�一无所知，你应该访问“Linux内核新手�计划：
+	http://kernelnewbies.org
+它拥有一个�以问��最基本的内核开�问题的邮件列表（在�问之�一定�记得
+查找已往的邮件，确认是�有人已�回答过相�的问题）。它还拥有一个�以获得
+实时�馈的IRC�天频�，以�大�对于学习Linux内核开�相当有帮助的文档。
+
+网站简�介�了�代�组织结构��系统划分以�目�正在进行的项目（包括内核
+中的和�独维护的）。它还�供了一些基本的帮助信�，比如如何编译内核和打补
+�。
+
+如果你想加入内核开�社区并�助完�一些任务，�找�到从哪里开始，�以访问
+“Linux内核房管员�计划：
+	http://janitor.kernelnewbies.org/
+这是�佳的起点。它�供一个相对简�的任务列表，列出内核代�中需�被�新
+整�或者改正的地方。通过和负责这个计划的开�者们一�工作，你会学到将补�
+集�进内核的基本原�。如果还没有决定下一步��什么的�，你还�能会得到方
+�性的指点。
+
+如果你已�有一些现�的代�想�放到内核中，但是需�一些帮助�使它们拥有正
+确的格�。请访问“内核导师�计划。这个计划就是用�帮助你完�这个目标的。它
+是一个邮件列表，地�如下：
+	http://selenic.com/mailman/listinfo/kernel-mentors
+
+在真正动手修改内核代�之�，�解�修改的代�如何�作是必需的。�达到这个
+目的，没什么办法比直接读代�更有效了（大多数花招都会有相应的注释），而且
+一些特制的工具还�以�供帮助。例如，“Linux代�交�引用�项目就是一个值得
+特别推�的帮助工具，它将�代�显示在有编目和索引的网页上。其中一个更新�
+时的内核��库，�以通过以下地�访问：

+
+
+开��程
+--------
+
+目�Linux内核开��程包括几个“主内核分支�和很多�系统相关的内核分支。这
+些分支包括：
+  - 2.6.x主内核��树
+  - 2.6.x.y -stable内核��树
+  - 2.6.x -git内核补�集
+  - 2.6.x -mm内核补�集
+  - �系统相关的内核��树和补�集
+
+
+2.6.x内核主��树
+-----------------
+2.6.x内核是由Linus Torvalds（Linux的创造者）亲自维护的。你�以在
+kernel.org网站的pub/linux/kernel/v2.6/目录下找到它。它的开��循以下步
+骤：
+  - �当一个新版本的内核被�布，为期两周的集�窗�将被打开。在这段时间里
+    维护者�以�Linus�交大段的修改，通常这些修改已�被放到-mm内核中几个
+    星期了。�交大�修改的首选方�是使用git工具（内核的代�版本管�工具
+    ，更多的信��以在http://git.or.cz/获�），�过使用普通补�也是�以
+    的。
+  - 两个星期以�-rc1版本内核�布。之��有�包��能影�整个内核稳定性的
+    新功能的补���能被接�。请注�一个全新的驱动程�（或者文件系统）有
+    �能在-rc1�被接�是因为这样的修改完全独立，�会影�其他的代�，所以
+    没有造�内核退步的风险。在-rc1以�也�以用git�Linus�交补�，�过所
+    有的补�需��时被��到相应的公众邮件列表以�询��。
+  - 当Linus认为当�的git��树已�达到一个���全的状�足以�布供人测试
+    时，一个新的-rc版本就会被�布。计划是�周都�布新的-rc版本。
+  - 这个过程一直�续下去直到内核被认为达到足够稳定的状�，�续时间大概是
+    6个星期。
+
+关于内核�布，值得一�的是Andrew Morton在linux-kernel邮件列表中如是说：
+	“没有人知�新内核何时会被�布，因为�布是根�已知bug的情况�决定
+	的，而�是根�一个事先制定好的时间表。�
+
+
+2.6.x.y -stable（稳定版）内核��树
+-----------------------------------
+由4个数字组�的内核版本�说明此内核是-stable版本。它们包�基于2.6.x版本
+内核的相对较�且至关��的修补，这些修补针对安全性问题或者严�的内核退步。
+
+这�版本的内核适用于那些期望获得最新的稳定版内核并且�想�与测试开�版或
+者实验版的用户。
+
+如果没有2.6.x.y版本内核存在，那么最新的2.6.x版本内核就相当于是当�的稳定
+版内核。
+
+2.6.x.y版本由“稳定版��组（邮件地�<stable@kernel.org>）维护，一般隔周�
+布新版本。
+
+内核��中的Documentation/stable_kernel_rules.txt文件具体�述了�被稳定
+版内核接�的修改类型以��布的�程。
+
+
+2.6.x -git补�集
+----------------
+Linus的内核��树的�日快照，这个��树是由git工具管�的（由此得�）。这
+些补�通常�天更新以�映Linus的��树的最新状�。它们比-rc版本的内核��
+树更具试验性质，因为这个补�集是全自动生�的，没有任何人�确认其是�真正
+�全。
+
+
+2.6.x -mm补�集
+---------------
+这是由Andrew Morton维护的试验性内核补�集。Andrew将所有�系统的内核��
+和补�拼凑到一起，并且加入了大�从linux-kernel邮件列表中采集的补�。这个
+��树是新功能和补�的试炼场。当补�在-mm补�集里�明了其价值以�Andrew
+或者相应�系统的维护者会将补��给Linus以便集�进主内核��树。
+
+在将所有新补��给Linus以集�到主内核��树之�，我们�常鼓励先把这些补
+�放在-mm版内核��树中进行测试。
+
+这些内核版本�适�在需�稳定�行的系统上�行，因为�行它们比�行任何其他
+内核分支都更具有风险。
+
+如果你想为内核开�进程�供帮助，请�试并使用这些内核版本，并在
+linux-kernel邮件列表中�供�馈，告诉大家你�到了问题还是一切正常。
+
+通常-mm版补�集�光包括这些�外的试验性补�，还包括�布时-git版主��树
+中的改动。
+
+-mm版内核没有固定的�布周期，但是通常在�两个-rc版内核�布之间都会有若干
+个-mm版内核�布（一般是1至3个）。
+
+
+�系统相关内核��树和补�集
+----------------------------
+相当一部分内核�系统开�者会公开他们自己的开���树，以便其他人能了解内
+核的��领域正在�生的事情。如上所述，这些��树会被集�到-mm版本内核中。
+

+报告bug
+-------
+
+bugzilla.kernel.org是Linux内核开�者们用�跟踪内核Bug的网站。我们鼓励用

+
+
+利用bug报告
+-----------
+
+练习内核开�技能的最好办法就是修改其他人报告的bug。你�光�以帮助内核�
+得更加稳定，还�以学会如何解决实际问题从而�高自己的技能，并且让其他开�
+者感�到你的存在。修改bug是赢得其他开�者赞誉的最好办法，因为并�是很多
+人都喜欢浪费时间去修改别人报告的bug。
+
+��试修改已知的bug，请访问http://bugzilla.kernel.org网�。如果你想获得

+
+�内核社区�作
+----------------
+
+内核社区的目标就是�供尽善尽美的内核。所以当你�交补�期望被接�进内核的
+时候，它的技术价值以�其他方�都将被评审。那么你�能会得到什么呢？
+  - 批评
+  - 评论
+  - �求修改
+  - �求�明修改的必�性
+  - 沉默
+
+�记�，这些是把补�放进内核的正常情况。你必须学会��对补�的批评和评论，
+从技术层�评估它们，然��么�写你的补��么简明扼�地论�修改是�必�
+的。如果你�的邮件没有得到任何回应，请过几天��试一次，因为有时信件会湮
+没在茫茫信海中。
+
+你�应该�的事情：
+  - 期望自己的补���任何质疑就直接被接�
+  - 翻脸
+  - 忽略别人的评论
+  - 没有按照别人的�求�任何修改就�新�交
+
+在一个努力追寻最好技术方案的社区里，对于一个补�有多少好处总会有��的�
+解。你必须�抱��作的�度，愿�改�自己的观点�适应内核的风格。或者至少
+愿�去�明你的想法是有价值的。记�，犯错误是�许的，��你愿���正确的
+方案去努力。
+
+如果你的第一个补���的是一堆修改建议，这是很正常的。这并�代表你的补�
+�会被接�，也��味�有人和你作对。你�需�改正所有�出的问题然��新�
+�你的补�。
+
+内核社区和公�文化的差异
+------------------------
+
+内核社区的工作模��大多数传统公�开�队�的工作模�并�相�。下�这些例
+�，�以帮助你���些�能�生问题：
+  用这些�介�你的修改�案会有好处：
+    - 它�时解决了多个问题
+    - 它删除了2000行代�
+    - 这是补�，它已�解释了我想�说明的
+    - 我在5���的体系结构上测试过它……
+    - 这是一系列�补�用�……
+    - 这个修改�高了普通机器的性能……
+
+  应该��如下的说法：
+    - 我们在AIX/ptx/Solaris就是这么�的，所以这么�肯定是好的……
+    - 我�这行已�20年了，所以……
+    - 为了我们公�赚钱考虑必须这么�
+    - 这是我们的�业产�线所需�的
+    - 这里是�述我观点的1000页设计文档
+    - 这是一个5000行的补�用�……
+    - 我�写了现在乱七八糟的代�，这就是……
+    - 我被规定了最�期�，所以这个补�需�立刻被接�
+
+�外一个内核社区与大部分传统公�的软件开�队���的地方是无法�对�地交
+�。使用电�邮件和IRC�天工具�为主�沟通工具的一个好处是性别和��歧视
+将会更少。Linux内核的工作环境更能接�妇女和少数�群，因为�个人在别人眼
+里�是一个邮件地�。国际化也帮助了公平的实现，因为你无法通过姓��判断人
+的性别。男人有�能��丽，女人也有�能�王刚。大多数在Linux内核上工作过
+并表达过看法的女性对在linux上工作的�历都给出了正�的评价。
+
+对于一些�习惯使用英语的人�说，语言�能是一个引起问题的障�。在邮件列表
+中�正确地表达想法必需良好地掌�语言，所以建议你在��邮件之�最好检查一
+下英文写得是�正确。
+
+
+拆分修改
+--------
+
+Linux内核社区并�喜欢一下接收大段的代�。修改需�被�当地介��讨论并且
+拆分�独立的�段。这几乎完全和公�中的习惯背�而驰。你的想法应该在开�最
+开始的阶段就让大家知�，这样你就�以�时获得对你正在进行的开�的�馈。这
+样也会让社区觉得你是在和他们�作，而�是仅仅把他们当作倾销新功能的对象。
+无论如何，你��一次性地�邮件列表��50�信，你的补��列应该永远用�到
+这么多。
+
+将补�拆开的原因如下：
+
+1) �的补�更有�能被接�，因为它们�需�太多的时间和精力去验�其正确性。
+   一个5行的补�，�能在维护者看了一眼以�就会被接�。而500行的补�则
+   需�数个�时�审查其正确性（所需时间�补�大�增加大约呈指数级增长）。
+
+   当出了问题的时候，�的补�也会让调试�得�常容易。一个一个补�地回溯
+   将会比仔细剖�一个被打上的大补�（这个补�破�了其他东西）容易得多。
+
+2）�光���的补�很��，在�交之��新编排�化简（或者仅仅�新排列）
+   补�也是很��的。
+
+这里有内核开�者Al Viro打的一个比方：
+	“想象一个�师正在给学生批改数学作业。�师并�希望看到学生为了得
+	到正确解法所进行的�试和产生的错误。他希望看到的是最干净最优雅的
+	解答。好学生了解这点，��会把最终解决之�的中间方案�交上去。�
+
+	内核开�也是这样。维护者和评审者�希望看到一个人在解决问题时的�
+	考过程。他们�希望看到简�和优雅的解决方案。
+
+直接给出一�的解决方案，和社区一起�作讨论尚未完�的工作，这两者之间似乎
+很难找到一个平衡点。所以最好尽早开始收集有利于你进行改进的�馈；�时也�
+��修改分�很多��，这样在整个项目都准备好被包�进内核之�，其中的一部
+分�能会先被接收。
+
+必须了解这样�是��接�的：试图将未完�的工作�交进内核，然��找时间修
+�。
+
+
+�明修改的必�性
+----------------
+除了将补�拆���，很��的一点是让Linux社区了解他们为什么需�这样修改。
+你必须�明新功能是有人需�的并且是有用的。
+
+
+记录修改
+--------
+
+当你��补�的时候，需�特别留�邮件正文的内容。因为这里的信�将会�为补
+�的修改记录(ChangeLog)，会被一直�留以备大家查阅。它需�完全地�述补�，
+包括：
+  - 为什么需�这个修改
+  - 补�的总体设计
+  - 实现细节
+  - 测试结果
+
+想了解它具体应该看起��什么，请查阅以下文档中的“ChangeLog�章节：
+  “The Perfect Patch�
+      http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt
+
+
+这些事情有时候�起�很难。�在任何方�都�到完美�能需�好几年时间。这是
+一个�续�高的过程，它需�大�的�心和决心。���放弃，你一定�以�到。
+很多人已��到了，而他们都曾�和现在的你站在�样的起点上。

+以下为正文
+---------------------------------------------------------------------
+
+写作本文档的目的，是为了解释为什么Linux既没有二进制内核接�，也没有稳定
+的内核接�。这里所说的内核接�，是指内核里的接�，而�是内核和用户空间
+的接�。内核到用户空间的接�，是�供给应用程�使用的系统调用，系统调用
+在历�上几乎没有过�化，将�也�会有�化。我有一些�应用程�是在0.9版本
+或者更早版本的内核上编译的，在使用2.6版本内核的Linux�布上�然用得很好
+。用户和应用程�作者�以将这个接�看�是稳定的。
+
+
+执行纲�
+--------
+
+你也许以为自己想�稳定的内核接�，但是你�清楚你�的实际上�是它。你需
+�的其实是稳定的驱动程�，而你�有将驱动程�放到公版内核的�代�树里，
+�有�能达到这个目的。而且这样�还有很多其它好处，正是因为这些好处使得
+Linux能�为强壮，稳定，�熟的�作系统，这也是你最开始选择Linux的原因。
+
+
+入门
+-----
+
+�有那些写驱动程�的“怪人��会担心内核接�的改�，对广大用户�说，既
+看�到内核接�，也�需�去关心它。
+
+首先，我�打算讨论关于任何�GPL许�的内核驱动的法律问题，这些�GPL许�
+的驱动程�包括�公开�代�，���代�，二进制或者是用�代�包装，或者
+是其它任何形�的�能以GPL许�公开�代�的驱动程�。如果有法律问题，请咨
+询律师，我�是一个程�员，所以我�打算探讨技术问题（�是�看法律问题，
+法律问题很实际，并且需�一直关注）。
+
+既然�谈技术问题，我们就有了下�两个主题：二进制内核接�和稳定的内核�
+代�接�。这两个问题是互相关�的，让我们先解决掉二进制接�的问题。
+
+
+二进制内核接�
+--------------
+�如我们有一个稳定的内核�代�接�，那么自然而然的，我们就拥有了稳定的
+二进制接�，是这样的�？错。让我们看看关于Linux内核的几点事实：
+    - �决于所用的C编译器的版本，��的内核数�结构里的结构体的对�方
+�会有差别，代�中��函数的表现形�也�一样（函数是�是被inline编译�
+决于编译器行为）。��的函数的表现形�并���，但是数�结构内部的对�
+方�很关键。
+    - �决于内核的�置选项，��的选项会让内核的很多东西�生改�：
+      - �一个结构体�能包���的�员��
+      - 有的函数�能根本�会被实现（比如编译的时候没有选择SMP支�
+，一些�函数就会被定义�空函数）。
+      - 内核使用的内存会以��的方�对�，这�决于��的内核�置选
+项。
+    - Linux�以在很多的��体系结构的处�器上�行。在�个体系结构上编
+译好的二进制驱动程�，��能在�外一个体系结构上正确的�行。
+
+对于一个特定的内核，满足这些�件并�难，使用�一个C编译器和�样的内核�
+置选项�编译驱动程�模�就�以了。这对于给一个特定Linux�布的特定版本�
+供驱动程�，是完全�以满足需求的。但是如果你�给���布的��版本都�
+布一个驱动程�，就需�在�个�布上用��的内核设置�数都编译一次内核，
+这简直跟噩梦一样。而且还�注�到，�个Linux�布还�供��的Linux内核，
+这些内核都针对��的硬件类型进行了优化（有很多���的处�器，还有��
+的内核设置选项）。所以��布一次驱动程�，都需��供很多��版本的内核
+模�。
+
+相信我，如果你真的�采�这��布方�，一定会慢慢疯掉，我很久以�就有过
+深刻的教训...
+
+
+稳定的内核�代�接�
+--------------------
+
+如果有人�将他的内核驱动程�，放入公版内核的�代�树，而�想让驱动程�
+一直��在最新的内核中�用，那么这个�题将会�得没完没了。
+ 内核开�是�续而且快节�的，从�都�会慢下�。内核开�人员在当�接�中
+找到bug，或者找到更好的实现方�。一旦�现这些，他们就很快会去修改当�的
+接�。修改接��味�，函数��能会改�，结构体�能被扩充或者删�，函数
+的�数也�能�生改�。一旦接�被修改，内核中使用这些接�的地方需��时
+修正，这样�能��所有的东西继续工作。
+
+举一个例�，内核的USB驱动程�接�在USB�系统的整个生命周期中，至少�历
+了三次�写。这些�写解决以下问题：
+    - 把数��从�步模�改���步模�，这个改动�少了一些驱动程�的
+��度，�高了所有USB驱动程�的��率，这样几乎所有的USB设备都能以最大
+速率工作了。
+    - 修改了USB核心代�中为USB驱动分�数�包内存的方�，所有的驱动都
+需��供更多的�数给USB核心，以修正了很多已�被记录在案的死�。
+
+这和一些�闭�代�的�作系统形�鲜明的对比，在那些�作系统上，�得��
+外的维护旧的USB接�。这导致了一个�能性，新的开�者�然会��心使用旧的
+接�，以��当的方�编写代�，进而影�到�作系统的稳定性。
+ 在上�的例�中，所有的开�者都��这些��的改动，在这样的情况下修改代
+价很低。如果Linux��一个稳定的内核�代�接�，那么就得创建一个新的接�
+；旧的，有问题的接�必须一直维护，给Linux USB开�者带��外的工作。既然
+所有的Linux USB驱动的作者都是利用自己的时间工作，那么�求他们去�毫无�
+义的�费�外工作，是��能的。
+ 安全问题对Linux�说�分��。一个安全问题被�现，就会在短时间内得到修
+正。在很多情况下，这将导致Linux内核中的一些接�被�写，以从根本上��安
+全问题。一旦接�被�写，所有使用这些接�的驱动程�，必须�时得到修正，
+以确定安全问题已�得到修�并且��能在未�还有�样的安全问题。如果内核
+内部接���许改�，那么就��能修�这样的安全问题，也��能确认这样的
+安全问题以��会�生。
+开�者一直在清�内核接�。如果一个接�没有人在使用了，它就会被删除。这
+样�以确�内核尽�能的�，而且所有潜在的接�都会得到尽�能完整的测试
+（没有人使用的接�是��能得到良好的测试的）。
+
+
+��什么
+-------
+
+如果你写了一个Linux内核驱动，但是它还�在Linux�代�树里，作为一个开�
+者，你应该怎么�？为�个�布的�个版本�供一个二进制驱动，那简直是一个
+噩梦，�跟上永远处于�化之中的内核接�，也是一件辛苦活。
+很简�，让你的驱动进入内核�代�树（�记得我们在谈论的是以GPL许��行
+的驱动，如果你的代��符�GPL，那么�你好�，你�能自己解决这个问题了，
+你这个�血鬼<把Andrew和Linus对�血鬼的定义链接到这里>）。当你的代�加入
+公版内核�代�树之�，如果一个内核接�改�，你的驱动会直接被修改接�的
+那个人修改。��你的驱动永远都�以编译通过，并且一直工作，你几乎�需�
+�什么事情。
+
+把驱动放到内核�代�树里会有很多的好处：
+    - 驱动的质�会��，而维护�本（对原始作者�说）会下�。
+    - 其他人会给驱动添加新特性。
+    - 其他人会找到驱动中的bug并修�。
+    - 其他人会在驱动中找到性能优化的机会。
+    - 当外部的接�的改�需�修改驱动程�的时候，其他人会修改驱动程�
+。
+    - �需��系任何�行商，这个驱动会自动的��所有的Linux�布一起�
+布。
+
+和别的�作系统相比，Linux为更多��的设备�供现�的驱动，而且能在更多�
+�体系结构的处�器上支�这些设备。这个�过考验的开�模�，必然是错�了

-/* This is the kernel's entry point into the floating point emulator.
-It is called from the kernel with code similar to this:
-
-	mov	fp, #0
-	teqp	pc, #PSR_I_BIT | SVC_MODE
-	ldr	r4, .LC2
-	ldr	pc, [r4]		@ Call FP module USR entry point
-
-The kernel expects the emulator to return via one of two possible
-points of return it passes to the emulator.  The emulator, if
-successful in its emulation, jumps to ret_from_exception and the
-kernel takes care of returning control from the trap to the user code.
-If the emulator is unable to emulate the instruction, it returns to
-fpundefinstr and the kernel halts the user program with a core dump.
-
-This routine does four things:
-
-1) It saves SP into a variable called userRegisters.  The kernel has
-created a struct pt_regs on the stack and saved the user registers
-into it.  See /usr/include/asm/proc/ptrace.h for details.  The
-emulator code uses userRegisters as the base of an array of words from
-which the contents of the registers can be extracted.
-
-2) It locates the FP emulator work area within the TSS structure and
-points `fpa11' to it.
-
-3) It calls EmulateAll to emulate a floating point instruction.
-EmulateAll returns 1 if the emulation was successful, or 0 if not.
-
-4) If an instruction has been emulated successfully, it looks ahead at
-the next instruction.  If it is a floating point instruction, it
-executes the instruction, without returning to user space.  In this
-way it repeatedly looks ahead and executes floating point instructions
-until it encounters a non floating point instruction, at which time it
-returns via _fpreturn.
-
-This is done to reduce the effect of the trap overhead on each
-floating point instructions.  GCC attempts to group floating point
-instructions to allow the emulator to spread the cost of the trap over
-several floating point instructions.  */

-The work in this architecture (ARM26) is that of a great many people.
-
-This is what has happened:
-
-I [Ian Molton] have been trying to repair the ARM26 architecture support, but it has become an impossible task whilst it is still merged with the ARM32 (arch/arm) code. The ARM26 code is too different to be sensible to keep with the ARM32 code now, and Russell King really doesnt have the time to maintain the ARM26 code. Add to that that most ARM32 developers dont know about or care about ARM26 when writing patches, and you have a reall mess.
-
-As a result, I've split it off into a new architecture of its own. I've named it arm26 since these CPUs have only a 26 bit address space, unlike the other ARMs.
-
-The upheaval in moving around so many source files and chopping out vasty ammounts of cruft was enormous, and the copyright of many files is sometimes unclear. Because of this, I am writing this, in order that no-one is left out / misaccredited / blamed for any of the code.
-
-People I KNOW have made major contributions to the code:
-
-David Alan Gilbert (former maintainer of ARM26 bits)
-Philip Blundell
-Russell King
-Keith Owens
-
-also thanks to Nicholas Pitre for hints, and for the basis or our XIP support.
-
-Currently maintaing the code are
-
-Ian Molton (Maintainer / Archimedes)
-John Appleby (kernel / A5K)
-
-If anyone has a problem with attributions in header files / source files, please do contact me to straighten things out.

- *  FIQ support written by Philip Blundell <philb@gnu.org>, 1998.
- *
- *  FIQ support re-written by Russell King to be more generic

- * We now properly support a method by which the FIQ handlers can

- * the FIQ vector itself.
- *
- * Operation is as follows:
- *  1. Owner A claims FIQ:
- *     - default_fiq relinquishes control.
- *  2. Owner A:
- *     - inserts code.
- *     - sets any registers,
- *     - enables FIQ.
- *  3. Owner B claims FIQ:
- *     - if owner A has a relinquish function.
- *       - disable FIQs.
- *       - saves any registers.
- *       - returns zero.
- *  4. Owner B:
- *     - inserts code.
- *     - sets any registers,
- *     - enables FIQ.
- *  5. Owner B releases FIQ:
- *     - Owner A is asked to reacquire FIQ:
- *	 - inserts code.
- *	 - restores saved registers.
- *	 - enables FIQ.

- * efficient, especially as they return an error value in addition to
- * the "real" return value.
- *
- * __get_user_X
- *
- * Inputs:	r0 contains the address
- * Outputs:	r0 is the error code
- *		r1, r2 contains the zero-extended value
- *		lr corrupted
- *
- * No other registers must be altered.  (see include/asm-arm/uaccess.h
- * for specific ASM register usage).
- *
- * Note that ADDR_LIMIT is either 0 or 0xc0000000.
- * Note also that it is intended that __get_user_bad is not global.

-   1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
-   multiplies two USItype integers MULTIPLER and MULTIPLICAND,
-   and generates a two-part USItype product in HIGH_PROD and
-   LOW_PROD.
-
-   2) __umulsidi3(a,b) multiplies two USItype integers A and B,
-   and returns a UDItype product.  This is just a variant of umul_ppmm.
-
-   3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-   denominator) divides a two-word unsigned integer, composed by the
-   integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
-   places the quotient in QUOTIENT and the remainder in REMAINDER.
-   HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
-   If, in addition, the most significant bit of DENOMINATOR must be 1,
-   then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
-
-   4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-   denominator).  Like udiv_qrnnd but the numbers are signed.  The
-   quotient is rounded towards 0.
-
-   5) count_leading_zeros(count, x) counts the number of zero-bits from
-   the msb to the first non-zero bit.  This is the number of steps X
-   needs to be shifted left to set the msb.  Undefined for X == 0.
-
-   6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
-   high_addend_2, low_addend_2) adds two two-word unsigned integers,
-   composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
-   LOW_ADDEND_2 respectively.  The result is placed in HIGH_SUM and
-   LOW_SUM.  Overflow (i.e. carry out) is not stored anywhere, and is
-   lost.
-
-   7) sub_ddmmss(high_difference, low_difference, high_minuend,
-   low_minuend, high_subtrahend, low_subtrahend) subtracts two
-   two-word unsigned integers, composed by HIGH_MINUEND_1 and
-   LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
-   respectively.  The result is placed in HIGH_DIFFERENCE and
-   LOW_DIFFERENCE.  Overflow (i.e. carry out) is not stored anywhere,
-   and is lost.

- * Requirement:

- *  second level page tables on 32-bit ARMs.
- *
- * FIXME - this comment is *out of date*
- * Theory:
- *  We "misuse" the Linux memory management system.  We use alloc_page
- *  to allocate a page and then mark it as reserved.  The Linux memory
- *  management system will then ignore the "offset", "next_hash" and
- *  "pprev_hash" entries in the mem_map for this page.
- *
- *  We then use a bitstring in the "offset" field to mark which segments
- *  of the page are in use, and manipulate this as required during the
- *  allocation and freeing of these small pages.
- *
- *  We also maintain a queue of pages being used for this purpose using
- *  the "next_hash" and "pprev_hash" entries of mem_map;

-2002-01-19  Russell King <rmk@arm.linux.org.uk>
-
-	* fpa11.h - Add documentation
-	          - remove userRegisters pointer from this structure.
-	          - add new method to obtain integer register values.
-	* softfloat.c - Remove float128
-	* softfloat.h - Remove float128
-	* softfloat-specialize - Remove float128
-
-	* The FPA11 structure is not a kernel-specific data structure.
-	  It is used by users of ptrace to examine the values of the
-	  floating point registers.  Therefore, any changes to the
-	  FPA11 structure (size or position of elements contained
-	  within) have to be well thought out.
-
-	* Since 128-bit float requires the FPA11 structure to change
-	  size, it has been removed.  128-bit float is currently unused,
-	  and needs various things to be re-worked so that we won't
-	  overflow the available space in the task structure.
-
-	* The changes are designed to break any patch that goes on top
-	  of this code, so that the authors properly review their changes.
-
-1999-08-19  Scott Bambrough  <scottb@netwinder.org>
-
-	* fpmodule.c - Changed version number to 0.95
-	* fpa11.h - modified FPA11, FPREG structures
-	* fpa11.c - Changes due to FPA11, FPREG structure alterations.
-	* fpa11_cpdo.c - Changes due to FPA11, FPREG structure alterations.
-	* fpa11_cpdt.c - Changes due to FPA11, FPREG structure alterations.
-	* fpa11_cprt.c - Changes due to FPA11, FPREG structure alterations.
-	* single_cpdo.c - Changes due to FPA11, FPREG structure alterations.
-	* double_cpdo.c - Changes due to FPA11, FPREG structure alterations.
-	* extended_cpdo.c - Changes due to FPA11, FPREG structure alterations.
-
-	* I discovered several bugs.  First and worst is that the kernel
-	  passes in a pointer to the FPE's state area.	This is defined
-	  as a struct user_fp (see user.h).  This pointer was cast to a
-	  FPA11*.  Unfortunately FPA11 and user_fp are of different sizes;
-	  user_fp is smaller.  This meant that the FPE scribbled on things
-	  below its area, which is bad, as the area is in the thread_struct
-	  embedded in the process task structure.  Thus we were scribbling
-	  over one of the most important structures in the entire OS.
-
-	* user_fp and FPA11 have now been harmonized.  Most of the changes
-	  in the above code were dereferencing problems due to moving the
-	  register type out of FPREG, and getting rid of the union variable
-	  fpvalue.
-
-	* Second I noticed resetFPA11 was not always being called for a
-	  task.  This should happen on the first floating point exception
-	  that occurs.	It is controlled by init_flag in FPA11.  The
-	  comment in the code beside init_flag state the kernel guarantees
-	  this to be zero.  Not so.  I found that the kernel recycles task
-	  structures, and that recycled ones may not have init_flag zeroed.
-	  I couldn't even find anything that guarantees it is zeroed when
-	  when the task structure is initially allocated.  In any case
-	  I now initialize the entire FPE state in the thread structure to
-	  zero when allocated and recycled.  See alloc_task_struct() and
-	  flush_thread() in arch/arm/process.c.  The change to
-	  alloc_task_struct() may not be necessary, but I left it in for
-	  completeness (better safe than sorry).

-1998-11-23  Scott Bambrough  <scottb@netwinder.org>
-
-	* README.FPE - fix typo in description of lfm/sfm instructions
-	* NOTES - Added file to describe known bugs/problems 
-	* fpmodule.c - Changed version number to 0.94
-
-1998-11-20  Scott Bambrough  <scottb@netwinder.org>
-
-	* README.FPE - fix description of URD, NRM instructions
-	* TODO - remove URD, NRM instructions from TODO list
-	* single_cpdo.c - implement URD, NRM
-	* double_cpdo.c - implement URD, NRM
-	* extended_cpdo.c - implement URD, NRM
-
-1998-11-19  Scott Bambrough  <scottb@netwinder.org>
-
-	* ChangeLog - Added this file to track changes made.
-	* fpa11.c - added code to initialize register types to typeNone
-	* fpa11_cpdt.c - fixed bug in storeExtended (typeExtended changed to
-	  typeDouble in switch statement)

-/* This is the kernel's entry point into the floating point emulator.
-It is called from the kernel with code similar to this:
-
-	mov	fp, #0
-	teqp	pc, #PSR_I_BIT | MODE_SVC
-	ldr	r4, .LC2
-	ldr	pc, [r4]		@ Call FP module USR entry point
-
-The kernel expects the emulator to return via one of two possible
-points of return it passes to the emulator.  The emulator, if
-successful in its emulation, jumps to ret_from_exception and the
-kernel takes care of returning control from the trap to the user code.
-If the emulator is unable to emulate the instruction, it returns to
-fpundefinstr and the kernel halts the user program with a core dump.
-
-This routine does four things:
-
-1) It saves SP into a variable called userRegisters.  The kernel has
-created a struct pt_regs on the stack and saved the user registers
-into it.  See /usr/include/asm/proc/ptrace.h for details.  The
-emulator code uses userRegisters as the base of an array of words from
-which the contents of the registers can be extracted.
-
-2) It locates the FP emulator work area within the TSS structure and
-points `fpa11' to it.
-
-3) It calls EmulateAll to emulate a floating point instruction.
-EmulateAll returns 1 if the emulation was successful, or 0 if not.
-
-4) If an instruction has been emulated successfully, it looks ahead at
-the next instruction.  If it is a floating point instruction, it
-executes the instruction, without returning to user space.  In this
-way it repeatedly looks ahead and executes floating point instructions
-until it encounters a non floating point instruction, at which time it
-returns via _fpreturn.
-
-This is done to reduce the effect of the trap overhead on each
-floating point instructions.  GCC attempts to group floating point
-instructions to allow the emulator to spread the cost of the trap over
-several floating point instructions.  */

+ * Xen event channels
+ *
+ * Xen models interrupts with abstract event channels.  Because each
+ * domain gets 1024 event channels, but NR_IRQ is not that large, we
+ * must dynamically map irqs<->event channels.  The event channels
+ * interface with the rest of the kernel by defining a xen interrupt
+ * chip.  When an event is recieved, it is mapped to an irq and sent
+ * through the normal interrupt processing path.
+ *
+ * There are four kinds of events which can be mapped to an event
+ * channel:
+ *
+ * 1. Inter-domain notifications.  This includes all the virtual
+ *    device events, since they're driven by front-ends in another domain
+ *    (typically dom0).
+ * 2. VIRQs, typically used for timers.  These are per-cpu events.
+ * 3. IPIs.
+ * 4. Hardware interrupts. Not supported at present.

+/*
+ * Xen mmu operations
+ *
+ * This file contains the various mmu fetch and update operations.
+ * The most important job they must perform is the mapping between the
+ * domain's pfn and the overall machine mfns.
+ *
+ * Xen allows guests to directly update the pagetable, in a controlled
+ * fashion.  In other words, the guest modifies the same pagetable
+ * that the CPU actually uses, which eliminates the overhead of having
+ * a separate shadow pagetable.
+ *
+ * In order to allow this, it falls on the guest domain to map its
+ * notion of a "physical" pfn - which is just a domain-local linear
+ * address - into a real "machine address" which the CPU's MMU can
+ * use.
+ *
+ * A pgd_t/pmd_t/pte_t will typically contain an mfn, and so can be
+ * inserted directly into the pagetable.  When creating a new
+ * pte/pmd/pgd, it converts the passed pfn into an mfn.  Conversely,
+ * when reading the content back with __(pgd|pmd|pte)_val, it converts
+ * the mfn back into a pfn.
+ *
+ * The other constraint is that all pages which make up a pagetable
+ * must be mapped read-only in the guest.  This prevents uncontrolled
+ * guest updates to the pagetable.  Xen strictly enforces this, and
+ * will disallow any pagetable update which will end up mapping a
+ * pagetable page RW, and will disallow using any writable page as a
+ * pagetable.
+ *
+ * Naively, when loading %cr3 with the base of a new pagetable, Xen
+ * would need to validate the whole pagetable before going on.
+ * Naturally, this is quite slow.  The solution is to "pin" a
+ * pagetable, which enforces all the constraints on the pagetable even
+ * when it is not actively in use.  This menas that Xen can be assured
+ * that it is still valid when you do load it into %cr3, and doesn't
+ * need to revalidate it.

+ * Xen hypercall batching.
+ *
+ * Xen allows multiple hypercalls to be issued at once, using the
+ * multicall interface.  This allows the cost of trapping into the
+ * hypervisor to be amortized over several calls.
+ *
+ * This file implements a simple interface for multicalls.  There's a
+ * per-cpu buffer of outstanding multicalls.  When you want to queue a
+ * multicall for issuing, you can allocate a multicall slot for the
+ * call and its arguments, along with storage for space which is
+ * pointed to by the arguments (for passing pointers to structures,
+ * etc).  When the multicall is actually issued, all the space for the
+ * commands and allocated memory is freed for reuse.
+ *
+ * Multicalls are flushed whenever any of the buffers get full, or
+ * when explicitly requested.  There's no way to get per-multicall
+ * return results back.  It will BUG if any of the multicalls fail.

+   will end up resetting it each time.  It could be filtered, but
+   doing so has complications when the ktime clocksource is not yet
+   the xen clocksource (ie, at boot time).
+
+   The new vcpu_op-based timer interface allows the tick timer period
+   to be changed or turned off.  The tick timer is not useful as a
+   periodic timer because events are only delivered to running vcpus.
+   The one-shot timer can report when a timeout is in the past, so
+   set_next_event is capable of returning -ETIME when appropriate.
+   This interface is used when available.

+   a more refined determination of what to do.
+
+   The stack format at this point is:
+	----------------
+	 ss		: (ss/esp may be present if we came from usermode)
+	 esp		:
+	 eflags		}  outer exception info
+	 cs		}

+	----------------
+
+   In order to deliver the nested exception properly, we need to shift

+   sits just under the outer exception info.  This means that when we
+   handle the exception, we do it in the context of the outer exception
+   rather than starting a new one.
+
+   The only caveat is that if the outer eax hasn't been
+   restored yet (ie, it's still on stack), we need to insert
+   its value into the SAVE_ALL state before going on, since
+   it's usermode state which we eventually need to restore.

-/*
- * Detailed Description:
- *
- * This block implements the I2C interface to the slave devices like the
- * Atmel 24C32 EEPROM and the MAX 1619 Sensors device. The I2C Master interface
- * can be controlled by the SCMB block. And the SCMB block kicks in only when
- * using the Ethernet Mode of operation and __not__ the SysAD mode
- *
- * The SCMB controls the two modes: MDIO and the I2C. The MDIO mode is used to
- * communicate with the Quad-PHY from Marvel. The I2C is used to communicate
- * with the I2C slave devices.  It seems that the driver does not explicitly
- * deal with the control of SDA and SCL serial lines. So, the driver will set
- * the slave address, drive the command and then the data.  The SCMB will then
- * control the two serial lines as required.
- *
- * It seems the documents are very unclear abt this. Hence, I took some time
- * out to write the desciption to have an idea of how the I2C can actually
- * work. Currently, this Linux driver wont be integrated into the generic Linux
- * I2C framework. And finally, the I2C interface is also known as the 2BI
- * interface. 2BI means 2-bit interface referring to SDA and SCL serial lines
- * respectively.

+ * The hardware uses an LFSR counting sequence to determine when to capture

+ * numerical order. The SPU PC capture is done when the LFSR sequence reaches
+ * the last value in the sequence.  Hence the user specified value N
+ * corresponds to the LFSR number that is N from the end of the sequence.
+ *
+ * To avoid the time to compute the LFSR, a lookup table is used.  The 24 bit
+ * LFSR sequence is broken into four ranges.  The spacing of the precomputed
+ * values is adjusted in each range so the error between the user specifed
+ * number (N) of events between samples and the actual number of events based
+ * on the precomputed value will be les then about 6.2%.  Note, if the user
+ * specifies N < 2^16, the LFSR value that is 2^16 from the end will be used.
+ * This is to prevent the loss of samples because the trace buffer is full.

-/*
- *  linux/kernel/arch/arm/drivers/block/fd1772.c
- *  Based on ataflop.c in the m68k Linux
- *  Copyright (C) 1993  Greg Harp
- *  Atari Support by Bjoern Brauel, Roman Hodek
- *  Archimedes Support by Dave Gilbert (linux@treblig.org)
- *
- *  Big cleanup Sep 11..14 1994 Roman Hodek:
- *   - Driver now works interrupt driven
- *   - Support for two drives; should work, but I cannot test that :-(
- *   - Reading is done in whole tracks and buffered to speed up things
- *   - Disk change detection and drive deselecting after motor-off
- *     similar to TOS
- *   - Autodetection of disk format (DD/HD); untested yet, because I
- *     don't have an HD drive :-(
- *
- *  Fixes Nov 13 1994 Martin Schaller:
- *   - Autodetection works now
- *   - Support for 5 1/4" disks
- *   - Removed drive type (unknown on atari)
- *   - Do seeks with 8 Mhz
- *
- *  Changes by Andreas Schwab:
- *   - After errors in multiple read mode try again reading single sectors
- *  (Feb 1995):
- *   - Clean up error handling
- *   - Set blk_size for proper size checking
- *   - Initialize track register when testing presence of floppy
- *   - Implement some ioctl's
- *
- *  Changes by Torsten Lang:
- *   - When probing the floppies we should add the FDC1772CMDADD_H flag since
- *     the FDC1772 will otherwise wait forever when no disk is inserted...
- *
- *  Things left to do:
- *   - Formatting
- *   - Maybe a better strategy for disk change detection (does anyone
- *     know one?)
- *   - There are some strange problems left: The strangest one is
- *     that, at least on my TT (4+4MB), the first 2 Bytes of the last
- *     page of the TT-Ram (!) change their contents (some bits get
- *     set) while a floppy DMA is going on. But there are no accesses
- *     to these memory locations from the kernel... (I tested that by
- *     making the page read-only). I cannot explain what's going on...
- *   - Sometimes the drive-change-detection stops to work. The
- *     function is still called, but the WP bit always reads as 0...
- *     Maybe a problem with the status reg mode or a timing problem.
- *     Note 10/12/94: The change detection now seems to work reliably.
- *     There is no proof, but I've seen no hang for a long time...
- *
- * ARCHIMEDES changes: (gilbertd@cs.man.ac.uk)
- *     26/12/95 - Changed all names starting with FDC to FDC1772
- *                Removed all references to clock speed of FDC - we're stuck with 8MHz
- *                Modified disk_type structure to remove HD formats
- *
- *      7/ 1/96 - Wrote FIQ code, removed most remaining atariisms
- *
- *     13/ 1/96 - Well I think its read a single sector; but there is a problem
- *                fd_rwsec_done which is called in FIQ mode starts another transfer
- *                off (in fd_rwsec) while still in FIQ mode.  Because its still in
- *                FIQ mode it can't service the DMA and loses data. So need to
- *                heavily restructure.
- *     14/ 1/96 - Found that the definitions of the register numbers of the
- *                FDC were multiplied by 2 in the header for the 16bit words
- *                of the atari so half the writes were going in the wrong place.
- *                Also realised that the FIQ entry didn't make any attempt to
- *                preserve registers or return correctly; now in assembler.
- *
- *     11/ 2/96 - Hmm - doesn't work on real machine.  Auto detect doesn't
- *                and hacking that past seems to wait forever - check motor
- *                being turned on.
- *
- *     17/ 2/96 - still having problems - forcing track to -1 when selecting
- *                new drives seems to allow it to read first few sectors
- *                but then we get solid hangs at apparently random places
- *                which change depending what is happening.
- *
- *      9/ 3/96 - Fiddled a lot of stuff around to move to kernel 1.3.35
- *                A lot of fiddling in DMA stuff. Having problems with it
- *                constnatly thinking its timeing out. Ah - its timeout
- *                was set to (6*HZ) rather than jiffies+(6*HZ).  Now giving
- *                duff data!
- *
- *      5/ 4/96 - Made it use the new IOC_ macros rather than *ioc
- *                Hmm - giving unexpected FIQ and then timeouts
- *     18/ 8/96 - Ran through indent -kr -i8
- *                Some changes to disc change detect; don't know how well it
- *                works.
- *     24/ 8/96 - Put all the track buffering code back in from the atari
- *                code - I wonder if it will still work... No :-)
- *                Still works if I turn off track buffering.
- *     25/ 8/96 - Changed the timer expires that I'd added back to be 
- *                jiffies + ....; and it all sprang to life! Got 2.8K/sec
- *                off a cp -r of a 679K disc (showed 94% cpu usage!)
- *                (PC gets 14.3K/sec - 0% CPU!) Hmm - hard drive corrupt!
- *                Also perhaps that compile was with cache off.
- *                changed cli in fd_readtrack_check to cliIF
- *                changed vmallocs to kmalloc (whats the difference!!)
- *                Removed the busy wait loop in do_fd_request and replaced
- *                by a routine on tq_immediate; only 11% cpu on a dd off the
- *                raw disc - but the speed is the same.
- *	1/ 9/96 - Idea (failed!) - set the 'disable spin-up sequence'
- *		  when we read the track if we know the motor is on; didn't
- *		  help - perhaps we have to do it in stepping as well.
- *		  Nope. Still doesn't help.
- *		  Hmm - what seems to be happening is that fd_readtrack_check
- *		  is never getting called. Its job is to terminate the read
- *		  just after we think we should have got the data; otherwise
- *		  the fdc takes 1 second to timeout; which is what's happening
- *		  Now I can see 'readtrack_timer' being set (which should do the
- *		  call); but it never seems to be called - hmm!
- *		  OK - I've moved the check to my tq_immediate code -
- *		  and it WORKS! 13.95K/second at 19% CPU.
- *		  I wish I knew why that timer didn't work.....
- *
- *     16/11/96 - Fiddled and frigged for 2.0.18
- *
- * DAG 30/01/99 - Started frobbing for 2.2.1
- * DAG 20/06/99 - A little more frobbing:
- *		  Included include/asm/uaccess.h for get_user/put_user
- *
- * DAG  1/09/00 - Dusted off for 2.4.0-test7
- *                MAX_SECTORS was name clashing so it is now FD1772_...
- *                Minor parameter, name layouts for 2.4.x differences

-/*
- * Change list:
- *
- *  3/2/96:DAG: Started a change list :-)
- *              Set the hardsect_size pointers up since we are running 256 byte
- *                sectors
- *              Added DMA code, put it into the rw_intr
- *              Moved RCAL out of generic interrupt code - don't want to do it
- *                while DMA'ing - its now in individual handlers.
- *              Took interrupt handlers off task queue lists and called
- *                directly - not sure of implications.
- *
- * 18/2/96:DAG: Well its reading OK I think, well enough for image file code
- *              to find the image file; but now I've discovered that I actually
- *              have to put some code in for image files.
- *
- *              Added stuff for image files; seems to work, but I've not
- *              got a multisegment image file (I don't think!).
- *              Put in a hack (yep a real hack) for multiple cylinder reads.
- *              Not convinced its working.
- *
- *  5/4/96:DAG: Added asm/hardware.h and use IOC_ macros
- *              Rewrote dma code in mfm.S (again!) - now takes a word at a time
- *              from main RAM for speed; still doesn't feel speedy!
- *
- * 20/4/96:DAG: After rewriting mfm.S a heck of a lot of times and speeding
- *              things up, I've finally figured out why its so damn slow.
- *              Linux is only reading a block at a time, and so you never
- *              get more than 1K per disc revoloution ~=60K/second.
- *
- * 27/4/96:DAG: On Russell's advice I change ll_rw_blk.c to ask it to
- *              join adjacent blocks together. Everything falls flat on its
- *              face.
- *              Four hours of debugging later; I hadn't realised that
- *              ll_rw_blk would be so generous as to join blocks whose
- *              results aren't going into consecutive buffers.
- * 
- *              OK; severe rehacking of mfm_rw_interrupt; now end_request's
- *              as soon as its DMA'd each request.  Odd thing is that
- *              we are sometimes getting interrupts where we are not transferring
- *              any data; why? Is that what happens when you miss? I doubt
- *              it; are we too fast? No - its just at command ends. Got 240K/s
- *              better than before, but RiscOS hits 480K/s
- *
- * 25/6/96:RMK: Fixed init code to allow the MFM podule to work.  Increased the
- *              number of errors for my Miniscribe drive (8425).
- *
- * 30/6/96:DAG: Russell suggested that a check drive 0 might turn the LEDs off
- *              - so in request_done just before it clears Busy it sends a
- *              check drive 0 - and the LEDs go off!!!!
- *
- *              Added test for mainboard controller. - Removes need for separate
- *              define.
- *
- * 13/7/96:DAG: Changed hardware sectore size to 512 in attempt to make
- *              IM drivers work.
- * 21/7/96:DAG: Took out old image file stuff (accessing it now produces an IO
- *              error.)
- *
- * 17/8/96:DAG: Ran through indent -kr -i8; evil - all my nice 2 character indents
- *              gone :-( Hand modified afterwards.
- *		Took out last remains of the older image map system.
- *
- * 22/9/96:DAG:	Changed mfm.S so it will carry on DMA'ing til; BSY is dropped
- *		Changed mfm_rw_intr so that it doesn't follow the error
- *		code until BSY is dropped. Nope - still broke. Problem
- *		may revolve around when it reads the results for the error
- *		number?
- *
- *16/11/96:DAG:	Modified for 2.0.18; request_irq changed
- *
- *17/12/96:RMK: Various cleanups, reorganisation, and the changes for new IO system.
- *		Improved probe for onboard MFM chip - it was hanging on my A5k.
- *		Added autodetect CHS code such that we don't rely on the presence
- *		of an ADFS boot block.  Added ioport resource manager calls so
- *		that we don't clash with already-running hardware (eg. RiscPC Ether
- *		card slots if someone tries this)!
- *
- * 17/1/97:RMK:	Upgraded to 2.1 kernels.
- *
- *  4/3/98:RMK:	Changed major number to 21.
- *
- * 27/6/98:RMK:	Changed asm/delay.h to linux/delay.h for mdelay().

-/*
- * Possible enhancements:
- *  Multi-thread the code so that it is possible that while one drive
- *  is seeking, the other one can be reading data/seeking as well.
- *  This would be a performance boost with dual drive systems.

-	  This option adds support for ACPI suspend states.

-	  With this option, you will be able to put the system "to sleep". 
-	  Sleep states are low power states for the system and devices. All
-	  of the system operating state is saved to either memory or disk
-	  (depending on the state), to allow the system to resume operation
-	  quickly at your request.
-
-	  Although this option sounds really nifty, barely any of the device
-	  drivers have been converted to the new driver model and hence few
-	  have proper power management support.

+   what I think is a useful subset in order to fit it into 32 bits.
+
+   Especially note that the #VRD_HOT alarms are missing because we provide

+
+   If libsensors is extended to support 64 bit values, this could be revisited.

+Welcome, friend reader, to lguest.
+
+Lguest is an adventure, with you, the reader, as Hero.  I can't think of many
+5000-line projects which offer both such capability and glimpses of future
+potential; it is an exciting time to be delving into the source!
+
+But be warned; this is an arduous journey of several hours or more!  And as we
+know, all true Heroes are driven by a Noble Goal.  Thus I offer a Beer (or
+equivalent) to anyone I meet who has completed this documentation.
+
+So get comfortable and keep your wits about you (both quick and humorous).
+Along your way to the Noble Goal, you will also gain masterly insight into
+lguest, and hypervisors and x86 virtualization in general.
+
+Our Quest is in seven parts: (best read with C highlighting turned on)
+
+I) Preparation
+	- In which our potential hero is flown quickly over the landscape for a
+	  taste of its scope.  Suitable for the armchair coders and other such
+	  persons of faint constitution.
+
+II) Guest
+	- Where we encounter the first tantalising wisps of code, and come to
+	  understand the details of the life of a Guest kernel.
+
+III) Drivers
+	- Whereby the Guest finds its voice and become useful, and our
+	  understanding of the Guest is completed.
+
+IV) Launcher
+	- Where we trace back to the creation of the Guest, and thus begin our
+	  understanding of the Host.
+
+V) Host
+	- Where we master the Host code, through a long and tortuous journey.
+	  Indeed, it is here that our hero is tested in the Bit of Despair.
+
+VI) Switcher
+	- Where our understanding of the intertwined nature of Guests and Hosts
+	  is completed.
+
+VII) Mastery
+	- Where our fully fledged hero grapples with the Great Question:
+	  "What next?"
+
+make Preparation!
+Rusty Russell.

+ * visitation in the middle of the Linux code, and yet make sure that Guests
+ * can talk directly to other Guests, not just the Launcher.
+ *

+ * address inside the Launcher process).  We don't, however, use this key
+ * directly.
+ *
+ * We want Guests which share memory to be able to DMA to each other: two
+ * Launchers can mmap memory the same file, then the Guests can communicate.
+ * Fortunately, the futex code provides us with a way to get a "union
+ * futex_key" corresponding to the memory lying at a virtual address: if the
+ * two processes share memory, the "union futex_key" for that memory will match
+ * even if the memory is mapped at different addresses in each.  So we always
+ * convert the keys to "union futex_key"s to compare them.
+ *
+ * Before we dive into this though, we need to look at another set of helper
+ * routines used throughout the Host kernel code to access Guest memory.

+ * A hypervisor allows multiple Operating Systems to run on a single machine.
+ * To quote David Wheeler: "Any problem in computer science can be solved with
+ * another layer of indirection."
+ *
+ * We keep things simple in two ways.  First, we start with a normal Linux
+ * kernel and insert a module (lg.ko) which allows us to run other Linux
+ * kernels the same way we'd run processes.  We call the first kernel the Host,
+ * and the others the Guests.  The program which sets up and configures Guests
+ * (such as the example in Documentation/lguest/lguest.c) is called the
+ * Launcher.
+ *
+ * Secondly, we only run specially modified Guests, not normal kernels.  When
+ * you set CONFIG_LGUEST to 'y' or 'm', this automatically sets
+ * CONFIG_LGUEST_GUEST=y, which compiles this file into the kernel so it knows
+ * how to be a Guest.  This means that you can use the same kernel you boot
+ * normally (ie. as a Host) as a Guest.
+ *
+ * These Guests know that they cannot do privileged operations, such as disable
+ * interrupts, and that they have to ask the Host to do such things explicitly.
+ * This file consists of all the replacements for such low-level native
+ * hardware operations: these special Guest versions call the Host.
+ *
+ * So how does the kernel know it's a Guest?  The Guest starts at a special
+ * entry point marked with a magic string, which sets up a few things then
+ * calls here.  We replace the native functions in "struct paravirt_ops"
+ * with our Guest versions, then boot like normal. :*/

+ * Page Table Handling.
+ *
+ * Now would be a good time to take a rest and grab a coffee or similarly
+ * relaxing stimulant.  The easy parts are behind us, and the trek gradually
+ * winds uphill from here.
+ *
+ * Quick refresher: memory is divided into "pages" of 4096 bytes each.  The CPU
+ * maps virtual addresses to physical addresses using "page tables".  We could
+ * use one huge index of 1 million entries: each address is 4 bytes, so that's
+ * 1024 pages just to hold the page tables.   But since most virtual addresses
+ * are unused, we use a two level index which saves space.  The CR3 register
+ * contains the physical address of the top level "page directory" page, which
+ * contains physical addresses of up to 1024 second-level pages.  Each of these
+ * second level pages contains up to 1024 physical addresses of actual pages,
+ * or Page Table Entries (PTEs).
+ *
+ * Here's a diagram, where arrows indicate physical addresses:
+ *
+ * CR3 ---> +---------+
+ *	    |  	   --------->+---------+
+ *	    |	      |	     | PADDR1  |
+ *	  Top-level   |	     | PADDR2  |
+ *	  (PMD) page  |	     | 	       |
+ *	    |	      |	   Lower-level |
+ *	    |	      |	   (PTE) page  |
+ *	    |	      |	     |	       |
+ *	      ....    	     	 ....
+ *
+ * So to convert a virtual address to a physical address, we look up the top
+ * level, which points us to the second level, which gives us the physical
+ * address of that page.  If the top level entry was not present, or the second
+ * level entry was not present, then the virtual address is invalid (we
+ * say "the page was not mapped").
+ *
+ * Put another way, a 32-bit virtual address is divided up like so:
+ *
+ *  1 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
+ * |<---- 10 bits ---->|<---- 10 bits ---->|<------ 12 bits ------>|
+ *    Index into top     Index into second      Offset within page
+ *  page directory page    pagetable page
+ *
+ * The kernel spends a lot of time changing both the top-level page directory
+ * and lower-level pagetable pages.  The Guest doesn't know physical addresses,
+ * so while it maintains these page tables exactly like normal, it also needs
+ * to keep the Host informed whenever it makes a change: the Host will create

+ * Anyway, the GDT entry contains a base (the start address of the segment), a
+ * limit (the size of the segment - 1), and some flags.  Sounds simple, and it
+ * would be, except those zany Intel engineers decided that it was too boring

+ *
+ * He also points out that we don't implement set_mac_address, so users cannot
+ * change the devices hardware address.  When I asked why one would want to:
+ * "Bonding, and situations where you /do/ want the MAC address to "leak" out
+ * of the host onto the wider net."
+ *
+ * Finally, he would like module unloading: "It is not unrealistic to think of
+ * [un|re|]loading the net support module in an lguest guest.  And, adding
+ * module support makes the programmer more responsible, because they now have
+ * to learn to clean up after themselves.  Any driver that cannot clean up

+ *	Ok the logic behind the 8390 is very simple:
+ *	
+ *	Things to know
+ *		- IRQ delivery is asynchronous to the PCI bus
+ *		- Blocking the local CPU IRQ via spin locks was too slow
+ *		- The chip has register windows needing locking work
+ *	
+ *	So the path was once (I say once as people appear to have changed it
+ *	in the mean time and it now looks rather bogus if the changes to use
+ *	disable_irq_nosync_irqsave are disabling the local IRQ)
+ *	
+ *	
+ *		Take the page lock
+ *		Mask the IRQ on chip
+ *		Disable the IRQ (but not mask locally- someone seems to have
+ *			broken this with the lock validator stuff)
+ *			[This must be _nosync as the page lock may otherwise
+ *				deadlock us]
+ *		Drop the page lock and turn IRQs back on
+ *		
+ *		At this point an existing IRQ may still be running but we can't
+ *		get a new one
+ *	
+ *		Take the lock (so we know the IRQ has terminated) but don't mask
+ *	the IRQs on the processor
+ *		Set irqlock [for debug]
+ *	
+ *		Transmit (slow as ****)
+ *	
+ *		re-enable the IRQ
+ *	
+ *	
+ *	We have to use disable_irq because otherwise you will get delayed
+ *	interrupts on the APIC bus deadlocking the transmit path.
+ *	
+ *	Quite hairy but the chip simply wasn't designed for SMP and you can't
+ *	even ACK an interrupt without risking corrupting other parallel
+ *	activities on the chip." [lkml, 25 Jul 2007]

+ * 2     2     TxD       <-  B.TxD

+ *
+ * As you can immediately notice the wiring of the RTS, DTR and DSR signals
+ * is a bit odd.  This makes the handling of port B unnecessarily

  * Host Controller Drivers (HCDs) place all the URBs for a particular
  * endpoint in a queue.  Normally the queue advances as the controller
  * hardware processes each request.  But when an URB terminates with an
- * error its queue stops, at least until that URB's completion routine

- * its unlinked URBs have been fully retired, with their completion
- * routines run, even if that's not until some time after the original
- * completion handler returns.  Normally the same behavior and guarantees
- * apply when an URB terminates because it was unlinked; however if an
- * URB is unlinked before the hardware has started to execute it, then
- * its queue is not guaranteed to stop until all the preceding URBs have
- * completed.
- *
- * This means that USB device drivers can safely build deep queues for
- * large or complex transfers, and clean them up reliably after any sort
- * of aborted transfer by unlinking all pending URBs at the first fault.
- *
- * Note that an URB terminating early because a short packet was received
- * will count as an error if and only if the URB_SHORT_NOT_OK flag is set.
- * Also, that all unlinks performed in any URB completion handler must
- * be asynchronous.
- *
- * Queues for isochronous endpoints are treated differently, because they
- * advance at fixed rates.  Such queues do not stop when an URB is unlinked.
- * An unlinked URB may leave a gap in the stream of packets.  It is undefined
- * whether such gaps can be filled in.
- *
- * When a control URB terminates with an error, it is likely that the
- * status stage of the transfer will not take place, even if it is merely
- * a soft error resulting from a short-packet with URB_SHORT_NOT_OK set.
+ * error its queue generally stops (see below), at least until that URB's
+ * completion routine returns.  It is guaranteed that a stopped queue

+ * with their completion routines run, even if that's not until some time
+ * after the original completion handler returns.  The same behavior and
+ * guarantee apply when an URB terminates because it was unlinked.
+ *
+ * Bulk and interrupt endpoint queues are guaranteed to stop whenever an

+ * that they are not guaranteed to stop for -EREMOTEIO errors.  Queues

- *  IO port access primitives
- *  -------------------------
- *
- * The ARM doesn't have special IO access instructions; all IO is memory
- * mapped.  Note that these are defined to perform little endian accesses
- * only.  Their primary purpose is to access PCI and ISA peripherals.
- *
- * Note that for a big endian machine, this implies that the following
- * big endian mode connectivity is in place, as described by numerious
- * ARM documents:
- *
- *    PCI:  D0-D7   D8-D15 D16-D23 D24-D31
- *    ARM: D24-D31 D16-D23  D8-D15  D0-D7
- *
- * The machine specific io.h include defines __io to translate an "IO"
- * address to a memory address.
- *
- * Note that we prevent GCC re-ordering or caching values in expressions
- * by introducing sequence points into the in*() definitions.  Note that
- * __raw_* do not guarantee this behaviour.

- *
- * pgd_none is 0 to prevernt pmd_alloc() calling __pmd_alloc(). This causes it

- *
- * instead of  mm->pgd->pmd->pte
- * we have     mm->pgdpmd->pte
- *
- * IOW, think of PGD operations and PMD ones as being the same thing, just
- * that PGD stuff deals with the mm_struct side of things, wheras PMD stuff
- * deals with the pte side of things.

- * additionally, we store some bits in the PGD and PTE pointers: 
- * PGDs:
- *   o The lowest (1) bit of the PGD is to determine if it is present or swap.
- *   o The 2nd bit of the PGD is unused and must be zero.
- *   o The top 6 bits of the PGD must be zero. 
- * PTEs:
- *   o The lower 5 bits of a pte are flags. bit 1 is the 'present' flag. The
- *     others determine the pages attributes.
- *
- * the pgd_val, pmd_val, and pte_val macros seem to be private to our code.
- * They get the RAW value of the PGD/PMD/PTE entry, including our flags
- * encoded into the pointers.
- * 
- * The pgd_offset, pmd_offset, and pte_offset macros are used by the kernel,
- * so they shouldnt have our flags attached.

- * What is the most efficient way of loading/storing an unaligned value?
- *
- * That is the subject of this file.  Efficiency here is defined as
- * minimum code size with minimum register usage for the common cases.
- * It is currently not believed that long longs are common, so we
- * trade efficiency for the chars, shorts and longs against the long
- * longs.
- *
- * Current stats with gcc 2.7.2.2 for these functions:
- *
- *	ptrsize	get:	code	regs	put:	code	regs
- *	1		1	1		1	2
- *	2		3	2		3	2
- *	4		7	3		7	3
- *	8		20	6		16	6
- *
- * gcc 2.95.1 seems to code differently:
- *
- *	ptrsize	get:	code	regs	put:	code	regs
- *	1		1	1		1	2
- *	2		3	2		3	2
- *	4		7	4		7	4
- *	8		19	8		15	6
- *
- * which may or may not be more efficient (depending upon whether
- * you can afford the extra registers).  Hopefully the gcc 2.95
- * is inteligent enough to decide if it is better to use the
- * extra register, but evidence so far seems to suggest otherwise.
- *
- * Unfortunately, gcc is not able to optimise the high word
- * out of long long >> 32, or the low word from long long << 32

-/* Core file format: The core file is written in such a way that gdb
-   can understand it and provide useful information to the user (under
-   linux we use the 'trad-core' bfd).  There are quite a number of
-   obstacles to being able to view the contents of the floating point
-   registers, and until these are solved you will not be able to view the
-   contents of them.  Actually, you can read in the core file and look at
-   the contents of the user struct to find out what the floating point
-   registers contain.
-   The actual file contents are as follows:
-   UPAGE: 1 page consisting of a user struct that tells gdb what is present
-   in the file.  Directly after this is a copy of the task_struct, which
-   is currently not used by gdb, but it may come in useful at some point.
-   All of the registers are stored as part of the upage.  The upage should
-   always be only one page.
-   DATA: The data area is stored.  We use current->end_text to
-   current->brk to pick up all of the user variables, plus any memory
-   that may have been malloced.  No attempt is made to determine if a page
-   is demand-zero or if a page is totally unused, we just cover the entire
-   range.  All of the addresses are rounded in such a way that an integral
-   number of pages is written.
-   STACK: We need the stack information in order to get a meaningful
-   backtrace.  We need to write the data from (esp) to
-   current->start_stack, so we round each of these off in order to be able
-   to write an integer number of pages.
-   The minimum core file size is 3 pages, or 12288 bytes.

+ */
+
+/* Some rough guidelines on accessing and updating grant-table entries
+ * in a concurrency-safe manner. For more information, Linux contains a
+ * reference implementation for guest OSes (arch/xen/kernel/grant_table.c).
+ *
+ * NB. WMB is a no-op on current-generation x86 processors. However, a
+ *     compiler barrier will still be required.
+ *
+ * Introducing a valid entry into the grant table:
+ *  1. Write ent->domid.
+ *  2. Write ent->frame:
+ *      GTF_permit_access:   Frame to which access is permitted.
+ *      GTF_accept_transfer: Pseudo-phys frame slot being filled by new
+ *                           frame, or zero if none.
+ *  3. Write memory barrier (WMB).
+ *  4. Write ent->flags, inc. valid type.
+ *
+ * Invalidating an unused GTF_permit_access entry:
+ *  1. flags = ent->flags.
+ *  2. Observe that !(flags & (GTF_reading|GTF_writing)).
+ *  3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ *  NB. No need for WMB as reuse of entry is control-dependent on success of
+ *      step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *
+ * Invalidating an in-use GTF_permit_access entry:
+ *  This cannot be done directly. Request assistance from the domain controller
+ *  which can set a timeout on the use of a grant entry and take necessary
+ *  action. (NB. This is not yet implemented!).
+ *
+ * Invalidating an unused GTF_accept_transfer entry:
+ *  1. flags = ent->flags.
+ *  2. Observe that !(flags & GTF_transfer_committed). [*]
+ *  3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ *  NB. No need for WMB as reuse of entry is control-dependent on success of
+ *      step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *  [*] If GTF_transfer_committed is set then the grant entry is 'committed'.
+ *      The guest must /not/ modify the grant entry until the address of the
+ *      transferred frame is written. It is safe for the guest to spin waiting
+ *      for this to occur (detect by observing GTF_transfer_completed in
+ *      ent->flags).
+ *
+ * Invalidating a committed GTF_accept_transfer entry:
+ *  1. Wait for (ent->flags & GTF_transfer_completed).
+ *
+ * Changing a GTF_permit_access from writable to read-only:
+ *  Use SMP-safe CMPXCHG to set GTF_readonly, while checking !GTF_writing.
+ *
+ * Changing a GTF_permit_access from read-only to writable:
+ *  Use SMP-safe bit-setting instruction.

+	 * Event channels are addressed by a "port index". Each channel is

+	 *     becomes pending while the channel is masked then the 'edge' is lost
+	 *     (i.e., when the channel is unmasked, the guest must manually handle
+	 *     pending notifications as no upcall will be scheduled by Xen).
+	 *
+	 * To expedite scanning of pending notifications, any 0->1 pending
+	 * transition on an unmasked channel causes a corresponding bit in a
+	 * per-vcpu selector word to be set. Each bit in the selector covers a

+ *     not have MFN in our p2m table. Conversely, if the page is ours,
+ *     then we'll have p2m(m2p(MFN))==MFN.
+ * If we detect a special mapping then it doesn't have a 'struct page'.
+ * We force !pfn_valid() by returning an out-of-range pointer.
+ *
+ * NB. These checks require that, for any MFN that is not in our reservation,
+ * there is no PFN such that p2m(PFN) == MFN. Otherwise we can get confused if
+ * we are foreign-mapping the MFN, and the other domain as m2p(MFN) == PFN.
+ * Yikes! Various places must poke in INVALID_P2M_ENTRY for safety.
+ *
+ * NB2. When deliberately mapping foreign pages into the p2m table, you *must*
+ *      use FOREIGN_FRAME(). This will cause pte_pfn() to choke on it, as we
+ *      require. In all the cases we care about, the FOREIGN_FRAME bit is
+ *      masked (e.g., pfn_to_mfn()) so behaviour there is correct.

- * Readahead design.
- *
- * The fields in struct file_ra_state represent the most-recently-executed
- * readahead attempt:
- *
- * start:	Page index at which we started the readahead
- * size:	Number of pages in that read
- *              Together, these form the "current window".
- *              Together, start and size represent the `readahead window'.
- * prev_index:  The page which the readahead algorithm most-recently inspected.
- *              It is mainly used to detect sequential file reading.
- *              If page_cache_readahead sees that it is again being called for
- *              a page which it just looked at, it can return immediately without
- *              making any state changes.
- * offset:      Offset in the prev_index where the last read ended - used for
- *              detection of sequential file reading.
- * ahead_start,
- * ahead_size:  Together, these form the "ahead window".
- * ra_pages:	The externally controlled max readahead for this fd.
- *
- * When readahead is in the off state (size == 0), readahead is disabled.
- * In this state, prev_index is used to detect the resumption of sequential I/O.
- *
- * The readahead code manages two windows - the "current" and the "ahead"
- * windows.  The intent is that while the application is walking the pages
- * in the current window, I/O is underway on the ahead window.  When the
- * current window is fully traversed, it is replaced by the ahead window
- * and the ahead window is invalidated.  When this copying happens, the
- * new current window's pages are probably still locked.  So
- * we submit a new batch of I/O immediately, creating a new ahead window.
- *
- * So:
- *
- *   ----|----------------|----------------|-----
- *       ^start           ^start+size
- *                        ^ahead_start     ^ahead_start+ahead_size
- *
- *         ^ When this page is read, we submit I/O for the
- *           ahead window.
- *
- * A `readahead hit' occurs when a read request is made against a page which is
- * the next sequential page. Ahead window calculations are done only when it
- * is time to submit a new IO.  The code ramps up the size agressively at first,
- * but slow down as it approaches max_readhead.
- *
- * Any seek/ramdom IO will result in readahead being turned off.  It will resume
- * at the first sequential access.
- *
- * There is a special-case: if the first page which the application tries to
- * read happens to be the first page of the file, it is assumed that a linear
- * read is about to happen and the window is immediately set to the initial size
- * based on I/O request size and the max_readahead.
- *
- * This function is to be called for every read request, rather than when
- * it is time to perform readahead.  It is called only once for the entire I/O
- * regardless of size unless readahead is unable to start enough I/O to satisfy
- * the request (I/O request > max_readahead).
- */

  *
- * page_cache_readahead() is the main function.  If performs the adaptive
- * readahead window size management and submits the readahead I/O.
+ * To overlap application thinking time and disk I/O time, we do
+ * `readahead pipelining': Do not wait until the application consumed all
+ * readahead pages and stalled on the missing page at readahead_index;
+ * Instead, submit an asynchronous readahead I/O as soon as there are
+ * only async_size pages left in the readahead window. Normally async_size
+ * will be equal to size, for maximum pipelining.
  *
- * Note that @filp is purely used for passing on to the ->readpage[s]()
- * handler: it may refer to a different file from @mapping (so we may not use
- * @filp->f_mapping or @filp->f_path.dentry->d_inode here).
- * Also, @ra may not be equal to &@filp->f_ra.
+ * In interleaved sequential reads, concurrent streams on the same fd can
+ * be invalidating each other's readahead state. So we flag the new readahead
+ * page at (start+size-async_size) with PG_readahead, and use it as readahead
+ * indicator. The flag won't be set on already cached pages, to avoid the
+ * readahead-for-nothing fuss, saving pointless page cache lookups.
+ *
+ * prev_index tracks the last visited page in the _previous_ read request.
+ * It should be maintained by the caller, and will be used for detecting
+ * small random reads. Note that the readahead algorithm checks loosely
+ * for sequential patterns. Hence interleaved reads might be served as
+ * sequential ones.
+ *
+ * There is a special-case: if the first page which the application tries to
+ * read happens to be the first page of the file, it is assumed that a linear
+ * read is about to happen and the window is immediately set to the initial size

-/*
- *
- * Notes:
- *
- *  1. Much of the OSS buffer allocation, ioctl's, and mmap'ing are
- *     taken, slightly modified or not at all, from the ES1371 driver,
- *     so refer to the credits in es1371.c for those. The rest of the
- *     code (probe, open, read, write, the ISR, etc.) is new.
- *  2. The following support is untested:
- *      * Memory mapping the audio buffers, and the ioctl controls that go
- *        with it.
- *      * S/PDIF output.
- *  3. The following is not supported:
- *      * I2S input.
- *      * legacy audio mode.
- *  4. Support for volume button interrupts is implemented but doesn't
- *     work yet.
- *
- *  Revision history
- *    02.08.2001  0.1   Initial release

+ *
+ * This driver was ported (shamelessly ripped ;) from oss/kahlua.c but I did
+ * mess with it a bit. The chip seems to have to have trouble with full duplex
+ * mode. If we're recording in 8bit 8000kHz, say, and we then attempt to
+ * simultaneously play back audio at 16bit 44100kHz, the device actually plays
+ * back in the same format in which it is capturing. By forcing the chip to
+ * always play/capture in 16/44100, we can let alsa-lib convert the samples and
+ * that way we can hack up some full duplex audio. 
+ * 
+ * XpressAudio(tm) is used on the Cyrix MediaGX (now NatSemi Geode) systems.
+ * The older version (VSA1) provides fairly good soundblaster emulation
+ * although there are a couple of bugs: large DMA buffers break record,
+ * and the MPU event handling seems suspect. VSA2 allows the native driver
+ * to control the AC97 audio engine directly and requires a different driver.
+ *
+ * Thanks to National Semiconductor for providing the needed information
+ * on the XpressAudio(tm) internals.

+ * LIMITATIONS:
+ *	The SSI unit has only one physical data line, so full duplex is

+ *	unit, and its pins are shared with the AC97 unit,  among others.
+ *
+ * FEATURES:
+ *	The SSI features "compressed mode": in this mode it continuously
+ *	streams PCM data over the I2S lines and uses LRCK as a handshake
+ *	signal.  Can be used to send compressed data (AC3/DTS) to a DSP.
+ *	The number of bits sent over the wire in a frame can be adjusted
+ *	and can be independent from the actual sample bit depth. This is
+ *	useful to support TDM mode codecs like the AD1939 which have a
+ *	fixed TDM slot size, regardless of sample resolution.
