-What:		dv1394 (a.k.a. "OHCI-DV I/O support" for FireWire)
-Contact:	linux1394-devel@lists.sourceforge.net
-Description:
-	New application development should use raw1394 + userspace libraries
-	instead, notably libiec61883 which is functionally equivalent.
-
-Users:
-	ffmpeg/libavformat (used by a variety of media players)
-	dvgrab v1.x (replaced by dvgrab2 on top of raw1394 and resp. libraries)

+What:		dv1394 (a.k.a. "OHCI-DV I/O support" for FireWire)
+Date:		May 2010 (scheduled), finally removed in kernel v2.6.37
+Contact:	linux1394-devel@lists.sourceforge.net
+Description:
+	/dev/dv1394/* were character device files, one for each FireWire
+	controller and for NTSC and PAL respectively, from which DV data
+	could be received by read() or transmitted by write().  A few
+	ioctl()s allowed limited control.
+	This special-purpose interface has been superseded by libraw1394 +
+	libiec61883 which are functionally equivalent, support HDV, and
+	transparently work on top of the newer firewire kernel drivers.

+What:		raw1394 (a.k.a. "Raw IEEE1394 I/O support" for FireWire)
+Date:		May 2010 (scheduled), finally removed in kernel v2.6.37
+Contact:	linux1394-devel@lists.sourceforge.net
+Description:
+	/dev/raw1394 was a character device file that allowed low-level
+	access to FireWire buses.  Its major drawbacks were its inability
+	to implement sensible device security policies, and its low level
+	of abstraction that required userspace clients do duplicate much
+	of the kernel's ieee1394 core functionality.
+	Replaced by /dev/fw*, i.e. the <linux/firewire-cdev.h> ABI of
+	firewire-core.
+
+Users:
+	libraw1394 (works with firewire-cdev too, transparent to library ABI

-What:		legacy isochronous ABI of raw1394 (1st generation iso ABI)
-Date:		June 2007 (scheduled), removed in kernel v2.6.23
-Contact:	linux1394-devel@lists.sourceforge.net
-Description:
-	The two request types RAW1394_REQ_ISO_SEND, RAW1394_REQ_ISO_LISTEN have
-	been deprecated for quite some time.  They are very inefficient as they
-	come with high interrupt load and several layers of callbacks for each
-	packet.  Because of these deficiencies, the video1394 and dv1394 drivers
-	and the 3rd-generation isochronous ABI in raw1394 (rawiso) were created.
-
-Users:
-	libraw1394 users via the long deprecated API raw1394_iso_write,
-	raw1394_start_iso_write, raw1394_start_iso_rcv, raw1394_stop_iso_rcv
-
-	libdc1394, which optionally uses these old libraw1394 calls
-	alternatively to the more efficient video1394 ABI

+Description:
+	/dev/video1394/* were character device files, one for each FireWire
+	controller, which were used for isochronous I/O.  It was added as an
+	alternative to raw1394's isochronous I/O functionality which had
+	performance issues in its first generation.  Any video1394 user had
+	to use raw1394 + libraw1394 too because video1394 did not provide
+	asynchronous I/O for device discovery and configuration.

+[Configure viafb via /proc]
+---------------------------
+    The following files exist in /proc/viafb
+
+    supported_output_devices
+
+        This read-only file contains a full ',' seperated list containing all
+        output devices that could be available on your platform. It is likely
+        that not all of those have a connector on your hardware but it should
+        provide a good starting point to figure out which of those names match
+        a real connector.
+        Example:
+        # cat /proc/viafb/supported_output_devices
+
+    iga1/output_devices
+    iga2/output_devices
+
+        These two files are readable and writable. iga1 and iga2 are the two
+        independent units that produce the screen image. Those images can be
+        forwarded to one or more output devices. Reading those files is a way
+        to query which output devices are currently used by an iga.
+        Example:
+        # cat /proc/viafb/iga1/output_devices
+        If there are no output devices printed the output of this iga is lost.
+        This can happen for example if only one (the other) iga is used.
+        Writing to these files allows adjusting the output devices during
+        runtime. One can add new devices, remove existing ones or switch
+        between igas. Essentially you can write a ',' seperated list of device
+        names (or a single one) in the same format as the output to those
+        files. You can add a '+' or '-' as a prefix allowing simple addition
+        and removal of devices. So a prefix '+' adds the devices from your list
+        to the already existing ones, '-' removes the listed devices from the
+        existing ones and if no prefix is given it replaces all existing ones
+        with the listed ones. If you remove devices they are expected to turn
+        off. If you add devices that are already part of the other iga they are
+        removed there and added to the new one.
+        Examples:
+        Add CRT as output device to iga1
+        # echo +CRT > /proc/viafb/iga1/output_devices
+
+        Remove (turn off) DVP1 and LVDS1 as output devices of iga2
+        # echo -DVP1,LVDS1 > /proc/viafb/iga2/output_devices
+
+        Replace all iga1 output devices by CRT
+        # echo CRT > /proc/viafb/iga1/output_devices

+translate user and group names into ids.  Part of this translation involves
+performing an upcall to userspace to request the information.  Id mapper will
+user request-key to perform this upcall and cache the result.  The program
+/usr/sbin/nfs.idmap should be called by request-key, and will perform the
+translation and initialize a key with the resulting information.
+
+ NFS_USE_NEW_IDMAPPER must be selected when configuring the kernel to use this
+ feature.
+
+===========
+Configuring
+===========
+The file /etc/request-key.conf will need to be modified so /sbin/request-key can
+direct the upcall.  The following line should be added:
+
+#OP	TYPE	DESCRIPTION	CALLOUT INFO	PROGRAM ARG1 ARG2 ARG3 ...
+#======	=======	===============	===============	===============================
+create	id_resolver	*	*		/usr/sbin/nfs.idmap %k %d 600
+
+This will direct all id_resolver requests to the program /usr/sbin/nfs.idmap.
+The last parameter, 600, defines how many seconds into the future the key will
+expire.  This parameter is optional for /usr/sbin/nfs.idmap.  When the timeout
+is not specified, nfs.idmap will default to 600 seconds.
+
+id mapper uses for key descriptions:
+	  uid:  Find the UID for the given user
+	  gid:  Find the GID for the given group
+	 user:  Find the user  name for the given UID
+	group:  Find the group name for the given GID
+
+You can handle any of these individually, rather than using the generic upcall
+program.  If you would like to use your own program for a uid lookup then you
+would edit your request-key.conf so it look similar to this:
+
+#OP	TYPE	DESCRIPTION	CALLOUT INFO	PROGRAM ARG1 ARG2 ARG3 ...
+#======	=======	===============	===============	===============================
+create	id_resolver	uid:*	*		/some/other/program %k %d 600
+create	id_resolver	*	*		/usr/sbin/nfs.idmap %k %d 600
+
+Notice that the new line was added above the line for the generic program.
+request-key will find the first matching line and corresponding program.  In
+this case, /some/other/program will handle all uid lookups and
+/usr/sbin/nfs.idmap will handle gid, user, and group lookups.
+
+See <file:Documentation/keys-request-keys.txt> for more information about the
+request-key function.
+
+
+=========
+nfs.idmap
+=========
+nfs.idmap is designed to be called by request-key, and should not be run "by
+hand".  This program takes two arguments, a serialized key and a key
+description.  The serialized key is first converted into a key_serial_t, and
+then passed as an argument to keyctl_instantiate (both are part of keyutils.h).
+
+The actual lookups are performed by functions found in nfsidmap.h.  nfs.idmap
+determines the correct function to call by looking at the first part of the
+description string.  For example, a uid lookup description will appear as
+"uid:user@domain".
+
+nfs.idmap will return 0 if the key was instantiated, and non-zero otherwise.

+Reference counting in pnfs:
+==========================
+
+The are several inter-related caches.  We have layouts which can
+reference multiple devices, each of which can reference multiple data servers.
+Each data server can be referenced by multiple devices.  Each device
+can be referenced by multiple layouts.  To keep all of this straight,
+we need to reference count.
+
+
+struct pnfs_layout_hdr
+----------------------
+The on-the-wire command LAYOUTGET corresponds to struct
+pnfs_layout_segment, usually referred to by the variable name lseg.
+Each nfs_inode may hold a pointer to a cache of of these layout
+segments in nfsi->layout, of type struct pnfs_layout_hdr.
+
+We reference the header for the inode pointing to it, across each
+outstanding RPC call that references it (LAYOUTGET, LAYOUTRETURN,
+LAYOUTCOMMIT), and for each lseg held within.
+
+Each header is also (when non-empty) put on a list associated with
+struct nfs_client (cl_layouts).  Being put on this list does not bump
+the reference count, as the layout is kept around by the lseg that
+keeps it in the list.
+
+deviceid_cache
+--------------
+lsegs reference device ids, which are resolved per nfs_client and
+layout driver type.  The device ids are held in a RCU cache (struct
+nfs4_deviceid_cache).  The cache itself is referenced across each
+mount.  The entries (struct nfs4_deviceid) themselves are held across
+the lifetime of each lseg referencing them.
+
+RCU is used because the deviceid is basically a write once, read many
+data structure.  The hlist size of 32 buckets needs better
+justification, but seems reasonable given that we can have multiple
+deviceid's per filesystem, and multiple filesystems per nfs_client.
+
+The hash code is copied from the nfsd code base.  A discussion of
+hashing and variations of this algorithm can be found at:
+http://groups.google.com/group/comp.lang.c/browse_thread/thread/9522965e2b8d3809
+
+data server cache
+-----------------
+file driver devices refer to data servers, which are kept in a module
+level cache.  Its reference is held over the lifetime of the deviceid
+pointing to it.

+Description
+-----------
+
+The LTC4261/LTC4261-2 negative voltage Hot Swap controllers allow a board
+to be safely inserted and removed from a live backplane.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for LTC4261 devices, since there is no register
+which can be safely used to identify the chip. You will have to instantiate
+the devices explicitly.
+
+Example: the following will load the driver for an LTC4261 at address 0x10
+on I2C bus #1:
+$ modprobe ltc4261
+$ echo ltc4261 0x10 > /sys/bus/i2c/devices/i2c-1/new_device
+
+
+Sysfs entries
+-------------
+
+Voltage readings provided by this driver are reported as obtained from the ADC
+registers. If a set of voltage divider resistors is installed, calculate the
+real voltage by multiplying the reported value with (R1+R2)/R2, where R1 is the
+value of the divider resistor against the measured voltage and R2 is the value
+of the divider resistor against Ground.
+
+Current reading provided by this driver is reported as obtained from the ADC
+Current Sense register. The reported value assumes that a 1 mOhm sense resistor
+is installed. If a different sense resistor is installed, calculate the real
+current by dividing the reported value by the sense resistor value in mOhm.
+
+The chip has two voltage sensors, but only one set of voltage alarm status bits.
+In many many designs, those alarms are associated with the ADIN2 sensor, due to
+the proximity of the ADIN2 pin to the OV pin. ADIN2 is, however, not available
+on all chip variants. To ensure that the alarm condition is reported to the user,
+report it with both voltage sensors.

+N-Trig touchscreen Driver
+-------------------------
+	Copyright (c) 2008-2010 Rafi Rubin <rafi@seas.upenn.edu>
+	Copyright (c) 2009-2010 Stephane Chatty
+
+This driver provides support for N-Trig pen and multi-touch sensors.  Single
+and multi-touch events are translated to the appropriate protocols for
+the hid and input systems.  Pen events are sufficiently hid compliant and
+are left to the hid core.  The driver also provides additional filtering
+and utility functions accessible with sysfs and module parameters.
+
+This driver has been reported to work properly with multiple N-Trig devices
+attached.
+
+
+Parameters
+----------
+
+Note: values set at load time are global and will apply to all applicable
+devices.  Adjusting parameters with sysfs will override the load time values,
+but only for that one device.
+
+The following parameters are used to configure filters to reduce noise:
+
+activate_slack		number of fingers to ignore before processing events
+
+activation_height	size threshold to activate immediately
+activation_width
+
+min_height		size threshold bellow which fingers are ignored
+min_width		both to decide activation and during activity
+
+deactivate_slack	the number of "no contact" frames to ignore before
+			propagating the end of activity events
+
+When the last finger is removed from the device, it sends a number of empty
+frames.  By holding off on deactivation for a few frames we can tolerate false
+erroneous disconnects, where the sensor may mistakenly not detect a finger that
+is still present.  Thus deactivate_slack addresses problems where a users might
+see breaks in lines during drawing, or drop an object during a long drag.
+
+
+Additional sysfs items
+----------------------
+
+These nodes just provide easy access to the ranges reported by the device.
+sensor_logical_height	the range for positions reported during activity
+sensor_logical_width
+
+sensor_physical_height	internal ranges not used for normal events but
+sensor_physical_width	useful for tuning
+
+All N-Trig devices with product id of 1 report events in the ranges of
+X: 0-9600
+Y: 0-7200
+However not all of these devices have the same physical dimensions.  Most
+seem to be 12" sensors (Dell Latitude XT and XT2 and the HP TX2), and
+at least one model (Dell Studio 17) has a 17" sensor.  The ratio of physical
+to logical sizes is used to adjust the size based filter parameters.
+
+
+Filtering
+---------
+
+With the release of the early multi-touch firmwares it became increasingly
+obvious that these sensors were prone to erroneous events.  Users reported
+seeing both inappropriately dropped contact and ghosts, contacts reported
+where no finger was actually touching the screen.
+
+Deactivation slack helps prevent dropped contact for single touch use, but does
+not address the problem of dropping one of more contacts while other contacts
+are still active.  Drops in the multi-touch context require additional
+processing and should be handled in tandem with tacking.
+
+As observed ghost contacts are similar to actual use of the sensor, but they
+seem to have different profiles.  Ghost activity typically shows up as small
+short lived touches.  As such, I assume that the longer the continuous stream
+of events the more likely those events are from a real contact, and that the
+larger the size of each contact the more likely it is real.  Balancing the
+goals of preventing ghosts and accepting real events quickly (to minimize
+user observable latency), the filter accumulates confidence for incoming
+events until it hits thresholds and begins propagating.  In the interest in
+minimizing stored state as well as the cost of operations to make a decision,
+I've kept that decision simple.
+
+Time is measured in terms of the number of fingers reported, not frames since
+the probability of multiple simultaneous ghosts is expected to drop off
+dramatically with increasing numbers.  Rather than accumulate weight as a
+function of size, I just use it as a binary threshold.  A sufficiently large
+contact immediately overrides the waiting period and leads to activation.
+
+Setting the activation size thresholds to large values will result in deciding
+primarily on activation slack.  If you see longer lived ghosts, turning up the
+activation slack while reducing the size thresholds may suffice to eliminate
+the ghosts while keeping the screen quite responsive to firm taps.
+
+Contacts continue to be filtered with min_height and min_width even after
+the initial activation filter is satisfied.  The intent is to provide
+a mechanism for filtering out ghosts in the form of an extra finger while
+you actually are using the screen.  In practice this sort of ghost has
+been far less problematic or relatively rare and I've left the defaults
+set to 0 for both parameters, effectively turning off that filter.
+
+I don't know what the optimal values are for these filters.  If the defaults
+don't work for you, please play with the parameters.  If you do find other
+values more comfortable, I would appreciate feedback.
+
+The calibration of these devices does drift over time.  If ghosts or contact
+dropping worsen and interfere with the normal usage of your device, try
+recalibrating it.
+
+
+Calibration
+-----------
+
+The N-Trig windows tools provide calibration and testing routines.  Also an
+unofficial unsupported set of user space tools including a calibrator is
+available at:
+http://code.launchpad.net/~rafi-seas/+junk/ntrig_calib
+
+
+Tracking
+--------
+
+As of yet, all tested N-Trig firmwares do not track fingers.  When multiple
+contacts are active they seem to be sorted primarily by Y position.

+The PPC KVM paravirtual interface
+=================================
+
+The basic execution principle by which KVM on PowerPC works is to run all kernel
+space code in PR=1 which is user space. This way we trap all privileged
+instructions and can emulate them accordingly.
+
+Unfortunately that is also the downfall. There are quite some privileged
+instructions that needlessly return us to the hypervisor even though they
+could be handled differently.
+
+This is what the PPC PV interface helps with. It takes privileged instructions
+and transforms them into unprivileged ones with some help from the hypervisor.
+This cuts down virtualization costs by about 50% on some of my benchmarks.
+
+The code for that interface can be found in arch/powerpc/kernel/kvm*
+
+Querying for existence
+======================
+
+To find out if we're running on KVM or not, we leverage the device tree. When
+Linux is running on KVM, a node /hypervisor exists. That node contains a
+compatible property with the value "linux,kvm".
+
+Once you determined you're running under a PV capable KVM, you can now use
+hypercalls as described below.
+
+KVM hypercalls
+==============
+
+Inside the device tree's /hypervisor node there's a property called
+'hypercall-instructions'. This property contains at most 4 opcodes that make
+up the hypercall. To call a hypercall, just call these instructions.
+
+The parameters are as follows:
+
+	Register	IN			OUT
+
+	r0		-			volatile
+	r3		1st parameter		Return code
+	r4		2nd parameter		1st output value
+	r5		3rd parameter		2nd output value
+	r6		4th parameter		3rd output value
+	r7		5th parameter		4th output value
+	r8		6th parameter		5th output value
+	r9		7th parameter		6th output value
+	r10		8th parameter		7th output value
+	r11		hypercall number	8th output value
+	r12		-			volatile
+
+Hypercall definitions are shared in generic code, so the same hypercall numbers
+apply for x86 and powerpc alike with the exception that each KVM hypercall
+also needs to be ORed with the KVM vendor code which is (42 << 16).
+
+Return codes can be as follows:
+
+	Code		Meaning
+
+	0		Success
+	12		Hypercall not implemented
+	<0		Error
+
+The magic page
+==============
+
+To enable communication between the hypervisor and guest there is a new shared
+page that contains parts of supervisor visible register state. The guest can
+map this shared page using the KVM hypercall KVM_HC_PPC_MAP_MAGIC_PAGE.
+
+With this hypercall issued the guest always gets the magic page mapped at the
+desired location in effective and physical address space. For now, we always
+map the page to -4096. This way we can access it using absolute load and store
+functions. The following instruction reads the first field of the magic page:
+
+	ld	rX, -4096(0)
+
+The interface is designed to be extensible should there be need later to add
+additional registers to the magic page. If you add fields to the magic page,
+also define a new hypercall feature to indicate that the host can give you more
+registers. Only if the host supports the additional features, make use of them.
+
+The magic page has the following layout as described in
+arch/powerpc/include/asm/kvm_para.h:
+
+struct kvm_vcpu_arch_shared {
+	__u64 scratch1;
+	__u64 scratch2;
+	__u64 scratch3;
+	__u64 critical;		/* Guest may not get interrupts if == r1 */
+	__u64 sprg0;
+	__u64 sprg1;
+	__u64 sprg2;
+	__u64 sprg3;
+	__u64 srr0;
+	__u64 srr1;
+	__u64 dar;
+	__u64 msr;
+	__u32 dsisr;
+	__u32 int_pending;	/* Tells the guest if we have an interrupt */
+};
+
+Additions to the page must only occur at the end. Struct fields are always 32
+or 64 bit aligned, depending on them being 32 or 64 bit wide respectively.
+
+Magic page features
+===================
+
+When mapping the magic page using the KVM hypercall KVM_HC_PPC_MAP_MAGIC_PAGE,
+a second return value is passed to the guest. This second return value contains
+a bitmap of available features inside the magic page.
+
+The following enhancements to the magic page are currently available:
+
+  KVM_MAGIC_FEAT_SR		Maps SR registers r/w in the magic page
+
+For enhanced features in the magic page, please check for the existence of the
+feature before using them!
+
+MSR bits
+========
+
+The MSR contains bits that require hypervisor intervention and bits that do
+not require direct hypervisor intervention because they only get interpreted
+when entering the guest or don't have any impact on the hypervisor's behavior.
+
+The following bits are safe to be set inside the guest:
+
+  MSR_EE
+  MSR_RI
+  MSR_CR
+  MSR_ME
+
+If any other bit changes in the MSR, please still use mtmsr(d).
+
+Patched instructions
+====================
+
+The "ld" and "std" instructions are transormed to "lwz" and "stw" instructions
+respectively on 32 bit systems with an added offset of 4 to accomodate for big
+endianness.
+
+The following is a list of mapping the Linux kernel performs when running as
+guest. Implementing any of those mappings is optional, as the instruction traps
+also act on the shared page. So calling privileged instructions still works as
+before.

+
+
+Some instructions require more logic to determine what's going on than a load
+or store instruction can deliver. To enable patching of those, we keep some
+RAM around where we can live translate instructions to. What happens is the
+following:
+
+	1) copy emulation code to memory
+	2) patch that code to fit the emulated instruction
+	3) patch that code to return to the original pc + 4
+	4) patch the original instruction to branch to the new code
+
+That way we can inject an arbitrary amount of code as replacement for a single
+instruction. This allows us to check for pending interrupts when setting EE=1
+for example.

+	Timekeeping Virtualization for X86-Based Architectures

+1) Overview
+2) Timing Devices
+3) TSC Hardware
+4) Virtualization Problems
+
+=========================================================================
+
+1) Overview
+
+One of the most complicated parts of the X86 platform, and specifically,
+the virtualization of this platform is the plethora of timing devices available
+and the complexity of emulating those devices.  In addition, virtualization of
+time introduces a new set of challenges because it introduces a multiplexed
+division of time beyond the control of the guest CPU.
+
+First, we will describe the various timekeeping hardware available, then
+present some of the problems which arise and solutions available, giving
+specific recommendations for certain classes of KVM guests.
+
+The purpose of this document is to collect data and information relevant to
+timekeeping which may be difficult to find elsewhere, specifically,
+information relevant to KVM and hardware-based virtualization.
+
+=========================================================================
+
+2) Timing Devices
+
+First we discuss the basic hardware devices available.  TSC and the related
+KVM clock are special enough to warrant a full exposition and are described in
+the following section.
+
+2.1) i8254 - PIT
+
+One of the first timer devices available is the programmable interrupt timer,
+or PIT.  The PIT has a fixed frequency 1.193182 MHz base clock and three
+channels which can be programmed to deliver periodic or one-shot interrupts.
+These three channels can be configured in different modes and have individual
+counters.  Channel 1 and 2 were not available for general use in the original
+IBM PC, and historically were connected to control RAM refresh and the PC
+speaker.  Now the PIT is typically integrated as part of an emulated chipset
+and a separate physical PIT is not used.
+
+The PIT uses I/O ports 0x40 - 0x43.  Access to the 16-bit counters is done
+using single or multiple byte access to the I/O ports.  There are 6 modes
+available, but not all modes are available to all timers, as only timer 2
+has a connected gate input, required for modes 1 and 5.  The gate line is
+controlled by port 61h, bit 0, as illustrated in the following diagram.
+

+Port 61h, bit 1 -----------------------------------/
+
+The timer modes are now described.
+
+Mode 0: Single Timeout.   This is a one-shot software timeout that counts down
+ when the gate is high (always true for timers 0 and 1).  When the count
+ reaches zero, the output goes high.
+
+Mode 1: Triggered One-shot.  The output is intially set high.  When the gate
+ line is set high, a countdown is initiated (which does not stop if the gate is
+ lowered), during which the output is set low.  When the count reaches zero,
+ the output goes high.
+
+Mode 2: Rate Generator.  The output is initially set high.  When the countdown
+ reaches 1, the output goes low for one count and then returns high.  The value
+ is reloaded and the countdown automatically resumes.  If the gate line goes
+ low, the count is halted.  If the output is low when the gate is lowered, the
+ output automatically goes high (this only affects timer 2).
+
+Mode 3: Square Wave.   This generates a high / low square wave.  The count
+ determines the length of the pulse, which alternates between high and low
+ when zero is reached.  The count only proceeds when gate is high and is
+ automatically reloaded on reaching zero.  The count is decremented twice at
+ each clock to generate a full high / low cycle at the full periodic rate.
+ If the count is even, the clock remains high for N/2 counts and low for N/2
+ counts; if the clock is odd, the clock is high for (N+1)/2 counts and low
+ for (N-1)/2 counts.  Only even values are latched by the counter, so odd
+ values are not observed when reading.  This is the intended mode for timer 2,
+ which generates sine-like tones by low-pass filtering the square wave output.
+
+Mode 4: Software Strobe.  After programming this mode and loading the counter,
+ the output remains high until the counter reaches zero.  Then the output
+ goes low for 1 clock cycle and returns high.  The counter is not reloaded.
+ Counting only occurs when gate is high.
+
+Mode 5: Hardware Strobe.  After programming and loading the counter, the
+ output remains high.  When the gate is raised, a countdown is initiated
+ (which does not stop if the gate is lowered).  When the counter reaches zero,
+ the output goes low for 1 clock cycle and then returns high.  The counter is
+ not reloaded.
+
+In addition to normal binary counting, the PIT supports BCD counting.  The
+command port, 0x43 is used to set the counter and mode for each of the three
+timers.
+
+PIT commands, issued to port 0x43, using the following bit encoding:
+
+Bit 7-4: Command (See table below)
+Bit 3-1: Mode (000 = Mode 0, 101 = Mode 5, 11X = undefined)
+Bit 0  : Binary (0) / BCD (1)

+
+2.2) RTC
+
+The second device which was available in the original PC was the MC146818 real
+time clock.  The original device is now obsolete, and usually emulated by the
+system chipset, sometimes by an HPET and some frankenstein IRQ routing.
+
+The RTC is accessed through CMOS variables, which uses an index register to
+control which bytes are read.  Since there is only one index register, read
+of the CMOS and read of the RTC require lock protection (in addition, it is
+dangerous to allow userspace utilities such as hwclock to have direct RTC
+access, as they could corrupt kernel reads and writes of CMOS memory).
+
+The RTC generates an interrupt which is usually routed to IRQ 8.  The interrupt
+can function as a periodic timer, an additional once a day alarm, and can issue
+interrupts after an update of the CMOS registers by the MC146818 is complete.
+The type of interrupt is signalled in the RTC status registers.
+
+The RTC will update the current time fields by battery power even while the
+system is off.  The current time fields should not be read while an update is
+in progress, as indicated in the status register.
+
+The clock uses a 32.768kHz crystal, so bits 6-4 of register A should be
+programmed to a 32kHz divider if the RTC is to count seconds.
+
+This is the RAM map originally used for the RTC/CMOS:

+
+2.3) APIC
+
+On Pentium and later processors, an on-board timer is available to each CPU
+as part of the Advanced Programmable Interrupt Controller.  The APIC is
+accessed through memory-mapped registers and provides interrupt service to each
+CPU, used for IPIs and local timer interrupts.
+
+Although in theory the APIC is a safe and stable source for local interrupts,
+in practice, many bugs and glitches have occurred due to the special nature of
+the APIC CPU-local memory-mapped hardware.  Beware that CPU errata may affect
+the use of the APIC and that workarounds may be required.  In addition, some of
+these workarounds pose unique constraints for virtualization - requiring either
+extra overhead incurred from extra reads of memory-mapped I/O or additional
+functionality that may be more computationally expensive to implement.
+
+Since the APIC is documented quite well in the Intel and AMD manuals, we will
+avoid repetition of the detail here.  It should be pointed out that the APIC
+timer is programmed through the LVT (local vector timer) register, is capable
+of one-shot or periodic operation, and is based on the bus clock divided down
+by the programmable divider register.
+
+2.4) HPET
+
+HPET is quite complex, and was originally intended to replace the PIT / RTC
+support of the X86 PC.  It remains to be seen whether that will be the case, as
+the de facto standard of PC hardware is to emulate these older devices.  Some
+systems designated as legacy free may support only the HPET as a hardware timer
+device.
+
+The HPET spec is rather loose and vague, requiring at least 3 hardware timers,
+but allowing implementation freedom to support many more.  It also imposes no
+fixed rate on the timer frequency, but does impose some extremal values on
+frequency, error and slew.
+
+In general, the HPET is recommended as a high precision (compared to PIT /RTC)
+time source which is independent of local variation (as there is only one HPET
+in any given system).  The HPET is also memory-mapped, and its presence is
+indicated through ACPI tables by the BIOS.
+
+Detailed specification of the HPET is beyond the current scope of this
+document, as it is also very well documented elsewhere.
+
+2.5) Offboard Timers
+
+Several cards, both proprietary (watchdog boards) and commonplace (e1000) have
+timing chips built into the cards which may have registers which are accessible
+to kernel or user drivers.  To the author's knowledge, using these to generate
+a clocksource for a Linux or other kernel has not yet been attempted and is in
+general frowned upon as not playing by the agreed rules of the game.  Such a
+timer device would require additional support to be virtualized properly and is
+not considered important at this time as no known operating system does this.
+
+=========================================================================
+
+3) TSC Hardware
+
+The TSC or time stamp counter is relatively simple in theory; it counts
+instruction cycles issued by the processor, which can be used as a measure of
+time.  In practice, due to a number of problems, it is the most complicated
+timekeeping device to use.
+
+The TSC is represented internally as a 64-bit MSR which can be read with the
+RDMSR, RDTSC, or RDTSCP (when available) instructions.  In the past, hardware
+limitations made it possible to write the TSC, but generally on old hardware it
+was only possible to write the low 32-bits of the 64-bit counter, and the upper
+32-bits of the counter were cleared.  Now, however, on Intel processors family
+0Fh, for models 3, 4 and 6, and family 06h, models e and f, this restriction
+has been lifted and all 64-bits are writable.  On AMD systems, the ability to
+write the TSC MSR is not an architectural guarantee.
+
+The TSC is accessible from CPL-0 and conditionally, for CPL > 0 software by
+means of the CR4.TSD bit, which when enabled, disables CPL > 0 TSC access.
+
+Some vendors have implemented an additional instruction, RDTSCP, which returns
+atomically not just the TSC, but an indicator which corresponds to the
+processor number.  This can be used to index into an array of TSC variables to
+determine offset information in SMP systems where TSCs are not synchronized.
+The presence of this instruction must be determined by consulting CPUID feature
+bits.
+
+Both VMX and SVM provide extension fields in the virtualization hardware which
+allows the guest visible TSC to be offset by a constant.  Newer implementations
+promise to allow the TSC to additionally be scaled, but this hardware is not
+yet widely available.
+
+3.1) TSC synchronization
+
+The TSC is a CPU-local clock in most implementations.  This means, on SMP
+platforms, the TSCs of different CPUs may start at different times depending
+on when the CPUs are powered on.  Generally, CPUs on the same die will share
+the same clock, however, this is not always the case.
+
+The BIOS may attempt to resynchronize the TSCs during the poweron process and
+the operating system or other system software may attempt to do this as well.
+Several hardware limitations make the problem worse - if it is not possible to
+write the full 64-bits of the TSC, it may be impossible to match the TSC in
+newly arriving CPUs to that of the rest of the system, resulting in
+unsynchronized TSCs.  This may be done by BIOS or system software, but in
+practice, getting a perfectly synchronized TSC will not be possible unless all
+values are read from the same clock, which generally only is possible on single
+socket systems or those with special hardware support.
+
+3.2) TSC and CPU hotplug
+
+As touched on already, CPUs which arrive later than the boot time of the system
+may not have a TSC value that is synchronized with the rest of the system.
+Either system software, BIOS, or SMM code may actually try to establish the TSC
+to a value matching the rest of the system, but a perfect match is usually not
+a guarantee.  This can have the effect of bringing a system from a state where
+TSC is synchronized back to a state where TSC synchronization flaws, however
+small, may be exposed to the OS and any virtualization environment.
+
+3.3) TSC and multi-socket / NUMA
+
+Multi-socket systems, especially large multi-socket systems are likely to have
+individual clocksources rather than a single, universally distributed clock.
+Since these clocks are driven by different crystals, they will not have
+perfectly matched frequency, and temperature and electrical variations will
+cause the CPU clocks, and thus the TSCs to drift over time.  Depending on the
+exact clock and bus design, the drift may or may not be fixed in absolute
+error, and may accumulate over time.
+
+In addition, very large systems may deliberately slew the clocks of individual
+cores.  This technique, known as spread-spectrum clocking, reduces EMI at the
+clock frequency and harmonics of it, which may be required to pass FCC
+standards for telecommunications and computer equipment.
+
+It is recommended not to trust the TSCs to remain synchronized on NUMA or
+multiple socket systems for these reasons.
+
+3.4) TSC and C-states
+
+C-states, or idling states of the processor, especially C1E and deeper sleep
+states may be problematic for TSC as well.  The TSC may stop advancing in such
+a state, resulting in a TSC which is behind that of other CPUs when execution
+is resumed.  Such CPUs must be detected and flagged by the operating system
+based on CPU and chipset identifications.
+
+The TSC in such a case may be corrected by catching it up to a known external
+clocksource.
+
+3.5) TSC frequency change / P-states
+
+To make things slightly more interesting, some CPUs may change frequency.  They
+may or may not run the TSC at the same rate, and because the frequency change
+may be staggered or slewed, at some points in time, the TSC rate may not be
+known other than falling within a range of values.  In this case, the TSC will
+not be a stable time source, and must be calibrated against a known, stable,
+external clock to be a usable source of time.
+
+Whether the TSC runs at a constant rate or scales with the P-state is model
+dependent and must be determined by inspecting CPUID, chipset or vendor
+specific MSR fields.
+
+In addition, some vendors have known bugs where the P-state is actually
+compensated for properly during normal operation, but when the processor is
+inactive, the P-state may be raised temporarily to service cache misses from
+other processors.  In such cases, the TSC on halted CPUs could advance faster
+than that of non-halted processors.  AMD Turion processors are known to have
+this problem.
+
+3.6) TSC and STPCLK / T-states
+
+External signals given to the processor may also have the effect of stopping
+the TSC.  This is typically done for thermal emergency power control to prevent
+an overheating condition, and typically, there is no way to detect that this
+condition has happened.
+
+3.7) TSC virtualization - VMX
+
+VMX provides conditional trapping of RDTSC, RDMSR, WRMSR and RDTSCP
+instructions, which is enough for full virtualization of TSC in any manner.  In
+addition, VMX allows passing through the host TSC plus an additional TSC_OFFSET
+field specified in the VMCS.  Special instructions must be used to read and
+write the VMCS field.
+
+3.8) TSC virtualization - SVM
+
+SVM provides conditional trapping of RDTSC, RDMSR, WRMSR and RDTSCP
+instructions, which is enough for full virtualization of TSC in any manner.  In
+addition, SVM allows passing through the host TSC plus an additional offset
+field specified in the SVM control block.
+
+3.9) TSC feature bits in Linux
+
+In summary, there is no way to guarantee the TSC remains in perfect
+synchronization unless it is explicitly guaranteed by the architecture.  Even
+if so, the TSCs in multi-sockets or NUMA systems may still run independently
+despite being locally consistent.
+
+The following feature bits are used by Linux to signal various TSC attributes,
+but they can only be taken to be meaningful for UP or single node systems.
+
+X86_FEATURE_TSC 		: The TSC is available in hardware
+X86_FEATURE_RDTSCP		: The RDTSCP instruction is available
+X86_FEATURE_CONSTANT_TSC 	: The TSC rate is unchanged with P-states
+X86_FEATURE_NONSTOP_TSC		: The TSC does not stop in C-states
+X86_FEATURE_TSC_RELIABLE	: TSC sync checks are skipped (VMware)
+
+4) Virtualization Problems
+
+Timekeeping is especially problematic for virtualization because a number of
+challenges arise.  The most obvious problem is that time is now shared between
+the host and, potentially, a number of virtual machines.  Thus the virtual
+operating system does not run with 100% usage of the CPU, despite the fact that
+it may very well make that assumption.  It may expect it to remain true to very
+exacting bounds when interrupt sources are disabled, but in reality only its
+virtual interrupt sources are disabled, and the machine may still be preempted
+at any time.  This causes problems as the passage of real time, the injection
+of machine interrupts and the associated clock sources are no longer completely
+synchronized with real time.
+
+This same problem can occur on native harware to a degree, as SMM mode may
+steal cycles from the naturally on X86 systems when SMM mode is used by the
+BIOS, but not in such an extreme fashion.  However, the fact that SMM mode may
+cause similar problems to virtualization makes it a good justification for
+solving many of these problems on bare metal.
+
+4.1) Interrupt clocking
+
+One of the most immediate problems that occurs with legacy operating systems
+is that the system timekeeping routines are often designed to keep track of
+time by counting periodic interrupts.  These interrupts may come from the PIT
+or the RTC, but the problem is the same: the host virtualization engine may not
+be able to deliver the proper number of interrupts per second, and so guest
+time may fall behind.  This is especially problematic if a high interrupt rate
+is selected, such as 1000 HZ, which is unfortunately the default for many Linux
+guests.
+
+There are three approaches to solving this problem; first, it may be possible
+to simply ignore it.  Guests which have a separate time source for tracking
+'wall clock' or 'real time' may not need any adjustment of their interrupts to
+maintain proper time.  If this is not sufficient, it may be necessary to inject
+additional interrupts into the guest in order to increase the effective
+interrupt rate.  This approach leads to complications in extreme conditions,
+where host load or guest lag is too much to compensate for, and thus another
+solution to the problem has risen: the guest may need to become aware of lost
+ticks and compensate for them internally.  Although promising in theory, the
+implementation of this policy in Linux has been extremely error prone, and a
+number of buggy variants of lost tick compensation are distributed across
+commonly used Linux systems.
+
+Windows uses periodic RTC clocking as a means of keeping time internally, and
+thus requires interrupt slewing to keep proper time.  It does use a low enough
+rate (ed: is it 18.2 Hz?) however that it has not yet been a problem in
+practice.
+
+4.2) TSC sampling and serialization
+
+As the highest precision time source available, the cycle counter of the CPU
+has aroused much interest from developers.  As explained above, this timer has
+many problems unique to its nature as a local, potentially unstable and
+potentially unsynchronized source.  One issue which is not unique to the TSC,
+but is highlighted because of its very precise nature is sampling delay.  By
+definition, the counter, once read is already old.  However, it is also
+possible for the counter to be read ahead of the actual use of the result.
+This is a consequence of the superscalar execution of the instruction stream,
+which may execute instructions out of order.  Such execution is called
+non-serialized.  Forcing serialized execution is necessary for precise
+measurement with the TSC, and requires a serializing instruction, such as CPUID
+or an MSR read.
+
+Since CPUID may actually be virtualized by a trap and emulate mechanism, this
+serialization can pose a performance issue for hardware virtualization.  An
+accurate time stamp counter reading may therefore not always be available, and
+it may be necessary for an implementation to guard against "backwards" reads of
+the TSC as seen from other CPUs, even in an otherwise perfectly synchronized
+system.
+
+4.3) Timespec aliasing
+
+Additionally, this lack of serialization from the TSC poses another challenge
+when using results of the TSC when measured against another time source.  As
+the TSC is much higher precision, many possible values of the TSC may be read
+while another clock is still expressing the same value.
+
+That is, you may read (T,T+10) while external clock C maintains the same value.
+Due to non-serialized reads, you may actually end up with a range which
+fluctuates - from (T-1.. T+10).  Thus, any time calculated from a TSC, but
+calibrated against an external value may have a range of valid values.
+Re-calibrating this computation may actually cause time, as computed after the
+calibration, to go backwards, compared with time computed before the
+calibration.
+
+This problem is particularly pronounced with an internal time source in Linux,
+the kernel time, which is expressed in the theoretically high resolution
+timespec - but which advances in much larger granularity intervals, sometimes
+at the rate of jiffies, and possibly in catchup modes, at a much larger step.
+
+This aliasing requires care in the computation and recalibration of kvmclock
+and any other values derived from TSC computation (such as TSC virtualization
+itself).
+
+4.4) Migration
+
+Migration of a virtual machine raises problems for timekeeping in two ways.
+First, the migration itself may take time, during which interrupts cannot be
+delivered, and after which, the guest time may need to be caught up.  NTP may
+be able to help to some degree here, as the clock correction required is
+typically small enough to fall in the NTP-correctable window.
+
+An additional concern is that timers based off the TSC (or HPET, if the raw bus
+clock is exposed) may now be running at different rates, requiring compensation
+in some way in the hypervisor by virtualizing these timers.  In addition,
+migrating to a faster machine may preclude the use of a passthrough TSC, as a
+faster clock cannot be made visible to a guest without the potential of time
+advancing faster than usual.  A slower clock is less of a problem, as it can
+always be caught up to the original rate.  KVM clock avoids these problems by
+simply storing multipliers and offsets against the TSC for the guest to convert
+back into nanosecond resolution values.
+
+4.5) Scheduling
+
+Since scheduling may be based on precise timing and firing of interrupts, the
+scheduling algorithms of an operating system may be adversely affected by
+virtualization.  In theory, the effect is random and should be universally
+distributed, but in contrived as well as real scenarios (guest device access,
+causes of virtualization exits, possible context switch), this may not always
+be the case.  The effect of this has not been well studied.
+
+In an attempt to work around this, several implementations have provided a
+paravirtualized scheduler clock, which reveals the true amount of CPU time for
+which a virtual machine has been running.
+
+4.6) Watchdogs
+
+Watchdog timers, such as the lock detector in Linux may fire accidentally when
+running under hardware virtualization due to timer interrupts being delayed or
+misinterpretation of the passage of real time.  Usually, these warnings are
+spurious and can be ignored, but in some circumstances it may be necessary to
+disable such detection.
+
+4.7) Delays and precision timing
+
+Precise timing and delays may not be possible in a virtualized system.  This
+can happen if the system is controlling physical hardware, or issues delays to
+compensate for slower I/O to and from devices.  The first issue is not solvable
+in general for a virtualized system; hardware control software can't be
+adequately virtualized without a full real-time operating system, which would
+require an RT aware virtualization platform.
+
+The second issue may cause performance problems, but this is unlikely to be a
+significant issue.  In many cases these delays may be eliminated through
+configuration or paravirtualization.
+
+4.8) Covert channels and leaks
+
+In addition to the above problems, time information will inevitably leak to the
+guest about the host in anything but a perfect implementation of virtualized
+time.  This may allow the guest to infer the presence of a hypervisor (as in a
+red-pill type detection), and it may allow information to leak between guests
+by using CPU utilization itself as a signalling channel.  Preventing such
+problems would require completely isolated virtual time which may not track
+real time any longer.  This may be useful in certain security or QA contexts,
+but in general isn't recommended for real-world deployment scenarios.

+
+Description
+-----------
+
+APDS990x is a combined ambient light and proximity sensor. ALS and proximity
+functionality are highly connected. ALS measurement path must be running
+while the proximity functionality is enabled.
+
+ALS produces raw measurement values for two channels: Clear channel
+(infrared + visible light) and IR only. However, threshold comparisons happen
+using clear channel only. Lux value and the threshold level on the HW
+might vary quite much depending the spectrum of the light source.
+
+Driver makes necessary conversions to both directions so that user handles
+only lux values. Lux value is calculated using information from the both
+channels. HW threshold level is calculated from the given lux value to match
+with current type of the lightning. Sometimes inaccuracy of the estimations
+lead to false interrupt, but that doesn't harm.
+
+ALS contains 4 different gain steps. Driver automatically
+selects suitable gain step. After each measurement, reliability of the results
+is estimated and new measurement is trigged if necessary.
+
+Platform data can provide tuned values to the conversion formulas if
+values are known. Otherwise plain sensor default values are used.
+
+Proximity side is little bit simpler. There is no need for complex conversions.
+It produces directly usable values.
+
+Driver controls chip operational state using pm_runtime framework.
+Voltage regulators are controlled based on chip operational state.

+
+Description
+-----------
+BH1770GLC and SFH7770 are combined ambient light and proximity sensors.
+ALS and proximity parts operates on their own, but they shares common I2C
+interface and interrupt logic. In principle they can run on their own,
+but ALS side results are used to estimate reliability of the proximity sensor.
+
+ALS produces 16 bit lux values. The chip contains interrupt logic to produce
+low and high threshold interrupts.
+
+Proximity part contains IR-led driver up to 3 IR leds. The chip measures
+amount of reflected IR light and produces proximity result. Resolution is
+8 bit. Driver supports only one channel. Driver uses ALS results to estimate
+reliability of the proximity results. Thus ALS is always running while
+proximity detection is needed.
+
+Driver uses threshold interrupts to avoid need for polling the values.
+Proximity low interrupt doesn't exists in the chip. This is simulated
+by using a delayed work. As long as there is proximity threshold above
+interrupts the delayed work is pushed forward. So, when proximity level goes
+below the threshold value, there is no interrupt and the delayed work will
+finally run. This is handled as no proximity indication.
+
+Chip state is controlled via runtime pm framework when enabled in config.
+
+Calibscale factor is used to hide differences between the chips. By default
+value set to neutral state meaning factor of 1.00. To get proper values,
+calibrated source of light is needed as a reference. Calibscale factor is set
+so that measurement produces about the expected lux value.

+Per-route rto_min support
+	CCID-2 supports the RTAX_RTO_MIN per-route setting for the minimum value
+	of the RTO timer. This setting can be modified via the 'rto_min' option
+	of iproute2; for example:
+		> ip route change 10.0.0.0/24   rto_min 250j dev wlan0
+		> ip route add    10.0.0.254/32 rto_min 800j dev wlan0
+		> ip route show dev wlan0
+	CCID-3 also supports the rto_min setting: it is used to define the lower
+	bound for the expiry of the nofeedback timer. This can be useful on LANs
+	with very low RTTs (e.g., loopback, Gbit ethernet).

 Notes
 =====
-
 DCCP does not travel through NAT successfully at present on many boxes. This is
 because the checksum covers the pseudo-header as per TCP and UDP. Linux NAT
 support for DCCP has been added.

+Phonet Pipe-controller Implementation
+-------------------------------------
+
+Phonet Pipe-controller is enabled by selecting the CONFIG_PHONET_PIPECTRLR Kconfig
+option. It is useful when communicating with those Nokia Modems which do not
+implement Pipe controller in them e.g. Nokia Slim Modem used in ST-Ericsson
+U8500 platform.
+
+The implementation is based on the Data Connection Establishment Sequence
+depicted in 'Nokia Wireless Modem API - Wireless_modem_user_guide.pdf'
+document.
+
+It allows a phonet sequenced socket (host-pep) to initiate a Pipe connection
+between itself and a remote pipe-end point (e.g. modem).
+
+The implementation adds socket options at SOL_PNPIPE level:
+
+ PNPIPE_PIPE_HANDLE
+	It accepts an integer argument for setting value of pipe handle.
+
+  PNPIPE_ENABLE accepts one integer value (int). If set to zero, the pipe
+    is disabled. If the value is non-zero, the pipe is enabled. If the pipe
+    is not (yet) connected, ENOTCONN is error is returned.
+
+The implementation also adds socket 'connect'. On calling the 'connect', pipe
+will be created between the source socket and the destination, and the pipe
+state will be set to PIPE_DISABLED.
+
+After a pipe has been created and enabled successfully, the Pipe data can be
+exchanged between the host-pep and remote-pep (modem).

+

+
+ (*) Cost of temporary mappings.
+
+ (*) i386 PAE.
+
+
+====================
+WHAT IS HIGH MEMORY?
+====================
+
+High memory (highmem) is used when the size of physical memory approaches or
+exceeds the maximum size of virtual memory.  At that point it becomes
+impossible for the kernel to keep all of the available physical memory mapped
+at all times.  This means the kernel needs to start using temporary mappings of
+the pieces of physical memory that it wants to access.
+
+The part of (physical) memory not covered by a permanent mapping is what we
+refer to as 'highmem'.  There are various architecture dependent constraints on
+where exactly that border lies.
+
+In the i386 arch, for example, we choose to map the kernel into every process's
+VM space so that we don't have to pay the full TLB invalidation costs for
+kernel entry/exit.  This means the available virtual memory space (4GiB on
+i386) has to be divided between user and kernel space.
+
+The traditional split for architectures using this approach is 3:1, 3GiB for
+userspace and the top 1GiB for kernel space:
+
+		+--------+ 0xffffffff
+		| Kernel |
+		+--------+ 0xc0000000
+		|        |
+		| User   |
+		|        |
+		+--------+ 0x00000000
+
+This means that the kernel can at most map 1GiB of physical memory at any one
+time, but because we need virtual address space for other things - including
+temporary maps to access the rest of the physical memory - the actual direct
+map will typically be less (usually around ~896MiB).
+
+Other architectures that have mm context tagged TLBs can have separate kernel
+and user maps.  Some hardware (like some ARMs), however, have limited virtual
+space when they use mm context tags.
+
+
+==========================
+TEMPORARY VIRTUAL MAPPINGS
+==========================
+
+The kernel contains several ways of creating temporary mappings:
+
+ (*) vmap().  This can be used to make a long duration mapping of multiple
+     physical pages into a contiguous virtual space.  It needs global
+     synchronization to unmap.
+
+ (*) kmap().  This permits a short duration mapping of a single page.  It needs
+     global synchronization, but is amortized somewhat.  It is also prone to
+     deadlocks when using in a nested fashion, and so it is not recommended for
+     new code.
+
+ (*) kmap_atomic().  This permits a very short duration mapping of a single
+     page.  Since the mapping is restricted to the CPU that issued it, it
+     performs well, but the issuing task is therefore required to stay on that
+     CPU until it has finished, lest some other task displace its mappings.
+
+     kmap_atomic() may also be used by interrupt contexts, since it is does not
+     sleep and the caller may not sleep until after kunmap_atomic() is called.
+
+     It may be assumed that k[un]map_atomic() won't fail.
+
+
+=================
+USING KMAP_ATOMIC
+=================
+
+When and where to use kmap_atomic() is straightforward.  It is used when code
+wants to access the contents of a page that might be allocated from high memory
+(see __GFP_HIGHMEM), for example a page in the pagecache.  The API has two
+functions, and they can be used in a manner similar to the following:
+
+	/* Find the page of interest. */
+	struct page *page = find_get_page(mapping, offset);
+
+	/* Gain access to the contents of that page. */
+	void *vaddr = kmap_atomic(page);
+
+	/* Do something to the contents of that page. */
+	memset(vaddr, 0, PAGE_SIZE);
+
+	/* Unmap that page. */
+	kunmap_atomic(vaddr);
+
+Note that the kunmap_atomic() call takes the result of the kmap_atomic() call
+not the argument.
+
+If you need to map two pages because you want to copy from one page to
+another you need to keep the kmap_atomic calls strictly nested, like:
+
+	vaddr1 = kmap_atomic(page1);
+	vaddr2 = kmap_atomic(page2);
+
+	memcpy(vaddr1, vaddr2, PAGE_SIZE);
+
+	kunmap_atomic(vaddr2);
+	kunmap_atomic(vaddr1);
+
+
+==========================
+COST OF TEMPORARY MAPPINGS
+==========================
+
+The cost of creating temporary mappings can be quite high.  The arch has to
+manipulate the kernel's page tables, the data TLB and/or the MMU's registers.
+
+If CONFIG_HIGHMEM is not set, then the kernel will try and create a mapping
+simply with a bit of arithmetic that will convert the page struct address into
+a pointer to the page contents rather than juggling mappings about.  In such a
+case, the unmap operation may be a null operation.
+
+If CONFIG_MMU is not set, then there can be no temporary mappings and no
+highmem.  In such a case, the arithmetic approach will also be used.
+
+
+========
+i386 PAE
+========
+
+The i386 arch, under some circumstances, will permit you to stick up to 64GiB
+of RAM into your 32-bit machine.  This has a number of consequences:
+
+ (*) Linux needs a page-frame structure for each page in the system and the
+     pageframes need to live in the permanent mapping, which means:
+
+ (*) you can have 896M/sizeof(struct page) page-frames at most; with struct
+     page being 32-bytes that would end up being something in the order of 112G
+     worth of pages; the kernel, however, needs to store more than just
+     page-frames in that memory...
+
+ (*) PAE makes your page tables larger - which slows the system down as more
+     data has to be accessed to traverse in TLB fills and the like.  One
+     advantage is that PAE has more PTE bits and can provide advanced features
+     like NX and PAT.
+
+The general recommendation is that you don't use more than 8GiB on a 32-bit
+machine - although more might work for you and your workload, you're pretty
+much on your own - don't expect kernel developers to really care much if things
+come apart.

- * This code manages "OMAP modules" (on-chip devices) and their
- * integration with Linux device driver and bus code.
- *
- * References:
+ * Introduction
+ * ------------
+ * One way to view an OMAP SoC is as a collection of largely unrelated
+ * IP blocks connected by interconnects.  The IP blocks include
+ * devices such as ARM processors, audio serial interfaces, UARTs,
+ * etc.  Some of these devices, like the DSP, are created by TI;
+ * others, like the SGX, largely originate from external vendors.  In
+ * TI's documentation, on-chip devices are referred to as "OMAP
+ * modules."  Some of these IP blocks are identical across several
+ * OMAP versions.  Others are revised frequently.
+ *
+ * These OMAP modules are tied together by various interconnects.
+ * Most of the address and data flow between modules is via OCP-based
+ * interconnects such as the L3 and L4 buses; but there are other
+ * interconnects that distribute the hardware clock tree, handle idle
+ * and reset signaling, supply power, and connect the modules to
+ * various pads or balls on the OMAP package.
+ *
+ * OMAP hwmod provides a consistent way to describe the on-chip
+ * hardware blocks and their integration into the rest of the chip.
+ * This description can be automatically generated from the TI
+ * hardware database.  OMAP hwmod provides a standard, consistent API
+ * to reset, enable, idle, and disable these hardware blocks.  And
+ * hwmod provides a way for other core code, such as the Linux device
+ * code or the OMAP power management and address space mapping code,
+ * to query the hardware database.
+ *
+ * Using hwmod
+ * -----------
+ * Drivers won't call hwmod functions directly.  That is done by the
+ * omap_device code, and in rare occasions, by custom integration code
+ * in arch/arm/ *omap*.  The omap_device code includes functions to
+ * build a struct platform_device using omap_hwmod data, and that is
+ * currently how hwmod data is communicated to drivers and to the
+ * Linux driver model.  Most drivers will call omap_hwmod functions only
+ * indirectly, via pm_runtime*() functions.
+ *
+ * From a layering perspective, here is where the OMAP hwmod code
+ * fits into the kernel software stack:
+ *
+ *            +-------------------------------+
+ *            |      Device driver code       |
+ *            |      (e.g., drivers/)         |
+ *            +-------------------------------+
+ *            |      Linux driver model       |
+ *            |     (platform_device /        |
+ *            |  platform_driver data/code)   |
+ *            +-------------------------------+
+ *            | OMAP core-driver integration  |
+ *            |(arch/arm/mach-omap2/devices.c)|
+ *            +-------------------------------+
+ *            |      omap_device code         |
+ *            | (../plat-omap/omap_device.c)  |
+ *            +-------------------------------+
+ *   ---->    |    omap_hwmod code/data       |    <-----
+ *            | (../mach-omap2/omap_hwmod*)   |
+ *            +-------------------------------+
+ *            | OMAP clock/PRCM/register fns  |
+ *            | (__raw_{read,write}l, clk*)   |
+ *            +-------------------------------+
+ *
+ * Device drivers should not contain any OMAP-specific code or data in
+ * them.  They should only contain code to operate the IP block that
+ * the driver is responsible for.  This is because these IP blocks can
+ * also appear in other SoCs, either from TI (such as DaVinci) or from
+ * other manufacturers; and drivers should be reusable across other
+ * platforms.
+ *
+ * The OMAP hwmod code also will attempt to reset and idle all on-chip
+ * devices upon boot.  The goal here is for the kernel to be
+ * completely self-reliant and independent from bootloaders.  This is
+ * to ensure a repeatable configuration, both to ensure consistent
+ * runtime behavior, and to make it easier for others to reproduce
+ * bugs.
+ *
+ * OMAP module activity states
+ * ---------------------------
+ * The hwmod code considers modules to be in one of several activity
+ * states.  IP blocks start out in an UNKNOWN state, then once they
+ * are registered via the hwmod code, proceed to the REGISTERED state.
+ * Once their clock names are resolved to clock pointers, the module
+ * enters the CLKS_INITED state; and finally, once the module has been
+ * reset and the integration registers programmed, the INITIALIZED state
+ * is entered.  The hwmod code will then place the module into either
+ * the IDLE state to save power, or in the case of a critical system
+ * module, the ENABLED state.
+ *
+ * OMAP core integration code can then call omap_hwmod*() functions
+ * directly to move the module between the IDLE, ENABLED, and DISABLED
+ * states, as needed.  This is done during both the PM idle loop, and
+ * in the OMAP core integration code's implementation of the PM runtime
+ * functions.
+ *

+	  This option determines the caching mode for the kernel.
+
+	  Write-Back caching mode involves the all reads and writes causing
+	  the affected cacheline to be read into the cache first before being
+	  operated upon. Memory is not then updated by a write until the cache
+	  is filled and a cacheline needs to be displaced from the cache to
+	  make room. Only at that point is it written back.
+
+	  Write-Through caching only fetches cachelines from memory on a
+	  read. Writes always get written directly to memory. If the affected
+	  cacheline is also in cache, it will be updated too.
+
+	  The final option is to turn of caching entirely.

+	 * to be updated and be sure the update takes place with the
+	 * new frequency before any guests proceed.
+	 *
+	 * Unfortunately, the combination of hotplug CPU and frequency
+	 * change creates an intractable locking scenario; the order
+	 * of when these callouts happen is undefined with respect to
+	 * CPU hotplug, and they can race with each other.  As such,
+	 * merely setting per_cpu(cpu_tsc_khz) = X during a hotadd is
+	 * undefined; you can actually have a CPU frequency change take
+	 * place in between the computation of X and the setting of the
+	 * variable.  To protect against this problem, all updates of
+	 * the per_cpu tsc_khz variable are done in an interrupt
+	 * protected IPI, and all callers wishing to update the value
+	 * must wait for a synchronous IPI to complete (which is trivial
+	 * if the caller is on the CPU already).  This establishes the
+	 * necessary total order on variable updates.
+	 *
+	 * Note that because a guest time update may take place
+	 * anytime after the setting of the VCPU's request bit, the
+	 * correct TSC value must be set before the request.  However,
+	 * to ensure the update actually makes it to any guest which
+	 * starts running in hardware virtualization between the set
+	 * and the acquisition of the spinlock, we must also ping the

+ *              and function code.
+ *
+ *              The PCI hardware dynamically configures PCI bus numbers
+ *              depending on the bus topology discovered during system
+ *              initialization. This function is invoked during configuration
+ *              of a PCI_Config Operation Region in order to (possibly) update
+ *              the Bus/Device/Function numbers in the pci_id with the actual
+ *              values as determined by the hardware and operating system
+ *              configuration.
+ *
+ *              The pci_id parameter is initially populated during the Operation
+ *              Region initialization. This function is then called, and is
+ *              will make any necessary modifications to the Bus, Device, or
+ *              Function number PCI ID subfields as appropriate for the
+ *              current hardware and OS configuration.
+ *
+ * NOTE:        Created 08/2010. Replaces the previous OSL acpi_os_derive_pci_id
+ *              interface since this feature is OS-independent. This module
+ *              specifically avoids any use of recursion by building a local

+ * PL080 & PL081 both have 16 sets of DMA signals that can be routed to
+ * any channel.
+ *
+ * The PL080 has 8 channels available for simultaneous use, and the PL081
+ * has only two channels. So on these DMA controllers the number of channels
+ * and the number of incoming DMA signals are two totally different things.
+ * It is usually not possible to theoretically handle all physical signals,
+ * so a multiplexing scheme with possible denial of use is necessary.
+ *
+ * The PL080 has a dual bus master, PL081 has a single master.
+ *
+ * Memory to peripheral transfer may be visualized as
+ *	Get data from memory to DMAC
+ *	Until no data left
+ *		On burst request from peripheral
+ *			Destination burst from DMAC to peripheral
+ *			Clear burst request
+ *	Raise terminal count interrupt
+ *
+ * For peripherals with a FIFO:
+ * Source      burst size == half the depth of the peripheral FIFO
+ * Destination burst size == the depth of the peripheral FIFO
+ *
+ * (Bursts are irrelevant for mem to mem transfers - there are no burst
+ * signals, the DMA controller will simply facilitate its AHB master.)
+ *
+ * ASSUMES default (little) endianness for DMA transfers
+ *
+ * Only DMAC flow control is implemented
+ *
+ * Global TODO:
+ * - Break out common code from arch/arm/mach-s3c64xx and share

+ *
+ * This driver only uses "default" mode for all the supported tablets. This

+ *
+ * The "tablet" mode uses some proprietary, yet decipherable protocol, which
+ * represents the correct resolution, but is possibly HID-incompatible (i.e.
+ * indescribable by a report descriptor).
+ *
+ * The purpose of the "ink" mode is unknown.

+ * Original Media Tablet 10.6 inch report descriptor.
+ *
+ * There are at least two versions of this model in the wild. They are
+ * represented by Genius G-Pen M609 (older version) and Genius G-Pen M609X
+ * (newer version).
+ *
+ * Both versions have the usual pen with two barrel buttons and two
+ * identical wheels with center buttons in the top corners of the tablet
+ * base. They also have buttons on the top, between the wheels, for
+ * selecting the wheels' functions and wide/standard mode. In the wide mode
+ * the whole working surface is sensed, in the standard mode a narrower area
+ * is sensed, but the logical report extents remain the same. These modes
+ * correspond roughly to 16:9 and 4:3 aspect ratios respectively.
+ *
+ * The older version has three wheel function buttons ("scroll", "zoom" and
+ * "volume") and two separate buttons for wide and standard mode. The newer
+ * version has four wheel function buttons (plus "brush") and only one
+ * button is used for selecting wide/standard mode. So, the total number of
+ * buttons remains the same, but one of the mode buttons is repurposed as a
+ * wheels' function button in the newer version.
+ *
+ * The wheel functions are:
+ * scroll   - the wheels act as scroll wheels, the center buttons switch
+ *            between vertical and horizontal scrolling;
+ * zoom     - the wheels zoom in/out, the buttons supposedly reset to 100%;
+ * volume   - the wheels control the sound volume, the buttons mute;
+ * brush    - the wheels are supposed to control brush width in a graphics
+ *            editor, the buttons do nothing.
+ *
+ * Below is the newer version's report descriptor. It may very well be that
+ * the older version's descriptor is different and thus it won't be
+ * supported.
+ *
+ * The mouse report (ID 1) only uses the wheel field for reporting the tablet
+ * wheels' scroll mode. The keyboard report (ID 13) is used to report the
+ * wheels' zoom and brush control functions as key presses. The report ID 12
+ * is used to report the wheels' volume control functions. The stylus report
+ * (ID 16) has the same problems as the Slim Tablet 5.8 inch report has.
+ *
+ * The rest of the reports are unused, at least in the default configuration.
+ * The purpose of the features is unknown.

+ * Original Media Tablet 14.1 inch report descriptor.
+ *
+ * There are at least two versions of this model in the wild. They are
+ * represented by Genius G-Pen M712 (older version) and Genius G-Pen M712X
+ * (newer version). The hardware difference between these versions is the same
+ * as between older and newer versions of Media Tablet 10.6 inch. The report
+ * descriptors are identical for both versions.
+ *
+ * The function, behavior and report descriptor of this tablet is similar to
+ * that of Media Tablet 10.6 inch. However, there is one more field (with
+ * Consumer AC Pan usage) in the mouse description. Then the tablet X and Y
+ * logical extents both get scaled to 0..16383 range (a hardware limit?),
+ * which kind of defeats the advertised 4000 LPI resolution, considering the
+ * physical extents of 12x7.25 inches. Plus, reports 5, 10 and 255 are used
+ * sometimes (while moving the pen) with unknown purpose. Also, the key codes
+ * generated for zoom in/out are different.

+ * The PCA9541 is a bus master selector. It supports two I2C masters connected
+ * to a single slave bus.
+ *
+ * Before each bus transaction, a master has to acquire bus ownership. After the
+ * transaction is complete, bus ownership has to be released. This fits well
+ * into the I2C multiplexer framework, which provides select and release
+ * functions for this purpose. For this reason, this driver is modeled as
+ * single-channel I2C bus multiplexer.
+ *
+ * This driver assumes that the two bus masters are controlled by two different
+ * hosts. If a single host controls both masters, platform code has to ensure
+ * that only one of the masters is instantiated at any given time.

-  OVERVIEW
-
-  I designed dv1394 as a "pipe" that you can use to shoot DV onto a
-  FireWire bus. In transmission mode, dv1394 does the following:
-
-   1. accepts contiguous frames of DV data from user-space, via write()
-      or mmap() (see dv1394.h for the complete API)
-   2. wraps IEC 61883 packets around the DV data, inserting
-      empty synchronization packets as necessary
-   3. assigns accurate SYT timestamps to the outgoing packets
-   4. shoots them out using the OHCI card's IT DMA engine
-
-   Thanks to Dan Dennedy, we now have a receive mode that does the following:
-
-   1. accepts raw IEC 61883 packets from the OHCI card
-   2. re-assembles the DV data payloads into contiguous frames,
-      discarding empty packets
-   3. sends the DV data to user-space via read() or mmap()
-*/
-
-/*
-  TODO:
-
-  - tunable frame-drop behavior: either loop last frame, or halt transmission
-
-  - use a scatter/gather buffer for DMA programs (f->descriptor_pool)
-    so that we don't rely on allocating 64KB of contiguous kernel memory
-    via pci_alloc_consistent()
-
-  DONE:
-  - during reception, better handling of dropped frames and continuity errors
-  - during reception, prevent DMA from bypassing the irq tasklets
-  - reduce irq rate during reception (1/250 packets).
-  - add many more internal buffers during reception with scatter/gather dma.
-  - add dbc (continuity) checking on receive, increment status.dropped_frames
-    if not continuous.
-  - restart IT DMA after a bus reset
-  - safely obtain and release ISO Tx channels in cooperation with OHCI driver
-  - map received DIF blocks to their proper location in DV frame (ensure
-    recovery if dropped packet)
-  - handle bus resets gracefully (OHCI card seems to take care of this itself(!))
-  - do not allow resizing the user_buf once allocated; eliminate nuke_buffer_mappings
-  - eliminated #ifdef DV1394_DEBUG_LEVEL by inventing macros debug_printk and irq_printk
-  - added wmb() and mb() to places where PCI read/write ordering needs to be enforced
-  - set video->id correctly
-  - store video_cards in an array indexed by OHCI card ID, rather than a list
-  - implement DMA context allocation to cooperate with other users of the OHCI
-  - fix all XXX showstoppers
-  - disable IR/IT DMA interrupts on shutdown
-  - flush pci writes to the card by issuing a read
-  - character device dispatching
-  - switch over to the new kernel DMA API (pci_map_*()) (* needs testing on platforms with IOMMU!)
-  - keep all video_cards in a list (for open() via chardev), set file->private_data = video
-  - dv1394_poll should indicate POLLIN when receiving buffers are available
-  - add proc fs interface to set cip_n, cip_d, syt_offset, and video signal
-  - expose xmit and recv as separate devices (not exclusive)
-  - expose NTSC and PAL as separate devices (can be overridden)

-
-        The ringbuffer cannot be re-allocated or freed while
-        a user program maintains a mapping of it. (note that a mapping
-	can persist even after the device fd is closed!)
-
-	So, only let the user process allocate the DMA buffer once.
-	To resize or deallocate it, you must close the device file
-	and open it again.
-
-	Previously Dan M. hacked out a scheme that allowed the DMA
-	buffer to change by forcefully unmapping it from the user's
-	address space. It was prone to error because it's very hard to
-	track all the places the buffer could have been mapped (we
-	would have had to walk the vma list of every process in the
-	system to be sure we found all the mappings!). Instead, we
-	force the user to choose one buffer size and stick with
-	it. This small sacrifice is worth the huge reduction in
-	error-prone code in dv1394.

-/* ********************
-   **                **
-   **   DV1394 API   **
-   **                **
-   ********************
-
-   There are two methods of operating the DV1394 DV output device.
-
-   1)
-
-   The simplest is an interface based on write(): simply write
-   full DV frames of data to the device, and they will be transmitted
-   as quickly as possible. The FD may be set for non-blocking I/O,
-   in which case you can use select() or poll() to wait for output
-   buffer space.
-
-   To set the DV output parameters (e.g. whether you want NTSC or PAL
-   video), use the DV1394_INIT ioctl, passing in the parameters you
-   want in a struct dv1394_init.
-
-   Example 1:
-         To play a raw .DV file:   cat foo.DV > /dev/dv1394
-	 (cat will use write() internally)
-
-   Example 2:
-           static struct dv1394_init init = {
-	      0x63,        (broadcast channel)
-              4,           (four-frame ringbuffer)
-	      DV1394_NTSC, (send NTSC video)
-	      0, 0         (default empty packet rate)
-           }
-
-	   ioctl(fd, DV1394_INIT, &init);
-
-	   while (1) {
-	          read( <a raw DV file>, buf, DV1394_NTSC_FRAME_SIZE );
-		  write( <the dv1394 FD>, buf, DV1394_NTSC_FRAME_SIZE );
-           }
-
-   2)
-
-   For more control over buffering, and to avoid unnecessary copies
-   of the DV data, you can use the more sophisticated the mmap() interface.
-   First, call the DV1394_INIT ioctl to specify your parameters,
-   including the number of frames in the ringbuffer. Then, calling mmap()
-   on the dv1394 device will give you direct access to the ringbuffer
-   from which the DV card reads your frame data.
-
-   The ringbuffer is simply one large, contiguous region of memory
-   containing two or more frames of packed DV data. Each frame of DV data
-   is 120000 bytes (NTSC) or 144000 bytes (PAL).
-
-   Fill one or more frames in the ringbuffer, then use the DV1394_SUBMIT_FRAMES
-   ioctl to begin I/O. You can use either the DV1394_WAIT_FRAMES ioctl
-   or select()/poll() to wait until the frames are transmitted. Next, you'll
-   need to call the DV1394_GET_STATUS ioctl to determine which ringbuffer
-   frames are clear (ready to be filled with new DV data). Finally, use
-   DV1394_SUBMIT_FRAMES again to send the new data to the DV output.
-
-
-   Example: here is what a four-frame ringbuffer might look like
-            during DV transmission:
-
-
-         frame 0   frame 1   frame 2   frame 3
-
-	*--------------------------------------*
-        | CLEAR   | DV data | DV data | CLEAR  |
-        *--------------------------------------*
-                   <ACTIVE>
-
-	transmission goes in this direction --->>>
-
-
-   The DV hardware is currently transmitting the data in frame 1.
-   Once frame 1 is finished, it will automatically transmit frame 2.
-   (if frame 2 finishes before frame 3 is submitted, the device
-   will continue to transmit frame 2, and will increase the dropped_frames
-   counter each time it repeats the transmission).
-
-
-   If you called DV1394_GET_STATUS at this instant, you would
-   receive the following values:
-
-                  n_frames          = 4
-		  active_frame      = 1
-		  first_clear_frame = 3
-		  n_clear_frames    = 2
-
-   At this point, you should write new DV data into frame 3 and optionally
-   frame 0. Then call DV1394_SUBMIT_FRAMES to inform the device that
-   it may transmit the new frames.
-
-   ERROR HANDLING
-
-   An error (buffer underflow/overflow or a break in the DV stream due
-   to a 1394 bus reset) can be detected by checking the dropped_frames
-   field of struct dv1394_status (obtained through the
-   DV1394_GET_STATUS ioctl).
-
-   The best way to recover from such an error is to re-initialize
-   dv1394, either by using the DV1394_INIT ioctl call, or closing the
-   file descriptor and opening it again. (note that you must unmap all
-   ringbuffer mappings when closing the file descriptor, or else
-   dv1394 will still be considered 'in use').
-
-   MAIN LOOP
-
-   For maximum efficiency and robustness against bus errors, you are
-   advised to model the main loop of your application after the
-   following pseudo-code example:
-
-   (checks of system call return values omitted for brevity; always
-   check return values in your code!)
-
-   while ( frames left ) {
-
-    struct pollfd *pfd = ...;
-
-    pfd->fd = dv1394_fd;
-    pfd->revents = 0;
-    pfd->events = POLLOUT | POLLIN; (OUT for transmit, IN for receive)
-
-    (add other sources of I/O here)
-
-    poll(pfd, 1, -1); (or select(); add a timeout if you want)
-
-    if (pfd->revents) {
-         struct dv1394_status status;
-
-         ioctl(dv1394_fd, DV1394_GET_STATUS, &status);
-
-	 if (status.dropped_frames > 0) {
-	      reset_dv1394();
-         } else {
-              for (int i = 0; i < status.n_clear_frames; i++) {
-	          copy_DV_frame();
-              }
-         }
-    }
-   }
-
-   where copy_DV_frame() reads or writes on the dv1394 file descriptor
-   (read/write mode) or copies data to/from the mmap ringbuffer and
-   then calls ioctl(DV1394_SUBMIT_FRAMES) to notify dv1394 that new
-   frames are availble (mmap mode).
-
-   reset_dv1394() is called in the event of a buffer
-   underflow/overflow or a halt in the DV stream (e.g. due to a 1394
-   bus reset). To guarantee recovery from the error, this function
-   should close the dv1394 file descriptor (and munmap() all
-   ringbuffer mappings, if you are using them), then re-open the
-   dv1394 device (and re-map the ringbuffer).

-
-/* Q: What are cip_n and cip_d? */
-
-/*
-  A: DV video streams do not utilize 100% of the potential bandwidth offered
-  by IEEE 1394 (FireWire). To achieve the correct rate of data transmission,
-  DV devices must periodically insert empty packets into the 1394 data stream.
-  Typically there is one empty packet per 14-16 data-carrying packets.
-
-  Some DV devices will accept a wide range of empty packet rates, while others
-  require a precise rate. If the dv1394 driver produces empty packets at
-  a rate that your device does not accept, you may see ugly patterns on the
-  DV output, or even no output at all.
-
-  The default empty packet insertion rate seems to work for many people; if
-  your DV output is stable, you can simply ignore this discussion. However,
-  we have exposed the empty packet rate as a parameter to support devices that
-  do not work with the default rate.
-
-  The decision to insert an empty packet is made with a numerator/denominator
-  algorithm. Empty packets are produced at an average rate of CIP_N / CIP_D.
-  You can alter the empty packet rate by passing non-zero values for cip_n
-  and cip_d to the INIT ioctl.

-/*
- * Brief Description:
- *
- * This driver implements the Serial Bus Protocol 2 (SBP-2) over IEEE-1394
- * under Linux. The SBP-2 driver is implemented as an IEEE-1394 high-level
- * driver. It also registers as a SCSI lower-level driver in order to accept
- * SCSI commands for transport using SBP-2.
- *
- * You may access any attached SBP-2 (usually storage devices) as regular
- * SCSI devices. E.g. mount /dev/sda1, fdisk, mkfs, etc..
- *
- * See http://www.t10.org/drafts.htm#sbp2 for the final draft of the SBP-2
- * specification and for where to purchase the official standard.
- *
- * TODO:
- *   - look into possible improvements of the SCSI error handlers
- *   - handle Unit_Characteristics.mgt_ORB_timeout and .ORB_size
- *   - handle Logical_Unit_Number.ordered
- *   - handle src == 1 in status blocks
- *   - reimplement the DMA mapping in absence of physical DMA so that
- *     bus_to_virt is no longer required
- *   - debug the handling of absent physical DMA
- *   - replace CONFIG_IEEE1394_SBP2_PHYS_DMA by automatic detection
- *     (this is easy but depends on the previous two TODO items)
- *   - make the parameter serialize_io configurable per device
- *   - move all requests to fetch agent registers into non-atomic context,
- *     replace all usages of sbp2util_node_write_no_wait by true transactions
- * Grep for inline FIXME comments below.

+	The driver supports multiple boards and automatically configures them:
+	PLD IO base addresses are read from jumpers JP1 and JP2,
+	IRQ numbers are read from jumpers JP4 and JP5,
+	SJA1000 IO base addresses are chosen heuristically (first that works).

+ *
+ * @ah: The &struct ath5k_hw
+ * @intval: beacon interval
+ *
+ * This is a workaround for IBSS mode:
+ *
+ * The need for this function arises from the fact that we have 4 separate
+ * HW timer registers (TIMER0 - TIMER3), which are closely related to the
+ * next beacon target time (NBTT), and that the HW updates these timers
+ * seperately based on the current TSF value. The hardware increments each
+ * timer by the beacon interval, when the local TSF coverted to TU is equal
+ * to the value stored in the timer.
+ *
+ * The reception of a beacon with the same BSSID can update the local HW TSF
+ * at any time - this is something we can't avoid. If the TSF jumps to a
+ * time which is later than the time stored in a timer, this timer will not
+ * be updated until the TSF in TU wraps around at 16 bit (the size of the
+ * timers) and reaches the time which is stored in the timer.
+ *
+ * The problem is that these timers are closely related to TIMER0 (NBTT) and
+ * that they define a time "window". When the TSF jumps between two timers
+ * (e.g. ATIM and NBTT), the one in the past will be left behind (not
+ * updated), while the one in the future will be updated every beacon
+ * interval. This causes the window to get larger, until the TSF wraps
+ * around as described above and the timer which was left behind gets
+ * updated again. But - because the beacon interval is usually not an exact
+ * divisor of the size of the timers (16 bit), an unwanted "window" between
+ * these timers has developed!
+ *
+ * This is especially important with the ATIM window, because during
+ * the ATIM window only ATIM frames and no data frames are allowed to be
+ * sent, which creates transmission pauses after each beacon. This symptom
+ * has been described as "ramping ping" because ping times increase linearly
+ * for some time and then drop down again. A wrong window on the DMA beacon
+ * timer has the same effect, so we check for these two conditions.
+ *
+ * Returns true if O.K.

+/************************** EEPROM BANDS ****************************
+ *
+ * The iwl_eeprom_band definitions below provide the mapping from the
+ * EEPROM contents to the specific channel number supported for each
+ * band.
+ *
+ * For example, iwl_priv->eeprom.band_3_channels[4] from the band_3
+ * definition below maps to physical channel 42 in the 5.2GHz spectrum.
+ * The specific geography and calibration information for that channel
+ * is contained in the eeprom map itself.
+ *
+ * During init, we copy the eeprom information and channel map
+ * information into priv->channel_info_24/52 and priv->channel_map_24/52
+ *
+ * channel_map_24/52 provides the index in the channel_info array for a
+ * given channel.  We have to have two separate maps as there is channel
+ * overlap with the 2.4GHz and 5.2GHz spectrum as seen in band_1 and
+ * band_2
+ *
+ * A value of 0xff stored in the channel_map indicates that the channel
+ * is not supported by the hardware at all.
+ *
+ * A value of 0xfe in the channel_map indicates that the channel is not
+ * valid for Tx with the current hardware.  This means that
+ * while the system can tune and receive on a given channel, it may not
+ * be able to associate or transmit any frames on that
+ * channel.  There is no corresponding channel information for that
+ * entry.

+	 This module will allow you the enter and exit PRTM in the BIOS via
+	 sysfs on platforms that support this feature.  System in PRTM will

+	 feature without proper support may void your hardware warranty.
+
+	 If the proper BIOS support is found the driver will load and create
+	 /sys/devices/system/ibm_rtl/.  The "state" variable will indicate
+	 whether or not the BIOS is in PRTM.

- *
- * i1480u's RX handling is simple. i1480u will send the received
- * network packets broken up in fragments; 1 to N fragments make a
- * packet, we assemble them together and deliver the packet with netif_rx().
- *
- * Beacuse each USB transfer is a *single* fragment (except when the
- * transfer contains a first fragment), each URB called thus
- * back contains one or two fragments. So we queue N URBs, each with its own
- * fragment buffer. When a URB is done, we process it (adding to the
- * current skb from the fragment buffer until complete). Once
- * processed, we requeue the URB. There is always a bunch of URBs
- * ready to take data, so the intergap should be minimal.
- *
- * An URB's transfer buffer is the data field of a socket buffer. This
- * reduces copying as data can be passed directly to network layer. If a
- * complete packet or 1st fragment is received the URB's transfer buffer is
- * taken away from it and used to send data to the network layer. In this
- * case a new transfer buffer is allocated to the URB before being requeued.
- * If a "NEXT" or "LAST" fragment is received, the fragment contents is
- * appended to the RX packet under construction and the transfer buffer
- * is reused. To be able to use this buffer to assemble complete packets
- * we set each buffer's size to that of the MAX ethernet packet that can
- * be received. There is thus room for improvement in memory usage.
- *
- * When the max tx fragment size increases, we should be able to read
- * data into the skbs directly with very simple code.
- *
- * ROADMAP:
- *
- *   ENTRY POINTS:
- *
- *     i1480u_rx_setup(): setup RX context [from i1480u_open()]
- *
- *     i1480u_rx_release(): release RX context [from i1480u_stop()]
- *
- *     i1480u_rx_cb(): called when the RX USB URB receives a
- *                     packet. It removes the header and pushes it up
- *                     the Linux netdev stack with netif_rx().
- *
- *       i1480u_rx_buffer()

- * We need to be able to map ethernet addresses to device addresses
- * and back because there is not explicit relationship between the eth
- * addresses used in the ETH frames and the device addresses (no, it
- * would not have been simpler to force as ETH address the MBOA MAC
- * address...no, not at all :).
- *
- * A device has one MBOA MAC address and one device address. It is possible
- * for a device to have more than one virtual MAC address (although a
- * virtual address can be the same as the MBOA MAC address). The device
- * address is guaranteed to be unique among the devices in the extended
- * beacon group (see ECMA 17.1.1). We thus use the device address as index
- * to this cache. We do allow searching based on virtual address as this
- * is how Ethernet frames will be addressed.
- *
- * We need to support virtual EUI-48. Although, right now the virtual
- * EUI-48 will always be the same as the MAC SAP address. The EDA cache
- * entry thus contains a MAC SAP address as well as the virtual address
- * (used to map the network stack address to a neighbor). When we move
- * to support more than one virtual MAC on a host then this organization
- * will have to change. Perhaps a neighbor has a list of WSSs, each with a
- * tag and virtual EUI-48.

- *         over the entire transmission.
- *         If it is a unicast the WSS connection should already be established

- * @returns: 0 on success no tx : WLP header successfully applied to skb buffer,
- *                                calling function can proceed with tx
- *           1 on success with tx : WLP will take over transmission of this
- *                                  frame
- *           <0 on error
- *
- * The network stack (WLP client) is attempting to transmit a frame. We can
- * only transmit data if a local WSS is at least active (connection will be
- * done here if this is a broadcast frame and neighbor also has the WSS
- * active).
- *
- * The frame can be either broadcast or unicast. Broadcast in a WSS is
- * supported via multicast, but we don't support multicast yet (until
- * devices start to support MAB IEs). If a broadcast frame needs to be
- * transmitted it is treated as a unicast frame to each neighbor. In this
- * case the WLP takes over transmission of the skb and returns 1
- * to the caller to indicate so. Also, in this case, if a neighbor has the
- * same WSS activated but is not connected then the WSS connection will be
- * done at this time. The neighbor's virtual address will be learned at
- * this time.
- *
- * The destination address in a unicast frame is the virtual address of the
- * neighbor. This address only becomes known when a WSS connection is
- * established. We thus rely on a broadcast frame to trigger the setup of
- * WSS connections to all neighbors before we are able to send unicast
- * frames to them. This seems reasonable as IP would usually use ARP first
- * before any unicast frames are sent.
- *
- * If we are already connected to the neighbor (neighbor's virtual address
- * is known) we just prepare the WLP header and the caller will continue to
- * send the frame.
- *
- * A failure in this function usually indicates something that cannot be
- * fixed automatically. So, if this function fails (@return < 0) the calling
- * function should not retry to send the frame as it will very likely keep
- * failing.

 /**
+ * DOC: Frame transmission/registration support
+ *
+ * Frame transmission and registration support exists to allow userspace
+ * management entities such as wpa_supplicant react to management frames
+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ *       these registrations are ignored until the interface type is
+ *       changed again. This means that changing the interface type can
+ *       lead to a situation that couldn't otherwise be produced, but
+ *       any such registrations will be dormant in the sense that they
+ *       will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.
+ *
+ * For more technical details, see the corresponding command descriptions
+ * below.

+/**
+ * DOC: Introduction
+ *
+ * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges
+ * userspace and drivers, and offers some utility functionality associated
+ * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used
+ * by all modern wireless drivers in Linux, so that they offer a consistent
+ * API through nl80211. For backward compatibility, cfg80211 also offers
+ * wireless extensions to userspace, but hides them from drivers completely.
+ *
+ * Additionally, cfg80211 contains code to help enforce regulatory spectrum
+ * use restrictions.
+ */
+
+
+/**
+ * DOC: Device registration
+ *
+ * In order for a driver to use cfg80211, it must register the hardware device
+ * with cfg80211. This happens through a number of hardware capability structs
+ * described below.
+ *
+ * The fundamental structure for each device is the 'wiphy', of which each
+ * instance describes a physical wireless device connected to the system. Each
+ * such wiphy can have zero, one, or many virtual interfaces associated with
+ * it, which need to be identified as such by pointing the network interface's
+ * @ieee80211_ptr pointer to a &struct wireless_dev which further describes
+ * the wireless part of the interface, normally this struct is embedded in the
+ * network interface's private data area. Drivers can optionally allow creating
+ * or destroying virtual interfaces on the fly, but without at least one or the
+ * ability to create some the wireless device isn't useful.
+ *
+ * Each wiphy structure contains device capability information, and also has
+ * a pointer to the various operations the driver offers. The definitions and
+ * structures here describe these capabilities in detail.

+/* This function is used by the 'TPROXY' target and the 'socket'

+ *
+ * Explicit TProxy target rule
+ * ===========================
+ *
+ * This is used when the user wants to intercept a connection matching
+ * an explicit iptables rule. In this case the sockets are assumed
+ * matching in preference order:
+ *
+ *   - match: if there's a fully established connection matching the
+ *     _packet_ tuple, it is returned, assuming the redirection
+ *     already took place and we process a packet belonging to an
+ *     established connection
+ *
+ *   - match: if there's a listening socket matching the redirection
+ *     (e.g. on-port & on-ip of the connection), it is returned,
+ *     regardless if it was bound to 0.0.0.0 or an explicit
+ *     address. The reasoning is that if there's an explicit rule, it
+ *     does not really matter if the listener is bound to an interface
+ *     or to 0. The user already stated that he wants redirection
+ *     (since he added the rule).
+ *
+ * "socket" match based redirection (no specific rule)
+ * ===================================================
+ *
+ * There are connections with dynamic endpoints (e.g. FTP data
+ * connection) that the user is unable to add explicit rules
+ * for. These are taken care of by a generic "socket" rule. It is
+ * assumed that the proxy application is trusted to open such
+ * connections without explicit iptables rule (except of course the
+ * generic 'socket' rule). In this case the following sockets are
+ * matched in preference order:
+ *
+ *   - match: if there's a fully established connection matching the
+ *     _packet_ tuple
+ *
+ *   - match: if there's a non-zero bound listener (possibly with a
+ *     non-local address) We don't accept zero-bound listeners, since
+ *     then local services could intercept traffic going through the
+ *     box.
+ *
+ * Please note that there's an overlap between what a TPROXY target
+ * and a socket match will match. Normally if you have both rules the
+ * "socket" match will be the first one, effectively all packets
+ * belonging to established connections going through that one.

-	  depends on IP_DCCP_CCID3 && EXPERIMENTAL
-	  ---help---
-	    Use higher lower bound for nofeedback timer expiration.
-
-	    The TFRC nofeedback timer normally expires after the maximum of 4
-	    RTTs and twice the current send interval (RFC 3448, 4.3). On LANs
-	    with a small RTT this can mean a high processing load and reduced
-	    performance, since then the nofeedback timer is triggered very
-	    frequently.
-
-	    This option enables to set a higher lower bound for the nofeedback
-	    value. Values in units of milliseconds can be set here.
-
-	    A value of 0 disables this feature by enforcing the value specified
-	    in RFC 3448. The following values have been suggested as bounds for
-	    experimental use:
-		* 16-20ms to match the typical multimedia inter-frame interval
-		* 100ms as a reasonable compromise [default]
-		* 1000ms corresponds to the lower TCP RTO bound (RFC 2988, 2.4)
-
-	    The default of 100ms is a compromise between a large value for
-	    efficient DCCP implementations, and a small value to avoid disrupting
-	    the network in times of congestion.
-
-	    The purpose of the nofeedback timer is to slow DCCP down when there
-	    is serious network congestion: experimenting with larger values should
-	    therefore not be performed on WANs.

-   Semantics of nexthop is very messy by historical reasons.

-   b) gateway must be on-link address, possibly
-      described not by an ifaddr, but also by a direct route.
-   c) If both gateway and interface are specified, they should not
-      contradict.
-   d) If we use tunnel routes, gateway could be not on-link.
-
-   Attempt to reconcile all of these (alas, self-contradictory) conditions
-   results in pretty ugly and hairy code with obscure logic.
-
-   I chose to generalized it instead, so that the size
-   of code does not increase practically, but it becomes
-   much more general.
-   Every prefix is assigned a "scope" value: "host" is local address,
-   "link" is direct route,
-   [ ... "site" ... "interior" ... ]
-   and "universe" is true gateway route with global meaning.
-
-   Every prefix refers to a set of "nexthop"s (gw, oif),

+ * - support for all forwarding methods, not only NAT
+ * - FTP support (NAT), ability to support other NAT apps with expectations
+ * - to correctly create expectations for related NAT connections the proper
+ * NF conntrack support must be already installed, eg. ip_vs_ftp requires
+ * nf_conntrack_ftp ... iptables_nat for the same ports (but no iptables
+ * NAT rules are needed)
+ * - alter reply for NAT when forwarding packet in original direction:
+ * conntrack from client in NEW or RELATED (Passive FTP DATA) state or
+ * when RELATED conntrack is created from real server (Active FTP DATA)
+ * - if iptables_nat is not loaded the Passive FTP will not work (the

 This command displays the symbolic event types which can be selected in the
 various perf commands with the -e option.
 
+EVENT MODIFIERS
+---------------
+
+Events can optionally have a modifer by appending a colon and one or
+more modifiers.  Modifiers allow the user to restrict when events are
+counted with 'u' for user-space, 'k' for kernel, 'h' for hypervisor.
+
+The 'p' modifier can be used for specifying how precise the instruction
+address should be. The 'p' modifier is currently only implemented for
+Intel PEBS and can be specified multiple times:
+  0 - SAMPLE_IP can have arbitrary skid
+  1 - SAMPLE_IP must have constant skid
+  2 - SAMPLE_IP requested to have 0 skid
+  3 - SAMPLE_IP must have 0 skid
+
+The PEBS implementation now supports up to 2.
+
 RAW HARDWARE EVENT DESCRIPTOR
 -----------------------------
