+
+
+1. Introduction
+
+cpufreq-stats is a driver that provices CPU frequency statistics for each CPU.
+This statistics is provided in /sysfs as a bunch of read_only interfaces. This
+interface (when configured) will appear in a seperate directory under cpufreq
+in /sysfs (<sysfs root>/devices/system/cpu/cpuX/cpufreq/stats/) for each CPU.
+Various statistics will form read_only files under this directory.
+
+This driver is designed to be independent of any particular cpufreq_driver
+that may be running on your CPU. So, it will work with any cpufreq_driver.
+
+
+2. Statistics Provided (with example)
+
+cpufreq stats provides following statistics (explained in detail below).
+-  time_in_state
+-  total_trans
+-  trans_table
+
+All the statistics will be from the time the stats driver has been inserted 
+to the time when a read of a particular statistic is done. Obviously, stats 
+driver will not have any information about the the frequcny transitions before
+the stats driver insertion.
+

+--------------------------------------------------------------------------------
+
+-  time_in_state
+This gives the amount of time spent in each of the frequencies supported by
+this CPU. The cat output will have "<frequency> <time>" pair in each line, which
+will mean this CPU spent <time> usertime units of time at <frequency>. Output
+will have one line for each of the supported freuencies. usertime units here 
+is 10mS (similar to other time exported in /proc).

+
+
+-  total_trans
+This gives the total number of frequency transitions on this CPU. The cat 
+output will have a single count which is the total number of frequency
+transitions.
+
+--------------------------------------------------------------------------------
+<mysystem>:/sys/devices/system/cpu/cpu0/cpufreq/stats # cat total_trans

+--------------------------------------------------------------------------------
+
+-  trans_table
+This will give a fine grained information about all the CPU frequency
+transitions. The cat output here is a two dimensional matrix, where an entry
+<i,j> (row i, column j) represents the count of number of transitions from 
+Freq_i to Freq_j. Freq_i is in descending order with increasing rows and 
+Freq_j is in descending order with increasing columns. The output here also 
+contains the actual freq values for each row and column for better readability.

+1. Cpusets
+==========
+
+1.1 What are cpusets ?
+----------------------
+
+Cpusets provide a mechanism for assigning a set of CPUs and Memory
+Nodes to a set of tasks.
+
+Cpusets constrain the CPU and Memory placement of tasks to only
+the resources within a tasks current cpuset.  They form a nested
+hierarchy visible in a virtual file system.  These are the essential
+hooks, beyond what is already present, required to manage dynamic
+job placement on large systems.
+
+Each task has a pointer to a cpuset.  Multiple tasks may reference
+the same cpuset.  Requests by a task, using the sched_setaffinity(2)
+system call to include CPUs in its CPU affinity mask, and using the
+mbind(2) and set_mempolicy(2) system calls to include Memory Nodes
+in its memory policy, are both filtered through that tasks cpuset,
+filtering out any CPUs or Memory Nodes not in that cpuset.  The
+scheduler will not schedule a task on a CPU that is not allowed in
+its cpus_allowed vector, and the kernel page allocator will not
+allocate a page on a node that is not allowed in the requesting tasks
+mems_allowed vector.
+
+If a cpuset is cpu or mem exclusive, no other cpuset, other than a direct
+ancestor or descendent, may share any of the same CPUs or Memory Nodes.
+
+User level code may create and destroy cpusets by name in the cpuset
+virtual file system, manage the attributes and permissions of these
+cpusets and which CPUs and Memory Nodes are assigned to each cpuset,
+specify and query to which cpuset a task is assigned, and list the
+task pids assigned to a cpuset.
+
+
+1.2 Why are cpusets needed ?
+----------------------------
+
+The management of large computer systems, with many processors (CPUs),
+complex memory cache hierarchies and multiple Memory Nodes having
+non-uniform access times (NUMA) presents additional challenges for
+the efficient scheduling and memory placement of processes.
+
+Frequently more modest sized systems can be operated with adequate
+efficiency just by letting the operating system automatically share
+the available CPU and Memory resources amongst the requesting tasks.
+
+But larger systems, which benefit more from careful processor and
+memory placement to reduce memory access times and contention,
+and which typically represent a larger investment for the customer,
+can benefit from explictly placing jobs on properly sized subsets of
+the system.
+
+This can be especially valuable on:
+
+    * Web Servers running multiple instances of the same web application,
+    * Servers running different applications (for instance, a web server
+      and a database), or
+    * NUMA systems running large HPC applications with demanding
+      performance characteristics.
+
+These subsets, or "soft partitions" must be able to be dynamically
+adjusted, as the job mix changes, without impacting other concurrently
+executing jobs.
+
+The kernel cpuset patch provides the minimum essential kernel
+mechanisms required to efficiently implement such subsets.  It
+leverages existing CPU and Memory Placement facilities in the Linux
+kernel to avoid any additional impact on the critical scheduler or
+memory allocator code.
+
+
+1.3 How are cpusets implemented ?
+---------------------------------
+
+Cpusets provide a Linux kernel (2.6.7 and above) mechanism to constrain
+which CPUs and Memory Nodes are used by a process or set of processes.
+
+The Linux kernel already has a pair of mechanisms to specify on which
+CPUs a task may be scheduled (sched_setaffinity) and on which Memory
+Nodes it may obtain memory (mbind, set_mempolicy).
+
+Cpusets extends these two mechanisms as follows:
+
+ - Cpusets are sets of allowed CPUs and Memory Nodes, known to the
+   kernel.
+ - Each task in the system is attached to a cpuset, via a pointer
+   in the task structure to a reference counted cpuset structure.
+ - Calls to sched_setaffinity are filtered to just those CPUs
+   allowed in that tasks cpuset.
+ - Calls to mbind and set_mempolicy are filtered to just
+   those Memory Nodes allowed in that tasks cpuset.
+ - The root cpuset contains all the systems CPUs and Memory
+   Nodes.
+ - For any cpuset, one can define child cpusets containing a subset
+   of the parents CPU and Memory Node resources.
+ - The hierarchy of cpusets can be mounted at /dev/cpuset, for
+   browsing and manipulation from user space.
+ - A cpuset may be marked exclusive, which ensures that no other
+   cpuset (except direct ancestors and descendents) may contain
+   any overlapping CPUs or Memory Nodes.
+ - You can list all the tasks (by pid) attached to any cpuset.
+
+The implementation of cpusets requires a few, simple hooks
+into the rest of the kernel, none in performance critical paths:
+
+ - in main/init.c, to initialize the root cpuset at system boot.
+ - in fork and exit, to attach and detach a task from its cpuset.
+ - in sched_setaffinity, to mask the requested CPUs by what's
+   allowed in that tasks cpuset.
+ - in sched.c migrate_all_tasks(), to keep migrating tasks within
+   the CPUs allowed by their cpuset, if possible.
+ - in the mbind and set_mempolicy system calls, to mask the requested
+   Memory Nodes by what's allowed in that tasks cpuset.
+ - in page_alloc, to restrict memory to allowed nodes.
+ - in vmscan.c, to restrict page recovery to the current cpuset.
+
+In addition a new file system, of type "cpuset" may be mounted,
+typically at /dev/cpuset, to enable browsing and modifying the cpusets
+presently known to the kernel.  No new system calls are added for
+cpusets - all support for querying and modifying cpusets is via
+this cpuset file system.
+
+Each task under /proc has an added file named 'cpuset', displaying
+the cpuset name, as the path relative to the root of the cpuset file
+system.
+
+The /proc/<pid>/status file for each task has two added lines,
+displaying the tasks cpus_allowed (on which CPUs it may be scheduled)
+and mems_allowed (on which Memory Nodes it may obtain memory),
+in the format seen in the following example:
+
+  Cpus_allowed:   ffffffff,ffffffff,ffffffff,ffffffff
+  Mems_allowed:   ffffffff,ffffffff
+
+Each cpuset is represented by a directory in the cpuset file system
+containing the following files describing that cpuset:
+
+ - cpus: list of CPUs in that cpuset
+ - mems: list of Memory Nodes in that cpuset
+ - cpu_exclusive flag: is cpu placement exclusive?
+ - mem_exclusive flag: is memory placement exclusive?
+ - tasks: list of tasks (by pid) attached to that cpuset
+
+New cpusets are created using the mkdir system call or shell
+command.  The properties of a cpuset, such as its flags, allowed
+CPUs and Memory Nodes, and attached tasks, are modified by writing
+to the appropriate file in that cpusets directory, as listed above.
+
+The named hierarchical structure of nested cpusets allows partitioning
+a large system into nested, dynamically changeable, "soft-partitions".
+
+The attachment of each task, automatically inherited at fork by any
+children of that task, to a cpuset allows organizing the work load
+on a system into related sets of tasks such that each set is constrained
+to using the CPUs and Memory Nodes of a particular cpuset.  A task
+may be re-attached to any other cpuset, if allowed by the permissions
+on the necessary cpuset file system directories.
+
+Such management of a system "in the large" integrates smoothly with
+the detailed placement done on individual tasks and memory regions
+using the sched_setaffinity, mbind and set_mempolicy system calls.
+
+The following rules apply to each cpuset:
+
+ - Its CPUs and Memory Nodes must be a subset of its parents.
+ - It can only be marked exclusive if its parent is.
+ - If its cpu or memory is exclusive, they may not overlap any sibling.
+
+These rules, and the natural hierarchy of cpusets, enable efficient
+enforcement of the exclusive guarantee, without having to scan all
+cpusets every time any of them change to ensure nothing overlaps a
+exclusive cpuset.  Also, the use of a Linux virtual file system (vfs)
+to represent the cpuset hierarchy provides for a familiar permission
+and name space for cpusets, with a minimum of additional kernel code.
+
+1.4 How do I use cpusets ?
+--------------------------
+
+In order to minimize the impact of cpusets on critical kernel
+code, such as the scheduler, and due to the fact that the kernel
+does not support one task updating the memory placement of another
+task directly, the impact on a task of changing its cpuset CPU
+or Memory Node placement, or of changing to which cpuset a task
+is attached, is subtle.
+
+If a cpuset has its Memory Nodes modified, then for each task attached
+to that cpuset, the next time that the kernel attempts to allocate
+a page of memory for that task, the kernel will notice the change
+in the tasks cpuset, and update its per-task memory placement to
+remain within the new cpusets memory placement.  If the task was using
+mempolicy MPOL_BIND, and the nodes to which it was bound overlap with
+its new cpuset, then the task will continue to use whatever subset
+of MPOL_BIND nodes are still allowed in the new cpuset.  If the task
+was using MPOL_BIND and now none of its MPOL_BIND nodes are allowed
+in the new cpuset, then the task will be essentially treated as if it
+was MPOL_BIND bound to the new cpuset (even though its numa placement,
+as queried by get_mempolicy(), doesn't change).  If a task is moved
+from one cpuset to another, then the kernel will adjust the tasks
+memory placement, as above, the next time that the kernel attempts
+to allocate a page of memory for that task.
+
+If a cpuset has its CPUs modified, then each task using that
+cpuset does _not_ change its behavior automatically.  In order to
+minimize the impact on the critical scheduling code in the kernel,
+tasks will continue to use their prior CPU placement until they
+are rebound to their cpuset, by rewriting their pid to the 'tasks'
+file of their cpuset.  If a task had been bound to some subset of its
+cpuset using the sched_setaffinity() call, and if any of that subset
+is still allowed in its new cpuset settings, then the task will be
+restricted to the intersection of the CPUs it was allowed on before,
+and its new cpuset CPU placement.  If, on the other hand, there is
+no overlap between a tasks prior placement and its new cpuset CPU
+placement, then the task will be allowed to run on any CPU allowed
+in its new cpuset.  If a task is moved from one cpuset to another,
+its CPU placement is updated in the same way as if the tasks pid is
+rewritten to the 'tasks' file of its current cpuset.
+
+In summary, the memory placement of a task whose cpuset is changed is
+updated by the kernel, on the next allocation of a page for that task,
+but the processor placement is not updated, until that tasks pid is
+rewritten to the 'tasks' file of its cpuset.  This is done to avoid
+impacting the scheduler code in the kernel with a check for changes
+in a tasks processor placement.
+
+There is an exception to the above.  If hotplug funtionality is used
+to remove all the CPUs that are currently assigned to a cpuset,
+then the kernel will automatically update the cpus_allowed of all
+tasks attached to CPUs in that cpuset to allow all CPUs.  When memory
+hotplug functionality for removing Memory Nodes is available, a
+similar exception is expected to apply there as well.  In general,
+the kernel prefers to violate cpuset placement, over starving a task
+that has had all its allowed CPUs or Memory Nodes taken offline.  User
+code should reconfigure cpusets to only refer to online CPUs and Memory
+Nodes when using hotplug to add or remove such resources.
+
+There is a second exception to the above.  GFP_ATOMIC requests are
+kernel internal allocations that must be satisfied, immediately.
+The kernel may drop some request, in rare cases even panic, if a
+GFP_ATOMIC alloc fails.  If the request cannot be satisfied within
+the current tasks cpuset, then we relax the cpuset, and look for
+memory anywhere we can find it.  It's better to violate the cpuset
+than stress the kernel.
+
+To start a new job that is to be contained within a cpuset, the steps are:
+
+ 1) mkdir /dev/cpuset
+ 2) mount -t cpuset none /dev/cpuset
+ 3) Create the new cpuset by doing mkdir's and write's (or echo's) in
+    the /dev/cpuset virtual file system.
+ 4) Start a task that will be the "founding father" of the new job.
+ 5) Attach that task to the new cpuset by writing its pid to the
+    /dev/cpuset tasks file for that cpuset.
+ 6) fork, exec or clone the job tasks from this founding father task.
+
+For example, the following sequence of commands will setup a cpuset
+named "Charlie", containing just CPUs 2 and 3, and Memory Node 1,
+and then start a subshell 'sh' in that cpuset:
+
+  mount -t cpuset none /dev/cpuset
+  cd /dev/cpuset
+  mkdir Charlie
+  cd Charlie
+  /bin/echo 2-3 > cpus
+  /bin/echo 1 > mems
+  /bin/echo $$ > tasks
+  sh
+  # The subshell 'sh' is now running in cpuset Charlie
+  # The next line should display '/Charlie'
+  cat /proc/self/cpuset
+
+In the case that a change of cpuset includes wanting to move already
+allocated memory pages, consider further the work of IWAMOTO
+Toshihiro <iwamoto@valinux.co.jp> for page remapping and memory
+hotremoval, which can be found at:
+
+  http://people.valinux.co.jp/~iwamoto/mh.html
+
+The integration of cpusets with such memory migration is not yet
+available.
+
+In the future, a C library interface to cpusets will likely be
+available.  For now, the only way to query or modify cpusets is
+via the cpuset file system, using the various cd, mkdir, echo, cat,
+rmdir commands from the shell, or their equivalent from C.
+
+The sched_setaffinity calls can also be done at the shell prompt using
+SGI's runon or Robert Love's taskset.  The mbind and set_mempolicy
+calls can be done at the shell prompt using the numactl command
+(part of Andi Kleen's numa package).
+
+2. Usage Examples and Syntax
+============================
+
+2.1 Basic Usage
+---------------
+
+Creating, modifying, using the cpusets can be done through the cpuset
+virtual filesystem.
+
+To mount it, type:
+# mount -t cpuset none /dev/cpuset
+
+Then under /dev/cpuset you can find a tree that corresponds to the
+tree of the cpusets in the system. For instance, /dev/cpuset
+is the cpuset that holds the whole system.
+
+If you want to create a new cpuset under /dev/cpuset:
+# cd /dev/cpuset
+# mkdir my_cpuset
+
+Now you want to do something with this cpuset.
+# cd my_cpuset
+
+In this directory you can find several files:
+# ls
+cpus  cpu_exclusive  mems  mem_exclusive  tasks
+
+Reading them will give you information about the state of this cpuset:
+the CPUs and Memory Nodes it can use, the processes that are using
+it, its properties.  By writing to these files you can manipulate
+the cpuset.
+
+Set some flags:
+# /bin/echo 1 > cpu_exclusive
+
+Add some cpus:
+# /bin/echo 0-7 > cpus
+
+Now attach your shell to this cpuset:
+# /bin/echo $$ > tasks
+
+You can also create cpusets inside your cpuset by using mkdir in this
+directory.
+# mkdir my_sub_cs
+
+To remove a cpuset, just use rmdir:
+# rmdir my_sub_cs
+This will fail if the cpuset is in use (has cpusets inside, or has
+processes attached).
+
+2.2 Adding/removing cpus
+------------------------
+
+This is the syntax to use when writing in the cpus or mems files
+in cpuset directories:
+
+# /bin/echo 1-4 > cpus		-> set cpus list to cpus 1,2,3,4
+# /bin/echo 1,2,3,4 > cpus	-> set cpus list to cpus 1,2,3,4
+
+2.3 Setting flags
+-----------------
+
+The syntax is very simple:
+
+# /bin/echo 1 > cpu_exclusive 	-> set flag 'cpu_exclusive'
+# /bin/echo 0 > cpu_exclusive 	-> unset flag 'cpu_exclusive'
+
+2.4 Attaching processes
+-----------------------
+
+# /bin/echo PID > tasks
+
+Note that it is PID, not PIDs. You can only attach ONE task at a time.
+If you have several tasks to attach, you have to do it one after another:
+
+# /bin/echo PID1 > tasks
+# /bin/echo PID2 > tasks
+	...
+# /bin/echo PIDn > tasks
+
+
+3. Questions
+============
+
+Q: what's up with this '/bin/echo' ?
+A: bash's builtin 'echo' command does not check calls to write() against
+   errors. If you use it in the cpuset file system, you won't be
+   able to tell whether a command succeeded or failed.
+
+Q: When I attach processes, only the first of the line gets really attached !
+A: We can only return one error code per call to write(). So you should also
+   put only ONE pid.

+* For the user
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+NOTE: This document describes the usage of the high level CI API as
+in accordance to the Linux DVB API. This is a not a documentation for the,
+existing low level CI API.
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To utilize the High Level CI capabilities,
+
+(1*) This point is valid only for the Twinhan/clones
+  For the Twinhan/Twinhan clones, the dst_ca module handles the CI
+  hardware handling.This module is loaded automatically if a CI
+  (Common Interface, that holds the CAM (Conditional Access Module)
+  is detected.
+
+(2) one requires a userspace application, ca_zap. This small userland
+  application is in charge of sending the descrambling related information
+  to the CAM.
+
+This application requires the following to function properly as of now.
+
+	(a) Tune to a valid channel, with szap.
+	  eg: $ szap -c channels.conf -r "TMC" -x
+
+	(b) a channels.conf containing a valid PMT PID
+
+	  eg: TMC:11996:h:0:27500:278:512:650:321
+
+	  here 278 is a valid PMT PID. the rest of the values are the
+	  same ones that szap uses.
+
+	(c) after running a szap, you have to run ca_zap, for the
+	  descrambler to function,
+
+	  eg: $ ca_zap patched_channels.conf "TMC"
+
+	  The patched means a patch to apply to scan, such that scan can
+	  generate a channels.conf_with pmt, which has this PMT PID info
+	  (NOTE: szap cannot use this channels.conf with the PMT_PID)
+
+
+	(d) Hopeflly Enjoy your favourite subscribed channel as you do with
+	  a FTA card.
+
+(3) Currently ca_zap, and dst_test, both are meant for demonstration
+  purposes only, they can become full fledged applications if necessary.
+
+
+* Cards that fall in this category
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+At present the cards that fall in this category are the Twinhan and it's
+clones, these cards are available as VVMER, Tomato, Hercules, Orange and
+so on.
+
+* CI modules that are supported
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The CI module support is largely dependant upon the firmware on the cards
+Some cards do support almost all of the available CI modules. There is
+nothing much that can be done in order to make additional CI modules
+working with these cards.
+
+Modules that have been tested by this driver at present are
+
+(1) Irdeto 1 and 2 from SCM
+(2) Viaccess from SCM
+(3) Dragoncam
+
+* The High level CI API
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* For the programmer
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+With the High Level CI approach any new card with almost any random
+architecture can be implemented with this style, the definitions
+insidethe switch statement can be easily adapted for any card, thereby
+eliminating the need for any additional ioctls.
+
+The disadvantage is that the driver/hardware has to manage the rest. For
+the application programmer it would be as simple as sending/receiving an
+array to/from the CI ioctls as defined in the Linux DVB API. No changes
+have been made in the API to accomodate this feature.
+
+
+* Why the need for another CI interface ?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+This is one of the most commonly asked question. Well a nice question.
+Strictly speaking this is not a new interface.
+
+The CI interface is defined in the DVB API in ca.h as
+
+typedef struct ca_slot_info {
+	int num;               /* slot number */
+
+	int type;              /* CA interface this slot supports */
+#define CA_CI            1     /* CI high level interface */
+#define CA_CI_LINK       2     /* CI link layer level interface */
+#define CA_CI_PHYS       4     /* CI physical layer level interface */
+#define CA_DESCR         8     /* built-in descrambler */
+#define CA_SC          128     /* simple smart card interface */
+
+	unsigned int flags;
+#define CA_CI_MODULE_PRESENT 1 /* module (or card) inserted */
+#define CA_CI_MODULE_READY   2
+} ca_slot_info_t;
+
+
+
+This CI interface follows the CI high level interface, which is not
+implemented by most applications. Hence this area is revisited.
+
+This CI interface is quite different in the case that it tries to
+accomodate all other CI based devices, that fall into the other categories
+
+This means that this CI interface handles the EN50221 style tags in the
+Application layer only and no session management is taken care of by the
+application. The driver/hardware will take care of all that.
+
+This interface is purely an EN50221 interface exchanging APDU's. This
+means that no session management, link layer or a transport layer do
+exist in this case in the application to driver communication. It is
+as simple as that. The driver/hardware has to take care of that.
+
+
+With this High Level CI interface, the interface can be defined with the
+regular ioctls.
+
+All these ioctls are also valid for the High level CI interface
+
+#define CA_RESET          _IO('o', 128)
+#define CA_GET_CAP        _IOR('o', 129, ca_caps_t)
+#define CA_GET_SLOT_INFO  _IOR('o', 130, ca_slot_info_t)
+#define CA_GET_DESCR_INFO _IOR('o', 131, ca_descr_info_t)
+#define CA_GET_MSG        _IOR('o', 132, ca_msg_t)
+#define CA_SEND_MSG       _IOW('o', 133, ca_msg_t)
+#define CA_SET_DESCR      _IOW('o', 134, ca_descr_t)
+#define CA_SET_PID        _IOW('o', 135, ca_pid_t)
+
+
+On querying the device, the device yields information thus
+
+CA_GET_SLOT_INFO

+APP: Type=[1]
+APP: flags=[1]

+(25) ES type=[4] ES pid=[301]  ES length =[0 (0x0)]
+ca_message length is 25 (0x19) bytes
+EN50221 CA MSG=[ 9f 80 32 19 03 01 2d d1 f0 08 01 09 06 06 04 05 50 ff f1 02 e0 c9 00 00 04 e1 2d 00 00]
+
+
+Not all ioctl's are implemented in the driver from the API, the other
+features of the hardware that cannot be implemented by the API are achieved
+using the CA_GET_MSG and CA_SEND_MSG ioctls. An EN50221 style wrapper is
+used to exchange the data to maintain compatibility with other hardware.
+
+
+/* a message to/from a CI-CAM */
+typedef struct ca_msg {
+	unsigned int index;
+	unsigned int type;
+	unsigned int length;
+	unsigned char msg[256];
+} ca_msg_t;
+
+
+The flow of data can be described thus,

+
+Description
+-----------
+
+The ICH (properly known as the 82801AA), ICH0 (82801AB), ICH2 (82801BA),
+ICH3 (82801CA/CAM) and later devices are Intel chips that are a part of
+Intel's '810' chipset for Celeron-based PCs, '810E' chipset for
+Pentium-based PCs, '815E' chipset, and others.
+
+The ICH chips contain at least SEVEN separate PCI functions in TWO logical
+PCI devices. An output of lspci will show something similar to the
+following:
+
+  00:1e.0 PCI bridge: Intel Corporation: Unknown device 2418 (rev 01)
+  00:1f.0 ISA bridge: Intel Corporation: Unknown device 2410 (rev 01)
+  00:1f.1 IDE interface: Intel Corporation: Unknown device 2411 (rev 01)
+  00:1f.2 USB Controller: Intel Corporation: Unknown device 2412 (rev 01)
+  00:1f.3 Unknown class [0c05]: Intel Corporation: Unknown device 2413 (rev 01)
+
+The SMBus controller is function 3 in device 1f. Class 0c05 is SMBus Serial
+Controller.
+
+If you do NOT see the 24x3 device at function 3, and you can't figure out
+any way in the BIOS to enable it,
+
+The ICH chips are quite similar to Intel's PIIX4 chip, at least in the
+SMBus controller.
+
+See the file i2c-piix4 for some additional information.

+-----------
+
+i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP.
+
+If your 'lspci -v' listing shows something like the following,
+
+00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2)
+        Subsystem: Asustek Computer, Inc.: Unknown device 0c11
+        Flags: 66Mhz, fast devsel, IRQ 5
+        I/O ports at c000 [size=32]
+        Capabilities: <available only to root>
+
+then this driver should support the SMBuses of your motherboard.
+
+
+Notes
+-----
+
+The SMBus adapter in the nForce2 chipset seems to be very similar to the
+SMBus 2.0 adapter in the AMD-8111 southbridge. However, I could only get
+the driver to work with direct I/O access, which is different to the EC
+interface of the AMD-8111. Tested on Asus A7N8X. The ACPI DSDT table of the
+Asus A7N8X lists two SMBuses, both of which are supported by this driver.

+Kernel driver i2c-parport
+
+Author: Jean Delvare <khali@linux-fr.org> 
+
+This is a unified driver for several i2c-over-parallel-port adapters,
+such as the ones made by Philips, Velleman or ELV. This driver is
+meant as a replacement for the older, individual drivers:
+ * i2c-philips-par
+ * i2c-elv
+ * i2c-velleman
+ * video/i2c-parport (NOT the same as this one, dedicated to home brew
+                      teletext adapters)
+
+It currently supports the following devices:
+ * Philips adapter
+ * home brew teletext adapter
+ * Velleman K8000 adapter
+ * ELV adapter
+ * Analog Devices evaluation boards (ADM1025, ADM1030, ADM1031, ADM1032)
+
+These devices use different pinout configurations, so you have to tell
+the driver what you have, using the type module parameter. There is no
+way to autodetect the devices. Support for different pinout configurations
+can be easily added when needed.
+
+
+Building your own adapter
+-------------------------
+
+If you want to build you own i2c-over-parallel-port adapter, here is
+a sample electronics schema (credits go to Sylvain Munaut):

+ - All resitors are 10k.

+ - Pins 4-9 (D2-D7) could be used as VDD is the driver drives them high.
+   The ADM1032 evaluation board uses D4-D7. Beware that the amount of
+   current you can draw from the parallel port is limited. Also note that
+   all connected lines MUST BE driven at the same state, else you'll short
+   circuit the output buffers! So plugging the I2C adapter after loading
+   the i2c-parport module might be a good safety since data line state
+   prior to init may be unknown. 
+ - This is 5V!
+ - Obviously you cannot read SCL (so it's not really standard-compliant).
+   Pretty easy to add, just copy the SDA part and use another input pin.
+   That would give (ELV compatible pinout):

+If possible, you should use the same pinout configuration as existing
+adapters do, so you won't even have to change the code.
+
+
+Similar (but different) drivers
+-------------------------------
+
+This driver is NOT the same as the i2c-pport driver found in the i2c
+package. The i2c-pport driver makes use of modern parallel port features so
+that you don't need additional electronics. It has other restrictions
+however, and was not ported to Linux 2.6 (yet).
+
+This driver is also NOT the same as the i2c-pcf-epp driver found in the
+lm_sensors package. The i2c-pcf-epp driver doesn't use the parallel port as
+an I2C bus directly. Instead, it uses it to control an external I2C bus
+master. That driver was not ported to Linux 2.6 (yet) either.

+Module Parameters
+-----------------
+
+* force: int
+  Forcibly enable the PIIX4. DANGEROUS!
+* force_addr: int
+  Forcibly enable the PIIX4 at the given address. EXTREMELY DANGEROUS!
+* fix_hstcfg: int
+  Fix config register. Needed on some boards (Force CPCI735).
+
+
+Description
+-----------
+
+The PIIX4 (properly known as the 82371AB) is an Intel chip with a lot of
+functionality. Among other things, it implements the PCI bus. One of its
+minor functions is implementing a System Management Bus. This is a true 
+SMBus - you can not access it on I2C levels. The good news is that it
+natively understands SMBus commands and you do not have to worry about
+timing problems. The bad news is that non-SMBus devices connected to it can
+confuse it mightily. Yes, this is known to happen...
+
+Do 'lspci -v' and see whether it contains an entry like this:
+
+0000:00:02.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 02)
+	     Flags: medium devsel, IRQ 9
+
+Bus and device numbers may differ, but the function number must be
+identical (like many PCI devices, the PIIX4 incorporates a number of
+different 'functions', which can be considered as separate devices). If you
+find such an entry, you have a PIIX4 SMBus controller.
+
+On some computers (most notably, some Dells), the SMBus is disabled by
+default. If you use the insmod parameter 'force=1', the kernel module will
+try to enable it. THIS IS VERY DANGEROUS! If the BIOS did not set up a
+correct address for this module, you could get in big trouble (read:
+crashes, data corruption, etc.). Try this only as a last resort (try BIOS
+updates first, for example), and backup first! An even more dangerous
+option is 'force_addr=<IOPORT>'. This will not only enable the PIIX4 like
+'force' foes, but it will also set a new base I/O port address. The SMBus
+parts of the PIIX4 needs a range of 8 of these addresses to function
+correctly. If these addresses are already reserved by some other device,
+you will get into big trouble! DON'T USE THIS IF YOU ARE NOT VERY SURE
+ABOUT WHAT YOU ARE DOING!
+
+The PIIX4E is just an new version of the PIIX4; it is supported as well.
+The PIIX/PIIX3 does not implement an SMBus or I2C bus, so you can't use
+this driver on those mainboards.
+
+The ServerWorks Southbridges, the Intel 440MX, and the Victory766 are
+identical to the PIIX4 in I2C/SMBus support.
+
+A few OSB4 southbridges are known to be misconfigured by the BIOS. In this
+case, you have you use the fix_hstcfg module parameter. Do not use it
+unless you know you have to, because in some cases it also breaks
+configuration on southbridges that don't need it.

+* Introduction
+
+The name "usbmon" in lowercase refers to a facility in kernel which is
+used to collect traces of I/O on the USB bus. This function is analogous
+to a packet socket used by network monitoring tools such as tcpdump(1)
+or Ethereal. Similarly, it is expected that a tool such as usbdump or
+USBMon (with uppercase letters) is used to examine raw traces produced
+by usbmon.
+
+The usbmon reports requests made by peripheral-specific drivers to Host
+Controller Drivers (HCD). So, if HCD is buggy, the traces reported by
+usbmon may not correspond to bus transactions precisely. This is the same
+situation as with tcpdump.
+
+* How to use usbmon to collect raw text traces
+
+Unlike the packet socket, usbmon has an interface which provides traces
+in a text format. This is used for two purposes. First, it serves as a
+common trace exchange format for tools while most sophisticated formats
+are finalized. Second, humans can read it in case tools are not available.
+
+To collect a raw text trace, execute following steps.
+
+1. Prepare
+
+Mount debugfs (it has to be enabled in your kernel configuration), and
+load the usbmon module (if built as module). The second step is skipped
+if usbmon is built into the kernel.
+
+# mount -t debugfs none_debugs /sys/kernel/debug
+# modprobe usbmon
+
+Verify that bus sockets are present.
+
+[root@lembas zaitcev]# ls /sys/kernel/debug/usbmon
+1s  1t  2s  2t  3s  3t  4s  4t
+[root@lembas zaitcev]#
+
+# ls /sys/kernel
+
+2. Find which bus connects to the desired device
+
+Run "cat /proc/bus/usb/devices", and find the T-line which corresponds to
+the device. Usually you do it by looking for the vendor string. If you have
+many similar devices, unplug one and compare two /proc/bus/usb/devices outputs.
+The T-line will have a bus number. Example:
+
+T:  Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  2 Spd=12  MxCh= 0
+D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
+P:  Vendor=0557 ProdID=2004 Rev= 1.00
+S:  Manufacturer=ATEN
+S:  Product=UC100KM V2.00
+
+Bus=03 means it's bus 3.
+
+3. Start 'cat'
+
+# cat /sys/kernel/debug/usbmon/3t > /tmp/1.mon.out
+
+This process will be reading until killed. Naturally, the output can be
+redirected to a desirable location. This is preferred, because it is going
+to be quite long.
+
+4. Perform the desired operation on the USB bus
+
+This is where you do something that creates the traffic: plug in a flash key,
+copy files, control a webcam, etc.
+
+5. Kill cat
+
+Usually it's done with a keyboard interrupt (Control-C).
+
+At this point the output file (/tmp/1.mon.out in this example) can be saved,
+sent by e-mail, or inspected with a text editor. In the last case make sure
+that the file size is not excessive for your favourite editor.
+
+* Raw text data format
+
+The '0t' type data consists of a stream of events, such as URB submission,
+URB callback, submission error. Every event is a text line, which consists
+of whitespace separated words. The number of position of words may depend
+on the event type, but there is a set of words, common for all types.
+
+Here is the list of words, from left to right:
+- URB Tag. This is used to identify URBs is normally a kernel mode address
+ of the URB structure in hexadecimal.
+- Timestamp in microseconds, a decimal number. The timestamp's resolution
+  depends on available clock, and so it can be much worse than a microsecond
+  (if the implementation uses jiffies, for example).
+- Event Type. This type refers to the format of the event, not URB type.
+  Available types are: S - submission, C - callback, E - submission error.
+- "Pipe". The pipe concept is deprecated. This is a composite word, used to
+  be derived from information in pipes. It consists of three fields, separated
+  by colons: URB type and direction, Device address, Endpoint number.
+  Type and direction are encoded with two bytes in the following manner:
+    Ci Co   Control input and output
+    Zi Zo   Isochronous input and output
+    Ii Io   Interrupt input and output
+    Bi Bo   Bulk input and output
+  Device address and Endpoint number are decimal numbers with leading zeroes
+  or 3 and 2 positions, correspondingly.
+- URB Status. This field makes no sense for submissions, but is present
+  to help scripts with parsing. In error case, it contains the error code.
+- Data Length. This is the actual length in the URB.
+- Data tag. The usbmon may not always capture data, even if length is nonzero.
+  Only if tag is '=', the data words are present.
+- Data words follow, in big endian hexadecimal format. Notice that they are
+  not machine words, but really just a byte stream split into words to make
+  it easier to read. Thus, the last word may contain from one to four bytes.
+  The length of collected data is limited and can be less than the data length
+  report in Data Length word.
+
+Here is an example of code to read the data stream in a well known programming
+language:
+
+class ParsedLine {
+	int data_len;		/* Available length of data */
+	byte data[];
+
+	void parseData(StringTokenizer st) {
+		int availwords = st.countTokens();
+		data = new byte[availwords * 4];
+		data_len = 0;
+		while (st.hasMoreTokens()) {
+			String data_str = st.nextToken();
+			int len = data_str.length() / 2;
+			int i;
+			for (i = 0; i < len; i++) {
+				data[data_len] = Byte.parseByte(
+				    data_str.substring(i*2, i*2 + 2),
+				    16);
+				data_len++;
+			}
+		}
+	}
+}
+
+This format is obviously deficient. For example, the setup packet for control
+transfers is not delivered. This will change in the future.
+
+Examples:
+
+An input control transfer to get a port status:
+
+d74ff9a0 2640288196 S Ci:001:00 -115 4 <
+d74ff9a0 2640288202 C Ci:001:00 0 4 = 01010100
+
+An output bulk transfer to send a SCSI command 0x5E in a 31-byte Bulk wrapper
+to a storage device at address 5:

+ * Cross Partition Communication (XPC) support - standard version.
+ *
+ *	XPC provides a message passing capability that crosses partition
+ *	boundaries. This module is made up of two parts:
+ *
+ *	    partition	This part detects the presence/absence of other
+ *			partitions. It provides a heartbeat and monitors
+ *			the heartbeats of other partitions.
+ *
+ *	    channel	This part manages the channels and sends/receives
+ *			messages across them to/from other partitions.
+ *
+ *	There are a couple of additional functions residing in XP, which
+ *	provide an interface to XPC for its users.
+ *
+ *
+ *	Caveats:
+ *
+ *	  . We currently have no way to determine which nasid an IPI came
+ *	    from. Thus, xpc_IPI_send() does a remote AMO write followed by
+ *	    an IPI. The AMO indicates where data is to be pulled from, so
+ *	    after the IPI arrives, the remote partition checks the AMO word.
+ *	    The IPI can actually arrive before the AMO however, so other code
+ *	    must periodically check for this case. Also, remote AMO operations
+ *	    do not reliably time out. Thus we do a remote PIO read solely to
+ *	    know whether the remote partition is down and whether we should
+ *	    stop sending IPIs to it. This remote PIO read operation is set up
+ *	    in a special nofault region so SAL knows to ignore (and cleanup)
+ *	    any errors due to the remote AMO write, PIO read, and/or PIO
+ *	    write operations.
+ *
+ *	    If/when new hardware solves this IPI problem, we should abandon
+ *	    the current approach.

+ * lm92 - Hardware monitoring driver
+ * Copyright (C) 2005  Jean Delvare <khali@linux-fr.org>
+ *
+ * Based on the lm90 driver, with some ideas taken from the lm_sensors
+ * lm92 driver as well.
+ *
+ * The LM92 is a sensor chip made by National Semiconductor. It reports
+ * its own temperature with a 0.0625 deg resolution and a 0.33 deg
+ * accuracy. Complete datasheet can be obtained from National's website
+ * at:
+ *   http://www.national.com/pf/LM/LM92.html
+ *
+ * This driver also supports the MAX6635 sensor chip made by Maxim.
+ * This chip is compatible with the LM92, but has a lesser accuracy
+ * (1.0 deg). Complete datasheet can be obtained from Maxim's website
+ * at:
+ *   http://www.maxim-ic.com/quick_view2.cfm/qv_pk/3074
+ *
+ * Since the LM92 was the first chipset supported by this driver, most
+ * comments will refer to this chipset, but are actually general and
+ * concern all supported chipsets, unless mentioned otherwise.
+ *
+ * Support could easily be added for the National Semiconductor LM76
+ * and Maxim MAX6633 and MAX6634 chips, which are mostly compatible
+ * with the LM92.

+ *	Driver theory of operation:
+ *
+ *	Some access methods and an ISR is defined by the sub-driver 
+ *	(e.g. hp_sdc_mlc.c).  These methods are expected to provide a 
+ *	few bits of logic in addition to raw access to the HIL MLC, 
+ *	specifically, the ISR, which is entirely registered by the 
+ *	sub-driver and invoked directly, must check for record 
+ *	termination or packet match, at which point a semaphore must
+ *	be cleared and then the hil_mlcs_tasklet must be scheduled.
+ *
+ *	The hil_mlcs_tasklet processes the state machine for all MLCs
+ *	each time it runs, checking each MLC's progress at the current
+ *	node in the state machine, and moving the MLC to subsequent nodes
+ *	in the state machine when appropriate.  It will reschedule
+ *	itself if output is pending.  (This rescheduling should be replaced
+ *	at some point with a sub-driver-specific mechanism.)
+ *
+ *	A timer task prods the tasklet once per second to prevent 
+ *	hangups when attached devices do not return expected data
+ *	and to initiate probes of the loop for new devices.

+ * Helge Deller's original hilkbd.c port for PA-RISC.
+ *
+ *
+ * Driver theory of operation:
+ *
+ * hp_sdc_put does all writing to the SDC.  ISR can run on a different 
+ * CPU than hp_sdc_put, but only one CPU runs hp_sdc_put at a time 
+ * (it cannot really benefit from SMP anyway.)  A tasket fit this perfectly.
+ *
+ * All data coming back from the SDC is sent via interrupt and can be read 
+ * fully in the ISR, so there are no latency/throughput problems there.  
+ * The problem is with output, due to the slow clock speed of the SDC 
+ * compared to the CPU.  This should not be too horrible most of the time, 
+ * but if used with HIL devices that support the multibyte transfer command, 
+ * keeping outbound throughput flowing at the 6500KBps that the HIL is 
+ * capable of is more than can be done at HZ=100.
+ *
+ * Busy polling for IBF clear wastes CPU cycles and bus cycles.  hp_sdc.ibf 
+ * is set to 0 when the IBF flag in the status register has cleared.  ISR 
+ * may do this, and may also access the parts of queued transactions related 
+ * to reading data back from the SDC, but otherwise will not touch the 
+ * hp_sdc state. Whenever a register is written hp_sdc.ibf is set to 1.
+ *
+ * The i8042 write index and the values in the 4-byte input buffer
+ * starting at 0x70 are kept track of in hp_sdc.wi, and .r7[], respectively,
+ * to minimize the amount of IO needed to the SDC.  However these values 
+ * do not need to be locked since they are only ever accessed by hp_sdc_put.
+ *
+ * A timer task schedules the tasklet once per second just to make
+ * sure it doesn't freeze up and to allow for bad reads to time out.

+ *    optional locations from 96 to 192 results in the loss of certain
+ *    functionality during boot."
+ *
+ *    Since locations between 96 and 192 are the various paths, most (if not
+ *    all) PA-RISC machines should have them. Anyway, for safety reasons, the
+ *    following code can deal with only 96 bytes of Stable Storage, and all
+ *    sizes between 96 and 192 bytes (provided they are multiple of struct
+ *    device_path size, eg: 128, 160 and 192) to provide full information.
+ *    The code makes no use of data above 192 bytes. One last word: there's one
+ *    path we can always count on: the primary path.

+
+The main webpage for the Philips driver is at the address above. It contains
+a lot of extra information, a FAQ, and the binary plugin 'PWCX'. This plugin
+contains decompression routines that allow you to use higher image sizes and
+framerates; in addition the webcam uses less bandwidth on the USB bus (handy
+if you want to run more than 1 camera simultaneously). These routines fall
+under a NDA, and may therefor not be distributed as source; however, its use
+is completely optional.
+
+You can build this code either into your kernel, or as a module. I recommend
+the latter, since it makes troubleshooting a lot easier. The built-in
+microphone is supported through the USB Audio class.
+
+When you load the module you can set some default settings for the
+camera; some programs depend on a particular image-size or -format and
+don't know how to set it properly in the driver. The options are:
+
+size
+   Can be one of 'sqcif', 'qsif', 'qcif', 'sif', 'cif' or
+   'vga', for an image size of resp. 128x96, 160x120, 176x144,
+   320x240, 352x288 and 640x480 (of course, only for those cameras that 
+   support these resolutions).
+
+fps
+   Specifies the desired framerate. Is an integer in the range of 4-30.
+
+fbufs
+   This paramter specifies the number of internal buffers to use for storing 
+   frames from the cam. This will help if the process that reads images from 
+   the cam is a bit slow or momentarely busy. However, on slow machines it 
+   only introduces lag, so choose carefully. The default is 3, which is 
+   reasonable. You can set it between 2 and 5.
+
+mbufs
+   This is an integer between 1 and 10. It will tell the module the number of
+   buffers to reserve for mmap(), VIDIOCCGMBUF, VIDIOCMCAPTURE and friends.
+   The default is 2, which is adequate for most applications (double
+   buffering).
+      
+   Should you experience a lot of 'Dumping frame...' messages during
+   grabbing with a tool that uses mmap(), you might want to increase if. 
+   However, it doesn't really buffer images, it just gives you a bit more
+   slack when your program is behind. But you need a multi-threaded or
+   forked program to really take advantage of these buffers.
+
+   The absolute maximum is 10, but don't set it too high!  Every buffer takes
+   up 460 KB of RAM, so unless you have a lot of memory setting this to
+   something more than 4 is an absolute waste.  This memory is only
+   allocated during open(), so nothing is wasted when the camera is not in
+   use.
+
+power_save
+   When power_save is enabled (set to 1), the module will try to shut down
+   the cam on close() and re-activate on open(). This will save power and
+   turn off the LED. Not all cameras support this though (the 645 and 646
+   don't have power saving at all), and some models don't work either (they
+   will shut down, but never wake up). Consider this experimental. By
+   default this option is disabled.
+
+compression (only useful with the plugin)
+   With this option you can control the compression factor that the camera
+   uses to squeeze the image through the USB bus. You can set the 
+   parameter between 0 and 3:
+     0 = prefer uncompressed images; if the requested mode is not available
+         in an uncompressed format, the driver will silently switch to low
+         compression.
+     1 = low compression.
+     2 = medium compression.
+     3 = high compression.
+      
+   High compression takes less bandwidth of course, but it could also
+   introduce some unwanted artefacts. The default is 2, medium compression.
+   See the FAQ on the website for an overview of which modes require
+   compression.
+
+   The compression parameter does not apply to the 645 and 646 cameras
+   and OEM models derived from those (only a few). Most cams honour this
+   parameter.
+
+leds
+   This settings takes 2 integers, that define the on/off time for the LED
+   (in milliseconds). One of the interesting things that you can do with
+   this is let the LED blink while the camera is in use. This:
+
+     leds=500,500
+      
+   will blink the LED once every second. But with:
+
+     leds=0,0
+
+   the LED never goes on, making it suitable for silent surveillance.
+
+   By default the camera's LED is on solid while in use, and turned off
+   when the camera is not used anymore.
+
+   This parameter works only with the ToUCam range of cameras (720, 730, 740,
+   750) and OEMs. For other cameras this command is silently ignored, and 
+   the LED cannot be controlled.
+
+   Finally: this parameters does not take effect UNTIL the first time you
+   open the camera device. Until then, the LED remains on.
+
+dev_hint
+   A long standing problem with USB devices is their dynamic nature: you
+   never know what device a camera gets assigned; it depends on module load
+   order, the hub configuration, the order in which devices are plugged in,
+   and the phase of the moon (i.e. it can be random). With this option you
+   can give the driver a hint as to what video device node (/dev/videoX) it
+   should use with a specific camera. This is also handy if you have two
+   cameras of the same model.
+
+   A camera is specified by its type (the number from the camera model,
+   like PCA645, PCVC750VC, etc) and optionally the serial number (visible
+   in /proc/bus/usb/devices). A hint consists of a string with the following
+   format:
+
+      [type[.serialnumber]:]node
+      
+   The square brackets mean that both the type and the serialnumber are
+   optional, but a serialnumber cannot be specified without a type (which
+   would be rather pointless). The serialnumber is separated from the type
+   by a '.'; the node number by a ':'.
+   
+   This somewhat cryptic syntax is best explained by a few examples:
+
+     dev_hint=3,5              The first detected cam gets assigned
+                               /dev/video3, the second /dev/video5. Any
+                               other cameras will get the first free 
+                               available slot (see below).
+
+     dev_hint=645:1,680:2      The PCA645 camera will get /dev/video1,
+                               and a PCVC680 /dev/video2.
+                               
+     dev_hint=645.0123:3,645.4567:0	The PCA645 camera with serialnumber 
+                                        0123 goes to /dev/video3, the same
+                                        camera model with the 4567 serial
+                                        gets /dev/video0.
+
+     dev_hint=750:1,4,5,6       The PCVC750 camera will get /dev/video1, the 
+                                next 3 Philips cams will use /dev/video4 
+                                through /dev/video6.
+
+   Some points worth knowing:
+   - Serialnumbers are case sensitive and must be written full, including 
+     leading zeroes (it's treated as a string).
+   - If a device node is already occupied, registration will fail and 
+     the webcam is not available.
+   - You can have up to 64 video devices; be sure to make enough device
+     nodes in /dev if you want to spread the numbers (this does not apply
+     to devfs). After /dev/video9 comes /dev/video10 (not /dev/videoA).
+   - If a camera does not match any dev_hint, it will simply get assigned
+     the first available device node, just as it used to be.
+
+trace
+   In order to better detect problems, it is now possible to turn on a
+   'trace' of some of the calls the module makes; it logs all items in your
+   kernel log at debug level.
+
+   The trace variable is a bitmask; each bit represents a certain feature.
+   If you want to trace something, look up the bit value(s) in the table 
+   below, add the values together and supply that to the trace variable.
+
+   Value  Value   Description					   Default
+   (dec)  (hex)
+       1    0x1   Module initialization; this will log messages       On
+                  while loading and unloading the module
+
+       2    0x2   probe() and disconnect() traces                     On
+
+       4    0x4   Trace open() and close() calls                      Off
+
+       8    0x8   read(), mmap() and associated ioctl() calls         Off
+
+      16   0x10   Memory allocation of buffers, etc.                  Off
+
+      32   0x20   Showing underflow, overflow and Dumping frame       On
+                  messages
+
+      64   0x40   Show viewport and image sizes                       Off
+
+     128   0x80   PWCX debugging                                      Off
+
+   For example, to trace the open() & read() fuctions, sum 8 + 4 = 12,
+   so you would supply trace=12 during insmod or modprobe. If
+   you want to turn the initialization and probing tracing off, set trace=0.
+   The default value for trace is 35 (0x23).
+
+
+
+Example:
+     
+     # modprobe pwc size=cif fps=15 power_save=1
+
+The fbufs, mbufs and trace parameters are global and apply to all connected
+cameras. Each camera has its own set of buffers.
+
+size and fps only specify defaults when you open() the device; this is to
+accommodate some tools that don't set the size. You can change these
+settings after open() with the Video4Linux ioctl() calls. The default of
+defaults is QCIF size at 10 fps.
+
+The compression parameter is semiglobal; it sets the initial compression
+preference for all camera's, but this parameter can be set per camera with
+the VIDIOCPWCSCQUAL ioctl() call.
+
+All parameters are optional.

+ * Driver for Epson S1D13xxx series framebuffer chips

+ *  linux/drivers/video/skeletonfb.c
+ *  linux/drivers/video/epson1355fb.c
+ *  linux/drivers/video/epson/s1d13xxxfb.c (2.4 driver by Epson)
+ *
+ * Note, currently only tested on S1D13806 with 16bit CRT.
+ * As such, this driver might still contain some hardcoded bits relating to
+ * S1D13806.
+ * Making it work on other S1D13XXX chips should merely be a matter of adding
+ * a few switch()s, some missing glue here and there maybe, and split header
+ * files.
+ *
+ * TODO: - handle dual screen display (CRT and LCD at the same time).
+ *	 - check_var(), mode change, etc.
+ *	 - PM untested.
+ *	 - Accelerated interfaces.
+ *	 - Probably not SMP safe :)

+ * 	This is a simplified schema, the complexity varies depending
+ * 	on the meta type. Obviously, the length of the data must also
+ * 	be provided for non-numeric types.
+ *
+ * 	Additionaly, type dependant modifiers such as shift operators
+ * 	or mask may be applied to extend the functionaliy. As of now,
+ * 	the variable length type supports shifting the byte string to
+ * 	the right, eating up any number of octets and thus supporting
+ * 	wildcard interface name comparisons such as "ppp%" matching
+ * 	ppp0..9.
+ *
+ * 	NOTE: Certain meta values depend on other subsystems and are
+ * 	      only available if that subsytem is enabled in the kernel.

+ *
+ * ==========================================================================
+ *
+ * An extended match (ematch) is a small classification tool not worth
+ * writing a full classifier for. Ematches can be interconnected to form
+ * a logic expression and get attached to classifiers to extend their
+ * functionatlity.
+ *
+ * The userspace part transforms the logic expressions into an array
+ * consisting of multiple sequences of interconnected ematches separated
+ * by markers. Precedence is implemented by a special ematch kind
+ * referencing a sequence beyond the marker of the current sequence
+ * causing the current position in the sequence to be pushed onto a stack
+ * to allow the current position to be overwritten by the position referenced
+ * in the special ematch. Matching continues in the new sequence until a
+ * marker is reached causing the position to be restored from the stack.
+ *
+ * Example:
+ *          A AND (B1 OR B2) AND C AND D
+ *
+ *              ------->-PUSH-------
+ *    -->--    /         -->--      \   -->--
+ *   /     \  /         /     \      \ /     \
+ * +-------+-------+-------+-------+-------+--------+
+ * | A AND | B AND | C AND | D END | B1 OR | B2 END |
+ * +-------+-------+-------+-------+-------+--------+
+ *                    \                      /
+ *                     --------<-POP---------
+ *
+ * where B is a virtual ematch referencing to sequence starting with B1.
+ * 
+ * ==========================================================================
+ *
+ * How to write an ematch in 60 seconds
+ * ------------------------------------
+ * 
+ *   1) Provide a matcher function:
+ *      static int my_match(struct sk_buff *skb, struct tcf_ematch *m,
+ *                          struct tcf_pkt_info *info)
+ *      {
+ *      	struct mydata *d = (struct mydata *) m->data;
+ *
+ *      	if (...matching goes here...)
+ *      		return 1;
+ *      	else
+ *      		return 0;
+ *      }
+ *
+ *   2) Fill out a struct tcf_ematch_ops:
+ *      static struct tcf_ematch_ops my_ops = {
+ *      	.kind = unique id,
+ *      	.datalen = sizeof(struct mydata),
+ *      	.match = my_match,
+ *      	.owner = THIS_MODULE,
+ *      };
+ *
+ *   3) Register/Unregister your ematch:
+ *      static int __init init_my_ematch(void)
+ *      {
+ *      	return tcf_em_register(&my_ops);
+ *      }
+ *
+ *      static void __exit exit_my_ematch(void)
+ *      {
+ *      	return tcf_em_unregister(&my_ops);
+ *      }
+ *
+ *      module_init(init_my_ematch);
+ *      module_exit(exit_my_ematch);
+ *
+ *   4) By now you should have two more seconds left, barely enough to
+ *      open up a beer to watch the compilation going.

+ *  Copyright (c) by James Courtier-Dutton <James@superbug.demon.co.uk>
+ *  Driver p16v chips
+ *  Version: 0.22
+ *
+ *  FEATURES currently supported:
+ *    Output fixed at S32_LE, 2 channel to hw:0,0
+ *    Rates: 44.1, 48, 96, 192.
+ *
+ *  Changelog:
+ *  0.8
+ *    Use separate card based buffer for periods table.
+ *  0.9
+ *    Use 2 channel output streams instead of 8 channel.
+ *       (8 channel output streams might be good for ASIO type output)
+ *    Corrected speaker output, so Front -> Front etc.
+ *  0.10
+ *    Fixed missed interrupts.
+ *  0.11
+ *    Add Sound card model number and names.
+ *    Add Analog volume controls.
+ *  0.12
+ *    Corrected playback interrupts. Now interrupt per period, instead of half period.
+ *  0.13
+ *    Use single trigger for multichannel.
+ *  0.14
+ *    Mic capture now works at fixed: S32_LE, 96000Hz, Stereo.
+ *  0.15
+ *    Force buffer_size / period_size == INTEGER.
+ *  0.16
+ *    Update p16v.c to work with changed alsa api.
+ *  0.17
+ *    Update p16v.c to work with changed alsa api. Removed boot_devs.
+ *  0.18
+ *    Merging with snd-emu10k1 driver.
+ *  0.19
+ *    One stereo channel at 24bit now works.
+ *  0.20
+ *    Added better register defines.
+ *  0.21
+ *    Integrated with snd-emu10k1 driver.
+ *  0.22
+ *    Removed #if 0 ... #endif
+ *
+ *
+ *  BUGS:
+ *    Some stability problems when unloading the snd-p16v kernel module.
+ *    --
+ *
+ *  TODO:
+ *    SPDIF out.
+ *    Find out how to change capture sample rates. E.g. To record SPDIF at 48000Hz.
+ *    Currently capture fixed at 48000Hz.
+ *
+ *    --
+ *  GENERAL INFO:
+ *    Model: SB0240
+ *    P16V Chip: CA0151-DBS
