-What:           /sys/kernel/debug/kmemtrace/
-Date:           July 2008
-Contact:        Eduard - Gabriel Munteanu <eduard.munteanu@linux360.ro>
-Description:
-In kmemtrace-enabled kernels, the following files are created:
-/sys/kernel/debug/kmemtrace/
-        cpu<n>          (0400)  Per-CPU tracing data, see below. (binary)
-        total_overruns  (0400)  Total number of bytes which were dropped from
-                                cpu<n> files because of full buffer condition,
-                                non-binary. (text)
-        abi_version     (0400)  Kernel's kmemtrace ABI version. (text)
-Each per-CPU file should be read according to the relay interface. That is,
-the reader should set affinity to that specific CPU and, as currently done by
-the userspace application (though there are other methods), use poll() with
-an infinite timeout before every read(). Otherwise, erroneous data may be
-read. The binary data has the following _core_ format:
-        Event ID        (1 byte)        Unsigned integer, one of:
-                0 - represents an allocation (KMEMTRACE_EVENT_ALLOC)
-                1 - represents a freeing of previously allocated memory
-                    (KMEMTRACE_EVENT_FREE)
-        Type ID         (1 byte)        Unsigned integer, one of:
-                0 - this is a kmalloc() / kfree()
-                1 - this is a kmem_cache_alloc() / kmem_cache_free()
-                2 - this is a __get_free_pages() et al.
-        Event size      (2 bytes)       Unsigned integer representing the
-                                        size of this event. Used to extend
-                                        kmemtrace. Discard the bytes you
-                                        don't know about.
-        Sequence number (4 bytes)       Signed integer used to reorder data
-                                        logged on SMP machines. Wraparound
-                                        must be taken into account, although
-                                        it is unlikely.
-        Caller address  (8 bytes)       Return address to the caller.
-        Pointer to mem  (8 bytes)       Pointer to target memory area. Can be
-                                        NULL, but not all such calls might be
-                                        recorded.
-In case of KMEMTRACE_EVENT_ALLOC events, the next fields follow:
-        Requested bytes (8 bytes)       Total number of requested bytes,
-                                        unsigned, must not be zero.
-        Allocated bytes (8 bytes)       Total number of actually allocated
-                                        bytes, unsigned, must not be lower
-                                        than requested bytes.
-        Requested flags (4 bytes)       GFP flags supplied by the caller.
-        Target CPU      (4 bytes)       Signed integer, valid for event id 1.
-                                        If equal to -1, target CPU is the same
-                                        as origin CPU, but the reverse might
-                                        not be true.
-The data is made available in the same endianness the machine has.
-Other event ids and type ids may be defined and added. Other fields may be
-added by increasing event size, but see below for details.
-Every modification to the ABI, including new id definitions, are followed
-by bumping the ABI version by one.
-Adding new data to the packet (features) is done at the end of the mandatory
-data:
-        Feature size    (2 byte)
-        Feature ID      (1 byte)
-        Feature data    (Feature size - 3 bytes)

-                How to mount the root file system in uClinux/Blackfin
-                -----------------------------------------------------
-1       Mounting EXT3 File system.
-        ------------------------
-        Creating an EXT3 File system for uClinux/Blackfin:
-Please follow the steps to form the EXT3 File system and mount the same as root
-file system.
-a       Make an ext3 file system as large as you want the final root file
-        system.
-                mkfs.ext3  /dev/ram0 <your-rootfs-size-in-1k-blocks>
-b       Mount this Empty file system on a free directory as:
-                mount -t ext3 /dev/ram0  ./test
-                        where ./test is the empty directory.
-c       Copy your root fs directory that you have so carefully made over.
-                cp -af  /tmp/my_final_rootfs_files/* ./test
-                (For ex: cp -af uClinux-dist/romfs/* ./test)
-d       If you have done everything right till now you should be able to see
-        the required "root" dir's (that's etc, root, bin, lib, sbin...)
-e       Now unmount the file system
-                umount  ./test
-f       Create the root file system image.
-                dd if=/dev/ram0 bs=1k count=<your-rootfs-size-in-1k-blocks> \
-                > ext3fs.img
-Now you have to tell the kernel that will be mounting this file system as
-rootfs.
-So do a make menuconfig under kernel and select the Ext3 journaling file system
-support under File system --> submenu.
-2.      Mounting EXT2 File system.
-        -------------------------
-By default the ext2 file system image will be created if you invoke make from
-the top uClinux-dist directory.
-3.      Mounting CRAMFS File System
-        ----------------------------
-To create a CRAMFS file system image execute the command
-        mkfs.cramfs ./test cramfs.img
-        where ./test is the target directory.
-4.      Mounting ROMFS File System
-        --------------------------
-To create a ROMFS file system image execute the command
-        genromfs -v -V "ROMdisk" -f romfs.img -d ./test
-        where ./test is the target directory
-5.      Mounting the JFFS2 Filesystem
-        -----------------------------
-To create a compressed JFFS filesystem (JFFS2), please execute the command
-        mkfs.jffs2 -d ./test -o jffs2.img
-        where ./test is the target directory.
-However, please make sure the following is in your kernel config.
-/*
- * RAM/ROM/Flash chip drivers
- */
-#define CONFIG_MTD_CFI 1
-#define CONFIG_MTD_ROM 1
-/*
- * Mapping drivers for chip access
- */
-#define CONFIG_MTD_COMPLEX_MAPPINGS 1
-#define CONFIG_MTD_BF533 1
-#undef CONFIG_MTD_UCLINUX
-Through the u-boot boot loader, use the jffs2.img in the corresponding
-partition made in linux-2.6.x/drivers/mtd/maps/bf533_flash.c.
-NOTE -  Currently the Flash driver is available only for EZKIT. Watch out for a
-        STAMP driver soon.
-6.      Mounting the NFS File system
-        -----------------------------
-        For mounting the NFS please do the following in the kernel config.
-        In Networking Support --> Networking options --> TCP/IP networking -->
-                IP: kernel level autoconfiguration
-        Enable BOOTP Support.
-        In Kernel hacking --> Compiled-in kernel boot parameter add the following
-                root=/dev/nfs rw ip=bootp
-        In File system --> Network File system, Enable
-                NFS file system support --> NFSv3 client support
-                Root File system on NFS
-        in uClibc menuconfig, do the following
-        In Networking Support
-                enable Remote Procedure Call (RPC) support
-                        Full RPC Support
-        On the Host side, ensure that /etc/dhcpd.conf looks something like this
-                ddns-update-style ad-hoc;
-                allow bootp;
-                subnet 10.100.4.0 netmask 255.255.255.0 {
-                default-lease-time 122209600;
-                max-lease-time 31557600;
-                group {
-                        host bf533 {
-                                hardware ethernet 00:CF:52:49:C3:01;
-                                fixed-address 10.100.4.50;
-                                option root-path "/home/nfsmount";
-                        }
-                }
-        ensure that /etc/exports looks something like this
-                /home/nfsmount *(rw,no_root_squash,no_all_squash)
-         run the following commands as root (may differ depending on your
-         distribution) :
-                -  service nfs start
-                -  service portmap start
-                -  service dhcpd start
-                -  /usr/sbin/exportfs

+SPI Chip Select behavior:
+With the Blackfin on-chip SPI peripheral, there is some logic tied to the CPHA
+bit whether the Slave Select Line is controlled by hardware (CPHA=0) or
+controlled by software (CPHA=1). However, the Linux SPI bus driver assumes that
+the Slave Select is always under software control and being asserted during
+the entire SPI transfer. - And not just bits_per_word duration.
+In most cases you can utilize SPI MODE_3 instead of MODE_0 to work-around this
+behavior. If your SPI slave device in question requires SPI MODE_0 or MODE_2
+timing, you can utilize the GPIO controlled SPI Slave Select option instead.
+You can even use the same pin whose peripheral role is a SSEL,
+but use it as a GPIO instead.

+ Getting Coccinelle
+~~~~~~~~~~~~~~~~~~~~
+The semantic patches included in the kernel use the 'virtual rule'
+feature which was introduced in Coccinelle version 0.1.11.
+Coccinelle (>=0.2.0) is available through the package manager
+of many distributions, e.g. :
+ - Debian (>=squeeze)
+ - Fedora (>=13)
+ - Ubuntu (>=10.04 Lucid Lynx)
+ - OpenSUSE
+ - Arch Linux
+ - NetBSD
+ - FreeBSD
+You can get the latest version released from the Coccinelle homepage at
+http://coccinelle.lip6.fr/
+Once you have it, run the following command:
+        ./configure
+        make
+as a regular user, and install it with
+        sudo make install
+ Using Coccinelle on the Linux kernel
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+A Coccinelle-specific target is defined in the top level
+Makefile. This target is named 'coccicheck' and calls the 'coccicheck'
+front-end in the 'scripts' directory.
+Four modes are defined: report, patch, context, and org. The mode to
+use is specified by setting the MODE variable with 'MODE=<mode>'.
+'report' generates a list in the following format:
+  file:line:column-column: message
+'patch' proposes a fix, when possible.
+'context' highlights lines of interest and their context in a
+diff-like style.Lines of interest are indicated with '-'.
+'org' generates a report in the Org mode format of Emacs.
+Note that not all semantic patches implement all modes.
+To make a report for every semantic patch, run the following command:
+        make coccicheck MODE=report
+NB: The 'report' mode is the default one.
+To produce patches, run:
+        make coccicheck MODE=patch
+The coccicheck target applies every semantic patch available in the
+subdirectories of 'scripts/coccinelle' to the entire Linux kernel.
+For each semantic patch, a changelog message is proposed.  It gives a
+description of the problem being checked by the semantic patch, and
+includes a reference to Coccinelle.
+As any static code analyzer, Coccinelle produces false
+positives. Thus, reports must be carefully checked, and patches
+reviewed.
+ Using Coccinelle with a single semantic patch
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The optional make variable COCCI can be used to check a single
+semantic patch. In that case, the variable must be initialized with
+the name of the semantic patch to apply.
+For instance:
+        make coccicheck COCCI=<my_SP.cocci> MODE=patch
+or
+        make coccicheck COCCI=<my_SP.cocci> MODE=report
+ Proposing new semantic patches
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+New semantic patches can be proposed and submitted by kernel
+developers. For sake of clarity, they should be organized in the
+subdirectories of 'scripts/coccinelle/'.
+ Detailed description of the 'report' mode
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+'report' generates a list in the following format:
+  file:line:column-column: message
+Example:
+Running
+        make coccicheck MODE=report COCCI=scripts/coccinelle/err_cast.cocci
+will execute the following part of the SmPL script.

+identified.

+What:   /proc/<pid>/oom_adj
+When:   August 2012
+Why:    /proc/<pid>/oom_adj allows userspace to influence the oom killer's
+        badness heuristic used to determine which task to kill when the kernel
+        is out of memory.
+        The badness heuristic has since been rewritten since the introduction of
+        this tunable such that its meaning is deprecated.  The value was
+        implemented as a bitshift on a score generated by the badness()
+        function that did not have any precise units of measure.  With the
+        rewrite, the score is given as a proportion of available memory to the
+        task allocating pages, so using a bitshift which grows the score
+        exponentially is, thus, impossible to tune with fine granularity.
+        A much more powerful interface, /proc/<pid>/oom_score_adj, was
+        introduced with the oom killer rewrite that allows users to increase or
+        decrease the badness() score linearly.  This interface will replace
+        /proc/<pid>/oom_adj.
+        A warning will be emitted to the kernel log if an application uses this
+        deprecated interface.  After it is printed once, future warnings will be
+        suppressed until the kernel is rebooted.

+Description
+-----------
+The Standard Microsystems Corporation (SMSC) EMC2103 chips
+contain up to 4 temperature sensors and a single fan controller.
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4 or 8) to give
+the readings more range or accuracy. Not all RPM values can accurately be
+represented, so some rounding is done. With a divider of 1, the lowest
+representable value is 480 RPM.
+This driver supports RPM based control, to use this a fan target
+should be written to fan1_target and pwm1_enable should be set to 3.
+The 2103-2 and 2103-4 variants have a third temperature sensor, which can
+be connected to two anti-parallel diodes.  These values can be read
+as temp3 and temp4.  If only one diode is attached to this channel, temp4
+will show as "fault".  The module parameter "apd=0" can be used to suppress
+this 4th channel when anti-parallel diodes are not fitted.

+Description
+-----------
+This driver implements support for JEDEC JC 42.4 compliant temperature sensors.
+The driver auto-detects the chips listed above, but can be manually instantiated
+to support other JC 42.4 compliant chips.
+Example: the following will load the driver for a generic JC 42.4 compliant
+temperature sensor at address 0x18 on I2C bus #1:
+# modprobe jc42
+# echo jc42 0x18 > /sys/bus/i2c/devices/i2c-1/new_device
+A JC 42.4 compliant chip supports a single temperature sensor. Minimum, maximum,
+and critical temperature can be configured. There are alarms for high, low,

+There is also an hysteresis to control the thresholds for resetting alarms.
+Per JC 42.4 specification, the hysteresis threshold can be configured to 0, 1.5,

+The LTC4245 chip can be configured to sample all GPIO pins with two methods:
+1) platform data -- see include/linux/i2c/ltc4245.h
+2) OF device tree -- add the "ltc4245,use-extra-gpios" property to each chip
+The default mode of operation is to sample a single GPIO pin.

+Description
+-----------
+This driver permits reading package level temperature sensor embedded inside
+Intel CPU package. The sensors can be in core, uncore, memory controller, or
+other components in a package. The feature is first implemented in Intel Sandy
+Bridge platform.
+Temperature is measured in degrees Celsius and measurement resolution is
+1 degree C. Valid temperatures are from 0 to TjMax degrees C, because the actual
+value of temperature register is in fact a delta from TjMax.
+Temperature known as TjMax is the maximum junction temperature of package.
+We get this from MSR_IA32_TEMPERATURE_TARGET. If the MSR is not accessible,
+we define TjMax as 100 degrees Celsius. At this temperature, protection
+mechanism will perform actions to forcibly cool down the package. Alarm
+may be raised, if the temperature grows enough (more than TjMax) to trigger
+the Out-Of-Spec bit. Following table summarizes the exported sysfs files:
+temp1_input       - Package temperature (in millidegrees Celsius).
+temp1_max        - All cooling devices should be turned on.
+temp1_crit        - Maximum junction temperature (in millidegrees Celsius).
+temp1_crit_alarm - Set when Out-of-spec bit is set, never clears.
+                    Correct CPU operation is no longer guaranteed.

+Description
+-----------
+[From datasheet] The SMM665 is an Active DC Output power supply Controller
+that monitors, margins and cascade sequences power. The part monitors six
+power supply channels as well as VDD, 12V input, two general-purpose analog
+inputs and an internal temperature sensor using a 10-bit ADC.
+Each monitored channel has its own high and low limits, plus a critical
+limit.
+Support for SMM465, SMM764, and SMM766 has been implemented but is untested.
+Usage Notes
+-----------
+This driver does not probe for devices, since there is no register which
+can be safely used to identify the chip. You will have to instantiate
+the devices explicitly. When instantiating the device, you have to specify
+its configuration register address.
+Example: the following will load the driver for an SMM665 at address 0x57
+on I2C bus #1:
+$ modprobe smm665
+$ echo smm665 0x57 > /sys/bus/i2c/devices/i2c-1/new_device
+Sysfs entries
+-------------
+This driver uses the values in the datasheet to convert ADC register values
+into the values specified in the sysfs-interface document. All attributes are
+read only.
+Min, max, lcrit, and crit values are used by the chip to trigger external signals
+and/or other activity. Triggered signals can include HEALTHY, RST, Power Off,
+or Fault depending on the chip configuration. The driver reports values as lcrit
+or crit if exceeding the limits triggers RST, Power Off, or Fault, and as min or
+max otherwise. For details please see the SMM665 datasheet.
+For SMM465 and SMM764, values for Channel E and F are reported but undefined.

+Note on Erase Size and Preferred Erase Size:
+        "erase_size" is the  minimum size, in bytes, of an erase
+        operation.  For MMC, "erase_size" is the erase group size
+        reported by the card.  Note that "erase_size" does not apply
+        to trim or secure trim operations where the minimum size is
+        always one 512 byte sector.  For SD, "erase_size" is 512
+        if the card is block-addressed, 0 otherwise.
+        SD/MMC cards can erase an arbitrarily large area up to and
+        including the whole card.  When erasing a large area it may
+        be desirable to do it in smaller chunks for three reasons:
+                1. A single erase command will make all other I/O on
+                the card wait.  This is not a problem if the whole card
+                is being erased, but erasing one partition will make
+                I/O for another partition on the same card wait for the
+                duration of the erase - which could be a several
+                minutes.
+                2. To be able to inform the user of erase progress.
+                3. The erase timeout becomes too large to be very
+                useful.  Because the erase timeout contains a margin
+                which is multiplied by the size of the erase area,
+                the value can end up being several minutes for large
+                areas.
+        "erase_size" is not the most efficient unit to erase
+        (especially for SD where it is just one sector),
+        hence "preferred_erase_size" provides a good chunk
+        size for erasing large areas.
+        For MMC, "preferred_erase_size" is the high-capacity
+        erase size if a card specifies one, otherwise it is
+        based on the capacity of the card.
+        For SD, "preferred_erase_size" is the allocation unit
+        size specified by the card.
+        "preferred_erase_size" is in bytes.

+                             DNS Resolver Module
+                             ===================
+Contents:
+ - Overview.
+ - Compilation.
+ - Setting up.
+ - Usage.
+ - Mechanism.
+ - Debugging.
+========
+OVERVIEW
+========
+The DNS resolver module provides a way for kernel services to make DNS queries
+by way of requesting a key of key type dns_resolver.  These queries are
+upcalled to userspace through /sbin/request-key.
+These routines must be supported by userspace tools dns.upcall, cifs.upcall and
+request-key.  It is under development and does not yet provide the full feature
+set.  The features it does support include:
+ (*) Implements the dns_resolver key_type to contact userspace.
+It does not yet support the following AFS features:
+ (*) Dns query support for AFSDB resource record.
+This code is extracted from the CIFS filesystem.
+===========
+COMPILATION
+===========
+The module should be enabled by turning on the kernel configuration options:
+        CONFIG_DNS_RESOLVER     - tristate "DNS Resolver support"
+==========
+SETTING UP
+==========
+To set up this facility, the /etc/request-key.conf file must be altered so that
+/sbin/request-key can appropriately direct the upcalls.  For example, to handle
+basic dname to IPv4/IPv6 address resolution, the following line should be
+added:
+        #OP     TYPE            DESC    CO-INFO PROGRAM ARG1 ARG2 ARG3 ...
+        #====== ============    ======= ======= ==========================
+        create  dns_resolver    *       *       /usr/sbin/cifs.upcall %k
+To direct a query for query type 'foo', a line of the following should be added
+before the more general line given above as the first match is the one taken.
+        create  dns_resolver    foo:*   *       /usr/sbin/dns.foo %k
+=====
+USAGE
+=====
+To make use of this facility, one of the following functions that are
+implemented in the module can be called after doing:
+        #include <linux/dns_resolver.h>
+ (1) int dns_query(const char *type, const char *name, size_t namelen,
+                   const char *options, char **_result, time_t *_expiry);
+     This is the basic access function.  It looks for a cached DNS query and if
+     it doesn't find it, it upcalls to userspace to make a new DNS query, which
+     may then be cached.  The key description is constructed as a string of the
+     form:
+                [<type>:]<name>
+     where <type> optionally specifies the particular upcall program to invoke,
+     and thus the type of query to do, and <name> specifies the string to be
+     looked up.  The default query type is a straight hostname to IP address
+     set lookup.
+     The name parameter is not required to be a NUL-terminated string, and its
+     length should be given by the namelen argument.
+     The options parameter may be NULL or it may be a set of options
+     appropriate to the query type.
+     The return value is a string appropriate to the query type.  For instance,
+     for the default query type it is just a list of comma-separated IPv4 and
+     IPv6 addresses.  The caller must free the result.
+     The length of the result string is returned on success, and a negative
+     error code is returned otherwise.  -EKEYREJECTED will be returned if the
+     DNS lookup failed.
+     If _expiry is non-NULL, the expiry time (TTL) of the result will be
+     returned also.
+=========
+MECHANISM
+=========
+The dnsresolver module registers a key type called "dns_resolver".  Keys of
+this type are used to transport and cache DNS lookup results from userspace.
+When dns_query() is invoked, it calls request_key() to search the local
+keyrings for a cached DNS result.  If that fails to find one, it upcalls to
+userspace to get a new result.
+Upcalls to userspace are made through the request_key() upcall vector, and are
+directed by means of configuration lines in /etc/request-key.conf that tell
+/sbin/request-key what program to run to instantiate the key.
+The upcall handler program is responsible for querying the DNS, processing the
+result into a form suitable for passing to the keyctl_instantiate_key()
+routine.  This then passes the data to dns_resolver_instantiate() which strips
+off and processes any options included in the data, and then attaches the
+remainder of the string to the key as its payload.
+The upcall handler program should set the expiry time on the key to that of the
+lowest TTL of all the records it has extracted a result from.  This means that
+the key will be discarded and recreated when the data it holds has expired.
+dns_query() returns a copy of the value attached to the key, or an error if
+that is indicated instead.
+See <file:Documentation/keys-request-key.txt> for further information about
+request-key function.

-        The Wavelan drivers saga
-        ------------------------

-        The Wavelan is a Radio network adapter designed by
-Lucent. Under this generic name is hidden quite a variety of hardware,
-and many Linux driver to support it.

-        This is the driver for the ISA version of the first generation
-of the Wavelan, now discontinued. The device is 2 Mb/s, composed of a
-Intel 82586 controller and a Lucent Modem, and is NOT 802.11 compliant.
-        The driver has been tested with the following hardware :
-        o Wavelan ISA 915 MHz (full length ISA card) 
-        o Wavelan ISA 915 MHz 2.0 (half length ISA card) 
-        o Wavelan ISA 2.4 GHz (full length ISA card, fixed frequency) 
-        o Wavelan ISA 2.4 GHz 2.0 (half length ISA card, frequency selectable)

-composed of a Intel 82593 controller (totally different from the 82586)
-and a Lucent Modem, and NOT 802.11 compatible.
-        The driver has been tested with the following hardware :
-        o Wavelan Pcmcia 915 MHz 2.0 (Pcmcia card + separate

-        This is the driver for the current generation of Wavelan IEEE,
-which is 802.11 compatible. Depending on version, it is 2 Mb/s or 11
-Mb/s, with or without encryption, all implemented in Lucent specific
-DSP (the Hermes).
-        This is a GPL full source PCMCIA driver (ISA is just a Pcmcia
-card with ISA-Pcmcia bridge).
-"wavelan2_cs" driver (Wavelan IEEE, binary)
--------------------
-        o Config :      Not yet in kernel
-        o Location :    ftp://sourceforge.org/pcmcia/contrib/
-        This driver support exactly the same hardware as the previous
-driver, the main difference is that it is based on a binary library
-and supported by Lucent.
-        I hope it clears the confusion ;-)

-                     ====================================
-                     SLOW WORK ITEM EXECUTION THREAD POOL
-                     ====================================
-By: David Howells <dhowells@redhat.com>
-The slow work item execution thread pool is a pool of threads for performing
-things that take a relatively long time, such as making mkdir calls.
-Typically, when processing something, these items will spend a lot of time
-blocking a thread on I/O, thus making that thread unavailable for doing other
-work.
-The standard workqueue model is unsuitable for this class of work item as that
-limits the owner to a single thread or a single thread per CPU.  For some
-tasks, however, more threads - or fewer - are required.
-There is just one pool per system.  It contains no threads unless something
-wants to use it - and that something must register its interest first.  When
-the pool is active, the number of threads it contains is dynamic, varying
-between a maximum and minimum setting, depending on the load.
-====================
-CLASSES OF WORK ITEM
-====================
-This pool support two classes of work items:
- (*) Slow work items.
- (*) Very slow work items.
-The former are expected to finish much quicker than the latter.
-An operation of the very slow class may do a batch combination of several
-lookups, mkdirs, and a create for instance.
-An operation of the ordinarily slow class may, for example, write stuff or
-expand files, provided the time taken to do so isn't too long.
-Operations of both types may sleep during execution, thus tying up the thread
-loaned to it.
-A further class of work item is available, based on the slow work item class:
- (*) Delayed slow work items.
-These are slow work items that have a timer to defer queueing of the item for
-a while.
-THREAD-TO-CLASS ALLOCATION
--------------------------
-Not all the threads in the pool are available to work on very slow work items.
-The number will be between one and one fewer than the number of active threads.
-This is configurable (see the "Pool Configuration" section).
-All the threads are available to work on ordinarily slow work items, but a
-percentage of the threads will prefer to work on very slow work items.
-The configuration ensures that at least one thread will be available to work on
-very slow work items, and at least one thread will be available that won't work
-on very slow work items at all.
-=====================
-USING SLOW WORK ITEMS
-=====================
-Firstly, a module or subsystem wanting to make use of slow work items must
-register its interest:
-         int ret = slow_work_register_user(struct module *module);
-This will return 0 if successful, or a -ve error upon failure.  The module
-pointer should be the module interested in using this facility (almost
-certainly THIS_MODULE).
-Slow work items may then be set up by:
- (1) Declaring a slow_work struct type variable:
-        #include <linux/slow-work.h>
-        struct slow_work myitem;
- (2) Declaring the operations to be used for this item:
-        struct slow_work_ops myitem_ops = {
-                .get_ref = myitem_get_ref,
-                .put_ref = myitem_put_ref,
-                .execute = myitem_execute,
-        };
-     [*] For a description of the ops, see section "Item Operations".
- (3) Initialising the item:
-        slow_work_init(&myitem, &myitem_ops);
-     or:
-        delayed_slow_work_init(&myitem, &myitem_ops);
-     or:
-        vslow_work_init(&myitem, &myitem_ops);
-     depending on its class.
-A suitably set up work item can then be enqueued for processing:
-        int ret = slow_work_enqueue(&myitem);
-This will return a -ve error if the thread pool is unable to gain a reference
-on the item, 0 otherwise, or (for delayed work):
-        int ret = delayed_slow_work_enqueue(&myitem, my_jiffy_delay);
-The items are reference counted, so there ought to be no need for a flush
-operation.  But as the reference counting is optional, means to cancel
-existing work items are also included:
-        cancel_slow_work(&myitem);
-        cancel_delayed_slow_work(&myitem);
-can be used to cancel pending work.  The above cancel function waits for
-existing work to have been executed (or prevent execution of them, depending
-on timing).
-When all a module's slow work items have been processed, and the
-module has no further interest in the facility, it should unregister its
-interest:
-        slow_work_unregister_user(struct module *module);
-The module pointer is used to wait for all outstanding work items for that
-module before completing the unregistration.  This prevents the put_ref() code
-from being taken away before it completes.  module should almost certainly be
-THIS_MODULE.
-================
-HELPER FUNCTIONS
-================
-The slow-work facility provides a function by which it can be determined
-whether or not an item is queued for later execution:
-        bool queued = slow_work_is_queued(struct slow_work *work);
-If it returns false, then the item is not on the queue (it may be executing
-with a requeue pending).  This can be used to work out whether an item on which
-another depends is on the queue, thus allowing a dependent item to be queued
-after it.
-If the above shows an item on which another depends not to be queued, then the
-owner of the dependent item might need to wait.  However, to avoid locking up
-the threads unnecessarily be sleeping in them, it can make sense under some
-circumstances to return the work item to the queue, thus deferring it until
-some other items have had a chance to make use of the yielded thread.
-To yield a thread and defer an item, the work function should simply enqueue
-the work item again and return.  However, this doesn't work if there's nothing
-actually on the queue, as the thread just vacated will jump straight back into
-the item's work function, thus busy waiting on a CPU.
-Instead, the item should use the thread to wait for the dependency to go away,
-but rather than using schedule() or schedule_timeout() to sleep, it should use
-the following function:
-        bool requeue = slow_work_sleep_till_thread_needed(
-                        struct slow_work *work,
-                        signed long *_timeout);
-This will add a second wait and then sleep, such that it will be woken up if
-either something appears on the queue that could usefully make use of the
-thread - and behind which this item can be queued, or if the event the caller
-set up to wait for happens.  True will be returned if something else appeared
-on the queue and this work function should perhaps return, of false if
-something else woke it up.  The timeout is as for schedule_timeout().
-For example:
-        wq = bit_waitqueue(&my_flags, MY_BIT);
-        init_wait(&wait);
-        requeue = false;
-        do {
-                prepare_to_wait(wq, &wait, TASK_UNINTERRUPTIBLE);
-                if (!test_bit(MY_BIT, &my_flags))
-                        break;
-                requeue = slow_work_sleep_till_thread_needed(&my_work,
-                                                             &timeout);
-        } while (timeout > 0 && !requeue);
-        finish_wait(wq, &wait);
-        if (!test_bit(MY_BIT, &my_flags)
-                goto do_my_thing;
-        if (requeue)
-                return; // to slow_work
-===============
-ITEM OPERATIONS
-===============
-Each work item requires a table of operations of type struct slow_work_ops.
-Only ->execute() is required; the getting and putting of a reference and the
-describing of an item are all optional.
- (*) Get a reference on an item:
-        int (*get_ref)(struct slow_work *work);
-     This allows the thread pool to attempt to pin an item by getting a
-     reference on it.  This function should return 0 if the reference was
-     granted, or a -ve error otherwise.  If an error is returned,
-     slow_work_enqueue() will fail.
-     The reference is held whilst the item is queued and whilst it is being
-     executed.  The item may then be requeued with the same reference held, or
-     the reference will be released.
- (*) Release a reference on an item:
-        void (*put_ref)(struct slow_work *work);
-     This allows the thread pool to unpin an item by releasing the reference on
-     it.  The thread pool will not touch the item again once this has been
-     called.
- (*) Execute an item:
-        void (*execute)(struct slow_work *work);
-     This should perform the work required of the item.  It may sleep, it may
-     perform disk I/O and it may wait for locks.
- (*) View an item through /proc:
-        void (*desc)(struct slow_work *work, struct seq_file *m);
-     If supplied, this should print to 'm' a small string describing the work
-     the item is to do.  This should be no more than about 40 characters, and
-     shouldn't include a newline character.
-     See the 'Viewing executing and queued items' section below.
-==================
-POOL CONFIGURATION
-==================
-The slow-work thread pool has a number of configurables:
- (*) /proc/sys/kernel/slow-work/min-threads
-     The minimum number of threads that should be in the pool whilst it is in
-     use.  This may be anywhere between 2 and max-threads.
- (*) /proc/sys/kernel/slow-work/max-threads
-     The maximum number of threads that should in the pool.  This may be
-     anywhere between min-threads and 255 or NR_CPUS * 2, whichever is greater.
- (*) /proc/sys/kernel/slow-work/vslow-percentage
-     The percentage of active threads in the pool that may be used to execute
-     very slow work items.  This may be between 1 and 99.  The resultant number
-     is bounded to between 1 and one fewer than the number of active threads.
-     This ensures there is always at least one thread that can process very
-     slow work items, and always at least one thread that won't.
-==================================
-VIEWING EXECUTING AND QUEUED ITEMS
-==================================
-If CONFIG_SLOW_WORK_DEBUG is enabled, a debugfs file is made available:
-        /sys/kernel/debug/slow_work/runqueue
-through which the list of work items being executed and the queues of items to
-be executed may be viewed.  The owner of a work item is given the chance to
-add some information of its own.
-The contents look something like the following:
-    THR PID   ITEM ADDR        FL MARK  DESC

+delays - Information on the various kernel delay / sleep mechanisms
+-------------------------------------------------------------------
+This document seeks to answer the common question: "What is the
+RightWay (TM) to insert a delay?"
+This question is most often faced by driver writers who have to
+deal with hardware delays and who may not be the most intimately
+familiar with the inner workings of the Linux Kernel.
+Inserting Delays
+----------------
+The first, and most important, question you need to ask is "Is my
+code in an atomic context?"  This should be followed closely by "Does
+it really need to delay in atomic context?" If so...
+ATOMIC CONTEXT:
+        You must use the *delay family of functions. These
+        functions use the jiffie estimation of clock speed
+        and will busy wait for enough loop cycles to achieve
+        the desired delay:
+        ndelay(unsigned long nsecs)
+        udelay(unsigned long usecs)
+        mdelay(unsgined long msecs)
+        udelay is the generally preferred API; ndelay-level
+        precision may not actually exist on many non-PC devices.
+        mdelay is macro wrapper around udelay, to account for
+        possible overflow when passing large arguments to udelay.
+        In general, use of mdelay is discouraged and code should
+        be refactored to allow for the use of msleep.
+NON-ATOMIC CONTEXT:
+        You should use the *sleep[_range] family of functions.
+        There are a few more options here, while any of them may
+        work correctly, using the "right" sleep function will
+        help the scheduler, power management, and just make your
+        driver better :)
+        -- Backed by busy-wait loop:
+                udelay(unsigned long usecs)
+        -- Backed by hrtimers:
+                usleep_range(unsigned long min, unsigned long max)
+        -- Backed by jiffies / legacy_timers
+                msleep(unsigned long msecs)
+                msleep_interruptible(unsigned long msecs)
+        Unlike the *delay family, the underlying mechanism
+        driving each of these calls varies, thus there are
+        quirks you should be aware of.
+        SLEEPING FOR "A FEW" USECS ( < ~10us? ):
+                * Use udelay
+                - Why not usleep?
+                        On slower systems, (embedded, OR perhaps a speed-
+                        stepped PC!) the overhead of setting up the hrtimers
+                        for usleep *may* not be worth it. Such an evaluation
+                        will obviously depend on your specific situation, but
+                        it is something to be aware of.
+        SLEEPING FOR ~USECS OR SMALL MSECS ( 10us - 20ms):
+                * Use usleep_range
+                - Why not msleep for (1ms - 20ms)?
+                        Explained originally here:
+                                http://lkml.org/lkml/2007/8/3/250
+                        msleep(1~20) may not do what the caller intends, and
+                        will often sleep longer (~20 ms actual sleep for any
+                        value given in the 1~20ms range). In many cases this
+                        is not the desired behavior.
+                - Why is there no "usleep" / What is a good range?
+                        Since usleep_range is built on top of hrtimers, the
+                        wakeup will be very precise (ish), thus a simple
+                        usleep function would likely introduce a large number
+                        of undesired interrupts.
+                        With the introduction of a range, the scheduler is
+                        free to coalesce your wakeup with any other wakeup
+                        that may have happened for other reasons, or at the
+                        worst case, fire an interrupt for your upper bound.
+                        The larger a range you supply, the greater a chance
+                        that you will not trigger an interrupt; this should
+                        be balanced with what is an acceptable upper bound on
+                        delay / performance for your specific code path. Exact
+                        tolerances here are very situation specific, thus it
+                        is left to the caller to determine a reasonable range.
+        SLEEPING FOR LARGER MSECS ( 10ms+ )
+                * Use msleep or possibly msleep_interruptible
+                - What's the difference?
+                        msleep sets the current task to TASK_UNINTERRUPTIBLE
+                        whereas msleep_interruptible sets the current task to
+                        TASK_INTERRUPTIBLE before scheduling the sleep. In
+                        short, the difference is whether the sleep can be ended
+                        early by a signal. In general, just use msleep unless
+                        you know you have a need for the interruptible variant.

+details for how to locate the addresses of mcount call sites via objdump.
+This option doesn't make much sense without also implementing dynamic ftrace.
+HAVE_DYNAMIC_FTRACE
+-------------------
+You will first need HAVE_FTRACE_MCOUNT_RECORD and HAVE_FUNCTION_TRACER, so
+scroll your reader back up if you got over eager.
+Once those are out of the way, you will need to implement:
+        - asm/ftrace.h:
+                - MCOUNT_ADDR
+                - ftrace_call_adjust()
+                - struct dyn_arch_ftrace{}
+        - asm code:
+                - mcount() (new stub)
+                - ftrace_caller()
+                - ftrace_call()
+                - ftrace_stub()
+        - C code:
+                - ftrace_dyn_arch_init()
+                - ftrace_make_nop()
+                - ftrace_make_call()
+                - ftrace_update_ftrace_func()
+First you will need to fill out some arch details in your asm/ftrace.h.
+Define MCOUNT_ADDR as the address of your mcount symbol similar to:
+        #define MCOUNT_ADDR ((unsigned long)mcount)
+Since no one else will have a decl for that function, you will need to:
+        extern void mcount(void);
+You will also need the helper function ftrace_call_adjust().  Most people
+will be able to stub it out like so:
+        static inline unsigned long ftrace_call_adjust(unsigned long addr)
+        {
+                return addr;
+        }
 <details to be filled>
+Lastly you will need the custom dyn_arch_ftrace structure.  If you need
+some extra state when runtime patching arbitrary call sites, this is the
+place.  For now though, create an empty struct:
+        struct dyn_arch_ftrace {
+                /* No extra data needed */
+        };
+With the header out of the way, we can fill out the assembly code.  While we
+did already create a mcount() function earlier, dynamic ftrace only wants a
+stub function.  This is because the mcount() will only be used during boot
+and then all references to it will be patched out never to return.  Instead,
+the guts of the old mcount() will be used to create a new ftrace_caller()
+function.  Because the two are hard to merge, it will most likely be a lot
+easier to have two separate definitions split up by #ifdefs.  Same goes for
+the ftrace_stub() as that will now be inlined in ftrace_caller().
+Before we get confused anymore, let's check out some pseudo code so you can
+implement your own stuff in assembly:
-HAVE_DYNAMIC_FTRACE
+void mcount(void)
---------------------
+{
+        return;
+}
+void ftrace_caller(void)
+{
+        /* implement HAVE_FUNCTION_TRACE_MCOUNT_TEST if you desire */
+        /* save all state needed by the ABI (see paragraph above) */
+        unsigned long frompc = ...;
+        unsigned long selfpc = <return address> - MCOUNT_INSN_SIZE;
+ftrace_call:
+        ftrace_stub(frompc, selfpc);
+        /* restore all state needed by the ABI */
+ftrace_stub:
+        return;
+}
+This might look a little odd at first, but keep in mind that we will be runtime
+patching multiple things.  First, only functions that we actually want to trace
+will be patched to call ftrace_caller().  Second, since we only have one tracer
+active at a time, we will patch the ftrace_caller() function itself to call the
+specific tracer in question.  That is the point of the ftrace_call label.
+With that in mind, let's move on to the C code that will actually be doing the
+runtime patching.  You'll need a little knowledge of your arch's opcodes in
+order to make it through the next section.
+Every arch has an init callback function.  If you need to do something early on
+to initialize some state, this is the time to do that.  Otherwise, this simple
+function below should be sufficient for most people:
+int __init ftrace_dyn_arch_init(void *data)
+{
+        /* return value is done indirectly via data */
+        *(unsigned long *)data = 0;
+        return 0;
+}
+There are two functions that are used to do runtime patching of arbitrary
+functions.  The first is used to turn the mcount call site into a nop (which
+is what helps us retain runtime performance when not tracing).  The second is
+used to turn the mcount call site into a call to an arbitrary location (but
+typically that is ftracer_caller()).  See the general function definition in
+linux/ftrace.h for the functions:
+        ftrace_make_nop()
+        ftrace_make_call()
+The rec->ip value is the address of the mcount call site that was collected
+by the scripts/recordmcount.pl during build time.
+The last function is used to do runtime patching of the active tracer.  This
+will be modifying the assembly code at the location of the ftrace_call symbol
+inside of the ftrace_caller() function.  So you should have sufficient padding
+at that location to support the new function calls you'll be inserting.  Some
+people will be using a "call" type instruction while others will be using a
+"branch" type instruction.  Specifically, the function is:
+        ftrace_update_ftrace_func()
+HAVE_DYNAMIC_FTRACE + HAVE_FUNCTION_GRAPH_TRACER
+------------------------------------------------
+The function grapher needs a few tweaks in order to work with dynamic ftrace.
+Basically, you will need to:
+        - update:
+                - ftrace_caller()
+                - ftrace_graph_call()
+                - ftrace_graph_caller()
+        - implement:
+                - ftrace_enable_ftrace_graph_caller()
+                - ftrace_disable_ftrace_graph_caller()
 <details to be filled>
+Quick notes:
+        - add a nop stub after the ftrace_call location named ftrace_graph_call;
+          stub needs to be large enough to support a call to ftrace_graph_caller()
+        - update ftrace_graph_caller() to work with being called by the new
+          ftrace_caller() since some semantics may have changed
+        - ftrace_enable_ftrace_graph_caller() will runtime patch the
+          ftrace_graph_call location with a call to ftrace_graph_caller()
+        - ftrace_disable_ftrace_graph_caller() will runtime patch the
+          ftrace_graph_call location with nops

-                        kmemtrace - Kernel Memory Tracer
-                          by Eduard - Gabriel Munteanu
-                             <eduard.munteanu@linux360.ro>
-I. Introduction
-===============
-kmemtrace helps kernel developers figure out two things:
-1) how different allocators (SLAB, SLUB etc.) perform
-2) how kernel code allocates memory and how much
-To do this, we trace every allocation and export information to the userspace
-through the relay interface. We export things such as the number of requested
-bytes, the number of bytes actually allocated (i.e. including internal
-fragmentation), whether this is a slab allocation or a plain kmalloc() and so
-on.
-The actual analysis is performed by a userspace tool (see section III for
-details on where to get it from). It logs the data exported by the kernel,
-processes it and (as of writing this) can provide the following information:
- the total amount of memory allocated and fragmentation per call-site
- the amount of memory allocated and fragmentation per allocation
- total memory allocated and fragmentation in the collected dataset
- number of cross-CPU allocation and frees (makes sense in NUMA environments)
-Moreover, it can potentially find inconsistent and erroneous behavior in
-kernel code, such as using slab free functions on kmalloc'ed memory or
-allocating less memory than requested (but not truly failed allocations).
-kmemtrace also makes provisions for tracing on some arch and analysing the
-data on another.
-II. Design and goals
-====================
-kmemtrace was designed to handle rather large amounts of data. Thus, it uses
-the relay interface to export whatever is logged to userspace, which then
-stores it. Analysis and reporting is done asynchronously, that is, after the
-data is collected and stored. By design, it allows one to log and analyse
-on different machines and different arches.
-As of writing this, the ABI is not considered stable, though it might not
-change much. However, no guarantees are made about compatibility yet. When
-deemed stable, the ABI should still allow easy extension while maintaining
-backward compatibility. This is described further in Documentation/ABI.
-Summary of design goals:
-        - allow logging and analysis to be done across different machines
-        - be fast and anticipate usage in high-load environments (*)
-        - be reasonably extensible
-        - make it possible for GNU/Linux distributions to have kmemtrace
-        included in their repositories
-(*) - one of the reasons Pekka Enberg's original userspace data analysis
-    tool's code was rewritten from Perl to C (although this is more than a
-    simple conversion)
-III. Quick usage guide
-======================
-1) Get a kernel that supports kmemtrace and build it accordingly (i.e. enable
-CONFIG_KMEMTRACE).
-2) Get the userspace tool and build it:
-$ git clone git://repo.or.cz/kmemtrace-user.git         # current repository
-$ cd kmemtrace-user/
-$ ./autogen.sh
-$ ./configure
-$ make
-3) Boot the kmemtrace-enabled kernel if you haven't, preferably in the
-'single' runlevel (so that relay buffers don't fill up easily), and run
-kmemtrace:
-# '$' does not mean user, but root here.
-$ mount -t debugfs none /sys/kernel/debug
-$ mount -t proc none /proc
-$ cd path/to/kmemtrace-user/
-$ ./kmemtraced
-Wait a bit, then stop it with CTRL+C.
-$ cat /sys/kernel/debug/kmemtrace/total_overruns        # Check if we didn't
-                                                        # overrun, should
-                                                        # be zero.
-$ (Optionally) [Run kmemtrace_check separately on each cpu[0-9]*.out file to
-                check its correctness]
-$ ./kmemtrace-report
-Now you should have a nice and short summary of how the allocator performs.
-IV. FAQ and known issues
-========================
-Q: 'cat /sys/kernel/debug/kmemtrace/total_overruns' is non-zero, how do I fix
-this? Should I worry?
-A: If it's non-zero, this affects kmemtrace's accuracy, depending on how
-large the number is. You can fix it by supplying a higher
-'kmemtrace.subbufs=N' kernel parameter.
---
-Q: kmemtrace_check reports errors, how do I fix this? Should I worry?
-A: This is a bug and should be reported. It can occur for a variety of
-reasons:
-        - possible bugs in relay code
-        - possible misuse of relay by kmemtrace
-        - timestamps being collected unorderly
-Or you may fix it yourself and send us a patch.
---
-Q: kmemtrace_report shows many errors, how do I fix this? Should I worry?
-A: This is a known issue and I'm working on it. These might be true errors
-in kernel code, which may have inconsistent behavior (e.g. allocating memory
-with kmem_cache_alloc() and freeing it with kfree()). Pekka Enberg pointed
-out this behavior may work with SLAB, but may fail with other allocators.
-It may also be due to lack of tracing in some unusual allocator functions.
-We don't want bug reports regarding this issue yet.

+# This is a POC for reading the text representation of trace output related to
+# page reclaim. It makes an attempt to extract some high-level information on
+# what is going on. The accuracy of the parser may vary
+#
+# Example usage: trace-vmscan-postprocess.pl < /sys/kernel/debug/tracing/trace_pipe
+# other options
+#   --read-procstat     If the trace lacks process info, get it from /proc
+#   --ignore-pid        Aggregate processes of the same name together

+* Overview
+The Multifunction Composite Gadget (or g_multi) is a composite gadget
+that makes extensive use of the composite framework to provide
+a... multifunction gadget.
+In it's standard configuration it provides a single USB configuration
+with RNDIS[1] (that is Ethernet), USB CDC[2] ACM (that is serial) and
+USB Mass Storage functions.
+A CDC ECM (Ethernet) function may be turned on via a Kconfig option
+and RNDIS can be turned off.  If they are both enabled the gadget will
+have two configurations -- one with RNDIS and another with CDC ECM[3].
+Please not that if you use non-standard configuration (that is enable
+CDC ECM) you may need to change vendor and/or product ID.
+* Host drivers
+To make use of the gadget one needs to make it work on host side --
+without that there's no hope of achieving anything with the gadget.
+As one might expect, things one need to do very from system to system.
+** Linux host drivers
+Since the gadget uses standard composite framework and appears as such
+to Linux host it does not need any additional drivers on Linux host
+side.  All the functions are handled by respective drivers developed
+for them.
+This is also true for two configuration set-up with RNDIS
+configuration being the first one.  Linux host will use the second
+configuration with CDC ECM which should work better under Linux.
+** Windows host drivers
+For the gadget two work under Windows two conditions have to be met:
+*** Detecting as composite gadget
+First of all, Windows need to detect the gadget as an USB composite
+gadget which on its own have some conditions[4].  If they are met,
+Windows lets USB Generic Parent Driver[5] handle the device which then
+tries to much drivers for each individual interface (sort of, don't
+get into too many details).
+The good news is: you do not have to worry about most of the
+conditions!
+The only thing to worry is that the gadget has to have a single
+configuration so a dual RNDIS and CDC ECM gadget won't work unless you
+create a proper INF -- and of course, if you do submit it!
+*** Installing drivers for each function
+The other, trickier thing is making Windows install drivers for each
+individual function.
+For mass storage it is trivial since Windows detect it's an interface
+implementing USB Mass Storage class and selects appropriate driver.
+Things are harder with RDNIS and CDC ACM.
+**** RNDIS
+To make Windows select RNDIS drivers for the first function in the
+gadget, one needs to use the [[file:linux.inf]] file provided with this
+document.  It "attaches" Window's RNDIS driver to the first interface
+of the gadget.
+Please note, that while testing we encountered some issues[6] when
+RNDIS was not the first interface.  You do not need to worry abut it
+unless you are trying to develop your own gadget in which case watch
+out for this bug.
+**** CDC ACM
+Similarly, [[file:linux-cdc-acm.inf]] is provided for CDC ACM.
+**** Customising the gadget
+If you intend to hack the g_multi gadget be advised that rearranging
+functions will obviously change interface numbers for each of the
+functionality.  As an effect provided INFs won't work since they have
+interface numbers hard-coded in them (it's not hard to change those
+though[7]).
+This also means, that after experimenting with g_multi and changing
+provided functions one should change gadget's vendor and/or product ID
+so there will be no collision with other customised gadgets or the
+original gadget.
+Failing to comply may cause brain damage after wondering for hours why
+things don't work as intended before realising Windows have cached
+some drivers information (changing USB port may sometimes help plus
+you might try using USBDeview[8] to remove the phantom device).
+**** INF testing
+Provided INF files have been tested on Windows XP SP3, Windows Vista
+and Windows 7, all 32-bit versions.  It should work on 64-bit versions
+as well.  It most likely won't work on Windows prior to Windows XP
+SP2.
+** Other systems
+At this moment, drivers for any other systems have not been tested.
+Knowing how MacOS is based on BSD and BSD is an Open Source it is
+believed that it should (read: "I have no idea whether it will") work
+out-of-the-box.
+For more exotic systems I have even less to say...
+Any testing and drivers *are* *welcome*!
+* Authors
+This document has been written by Michal Nazarewicz
+([[mailto:mina86@mina86.com]]).  INF files have been hacked with
+support of Marek Szyprowski ([[mailto:m.szyprowski@samsung.com]]) and
+Xiaofan Chen ([[mailto:xiaofanc@gmail.com]]) basing on the MS RNDIS
+template[9], Microchip's CDC ACM INF file and David Brownell's
+([[mailto:dbrownell@users.sourceforge.net]]) original INF files.

+Introduction
+============
+The V4L2 control API seems simple enough, but quickly becomes very hard to
+implement correctly in drivers. But much of the code needed to handle controls
+is actually not driver specific and can be moved to the V4L core framework.
+After all, the only part that a driver developer is interested in is:
+1) How do I add a control?
+2) How do I set the control's value? (i.e. s_ctrl)
+And occasionally:
+3) How do I get the control's value? (i.e. g_volatile_ctrl)
+4) How do I validate the user's proposed control value? (i.e. try_ctrl)
+All the rest is something that can be done centrally.
+The control framework was created in order to implement all the rules of the
+V4L2 specification with respect to controls in a central place. And to make
+life as easy as possible for the driver developer.
+Note that the control framework relies on the presence of a struct v4l2_device
+for V4L2 drivers and struct v4l2_subdev for sub-device drivers.
+Objects in the framework
+========================
+There are two main objects:
+The v4l2_ctrl object describes the control properties and keeps track of the
+control's value (both the current value and the proposed new value).
+v4l2_ctrl_handler is the object that keeps track of controls. It maintains a
+list of v4l2_ctrl objects that it owns and another list of references to
+controls, possibly to controls owned by other handlers.
+Basic usage for V4L2 and sub-device drivers
+===========================================
+1) Prepare the driver:
+1.1) Add the handler to your driver's top-level struct:
+        struct foo_dev {
+                ...
+                struct v4l2_ctrl_handler ctrl_handler;
+                ...
+        };
+        struct foo_dev *foo;
+1.2) Initialize the handler:
+        v4l2_ctrl_handler_init(&foo->ctrl_handler, nr_of_controls);
+  The second argument is a hint telling the function how many controls this
+  handler is expected to handle. It will allocate a hashtable based on this
+  information. It is a hint only.
+1.3) Hook the control handler into the driver:
+1.3.1) For V4L2 drivers do this:
+        struct foo_dev {
+                ...
+                struct v4l2_device v4l2_dev;
+                ...
+                struct v4l2_ctrl_handler ctrl_handler;
+                ...
+        };
+        foo->v4l2_dev.ctrl_handler = &foo->ctrl_handler;
+  Where foo->v4l2_dev is of type struct v4l2_device.
+  Finally, remove all control functions from your v4l2_ioctl_ops:
+  vidioc_queryctrl, vidioc_querymenu, vidioc_g_ctrl, vidioc_s_ctrl,
+  vidioc_g_ext_ctrls, vidioc_try_ext_ctrls and vidioc_s_ext_ctrls.
+  Those are now no longer needed.
+1.3.2) For sub-device drivers do this:
+        struct foo_dev {
+                ...
+                struct v4l2_subdev sd;
+                ...
+                struct v4l2_ctrl_handler ctrl_handler;
+                ...
+        };
+        foo->sd.ctrl_handler = &foo->ctrl_handler;
+  Where foo->sd is of type struct v4l2_subdev.
+  And set all core control ops in your struct v4l2_subdev_core_ops to these
+  helpers:
+        .queryctrl = v4l2_subdev_queryctrl,
+        .querymenu = v4l2_subdev_querymenu,
+        .g_ctrl = v4l2_subdev_g_ctrl,
+        .s_ctrl = v4l2_subdev_s_ctrl,
+        .g_ext_ctrls = v4l2_subdev_g_ext_ctrls,
+        .try_ext_ctrls = v4l2_subdev_try_ext_ctrls,
+        .s_ext_ctrls = v4l2_subdev_s_ext_ctrls,
+  Note: this is a temporary solution only. Once all V4L2 drivers that depend
+  on subdev drivers are converted to the control framework these helpers will
+  no longer be needed.
+1.4) Clean up the handler at the end:
+        v4l2_ctrl_handler_free(&foo->ctrl_handler);
+2) Add controls:
+You add non-menu controls by calling v4l2_ctrl_new_std:
+        struct v4l2_ctrl *v4l2_ctrl_new_std(struct v4l2_ctrl_handler *hdl,
+                        const struct v4l2_ctrl_ops *ops,
+                        u32 id, s32 min, s32 max, u32 step, s32 def);
+Menu controls are added by calling v4l2_ctrl_new_std_menu:
+        struct v4l2_ctrl *v4l2_ctrl_new_std_menu(struct v4l2_ctrl_handler *hdl,
+                        const struct v4l2_ctrl_ops *ops,
+                        u32 id, s32 max, s32 skip_mask, s32 def);
+These functions are typically called right after the v4l2_ctrl_handler_init:
+        v4l2_ctrl_handler_init(&foo->ctrl_handler, nr_of_controls);
+        v4l2_ctrl_new_std(&foo->ctrl_handler, &foo_ctrl_ops,
+                        V4L2_CID_BRIGHTNESS, 0, 255, 1, 128);
+        v4l2_ctrl_new_std(&foo->ctrl_handler, &foo_ctrl_ops,
+                        V4L2_CID_CONTRAST, 0, 255, 1, 128);
+        v4l2_ctrl_new_std_menu(&foo->ctrl_handler, &foo_ctrl_ops,
+                        V4L2_CID_POWER_LINE_FREQUENCY,
+                        V4L2_CID_POWER_LINE_FREQUENCY_60HZ, 0,
+                        V4L2_CID_POWER_LINE_FREQUENCY_DISABLED);
+        ...
+        if (foo->ctrl_handler.error) {
+                int err = foo->ctrl_handler.error;
+                v4l2_ctrl_handler_free(&foo->ctrl_handler);
+                return err;
+        }
+The v4l2_ctrl_new_std function returns the v4l2_ctrl pointer to the new
+control, but if you do not need to access the pointer outside the control ops,
+then there is no need to store it.
+The v4l2_ctrl_new_std function will fill in most fields based on the control
+ID except for the min, max, step and default values. These are passed in the
+last four arguments. These values are driver specific while control attributes
+like type, name, flags are all global. The control's current value will be set
+to the default value.
+The v4l2_ctrl_new_std_menu function is very similar but it is used for menu
+controls. There is no min argument since that is always 0 for menu controls,
+and instead of a step there is a skip_mask argument: if bit X is 1, then menu
+item X is skipped.
+Note that if something fails, the function will return NULL or an error and
+set ctrl_handler->error to the error code. If ctrl_handler->error was already
+set, then it will just return and do nothing. This is also true for
+v4l2_ctrl_handler_init if it cannot allocate the internal data structure.
+This makes it easy to init the handler and just add all controls and only check
+the error code at the end. Saves a lot of repetitive error checking.
+It is recommended to add controls in ascending control ID order: it will be
+a bit faster that way.
+3) Optionally force initial control setup:
+        v4l2_ctrl_handler_setup(&foo->ctrl_handler);
+This will call s_ctrl for all controls unconditionally. Effectively this
+initializes the hardware to the default control values. It is recommended
+that you do this as this ensures that both the internal data structures and
+the hardware are in sync.
+4) Finally: implement the v4l2_ctrl_ops
+        static const struct v4l2_ctrl_ops foo_ctrl_ops = {
+                .s_ctrl = foo_s_ctrl,
+        };
+Usually all you need is s_ctrl:
+        static int foo_s_ctrl(struct v4l2_ctrl *ctrl)
+        {
+                struct foo *state = container_of(ctrl->handler, struct foo, ctrl_handler);
+                switch (ctrl->id) {
+                case V4L2_CID_BRIGHTNESS:
+                        write_reg(0x123, ctrl->val);
+                        break;
+                case V4L2_CID_CONTRAST:
+                        write_reg(0x456, ctrl->val);
+                        break;
+                }
+                return 0;
+        }
+The control ops are called with the v4l2_ctrl pointer as argument.
+The new control value has already been validated, so all you need to do is
+to actually update the hardware registers.
+You're done! And this is sufficient for most of the drivers we have. No need
+to do any validation of control values, or implement QUERYCTRL/QUERYMENU. And
+G/S_CTRL as well as G/TRY/S_EXT_CTRLS are automatically supported.
+==============================================================================
+The remainder of this document deals with more advanced topics and scenarios.
+In practice the basic usage as described above is sufficient for most drivers.
+===============================================================================
+Inheriting Controls
+===================
+When a sub-device is registered with a V4L2 driver by calling
+v4l2_device_register_subdev() and the ctrl_handler fields of both v4l2_subdev
+and v4l2_device are set, then the controls of the subdev will become
+automatically available in the V4L2 driver as well. If the subdev driver
+contains controls that already exist in the V4L2 driver, then those will be
+skipped (so a V4L2 driver can always override a subdev control).
+What happens here is that v4l2_device_register_subdev() calls
+v4l2_ctrl_add_handler() adding the controls of the subdev to the controls
+of v4l2_device.
+Accessing Control Values
+========================
+The v4l2_ctrl struct contains these two unions:
+        /* The current control value. */
+        union {
+                s32 val;
+                s64 val64;
+                char *string;
+        } cur;
+        /* The new control value. */
+        union {
+                s32 val;
+                s64 val64;
+                char *string;
+        };
+Within the control ops you can freely use these. The val and val64 speak for
+themselves. The string pointers point to character buffers of length
+ctrl->maximum + 1, and are always 0-terminated.
+In most cases 'cur' contains the current cached control value. When you create
+a new control this value is made identical to the default value. After calling
+v4l2_ctrl_handler_setup() this value is passed to the hardware. It is generally
+a good idea to call this function.
+Whenever a new value is set that new value is automatically cached. This means
+that most drivers do not need to implement the g_volatile_ctrl() op. The
+exception is for controls that return a volatile register such as a signal
+strength read-out that changes continuously. In that case you will need to
+implement g_volatile_ctrl like this:
+        static int foo_g_volatile_ctrl(struct v4l2_ctrl *ctrl)
+        {
+                switch (ctrl->id) {
+                case V4L2_CID_BRIGHTNESS:
+                        ctrl->cur.val = read_reg(0x123);
+                        break;
+                }
+        }
+The 'new value' union is not used in g_volatile_ctrl. In general controls
+that need to implement g_volatile_ctrl are read-only controls.
+To mark a control as volatile you have to set the is_volatile flag:
+        ctrl = v4l2_ctrl_new_std(&sd->ctrl_handler, ...);
+        if (ctrl)
+                ctrl->is_volatile = 1;
+For try/s_ctrl the new values (i.e. as passed by the user) are filled in and
+you can modify them in try_ctrl or set them in s_ctrl. The 'cur' union
+contains the current value, which you can use (but not change!) as well.
+If s_ctrl returns 0 (OK), then the control framework will copy the new final
+values to the 'cur' union.
+While in g_volatile/s/try_ctrl you can access the value of all controls owned
+by the same handler since the handler's lock is held. If you need to access
+the value of controls owned by other handlers, then you have to be very careful
+not to introduce deadlocks.
+Outside of the control ops you have to go through to helper functions to get
+or set a single control value safely in your driver:
+        s32 v4l2_ctrl_g_ctrl(struct v4l2_ctrl *ctrl);
+        int v4l2_ctrl_s_ctrl(struct v4l2_ctrl *ctrl, s32 val);
+These functions go through the control framework just as VIDIOC_G/S_CTRL ioctls
+do. Don't use these inside the control ops g_volatile/s/try_ctrl, though, that
+will result in a deadlock since these helpers lock the handler as well.
+You can also take the handler lock yourself:
+        mutex_lock(&state->ctrl_handler.lock);
+        printk(KERN_INFO "String value is '%s'\n", ctrl1->cur.string);
+        printk(KERN_INFO "Integer value is '%s'\n", ctrl2->cur.val);
+        mutex_unlock(&state->ctrl_handler.lock);
+Menu Controls
+=============
+The v4l2_ctrl struct contains this union:
+        union {
+                u32 step;
+                u32 menu_skip_mask;
+        };
+For menu controls menu_skip_mask is used. What it does is that it allows you
+to easily exclude certain menu items. This is used in the VIDIOC_QUERYMENU
+implementation where you can return -EINVAL if a certain menu item is not
+present. Note that VIDIOC_QUERYCTRL always returns a step value of 1 for
+menu controls.
+A good example is the MPEG Audio Layer II Bitrate menu control where the
+menu is a list of standardized possible bitrates. But in practice hardware
+implementations will only support a subset of those. By setting the skip
+mask you can tell the framework which menu items should be skipped. Setting
+it to 0 means that all menu items are supported.
+You set this mask either through the v4l2_ctrl_config struct for a custom
+control, or by calling v4l2_ctrl_new_std_menu().
+Custom Controls
+===============
+Driver specific controls can be created using v4l2_ctrl_new_custom():
+        static const struct v4l2_ctrl_config ctrl_filter = {
+                .ops = &ctrl_custom_ops,
+                .id = V4L2_CID_MPEG_CX2341X_VIDEO_SPATIAL_FILTER,
+                .name = "Spatial Filter",
+                .type = V4L2_CTRL_TYPE_INTEGER,
+                .flags = V4L2_CTRL_FLAG_SLIDER,
+                .max = 15,
+                .step = 1,
+        };
+        ctrl = v4l2_ctrl_new_custom(&foo->ctrl_handler, &ctrl_filter, NULL);
+The last argument is the priv pointer which can be set to driver-specific
+private data.
+The v4l2_ctrl_config struct also has fields to set the is_private and is_volatile
+flags.
+If the name field is not set, then the framework will assume this is a standard
+control and will fill in the name, type and flags fields accordingly.
+Active and Grabbed Controls
+===========================
+If you get more complex relationships between controls, then you may have to
+activate and deactivate controls. For example, if the Chroma AGC control is
+on, then the Chroma Gain control is inactive. That is, you may set it, but
+the value will not be used by the hardware as long as the automatic gain
+control is on. Typically user interfaces can disable such input fields.
+You can set the 'active' status using v4l2_ctrl_activate(). By default all
+controls are active. Note that the framework does not check for this flag.
+It is meant purely for GUIs. The function is typically called from within
+s_ctrl.
+The other flag is the 'grabbed' flag. A grabbed control means that you cannot
+change it because it is in use by some resource. Typical examples are MPEG
+bitrate controls that cannot be changed while capturing is in progress.
+If a control is set to 'grabbed' using v4l2_ctrl_grab(), then the framework
+will return -EBUSY if an attempt is made to set this control. The
+v4l2_ctrl_grab() function is typically called from the driver when it
+starts or stops streaming.
+Control Clusters
+================
+By default all controls are independent from the others. But in more
+complex scenarios you can get dependencies from one control to another.
+In that case you need to 'cluster' them:
+        struct foo {
+                struct v4l2_ctrl_handler ctrl_handler;
+#define AUDIO_CL_VOLUME (0)
+#define AUDIO_CL_MUTE   (1)
+                struct v4l2_ctrl *audio_cluster[2];
+                ...
+        };
+        state->audio_cluster[AUDIO_CL_VOLUME] =
+                v4l2_ctrl_new_std(&state->ctrl_handler, ...);
+        state->audio_cluster[AUDIO_CL_MUTE] =
+                v4l2_ctrl_new_std(&state->ctrl_handler, ...);
+        v4l2_ctrl_cluster(ARRAY_SIZE(state->audio_cluster), state->audio_cluster);
+From now on whenever one or more of the controls belonging to the same
+cluster is set (or 'gotten', or 'tried'), only the control ops of the first
+control ('volume' in this example) is called. You effectively create a new
+composite control. Similar to how a 'struct' works in C.
+So when s_ctrl is called with V4L2_CID_AUDIO_VOLUME as argument, you should set
+all two controls belonging to the audio_cluster:
+        static int foo_s_ctrl(struct v4l2_ctrl *ctrl)
+        {
+                struct foo *state = container_of(ctrl->handler, struct foo, ctrl_handler);
+                switch (ctrl->id) {
+                case V4L2_CID_AUDIO_VOLUME: {
+                        struct v4l2_ctrl *mute = ctrl->cluster[AUDIO_CL_MUTE];
+                        write_reg(0x123, mute->val ? 0 : ctrl->val);
+                        break;
+                }
+                case V4L2_CID_CONTRAST:
+                        write_reg(0x456, ctrl->val);
+                        break;
+                }
+                return 0;
+        }
+In the example above the following are equivalent for the VOLUME case:
+        ctrl == ctrl->cluster[AUDIO_CL_VOLUME] == state->audio_cluster[AUDIO_CL_VOLUME]
+        ctrl->cluster[AUDIO_CL_MUTE] == state->audio_cluster[AUDIO_CL_MUTE]
+Note that controls in a cluster may be NULL. For example, if for some
+reason mute was never added (because the hardware doesn't support that
+particular feature), then mute will be NULL. So in that case we have a
+cluster of 2 controls, of which only 1 is actually instantiated. The
+only restriction is that the first control of the cluster must always be
+present, since that is the 'master' control of the cluster. The master
+control is the one that identifies the cluster and that provides the
+pointer to the v4l2_ctrl_ops struct that is used for that cluster.
+Obviously, all controls in the cluster array must be initialized to either
+a valid control or to NULL.
+VIDIOC_LOG_STATUS Support
+=========================
+This ioctl allow you to dump the current status of a driver to the kernel log.
+The v4l2_ctrl_handler_log_status(ctrl_handler, prefix) can be used to dump the
+value of the controls owned by the given handler to the log. You can supply a
+prefix as well. If the prefix didn't end with a space, then ': ' will be added
+for you.
+Different Handlers for Different Video Nodes
+============================================
+Usually the V4L2 driver has just one control handler that is global for
+all video nodes. But you can also specify different control handlers for
+different video nodes. You can do that by manually setting the ctrl_handler
+field of struct video_device.
+That is no problem if there are no subdevs involved but if there are, then
+you need to block the automatic merging of subdev controls to the global
+control handler. You do that by simply setting the ctrl_handler field in
+struct v4l2_device to NULL. Now v4l2_device_register_subdev() will no longer
+merge subdev controls.
+After each subdev was added, you will then have to call v4l2_ctrl_add_handler
+manually to add the subdev's control handler (sd->ctrl_handler) to the desired
+control handler. This control handler may be specific to the video_device or
+for a subset of video_device's. For example: the radio device nodes only have
+audio controls, while the video and vbi device nodes share the same control
+handler for the audio and video controls.
+If you want to have one handler (e.g. for a radio device node) have a subset
+of another handler (e.g. for a video device node), then you should first add
+the controls to the first handler, add the other controls to the second
+handler and finally add the first handler to the second. For example:
+        v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_VOLUME, ...);
+        v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...);
+        v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...);
+        v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...);
+        v4l2_ctrl_add_handler(&video_ctrl_handler, &radio_ctrl_handler);
+Or you can add specific controls to a handler:
+        volume = v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_AUDIO_VOLUME, ...);
+        v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_BRIGHTNESS, ...);
+        v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_CONTRAST, ...);
+        v4l2_ctrl_add_ctrl(&radio_ctrl_handler, volume);
+What you should not do is make two identical controls for two handlers.
+For example:
+        v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...);
+        v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_AUDIO_MUTE, ...);
+This would be bad since muting the radio would not change the video mute
+control. The rule is to have one control for each hardware 'knob' that you
+can twiddle.
+Finding Controls
+================
+Normally you have created the controls yourself and you can store the struct
+v4l2_ctrl pointer into your own struct.
+But sometimes you need to find a control from another handler that you do
+not own. For example, if you have to find a volume control from a subdev.
+You can do that by calling v4l2_ctrl_find:
+        struct v4l2_ctrl *volume;
+        volume = v4l2_ctrl_find(sd->ctrl_handler, V4L2_CID_AUDIO_VOLUME);
+Since v4l2_ctrl_find will lock the handler you have to be careful where you
+use it. For example, this is not a good idea:
+        struct v4l2_ctrl_handler ctrl_handler;
+        v4l2_ctrl_new_std(&ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...);
+        v4l2_ctrl_new_std(&ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...);
+...and in video_ops.s_ctrl:
+        case V4L2_CID_BRIGHTNESS:
+                contrast = v4l2_find_ctrl(&ctrl_handler, V4L2_CID_CONTRAST);
+                ...
+When s_ctrl is called by the framework the ctrl_handler.lock is already taken, so
+attempting to find another control from the same handler will deadlock.
+It is recommended not to use this function from inside the control ops.
+Inheriting Controls
+===================
+When one control handler is added to another using v4l2_ctrl_add_handler, then
+by default all controls from one are merged to the other. But a subdev might
+have low-level controls that make sense for some advanced embedded system, but
+not when it is used in consumer-level hardware. In that case you want to keep
+those low-level controls local to the subdev. You can do this by simply
+setting the 'is_private' flag of the control to 1:
+        static const struct v4l2_ctrl_config ctrl_private = {
+                .ops = &ctrl_custom_ops,
+                .id = V4L2_CID_...,
+                .name = "Some Private Control",
+                .type = V4L2_CTRL_TYPE_INTEGER,
+                .max = 15,
+                .step = 1,
+                .is_private = 1,
+        };
+        ctrl = v4l2_ctrl_new_custom(&foo->ctrl_handler, &ctrl_private, NULL);
+These controls will now be skipped when v4l2_ctrl_add_handler is called.
+V4L2_CTRL_TYPE_CTRL_CLASS Controls
+==================================
+Controls of this type can be used by GUIs to get the name of the control class.
+A fully featured GUI can make a dialog with multiple tabs with each tab
+containing the controls belonging to a particular control class. The name of
+each tab can be found by querying a special control with ID <control class | 1>.
+Drivers do not have to care about this. The framework will automatically add
+a control of this type whenever the first control belonging to a new control
+class is added.
+Differences from the Spec
+=========================
+There are a few places where the framework acts slightly differently from the
+V4L2 Specification. Those differences are described in this section. We will
+have to see whether we need to adjust the spec or not.
+1) It is no longer required to have all controls contained in a
+v4l2_ext_control array be from the same control class. The framework will be
+able to handle any type of control in the array. You need to set ctrl_class
+to 0 in order to enable this. If ctrl_class is non-zero, then it will still
+check that all controls belong to that control class.
+If you set ctrl_class to 0 and count to 0, then it will only return an error
+if there are no controls at all.
+2) Clarified the way error_idx works. For get and set it will be equal to
+count if nothing was done yet. If it is less than count then only the controls
+up to error_idx-1 were successfully applied.
+3) When attempting to read a button control the framework will return -EACCES
+instead of -EINVAL as stated in the spec. It seems to make more sense since
+button controls are write-only controls.
+4) Attempting to write to a read-only control will return -EACCES instead of
+-EINVAL as the spec says.
+5) The spec does not mention what should happen when you try to set/get a
+control class controls. ivtv currently returns -EINVAL (indicating that the
+control ID does not exist) while the framework will return -EACCES, which
+makes more sense.
+Proposals for Extensions
+========================
+Some ideas for future extensions to the spec:
+1) Add a V4L2_CTRL_FLAG_HEX to have values shown as hexadecimal instead of
+decimal. Useful for e.g. video_mute_yuv.
+2) It is possible to mark in the controls array which controls have been
+successfully written and which failed by for example adding a bit to the
+control ID. Not sure if it is worth the effort, though.
+3) Trying to set volatile inactive controls should result in -EACCESS.
+4) Add a new flag to mark volatile controls. Any application that wants
+to store the state of the controls can then skip volatile inactive controls.
+Currently it is not possible to detect such controls.
