18+Overview
19+
20+DESCRIPTION
21+
22+SEC 4 h/w can process requests from 2 types of sources.
23+1. DPAA Queue Interface (HW interface between Queue Manager & SEC 4).
24+2. Job Rings (HW interface between cores & SEC 4 registers).
25+
26+High Speed Data Path Configuration:
27+
28+HW interface between QM & SEC 4 and also BM & SEC 4, on DPAA-enabled parts
29+such as the P4080. The number of simultaneous dequeues the QI can make is
30+equal to the number of Descriptor Controller (DECO) engines in a particular
31+SEC version. E.g., the SEC 4.0 in the P4080 has 5 DECOs and can thus
32+dequeue from 5 subportals simultaneously.
33+
34+Job Ring Data Path Configuration:
35+
36+Each JR is located on a separate 4k page, they may (or may not) be made visible
37+in the memory partition devoted to a particular core. The P4080 has 4 JRs, so
38+up to 4 JRs can be configured; and all 4 JRs process requests in parallel.

10+CPI Clock- Can Protocol Interface Clock
11+ This CLK_SRC bit of CTRL(control register) selects the clock source to
12+ the CAN Protocol Interface(CPI) to be either the peripheral clock
13+ (driven by the PLL) or the crystal oscillator clock. The selected clock
14+ is the one fed to the prescaler to generate the Serial Clock (Sclock).
15+ The PRESDIV field of CTRL(control register) controls a prescaler that
16+ generates the Serial Clock (Sclock), whose period defines the
17+ time quantum used to compose the CAN waveform.
18+

78+* Gianfar PTP clock nodes
79+
80+General Properties:
81+
82+ - compatible Should be "fsl,etsec-ptp"
83+ - reg Offset and length of the register set for the device
84+ - interrupts There should be at least two interrupts. Some devices
85+ have as many as four PTP related interrupts.
86+
87+Clock Properties:
88+
89+ - fsl,tclk-period Timer reference clock period in nanoseconds.
90+ - fsl,tmr-prsc Prescaler, divides the output clock.
91+ - fsl,tmr-add Frequency compensation value.
92+ - fsl,tmr-fiper1 Fixed interval period pulse generator.
93+ - fsl,tmr-fiper2 Fixed interval period pulse generator.
94+ - fsl,max-adj Maximum frequency adjustment in parts per billion.
95+
96+ These properties set the operational parameters for the PTP
97+ clock. You must choose these carefully for the clock to work right.
98+ Here is how to figure good values:
99+
100+ TimerOsc = system clock MHz
101+ tclk_period = desired clock period nanoseconds
102+ NominalFreq = 1000 / tclk_period MHz
103+ FreqDivRatio = TimerOsc / NominalFreq (must be greater that 1.0)
104+ tmr_add = ceil(2^32 / FreqDivRatio)
105+ OutputClock = NominalFreq / tmr_prsc MHz
106+ PulseWidth = 1 / OutputClock microseconds
107+ FiperFreq1 = desired frequency in Hz
108+ FiperDiv1 = 1000000 * OutputClock / FiperFreq1
109+ tmr_fiper1 = tmr_prsc * tclk_period * FiperDiv1 - tclk_period
110+ max_adj = 1000000000 * (FreqDivRatio - 1.0) - 1
111+
112+ The calculation for tmr_fiper2 is the same as for tmr_fiper1. The
113+ driver expects that tmr_fiper1 will be correctly set to produce a 1
114+ Pulse Per Second (PPS) signal, since this will be offered to the PPS
115+ subsystem to synchronize the Linux clock.
116+
117+Example:
118+
119+ ptp_clock@24E00 {

1+ DMA Engine API Guide
2+ ====================
3+
4+ Vinod Koul <vinod dot koul at intel.com>
5+
6+NOTE: For DMA Engine usage in async_tx please see:
7+ Documentation/crypto/async-tx-api.txt
8+
9+
10+Below is a guide to device driver writers on how to use the Slave-DMA API of the
11+DMA Engine. This is applicable only for slave DMA usage only.
12+
13+The slave DMA usage consists of following steps
14+1. Allocate a DMA slave channel
15+2. Set slave and controller specific parameters
16+3. Get a descriptor for transaction
17+4. Submit the transaction and wait for callback notification
18+
19+1. Allocate a DMA slave channel
20+Channel allocation is slightly different in the slave DMA context, client
21+drivers typically need a channel from a particular DMA controller only and even
22+in some cases a specific channel is desired. To request a channel
23+dma_request_channel() API is used.
24+
25+Interface:
26+struct dma_chan *dma_request_channel(dma_cap_mask_t mask,
27+ dma_filter_fn filter_fn,
28+ void *filter_param);
29+where dma_filter_fn is defined as:
30+typedef bool (*dma_filter_fn)(struct dma_chan *chan, void *filter_param);
31+
32+When the optional 'filter_fn' parameter is set to NULL dma_request_channel
33+simply returns the first channel that satisfies the capability mask. Otherwise,
34+when the mask parameter is insufficient for specifying the necessary channel,
35+the filter_fn routine can be used to disposition the available channels in the
36+system. The filter_fn routine is called once for each free channel in the
37+system. Upon seeing a suitable channel filter_fn returns DMA_ACK which flags
38+that channel to be the return value from dma_request_channel. A channel
39+allocated via this interface is exclusive to the caller, until
40+dma_release_channel() is called.
41+
42+2. Set slave and controller specific parameters
43+Next step is always to pass some specific information to the DMA driver. Most of
44+the generic information which a slave DMA can use is in struct dma_slave_config.
45+It allows the clients to specify DMA direction, DMA addresses, bus widths, DMA
46+burst lengths etc. If some DMA controllers have more parameters to be sent then
47+they should try to embed struct dma_slave_config in their controller specific
48+structure. That gives flexibility to client to pass more parameters, if
49+required.
50+
51+Interface:
52+int dmaengine_slave_config(struct dma_chan *chan,
53+ struct dma_slave_config *config)
54+
55+3. Get a descriptor for transaction
56+For slave usage the various modes of slave transfers supported by the
57+DMA-engine are:
58+slave_sg - DMA a list of scatter gather buffers from/to a peripheral
59+dma_cyclic - Perform a cyclic DMA operation from/to a peripheral till the
60+ operation is explicitly stopped.
61+The non NULL return of this transfer API represents a "descriptor" for the given
62+transaction.
63+
64+Interface:
65+struct dma_async_tx_descriptor *(*chan->device->device_prep_dma_sg)(
66+ struct dma_chan *chan,
67+ struct scatterlist *dst_sg, unsigned int dst_nents,
68+ struct scatterlist *src_sg, unsigned int src_nents,
69+ unsigned long flags);
70+struct dma_async_tx_descriptor *(*chan->device->device_prep_dma_cyclic)(
71+ struct dma_chan *chan, dma_addr_t buf_addr, size_t buf_len,
72+ size_t period_len, enum dma_data_direction direction);
73+
74+4. Submit the transaction and wait for callback notification
75+To schedule the transaction to be scheduled by dma device, the "descriptor"
76+returned in above (3) needs to be submitted.
77+To tell the dma driver that a transaction is ready to be serviced, the
78+descriptor->submit() callback needs to be invoked. This chains the descriptor to
79+the pending queue.
80+The transactions in the pending queue can be activated by calling the
81+issue_pending API. If channel is idle then the first transaction in queue is
82+started and subsequent ones queued up.
83+On completion of the DMA operation the next in queue is submitted and a tasklet
84+triggered. The tasklet would then call the client driver completion callback
85+routine for notification, if set.
86+Interface:
87+void dma_async_issue_pending(struct dma_chan *chan);
88+
89+==============================================================================
90+
91+Additional usage notes for dma driver writers
92+1/ Although DMA engine specifies that completion callback routines cannot submit
93+any new operations, but typically for slave DMA subsequent transaction may not
94+be available for submit prior to callback routine being called. This requirement
95+is not a requirement for DMA-slave devices. But they should take care to drop
96+the spin-lock they might be holding before calling the callback routine

1+ HIDRAW - Raw Access to USB and Bluetooth Human Interface Devices
2+ ==================================================================
3+
4+The hidraw driver provides a raw interface to USB and Bluetooth Human
5+Interface Devices (HIDs). It differs from hiddev in that reports sent and
6+received are not parsed by the HID parser, but are sent to and received from
7+the device unmodified.
8+
9+Hidraw should be used if the userspace application knows exactly how to
10+communicate with the hardware device, and is able to construct the HID
11+reports manually. This is often the case when making userspace drivers for
12+custom HID devices.
13+
14+Hidraw is also useful for communicating with non-conformant HID devices
15+which send and receive data in a way that is inconsistent with their report
16+descriptors. Because hiddev parses reports which are sent and received
17+through it, checking them against the device's report descriptor, such
18+communication with these non-conformant devices is impossible using hiddev.
19+Hidraw is the only alternative, short of writing a custom kernel driver, for
20+these non-conformant devices.
21+
22+A benefit of hidraw is that its use by userspace applications is independent
23+of the underlying hardware type. Currently, Hidraw is implemented for USB
24+and Bluetooth. In the future, as new hardware bus types are developed which
25+use the HID specification, hidraw will be expanded to add support for these
26+new bus types.
27+
28+Hidraw uses a dynamic major number, meaning that udev should be relied on to
29+create hidraw device nodes. Udev will typically create the device nodes
30+directly under /dev (eg: /dev/hidraw0). As this location is distribution-
31+and udev rule-dependent, applications should use libudev to locate hidraw
32+devices attached to the system. There is a tutorial on libudev with a
33+working example at:
34+ http://www.signal11.us/oss/udev/
35+
36+The HIDRAW API
37+---------------
38+
39+read()
40+-------
41+read() will read a queued report received from the HID device. On USB
42+devices, the reports read using read() are the reports sent from the device
43+on the INTERRUPT IN endpoint. By default, read() will block until there is
44+a report available to be read. read() can be made non-blocking, by passing
45+the O_NONBLOCK flag to open(), or by setting the O_NONBLOCK flag using
46+fcntl().
47+
48+On a device which uses numbered reports, the first byte of the returned data
49+will be the report number; the report data follows, beginning in the second
50+byte. For devices which do not use numbered reports, the report data
51+will begin at the first byte.
52+
53+write()
54+--------
55+The write() function will write a report to the device. For USB devices, if
56+the device has an INTERRUPT OUT endpoint, the report will be sent on that
57+endpoint. If it does not, the report will be sent over the control endpoint,
58+using a SET_REPORT transfer.
59+
60+The first byte of the buffer passed to write() should be set to the report
61+number. If the device does not use numbered reports, the first byte should
62+be set to 0. The report data itself should begin at the second byte.
63+
64+ioctl()
65+--------
66+Hidraw supports the following ioctls:
67+
68+HIDIOCGRDESCSIZE: Get Report Descriptor Size
69+This ioctl will get the size of the device's report descriptor.
70+
71+HIDIOCGRDESC: Get Report Descriptor
72+This ioctl returns the device's report descriptor using a
73+hidraw_report_descriptor struct. Make sure to set the size field of the
74+hidraw_report_descriptor struct to the size returned from HIDIOCGRDESCSIZE.
75+
76+HIDIOCGRAWINFO: Get Raw Info
77+This ioctl will return a hidraw_devinfo struct containing the bus type, the
78+vendor ID (VID), and product ID (PID) of the device. The bus type can be one
79+of:
80+ BUS_USB
81+ BUS_HIL
82+ BUS_BLUETOOTH
83+ BUS_VIRTUAL
84+which are defined in linux/input.h.
85+
86+HIDIOCGRAWNAME(len): Get Raw Name
87+This ioctl returns a string containing the vendor and product strings of
88+the device. The returned string is Unicode, UTF-8 encoded.
89+
90+HIDIOCGRAWPHYS(len): Get Physical Address
91+This ioctl returns a string representing the physical address of the device.
92+For USB devices, the string contains the physical path to the device (the
93+USB controller, hubs, ports, etc). For Bluetooth devices, the string
94+contains the hardware (MAC) address of the device.
95+
96+HIDIOCSFEATURE(len): Send a Feature Report
97+This ioctl will send a feature report to the device. Per the HID
98+specification, feature reports are always sent using the control endpoint.
99+Set the first byte of the supplied buffer to the report number. For devices
100+which do not use numbered reports, set the first byte to 0. The report data
101+begins in the second byte. Make sure to set len accordingly, to one more
102+than the length of the report (to account for the report number).
103+
104+HIDIOCGFEATURE(len): Get a Feature Report
105+This ioctl will request a feature report from the device using the control
106+endpoint. The first byte of the supplied buffer should be set to the report
107+number of the requested report. For devices which do not use numbered
108+reports, set the first byte to 0. The report will be returned starting at
109+the first byte of the buffer (ie: the report number is not returned).
110+
111+Example
112+---------
113+In samples/, find hid-example.c, which shows examples of read(), write(),
114+and all the ioctls for hidraw. The code may be used by anyone for any
115+purpose, and can serve as a starting point for developing applications using
116+hidraw.

29+Description
30+-----------
31+
32+The SHT10, SHT11, SHT15, SHT71, and SHT75 are humidity and temperature
33+sensors.
34+
35+The devices communicate using two GPIO lines.
36+
37+Supported resolutions for the measurements are 14 bits for temperature and 12
38+bits for humidity, or 12 bits for temperature and 8 bits for humidity.
39+
40+The humidity calibration coefficients are programmed into an OTP memory on the
41+chip. These coefficients are used to internally calibrate the signals from the
42+sensors. Disabling the reload of those coefficients allows saving 10ms for each
43+measurement and decrease power consumption, while loosing on precision.
44+
45+Some options may be set directly in the sht15_platform_data structure
46+or via sysfs attributes.
47+
48+Notes:
49+ * The regulator supply name is set to "vcc".
50+ * If a CRC validation fails, a soft reset command is sent, which resets
51+ status register to its hardware default value, but the driver will try to
52+ restore the previous device configuration.
53+

58+ set it to true to enable CRC validation of the readings (default to false).
59+* no_otp_reload:

1+ How to Get Your Patch Accepted Into the Hwmon Subsystem
2+ -------------------------------------------------------
3+
4+This text is is a collection of suggestions for people writing patches or
5+drivers for the hwmon subsystem. Following these suggestions will greatly
6+increase the chances of your change being accepted.
7+
8+
9+1. General
10+----------
11+
12+* It should be unnecessary to mention, but please read and follow
13+ Documentation/SubmitChecklist
14+ Documentation/SubmittingDrivers
15+ Documentation/SubmittingPatches
16+ Documentation/CodingStyle
17+
18+* If your patch generates checkpatch warnings, please refrain from explanations
19+ such as "I don't like that coding style". Keep in mind that each unnecessary
20+ warning helps hiding a real problem. If you don't like the kernel coding
21+ style, don't write kernel drivers.
22+
23+* Please test your patch thoroughly. We are not your test group.
24+ Sometimes a patch can not or not completely be tested because of missing
25+ hardware. In such cases, you should test-build the code on at least one
26+ architecture. If run-time testing was not achieved, it should be written
27+ explicitly below the patch header.
28+
29+* If your patch (or the driver) is affected by configuration options such as
30+ CONFIG_SMP or CONFIG_HOTPLUG, make sure it compiles for all configuration
31+ variants.
32+
33+
34+2. Adding functionality to existing drivers
35+-------------------------------------------
36+
37+* Make sure the documentation in Documentation/hwmon/<driver_name> is up to
38+ date.
39+
40+* Make sure the information in Kconfig is up to date.
41+
42+* If the added functionality requires some cleanup or structural changes, split
43+ your patch into a cleanup part and the actual addition. This makes it easier
44+ to review your changes, and to bisect any resulting problems.
45+
46+* Never mix bug fixes, cleanup, and functional enhancements in a single patch.
47+
48+
49+3. New drivers
50+--------------
51+
52+* Running your patch or driver file(s) through checkpatch does not mean its
53+ formatting is clean. If unsure about formatting in your new driver, run it
54+ through Lindent. Lindent is not perfect, and you may have to do some minor
55+ cleanup, but it is a good start.
56+
57+* Consider adding yourself to MAINTAINERS.
58+
59+* Document the driver in Documentation/hwmon/<driver_name>.
60+
61+* Add the driver to Kconfig and Makefile in alphabetical order.
62+
63+* Make sure that all dependencies are listed in Kconfig. For new drivers, it
64+ is most likely prudent to add a dependency on EXPERIMENTAL.
65+
66+* Avoid forward declarations if you can. Rearrange the code if necessary.
67+
68+* Avoid calculations in macros and macro-generated functions. While such macros
69+ may save a line or so in the source, it obfuscates the code and makes code
70+ review more difficult. It may also result in code which is more complicated
71+ than necessary. Use inline functions or just regular functions instead.
72+
73+* If the driver has a detect function, make sure it is silent. Debug messages
74+ and messages printed after a successful detection are acceptable, but it
75+ must not print messages such as "Chip XXX not found/supported".
76+
77+ Keep in mind that the detect function will run for all drivers supporting an
78+ address if a chip is detected on that address. Unnecessary messages will just
79+ pollute the kernel log and not provide any value.
80+
81+* Provide a detect function if and only if a chip can be detected reliably.
82+
83+* Avoid writing to chip registers in the detect function. If you have to write,
84+ only do it after you have already gathered enough data to be certain that the
85+ detection is going to be successful.
86+
87+ Keep in mind that the chip might not be what your driver believes it is, and
88+ writing to it might cause a bad misconfiguration.
89+
90+* Make sure there are no race conditions in the probe function. Specifically,
91+ completely initialize your chip first, then create sysfs entries and register
92+ with the hwmon subsystem.
93+
94+* Do not provide support for deprecated sysfs attributes.
95+
96+* Do not create non-standard attributes unless really needed. If you have to use
97+ non-standard attributes, or you believe you do, discuss it on the mailing list
98+ first. Either case, provide a detailed explanation why you need the
99+ non-standard attribute(s).
100+ Standard attributes are specified in Documentation/hwmon/sysfs-interface.
101+
102+* When deciding which sysfs attributes to support, look at the chip's
103+ capabilities. While we do not expect your driver to support everything the
104+ chip may offer, it should at least support all limits and alarms.
105+
106+* Last but not least, please check if a driver for your chip already exists
107+ before starting to write a new driver. Especially for temperature sensors,
108+ new chips are often variants of previously released chips. In some cases,
109+ a presumably new chip may simply have been relabeled.

1+The input protocol uses a map of types and codes to express input device values
2+to userspace. This document describes the types and codes and how and when they
3+may be used.
4+
5+A single hardware event generates multiple input events. Each input event
6+contains the new value of a single data item. A special event type, EV_SYN, is
7+used to separate input events into packets of input data changes occurring at
8+the same moment in time. In the following, the term "event" refers to a single
9+input event encompassing a type, code, and value.
10+
11+The input protocol is a stateful protocol. Events are emitted only when values
12+of event codes have changed. However, the state is maintained within the Linux
13+input subsystem; drivers do not need to maintain the state and may attempt to
14+emit unchanged values without harm. Userspace may obtain the current state of
15+event code values using the EVIOCG* ioctls defined in linux/input.h. The event
16+reports supported by a device are also provided by sysfs in
17+class/input/event*/device/capabilities/, and the properties of a device are
18+provided in class/input/event*/device/properties.
19+
20+Types:
21+==========
22+Types are groupings of codes under a logical input construct. Each type has a
23+set of applicable codes to be used in generating events. See the Codes section
24+for details on valid codes for each type.
25+
26+* EV_SYN:
27+ - Used as markers to separate events. Events may be separated in time or in
28+ space, such as with the multitouch protocol.
29+
30+* EV_KEY:
31+ - Used to describe state changes of keyboards, buttons, or other key-like
32+ devices.
33+
34+* EV_REL:
35+ - Used to describe relative axis value changes, e.g. moving the mouse 5 units
36+ to the left.
37+
38+* EV_ABS:
39+ - Used to describe absolute axis value changes, e.g. describing the
40+ coordinates of a touch on a touchscreen.
41+
42+* EV_MSC:
43+ - Used to describe miscellaneous input data that do not fit into other types.
44+
45+* EV_SW:
46+ - Used to describe binary state input switches.
47+
48+* EV_LED:
49+ - Used to turn LEDs on devices on and off.
50+
51+* EV_SND:
52+ - Used to output sound to devices.
53+
54+* EV_REP:
55+ - Used for autorepeating devices.
56+
57+* EV_FF:
58+ - Used to send force feedback commands to an input device.
59+
60+* EV_PWR:
61+ - A special type for power button and switch input.
62+
63+* EV_FF_STATUS:
64+ - Used to receive force feedback device status.
65+
66+Codes:
67+==========
68+Codes define the precise type of event.
69+
70+EV_SYN:
71+----------
72+EV_SYN event values are undefined. Their usage is defined only by when they are
73+sent in the evdev event stream.
74+
75+* SYN_REPORT:
76+ - Used to synchronize and separate events into packets of input data changes
77+ occurring at the same moment in time. For example, motion of a mouse may set
78+ the REL_X and REL_Y values for one motion, then emit a SYN_REPORT. The next
79+ motion will emit more REL_X and REL_Y values and send another SYN_REPORT.
80+
81+* SYN_CONFIG:
82+ - TBD
83+
84+* SYN_MT_REPORT:
85+ - Used to synchronize and separate touch events. See the
86+ multi-touch-protocol.txt document for more information.
87+
88+* SYN_DROPPED:
89+ - Used to indicate buffer overrun in the evdev client's event queue.
90+ Client should ignore all events up to and including next SYN_REPORT
91+ event and query the device (using EVIOCG* ioctls) to obtain its
92+ current state.
93+
94+EV_KEY:
95+----------
96+EV_KEY events take the form KEY_<name> or BTN_<name>. For example, KEY_A is used
97+to represent the 'A' key on a keyboard. When a key is depressed, an event with
98+the key's code is emitted with value 1. When the key is released, an event is
99+emitted with value 0. Some hardware send events when a key is repeated. These
100+events have a value of 2. In general, KEY_<name> is used for keyboard keys, and
101+BTN_<name> is used for other types of momentary switch events.
102+
103+A few EV_KEY codes have special meanings:
104+
105+* BTN_TOOL_<name>:
106+ - These codes are used in conjunction with input trackpads, tablets, and
107+ touchscreens. These devices may be used with fingers, pens, or other tools.
108+ When an event occurs and a tool is used, the corresponding BTN_TOOL_<name>
109+ code should be set to a value of 1. When the tool is no longer interacting
110+ with the input device, the BTN_TOOL_<name> code should be reset to 0. All
111+ trackpads, tablets, and touchscreens should use at least one BTN_TOOL_<name>
112+ code when events are generated.
113+
114+* BTN_TOUCH:
115+ BTN_TOUCH is used for touch contact. While an input tool is determined to be
116+ within meaningful physical contact, the value of this property must be set
117+ to 1. Meaningful physical contact may mean any contact, or it may mean
118+ contact conditioned by an implementation defined property. For example, a
119+ touchpad may set the value to 1 only when the touch pressure rises above a
120+ certain value. BTN_TOUCH may be combined with BTN_TOOL_<name> codes. For
121+ example, a pen tablet may set BTN_TOOL_PEN to 1 and BTN_TOUCH to 0 while the
122+ pen is hovering over but not touching the tablet surface.
123+
124+Note: For appropriate function of the legacy mousedev emulation driver,
125+BTN_TOUCH must be the first evdev code emitted in a synchronization frame.
126+
127+Note: Historically a touch device with BTN_TOOL_FINGER and BTN_TOUCH was
128+interpreted as a touchpad by userspace, while a similar device without
129+BTN_TOOL_FINGER was interpreted as a touchscreen. For backwards compatibility
130+with current userspace it is recommended to follow this distinction. In the
131+future, this distinction will be deprecated and the device properties ioctl
132+EVIOCGPROP, defined in linux/input.h, will be used to convey the device type.
133+
134+* BTN_TOOL_FINGER, BTN_TOOL_DOUBLETAP, BTN_TOOL_TRIPLETAP, BTN_TOOL_QUADTAP:
135+ - These codes denote one, two, three, and four finger interaction on a
136+ trackpad or touchscreen. For example, if the user uses two fingers and moves
137+ them on the touchpad in an effort to scroll content on screen,
138+ BTN_TOOL_DOUBLETAP should be set to value 1 for the duration of the motion.
139+ Note that all BTN_TOOL_<name> codes and the BTN_TOUCH code are orthogonal in
140+ purpose. A trackpad event generated by finger touches should generate events
141+ for one code from each group. At most only one of these BTN_TOOL_<name>
142+ codes should have a value of 1 during any synchronization frame.
143+
144+Note: Historically some drivers emitted multiple of the finger count codes with
145+a value of 1 in the same synchronization frame. This usage is deprecated.
146+
147+Note: In multitouch drivers, the input_mt_report_finger_count() function should
148+be used to emit these codes. Please see multi-touch-protocol.txt for details.
149+
150+EV_REL:
151+----------
152+EV_REL events describe relative changes in a property. For example, a mouse may
153+move to the left by a certain number of units, but its absolute position in
154+space is unknown. If the absolute position is known, EV_ABS codes should be used
155+instead of EV_REL codes.
156+
157+A few EV_REL codes have special meanings:
158+
159+* REL_WHEEL, REL_HWHEEL:
160+ - These codes are used for vertical and horizontal scroll wheels,
161+ respectively.
162+
163+EV_ABS:
164+----------
165+EV_ABS events describe absolute changes in a property. For example, a touchpad
166+may emit coordinates for a touch location.
167+
168+A few EV_ABS codes have special meanings:
169+
170+* ABS_DISTANCE:
171+ - Used to describe the distance of a tool from an interaction surface. This
172+ event should only be emitted while the tool is hovering, meaning in close
173+ proximity of the device and while the value of the BTN_TOUCH code is 0. If
174+ the input device may be used freely in three dimensions, consider ABS_Z
175+ instead.
176+
177+* ABS_MT_<name>:
178+ - Used to describe multitouch input events. Please see
179+ multi-touch-protocol.txt for details.
180+
181+EV_SW:
182+----------
183+EV_SW events describe stateful binary switches. For example, the SW_LID code is
184+used to denote when a laptop lid is closed.
185+
186+Upon binding to a device or resuming from suspend, a driver must report
187+the current switch state. This ensures that the device, kernel, and userspace
188+state is in sync.
189+
190+Upon resume, if the switch state is the same as before suspend, then the input
191+subsystem will filter out the duplicate switch state reports. The driver does
192+not need to keep the state of the switch at any time.
193+
194+EV_MSC:
195+----------
196+EV_MSC events are used for input and output events that do not fall under other
197+categories.
198+
199+EV_LED:
200+----------
201+EV_LED events are used for input and output to set and query the state of
202+various LEDs on devices.
203+
204+EV_REP:
205+----------
206+EV_REP events are used for specifying autorepeating events.
207+
208+EV_SND:
209+----------
210+EV_SND events are used for sending sound commands to simple sound output
211+devices.
212+
213+EV_FF:
214+----------
215+EV_FF events are used to initialize a force feedback capable device and to cause
216+such device to feedback.
217+
218+EV_PWR:
219+----------
220+EV_PWR events are a special type of event used specifically for power
221+mangement. Its usage is not well defined. To be addressed later.
222+
223+Guidelines:
224+==========
225+The guidelines below ensure proper single-touch and multi-finger functionality.
226+For multi-touch functionality, see the multi-touch-protocol.txt document for
227+more information.
228+
229+Mice:
230+----------
231+REL_{X,Y} must be reported when the mouse moves. BTN_LEFT must be used to report
232+the primary button press. BTN_{MIDDLE,RIGHT,4,5,etc.} should be used to report
233+further buttons of the device. REL_WHEEL and REL_HWHEEL should be used to report
234+scroll wheel events where available.
235+
236+Touchscreens:
237+----------
238+ABS_{X,Y} must be reported with the location of the touch. BTN_TOUCH must be
239+used to report when a touch is active on the screen.
240+BTN_{MOUSE,LEFT,MIDDLE,RIGHT} must not be reported as the result of touch
241+contact. BTN_TOOL_<name> events should be reported where possible.
242+
243+Trackpads:
244+----------
245+Legacy trackpads that only provide relative position information must report
246+events like mice described above.
247+
248+Trackpads that provide absolute touch position must report ABS_{X,Y} for the
249+location of the touch. BTN_TOUCH should be used to report when a touch is active
250+on the trackpad. Where multi-finger support is available, BTN_TOOL_<name> should
251+be used to report the number of touches active on the trackpad.
252+
253+Tablets:
254+----------
255+BTN_TOOL_<name> events must be reported when a stylus or other tool is active on
256+the tablet. ABS_{X,Y} must be reported with the location of the tool. BTN_TOUCH
257+should be used to report when the tool is in contact with the tablet.
258+BTN_{STYLUS,STYLUS2} should be used to report buttons on the tool itself. Any
259+button may be used for buttons on the tablet except BTN_{MOUSE,LEFT}.
260+BTN_{0,1,2,etc} are good generic codes for unlabeled buttons. Do not use
261+meaningful buttons, like BTN_FORWARD, unless the button is labeled for that
262+purpose on the device.

4−4th April 2009
5−
6−Copyright 2007-2009 Carlos Corbacho <carlos@strangeworlds.co.uk>
7−
8−acer-wmi is a driver to allow you to control various parts of your Acer laptop
9−hardware under Linux which are exposed via ACPI-WMI.
10−
11−This driver completely replaces the old out-of-tree acer_acpi, which I am
12−currently maintaining for bug fixes only on pre-2.6.25 kernels. All development
13−work is now focused solely on acer-wmi.
14−
15−Disclaimer
16−**********
17−
18−Acer and Wistron have provided nothing towards the development acer_acpi or
19−acer-wmi. All information we have has been through the efforts of the developers
20−and the users to discover as much as possible about the hardware.
21−
22−As such, I do warn that this could break your hardware - this is extremely
23−unlikely of course, but please bear this in mind.
24−
25−Background
26−**********
27−
28−acer-wmi is derived from acer_acpi, originally developed by Mark
29−Smith in 2005, then taken over by Carlos Corbacho in 2007, in order to activate
30−the wireless LAN card under a 64-bit version of Linux, as acerhk[1] (the
31−previous solution to the problem) relied on making 32 bit BIOS calls which are
32−not possible in kernel space from a 64 bit OS.

36−Supported Hardware
37−******************
38−
39−NOTE: The Acer Aspire One is not supported hardware. It cannot work with
40−acer-wmi until Acer fix their ACPI-WMI implementation on them, so has been
41−blacklisted until that happens.
42−
43−Please see the website for the current list of known working hardware:
44−
45−http://code.google.com/p/aceracpi/wiki/SupportedHardware
46−
47−If your laptop is not listed, or listed as unknown, and works with acer-wmi,
48−please contact me with a copy of the DSDT.
49−
50−If your Acer laptop doesn't work with acer-wmi, I would also like to see the
51−DSDT.
52−
53−To send me the DSDT, as root/sudo:
54−
55−cat /sys/firmware/acpi/tables/DSDT > dsdt
56−
57−And send me the resulting 'dsdt' file.
58−
59−Usage
60−*****
61−
62−On Acer laptops, acer-wmi should already be autoloaded based on DMI matching.
63−For non-Acer laptops, until WMI based autoloading support is added, you will
64−need to manually load acer-wmi.
65−
66−acer-wmi creates /sys/devices/platform/acer-wmi, and fills it with various
67−files whose usage is detailed below, which enables you to control some of the
68−following (varies between models):
69−
70−* the wireless LAN card radio
71−* inbuilt Bluetooth adapter
72−* inbuilt 3G card
73−* mail LED of your laptop
74−* brightness of the LCD panel
75−
76−Wireless
77−********
78−
79−With regards to wireless, all acer-wmi does is enable the radio on the card. It
80−is not responsible for the wireless LED - once the radio is enabled, this is
81−down to the wireless driver for your card. So the behaviour of the wireless LED,
82−once you enable the radio, will depend on your hardware and driver combination.
83−
84−e.g. With the BCM4318 on the Acer Aspire 5020 series:
85−
86−ndiswrapper: Light blinks on when transmitting
87−b43: Solid light, blinks off when transmitting
88−
89−Wireless radio control is unconditionally enabled - all Acer laptops that support
90−acer-wmi come with built-in wireless. However, should you feel so inclined to
91−ever wish to remove the card, or swap it out at some point, please get in touch
92−with me, as we may well be able to gain some data on wireless card detection.
93−
94−The wireless radio is exposed through rfkill.
95−
96−Bluetooth
97−*********
98−
99−For bluetooth, this is an internal USB dongle, so once enabled, you will get
100−a USB device connection event, and a new USB device appears. When you disable
101−bluetooth, you get the reverse - a USB device disconnect event, followed by the
102−device disappearing again.
103−
104−Bluetooth is autodetected by acer-wmi, so if you do not have a bluetooth module
105−installed in your laptop, this file won't exist (please be aware that it is
106−quite common for Acer not to fit bluetooth to their laptops - so just because
107−you have a bluetooth button on the laptop, doesn't mean that bluetooth is
108−installed).
109−
110−For the adventurously minded - if you want to buy an internal bluetooth
111−module off the internet that is compatible with your laptop and fit it, then
112−it will work just fine with acer-wmi.
113−
114−Bluetooth is exposed through rfkill.
115−
116−3G
117−**
118−
119−3G is currently not autodetected, so the 'threeg' file is always created under
120−sysfs. So far, no-one in possession of an Acer laptop with 3G built-in appears to
121−have tried Linux, or reported back, so we don't have any information on this.
122−
123−If you have an Acer laptop that does have a 3G card in, please contact me so we
124−can properly detect these, and find out a bit more about them.
125−
126−To read the status of the 3G card (0=off, 1=on):
127−cat /sys/devices/platform/acer-wmi/threeg
128−
129−To enable the 3G card:
130−echo 1 > /sys/devices/platform/acer-wmi/threeg
131−
132−To disable the 3G card:
133−echo 0 > /sys/devices/platform/acer-wmi/threeg
134−
135−To set the state of the 3G card when loading acer-wmi, pass:
136−threeg=X (where X is 0 or 1)
137−
138−Mail LED
139−********
140−
141−This can be found in most older Acer laptops supported by acer-wmi, and many
142−newer ones - it is built into the 'mail' button, and blinks when active.
143−
144−On newer (WMID) laptops though, we have no way of detecting the mail LED. If
145−your laptop identifies itself in dmesg as a WMID model, then please try loading
146−acer_acpi with:
147−
148−force_series=2490
149−
150−This will use a known alternative method of reading/ writing the mail LED. If
151−it works, please report back to me with the DMI data from your laptop so this
152−can be added to acer-wmi.
153−
154−The LED is exposed through the LED subsystem, and can be found in:
155−
156−/sys/devices/platform/acer-wmi/leds/acer-wmi::mail/
157−
158−The mail LED is autodetected, so if you don't have one, the LED device won't
159−be registered.
160−
161−Backlight
162−*********
163−
164−The backlight brightness control is available on all acer-wmi supported
165−hardware. The maximum brightness level is usually 15, but on some newer laptops
166−it's 10 (this is again autodetected).

1+The Intel MID PTI project is HW implemented in Intel Atom
2+system-on-a-chip designs based on the Parallel Trace
3+Interface for MIPI P1149.7 cJTAG standard. The kernel solution
4+for this platform involves the following files:

7+./drivers/.../n_tracesink.h
8+./drivers/.../n_tracerouter.c
9+./drivers/.../n_tracesink.c
10+./drivers/.../pti.c
11+
12+pti.c is the driver that enables various debugging features
13+popular on platforms from certain mobile manufacturers.
14+n_tracerouter.c and n_tracesink.c allow extra system information to
15+be collected and routed to the pti driver, such as trace
16+debugging data from a modem. Although n_tracerouter
17+and n_tracesink are a part of the complete PTI solution,
18+these two line disciplines can work separately from
19+pti.c and route any data stream from one /dev/tty node
20+to another /dev/tty node via kernel-space. This provides
21+a stable, reliable connection that will not break unless
22+the user-space application shuts down (plus avoids
23+kernel->user->kernel context switch overheads of routing
24+data).
25+
26+An example debugging usage for this driver system:
27+ *Hook /dev/ttyPTI0 to syslogd. Opening this port will also start
28+ a console device to further capture debugging messages to PTI.
29+ *Hook /dev/ttyPTI1 to modem debugging data to write to PTI HW.
30+ This is where n_tracerouter and n_tracesink are used.
31+ *Hook /dev/pti to a user-level debugging application for writing
32+ to PTI HW.
33+ *Use mipi_* Kernel Driver API in other device drivers for
34+ debugging to PTI by first requesting a PTI write address via
35+ mipi_request_masterchannel(1).
36+
37+Below is example pseudo-code on how a 'privileged' application
38+can hook up n_tracerouter and n_tracesink to any tty on
39+a system. 'Privileged' means the application has enough
40+privileges to successfully manipulate the ldisc drivers
41+but is not just blindly executing as 'root'. Keep in mind
42+the use of ioctl(,TIOCSETD,) is not specific to the n_tracerouter

2+* PTP hardware clock infrastructure for Linux
3+
4+ This patch set introduces support for IEEE 1588 PTP clocks in
5+ Linux. Together with the SO_TIMESTAMPING socket options, this
6+ presents a standardized method for developing PTP user space
7+ programs, synchronizing Linux with external clocks, and using the
8+ ancillary features of PTP hardware clocks.
9+
10+ A new class driver exports a kernel interface for specific clock
11+ drivers and a user space interface. The infrastructure supports a
12+ complete set of PTP hardware clock functionality.
13+
14+ + Basic clock operations
15+ - Set time
16+ - Get time
17+ - Shift the clock by a given offset atomically
18+ - Adjust clock frequency
19+
20+ + Ancillary clock features
21+ - One short or periodic alarms, with signal delivery to user program
22+ - Time stamp external events
23+ - Period output signals configurable from user space
24+ - Synchronization of the Linux system time via the PPS subsystem
25+
26+** PTP hardware clock kernel API
27+
28+ A PTP clock driver registers itself with the class driver. The
29+ class driver handles all of the dealings with user space. The
30+ author of a clock driver need only implement the details of
31+ programming the clock hardware. The clock driver notifies the class
32+ driver of asynchronous events (alarms and external time stamps) via
33+ a simple message passing interface.
34+
35+ The class driver supports multiple PTP clock drivers. In normal use
36+ cases, only one PTP clock is needed. However, for testing and
37+ development, it can be useful to have more than one clock in a
38+ single system, in order to allow performance comparisons.
39+
40+** PTP hardware clock user space API
41+
42+ The class driver also creates a character device for each
43+ registered clock. User space can use an open file descriptor from
44+ the character device as a POSIX clock id and may call
45+ clock_gettime, clock_settime, and clock_adjtime. These calls
46+ implement the basic clock operations.
47+
48+ User space programs may control the clock using standardized
49+ ioctls. A program may query, enable, configure, and disable the
50+ ancillary clock features. User space can receive time stamped
51+ events via blocking read() and poll(). One shot and periodic
52+ signals may be configured via the POSIX timer_settime() system
53+ call.
54+
55+** Writing clock drivers
56+
57+ Clock drivers include include/linux/ptp_clock_kernel.h and register
58+ themselves by presenting a 'struct ptp_clock_info' to the
59+ registration method. Clock drivers must implement all of the
60+ functions in the interface. If a clock does not offer a particular
61+ ancillary feature, then the driver should just return -EOPNOTSUPP
62+ from those functions.
63+
64+ Drivers must ensure that all of the methods in interface are
65+ reentrant. Since most hardware implementations treat the time value
66+ as a 64 bit integer accessed as two 32 bit registers, drivers
67+ should use spin_lock_irqsave/spin_unlock_irqrestore to protect
68+ against concurrent access. This locking cannot be accomplished in
69+ class driver, since the lock may also be needed by the clock
70+ driver's interrupt service routine.
71+
72+** Supported hardware
73+
74+ + Freescale eTSEC gianfar

76+ - 2 Alarm registers (optional interrupt)

80+ - 6 GPIOs programmable as inputs or outputs
81+ - 6 GPIOs with dedicated functions (LED/JTAG/clock) can also be
82+ used as general inputs or outputs
83+ - GPIO inputs can time stamp external triggers

28+In kernel/sched.c, trigger_load_balance() is run periodically on each CPU

66+using it. (Some other Free Software Foundation software is covered by
67+the GNU Lesser General Public License instead.) You can apply it to
68+your programs, too.
69+
70+ When we speak of free software, we are referring to freedom, not
71+price. Our General Public Licenses are designed to make sure that you
72+have the freedom to distribute copies of free software (and charge for
73+this service if you wish), that you receive source code or can get it
74+if you want it, that you can change the software or use pieces of it
75+in new free programs; and that you know you can do these things.
76+
77+ To protect your rights, we need to make restrictions that forbid
78+anyone to deny you these rights or to ask you to surrender the rights.
79+These restrictions translate to certain responsibilities for you if you
80+distribute copies of the software, or if you modify it.
81+
82+ For example, if you distribute copies of such a program, whether
83+gratis or for a fee, you must give the recipients all the rights that
84+you have. You must make sure that they, too, receive or can get the
85+source code. And you must show them these terms so they know their
86+rights.
87+
88+ We protect your rights with two steps: (1) copyright the software, and
89+(2) offer you this license which gives you legal permission to copy,
90+distribute and/or modify the software.
91+
92+ Also, for each author's protection and ours, we want to make certain
93+that everyone understands that there is no warranty for this free
94+software. If the software is modified by someone else and passed on, we
95+want its recipients to know that what they have is not the original, so
96+that any problems introduced by others will not reflect on the original
97+authors' reputations.
98+
99+ Finally, any free program is threatened constantly by software
100+patents. We wish to avoid the danger that redistributors of a free
101+program will individually obtain patent licenses, in effect making the
102+program proprietary. To prevent this, we have made it clear that any
103+patent must be licensed for everyone's free use or not licensed at all.
104+
105+ The precise terms and conditions for copying, distribution and
106+modification follow.
107+
108+ GNU GENERAL PUBLIC LICENSE
109+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
110+
111+ 0. This License applies to any program or other work which contains
112+a notice placed by the copyright holder saying it may be distributed
113+under the terms of this General Public License. The "Program", below,
114+refers to any such program or work, and a "work based on the Program"
115+means either the Program or any derivative work under copyright law:
116+that is to say, a work containing the Program or a portion of it,
117+either verbatim or with modifications and/or translated into another
118+language. (Hereinafter, translation is included without limitation in
119+the term "modification".) Each licensee is addressed as "you".
120+
121+Activities other than copying, distribution and modification are not
122+covered by this License; they are outside its scope. The act of
123+running the Program is not restricted, and the output from the Program
124+is covered only if its contents constitute a work based on the
125+Program (independent of having been made by running the Program).
126+Whether that is true depends on what the Program does.
127+
128+ 1. You may copy and distribute verbatim copies of the Program's
129+source code as you receive it, in any medium, provided that you
130+conspicuously and appropriately publish on each copy an appropriate
131+copyright notice and disclaimer of warranty; keep intact all the
132+notices that refer to this License and to the absence of any warranty;
133+and give any other recipients of the Program a copy of this License
134+along with the Program.
135+
136+You may charge a fee for the physical act of transferring a copy, and
137+you may at your option offer warranty protection in exchange for a fee.
138+
139+ 2. You may modify your copy or copies of the Program or any portion
140+of it, thus forming a work based on the Program, and copy and
141+distribute such modifications or work under the terms of Section 1
142+above, provided that you also meet all of these conditions:
143+
144+ a) You must cause the modified files to carry prominent notices
145+ stating that you changed the files and the date of any change.
146+
147+ b) You must cause any work that you distribute or publish, that in
148+ whole or in part contains or is derived from the Program or any
149+ part thereof, to be licensed as a whole at no charge to all third
150+ parties under the terms of this License.
151+
152+ c) If the modified program normally reads commands interactively
153+ when run, you must cause it, when started running for such
154+ interactive use in the most ordinary way, to print or display an
155+ announcement including an appropriate copyright notice and a
156+ notice that there is no warranty (or else, saying that you provide
157+ a warranty) and that users may redistribute the program under
158+ these conditions, and telling the user how to view a copy of this
159+ License. (Exception: if the Program itself is interactive but
160+ does not normally print such an announcement, your work based on
161+ the Program is not required to print an announcement.)
162+
163+These requirements apply to the modified work as a whole. If
164+identifiable sections of that work are not derived from the Program,
165+and can be reasonably considered independent and separate works in
166+themselves, then this License, and its terms, do not apply to those
167+sections when you distribute them as separate works. But when you
168+distribute the same sections as part of a whole which is a work based
169+on the Program, the distribution of the whole must be on the terms of
170+this License, whose permissions for other licensees extend to the
171+entire whole, and thus to each and every part regardless of who wrote it.
172+
173+Thus, it is not the intent of this section to claim rights or contest
174+your rights to work written entirely by you; rather, the intent is to
175+exercise the right to control the distribution of derivative or
176+collective works based on the Program.
177+
178+In addition, mere aggregation of another work not based on the Program
179+with the Program (or with a work based on the Program) on a volume of
180+a storage or distribution medium does not bring the other work under
181+the scope of this License.
182+
183+ 3. You may copy and distribute the Program (or a work based on it,
184+under Section 2) in object code or executable form under the terms of
185+Sections 1 and 2 above provided that you also do one of the following:
186+
187+ a) Accompany it with the complete corresponding machine-readable
188+ source code, which must be distributed under the terms of Sections
189+ 1 and 2 above on a medium customarily used for software interchange; or,
190+
191+ b) Accompany it with a written offer, valid for at least three
192+ years, to give any third party, for a charge no more than your
193+ cost of physically performing source distribution, a complete
194+ machine-readable copy of the corresponding source code, to be
195+ distributed under the terms of Sections 1 and 2 above on a medium
196+ customarily used for software interchange; or,
197+
198+ c) Accompany it with the information you received as to the offer
199+ to distribute corresponding source code. (This alternative is
200+ allowed only for noncommercial distribution and only if you
201+ received the program in object code or executable form with such
202+ an offer, in accord with Subsection b above.)
203+
204+The source code for a work means the preferred form of the work for
205+making modifications to it. For an executable work, complete source
206+code means all the source code for all modules it contains, plus any
207+associated interface definition files, plus the scripts used to
208+control compilation and installation of the executable. However, as a
209+special exception, the source code distributed need not include
210+anything that is normally distributed (in either source or binary
211+form) with the major components (compiler, kernel, and so on) of the
212+operating system on which the executable runs, unless that component
213+itself accompanies the executable.
214+
215+If distribution of executable or object code is made by offering
216+access to copy from a designated place, then offering equivalent
217+access to copy the source code from the same place counts as
218+distribution of the source code, even though third parties are not
219+compelled to copy the source along with the object code.
220+
221+ 4. You may not copy, modify, sublicense, or distribute the Program
222+except as expressly provided under this License. Any attempt
223+otherwise to copy, modify, sublicense or distribute the Program is
224+void, and will automatically terminate your rights under this License.
225+However, parties who have received copies, or rights, from you under
226+this License will not have their licenses terminated so long as such
227+parties remain in full compliance.
228+
229+ 5. You are not required to accept this License, since you have not
230+signed it. However, nothing else grants you permission to modify or
231+distribute the Program or its derivative works. These actions are
232+prohibited by law if you do not accept this License. Therefore, by
233+modifying or distributing the Program (or any work based on the
234+Program), you indicate your acceptance of this License to do so, and
235+all its terms and conditions for copying, distributing or modifying
236+the Program or works based on it.
237+
238+ 6. Each time you redistribute the Program (or any work based on the
239+Program), the recipient automatically receives a license from the
240+original licensor to copy, distribute or modify the Program subject to
241+these terms and conditions. You may not impose any further
242+restrictions on the recipients' exercise of the rights granted herein.
243+You are not responsible for enforcing compliance by third parties to
244+this License.
245+
246+ 7. If, as a consequence of a court judgment or allegation of patent
247+infringement or for any other reason (not limited to patent issues),
248+conditions are imposed on you (whether by court order, agreement or
249+otherwise) that contradict the conditions of this License, they do not
250+excuse you from the conditions of this License. If you cannot
251+distribute so as to satisfy simultaneously your obligations under this
252+License and any other pertinent obligations, then as a consequence you
253+may not distribute the Program at all. For example, if a patent
254+license would not permit royalty-free redistribution of the Program by
255+all those who receive copies directly or indirectly through you, then
256+the only way you could satisfy both it and this License would be to
257+refrain entirely from distribution of the Program.
258+
259+If any portion of this section is held invalid or unenforceable under
260+any particular circumstance, the balance of the section is intended to
261+apply and the section as a whole is intended to apply in other
262+circumstances.
263+
264+It is not the purpose of this section to induce you to infringe any
265+patents or other property right claims or to contest validity of any
266+such claims; this section has the sole purpose of protecting the
267+integrity of the free software distribution system, which is
268+implemented by public license practices. Many people have made
269+generous contributions to the wide range of software distributed
270+through that system in reliance on consistent application of that
271+system; it is up to the author/donor to decide if he or she is willing
272+to distribute software through any other system and a licensee cannot
273+impose that choice.
274+
275+This section is intended to make thoroughly clear what is believed to
276+be a consequence of the rest of this License.
277+
278+ 8. If the distribution and/or use of the Program is restricted in
279+certain countries either by patents or by copyrighted interfaces, the
280+original copyright holder who places the Program under this License
281+may add an explicit geographical distribution limitation excluding
282+those countries, so that distribution is permitted only in or among
283+countries not thus excluded. In such case, this License incorporates
284+the limitation as if written in the body of this License.
285+
286+ 9. The Free Software Foundation may publish revised and/or new versions
287+of the General Public License from time to time. Such new versions will
288+be similar in spirit to the present version, but may differ in detail to
289+address new problems or concerns.
290+
291+Each version is given a distinguishing version number. If the Program
292+specifies a version number of this License which applies to it and "any
293+later version", you have the option of following the terms and conditions
294+either of that version or of any later version published by the Free
295+Software Foundation. If the Program does not specify a version number of
296+this License, you may choose any version ever published by the Free Software
297+Foundation.
298+
299+ 10. If you wish to incorporate parts of the Program into other free
300+programs whose distribution conditions are different, write to the author
301+to ask for permission. For software which is copyrighted by the Free
302+Software Foundation, write to the Free Software Foundation; we sometimes
303+make exceptions for this. Our decision will be guided by the two goals
304+of preserving the free status of all derivatives of our free software and
305+of promoting the sharing and reuse of software generally.
306+
307+ NO WARRANTY
308+
309+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
310+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
311+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
312+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
313+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
314+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
315+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
316+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
317+REPAIR OR CORRECTION.
318+
319+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
320+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
321+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
322+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
323+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
324+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
325+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
326+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
327+POSSIBILITY OF SUCH DAMAGES.

1+Linux USB Video Class (UVC) driver
2+==================================
3+
4+This file documents some driver-specific aspects of the UVC driver, such as
5+driver-specific ioctls and implementation notes.
6+
7+Questions and remarks can be sent to the Linux UVC development mailing list at
8+linux-uvc-devel@lists.berlios.de.
9+
10+
11+Extension Unit (XU) support
12+---------------------------
13+
14+1. Introduction
15+
16+The UVC specification allows for vendor-specific extensions through extension
17+units (XUs). The Linux UVC driver supports extension unit controls (XU controls)
18+through two separate mechanisms:
19+
20+ - through mappings of XU controls to V4L2 controls
21+ - through a driver-specific ioctl interface
22+
23+The first one allows generic V4L2 applications to use XU controls by mapping
24+certain XU controls onto V4L2 controls, which then show up during ordinary
25+control enumeration.
26+
27+The second mechanism requires uvcvideo-specific knowledge for the application to
28+access XU controls but exposes the entire UVC XU concept to user space for
29+maximum flexibility.
30+
31+Both mechanisms complement each other and are described in more detail below.
32+
33+
34+2. Control mappings
35+
36+The UVC driver provides an API for user space applications to define so-called
37+control mappings at runtime. These allow for individual XU controls or byte
38+ranges thereof to be mapped to new V4L2 controls. Such controls appear and
39+function exactly like normal V4L2 controls (i.e. the stock controls, such as
40+brightness, contrast, etc.). However, reading or writing of such a V4L2 controls
41+triggers a read or write of the associated XU control.
42+
43+The ioctl used to create these control mappings is called UVCIOC_CTRL_MAP.
44+Previous driver versions (before 0.2.0) required another ioctl to be used
45+beforehand (UVCIOC_CTRL_ADD) to pass XU control information to the UVC driver.
46+This is no longer necessary as newer uvcvideo versions query the information
47+directly from the device.
48+
49+For details on the UVCIOC_CTRL_MAP ioctl please refer to the section titled
50+"IOCTL reference" below.
51+
52+
53+3. Driver specific XU control interface
54+
55+For applications that need to access XU controls directly, e.g. for testing
56+purposes, firmware upload, or accessing binary controls, a second mechanism to
57+access XU controls is provided in the form of a driver-specific ioctl, namely
58+UVCIOC_CTRL_QUERY.
59+
60+A call to this ioctl allows applications to send queries to the UVC driver that
61+directly map to the low-level UVC control requests.
62+
63+In order to make such a request the UVC unit ID of the control's extension unit
64+and the control selector need to be known. This information either needs to be
65+hardcoded in the application or queried using other ways such as by parsing the
66+UVC descriptor or, if available, using the media controller API to enumerate a
67+device's entities.
68+
69+Unless the control size is already known it is necessary to first make a
70+UVC_GET_LEN requests in order to be able to allocate a sufficiently large buffer
71+and set the buffer size to the correct value. Similarly, to find out whether
72+UVC_GET_CUR or UVC_SET_CUR are valid requests for a given control, a
73+UVC_GET_INFO request should be made. The bits 0 (GET supported) and 1 (SET
74+supported) of the resulting byte indicate which requests are valid.
75+
76+With the addition of the UVCIOC_CTRL_QUERY ioctl the UVCIOC_CTRL_GET and
77+UVCIOC_CTRL_SET ioctls have become obsolete since their functionality is a
78+subset of the former ioctl. For the time being they are still supported but
79+application developers are encouraged to use UVCIOC_CTRL_QUERY instead.
80+
81+For details on the UVCIOC_CTRL_QUERY ioctl please refer to the section titled
82+"IOCTL reference" below.
83+
84+
85+4. Security
86+
87+The API doesn't currently provide a fine-grained access control facility. The
88+UVCIOC_CTRL_ADD and UVCIOC_CTRL_MAP ioctls require super user permissions.
89+
90+Suggestions on how to improve this are welcome.
91+
92+
93+5. Debugging
94+
95+In order to debug problems related to XU controls or controls in general it is
96+recommended to enable the UVC_TRACE_CONTROL bit in the module parameter 'trace'.
97+This causes extra output to be written into the system log.

102+---- UVCIOC_CTRL_MAP - Map a UVC control to a V4L2 control ----
103+
104+Argument: struct uvc_xu_control_mapping
105+
106+Description:
107+ This ioctl creates a mapping between a UVC control or part of a UVC
108+ control and a V4L2 control. Once mappings are defined, userspace
109+ applications can access vendor-defined UVC control through the V4L2
110+ control API.
111+
112+ To create a mapping, applications fill the uvc_xu_control_mapping
113+ structure with information about an existing UVC control defined with
114+ UVCIOC_CTRL_ADD and a new V4L2 control.
115+
116+ A UVC control can be mapped to several V4L2 controls. For instance,
117+ a UVC pan/tilt control could be mapped to separate pan and tilt V4L2
118+ controls. The UVC control is divided into non overlapping fields using
119+ the 'size' and 'offset' fields and are then independantly mapped to
120+ V4L2 control.
121+
122+ For signed integer V4L2 controls the data_type field should be set to
123+ UVC_CTRL_DATA_TYPE_SIGNED. Other values are currently ignored.
124+
125+Return value:
126+ On success 0 is returned. On error -1 is returned and errno is set
127+ appropriately.

174+
175+Argument: struct uvc_xu_control_query
176+
177+Description:
178+ This ioctl queries a UVC XU control identified by its extension unit ID
179+ and control selector.
180+
181+ There are a number of different queries available that closely
182+ correspond to the low-level control requests described in the UVC
183+ specification. These requests are:
184+
185+ UVC_GET_CUR
186+ Obtain the current value of the control.
187+ UVC_GET_MIN
188+ Obtain the minimum value of the control.
189+ UVC_GET_MAX
190+ Obtain the maximum value of the control.
191+ UVC_GET_DEF
192+ Obtain the default value of the control.
193+ UVC_GET_RES
194+ Query the resolution of the control, i.e. the step size of the
195+ allowed control values.
196+ UVC_GET_LEN
197+ Query the size of the control in bytes.
198+ UVC_GET_INFO
199+ Query the control information bitmap, which indicates whether
200+ get/set requests are supported.
201+ UVC_SET_CUR
202+ Update the value of the control.
203+
204+ Applications must set the 'size' field to the correct length for the
205+ control. Exceptions are the UVC_GET_LEN and UVC_GET_INFO queries, for
206+ which the size must be set to 2 and 1, respectively. The 'data' field
207+ must point to a valid writable buffer big enough to hold the indicated
208+ number of data bytes.
209+
210+ Data is copied directly from the device without any driver-side
211+ processing. Applications are responsible for data buffer formatting,
212+ including little-endian/big-endian conversion. This is particularly
213+ important for the result of the UVC_GET_LEN requests, which is always
214+ returned as a little-endian 16-bit integer by the device.
215+
216+Return value:
217+ On success 0 is returned. On error -1 is returned and errno is set
218+ appropriately.
219+
220+ ENOENT
221+ The device does not support the given control or the specified
222+ extension unit could not be found.
223+ ENOBUFS
224+ The specified buffer size is incorrect (too big or too small).
225+ EINVAL
226+ An invalid request code was passed.

1+MOTIVATION
2+
3+Cleancache is a new optional feature provided by the VFS layer that
4+potentially dramatically increases page cache effectiveness for
5+many workloads in many environments at a negligible cost.
6+
7+Cleancache can be thought of as a page-granularity victim cache for clean
8+pages that the kernel's pageframe replacement algorithm (PFRA) would like
9+to keep around, but can't since there isn't enough memory. So when the
10+PFRA "evicts" a page, it first attempts to use cleancache code to
11+put the data contained in that page into "transcendent memory", memory
12+that is not directly accessible or addressable by the kernel and is
13+of unknown and possibly time-varying size.
14+
15+Later, when a cleancache-enabled filesystem wishes to access a page
16+in a file on disk, it first checks cleancache to see if it already
17+contains it; if it does, the page of data is copied into the kernel
18+and a disk access is avoided.
19+
20+Transcendent memory "drivers" for cleancache are currently implemented
21+in Xen (using hypervisor memory) and zcache (using in-kernel compressed
22+memory) and other implementations are in development.
23+
24+FAQs are included below.
25+
26+IMPLEMENTATION OVERVIEW
27+
28+A cleancache "backend" that provides transcendent memory registers itself
29+to the kernel's cleancache "frontend" by calling cleancache_register_ops,
30+passing a pointer to a cleancache_ops structure with funcs set appropriately.
31+Note that cleancache_register_ops returns the previous settings so that
32+chaining can be performed if desired. The functions provided must conform to
33+certain semantics as follows:
34+
35+Most important, cleancache is "ephemeral". Pages which are copied into
36+cleancache have an indefinite lifetime which is completely unknowable
37+by the kernel and so may or may not still be in cleancache at any later time.
38+Thus, as its name implies, cleancache is not suitable for dirty pages.
39+Cleancache has complete discretion over what pages to preserve and what
40+pages to discard and when.
41+
42+Mounting a cleancache-enabled filesystem should call "init_fs" to obtain a
43+pool id which, if positive, must be saved in the filesystem's superblock;
44+a negative return value indicates failure. A "put_page" will copy a
45+(presumably about-to-be-evicted) page into cleancache and associate it with
46+the pool id, a file key, and a page index into the file. (The combination
47+of a pool id, a file key, and an index is sometimes called a "handle".)
48+A "get_page" will copy the page, if found, from cleancache into kernel memory.
49+A "flush_page" will ensure the page no longer is present in cleancache;
50+a "flush_inode" will flush all pages associated with the specified file;
51+and, when a filesystem is unmounted, a "flush_fs" will flush all pages in
52+all files specified by the given pool id and also surrender the pool id.
53+
54+An "init_shared_fs", like init_fs, obtains a pool id but tells cleancache
55+to treat the pool as shared using a 128-bit UUID as a key. On systems
56+that may run multiple kernels (such as hard partitioned or virtualized
57+systems) that may share a clustered filesystem, and where cleancache
58+may be shared among those kernels, calls to init_shared_fs that specify the
59+same UUID will receive the same pool id, thus allowing the pages to
60+be shared. Note that any security requirements must be imposed outside
61+of the kernel (e.g. by "tools" that control cleancache). Or a
62+cleancache implementation can simply disable shared_init by always
63+returning a negative value.
64+
65+If a get_page is successful on a non-shared pool, the page is flushed (thus
66+making cleancache an "exclusive" cache). On a shared pool, the page
67+is NOT flushed on a successful get_page so that it remains accessible to
68+other sharers. The kernel is responsible for ensuring coherency between
69+cleancache (shared or not), the page cache, and the filesystem, using
70+cleancache flush operations as required.
71+
72+Note that cleancache must enforce put-put-get coherency and get-get
73+coherency. For the former, if two puts are made to the same handle but
74+with different data, say AAA by the first put and BBB by the second, a
75+subsequent get can never return the stale data (AAA). For get-get coherency,
76+if a get for a given handle fails, subsequent gets for that handle will
77+never succeed unless preceded by a successful put with that handle.
78+
79+Last, cleancache provides no SMP serialization guarantees; if two
80+different Linux threads are simultaneously putting and flushing a page
81+with the same handle, the results are indeterminate. Callers must
82+lock the page to ensure serial behavior.
83+
84+CLEANCACHE PERFORMANCE METRICS
85+
86+Cleancache monitoring is done by sysfs files in the
87+/sys/kernel/mm/cleancache directory. The effectiveness of cleancache
88+can be measured (across all filesystems) with:
89+
90+succ_gets - number of gets that were successful
91+failed_gets - number of gets that failed
92+puts - number of puts attempted (all "succeed")
93+flushes - number of flushes attempted
94+
95+A backend implementatation may provide additional metrics.
96+
97+FAQ
98+
99+1) Where's the value? (Andrew Morton)
100+
101+Cleancache provides a significant performance benefit to many workloads
102+in many environments with negligible overhead by improving the
103+effectiveness of the pagecache. Clean pagecache pages are
104+saved in transcendent memory (RAM that is otherwise not directly
105+addressable to the kernel); fetching those pages later avoids "refaults"
106+and thus disk reads.
107+
108+Cleancache (and its sister code "frontswap") provide interfaces for
109+this transcendent memory (aka "tmem"), which conceptually lies between
110+fast kernel-directly-addressable RAM and slower DMA/asynchronous devices.
111+Disallowing direct kernel or userland reads/writes to tmem
112+is ideal when data is transformed to a different form and size (such
113+as with compression) or secretly moved (as might be useful for write-
114+balancing for some RAM-like devices). Evicted page-cache pages (and
115+swap pages) are a great use for this kind of slower-than-RAM-but-much-
116+faster-than-disk transcendent memory, and the cleancache (and frontswap)
117+"page-object-oriented" specification provides a nice way to read and
118+write -- and indirectly "name" -- the pages.
119+
120+In the virtual case, the whole point of virtualization is to statistically
121+multiplex physical resources across the varying demands of multiple
122+virtual machines. This is really hard to do with RAM and efforts to
123+do it well with no kernel change have essentially failed (except in some
124+well-publicized special-case workloads). Cleancache -- and frontswap --
125+with a fairly small impact on the kernel, provide a huge amount
126+of flexibility for more dynamic, flexible RAM multiplexing.
127+Specifically, the Xen Transcendent Memory backend allows otherwise
128+"fallow" hypervisor-owned RAM to not only be "time-shared" between multiple
129+virtual machines, but the pages can be compressed and deduplicated to
130+optimize RAM utilization. And when guest OS's are induced to surrender
131+underutilized RAM (e.g. with "self-ballooning"), page cache pages
132+are the first to go, and cleancache allows those pages to be
133+saved and reclaimed if overall host system memory conditions allow.
134+
135+And the identical interface used for cleancache can be used in
136+physical systems as well. The zcache driver acts as a memory-hungry
137+device that stores pages of data in a compressed state. And
138+the proposed "RAMster" driver shares RAM across multiple physical
139+systems.
140+
141+2) Why does cleancache have its sticky fingers so deep inside the
142+ filesystems and VFS? (Andrew Morton and Christoph Hellwig)
143+
144+The core hooks for cleancache in VFS are in most cases a single line
145+and the minimum set are placed precisely where needed to maintain
146+coherency (via cleancache_flush operations) between cleancache,
147+the page cache, and disk. All hooks compile into nothingness if
148+cleancache is config'ed off and turn into a function-pointer-
149+compare-to-NULL if config'ed on but no backend claims the ops
150+functions, or to a compare-struct-element-to-negative if a
151+backend claims the ops functions but a filesystem doesn't enable
152+cleancache.
153+
154+Some filesystems are built entirely on top of VFS and the hooks
155+in VFS are sufficient, so don't require an "init_fs" hook; the
156+initial implementation of cleancache didn't provide this hook.
157+But for some filesystems (such as btrfs), the VFS hooks are
158+incomplete and one or more hooks in fs-specific code are required.
159+And for some other filesystems, such as tmpfs, cleancache may
160+be counterproductive. So it seemed prudent to require a filesystem
161+to "opt in" to use cleancache, which requires adding a hook in
162+each filesystem. Not all filesystems are supported by cleancache
163+only because they haven't been tested. The existing set should
164+be sufficient to validate the concept, the opt-in approach means
165+that untested filesystems are not affected, and the hooks in the
166+existing filesystems should make it very easy to add more
167+filesystems in the future.
168+
169+The total impact of the hooks to existing fs and mm files is only
170+about 40 lines added (not counting comments and blank lines).
171+
172+3) Why not make cleancache asynchronous and batched so it can
173+ more easily interface with real devices with DMA instead
174+ of copying each individual page? (Minchan Kim)
175+
176+The one-page-at-a-time copy semantics simplifies the implementation
177+on both the frontend and backend and also allows the backend to
178+do fancy things on-the-fly like page compression and
179+page deduplication. And since the data is "gone" (copied into/out
180+of the pageframe) before the cleancache get/put call returns,
181+a great deal of race conditions and potential coherency issues
182+are avoided. While the interface seems odd for a "real device"
183+or for real kernel-addressable RAM, it makes perfect sense for
184+transcendent memory.
185+
186+4) Why is non-shared cleancache "exclusive"? And where is the
187+ page "flushed" after a "get"? (Minchan Kim)
188+
189+The main reason is to free up space in transcendent memory and
190+to avoid unnecessary cleancache_flush calls. If you want inclusive,
191+the page can be "put" immediately following the "get". If
192+put-after-get for inclusive becomes common, the interface could
193+be easily extended to add a "get_no_flush" call.
194+
195+The flush is done by the cleancache backend implementation.
196+
197+5) What's the performance impact?
198+
199+Performance analysis has been presented at OLS'09 and LCA'10.
200+Briefly, performance gains can be significant on most workloads,
201+especially when memory pressure is high (e.g. when RAM is
202+overcommitted in a virtual workload); and because the hooks are
203+invoked primarily in place of or in addition to a disk read/write,
204+overhead is negligible even in worst case workloads. Basically
205+cleancache replaces I/O with memory-copy-CPU-overhead; on older
206+single-core systems with slow memory-copy speeds, cleancache
207+has little value, but in newer multicore machines, especially
208+consolidated/virtualized machines, it has great value.
209+
210+6) How do I add cleancache support for filesystem X? (Boaz Harrash)
211+
212+Filesystems that are well-behaved and conform to certain
213+restrictions can utilize cleancache simply by making a call to
214+cleancache_init_fs at mount time. Unusual, misbehaving, or
215+poorly layered filesystems must either add additional hooks
216+and/or undergo extensive additional testing... or should just
217+not enable the optional cleancache.
218+
219+Some points for a filesystem to consider:
220+
221+- The FS should be block-device-based (e.g. a ram-based FS such
222+ as tmpfs should not enable cleancache)
223+- To ensure coherency/correctness, the FS must ensure that all
224+ file removal or truncation operations either go through VFS or
225+ add hooks to do the equivalent cleancache "flush" operations
226+- To ensure coherency/correctness, either inode numbers must
227+ be unique across the lifetime of the on-disk file OR the
228+ FS must provide an "encode_fh" function.
229+- The FS must call the VFS superblock alloc and deactivate routines
230+ or add hooks to do the equivalent cleancache calls done there.
231+- To maximize performance, all pages fetched from the FS should
232+ go through the do_mpag_readpage routine or the FS should add
233+ hooks to do the equivalent (cf. btrfs)
234+- Currently, the FS blocksize must be the same as PAGESIZE. This
235+ is not an architectural restriction, but no backends currently
236+ support anything different.
237+- A clustered FS should invoke the "shared_init_fs" cleancache
238+ hook to get best performance for some backends.
239+
240+7) Why not use the KVA of the inode as the key? (Christoph Hellwig)
241+
242+If cleancache would use the inode virtual address instead of
243+inode/filehandle, the pool id could be eliminated. But, this
244+won't work because cleancache retains pagecache data pages
245+persistently even when the inode has been pruned from the
246+inode unused list, and only flushes the data page if the file
247+gets removed/truncated. So if cleancache used the inode kva,
248+there would be potential coherency issues if/when the inode
249+kva is reused for a different file. Alternately, if cleancache
250+flushed the pages when the inode kva was freed, much of the value
251+of cleancache would be lost because the cache of pages in cleanache
252+is potentially much larger than the kernel pagecache and is most
253+useful if the pages survive inode cache removal.
254+
255+8) Why is a global variable required?
256+
257+The cleancache_enabled flag is checked in all of the frequently-used
258+cleancache hooks. The alternative is a function call to check a static
259+variable. Since cleancache is enabled dynamically at runtime, systems
260+that don't enable cleancache would suffer thousands (possibly
261+tens-of-thousands) of unnecessary function calls per second. So the
262+global variable allows cleancache to be enabled by default at compile
263+time, but have insignificant performance impact when cleancache remains
264+disabled at runtime.
265+
266+9) Does cleanache work with KVM?
267+
268+The memory model of KVM is sufficiently different that a cleancache
269+backend may have less value for KVM. This remains to be tested,
270+especially in an overcommitted system.
271+
272+10) Does cleancache work in userspace? It sounds useful for
273+ memory hungry caches like web browsers. (Jamie Lokier)
274+
275+No plans yet, though we agree it sounds useful, at least for
276+apps that bypass the page cache (e.g. O_DIRECT).

379380 * Unless work items are expected to consume a huge amount of CPU
380381 cycles, using a bound wq is usually beneficial due to the increased
381382 level of locality in wq operations and work item execution.
383+
384+
385+7. Debugging
386+
387+Because the work functions are executed by generic worker threads
388+there are a few tricks needed to shed some light on misbehaving
389+workqueue users.
390+
391+Worker threads show up in the process list as:
392+
393+root 5671 0.0 0.0 0 0 ? S 12:07 0:00 [kworker/0:1]
394+root 5672 0.0 0.0 0 0 ? S 12:07 0:00 [kworker/1:2]
395+root 5673 0.0 0.0 0 0 ? S 12:12 0:00 [kworker/0:0]
396+root 5674 0.0 0.0 0 0 ? S 12:13 0:00 [kworker/1:0]
397+
398+If kworkers are going crazy (using too much cpu), there are two types
399+of possible problems:
400+
401+ 1. Something beeing scheduled in rapid succession
402+ 2. A single work item that consumes lots of cpu cycles
403+
404+The first one can be tracked using tracing:
405+
406+ $ echo workqueue:workqueue_queue_work > /sys/kernel/debug/tracing/set_event
407+ $ cat /sys/kernel/debug/tracing/trace_pipe > out.txt
408+ (wait a few secs)
409+ ^C
410+
411+If something is busy looping on work queueing, it would be dominating
412+the output and the offender can be determined with the work item
413+function.
414+
415+For the second type of problems it should be possible to just check
416+the stack trace of the offending worker thread.
417+
418+ $ cat /proc/THE_OFFENDING_KWORKER/stack
419+
420+The work item's function should be trivially visible in the stack
421+trace.
