7 profile that's active when the mouse is powered on next time.
8 When written, this file sets the number of the startup profile
9 and the mouse activates this profile immediately.

175 parameter indicates the size of the internal allocation
176 unit in bytes if reported by the device. Otherwise the

184Description:
185 Devices that support discard functionality may have
186 internal limits on the number of bytes that can be
187 trimmed or unmapped in a single operation. Some storage
188 protocols also have inherent limits on the number of
189 blocks that can be described in a single command. The
190 discard_max_bytes parameter is set by the device driver
191 to the maximum number of bytes that can be discarded in
192 a single operation. Discard requests issued to the
193 device must not exceed this limit. A discard_max_bytes
194 value of 0 means that the device does not support
195 discard functionality.

201 Devices that support discard functionality may return
202 stale or random data when a previously discarded block
203 is read back. This can cause problems if the filesystem
204 expects discarded blocks to be explicitly cleared. If a
205 device reports that it deterministically returns zeroes
206 when a discarded area is read the discard_zeroes_data
207 parameter will be set to one. Otherwise it will be 0 and
208 the result of reading a discarded area is undefined.

4Description:
5 Some servers used internally at Google have firmware
6 that provides callback functionality via explicit SMI
7 triggers. Some of the callbacks are similar to those
8 provided by the EFI runtime services page, but due to
9 historical reasons this different entry-point has been
10 used.
11
12 The gsmi driver implements the kernel's abstraction for
13 these firmware callbacks. Currently, this functionality
14 is limited to handling the system event log and getting
15 access to EFI-style variables stored in nvram.

53 clearing though, and this writes to this file
54 will error out if the firmware doesn't like your
55 submitted fraction.

435 "N" This indicates that some of the blocked tasks are preventing
436 the current normal (non-expedited) grace period from

440 the current expedited grace period from completing.

462

464
465o "ntb" is the number of tasks boosted.
466
467o "neb" is the number of tasks boosted in order to complete an
468 expedited grace period.
469
470o "nnb" is the number of tasks boosted in order to complete a
471 normal (non-expedited) grace period. When boosting a task
472 that was blocking both an expedited and a normal grace period,
473 it is counted against the expedited total above.
474
475o "j" is the low-order 16 bits of the jiffies counter in
476 hexadecimal.
477
478o "bt" is the low-order 16 bits of the value that the jiffies
479 counter will have when we next start boosting, assuming that
480 the current grace period does not end beforehand. This is
481 also in hexadecimal.
482
483o "balk: nt" counts the number of times we didn't boost (in
484 other words, we balked) even though it was time to boost because
485 there were no blocked tasks to boost. This situation occurs
486 when there is one blocked task on one rcu_node structure and
487 none on some other rcu_node structure.
488
489o "egt" counts the number of times we balked because although
490 there were blocked tasks, none of them were blocking the
491 current grace period, whether expedited or otherwise.

493o "bt" counts the number of times we balked because boosting
494 had already been initiated for the current grace period.
495
496o "nb" counts the number of times we balked because there
497 was at least one task blocking the current non-expedited grace
498 period that never had blocked. If it is already running, it
499 just won't help to boost its priority!
500

172There is a cciss_tape_cmds module parameter which can be used to make cciss
173allocate more commands for use by tape drives. Ordinarily only a few commands
174(6) are allocated for tape drives because tape drives are slow and
175infrequently used and the primary purpose of Smart Array controllers is to
176act as a RAID controller for disk drives, so the vast majority of commands
177are allocated for disk devices. However, if you have more than a few tape
178drives attached to a smart array, the default number of commands may not be
179enought (for example, if you have 8 tape drives, you could only rewind 6
180at one time with the default number of commands.) The cciss_tape_cmds module

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

10CPI 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

38 Valid values are "oscillator" and "platform"
39 "oscillator": CAN engine clock source is oscillator clock.
40 "platform" The CAN engine clock source is the bus clock
41 (platform clock).

79
80General 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
87Clock 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.

155 There is one single entry point to the kernel, at the start
156 of the kernel image. That entry point supports two calling

182 (defined in chapter II) in RAM. Device tree can be located
183 anywhere in system RAM, but it should be aligned on a 64 bit
184 boundary.
185
186 The kernel will differentiate between ATAGS and device tree booting by
187 reading the memory pointed to by r2 and looking for either the flattened
188 device tree block magic value (0xd00dfeed) or the ATAG_CORE value at
189 offset 0x4 from r2 (0x54410001).

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

35Fields
36~~~~~~
37g_list: Node in the global device list.
38
39node: Node in device's parent's children list.
40
41bus_list: Node in device's bus's devices list.
42
43driver_list: Node in device's driver's devices list.
44
45intf_list: List of intf_data. There is one structure allocated for
46 each interface that the device supports.
47
48children: List of child devices.
49
50parent: *** FIXME ***
51
52name: ASCII description of device.
53 Example: " 3Com Corporation 3c905 100BaseTX [Boomerang]"
54
55bus_id: ASCII representation of device's bus position. This
56 field should be a name unique across all devices on the
57 bus type the device belongs to.
58
59 Example: PCI bus_ids are in the form of
60 <bus number>:<slot number>.<function number>
61 This name is unique across all PCI devices in the system.
62
63lock: Spinlock for the device.
64
65refcount: Reference count on the device.
66
67bus: Pointer to struct bus_type that device belongs to.
68
69dir: Device's sysfs directory.
70
71class_num: Class-enumerated value of the device.
72
73driver: Pointer to struct device_driver that controls the device.
74
75driver_data: Driver-specific data.
76
77platform_data: Platform data specific to the device.
78
79 Example: for devices on custom boards, as typical of embedded
80 and SOC based hardware, Linux often uses platform_data to point
81 to board-specific structures describing devices and how they
82 are wired. That can include what ports are available, chip
83 variants, which GPIO pins act in what additional roles, and so
84 on. This shrinks the "Board Support Packages" (BSPs) and
85 minimizes board-specific #ifdefs in drivers.
86
87current_state: Current power state of the device.
88
89saved_state: Pointer to saved state of the device. This is usable by
90 the device driver controlling the device.
91
92release: Callback to free the device after all references have
93 gone away. This should be set by the allocator of the
94 device (i.e. the bus driver that discovered the device).

133Our current recommendation is to use Inferno (http://www.vitanuova.com/nferno/index.html)135Protocol specifications are maintained on github:
134as the 9p server. You can start a 9p server under Inferno by issuing the136http://ericvh.github.com/9p-rfc/
135following command:
136 ; styxlisten -A tcp!*!564 export '#U*'
137 137
138The -A specifies an unauthenticated export. The 564 is the port # (you may1389p client and server implementations are listed on
139have to choose a higher port number if running as a normal user). The '#U*'139http://9p.cat-v.org/implementations
140specifies exporting the root of the Linux name space. You may specify a

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

16From the datasheet:
17
18"The EMC6W201 is an environmental monitoring device with automatic fan
19control capability and enhanced system acoustics for noise suppression.
20This ACPI compliant device provides hardware monitoring for up to six
21voltages (including its own VCC) and five external thermal sensors,
22measures the speed of up to five fans, and controls the speed of
23multiple DC fans using three Pulse Width Modulator (PWM) outputs. Note
24that it is possible to control more than three fans by connecting two
25fans to one PWM output. The EMC6W201 will be available in a 36-pin
26QFN package."
27
28The device is functionally close to the EMC6D100 series, but is
29register-incompatible.
30
31The driver currently only supports the monitoring of the voltages,
32temperatures and fan speeds. Limits can be changed. Alarms are not
33supported, and neither is fan speed control.

18This driver permits reading of registers providing power information
19of AMD Family 15h processors.
20
21For AMD Family 15h processors the following power values can be
22calculated using different processor northbridge function registers:
23
24* BasePwrWatts: Specifies in watts the maximum amount of power
25 consumed by the processor for NB and logic external to the core.
26* ProcessorPwrWatts: Specifies in watts the maximum amount of power
27 the processor can support.
28* CurrPwrWatts: Specifies in watts the current amount of power being
29 consumed by the processor.
30
31This driver provides ProcessorPwrWatts and CurrPwrWatts:
32* power1_crit (ProcessorPwrWatts)
33* power1_input (CurrPwrWatts)
34
35On multi-node processors the calculated value is for the entire
36package and not for a single node. Thus the driver creates sysfs
37attributes only for internal node0 of a multi-node processor.

14-----------
15
16This driver permits reading package level temperature sensor embedded inside
17Intel CPU package. The sensors can be in core, uncore, memory controller, or
18other components in a package. The feature is first implemented in Intel Sandy
19Bridge platform.
20
21Temperature is measured in degrees Celsius and measurement resolution is
221 degree C. Valid temperatures are from 0 to TjMax degrees C, because the actual
23value of temperature register is in fact a delta from TjMax.
24
25Temperature known as TjMax is the maximum junction temperature of package.
26We get this from MSR_IA32_TEMPERATURE_TARGET. If the MSR is not accessible,
27we define TjMax as 100 degrees Celsius. At this temperature, protection
28mechanism will perform actions to forcibly cool down the package. Alarm
29may be raised, if the temperature grows enough (more than TjMax) to trigger
30the Out-Of-Spec bit. Following table summarizes the exported sysfs files:
31
32temp1_input - Package temperature (in millidegrees Celsius).
33temp1_max - All cooling devices should be turned on.
34temp1_crit - Maximum junction temperature (in millidegrees Celsius).
35temp1_crit_alarm - Set when Out-of-spec bit is set, never clears.
36 Correct CPU operation is no longer guaranteed.

29Description
30-----------
31
32The SHT10, SHT11, SHT15, SHT71, and SHT75 are humidity and temperature
33sensors.
34
35The devices communicate using two GPIO lines.
36
37Supported resolutions for the measurements are 14 bits for temperature and 12
38bits for humidity, or 12 bits for temperature and 8 bits for humidity.
39
40The humidity calibration coefficients are programmed into an OTP memory on the
41chip. These coefficients are used to internally calibrate the signals from the
42sensors. Disabling the reload of those coefficients allows saving 10ms for each
43measurement and decrease power consumption, while loosing on precision.
44
45Some options may be set directly in the sht15_platform_data structure
46or via sysfs attributes.
47
48Notes:
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.

1 How to Get Your Patch Accepted Into the Hwmon Subsystem
2 -------------------------------------------------------
3
4This text is is a collection of suggestions for people writing patches or
5drivers for the hwmon subsystem. Following these suggestions will greatly
6increase the chances of your change being accepted.
7
8
91. 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
342. 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
493. 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.

1274 bytes/firmware 1. The versions < 02.08.00, with the exception of 02.00.30, as

1The input protocol uses a map of types and codes to express input device values
2to userspace. This document describes the types and codes and how and when they
3may be used.
4
5A single hardware event generates multiple input events. Each input event
6contains the new value of a single data item. A special event type, EV_SYN, is
7used to separate input events into packets of input data changes occurring at
8the same moment in time. In the following, the term "event" refers to a single
9input event encompassing a type, code, and value.
10
11The input protocol is a stateful protocol. Events are emitted only when values
12of event codes have changed. However, the state is maintained within the Linux
13input subsystem; drivers do not need to maintain the state and may attempt to
14emit unchanged values without harm. Userspace may obtain the current state of
15event code values using the EVIOCG* ioctls defined in linux/input.h. The event
16reports supported by a device are also provided by sysfs in
17class/input/event*/device/capabilities/, and the properties of a device are
18provided in class/input/event*/device/properties.
19
20Types:
21==========
22Types are groupings of codes under a logical input construct. Each type has a
23set of applicable codes to be used in generating events. See the Codes section
24for 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
66Codes:
67==========
68Codes define the precise type of event.
69
70EV_SYN:
71----------
72EV_SYN event values are undefined. Their usage is defined only by when they are
73sent 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
94EV_KEY:
95----------
96EV_KEY events take the form KEY_<name> or BTN_<name>. For example, KEY_A is used
97to represent the 'A' key on a keyboard. When a key is depressed, an event with
98the key's code is emitted with value 1. When the key is released, an event is
99emitted with value 0. Some hardware send events when a key is repeated. These
100events have a value of 2. In general, KEY_<name> is used for keyboard keys, and
101BTN_<name> is used for other types of momentary switch events.
102
103A 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
124Note: For appropriate function of the legacy mousedev emulation driver,
125BTN_TOUCH must be the first evdev code emitted in a synchronization frame.
126
127Note: Historically a touch device with BTN_TOOL_FINGER and BTN_TOUCH was
128interpreted as a touchpad by userspace, while a similar device without
129BTN_TOOL_FINGER was interpreted as a touchscreen. For backwards compatibility
130with current userspace it is recommended to follow this distinction. In the
131future, this distinction will be deprecated and the device properties ioctl
132EVIOCGPROP, 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
144Note: Historically some drivers emitted multiple of the finger count codes with
145a value of 1 in the same synchronization frame. This usage is deprecated.
146
147Note: In multitouch drivers, the input_mt_report_finger_count() function should
148be used to emit these codes. Please see multi-touch-protocol.txt for details.
149
150EV_REL:
151----------
152EV_REL events describe relative changes in a property. For example, a mouse may
153move to the left by a certain number of units, but its absolute position in
154space is unknown. If the absolute position is known, EV_ABS codes should be used
155instead of EV_REL codes.
156
157A 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
163EV_ABS:
164----------
165EV_ABS events describe absolute changes in a property. For example, a touchpad
166may emit coordinates for a touch location.
167
168A 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
181EV_SW:
182----------
183EV_SW events describe stateful binary switches. For example, the SW_LID code is
184used to denote when a laptop lid is closed.
185
186Upon binding to a device or resuming from suspend, a driver must report
187the current switch state. This ensures that the device, kernel, and userspace
188state is in sync.
189
190Upon resume, if the switch state is the same as before suspend, then the input
191subsystem will filter out the duplicate switch state reports. The driver does
192not need to keep the state of the switch at any time.
193
194EV_MSC:
195----------
196EV_MSC events are used for input and output events that do not fall under other
197categories.
198
199EV_LED:
200----------
201EV_LED events are used for input and output to set and query the state of
202various LEDs on devices.
203
204EV_REP:
205----------
206EV_REP events are used for specifying autorepeating events.
207
208EV_SND:
209----------
210EV_SND events are used for sending sound commands to simple sound output
211devices.
212
213EV_FF:
214----------
215EV_FF events are used to initialize a force feedback capable device and to cause
216such device to feedback.
217
218EV_PWR:
219----------
220EV_PWR events are a special type of event used specifically for power
221mangement. Its usage is not well defined. To be addressed later.
222
223Guidelines:
224==========
225The guidelines below ensure proper single-touch and multi-finger functionality.
226For multi-touch functionality, see the multi-touch-protocol.txt document for
227more information.
228
229Mice:
230----------
231REL_{X,Y} must be reported when the mouse moves. BTN_LEFT must be used to report
232the primary button press. BTN_{MIDDLE,RIGHT,4,5,etc.} should be used to report
233further buttons of the device. REL_WHEEL and REL_HWHEEL should be used to report
234scroll wheel events where available.
235
236Touchscreens:
237----------
238ABS_{X,Y} must be reported with the location of the touch. BTN_TOUCH must be
239used to report when a touch is active on the screen.
240BTN_{MOUSE,LEFT,MIDDLE,RIGHT} must not be reported as the result of touch
241contact. BTN_TOOL_<name> events should be reported where possible.
242
243Trackpads:
244----------
245Legacy trackpads that only provide relative position information must report
246events like mice described above.
247
248Trackpads that provide absolute touch position must report ABS_{X,Y} for the
249location of the touch. BTN_TOUCH should be used to report when a touch is active
250on the trackpad. Where multi-finger support is available, BTN_TOOL_<name> should
251be used to report the number of touches active on the trackpad.
252
253Tablets:
254----------
255BTN_TOOL_<name> events must be reported when a stylus or other tool is active on
256the tablet. ABS_{X,Y} must be reported with the location of the tool. BTN_TOUCH
257should be used to report when the tool is in contact with the tablet.
258BTN_{STYLUS,STYLUS2} should be used to report buttons on the tool itself. Any
259button may be used for buttons on the tablet except BTN_{MOUSE,LEFT}.
260BTN_{0,1,2,etc} are good generic codes for unlabeled buttons. Do not use
261meaningful buttons, like BTN_FORWARD, unless the button is labeled for that
262purpose on the device.

340Andrew は個別のサブシステムカーネルツリーとパッチを全て集めてきて
341linux-kernel メーリングリストで収集された多数のパッチと同時に一つにま
342とめます。
343このツリーは新機能とパッチが検証される場となります。ある期間の間パッチ
344が -mm に入って価値を証明されたら、Andrew やサブシステムメンテナが、
345メインラインへ入れるように Linus にプッシュします。

348チが -mm ツリーでテストされることが強く推奨されています。マージウィン

356どうぞこれらのカーネルリリースをテストに使ってみて、そしてもし問題があ
357れば、またもし全てが正しく動作したとしても、linux-kernel メーリングリ

1Acer Laptop WMI Extras Driver

3Version 0.3
44th April 2009
5
6Copyright 2007-2009 Carlos Corbacho <carlos@strangeworlds.co.uk>
7
8acer-wmi is a driver to allow you to control various parts of your Acer laptop
9hardware under Linux which are exposed via ACPI-WMI.
10
11This driver completely replaces the old out-of-tree acer_acpi, which I am
12currently maintaining for bug fixes only on pre-2.6.25 kernels. All development
13work is now focused solely on acer-wmi.
14
15Disclaimer
16**********
17
18Acer and Wistron have provided nothing towards the development acer_acpi or
19acer-wmi. All information we have has been through the efforts of the developers
20and the users to discover as much as possible about the hardware.
21
22As such, I do warn that this could break your hardware - this is extremely
23unlikely of course, but please bear this in mind.
24
25Background
26**********
27
28acer-wmi is derived from acer_acpi, originally developed by Mark
29Smith in 2005, then taken over by Carlos Corbacho in 2007, in order to activate
30the wireless LAN card under a 64-bit version of Linux, as acerhk[1] (the
31previous solution to the problem) relied on making 32 bit BIOS calls which are
32not possible in kernel space from a 64 bit OS.
33
34[1] acerhk: http://www.cakey.de/acerhk/
35
36Supported Hardware
37******************
38
39NOTE: The Acer Aspire One is not supported hardware. It cannot work with
40acer-wmi until Acer fix their ACPI-WMI implementation on them, so has been
41blacklisted until that happens.
42
43Please see the website for the current list of known working hardware:
44
45http://code.google.com/p/aceracpi/wiki/SupportedHardware
46
47If your laptop is not listed, or listed as unknown, and works with acer-wmi,
48please contact me with a copy of the DSDT.
49
50If your Acer laptop doesn't work with acer-wmi, I would also like to see the
51DSDT.
52
53To send me the DSDT, as root/sudo:
54
55cat /sys/firmware/acpi/tables/DSDT > dsdt
56
57And send me the resulting 'dsdt' file.
58
59Usage
60*****
61
62On Acer laptops, acer-wmi should already be autoloaded based on DMI matching.
63For non-Acer laptops, until WMI based autoloading support is added, you will
64need to manually load acer-wmi.
65
66acer-wmi creates /sys/devices/platform/acer-wmi, and fills it with various
67files whose usage is detailed below, which enables you to control some of the
68following (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
76Wireless
77********
78
79With regards to wireless, all acer-wmi does is enable the radio on the card. It
80is not responsible for the wireless LED - once the radio is enabled, this is
81down to the wireless driver for your card. So the behaviour of the wireless LED,
82once you enable the radio, will depend on your hardware and driver combination.
83
84e.g. With the BCM4318 on the Acer Aspire 5020 series:
85
86ndiswrapper: Light blinks on when transmitting
87b43: Solid light, blinks off when transmitting
88
89Wireless radio control is unconditionally enabled - all Acer laptops that support
90acer-wmi come with built-in wireless. However, should you feel so inclined to
91ever wish to remove the card, or swap it out at some point, please get in touch
92with me, as we may well be able to gain some data on wireless card detection.
93
94The wireless radio is exposed through rfkill.
95
96Bluetooth
97*********
98
99For bluetooth, this is an internal USB dongle, so once enabled, you will get
100a USB device connection event, and a new USB device appears. When you disable
101bluetooth, you get the reverse - a USB device disconnect event, followed by the
102device disappearing again.
103
104Bluetooth is autodetected by acer-wmi, so if you do not have a bluetooth module
105installed in your laptop, this file won't exist (please be aware that it is
106quite common for Acer not to fit bluetooth to their laptops - so just because
107you have a bluetooth button on the laptop, doesn't mean that bluetooth is
108installed).
109
110For the adventurously minded - if you want to buy an internal bluetooth
111module off the internet that is compatible with your laptop and fit it, then
112it will work just fine with acer-wmi.
113
114Bluetooth is exposed through rfkill.
115
1163G
117**
118
1193G is currently not autodetected, so the 'threeg' file is always created under
120sysfs. So far, no-one in possession of an Acer laptop with 3G built-in appears to
121have tried Linux, or reported back, so we don't have any information on this.
122
123If you have an Acer laptop that does have a 3G card in, please contact me so we
124can properly detect these, and find out a bit more about them.
125
126To read the status of the 3G card (0=off, 1=on):
127cat /sys/devices/platform/acer-wmi/threeg
128
129To enable the 3G card:
130echo 1 > /sys/devices/platform/acer-wmi/threeg
131
132To disable the 3G card:
133echo 0 > /sys/devices/platform/acer-wmi/threeg
134
135To set the state of the 3G card when loading acer-wmi, pass:
136threeg=X (where X is 0 or 1)
137
138Mail LED
139********
140
141This can be found in most older Acer laptops supported by acer-wmi, and many
142newer ones - it is built into the 'mail' button, and blinks when active.
143
144On newer (WMID) laptops though, we have no way of detecting the mail LED. If
145your laptop identifies itself in dmesg as a WMID model, then please try loading
146acer_acpi with:
147
148force_series=2490
149
150This will use a known alternative method of reading/ writing the mail LED. If
151it works, please report back to me with the DMI data from your laptop so this
152can be added to acer-wmi.
153
154The LED is exposed through the LED subsystem, and can be found in:
155
156/sys/devices/platform/acer-wmi/leds/acer-wmi::mail/
157
158The mail LED is autodetected, so if you don't have one, the LED device won't
159be registered.
160
161Backlight
162*********
163
164The backlight brightness control is available on all acer-wmi supported
165hardware. The maximum brightness level is usually 15, but on some newer laptops
166it's 10 (this is again autodetected).
167
168The backlight is exposed through the backlight subsystem, and can be found in:
169

1The Intel MID PTI project is HW implemented in Intel Atom
2system-on-a-chip designs based on the Parallel Trace
3Interface for MIPI P1149.7 cJTAG standard. The kernel solution
4for this platform involves the following files:
5
6./include/linux/pti.h
7./drivers/.../n_tracesink.h
8./drivers/.../n_tracerouter.c
9./drivers/.../n_tracesink.c
10./drivers/.../pti.c
11
12pti.c is the driver that enables various debugging features
13popular on platforms from certain mobile manufacturers.
14n_tracerouter.c and n_tracesink.c allow extra system information to
15be collected and routed to the pti driver, such as trace
16debugging data from a modem. Although n_tracerouter
17and n_tracesink are a part of the complete PTI solution,
18these two line disciplines can work separately from
19pti.c and route any data stream from one /dev/tty node
20to another /dev/tty node via kernel-space. This provides
21a stable, reliable connection that will not break unless
22the user-space application shuts down (plus avoids
23kernel->user->kernel context switch overheads of routing
24data).
25
26An 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
37Below is example pseudo-code on how a 'privileged' application
38can hook up n_tracerouter and n_tracesink to any tty on
39a system. 'Privileged' means the application has enough
40privileges to successfully manipulate the ldisc drivers
41but is not just blindly executing as 'root'. Keep in mind
42the use of ioctl(,TIOCSETD,) is not specific to the n_tracerouter
43and n_tracesink line discpline drivers but is a generic
44operation for a program to use a line discpline driver
45on a tty port other than the default n_tty.

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
75 - 2 Time stamp external triggers, programmable polarity (opt. interrupt)
76 - 2 Alarm registers (optional interrupt)
77 - 3 Periodic signals (optional interrupt)
78
79 + National DP83640
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
84 - GPIO outputs can produce periodic signals
85 - 1 interrupt pin
86
87 + Intel IXP465
88 - Auxiliary Slave/Master Mode Snapshot (optional interrupt)
89 - Target Time (optional interrupt)

54 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
55 Everyone is permitted to copy and distribute verbatim copies
56 of this license document, but changing it is not allowed.
57
58 Preamble
59
60 The licenses for most software are designed to take away your
61freedom to share and change it. By contrast, the GNU General Public
62License is intended to guarantee your freedom to share and change free
63software--to make sure the software is free for all its users. This
64General Public License applies to most of the Free Software
65Foundation's software and to any other program whose authors commit to
66using it. (Some other Free Software Foundation software is covered by
67the GNU Lesser General Public License instead.) You can apply it to
68your programs, too.
69
70 When we speak of free software, we are referring to freedom, not
71price. Our General Public Licenses are designed to make sure that you
72have the freedom to distribute copies of free software (and charge for
73this service if you wish), that you receive source code or can get it
74if you want it, that you can change the software or use pieces of it
75in 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
78anyone to deny you these rights or to ask you to surrender the rights.
79These restrictions translate to certain responsibilities for you if you
80distribute copies of the software, or if you modify it.
81
82 For example, if you distribute copies of such a program, whether
83gratis or for a fee, you must give the recipients all the rights that
84you have. You must make sure that they, too, receive or can get the
85source code. And you must show them these terms so they know their
86rights.
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,
90distribute and/or modify the software.
91
92 Also, for each author's protection and ours, we want to make certain
93that everyone understands that there is no warranty for this free
94software. If the software is modified by someone else and passed on, we
95want its recipients to know that what they have is not the original, so
96that any problems introduced by others will not reflect on the original
97authors' reputations.
98
99 Finally, any free program is threatened constantly by software
100patents. We wish to avoid the danger that redistributors of a free
101program will individually obtain patent licenses, in effect making the
102program proprietary. To prevent this, we have made it clear that any
103patent must be licensed for everyone's free use or not licensed at all.
104
105 The precise terms and conditions for copying, distribution and
106modification 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
112a notice placed by the copyright holder saying it may be distributed
113under the terms of this General Public License. The "Program", below,
114refers to any such program or work, and a "work based on the Program"
115means either the Program or any derivative work under copyright law:
116that is to say, a work containing the Program or a portion of it,
117either verbatim or with modifications and/or translated into another
118language. (Hereinafter, translation is included without limitation in
119the term "modification".) Each licensee is addressed as "you".
120
121Activities other than copying, distribution and modification are not
122covered by this License; they are outside its scope. The act of
123running the Program is not restricted, and the output from the Program
124is covered only if its contents constitute a work based on the
125Program (independent of having been made by running the Program).
126Whether that is true depends on what the Program does.
127
128 1. You may copy and distribute verbatim copies of the Program's
129source code as you receive it, in any medium, provided that you
130conspicuously and appropriately publish on each copy an appropriate
131copyright notice and disclaimer of warranty; keep intact all the
132notices that refer to this License and to the absence of any warranty;
133and give any other recipients of the Program a copy of this License
134along with the Program.
135
136You may charge a fee for the physical act of transferring a copy, and
137you 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
140of it, thus forming a work based on the Program, and copy and
141distribute such modifications or work under the terms of Section 1
142above, 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
163These requirements apply to the modified work as a whole. If
164identifiable sections of that work are not derived from the Program,
165and can be reasonably considered independent and separate works in
166themselves, then this License, and its terms, do not apply to those
167sections when you distribute them as separate works. But when you
168distribute the same sections as part of a whole which is a work based
169on the Program, the distribution of the whole must be on the terms of
170this License, whose permissions for other licensees extend to the
171entire whole, and thus to each and every part regardless of who wrote it.
172
173Thus, it is not the intent of this section to claim rights or contest
174your rights to work written entirely by you; rather, the intent is to
175exercise the right to control the distribution of derivative or
176collective works based on the Program.
177
178In addition, mere aggregation of another work not based on the Program
179with the Program (or with a work based on the Program) on a volume of
180a storage or distribution medium does not bring the other work under
181the scope of this License.
182
183 3. You may copy and distribute the Program (or a work based on it,
184under Section 2) in object code or executable form under the terms of
185Sections 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
204The source code for a work means the preferred form of the work for
205making modifications to it. For an executable work, complete source
206code means all the source code for all modules it contains, plus any
207associated interface definition files, plus the scripts used to
208control compilation and installation of the executable. However, as a
209special exception, the source code distributed need not include
210anything that is normally distributed (in either source or binary
211form) with the major components (compiler, kernel, and so on) of the
212operating system on which the executable runs, unless that component
213itself accompanies the executable.
214
215If distribution of executable or object code is made by offering
216access to copy from a designated place, then offering equivalent
217access to copy the source code from the same place counts as
218distribution of the source code, even though third parties are not
219compelled to copy the source along with the object code.
220
221 4. You may not copy, modify, sublicense, or distribute the Program
222except as expressly provided under this License. Any attempt
223otherwise to copy, modify, sublicense or distribute the Program is
224void, and will automatically terminate your rights under this License.
225However, parties who have received copies, or rights, from you under
226this License will not have their licenses terminated so long as such
227parties remain in full compliance.
228
229 5. You are not required to accept this License, since you have not
230signed it. However, nothing else grants you permission to modify or
231distribute the Program or its derivative works. These actions are
232prohibited by law if you do not accept this License. Therefore, by
233modifying or distributing the Program (or any work based on the
234Program), you indicate your acceptance of this License to do so, and
235all its terms and conditions for copying, distributing or modifying
236the Program or works based on it.
237
238 6. Each time you redistribute the Program (or any work based on the
239Program), the recipient automatically receives a license from the
240original licensor to copy, distribute or modify the Program subject to
241these terms and conditions. You may not impose any further
242restrictions on the recipients' exercise of the rights granted herein.
243You are not responsible for enforcing compliance by third parties to
244this License.
245
246 7. If, as a consequence of a court judgment or allegation of patent
247infringement or for any other reason (not limited to patent issues),
248conditions are imposed on you (whether by court order, agreement or
249otherwise) that contradict the conditions of this License, they do not
250excuse you from the conditions of this License. If you cannot
251distribute so as to satisfy simultaneously your obligations under this
252License and any other pertinent obligations, then as a consequence you
253may not distribute the Program at all. For example, if a patent
254license would not permit royalty-free redistribution of the Program by
255all those who receive copies directly or indirectly through you, then
256the only way you could satisfy both it and this License would be to
257refrain entirely from distribution of the Program.
258
259If any portion of this section is held invalid or unenforceable under
260any particular circumstance, the balance of the section is intended to
261apply and the section as a whole is intended to apply in other
262circumstances.
263
264It is not the purpose of this section to induce you to infringe any
265patents or other property right claims or to contest validity of any
266such claims; this section has the sole purpose of protecting the
267integrity of the free software distribution system, which is
268implemented by public license practices. Many people have made
269generous contributions to the wide range of software distributed
270through that system in reliance on consistent application of that
271system; it is up to the author/donor to decide if he or she is willing
272to distribute software through any other system and a licensee cannot
273impose that choice.
274
275This section is intended to make thoroughly clear what is believed to
276be a consequence of the rest of this License.
277
278 8. If the distribution and/or use of the Program is restricted in
279certain countries either by patents or by copyrighted interfaces, the
280original copyright holder who places the Program under this License
281may add an explicit geographical distribution limitation excluding
282those countries, so that distribution is permitted only in or among
283countries not thus excluded. In such case, this License incorporates
284the limitation as if written in the body of this License.
285
286 9. The Free Software Foundation may publish revised and/or new versions
287of the General Public License from time to time. Such new versions will
288be similar in spirit to the present version, but may differ in detail to
289address new problems or concerns.
290
291Each version is given a distinguishing version number. If the Program
292specifies a version number of this License which applies to it and "any
293later version", you have the option of following the terms and conditions
294either of that version or of any later version published by the Free
295Software Foundation. If the Program does not specify a version number of
296this License, you may choose any version ever published by the Free Software
297Foundation.
298
299 10. If you wish to incorporate parts of the Program into other free
300programs whose distribution conditions are different, write to the author
301to ask for permission. For software which is copyrighted by the Free
302Software Foundation, write to the Free Software Foundation; we sometimes
303make exceptions for this. Our decision will be guided by the two goals
304of preserving the free status of all derivatives of our free software and
305of 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
310FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
311OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
312PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
313OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
314MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
315TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
316PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
317REPAIR OR CORRECTION.
318
319 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
320WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
321REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
322INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
323OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
324TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
325YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
326PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
327POSSIBILITY OF SUCH DAMAGES.

1Linux USB Video Class (UVC) driver
2==================================
3
4This file documents some driver-specific aspects of the UVC driver, such as
5driver-specific ioctls and implementation notes.

7Questions and remarks can be sent to the Linux UVC development mailing list at
8linux-uvc-devel@lists.berlios.de.

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

102---- UVCIOC_CTRL_MAP - Map a UVC control to a V4L2 control ----
103
104Argument: struct uvc_xu_control_mapping
105
106Description:
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
125Return value:
126 On success 0 is returned. On error -1 is returned and errno is set
127 appropriately.

175Argument: struct uvc_xu_control_query
176
177Description:
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
216Return 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.
227 EBADRQC
228 The given request is not supported by the given control.
229 EFAULT
230 The data pointer references an inaccessible memory area.

1MOTIVATION
2
3Cleancache is a new optional feature provided by the VFS layer that
4potentially dramatically increases page cache effectiveness for
5many workloads in many environments at a negligible cost.
6
7Cleancache can be thought of as a page-granularity victim cache for clean
8pages that the kernel's pageframe replacement algorithm (PFRA) would like
9to keep around, but can't since there isn't enough memory. So when the
10PFRA "evicts" a page, it first attempts to use cleancache code to
11put the data contained in that page into "transcendent memory", memory
12that is not directly accessible or addressable by the kernel and is
13of unknown and possibly time-varying size.
14
15Later, when a cleancache-enabled filesystem wishes to access a page
16in a file on disk, it first checks cleancache to see if it already
17contains it; if it does, the page of data is copied into the kernel
18and a disk access is avoided.
19
20Transcendent memory "drivers" for cleancache are currently implemented
21in Xen (using hypervisor memory) and zcache (using in-kernel compressed
22memory) and other implementations are in development.
23
24FAQs are included below.
25
26IMPLEMENTATION OVERVIEW
27
28A cleancache "backend" that provides transcendent memory registers itself
29to the kernel's cleancache "frontend" by calling cleancache_register_ops,
30passing a pointer to a cleancache_ops structure with funcs set appropriately.
31Note that cleancache_register_ops returns the previous settings so that
32chaining can be performed if desired. The functions provided must conform to
33certain semantics as follows:
34
35Most important, cleancache is "ephemeral". Pages which are copied into
36cleancache have an indefinite lifetime which is completely unknowable
37by the kernel and so may or may not still be in cleancache at any later time.
38Thus, as its name implies, cleancache is not suitable for dirty pages.
39Cleancache has complete discretion over what pages to preserve and what
40pages to discard and when.
41
42Mounting a cleancache-enabled filesystem should call "init_fs" to obtain a
43pool id which, if positive, must be saved in the filesystem's superblock;
44a negative return value indicates failure. A "put_page" will copy a
45(presumably about-to-be-evicted) page into cleancache and associate it with
46the pool id, a file key, and a page index into the file. (The combination
47of a pool id, a file key, and an index is sometimes called a "handle".)
48A "get_page" will copy the page, if found, from cleancache into kernel memory.
49A "flush_page" will ensure the page no longer is present in cleancache;
50a "flush_inode" will flush all pages associated with the specified file;
51and, when a filesystem is unmounted, a "flush_fs" will flush all pages in
52all files specified by the given pool id and also surrender the pool id.
53
54An "init_shared_fs", like init_fs, obtains a pool id but tells cleancache
55to treat the pool as shared using a 128-bit UUID as a key. On systems
56that may run multiple kernels (such as hard partitioned or virtualized
57systems) that may share a clustered filesystem, and where cleancache
58may be shared among those kernels, calls to init_shared_fs that specify the
59same UUID will receive the same pool id, thus allowing the pages to
60be shared. Note that any security requirements must be imposed outside
61of the kernel (e.g. by "tools" that control cleancache). Or a
62cleancache implementation can simply disable shared_init by always
63returning a negative value.
64
65If a get_page is successful on a non-shared pool, the page is flushed (thus
66making cleancache an "exclusive" cache). On a shared pool, the page
67is NOT flushed on a successful get_page so that it remains accessible to
68other sharers. The kernel is responsible for ensuring coherency between
69cleancache (shared or not), the page cache, and the filesystem, using
70cleancache flush operations as required.
71
72Note that cleancache must enforce put-put-get coherency and get-get
73coherency. For the former, if two puts are made to the same handle but
74with different data, say AAA by the first put and BBB by the second, a
75subsequent get can never return the stale data (AAA). For get-get coherency,
76if a get for a given handle fails, subsequent gets for that handle will
77never succeed unless preceded by a successful put with that handle.
78
79Last, cleancache provides no SMP serialization guarantees; if two
80different Linux threads are simultaneously putting and flushing a page
81with the same handle, the results are indeterminate. Callers must
82lock the page to ensure serial behavior.
83
84CLEANCACHE PERFORMANCE METRICS
85
86Cleancache monitoring is done by sysfs files in the
87/sys/kernel/mm/cleancache directory. The effectiveness of cleancache
88can be measured (across all filesystems) with:
89
90succ_gets - number of gets that were successful
91failed_gets - number of gets that failed
92puts - number of puts attempted (all "succeed")
93flushes - number of flushes attempted
94
95A backend implementatation may provide additional metrics.

97FAQ
98
991) Where's the value? (Andrew Morton)
100
101Cleancache provides a significant performance benefit to many workloads
102in many environments with negligible overhead by improving the
103effectiveness of the pagecache. Clean pagecache pages are
104saved in transcendent memory (RAM that is otherwise not directly
105addressable to the kernel); fetching those pages later avoids "refaults"
106and thus disk reads.
107
108Cleancache (and its sister code "frontswap") provide interfaces for
109this transcendent memory (aka "tmem"), which conceptually lies between
110fast kernel-directly-addressable RAM and slower DMA/asynchronous devices.
111Disallowing direct kernel or userland reads/writes to tmem
112is ideal when data is transformed to a different form and size (such
113as with compression) or secretly moved (as might be useful for write-
114balancing for some RAM-like devices). Evicted page-cache pages (and
115swap pages) are a great use for this kind of slower-than-RAM-but-much-
116faster-than-disk transcendent memory, and the cleancache (and frontswap)
117"page-object-oriented" specification provides a nice way to read and
118write -- and indirectly "name" -- the pages.
119
120In the virtual case, the whole point of virtualization is to statistically
121multiplex physical resources across the varying demands of multiple
122virtual machines. This is really hard to do with RAM and efforts to
123do it well with no kernel change have essentially failed (except in some
124well-publicized special-case workloads). Cleancache -- and frontswap --
125with a fairly small impact on the kernel, provide a huge amount
126of flexibility for more dynamic, flexible RAM multiplexing.
127Specifically, the Xen Transcendent Memory backend allows otherwise
128"fallow" hypervisor-owned RAM to not only be "time-shared" between multiple
129virtual machines, but the pages can be compressed and deduplicated to
130optimize RAM utilization. And when guest OS's are induced to surrender
131underutilized RAM (e.g. with "self-ballooning"), page cache pages
132are the first to go, and cleancache allows those pages to be
133saved and reclaimed if overall host system memory conditions allow.
134
135And the identical interface used for cleancache can be used in
136physical systems as well. The zcache driver acts as a memory-hungry
137device that stores pages of data in a compressed state. And
138the proposed "RAMster" driver shares RAM across multiple physical
139systems.
140
1412) Why does cleancache have its sticky fingers so deep inside the
142 filesystems and VFS? (Andrew Morton and Christoph Hellwig)
143
144The core hooks for cleancache in VFS are in most cases a single line
145and the minimum set are placed precisely where needed to maintain
146coherency (via cleancache_flush operations) between cleancache,
147the page cache, and disk. All hooks compile into nothingness if
148cleancache is config'ed off and turn into a function-pointer-
149compare-to-NULL if config'ed on but no backend claims the ops
150functions, or to a compare-struct-element-to-negative if a
151backend claims the ops functions but a filesystem doesn't enable
152cleancache.
153
154Some filesystems are built entirely on top of VFS and the hooks
155in VFS are sufficient, so don't require an "init_fs" hook; the
156initial implementation of cleancache didn't provide this hook.
157But for some filesystems (such as btrfs), the VFS hooks are
158incomplete and one or more hooks in fs-specific code are required.
159And for some other filesystems, such as tmpfs, cleancache may
160be counterproductive. So it seemed prudent to require a filesystem
161to "opt in" to use cleancache, which requires adding a hook in
162each filesystem. Not all filesystems are supported by cleancache
163only because they haven't been tested. The existing set should
164be sufficient to validate the concept, the opt-in approach means
165that untested filesystems are not affected, and the hooks in the
166existing filesystems should make it very easy to add more
167filesystems in the future.
168
169The total impact of the hooks to existing fs and mm files is only
170about 40 lines added (not counting comments and blank lines).
171
1723) 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
176The one-page-at-a-time copy semantics simplifies the implementation
177on both the frontend and backend and also allows the backend to
178do fancy things on-the-fly like page compression and
179page deduplication. And since the data is "gone" (copied into/out
180of the pageframe) before the cleancache get/put call returns,
181a great deal of race conditions and potential coherency issues
182are avoided. While the interface seems odd for a "real device"
183or for real kernel-addressable RAM, it makes perfect sense for
184transcendent memory.
185
1864) Why is non-shared cleancache "exclusive"? And where is the
187 page "flushed" after a "get"? (Minchan Kim)
188
189The main reason is to free up space in transcendent memory and
190to avoid unnecessary cleancache_flush calls. If you want inclusive,
191the page can be "put" immediately following the "get". If
192put-after-get for inclusive becomes common, the interface could
193be easily extended to add a "get_no_flush" call.
194
195The flush is done by the cleancache backend implementation.
196
1975) What's the performance impact?
198
199Performance analysis has been presented at OLS'09 and LCA'10.
200Briefly, performance gains can be significant on most workloads,
201especially when memory pressure is high (e.g. when RAM is
202overcommitted in a virtual workload); and because the hooks are
203invoked primarily in place of or in addition to a disk read/write,
204overhead is negligible even in worst case workloads. Basically
205cleancache replaces I/O with memory-copy-CPU-overhead; on older
206single-core systems with slow memory-copy speeds, cleancache
207has little value, but in newer multicore machines, especially
208consolidated/virtualized machines, it has great value.
209
2106) How do I add cleancache support for filesystem X? (Boaz Harrash)
211
212Filesystems that are well-behaved and conform to certain
213restrictions can utilize cleancache simply by making a call to
214cleancache_init_fs at mount time. Unusual, misbehaving, or
215poorly layered filesystems must either add additional hooks
216and/or undergo extensive additional testing... or should just
217not enable the optional cleancache.
218
219Some 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
2407) Why not use the KVA of the inode as the key? (Christoph Hellwig)
241
242If cleancache would use the inode virtual address instead of
243inode/filehandle, the pool id could be eliminated. But, this
244won't work because cleancache retains pagecache data pages
245persistently even when the inode has been pruned from the
246inode unused list, and only flushes the data page if the file
247gets removed/truncated. So if cleancache used the inode kva,
248there would be potential coherency issues if/when the inode
249kva is reused for a different file. Alternately, if cleancache
250flushed the pages when the inode kva was freed, much of the value
251of cleancache would be lost because the cache of pages in cleanache
252is potentially much larger than the kernel pagecache and is most
253useful if the pages survive inode cache removal.
254
2558) Why is a global variable required?
256
257The cleancache_enabled flag is checked in all of the frequently-used
258cleancache hooks. The alternative is a function call to check a static
259variable. Since cleancache is enabled dynamically at runtime, systems
260that don't enable cleancache would suffer thousands (possibly
261tens-of-thousands) of unnecessary function calls per second. So the
262global variable allows cleancache to be enabled by default at compile
263time, but have insignificant performance impact when cleancache remains
264disabled at runtime.
265
2669) Does cleanache work with KVM?
267
268The memory model of KVM is sufficiently different that a cleancache
269backend may have less value for KVM. This remains to be tested,
270especially in an overcommitted system.
271
27210) Does cleancache work in userspace? It sounds useful for
273 memory hungry caches like web browsers. (Jamie Lokier)
274
275No plans yet, though we agree it sounds useful, at least for
276apps that bypass the page cache (e.g. O_DIRECT).

386
387Because the work functions are executed by generic worker threads
388there are a few tricks needed to shed some light on misbehaving
389workqueue users.
390
391Worker threads show up in the process list as:
392
393root 5671 0.0 0.0 0 0 ? S 12:07 0:00 [kworker/0:1]
394root 5672 0.0 0.0 0 0 ? S 12:07 0:00 [kworker/1:2]
395root 5673 0.0 0.0 0 0 ? S 12:12 0:00 [kworker/0:0]
396root 5674 0.0 0.0 0 0 ? S 12:13 0:00 [kworker/1:0]
397
398If kworkers are going crazy (using too much cpu), there are two types
399of possible problems:
400
401 1. Something beeing scheduled in rapid succession
402 2. A single work item that consumes lots of cpu cycles
403
404The 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
411If something is busy looping on work queueing, it would be dominating
412the output and the offender can be determined with the work item
413function.
414
415For the second type of problems it should be possible to just check
416the stack trace of the offending worker thread.
417
418 $ cat /proc/THE_OFFENDING_KWORKER/stack
419
420The work item's function should be trivially visible in the stack
421trace.
