V4L/DVB (3599a): Move drivers/usb/media to drivers/media/video
Because of historic reasons, there are two separate directories with V4L stuff. Most drivers are located at driver/media/video. However, some code for USB Webcams were inserted under drivers/usb/media. This makes difficult for module authors to know were things should be. Also, makes Kconfig menu confusing for normal users. This patch moves all V4L content under drivers/usb/media to drivers/media/video, and fixes Kconfig/Makefile entries.

1/* A driver for the D-Link DSB-R100 USB radio. The R100 plugs
2 into both the USB and an analog audio input, so this thing
3 only deals with initialisation and frequency setting, the
4 audio data has to be handled by a sound driver.
5
6 Major issue: I can't find out where the device reports the signal
7 strength, and indeed the windows software appearantly just looks
8 at the stereo indicator as well. So, scanning will only find
9 stereo stations. Sad, but I can't help it.
10
11 Also, the windows program sends oodles of messages over to the
12 device, and I couldn't figure out their meaning. My suspicion
13 is that they don't have any:-)

31The main webpage for the Philips driver is at the address above. It contains
32a lot of extra information, a FAQ, and the binary plugin 'PWCX'. This plugin
33contains decompression routines that allow you to use higher image sizes and
34framerates; in addition the webcam uses less bandwidth on the USB bus (handy
35if you want to run more than 1 camera simultaneously). These routines fall
36under a NDA, and may therefor not be distributed as source; however, its use
37is completely optional.
38
39You can build this code either into your kernel, or as a module. I recommend
40the latter, since it makes troubleshooting a lot easier. The built-in
41microphone is supported through the USB Audio class.
42
43When you load the module you can set some default settings for the
44camera; some programs depend on a particular image-size or -format and
45don't know how to set it properly in the driver. The options are:
46
47size
48 Can be one of 'sqcif', 'qsif', 'qcif', 'sif', 'cif' or
49 'vga', for an image size of resp. 128x96, 160x120, 176x144,
50 320x240, 352x288 and 640x480 (of course, only for those cameras that
51 support these resolutions).
52
53fps
54 Specifies the desired framerate. Is an integer in the range of 4-30.
55
56fbufs
57 This paramter specifies the number of internal buffers to use for storing
58 frames from the cam. This will help if the process that reads images from
59 the cam is a bit slow or momentarely busy. However, on slow machines it
60 only introduces lag, so choose carefully. The default is 3, which is
61 reasonable. You can set it between 2 and 5.
62
63mbufs
64 This is an integer between 1 and 10. It will tell the module the number of
65 buffers to reserve for mmap(), VIDIOCCGMBUF, VIDIOCMCAPTURE and friends.
66 The default is 2, which is adequate for most applications (double
67 buffering).
68
69 Should you experience a lot of 'Dumping frame...' messages during
70 grabbing with a tool that uses mmap(), you might want to increase if.
71 However, it doesn't really buffer images, it just gives you a bit more
72 slack when your program is behind. But you need a multi-threaded or
73 forked program to really take advantage of these buffers.
74
75 The absolute maximum is 10, but don't set it too high! Every buffer takes
76 up 460 KB of RAM, so unless you have a lot of memory setting this to
77 something more than 4 is an absolute waste. This memory is only
78 allocated during open(), so nothing is wasted when the camera is not in
79 use.
80
81power_save
82 When power_save is enabled (set to 1), the module will try to shut down
83 the cam on close() and re-activate on open(). This will save power and
84 turn off the LED. Not all cameras support this though (the 645 and 646
85 don't have power saving at all), and some models don't work either (they
86 will shut down, but never wake up). Consider this experimental. By
87 default this option is disabled.
88
89compression (only useful with the plugin)
90 With this option you can control the compression factor that the camera
91 uses to squeeze the image through the USB bus. You can set the
92 parameter between 0 and 3:
93 0 = prefer uncompressed images; if the requested mode is not available
94 in an uncompressed format, the driver will silently switch to low
95 compression.
96 1 = low compression.
97 2 = medium compression.
98 3 = high compression.
99
100 High compression takes less bandwidth of course, but it could also
101 introduce some unwanted artefacts. The default is 2, medium compression.
102 See the FAQ on the website for an overview of which modes require
103 compression.
104
105 The compression parameter does not apply to the 645 and 646 cameras
106 and OEM models derived from those (only a few). Most cams honour this
107 parameter.
108
109leds
110 This settings takes 2 integers, that define the on/off time for the LED
111 (in milliseconds). One of the interesting things that you can do with
112 this is let the LED blink while the camera is in use. This:
113
114 leds=500,500
115
116 will blink the LED once every second. But with:
117
118 leds=0,0
119
120 the LED never goes on, making it suitable for silent surveillance.
121
122 By default the camera's LED is on solid while in use, and turned off
123 when the camera is not used anymore.
124
125 This parameter works only with the ToUCam range of cameras (720, 730, 740,
126 750) and OEMs. For other cameras this command is silently ignored, and
127 the LED cannot be controlled.
128
129 Finally: this parameters does not take effect UNTIL the first time you
130 open the camera device. Until then, the LED remains on.
131
132dev_hint
133 A long standing problem with USB devices is their dynamic nature: you
134 never know what device a camera gets assigned; it depends on module load
135 order, the hub configuration, the order in which devices are plugged in,
136 and the phase of the moon (i.e. it can be random). With this option you
137 can give the driver a hint as to what video device node (/dev/videoX) it
138 should use with a specific camera. This is also handy if you have two
139 cameras of the same model.
140
141 A camera is specified by its type (the number from the camera model,
142 like PCA645, PCVC750VC, etc) and optionally the serial number (visible
143 in /proc/bus/usb/devices). A hint consists of a string with the following
144 format:
145
146 [type[.serialnumber]:]node
147
148 The square brackets mean that both the type and the serialnumber are
149 optional, but a serialnumber cannot be specified without a type (which
150 would be rather pointless). The serialnumber is separated from the type
151 by a '.'; the node number by a ':'.
152
153 This somewhat cryptic syntax is best explained by a few examples:
154
155 dev_hint=3,5 The first detected cam gets assigned
156 /dev/video3, the second /dev/video5. Any
157 other cameras will get the first free
158 available slot (see below).
159
160 dev_hint=645:1,680:2 The PCA645 camera will get /dev/video1,
161 and a PCVC680 /dev/video2.
162
163 dev_hint=645.0123:3,645.4567:0 The PCA645 camera with serialnumber
164 0123 goes to /dev/video3, the same
165 camera model with the 4567 serial
166 gets /dev/video0.
167
168 dev_hint=750:1,4,5,6 The PCVC750 camera will get /dev/video1, the
169 next 3 Philips cams will use /dev/video4
170 through /dev/video6.
171
172 Some points worth knowing:
173 - Serialnumbers are case sensitive and must be written full, including
174 leading zeroes (it's treated as a string).
175 - If a device node is already occupied, registration will fail and
176 the webcam is not available.
177 - You can have up to 64 video devices; be sure to make enough device
178 nodes in /dev if you want to spread the numbers (this does not apply
179 to devfs). After /dev/video9 comes /dev/video10 (not /dev/videoA).
180 - If a camera does not match any dev_hint, it will simply get assigned
181 the first available device node, just as it used to be.
182
183trace
184 In order to better detect problems, it is now possible to turn on a
185 'trace' of some of the calls the module makes; it logs all items in your
186 kernel log at debug level.
187
188 The trace variable is a bitmask; each bit represents a certain feature.
189 If you want to trace something, look up the bit value(s) in the table
190 below, add the values together and supply that to the trace variable.
191
192 Value Value Description Default
193 (dec) (hex)
194 1 0x1 Module initialization; this will log messages On
195 while loading and unloading the module
196
197 2 0x2 probe() and disconnect() traces On
198
199 4 0x4 Trace open() and close() calls Off
200
201 8 0x8 read(), mmap() and associated ioctl() calls Off
202
203 16 0x10 Memory allocation of buffers, etc. Off
204
205 32 0x20 Showing underflow, overflow and Dumping frame On
206 messages
207
208 64 0x40 Show viewport and image sizes Off
209
210 128 0x80 PWCX debugging Off
211
212 For example, to trace the open() & read() fuctions, sum 8 + 4 = 12,
213 so you would supply trace=12 during insmod or modprobe. If
214 you want to turn the initialization and probing tracing off, set trace=0.
215 The default value for trace is 35 (0x23).
216
217
218
219Example:
220
221 # modprobe pwc size=cif fps=15 power_save=1
222
223The fbufs, mbufs and trace parameters are global and apply to all connected
224cameras. Each camera has its own set of buffers.
225
226size and fps only specify defaults when you open() the device; this is to
227accommodate some tools that don't set the size. You can change these
228settings after open() with the Video4Linux ioctl() calls. The default of
229defaults is QCIF size at 10 fps.
230
231The compression parameter is semiglobal; it sets the initial compression
232preference for all camera's, but this parameter can be set per camera with
233the VIDIOCPWCSCQUAL ioctl() call.
234
235All parameters are optional.

29 This code forms the interface between the USB layers and the Philips
30 specific stuff. Some adanved stuff of the driver falls under an
31 NDA, signed between me and Philips B.V., Eindhoven, the Netherlands, and
32 is thus not distributed in source form. The binary pwcx.o module
33 contains the code that falls under the NDA.
34
35 In case you're wondering: 'pwc' stands for "Philips WebCam", but
36 I really didn't want to type 'philips_web_cam' every time (I'm lazy as
37 any Linux kernel hacker, but I don't like uncomprehensible abbreviations
38 without explanation).
39
40 Oh yes, convention: to disctinguish between all the various pointers to
41 device-structures, I use these names for the pointer variables:
42 udev: struct usb_device *
43 vdev: struct video_device *
44 pdev: struct pwc_devive *

171/* Okay, this is some magic that I worked out and the reasoning behind it...
172
173 The biggest problem with any USB device is of course: "what to do
174 when the user unplugs the device while it is in use by an application?"
175 We have several options:
176 1) Curse them with the 7 plagues when they do (requires divine intervention)
177 2) Tell them not to (won't work: they'll do it anyway)
178 3) Oops the kernel (this will have a negative effect on a user's uptime)
179 4) Do something sensible.
180
181 Of course, we go for option 4.
182
183 It happens that this device will be linked to two times, once from
184 usb_device and once from the video_device in their respective 'private'
185 pointers. This is done when the device is probed() and all initialization
186 succeeded. The pwc_device struct links back to both structures.
187
188 When a device is unplugged while in use it will be removed from the
189 list of known USB devices; I also de-register it as a V4L device, but
190 unfortunately I can't free the memory since the struct is still in use
191 by the file descriptor. This free-ing is then deferend until the first
192 opportunity. Crude, but it works.
193
194 A small 'advantage' is that if a user unplugs the cam and plugs it back
195 in, it should get assigned the same video device minor, but unfortunately
196 it's non-trivial to re-link the cam back to the video device... (that
197 would surely be magic! :))

410/* The frame & image buffer mess.
411
412 Yes, this is a mess. Well, it used to be simple, but alas... In this
413 module, 3 buffers schemes are used to get the data from the USB bus to
414 the user program. The first scheme involves the ISO buffers (called thus
415 since they transport ISO data from the USB controller), and not really
416 interesting. Suffices to say the data from this buffer is quickly
417 gathered in an interrupt handler (pwc_isoc_handler) and placed into the
418 frame buffer.
419
420 The frame buffer is the second scheme, and is the central element here.
421 It collects the data from a single frame from the camera (hence, the
422 name). Frames are delimited by the USB camera with a short USB packet,
423 so that's easy to detect. The frame buffers form a list that is filled
424 by the camera+USB controller and drained by the user process through
425 either read() or mmap().
426
427 The image buffer is the third scheme, in which frames are decompressed
428 and converted into planar format. For mmap() there is more than
429 one image buffer available.
430
431 The frame buffers provide the image buffering. In case the user process
432 is a bit slow, this introduces lag and some undesired side-effects.
433 The problem arises when the frame buffer is full. I used to drop the last
434 frame, which makes the data in the queue stale very quickly. But dropping
435 the frame at the head of the queue proved to be a litte bit more difficult.
436 I tried a circular linked scheme, but this introduced more problems than
437 it solved.
438
439 Because filling and draining are completely asynchronous processes, this
440 requires some fiddling with pointers and mutexes.
441
442 Eventually, I came up with a system with 2 lists: an 'empty' frame list
443 and a 'full' frame list:
444 * Initially, all frame buffers but one are on the 'empty' list; the one
445 remaining buffer is our initial fill frame.
446 * If a frame is needed for filling, we try to take it from the 'empty'
447 list, unless that list is empty, in which case we take the buffer at
448 the head of the 'full' list.
449 * When our fill buffer has been filled, it is appended to the 'full'
450 list.
451 * If a frame is needed by read() or mmap(), it is taken from the head of
452 the 'full' list, handled, and then appended to the 'empty' list. If no
453 buffer is present on the 'full' list, we wait.
454 The advantage is that the buffer that is currently being decompressed/
455 converted, is on neither list, and thus not in our way (any other scheme
456 I tried had the problem of old data lingering in the queue).
457
458 Whatever strategy you choose, it always remains a tradeoff: with more
459 frame buffers the chances of a missed frame are reduced. On the other
460 hand, on slower machines it introduces lag because the queue will
461 always be full.

1159 the need, second there's no mechanism of alerting the
1160 2nd/3rd/... process of events like changing image size.
1161 And I don't see the point of blocking that for the

1163 In multi-threaded environments reading parallel from any

5 driver and thus may have bugs that are not present in the original version.
6 Please send bug reports and support requests to <luc@saillard.org>.
7 The decompression routines have been implemented by reverse-engineering the
8 Nemosoft binary pwcx module. Caveat emptor.

26/* This tables contains entries for the 675/680/690 (Timon) camera, with
27 4 different qualities (no compression, low, medium, high).
28 It lists the bandwidth requirements for said mode by its alternate interface
29 number. An alternate of 0 means that the mode is unavailable.
30
31 There are 6 * 4 * 4 entries:
32 6 different resolutions subqcif, qsif, qcif, sif, cif, vga
33 6 framerates: 5, 10, 15, 20, 25, 30
34 4 compression modi: none, low, medium, high
35
36 When an uncompressed mode is not available, the next available compressed mode
37 will be chosen (unless the decompressor is absent). Sometimes there are only
38 1 or 2 compressed modes available; in that case entries are duplicated.

37 OVERVIEW.
38 This is a small interface that allows you to add support for any CCD/CMOS
39 image sensors connected to the SN9C10X bridges. The entire API is documented
40 below. In the most general case, to support a sensor there are three steps
41 you have to follow:
42 1) define the main "sn9c102_sensor" structure by setting the basic fields;
43 2) write a probing function to be called by the core module when the USB
44 camera is recognized, then add both the USB ids and the name of that
45 function to the two corresponding tables SENSOR_TABLE and ID_TABLE (see
46 below);
47 3) implement the methods that you want/need (and fill the rest of the main
48 structure accordingly).
49 "sn9c102_pas106b.c" is an example of all this stuff. Remember that you do
50 NOT need to touch the source code of the core module for the things to work
51 properly, unless you find bugs or flaws in it. Finally, do not forget to
52 read the V4L2 API for completeness.
53*/

55/*****************************************************************************/
56
57/*
58 Probing functions: on success, you must attach the sensor to the camera
59 by calling sn9c102_attach_sensor() provided below.
60 To enable the I2C communication, you might need to perform a really basic
61 initialization of the SN9C10X chip by using the write function declared
62 ahead.
63 Functions must return 0 on success, the appropriate error otherwise.

297 use this coordinate system from now on. It is assumed the sensor
298 chip can be programmed to capture/transmit a subsection of that
299 array of pixels: we will call this subsection "active window".
300 It is not always true that the largest achievable active window can
301 cover the whole array of pixels. The V4L2 API defines another
302 area called "source rectangle", which, in turn, is a subrectangle of
303 the active window. The SN9C10X chip is always programmed to read the
304 source rectangle.
305 The bounds of both the active window and the source rectangle are
306 specified in the cropcap substructures 'bounds' and 'defrect'.
307 By default, the source rectangle should cover the largest possible
308 area. Again, it is not always true that the largest source rectangle
309 can cover the entire active window, although it is a rare case for
310 the hardware we have. The bounds of the source rectangle _must_ be
311 multiple of 16 and must use the same coordinate system as indicated
312 before; their centers shall align initially.
313 If necessary, the sensor chip must be initialized during init() to
314 set the bounds of the active sensor window; however, by default, it
315 usually covers the largest achievable area (maxwidth x maxheight)
316 of pixels, so no particular initialization is needed, if you have
317 defined the correct default bounds in the structures.
318 See the V4L2 API for further details.
319 NOTE: once you have defined the bounds of the active window
320 (struct cropcap.bounds) you must not change them.anymore.

2 * STV0680 USB Camera Driver, by Kevin Sisson (kjsisson@bellsouth.net)
3 *
4 * Thanks to STMicroelectronics for information on the usb commands, and
5 * to Steve Miller at STM for his help and encouragement while I was
6 * writing this driver.
7 *
8 * This driver is based heavily on the
9 * Endpoints (formerly known as AOX) se401 USB Camera Driver
10 * Copyright (c) 2000 Jeroen B. Vreeken (pe1rxq@amsat.org)
11 *
12 * Still somewhat based on the Linux ov511 driver.

26 * Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
27 *
28 * History:
29 * ver 0.1 October, 2001. Initial attempt.
30 *
31 * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
32 * function, made more stable (?)
33 *
34 * ver 0.21 Nov, 2001. Added gamma correction and white balance,
35 * due to Alexander Schwartz. Still trying to
36 * improve stablility. Moved stuff into stv680.h
37 *
38 * ver 0.22 Nov, 2001. Added sharpen function (by Michael Sweet,
39 * mike@easysw.com) from GIMP, also used in pencam.
40 * Simple, fast, good integer math routine.
41 *
42 * ver 0.23 Dec, 2001 (gkh)
43 * Took out sharpen function, ran code through
44 * Lindent, and did other minor tweaks to get
45 * things to work properly with 2.5.1
46 *
47 * ver 0.24 Jan, 2002 (kjs)
48 * Fixed the problem with webcam crashing after
49 * two pictures. Changed the way pic is halved to
50 * improve quality. Got rid of green line around
51 * frame. Fix brightness reset when changing size
52 * bug. Adjusted gamma filters slightly.
53 *
54 * ver 0.25 Jan, 2002 (kjs)
55 * Fixed a bug in which the driver sometimes attempted
56 * to set to a non-supported size. This allowed
57 * gnomemeeting to work.
58 * Fixed proc entry removal bug.

109 * Actually it seems to be a copy of a shameless copy of the bttv-driver.

111 * no generic kernel-function to do this sort of stuff?)

113 * Yes, it was a shameless copy from the bttv-driver. IIRC, Alan says
114 * there will be one, but apparentely not yet -jerdfelt
