Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

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

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

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

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

+ OVERVIEW.
+ This is a small interface that allows you to add support for any CCD/CMOS
+ image sensors connected to the SN9C10X bridges. The entire API is documented
+ below. In the most general case, to support a sensor there are three steps
+ you have to follow:
+ 1) define the main "sn9c102_sensor" structure by setting the basic fields;
+ 2) write a probing function to be called by the core module when the USB
+ camera is recognized, then add both the USB ids and the name of that

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

+ *
+ * History:
+ * ver 0.1 October, 2001. Initial attempt.
+ *
+ * ver 0.2 November, 2001. Fixed asbility to resize, added brightness
+ * function, made more stable (?)
+ *
+ * ver 0.21 Nov, 2001. Added gamma correction and white balance,
+ * due to Alexander Schwartz. Still trying to
+ * improve stablility. Moved stuff into stv680.h
+ *
+ * ver 0.22 Nov, 2001. Added sharpen function (by Michael Sweet,
+ * mike@easysw.com) from GIMP, also used in pencam.
+ * Simple, fast, good integer math routine.
+ *
+ * ver 0.23 Dec, 2001 (gkh)
+ * Took out sharpen function, ran code through
+ * Lindent, and did other minor tweaks to get
+ * things to work properly with 2.5.1
+ *
+ * ver 0.24 Jan, 2002 (kjs)
+ * Fixed the problem with webcam crashing after
+ * two pictures. Changed the way pic is halved to
+ * improve quality. Got rid of green line around
+ * frame. Fix brightness reset when changing size
+ * bug. Adjusted gamma filters slightly.
+ *
+ * ver 0.25 Jan, 2002 (kjs)
+ * Fixed a bug in which the driver sometimes attempted
+ * to set to a non-supported size. This allowed
+ * gnomemeeting to work.
+ * Fixed proc entry removal bug.
