Merge tag 'media/v4.8-4' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media documentation updates from Mauro Carvalho Chehab:
"This patch series does the conversion of all media documentation stuff
to Restrutured Text markup format and add them to the
Documentation/index.rst file.
The media documentation was grouped into 4 books:
- media uAPI
- media kAPI
- V4L driver-specific documentation
- DVB driver-specific documentation
It also contains several documentation improvements and one fixup
patch for a core issue with cropcap.
PS. After this patch series, the media DocBook is deprecated and
should be removed. I'll add such patch on a future pull request"

Introduction - - This is a driver for STMicroelectronics's CPiA2 (second generation -Colour Processor Interface ASIC) based cameras. This camera outputs an MJPEG -stream at up to vga size. It implements the Video4Linux interface as much as -possible. Since the V4L interface does not support compressed formats, only -an mjpeg enabled application can be used with the camera. We have modified the -gqcam application to view this stream. - - The driver is implemented as two kernel modules. The cpia2 module -contains the camera functions and the V4L interface. The cpia2_usb module -contains usb specific functions. The main reason for this was the size of the -module was getting out of hand, so I separated them. It is not likely that -there will be a parallel port version. - -FEATURES: - - Supports cameras with the Vision stv6410 (CIF) and stv6500 (VGA) cmos - sensors. I only have the vga sensor, so can't test the other. - - Image formats: VGA, QVGA, CIF, QCIF, and a number of sizes in between. - VGA and QVGA are the native image sizes for the VGA camera. CIF is done - in the coprocessor by scaling QVGA. All other sizes are done by clipping. - - Palette: YCrCb, compressed with MJPEG. - - Some compression parameters are settable. - - Sensor framerate is adjustable (up to 30 fps CIF, 15 fps VGA). - - Adjust brightness, color, contrast while streaming. - - Flicker control settable for 50 or 60 Hz mains frequency. - -2. Making and installing the stv672 driver modules: - - Requirements: - ------------- - This should work with 2.4 (2.4.23 and later) and 2.6 kernels, but has -only been tested on 2.6. Video4Linux must be either compiled into the kernel or -available as a module. Video4Linux2 is automatically detected and made -available at compile time. - - Compiling: - ---------- - As root, do a make install. This will compile and install the modules -into the media/video directory in the module tree. For 2.4 kernels, use -Makefile_2.4 (aka do make -f Makefile_2.4 install). - - Setup: - ------ - Use 'modprobe cpia2' to load and 'modprobe -r cpia2' to unload. This -may be done automatically by your distribution. - -3. Driver options - - Option Description - ------ ----------- - video_nr video device to register (0=/dev/video0, etc) - range -1 to 64. default is -1 (first available) - If you have more than 1 camera, this MUST be -1. - buffer_size Size for each frame buffer in bytes (default 68k) - num_buffers Number of frame buffers (1-32, default 3) - alternate USB Alternate (2-7, default 7) - flicker_freq Frequency for flicker reduction(50 or 60, default 60) - flicker_mode 0 to disable, or 1 to enable flicker reduction. - (default 0). This is only effective if the camera - uses a stv0672 coprocessor. - - Setting the options: - -------------------- - If you are using modules, edit /etc/modules.conf and add an options -line like this: - options cpia2 num_buffers=3 buffer_size=65535 - - If the driver is compiled into the kernel, at boot time specify them -like this: - cpia2.num_buffers=3 cpia2.buffer_size=65535 - - What buffer size should I use? - ------------------------------ - The maximum image size depends on the alternate you choose, and the -frame rate achieved by the camera. If the compression engine is able to -keep up with the frame rate, the maximum image size is given by the table -below. - The compression engine starts out at maximum compression, and will -increase image quality until it is close to the size in the table. As long -as the compression engine can keep up with the frame rate, after a short time -the images will all be about the size in the table, regardless of resolution. - At low alternate settings, the compression engine may not be able to -compress the image enough and will reduce the frame rate by producing larger -images. - The default of 68k should be good for most users. This will handle -any alternate at frame rates down to 15fps. For lower frame rates, it may -be necessary to increase the buffer size to avoid having frames dropped due -to insufficient space. - - Image size(bytes) - Alternate bytes/ms 15fps 30fps - 2 128 8533 4267 - 3 384 25600 12800 - 4 640 42667 21333 - 5 768 51200 25600 - 6 896 59733 29867 - 7 1023 68200 34100 - - How many buffers should I use? - ------------------------------ - For normal streaming, 3 should give the best results. With only 2, -it is possible for the camera to finish sending one image just after a -program has started reading the other. If this happens, the driver must drop -a frame. The exception to this is if you have a heavily loaded machine. In -this case use 2 buffers. You are probably not reading at the full frame rate. -If the camera can send multiple images before a read finishes, it could -overwrite the third buffer before the read finishes, leading to a corrupt -image. Single and double buffering have extra checks to avoid overwriting. - -4. Using the camera - - We are providing a modified gqcam application to view the output. In -order to avoid confusion, here it is called mview. There is also the qx5view -program which can also control the lights on the qx5 microscope. MJPEG Tools -(http://mjpeg.sourceforge.net) can also be used to record from the camera. - -5. Notes to developers: - - - This is a driver version stripped of the 2.4 back compatibility - and old MJPEG ioctl API. See cpia2.sf.net for 2.4 support. - -6.

VENC subdevice module - Responsible for setting outputs provided through internal DACs and also - setting timings at LCD controller port when external encoders are connected - at the port or LCD panel timings required.

This driver is a work in progress. - Its history started with the reverse-engineering effort by Björn - Danielsson <pvrusb2@dax.nu> whose web page can be found here: - - http://pvrusb2.dax.nu/ - - From there Aurelien Alleaume <slts@free.fr> began an effort to - create a video4linux compatible driver. I began with Aurelien's - last known snapshot and evolved the driver to the state it is in - here. - - More information on this driver can be found at: - - http://www.isely.net/pvrusb2.html - - - This driver has a strong separation of layers. They are very - roughly: - - 1a. Low level wire-protocol implementation with the device. - - 1b. I2C adaptor implementation and corresponding I2C client drivers - implemented elsewhere in V4L. - - 1c. High level hardware driver implementation which coordinates all - activities that ensure correct operation of the device. - - 2. A "context" layer which manages instancing of driver, setup, - tear-down, arbitration, and interaction with high level - interfaces appropriately as devices are hotplugged in the - system. - - 3. High level interfaces which glue the driver to various published - Linux APIs (V4L, sysfs, maybe DVB in the future). - - The most important shearing layer is between the top 2 layers. A - lot of work went into the driver to ensure that any kind of - conceivable API can be laid on top of the core driver. (Yes, the - driver internally leverages V4L to do its work but that really has - nothing to do with the API published by the driver to the outside - world.) The architecture allows for different APIs to - simultaneously access the driver. I have a strong sense of fairness - about APIs and also feel that it is a good design principle to keep - implementation and interface isolated from each other. Thus while - right now the V4L high level interface is the most complete, the - sysfs high level interface will work equally well for similar - functions, and there's no reason I see right now why it shouldn't be - possible to produce a DVB high level interface that can sit right - alongside V4L. - - NOTE: Complete documentation on the pvrusb2 driver is contained in - the html files within the doc directory; these are exactly the same - as what is on the web site at the time. Browse those files - (especially the FAQ) before asking questions. - - -Building - - To build these modules essentially amounts to just running "Make", - but you need the kernel source tree nearby and you will likely also - want to set a few controlling environment variables first in order - to link things up with that source tree. Please see the Makefile - here for comments that explain how to do that. - - -Source file list / functional overview: - - (Note: The term "module" used below generally refers to loosely - defined functional units within the pvrusb2 driver and bears no - relation to the Linux kernel's concept of a loadable module.) - - pvrusb2-audio.[ch] - This is glue logic that resides between this - driver and the msp3400.ko I2C client driver (which is found - elsewhere in V4L). - - pvrusb2-context.[ch] - This module implements the context for an - instance of the driver. Everything else eventually ties back to - or is otherwise instanced within the data structures implemented - here. Hotplugging is ultimately coordinated here. All high level - interfaces tie into the driver through this module. This module - helps arbitrate each interface's access to the actual driver core, - and is designed to allow concurrent access through multiple - instances of multiple interfaces (thus you can for example change - the tuner's frequency through sysfs while simultaneously streaming - video through V4L out to an instance of mplayer). - - pvrusb2-debug.h - This header defines a printk() wrapper and a mask - of debugging bit definitions for the various kinds of debug - messages that can be enabled within the driver. - - pvrusb2-debugifc.[ch] - This module implements a crude command line - oriented debug interface into the driver. Aside from being part - of the process for implementing manual firmware extraction (see - the pvrusb2 web site mentioned earlier), probably I'm the only one - who has ever used this. It is mainly a debugging aid. - - pvrusb2-eeprom.[ch] - This is glue logic that resides between this - driver the tveeprom.ko module, which is itself implemented - elsewhere in V4L. - - pvrusb2-encoder.[ch] - This module implements all protocol needed to - interact with the Conexant mpeg2 encoder chip within the pvrusb2 - device. It is a crude echo of corresponding logic in ivtv, - however the design goals (strict isolation) and physical layer - (proxy through USB instead of PCI) are enough different that this - implementation had to be completely different. - - pvrusb2-hdw-internal.h - This header defines the core data structure - in the driver used to track ALL internal state related to control - of the hardware. Nobody outside of the core hardware-handling - modules should have any business using this header. All external - access to the driver should be through one of the high level - interfaces (e.g. V4L, sysfs, etc), and in fact even those high - level interfaces are restricted to the API defined in - pvrusb2-hdw.h and NOT this header. - - pvrusb2-hdw.h - This header defines the full internal API for - controlling the hardware. High level interfaces (e.g. V4L, sysfs) - will work through here. - - pvrusb2-hdw.c - This module implements all the various bits of logic - that handle overall control of a specific pvrusb2 device. - (Policy, instantiation, and arbitration of pvrusb2 devices fall - within the jurisdiction of pvrusb-context not here). - - pvrusb2-i2c-chips-*.c - These modules implement the glue logic to - tie together and configure various I2C modules as they attach to - the I2C bus. There are two versions of this file. The "v4l2" - version is intended to be used in-tree alongside V4L, where we - implement just the logic that makes sense for a pure V4L - environment. The "all" version is intended for use outside of - V4L, where we might encounter other possibly "challenging" modules - from ivtv or older kernel snapshots (or even the support modules - in the standalone snapshot). - - pvrusb2-i2c-cmd-v4l1.[ch] - This module implements generic V4L1 - compatible commands to the I2C modules. It is here where state - changes inside the pvrusb2 driver are translated into V4L1 - commands that are in turn send to the various I2C modules. - - pvrusb2-i2c-cmd-v4l2.[ch] - This module implements generic V4L2 - compatible commands to the I2C modules. It is here where state - changes inside the pvrusb2 driver are translated into V4L2 - commands that are in turn send to the various I2C modules. - - pvrusb2-i2c-core.[ch] - This module provides an implementation of a - kernel-friendly I2C adaptor driver, through which other external - I2C client drivers (e.g. msp3400, tuner, lirc) may connect and - operate corresponding chips within the pvrusb2 device. It is - through here that other V4L modules can reach into this driver to - operate specific pieces (and those modules are in turn driven by - glue logic which is coordinated by pvrusb2-hdw, doled out by - pvrusb2-context, and then ultimately made available to users - through one of the high level interfaces). - - pvrusb2-io.[ch] - This module implements a very low level ring of - transfer buffers, required in order to stream data from the - device. This module is *very* low level. It only operates the - buffers and makes no attempt to define any policy or mechanism for - how such buffers might be used. - - pvrusb2-ioread.[ch] - This module layers on top of pvrusb2-io.[ch] - to provide a streaming API usable by a read() system call style of - I/O. Right now this is the only layer on top of pvrusb2-io.[ch], - however the underlying architecture here was intended to allow for - other styles of I/O to be implemented with additional modules, like - mmap()'ed buffers or something even more exotic. - - pvrusb2-main.c - This is the top level of the driver. Module level - and USB core entry points are here. This is our "main". - - pvrusb2-sysfs.[ch] - This is the high level interface which ties the - pvrusb2 driver into sysfs. Through this interface you can do - everything with the driver except actually stream data. - - pvrusb2-tuner.[ch] - This is glue logic that resides between this - driver and the tuner.ko I2C client driver (which is found - elsewhere in V4L). - - pvrusb2-util.h - This header defines some common macros used - throughout the driver. These macros are not really specific to - the driver, but they had to go somewhere. - - pvrusb2-v4l2.[ch] - This is the high level interface which ties the - pvrusb2 driver into video4linux. It is through here that V4L - applications can open and operate the driver in the usual V4L - ways. Note that **ALL** V4L functionality is published only - through here and nowhere else. - - pvrusb2-video-*.[ch] - This is glue logic that resides between this - driver and the saa711x.ko I2C client driver (which is found - elsewhere in V4L). Note that saa711x.ko used to be known as - saa7115.ko in ivtv. There are two versions of this; one is - selected depending on the particular saa711[5x].ko that is found. - - pvrusb2.h - This header contains compile time tunable parameters - (and at the moment the driver has very little that needs to be - tuned). - - - -Mike Isely - isely@pobox.com - diff --git a/Documentation/video4linux/README.saa7134 b/Documentation/video4linux/README.saa7134 deleted file mode 100644 index b911f0871874..000000000000 --- a/Documentation/video4linux/README.saa7134 +++ /dev/null @@ -1,82 +0,0 @@ - - -What is it? -=========== - -This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV -boards.

How do I get this damn thing to work - -Load zr36067.o. If it can't autodetect your card, use the card=X insmod -option with X being the card number as given in the previous section. -To have more than one card, use card=X1[,X2[,X3,[X4[..]]]] - -To automate this, add the following to your /etc/modprobe.d/zoran.conf: - -options zr36067 card=X1[,X2[,X3[,X4[..]]]] -alias char-major-81-0 zr36067 - -One thing to keep in mind is that this doesn't load zr36067.o itself yet. It -just automates loading. If you start using xawtv, the device won't load on -some systems, since you're trying to load modules as a user, which is not -allowed ("permission denied"). A quick workaround is to add 'Load "v4l"' to -XF86Config-4 when you use X by default, or to run 'v4l-conf -c <device>' in -one of your startup scripts (normally rc.local) if you don't use X. Both -make sure that the modules are loaded on startup, under the root account. - -=========================== - -3. What mainboard should I use (or why doesn't my card work) - -<insert lousy disclaimer here>. In short: good=SiS/Intel, bad=VIA. - -Experience tells us that people with a Buz, on average, have more problems -than users with a DC10+/LML33. Also, it tells us that people owning a VIA- -based mainboard (ktXXX, MVP3) have more problems than users with a mainboard -based on a different chipset. Here's some notes from Andrew Stevens: --- -Here's my experience of using LML33 and Buz on various motherboards: - -VIA MVP3 - Forget it. Pointless. Doesn't work. -Intel 430FX (Pentium 200) - LML33 perfect, Buz tolerable (3 or 4 frames dropped per movie) -Intel 440BX (early stepping) - LML33 tolerable. Buz starting to get annoying (6-10 frames/hour) -Intel 440BX (late stepping) - Buz tolerable, LML3 almost perfect (occasional single frame drops) -SiS735 - LML33 perfect, Buz tolerable. -VIA KT133(*) - LML33 starting to get annoying, Buz poor enough that I have up. - -Both 440BX boards were dual CPU versions. --- -Bernhard Praschinger later added: --- -AMD 751 - Buz perfect-tolerable -AMD 760 - Buz perfect-tolerable --- -In general, people on the user mailinglist won't give you much of a chance -if you have a VIA-based motherboard. They may be cheap, but sometimes, you'd -rather want to spend some more money on better boards. In general, VIA -mainboard's IDE/PCI performance will also suck badly compared to others. -You'll noticed the DC10+/DC30+ aren't mentioned anywhere in the overview. -Basically, you can assume that if the Buz works, the LML33 will work too. If -the LML33 works, the DC10+/DC30+ will work too. They're most tolerant to -different mainboard chipsets from all of the supported cards. - -If you experience timeouts during capture, buy a better mainboard or lower -the quality/buffersize during capture (see 'Concerning buffer sizes, quality, -output size etc.'). If it hangs, there's little we can do as of now. Check -your IRQs and make sure the card has its own interrupts. - -=========================== - -4. Programming interface - -This driver conforms to video4linux2. Support for V4L1 and for the custom -zoran ioctls has been removed in kernel 2.6.38. - -For programming example, please, look at lavrec.c and lavplay.c code in -the MJPEG-tools (http://mjpeg.sf.net/). - -Additional notes for software developers: - - The driver returns maxwidth and maxheight parameters according to - the current TV standard (norm). Therefore, the software which - communicates with the driver and "asks" for these parameters should - first set the correct norm. Well, it seems logically correct: TV - standard is "more constant" for current country than geometry - settings of a variety of TV capture cards which may work in ITU or - square pixel format. - -=========================== - -5. Applications - -Applications known to work with this driver: - -TV viewing: -* xawtv -* kwintv -* probably any TV application that supports video4linux or video4linux2. - -MJPEG capture/playback: -* mjpegtools/lavtools (or Linux Video Studio) -* gstreamer -* mplayer - -General raw capture: -* xawtv -* gstreamer -* probably any application that supports video4linux or video4linux2 - -Video editing: -* Cinelerra -* MainActor -* mjpegtools (or Linux Video Studio) - -=========================== - -6. Concerning buffer sizes, quality, output size etc. - -The zr36060 can do 1:2 JPEG compression. This is really the theoretical -maximum that the chipset can reach. The driver can, however, limit compression -to a maximum (size) of 1:4. The reason for this is that some cards (e.g. Buz) -can't handle 1:2 compression without stopping capture after only a few minutes. -With 1:4, it'll mostly work. If you have a Buz, use 'low_bitrate=1' to go into -1:4 max. compression mode. - -100% JPEG quality is thus 1:2 compression in practice. So for a full PAL frame -(size 720x576). The JPEG fields are stored in YUY2 format, so the size of the -fields are 720x288x16/2 bits/field (2 fields/frame) = 207360 bytes/field x 2 = -414720 bytes/frame (add some more bytes for headers and DHT (huffman)/DQT -(quantization) tables, and you'll get to something like 512kB per frame for -1:2 compression. For 1:4 compression, you'd have frames of half this size. - -Some additional explanation by Martin Samuelsson, which also explains the -importance of buffer sizes: --- -> Hmm, I do not think it is really that way. With the current (downloaded -> at 18:00 Monday) driver I get that output sizes for 10 sec: -> -q 50 -b 128 : 24.283.332 Bytes -> -q 50 -b 256 : 48.442.368 -> -q 25 -b 128 : 24.655.992 -> -q 25 -b 256 : 25.859.820 - -I woke up, and can't go to sleep again. I'll kill some time explaining why -this doesn't look strange to me. - -Let's do some math using a width of 704 pixels. I'm not sure whether the Buz -actually use that number or not, but that's not too important right now. - -704x288 pixels, one field, is 202752 pixels. Divided by 64 pixels per block; -3168 blocks per field. Each pixel consist of two bytes; 128 bytes per block; -1024 bits per block. 100% in the new driver mean 1:2 compression; the maximum -output becomes 512 bits per block. Actually 510, but 512 is simpler to use -for calculations. - -Let's say that we specify d1q50. We thus want 256 bits per block; times 3168 -becomes 811008 bits; 101376 bytes per field. We're talking raw bits and bytes -here, so we don't need to do any fancy corrections for bits-per-pixel or such -things. 101376 bytes per field. - -d1 video contains two fields per frame. Those sum up to 202752 bytes per -frame, and one of those frames goes into each buffer. - -But wait a second! -b128 gives 128kB buffers! It's not possible to cram -202752 bytes of JPEG data into 128kB! - -This is what the driver notice and automatically compensate for in your -examples. Let's do some math using this information: - -128kB is 131072 bytes. In this buffer, we want to store two fields, which -leaves 65536 bytes for each field. Using 3168 blocks per field, we get -20.68686868... available bytes per block; 165 bits. We can't allow the -request for 256 bits per block when there's only 165 bits available! The -q50 -option is silently overridden, and the -b128 option takes precedence, leaving -us with the equivalence of -q32. - -This gives us a data rate of 165 bits per block, which, times 3168, sums up -to 65340 bytes per field, out of the allowed 65536. The current driver has -another level of rate limiting; it won't accept -q values that fill more than -6/8 of the specified buffers. (I'm not sure why. "Playing it safe" seem to be -a safe bet. Personally, I think I would have lowered requested-bits-per-block -by one, or something like that.) We can't use 165 bits per block, but have to -lower it again, to 6/8 of the available buffer space: We end up with 124 bits -per block, the equivalence of -q24. With 128kB buffers, you can't use greater -than -q24 at -d1. (And PAL, and 704 pixels width...) - -The third example is limited to -q24 through the same process. The second -example, using very similar calculations, is limited to -q48. The only -example that actually grab at the specified -q value is the last one, which -is clearly visible, looking at the file size. --- - -Conclusion: the quality of the resulting movie depends on buffer size, quality, -whether or not you use 'low_bitrate=1' as insmod option for the zr36060.c -module to do 1:4 instead of 1:2 compression, etc. - -If you experience timeouts, lowering the quality/buffersize or using -'low_bitrate=1 as insmod option for zr36060.o might actually help, as is -proven by the Buz. - -=========================== - -7. It hangs/crashes/fails/whatevers! Help! - -Make sure that the card has its own interrupts (see /proc/interrupts), check -the output of dmesg at high verbosity (load zr36067.o with debug=2, -load all other modules with debug=1). Check that your mainboard is favorable -(see question 2) and if not, test the card in another computer. Also see the -notes given in question 3 and try lowering quality/buffersize/capturesize -if recording fails after a period of time. - -If all this doesn't help, give a clear description of the problem including -detailed hardware information (memory+brand, mainboard+chipset+brand, which -MJPEG card, processor, other PCI cards that might be of interest), give the -system PnP information (/proc/interrupts, /proc/dma, /proc/devices), and give -the kernel version, driver version, glibc version, gcc version and any other -information that might possibly be of interest.

Before GNT is asserted by the PCI arbiter, this -internal arbiter may still logical-or the two requests. However, once -the GNT is issued, this arbiter must lock in its decision and now route -only the granted request to the REQ pin. The arbiter decision lock -happens regardless of the state of FRAME because it does not know when -FRAME will be asserted (typically - each initiator will assert FRAME on -the cycle following GNT). When FRAME is asserted, it is the initiator s -responsibility to remove its request at the same time. It is the -arbiters responsibility to allow this request to flow through to REQ and -not allow the other request to hold REQ asserted.

When in this mode, the arbiter does not pass GNT -to the internal functions unless REQ is asserted. This prevents a bus -transaction from starting the same cycle as GNT is de-asserted. This -also has the side effect of not being able to take advantage of bus -parking, thus lowering arbitration performance.

This means it has a DMA -engine to efficiently transfer large volumes of data between the card and main -memory without requiring help from a CPU. Like most hardware, it must operate -on contiguous physical memory. This is difficult to come by in large quantities -on virtual memory machines. - -Therefore, it also supports a technique called "scatter-gather". The card can -transfer multiple buffers in one operation. Instead of allocating one large -contiguous buffer, the driver can allocate several smaller buffers. - -In practice, I've seen the average transfer to be roughly 80K, but transfers -above 128K were not uncommon, particularly at startup. The 128K figure is -important, because that is the largest block that the kernel can normally -allocate. Even still, 128K blocks are hard to come by, so the driver writer is -urged to choose a smaller block size and learn the scatter-gather technique. - -Mailbox #10 is reserved for DMA transfer information. - -Note: the hardware expects little-endian data ('intel format'). - -Flow -==== - -This section describes, in general, the order of events when handling DMA -transfers. Detailed information follows this section. - -- The card raises the Encoder interrupt. -- The driver reads the transfer type, offset and size from Mailbox #10. -- The driver constructs the scatter-gather array from enough free dma buffers - to cover the size. -- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call. -- The card raises the DMA Complete interrupt. -- The driver checks the DMA status register for any errors. -- The driver post-processes the newly transferred buffers. - -NOTE! It is possible that the Encoder and DMA Complete interrupts get raised -simultaneously. (End of the last, start of the next, etc.) - -Mailbox #10 -=========== - -The Flags, Command, Return Value and Timeout fields are ignored. - -Name: Mailbox #10 -Results[0]: Type: 0: MPEG. -Results[1]: Offset: The position relative to the card's memory space. -Results[2]: Size: The exact number of bytes to transfer. - -My speculation is that since the StartCapture API has a capture type of "RAW" -available, that the type field will have other values that correspond to YUV -and PCM data. - -Scatter-Gather Array -==================== - -The scatter-gather array is a contiguously allocated block of memory that -tells the card the source and destination of each data-block to transfer. -Card "addresses" are derived from the offset supplied by Mailbox #10. Host -addresses are the physical memory location of the target DMA buffer. - -Each S-G array element is a struct of three 32-bit words. The first word is -the source address, the second is the destination address. Both take up the -entire 32 bits. The lowest 18 bits of the third word is the transfer byte -count. The high-bit of the third word is the "last" flag. The last-flag tells -the card to raise the DMA_DONE interrupt. From hard personal experience, if -you forget to set this bit, the card will still "work" but the stream will -most likely get corrupted. - -The transfer count must be a multiple of 256. Therefore, the driver will need -to track how much data in the target buffer is valid and deal with it -accordingly. - -Array Element: - -- 32-bit Source Address -- 32-bit Destination Address -- 14-bit reserved (high bit is the last flag) -- 18-bit byte count - -DMA Transfer Status -=================== - -Register 0x0004 holds the DMA Transfer Status: - -Bit -0 read completed -1 write completed -2 DMA read error -3 DMA write error -4 Scatter-Gather array error diff --git a/Documentation/video4linux/cx2341x/fw-encoder-api.txt b/Documentation/video4linux/cx2341x/fw-encoder-api.txt deleted file mode 100644 index 5a27af2ee1c6..000000000000 --- a/Documentation/video4linux/cx2341x/fw-encoder-api.txt +++ /dev/null @@ -1,709 +0,0 @@ -Encoder firmware API description -================================ - -------------------------------------------------------------------------------- - -Name CX2341X_ENC_PING_FW -Enum 128/0x80 -Description - Does nothing.

It's also capable of capturing -data from LCD controller (FIMD) through the SoC internal writeback data -path. There are multiple FIMC instances in the SoCs (up to 4), having -slightly different capabilities, like pixel alignment constraints, rotator -availability, LCD writeback support, etc. The driver is located at -drivers/media/platform/exynos4-is directory. - -1. Supported SoCs -================= - -S5PC100 (mem-to-mem only), S5PV210, EXYNOS4210 - -2. Supported features -===================== - - - camera parallel interface capture (ITU-R.BT601/565); - - camera serial interface capture (MIPI-CSI2); - - memory-to-memory processing (color space conversion, scaling, mirror - and rotation); - - dynamic pipeline re-configuration at runtime (re-attachment of any FIMC - instance to any parallel video input or any MIPI-CSI front-end); - - runtime PM and system wide suspend/resume - -Not currently supported: - - LCD writeback input - - per frame clock gating (mem-to-mem) - -3.

User space interfaces -======================== - -4.1. Media device interface - -The driver supports Media Controller API as defined at -https://linuxtv.org/downloads/v4l-dvb-apis/media_common.html -The media device driver name is "SAMSUNG S5P FIMC". - -The purpose of this interface is to allow changing assignment of FIMC instances -to the SoC peripheral camera input at runtime and optionally to control internal -connections of the MIPI-CSIS device(s) to the FIMC entities. - -The media device interface allows to configure the SoC for capturing image -data from the sensor through more than one FIMC instance (e.g. for simultaneous -viewfinder and still capture setup). -Reconfiguration is done by enabling/disabling media links created by the driver -during initialization. The internal device topology can be easily discovered -through media entity and links enumeration. - -4.2. Memory-to-memory video node - -V4L2 memory-to-memory interface at /dev/video? device node. This is standalone -video device, it has no media pads. However please note the mem-to-mem and -capture video node operation on same FIMC instance is not allowed. The driver -detects such cases but the applications should prevent them to avoid an -undefined behaviour. - -4.3. Capture video node - -The driver supports V4L2 Video Capture Interface as defined at: -https://linuxtv.org/downloads/v4l-dvb-apis/devices.html - -At the capture and mem-to-mem video nodes only the multi-planar API is -supported. For more details see: -https://linuxtv.org/downloads/v4l-dvb-apis/planar-apis.html - -4.4. Camera capture subdevs - -Each FIMC instance exports a sub-device node (/dev/v4l-subdev?), a sub-device -node is also created per each available and enabled at the platform level -MIPI-CSI receiver device (currently up to two). - -4.5. sysfs - -In order to enable more precise camera pipeline control through the sub-device -API the driver creates a sysfs entry associated with "s5p-fimc-md" platform -device. The entry path is: /sys/platform/devices/s5p-fimc-md/subdev_conf_mode. - -In typical use case there could be a following capture pipeline configuration: -sensor subdev -> mipi-csi subdev -> fimc subdev -> video node - -When we configure these devices through sub-device API at user space, the -configuration flow must be from left to right, and the video node is -configured as last one. -When we don't use sub-device user space API the whole configuration of all -devices belonging to the pipeline is done at the video node driver. -The sysfs entry allows to instruct the capture node driver not to configure -the sub-devices (format, crop), to avoid resetting the subdevs' configuration -when the last configuration steps at the video node is performed. - -For full sub-device control support (subdevs configured at user space before -starting streaming): -# echo "sub-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode - -For V4L2 video node control only (subdevs configured internally by the host -driver): -# echo "vid-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode -This is a default option. - -5. Device mapping to video and subdev device nodes -================================================== - -There are associated two video device nodes with each device instance in -hardware - video capture and mem-to-mem and additionally a subdev node for -more precise FIMC capture subsystem control. In addition a separate v4l2 -sub-device node is created per each MIPI-CSIS device. - -How to find out which /dev/video? or /dev/v4l-subdev? is assigned to which -device? - -You can either grep through the kernel log to find relevant information, i.e. -# dmesg | grep -i fimc -(note that udev, if present, might still have rearranged the video nodes), - -or retrieve the information from /dev/media? with help of the media-ctl tool: -# media-ctl -p - -7. Build -======== - -If the driver is built as a loadable kernel module (CONFIG_VIDEO_SAMSUNG_S5P_FIMC=m) -two modules are created (in addition to the core v4l2 modules): s5p-fimc.ko and -optional s5p-csis.ko (MIPI-CSI receiver subdev). diff --git a/Documentation/video4linux/gspca.txt b/Documentation/video4linux/gspca.txt deleted file mode 100644 index d2ba80bb7af5..000000000000 --- a/Documentation/video4linux/gspca.txt +++ /dev/null @@ -1,408 +0,0 @@ -List of the webcams known by gspca. - -The modules are: - gspca_main main driver - gspca_xxxx subdriver module with xxxx as follows - -xxxx vend:prod ----- -spca501 0000:0000 MystFromOri Unknown Camera -spca508 0130:0130 Clone Digital Webcam 11043 -zc3xx 03f0:1b07 HP Premium Starter Cam -m5602 0402:5602 ALi Video Camera Controller -spca501 040a:0002 Kodak DVC-325 -spca500 040a:0300 Kodak EZ200 -zc3xx 041e:041e Creative WebCam Live! -ov519 041e:4003 Video Blaster WebCam Go Plus -spca500 041e:400a Creative PC-CAM 300 -sunplus 041e:400b Creative PC-CAM 600 -sunplus 041e:4012 PC-Cam350 -sunplus 041e:4013 Creative Pccam750 -zc3xx 041e:4017 Creative Webcam Mobile PD1090 -spca508 041e:4018 Creative Webcam Vista (PD1100) -spca561 041e:401a Creative Webcam Vista (PD1100) -zc3xx 041e:401c Creative NX -spca505 041e:401d Creative Webcam NX ULTRA -zc3xx 041e:401e Creative Nx Pro -zc3xx 041e:401f Creative Webcam Notebook PD1171 -pac207 041e:4028 Creative Webcam Vista Plus -zc3xx 041e:4029 Creative WebCam Vista Pro -zc3xx 041e:4034 Creative Instant P0620 -zc3xx 041e:4035 Creative Instant P0620D -zc3xx 041e:4036 Creative Live ! -sq930x 041e:4038 Creative Joy-IT -zc3xx 041e:403a Creative Nx Pro 2 -spca561 041e:403b Creative Webcam Vista (VF0010) -sq930x 041e:403c Creative Live!

Each of the subdevs provide a V4L2 subdev -interface to userspace. - - OMAP3 ISP CCP2 - OMAP3 ISP CSI2a - OMAP3 ISP CCDC - OMAP3 ISP preview - OMAP3 ISP resizer - OMAP3 ISP AEWB - OMAP3 ISP AF - OMAP3 ISP histogram - -Each possible link in the ISP is modelled by a link in the Media controller -interface. For an example program see [2]. - - -Controlling the OMAP 3 ISP -========================== - -In general, the settings given to the OMAP 3 ISP take effect at the beginning -of the following frame. This is done when the module becomes idle during the -vertical blanking period on the sensor. In memory-to-memory operation the pipe -is run one frame at a time. Applying the settings is done between the frames. - -All the blocks in the ISP, excluding the CSI-2 and possibly the CCP2 receiver, -insist on receiving complete frames. Sensors must thus never send the ISP -partial frames. - -Autoidle does have issues with some ISP blocks on the 3430, at least. -Autoidle is only enabled on 3630 when the omap3isp module parameter autoidle -is non-zero. - - -Events -====== - -The OMAP 3 ISP driver does support the V4L2 event interface on CCDC and -statistics (AEWB, AF and histogram) subdevs. - -The CCDC subdev produces V4L2_EVENT_FRAME_SYNC type event on HS_VS -interrupt which is used to signal frame start. Earlier version of this -driver used V4L2_EVENT_OMAP3ISP_HS_VS for this purpose. The event is -triggered exactly when the reception of the first line of the frame starts -in the CCDC module. The event can be subscribed on the CCDC subdev. - -(When using parallel interface one must pay account to correct configuration -of the VS signal polarity. This is automatically correct when using the serial -receivers.) - -Each of the statistics subdevs is able to produce events. An event is -generated whenever a statistics buffer can be dequeued by a user space -application using the VIDIOC_OMAP3ISP_STAT_REQ IOCTL. The events available -are: - - V4L2_EVENT_OMAP3ISP_AEWB - V4L2_EVENT_OMAP3ISP_AF - V4L2_EVENT_OMAP3ISP_HIST - -The type of the event data is struct omap3isp_stat_event_status for these -ioctls.

It will return -EBUSY on this -case. In order to avoid such condition, either disable/reconfigure/enable the -module or request the necessary buffer size during the first configuration -while the module is disabled. - -The internal buffer size allocation considers the requested configuration's -minimum buffer size and the value set on buf_size field. If buf_size field is -out of [minimum, maximum] buffer size range, it's clamped to fit in there. -The driver then selects the biggest value. The corrected buf_size value is -written back to user application. - -omap3isp_[h3a_af/h3a_aewb/hist]_config.config_counter: - -As the configuration doesn't take effect synchronously to the request, the -driver must provide a way to track this information to provide more accurate -data. After a configuration is requested, the config_counter returned to user -space application will be an unique value associated to that request. When -user application receives an event for buffer availability or when a new -buffer is requested, this config_counter is used to match a buffer data and a -configuration. - -VIDIOC_OMAP3ISP_STAT_REQ ------------------------- - -Send to user space the oldest data available in the internal buffer queue and -discards such buffer afterwards.

Benoit (benoits@servicepro.com) Dec 14, 1996 ----------------------------------------------------------------------------- - -Document version 1.0 - -ACKNOWLEDGMENTS ----------------- -This document was made based on 'C' code for Linux from Gideon le Grange -(legrang@active.co.za or legrang@cs.sun.ac.za) in 1994, and elaborations from -Frans Brinkman (brinkman@esd.nl) in 1996.

This document is offered in the hopes that it might help users who -want to use the RadioTrack card in an environment other than MS Windows. - -WHY THIS DOCUMENT? ------------------- -I have a RadioTrack card from back when I ran an MS-Windows platform. After -converting to Linux, I found Gideon le Grange's command-line software for -running the card, and found that it was good! Frans Brinkman made a -comfortable X-windows interface, and added a scanning feature. For hack -value, I wanted to see if the tuner could be tuned beyond the usual FM radio -broadcast band, so I could pick up the audio carriers from North American -broadcast TV channels, situated just below and above the 87.0-109.0 MHz range. -I did not get much success, but I learned about programming ioports under -Linux and gained some insights about the hardware design used for the card. - -So, without further delay, here are the details. - - -PHYSICAL DESCRIPTION --------------------- -The RadioTrack card is an ISA 8-bit FM radio card. The radio frequency (RF) -input is simply an antenna lead, and the output is a power audio signal -available through a miniature phone plug. Its RF frequencies of operation are -more or less limited from 87.0 to 109.0 MHz (the commercial FM broadcast -band). Although the registers can be programmed to request frequencies beyond -these limits, experiments did not give promising results. The variable -frequency oscillator (VFO) that demodulates the intermediate frequency (IF) -signal probably has a small range of useful frequencies, and wraps around or -gets clipped beyond the limits mentioned above. - - -CONTROLLING THE CARD WITH IOPORT --------------------------------- -The RadioTrack (base) ioport is configurable for 0x30c or 0x20c. Only one -ioport seems to be involved. The ioport decoding circuitry must be pretty -simple, as individual ioport bits are directly matched to specific functions -(or blocks) of the radio card. This way, many functions can be changed in -parallel with one write to the ioport.

Can be - parallel or serial, consists of data and control lines, e.g. clock, vertical - and horizontal synchronization signals. - -Purpose of the soc-camera subsystem ------------------------------------ - -The soc-camera subsystem initially provided a unified API between camera host -drivers and camera sensor drivers. Later the soc-camera sensor API has been -replaced with the V4L2 standard subdev API. This also made camera driver re-use -with non-soc-camera hosts possible. The camera host API to the soc-camera core -has been preserved. - -Soc-camera implements a V4L2 interface to the user, currently only the "mmap" -method is supported by host drivers. However, the soc-camera core also provides -support for the "read" method. - -The subsystem has been designed to support multiple camera host interfaces and -multiple cameras per interface, although most applications have only one camera -sensor. - -Existing drivers ----------------- - -As of 3.7 there are seven host drivers in the mainline: atmel-isi.c, -mx1_camera.c (broken, scheduled for removal), mx2_camera.c, mx3_camera.c, -omap1_camera.c, pxa_camera.c, sh_mobile_ceu_camera.c, and multiple sensor -drivers under drivers/media/i2c/soc_camera/. - -Camera host API ---------------- - -A host camera driver is registered using the - -soc_camera_host_register(struct soc_camera_host *); - -function. The host object can be initialized as follows: - - struct soc_camera_host *ici; - ici->drv_name = DRV_NAME; - ici->ops = &camera_host_ops; - ici->priv = pcdev; - ici->v4l2_dev.dev = &pdev->dev; - ici->nr = pdev->id; - -All camera host methods are passed in a struct soc_camera_host_ops: - -static struct soc_camera_host_ops camera_host_ops = { - .owner = THIS_MODULE, - .add = camera_add_device, - .remove = camera_remove_device, - .set_fmt = camera_set_fmt_cap, - .try_fmt = camera_try_fmt_cap, - .init_videobuf2 = camera_init_videobuf2, - .poll = camera_poll, - .querycap = camera_querycap, - .set_bus_param = camera_set_bus_param, - /* The rest of host operations are optional */ -}; - -.add and .remove methods are called when a sensor is attached to or detached -from the host. .set_bus_param is used to configure physical connection -parameters between the host and the sensor. .init_videobuf2 is called by -soc-camera core when a video-device is opened, the host driver would typically -call vb2_queue_init() in this method. Further video-buffer management is -implemented completely by the specific camera host driver. If the host driver -supports non-standard pixel format conversion, it should implement a -.get_formats and, possibly, a .put_formats operations. See below for more -details about format conversion. The rest of the methods are called from -respective V4L2 operations. - -Camera API ----------- - -Sensor drivers can use struct soc_camera_link, typically provided by the -platform, and used to specify to which camera host bus the sensor is connected, -and optionally provide platform .power and .reset methods for the camera. This -struct is provided to the camera driver via the I2C client device platform data -and can be obtained, using the soc_camera_i2c_to_link() macro. Care should be -taken, when using soc_camera_vdev_to_subdev() and when accessing struct -soc_camera_device, using v4l2_get_subdev_hostdata(): both only work, when -running on an soc-camera host. The actual camera driver operation is implemented -using the V4L2 subdev API. Additionally soc-camera camera drivers can use -auxiliary soc-camera helper functions like soc_camera_power_on() and -soc_camera_power_off(), which switch regulators, provided by the platform and call -board-specific power switching methods. soc_camera_apply_board_flags() takes -camera bus configuration capability flags and applies any board transformations, -e.g. signal polarity inversion. soc_mbus_get_fmtdesc() can be used to obtain a -pixel format descriptor, corresponding to a certain media-bus pixel format code. -soc_camera_limit_side() can be used to restrict beginning and length of a frame -side, based on camera capabilities. - -VIDIOC_S_CROP and VIDIOC_S_FMT behaviour ----------------------------------------- - -Above user ioctls modify image geometry as follows: - -VIDIOC_S_CROP: sets location and sizes of the sensor window. Unit is one sensor -pixel. Changing sensor window sizes preserves any scaling factors, therefore -user window sizes change as well. - -VIDIOC_S_FMT: sets user window. Should preserve previously set sensor window as -much as possible by modifying scaling factors. If the sensor window cannot be -preserved precisely, it may be changed too. - -In soc-camera there are two locations, where scaling and cropping can take -place: in the camera driver and in the host driver. User ioctls are first passed -to the host driver, which then generally passes them down to the camera driver. -It is more efficient to perform scaling and cropping in the camera driver to -save camera bus bandwidth and maximise the framerate. However, if the camera -driver failed to set the required parameters with sufficient precision, the host -driver may decide to also use its own scaling and cropping to fulfill the user's -request. - -Camera drivers are interfaced to the soc-camera core and to host drivers over -the v4l2-subdev API, which is completely functional, it doesn't pass any data. -Therefore all camera drivers shall reply to .g_fmt() requests with their current -output geometry. This is necessary to correctly configure the camera bus. -.s_fmt() and .try_fmt() have to be implemented too. Sensor window and scaling -factors have to be maintained by camera drivers internally. According to the -V4L2 API all capture drivers must support the VIDIOC_CROPCAP ioctl, hence we -rely on camera drivers implementing .cropcap(). If the camera driver does not -support cropping, it may choose to not implement .s_crop(), but to enable -cropping support by the camera host driver at least the .g_crop method must be -implemented. - -User window geometry is kept in .user_width and .user_height fields in struct -soc_camera_device and used by the soc-camera core and host drivers. The core -updates these fields upon successful completion of a .s_fmt() call, but if these -fields change elsewhere, e.g. during .s_crop() processing, the host driver is -responsible for updating them. - -Format conversion ------------------ - -V4L2 distinguishes between pixel formats, as they are stored in memory, and as -they are transferred over a media bus. Soc-camera provides support to -conveniently manage these formats. A table of standard transformations is -maintained by soc-camera core, which describes, what FOURCC pixel format will -be obtained, if a media-bus pixel format is stored in memory according to -certain rules. E.g. if MEDIA_BUS_FMT_YUYV8_2X8 data is sampled with 8 bits per -sample and stored in memory in the little-endian order with no gaps between -bytes, data in memory will represent the V4L2_PIX_FMT_YUYV FOURCC format. These -standard transformations will be used by soc-camera or by camera host drivers to -configure camera drivers to produce the FOURCC format, requested by the user, -using the VIDIOC_S_FMT ioctl(). Apart from those standard format conversions, -host drivers can also provide their own conversion rules by implementing a -.get_formats and, if required, a .put_formats methods. - --- -Author: Guennadi Liakhovetski <g.liakhovetski@gmx.de> diff --git a/Documentation/video4linux/uvcvideo.txt b/Documentation/video4linux/uvcvideo.txt deleted file mode 100644 index 35ce19cddcf8..000000000000 --- a/Documentation/video4linux/uvcvideo.txt +++ /dev/null @@ -1,239 +0,0 @@ -Linux USB Video Class (UVC) driver -================================== - -This file documents some driver-specific aspects of the UVC driver, such as -driver-specific ioctls and implementation notes. - -Questions and remarks can be sent to the Linux UVC development mailing list at -linux-uvc-devel@lists.berlios.de. - - -Extension Unit (XU) support ---------------------------- - -1. Introduction - -The UVC specification allows for vendor-specific extensions through extension -units (XUs). The Linux UVC driver supports extension unit controls (XU controls) -through two separate mechanisms: - - - through mappings of XU controls to V4L2 controls - - through a driver-specific ioctl interface - -The first one allows generic V4L2 applications to use XU controls by mapping -certain XU controls onto V4L2 controls, which then show up during ordinary -control enumeration. - -The second mechanism requires uvcvideo-specific knowledge for the application to -access XU controls but exposes the entire UVC XU concept to user space for -maximum flexibility. - -Both mechanisms complement each other and are described in more detail below. - - -2. Control mappings - -The UVC driver provides an API for user space applications to define so-called -control mappings at runtime. These allow for individual XU controls or byte -ranges thereof to be mapped to new V4L2 controls. Such controls appear and -function exactly like normal V4L2 controls (i.e. the stock controls, such as -brightness, contrast, etc.). However, reading or writing of such a V4L2 controls -triggers a read or write of the associated XU control. - -The ioctl used to create these control mappings is called UVCIOC_CTRL_MAP. -Previous driver versions (before 0.2.0) required another ioctl to be used -beforehand (UVCIOC_CTRL_ADD) to pass XU control information to the UVC driver. -This is no longer necessary as newer uvcvideo versions query the information -directly from the device. - -For details on the UVCIOC_CTRL_MAP ioctl please refer to the section titled -"IOCTL reference" below. - - -3. Driver specific XU control interface - -For applications that need to access XU controls directly, e.g. for testing -purposes, firmware upload, or accessing binary controls, a second mechanism to -access XU controls is provided in the form of a driver-specific ioctl, namely -UVCIOC_CTRL_QUERY. - -A call to this ioctl allows applications to send queries to the UVC driver that -directly map to the low-level UVC control requests. - -In order to make such a request the UVC unit ID of the control's extension unit -and the control selector need to be known. This information either needs to be -hardcoded in the application or queried using other ways such as by parsing the -UVC descriptor or, if available, using the media controller API to enumerate a -device's entities. - -Unless the control size is already known it is necessary to first make a -UVC_GET_LEN requests in order to be able to allocate a sufficiently large buffer -and set the buffer size to the correct value. Similarly, to find out whether -UVC_GET_CUR or UVC_SET_CUR are valid requests for a given control, a -UVC_GET_INFO request should be made. The bits 0 (GET supported) and 1 (SET -supported) of the resulting byte indicate which requests are valid. - -With the addition of the UVCIOC_CTRL_QUERY ioctl the UVCIOC_CTRL_GET and -UVCIOC_CTRL_SET ioctls have become obsolete since their functionality is a -subset of the former ioctl. For the time being they are still supported but -application developers are encouraged to use UVCIOC_CTRL_QUERY instead. - -For details on the UVCIOC_CTRL_QUERY ioctl please refer to the section titled -"IOCTL reference" below. - - -4.

If the subdev driver -contains controls that already exist in the V4L2 driver, then those will be -skipped (so a V4L2 driver can always override a subdev control). - -What happens here is that v4l2_device_register_subdev() calls -v4l2_ctrl_add_handler() adding the controls of the subdev to the controls -of v4l2_device. - - -Accessing Control Values -======================== - -The following union is used inside the control framework to access control -values: - -union v4l2_ctrl_ptr { - s32 *p_s32; - s64 *p_s64; - char *p_char; - void *p; -}; - -The v4l2_ctrl struct contains these fields that can be used to access both -current and new values: - - s32 val; - struct { - s32 val; - } cur; - - - union v4l2_ctrl_ptr p_new; - union v4l2_ctrl_ptr p_cur; - -If the control has a simple s32 type type, then: - - &ctrl->val == ctrl->p_new.p_s32 - &ctrl->cur.val == ctrl->p_cur.p_s32 - -For all other types use ctrl->p_cur.p<something>. Basically the val -and cur.val fields can be considered an alias since these are used so often. - -Within the control ops you can freely use these. The val and cur.val speak for -themselves. The p_char pointers point to character buffers of length -ctrl->maximum + 1, and are always 0-terminated. - -Unless the control is marked volatile the p_cur field points to the the -current cached control value. When you create a new control this value is made -identical to the default value. After calling v4l2_ctrl_handler_setup() this -value is passed to the hardware. It is generally a good idea to call this -function. - -Whenever a new value is set that new value is automatically cached. This means -that most drivers do not need to implement the g_volatile_ctrl() op. The -exception is for controls that return a volatile register such as a signal -strength read-out that changes continuously. In that case you will need to -implement g_volatile_ctrl like this: - - static int foo_g_volatile_ctrl(struct v4l2_ctrl *ctrl) - { - switch (ctrl->id) { - case V4L2_CID_BRIGHTNESS: - ctrl->val = read_reg(0x123); - break; - } - } - -Note that you use the 'new value' union as well in g_volatile_ctrl. In general -controls that need to implement g_volatile_ctrl are read-only controls. If they -are not, a V4L2_EVENT_CTRL_CH_VALUE will not be generated when the control -changes. - -To mark a control as volatile you have to set V4L2_CTRL_FLAG_VOLATILE: - - ctrl = v4l2_ctrl_new_std(&sd->ctrl_handler, ...); - if (ctrl) - ctrl->flags |= V4L2_CTRL_FLAG_VOLATILE; - -For try/s_ctrl the new values (i.e. as passed by the user) are filled in and -you can modify them in try_ctrl or set them in s_ctrl. The 'cur' union -contains the current value, which you can use (but not change!) as well. - -If s_ctrl returns 0 (OK), then the control framework will copy the new final -values to the 'cur' union. - -While in g_volatile/s/try_ctrl you can access the value of all controls owned -by the same handler since the handler's lock is held. If you need to access -the value of controls owned by other handlers, then you have to be very careful -not to introduce deadlocks. - -Outside of the control ops you have to go through to helper functions to get -or set a single control value safely in your driver: - - s32 v4l2_ctrl_g_ctrl(struct v4l2_ctrl *ctrl); - int v4l2_ctrl_s_ctrl(struct v4l2_ctrl *ctrl, s32 val); - -These functions go through the control framework just as VIDIOC_G/S_CTRL ioctls -do. Don't use these inside the control ops g_volatile/s/try_ctrl, though, that -will result in a deadlock since these helpers lock the handler as well. - -You can also take the handler lock yourself: - - mutex_lock(&state->ctrl_handler.lock); - pr_info("String value is '%s'\n", ctrl1->p_cur.p_char); - pr_info("Integer value is '%s'\n", ctrl2->cur.val); - mutex_unlock(&state->ctrl_handler.lock); - - -Menu Controls -============= - -The v4l2_ctrl struct contains this union: - - union { - u32 step; - u32 menu_skip_mask; - }; - -For menu controls menu_skip_mask is used. What it does is that it allows you -to easily exclude certain menu items. This is used in the VIDIOC_QUERYMENU -implementation where you can return -EINVAL if a certain menu item is not -present. Note that VIDIOC_QUERYCTRL always returns a step value of 1 for -menu controls. - -A good example is the MPEG Audio Layer II Bitrate menu control where the -menu is a list of standardized possible bitrates. But in practice hardware -implementations will only support a subset of those. By setting the skip -mask you can tell the framework which menu items should be skipped. Setting -it to 0 means that all menu items are supported. - -You set this mask either through the v4l2_ctrl_config struct for a custom -control, or by calling v4l2_ctrl_new_std_menu(). - - -Custom Controls -=============== - -Driver specific controls can be created using v4l2_ctrl_new_custom(): - - static const struct v4l2_ctrl_config ctrl_filter = { - .ops = &ctrl_custom_ops, - .id = V4L2_CID_MPEG_CX2341X_VIDEO_SPATIAL_FILTER, - .name = "Spatial Filter", - .type = V4L2_CTRL_TYPE_INTEGER, - .flags = V4L2_CTRL_FLAG_SLIDER, - .max = 15, - .step = 1, - }; - - ctrl = v4l2_ctrl_new_custom(&foo->ctrl_handler, &ctrl_filter, NULL); - -The last argument is the priv pointer which can be set to driver-specific -private data. - -The v4l2_ctrl_config struct also has a field to set the is_private flag. - -If the name field is not set, then the framework will assume this is a standard -control and will fill in the name, type and flags fields accordingly. - - -Active and Grabbed Controls -=========================== - -If you get more complex relationships between controls, then you may have to -activate and deactivate controls. For example, if the Chroma AGC control is -on, then the Chroma Gain control is inactive. That is, you may set it, but -the value will not be used by the hardware as long as the automatic gain -control is on. Typically user interfaces can disable such input fields. - -You can set the 'active' status using v4l2_ctrl_activate(). By default all -controls are active. Note that the framework does not check for this flag. -It is meant purely for GUIs. The function is typically called from within -s_ctrl. - -The other flag is the 'grabbed' flag. A grabbed control means that you cannot -change it because it is in use by some resource. Typical examples are MPEG -bitrate controls that cannot be changed while capturing is in progress. - -If a control is set to 'grabbed' using v4l2_ctrl_grab(), then the framework -will return -EBUSY if an attempt is made to set this control. The -v4l2_ctrl_grab() function is typically called from the driver when it -starts or stops streaming. - - -Control Clusters -================ - -By default all controls are independent from the others. But in more -complex scenarios you can get dependencies from one control to another. -In that case you need to 'cluster' them: - - struct foo { - struct v4l2_ctrl_handler ctrl_handler; -#define AUDIO_CL_VOLUME (0) -#define AUDIO_CL_MUTE (1) - struct v4l2_ctrl *audio_cluster[2]; - ... - }; - - state->audio_cluster[AUDIO_CL_VOLUME] = - v4l2_ctrl_new_std(&state->ctrl_handler, ...); - state->audio_cluster[AUDIO_CL_MUTE] = - v4l2_ctrl_new_std(&state->ctrl_handler, ...); - v4l2_ctrl_cluster(ARRAY_SIZE(state->audio_cluster), state->audio_cluster); - -From now on whenever one or more of the controls belonging to the same -cluster is set (or 'gotten', or 'tried'), only the control ops of the first -control ('volume' in this example) is called. You effectively create a new -composite control. Similar to how a 'struct' works in C. - -So when s_ctrl is called with V4L2_CID_AUDIO_VOLUME as argument, you should set -all two controls belonging to the audio_cluster: - - static int foo_s_ctrl(struct v4l2_ctrl *ctrl) - { - struct foo *state = container_of(ctrl->handler, struct foo, ctrl_handler); - - switch (ctrl->id) { - case V4L2_CID_AUDIO_VOLUME: { - struct v4l2_ctrl *mute = ctrl->cluster[AUDIO_CL_MUTE]; - - write_reg(0x123, mute->val ? 0 : ctrl->val); - break; - } - case V4L2_CID_CONTRAST: - write_reg(0x456, ctrl->val); - break; - } - return 0; - } - -In the example above the following are equivalent for the VOLUME case: - - ctrl == ctrl->cluster[AUDIO_CL_VOLUME] == state->audio_cluster[AUDIO_CL_VOLUME] - ctrl->cluster[AUDIO_CL_MUTE] == state->audio_cluster[AUDIO_CL_MUTE] - -In practice using cluster arrays like this becomes very tiresome. So instead -the following equivalent method is used: - - struct { - /* audio cluster */ - struct v4l2_ctrl *volume; - struct v4l2_ctrl *mute; - }; - -The anonymous struct is used to clearly 'cluster' these two control pointers, -but it serves no other purpose. The effect is the same as creating an -array with two control pointers. So you can just do: - - state->volume = v4l2_ctrl_new_std(&state->ctrl_handler, ...); - state->mute = v4l2_ctrl_new_std(&state->ctrl_handler, ...); - v4l2_ctrl_cluster(2, &state->volume); - -And in foo_s_ctrl you can use these pointers directly: state->mute->val. - -Note that controls in a cluster may be NULL. For example, if for some -reason mute was never added (because the hardware doesn't support that -particular feature), then mute will be NULL. So in that case we have a -cluster of 2 controls, of which only 1 is actually instantiated. The -only restriction is that the first control of the cluster must always be -present, since that is the 'master' control of the cluster. The master -control is the one that identifies the cluster and that provides the -pointer to the v4l2_ctrl_ops struct that is used for that cluster. - -Obviously, all controls in the cluster array must be initialized to either -a valid control or to NULL. - -In rare cases you might want to know which controls of a cluster actually -were set explicitly by the user. For this you can check the 'is_new' flag of -each control. For example, in the case of a volume/mute cluster the 'is_new' -flag of the mute control would be set if the user called VIDIOC_S_CTRL for -mute only. If the user would call VIDIOC_S_EXT_CTRLS for both mute and volume -controls, then the 'is_new' flag would be 1 for both controls. - -The 'is_new' flag is always 1 when called from v4l2_ctrl_handler_setup(). - - -Handling autogain/gain-type Controls with Auto Clusters -======================================================= - -A common type of control cluster is one that handles 'auto-foo/foo'-type -controls. Typical examples are autogain/gain, autoexposure/exposure, -autowhitebalance/red balance/blue balance. In all cases you have one control -that determines whether another control is handled automatically by the hardware, -or whether it is under manual control from the user. - -If the cluster is in automatic mode, then the manual controls should be -marked inactive and volatile. When the volatile controls are read the -g_volatile_ctrl operation should return the value that the hardware's automatic -mode set up automatically. - -If the cluster is put in manual mode, then the manual controls should become -active again and the volatile flag is cleared (so g_volatile_ctrl is no longer -called while in manual mode). In addition just before switching to manual mode -the current values as determined by the auto mode are copied as the new manual -values. - -Finally the V4L2_CTRL_FLAG_UPDATE should be set for the auto control since -changing that control affects the control flags of the manual controls. - -In order to simplify this a special variation of v4l2_ctrl_cluster was -introduced: - -void v4l2_ctrl_auto_cluster(unsigned ncontrols, struct v4l2_ctrl **controls, - u8 manual_val, bool set_volatile); - -The first two arguments are identical to v4l2_ctrl_cluster. The third argument -tells the framework which value switches the cluster into manual mode. The -last argument will optionally set V4L2_CTRL_FLAG_VOLATILE for the non-auto controls. -If it is false, then the manual controls are never volatile. You would typically -use that if the hardware does not give you the option to read back to values as -determined by the auto mode (e.g. if autogain is on, the hardware doesn't allow -you to obtain the current gain value). - -The first control of the cluster is assumed to be the 'auto' control. - -Using this function will ensure that you don't need to handle all the complex -flag and volatile handling. - - -VIDIOC_LOG_STATUS Support -========================= - -This ioctl allow you to dump the current status of a driver to the kernel log. -The v4l2_ctrl_handler_log_status(ctrl_handler, prefix) can be used to dump the -value of the controls owned by the given handler to the log. You can supply a -prefix as well. If the prefix didn't end with a space, then ': ' will be added -for you. - - -Different Handlers for Different Video Nodes -============================================ - -Usually the V4L2 driver has just one control handler that is global for -all video nodes. But you can also specify different control handlers for -different video nodes. You can do that by manually setting the ctrl_handler -field of struct video_device. - -That is no problem if there are no subdevs involved but if there are, then -you need to block the automatic merging of subdev controls to the global -control handler. You do that by simply setting the ctrl_handler field in -struct v4l2_device to NULL. Now v4l2_device_register_subdev() will no longer -merge subdev controls. - -After each subdev was added, you will then have to call v4l2_ctrl_add_handler -manually to add the subdev's control handler (sd->ctrl_handler) to the desired -control handler. This control handler may be specific to the video_device or -for a subset of video_device's. For example: the radio device nodes only have -audio controls, while the video and vbi device nodes share the same control -handler for the audio and video controls. - -If you want to have one handler (e.g. for a radio device node) have a subset -of another handler (e.g. for a video device node), then you should first add -the controls to the first handler, add the other controls to the second -handler and finally add the first handler to the second. For example: - - v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_VOLUME, ...); - v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...); - v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...); - v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...); - v4l2_ctrl_add_handler(&video_ctrl_handler, &radio_ctrl_handler, NULL); - -The last argument to v4l2_ctrl_add_handler() is a filter function that allows -you to filter which controls will be added. Set it to NULL if you want to add -all controls. - -Or you can add specific controls to a handler: - - volume = v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_AUDIO_VOLUME, ...); - v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_BRIGHTNESS, ...); - v4l2_ctrl_new_std(&video_ctrl_handler, &ops, V4L2_CID_CONTRAST, ...); - -What you should not do is make two identical controls for two handlers. -For example: - - v4l2_ctrl_new_std(&radio_ctrl_handler, &radio_ops, V4L2_CID_AUDIO_MUTE, ...); - v4l2_ctrl_new_std(&video_ctrl_handler, &video_ops, V4L2_CID_AUDIO_MUTE, ...); - -This would be bad since muting the radio would not change the video mute -control. The rule is to have one control for each hardware 'knob' that you -can twiddle. - - -Finding Controls -================ - -Normally you have created the controls yourself and you can store the struct -v4l2_ctrl pointer into your own struct. - -But sometimes you need to find a control from another handler that you do -not own. For example, if you have to find a volume control from a subdev. - -You can do that by calling v4l2_ctrl_find: - - struct v4l2_ctrl *volume; - - volume = v4l2_ctrl_find(sd->ctrl_handler, V4L2_CID_AUDIO_VOLUME); - -Since v4l2_ctrl_find will lock the handler you have to be careful where you -use it. For example, this is not a good idea: - - struct v4l2_ctrl_handler ctrl_handler; - - v4l2_ctrl_new_std(&ctrl_handler, &video_ops, V4L2_CID_BRIGHTNESS, ...); - v4l2_ctrl_new_std(&ctrl_handler, &video_ops, V4L2_CID_CONTRAST, ...); - -...and in video_ops.s_ctrl: - - case V4L2_CID_BRIGHTNESS: - contrast = v4l2_find_ctrl(&ctrl_handler, V4L2_CID_CONTRAST); - ... - -When s_ctrl is called by the framework the ctrl_handler.lock is already taken, so -attempting to find another control from the same handler will deadlock. - -It is recommended not to use this function from inside the control ops. - - -Inheriting Controls -=================== - -When one control handler is added to another using v4l2_ctrl_add_handler, then -by default all controls from one are merged to the other. But a subdev might -have low-level controls that make sense for some advanced embedded system, but -not when it is used in consumer-level hardware. In that case you want to keep -those low-level controls local to the subdev. You can do this by simply -setting the 'is_private' flag of the control to 1: - - static const struct v4l2_ctrl_config ctrl_private = { - .ops = &ctrl_custom_ops, - .id = V4L2_CID_..., - .name = "Some Private Control", - .type = V4L2_CTRL_TYPE_INTEGER, - .max = 15, - .step = 1, - .is_private = 1, - }; - - ctrl = v4l2_ctrl_new_custom(&foo->ctrl_handler, &ctrl_private, NULL); - -These controls will now be skipped when v4l2_ctrl_add_handler is called. - - -V4L2_CTRL_TYPE_CTRL_CLASS Controls -================================== - -Controls of this type can be used by GUIs to get the name of the control class. -A fully featured GUI can make a dialog with multiple tabs with each tab -containing the controls belonging to a particular control class. The name of -each tab can be found by querying a special control with ID <control class | 1>. - -Drivers do not have to care about this. The framework will automatically add -a control of this type whenever the first control belonging to a new control -class is added. - - -Adding Notify Callbacks -======================= - -Sometimes the platform or bridge driver needs to be notified when a control -from a sub-device driver changes. You can set a notify callback by calling -this function: - -void v4l2_ctrl_notify(struct v4l2_ctrl *ctrl, - void (*notify)(struct v4l2_ctrl *ctrl, void *priv), void *priv); - -Whenever the give control changes value the notify callback will be called -with a pointer to the control and the priv pointer that was passed with -v4l2_ctrl_notify. Note that the control's handler lock is held when the -notify function is called. - -There can be only one notify function per control handler. Any attempt -to set another notify function will cause a WARN_ON. diff --git a/Documentation/video4linux/v4l2-framework.txt b/Documentation/video4linux/v4l2-framework.txt deleted file mode 100644 index cbefc7902f5f..000000000000 --- a/Documentation/video4linux/v4l2-framework.txt +++ /dev/null @@ -1,1160 +0,0 @@ -Overview of the V4L2 driver framework -===================================== - -This text documents the various structures provided by the V4L2 framework and -their relationships. - - -Introduction ------------- - -The V4L2 drivers tend to be very complex due to the complexity of the -hardware: most devices have multiple ICs, export multiple device nodes in -/dev, and create also non-V4L2 devices such as DVB, ALSA, FB, I2C and input -(IR) devices. - -Especially the fact that V4L2 drivers have to setup supporting ICs to -do audio/video muxing/encoding/decoding makes it more complex than most. -Usually these ICs are connected to the main bridge driver through one or -more I2C busses, but other busses can also be used. Such devices are -called 'sub-devices'. - -For a long time the framework was limited to the video_device struct for -creating V4L device nodes and video_buf for handling the video buffers -(note that this document does not discuss the video_buf framework). - -This meant that all drivers had to do the setup of device instances and -connecting to sub-devices themselves. Some of this is quite complicated -to do right and many drivers never did do it correctly. - -There is also a lot of common code that could never be refactored due to -the lack of a framework. - -So this framework sets up the basic building blocks that all drivers -need and this same framework should make it much easier to refactor -common code into utility functions shared by all drivers. - -A good example to look at as a reference is the v4l2-pci-skeleton.c -source that is available in samples/v4l/. It is a skeleton driver for -a PCI capture card, and demonstrates how to use the V4L2 driver -framework. It can be used as a template for real PCI video capture driver. - -Structure of a driver ---------------------- - -All drivers have the following structure: - -1) A struct for each device instance containing the device state. - -2) A way of initializing and commanding sub-devices (if any). - -3) Creating V4L2 device nodes (/dev/videoX, /dev/vbiX and /dev/radioX) - and keeping track of device-node specific data. - -4) Filehandle-specific structs containing per-filehandle data; - -5) video buffer handling. - -This is a rough schematic of how it all relates: - - device instances - | - +-sub-device instances - | - \-V4L2 device nodes - | - \-filehandle instances - - -Structure of the framework --------------------------- - -The framework closely resembles the driver structure: it has a v4l2_device -struct for the device instance data, a v4l2_subdev struct to refer to -sub-device instances, the video_device struct stores V4L2 device node data -and the v4l2_fh struct keeps track of filehandle instances. - -The V4L2 framework also optionally integrates with the media framework. If a -driver sets the struct v4l2_device mdev field, sub-devices and video nodes -will automatically appear in the media framework as entities. - - -struct v4l2_device ------------------- - -Each device instance is represented by a struct v4l2_device (v4l2-device.h). -Very simple devices can just allocate this struct, but most of the time you -would embed this struct inside a larger struct. - -You must register the device instance: - - v4l2_device_register(struct device *dev, struct v4l2_device *v4l2_dev); - -Registration will initialize the v4l2_device struct. If the dev->driver_data -field is NULL, it will be linked to v4l2_dev. - -Drivers that want integration with the media device framework need to set -dev->driver_data manually to point to the driver-specific device structure -that embed the struct v4l2_device instance. This is achieved by a -dev_set_drvdata() call before registering the V4L2 device instance. They must -also set the struct v4l2_device mdev field to point to a properly initialized -and registered media_device instance. - -If v4l2_dev->name is empty then it will be set to a value derived from dev -(driver name followed by the bus_id, to be precise). If you set it up before -calling v4l2_device_register then it will be untouched. If dev is NULL, then -you *must* setup v4l2_dev->name before calling v4l2_device_register. - -You can use v4l2_device_set_name() to set the name based on a driver name and -a driver-global atomic_t instance. This will generate names like ivtv0, ivtv1, -etc. If the name ends with a digit, then it will insert a dash: cx18-0, -cx18-1, etc. This function returns the instance number. - -The first 'dev' argument is normally the struct device pointer of a pci_dev, -usb_interface or platform_device. It is rare for dev to be NULL, but it happens -with ISA devices or when one device creates multiple PCI devices, thus making -it impossible to associate v4l2_dev with a particular parent. - -You can also supply a notify() callback that can be called by sub-devices to -notify you of events. Whether you need to set this depends on the sub-device. -Any notifications a sub-device supports must be defined in a header in -include/media/<subdevice>.h. - -You unregister with: - - v4l2_device_unregister(struct v4l2_device *v4l2_dev); - -If the dev->driver_data field points to v4l2_dev, it will be reset to NULL. -Unregistering will also automatically unregister all subdevs from the device. - -If you have a hotpluggable device (e.g. a USB device), then when a disconnect -happens the parent device becomes invalid. Since v4l2_device has a pointer to -that parent device it has to be cleared as well to mark that the parent is -gone. To do this call: - - v4l2_device_disconnect(struct v4l2_device *v4l2_dev); - -This does *not* unregister the subdevs, so you still need to call the -v4l2_device_unregister() function for that. If your driver is not hotpluggable, -then there is no need to call v4l2_device_disconnect(). - -Sometimes you need to iterate over all devices registered by a specific -driver. This is usually the case if multiple device drivers use the same -hardware. E.g. the ivtvfb driver is a framebuffer driver that uses the ivtv -hardware. The same is true for alsa drivers for example. - -You can iterate over all registered devices as follows: - -static int callback(struct device *dev, void *p) -{ - struct v4l2_device *v4l2_dev = dev_get_drvdata(dev); - - /* test if this device was inited */ - if (v4l2_dev == NULL) - return 0; - ... - return 0; -} - -int iterate(void *p) -{ - struct device_driver *drv; - int err; - - /* Find driver 'ivtv' on the PCI bus. - pci_bus_type is a global. For USB busses use usb_bus_type. */ - drv = driver_find("ivtv", &pci_bus_type); - /* iterate over all ivtv device instances */ - err = driver_for_each_device(drv, NULL, p, callback); - put_driver(drv); - return err; -} - -Sometimes you need to keep a running counter of the device instance. This is -commonly used to map a device instance to an index of a module option array. - -The recommended approach is as follows: - -static atomic_t drv_instance = ATOMIC_INIT(0); - -static int drv_probe(struct pci_dev *pdev, const struct pci_device_id *pci_id) -{ - ... - state->instance = atomic_inc_return(&drv_instance) - 1; -} - -If you have multiple device nodes then it can be difficult to know when it is -safe to unregister v4l2_device for hotpluggable devices. For this purpose -v4l2_device has refcounting support. The refcount is increased whenever -video_register_device is called and it is decreased whenever that device node -is released. When the refcount reaches zero, then the v4l2_device release() -callback is called. You can do your final cleanup there. - -If other device nodes (e.g. ALSA) are created, then you can increase and -decrease the refcount manually as well by calling: - -void v4l2_device_get(struct v4l2_device *v4l2_dev); - -or: - -int v4l2_device_put(struct v4l2_device *v4l2_dev); - -Since the initial refcount is 1 you also need to call v4l2_device_put in the -disconnect() callback (for USB devices) or in the remove() callback (for e.g. -PCI devices), otherwise the refcount will never reach 0. - -struct v4l2_subdev ------------------- - -Many drivers need to communicate with sub-devices. These devices can do all -sort of tasks, but most commonly they handle audio and/or video muxing, -encoding or decoding. For webcams common sub-devices are sensors and camera -controllers. - -Usually these are I2C devices, but not necessarily. In order to provide the -driver with a consistent interface to these sub-devices the v4l2_subdev struct -(v4l2-subdev.h) was created. - -Each sub-device driver must have a v4l2_subdev struct. This struct can be -stand-alone for simple sub-devices or it might be embedded in a larger struct -if more state information needs to be stored. Usually there is a low-level -device struct (e.g. i2c_client) that contains the device data as setup -by the kernel. It is recommended to store that pointer in the private -data of v4l2_subdev using v4l2_set_subdevdata(). That makes it easy to go -from a v4l2_subdev to the actual low-level bus-specific device data. - -You also need a way to go from the low-level struct to v4l2_subdev. For the -common i2c_client struct the i2c_set_clientdata() call is used to store a -v4l2_subdev pointer, for other busses you may have to use other methods. - -Bridges might also need to store per-subdev private data, such as a pointer to -bridge-specific per-subdev private data. The v4l2_subdev structure provides -host private data for that purpose that can be accessed with -v4l2_get_subdev_hostdata() and v4l2_set_subdev_hostdata(). - -From the bridge driver perspective you load the sub-device module and somehow -obtain the v4l2_subdev pointer. For i2c devices this is easy: you call -i2c_get_clientdata(). For other busses something similar needs to be done. -Helper functions exists for sub-devices on an I2C bus that do most of this -tricky work for you. - -Each v4l2_subdev contains function pointers that sub-device drivers can -implement (or leave NULL if it is not applicable). Since sub-devices can do -so many different things and you do not want to end up with a huge ops struct -of which only a handful of ops are commonly implemented, the function pointers -are sorted according to category and each category has its own ops struct. - -The top-level ops struct contains pointers to the category ops structs, which -may be NULL if the subdev driver does not support anything from that category. - -It looks like this: - -struct v4l2_subdev_core_ops { - int (*log_status)(struct v4l2_subdev *sd); - int (*init)(struct v4l2_subdev *sd, u32 val); - ... -}; - -struct v4l2_subdev_tuner_ops { - ... -}; - -struct v4l2_subdev_audio_ops { - ... -}; - -struct v4l2_subdev_video_ops { - ... -}; - -struct v4l2_subdev_pad_ops { - ... -}; - -struct v4l2_subdev_ops { - const struct v4l2_subdev_core_ops *core; - const struct v4l2_subdev_tuner_ops *tuner; - const struct v4l2_subdev_audio_ops *audio; - const struct v4l2_subdev_video_ops *video; - const struct v4l2_subdev_pad_ops *video; -}; - -The core ops are common to all subdevs, the other categories are implemented -depending on the sub-device. E.g. a video device is unlikely to support the -audio ops and vice versa. - -This setup limits the number of function pointers while still making it easy -to add new ops and categories. - -A sub-device driver initializes the v4l2_subdev struct using: - - v4l2_subdev_init(sd, &ops); - -Afterwards you need to initialize subdev->name with a unique name and set the -module owner. This is done for you if you use the i2c helper functions. - -If integration with the media framework is needed, you must initialize the -media_entity struct embedded in the v4l2_subdev struct (entity field) by -calling media_entity_pads_init(), if the entity has pads: - - struct media_pad *pads = &my_sd->pads; - int err; - - err = media_entity_pads_init(&sd->entity, npads, pads); - -The pads array must have been previously initialized. There is no need to -manually set the struct media_entity function and name fields, but the -revision field must be initialized if needed. - -A reference to the entity will be automatically acquired/released when the -subdev device node (if any) is opened/closed. - -Don't forget to cleanup the media entity before the sub-device is destroyed: - - media_entity_cleanup(&sd->entity); - -If the subdev driver intends to process video and integrate with the media -framework, it must implement format related functionality using -v4l2_subdev_pad_ops instead of v4l2_subdev_video_ops. - -In that case, the subdev driver may set the link_validate field to provide -its own link validation function. The link validation function is called for -every link in the pipeline where both of the ends of the links are V4L2 -sub-devices. The driver is still responsible for validating the correctness -of the format configuration between sub-devices and video nodes. - -If link_validate op is not set, the default function -v4l2_subdev_link_validate_default() is used instead. This function ensures -that width, height and the media bus pixel code are equal on both source and -sink of the link. Subdev drivers are also free to use this function to -perform the checks mentioned above in addition to their own checks. - -There are currently two ways to register subdevices with the V4L2 core. The -first (traditional) possibility is to have subdevices registered by bridge -drivers. This can be done when the bridge driver has the complete information -about subdevices connected to it and knows exactly when to register them. This -is typically the case for internal subdevices, like video data processing units -within SoCs or complex PCI(e) boards, camera sensors in USB cameras or connected -to SoCs, which pass information about them to bridge drivers, usually in their -platform data. - -There are however also situations where subdevices have to be registered -asynchronously to bridge devices. An example of such a configuration is a Device -Tree based system where information about subdevices is made available to the -system independently from the bridge devices, e.g. when subdevices are defined -in DT as I2C device nodes. The API used in this second case is described further -below. - -Using one or the other registration method only affects the probing process, the -run-time bridge-subdevice interaction is in both cases the same. - -In the synchronous case a device (bridge) driver needs to register the -v4l2_subdev with the v4l2_device: - - int err = v4l2_device_register_subdev(v4l2_dev, sd); - -This can fail if the subdev module disappeared before it could be registered. -After this function was called successfully the subdev->dev field points to -the v4l2_device. - -If the v4l2_device parent device has a non-NULL mdev field, the sub-device -entity will be automatically registered with the media device. - -You can unregister a sub-device using: - - v4l2_device_unregister_subdev(sd); - -Afterwards the subdev module can be unloaded and sd->dev == NULL. - -You can call an ops function either directly: - - err = sd->ops->core->g_std(sd, &norm); - -but it is better and easier to use this macro: - - err = v4l2_subdev_call(sd, core, g_std, &norm); - -The macro will to the right NULL pointer checks and returns -ENODEV if subdev -is NULL, -ENOIOCTLCMD if either subdev->core or subdev->core->g_std is -NULL, or the actual result of the subdev->ops->core->g_std ops. - -It is also possible to call all or a subset of the sub-devices: - - v4l2_device_call_all(v4l2_dev, 0, core, g_std, &norm); - -Any subdev that does not support this ops is skipped and error results are -ignored. If you want to check for errors use this: - - err = v4l2_device_call_until_err(v4l2_dev, 0, core, g_std, &norm); - -Any error except -ENOIOCTLCMD will exit the loop with that error. If no -errors (except -ENOIOCTLCMD) occurred, then 0 is returned. - -The second argument to both calls is a group ID. If 0, then all subdevs are -called. If non-zero, then only those whose group ID match that value will -be called. Before a bridge driver registers a subdev it can set sd->grp_id -to whatever value it wants (it's 0 by default). This value is owned by the -bridge driver and the sub-device driver will never modify or use it. - -The group ID gives the bridge driver more control how callbacks are called. -For example, there may be multiple audio chips on a board, each capable of -changing the volume. But usually only one will actually be used when the -user want to change the volume. You can set the group ID for that subdev to -e.g. AUDIO_CONTROLLER and specify that as the group ID value when calling -v4l2_device_call_all(). That ensures that it will only go to the subdev -that needs it. - -If the sub-device needs to notify its v4l2_device parent of an event, then -it can call v4l2_subdev_notify(sd, notification, arg). This macro checks -whether there is a notify() callback defined and returns -ENODEV if not. -Otherwise the result of the notify() call is returned. - -The advantage of using v4l2_subdev is that it is a generic struct and does -not contain any knowledge about the underlying hardware. So a driver might -contain several subdevs that use an I2C bus, but also a subdev that is -controlled through GPIO pins. This distinction is only relevant when setting -up the device, but once the subdev is registered it is completely transparent. - - -In the asynchronous case subdevice probing can be invoked independently of the -bridge driver availability. The subdevice driver then has to verify whether all -the requirements for a successful probing are satisfied. This can include a -check for a master clock availability. If any of the conditions aren't satisfied -the driver might decide to return -EPROBE_DEFER to request further reprobing -attempts. Once all conditions are met the subdevice shall be registered using -the v4l2_async_register_subdev() function. Unregistration is performed using -the v4l2_async_unregister_subdev() call. Subdevices registered this way are -stored in a global list of subdevices, ready to be picked up by bridge drivers. - -Bridge drivers in turn have to register a notifier object with an array of -subdevice descriptors that the bridge device needs for its operation. This is -performed using the v4l2_async_notifier_register() call. To unregister the -notifier the driver has to call v4l2_async_notifier_unregister(). The former of -the two functions takes two arguments: a pointer to struct v4l2_device and a -pointer to struct v4l2_async_notifier. The latter contains a pointer to an array -of pointers to subdevice descriptors of type struct v4l2_async_subdev type. The -V4L2 core will then use these descriptors to match asynchronously registered -subdevices to them. If a match is detected the .bound() notifier callback is -called. After all subdevices have been located the .complete() callback is -called. When a subdevice is removed from the system the .unbind() method is -called. All three callbacks are optional. - - -V4L2 sub-device userspace API ------------------------------ - -Beside exposing a kernel API through the v4l2_subdev_ops structure, V4L2 -sub-devices can also be controlled directly by userspace applications. - -Device nodes named v4l-subdevX can be created in /dev to access sub-devices -directly. If a sub-device supports direct userspace configuration it must set -the V4L2_SUBDEV_FL_HAS_DEVNODE flag before being registered. - -After registering sub-devices, the v4l2_device driver can create device nodes -for all registered sub-devices marked with V4L2_SUBDEV_FL_HAS_DEVNODE by calling -v4l2_device_register_subdev_nodes(). Those device nodes will be automatically -removed when sub-devices are unregistered. - -The device node handles a subset of the V4L2 API. - -VIDIOC_QUERYCTRL -VIDIOC_QUERYMENU -VIDIOC_G_CTRL -VIDIOC_S_CTRL -VIDIOC_G_EXT_CTRLS -VIDIOC_S_EXT_CTRLS -VIDIOC_TRY_EXT_CTRLS - - The controls ioctls are identical to the ones defined in V4L2. They - behave identically, with the only exception that they deal only with - controls implemented in the sub-device. Depending on the driver, those - controls can be also be accessed through one (or several) V4L2 device - nodes. - -VIDIOC_DQEVENT -VIDIOC_SUBSCRIBE_EVENT -VIDIOC_UNSUBSCRIBE_EVENT - - The events ioctls are identical to the ones defined in V4L2. They - behave identically, with the only exception that they deal only with - events generated by the sub-device. Depending on the driver, those - events can also be reported by one (or several) V4L2 device nodes. - - Sub-device drivers that want to use events need to set the - V4L2_SUBDEV_USES_EVENTS v4l2_subdev::flags and initialize - v4l2_subdev::nevents to events queue depth before registering the - sub-device. After registration events can be queued as usual on the - v4l2_subdev::devnode device node. - - To properly support events, the poll() file operation is also - implemented. - -Private ioctls - - All ioctls not in the above list are passed directly to the sub-device - driver through the core::ioctl operation. - - -I2C sub-device drivers ----------------------- - -Since these drivers are so common, special helper functions are available to -ease the use of these drivers (v4l2-common.h). - -The recommended method of adding v4l2_subdev support to an I2C driver is to -embed the v4l2_subdev struct into the state struct that is created for each -I2C device instance. Very simple devices have no state struct and in that case -you can just create a v4l2_subdev directly. - -A typical state struct would look like this (where 'chipname' is replaced by -the name of the chip): - -struct chipname_state { - struct v4l2_subdev sd; - ... /* additional state fields */ -}; - -Initialize the v4l2_subdev struct as follows: - - v4l2_i2c_subdev_init(&state->sd, client, subdev_ops); - -This function will fill in all the fields of v4l2_subdev and ensure that the -v4l2_subdev and i2c_client both point to one another. - -You should also add a helper inline function to go from a v4l2_subdev pointer -to a chipname_state struct: - -static inline struct chipname_state *to_state(struct v4l2_subdev *sd) -{ - return container_of(sd, struct chipname_state, sd); -} - -Use this to go from the v4l2_subdev struct to the i2c_client struct: - - struct i2c_client *client = v4l2_get_subdevdata(sd); - -And this to go from an i2c_client to a v4l2_subdev struct: - - struct v4l2_subdev *sd = i2c_get_clientdata(client); - -Make sure to call v4l2_device_unregister_subdev(sd) when the remove() callback -is called. This will unregister the sub-device from the bridge driver. It is -safe to call this even if the sub-device was never registered. - -You need to do this because when the bridge driver destroys the i2c adapter -the remove() callbacks are called of the i2c devices on that adapter. -After that the corresponding v4l2_subdev structures are invalid, so they -have to be unregistered first. Calling v4l2_device_unregister_subdev(sd) -from the remove() callback ensures that this is always done correctly. - - -The bridge driver also has some helper functions it can use: - -struct v4l2_subdev *sd = v4l2_i2c_new_subdev(v4l2_dev, adapter, - "module_foo", "chipid", 0x36, NULL); - -This loads the given module (can be NULL if no module needs to be loaded) and -calls i2c_new_device() with the given i2c_adapter and chip/address arguments. -If all goes well, then it registers the subdev with the v4l2_device. - -You can also use the last argument of v4l2_i2c_new_subdev() to pass an array -of possible I2C addresses that it should probe. These probe addresses are -only used if the previous argument is 0. A non-zero argument means that you -know the exact i2c address so in that case no probing will take place. - -Both functions return NULL if something went wrong. - -Note that the chipid you pass to v4l2_i2c_new_subdev() is usually -the same as the module name. It allows you to specify a chip variant, e.g. -"saa7114" or "saa7115". In general though the i2c driver autodetects this. -The use of chipid is something that needs to be looked at more closely at a -later date. It differs between i2c drivers and as such can be confusing. -To see which chip variants are supported you can look in the i2c driver code -for the i2c_device_id table. This lists all the possibilities. - -There are two more helper functions: - -v4l2_i2c_new_subdev_cfg: this function adds new irq and platform_data -arguments and has both 'addr' and 'probed_addrs' arguments: if addr is not -0 then that will be used (non-probing variant), otherwise the probed_addrs -are probed. - -For example: this will probe for address 0x10: - -struct v4l2_subdev *sd = v4l2_i2c_new_subdev_cfg(v4l2_dev, adapter, - "module_foo", "chipid", 0, NULL, 0, I2C_ADDRS(0x10)); - -v4l2_i2c_new_subdev_board uses an i2c_board_info struct which is passed -to the i2c driver and replaces the irq, platform_data and addr arguments. - -If the subdev supports the s_config core ops, then that op is called with -the irq and platform_data arguments after the subdev was setup. The older -v4l2_i2c_new_(probed_)subdev functions will call s_config as well, but with -irq set to 0 and platform_data set to NULL. - -struct video_device -------------------- - -The actual device nodes in the /dev directory are created using the -video_device struct (v4l2-dev.h). This struct can either be allocated -dynamically or embedded in a larger struct. - -To allocate it dynamically use: - - struct video_device *vdev = video_device_alloc(); - - if (vdev == NULL) - return -ENOMEM; - - vdev->release = video_device_release; - -If you embed it in a larger struct, then you must set the release() -callback to your own function: - - struct video_device *vdev = &my_vdev->vdev; - - vdev->release = my_vdev_release; - -The release callback must be set and it is called when the last user -of the video device exits. - -The default video_device_release() callback just calls kfree to free the -allocated memory. - -There is also a video_device_release_empty() function that does nothing -(is empty) and can be used if the struct is embedded and there is nothing -to do when it is released. - -You should also set these fields: - -- v4l2_dev: must be set to the v4l2_device parent device. - -- name: set to something descriptive and unique. - -- vfl_dir: set this to VFL_DIR_RX for capture devices (VFL_DIR_RX has value 0, - so this is normally already the default), set to VFL_DIR_TX for output - devices and VFL_DIR_M2M for mem2mem (codec) devices. - -- fops: set to the v4l2_file_operations struct. - -- ioctl_ops: if you use the v4l2_ioctl_ops to simplify ioctl maintenance - (highly recommended to use this and it might become compulsory in the - future!), then set this to your v4l2_ioctl_ops struct. The vfl_type and - vfl_dir fields are used to disable ops that do not match the type/dir - combination. E.g. VBI ops are disabled for non-VBI nodes, and output ops - are disabled for a capture device. This makes it possible to provide - just one v4l2_ioctl_ops struct for both vbi and video nodes. - -- lock: leave to NULL if you want to do all the locking in the driver. - Otherwise you give it a pointer to a struct mutex_lock and before the - unlocked_ioctl file operation is called this lock will be taken by the - core and released afterwards. See the next section for more details. - -- queue: a pointer to the struct vb2_queue associated with this device node. - If queue is non-NULL, and queue->lock is non-NULL, then queue->lock is - used for the queuing ioctls (VIDIOC_REQBUFS, CREATE_BUFS, QBUF, DQBUF, - QUERYBUF, PREPARE_BUF, STREAMON and STREAMOFF) instead of the lock above. - That way the vb2 queuing framework does not have to wait for other ioctls. - This queue pointer is also used by the vb2 helper functions to check for - queuing ownership (i.e. is the filehandle calling it allowed to do the - operation). - -- prio: keeps track of the priorities. Used to implement VIDIOC_G/S_PRIORITY. - If left to NULL, then it will use the struct v4l2_prio_state in v4l2_device. - If you want to have a separate priority state per (group of) device node(s), - then you can point it to your own struct v4l2_prio_state. - -- dev_parent: you only set this if v4l2_device was registered with NULL as - the parent device struct. This only happens in cases where one hardware - device has multiple PCI devices that all share the same v4l2_device core. - - The cx88 driver is an example of this: one core v4l2_device struct, but - it is used by both a raw video PCI device (cx8800) and a MPEG PCI device - (cx8802). Since the v4l2_device cannot be associated with two PCI devices - at the same time it is setup without a parent device. But when the struct - video_device is initialized you *do* know which parent PCI device to use and - so you set dev_device to the correct PCI device. - -If you use v4l2_ioctl_ops, then you should set .unlocked_ioctl to video_ioctl2 -in your v4l2_file_operations struct. - -Do not use .ioctl! This is deprecated and will go away in the future. - -In some cases you want to tell the core that a function you had specified in -your v4l2_ioctl_ops should be ignored. You can mark such ioctls by calling this -function before video_device_register is called: - -void v4l2_disable_ioctl(struct video_device *vdev, unsigned int cmd); - -This tends to be needed if based on external factors (e.g. which card is -being used) you want to turns off certain features in v4l2_ioctl_ops without -having to make a new struct. - -The v4l2_file_operations struct is a subset of file_operations. The main -difference is that the inode argument is omitted since it is never used. - -If integration with the media framework is needed, you must initialize the -media_entity struct embedded in the video_device struct (entity field) by -calling media_entity_pads_init(): - - struct media_pad *pad = &my_vdev->pad; - int err; - - err = media_entity_pads_init(&vdev->entity, 1, pad); - -The pads array must have been previously initialized. There is no need to -manually set the struct media_entity type and name fields. - -A reference to the entity will be automatically acquired/released when the -video device is opened/closed. - -ioctls and locking ------------------- - -The V4L core provides optional locking services. The main service is the -lock field in struct video_device, which is a pointer to a mutex. If you set -this pointer, then that will be used by unlocked_ioctl to serialize all ioctls. - -If you are using the videobuf2 framework, then there is a second lock that you -can set: video_device->queue->lock. If set, then this lock will be used instead -of video_device->lock to serialize all queuing ioctls (see the previous section -for the full list of those ioctls). - -The advantage of using a different lock for the queuing ioctls is that for some -drivers (particularly USB drivers) certain commands such as setting controls -can take a long time, so you want to use a separate lock for the buffer queuing -ioctls. That way your VIDIOC_DQBUF doesn't stall because the driver is busy -changing the e.g. exposure of the webcam. - -Of course, you can always do all the locking yourself by leaving both lock -pointers at NULL. - -If you use the old videobuf then you must pass the video_device lock to the -videobuf queue initialize function: if videobuf has to wait for a frame to -arrive, then it will temporarily unlock the lock and relock it afterwards. If -your driver also waits in the code, then you should do the same to allow other -processes to access the device node while the first process is waiting for -something. - -In the case of videobuf2 you will need to implement the wait_prepare and -wait_finish callbacks to unlock/lock if applicable. If you use the queue->lock -pointer, then you can use the helper functions vb2_ops_wait_prepare/finish. - -The implementation of a hotplug disconnect should also take the lock from -video_device before calling v4l2_device_disconnect. If you are also using -video_device->queue->lock, then you have to first lock video_device->queue->lock -followed by video_device->lock. That way you can be sure no ioctl is running -when you call v4l2_device_disconnect. - -video_device registration -------------------------- - -Next you register the video device: this will create the character device -for you. - - err = video_register_device(vdev, VFL_TYPE_GRABBER, -1); - if (err) { - video_device_release(vdev); /* or kfree(my_vdev); */ - return err; - } - -If the v4l2_device parent device has a non-NULL mdev field, the video device -entity will be automatically registered with the media device. - -Which device is registered depends on the type argument. The following -types exist: - -VFL_TYPE_GRABBER: videoX for video input/output devices -VFL_TYPE_VBI: vbiX for vertical blank data (i.e. closed captions, teletext) -VFL_TYPE_RADIO: radioX for radio tuners -VFL_TYPE_SDR: swradioX for Software Defined Radio tuners - -The last argument gives you a certain amount of control over the device -device node number used (i.e. the X in videoX). Normally you will pass -1 -to let the v4l2 framework pick the first free number. But sometimes users -want to select a specific node number. It is common that drivers allow -the user to select a specific device node number through a driver module -option. That number is then passed to this function and video_register_device -will attempt to select that device node number. If that number was already -in use, then the next free device node number will be selected and it -will send a warning to the kernel log. - -Another use-case is if a driver creates many devices. In that case it can -be useful to place different video devices in separate ranges. For example, -video capture devices start at 0, video output devices start at 16. -So you can use the last argument to specify a minimum device node number -and the v4l2 framework will try to pick the first free number that is equal -or higher to what you passed. If that fails, then it will just pick the -first free number. - -Since in this case you do not care about a warning about not being able -to select the specified device node number, you can call the function -video_register_device_no_warn() instead. - -Whenever a device node is created some attributes are also created for you. -If you look in /sys/class/video4linux you see the devices. Go into e.g. -video0 and you will see 'name', 'dev_debug' and 'index' attributes. The 'name' -attribute is the 'name' field of the video_device struct. The 'dev_debug' attribute -can be used to enable core debugging. See the next section for more detailed -information on this. - -The 'index' attribute is the index of the device node: for each call to -video_register_device() the index is just increased by 1. The first video -device node you register always starts with index 0. - -Users can setup udev rules that utilize the index attribute to make fancy -device names (e.g. 'mpegX' for MPEG video capture device nodes). - -After the device was successfully registered, then you can use these fields: - -- vfl_type: the device type passed to video_register_device. -- minor: the assigned device minor number. -- num: the device node number (i.e. the X in videoX). -- index: the device index number. - -If the registration failed, then you need to call video_device_release() -to free the allocated video_device struct, or free your own struct if the -video_device was embedded in it. The vdev->release() callback will never -be called if the registration failed, nor should you ever attempt to -unregister the device if the registration failed. - -video device debugging ----------------------- - -The 'dev_debug' attribute that is created for each video, vbi, radio or swradio -device in /sys/class/video4linux/<devX>/ allows you to enable logging of -file operations. - -It is a bitmask and the following bits can be set: - -0x01: Log the ioctl name and error code. VIDIOC_(D)QBUF ioctls are only logged - if bit 0x08 is also set. -0x02: Log the ioctl name arguments and error code. VIDIOC_(D)QBUF ioctls are - only logged if bit 0x08 is also set. -0x04: Log the file operations open, release, read, write, mmap and - get_unmapped_area. The read and write operations are only logged if - bit 0x08 is also set. -0x08: Log the read and write file operations and the VIDIOC_QBUF and - VIDIOC_DQBUF ioctls. -0x10: Log the poll file operation. - -video_device cleanup --------------------- - -When the video device nodes have to be removed, either during the unload -of the driver or because the USB device was disconnected, then you should -unregister them: - - video_unregister_device(vdev); - -This will remove the device nodes from sysfs (causing udev to remove them -from /dev). - -After video_unregister_device() returns no new opens can be done. However, -in the case of USB devices some application might still have one of these -device nodes open. So after the unregister all file operations (except -release, of course) will return an error as well. - -When the last user of the video device node exits, then the vdev->release() -callback is called and you can do the final cleanup there. - -Don't forget to cleanup the media entity associated with the video device if -it has been initialized: - - media_entity_cleanup(&vdev->entity); - -This can be done from the release callback. - - -video_device helper functions ------------------------------ - -There are a few useful helper functions: - -- file/video_device private data - -You can set/get driver private data in the video_device struct using: - -void *video_get_drvdata(struct video_device *vdev); -void video_set_drvdata(struct video_device *vdev, void *data); - -Note that you can safely call video_set_drvdata() before calling -video_register_device(). - -And this function: - -struct video_device *video_devdata(struct file *file); - -returns the video_device belonging to the file struct. - -The video_drvdata function combines video_get_drvdata with video_devdata: - -void *video_drvdata(struct file *file); - -You can go from a video_device struct to the v4l2_device struct using: - -struct v4l2_device *v4l2_dev = vdev->v4l2_dev; - -- Device node name - -The video_device node kernel name can be retrieved using - -const char *video_device_node_name(struct video_device *vdev); - -The name is used as a hint by userspace tools such as udev. The function -should be used where possible instead of accessing the video_device::num and -video_device::minor fields. - - -video buffer helper functions ------------------------------ - -The v4l2 core API provides a set of standard methods (called "videobuf") -for dealing with video buffers. Those methods allow a driver to implement -read(), mmap() and overlay() in a consistent way. There are currently -methods for using video buffers on devices that supports DMA with -scatter/gather method (videobuf-dma-sg), DMA with linear access -(videobuf-dma-contig), and vmalloced buffers, mostly used on USB drivers -(videobuf-vmalloc). - -Please see Documentation/video4linux/videobuf for more information on how -to use the videobuf layer. - -struct v4l2_fh --------------- - -struct v4l2_fh provides a way to easily keep file handle specific data -that is used by the V4L2 framework. New drivers must use struct v4l2_fh -since it is also used to implement priority handling (VIDIOC_G/S_PRIORITY). - -The users of v4l2_fh (in the V4L2 framework, not the driver) know -whether a driver uses v4l2_fh as its file->private_data pointer by -testing the V4L2_FL_USES_V4L2_FH bit in video_device->flags. This bit is -set whenever v4l2_fh_init() is called. - -struct v4l2_fh is allocated as a part of the driver's own file handle -structure and file->private_data is set to it in the driver's open -function by the driver. - -In many cases the struct v4l2_fh will be embedded in a larger structure. -In that case you should call v4l2_fh_init+v4l2_fh_add in open() and -v4l2_fh_del+v4l2_fh_exit in release(). - -Drivers can extract their own file handle structure by using the container_of -macro. Example: - -struct my_fh { - int blah; - struct v4l2_fh fh; -}; - -... - -int my_open(struct file *file) -{ - struct my_fh *my_fh; - struct video_device *vfd; - int ret; - - ... - - my_fh = kzalloc(sizeof(*my_fh), GFP_KERNEL); - - ... - - v4l2_fh_init(&my_fh->fh, vfd); - - ... - - file->private_data = &my_fh->fh; - v4l2_fh_add(&my_fh->fh); - return 0; -} - -int my_release(struct file *file) -{ - struct v4l2_fh *fh = file->private_data; - struct my_fh *my_fh = container_of(fh, struct my_fh, fh); - - ... - v4l2_fh_del(&my_fh->fh); - v4l2_fh_exit(&my_fh->fh); - kfree(my_fh); - return 0; -} - -Below is a short description of the v4l2_fh functions used: - -void v4l2_fh_init(struct v4l2_fh *fh, struct video_device *vdev) - - Initialise the file handle. This *MUST* be performed in the driver's - v4l2_file_operations->open() handler. - -void v4l2_fh_add(struct v4l2_fh *fh) - - Add a v4l2_fh to video_device file handle list. Must be called once the - file handle is completely initialized. - -void v4l2_fh_del(struct v4l2_fh *fh) - - Unassociate the file handle from video_device(). The file handle - exit function may now be called. - -void v4l2_fh_exit(struct v4l2_fh *fh) - - Uninitialise the file handle. After uninitialisation the v4l2_fh - memory can be freed. - - -If struct v4l2_fh is not embedded, then you can use these helper functions: - -int v4l2_fh_open(struct file *filp) - - This allocates a struct v4l2_fh, initializes it and adds it to the struct - video_device associated with the file struct. - -int v4l2_fh_release(struct file *filp) - - This deletes it from the struct video_device associated with the file - struct, uninitialised the v4l2_fh and frees it. - -These two functions can be plugged into the v4l2_file_operation's open() and -release() ops. - - -Several drivers need to do something when the first file handle is opened and -when the last file handle closes. Two helper functions were added to check -whether the v4l2_fh struct is the only open filehandle of the associated -device node: - -int v4l2_fh_is_singular(struct v4l2_fh *fh) - - Returns 1 if the file handle is the only open file handle, else 0. - -int v4l2_fh_is_singular_file(struct file *filp) - - Same, but it calls v4l2_fh_is_singular with filp->private_data. - - -V4L2 events ------------ - -The V4L2 events provide a generic way to pass events to user space. -The driver must use v4l2_fh to be able to support V4L2 events. - -Events are defined by a type and an optional ID. The ID may refer to a V4L2 -object such as a control ID. If unused, then the ID is 0. - -When the user subscribes to an event the driver will allocate a number of -kevent structs for that event. So every (type, ID) event tuple will have -its own set of kevent structs. This guarantees that if a driver is generating -lots of events of one type in a short time, then that will not overwrite -events of another type. - -But if you get more events of one type than the number of kevents that were -reserved, then the oldest event will be dropped and the new one added. - -Furthermore, the internal struct v4l2_subscribed_event has merge() and -replace() callbacks which drivers can set. These callbacks are called when -a new event is raised and there is no more room. The replace() callback -allows you to replace the payload of the old event with that of the new event, -merging any relevant data from the old payload into the new payload that -replaces it. It is called when this event type has only one kevent struct -allocated. The merge() callback allows you to merge the oldest event payload -into that of the second-oldest event payload. It is called when there are two -or more kevent structs allocated. - -This way no status information is lost, just the intermediate steps leading -up to that state. - -A good example of these replace/merge callbacks is in v4l2-event.c: -ctrls_replace() and ctrls_merge() callbacks for the control event. - -Note: these callbacks can be called from interrupt context, so they must be -fast. - -Useful functions: - -void v4l2_event_queue(struct video_device *vdev, const struct v4l2_event *ev) - - Queue events to video device. The driver's only responsibility is to fill - in the type and the data fields. The other fields will be filled in by - V4L2. - -int v4l2_event_subscribe(struct v4l2_fh *fh, - struct v4l2_event_subscription *sub, unsigned elems, - const struct v4l2_subscribed_event_ops *ops) - - The video_device->ioctl_ops->vidioc_subscribe_event must check the driver - is able to produce events with specified event id. Then it calls - v4l2_event_subscribe() to subscribe the event. - - The elems argument is the size of the event queue for this event. If it is 0, - then the framework will fill in a default value (this depends on the event - type). - - The ops argument allows the driver to specify a number of callbacks: - * add: called when a new listener gets added (subscribing to the same - event twice will only cause this callback to get called once) - * del: called when a listener stops listening - * replace: replace event 'old' with event 'new'. - * merge: merge event 'old' into event 'new'. - All 4 callbacks are optional, if you don't want to specify any callbacks - the ops argument itself maybe NULL. - -int v4l2_event_unsubscribe(struct v4l2_fh *fh, - struct v4l2_event_subscription *sub) - - vidioc_unsubscribe_event in struct v4l2_ioctl_ops. A driver may use - v4l2_event_unsubscribe() directly unless it wants to be involved in - unsubscription process. - - The special type V4L2_EVENT_ALL may be used to unsubscribe all events. The - drivers may want to handle this in a special way. - -int v4l2_event_pending(struct v4l2_fh *fh) - - Returns the number of pending events. Useful when implementing poll. - -Events are delivered to user space through the poll system call. The driver -can use v4l2_fh->wait (a wait_queue_head_t) as the argument for poll_wait(). - -There are standard and private events. New standard events must use the -smallest available event type. The drivers must allocate their events from -their own class starting from class base. Class base is -V4L2_EVENT_PRIVATE_START + n * 1000 where n is the lowest available number. -The first event type in the class is reserved for future use, so the first -available event type is 'class base + 1'. - -An example on how the V4L2 events may be used can be found in the OMAP -3 ISP driver (drivers/media/platform/omap3isp). - -A subdev can directly send an event to the v4l2_device notify function with -V4L2_DEVICE_NOTIFY_EVENT. This allows the bridge to map the subdev that sends -the event to the video node(s) associated with the subdev that need to be -informed about such an event. - -V4L2 clocks ------------ - -Many subdevices, like camera sensors, TV decoders and encoders, need a clock -signal to be supplied by the system. Often this clock is supplied by the -respective bridge device. The Linux kernel provides a Common Clock Framework for -this purpose. However, it is not (yet) available on all architectures. Besides, -the nature of the multi-functional (clock, data + synchronisation, I2C control) -connection of subdevices to the system might impose special requirements on the -clock API usage. E.g. V4L2 has to support clock provider driver unregistration -while a subdevice driver is holding a reference to the clock. For these reasons -a V4L2 clock helper API has been developed and is provided to bridge and -subdevice drivers. - -The API consists of two parts: two functions to register and unregister a V4L2 -clock source: v4l2_clk_register() and v4l2_clk_unregister() and calls to control -a clock object, similar to the respective generic clock API calls: -v4l2_clk_get(), v4l2_clk_put(), v4l2_clk_enable(), v4l2_clk_disable(), -v4l2_clk_get_rate(), and v4l2_clk_set_rate(). Clock suppliers have to provide -clock operations that will be called when clock users invoke respective API -methods. - -It is expected that once the CCF becomes available on all relevant -architectures this API will be removed. diff --git a/Documentation/video4linux/videobuf b/Documentation/video4linux/videobuf deleted file mode 100644 index 3ffe9e960b6f..000000000000 --- a/Documentation/video4linux/videobuf +++ /dev/null @@ -1,355 +0,0 @@ -An introduction to the videobuf layer -Jonathan Corbet <corbet@lwn.net> -Current as of 2.6.33 - -The videobuf layer functions as a sort of glue layer between a V4L2 driver -and user space. It handles the allocation and management of buffers for -the storage of video frames. There is a set of functions which can be used -to implement many of the standard POSIX I/O system calls, including read(), -poll(), and, happily, mmap(). Another set of functions can be used to -implement the bulk of the V4L2 ioctl() calls related to streaming I/O, -including buffer allocation, queueing and dequeueing, and streaming -control. Using videobuf imposes a few design decisions on the driver -author, but the payback comes in the form of reduced code in the driver and -a consistent implementation of the V4L2 user-space API. - -Buffer types - -Not all video devices use the same kind of buffers. In fact, there are (at -least) three common variations: - - - Buffers which are scattered in both the physical and (kernel) virtual - address spaces. (Almost) all user-space buffers are like this, but it - makes great sense to allocate kernel-space buffers this way as well when - it is possible. Unfortunately, it is not always possible; working with - this kind of buffer normally requires hardware which can do - scatter/gather DMA operations. - - - Buffers which are physically scattered, but which are virtually - contiguous; buffers allocated with vmalloc(), in other words. These - buffers are just as hard to use for DMA operations, but they can be - useful in situations where DMA is not available but virtually-contiguous - buffers are convenient. - - - Buffers which are physically contiguous. Allocation of this kind of - buffer can be unreliable on fragmented systems, but simpler DMA - controllers cannot deal with anything else. - -Videobuf can work with all three types of buffers, but the driver author -must pick one at the outset and design the driver around that decision. - -[It's worth noting that there's a fourth kind of buffer: "overlay" buffers -which are located within the system's video memory. The overlay -functionality is considered to be deprecated for most use, but it still -shows up occasionally in system-on-chip drivers where the performance -benefits merit the use of this technique. Overlay buffers can be handled -as a form of scattered buffer, but there are very few implementations in -the kernel and a description of this technique is currently beyond the -scope of this document.] - -Data structures, callbacks, and initialization - -Depending on which type of buffers are being used, the driver should -include one of the following files: - - <media/videobuf-dma-sg.h> /* Physically scattered */ - <media/videobuf-vmalloc.h> /* vmalloc() buffers */ - <media/videobuf-dma-contig.h> /* Physically contiguous */ - -The driver's data structure describing a V4L2 device should include a -struct videobuf_queue instance for the management of the buffer queue, -along with a list_head for the queue of available buffers. There will also -need to be an interrupt-safe spinlock which is used to protect (at least) -the queue. - -The next step is to write four simple callbacks to help videobuf deal with -the management of buffers: - - struct videobuf_queue_ops { - int (*buf_setup)(struct videobuf_queue *q, - unsigned int *count, unsigned int *size); - int (*buf_prepare)(struct videobuf_queue *q, - struct videobuf_buffer *vb, - enum v4l2_field field); - void (*buf_queue)(struct videobuf_queue *q, - struct videobuf_buffer *vb); - void (*buf_release)(struct videobuf_queue *q, - struct videobuf_buffer *vb); - }; - -buf_setup() is called early in the I/O process, when streaming is being -initiated; its purpose is to tell videobuf about the I/O stream. The count -parameter will be a suggested number of buffers to use; the driver should -check it for rationality and adjust it if need be. As a practical rule, a -minimum of two buffers are needed for proper streaming, and there is -usually a maximum (which cannot exceed 32) which makes sense for each -device. The size parameter should be set to the expected (maximum) size -for each frame of data. - -Each buffer (in the form of a struct videobuf_buffer pointer) will be -passed to buf_prepare(), which should set the buffer's size, width, height, -and field fields properly. If the buffer's state field is -VIDEOBUF_NEEDS_INIT, the driver should pass it to: - - int videobuf_iolock(struct videobuf_queue* q, struct videobuf_buffer *vb, - struct v4l2_framebuffer *fbuf); - -Among other things, this call will usually allocate memory for the buffer. -Finally, the buf_prepare() function should set the buffer's state to -VIDEOBUF_PREPARED. - -When a buffer is queued for I/O, it is passed to buf_queue(), which should -put it onto the driver's list of available buffers and set its state to -VIDEOBUF_QUEUED. Note that this function is called with the queue spinlock -held; if it tries to acquire it as well things will come to a screeching -halt. Yes, this is the voice of experience. Note also that videobuf may -wait on the first buffer in the queue; placing other buffers in front of it -could again gum up the works. So use list_add_tail() to enqueue buffers. - -Finally, buf_release() is called when a buffer is no longer intended to be -used. The driver should ensure that there is no I/O active on the buffer, -then pass it to the appropriate free routine(s): - - /* Scatter/gather drivers */ - int videobuf_dma_unmap(struct videobuf_queue *q, - struct videobuf_dmabuf *dma); - int videobuf_dma_free(struct videobuf_dmabuf *dma); - - /* vmalloc drivers */ - void videobuf_vmalloc_free (struct videobuf_buffer *buf); - - /* Contiguous drivers */ - void videobuf_dma_contig_free(struct videobuf_queue *q, - struct videobuf_buffer *buf); - -One way to ensure that a buffer is no longer under I/O is to pass it to: - - int videobuf_waiton(struct videobuf_buffer *vb, int non_blocking, int intr); - -Here, vb is the buffer, non_blocking indicates whether non-blocking I/O -should be used (it should be zero in the buf_release() case), and intr -controls whether an interruptible wait is used. - -File operations - -At this point, much of the work is done; much of the rest is slipping -videobuf calls into the implementation of the other driver callbacks. The -first step is in the open() function, which must initialize the -videobuf queue. The function to use depends on the type of buffer used: - - void videobuf_queue_sg_init(struct videobuf_queue *q, - struct videobuf_queue_ops *ops, - struct device *dev, - spinlock_t *irqlock, - enum v4l2_buf_type type, - enum v4l2_field field, - unsigned int msize, - void *priv); - - void videobuf_queue_vmalloc_init(struct videobuf_queue *q, - struct videobuf_queue_ops *ops, - struct device *dev, - spinlock_t *irqlock, - enum v4l2_buf_type type, - enum v4l2_field field, - unsigned int msize, - void *priv); - - void videobuf_queue_dma_contig_init(struct videobuf_queue *q, - struct videobuf_queue_ops *ops, - struct device *dev, - spinlock_t *irqlock, - enum v4l2_buf_type type, - enum v4l2_field field, - unsigned int msize, - void *priv); - -In each case, the parameters are the same: q is the queue structure for the -device, ops is the set of callbacks as described above, dev is the device -structure for this video device, irqlock is an interrupt-safe spinlock to -protect access to the data structures, type is the buffer type used by the -device (cameras will use V4L2_BUF_TYPE_VIDEO_CAPTURE, for example), field -describes which field is being captured (often V4L2_FIELD_NONE for -progressive devices), msize is the size of any containing structure used -around struct videobuf_buffer, and priv is a private data pointer which -shows up in the priv_data field of struct videobuf_queue. Note that these -are void functions which, evidently, are immune to failure. - -V4L2 capture drivers can be written to support either of two APIs: the -read() system call and the rather more complicated streaming mechanism. As -a general rule, it is necessary to support both to ensure that all -applications have a chance of working with the device. Videobuf makes it -easy to do that with the same code. To implement read(), the driver need -only make a call to one of: - - ssize_t videobuf_read_one(struct videobuf_queue *q, - char __user *data, size_t count, - loff_t *ppos, int nonblocking); - - ssize_t videobuf_read_stream(struct videobuf_queue *q, - char __user *data, size_t count, - loff_t *ppos, int vbihack, int nonblocking); - -Either one of these functions will read frame data into data, returning the -amount actually read; the difference is that videobuf_read_one() will only -read a single frame, while videobuf_read_stream() will read multiple frames -if they are needed to satisfy the count requested by the application. A -typical driver read() implementation will start the capture engine, call -one of the above functions, then stop the engine before returning (though a -smarter implementation might leave the engine running for a little while in -anticipation of another read() call happening in the near future). - -The poll() function can usually be implemented with a direct call to: - - unsigned int videobuf_poll_stream(struct file *file, - struct videobuf_queue *q, - poll_table *wait); - -Note that the actual wait queue eventually used will be the one associated -with the first available buffer. - -When streaming I/O is done to kernel-space buffers, the driver must support -the mmap() system call to enable user space to access the data. In many -V4L2 drivers, the often-complex mmap() implementation simplifies to a -single call to: - - int videobuf_mmap_mapper(struct videobuf_queue *q, - struct vm_area_struct *vma); - -Everything else is handled by the videobuf code. - -The release() function requires two separate videobuf calls: - - void videobuf_stop(struct videobuf_queue *q); - int videobuf_mmap_free(struct videobuf_queue *q); - -The call to videobuf_stop() terminates any I/O in progress - though it is -still up to the driver to stop the capture engine. The call to -videobuf_mmap_free() will ensure that all buffers have been unmapped; if -so, they will all be passed to the buf_release() callback. If buffers -remain mapped, videobuf_mmap_free() returns an error code instead. The -purpose is clearly to cause the closing of the file descriptor to fail if -buffers are still mapped, but every driver in the 2.6.32 kernel cheerfully -ignores its return value. - -ioctl() operations - -The V4L2 API includes a very long list of driver callbacks to respond to -the many ioctl() commands made available to user space. A number of these -- those associated with streaming I/O - turn almost directly into videobuf -calls. The relevant helper functions are: - - int videobuf_reqbufs(struct videobuf_queue *q, - struct v4l2_requestbuffers *req); - int videobuf_querybuf(struct videobuf_queue *q, struct v4l2_buffer *b); - int videobuf_qbuf(struct videobuf_queue *q, struct v4l2_buffer *b); - int videobuf_dqbuf(struct videobuf_queue *q, struct v4l2_buffer *b, - int nonblocking); - int videobuf_streamon(struct videobuf_queue *q); - int videobuf_streamoff(struct videobuf_queue *q); - -So, for example, a VIDIOC_REQBUFS call turns into a call to the driver's -vidioc_reqbufs() callback which, in turn, usually only needs to locate the -proper struct videobuf_queue pointer and pass it to videobuf_reqbufs(). -These support functions can replace a great deal of buffer management -boilerplate in a lot of V4L2 drivers. - -The vidioc_streamon() and vidioc_streamoff() functions will be a bit more -complex, of course, since they will also need to deal with starting and -stopping the capture engine. - -Buffer allocation - -Thus far, we have talked about buffers, but have not looked at how they are -allocated. The scatter/gather case is the most complex on this front. For -allocation, the driver can leave buffer allocation entirely up to the -videobuf layer; in this case, buffers will be allocated as anonymous -user-space pages and will be very scattered indeed. If the application is -using user-space buffers, no allocation is needed; the videobuf layer will -take care of calling get_user_pages() and filling in the scatterlist array. - -If the driver needs to do its own memory allocation, it should be done in -the vidioc_reqbufs() function, *after* calling videobuf_reqbufs(). The -first step is a call to: - - struct videobuf_dmabuf *videobuf_to_dma(struct videobuf_buffer *buf); - -The returned videobuf_dmabuf structure (defined in -<media/videobuf-dma-sg.h>) includes a couple of relevant fields: - - struct scatterlist *sglist; - int sglen; - -The driver must allocate an appropriately-sized scatterlist array and -populate it with pointers to the pieces of the allocated buffer; sglen -should be set to the length of the array. - -Drivers using the vmalloc() method need not (and cannot) concern themselves -with buffer allocation at all; videobuf will handle those details. The -same is normally true of contiguous-DMA drivers as well; videobuf will -allocate the buffers (with dma_alloc_coherent()) when it sees fit. That -means that these drivers may be trying to do high-order allocations at any -time, an operation which is not always guaranteed to work. Some drivers -play tricks by allocating DMA space at system boot time; videobuf does not -currently play well with those drivers. - -As of 2.6.31, contiguous-DMA drivers can work with a user-supplied buffer, -as long as that buffer is physically contiguous. Normal user-space -allocations will not meet that criterion, but buffers obtained from other -kernel drivers, or those contained within huge pages, will work with these -drivers. - -Filling the buffers - -The final part of a videobuf implementation has no direct callback - it's -the portion of the code which actually puts frame data into the buffers, -usually in response to interrupts from the device. For all types of -drivers, this process works approximately as follows: - - - Obtain the next available buffer and make sure that somebody is actually - waiting for it. - - - Get a pointer to the memory and put video data there. - - - Mark the buffer as done and wake up the process waiting for it. - -Step (1) above is done by looking at the driver-managed list_head structure -- the one which is filled in the buf_queue() callback. Because starting -the engine and enqueueing buffers are done in separate steps, it's possible -for the engine to be running without any buffers available - in the -vmalloc() case especially. So the driver should be prepared for the list -to be empty. It is equally possible that nobody is yet interested in the -buffer; the driver should not remove it from the list or fill it until a -process is waiting on it. That test can be done by examining the buffer's -done field (a wait_queue_head_t structure) with waitqueue_active(). - -A buffer's state should be set to VIDEOBUF_ACTIVE before being mapped for -DMA; that ensures that the videobuf layer will not try to do anything with -it while the device is transferring data. - -For scatter/gather drivers, the needed memory pointers will be found in the -scatterlist structure described above. Drivers using the vmalloc() method -can get a memory pointer with: - - void *videobuf_to_vmalloc(struct videobuf_buffer *buf); - -For contiguous DMA drivers, the function to use is: - - dma_addr_t videobuf_to_dma_contig(struct videobuf_buffer *buf); - -The contiguous DMA API goes out of its way to hide the kernel-space address -of the DMA buffer from drivers. - -The final step is to set the size field of the relevant videobuf_buffer -structure to the actual size of the captured image, set state to -VIDEOBUF_DONE, then call wake_up() on the done queue. At this point, the -buffer is owned by the videobuf layer and the driver should not touch it -again. - -Developers who are interested in more information can go into the relevant -header files; there are a few low-level functions declared there which have -not been talked about here. Also worthwhile is the vivi driver -(drivers/media/platform/vivi.c), which is maintained as an example of how V4L2 -drivers should be written. Vivi only uses the vmalloc() API, but it's good -enough to get started with. Note also that all of these calls are exported -GPL-only, so they will not be available to non-GPL kernel modules. diff --git a/Documentation/video4linux/vivid.txt b/Documentation/video4linux/vivid.txt deleted file mode 100644 index 1b26519c6ddc..000000000000 --- a/Documentation/video4linux/vivid.txt +++ /dev/null @@ -1,1161 +0,0 @@ -vivid: Virtual Video Test Driver -================================ - -This driver emulates video4linux hardware of various types: video capture, video -output, vbi capture and output, radio receivers and transmitters and a software -defined radio receiver.

The default is 0x1d3d. - Each value is a bitmask with the following meaning: - bit 0: Video Capture node - bit 2-3: VBI Capture node: 0 = none, 1 = raw vbi, 2 = sliced vbi, 3 = both - bit 4: Radio Receiver node - bit 5: Software Defined Radio Receiver node - bit 8: Video Output node - bit 10-11: VBI Output node: 0 = none, 1 = raw vbi, 2 = sliced vbi, 3 = both - bit 12: Radio Transmitter node - bit 16: Framebuffer for testing overlays - - So to create four instances, the first two with just one video capture - device, the second two with just one video output device you would pass - these module options to vivid: - - n_devs=4 node_types=0x1,0x1,0x100,0x100 - -num_inputs: the number of inputs, one for each instance. By default 4 inputs - are created for each video capture device. At most 16 inputs can be created, - and there must be at least one. - -input_types: the input types for each instance, the default is 0xe4. This defines - what the type of each input is when the inputs are created for each driver - instance. This is a hexadecimal value with up to 16 pairs of bits, each - pair gives the type and bits 0-1 map to input 0, bits 2-3 map to input 1, - 30-31 map to input 15. Each pair of bits has the following meaning: - - 00: this is a webcam input - 01: this is a TV tuner input - 10: this is an S-Video input - 11: this is an HDMI input - - So to create a video capture device with 8 inputs where input 0 is a TV - tuner, inputs 1-3 are S-Video inputs and inputs 4-7 are HDMI inputs you - would use the following module options: - - num_inputs=8 input_types=0xffa9 - -num_outputs: the number of outputs, one for each instance. By default 2 outputs - are created for each video output device. At most 16 outputs can be - created, and there must be at least one. - -output_types: the output types for each instance, the default is 0x02. This defines - what the type of each output is when the outputs are created for each - driver instance. This is a hexadecimal value with up to 16 bits, each bit - gives the type and bit 0 maps to output 0, bit 1 maps to output 1, bit - 15 maps to output 15. The meaning of each bit is as follows: - - 0: this is an S-Video output - 1: this is an HDMI output - - So to create a video output device with 8 outputs where outputs 0-3 are - S-Video outputs and outputs 4-7 are HDMI outputs you would use the - following module options: - - num_outputs=8 output_types=0xf0 - -vid_cap_nr: give the desired videoX start number for each video capture device. - The default is -1 which will just take the first free number. This allows - you to map capture video nodes to specific videoX device nodes. Example: - - n_devs=4 vid_cap_nr=2,4,6,8 - - This will attempt to assign /dev/video2 for the video capture device of - the first vivid instance, video4 for the next up to video8 for the last - instance. If it can't succeed, then it will just take the next free - number. - -vid_out_nr: give the desired videoX start number for each video output device. - The default is -1 which will just take the first free number. - -vbi_cap_nr: give the desired vbiX start number for each vbi capture device. - The default is -1 which will just take the first free number. - -vbi_out_nr: give the desired vbiX start number for each vbi output device. - The default is -1 which will just take the first free number. - -radio_rx_nr: give the desired radioX start number for each radio receiver device. - The default is -1 which will just take the first free number. - -radio_tx_nr: give the desired radioX start number for each radio transmitter - device. The default is -1 which will just take the first free number. - -sdr_cap_nr: give the desired swradioX start number for each SDR capture device. - The default is -1 which will just take the first free number. - -ccs_cap_mode: specify the allowed video capture crop/compose/scaling combination - for each driver instance. Video capture devices can have any combination - of cropping, composing and scaling capabilities and this will tell the - vivid driver which of those is should emulate. By default the user can - select this through controls. - - The value is either -1 (controlled by the user) or a set of three bits, - each enabling (1) or disabling (0) one of the features: - - bit 0: Enable crop support. Cropping will take only part of the - incoming picture. - bit 1: Enable compose support. Composing will copy the incoming - picture into a larger buffer. - bit 2: Enable scaling support. Scaling can scale the incoming - picture. The scaler of the vivid driver can enlarge up - or down to four times the original size. The scaler is - very simple and low-quality. Simplicity and speed were - key, not quality. - - Note that this value is ignored by webcam inputs: those enumerate - discrete framesizes and that is incompatible with cropping, composing - or scaling. - -ccs_out_mode: specify the allowed video output crop/compose/scaling combination - for each driver instance. Video output devices can have any combination - of cropping, composing and scaling capabilities and this will tell the - vivid driver which of those is should emulate. By default the user can - select this through controls. - - The value is either -1 (controlled by the user) or a set of three bits, - each enabling (1) or disabling (0) one of the features: - - bit 0: Enable crop support. Cropping will take only part of the - outgoing buffer. - bit 1: Enable compose support. Composing will copy the incoming - buffer into a larger picture frame. - bit 2: Enable scaling support. Scaling can scale the incoming - buffer. The scaler of the vivid driver can enlarge up - or down to four times the original size. The scaler is - very simple and low-quality. Simplicity and speed were - key, not quality. - -multiplanar: select whether each device instance supports multi-planar formats, - and thus the V4L2 multi-planar API. By default device instances are - single-planar. - - This module option can override that for each instance. Values are: - - 1: this is a single-planar instance. - 2: this is a multi-planar instance. - -vivid_debug: enable driver debugging info - -no_error_inj: if set disable the error injecting controls. This option is - needed in order to run a tool like v4l2-compliance. Tools like that - exercise all controls including a control like 'Disconnect' which - emulates a USB disconnect, making the device inaccessible and so - all tests that v4l2-compliance is doing will fail afterwards. - - There may be other situations as well where you want to disable the - error injection support of vivid. When this option is set, then the - controls that select crop, compose and scale behavior are also - removed. Unless overridden by ccs_cap_mode and/or ccs_out_mode the - will default to enabling crop, compose and scaling. - -Taken together, all these module options allow you to precisely customize -the driver behavior and test your application with all sorts of permutations. -It is also very suitable to emulate hardware that is not yet available, e.g. -when developing software for a new upcoming device. - - -Section 2: Video Capture ------------------------- - -This is probably the most frequently used feature. The video capture device -can be configured by using the module options num_inputs, input_types and -ccs_cap_mode (see section 1 for more detailed information), but by default -four inputs are configured: a webcam, a TV tuner, an S-Video and an HDMI -input, one input for each input type. Those are described in more detail -below. - -Special attention has been given to the rate at which new frames become -available. The jitter will be around 1 jiffie (that depends on the HZ -configuration of your kernel, so usually 1/100, 1/250 or 1/1000 of a second), -but the long-term behavior is exactly following the framerate. So a -framerate of 59.94 Hz is really different from 60 Hz. If the framerate -exceeds your kernel's HZ value, then you will get dropped frames, but the -frame/field sequence counting will keep track of that so the sequence -count will skip whenever frames are dropped. - - -Section 2.1: Webcam Input -------------------------- - -The webcam input supports three framesizes: 320x180, 640x360 and 1280x720. It -supports frames per second settings of 10, 15, 25, 30, 50 and 60 fps. Which ones -are available depends on the chosen framesize: the larger the framesize, the -lower the maximum frames per second. - -The initially selected colorspace when you switch to the webcam input will be -sRGB. - - -Section 2.2: TV and S-Video Inputs ----------------------------------- - -The only difference between the TV and S-Video input is that the TV has a -tuner. Otherwise they behave identically. - -These inputs support audio inputs as well: one TV and one Line-In. They -both support all TV standards. If the standard is queried, then the Vivid -controls 'Standard Signal Mode' and 'Standard' determine what -the result will be. - -These inputs support all combinations of the field setting. Special care has -been taken to faithfully reproduce how fields are handled for the different -TV standards. This is particularly noticeable when generating a horizontally -moving image so the temporal effect of using interlaced formats becomes clearly -visible. For 50 Hz standards the top field is the oldest and the bottom field -is the newest in time. For 60 Hz standards that is reversed: the bottom field -is the oldest and the top field is the newest in time. - -When you start capturing in V4L2_FIELD_ALTERNATE mode the first buffer will -contain the top field for 50 Hz standards and the bottom field for 60 Hz -standards. This is what capture hardware does as well. - -Finally, for PAL/SECAM standards the first half of the top line contains noise. -This simulates the Wide Screen Signal that is commonly placed there. - -The initially selected colorspace when you switch to the TV or S-Video input -will be SMPTE-170M. - -The pixel aspect ratio will depend on the TV standard. The video aspect ratio -can be selected through the 'Standard Aspect Ratio' Vivid control. -Choices are '4x3', '16x9' which will give letterboxed widescreen video and -'16x9 Anamorphic' which will give full screen squashed anamorphic widescreen -video that will need to be scaled accordingly. - -The TV 'tuner' supports a frequency range of 44-958 MHz. Channels are available -every 6 MHz, starting from 49.25 MHz. For each channel the generated image -will be in color for the +/- 0.25 MHz around it, and in grayscale for -+/- 1 MHz around the channel. Beyond that it is just noise. The VIDIOC_G_TUNER -ioctl will return 100% signal strength for +/- 0.25 MHz and 50% for +/- 1 MHz. -It will also return correct afc values to show whether the frequency is too -low or too high. - -The audio subchannels that are returned are MONO for the +/- 1 MHz range around -a valid channel frequency. When the frequency is within +/- 0.25 MHz of the -channel it will return either MONO, STEREO, either MONO | SAP (for NTSC) or -LANG1 | LANG2 (for others), or STEREO | SAP. - -Which one is returned depends on the chosen channel, each next valid channel -will cycle through the possible audio subchannel combinations. This allows -you to test the various combinations by just switching channels.. - -Finally, for these inputs the v4l2_timecode struct is filled in in the -dequeued v4l2_buffer struct. - - -Section 2.3: HDMI Input ------------------------ - -The HDMI inputs supports all CEA-861 and DMT timings, both progressive and -interlaced, for pixelclock frequencies between 25 and 600 MHz. The field -mode for interlaced formats is always V4L2_FIELD_ALTERNATE. For HDMI the -field order is always top field first, and when you start capturing an -interlaced format you will receive the top field first. - -The initially selected colorspace when you switch to the HDMI input or -select an HDMI timing is based on the format resolution: for resolutions -less than or equal to 720x576 the colorspace is set to SMPTE-170M, for -others it is set to REC-709 (CEA-861 timings) or sRGB (VESA DMT timings). - -The pixel aspect ratio will depend on the HDMI timing: for 720x480 is it -set as for the NTSC TV standard, for 720x576 it is set as for the PAL TV -standard, and for all others a 1:1 pixel aspect ratio is returned. - -The video aspect ratio can be selected through the 'DV Timings Aspect Ratio' -Vivid control. Choices are 'Source Width x Height' (just use the -same ratio as the chosen format), '4x3' or '16x9', either of which can -result in pillarboxed or letterboxed video. - -For HDMI inputs it is possible to set the EDID. By default a simple EDID -is provided. You can only set the EDID for HDMI inputs. Internally, however, -the EDID is shared between all HDMI inputs. - -No interpretation is done of the EDID data with the exception of the -physical address. See the CEC section for more details. - -There is a maximum of 15 HDMI inputs (if there are more, then they will be -reduced to 15) since that's the limitation of the EDID physical address. - - -Section 3: Video Output ------------------------ - -The video output device can be configured by using the module options -num_outputs, output_types and ccs_out_mode (see section 1 for more detailed -information), but by default two outputs are configured: an S-Video and an -HDMI input, one output for each output type. Those are described in more detail -below. - -Like with video capture the framerate is also exact in the long term. - - -Section 3.1: S-Video Output ---------------------------- - -This output supports audio outputs as well: "Line-Out 1" and "Line-Out 2". -The S-Video output supports all TV standards. - -This output supports all combinations of the field setting. - -The initially selected colorspace when you switch to the TV or S-Video input -will be SMPTE-170M. - - -Section 3.2: HDMI Output ------------------------- - -The HDMI output supports all CEA-861 and DMT timings, both progressive and -interlaced, for pixelclock frequencies between 25 and 600 MHz. The field -mode for interlaced formats is always V4L2_FIELD_ALTERNATE. - -The initially selected colorspace when you switch to the HDMI output or -select an HDMI timing is based on the format resolution: for resolutions -less than or equal to 720x576 the colorspace is set to SMPTE-170M, for -others it is set to REC-709 (CEA-861 timings) or sRGB (VESA DMT timings). - -The pixel aspect ratio will depend on the HDMI timing: for 720x480 is it -set as for the NTSC TV standard, for 720x576 it is set as for the PAL TV -standard, and for all others a 1:1 pixel aspect ratio is returned. - -An HDMI output has a valid EDID which can be obtained through VIDIOC_G_EDID. - -There is a maximum of 15 HDMI outputs (if there are more, then they will be -reduced to 15) since that's the limitation of the EDID physical address. See -also the CEC section for more details. - -Section 4: VBI Capture ----------------------- - -There are three types of VBI capture devices: those that only support raw -(undecoded) VBI, those that only support sliced (decoded) VBI and those that -support both. This is determined by the node_types module option. In all -cases the driver will generate valid VBI data: for 60 Hz standards it will -generate Closed Caption and XDS data. The closed caption stream will -alternate between "Hello world!" and "Closed captions test" every second. -The XDS stream will give the current time once a minute. For 50 Hz standards -it will generate the Wide Screen Signal which is based on the actual Video -Aspect Ratio control setting and teletext pages 100-159, one page per frame. - -The VBI device will only work for the S-Video and TV inputs, it will give -back an error if the current input is a webcam or HDMI. - - -Section 5: VBI Output ---------------------- - -There are three types of VBI output devices: those that only support raw -(undecoded) VBI, those that only support sliced (decoded) VBI and those that -support both. This is determined by the node_types module option. - -The sliced VBI output supports the Wide Screen Signal and the teletext signal -for 50 Hz standards and Closed Captioning + XDS for 60 Hz standards. - -The VBI device will only work for the S-Video output, it will give -back an error if the current output is HDMI. - - -Section 6: Radio Receiver -------------------------- - -The radio receiver emulates an FM/AM/SW receiver. The FM band also supports RDS. -The frequency ranges are: - - FM: 64 MHz - 108 MHz - AM: 520 kHz - 1710 kHz - SW: 2300 kHz - 26.1 MHz - -Valid channels are emulated every 1 MHz for FM and every 100 kHz for AM and SW. -The signal strength decreases the further the frequency is from the valid -frequency until it becomes 0% at +/- 50 kHz (FM) or 5 kHz (AM/SW) from the -ideal frequency. The initial frequency when the driver is loaded is set to -95 MHz. - -The FM receiver supports RDS as well, both using 'Block I/O' and 'Controls' -modes. In the 'Controls' mode the RDS information is stored in read-only -controls. These controls are updated every time the frequency is changed, -or when the tuner status is requested. The Block I/O method uses the read() -interface to pass the RDS blocks on to the application for decoding. - -The RDS signal is 'detected' for +/- 12.5 kHz around the channel frequency, -and the further the frequency is away from the valid frequency the more RDS -errors are randomly introduced into the block I/O stream, up to 50% of all -blocks if you are +/- 12.5 kHz from the channel frequency. All four errors -can occur in equal proportions: blocks marked 'CORRECTED', blocks marked -'ERROR', blocks marked 'INVALID' and dropped blocks. - -The generated RDS stream contains all the standard fields contained in a -0B group, and also radio text and the current time. - -The receiver supports HW frequency seek, either in Bounded mode, Wrap Around -mode or both, which is configurable with the "Radio HW Seek Mode" control. - - -Section 7: Radio Transmitter ----------------------------- - -The radio transmitter emulates an FM/AM/SW transmitter. The FM band also supports RDS. -The frequency ranges are: - - FM: 64 MHz - 108 MHz - AM: 520 kHz - 1710 kHz - SW: 2300 kHz - 26.1 MHz - -The initial frequency when the driver is loaded is 95.5 MHz. - -The FM transmitter supports RDS as well, both using 'Block I/O' and 'Controls' -modes. In the 'Controls' mode the transmitted RDS information is configured -using controls, and in 'Block I/O' mode the blocks are passed to the driver -using write(). - - -Section 8: Software Defined Radio Receiver ------------------------------------------- - -The SDR receiver has three frequency bands for the ADC tuner: - - - 300 kHz - - 900 kHz - 2800 kHz - - 3200 kHz - -The RF tuner supports 50 MHz - 2000 MHz. - -The generated data contains the In-phase and Quadrature components of a -1 kHz tone that has an amplitude of sqrt(2). - - -Section 9: Controls -------------------- - -Different devices support different controls. The sections below will describe -each control and which devices support them. - - -Section 9.1: User Controls - Test Controls ------------------------------------------- - -The Button, Boolean, Integer 32 Bits, Integer 64 Bits, Menu, String, Bitmask and -Integer Menu are controls that represent all possible control types. The Menu -control and the Integer Menu control both have 'holes' in their menu list, -meaning that one or more menu items return EINVAL when VIDIOC_QUERYMENU is called. -Both menu controls also have a non-zero minimum control value. These features -allow you to check if your application can handle such things correctly. -These controls are supported for every device type. - - -Section 9.2: User Controls - Video Capture ------------------------------------------- - -The following controls are specific to video capture. - -The Brightness, Contrast, Saturation and Hue controls actually work and are -standard. There is one special feature with the Brightness control: each -video input has its own brightness value, so changing input will restore -the brightness for that input. In addition, each video input uses a different -brightness range (minimum and maximum control values). Switching inputs will -cause a control event to be sent with the V4L2_EVENT_CTRL_CH_RANGE flag set. -This allows you to test controls that can change their range. - -The 'Gain, Automatic' and Gain controls can be used to test volatile controls: -if 'Gain, Automatic' is set, then the Gain control is volatile and changes -constantly. If 'Gain, Automatic' is cleared, then the Gain control is a normal -control. - -The 'Horizontal Flip' and 'Vertical Flip' controls can be used to flip the -image. These combine with the 'Sensor Flipped Horizontally/Vertically' Vivid -controls. - -The 'Alpha Component' control can be used to set the alpha component for -formats containing an alpha channel. - - -Section 9.3: User Controls - Audio ----------------------------------- - -The following controls are specific to video capture and output and radio -receivers and transmitters. - -The 'Volume' and 'Mute' audio controls are typical for such devices to -control the volume and mute the audio. They don't actually do anything in -the vivid driver. - - -Section 9.4: Vivid Controls ---------------------------- - -These vivid custom controls control the image generation, error injection, etc. - - -Section 9.4.1: Test Pattern Controls ------------------------------------- - -The Test Pattern Controls are all specific to video capture. - -Test Pattern: selects which test pattern to use. Use the CSC Colorbar for - testing colorspace conversions: the colors used in that test pattern - map to valid colors in all colorspaces. The colorspace conversion - is disabled for the other test patterns. - -OSD Text Mode: selects whether the text superimposed on the - test pattern should be shown, and if so, whether only counters should - be displayed or the full text. - -Horizontal Movement: selects whether the test pattern should - move to the left or right and at what speed. - -Vertical Movement: does the same for the vertical direction. - -Show Border: show a two-pixel wide border at the edge of the actual image, - excluding letter or pillarboxing. - -Show Square: show a square in the middle of the image. If the image is - displayed with the correct pixel and image aspect ratio corrections, - then the width and height of the square on the monitor should be - the same. - -Insert SAV Code in Image: adds a SAV (Start of Active Video) code to the image. - This can be used to check if such codes in the image are inadvertently - interpreted instead of being ignored. - -Insert EAV Code in Image: does the same for the EAV (End of Active Video) code. - - -Section 9.4.2: Capture Feature Selection Controls -------------------------------------------------- - -These controls are all specific to video capture. - -Sensor Flipped Horizontally: the image is flipped horizontally and the - V4L2_IN_ST_HFLIP input status flag is set. This emulates the case where - a sensor is for example mounted upside down. - -Sensor Flipped Vertically: the image is flipped vertically and the - V4L2_IN_ST_VFLIP input status flag is set. This emulates the case where - a sensor is for example mounted upside down. - -Standard Aspect Ratio: selects if the image aspect ratio as used for the TV or - S-Video input should be 4x3, 16x9 or anamorphic widescreen. This may - introduce letterboxing. - -DV Timings Aspect Ratio: selects if the image aspect ratio as used for the HDMI - input should be the same as the source width and height ratio, or if - it should be 4x3 or 16x9. This may introduce letter or pillarboxing. - -Timestamp Source: selects when the timestamp for each buffer is taken. - -Colorspace: selects which colorspace should be used when generating the image. - This only applies if the CSC Colorbar test pattern is selected, - otherwise the test pattern will go through unconverted. - This behavior is also what you want, since a 75% Colorbar - should really have 75% signal intensity and should not be affected - by colorspace conversions. - - Changing the colorspace will result in the V4L2_EVENT_SOURCE_CHANGE - to be sent since it emulates a detected colorspace change. - -Transfer Function: selects which colorspace transfer function should be used when - generating an image. This only applies if the CSC Colorbar test pattern is - selected, otherwise the test pattern will go through unconverted. - This behavior is also what you want, since a 75% Colorbar - should really have 75% signal intensity and should not be affected - by colorspace conversions. - - Changing the transfer function will result in the V4L2_EVENT_SOURCE_CHANGE - to be sent since it emulates a detected colorspace change. - -Y'CbCr Encoding: selects which Y'CbCr encoding should be used when generating - a Y'CbCr image. This only applies if the format is set to a Y'CbCr format - as opposed to an RGB format. - - Changing the Y'CbCr encoding will result in the V4L2_EVENT_SOURCE_CHANGE - to be sent since it emulates a detected colorspace change. - -Quantization: selects which quantization should be used for the RGB or Y'CbCr - encoding when generating the test pattern. - - Changing the quantization will result in the V4L2_EVENT_SOURCE_CHANGE - to be sent since it emulates a detected colorspace change. - -Limited RGB Range (16-235): selects if the RGB range of the HDMI source should - be limited or full range. This combines with the Digital Video 'Rx RGB - Quantization Range' control and can be used to test what happens if - a source provides you with the wrong quantization range information. - See the description of that control for more details. - -Apply Alpha To Red Only: apply the alpha channel as set by the 'Alpha Component' - user control to the red color of the test pattern only. - -Enable Capture Cropping: enables crop support. This control is only present if - the ccs_cap_mode module option is set to the default value of -1 and if - the no_error_inj module option is set to 0 (the default). - -Enable Capture Composing: enables composing support. This control is only - present if the ccs_cap_mode module option is set to the default value of - -1 and if the no_error_inj module option is set to 0 (the default). - -Enable Capture Scaler: enables support for a scaler (maximum 4 times upscaling - and downscaling). This control is only present if the ccs_cap_mode - module option is set to the default value of -1 and if the no_error_inj - module option is set to 0 (the default). - -Maximum EDID Blocks: determines how many EDID blocks the driver supports. - Note that the vivid driver does not actually interpret new EDID - data, it just stores it. It allows for up to 256 EDID blocks - which is the maximum supported by the standard. - -Fill Percentage of Frame: can be used to draw only the top X percent - of the image. Since each frame has to be drawn by the driver, this - demands a lot of the CPU. For large resolutions this becomes - problematic. By drawing only part of the image this CPU load can - be reduced. - - -Section 9.4.3: Output Feature Selection Controls ------------------------------------------------- - -These controls are all specific to video output. - -Enable Output Cropping: enables crop support. This control is only present if - the ccs_out_mode module option is set to the default value of -1 and if - the no_error_inj module option is set to 0 (the default). - -Enable Output Composing: enables composing support. This control is only - present if the ccs_out_mode module option is set to the default value of - -1 and if the no_error_inj module option is set to 0 (the default). - -Enable Output Scaler: enables support for a scaler (maximum 4 times upscaling - and downscaling). This control is only present if the ccs_out_mode - module option is set to the default value of -1 and if the no_error_inj - module option is set to 0 (the default). - - -Section 9.4.4: Error Injection Controls ---------------------------------------- - -The following two controls are only valid for video and vbi capture. - -Standard Signal Mode: selects the behavior of VIDIOC_QUERYSTD: what should - it return? - - Changing this control will result in the V4L2_EVENT_SOURCE_CHANGE - to be sent since it emulates a changed input condition (e.g. a cable - was plugged in or out). - -Standard: selects the standard that VIDIOC_QUERYSTD should return if the - previous control is set to "Selected Standard". - - Changing this control will result in the V4L2_EVENT_SOURCE_CHANGE - to be sent since it emulates a changed input standard. - - -The following two controls are only valid for video capture. - -DV Timings Signal Mode: selects the behavior of VIDIOC_QUERY_DV_TIMINGS: what - should it return? - - Changing this control will result in the V4L2_EVENT_SOURCE_CHANGE - to be sent since it emulates a changed input condition (e.g. a cable - was plugged in or out). - -DV Timings: selects the timings the VIDIOC_QUERY_DV_TIMINGS should return - if the previous control is set to "Selected DV Timings". - - Changing this control will result in the V4L2_EVENT_SOURCE_CHANGE - to be sent since it emulates changed input timings. - - -The following controls are only present if the no_error_inj module option -is set to 0 (the default). These controls are valid for video and vbi -capture and output streams and for the SDR capture device except for the -Disconnect control which is valid for all devices. - -Wrap Sequence Number: test what happens when you wrap the sequence number in - struct v4l2_buffer around. - -Wrap Timestamp: test what happens when you wrap the timestamp in struct - v4l2_buffer around. - -Percentage of Dropped Buffers: sets the percentage of buffers that - are never returned by the driver (i.e., they are dropped). - -Disconnect: emulates a USB disconnect. The device will act as if it has - been disconnected. Only after all open filehandles to the device - node have been closed will the device become 'connected' again. - -Inject V4L2_BUF_FLAG_ERROR: when pressed, the next frame returned by - the driver will have the error flag set (i.e. the frame is marked - corrupt). - -Inject VIDIOC_REQBUFS Error: when pressed, the next REQBUFS or CREATE_BUFS - ioctl call will fail with an error. To be precise: the videobuf2 - queue_setup() op will return -EINVAL. - -Inject VIDIOC_QBUF Error: when pressed, the next VIDIOC_QBUF or - VIDIOC_PREPARE_BUFFER ioctl call will fail with an error. To be - precise: the videobuf2 buf_prepare() op will return -EINVAL. - -Inject VIDIOC_STREAMON Error: when pressed, the next VIDIOC_STREAMON ioctl - call will fail with an error. To be precise: the videobuf2 - start_streaming() op will return -EINVAL. - -Inject Fatal Streaming Error: when pressed, the streaming core will be - marked as having suffered a fatal error, the only way to recover - from that is to stop streaming. To be precise: the videobuf2 - vb2_queue_error() function is called. - - -Section 9.4.5: VBI Raw Capture Controls ---------------------------------------- - -Interlaced VBI Format: if set, then the raw VBI data will be interlaced instead - of providing it grouped by field. - - -Section 9.5: Digital Video Controls ------------------------------------ - -Rx RGB Quantization Range: sets the RGB quantization detection of the HDMI - input. This combines with the Vivid 'Limited RGB Range (16-235)' - control and can be used to test what happens if a source provides - you with the wrong quantization range information. This can be tested - by selecting an HDMI input, setting this control to Full or Limited - range and selecting the opposite in the 'Limited RGB Range (16-235)' - control. The effect is easy to see if the 'Gray Ramp' test pattern - is selected. - -Tx RGB Quantization Range: sets the RGB quantization detection of the HDMI - output. It is currently not used for anything in vivid, but most HDMI - transmitters would typically have this control. - -Transmit Mode: sets the transmit mode of the HDMI output to HDMI or DVI-D. This - affects the reported colorspace since DVI_D outputs will always use - sRGB. - - -Section 9.6: FM Radio Receiver Controls ---------------------------------------- - -RDS Reception: set if the RDS receiver should be enabled. - -RDS Program Type: -RDS PS Name: -RDS Radio Text: -RDS Traffic Announcement: -RDS Traffic Program: -RDS Music: these are all read-only controls. If RDS Rx I/O Mode is set to - "Block I/O", then they are inactive as well. If RDS Rx I/O Mode is set - to "Controls", then these controls report the received RDS data. Note - that the vivid implementation of this is pretty basic: they are only - updated when you set a new frequency or when you get the tuner status - (VIDIOC_G_TUNER). - -Radio HW Seek Mode: can be one of "Bounded", "Wrap Around" or "Both". This - determines if VIDIOC_S_HW_FREQ_SEEK will be bounded by the frequency - range or wrap-around or if it is selectable by the user. - -Radio Programmable HW Seek: if set, then the user can provide the lower and - upper bound of the HW Seek. Otherwise the frequency range boundaries - will be used. - -Generate RBDS Instead of RDS: if set, then generate RBDS (the US variant of - RDS) data instead of RDS (European-style RDS). This affects only the - PICODE and PTY codes. - -RDS Rx I/O Mode: this can be "Block I/O" where the RDS blocks have to be read() - by the application, or "Controls" where the RDS data is provided by - the RDS controls mentioned above. - - -Section 9.7: FM Radio Modulator Controls ----------------------------------------- - -RDS Program ID: -RDS Program Type: -RDS PS Name: -RDS Radio Text: -RDS Stereo: -RDS Artificial Head: -RDS Compressed: -RDS Dynamic PTY: -RDS Traffic Announcement: -RDS Traffic Program: -RDS Music: these are all controls that set the RDS data that is transmitted by - the FM modulator. - -RDS Tx I/O Mode: this can be "Block I/O" where the application has to use write() - to pass the RDS blocks to the driver, or "Controls" where the RDS data is - provided by the RDS controls mentioned above. - - -Section 10: Video, VBI and RDS Looping --------------------------------------- - -The vivid driver supports looping of video output to video input, VBI output -to VBI input and RDS output to RDS input. For video/VBI looping this emulates -as if a cable was hooked up between the output and input connector. So video -and VBI looping is only supported between S-Video and HDMI inputs and outputs. -VBI is only valid for S-Video as it makes no sense for HDMI. - -Since radio is wireless this looping always happens if the radio receiver -frequency is close to the radio transmitter frequency. In that case the radio -transmitter will 'override' the emulated radio stations. - -Looping is currently supported only between devices created by the same -vivid driver instance. - - -Section 10.1: Video and Sliced VBI looping ------------------------------------------- - -The way to enable video/VBI looping is currently fairly crude. A 'Loop Video' -control is available in the "Vivid" control class of the video -capture and VBI capture devices. When checked the video looping will be enabled. -Once enabled any video S-Video or HDMI input will show a static test pattern -until the video output has started. At that time the video output will be -looped to the video input provided that: - -- the input type matches the output type. So the HDMI input cannot receive - video from the S-Video output. - -- the video resolution of the video input must match that of the video output. - So it is not possible to loop a 50 Hz (720x576) S-Video output to a 60 Hz - (720x480) S-Video input, or a 720p60 HDMI output to a 1080p30 input. - -- the pixel formats must be identical on both sides. Otherwise the driver would - have to do pixel format conversion as well, and that's taking things too far. - -- the field settings must be identical on both sides. Same reason as above: - requiring the driver to convert from one field format to another complicated - matters too much. This also prohibits capturing with 'Field Top' or 'Field - Bottom' when the output video is set to 'Field Alternate'. This combination, - while legal, became too complicated to support. Both sides have to be 'Field - Alternate' for this to work. Also note that for this specific case the - sequence and field counting in struct v4l2_buffer on the capture side may not - be 100% accurate. - -- field settings V4L2_FIELD_SEQ_TB/BT are not supported. While it is possible to - implement this, it would mean a lot of work to get this right. Since these - field values are rarely used the decision was made not to implement this for - now. - -- on the input side the "Standard Signal Mode" for the S-Video input or the - "DV Timings Signal Mode" for the HDMI input should be configured so that a - valid signal is passed to the video input. - -The framerates do not have to match, although this might change in the future. - -By default you will see the OSD text superimposed on top of the looped video. -This can be turned off by changing the "OSD Text Mode" control of the video -capture device. - -For VBI looping to work all of the above must be valid and in addition the vbi -output must be configured for sliced VBI. The VBI capture side can be configured -for either raw or sliced VBI. Note that at the moment only CC/XDS (60 Hz formats) -and WSS (50 Hz formats) VBI data is looped. Teletext VBI data is not looped. - - -Section 10.2: Radio & RDS Looping ---------------------------------- - -As mentioned in section 6 the radio receiver emulates stations are regular -frequency intervals. Depending on the frequency of the radio receiver a -signal strength value is calculated (this is returned by VIDIOC_G_TUNER). -However, it will also look at the frequency set by the radio transmitter and -if that results in a higher signal strength than the settings of the radio -transmitter will be used as if it was a valid station. This also includes -the RDS data (if any) that the transmitter 'transmits'. This is received -faithfully on the receiver side. Note that when the driver is loaded the -frequencies of the radio receiver and transmitter are not identical, so -initially no looping takes place. - - -Section 11: Cropping, Composing, Scaling ----------------------------------------- - -This driver supports cropping, composing and scaling in any combination. Normally -which features are supported can be selected through the Vivid controls, -but it is also possible to hardcode it when the module is loaded through the -ccs_cap_mode and ccs_out_mode module options. See section 1 on the details of -these module options. - -This allows you to test your application for all these variations. - -Note that the webcam input never supports cropping, composing or scaling. That -only applies to the TV/S-Video/HDMI inputs and outputs. The reason is that -webcams, including this virtual implementation, normally use -VIDIOC_ENUM_FRAMESIZES to list a set of discrete framesizes that it supports. -And that does not combine with cropping, composing or scaling. This is -primarily a limitation of the V4L2 API which is carefully reproduced here. - -The minimum and maximum resolutions that the scaler can achieve are 16x16 and -(4096 * 4) x (2160 x 4), but it can only scale up or down by a factor of 4 or -less. So for a source resolution of 1280x720 the minimum the scaler can do is -320x180 and the maximum is 5120x2880. You can play around with this using the -qv4l2 test tool and you will see these dependencies. - -This driver also supports larger 'bytesperline' settings, something that -VIDIOC_S_FMT allows but that few drivers implement. - -The scaler is a simple scaler that uses the Coarse Bresenham algorithm. It's -designed for speed and simplicity, not quality. - -If the combination of crop, compose and scaling allows it, then it is possible -to change crop and compose rectangles on the fly. - - -Section 12: Formats -------------------- - -The driver supports all the regular packed and planar 4:4:4, 4:2:2 and 4:2:0 -YUYV formats, 8, 16, 24 and 32 RGB packed formats and various multiplanar -formats. - -The alpha component can be set through the 'Alpha Component' User control -for those formats that support it. If the 'Apply Alpha To Red Only' control -is set, then the alpha component is only used for the color red and set to -0 otherwise. - -The driver has to be configured to support the multiplanar formats. By default -the driver instances are single-planar. This can be changed by setting the -multiplanar module option, see section 1 for more details on that option. - -If the driver instance is using the multiplanar formats/API, then the first -single planar format (YUYV) and the multiplanar NV16M and NV61M formats the -will have a plane that has a non-zero data_offset of 128 bytes. It is rare for -data_offset to be non-zero, so this is a useful feature for testing applications. - -Video output will also honor any data_offset that the application set. - - -Section 13: Capture Overlay ---------------------------- - -Note: capture overlay support is implemented primarily to test the existing -V4L2 capture overlay API. In practice few if any GPUs support such overlays -anymore, and neither are they generally needed anymore since modern hardware -is so much more capable. By setting flag 0x10000 in the node_types module -option the vivid driver will create a simple framebuffer device that can be -used for testing this API. Whether this API should be used for new drivers is -questionable. - -This driver has support for a destructive capture overlay with bitmap clipping -and list clipping (up to 16 rectangles) capabilities. Overlays are not -supported for multiplanar formats. It also honors the struct v4l2_window field -setting: if it is set to FIELD_TOP or FIELD_BOTTOM and the capture setting is -FIELD_ALTERNATE, then only the top or bottom fields will be copied to the overlay. - -The overlay only works if you are also capturing at that same time. This is a -vivid limitation since it copies from a buffer to the overlay instead of -filling the overlay directly. And if you are not capturing, then no buffers -are available to fill. - -In addition, the pixelformat of the capture format and that of the framebuffer -must be the same for the overlay to work. Otherwise VIDIOC_OVERLAY will return -an error. - -In order to really see what it going on you will need to create two vivid -instances: the first with a framebuffer enabled. You configure the capture -overlay of the second instance to use the framebuffer of the first, then -you start capturing in the second instance. For the first instance you setup -the output overlay for the video output, turn on video looping and capture -to see the blended framebuffer overlay that's being written to by the second -instance. This setup would require the following commands: - - $ sudo modprobe vivid n_devs=2 node_types=0x10101,0x1 - $ v4l2-ctl -d1 --find-fb - /dev/fb1 is the framebuffer associated with base address 0x12800000 - $ sudo v4l2-ctl -d2 --set-fbuf fb=1 - $ v4l2-ctl -d1 --set-fbuf fb=1 - $ v4l2-ctl -d0 --set-fmt-video=pixelformat='AR15' - $ v4l2-ctl -d1 --set-fmt-video-out=pixelformat='AR15' - $ v4l2-ctl -d2 --set-fmt-video=pixelformat='AR15' - $ v4l2-ctl -d0 -i2 - $ v4l2-ctl -d2 -i2 - $ v4l2-ctl -d2 -c horizontal_movement=4 - $ v4l2-ctl -d1 --overlay=1 - $ v4l2-ctl -d1 -c loop_video=1 - $ v4l2-ctl -d2 --stream-mmap --overlay=1 - -And from another console: - - $ v4l2-ctl -d1 --stream-out-mmap - -And yet another console: - - $ qv4l2 - -and start streaming. - -As you can see, this is not for the faint of heart... - - -Section 14: Output Overlay --------------------------- - -Note: output overlays are primarily implemented in order to test the existing -V4L2 output overlay API. Whether this API should be used for new drivers is -questionable. - -This driver has support for an output overlay and is capable of: - - - bitmap clipping, - - list clipping (up to 16 rectangles) - - chromakey - - source chromakey - - global alpha - - local alpha - - local inverse alpha - -Output overlays are not supported for multiplanar formats. In addition, the -pixelformat of the capture format and that of the framebuffer must be the -same for the overlay to work. Otherwise VIDIOC_OVERLAY will return an error. - -Output overlays only work if the driver has been configured to create a -framebuffer by setting flag 0x10000 in the node_types module option. The -created framebuffer has a size of 720x576 and supports ARGB 1:5:5:5 and -RGB 5:6:5. - -In order to see the effects of the various clipping, chromakeying or alpha -processing capabilities you need to turn on video looping and see the results -on the capture side. The use of the clipping, chromakeying or alpha processing -capabilities will slow down the video loop considerably as a lot of checks have -to be done per pixel. - - -Section 15: CEC (Consumer Electronics Control) ----------------------------------------------- - -If there are HDMI inputs then a CEC adapter will be created that has -the same number of input ports. This is the equivalent of e.g. a TV that -has that number of inputs. Each HDMI output will also create a -CEC adapter that is hooked up to the corresponding input port, or (if there -are more outputs than inputs) is not hooked up at all. In other words, -this is the equivalent of hooking up each output device to an input port of -the TV. Any remaining output devices remain unconnected. - -The EDID that each output reads reports a unique CEC physical address that is -based on the physical address of the EDID of the input. So if the EDID of the -receiver has physical address A.B.0.0, then each output will see an EDID -containing physical address A.B.C.0 where C is 1 to the number of inputs. If -there are more outputs than inputs then the remaining outputs have a CEC adapter -that is disabled and reports an invalid physical address. - - -Section 16: Some Future Improvements ------------------------------------- - -Just as a reminder and in no particular order: - -- Add a virtual alsa driver to test audio -- Add virtual sub-devices and media controller support -- Some support for testing compressed video -- Add support to loop raw VBI output to raw VBI input -- Add support to loop teletext sliced VBI output to VBI input -- Fix sequence/field numbering when looping of video with alternate fields -- Add support for V4L2_CID_BG_COLOR for video outputs -- Add ARGB888 overlay support: better testing of the alpha channel -- Improve pixel aspect support in the tpg code by passing a real v4l2_fract -- Use per-queue locks and/or per-device locks to improve throughput -- Add support to loop from a specific output to a specific input across - vivid instances -- The SDR radio should use the same 'frequencies' for stations as the normal - radio receiver, and give back noise if the frequency doesn't match up with - a station frequency -- Make a thread for the RDS generation, that would help in particular for the - "Controls" RDS Rx I/O Mode as the read-only RDS controls could be updated - in real-time. -- Changing the EDID should cause hotplug detect emulation to happen. diff --git a/Documentation/video4linux/zr364xx.txt b/Documentation/video4linux/zr364xx.txt deleted file mode 100644 index d98e4d302977..000000000000 --- a/Documentation/video4linux/zr364xx.txt +++ /dev/null @@ -1,69 +0,0 @@ -Zoran 364xx based USB webcam module version 0.72 -site: http://royale.zerezo.com/zr364xx/ -mail: royale@zerezo.com - -introduction: -This brings support under Linux for the Aiptek PocketDV 3300 in webcam mode. -If you just want to get on your PC the pictures and movies on the camera, you should use the usb-storage module instead. -The driver works with several other cameras in webcam mode (see the list below). -Maybe this code can work for other JPEG/USB cams based on the Coach chips from Zoran? -Possible chipsets are : ZR36430 (ZR36430BGC) and maybe ZR36431, ZR36440, ZR36442... -You can try the experience changing the vendor/product ID values (look at the source code). -You can get these values by looking at /var/log/messages when you plug your camera, or by typing : cat /proc/bus/usb/devices. -If you manage to use your cam with this code, you can send me a mail (royale@zerezo.com) with the name of your cam and a patch if needed. -This is a beta release of the driver. -Since version 0.70, this driver is only compatible with V4L2 API and 2.6.x kernels. -If you need V4L1 or 2.4x kernels support, please use an older version, but the code is not maintained anymore. -Good luck! - -install: -In order to use this driver, you must compile it with your kernel. -Location: Device Drivers -> Multimedia devices -> Video For Linux -> Video Capture Adapters -> V4L USB devices - -usage: -modprobe zr364xx debug=X mode=Y - - debug : set to 1 to enable verbose debug messages - - mode : 0 = 320x240, 1 = 160x120, 2 = 640x480 -You can then use the camera with V4L2 compatible applications, for example Ekiga. -To capture a single image, try this: dd if=/dev/video0 of=test.jpg bs=1M count=1 - -links : -http://mxhaard.free.fr/ (support for many others cams including some Aiptek PocketDV) -http://www.harmwal.nl/pccam880/ (this project also supports cameras based on this chipset) - -supported devices: ------- ------- ----------- ----- -Vendor Product Distributor Model ------- ------- ----------- ----- -0x08ca 0x0109 Aiptek PocketDV 3300 -0x08ca 0x0109 Maxell Maxcam PRO DV3 -0x041e 0x4024 Creative PC-CAM 880 -0x0d64 0x0108 Aiptek Fidelity 3200 -0x0d64 0x0108 Praktica DCZ 1.3 S -0x0d64 0x0108 Genius Digital Camera (?) -0x0d64 0x0108 DXG Technology Fashion Cam -0x0546 0x3187 Polaroid iON 230 -0x0d64 0x3108 Praktica Exakta DC 2200 -0x0d64 0x3108 Genius G-Shot D211 -0x0595 0x4343 Concord Eye-Q Duo 1300 -0x0595 0x4343 Concord Eye-Q Duo 2000 -0x0595 0x4343 Fujifilm EX-10 -0x0595 0x4343 Ricoh RDC-6000 -0x0595 0x4343 Digitrex DSC 1300 -0x0595 0x4343 Firstline FDC 2000 -0x0bb0 0x500d Concord EyeQ Go Wireless -0x0feb 0x2004 CRS Electronic 3.3 Digital Camera -0x0feb 0x2004 Packard Bell DSC-300 -0x055f 0xb500 Mustek MDC 3000 -0x08ca 0x2062 Aiptek PocketDV 5700 -0x052b 0x1a18 Chiphead Megapix V12 -0x04c8 0x0729 Konica Revio 2 -0x04f2 0xa208 Creative PC-CAM 850 -0x0784 0x0040 Traveler Slimline X5 -0x06d6 0x0034 Trust Powerc@m 750 -0x0a17 0x0062 Pentax Optio 50L -0x06d6 0x003b Trust Powerc@m 970Z -0x0a17 0x004e Pentax Optio 50 -0x041e 0x405d Creative DiVi CAM 516 -0x08ca 0x2102 Aiptek DV T300 -0x06d6 0x003d Trust Powerc@m 910Z |
