Dec 2012 11:30:00 -0300 Subject: [media] au0828: remove forced dependency of VIDEO_AU0828 on VIDEO_V4L2 This patch removes the dependendency of VIDEO_AU0828 on VIDEO_V4L2 by creating a new Kconfig option, VIDEO_AU0828_V4L2, which enables analog video capture support and depends on VIDEO_V4L2 itself. With VIDEO_AU0828_V4L2 disabled, the driver will only support digital television and will not depend on the v4l2-core. With VIDEO_AU0828_V4L2 enabled, the driver will be built with the analog v4l2 support included. By default, the VIDEO_AU0828_V4L2 option will be set to Y, so as to preserve the original behavior.

Likewise, setting FIMC_REG_CITRGFMT_FLIP_Y_MIRROR bit causes Y-axis image flip (horizontal flip) and thus it corresponds to V4L2_CID_HFLIP. Currently the driver does X-axis flip when V4L2_CID_HFLIP is set and Y-axis flip for V4L2_CID_VFLIP. Fix this incorrect assignment by setting proper FIMC_REG_CITRGFMT register bits for ctx->hflip and ctx->vflip.

Overview and features -======================== -This driver supports the video interface of the devices mounting the ET61X151 -or ET61X251 PC Camera Controllers. - -It's worth to note that Etoms Electronics has never collaborated with the -author during the development of this project; despite several requests, -Etoms Electronics also refused to release enough detailed specifications of -the video compression engine. - -The driver relies on the Video4Linux2 and USB core modules. It has been -designed to run properly on SMP systems as well. - -The latest version of the ET61X[12]51 driver can be found at the following URL: -http://www.linux-projects.org/ - -Some of the features of the driver are: - -- full compliance with the Video4Linux2 API (see also "Notes for V4L2 - application developers" paragraph); -- available mmap or read/poll methods for video streaming through isochronous - data transfers; -- automatic detection of image sensor; -- support for any window resolutions and optional panning within the maximum - pixel area of image sensor; -- image downscaling with arbitrary scaling factors from 1 and 2 in both - directions (see "Notes for V4L2 application developers" paragraph); -- two different video formats for uncompressed or compressed data in low or - high compression quality (see also "Notes for V4L2 application developers" - paragraph); -- full support for the capabilities of every possible image sensors that can - be connected to the ET61X[12]51 bridges, including, for instance, red, green, - blue and global gain adjustments and exposure control (see "Supported - devices" paragraph for details); -- use of default color settings for sunlight conditions; -- dynamic I/O interface for both ET61X[12]51 and image sensor control (see - "Optional device control through 'sysfs'" paragraph); -- dynamic driver control thanks to various module parameters (see "Module - parameters" paragraph); -- up to 64 cameras can be handled at the same time; they can be connected and - disconnected from the host many times without turning off the computer, if - the system supports hotplugging; -- no known bugs. - - -5. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux and -USB. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - -To enable advanced debugging functionality on the device through /sysfs: - - # Multimedia devices - # - CONFIG_VIDEO_ADV_DEBUG=y - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, the modules below are -necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_ET61X251=m - - -6. Module loading -================= -To use the driver, it is necessary to load the "et61x251" module into memory -after every other module required: "videodev", "v4l2_common", "compat_ioctl32", -"usbcore" and, depending on the USB host controller you have, "ehci-hcd", -"uhci-hcd" or "ohci-hcd". - -Loading can be done as shown below: - - [root@localhost home]# modprobe et61x251 - -At this point the devices should be recognized. You can invoke "dmesg" to -analyze kernel messages and verify that the loading process has gone well: - - [user@localhost home]$ dmesg - - -7. Module parameters -==================== -Module parameters are listed below: -------------------------------------------------------------------------------- -Name: video_nr -Type: short array (min = 0, max = 64) -Syntax: <-1|n[,...]> -Description: Specify V4L2 minor mode number: - -1 = use next available - n = use minor number n - You can specify up to 64 cameras this way. - For example: - video_nr=-1,2,-1 would assign minor number 2 to the second - registered camera and use auto for the first one and for every - other camera. -Default: -1 -------------------------------------------------------------------------------- -Name: force_munmap -Type: bool array (min = 0, max = 64) -Syntax: <0|1[,...]> -Description: Force the application to unmap previously mapped buffer memory - before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not - all the applications support this feature. This parameter is - specific for each detected camera. - 0 = do not force memory unmapping - 1 = force memory unmapping (save memory) -Default: 0 -------------------------------------------------------------------------------- -Name: frame_timeout -Type: uint array (min = 0, max = 64) -Syntax: -Description: Timeout for a video frame in seconds. This parameter is - specific for each detected camera. This parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- -Name: debug -Type: ushort -Syntax: -Description: Debugging information level, from 0 to 3: - 0 = none (use carefully) - 1 = critical errors - 2 = significant information - 3 = more verbose messages - Level 3 is useful for testing only, when only one device - is used at the same time. It also shows some more information - about the hardware being detected. This module parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- - - -8. Optional device control through "sysfs" -========================================== -If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled, -it is possible to read and write both the ET61X[12]51 and the image sensor -registers by using the "sysfs" filesystem interface. - -There are four files in the /sys/class/video4linux/videoX directory for each -registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files -control the ET61X[12]51 bridge, while the other two control the sensor chip. -"reg" and "i2c_reg" hold the values of the current register index where the -following reading/writing operations are addressed at through "val" and -"i2c_val". Their use is not intended for end-users, unless you know what you -are doing. Remember that you must be logged in as root before writing to them. - -As an example, suppose we were to want to read the value contained in the -register number 1 of the sensor register table - which is usually the product -identifier - of the camera registered as "/dev/video0": - - [root@localhost #] cd /sys/class/video4linux/video0 - [root@localhost #] echo 1 > i2c_reg - [root@localhost #] cat i2c_val - -Note that if the sensor registers cannot be read, "cat" will fail. -To avoid race conditions, all the I/O accesses to the files are serialized. - - -9. Supported devices -==================== -None of the names of the companies as well as their products will be mentioned -here. They have never collaborated with the author, so no advertising. - -From the point of view of a driver, what unambiguously identify a device are -its vendor and product USB identifiers. Below is a list of known identifiers of -devices mounting the ET61X[12]51 PC camera controllers: - -Vendor ID Product ID ---------- ---------- -0x102c 0x6151 -0x102c 0x6251 -0x102c 0x6253 -0x102c 0x6254 -0x102c 0x6255 -0x102c 0x6256 -0x102c 0x6257 -0x102c 0x6258 -0x102c 0x6259 -0x102c 0x625a -0x102c 0x625b -0x102c 0x625c -0x102c 0x625d -0x102c 0x625e -0x102c 0x625f -0x102c 0x6260 -0x102c 0x6261 -0x102c 0x6262 -0x102c 0x6263 -0x102c 0x6264 -0x102c 0x6265 -0x102c 0x6266 -0x102c 0x6267 -0x102c 0x6268 -0x102c 0x6269 - -The following image sensors are supported: - -Model Manufacturer ------ ------------ -TAS5130D1B Taiwan Advanced Sensor Corporation - -All the available control settings of each image sensor are supported through -the V4L2 interface. - - -10. Notes for V4L2 application developers -========================================= -This driver follows the V4L2 API specifications. In particular, it enforces two -rules: - -- exactly one I/O method, either "mmap" or "read", is associated with each -file descriptor. Once it is selected, the application must close and reopen the -device to switch to the other I/O method; - -- although it is not mandatory, previously mapped buffer memory should always -be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. -The same number of buffers as before will be allocated again to match the size -of the new video frames, so you have to map the buffers again before any I/O -attempts on them. - -Consistently with the hardware limits, this driver also supports image -downscaling with arbitrary scaling factors from 1 and 2 in both directions. -However, the V4L2 API specifications don't correctly define how the scaling -factor can be chosen arbitrarily by the "negotiation" of the "source" and -"target" rectangles. To work around this flaw, we have added the convention -that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the -scaling factor is restored to 1. - -This driver supports two different video formats: the first one is the "8-bit -Sequential Bayer" format and can be used to obtain uncompressed video data -from the device through the current I/O method, while the second one provides -"raw" compressed video data (without frame headers not related to the -compressed data). The current compression quality may vary from 0 to 1 and can -be selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP -V4L2 ioctl's. - - -11.

See http://xirlinkwebcam.sourceforge.net, -http://www.ibmpccamera.com, or http://www.c-itnow.com/ for details and pictures. - -This very chipset ("X Chip", as marked at the factory) -is used in several other cameras, and they are supported -as well: - -- IBM NetCamera -- Veo Stingray - -The Linux driver was developed with camera with following -model number (or FCC ID): KSX-XVP510. This camera has three -interfaces, each with one endpoint (control, iso, iso). This -type of cameras is referred to as "model 1". These cameras are -no longer manufactured. - -Xirlink now manufactures new cameras which are somewhat different. -In particular, following models [FCC ID] belong to that category: - -XVP300 [KSX-X9903] -XVP600 [KSX-X9902] -XVP610 [KSX-X9902] - -(see http://www.xirlink.com/ibmpccamera/ for updates, they refer -to these new cameras by Windows driver dated 12-27-99, v3005 BETA) -These cameras have two interfaces, one endpoint in each (iso, bulk). -Such type of cameras is referred to as "model 2". They are supported -(with exception of 352x288 native mode). - -Some IBM NetCameras (Model 4) are made to generate only compressed -video streams. This is great for performance, but unfortunately -nobody knows how to decompress the stream :-( Therefore, these -cameras are *unsupported* and if you try to use one of those, all -you get is random colored horizontal streaks, not the image! -If you have one of those cameras, you probably should return it -to the store and get something that is supported. - -Tell me more about all that "model" business --------------------------------------------- - -I just invented model numbers to uniquely identify flavors of the -hardware/firmware that were sold. It was very confusing to use -brand names or some other internal numbering schemes. So I found -by experimentation that all Xirlink chipsets fall into four big -classes, and I called them "models". Each model is programmed in -its own way, and each model sends back the video in its own way. - -Quirks of Model 2 cameras: -------------------------- - -Model 2 does not have hardware contrast control. Corresponding V4L -control is implemented in software, which is not very nice to your -CPU, but at least it works. - -This driver provides 352x288 mode by switching the camera into -quasi-352x288 RGB mode (800 Kbits per frame) essentially limiting -this mode to 10 frames per second or less, in ideal conditions on -the bus (USB is shared, after all). The frame rate -has to be programmed very conservatively. Additional concern is that -frame rate depends on brightness setting; therefore the picture can -be good at one brightness and broken at another! I did not want to fix -the frame rate at slowest setting, but I had to move it pretty much down -the scale (so that framerate option barely matters). I also noticed that -camera after first powering up produces frames slightly faster than during -consecutive uses. All this means that if you use 352x288 (which is -default), be warned - you may encounter broken picture on first connect; -try to adjust brightness - brighter image is slower, so USB will be able -to send all data. However if you regularly use Model 2 cameras you may -prefer 176x144 which makes perfectly good I420, with no scaling and -lesser demands on USB (300 Kbits per second, or 26 frames per second). - -Another strange effect of 352x288 mode is the fine vertical grid visible -on some colored surfaces. I am sure it is caused by me not understanding -what the camera is trying to say. Blame trade secrets for that. - -The camera that I had also has a hardware quirk: if disconnected, -it needs few minutes to "relax" before it can be plugged in again -(poorly designed USB processor reset circuit?) - -[Veo Stingray with Product ID 0x800C is also Model 2, but I haven't -observed this particular flaw in it.] - -Model 2 camera can be programmed for very high sensitivity (even starlight -may be enough), this makes it convenient for tinkering with. The driver -code has enough comments to help a programmer to tweak the camera -as s/he feels necessary. - -WHAT YOU NEED: - -- A supported IBM PC (C-it) camera (model 1 or 2) - -- A Linux box with USB support (2.3/2.4; 2.2 w/backport may work) - -- A Video4Linux compatible frame grabber program such as xawtv. - -HOW TO COMPILE THE DRIVER: - -You need to compile the driver only if you are a developer -or if you want to make changes to the code. Most distributions -precompile all modules, so you can go directly to the next -section "HOW TO USE THE DRIVER". - -The ibmcam driver uses usbvideo helper library (module), -so if you are studying the ibmcam code you will be led there. - -The driver itself consists of only one file in usb/ directory: -ibmcam.c. This file is included into the Linux kernel build -process if you configure the kernel for CONFIG_USB_IBMCAM. -Run "make xconfig" and in USB section you will find the IBM -camera driver. Select it, save the configuration and recompile. - -HOW TO USE THE DRIVER: - -I recommend to compile driver as a module. This gives you an -easier access to its configuration. The camera has many more -settings than V4L can operate, so some settings are done using -module options. - -To begin with, on most modern Linux distributions the driver -will be automatically loaded whenever you plug the supported -camera in. Therefore, you don't need to do anything. However -if you want to experiment with some module parameters then -you can load and unload the driver manually, with camera -plugged in or unplugged. - -Typically module is installed with command 'modprobe', like this: - -# modprobe ibmcam framerate=1 - -Alternatively you can use 'insmod' in similar fashion: - -# insmod /lib/modules/2.x.y/usb/ibmcam.o framerate=1 - -Module can be inserted with camera connected or disconnected. - -The driver can have options, though some defaults are provided. - -Driver options: (* indicates that option is model-dependent) - -Name Type Range [default] Example --------------- -------------- -------------- ------------------ -debug Integer 0-9 [0] debug=1 -flags Integer 0-0xFF [0] flags=0x0d -framerate Integer 0-6 [2] framerate=1 -hue_correction Integer 0-255 [128] hue_correction=115 -init_brightness Integer 0-255 [128] init_brightness=100 -init_contrast Integer 0-255 [192] init_contrast=200 -init_color Integer 0-255 [128] init_color=130 -init_hue Integer 0-255 [128] init_hue=115 -lighting Integer 0-2* [1] lighting=2 -sharpness Integer 0-6* [4] sharpness=3 -size Integer 0-2* [2] size=1 - -Options for Model 2 only: - -Name Type Range [default] Example --------------- -------------- -------------- ------------------ -init_model2_rg Integer 0..255 [0x70] init_model2_rg=128 -init_model2_rg2 Integer 0..255 [0x2f] init_model2_rg2=50 -init_model2_sat Integer 0..255 [0x34] init_model2_sat=65 -init_model2_yb Integer 0..255 [0xa0] init_model2_yb=200 - -debug You don't need this option unless you are a developer. - If you are a developer then you will see in the code - what values do what. 0=off. - -flags This is a bit mask, and you can combine any number of - bits to produce what you want. Usually you don't want - any of extra features this option provides: - - FLAGS_RETRY_VIDIOCSYNC 1 This bit allows to retry failed - VIDIOCSYNC ioctls without failing. - Will work with xawtv, will not - with xrealproducer. Default is - not set. - FLAGS_MONOCHROME 2 Activates monochrome (b/w) mode. - FLAGS_DISPLAY_HINTS 4 Shows colored pixels which have - magic meaning to developers. - FLAGS_OVERLAY_STATS 8 Shows tiny numbers on screen, - useful only for debugging. - FLAGS_FORCE_TESTPATTERN 16 Shows blue screen with numbers. - FLAGS_SEPARATE_FRAMES 32 Shows each frame separately, as - it was received from the camera. - Default (not set) is to mix the - preceding frame in to compensate - for occasional loss of Isoc data - on high frame rates. - FLAGS_CLEAN_FRAMES 64 Forces "cleanup" of each frame - prior to use; relevant only if - FLAGS_SEPARATE_FRAMES is set. - Default is not to clean frames, - this is a little faster but may - produce flicker if frame rate is - too high and Isoc data gets lost. - FLAGS_NO_DECODING 128 This flag turns the video stream - decoder off, and dumps the raw - Isoc data from the camera into - the reading process. Useful to - developers, but not to users. - -framerate This setting controls frame rate of the camera. This is - an approximate setting (in terms of "worst" ... "best") - because camera changes frame rate depending on amount - of light available. Setting 0 is slowest, 6 is fastest. - Beware - fast settings are very demanding and may not - work well with all video sizes. Be conservative. - -hue_correction This highly optional setting allows to adjust the - hue of the image in a way slightly different from - what usual "hue" control does. Both controls affect - YUV colorspace: regular "hue" control adjusts only - U component, and this "hue_correction" option similarly - adjusts only V component. However usually it is enough - to tweak only U or V to compensate for colored light or - color temperature; this option simply allows more - complicated correction when and if it is necessary. - -init_brightness These settings specify _initial_ values which will be -init_contrast used to set up the camera. If your V4L application has -init_color its own controls to adjust the picture then these -init_hue controls will be used too. These options allow you to - preconfigure the camera when it gets connected, before - any V4L application connects to it. Good for webcams. - -init_model2_rg These initial settings alter color balance of the -init_model2_rg2 camera on hardware level. All four settings may be used -init_model2_sat to tune the camera to specific lighting conditions. These -init_model2_yb settings only apply to Model 2 cameras. - -lighting This option selects one of three hardware-defined - photosensitivity settings of the camera. 0=bright light, - 1=Medium (default), 2=Low light. This setting affects - frame rate: the dimmer the lighting the lower the frame - rate (because longer exposition time is needed). The - Model 2 cameras allow values more than 2 for this option, - thus enabling extremely high sensitivity at cost of frame - rate, color saturation and imaging sensor noise. - -sharpness This option controls smoothing (noise reduction) - made by camera. Setting 0 is most smooth, setting 6 - is most sharp. Be aware that CMOS sensor used in the - camera is pretty noisy, so if you choose 6 you will - be greeted with "snowy" image. Default is 4. Model 2 - cameras do not support this feature. - -size This setting chooses one of several image sizes that are - supported by this driver. Cameras may support more, but - it's difficult to reverse-engineer all formats. - Following video sizes are supported: - - size=0 128x96 (Model 1 only) - size=1 160x120 - size=2 176x144 - size=3 320x240 (Model 2 only) - size=4 352x240 (Model 2 only) - size=5 352x288 - size=6 640x480 (Model 3 only) - - The 352x288 is the native size of the Model 1 sensor - array, so it's the best resolution the camera can - yield. The best resolution of Model 2 is 176x144, and - larger images are produced by stretching the bitmap. - Model 3 has sensor with 640x480 grid, and it works too, - but the frame rate will be exceptionally low (1-2 FPS); - it may be still OK for some applications, like security. - Choose the image size you need.

This feature is not yet implemented. - - NAME: autoexp - TYPE: integer (Boolean) - DEFAULT: 1 - DESC: Auto Exposure Control enable. This feature is not yet implemented. - - NAME: debug - TYPE: integer (0-6) - DEFAULT: 3 - DESC: Sets the threshold for printing debug messages. The higher the value, - the more is printed. The levels are cumulative, and are as follows: - 0=no debug messages - 1=init/detection/unload and other significant messages - 2=some warning messages - 3=config/control function calls - 4=most function calls and data parsing messages - 5=highly repetitive mesgs - - NAME: snapshot - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Set to 1 to enable snapshot mode. read()/VIDIOCSYNC will block until - the snapshot button is pressed. Note: enabling this mode disables - /proc/video/ov511//button - - NAME: cams - TYPE: integer (1-4 for OV511, 1-31 for OV511+) - DEFAULT: 1 - DESC: Number of cameras allowed to stream simultaneously on a single bus. - Values higher than 1 reduce the data rate of each camera, allowing two - or more to be used at once. If you have a complicated setup involving - both OV511 and OV511+ cameras, trial-and-error may be necessary for - finding the optimum setting. - - NAME: compress - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Set this to 1 to turn on the camera's compression engine. This can - potentially increase the frame rate at the expense of quality, if you - have a fast CPU. You must load the proper compression module for your - camera before starting your application (ov511_decomp or ov518_decomp). - - NAME: testpat - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: This configures the camera's sensor to transmit a colored test-pattern - instead of an image. This does not work correctly yet. - - NAME: dumppix - TYPE: integer (0-2) - DEFAULT: 0 - DESC: Dumps raw pixel data and skips post-processing and format conversion. - It is for debugging purposes only. Options are: - 0: Disable (default) - 1: Dump raw data from camera, excluding headers and trailers - 2: Dumps data exactly as received from camera - - NAME: led - TYPE: integer (0-2) - DEFAULT: 1 (Always on) - DESC: Controls whether the LED (the little light) on the front of the camera - is always off (0), always on (1), or only on when driver is open (2). - This is not supported with the OV511, and might only work with certain - cameras (ones that actually have the LED wired to the control pin, and - not just hard-wired to be on all the time). - - NAME: dump_bridge - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Dumps the bridge (OV511[+] or OV518[+]) register values to the system - log. Only useful for serious debugging/development purposes. - - NAME: dump_sensor - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Dumps the sensor register values to the system log. Only useful for - serious debugging/development purposes. - - NAME: printph - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Setting this to 1 will dump the first 12 bytes of each isoc frame. This - is only useful if you are trying to debug problems with the isoc data - stream (i.e.: camera initializes, but vidcat hangs until Ctrl-C). Be - warned that this dumps a large number of messages to your kernel log. - - NAME: phy, phuv, pvy, pvuv, qhy, qhuv, qvy, qvuv - TYPE: integer (0-63 for phy and phuv, 0-255 for rest) - DEFAULT: OV511 default values - DESC: These are registers 70h - 77h of the OV511, which control the - prediction ranges and quantization thresholds of the compressor, for - the Y and UV channels in the horizontal and vertical directions. See - the OV511 or OV511+ data sheet for more detailed descriptions. These - normally do not need to be changed. - - NAME: lightfreq - TYPE: integer (0, 50, or 60) - DEFAULT: 0 (use sensor default) - DESC: Sets the sensor to match your lighting frequency. This can reduce the - appearance of "banding", i.e. horizontal lines or waves of light and - dark that are often caused by artificial lighting. Valid values are: - 0 - Use default (depends on sensor, most likely 60 Hz) - 50 - For European and Asian 50 Hz power - 60 - For American 60 Hz power - - NAME: bandingfilter - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Enables the sensor´s banding filter exposure algorithm. This reduces - or stabilizes the "banding" caused by some artificial light sources - (especially fluorescent). You might have to set lightfreq correctly for - this to work right. As an added bonus, this sometimes makes it - possible to capture your monitor´s output. - - NAME: fastset - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Allows picture settings (brightness, contrast, color, and hue) to take - effect immediately, even in the middle of a frame. This reduces the - time to change settings, but can ruin frames during the change. Only - affects OmniVision sensors. - - NAME: force_palette - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Forces the palette (color format) to a specific value. If an - application requests a different palette, it will be rejected, thereby - forcing it to try others until it succeeds. This is useful for forcing - greyscale mode with a color camera, for example. Supported modes are: - 0 (Allows all the following formats) - 1 VIDEO_PALETTE_GREY (Linear greyscale) - 10 VIDEO_PALETTE_YUV420 (YUV 4:2:0 Planar) - 15 VIDEO_PALETTE_YUV420P (YUV 4:2:0 Planar, same as 10) - - NAME: backlight - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Setting this flag changes the exposure algorithm for OmniVision sensors - such that objects in the camera's view (i.e. your head) can be clearly - seen when they are illuminated from behind. It reduces or eliminates - the sensor's auto-exposure function, so it should only be used when - needed. Additionally, it is only supported with the OV6620 and OV7620. - - NAME: unit_video - TYPE: Up to 16 comma-separated integers - DEFAULT: 0,0,0... (automatically assign the next available minor(s)) - DESC: You can specify up to 16 minor numbers to be assigned to ov511 devices. - For example, "unit_video=1,3" will make the driver use /dev/video1 and - /dev/video3 for the first two devices it detects. Additional devices - will be assigned automatically starting at the first available device - node (/dev/video0 in this case). Note that you cannot specify 0 as a - minor number. This feature requires kernel version 2.4.5 or higher. - - NAME: remove_zeros - TYPE: integer (Boolean) - DEFAULT: 0 (do not skip any incoming data) - DESC: Setting this to 1 will remove zero-padding from incoming data. This - will compensate for the blocks of corruption that can appear when the - camera cannot keep up with the speed of the USB bus (eg. at low frame - resolutions). This feature is always enabled when compression is on. - - NAME: mirror - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Setting this to 1 will reverse ("mirror") the image horizontally. This - might be necessary if your camera has a custom lens assembly. This has - no effect with video capture devices. - - NAME: ov518_color - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Enable OV518 color support. This is off by default since it doesn't - work most of the time. If you want to try it, you must also load - ov518_decomp with the "nouv=0" parameter. If you get improper colors or - diagonal lines through the image, restart your video app and try again. - Repeat as necessary. - -WORKING FEATURES: - o Color streaming/capture at most widths and heights that are multiples of 8. - o Monochrome (use force_palette=1 to enable) - o Setting/getting of saturation, contrast, brightness, and hue (only some of - them work the OV7620 and OV7620AE) - o /proc status reporting - o SAA7111A video capture support at 320x240 and 640x480 - o Compression support - o SMP compatibility - -HOW TO CONTACT ME: - -You can email me at mark@alpha.dyndns.org .

Overview -=========== -This driver supports the video streaming capabilities of the devices mounting -Winbond W9967CF and Winbond W9968CF JPEG USB Dual Mode Camera Chips. OV681 -based cameras should be supported as well. - -The driver is divided into two modules: the basic one, "w9968cf", is needed for -the supported devices to work; the second one, "w9968cf-vpp", is an optional -module, which provides some useful video post-processing functions like video -decoding, up-scaling and colour conversions. - -Note that the official kernels do neither include nor support the second -module for performance purposes. Therefore, it is always recommended to -download and install the latest and complete release of the driver, -replacing the existing one, if present. - -The latest and full-featured version of the W996[87]CF driver can be found at: -http://www.linux-projects.org. Please refer to the documentation included in -that package, if you are going to use it. - -Up to 32 cameras can be handled at the same time. They can be connected and -disconnected from the host many times without turning off the computer, if -your system supports the hotplug facility. - -To change the default settings for each camera, many parameters can be passed -through command line when the module is loaded into memory. - -The driver relies on the Video4Linux, USB and I2C core modules. It has been -designed to run properly on SMP systems as well. An additional module, -"ovcamchip", is mandatory; it provides support for some OmniVision image -sensors connected to the W996[87]CF chips; if found in the system, the module -will be automatically loaded by default (provided that the kernel has been -compiled with the automatic module loading option). - - -5. Supported devices -==================== -At the moment, known W996[87]CF and OV681 based devices are: -- Aroma Digi Pen VGA Dual Mode ADG-5000 (unknown image sensor) -- AVerMedia AVerTV USB (SAA7111A, Philips FI1216Mk2 tuner, PT2313L audio chip) -- Creative Labs Video Blaster WebCam Go (OmniVision OV7610 sensor) -- Creative Labs Video Blaster WebCam Go Plus (OmniVision OV7620 sensor) -- Lebon LDC-035A (unknown image sensor) -- Ezonics EZ-802 EZMega Cam (OmniVision OV8610C sensor) -- OmniVision OV8610-EDE (OmniVision OV8610 sensor) -- OPCOM Digi Pen VGA Dual Mode Pen Camera (unknown image sensor) -- Pretec Digi Pen-II (OmniVision OV7620 sensor) -- Pretec DigiPen-480 (OmniVision OV8610 sensor) - -If you know any other W996[87]CF or OV681 based cameras, please contact me. - -The list above does not imply that all those devices work with this driver: up -until now only webcams that have an image sensor supported by the "ovcamchip" -module work. Kernel messages will always tell you whether this is case. - -Possible external microcontrollers of those webcams are not supported: this -means that still images cannot be downloaded from the device memory. - -Furthermore, it's worth to note that I was only able to run tests on my -"Creative Labs Video Blaster WebCam Go". Donations of other models, for -additional testing and full support, would be much appreciated. - - -6. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux, USB -and I2C, and the "ovcamchip" module for the image sensor. Make sure you are not -actually using any external "ovcamchip" module, given that the W996[87]CF -driver depends on the version of the module present in the official kernels. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - - # I2C support - # - CONFIG_I2C=m - -The I2C core module can be compiled statically in the kernel as well. - - # OmniVision Camera Chip support - # - CONFIG_VIDEO_OVCAMCHIP=m - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, only one of the modules -below is necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_W9968CF=m - - -7. Module loading -================= -To use the driver, it is necessary to load the "w9968cf" module into memory -after every other module required. - -Loading can be done this way, from root: - - [root@localhost home]# modprobe usbcore - [root@localhost home]# modprobe i2c-core - [root@localhost home]# modprobe videodev - [root@localhost home]# modprobe w9968cf - -At this point the pertinent devices should be recognized: "dmesg" can be used -to analyze kernel messages: - - [user@localhost home]$ dmesg - -There are a lot of parameters the module can use to change the default -settings for each device. To list every possible parameter with a brief -explanation about them and which syntax to use, it is recommended to run the -"modinfo" command: - - [root@locahost home]# modinfo w9968cf - - -8.

Overview and features -======================== -This driver supports the video interface of the devices mounting the ZC0301 or -ZC0301P Image Processors and Control Chips. - -The driver relies on the Video4Linux2 and USB core modules. It has been -designed to run properly on SMP systems as well. - -The latest version of the ZC0301[P] driver can be found at the following URL: -http://www.linux-projects.org/ - -Some of the features of the driver are: - -- full compliance with the Video4Linux2 API (see also "Notes for V4L2 - application developers" paragraph); -- available mmap or read/poll methods for video streaming through isochronous - data transfers; -- automatic detection of image sensor; -- video format is standard JPEG; -- dynamic driver control thanks to various module parameters (see "Module - parameters" paragraph); -- up to 64 cameras can be handled at the same time; they can be connected and - disconnected from the host many times without turning off the computer, if - the system supports hotplugging; - - -5. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux and -USB. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, the modules below are -necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -The ZC0301 controller also provides a built-in microphone interface. It is -supported by the USB Audio driver thanks to the ALSA API: - - # Sound - # - CONFIG_SOUND=y - - # Advanced Linux Sound Architecture - # - CONFIG_SND=m - - # USB devices - # - CONFIG_SND_USB_AUDIO=m - -And finally: - - # V4L USB devices - # - CONFIG_USB_ZC0301=m - - -6. Module loading -================= -To use the driver, it is necessary to load the "zc0301" module into memory -after every other module required: "videodev", "v4l2_common", "compat_ioctl32", -"usbcore" and, depending on the USB host controller you have, "ehci-hcd", -"uhci-hcd" or "ohci-hcd". - -Loading can be done as shown below: - - [root@localhost home]# modprobe zc0301 - -At this point the devices should be recognized. You can invoke "dmesg" to -analyze kernel messages and verify that the loading process has gone well: - - [user@localhost home]$ dmesg - - -7. Module parameters -==================== -Module parameters are listed below: -------------------------------------------------------------------------------- -Name: video_nr -Type: short array (min = 0, max = 64) -Syntax: <-1|n[,...]> -Description: Specify V4L2 minor mode number: - -1 = use next available - n = use minor number n - You can specify up to 64 cameras this way. - For example: - video_nr=-1,2,-1 would assign minor number 2 to the second - registered camera and use auto for the first one and for every - other camera. -Default: -1 -------------------------------------------------------------------------------- -Name: force_munmap -Type: bool array (min = 0, max = 64) -Syntax: <0|1[,...]> -Description: Force the application to unmap previously mapped buffer memory - before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's.

This parameter is - specific for each detected camera. - 0 = do not force memory unmapping - 1 = force memory unmapping (save memory) -Default: 0 -------------------------------------------------------------------------------- -Name: frame_timeout -Type: uint array (min = 0, max = 64) -Syntax: -Description: Timeout for a video frame in seconds. This parameter is - specific for each detected camera. This parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- -Name: debug -Type: ushort -Syntax: -Description: Debugging information level, from 0 to 3: - 0 = none (use carefully) - 1 = critical errors - 2 = significant information - 3 = more verbose messages - Level 3 is useful for testing only, when only one device - is used at the same time. It also shows some information - about the hardware being detected. This module parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- - - -8. Supported devices -==================== -None of the names of the companies as well as their products will be mentioned -here. They have never collaborated with the author, so no advertising. - -From the point of view of a driver, what unambiguously identify a device are -its vendor and product USB identifiers. Below is a list of known identifiers of -devices mounting the ZC0301 Image Processor and Control Chips: - -Vendor ID Product ID ---------- ---------- -0x041e 0x4017 -0x041e 0x401c -0x041e 0x401e -0x041e 0x401f -0x041e 0x4022 -0x041e 0x4034 -0x041e 0x4035 -0x041e 0x4036 -0x041e 0x403a -0x0458 0x7007 -0x0458 0x700c -0x0458 0x700f -0x046d 0x08ae -0x055f 0xd003 -0x055f 0xd004 -0x0ac8 0x0301 -0x0ac8 0x301b -0x0ac8 0x303b -0x10fd 0x0128 -0x10fd 0x8050 -0x10fd 0x804e - -The list above does not imply that all those devices work with this driver: up -until now only the ones that mount the following image sensors are supported; -kernel messages will always tell you whether this is the case: - -Model Manufacturer ------ ------------ -PAS202BCB PixArt Imaging, Inc. -PB-0330 Photobit Corporation - - -9. Notes for V4L2 application developers -======================================== -This driver follows the V4L2 API specifications. In particular, it enforces two -rules: - -- exactly one I/O method, either "mmap" or "read", is associated with each -file descriptor. Once it is selected, the application must close and reopen the -device to switch to the other I/O method; - -- although it is not mandatory, previously mapped buffer memory should always -be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. -The same number of buffers as before will be allocated again to match the size -of the new video frames, so you have to map the buffers again before any I/O -attempts on them. - - -10. Contact information -======================= -The author may be contacted by e-mail at . - -GPG/PGP encrypted e-mail's are accepted. The GPG key ID of the author is -'FCE635A4'; the public 1024-bit key should be available at any keyserver; -the fingerprint is: '88E8 F32F 7244 68BA 3958 5D40 99DA 5D2A FCE6 35A4'. - - -11.

The functionality includes all the standard v4l2 interfaces including streaming. The video node interface can be used both as an input and output node for both continuous and single shot modes. Also supports dv_presets to include HD modes, wth support for both user pointer IO and mmap. The buffering mechanism is based on videobuf2 interface.

ISIF is responsible for capturing video data both in raw bayer format on sync seperate signals and YUV through BT656/1120 interfaces. ISIF is exposed as a subdev for the vpfe driver and allows users to use the driver through standard media controller interface.

driver based on media framework Add the video resizer driver with the v4l2 media controller framework which takes care of resizing the video frames with both up-scaling downscaling facility. The driver supports both continuous and single shot operations.The driver supports resizer as a subdevice and a media entity. It has support for 2 resizers - resizerA and resizerB.

To differentiate between this platforms venc_type/vpbe_type was passed as part of platform data which was incorrect. The correct way to differentiate to handle this case is by passing different platform names. This patch creates platform_device_id[] array supporting different platforms and assigns id_table to the platform driver, and finally in the probe gets the actual device by using platform_get_device_id() and gets the appropriate driver data for that platform. Taking this approach will also make the DT transition easier.

So when we fall through to the 'err_gpio_request' label further down and call rc_free_device(rcdev) then that's a double free. Fix that by moving 'rcdev = NULL' from after the call to rc_free_device() to after rc_unregister_device(). That fixes the problem since rc_free_device() just does nothing if passed NULL and there's no further use of 'rcdev' after the call to rc_free_device() so it's not needed there.

For example for 8 devices and 8 simple programs running, where each captures YUY2 640x480 and displays it to X via SDL, profile timing is as follows: # cmdline : /home/kirr/local/perf/bin/perf record -g -a sleep 20 # Samples: 82K of event 'cycles' # Event count (approx.): 31551930117 # # Overhead Command Shared Object Symbol # ........ ............... .................... # 49.48% vivi-* [vivi] [k] gen_twopix 10.79% vivi-* [kernel.kallsyms] [k] memcpy 10.02% rawv libc-2.13.so [.] __memcpy_ssse3 8.35% vivi-* [vivi] [k] gen_text.constprop.6 5.06% Xorg [unknown] [.] 0xa73015f8 2.32% rawv [vivi] [k] gen_twopix 1.22% rawv [vivi] [k] precalculate_line 1.20% vivi-* [vivi] [k] vivi_fillbuff (rawv is display program, vivi-* is a combination of vivi-000 through vivi-007) so a lot of time is spent in gen_twopix() which as the follwing call-graph profile shows ... 49.48% vivi-* [vivi] [k] gen_twopix | --- gen_twopix | |--96.30%-- gen_text.constprop.6 | vivi_fillbuff | vivi_thread | kthread | ret_from_kernel_thread | --3.70%-- vivi_fillbuff vivi_thread kthread ret_from_kernel_thread ... is called mostly from gen_text(). If we'll look at gen_text(), in the inner loop, we'll see if (chr & (1 << (7 - i))) gen_twopix(dev, pos + j * dev->pixelsize, WHITE, (x+y) & 1); else gen_twopix(dev, pos + j * dev->pixelsize, TEXT_BLACK, (x+y) & 1); which calls gen_twopix() for every character pixel, and that is very expensive, because gen_twopix() branches several times. Now, let's note, that we operate on only two colors - WHITE and TEXT_BLACK, and that pixel for that colors could be precomputed and gen_twopix() moved out of the inner loop. Also note, that for black and white colors even/odd does not make a difference for all supported pixel formats, so we could stop doing that `odd` gen_twopix() parameter game. So the first thing we are doing here is 1) moving gen_twopix() calls out of gen_text() into vivi_fillbuff(), to pregenerate black and white colors, just before printing starts. what we have next is that gen_text's font rendering loop, even with gen_twopix() calls moved out, was inefficient and branchy, so let's 2) rewrite gen_text() loop so it uses less variables + unroll char horizontal-rendering loop + instantiate 3 code paths for pixelsizes 2,3 and 4 so that in all inner loops we don't have to branch or make indirections (*). Done all above reworks, for gen_text() we get nice, non-branchy streamlined code (showing loop for pixelsize=2): ? cmp $0x2,%eax ? ? jne 26 ? mov -0x18(%ebp),%eax ? mov -0x20(%ebp),%edi ? imul -0x20(%ebp),%eax ? movzwl 0x3ffc(%ebx),%esi 0,08 ? movzwl 0x4000(%ebx),%ecx 0,04 ? add %edi,%edi ? mov 0x0,%ebx 0,51 ? mov %edi,-0x1c(%ebp) ? mov %ebx,-0x14(%ebp) ? movl $0x0,-0x10(%ebp) ? lea 0x20(%edx,%eax,2),%eax ? mov %eax,-0x18(%ebp) ? xchg %ax,%ax 0,04 ? a0: mov 0x8(%ebp),%ebx ? mov -0x18(%ebp),%eax 0,04 ? movzbl (%ebx),%edx 0,16 ? test %dl,%dl 0,04 ? ? je 128 0,08 ? lea 0x0(%esi),%esi 1,61 ? b0:???shl $0x4,%edx 1,02 ? ? mov -0x14(%ebp),%edi 2,04 ? ? add -0x10(%ebp),%edx 2,24 ? ? lea 0x1(%ebx),%ebx 0,27 ? ? movzbl (%edi,%edx,1),%edx 9,92 ? ? mov %esi,%edi 0,39 ? ? test %dl,%dl 2,04 ? ? cmovns %ecx,%edi 4,63 ? ? test $0x40,%dl 0,55 ? ? mov %di,(%eax) 3,76 ? ? mov %esi,%edi 0,71 ? ? cmove %ecx,%edi 3,41 ? ? test $0x20,%dl 0,75 ? ? mov %di,0x2(%eax) 2,43 ? ? mov %esi,%edi 0,59 ? ? cmove %ecx,%edi 4,59 ? ? test $0x10,%dl 0,67 ? ? mov %di,0x4(%eax) 2,55 ? ? mov %esi,%edi 0,78 ? ? cmove %ecx,%edi 4,31 ? ? test $0x8,%dl 0,67 ? ? mov %di,0x6(%eax) 5,76 ? ? mov %esi,%edi 1,80 ? ? cmove %ecx,%edi 4,20 ? ? test $0x4,%dl 0,86 ? ? mov %di,0x8(%eax) 2,98 ? ? mov %esi,%edi 1,37 ? ? cmove %ecx,%edi 4,67 ? ? test $0x2,%dl 0,20 ? ? mov %di,0xa(%eax) 2,78 ? ? mov %esi,%edi 0,75 ? ? cmove %ecx,%edi 3,92 ? ? and $0x1,%edx 0,75 ? ? mov %esi,%edx 2,59 ? ? mov %di,0xc(%eax) 0,59 ? ? cmove %ecx,%edx 3,10 ? ? mov %dx,0xe(%eax) 2,39 ? ? add $0x10,%eax 0,51 ? ? movzbl (%ebx),%edx 2,86 ? ? test %dl,%dl 2,31 ? ???jne b0 0,04 ?128: addl $0x1,-0x10(%ebp) 4,00 ? mov -0x1c(%ebp),%eax 0,04 ? add %eax,-0x18(%ebp) 0,08 ? cmpl $0x10,-0x10(%ebp) ? ? jne a0 which almost goes away from the profile: # cmdline : /home/kirr/local/perf/bin/perf record -g -a sleep 20 # Samples: 49K of event 'cycles' # Event count (approx.): 16799780016 # # Overhead Command Shared Object Symbol # ........ ............... .................... # 27.51% rawv libc-2.13.so [.] __memcpy_ssse3 23.77% vivi-* [kernel.kallsyms] [k] memcpy 9.96% Xorg [unknown] [.] 0xa76f5e12 4.94% vivi-* [vivi] [k] gen_text.constprop.6 4.44% rawv [vivi] [k] gen_twopix 3.17% vivi-* [vivi] [k] vivi_fillbuff 2.45% rawv [vivi] [k] precalculate_line 1.20% swapper [kernel.kallsyms] [k] read_hpet i.e. gen_twopix() overhead dropped from 49% to 4% and gen_text() loops from ~8% to ~4%, and overal cycles count dropped from 31551930117 to 16799780016 which is ~1.9x whole workload speedup. (*) for RGB24 rendering I've introduced x24, which could be thought as synthetic u24 for simplifying the code. That's done because for memcpy used for conditional assignment, gcc generates suboptimal code with more indirections. Fortunately, in C struct assignment is builtin and that's all we need from pixeltype for font rendering.

Now, the labels are named after the cleanup action they'll perform (first), based on how the winbond-cir driver does it. This makes the code a bit more clear and makes changes in the ordering of labels easier to review. This change is applied only to the rc drivers that do significant cleanup in their probe functions: ati-remote, ene-ir, fintek-cir, gpio-ir-recv, ite-cir, nuvoton-cir. This commit should not change any code, it just renames goto labels.

It seems this crash is very reproducible (just bombard the receiver with IR signals during module load), probably because when request_irq is called, any pending intterupt is handled immediately, before request_irq returns and rdev can be set. This same crash was supposed to be fixed by commit 9ef449c6b31bb6a8e6dedc24de475a3b8c79be20 ("[media] rc: Postpone ISR registration"), but the crash was still observed on the nuvoton-cir driver. This commit was tested on nuvoton-cir only.

This crash has not been observed in practice, but there should be a very small window where it could occur. Since ir_raw_event_store_with_filter checks if rdev->raw is not NULL before using it, this bug is not triggered if the request_irq triggers a pending irq directly (since rdev->raw will still be NULL then).

This happens only for the second and all following lines in the packet. The reason why this bug doesn't cause image corruption with my test device (SilverCrest Webcam 1.3 MPix) is, that this device never sends any packets that cross the end of a line. I don't know if all devices behave like this, so this patch should be considered for stable. With the upcoming patches to add support for USB bulk transfers, em28xx_copy_video will be called once per URB, which will always trigger this bug.

charset=UTF-8 Content-Transfer-Encoding: 8bit em28xx_urb_data_copy_vbi() is actually an extended version of em28xx_urb_data_copy(). With the preceding fixes and improvements, it works fine with both, vbi and non-vbi data streams without performance impacts. So rename em28xx_urb_data_copy_vbi() to em28xx_urb_data_copy(), delete the the old implementation of em28xx_urb_data_copy() and change the code to use this function for both data stream types. Tested with "SilverCrest 1.3 MPix webcam" (progressive, non-vbi) and "Hauppauge HVR-900 (65008/A1C0)" (interlaced, vbi enabled and disabled).

charset=UTF-8 Content-Transfer-Encoding: 8bit When a new frame header is detected in em28xx_urb_data_copy() and the data packet contains both, VBI data and video data, the prevoius VBI buffer doesn't get finished and is overwritten with the new VBI data. This bug is not triggered with isochronous USB transfers, because the data packetes are much smaller than the VBI data size. But when using USB bulk transfers, the whole data of an URB is treated as single packet, which is usually much larger then the VBI data size. Refactor the VBI data processing code to fix this bug, but also to simplify the code and make it similar to the video data processing code part (which allows further code abstraction/unification in the future). The changes have been tested with device "Hauppauge HVR-900".

The alternative would be to call videobuf_to_vmalloc() for each processed USB data packet (isoc USB transfers => 64 times per URB) in the em28xx_copy_*() functions. With the next commits, the data processing code will be split into functions for serveral reasons: - em28xx_urb_data_copy() is generally way to long, making it less readable - there is code duplication between VBI and video data processing - support for em25xx data processing (uses a different header and frame end signaling mechanism) will be added This would require extensive usage of pointer-pointers, which usually makes the code less readable and prone to bugs. The better solution is to cache the pointer in struct em28xx_buffer. This also improves consistency, because we already track the buffer fill count there.

So, prefer it, if the device is a webcam. Tested with Silvercrest 1.3 Mpixel webcam (em2710) on both bulk and isoc modes. Tested analog with HVR-950 model 65201/A1C0 (em2883), where only ISOC endpoints are available for both DVB and Analog. Tested on Hauppauge WinTV USB 2 (em2840) on both bulk and isoc modes. It should be noticed that enabling bulk mode by default with TV boards is a bad idea; what happens is that, while with ISOC the USB logic will prevent the concurrent usage of two devices that spends more than 100% of the USB2 traffic, it doesn't care with bulk transfers. On my tests, I started two streams, one with a WinTV at 640x480x30fps and the other one with a Silvercrest webcam at 640x480, on a lower fps) both on bulk mode. One of the streams always silently failed.

Only its framerate was hardcoded to NTSC's 30fps, while in my country we usually use PAL (25 fps) and I needed that to precisely simulate bandwidth. That's why here is this patch with ->enum_frameintervals() and ->{g,s}_parm() implemented as suggested by Hans Verkuil which passes v4l2-compliance and manual testing through v4l2-ctl -P / -p . Regarding newly introduced __get_format(u32 pixelformat) I decided not to convert original get_format() to operate on fourcc codes, since >= 3 places in driver need to deal with v4l2_format and otherwise it won't be handy.

Unfortunately, frontend ioctls can be blocked by the frontend thread for several seconds; this leads to unacceptable lock contention. Mitigate that by pushing the mutex from dvb_usercopy down to the individual, device specific ioctls. There are 10 such ioctl functions using dvb_usercopy, either calling it directly, or via the trivial wrapper dvb_generic_ioctl. The following already employ their own locking and look safe: • dvb_demux_ioctl (as per dvb_demux_do_ioctl) • dvb_dvr_ioctl (as per dvb_dvr_do_ioctl) • dvb_osd_ioctl (as per single non-trivial callee) • fdtv_ca_ioctl (as per callees) • dvb_frontend_ioctl The following functions do not, and are thus changed to use a device specific mutex: • dvb_net_ioctl (as per dvb_net_do_ioctl) • dvb_ca_en50221_io_ioctl (as per dvb_ca_en50221_io_do_ioctl) • dvb_video_ioctl • dvb_audio_ioctl • dvb_ca_ioctl Signed-off-by: Nikolaus Schulz Signed-off-by: Michael Krufky Signed-off-by: Mauro Carvalho Chehab --- drivers/media/dvb-core/dvb_ca_en50221.c | 9 +++++ drivers/media/dvb-core/dvb_net.c | 71 ++++++++++++++++++++++----------- drivers/media/dvb-core/dvb_net.h | 1 + drivers/media/dvb-core/dvbdev.c | 2 - drivers/media/pci/ttpci/av7110.c | 2 + drivers/media/pci/ttpci/av7110.h | 2 + drivers/media/pci/ttpci/av7110_av.c | 8 ++++ drivers/media/pci/ttpci/av7110_ca.c | 24 +++++++---- 8 files changed, 87 insertions(+), 32 deletions(-) diff --git a/drivers/media/dvb-core/dvb_ca_en50221.c b/drivers/media/dvb-core/dvb_ca_en50221.c index 9be65a3b931f..190e5e0f48c7 100644 --- a/drivers/media/dvb-core/dvb_ca_en50221.c +++ b/drivers/media/dvb-core/dvb_ca_en50221.c @@ -156,6 +156,9 @@ struct dvb_ca_private { /* Slot to start looking for data to read from in the next user-space read operation */ int next_read_slot;

Rather than try to fix the driver to cope (as has been done by Andy Walls for the cx18 driver), put in a pm_qos_request to limit deep sleep exit latencies. The visible effect of not having this is that seemingly random lines are only partly transferred - if you feed in a static image, you see a portion of the image "flicker" into place.

When the device has an I2C remote, all it needs to do is to call the proper I2C driver (ir-i2c-kbd), passing the proper data to it, and just leave the code. Also, button devices have its own init code that doesn't depend on having an IR or not (as a general rule, they don't have). So, move its init code to fix bugs introduced by earlier patches that prevent them to work.

OTOH, holding .video_lock in soc_camera_open() isn't enough to protect the host during its building of the pipeline, because .video_lock is per soc-camera device. If, e.g. more than one sensor can be attached to a host and the user tries to open both device nodes simultaneously, host's .add() method can be called simultaneously for both sensors. Fix these problems by holding list_lock instead of .host_lock in scan_add_host() and taking it shortly at the beginning of soc_camera_open(), and using .host_lock to protect host's .add() and .remove() operations only.

The deadlock is avoided by always taking the graph mutex first in video node open() or an ioctl, before the video lock is acquired. Reversed order seems impossible, since media device driver's link_notify callback is called with media graph mutex already held. To ensure proper locking order VIDIOC_S_FMT and VIDIOC_TRY_FMT ioctls are not serialized in the v4l2-core and the driver takes care of it itself.

Fortunately, it's easy to fix - just take ->mmap_sem a bit earlier (and don't bother with find_vma() at all if virtp >= PAGE_OFFSET - in that case we don't even look at its result). While we are at it, what prevents VIDIOC_PREPARE_BUF calling v4l_prepare_buf() -> (e.g) vb2_ioctl_prepare_buf() -> vb2_prepare_buf() -> __buf_prepare() -> __qbuf_userptr() -> vb2_vmalloc_get_userptr() -> find_vma(), AFAICS without having taken ->mmap_sem anywhere in process? The code flow is bloody convoluted and depends on a bunch of things done by initialization, so I certainly might've missed something...

Currently, there's no way to report per-layer stats. To address the above issues, adding a new DVBv5-based stats API. While here, correct inner code nomenclature on a few places.

On ISDB-T devices, those reads are done per layer. However, as userspace applications may not be aware of that, add a global measure that will sum the bit errors and bit counts for each layer, storing them into a global value.

This is helpful in situations when range of a control depends on user configurable parameters, e.g. camera sensor absolute exposure time depending on an output image resolution and frame rate. v4l2_ctrl_modify_range() function allows to modify range of an INTEGER, BOOL, MENU, INTEGER_MENU and BITMASK type controls.

The spec specifies that for radio devices only mono and stereo audmodes are valid. If the user specifies another audmode in v4l2_tuner, then that should be mapped to valid audmode. That didn't happen here. Note that tuner drivers might decide to limit the possible audmode even further if it only supports mono. In that case the tuner driver can set audmode to mono. However, that new value wasn't copied back to t->audmode, and that has been fixed as well in this patch.

In case of a configuration where video is captured at the video node exposed by the FIMC-LITE driver there is a following video pipeline: sensor -> MIPI-CSIS.n -> FIMC-LITE.n subdev -> FIMC-LITE.n video node In this situation s_stream() handler of the FIMC-LITE.n is called back from within VIDIOC_STREAMON/OFF ioctl of the FIMC-LITE.n video node, through vb2_stream_on/off(), start/stop_streaming and fimc_pipeline_call(set_stream). The fimc->lock mutex is already held then, before invoking vidioc_streamon/off. So it must not be taken again in the s_stream() callback in this case, to avoid a deadlock. This patch makes fimc->out_path atomic_t so the mutex don't need to be taken in the FIMC-LITE subdev s_stream() callback in the DMA output case.

Nothing was preventing module from unloading during a call to try_module_get(driver->owner). Instead, we look up a device first and then check for its driver while holding device lock. The platform sub-devices are looked up and registered to the top level driver. When any sub-device is not yet initialized and ready the main driver's probe() will be deferred.

Such sensors can be connected through FIMC-LITEn (and MIPI-CSISn) IPs to the ISP, which then feeds image data to the FIMCn IP. Thus there can be two busses associated with an image source (sensor). Rename struct s5p_fimc_isp_info describing external image sensor (video decoder) to struct fimc_source_info to avoid confusion. bus_type is split into fimc_bus_type and sensor_bus_type. The bus type enumeration is extended to include both FIMC Writeback input types. The bus_type enumeration and the data structure name in the board files are modified according to the above changes.

Some private controls have been replaced with standardized controls (SHARPNESS and JPEGQUAL). The AGC control looks like it can be replaced by the AUTOGAIN control, but it isn't a boolean so I do not know how to interpret it. The FRAMERATE control looks like it can be replaced by S_PARM, but again, without knowing how to interpret it I decided to leave it alone.

This also fixed a nasty issue where opening the radio would set dev->input to 5 for no good reason. This was never set back to a valid TV input after closing the radio device, thus leaving it at 5 which is out of bounds of the vinput card array.

This might happen in normal conditions when the driver's probing is deferred and then retried.

It is now called at analog streaming start only. This has unveiled a bug that causes USB bulk transfers to fail with all urbs having status -EVOERFLOW. The reason is, that for bulk transfers usb_set_interface() needs to be called even if the previous alt setting was the same (side note: bulk transfers seem to work only with alt=0). While it seems to be NOT necessary for isoc transfers, it's reasonable to just call usb_set_interface() unconditionally in em28xx_set_alternate(). Also add a comment that explains the issue to prevent regressions in the future.

So far only the default YUYV format has been verified to work with mt9t111. Limit the driver to only report one supported format with mt9t111 until more formats are implemented.

However, some of these devices (like mine) come with a different USB PID 0x3009 instead of 0x3006. There have already been patches simply overwriting the USB PID in dvb-usb-ids.h. Of course these patches were rejected because they would have disabled the 0x3006 PID. This new patch adds the 0x3009 PID to dvb-usb-ids.h, and adds references to it within the ttusb2.c driver. PID 0x3006 devices will continue to work. The only difference between the two hardware models seems to be the EEPROM chip. In fact, Windows BDA driver names the 0x3009 device with a "(8 kB EEPROM)" suffix. In spite of that, the 0x3009 device works absolutely flawlessly using the existing ttusb2 driver.
