From 7f1711234e6a21c153e892758d9d82c333ab37ac Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 18 Oct 2007 19:56:47 -0300 Subject: V4L/DVB (6384): Replace TDA9887_SET_CONFIG by TUNER_SET_CONFIG Currently, the only tuner-specific device that allows special configurations is tda9887. However, tea5767 also may require some special configurations (for example, to specify a different Xtal freq). This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl (TUNER_SET_CONFIG). The newer one allows specifying what tuner is appliable to a configuration set, and allows an arbitrary configuration struct.

Before the patch, the driver were assuming the more common configuration. However, some newer cards, like MSI @nyware Master requires other configurations, like de-activating a gpio port and changing chip Xtal. This patch adds the capability of altering device configuration at runtime. This may also be used later to activate some features like auto-mute when signal is weak.

Basically, radio XTAL uses a different frequency than the other supported radios. It uses a 13 MHz XTAL. This patch adds the proper radio gpio and tea5767 configurations for the board. Also, with PAL/BG, the board requires some special init for tda9887: port1=0 port2=0 qss=1 Thanks to Serge Kolotylo and MIDImaster for their help on identifying the proper needs for this driver.

The tuner.ko module (tuner-core) will pass commands to tda8290 via the tuner_operations interface. tda8290 will communicate with tda827x via the dvb_frontend interface, while passing a pointer to a private data structure.

We already have a method to control such i2c gates when they are controlled by the digital demodulator, but in some hybrid designs, there may be an i2c gate controlled by each demodulator. For example, when in analog tuning mode, one would access the tuner by opening the i2c gate controlled by the analog demodulator, while when in digital tuning mode, one would access the tuner by opening the i2c gate controlled by the digital demodulator.

The basic problem is that it selects certain drivers, but does not depend on the dependencies of those drivers. See http://article.gmane.org/gmane.comp.video.video4linux/35072 Using the Kconfig file also has some annoyances. For instance one can't turn off AV7110 support unless you go down several options and first turn off budget-patch support. Normally user selectable drivers are not forced on like this. The "AV7110 cards with Budget Patch" option is disabled if "Budget cards" isn't on. Normally a driver appears nested under a driver it depends on, but since drivers that don't depend on "Budget cards" are between the two options, the config programs can't display the tree correctly. The Makefile has an issue too. Some modules, ttpci-eeprom and budget-core, appear in the Makefile under several different config symbols. If more than one of these symbols is on, they will get added the to list of objects multiple times. The normal convention is to have a config symbol just the common object(s) and have the users of the that object either depend on or select that config symbol. This patch fixes all these issues. ttpci-eepom is under a new config symbol, and so is the budget-core module. The four different budget card types appear as sub-drivers under a main "SAA7146 DVB cards" option. Turning on budget-patch doesn't force AV7110. Drivers using SAA7146_VV have the necessary VIDEO_DEV dependency, so that it isn't possible to select SAA7146_VV without V4L being on.

This is necessary for capture apps like MPlayer that use different threads for capturing and channel tuning. Now the locking is only done for the ioctls that change properties of the device or access the i2c bus. It also removes some locks that look unnecessary: In em28xx_init_dev: the videodevice is not registered yet so nothing can access the hardware meanwhile, the device struct is not assigned to the interface yet so no race with disconnect is possible In em28xx_release_resources: it gets only called when dev->lock is already held Signed-off-by: Sascha Sommer Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/em28xx/em28xx-video.c | 151 ++++++++++++++++-------------- drivers/media/video/em28xx/em28xx.h | 2 +- 2 files changed, 80 insertions(+), 73 deletions(-) (limited to 'drivers') diff --git a/drivers/media/video/em28xx/em28xx-video.c b/drivers/media/video/em28xx/em28xx-video.c index 18b8568c634..bc495a11dc2 100644 --- a/drivers/media/video/em28xx/em28xx-video.c +++ b/drivers/media/video/em28xx/em28xx-video.c @@ -126,8 +126,6 @@ static struct v4l2_queryctrl em28xx_qctrl[] = { static struct usb_driver em28xx_usb_driver;

Scode is a table of 16 values (each with 12 bytes i2c sequence). Dcode is the entry of Scode table that should be used, given a certain frequency. The idea is that, depending on what frequency is selected, and according with a country-based (or standard-based?) table, the Xceive should be "hacked" to fine-tune that specific frequency. By default, Scode=0 is used, for undefined frequencies. Also, Scode=0 seems to be the most used value. This patch adds the capability of selecting a scode. However, extra work will be needed to allow auto-selecting the proper scode, for a given set of frequencies. I'm not sure what would be the proper way for implementing the dcode selection.

Instead of declaring local macros, create a tuner global macro for printing tuner errors. To preserve CodingStyle on all tuner_macros, a few CodingStyle violations were fixed at the other macros: - lines with more than 80 columns - two statements at the same line The patch also removes the CodingStyle violation of having emacs declarations inside de source code (CodingStyle chapter 18).

By masking the appropriate firmware bits off we can just use one "type" for the firmware searching and also flag when we are looking for a BASE, DTV or SCODE type firmware. This makes it much easier to track if we need to change device modes or flash an individual firmware part. Add a structure to remember what firmware properties we have. This contains the currently loaded/wanted base firmware (type), video std (id), video std requested (std_req), scode file and number in use. Incorporate said structure into the tuner private data. When checking whether the current firmware needs to be reloaded, first figure out exactly what "type" of firmware we want (base, std and scode), and then proceed to load the appropriate matching base, std-specific and scode records iff there are any changes required. This removes guesswork from the process because we no longer need to individually code a check for every tuning parameter's interactions.

The first (ZL10353 w/ firmware in ROM) is already supported; the latter two both require firmware and have either an MT352 or ZL10353 demodulator, and have a different IR receiver from the first. This introduces a new identify_state that can tell the difference between a "warm" device which is running the embedded firmware, and a "cold" device that needs us to upload firmware to it before it will work. We patch the uploaded device ID (like we do for other bluebird devices) to make it easy to identify the particular device variant when it reattaches. NB: These devices use a different firmware file from previous bluebird devices. You need a new firmware file to make this work.

MTS firmwares provide stereo decoding for 6 MHz BTSC/EIAJ and for monoaural audio decoding on 8 MHz firmwares. It seems that the option to use MTS or a standard-specific audio decoding depends on the way xc2028/3028 is connected. Instead of wasting 32 (or 64 bits) to signalize if the driver needs to use MTS firmware, this patch converts it to a bitfield that can be shared with other proprieties of xc2028/3028.

Cards with mute from external audio muxes are already fine on the other inputs and some recent tuners mute at least the radio on exit. But these mostly hybrid tuners are not fully backward compatible, since they must power down and mute regardless. For some included above, the MD7134 knows several, to switch on mute/automute to the TV input is functional and backward compatible for the applications, except that the tuners with tda9887 always mute on exit.

Actual start/stop of the pipeline is moved to the driver's kernel thread. Pipeline stages are controlled autonomously based on surrounding pipeline or application control state. Kernel thread management is also cleaned up and moved into the internal control structure of the driver, solving a set up / tear down race along the way. Better failure recovery is implemented with this new control strategy. Also with this change comes better control of the cx23416 encoder, building on additional information learned about the peculiarities of controlling this part (this information was the original trigger for this rework). With this change, overall encoder stability should be considerably improved. Yes, this is a large change for this driver, but due to the nature of the feature being worked on, the changes are fairly pervasive and would be difficult to break into smaller pieces with any semblence of step-wise stability.

However there are other hardware types potentially supportable, but the driver at the moment is not structured to make it easy to describe these minor variations. This changeset is the first set of changes to make such additional device support possible. Device attributes are held in several tables all contained within pvrusb2-devattr.c; all other device-specific driver behavior now derives from these tables.

However, the standard can be changed after the init phase. This effectively breaks the yuv output stream handler, since it relies on the different yuv planes being block aligned. This patch changes the setup, so that the block size is always the same. The decoder dma function has been modified to cope with the fact that the second yuv plane may no longer be block aligned. The start of the yuv frame must still be at the beginning of a block, so the stream write function has also been modified to ensure this is always true. Also, the stream write function will now initiate a yuv dma transfer as soon as a full frame is ready. It will not wait until the current write request has completed, or the stream buffer becomes full.

A few stray interlace related variables which were linked to individual frames have now been moved into the yuv_frame_info struct.

With this patch, yuv frames written to video48 are now handled by the existing IVTV_IOC_DMA_FRAME framework. As such, the frames are hardware buffered to avoid tearing, and honour scaling mode & field order options. Unlike the proprietary IVTV_IOC_DMA_FRAME ioctl, all parameters are controlled by the V4L2 API. Due to mpeg & yuv output restrictions being different, their V4L2 output controls have been separated. To control the yuv output, the V4L2 calls must be done via video48. If the ivtvfb module is loaded, there will be one side effect to this merge. The yuv output window will be constrained to the visible framebuffer area. In the event that a virtual framebuffer size is being used, the limit to the output size will be the virtual dimensions, but only the portion that falls within the currently visible area of the framebuffer will be shown. Like the IVTV_IOC_DMA_FRAME ioctl, the supplied frames must be padded to 720 pixels wide. However the height must only be padded up the nearest multiple of 32. This would mean an image of 102 lines must be padded to 128. As long as the true source image size is given, the padding will not be visible in the final output.

This makes easier to diff between the previous version and the newer one.

This where due to not properly preserving the minor inode after calling video_register. Since this driver is a reference for newer drivers, and it is possible to have more than one video device inside the machine, this patch makes vivi to dynamically allocate video_device struct. Thanks to Gregor Jasny for pointing the issue. Also, this patch removes a very anoying (but useless) message of not having a proper release call.

Especially mythtv users would find that the audio would often sound bad (aliased, or 'raspy'), mainly related to channel changes, many (all?) other users would find that there was no audio at all in the mpeg data from the encoder chip, unless the audio was manually unmuted. The patch includes the following modifications: Don't actually start the mpeg2 encoder until the device is read from by the application. Wait until the audio is stable for at least 400ms before starting the mpeg encoder. Mute/Unmute the audio when starting/stopping the mpeg encoder. Stop the mpeg encoder when changing parameters and when changing tuner frequency. Add a variable 'mpeg_active' to struct cx8802_dev to allow tracking of whether or not the mpeg2 encoder is active. Load the firmware on cx88-blackbird driver load.

I tested this from warm boots and cold boots (with long power down time to ensure the sram in the chip is emptied), and found that after the firmware upload the encoder is apparently not muted, making the unmutes unnecessary.

I've tested with other ATSC tuners just to confirm, using: us-ATSC-center-frequencies-8VSB Anyhow, as it turns out, the tuner-xc2028 *does* require a tuning offset for ATSC. Even though the linux-dvb api passes in center frequencies from userspace, apparantly the xceive firmware is already factoring in the tuning offset to center. In order to make the device function using the same scan files / channels.conf configurations as other atsc devices, we must offset by 1.75 MHz.

This will allow us to use dvb_attach in the future, along with removing the need to check the ops structure before having to check the pointer to the method being called.

However, on newer devices, this were replaced by a Vendor Class. This patch autodetects that an em28xx lacks Audio Class and auto-loads em28xx-alsa, for the devices that implements only a Vendor Class. For devices with Audio Class, snd-usb-audio module will provide an ALSA interface. This patch uses the request_module_async function as defined on cx88-mpeg.c, originally wrote by Markus Rechberger.

Otherwise, an OOPS is generated. On some cases, .mmap file handler used to took some time to be called. On those situations, mmap_mmapper() were called after iolock. This patch properly waits for mmap_mapper to be called, otherwise generating an error.

It should also work for the identical ADS/Tech FM Radio Receiver (formerly Instant FM Music) as soon as I find out the USB Vendor and Product ID. The driver is inspired by several other USB and radio drivers, but mainly from the D-Link DSB-R100 USB radio (dsbr100.c). The USB stick currently has an Si4701 FM RDS radio receiver. But the other Si470x devices are pin and register compatible, so that in the future the driver can easily be patched to support these too. Therefore I named the driver radio-si470x and the configuration option usb-si470x. The driver itself just provides the control function over the radio. For getting audio back, the device support the USB audio class, which is implemented in the already existing driver. I tested the driver in the last days, until it now satisfies all my functionality and robustness requirements. The application I used for testing was kradio.

Having two ways to say that a tuner is not present is not nice, since it may lead to bad setups. In fact, with the previous code, if a device were using has_tuner=0, but the user forces a tuner, with modprobe option tuner=type, the modprobe option won't work. Also, tveeprom returns TUNER_ABSENT, when tuner is unknown or absent. So, with the previous logic, in this case, the driver should set has_tuner=0, or has_tuner=1 otherwise. Instead of adding several additional tests and setups, better just to remove .has_tuner.
