2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai
This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

2008-01-25V4L/DVB (6833): Don't limit cx88 audio routing to blackbird boardsRicardo Cerqueira
All cx2388 boards need the line-in audio to be routed from an external ADC (refered to as "ADC mode" in the spec sheet), since the chip is uncapable of dealing with baseband audio directly. So... this patch enables normal mode when using the tuner (TV or Radio), and enables ADC mode with any other source.

Fix lack of audio on the MPEG-2 stream of wm8775 based blackbirds. The wm8775 module initializes the audio input at "route 2", which doesn't hold true for all boards. The HVR-1300, for example, uses route 1 for tuner audio, and route 2 for baseband. So we must route the audio to the proper input depending on what video input is being used.

Remove the unnecessary BLACKBIRD_UNMUTE calls to the mpeg encoder in cx88-blackbird.c The encoder is never muted, hence unmuting should then only be necessary once after hardware initialization. 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.

2008-01-25V4L/DVB (6828): cx88-blackbird: audio improvementsJelle Foks
This patch should fix the 'muted audio' and 'raspy audio' problem for mpeg2 streams out of cx88-blackbird devices. 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.

2007-10-22V4L/DVB (6334): cx88: Change (struct cx8802_dev)->drvlist to a list_head and ↵Trent Piepho
fix bugs It was a struct cx8802_driver for no apparent reason. Nothing uses a cx8802_driver in the cx8802_dev struct. The only field that was used was devlist, a list_head. The code in cx8802_remove() that removed any loaded sub-drivers was broken. It would delete the current list entry, but didn't use list_for_each_safe. It also called list_del() on the list _head_ inside the list_for_each loop? It would crash if it was run, which I don't think can ever happen. Since the cx8802 sub-drivers use the cx8802 driver, they have to be unloaded first. So there isn't any way for a sub-driver to still be loaded when cx8802_remove() is called... Except maybe with PCI hot-plug, if one removes the PCI card while the drivers are loaded? So I left some code in to handle that if it's actually possible. It will remove the sub-drivers from the device cx8802_remove() was called on, and only that device. If one has two DVB cards and unplugs one, there is no reason to unload the DVB drivers for both cards. I have no way to test this, but it can't be worse than what was there before. cx8802_get_driver() is passed a cx8802_dev pointer and looks for the requested driver on that device. It first loops over the cx8802 device list looking for the device it was passed, which is pointless. It doesn't need to find the device pointer in the list, as it already has the pointer. The list_head in the cx8802_driver struct, which joins all the _drivers_ attached to a device, was named devlist. Changed that to drvlist, since the devlist is used for a list of _devices_ in other cx8802 structs.

Add two mute controls. One mutes everything, the other just mutes the analog pass-through output. Rename the existing volume control. The controls are now: Playback Volume Playback Switch Capture Switch These names might seem odd, but I believe they are more correct. The previous "Capture Volume" control didn't actually effect the volume of the captured audio. Instead it controls the volume of the analog pass-thought output. It appears that pass-through controls like this are usually considered to be in the playback direction, not capture. For example, "CAPTURE feedback Playback Volume" is the name used for a control that appears to have the same effect in the ca0106 driver. We only have one volume control, so we can omit the "CAPTURE feedback" part. If someone where to add PCM playback support to the driver, then this would be the volume control.

Use the balance control to make the mono volume control stereo. Note that full range isn't supported. The balance control attenuates one channel by 0 to -63 dB, and the volume control provides additional attenuation to both channels by another 0 to -63 dB. So the channel with the most attenuation has a range of 0 to -126 dB, while the other channel only has a range of 0 to -63 dB. ALSA volume controls don't appear to support this concept. I just limited the range to 0 to -63 total. Once you get to -63 dB, you're already at silence, so additional attenuation is pretty much pointless anyway.

2007-10-09V4L/DVB (6088): cx2341x: some controls can't be changed while the device is busyHans Verkuil
The driver should now pass the 'busy' state of the device to the cx2341x module whenever controls are set or tried. -EBUSY will be returned if the device is busy and the user attempts to modify certain 'dangerous' controls. It concerns controls that change the audio or video compression mode and bitrates. The cx88-blackbird and pvrusb2 drivers currently always pass '0' (not busy) to the cx2341x, effectively keeping the old behavior for now.

2007-10-09V4L/DVB (6085): cx88-alsa: Fix mmap supportTrent Piepho
The driver has long claimed to support mmap, but it didn't work at all. Some of the dma buffer parameters weren't set, and since video_buf uses vmalloc to allocate the buffer, a page callback is needed too.

2007-10-09V4L/DVB (6084): cx88-alsa: Eliminate snd_cx88_cardsTrent Piepho
The driver kepts a static global array of snd_card pointers for each card probed, which was never used. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-09V4L/DVB (6083): cx88-alsa: Rework buffer handlingTrent Piepho
Rework the way the DMA buffer is handled and IRQs are generated. ALSA uses a ring-buffer of multiple periods. Each period is supposed to corrispond to one IRQ. The existing driver was generating one interrupt per ring-buffer, as opposed to per period. This meant that as soon as the IRQ was generated, the hardware was already starting to re-write the beginning of the buffer. Since the DMA happens on a per-line basis, there was only a narrow window to copy the data out before the buffer was overwritten. The cx88 core RISC program generator is modified so that it can set the IRQ and counter flags to count every X lines of DMA transfer. This way we can generate an interrupt every period instead of every full ring-buffer. Right now only period of one line are supported, but it should be possible to support longer periods. Note that a WRITE instruction generates an IRQ when it starts, not when the transfer is finished. Thus to generate an IRQ when line X is done, one must set the IRQ flag on the instruction that starts line X+1, not the one that ends line X. Change the line size so that there are four lines in the SRAM FIFO. If there are not four lines, the analog output from the cx88's internal DACs is full of clicks and pops. Try to handle FIFO sync errors. Sometimes the chip generates many of these errors before audio data starts. Up to 50 sync errors will be ignored and the counter reset. Have the IRQ handler save the RISC counter to the chip struct, and then have the pointer callback use this to calculate the pointer position. We could read the counter from the pointer callback, but sometimes the sync errors on start up cause the counter to go crazy. ALSA sees this and thinks there has been an overrun. The IRQ hander can avoid saving the counter position on sync errors. The chip "opened" flag wasn't necessary. ALSA won't try to open the same substream multiple times. Probably this code was cut&pasted from the bt87x driver, which has multiple sub-streams for one chip. Do error checking for the videobuf mapping functions. snd_card_cx88_runtime_free() is useless and can be deleted.

2007-10-09V4L/DVB (6082): cx88: Improve risc instruction printing in sram channel dumpTrent Piepho
When the risc instrunctions from the CMDS were printed, instruction arguments weren't taken into account. This changes output like: cx88[0]: risc0: 0x1d010400 [ write sol eol irq1 cnt0 count=1024 ] cx88[0]: risc1: 0x0cac2800 [ INVALID sol eol 23 21 19 18 13 count=2048 ] cx88[0]: risc2: 0x1d010400 [ write sol eol irq1 cnt0 count=1024 ] cx88[0]: risc3: 0x0cac2c00 [ INVALID sol eol 23 21 19 18 13 count=3072 ] cx88[0]: risc0: 0x1d010400 [ write sol eol irq1 cnt0 count=1024 ] cx88[0]: risc1: 0x0cac2800 [ arg #1 ] cx88[0]: risc2: 0x1d010400 [ write sol eol irq1 cnt0 count=1024 ] cx88[0]: risc3: 0x0cac2c00 [ arg #1 ] Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-10-09V4L/DVB (6068): cx88-alsa: Use pci_dev->revisionTrent Piepho
The revision is part of the pci_dev struct, so there is no need to read it in. Stop storing the revision and latency in the chip struct, since they're never used after being printed out when the driver loads. linux/pci.h wasn't included. It was getting picked up something else, probably cx88.h, but this file uses struct pci_dev so it should include pci.h.
