2007-10-09V4L/DVB (6116): ivtv: VBI cleanups and fixesHans Verkuil
Besides some VBI cleanups this patch also fixes a subtle problem with the VBI re-insertion stream where the PIO work handler wasn't called quickly enough, resulting in occasional corrupt data. Furthermore the CC output didn't disable CC correctly and at the right time, causing duplicates to be sent. An saa7127 fix for VPS output was also added: the wrong data was sent.

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 (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 (6066): cx88-alsa: Change order of interrupt enabling, fix spurious IRQsTrent Piepho
Currently the driver turns on audio interrupts, then sets the audio interrupt mask to select which interrupts to get. One could received unwanted interrupts since the mask is set _after_ interrupts have already been turned on. Change the order of the operations, and clear any audio interrupt status bits that are already set for good measure. Before changing the SRAM FIFO parameters, make sure the FIFO isn't being used. This shouldn't happen with just the ALSA driver, as it should never try to turn on FIFO/RISC/DMA while they are already on. However, the V4L driver needs to turn the audio FIFO on for analog audio output to work (undocumented cx88 bug). The FIFO parameters are in an inconsistent state while they are updated, and this results in many FIFO sync error IRQs if the FIFO is in use while it's in this inconsistent state. Also create and use a bunch of symbolic constants for audio interrupt mask bits. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
