* V4L/DVB: videobuf: add queue argument to videobuf_waiton()Hans Verkuil2010-10-211-1/+1
| | | | | | | | | | | | | | | | videobuf_waiton() must unlock and relock ext_lock if it has to wait. For that to happen it needs the videobuf_queue pointer. Don't attempt to unlock/relock q->ext_lock unless it was locked in the first place. vb->state has to be protected by a spinlock to be safe.

| | | | | | | | | | | | Using an enum and removing the default case from switch statements accessing the value enables the compiler to emit a warning (enabled with -Wall) when an audio mode is not handled.

* V4L/DVB (6083): cx88-alsa: Rework buffer handlingTrent Piepho2007-10-091-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* V4L/DVB (6021): cx88: Copy board information into card stateTrent Piepho2007-10-091-25/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cx88 driver state stored the ID of the board type in core->board. Every time the driver need to get some information about the board configuration, it uses the board number as an index into board configuration array. This patch changes it so that the board number is in core->boardnr, and core->board is a copy of the board configuration information. This allows access to board information without the extra indirection. e.g. cx88_boards[core->board].mpeg becomes core->board.mpeg. This has a number of advantages: - The code is simpler to write. - It compiles to be smaller and faster, without needing the extra array lookup to get at the board information. - The cx88_boards array no longer needs to be exported to all cx88 modules. - The boards array can be made const - It should be possible to avoid keeping the (large) cx88_boards array around after the module is loaded. - If module parameters or eeprom info override some board configuration setting, it's not necessary to modify the boards array, which would affect all boards of the same type.

| | | | | | | | | | | | | | | | | | | | | | This patch changes the setting of the cx2388x notch filter to match that of the video capture sample frequency, removing some annoying interference lines THAT would appear when capturing composite video. This has been tested in PAL and NTSC TV norms. It sets the Y/C separation luma notch filter, which removes the chroma signal from the luma signal when using a composite input. The luma notch filter operates at the video decoder's frequency, not the ADC's frequency or at the frequency of the scaled video. Y/C separation happens after the sample rate converter, before video scaling. The datasheet provides plots of the filter response for three _video decoder_ frequencies, 4x Fsc, square pixel, and ccir601. These are the same three frequencies for the notch filter control. It seems pretty clear that this filter should be set based on the video decoder frequency. The cx88 driver always uses a video decoder frequency of 4xFsc.

* V4L/DVB (4002): Adjust VBI offset to match value reported in VBI formatTrent Piepho2006-06-251-3/+3
| | | | | | | | | | | The actual offset of the start of VBI data is incorrectly documented for both the cx2388x and bt8x8. For the cx2388x, it appears to be about 220 to 224 + VBI_V_DEL*2. The driver has been incorrectly reporting an offset of 244. This patch adjusts VBI_V_DEL to 10, so that the offset of 244 is correct. This is the same offset as the bttv driver, and expected by some software. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (4001): Cx88 NTSC VBI fixesMichael Schimek2006-06-251-1/+1
| | | | | | | | | VBI (Closed Caption, CC) capturing never worked in NTSC mode with the cx88 driver. They were tested with libzvbi and a patched version of tvtime. Signed-off-by: Michael H. Schimek <mschimek@gmx.at> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (3766): Correct buffer size calculations in cx88-core.cDuncan Sands2006-05-121-6/+10
| | | | | | | | | | | | The computation in cx88_risc_buffer suffers from the mistake: a non-zero padding value can cause more page borders to be crossed, leading to big buffer over-runs. This patch changes the additive constant from 3 + 4 to 4 It also changees the constant in cx88_risc_databuffer from 3 + 4 to 2, because 2 dwords are the correct vaule.

* V4L/DVB (3516): Make video_buf more genericMauro Carvalho Chehab2006-03-241-3/+3
| | | | | | | | | | | Video_buf were concerned to allow PCI devices to be used as video capture devices. This patch extends video_buf features by virtualizing pci-dependent functions and allowing other type of devices to use it. It is still DMA centric, although it may be used also by devices that emulates scatter/gather behavior or a DMA device Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
