V4L/DVB (6116): ivtv: VBI cleanups and fixes

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.

Trent Piepho [Fri, 24 Aug 2007 04:06:34 +0000]
V4L/DVB (6083): cx88-alsa: Rework buffer handling

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 (6066): cx88-alsa: Change order of interrupt enabling, fix spurious IRQs

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.

V4L/DVB (6047): ivtv: Fix scatter/gather DMA timeouts

It turns out that the cx23415/6 DMA engine cannot do scatter/gather DMA
reliably. Every so often depending on the phase of the moon and your
hardware configuration the cx2341x DMA engine simply chokes on it and
you have to reboot to get it working again.

This change replaced the scatter/gather DMA by single transfers at a time,
where the driver is now responsible for DMA-ing each buffer.

UDMA is still done using scatter/gather DMA, that will be fixed soon.

Many thanks to Mark Bryars <mark.bryars@etvinteractive.com> for discovering
the link between scatter/gather and the DMA timeouts.

V4L/DVB (6023): cx88: Clean up some ugly and inconsistent printk()s

Get rid of the "CORE" prefix from cx88 printks.  It was only used a few times,
and it makes it look like they're coming from the kernel core or something.

Fix the message, "TV tuner 60 at 0x1fe, Radio tuner -1 at 0x1fe", by adding a
"cx88[0]" prefix to be consistent, and to keep people who grep their dmesg
output for cx88 from missing it.  Get rid of the addresses, which are always
wrong.  The addresses are always set to -1, but because it's an unsigned 8-bit
value, the left shift converts it to the nonsense address 0x1fe.

In the cx8802 driver, some cut and pasted code prefixed lines with "CORE
cx88[0]:", which has been changed to "cx88[0]/2:" like the other printks from
the cx8802 driver.

Also fix some ugly printks in the cx8802 driver that used __FUNCTION__ for
KERN_INFO and KERN_ERR messages.

V4L/DVB (6022): cx88: Move card core creation from cx88-core.c to cx88-cards.c

A lot of code in cx88-cards.c was only used by cx88-core.c when the core state
is first allocated and initialized.  Moving that task to cx88-cards makes the
driver simpler and the files more self contained.

- Module parameters tuner, radio, card, and latency move to cx88-cards.c
- cx88_boards is made static
- cx88_subids is made static and const
- cx88_bcount is eliminated
- cx88_idcount is eliminated
- cx88_card_list() is made static
- cx88_card_setup_pre_i2c() is made static
- cx88_card_setup() is made static
- cx88_pci_quirks() is moved from cx88-core to cx88-cards
  The function argument "char *name" is made const too
- get_ressources() is moved from cx88-core to cx88-cards, and renamed to
  cx88_get_resources()
- The code to allocate and initialize the core state struct and the chip is
  moved out of cx88-core.c:cx88_get_core() and into a new function in
  cx88-cards.c, cx88_core_create().  This makes both functions simpler.

Trent Piepho [Wed, 15 Aug 2007 17:41:57 +0000]
V4L/DVB (6021): cx88: Copy board information into card state

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.

V4L/DVB (5997): cx25840: fix audio mute handling and reporting

Audio muting for the tuner input was implemented by stopping the
audio microcontroller and restarting it on unmute. However, it
appears that this method can actually crash the audio firmware.
It's rare and seems to happen with NTSC only.

It has been reimplemented by setting to volume to 0. In addition, the
reporting of the mute state has been improved as well: it used to be
impossible to detect whether the audio was muted by the user or if it
was muted due to the microcontroller trying to detect the audio
standard. This is now clearly stated.

Trent Piepho [Fri, 3 Aug 2007 21:32:38 +0000]
V4L/DVB (5978): tuner: Better tuner radio support

Add radio support for the Thomson DTT7612 tuner.

This tuner uses a different 1st intermediate frequency than the other radio
tuners supported (a lot of NTSC radio tuners probably need this change too).

Add a new tuner-simple parameter, radio_if.  It selects the 1st IF used for
radio reception.  The radio frequency setting code in tuner-simple now uses
this field, instead of a special case select() block for each tuner with radio
support.

The tuner parameters for tuners that used a 33.3 MHz RIF now set radio_if to 1
in tuner-types.c.

The Thomson DTT7612 gets radio_if = 2, also add has_tda9887 = 1 and
fm_gain_normal = 1.

Add some defines for tda9887 bits that control IF setting in radio mode.

Add a new tda9887 config option, TDA9887_RIF_41_3, that selects a 41.3 MHz
radio IF.

Fix the way tda9887 radio options work.  The driver was modifying the default
radio mode config templates based on the TDA9887_XXXX flags.  This means that
_all_ tuners would get the same settings.  If you had a one tuner than used
TDA9887_GAIN_NORMAL and one that didn't, both would get the setting.  Now the
tda9987 driver just checks if tuner mode is radio and then applies the config
settings directly to the data being sent, just like how all the TV mode
settings already work.

The PLL setting math is made a little more accurate.

And a grammar error in a printk is fixed.
