      V4L/DVB (10190): cx88: Fix some Kbuild troubles · e32fadc4
      由 Mauro Carvalho Chehab 提交于 
      As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues:

drivers/built-in.o: In function `cx88_call_i2c_clients':
(.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend'
drivers/built-in.o: In function `cx8802_probe':
cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend'
cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends'

With those configs:

CONFIG_VIDEO_CX88=y
CONFIG_VIDEO_CX88_BLACKBIRD=y
CONFIG_VIDEO_CX88_DVB=m
CONFIG_DVB_CORE=m

After carefully examining the code, with the current code, several cx88 drivers
(cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module,
if one of them is marked as such. Just fixing Kconfig could create a very complex
set of rules. Also, this hides a problem with the current approach where the dvb
functionality weren't confined inside dvb module.

What happens is that:
	- cx88-i2c (part of cx8800) has some special rules if DVB;
	- cx88-mpeg (cx8802 module) has also part of DVB init code;
	- cx88-dvb has the rest of the dvb code;
	- cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not.

So, instead of doing some tricks at Kconfig and wait for a next breakage,
this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb.

Another problem is that cx8802 were being compiled, even without cx88-dvb
and cx88-blackbird modules.

While on this code, let's fix also a reported problem:

A solution for the issue were proposed here:

Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect
and solve the issues.

      V4L/DVB (6252): Adapt drivers to use the newer videobuf modules · c1accaa2
      由 Mauro Carvalho Chehab 提交于 
      PCI-dependent videobuf_foo methods were renamed as videobuf_pci_foo.

Also, videobuf_dmabuf is now part of videobuf-dma-sg private struct.
So, to access it, a subroutine call is needed.

This patch renames all occurences of those function calls to be
consistent with the video-buf split.

      V4L/DVB (6125): whitespace cleanup: replace leading spaces with tabs · b930e1d8
      由 Michael Krufky 提交于 
      There were many instances of 7-space indents spread throughout
the v4l-dvb tree.

This patch replaces the 7-space indents with tabs.  The whitespace cleaner
script doesn't catch these, because it assumes that all indents are 8-space.

      V4L/DVB (6083): cx88-alsa: Rework buffer handling · 05b27233
      由 Trent Piepho 提交于 
      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 (6023): cx88: Clean up some ugly and inconsistent printk()s · 5772f813
      由 Trent Piepho 提交于 
      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.

The changed printks in cx88-mpeg.c also needed lots of whitespace and
80-column fixes.

A bunch of misc changes in cx88-dvb.c and cx88-video.c to add message levels
or a consistent "cx88[?]/2" or "cx88[?]/0" prefix.

      V4L/DVB (6021): cx88: Copy board information into card state · 6a59d64c
      由 Trent Piepho 提交于 
      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.
