bdfbf95203 V4L/DVB (7598): em28xx: several fixes on gpio programming
em28xx-cards.c:
 - Fix reversed val/rst values in both analog_gpio and digital_gpio
   vectors
 - Fix crash that would was occurring during every analog startup
   while looping over gpio_ctl
 - Remove what appears to be a redundant setting of gpio_ctl->val
 - Don't use OREN538 demodulation for the HVR-950 (prevents ATSC
   scanning from working)

em28xx-dvb.c:
 - Tuner should be in digital mode when issuing the reset
 - Add copyright
 - Change struct definition (corresponds to fix in em28xx-cards.c for
   gpio_ctl looping)

The patch extends the default keymap of FlyVIdeo2000 IR remote control so that
this remote may also serve movie & music players in a better way.

I bought a SAA7130 TV tuner with a remote control having 3 additional button
as the default layout, exactly as:

1) labeled "<<<" : key code 0x19, may be used as "backward"in MPlayer,XMMS etc

2) labeled ">>>" : key code 0x1f, may be used as "forward"...

3) not labeled : key code 0x0a, may be used as "pause"...

Once have added these code definitions to the kernel, me got all these
operations available for viewing movies & listening music.

9faa2d7582 V4L/DVB (7580): Fix concurrent read from /proc/videocodecs
Observation one: ->write_proc and ->data assignments aren't needed. Removed.
Observation two: codecs lists are unprotected. Patch doesn't fix this.
Observation three:
	/proc/videocodecs printout is done to temporary _global_ buffer which
	is freed in between. Consequently, two users hitting this file can
	screwup each other.

Steps to reproduce:

	modprobe videocodec
	while true; do cat /proc/videocodecs &>/dev/null; done &
	while true; do cat /proc/videocodecs &>/dev/null; done &

The fix is switching to seq_files, this removes code, especially some
line-length "logic".

3b5fa928a6 V4L/DVB (7565): em28xx: fix buffer underrun handling
This patch fixes three related issues and a fourth trivial one:

- Use buffers even if no-one's currently waiting for them (fixes
  underrun issues);

- Don't return incomplete/mangled frames at the start of streaming and
  in the case of buffer underruns;

- Fix an issue which could cause the driver to write to a buffer that's
  been freed after videobuf_queue_cancel is called (exposed by the
  previous two fixes - for some reason, ignoring buffers that weren't
  being waited on worked around the issue);

- Fix a bug which could cause only one field to be filled in the first
  buffer (or first few buffers) after streaming is started.

aaea56afc3 V4L/DVB (7553): videobuf-vmalloc: fix STREAMOFF/STREAMON
There were a small bug on videobuf-vmalloc that were preventing STREAMOFF to
work. The issue is that vmalloc'ed mmaped memory should only be freed after
being sure that there aren't any mmap usage. Otherwise, the memory remap will
stop working, and the userspace won't receive any frames.

This bug were affecting some userspace applications, like tvtime.

videobuf-vmalloc.

There were some bugs on videobuf-vmalloc.

Basically, remap were called with a wrong parameter. Due to that, a later remap

videobuf-core.

This patch fixes the remap and removes the hacks.

TODO:

- V4L2_MEMORY_USERPTR is not implemented yet. This method should be
  properly implemented, in order to work with a few userspace applications.

- The driver also doesn't implement V4L2_MEMORY_OVERLAY. This method is used
  only by a few applications, and are becaming obsolete, due to the increment
  of cpu performance. So, most apps prefer to retrieve data to an internal
  buffer, doing some processing like de-interlacing.

e0fadfd34d V4L/DVB (7548): Various fixes for the em28xx videobuf code
- Aborting buffer_filled if no-one's waiting on the waitqueue probably isn't
  what we want, since just because no-one's waiting for it now doesn't mean they
  wouldn't dequeue it in time. (vivi gets away with this, possibly because it
  can fill each buffer much faster.)

- The first BUG_ON(lencopy <= 0); really isn't worth causing a kernel panic
  over, especially since there are some reasons why it could trigger in normal use.

- The top and botom frames are actually the wrong way around.

Also, it reduced its size by about 5.42% on i386 arch (and about 7.5% on x86_64):

  39113    4876      40   44029    abfd old/em28xx.ko
  36731    4868      40   41639    a2a7 /home/v4l/master/v4l/em28xx.ko

Also, the preliminary tests, made on a single core 1.5 MHz Centrino showed
that CPU usage reduced from 42%-75% to 28%-33% (reports from "top") command.

A test with time command presented an even better result:

This is the performance tests I did, running code_example to get 1,000 frames
@29.995 Hz (about 35 seconds of stream), tested on a i386 machine, running at
1,5GHz:

	The old driver:

$ time -f "%E: %Us User time, %Ss Kernel time, %P CPU used" ./capture_example
0:34.21: 8.22s User time, 25.16s Kernel time, 97% CPU used

	The videobuf-based driver:

$ time -f "%E: %Us User time, %Ss Kernel time, %P CPU used" ./capture_example
0:35.36: 0.01s User time, 0.05s Kernel time, 0% CPU used

	Conclusion:

The time consumption to receive the stream where reduced from about 33.38
seconds to 0.05 seconds.

78e92006f4 V4L/DVB (7538): Adds selectable adapter numbers as per module option
The adapter_nr module options can be used to allocate static adapter
numbers on a driver level. It avoids problems with changing DVB apapter
numbers after warm/cold boot or device unplugging and repluging.

Each driver holds DVB_MAX_ADAPTER long array of the preferred order of
adapter numbers.

options dvb-usb-dib0700 adapter_nr=7,6,5,4,3,2,1,0 would result in a
reversed allocation of adapter numbers.

With adapter_nr=2,5 it tries first to get adapter number 2 and 5. If
both are already in use it will allocate the lowest free adapter number.

137d1cb19d V4L/DVB (7493): videobuf: Avoid deadlock with QBUF and bring up to spec for empty queue
Add a waitqueue to wait on when there are no buffers in the buffer queue.
DQBUF waits on this queue without holding vb_lock to allow a QBUF to happen.
Once a buffer has been queued we recheck that the queue is still streaming and
wait on the new buffer's waitqueue while holding the vb_lock.  The driver
should come along in a timely manner and put the buffer into its next state
finishing the DQBUF.

By implementing this waitqueue it also brings the videobuf DQBUF up to spec and
it now blocks on O_NONBLOCK even when no buffers have been queued via QBUF:

"By default VIDIOC_DQBUF blocks when no buffer is in the outgoing queue."
 - V4L2 spec

58e6f95e61 V4L/DVB (7474): support key repeat with dib0700 ir receiver
This patch enables support for repeating last event when a key is holded
down with dib0700 devices. It works with rc5 and nec remotes.
It also fixes an annoying bug that floods kernel log with "Unknown key"
messages after each keypress. This happened because the driver was not
resetting infrared register after each poll so it kept polling last key
even if nothing was being pressed. Fixing this, (calling rc_setup after
each poll), permits to implement key repeat.

This board has a s5h1409 demod, plus a xc30x8 tuner (probably, xc3018).

This patch adds proper support for radio, video, s-video, composite and ATSC.
However, support for radio and video depends on having s5h1409 i2c gate open,
otherwise, xc30x8 chip won't be visible.

For a better support, some rework is needed on cx88 driver, to allow adding
xc30x8 to i2c bus without sending i2c 0 byte reading to 0xc2 address.

Thanks to Vanessa Ezekowitz <vanessaezekowitz@gmail.com> for helping to figure

03dea86de2 V4L/DVB (7401): radio-si470x: unplugging fixed
This patch fixes several kernel oops, when unplugging device while it is in
use:

Basically the patch delays freeing of the internal variables in
si470x_usb_driver_disconnect, until the the last user closed the device in
si470x_fops_release. This was implemented a while ago with the help of Oliver
Neukum.

I tested the patch five times (unplugging while in use) without oops coming
from the radio-si470x driver anymore. A remaining oops was coming from the
usbaudio driver, but this is someone else task. Hopefully this fixed all
unplugging issues.

b412ba781a V4L/DVB (7399): Removes video_dev from tuner-xc2028 config struct
The video_dev parameter, on tuner-xc2028 were used to pass i2c private data to
tuner_callback. Since the driver already have a pointer to i2c_adap->algo_data,
uses this instead.

This parameter were used also as a magic number to idenfity if two drivers are
trying to register the same xc3028 tuner. This occurs with boards with DVB
support, where both DVB and V4L drivers will share the same tuner.

Instead of using the algo_data as a private number, after this patch, the
driver will use i2c_adap->dev, with seems more consistent.

There are some restrictions:
- The 2nd DVB-S section will only work if the 1st is configured for DVB-S too.
  so "options saa7134-dvb use_frontend=0,1" won't work.
- Currently it is not possible to set the higher LNB supply voltages, so
  14V instead of 13V in the 2nd section.
- It is not possibe to turn off the 2nd LNB supply independently.
This comes from the problem that the 2nd section can't access the i2c interface
of the LNB supply chip.

It was being detected as a GENERIC UNKNOWN CARD both by the 2.6.18
kernel and the latest v4l-dvb drivers, but it did not work at all. The
card has sixteen (16) BNC video inputs, four of them on the board itself
and twelve on three daughter-cards. It has a single bt878 chip, no tuner
and what looks like and audio input. After doing some research I managed
to get only eight channels working by forcing card=125 and those DID NOT
match channels 0-7 on the card, and no audio.

Based on what was working for card=125, I added the card definition
block, added a specific muxsel routine and got the card working fully
with xawtv, where the sixteen channels show up as Composite0 to
Composite15, matching the channel labels in the card and daughter-cards.
I have made no efforts yet to get audio working, but would appreciate
any pointers.

4a24ce3a17 V4L/DVB (7329): add flag to allow software demux to recognize the output type
Previously, the macro DVR_FEED, which is used to recognize and filter
out duplicate packets going to the DVR device, used the TS_PAYLOAD_ONLY
flag to identify a packet's destination.

This kind of filtering was introduced by the following two changesets:

Now, that it is possible to record TS PIDs using the demux device by
setting the output type to DMX_OUT_TSDEMUX_TAP, checking TS_PAYLOAD_ONLY
is not sufficient anymore. Therefore another flag, TS_DEMUX, is added to
specify the output type of a feed.

This allows multiple clients to filter the same TS PID on a demux device
simultaneously.

794b16072e V4L/DVB (7321): pvrusb2: Rework context handling and initialization
This change significantly rearranges pvr2_context level initialization
and operation:

1. A new kernel thread is set up for management of the context.

2. Destruction of the pvr2_context instance is moved into the kernel
   thread.  No other context is able to remove the instance; doing
   this simplifies lock handling.

3. The callback into pvrusb2-main, which is used to trigger
   initialization of each interface, is now issued from this kernel
   thread.  Previously it had been indirectly issued out of the work
   queue thread in pvr2_hdw, which led to deadlock issues if the
   interface needed to change a control setting (which in turn
   requires dispatch of another work queue entry).

4. Callbacks into the interfaces (via the pvr2_channel structure) are
   now issued strictly from this thread.  The net result of this is
   that such callback functions can now also safely operate driver
   controls without deadlocking the work queue.  (At the moment this
   is not actually a problem, but I'm anticipating issues with this in
   the future).

5. There is no longer any need for anyone to enter / exit the
   pvr2_context structure.  Implementation of the kernel thread here
   allows this all to be internal now, simplifying other logic.

6. A very very longstanding issue involving a mutex deadlock between
   the pvrusb2 driver and v4l should now be solved.  The deadlock
   involved the pvr2_context mutex and a globals-protecting mutex in
   v4l.  During initialization the driver would take the pvr2_context
   mutex first then the v4l2 interface would register with v4l and
   implicitly take the v4l mutex.  Later when v4l would call back into
   the driver, the two mutexes could possibly be taken in the opposite
   order, a situation that can lead to deadlock.  In practice this
   really wasn't an issue unless a v4l app tried to start VERY early
   after the driver appeared.  However it still needed to be solved,
   and with the use of the kernel thread relieving need for
   pvr2_context mutex, the problem should be finally solved.

29bf5b1d75 V4L/DVB (7297): pvrusb2: Dynamically control range of input selections
This follows from defining the available inputs as device attributes.
This change causes the driver to adjust its list of inputs based on
those attributes.  Now, for example, the FM radio will appear as a
choice only if the hardware supports an FM radio.

1aaac60fec V4L/DVB (7296): pvrusb2: Define device attributes for all input modes
Different devices support different input types.  Up until now we've
really been assuming that everyone has an analog tuner, an FM radio,
composite, and s-video inputs.  But as we add other devices, these
assumptions are no longer true.  The way to deal with this is to
define the available inputs as additional device attributes, so that
the driver can adjust its internal behavior accordingly.

27dea3eb66 V4L/DVB (7294): : tuner and radio addresses are missing for the PixelView PlayTV card
The PixelView PlayTV card definition structure was missing initialization of
the tuner_addr and radio_addr fields. As a result it was impossible to have the
tuner initialized using parameters specified while loading the bttv.ko module.

This regression became visible after the v4l rearrangements introduced
somewhere around 2.6.15 kernel version.

The root cause for the tuner initialization failure is located in the
attach_inform function in the bttv-i2c.c file.

There at the very beginning the addr variable holding the tuner device address
is initialized with the value taken from the bttv_tvcards array.

For the PixelView PlayTV card the tuner address field (and the radio address as
well) was uninitialized, and thus equal 0. Later in that function execution of
the TUNER_SET_TYPE_ADDR tuner command is guarded with check for the tuner
address either equal ADDR_UNSET, or client->addr.

Since both are non-zero (the latter in case of the card owned by me at the
runtime is equal 0x61) the TUNER_SET_TYPE_ADDR command is not executed, and
consequently in the tuner_attach function in the tuner-core.c file call to
i2c_attach_client does not result in assigning the tuner type variable with the
requested value.

Providing initialization of the tuner_addr and radio_addr with ADDR_UNSET
values as it is already done for other tv cards defined in bttv-cards.c ensures
that the tuner initialization is done correctly, just as it used to be in the
2.6.14 kernel.

b01cd93789 V4L/DVB (7293): DMX_OUT_TSDEMUX_TAP: record two streams from same mux, resend
Currently (in linux-2.6.24, but linux-dvb hg looks similar), the
dmx_output_t in the dmx_pes_filter_params decides two things: whether
output is sent to demux0 or dvr0 (in dmxdev.c:dvb_dmxdev_ts_callback),
*and* whether to depacketise TS (in dmxdev.c:dvb_dmxdev_filter_start).
As it stands, those two things can't be set independently: output
destined for demux0 is depacketised, output for dvr0 isn't.

This is what you want for capturing multiple audio streams from the same
multiplex simultaneously: open demux0 several times and send
depacketised output there. And capturing a single video stream is fine
not what you want: you want multi-open (so demux0, not dvr0), but you
want the TS nature preserved (because that's what you want on output, as
you're going to re-multiplex it with the audio).

At least one existing solution -- GStreamer -- sends all its streams
simultaneously via dvr0 and demuxes again in userland, but it seems a
bit of a shame to pick out all the PIDs in kernel, stick them back
together in kernel, and send them to userland only to get unpicked
again, when the alternative is such a small API addition.

The attached patch adds a new value for dmx_output_t:
DMX_OUT_TSDEMUX_TAP, which sends TS to the demux0 device. With this
patch and a dvb-usb-dib0700 (and UK Freeview from Sandy Heath), I can
successfully capture an audio/video PID pair into a TS file that mplayer
can play back.

This is based on a original patch thanks to Markus Rechberger that added xc3028

This patch moves saa7134_tuner_callback to saa7134-cards, originally used only
by tda8290 DVB-S boards. The callback was made more generic to support other
tuners.

By default, the yuv output window will be restricted to the framebuffer
dimensions and the output position is relative to the top left corner of the
framebuffer. This matches the behaviour of previous versions.

If V4L2_FBUF_FLAG_OVERLAY is cleared, the yuv output will no longer be linked
to the framebuffer. The maximum dimensions are either 720x576 or 720x480
depending on the current broadcast standard, with the output position
relative to the top left corner of the display. The framebuffer itself can be
resized, moved and panned without affecting the yuv output.

Also, simple_std_setup() receives a buffer as parameter, but the buffer is
just overriden after the call, so, it doesn't make much sense to pass it as a
parameter.

This patch removes buffer[] from the function call, creating, instead, a local
var to be used internally.

1b1cee35de V4L/DVB (7227): saa7134: fixed DVB-S support for Medion/Creatix CTX948
The I2C bus interface of the LNB supply sits behind the i2c gate of the
tda10086, so wrappers were necessary for the set_voltage functions.

For the time being, the board will show up as MD8800

Many thanks to Hermann Pitton for his help

Both camera drivers can function without GPIO support, in which case they

gpio_is_valid tests - they are repeated in bus_switch_request() functions.

f000fd8093 [ALSA] Fix synchronize_irq() bugs, redundancies
free_irq() calls synchronize_irq() for you, so there is no need for
drivers to manually do the same thing (again).  Thus, calls where
sync-irq immediately precedes free-irq can be simplified.

However, during this audit several bugs were noticed, where free-irq is
preceded by a "irq >= 0" check... but the sync-irq call is not covered
by the same check.

So, where sync-irq could not be eliminated completely, the missing check
was added.

044dfc99fe V4L/DVB (7486): radio-cadet: wrap PNP probe code in #ifdef CONFIG_PNP
Wrap PNP probe code in #ifdef CONFIG_PNP.

Without this change, we'll have unresolved references to pnp_get_resource()
function when CONFIG_PNP=n.  (This is a new interface that's not in mainline
yet.)

31c8cc9742 V4L/DVB (7464): Convert driver to use a single SRAM memory map
This reduces the memory footprint and removes the need to
manually configure each map, which lead to a bug where
the Fusion EXP 5 board broke for a while.
This also fixes digital support again for
the DViCO FusionHDTV5Express.
