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."

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.

The video_dev parameter, on tuner-xc2028 were used to pass i2c private data to

This parameter were used also as a magic number to idenfity if two drivers are

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

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.

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.

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.

The existing yuv code limits output to the display area occupied by the
framebuffer. This patch allows the yuv output to be 'detached' via
V4L2_FBUF_FLAG_OVERLAY.
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.

simple_set_tv() creates a buffer with 4 elements, and calls
simple_std_setup(), passing &buffer[1]. This makes the 5th element of buffer to
be initialized to 0, overriding some area outside the buffer.
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.
Thanks to Axel Rometsch <axel.rometsch@freenet.de> for pointing the issue.

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

This driver provides an interface between platform-specific camera
busses and camera devices. It should be used if the camera is connected
not over a "proper" bus like PCI or USB, but over a special bus, like,
for example, the Quick Capture interface on PXA270 SoCs. Later it should
also be used for i.MX31 SoCs from Freescale. It can handle multiple
cameras and / or multiple busses, which can be used, e.g., in
stereo-vision applications.

tuner-types is needed for tuner-simple, and does not need to be bound
to tuner-core. Any caller of tuner-simple, including tuner-core, needs
to pass a structure from tuner-types into tuner-simple at attach-time.

drivers can attach tuner-simple for hybrid dvb_frontend devices. We will
remove this dependency altogether as tuner refactoring phase 3 progresses.
