Mike Isely [Tue, 22 Apr 2008 17:45:45 +0000 (14:45 -0300)]
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.

Wojciech Migda [Tue, 22 Apr 2008 17:45:36 +0000 (14:45 -0300)]
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.

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.
