* V4L/DVB (7703): pvrusb2: Fix minor problem involving ARRAY_SIZE confusionMike Isely2008-04-24

* V4L/DVB (7702): pvrusb2: Rework USB streaming start/stop executionMike Isely2008-04-24
| | | | | | | | | | | | | The commands to start / stop USB streaming for an analog device are fairly standard, owing to the fact that all supported devices apparently started from the same common reference design. However with digital mode, the commands seem to vary by vendor. This change makes that variance more explicit. It also cleans up a related problem for OnAir devices which prevented digital mode from working at all.

* V4L/DVB (7701): pvrusb2: Centralize handling of simple FX2 commandsMike Isely2008-04-24
| | | | | | | | | | | | | Numerous places in the driver need to issue simple commands to the FX2 microcontroller (e.g. only 1 or 2 bytes, no reply needed). Previously each place that did this, had to take lock, set up a central buffer, and call the function to perform the handshake. This change puts these steps into a single spot. This also has the effect of removing the need to mess with the control lock from numerous places in the code.

| | | | | | | | | | | Move pvr2_dvb_adapter usage out of the pvrusb2 driver core - it's really private to the pvrusb2-dvb module and nothing outside of the dvb implementation should care about it. Creation / destruction of the pvr2_dvb_adapter instance is now contained entirely within pvrusb2-dvb.c.

| | | | | | | | | | | In the end we'd like the dvb interface to always be present - even for analog devices (via the mpeg encoder). However right now pvrusb2-dvb won't operate correctly if the hardware doesn't have a digital tuner, so don't initialize the DVB interface unless we know we have a digital tuner.

* V4L/DVB (7689): pvrusb2-dvb: Rework module tear-downMike Isely2008-04-24
| | | | | | | | | | | Rather than making an explicit call to tear down the pvrusb2-dvb module, use the callback in the pvr2_channel structure. This has the advantage that now tear-down only happens when it makes sense. The previous implementation had scenarios where it was possible for the tear-down call to happen without a prior initialization.

* V4L/DVB (7688): pvrusb2: Clean up dvb streaming start/stopMike Isely2008-04-24
| | | | | | | | | | | | Eliminate the need for a separate pvr2_dvb_fh; since in the DVB context there can only ever be a single instance then there is no need for a separate instance to handle streaming state. This simplifies the module. Also move streaming start/stop out of the feed thread and into the driver's main context - which makes it possible for streaming start up failures to be detected by the DVB core.

| | | | | | | | | | The pvrusb2-dvb feed thread cannot be allowed to exit by itself without first waiting for kthread_should_stop() to return true.

| | | | | | | | | | | | | | Creator The pvrusb2 driver normally picks up the default video standard from the eeprom on Hauppauge devices, but the OnAir HDTV and OnAir Creator are not Hauppauge devices, and do not store this information in any eeprom.

* V4L/DVB (7321): pvrusb2: Rework context handling and initializationMike Isely2008-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* V4L/DVB (7320): pvrusb2: Eliminate timer race during tear-downMike Isely2008-04-24
| | | | | | | | | | | The pvrusb2 tear-down logic was clearing two timers before stopping its internal work queue. That left a tiny window open where the work queue might run after the timers are stopped, possibly starting them again. This could lead to dangling pointers and an oops.

| | | | | | | | | | | | | The pvrusb2 driver dynamically generates an enumeration of support video standard combinations based on which video standard bits are set. ATSC modes don't fall into this since they are by nature not analog. The pvrusb2 driver has been warning about an inability to classify ATSC standards. This change causes the classification algorithm to ignore any ATSC standards (such things are better handled elsewhere anyway).
