* V4L/DVB (8900): pvrusb2: Implement cropping pass throughMike Isely2008-10-121-1/+4
| | | | | | | | | | | | | This builds upon the previous pvrusb2 change to more formally implement full cropping support. This enables access from the driver's V4L interface, and enables access to full capabilities from sysfs as well. Note that this is only effective when in analog mode. It also will only work when the underlying digitizer's driver (saa7115 or cx25840 depending on the hardware) also implements the appropriate functions.

| | | | | | | | | | | 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.

| | | | | | | | | | | | | | Add basic framework for the DVB API. This is enough to control the tuner & demod of the digital frontend, but the stream & buffer handling is still missing. Additional note from Mike Isely <isely@pobox.com> - also, since these changes are still very experimental arrange for DVB changes to be compiled in via new CONFIG_VIDEO_PVRUSB2_DVB option, for now.

* V4L/DVB (7321): pvrusb2: Rework context handling and initializationMike Isely2008-04-241-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 (6692): pvrusb2: Centralize device specific attributes into a single ↵Mike Isely2008-01-251-4/+2
| | | | | | | | | | | | | | | | place The pvrusb2 driver currently supports two variants of the Hauppauge PVR USB2. However there are other hardware types potentially supportable, but the driver at the moment is not structured to make it easy to describe these minor variations. This changeset is the first set of changes to make such additional device support possible. Device attributes are held in several tables all contained within pvrusb2-devattr.c; all other device-specific driver behavior now derives from these tables.

* V4L/DVB (6691): pvrusb2: Rework pipeline state controlMike Isely2008-01-251-14/+50
| | | | | | | | | | | | | | | | | | | | | This is a new implementation for video pipeline control within the pvrusb2 driver. Actual start/stop of the pipeline is moved to the driver's kernel thread. Pipeline stages are controlled autonomously based on surrounding pipeline or application control state. Kernel thread management is also cleaned up and moved into the internal control structure of the driver, solving a set up / tear down race along the way. Better failure recovery is implemented with this new control strategy. Also with this change comes better control of the cx23416 encoder, building on additional information learned about the peculiarities of controlling this part (this information was the original trigger for this rework). With this change, overall encoder stability should be considerably improved. Yes, this is a large change for this driver, but due to the nature of the feature being worked on, the changes are fairly pervasive and would be difficult to break into smaller pieces with any semblence of step-wise stability.

| | | | | | | | | | | | | The pvrusb2 driver already has a method for extracting the FX2's program memory back out to a user application; this ability is used to facilitate manual firmware extraction as per the procedure documented on the pvrusb2 web site.

It also adds a file to show the radio minor as well. This can be useful for a program like pvr-radio.c (when it grows up), since this way it can search for the minor of the /dev/radioX device it opened and use the video minor of the same driver instance to get to the actual stream. The implementation looks kinda ugly. Feel free to improve (that is the reason behind separate patches anyway).
