* V4L/DVB (13223): pvrusb2: Soften encoder warning messageMike Isely2009-12-05
| | | | | | | | | | | | | | pvrusb2: Encoder failures are mostly recoverable by the driver. While it would sure be nice not to have the failure happen in the first place, this has been going on for years and I doubt that a real solution will ever present itself. I think that part's firmware is just slightly flakey and we have to deal with it. The driver does deal with it just fine, but the warning message going into the kernel log is probably a little more alarming than it should be. So try to soften up the warning somewhat.

| | | | | | | | | | | | | | onair devices Implement timed measurement of encoder operation for the first time it is run. This allows the driver to note when the encoder has been run successfully for at least 1/4 second. On top of that implement various bits to ensure that the encoder has been run once before digital streaming for OnAir devices. This is done via several core state machine tweaks.

* V4L/DVB (7313): pvrusb2: Make LED control into a device-specific attributeMike Isely2008-04-24
| | | | | | | | | | The pvrusb2 driver has used hardcoded logic to control the LED on the device. However this is really Hauppauge-specific behavior. This change defines a new device attribute for LED control and sets things up appropriately for Hauppauge devices.

* V4L/DVB (6700): pvrusb2: Soften the crashed encoder warning messageMike Isely2008-01-25
| | | | | | | | | | | | The pvrusb2 driver has been successfully recovering from a crashed encoder now for over 2 years. I think it's time to reduce the perceived severity of the warning message. While I'd still very much like to stop these crashes, the recovery logic is solid enough that the problem is effectively benign. No point in panicing the users over it.

* V4L/DVB (6692): pvrusb2: Centralize device specific attributes into a single ↵Mike Isely2008-01-25
| | | | | | | | | | | | | | | | 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 Isely2008-01-25
| | | | | | | | | | | | | | | | | | | | | 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.

* V4L/DVB (5034): Pvrusb2: Enable radio mode round #1Pantelis Koukousoulas2007-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is the logic that supports switching modes via e.g., echo radio > /sys/class/pvrusb2/sn-*/ctl_input/cur_val. To do the mode switching we need to: a) broadcast AUDC_SET_RADIO and b) issue the CX2341X_ENC_MUTE_VIDEO command to the encoder. The first is done by adding a new pvr2_i2c_op and having it trigger on input change, the second by adding this command in pvr2_encoder_start() and requesting an encoder restart on input change by setting stale_subsys_mask appropriately. The clues about AUDC_SET_RADIO and CX2341X_ENC_MUTE_VIDEO were kindly provided by Hans Verkuil on the pvrusb2 mailing list. The idea to implement mode switching this way (on input change) is due to Mike Isely. Why AUDC_SET_RADIO/VIDIOC_S_STD are used for switching? I can 't be sure, but I think this can be traced to a cornell student being the first to implement radio support in ivtv "as a different standard". I think the rest just evolved from there (it 's in the ivtv ML archives).

Implement V4L2 driver for the Hauppauge PVR USB2 TV tuner. The Hauppauge PVR USB2 is a USB connected TV tuner with an embedded cx23416 hardware MPEG2 encoder. There are two major variants of this device; this driver handles both. Any V4L2 application which understands MPEG2 video stream data should be able to work with this device.
