This patch series converts the cx88 driver to vb2. Tested with NTSC and
PAL, video, vbi, audio, mpeg and dvb-t on a Hauppauge WinTV-HVR3000 and
a Hauppauge WinTV-HVR1300.
I see this as something for 3.19 so that there is enough time for testing
since this is a popular card.
Regards,
Hans

What happens here is that sometimes the DMA engine stops on cx88 and it needs to be restarted under some temporary errors. I don't remember the exact condition, as I don't touch on cx88 on several years, but I think it happens when the signal drops (for example, if the antenna cable gets removed, but not 100% sure). So, removing this code will cause regressions.

No, it won't. Read carefully how the 'queued' list is used: the only time that an element is added to that list is in buffer_queue() if the width, height or format has changed while streaming. But that can never happen (at least, not after REQBUFS) and that case was removed in patch 01/16. So after patch 01/16 nobody is ever adding buffers to the queued list anymore and it can be removed. This patch has nothing to do with restarting DMA. Patch 04/16 is the one that removes the restarting of DMA. I did a fair amount of regression and duration testing to see if I could reproduce a stopped DMA without being able to. I'm fairly certain that included switching frequency between valid/invalid channels, but I can retry that just to be sure. I am very skeptical that this really has to do with DMA issues: it looks much more like a poorly written driver. As my commit log to patch 04 says the cx88 driver allows userspace to drain all buffers and at that moment it has to halt the DMA and restart when a new buffer is queued up. But it is much simpler and more robust to just keep streaming by always keeping one buffer around, just as almost all other non-usb drivers do. I have not been able to find any reports that actually mention that the DMA can stop. The same change was done to cx23885 and no reports of any DMA problems have been reported for that either, and I expect that both devices use very similar DMA IP.

That happens if the signal is not too stable (e. g., either the chrominance or luminance or audio carrier is not properly detected). You would likely need a life weak signal and/or too much interference to be able to get it. I'm pretty sure I got those "cx8802_restart_queue: " from time to time without changing any parameters, during "normal" reception of some weak channels where I used to live (basically, using internal antennas). > I am very skeptical that this really has to do with DMA issues: it looks much more > like a poorly written driver.

I may try to test it with an internal antenna, but this can take some time, as I'm currently trying to get rid of the patch backlog, and I have other priorities to work after handling the backlog.

And since this affects blackbird, alsa, core, dvb, vbi and video the changes are all over. What made this more difficult was the peculiar way the risc program was setup. The driver allowed for running out of buffers in which case the DMA would stop and restart when the next buffer was queued. There was also a complicated timeout system for when buffers weren't filled. This was replaced by a much simpler scheme where there is always one buffer around and the DMA will just cycle that buffer until a new buffer is queued. In that case the previous buffer will be chained to the new buffer. An interrupt is generated at the start of the new buffer telling the driver that the previous buffer can be passed on to userspace. Much simpler and more robust.

Especially complicated command like CX2341X_ENC_STOP_CAPTURE takes much more time than 10 ms. Increase the timeout to 1 second, just as ivtv does (the cx88-blackbird has the same IP core for MPEG compression as ivtv). This solves a nasty issue where STOP_CAPTURE would timeout and the mailbox is left in a busy state, making it impossible to start streaming a second time without reloading the driver first.
