[RFCv2 PATCH 00/15] saa7134: cleanup

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is the second version of an earlier cleanup patch series:

http://www.mail-archive.com/linux-media@xxxxxxxxxxxxxxx/msg62863.html

Several patches of that earlier series have already been merged, but the move
of the queue data away from saa7134_fh caused some concern.

After testing with xdtv and xawtv I can say that recording while displaying
at the same time works OK. Neither of these apps is combining streaming and
reading as Mauro suspected. Mauro, I wonder if you were confused with overlay
plus streaming?

Note that xdtv calls STREAMON before calling QBUF, something saa7134 doesn't
like at all (not related to any of my changes). I had to modify xdtv to queue
before calling STREAMON before it would even work with saa7134.

Anyway, I've kept my changes from the earlier patch series and added a few
other issues I found (particularly with saa6588).

I also tried to replace .ioctl by .unlocked_ioctl, but I got into a messy
videobuf situation, so I've postponed that.

Regards,

	Hans
