This software opens both analog and dvb interfaces of saa7134. What happens is that some tuner commands are going to the wrong place, as shown at the logs: Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: using tuner params #0 (ntsc) Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808 Feb 12 20:37:48 opus kernel: tuner 1-0061: tv freq set to 67.25 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: using tuner params #0 (ntsc) Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: tv 0x07 0x10 0xce 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: tv 0x07 0x10 0xce 0x01 This happens due to a hack at TUV1236D analog setup, where it replaces tuner address, at 0x61 for 0x0a, in order to save a few memory bytes. The code assumes that nobody else would try to access the tuner during that setup, but the point is that there's no lock to protect such access. So, this opens the possibility of race conditions to happen. Instead of hacking tuner address, this patch uses a temporary var with the proper tuner value to be used during the setup. This should save the issue, although we should consider to write some analog/digital lock at saa7134 driver.

The affected functions cannot be called from an interrupt context, because they may process large buffers. In this case, interrupts are disabled for a long time. Functions, like dvb_dmx_swfilter_packets(), could be called only from a tasklet. This change set does hide some strong design bugs in dm1105.c and au0828-dvb.c. Please revert this change set and do fix the bugs in dm1105.c and au0828-dvb.c (and other files). On Sun, 15 Feb 2009, Oliver Endriss wrote: This changeset _must_ be reverted! It breaks all kernels since 2.6.27 for applications which use DVB and require a low interrupt latency. It is a very bad idea to call the demuxer to process data buffers with interrupts disabled!

Drivers should use a work-queue to feed the demuxer. Thank you for testing this changeset and discovering the issues on it.
