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! On Mon, 16 Feb 2009, Trent Piepho wrote: I agree, this is bad. The demuxer is far too much work to be done with IRQs off. IMHO, even doing it under a spin-lock is excessive. It should be a mutex. Drivers should use a work-queue to feed the demuxer. Thank you for testing this changeset and discovering the issues on it.
