Hi all,
I'm looking to implement a hardware pid filter for a card I'm working
on. I've been looking at how other drivers do this however all the
drivers I've looked at still seem to call the software filter routines
to pass data to user space. For example I've been looking at the flexcop
(ie b2c2) driver and whilst that has a hardware filter, the interrupt
service routine seems to always call flexcop_pass_dmx_data or
flexcop_pass_dmx_packets from dvb/b2c2/flexcop.c which both call
dvb_dmx_swfilter_packets or dvb_dmx_swfilter respectively.
I had assumed that I would be able to make a ts stream coming from a
hardware demux directly available to demux clients and dvr0, but no
other budget driver (ie without mpeg/video out) seems to do this without
using the swfilter. Can anyone point me at a driver which does similar
to what I'm trying to implement or am I just missing something.
Thanks in advance,
Phil
