g'day,
i recently upgraded my mythtv backend machine to much faster hardware (dual
core goodness).
my system consists of 3 DVB-T single-tuner cards & 1 analog tuner.
specifically:
1 x DvICO Fusion HDTV DVB-T1 (OEM version of T Plus;
requires: cx88, cx2388x, cx88-dvb, Zarlink MT352 frontend
1 x Twinham VisionPlus (bt878
requires: bt878, dvb-bt8xx, DST frontend
1 x AverMedia AV-771
requires: bt878, dvb-bt8xx, Zarlink MT352 frontend
1 x Hauppage WinTV (analog; bt848-based, requires bttv)
due to the newness of the motherboard, i need to run a 'recent' (2.6.18rc5)
kernel. previously i used to run a 2.6.13 kernels without with whatever the
stock dvb/v4l sync was as of 2.6.13. (no need for tip-of-tree dvb).
however, as of 2.6.18-rc5 kernel, dvb no longer functions correctly, so i
need to run with tip-of-tree dvb.
i've found that with tip of tree, while i can get everything to "work", i
need to do some messing with modprobes in my rc.local file. specifically,
while udevstart/hotplug/udev identify the DVB cards correctly, they don't
load the mt352 module.
as such, what happens is that i get this in startup messages indicating
cx88-dvb couldn't attach to the mt352 frontend as the mt352 module hadn't
loaded, thus the DvICO Fusion HDTV DVB-T1 is inoperable:
DVB: Unable to find symbol mt352_attach()
cx88[0]: frontend initialization failed
likewise, the DST frontend isn't automatically loaded/identified, so the
Twinham VisionPlus card isn't operable either. and dvb-bt8xx isn't
automatically loaded, so the AverMedia AV-771 is also inoperable.
by adding the following into my /etc/rc.d/rc.local script, i get all cards
working:
modprobe mt352
rmmod cx88-dvb
modprobe cx88-dvb
modprobe dst
modprobe dvb-bt8xx
(i need to rmmod cx88-dvb since it was already loaded but mt352 wasn't)
system was originally Fedora Core 3, much of it since updated to FC4 & FC5..
should mt352/dst/dvb-bt8xx be loaded automatically? is it up to
/etc/modprobe.conf logic to do this? or should the various dvb drivers be
forcing the loading of these modules rather than reporting undefined
symbols?
happy to be a tester for any proposed changes!
