Automatically load ittv drivers at startup

cdhgee · 07-26-2005, 05:33 PM

I've got an Hauppauge WinTV PVR 150 tv card, which works very well with the ivtv 0.3.x drivers. The only thing I can't get to work is that they won't load automatically at startup - I've googled a bit and it seems all the advice out there is to add stuff to /etc/modprobe.conf, which I've done thus:

Code:

#TV Card settings

alias char-major-81 videodev
alias char-major-81 ivtv
alias char-major-81-0 ivtv
alias char-major-61 lirc_i2c
options tveeprom debug=2
options msp3400 debug=1
options cx25840 i2c_enable=1 debug=2 cardtype=0
options tuner type=38 pal=i
options ivtv ivtv_debug=255 ivtv_std=2 cardtype=6
install ivtv /sbin/modprobe --ignore-install ivtv
install lirc_i2c /sbin/modprobe ivtv; /sbin/modprobe --ignore-install lirc_i2c

As I understand it, this should mean that the first time /dev/video0 is accessed, the ivtv drivers should automatically load. However this isn't happening - because /dev/video0 doesn't exist until the ivtv stuff loads.

I'm wondering if it's something to do with the fact that the system doesn't know which driver is associated with the TV card; here's an extract from /etc/sysconfig/hwconf (very similar to lspci, but it shows which drivers each device is using):

Code:

class: CAPTURE
bus: PCI
detached: 0
driver: unknown
desc: "Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder"
vendorId: 4444
deviceId: 0016
subVendorId: 0070
subDeviceId: 8003
pciType: 1
pcidom:    0
pcibus:  0
pcidev:  8
pcifn:  0

If it doesn't know which driver it's supposed to be using, kudzu probably can't pick an appropriate module to load. Am I interpreting this correctly? Is this fixable?

Any suggestions?

I have the exact same problem what did you do to resolve this issue? or do you still have it.

I am using FC4 and am trying to get lirc working correctly. I've used the jarod's tutorial but it does not seem to help me. When my box boots the service lircd kind of starts then hangs. From a fresh boot up if i type in "irw", it returns me to a command line instead of reading my remote.
If i stop the service:
# service lircd stop
then I start the lirc_i2c module:
# modprobe lirc_i2c
then restart the service:
# service lircd start
That makes everything happy and my system works again. The remote functions as needed and I couldn't be happier. But how in the world do i get it to boot correctly without doing all those steps.

Heres my hardware:
P4 1.7Ghz
1GB Ram
2 40GB HD's
PVR-150
Asus Mobo

Heres a copy of my modprobe.conf:

alias eth0 sis900
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0
remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
alias usb-controller ehci-hcd
alias usb-controller1 ohci-hcd
# nvidia kernel module
alias char-major-195 nvidia-1_0-8178
alias nvidia nvidia-1_0-8178
# ivtv (PVR-150)
alias char-major-81 ivtv
alias char-major-81-0 ivtv
alias tveeprom tveeprom-ivtv
alias tuner tuner-ivtv
alias msp3400 msp3400-ivtv
alias tda9887 tda9887-ivtv
# lirc module refrence
alias char-major-61 lirc_i2c
install lirc_i2c /sbin/modprobe ivtv; /sbin/modprobe --ignore-install lirc_i2c

If anyone can help the two of us it would be greatly appreciated

awing_pilot,
Well, the proper way to do this would be to find out why it is not working, and fix it.
The quick-and-dirty solution would be to put those commands at the end of the file /etc/rc.d/rc.local, where they will be executed after everything else has been done, but before you are offered a login. I'll let you guess which option I'd go for!

FWIW I have a PVR-150 (PAL) and have not managed to get it working at all, with either Knoppmyth 5A16, or the current MythDora. It is correctly recognised as a Tuner=38, PAL card and I seem to be able to tune it, but all I see is static, and there's no sound at all with alsa. I think this might be a long-term project!

my pvr works wonderfully, unfortunately i don't know much about how different the pal setup is from NTSC. However your idea did work to perfection. Been looking for the "right" solution for a few days now no one had any advice, so yours works and now i don't have to worry about it till something else breaks i guess. Thank you so much for your assistance
