I'm guessing that this will end up being a udev and not an ivtv
question, but:
My system has one pvr-150 and one pvr-500 (very sadly, one with samsung
tuners) - one of them (pvr-500, first tuner) is hooked to my cable box
for digital/premium content, the others direct to analog cable. I've
got udev rules to set up aliases according to physical location (pci
slot / pvr-500 unit) - the rules always test fine and never create the
wrong aliases, but they sometimes don't all fire, leaving me with one or
more tuners missing via the aliases I'm trying to set up.
Suggestions?
Many thanks!
ubuntu edgy
kernel 2.6.17-11
udev 0.93
ivtv 0.7.4
My udev (0.93) rules:
# pvr150
DRIVER=="ivtv", SYSFS{name}=="ivtv? encoder MPEG", ID=="0000:04:09.0",
SYMLINK+="pci/0/mpeg0"
#pvr500
DRIVER=="ivtv", SYSFS{name}=="ivtv? encoder MPEG", ID=="0000:05:08.0",
SYMLINK+="pci/1/mpeg0"
#pvr500, unit 2. These ought to be pci/1
DRIVER=="ivtv", SYSFS{name}=="ivtv? encoder MPEG", ID=="0000:05:09.0",
SYMLINK+="pci/1/mpeg1"
Symptom:
- all /dev/video[012] always appear, though in random order (/dev/video0
can point to any of the tuners)
- the /dev/pci/[01]/mpeg[01] aliases may or may not appear on any
particular boot - this boot I got /dev/pci/0/mpeg0 and /dev/pci/1/mpeg0
(no 1/mpeg1). last boot I got pci/1/mpeg0 and pci/1/mpeg1 (not 0/mpeg0).
/var/log/messages for this boot's missing unit:
