I am working with WinTV NOVA-S-Plus card and WinTV PVR-500 card in RHEL 4.4 machine.
I am using kernel 2.6.12.
For WinTV NOVA-S-plus card i have used v4l-dvb drivers.
For PVR-500 card i have used ivtv-0.4.9 drivers.
After compiling and installing these two drivers, i tried the following steps to load the drivers.
1. for NOVA-S-Plus card
modprobe tveeprom
modprobe cx24123
modprobe cx8800
modprobe cx8802
modprobe cx88xx
modprobe cx88-dvb
2. for PVR-500 card
depmod -a
modprobe tveeprom
modprobe ivtv
U can see the tveeprom is loaded twice. becos both the drivers has its own tveeprom
for nova-s-plus card it is in /lib/modules/2.6.12/kernel/drivers/media/video/ directory
for pvr-500 card it is in /lib/modules/2.6.12/ivtv/ directory.
If i do load the driver for nova-s-plus card it load it properly and dvb device is getting registered properly.
xawtv -hwscan detects the card and shows card details.
After this if i load the driver for pvr card
modprobe ivtv gives the following error
FATAL: Error inserting ivtv (/lib/modules/2.6.12/kernel/drivers/media/video/ivtv/ivtv.ko): Unknown symbol in module, or unknown parameter (see dmesg)
dmesg shows the following
ivtv: disagrees about version of symbol video_unregister_device
ivtv: Unknown symbol video_unregister_device
ivtv: disagrees about version of symbol video_device_alloc
ivtv: Unknown symbol video_device_alloc
ivtv: disagrees about version of symbol video_register_device
ivtv: Unknown symbol video_register_device
ivtv: disagrees about version of symbol video_device_release
ivtv: Unknown symbol video_device_release
If do the reverse procedure ie loading ivtv first and then load v4l dvb drivers
PVR card is detected properly but while loading NOVA-S-plus card drivers
modprobe cx88-dvb gives the following error
modprobe cx88-dvb

cx88_dvb: Unknown symbol cx88_boards
cx88_dvb: Unknown symbol cx8802_buf_queue
cx88_dvb: Unknown symbol cx8802_suspend_common
From the result what i understood is both drivers have a module called tveeprom.ko and that's where the problem starts.
so please tell the solution for both the cards to work simultaneously.
Thanks in advance for ur help
Regards,
Thiru.
