[linux-dvb] Problem working with more than 4 cards...

["Aurelian Pop" <puiu@cs.tut.fi>]

I have 3 dvbt and 2 dvbs cards on my system, (working with devfs since yesterday, thanks to you guyz :) ).
To make the drivers work, I changed 2 things:

MAX_NUM_DVB from 4 to 6 (dvb.h)
SAA7146_MAX_DEVICES from 4 to 6 (saa7146_core.h)

Do not ask me why I change THESE 2 values... it seemed to me from their name, that they could have something to do with the numbers of cards supported, and I changed them. I do not know the drivers in detail, so if I changed them to wrong values be gentle with me... :)

The drivers load/unload correctly from memory, and the /dev/dvb/... device tree is created correctly, like below:


[root@server1 driver]# ls /dev/dvb/*
/dev/dvb/card0:
demux0  dvr0  frontend0  net0

/dev/dvb/card1:
demux0  dvr0  frontend0  net0

/dev/dvb/card2:
demux0  dvr0  frontend0  net0

/dev/dvb/card3:
demux0  dvr0  frontend0  net0  sec0

/dev/dvb/card4:
demux0  dvr0  frontend0  net0  sec0


So it's correct: 3 dvbt, and 2 dvbs.
The output of lsmod gives:

AFAIK, this output seems corect.
Anyway... there is a problem.
Querying the drivers through the frontend device, I get in the FrontendInfo structure, in the .type field: 2 - four times and 0 - one time.
This means the drivers tell me I have 4 dvbt (2 - four times) and 1 dvbs (0 one time) cards, wich is wrong... (I have 3t and 2s)
Again, if I try to force the card which I know has to be dvbs instead of dvbt, I get error when I open the sec device (behaviour consistent with cards that aren't dvbs), even though that sec device exists in devfs.

Any suggestions from the driver developpers?
Maybe I changed the drivers files wrong or anything else (like irq conflicts) ??

Any reply would be appreciated...
Thanks,
Aurelian
