PixelView XCapture - Conexant CX23881 Chipset

[Graham Finlayson]

I have been using the pre-alpha CX88 driver to see how far I could get with 
this card. I have successfully loaded the module and get output from v4l- 
conf and v4l-info. However, when I try to use xawtv or tvtime, I completely 
hang up my system. I am not too worried about this as that is what pre- 
alpha means, but I have been unable to obtain any additional debug output 
to determine whether this is a problem with the driver, or whether there is 
some other problem with my system (e.g. IRQ conflicts or similar) that is 
causing the problem. I was trying to specify options for the driver in the 
/etc/modules.conf file, but these did not seem to be recognised by the 
driver.

The /etc/modules.conf file has the following section, which I am not really 
sure is correct, as I don't know the difference between the cx8800 and 
cx88xx drivers.

alias char-major-81     videodev
alias char-major-81-0   cx88xx
options cx88xx  debug=1 card=1
alias /dev/v4l  cx88xx
I was also slightly surprised the the output from v4l-info was 
"UNKNOWN/GENERIC" as the PCI device identifies the chip as Conexant, but 
that is probably just showing my ignorance

general info
   VIDIOC_QUERYCAP
       driver                  : "cx8800"
       card                    : "UNKNOWN/GENERIC"
       bus_info                : "PCI:01:06.0"
       version                 : 0.0.1
       capabilities            : 0x1000001 [VIDEO_CAPTURE,READWRITE]
 Bus  1, device   6, function  0:
   Multimedia video controller: PCI device 14f1:8800 (Conexant) (rev 3).
     IRQ 5.
     Master Capable.  Latency=32.  Min Gnt=20.Max Lat=55.
     Non-prefetchable 32 bit memory at 0xe6000000 [0xe6ffffff].
So I am looking for advice on how to get more debug output so that I can 
pass this on to make sure that the driver eventually works with this card. 
I don't have enough experience to try to do any development on the driver, 
but I am willing to read any documents and do experiments to add this card 
to this driver.
