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.
