Another DVB Question (CX23880)

Hey All,

Have a slack 2.6.18 box. When i enabled DVB for linux, none of the extra modules in gconfig where available (i.e. drivers for the video cards). For example, only 2 USB devices could be selected. The ones i think i needed, like the CX22700 based module, where disabled (only found them by clicking 'Show All Options'.

Do i need a later kernel? Why would these options be in there if i could select them (maybe from a 'make oldconfig'?)

If i've done something wrong, any pointers? below is what lspci shows my card to be...



Code:
02:07.0 Multimedia video controller: Conexant CX23880/1/2/3 PCI Video and Audio Decoder (rev 05)

Hi newio,

sorry I didn't understand which device you want to get working. You might although not need a new kernel. On linuxtv.org you can find the actual Linux DVB drivers that you can try to install on your kernel. See http://linuxtv.org/wiki/index.php/Ho...st_source_code

thankx, i checked out linuxtv, but it looks like the patch it applies to the kernel source is already in the kernel.

my issue is comes when i go to compile the modules using config. when i select Video For Linux (and Enable V4L API1), all the drivers listed under 'Video Capture Adapters' are greyed out (i.e. they are unselectable, using gconfig and xconfig). This is contrary to what i've read about in the how-to's. I've tried this in both 2.6.18.5 and 2.6.20.

the driver im after in particular is the cx88 driver.

No problem here (2.6.17.13) selecting the device with xconfig. If I load the module it seems to depend on these modules (part of lsmod output):

Code:
ir_common              23684  1 cx88xx
i2c_algo_bit            8584  1 cx88xx
video_buf              20356  1 cx88xx
btcx_risc               4104  1 cx88xx
tveeprom               13968  1 cx88xx
videodev                7168  1 cx88xx
i2c_core               17168  6 cx88xx,i2c_algo_bit,tveeprom,dvb_usb,nvidia,i2c_nforce2
I'm not sure what other stuff it might depend on that I have build right into my kernel, not as modules. Check your kernel config that you haven't disabled those mentioned above.

I guess the following sections called "Encoders and Decoders" and "V4L USB devices" are not that important, I compiled all available devices as modules as you can see. In case you don't have it but need it:
Code:

Post if you need another part of my kernel-config.

EDIT: fixed typo
