Nope, but I found it just before I went to bed. Reading through the
various Kconfig files, it turned out that there are 2 more requisits to
even being able to see it, its also dependent on RC_CORE which was not
enabled. So I fired off a build and went to bed knowing it would take
an hour as amanda was also running. Now I am about to reboot to test.
After the reboot, an lsmod shows the correct (I think, crosscheck this
list please) modules loaded:
gene@...ote:~/src/linux-3.13.5/drivers/media/rc$ lsmod |grep cx
cx8802 11232 0
cx8800 23126 0
cx88xx 69224 2 cx8802,cx8800
v4l2_common 3438 3 tuner,cx8800,cx88xx
videodev 88190 4 tuner,cx8800,cx88xx,v4l2_common
tveeprom 11057 1 cx88xx
btcx_risc 2799 3 cx8802,cx8800,cx88xx
videobuf_dma_sg 7044 3 cx8802,cx8800,cx88xx
videobuf_core 13768 5 videobuf_dvb,cx8802,cx8800,cx88xx,videobuf_dma_sg
i2c_algo_bit 4647 2 cx88xx,nouveau
i2c_core 17109 12 or51132,tuner,cx8800,cx88xx,v4l2_common,videodev,tveeprom,i2c_nforce2,nouveau,drm_kms_helper,drm,i2c_algo_bit
But kaffeine can't find it. The tv configure pulldown did show it, ghosted
like something else has a lock on it, so I removed it thinking it might
rescan and find it, but no such luck. And the kde manual for kaffeine
seems to be on the missing list.
There is evidence in the dmesg that too many tuners are enabled, and no
evidence of the /lib/firmware/dvb-fe-or51132-vsb.fw being applied. It
has been powered down several times, and it needs that firmware
reloaded each time, and I've forgot how to do that.
I know it worked but poorly with kernel 2.6.32-132-RTAI, so thats the
next step, reboot to that to dbl-check.
Thanks Ilia.
Cheers, Gene
