Bugs
This is not tested yet:
Get firmware, old option
In /usr/src/linux/drivers/media/video/saa7134/saa7134-dvb.c, line 873, struct tda1004x_config philips_tiger_config change the entry
.request_firmware = NULL
to
.request_firmware = philips_tu1216_request_firmware
Run /usr/src/linux/Documentation/dvb/get_dvb_firmware and copy the dvb-fe-tda10046.fw to /lib/firmware
modprobe saa7134 card=78 gpio_tracking=1
See http://www.spinics.net/lists/vfl/msg27672.html
Get firmware, new option
The Mercurial version "emerge v4l-dvb-hg" gives the card a proper card number of 112. The card can then be brought up with
modprobe saa7134 card=112 tuner=54 gpio_tracking=1 i2c_scan=1
You may also need to
modprobe saa7134-dvb modprobe saa7134-alsa
This works now but may not continue to do so.
lspci -v
Module Options
For analog signal (autodetected?):
saa7134 card=78 tuner=54
