1	How to get the bt8xx cards working
2	==================================
3	
4	1) General information
5	======================
6	
7	This class of cards has a bt878a as the PCI interface, and require the bttv driver
8	for accessing the i2c bus and the gpio pins of the bt8xx chipset.
9	Please see Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge:
10	
11	Compiling kernel please enable:
12	a.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Enable Video for Linux API 1 (DEPRECATED)"
13	b.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Video Capture Adapters" => "BT848 Video For Linux"
14	c.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices" => "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards"
15	
16	Please use the following options with care as deselection of drivers which are in fact necessary
17	may result in DVB devices that cannot be tuned due to lack of driver support:
18	You can save RAM by deselecting every frontend module that your DVB card does not need.
19	
20	First please remove the static dependency of DVB card drivers on all frontend modules for all possible card variants by enabling:
21	d.) "Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
22	 => "DVB for Linux" "DVB Core Support" "Load and attach frontend modules as needed"
23	
24	If you know the frontend driver that your card needs please enable:
25	e.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
26	 => "DVB for Linux" "DVB Core Support" "Customise DVB Frontends" => "Customise the frontend modules to build"
27	 Then please select your card-specific frontend module.
28	
29	2) Loading Modules
30	==================
31	
32	Regular case: If the bttv driver detects a bt8xx-based DVB card, all frontend and backend modules will be loaded automatically.
33	Exceptions are:
34	- Old TwinHan DST cards or clones with or without CA slot and not containing an Eeprom.
35	People running udev please see Documentation/dvb/udev.txt.
36	
37	In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary:
38	
39	2a) Running TwinHan and Clones
40	------------------------------
41	
42		$ modprobe bttv card=113
43		$ modprobe dst
44	
45	Useful parameters for verbosity level and debugging the dst module:
46	
47	verbose=0:		messages are disabled
48		1:		only error messages are displayed
49		2:		notifications are displayed
50		3:		other useful messages are displayed
51		4:		debug setting
52	dst_addons=0:		card is a free to air (FTA) card only
53		   0x20:	card has a conditional access slot for scrambled channels
54	
55	The autodetected values are determined by the cards' "response string".
56	In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
57	For bug reports please send in a complete log with verbose=4 activated.
58	Please also see Documentation/dvb/ci.txt.
59	
60	2b) Running multiple cards
61	--------------------------
62	
63	Examples of card ID's:
64	
65	Pinnacle PCTV Sat:		 94
66	Nebula Electronics Digi TV:	104
67	pcHDTV HD-2000 TV:		112
68	Twinhan DST and clones:		113
69	Avermedia AverTV DVB-T 771:	123
70	Avermedia AverTV DVB-T 761:	124
71	DViCO FusionHDTV DVB-T Lite:	128
72	DViCO FusionHDTV 5 Lite:	135
73	
74	Notice: The order of the card ID should be uprising:
75	Example:
76		$ modprobe bttv card=113 card=135
77	
78	For a full list of card ID's please see Documentation/video4linux/CARDLIST.bttv.
79	In case of further problems please subscribe and send questions to the mailing list: linux-dvb@linuxtv.org.
80	
81	2c) Probing the cards with broken PCI subsystem ID
82	--------------------------------------------------
83	There are some TwinHan cards that the EEPROM has become corrupted for some
84	reason. The cards do not have correct PCI subsystem ID. But we can force
85	probing the cards with broken PCI subsystem ID
86	
87		$ echo 109e 0878 $subvendor $subdevice > \
88			/sys/bus/pci/drivers/bt878/new_id
89	
90	109e: PCI_VENDOR_ID_BROOKTREE
91	0878: PCI_DEVICE_ID_BROOKTREE_878
