1 | How to get the bt8xx cards working |

4 | 1) General information |
5 | ====================== | |

8abe58ae UB |
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: | |

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" | |
1da177e4 | 23 | |
afb758c4 UB |
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. | |

29 | 2) Loading Modules |
30 | ================== | |

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. | |
8abe58ae | 35 | People running udev please see Documentation/dvb/udev.txt. |
2d6e7322 | 36 | |
8abe58ae | 37 | In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary: |

39 | 2a) Running TwinHan and Clones |
40 | ------------------------------ | |
2d6e7322 | 41 | |
8abe58ae | 42 | $ modprobe bttv card=113 |
8abe58ae | 43 | $ modprobe dst |
2d6e7322 | 44 | |
8abe58ae | 45 | Useful parameters for verbosity level and debugging the dst module: |
2d6e7322 | 46 | |
8abe58ae UB |
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 | |
2d6e7322 | 54 | |
8abe58ae UB |
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. | |

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 | |
