29 | Configuring the media subsystem can be complex, as there are | |
30 | hundreds of drivers and other config options. | |
31 | ||
32 | This menu offers option that will help the Kernel's config | |
33 | system to hide drivers that are out of the scope of the | |
34 | user needs, and disabling core support for unused APIs. | |
35 | ||
36 | If not selected, all non-optional media core functionality | |
37 | needed to support media drivers will be enabled. Also, all | |
38 | media device drivers should be shown. | |

47 | By default, a media driver auto-selects all possible ancillary | |
48 | devices such as tuners, sensors, video encoders/decoders and | |
49 | frontends, that are used by any of the supported devices. | |
50 | ||
51 | This is generally the right thing to do, except when there | |
52 | are strict constraints with regards to the kernel size, | |
53 | like on embedded systems. | |
54 | ||
55 | Use this option with care, as deselecting ancillary drivers which | |
56 | are, in fact, necessary will result in the lack of the needed | |
57 | functionality for your device (it may not tune or may not have | |
58 | the needed demodulators). | |
