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.

46 help
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).
59
60 If unsure say Y.

144 These drivers should not be used on production kernels, but
145 can be useful on debug ones. This option enables several dummy drivers
146 that simulate real hardware. Very useful to test userspace
147 applications and to validate if the subsystem core doesn't
148 have regressions.
149
150 Say Y if you want to use some virtual test driver.
151
152 In case of doubts, say N.
