Configuring the media subsystem can be complex, as there are

hundreds of drivers and other config options.
|

This menu offers option that will help the Kernel's config
|
|
system to hide drivers that are out of the scope of the
|
|
user needs, and disabling core support for unused APIs.
|

If not selected, all non-optional media core functionality

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

have regressions.
