<title>Reference: Features</title>
|
|
|
|
<para>'Features' provide a mechanism for working out which packages
|
|
should be included in the generated images. Distributions can
|
|
select which features they want to support through the
|
|
<glossterm linkend='var-DISTRO_FEATURES'><link
|
|
linkend='var-DISTRO_FEATURES'>DISTRO_FEATURES</link></glossterm>
|
|
variable which is set in the distribution configuration file
|
|
(poky.conf for Poky). Machine features are set in the
|
|
<glossterm linkend='var-MACHINE_FEATURES'><link
|
|
linkend='var-MACHINE_FEATURES'>MACHINE_FEATURES</link></glossterm>
|
|
variable which is set in the machine configuration file and
|
|
specifies which hardware features a given machine has.
|
|
</para>
|
|
|
|
<para>These two variables are combined to work out which kernel modules,
|
|
utilities and other packages to include. A given distribution can
|
|
support a selected subset of features so some machine features might not
|
|
be included if the distribution itself doesn't support them.
