documentation: Rename of poky-ref-manual folder to ref-manual.
Changing the folder that holds the YP Reference Manual to be
"ref-manual". This will help with confustion over the manual's
intended purpose.

| 25 | Features provide a mechanism for working out which packages | ||
| 26 | should be included in the generated images. | ||
| 27 | Distributions can select which features they want to support through the | ||
| 28 | <code class="filename"><a class="link" href="ref-variables-glos.html#var-DISTRO_FEATURES" title="DISTRO_FEATURES">DISTRO_FEATURES</a></code> | ||
| 29 | variable, which is set in the <code class="filename">poky.conf</code> distribution configuration file. | ||
| 30 | Machine features are set in the | ||
| 31 | <code class="filename"><a class="link" href="ref-variables-glos.html#var-MACHINE_FEATURES" title="MACHINE_FEATURES">MACHINE_FEATURES</a></code> | ||
| 32 | variable, which is set in the machine configuration file and | ||
| 33 | specifies the hardware features for a given machine. | ||
| 34 | </p> | ||
| 35 | <p> | ||
| 36 | These two variables combine to work out which kernel modules, | ||
| 37 | utilities, and other packages to include. | ||
| 38 | A given distribution can support a selected subset of features so some machine features might not | ||
| 39 | be included if the distribution itself does not support them. | ||
| 40 | </p> | ||
| 41 | <p> | ||
| 42 | One method you can use to determine which recipes are checking to see if a | ||
| 43 | particular feature is contained or not is to <code class="filename">grep</code> through | ||
| 44 | the metadata for the feature. | ||
| 45 | Here is an example that discovers the recipes whose build is potentially | ||
| 46 | changed based on a given feature: | ||
| 47 | </p> | ||
| 48 | <pre class="literallayout"> | ||
| 49 | $ cd $HOME/poky | ||
| 50 | $ git grep 'contains.*MACHINE_FEATURES.*<feature>' | ||
| 51 | </pre> | ||
| 52 | <p> | ||
| 53 | </p> | ||
| 54 | <p> | ||
| 55 | This chapter provides a reference of shipped machine and distro features | ||
| 56 | you can include as part of the image, a reference on image types you can | ||
| 57 | build, and a reference on feature backfilling. | ||
