27To enable the cedartrail layer, add the cedartrail MACHINE to local.conf: 31The meta-cedartrail layer contains support for two different machine
32configurations. These configurations are identical except for the fact
33that the one prefixed with 'cedartrail' makes use of Intel' proprietary
34PowerVR Graphics/Media drivers to enable Graphics and Media acceleration
35in the processor, while the one prefixed with 'cedartrail-nonopvr' uses
36non-accelerated graphics driver (VESA).

38If you want to enable the layer that supports Power VR graphics add the

43Power VR Graphics user-space driver binaries are covered by a

110Video and Music Samples
111-----------------------
112This BSP includes recipes to download Ogg format video and
113music files that can be played-back with the Video and music players
114included in the sato images. The sample files are installed in
115/home/Music and /home/Videos directories.

117
118Adding Glxgears to image
119-------------------------
120Glxgears can be added to the generated image by adding "debug-tweaks"
121option to the extra image features variable in the default local.conf
122before building the BSP.
123
124e.g. to add Glxgears, locate the following line in local.conf
125EXTRA_IMAGE_FEATURES = "debug-tweaks"
126
127and change above line to..
