50 | The Yocto Project is an open-source collaboration project whose | ||
51 | focus is for developers of embedded Linux systems. | ||
52 | Among other things, the Yocto Project uses an | ||
53 | <link linkend='build-system-term'>OpenEmbedded build system</link>. | ||
54 | The build system, which is based on the OpenEmbedded (OE) project and | ||
55 | uses the | ||
56 | <link linkend='bitbake-term'>BitBake</link> tool, constructs complete | ||
57 | Linux images for architectures based on ARM, MIPS, PowerPC, x86 and | ||
58 | x86-64. | ||
59 | <note> | ||
60 | Historically, the OpenEmbedded build system, which is the | ||
61 | combination of BitBake and OE components, formed a reference | ||
62 | build host that was known as | ||
63 | "<link linkend='poky'>Poky</link>" (<emphasis>Pah</emphasis>-kee). | ||
64 | The term "Poky", as used throughout the Yocto Project Documentation | ||
65 | set, can have different meanings. | ||
66 | </note> | ||
67 | The Yocto Project provides various ancillary tools for the embedded | ||
68 | developer and also features the Sato reference User Interface, which | ||
69 | is optimized for stylus-driven, low-resolution screens. | ||

80 | Here are some highlights for the Yocto Project: | ||
81 | </para> | ||
82 | |||
83 | <itemizedlist> | ||
84 | <listitem><para> | ||
85 | Provides a recent Linux kernel along with a set of system | ||
86 | commands and libraries suitable for the embedded | ||
87 | environment. | ||
88 | </para></listitem> | ||
89 | <listitem><para> | ||
90 | Makes available system components such as X11, GTK+, Qt, | ||
91 | Clutter, and SDL (among others) so you can create a rich user | ||
92 | experience on devices that have display hardware. | ||
93 | For devices that do not have a display or where you wish to | ||
94 | use alternative UI frameworks, these components need not be | ||
95 | installed. | ||
96 | </para></listitem> | ||
97 | <listitem><para> | ||
98 | Creates a focused and stable core compatible with the | ||
99 | OpenEmbedded project with which you can easily and reliably | ||
100 | build and develop. | ||
101 | </para></listitem> | ||
102 | <listitem><para> | ||
103 | Fully supports a wide range of hardware and device emulation | ||
104 | through the Quick EMUlator (QEMU). | ||
105 | </para></listitem> | ||
106 | <listitem><para> | ||
107 | Provides a layer mechanism that allows you to easily extend | ||
108 | the system, make customizations, and keep them organized. | ||
109 | </para></listitem> | ||
110 | </itemizedlist> | ||
111 | |||
112 | <para> | ||
113 | You can use the Yocto Project to generate images for many kinds | ||
114 | of devices. | ||
115 | As mentioned earlier, the Yocto Project supports creation of | ||
116 | reference images that you can boot within and emulate using QEMU. | ||
117 | The standard example machines target QEMU full-system | ||
118 | emulation for 32-bit and 64-bit variants of x86, ARM, MIPS, and | ||
119 | PowerPC architectures. | ||
120 | Beyond emulation, you can use the layer mechanism to extend | ||
121 | support to just about any platform that Linux can run on and that | ||
122 | a toolchain can target. | ||
123 | </para> | ||
124 | |||
125 | <para> | ||
126 | Another Yocto Project feature is the Sato reference User | ||
127 | Interface. | ||
128 | This optional UI that is based on GTK+ is intended for devices with | ||
129 | restricted screen sizes and is included as part of the | ||
130 | OpenEmbedded Core layer so that developers can test parts of the | ||
131 | software stack. | ||
132 | </para> | ||
133 | |||
134 | <para> | ||
135 | While the Yocto Project does not provide a strict testing framework, | ||
136 | it does provide or generate for you artifacts that let you perform | ||
137 | target-level and emulated testing and debugging. | ||
138 | Additionally, if you are an | ||
139 | <trademark class='trade'>Eclipse</trademark> IDE user, you can | ||
140 | install an Eclipse Yocto Plug-in to allow you to develop within that | ||
141 | familiar environment. | ||
142 | </para> | ||
143 | |||
144 | <para> | ||
145 | By default, using the Yocto Project to build an image creates a Poky | ||
146 | distribution. | ||
147 | However, you can create your own distribution by providing key | ||
148 | <link link='metadata'>Metadata</link>. | ||
149 | A good example is Angstrom, which has had a distribution | ||
150 | based on the Yocto Project since its inception. | ||
151 | Other examples include commercial distributions like | ||
152 | <ulink url='https://www.yoctoproject.org/organization/wind-river-systems'>Wind River Linux</ulink>, | ||
153 | <ulink url='https://www.yoctoproject.org/organization/mentor-graphics'>Mentor Embedded Linux</ulink>, | ||
154 | <ulink url='https://www.yoctoproject.org/organization/enea-ab'>ENEA Linux</ulink> | ||
155 | and <ulink url='https://www.yoctoproject.org/ecosystem/member-organizations'>others</ulink>. | ||
156 | See the "<ulink url='&YOCTO_DOCS_DEV_URL;#creating-your-own-distribution'>Creating Your Own Distribution</ulink>" | ||
