== Fedora Secondary Architecture Architectures ==

[http://fedoraproject.org Fedora supports two primary architectures] is an [http:* i386 - 32-bit Intel/AMD-compatible* x86_64 /opensource.org open source] community that produces the [http://get.fedoraproject.org Fedora Linux distribution] - 64-bit Intel/AMD-compatiblea complete operating system (and more) consisting of thousands of software packages. This software is available free of charge complete with the source code, so anyone can use, distribute, and modify it to meet their needs.

The Fedora distribution supports two primary architectures; these are the primary targets for the packages in Fedora:* i386 - 32-bit Intel/AMD - the chips that power most 32-bit computers, laptops, and netbooks* x86_64 - 64-bit Intel/AMD - the chips that power most 64-bit computers and laptops There are also a number of secondary archsarchitechtures, maintained by various groups within the larger Fedora community:* arm '''ARM''' - A widely-used, low-power processor family commonly used for embedded and mobile applications, including cellphones and tablets

The [[:fedora:Architectures/ARM architecture is increasingly important, but has fallen behind the other secondary archs in terms of update frequency, number of packages successfully built, transparency of process, and integration with the other |Fedora build processesARM Secondary Architecture]] project supports Fedora on ARM processors.

ARM chips are the most popular CPU produced -- approximately 1.6 in excess of 7 billion are being made each year, or about a million an hour. These are being sold under a number of different brand names (ARM, StrongARM, XScaleArmada, Cortex, OMAP, Sheeva, Snapdragon, XScale) by a number of different manufacturers. Most of these are going into cellphones, but hundreds of millions are being used in other devices such as routers, NAS boxes, embedded controllers, tablets, and netbooks. ARM processors are used in emerging ''hyperscale'' energy-efficient compute systems based on [http://calxeda.com Calxeda] and [http://marvell.com Marvell] processors. In addition, ARM processors are used on:* [http://www.laptop.org One Laptop Per Child] (OLPC) computers, model XO-1.75 and higher (Fedora is used on the XO units)* the [http://raspberrypi.org Raspberry Pi], [http://apc.io APC], and other under-$100 "hackputers"* [http://plugcomputer.org Plug Computers] == Objective ==

The new One Laptop Per Child (OLPC) hardware, model XO-1.75, will use an ARM processor. Since Fedora Seneca is used on supporting the XO units, having Fedora ARM initiative by hosting and managing a reliable ARM [[:fedora:Koji|Koji]] build of Fedora farm that shadows the primary architectures, so that every package built for the primary architectures (including updates) is going to become increasingly importantbe built for ARM.

We're going to set up a Koji build system for ARM== Status == * Currently building F20. Initially this will be based on * See the [[CDOT Development SystemsFedora ARM Secondary Architecture/ARM hardware|CDOT systemARM Hardware]] [http://hongkong.proximity.on.ca/ HongKong]. Initial ARM builders will use QEMU emulation, which will be replaced by ARM page for details of the build farm hardware when it arrives.
