== 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 there's a lot more that could be done 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, Armada, 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. One Laptop Per Child (OLPC) computers, model XO-1.75, use an ARM processor. Since Fedora is used on the XO units, having a reliable ARM build of Fedora will become increasingly important. = Plan = == Initial Plan == We're going to set up a Koji build system for ARM. Initially this will be based on the [[CDOT Development Systems|CDOT system]] [http://hongkong.proximity.on.ca/ HongKong]. Initial ARM builders will use QEMU emulation, which will be replaced by ARM hardware when it arrives. == Current Tasks == 

|-In addition, ARM processors are used on:|Koji Hub setup * [http://www.laptop.org One Laptop Per Child] (OLPC) computers, model XO- PostgreSQL master1.75 and higher (Fedora is used on the XO units)|* the [http://raspberrypi.org Raspberry Pi], [Userhttp:adaniel3|Arlene Daniel]//apc.io APC]|In Progress , and other under- Goal of March 22$100 "hackputers"|* [http://plugcomputer.org Plug Computers]

|-|Koji Hub setup - Certificates/security|Seneca is supporting the Fedora ARM initiative by hosting and managing a [[User:Sadikifedora:Koji|Sadiki LattyKoji]]||build farm that shadows the primary architectures, so that every package built for the primary architectures (including updates) is to be built for ARM.

|-|The [[Fedora ARM Koji Builder setup Buildsystem]] is accessible through a [http://arm.koji.fedoraproject.org web interface] and through the koji command- Shared filesystem|line tools provided as part of Fedora. Anyone with a Fedora account is welcome to build packages on it; if you do not already have an account wish to make use of the build system you can sign up using the [[Userhttps:Mashh|Mashfique Haque]//admin.fedoraproject.org/accounts/ Fedora Account System (fas2)]||.
