== 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 ==  {|width="100%" border="1" cellspacing="0" cellpadding="3" class="mediawiki sortable"!Task!Person!Status!Wiki Link |-|Koji Hub setup - PostgreSQL master|[[User:adaniel3|Arlene Daniel]]|In Progress - Goal of March 22|[[Fedora Arm Secondary Architecture/Koji Database|Koji Database]] |-|Koji Hub setup - Koji Hub configuration|[[User:Paul.W|Paul Whalen]],[[User:Sadiki|Sadiki Latty]]||[[Fedora Arm Secondary Architecture/Koji Hub|Koji Hub]] |-|Koji Hub setup - Certificates/security|[[User:Sadiki|Sadiki Latty]]||[[Fedora Arm Secondary Architecture/Koji Certificates|Koji Certificates]] |-|Koji Builder setup - Shared filesystem|[[User:Mashh|Mashfique Haque]]||[[Fedora Arm Secondary Architecture/Koji shared filesystem|Koji shared filesystem]] |-|Koji Builder setup - Koji Build Daemon|[[User:Dpcabra1|David Cabral]]||[[Fedora Arm Secondary Architecture/Koji Builders|Koji Builders]] |-|Performance - iSCSI vs. NFS vs. Local USB disk|[[User:Dmchisho|David Chisholm]]|In Progress|[[Fedora Arm Secondary Architecture/Storage performance|Storage Performance]] |-|Initial mock tests on ARM|Everyone|80%|[[Fedora ARM Secondary Architecture/Initial Mock Compilation Tests|Initial Mock Compilation Tests]]|-|Research and create image for F12 on OpenRD-Client|[[User:Paul.W|Paul Whalen]]|In progress| |-|NFS setup - HongKong to VMs|[[User:Dmchisho|David Chisholm]]|Completed|[[Fedora Arm Secondary Architecture/NFS Configuration|NFS Configuration]]
