Fedora

Fedora, an open source operating system using RPM-based, built on top of the Linux kernel. It is developed and maintained by a community-support known as the Fedora Project which is sponsored by Red Hat. The Fedora Project's mission is "To lead the advancement of free and open source software and content as a collaborative commuinty." Fedora's main aim is to be a leader in the use and distrbution on software designed as open source.

The ARM Architecture

ARM chips are the most popular CPU produced -- approximately 1.6 billion are being made each year. 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 is increasingly important.


Supported Architecture

Fedora supports two primary architectures: 

   i386 - 32-bit Intel/AMD-compatible
   x86_64 - 64-bit Intel/AMD-compatible

There are also a number of secondary archs: 

   arm - A widely-used, low-power processor family commonly used for embedded and mobile applications
   ia64 – Itanium
   pa-risc - HP Precision Architecture
   ppc - 32-bit Power PC
   ppc64 - 64-bit Power PC
   s390 - IBM mainframes (including z90 and z9)
   sparc - Sun RISC architecture

Results

At the close of the semester we currently have a functional Koji Build system. The Koji Hub is successfully dispatching packages to the Koji builder Daemons and Kojira is creating new repositories for use with the ARM architecture. Eight VM's and the Open-RD Client are online and are listed as Ready and Enable using the Koji command line tool and the web interface through Koji Web.
