Fedora Architectures

Fedora is an open source community that produces the Fedora Linux distribution -- a 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 architechtures, maintained by various groups within the larger Fedora community:

  • ARM - A widely-used, low-power processor family commonly used for embedded and mobile applications, including cellphones and tablets
  • 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

The Fedora ARM Secondary Architecture project supports Fedora on ARM processors.

ARM Processors

ARM chips are the most popular CPU produced -- 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.

ARM processors are used in emerging hyperscale energy-efficient compute systems based on Calxeda and Marvell processors.

In addition, ARM processors are used on:


Seneca is supporting the Fedora ARM initiative by hosting and managing a Koji 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 Buildsystem is accessible through a web interface and through the koji command-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 Fedora Account System (fas2).


  • Currently building F20.
