Introduction
Fedora Secondary 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
The 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 processes.
ARM Processors
ARM chips are the most popular CPU produced -- approximately 5 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.
The 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.
Goal
To support the Fedora ARM initiative by creating and managing a Koji build farm that will koji-shadow the primary architectures, so that every package built for the primary architectures (including updates) will be built for ARM.
Plan
Initial Plan
We're going to set up a Koji build system for ARM. Initially this will be based on the CDOT system HongKong. We have 7 hardware ARM builders at present (see ARM Hardware).
Status
As of 2010-08-14: The Fedora ARM Koji system is up and running; it is currently building F13 under the supervision of Paul Whalenn and Chris Tyler.
