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 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.
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.
We're going to set up a Koji build system for ARM. Initially this will be based on the CDOT system HongKong. Initial ARM builders will use QEMU emulation, which will be replaced by ARM Hardware when it arrives.
Notes on Koji status at 2010-04-17 15:15:
- the test target
dist-f13testis up and running
- scratch builds can be performed
- many of the VMs require NFS configuration -- they have been disabled temporarily. After setting up NFS on your VM, please enable it (or ping someone on IRC to enable it for you).
