Supporting Architectures Above armv5tel
Project Description
The armv5tel architecture version is supported by some common devices such as the Marvell Feroceon processors used in most plug computers. However, later versions of the architecture support advanced features, and using armv5tel code on those processors may result in suboptimal performance.
This project will research ways that Fedora-ARM could support higher processor versions effectively without recompiling the entire Fedora package universe -- for example, by providing an armv7 + hardfp glibc and kernel. This involves performance testing across multiple devices.

Project Details
This project aims to test the significance of technologies that exist in ARMv7 architecture by conducting different benchmark techniques. This project also covers performance comparison between ARMv5 and ARMv7.
ARMv7 Technologies:
There are currently 2 ARMv7 (beagleboard & beagleboard XM) builders in the Fedora ARM farm. Unfortunately, these builders are running builds on ARMv5tel architecture; which means optimum performance is not achieved.
Project Plan
Goals for each release:
- 0.1 Run a benchmark program specifically designed not to use much of
glibc - 0.2
- 0.3
Things to learn
-Ways of benchmarking ARM processors
-gcc install options
-Compiling kernel and glibc
-Familiarization with ARM hardware
