ARMv8 Support Analysis

Project Description

Many Fedora packages contain assembley code for performance optimization or platform-specific support. Assembley code is very processor-specific. When assembley code is not present for a specific architecture, either the package will not build on that architecture, or other code (typically C) which is not processor-specific is used instead.

This project involves analyzing Fedora packages to determine which ones contain assembly code, and determining whether the package will probably build on the upcoming ARMv8 64-bit architecture.

Expected outcome: An analysis of part of the Fedora package set to predict ARMv8 build outcomes.

Maximum number of students: 6 (each taking part of the Fedora package set)

Skills required: packaging, scripting, writing

Resources: Chris Tyler (ctyler), Jon Masters (jonmasters)

Project Plan

Tracking mechanism (bugzilla, trac, github, ...):

Key contacts:

Goals for each release and plans for reaching those goals:

• 0.1
  • Build initial script to identify assembly code inside fedora packages
  • Make a basic database with the initial data
• 0.2
  • Generate script that will distinguish between Arch and Platform specific assembly code
  • Get/make koji connector to get additional data
  • Make a better databse with the newer set dataset
• 0.3
  • Predict the list of Fedora packages that may or may not build on ARMv8
