1. Preface

The broad design principles are:

• keep it reasonable
  • We cannot rewrite the complete server
  • We don't want to re-invent the wheel
• keep it modular
  • As many things as possible should go into modules
  • The basic loader binary should be minimal
  • A clean design with well defined layering is important
  • DDX specific global variables are a nono
  • The structure should be flexible enough to allow future extensions
  • The structure should minimize duplication of common code
• keep important features in mind
  • multiple screens, including multiple instances of drivers
  • mixing different color depths and visuals on different and ideally even on the same screen
  • better control of the PCI device used
  • better config file parser
  • get rid of all VGA compatibility assumptions

Unless we find major deficiencies in the DIX layer, we should avoid making changes there.
