Virtcon

Virtcon is the system terminal. It is a critical part of bringup and provides graphical output with minimal hardware requrements.

Design

Virtcon is written in Rust and powered by Carnelian. Carnelian enables advanced vector graphics and truetype text rendering while maintaining minimal hardware requirements.

Goals

  • Minimal resource usage.
  • Maximize code reuse with Terminal app.
  • Boot animation for startup and shutdown.
  • Runtime product configuration.
  • Flicker free single framebuffer mode.

Roadmap

  1. Boot animation chime support.
  2. Silent boot system for runtime suppression of chime.

Testing
