Briefings

Collabora's Tyr driver for Arm Mali GPUs was rewritten multiple times to align with evolving Rust kernel abstractions, creating a bottleneck where progress stalls until upstream design is finalized. This approach allows Tyr to expose specific requirements and limitations of the new Rust ecosystem, though it risks slower development compared to mature APIs.

Key points

• Tyr driver for Arm Mali GPUs was rewritten multiple times to align with evolving Rust kernel abstractions, causing progress to stall until upstream design is finalized.
• The driver interface revisions naturally lead to Tyr rewriting, which exposes specific requirements and limitations of the new Rust ecosystem.
