The future for Tyr
Summary
The article chronicles Tyr, a Rust-based GPU driver for Arm Mali, from sparse progress in early 2025 to a playable prototype by LPC and a plan to upstream in 2026. It emphasizes Rust as a path forward for kernel drivers, discusses missing abstractions like GEM shmem, GPUVM, and io-pgtable, and outlines power-management, GPU recovery, and Vulkan conformance challenges. The piece also sketches a potential future architecture (JobQueue) and upstream integration with Nova and PanVK.
