Tyr: a new Rust GPU driver
summary
Tyr is a new Rust kernel‑mode GPU driver for ARM Mali (tested on the G16) that implements IO‑MMU mappings, DRM VM and buffer management, CSF microcontroller boot/command submission plumbing, DMA‑fence sync and a scheduler so user space can upload command buffers. A downstream prototype boots GNOME and runs Firefox, drives games with similar frame rates to the C driver and has proven APIs that avoid unsafe where possible, but upstream boot of the firmware MCU is blocked by early memory allocation gaps.
