Racing karts on a Rust GPU kernel driver (Collabora blog)

In July, Collabora announcedthe Rust-based TyrGPU driver for Arm MaliGPUs. Daniel Almeida has posted an updateon progress with a prototype of the driver running on a Rock 5B boardwith the Rockchip RK3588 system-on-chip:

The Tyr prototype has progressed from basic GPU job execution torunning GNOME, Weston, and full-screen 3D games like SuperTuxKart,demonstrating a functional, high-performance Rust driver that matchesC-driver performance and paves the way for eventual upstreamintegration! [...]

Tyr is not ready to be used as a daily-driver, and it will stilltake time to replicate this upstream, although it is now clear that wewill surely get there. And as a mere prototype, it has a lot ofshortcuts that we would not have in an upstream version, even thoughit can run on top of an unmodified (i.e., upstream) version ofMesa.

That said, this prototype can serve as an experimental driver andas a testbed for all the Rust abstraction work taking placeupstream. It will let us experiment with different design decisionsand gather data on what truly contributes to the project'sobjective.

There is also a video onYouTube of the prototype in action.
