In July, Collabora announced
the Rust-based Tyr
GPU driver for Arm Mali
GPUs. Daniel Almeida has posted an update
on progress with a prototype of the driver running on a Rock 5B board
with the Rockchip RK3588 system-on-chip:

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

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

That said, this prototype can serve as an experimental driver and
as a testbed for all the Rust abstraction work taking place
upstream. It will let us experiment with different design decisions
and gather data on what truly contributes to the project's
objective.

There is also a video on
YouTube of the prototype in action.
