The Collabora blog provides
an update on Tyr, a driver for Arm Mali GPUs.

One of our biggest challenges has been developing Tyr while the
Rust kernel abstractions and driver interfaces are also being
developed. As the driver interfaces are naturally revised and
improved, we have rewritten Tyr several times to adapt to the
larger Rust ecosystem. This not only makes progress much slower
than it would be with a mature API, but also stalls progress for
capabilities, such as job scheduling, while the abstraction is
properly designed, reviewed, tested, and merged upstream.

But working in this evolving environment is also precisely where
Tyr is able to provide the most value. As a user of these new Rust
abstractions, Tyr helps to expose their requirements and
limitations.
