[$] Whither the Apple AGX graphics driver? Much of the early Rust code for the kernel has taken the form of reimplementations of existing drivers as a proof of concept. One project, though, is entirely new: the driver for Apple GPUs written by Asahi Lina. This driver has shipped with <a href="https://asahilinux.org/" rel="nofollow">Asahi Linux</a> for some time and, by many accounts, is stable, usable, and a shining example of how Rust can be used in a complex kernel subsystem. That driver remains outside of the mainline kernel, though, and merging currently looks like a distant prospect. The reasons for that state of affairs highlight some of the difficulties inherent in integrating a new language (and its associated development style) into the Linux kernel. https://lwn.net/Articles/988438/
