Greg Kroah-Hartman today sent out the pull request of all the driver core updates for Linux 6.14, which ends up being a big deal for those interested in the prospects of Rust drivers for the Linux kernel.

With the Linux 6.13 kernel, Greg Kroah-Hartman described the level of Rust support as [1]a "tipping point" for Rust drivers with more of the Rust infrastructure having been merged. Now for the Linux 6.14 kernel, Greg describes the state of the Rust driver possibilities as " almost at the "write a real driver in rust" stage now, depending on what you want to do. "

As written about last month on Phoronix, as part of today's driver core pull request is [2]a lot of the PCI / platform device driver enablement for Rust code . Greg described the Rust driver core work in [3]the pull request as:

- driver core bindings for PCI, platform, OF, and some i/o functions. We are almost at the "write a real driver in rust" stage now, depending on what you want to do.

- misc device rust bindings and a sample driver to show how to use them

Linus Torvalds [4]merged this code alongside other driver core improvements today for the Linux 6.14 kernel.

We'll see what Linux 6.15 ends up holding in the Rust driver world...
