Asahi Linux May Pursue Writing Apple Silicon GPU Driver In Rust
When it comes to the Apple M1 and M2 support on Linux, one of the biggest obstacles to suitable daily use for end-users is the current lack of GPU acceleration. Reverse engineering has been happening for the Apple Silicon graphics processor, early experiments being carried out under macOS and Asahi's m1n1 environment, and the next step will be to start writing a Direct Rendering Manager (DRM) kernel driver. To some surprise, the feasibility of writing this DRM kernel GPU driver in the Rust programming language is being explored.

Greg KH Recommends Avoiding Alder Lake Laptops - Intel Webcam Linux Driver Long Ways Out
Greg Kroah-Hartman as the Linux kernel's stable maintainer and effectively Linus Torvalds' second-in-command has suggested avoiding Intel Alder Lake laptops. While much of the Alder Lake laptop support for Linux is in good shape, the exception is around web cameras. These newer laptops with Intel's latest web-camera tech are not currently supported by the mainline kernel and require proprietary software for use. Some platforms like Ubuntu and ChromeOS are picking up these blobs for now while a proper open-source, upstream solution is likely months -- or likely about one year -- away.
