Ubuntu Blog Talks Up Rust Schedulers, Potential For Micro-Kernel Design Future
Ubuntu/Canonical has for a while now promoted the prospects of Rust programming within the Linux kernel and one of their kernel engineers, Andrea Righi, wrote a Rust-written Linux scheduler with promising results that leverages eBPF for dynamically loading it at run-time. While Ubuntu isn't yet committing to using it as part of their distribution, appearing on the Ubuntu blog today was more praise for the work and even talking about the potential for a "micro-kernel design" in the future via leveraging Rust and eBPF...

Reverse-Engineered NPU Driver Tantalizingly Close To Proprietary Driver Performance
When it comes to neural processing unit NPU/AI accelerators for Linux there is open-source options with the likes most notably of Intel-owned Habana Labs leading the way, Intel's iVPU driver for the NPU found within Meteor Lake SoCs, AMD recently posting a Ryzen AI Linux driver, etc. When it comes to reverse-engineered efforts, the Etnaviv project has expanded its scopes from just Vivante graphics IP to also embracing the Vivante NPU IP for running workloads like TensorFlow Lite. With the latest open-source achievements, the Etnaviv NPU performance is coming incredibly close to the proprietary and official driver...
