Kernel: AMD SMCA Updates, STM32MP1, and Rust

AMD SMCA Updates
Hi all, This set adds supports for SMCA changes in future AMD systems. Patch 1 adds an "unknown" bank type so that sysfs initialization issues can be avoided on systems with new bank types. Patch 2 adds new bank types and error descriptions used in future AMD systems. Patch 3 adjusts how SMCA bank information is cached. Future AMD systems will have different bank type layouts between logical CPUs. So having a single system-wide cache of the layout won't be correct. Thanks, Yazen

Updated Rust Code For Linux Kernel Patches Posted - Phoronix
In 2022 we will very likely see the experimental Rust programming language support within the Linux kernel mainlined. Sent out this morning were the updated patches introducing the initial support and infrastructure around handling of Rust within the kernel.
This summer saw the earlier patch series posted for review and discussion around introducing Rust programming language support in the Linux kernel to complement its longstanding C focus. In the months since there has been more progress on enabling Rust for the Linux kernel development, Linus Torvalds is not opposed to it, and others getting onboard with the effort. Rust for the Linux kernel remains of increasing interest to developers over security concerns with Rust affording more memory safety protections, potentially lowering the barrier to contributing to the kernel, and other related benefits.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
