Intel Preps HWMON Support For Linux Driver To Expose Power / Voltage / Energy Reporting

Sat, 08/13/2022 - 02:21
While much of the Intel Arc Graphics "Alchemist" (DG2) support appears squared away for Linux 6.0 besides the support still being hidden behind the flag requiring i915.force_probe= to actually enable the experimental support, there still are various DG2 discrete GPU features being tackled by the open-source Intel kernel graphics drivers. One of those "extras" still working its way to the kernel is HWMON subsystem integration to be able to expose power / voltage / energy reporting...

LoongArch Enables PCI & Other Features For Linux 6.0

Fri, 08/12/2022 - 17:26
While support for the loongArch Chinese CPU architecture was merged in Linux 5.19, it wasn't actually enough to yield a booting system due to some driver code not yet being finished and ready for merging in time. LoongArch was allowed to merge that preliminary code in v5.19 so the Glibc support could land and now for Linux 6.0 more of the CPU port is ready to hit the kernel...

Asahi Linux May Pursue Writing Apple Silicon GPU Driver In Rust

Fri, 08/12/2022 - 01:55
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...
