ASUS TUF Laptops With Ryzen Are Now Patched To Stop Overheating On Linux
The AMD Ryzen Linux laptop experience continues improving albeit quite tardy on some elements of the support. In addition to the AMD Sensor Fusion Hub driver finally being released and current/voltage reporting for Zen CPUs on Linux, another step forward in Ryzen mobile support is a fix for ASUS TUF laptops with these processors.

AMD Sends In A Bunch Of Fixes For Linux 5.6 Along With Pollock Support
After already several rounds of feature work queued in DRM-Next for Linux 5.6, AMD has submitted a final batch of feature work for this next kernel as it concerns their AMDGPU graphics driver.
While Linux 5.6's merge window isn't opening until around the start of February, with RC6 having come, it effectively marks an end to the feature window of DRM-Next for targeting the next kernel. AMD's final pull request is mostly centered on fixes plus a few other extras and also enabling AMD Pollock display/graphics support for that forthcoming hardware.

The AMD Ryzen Thermal / Power Linux Reporting Improvements Working Well - V2 Up For Testing
A few days ago I reported on AMD's "k10temp" Linux kernel driver finally seeing the ability to report CCD temperatures and CPU current/voltage readings as a big improvement to this hardware monitoring driver. The work hasn't yet been queued for inclusion into the mainline kernel, but initial testing is working well and a second revision to the patches has been sent out.
Linux HWMON maintainer Guenter Roeck who spearheaded this work independent of AMD sent out the "v2" k10temp driver improvements on Saturday. This allows core complex tie temperature reporting for Zen 2 CPUs and allows current and voltage reporting for Ryzen CPUs. While this information has long been available to Windows users, sadly it's not been the case for Linux at least as far as mainline drivers go -- the out-of-tree Zenpower driver and other third-party attempts have been available but nothing mainline.

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. |
