Back in 2020 Microsoft announced their "Pluton" security chip that woulld be coming to future AMD, Intel, and Qualcomm processors. The Pluton security processor is designed to improve the system security under Windows and now we find out that AMD's forthcoming Ryzen 6000 "Rembrandt" mobile processors will be the first featuring this security feature that may prove controversial to Linux/open-source fans...

Last week I called attention to the new "x86-android-tablets" driver being prepared for introduction in Linux 5.17. That driver aims to fix up the mess of various x86 Android-focused tablets failing to run off the mainline Linux kernel or having various device issues in doing so. Since that prior article, more patches have been posted to address additional tablet issues...

Next month marks two years since AMD introduced the Ryzen Threadripper 3990X 64-core / 128-thread processor. All of our testing of the 3990X on Linux over the past two years has been with the System76 Thelio Major, which continues holding up well with that US-assembled workstation with hand-crafted enclosure from Colorado. With System76 having recently released Pop!_OS 21.10 as the latest update to their Ubuntu Linux derived operating system and upcoming two year anniversary of the 3990X, it made for an interesting time to see how the performance of the Ryzen Threadripper 3990X and Radeon RX 5700 XT within that workstation has evolved.

Fedora had another successful year and anecdotally enthusiasm around the Red Hat sponsored Linux distribution grew a lot this year among Linux power users. As has been the case for years, Fedora releases have been among the first to feature new Linux innovations from the desktop down the stack -- many of which have been spearheaded by Red Hat engineers. Helping its cause for the past several years is that they have managed to deliver releases on-time (or close to it) and haven't been like some of the past distant releases that were rather buggy and other headaches stemming from the constant flow of changes. Fedora 34 and Fedora 35 this year were great releases and continued pushing the distribution on an upward trajectory...

AMD this week released AMDVLK 2021.Q4.3 as their last open-source Vulkan driver version of the year and with it came finally fixing the poor performance seen by that driver when running under Wayland such as with Ubuntu 21.04 and newer. Indeed, my tests have confirmed the AMDVLK performance now being in far better shape under Wayland, but is it enough to better compete now with Mesa's RADV alternative Vulkan driver? Here are fresh benchmarks.
