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.

Back in late 2020 Intel's programming manuals detailed the Enhanced Hardware Feedback Interface for the CPU to provide guidance to the kernel's scheduler on optimal task placement of workloads. While marketed as Thread Director with the new 12th Gen Alder Lake processors, that hardware feedback interface support is getting squared away for the Linux kernel to improve the support for these newest processors...

Queued today within the Linux's random.git repository for the /dev/random and /dev/urandom code is support for using BLAKE2s rather than SHA1 when hashing the entropy pool. This in turn is a big performance speed-up in addition to being more secure...

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...

With a few lines of changed code updating some parameters, AMD Radeon graphics processors having the VCE video encoder block will be able to enjoy better performance...

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.

Ubuntu and parent company Canonical had another great year not only on the Linux desktop but continuing its commercial successes around the server, cloud, and IoT sectors too.

It was another exciting year for Intel on the open-source/Linux front with countless contributions to the Linux kernel, Mesa, and other open-source projects. Intel's oneAPI toolkits continue humming along and they continue maintaining tons of other projects from Clear Linux to SVT-AV1 to IWD and many more. Intel's Linux graphics driver developers have also been extremely busy preparing the open-source support for next year's discrete GPU launches. Here is a look at the most popular Intel articles on Phoronix during the course of 2021...

Earlier this month AMD released AOCC 3.2 as the newest version of their LLVM/Clang-based compiler focused on delivering optimized Zen performance. With our initial AMD AOCC 3.2 benchmarks on Zen 3, there is nice incremental improvement compared to the prior 3.x releases. But how does this AMD-optimized compiler stack up against the upstream LLVM Clang and GCC compilers? Here is a look at the AMD AOCC performance against the current Clang and GCC C/C++ compilers.
