The Software Guard Extensions (SGX) support for the Linux kernel around the memory enclaves continues to be worked on by the open-source Intel team and is now up to their twenty-second revision but it's not clear that this code is ready yet for the upcoming Linux 5.4 cycle...
Given the recent talk about the Schedutil CPU frequency scaling governor and its future along with CPU frequency scaling behavior in general on AMD Zen 2 processors, here are some benchmarks of the Ryzen 9 3900X when tested with the different Linux "CPUFreq" governor options.
While most games/engines and software in general are moving from OpenGL to Vulkan, NVIDIA is still investing in their OpenGL driver stack and even adding new multi-GPU/SLI functionality to their driver and as part of that introducing new extensions...
Not included as part of our original EPYC 7742 / EPYC 7002 "Rome" Linux benchmarks was the NAS Parallel Benchmarks (NPB) developed by NASA. While an MPI testing favorite, there were build issues with the older version of NPB packaged by the Phoronix Test Suite. But with recently having updated that test profile against the latest NPB upstream, here are some results for the EPYC 7742 2P, EPYC 7601 2P, and dual Xeon Platinum 8280 benchmark results. Separately, there's also results now for NeatBench 5 with this video editing plug-in test case now part of the Phoronix Test Suite...
Red Hat's David Airlie has been refocusing efforts recently on improving the state of the LLVMpipe driver that implements OpenGL / OpenGL ES on top of CPUs using LLVM. In the past few weeks he's been wiring up more GL4 / GLES 3.1 extensions and this morning the latest achievement is supporting OpenGL compute shaders!..
The Schedutil CPU frequency scaling governor has been around for a few years and has gotten better over time but in our own tests we still find it frequently not being as competitive to the "performance" governor and others. However, in the future Schedutil might become the default and perhaps only governor...
While atomic mode-setting has been around for several years now and to provide a modern mode-setting interface that can test modes prior to the actual operation and reduce possible flickering during mode-setting events and also being faster, the common xf86-video-modesetting driver has at least temporarily disabled the support by default...

While we are often testing Intel's Clear Linux on high-end desktop and server hardware, it turns out even on the opposite end of the spectrum that their performance-optimized distribution can offer meaningful performance advantages on low-end SoCs for IoT-type devices. When testing Clear Linux with an Apollolake platform, it came out to being about 20% faster than the likes of Fedora and Ubuntu Linux.
Frequently brought up following our various Ryzen 3000 "Zen 2" benchmarks like the Ryzen 9 3900X vs. Core i9 9900K gaming benchmarks is how the Ryzen 9 3900X is pulling considerably more power than the similarly equipped Intel Core i9 system and those numbers are higher than what is often cited by Windows reviewers as the difference. I've begun investigating that power difference and indeed quite quickly could see Linux power usage being higher than Windows 10...
